  • We describe an enantioselective synthesis of (3R,3aS,6aR)-hexahydrofuro[2,3-b]furan-3-ol which is a key subunit of darunavir, a widely used HIV-1 protease inhibitor drug for the treatment of HIV/AIDS patients. The synthesis was achieved in optically pure form utilizing commercially available sugar derivatives as the starting material. The key steps involve a highly stereoselective substrate-controlled hydrogenation, a Lewis acid catalyzed anomeric reduction of a 1,2-O-isopropylidene-protected glycofuranoside, and a Baeyer-Villiger oxidation of a tetrahydrofuranyl-2-aldehyde derivative. This optically active ligand alcohol was converted to darunavir efficiently.Catalysis oxidization has been known to be an effective technique in environmental remediation. However, low efficiency for oxygen activation and difficult recovery of the catalysts in powdery form significantly limit the practical application. In this work, a new-type monolithic α-Ni(OH)2/Ni-foam was fabricated by the hydrothermal process. We found that H atoms of α-Ni(OH)2 can significantly promote oxygen activation, which endows it with favorable NO and NO2 oxidization confirmed by theoretical calculation and in situ DRIFTS. Furthermore, the introduction of Ni foam accelerated the pollutant gas transfer and charge carriers' separation because of its abundant porous structure and high conductivity and its monolithic property simplified the recycling operation. Consequently, the obtained α-Ni(OH)2/Ni-foam achieved an excellent NO oxidation (69.0%) and no toxic NO2 was detected under visible light illumination (λ > 420 nm), indicating its highly promising potential in environmental remediation. Our work provides a conceptually different fresh perception to promote oxygen activation for highly efficient gas purification.The high-pressure equation of state (EOS) of energetic materials (EMs) is important for continuum and mesoscale models of detonation performance and initiation safety. Obtaining a high-fidelity EOS of the insensitive EM 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) has proven to be difficult because of challenges in experimental characterization at high pressures (HPs). In this work, powder X-ray diffraction patterns were fitted using the recently discovered monoclinic I2/a phase above 4 GPa, which shows that TATB is less compressible than when indexed with the triclinic P1̅ phase. First-principles calculations were performed with Perdew-Burke-Ernzerhof (PBE) and PBE0 functionals including thermal effects using the P1̅ phase. PBE0 improves the description of hydrogen bonding and thus predicts accurate planar a and b lattice parameters under ambient conditions. However, discrepancies in the predicted lattice parameters above 4-10 GPa compared with experimental measurements indexed with P1̅ are further evidence of a structural modification at high pressure. Layer sliding defects are formed during molecular dynamics simulations, which induces an anharmonic effect on the thermal expansion of the c lattice parameter. In short, the results provide several insights into determining high-fidelity EOS parameters for TATB and other molecular crystals.Using flat-histogram simulations, we calculate the entropy of molecular fluids along the vapor-liquid phase boundary. Our simulation approach is based on the evaluation of the canonical and grand-canonical partition functions, which, in turn, provide access to entropy through the statistical mechanics formalism. The results allow us to determine the critical entropy of molecular fluids and to uncover that the transition occurs symmetrically from an entropic standpoint. This can best be seen through the patterns exhibited by the thermodynamic variables temperature and pressure when plotted against the entropy of the coexisting phases. This behavior is found to hold for apolar, quadrupolar, and dipolar fluids. Finally, we identify functional forms that characterize the relation between thermodynamic variables and entropy along the coexistence curve up to the critical point.The NaIO4-mediated sequential iodination/amidation reaction of N-alkyl quinolinium iodide salts has been first developed. This cascade process provides an efficient way to rapidly synthesize 3-iodo-N-alkyl quinolinones with high regioselectivity and good functional group tolerance. This protocol was also amenable to the isoquinolinium salts, thus providing a complementary method for preparing the 4-iodo-N-alkyl isoquinolinones.Condensation particle counter (CPC) instruments are commonly used to detect atmospheric nanoparticles. They operate on the basis of condensing an organic working fluid on the nanoparticle seeds to grow the particles to a detectable size, and at the size of few nanometers, their efficiency depends on how well the working fluid interacts with the seeds under the measurement conditions. This study models the first steps of heterogeneous nucleation of two working fluids commonly used in CPCs (diethylene glycol (DEG) and n-butanol) onto two positively charged seeds, ammonium bisulfate and tetramethylammonium bromide. https://www.selleckchem.com/products/fluzoparib.html The nucleation process is modeled on a molecular level using a combination of systematic configurational sampling and density functional theory (DFT). We take into account the conformational flexibility of DEG and n-butanol and determine the key factors that can improve the efficiency of nanoparticle measurements by CPCs. The results show that hydrogen bonding between the seed and the working fluid mokely used for predicting preferences in similar nucleating systems.In the present study, we examined the inactivation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by synthetic conjugated polymers and oligomers developed in our laboratories as antimicrobials for bacteria, fungi, and nonenveloped viruses. The results show highly effective light-induced inactivation with several of these oligomers and polymers including irradiation with near-UV and visible light. In the best case, one oligomer induced a 5-log reduction in pfu/mL within 10 min. In general, the oligomers are more active than the polymers; however, the polymers are active with longer wavelength visible irradiation. Although not studied quantitatively, the results show that in the presence of the agents at concentrations similar to those used in the light studies, there is essentially no dark inactivation of the virus. Because three of the five materials/compounds examined are quaternary ammonium derivatives, this study indicates that conventional quaternary ammonium antimicrobials may not be active against SARS-CoV-2.

  • nearly all regain response upon resuming therapy. Therapy during pregnancy is rarely needed.Background The RESCUE (Randomized Evaluation of Patients with Stable Angina Comparing Utilization of Noninvasive Examinations) trial was a randomized, controlled, multicenter, comparative efficacy outcomes trial designed to assess whether initial testing with coronary computed tomographic angiography (CCTA) is noninferior to single photon emission computed tomography (SPECT) myocardial perfusion imaging in directing patients with stable angina to optimal medical therapy alone or optimal medical therapy with revascularization. Methods and Results The end point was first major adverse cardiovascular event (****) (cardiac death or myocardial infarction), or revascularization. Noninferiority margin for CCTA was set a priori as a hazard ratio (HR) of 1.3 (95% CI=0, 1.605). One thousand fifty participants from 44 sites were randomized to CCTA (n=518) or SPECT (n=532). Mean follow-up time was 16.2 (SD 7.9) months. There were no cardiac-related deaths. In patients with a negative CCTA there was 1 acute myocardial infgov/. Identifier NCT01262625.Background Peripheral artery disease (PAD) is a known risk factor for adverse outcomes in patients undergoing percutaneous coronary intervention. However, in some studies PAD is not an independent risk factor. https://www.selleckchem.com/products/tram-34.html We sought to examine the independent impact of PAD on a large prospective percutaneous coronary intervention registry. Methods and Results From our single-center prospective percutaneous coronary intervention registry, we have retrospectively analyzed 25 690 patients (years 2004-2018). We examined the influence of PAD on short- and long-term outcomes using both regression and propensity-matched analyses. Patients with documented PAD (n=1610, 6.3% of total) were older (66.7±10.8 versus 65.4±12.1, P less then 0.01), had higher rates of diabetes mellitus (69.3% versus 46.3%, P less then 0.01), hypertension (92.1% versus 76.1%, P less then 0.01) and renal failure (38.3% versus 18.2%, P less then 0.01). There were no differences in the rates of stable versus acute presentations, but less were treated with Prasugrel and Ticagrelor (3.3% versus 8.0% and 7.9% versus 11.9%, respectively, P less then 0.001 for both). Both 30-day and 3-year rates of all-cause death and major adverse cardiac events were higher for patients with PAD versus control (4.9% versus 2.1% and 7.3% versus 3.3% death and major adverse cardiac events at 30 days, respectively; 43.4% versus 29.0% and 55.0% versus 37.8%, respectively at 3 years, P less then 0.001 for all). Following multivariate analysis, the presence of PAD was associated with a higher risk of both death (hazard ratio [HR], 1.66; CI 1.52-1.83; P less then 0.001) and major adverse cardiac events (HR, 1.51; CI, 1.40-1.64; P less then 0.001). Conclusions PAD constitutes an independent risk factor for adverse outcomes in patients undergoing percutaneous coronary intervention. Further studies are needed to ascertain which effective therapies may mitigate this risk.Background Hypergravity may promote human hemostasis thereby increasing thrombotic risk. Future touristic suborbital spaceflight will expose older individuals with chronic medical conditions, who are at **** higher thromboembolic risk compared with professional astronauts, to hypergravity. Therefore, we tested the impact of hypergravity on hemostasis in healthy volunteers undergoing centrifugation. Methods and Results We studied 20 healthy seated men before and after 15 minutes under 3 Gz hypergravity on a long-arm centrifuge. We obtained blood samples for hemostasis testing before, immediately after, and 30 minutes after centrifugation. Tests included viscoelastic thromboelastometry, platelet impedance aggregometry, endothelial activation markers, blood rheology testing, microparticle analyses, and clotting factor analysis. Exposure to hypergravity reduced plasma volume by 12.5% (P=0.002) and increased the red blood cell aggregation index (P less then 0.05). With hypergravity, thrombelastographic clotting tiibitors release. Hemoconcentration may contribute to the response.Background tPA (tissue-type plasminogen activator) remains the only approved drug for acute ischemic stroke, with a potentially serious adverse effect hemorrhagic transformation. The effects of antithrombotic agents on tPA-induced hemorrhagic transformation after ischemic stroke are not clearly defined. We performed a systematic review and meta-analysis in preclinical studies aiming to evaluate the efficacy of antithrombotic agents on tPA-induced hemorrhagic transformation after ischemic stroke. Methods and Results We conducted a systematic review and meta-analysis of studies testing antithrombotic agents in animal models of tPA-induced hemorrhagic transformation. The pooled effects were calculated using random-effects models, and heterogeneity was explored through meta-regression and subgroup analyses. Publication bias was assessed using trim and fill method and the Egger test. The efficacy of 18 distinct interventions was described in 22 publications. The pooled data showed a significant improvement in cerebral hemorrhage, infarct size, and neurobehavioral outcome in treated compared with control animals (standardized mean difference, 0.45 [95% CI, 0.11-0.78]; standardized mean difference, 1.18 [95% CI, 0.73-1.64]; and standardized mean difference, 0.91 [95% CI, 0.49-1.32], respectively). Subgroup analysis indicated that quality score, random allocation, control of temperature, anesthetic used, stroke model used, route of drug delivery, time of drug administration, and time of assessment were significant factors that influenced the effects of interventions. Conclusions Administration with antiplatelet agents revealed statistically significant improvement in all the outcomes. Anticoagulant agents showed significant effects in infarct size and neurobehavioral score, but fibrinolytic agents did not show any significant improvement in all the outcomes. The conclusions should be interpreted cautiously given the heterogeneity and publication bias identified in this analysis.

  • Based on all the available evidence, we hypothesize that Marat may have suffered from a fungal infection (seborrheic dermatitis), possibly superinfected with bacterial opportunistic pathogens. BACKGROUND & AIMS In patients with autoimmune atrophic gastritis and achlorhydria, hypergastrinemia is associated with development of type-1 gastric neuroendocrine tumors (gNETs). Twelve months' treatment with netazepide (YF476), an antagonist of the cholecystokinin B receptor (CCKBR or CCK2R), eradicated some type-1 gNETs in patients. We investigated the mechanisms by which netazepide induces gNET regression using gene expression profiling. METHODS We obtained serum samples and gastric corpus biopsies from 8 patients with hypergastrinemia and type-1 gNETs enrolled in a phase 2 trial of netazepide. Control samples were obtained from 10 patients without gastric cancer. We used amplified and biotinylated sense-strand DNA targets from total RNA and Affymetrix Human Gene 2.0 ST microarrays to identify differentially expressed genes in stomach tissues from patients with type-1 gNETs before, during, and after netazepide treatment. Findings were validated in a human AGSGR gastric adenocarcinoma cell line that stablyn and cleavage of IGFBP3 and IGFBP5. CONCLUSIONS In an analysis of human gNETS and ****, we found that gastrin upregulates expression of gastric PAPPA2. Increased PAPPA2 alters IGF bioavailability, cell migration, and tissue remodeling, which are involved in type-1 gNET development. These effects are inhibited by netazepide. BACKGROUND & AIMS The inflammatory response to intestinal damage promotes healing through mechanisms that are incompletely understood. Gene expression of cluster of differentiation 74 (CD74), the receptor for cytokine macrophage migration inhibitory factor, is increased in patients with inflammatory bowel disease (IBD), however, the role of CD74 signaling in intestinal inflammation remains poorly understood. The aim of this study was to determine the functional role of CD74 signaling in intestinal inflammation. METHODS We studied the characteristics of CD74 protein expression in human IBD and experimental colitis. The functional role of CD74 signaling in the intestine was investigated using cellular models; wild-type, CD74-/-, and bone marrow chimera ****; neutralizing anti-CD74 antibodies; flow cytometry; immunohistochemistry; immunofluorescence; immunoblotting; and clustered regularly interspaced short palindromic repeats and associated protein 9 technology. RESULTS In IBD patients and experimental colitis,The effects of moderate thermosonication (MTS) on the quality quartet physico-chemical, microbial, nutritional and sensory qualities of orange juice (OJ) inoculated with Alicyclobacillus acidoterrestris (AAT) were studied during 24 days of storage at ambient and refrigerated temperatures. The bioactive compounds and antioxidant activity of OJ decreased with storage, while the pectin methyl esterase (PME) increased. Nonetheless, noticeable changes were observed from the 12th day of storage. There was no obvious (p > 0.05) variation in pH and total soluble solids. To determine the nutritional and microbial quality characteristics of OJ during storage, non-linear kinetic curves were successfully fitted with least square fitting polynomial and four-parameter log-logistic distribution models. The E-nose sensors succeeded in discriminating between the aroma of non-treated and treated OJ based on linear discriminant analysis (LDA). Furthermore, terpenes, alcohol and partially aromatic compounds were the main spoilage indicators of OJ during storage based on E-nose analysis and confirmed by HS-SPME-GC/MS analysis. Thus, MTS significantly extended the shelf life of the quality quartet of natural OJ at 4 °C. E-nose-GC/MS fusion offered odor fingerprints to AAT microorganisms that can be used as spoilage index without using traditional food analysis techniques. The proposed approach can be used as an alternative tool for rapid detection of spoilage microorganisms in OJ. It is widely accepted that the hypoxic nature of solid tumors contribute to their resistance to radiation therapy. There is increasing evidence that cyclooxygenase-2 (COX-2) contributes to increased resistance of tumors to radiation therapy. Several studies demonstrate that combination of COX-2 selective inhibitors with radiation therapy selectively enhances radio responsiveness of tumor cells. However, the majority of these studies utilised suprapharmacological concentrations under normoxic conditions only. Furthermore, the mechanism by which these agents act remain largely unclear. Therefore, the aim of this study was to determine the impact of COX-2 selective inhibitors on both normoxic and hypoxic radiosensitivity in vitro and the mechanisms underlying this. https://www.selleckchem.com/products/tpx-0046.html Because of the close, reciprocal relationship between COX-2 and p53 we investigated their contribution to radioresistance. To achieve this we exposed HeLa, MCF-7 and MeWo cells to the COX-2 selective inhibitor, NS398 (10μM). NS398 (10μM) selectively sensitized hypoxic HeLa and MCF-7 but not MeWo cells to ionising radiation (5 Gy). Furthermore, while knockdown of COX-2 with siRNA did not affect either normoxic radiosensitivity in HeLa cells, the radiosensitisation observed with NS398 was lost suggesting both COX-2 dependent and independent mechanisms. We also show that ionising radiation at 5 Gy results in phosphorylation of p53 at serine 15, a key phosphorylation site for p53-mediated apoptosis, and that hypoxia attenuates this phosphorylation. Attenuated phosphorylation of p53 under hypoxic conditions may therefore contribute to hypoxic radioresistance. We also show that NS398 selectively phosphorylates p53 under hypoxic conditions following irradiation at 5 Gy. p53 phosphorylation could be an underlying mechanism by which this agent and other COX-2 inhibitors sensitize tumors to radiation therapy. Toxoplasma gondii is a protozoan parasite that infects almost all species of mammals and birds, including fur-bearing animals. However, the prevalence of T. gondii among Russian fur-bearing animals is unknown. In this study, the seroprevalence of T. gondii in European mink in Russia was investigated. In total, 100, 119 and 61 serum samples were collected from a fur farm, located in the Republic of Tatarstan, Russia, in autumn 2016, 2017 and 2018, respectively. The seroprevalence of T. gondii in 2016, 2017 and 2018 was 32% (23.2%-42.2%, 95% confidence interval [CI]), 31.1% (23.1%-40.3%, 95% CI) and 41.0% (28.8%-54.3%, 95% CI), respectively. In total, 50 brain samples from 100 animals whose blood was sampled in 2016 were analyzed by PCR to detect T. gondii DNA. T. gondii DNA was detected in 14% (7/50) of the mink brain samples. To examine single nucleotide polymorphisms (SNPs) in the partial B1 gene, we sequenced an 836-bp fragment, which contains a few SNPs, from the detected T. gondii DNA. The sequences of the fragments were identical to those of two of the major lineages, Type II and Type III, but differed from that of the Type I lineage.

Nonetheless, noticeable changes were observed from the 12th day of storage. There was no obvious (p > 0.05) variation in pH and total soluble solids. To determine the nutritional and microbial quality characteristics of OJ during storage, non-linear kinetic curves were successfully fitted with least square fitting polynomial and four-parameter log-logistic distribution models. The E-nose sensors succeeded in discriminating between the aroma of non-treated and treated OJ based on linear discriminant analysis (LDA). Furthermore, terpenes, alcohol and partially aromatic compounds were the main spoilage indicators of OJ during storage based on E-nose analysis and confirmed by HS-SPME-GC/MS analysis. Thus, MTS significantly extended the shelf life of the quality quartet of natural OJ at 4 °C. E-nose-GC/MS fusion offered odor fingerprints to AAT microorganisms that can be used as spoilage index without using traditional food analysis techniques. The proposed approach can be used as an alternative tool for rapid detection of spoilage microorganisms in OJ. It is widely accepted that the hypoxic nature of solid tumors contribute to their resistance to radiation therapy. There is increasing evidence that cyclooxygenase-2 (COX-2) contributes to increased resistance of tumors to radiation therapy. Several studies demonstrate that combination of COX-2 selective inhibitors with radiation therapy selectively enhances radio responsiveness of tumor cells. However, the majority of these studies utilised suprapharmacological concentrations under normoxic conditions only. Furthermore, the mechanism by which these agents act remain largely unclear. Therefore, the aim of this study was to determine the impact of COX-2 selective inhibitors on both normoxic and hypoxic radiosensitivity in vitro and the mechanisms underlying this. https://www.selleckchem.com/products/tpx-0046.html Because of the close, reciprocal relationship between COX-2 and p53 we investigated their contribution to radioresistance. To achieve this we exposed HeLa, MCF-7 and MeWo cells to the COX-2 selective inhibitor, NS398 (10μM). NS398 (10μM) selectively sensitized hypoxic HeLa and MCF-7 but not MeWo cells to ionising radiation (5 Gy). Furthermore, while knockdown of COX-2 with siRNA did not affect either normoxic radiosensitivity in HeLa cells, the radiosensitisation observed with NS398 was lost suggesting both COX-2 dependent and independent mechanisms. We also show that ionising radiation at 5 Gy results in phosphorylation of p53 at serine 15, a key phosphorylation site for p53-mediated apoptosis, and that hypoxia attenuates this phosphorylation. Attenuated phosphorylation of p53 under hypoxic conditions may therefore contribute to hypoxic radioresistance. We also show that NS398 selectively phosphorylates p53 under hypoxic conditions following irradiation at 5 Gy. p53 phosphorylation could be an underlying mechanism by which this agent and other COX-2 inhibitors sensitize tumors to radiation therapy. Toxoplasma gondii is a protozoan parasite that infects almost all species of mammals and birds, including fur-bearing animals. However, the prevalence of T. gondii among Russian fur-bearing animals is unknown. In this study, the seroprevalence of T. gondii in European mink in Russia was investigated. In total, 100, 119 and 61 serum samples were collected from a fur farm, located in the Republic of Tatarstan, Russia, in autumn 2016, 2017 and 2018, respectively. The seroprevalence of T. gondii in 2016, 2017 and 2018 was 32% (23.2%-42.2%, 95% confidence interval [CI]), 31.1% (23.1%-40.3%, 95% CI) and 41.0% (28.8%-54.3%, 95% CI), respectively. In total, 50 brain samples from 100 animals whose blood was sampled in 2016 were analyzed by PCR to detect T. gondii DNA. T. gondii DNA was detected in 14% (7/50) of the mink brain samples. To examine single nucleotide polymorphisms (SNPs) in the partial B1 gene, we sequenced an 836-bp fragment, which contains a few SNPs, from the detected T. gondii DNA. The sequences of the fragments were identical to those of two of the major lineages, Type II and Type III, but differed from that of the Type I lineage.

  • Also, ncRv11875C showed expression in the iron-limited condition, which is prevalent inside the macrophages of the host cells. CONCLUSION The systems level analysis of sRNA highlights the condition-specific expression of sRNAs which might enable the pathogen survival by rewiring regulatory circuits.BACKGROUND The aberrant expression of microRNAs is closely connected to the occurrence and development of a great deal of human diseases. To study human diseases, numerous effective computational models that are valuable and meaningful have been presented by researchers. RESULTS Here, we present a computational framework based on graph Laplacian regularized L2, 1-nonnegative matrix factorization (GRL2, 1-NMF) for inferring possible human disease-connected miRNAs. First, manually validated disease-connected microRNAs were integrated, and microRNA functional similarity information along with two kinds of disease semantic similarities were calculated. Next, we measured Gaussian interaction profile (GIP) kernel similarities for both diseases and microRNAs. Then, we adopted a preprocessing step, namely, weighted K nearest known neighbours (WKNKN), to decrease the sparsity of the miRNA-disease association matrix network. Finally, the GRL2,1-NMF framework was used to predict links between microRNAs and diseases. CONCLUSIONS The new method (GRL2, 1-NMF) achieved AUC values of 0.9280 and 0.9276 in global leave-one-out cross validation (global LOOCV) and five-fold cross validation (5-CV), respectively, showing that GRL2, 1-NMF can powerfully discover potential disease-related miRNAs, even if there is no known associated disease.BACKGROUND The interactions between non-coding RNAs (ncRNA) and proteins play an essential role in many biological processes. Several high-throughput experimental methods have been applied to detect ncRNA-protein interactions. However, these methods are time-consuming and expensive. Accurate and efficient computational methods can assist and accelerate the study of ncRNA-protein interactions. RESULTS In this work, we develop a stacking ensemble computational framework, RPI-SE, for effectively predicting ncRNA-protein interactions. More specifically, to fully exploit protein and RNA sequence feature, Position Weight Matrix combined with Legendre Moments is applied to obtain protein evolutionary information. Meanwhile, k-mer sparse matrix is employed to extract efficient feature of ncRNA sequences. Finally, an ensemble learning framework integrated different types of base classifier is developed to predict ncRNA-protein interactions using these discriminative features. The accuracy and robustness of RPI-SE was evaluated on three benchmark data sets under five-fold cross-validation and compared with other state-of-the-art methods. CONCLUSIONS The results demonstrate that RPI-SE is competent for ncRNA-protein interactions prediction task with high accuracy and robustness. It's anticipated that this work can provide a computational prediction tool to advance ncRNA-protein interactions related biomedical research.BACKGROUND Taxus cells are a potential sustainable and environment-friendly source of taxol, but they have low survival ratios and slow grow rates. Despite these limitations, Taxus callus cells induced through 6 months of culture contain more taxol than their parent tissues. In this work, we utilized 6-month-old Taxus media calli to investigate their regulatory mechanisms of taxol biosynthesis by applying multiomics technologies. Our results provide insights into the adaptation strategies of T. media by transcriptional reprogramming when induced into calli from parent tissues. RESULTS Seven out of 12 known taxol, most of flavonoid and phenylpropanoid biosynthesis genes were significantly upregulated in callus cells relative to that in the parent tissue, thus indicating that secondary metabolism is significantly strengthened. The expression of genes involved in pathways metabolizing biological materials, such as amino acids and sugars, also dramatically increased because all nutrients are supplied from the medN Our results suggest that increasing the biosynthesis of taxol and other secondary metabolites is an active regulatory measure of calli to adapt to heterotrophic culture, and this alteration mainly involved direct and indirect miRNA-induced transcriptional reprogramming. These results expand our understanding of the relationships among the metabolism of biological substances, the biosynthesis of secondary metabolites, and defense systems. They also provide a series of candidate miRNAs and transcription factors for taxol biosynthesis.BACKGROUND The tumor suppressor p53 is a major regulator of the DNA damage response and has been suggested to selectively bind and activate cell-type specific gene expression programs. However recent studies and meta-analyses of genomic data propose largely uniform, and condition independent p53 binding and thus question the selective and cell-type dependent function of p53. RESULTS To systematically assess the cell-type specificity of p53, we measured its association with DNA in 12 p53 wild-type cancer cell lines, from a range of epithelial linages, in response to ionizing radiation. We found that the majority of bound sites were occupied across all cell lines, however we also identified a subset of binding sites that were specific to one or a few cell lines. Unlike the shared p53-bound genome, which was not dependent on chromatin accessibility, the association of p53 with these atypical binding sites was well explained by chromatin accessibility and could be modulated by forcing cell state changes such as the epithelial-to-mesenchymal transition. CONCLUSIONS Our study reconciles previous conflicting views in the p53 field, by demonstrating that although the majority of p53 DNA binding is conserved across cell types, there is a small set of cell line specific binding sites that depend on cell state.BACKGROUND The virulence of the plant pathogen Xanthomonas campestris pv. https://www.selleckchem.com/products/cytidine.html campestris (Xcc) involves the coordinate expression of many virulence factors, including surface appendages flagellum and type IV pili, which are required for pathogenesis and the colonization of host tissues. Despite many insights gained on the structure and functions played by flagellum and pili in motility, biofilm formation, surface attachment and interactions with bacteriophages, we know little about how these appendages are regulated in Xcc. RESULTS Here we present evidence demonstrating the role of two single domain response regulators PilG and PilH in the antagonistic control of flagellum-dependent (swimming) and pili-dependent (swarming) motility. Using informative mutagenesis, we reveal PilG positively regulates swimming motility while and negatively regulating swarming motility. Conversely, PilH negatively regulates swimming behaviour while and positively regulating swarming motility. By transcriptome analyses (RNA-seq and RT-PCR) we confirm these observations as PilG is shown to upregulate many genes involved chemotaxis and flagellar biosynthesis but these similar genes were downregulated by PilH.

  • (PsycInfo Database Record (c) 2021 APA, all rights reserved).Temporal dynamics in attention bias (AB) have gained increasing attention in recent years. It has been proposed that AB is variable over trials within a single test session of the dot-probe task, and that the variability in AB is more predictive of psychopathology than the traditional mean AB score. More important, one of the dynamics indices has shown better reliability than the traditional mean AB score. However, it has been also suggested that the dynamics indices are unable to uncouple random measurement error from true variability in AB, which questions the estimation precision of the dynamics indices. To clarify and overcome this issue, the current article introduces a state-space modeling (SSM) approach to estimate trial-level AB more accurately by filtering random measurement error. The estimation error of the extant dynamics indices versus SSM were evaluated by computer simulations with different parameter settings for the temporal variability and between-person variance in AB. Throughout the simulations, SSM showed robustly lower estimation error than the extant dynamics indices. We also applied these indices to real data sets, which revealed that the dynamics indices overestimate within-person variability relative to SSM. Here SSM indicated less temporal dynamics in AB than previously proposed. These findings suggest that SSM might be a better alternative to estimate trial level AB than the extant dynamics indices. However, it is still unclear whether AB has meaningful in-session variability that is predictive of psychopathology.

Affective inhibitory control constitutes an important part of emotion regulation and involves the ability to regulate automatic or prepotent responses to irrelevant and potentially distracting emotional information. The aim of the present study was to investigate the role of affective inhibitory control in the relationship between exposure to child maltreatment and internalizing problems in adolescence. A nationally representative sample of adolescents (n = 9,240; 49% girls; Mage = 14 years; SD = 0.9), of which n = 4,261 (55% girls; Mage = 14 years; SD = 0.9) were exposed to child maltreatment, conducted an emotional go/no-go task. Participants were presented with angry facial expressions as emotional no-go stimuli in order to examine their ability to inhibit behavioral responses to threatening task-irrelevant stimuli. Affective inhibitory control problems were uniquely related to internalizing problems in maltreated adolescents. Gender effects were observed; the relationship was significant in girls but not in boys. Moreover, affective inhibitory control moderated the relationship between exposure to psychological abuse and internalizing problems in girls. We did not observe any relationship between inhibitory control and internalizing problems when neutral faces were presented as task-irrelevant information. Findings suggest that a reduced ability to inhibit threatening, but task-irrelevant, information is related to internalizing problems in maltreated adolescent girls. Results highlight the importance of affective inhibitory control as a potential moderating mechanism in individual risk for experiencing internalizing problems in abused adolescents. (PsycInfo Database Record (c) 2021 APA, all rights reserved).Adolescence is a developmental period characterized by remarkable volatility and comorbidity in internalizing disorders. Delineating internalizing symptom change in a manner that accounts for symptoms' shared versus distinctive features is imperative to an understanding of their development. An additional question concerns how vulnerabilities for internalizing disorders relate to development of internalizing symptoms. Cross-sectional and prospective associations between neuroticism and internalizing psychopathology are well-established, yet conclusive evidence on neuroticism's relation to the progression of symptom dimensions relevant to internalizing disorders remains absent. In this investigation, we used latent growth curve modeling to characterize the trajectories of tri-level model internalizing dimensions (General Distress, Anhedonia-Apprehension, Fears, Anxious Arousal, Fears of Specific Stimuli, Social Fears, Narrow Depression, Interoceptive/Agoraphobic Fears) and examined whether a general neuroticism factor predicted their growth. We used anxiety and depressive symptom data spanning 6 years, collected from 606 high school juniors mostly vulnerable for internalizing disorders. We observed a pattern of results that varied by symptom dimension. Only Anhedonia-Apprehension showed a distinct increasing trend, on average. Neuroticism predicted an adverse symptom course for the dimension of General Distress. Our results reinforce the notion that neuroticism confers substantial risk for internalizing symptom maintenance and extend past findings by demonstrating that neuroticism forecasts a poor symptom course for General Distress but not narrower dimensions of internalizing.

In the current study, we gave chimpanzees the opportunity to instrumentally help a conspecific to obtain food. https://www.selleckchem.com/products/caerulein.html Following recent studies with human children, we measured their pupil diameter at various points in the process. Like young children, chimpanzees' pupil diameter decreased soon after they had helped. However, unlike children, chimpanzees' pupils remained more dilated upon watching a third party provide the needed help instead of them. Our interpretation is that chimpanzees are motivated to help others, and the evolutionary basis is direct or indirect reciprocity, as providing help oneself sets the conditions for a payback. This is in contrast to young children whose goal is to see others being helped-by whomever-presumably because their helping is not based on reciprocity.

  • nov. is proposed. The type strain is UKS-15T (=JCM 30983T=KACC 18719T).So far it has never been clearly decided whether the treatise De natura rerum constitutes an authentic work by the physician and natural philosopher Theophrastus Bombast of Hohenheim, called Paracelsus (1493/94-1541) This article outlines the manuscript and printing traditions of De natura rerum, in which a recently discovered manuscript from 1571 is identified as the earliest source. The watermarks of this manuscript refer to the Tyrolean Inn Valley, where great alchemical expertise was available due to silver mining. A detailed examination of the content and style of the preface and the nine chapters indicates the involvement of at least three different authors. Some of these parts are definitely forgeries, while others cannot be judged with certainty as to their authenticity. https://www.selleckchem.com/products/tinengotinib.html On the other hand, three chapters, those on death, resuscitation and the signature of natural things, are most likely real writings of Paracelsus.A scholarly consensus has long held that in redefining alchemy, Paracelsus rejected metallic transmutation. I show here, however, that for most of his career Paracelsus believed that it was possible to change one metal into another, and even late in his short life he did not break with that view. Furthermore, in certain places in his works he also represented himself, occasionally directly and more often obliquely, as a practical transmutationist. Because Paracelsus not only acknowledged that metallic transmutations were theoretically possible but also claimed to have carried them out in practice, we must regard him as (among other things) a transmutational alchemist. As such, he had more in common than historians have generally admitted with both his medieval predecessors and his posthumous followers. The Paracelsian alchemists of the late-sixteenth and seventeenth centuries were not wrong to situate Paracelsus within the alchemical tradition, nor to connect their own goldmaking interests to his.As William R. Newman has already shown, the alchemical homunculus described in the pseudo-Paracelsian writing De natura rerum was not the only kind of "homunculus" present in the works of (or attributed to) Paracelsus. Two other important kinds of "homunculi" indeed appeared in other treatises one in De homunculis et monstris and the other in both Vom langen Leben and the Liber de imaginibus. This article focuses on the latter tract and its relationships with De natura rerum. After discussing the authenticity of the Liber de imaginibus, I will provide a brief analysis of its content and discuss the major topics common to the two treatises the "signatures of things" and the homunculus. By studying the reception of the latter, I will show how the alchemical conception of the homunculus, as explained in De natura rerum, quickly established itself as the most prominent notion despite the fact that the golem-like version of Vom langen Leben and De imaginibus had nearly as **** success at first among Paracelsians.The basilisk of the pseudo-Paracelsian De natura rerum is the evil twin of the homunculus. Created from menstrual blood by artificial ectogenesis in an alchemical laboratory, the basilisk embodies the poisonous character traditionally ascribed to catamenial women, but magnified and concentrated by its mode of generation to the degree that it can kill by its glance alone. How does this remarkable thought experiment relate to other instances of the basilisk in the genuine and pseudonymous corpus of Paracelsus? The present paper outlines two primary uses which emerge repeatedly first, in works other than De natura rerum, the basilisk is used by Paracelsus and his imitators as a means of explaining action at a distance, especially in the case of plague. Relying on a medieval association between the basilisk's deadly gaze and the putative ability of menstruating women to damage mirrors, the genuine Paracelsus links contagious disease to the deleterious action of the female imagination. Second, because the basilisk was traditionally held to be the product of an unnatural birth, being born from an egg laid by a rooster and incubated by a toad, the Paracelsian corpus frequently invokes the monster as a model for unnatural generation in general.Purpose The purpose of this study was to understand how first generation Latino parents, whose primary language is Spanish and live in a colonia on the U.S.-Mexico border, use screen time in their homes.Methods A purposeful sampling approach was used to recruit eligible parents of pre-adolescents (ages 9-14) who were native Spanish speakers, and living on the U.S.-Mexico border. Three focus groups in Spanish (two with mothers and one with fathers) were conducted. Data were codified using a general inductive approach based on grounded theory. A consensus process was repeated until a final codebook was developed.Results Screen time allowed parents to foster familismo (family cohesiveness and bonding) and respeto (respect). Parents knew that a healthy balance of media use is important, but broader social contexts (marital discord and economics) challenged the enforcement of familial screen time rules and parents were often permissive.Conclusions Our study addressed research gaps by examining the understudied social and cultural contexts (practices, routines, rules, and beliefs) that shape children's screen time use among a sample of Latino immigrants living on the U.S.-Mexico border. This sample of parents indicated that familismo and respeto (i.e., cohesiveness and bonding) influence familial decision-making including screen time.Social media have become a common way for people to express their personal viewpoints, including sentiments about health topics. We present the results of an opinion mining analysis on vaccination performed on Twitter from September 2016 to August 2017 in Italy. Vaccine-related tweets were automatically classified as against, in favor or neutral in respect of the vaccination topic by means of supervised machine-learning techniques. During this period, we found an increasing trend in the number of tweets on this topic. According to the overall analysis by category, 60% of tweets were classified as neutral, 23% against vaccination, and 17% in favor of vaccination. Vaccine-related events appeared able to influence the number and the opinion polarity of tweets. In particular, the approval of the decree introducing mandatory immunization for selected childhood diseases produced a prominent effect in the social discussion in terms of number of tweets. Opinion mining analysis based on Twitter showed to be a potentially useful and timely sentinel system to assess the orientation of public opinion toward vaccination and, in future, it may effectively contribute to the development of appropriate communication and information strategies.

A detailed examination of the content and style of the preface and the nine chapters indicates the involvement of at least three different authors. Some of these parts are definitely forgeries, while others cannot be judged with certainty as to their authenticity. https://www.selleckchem.com/products/tinengotinib.html On the other hand, three chapters, those on death, resuscitation and the signature of natural things, are most likely real writings of Paracelsus.A scholarly consensus has long held that in redefining alchemy, Paracelsus rejected metallic transmutation. I show here, however, that for most of his career Paracelsus believed that it was possible to change one metal into another, and even late in his short life he did not break with that view. Furthermore, in certain places in his works he also represented himself, occasionally directly and more often obliquely, as a practical transmutationist. Because Paracelsus not only acknowledged that metallic transmutations were theoretically possible but also claimed to have carried them out in practice, we must regard him as (among other things) a transmutational alchemist. As such, he had more in common than historians have generally admitted with both his medieval predecessors and his posthumous followers. The Paracelsian alchemists of the late-sixteenth and seventeenth centuries were not wrong to situate Paracelsus within the alchemical tradition, nor to connect their own goldmaking interests to his.As William R. Newman has already shown, the alchemical homunculus described in the pseudo-Paracelsian writing De natura rerum was not the only kind of "homunculus" present in the works of (or attributed to) Paracelsus. Two other important kinds of "homunculi" indeed appeared in other treatises one in De homunculis et monstris and the other in both Vom langen Leben and the Liber de imaginibus. This article focuses on the latter tract and its relationships with De natura rerum. After discussing the authenticity of the Liber de imaginibus, I will provide a brief analysis of its content and discuss the major topics common to the two treatises the "signatures of things" and the homunculus. By studying the reception of the latter, I will show how the alchemical conception of the homunculus, as explained in De natura rerum, quickly established itself as the most prominent notion despite the fact that the golem-like version of Vom langen Leben and De imaginibus had nearly as much success at first among Paracelsians.The basilisk of the pseudo-Paracelsian De natura rerum is the evil twin of the homunculus. Created from menstrual blood by artificial ectogenesis in an alchemical laboratory, the basilisk embodies the poisonous character traditionally ascribed to catamenial women, but magnified and concentrated by its mode of generation to the degree that it can kill by its glance alone. How does this remarkable thought experiment relate to other instances of the basilisk in the genuine and pseudonymous corpus of Paracelsus? The present paper outlines two primary uses which emerge repeatedly first, in works other than De natura rerum, the basilisk is used by Paracelsus and his imitators as a means of explaining action at a distance, especially in the case of plague. Relying on a medieval association between the basilisk's deadly gaze and the putative ability of menstruating women to damage mirrors, the genuine Paracelsus links contagious disease to the deleterious action of the female imagination. Second, because the basilisk was traditionally held to be the product of an unnatural birth, being born from an egg laid by a rooster and incubated by a toad, the Paracelsian corpus frequently invokes the monster as a model for unnatural generation in general.Purpose The purpose of this study was to understand how first generation Latino parents, whose primary language is Spanish and live in a colonia on the U.S.-Mexico border, use screen time in their homes.Methods A purposeful sampling approach was used to recruit eligible parents of pre-adolescents (ages 9-14) who were native Spanish speakers, and living on the U.S.-Mexico border. Three focus groups in Spanish (two with mothers and one with fathers) were conducted. Data were codified using a general inductive approach based on grounded theory. A consensus process was repeated until a final codebook was developed.Results Screen time allowed parents to foster familismo (family cohesiveness and bonding) and respeto (respect). Parents knew that a healthy balance of media use is important, but broader social contexts (marital discord and economics) challenged the enforcement of familial screen time rules and parents were often permissive.Conclusions Our study addressed research gaps by examining the understudied social and cultural contexts (practices, routines, rules, and beliefs) that shape children's screen time use among a sample of Latino immigrants living on the U.S.-Mexico border. This sample of parents indicated that familismo and respeto (i.e., cohesiveness and bonding) influence familial decision-making including screen time.Social media have become a common way for people to express their personal viewpoints, including sentiments about health topics. We present the results of an opinion mining analysis on vaccination performed on Twitter from September 2016 to August 2017 in Italy. Vaccine-related tweets were automatically classified as against, in favor or neutral in respect of the vaccination topic by means of supervised machine-learning techniques. During this period, we found an increasing trend in the number of tweets on this topic. According to the overall analysis by category, 60% of tweets were classified as neutral, 23% against vaccination, and 17% in favor of vaccination. Vaccine-related events appeared able to influence the number and the opinion polarity of tweets. In particular, the approval of the decree introducing mandatory immunization for selected childhood diseases produced a prominent effect in the social discussion in terms of number of tweets. Opinion mining analysis based on Twitter showed to be a potentially useful and timely sentinel system to assess the orientation of public opinion toward vaccination and, in future, it may effectively contribute to the development of appropriate communication and information strategies.

  • Conclusion The results reflect the participants' perspective on what is meaningful to them when trying to quit smoking and adds important knowledge to future smoking cessation studies in this patient group.An external focus of attention can improve performance, but there is little research on effects for the elderly in every day, well-learned mobility tasks. 57 older and 59 young adults performed the sit-to-stand and stand-to-sit while holding a cup, at three difficulty levels (cup empty or full, at normal or fast speed). Half were instructed to focus internally (on their movements) and half externally (on the cup). The effects of focus, age, and difficulty level were tested for movement time, mean inclination of the cup, inclination variability, and smoothness with 2 × 2 × 3 ANOVAs. Significant effects of difficulty were consistent across variables (p  less then  0.05). An effect of focus was present only for the inclination variability of the stand-to-sit (p  less then  0.03), favoring an internal focus (less variability). The age × focus interaction was significant for mean cup inclination, but post hoc tests failed to reveal any significant differences. The results of this study, together with the literature, suggest that an external focus may not benefit the performance of young or older adults in general mobility activities of daily living. The prevalent assumption that an external focus is always beneficial for performance needs further empirical testing.Eye and hand movements are often made in isolation but for reaching movements they are usually coupled. Despite this, evidence for spatial coupling between the eye and hand effector is mixed and have usually been restricted to straight-line movements, while real-world hand movements have complex trajectories. Here, using a novel obstacle avoidance task where an obstacle appeared in an infrequent number of trials, we establish a stronger link between the saccade and hand trajectory during more naturalistic curved hand trajectories. https://www.selleckchem.com/products/ko143.html We illustrate that the hand trajectory was coupled to the end-point of the saccade which was executed just prior to the hand movement onset. Interestingly, while the saccade end-point was related to whether the hand trajectory followed a straight or a curved path, the y-component of saccade end-point was related to whether the hand took a path passing from over or below the obstacle. Further, we observed a relationship between saccade locations and hand sub-movements where the number and timing of saccades and number of hand velocity peaks were related. These results illustrate a robust spatiotemporal and kinematic coupling between saccades and complex hand movement trajectories suggesting a shared kinematic representation underlying eye-hand movements.Thirteen shooters and eleven non-shooters completed two-legged and single-legged stance on a force platform. The dynamics of the center of pressure trajectory was assessed using sample entropy, correlation dimension and entropic half-life. Additionally, the body sway was quantified as the elliptical area of the trajectory. The shooters had lower sample entropy and tended to have longer entropic half-life during the single-legged stance. Across the two tasks, the correlation dimension in the anterior-posterior direction and the body sway in both directions were lower in the shooters. This suggests that extensive training in quiet stance is associated with altered postural control, especially during challenging single-legged stance and to a lesser extend during two-legged stance.Despite the strong association between social support and positive health outcomes, little is understood about its role in women's reproductive decision making. Developing insight into how women perceive, mobilize, and experience social support is critical to understanding their lived experiences of reproductive decision making and to implementing appropriate supporting structures to help women realize their reproductive choices. In this study, emergent fit with existing inductive research on the phenomenon of reproductive support is discussed. The existing theory of "optimizing social support for the preservation of self" and its underpinning categorical framework is maintained, but the extant categorical themes were all nuanced, refined, replaced, or removed to better reflect the support phenomenon among a wider cohort of women. This article builds on the existing knowledge base by producing a substantive theory of "optimizing social support for the preservation of self" with wider applicability.Background We report a unique case of renal cholesterol crystal embolism (CCE) induced by carotid artery stenting that was successfully treated with evolocumab, a fully human monoclonal antibody against proprotein convertase subtilisin kexin type 9 (PCSK9).Case presentation A 77-year-old man with hypertension, hyperlipidemia, and chronic kidney disease was referred to our department for decreased estimated glomerular filtration rate (eGFR)-from 32.0 to 13.9 mL/min/1.73 m2-5 weeks after carotid artery stenting. Further examination revealed livedo reticularis in the bilateral toes and eosinophilia (723/μL). Skin biopsy from livedo reticularis tissue in the bilateral toes showed cholesterol clefts in the small arteries. The patient was therefore diagnosed with CCE. After 25 weeks' administration of evolocumab at a dose of 140 mg subcutaneously administered every 2 weeks, his eGFR had improved from 10.7 to 18.1 mL/min/1.73 m2.Conclusion Evolocumab may have a beneficial effect on renal involvement in patients with CCE.BACKGROUND High-flow nasal cannula (HFNC) oxygen therapy provides effective respiratory management in patients with hypoxemic respiratory failure. However, the efficacy and tolerability of HFNC for patients with acute exacerbation of interstitial lung disease (AE-ILD) have not been established. This study was performed to assess the efficacy and tolerability of HFNC for patients with AE-ILD and identify the early predictors of the outcome of HFNC treatment. METHODS We retrospectively reviewed the records of patients with AE-ILD who underwent HFNC. Overall survival, the success rate of HFNC treatment, adverse events, temporary interruption of treatment, discontinuation of treatment at the patient's request, and predictors of the outcome of HFNC treatment were evaluated. RESULTS A total of 66 patients were analyzed. Of these, 26 patients (39.4%) showed improved oxygenation and were successfully withdrawn from HFNC. The 30-day survival rate was 48.5%. No discontinuations at the patient's request were observed, and no serious adverse events occurred.

  • The present study investigated the time course of repetitive maximal isometric grip strength, depending on the arm position, laterality (dominant vs. non-dominant side), and climbing level. The intervention aimed to provide a feasible indicator of maximal strength-endurance in climbing. Seventeen recreational (climbing level (CL) 6.8 (SD 0.5) on the Union Internationale des Associations d'Alpinisme (UIAA) metric scale) and eleven ambitious (CL 8.7 (SD 0.6) UIAA metric scale) climbers (age 27 (8) years; BMI 21.6 (1.9) kg/m2; ape index (arm span divided by body height) 1.05 (0.18); training volume 2.2 (1.0) h/week). Participants completed maximal isometric handgrip strength (Fmax) tests in four positions (left and right hand beside the trunk as well as left and right hand above the shoulder) plus twelve repetitive work-relief cycles, lasting 4 and 1 s where isometric strength, heart rate, and perceived exertion were recorded. Fmax differed between groups in nearly all positions. A large side × position × time × group interaction was observed for repetitive isometric grip strength (p = 0.009, ηp2 = 0.71). However, subsequent post-hoc tests did not reveal a significant difference between groups during each testing position. Additional correlation analysis between asymmetry and CL showed an inverse relationship for ambitious climbers (r = -0.71). In conclusion, the degree of grip strength decline did not relevantly differentiate between ambitious and recreational climbers. Thus, the time course of handgrip strength seems to mainly rely on maximal grip strength during the first contraction.
    This case report describes whether a female civil servant who developed bilateral ulnar neuropathy can be classified as having an occupational disease.

    The Dutch six-step protocol for the assessment and prevention of occupational diseases is used.

    Based on the six-step protocol, we propose that pressure on the ulnar nerve in the elbow region precipitated the neuropathy for this employee while working prolonged periods in elbow flexion with a laptop.

    Despite the low incidence laptop use might be a risk factor for the occurrence of ulnar neuropathy due to prolonged pressure on the elbow. Employers and workers need to be educated about this disabling occupational injury due to laptop use and about protective work practices such as support for the upper arm and elbow. This seems especially relevant given the trend of more flexible workspaces inside and outside offices, and given the seemingly safe appearance of laptop use.

Specifically, we asked participants (n = 1010 Portuguese) to categorize a set of ingredients (e.g., glucose, aspartame) regarding their composition (i.e., intrinsic vs. added/free sugars) and origin (e.g., natural vs. artificial) and if they were aware of the WHO guidelines for sugar intake. Overall, despite using information about sugar frequently and considering attending to such information as very important to stay healthy, most participants were unaware of the WHO guidelines and revealed difficulties in the categorization task. Women, participants with a higher level of education, and those with children in the household reported higher use of sugar content information present in nutritional labels, higher perceived knowledge of nutritional guidelines, and higher hit rates in categorizing sugar sources. Almost one-fourth of the population exceeds the daily limit recommended by the WHO. Therefore, characterizing the knowledge of a Portuguese sample regarding sugar sources and sugar intake guidelines is particularly relevant, and our results emphasize the need to implement effective strategies to reduce sugar intake.The U.S. has merely 4% of the world population, but contains 25% of the world's COVID-19 cases. Since the COVID-19 outbreak in the U.S., Massachusetts has been leading other states in the total number of COVID-19 cases. Racial residential segregation is a fundamental cause of racial disparities in health. Moreover, disparities of access to health care have a large impact on COVID-19 cases. Thus, this study estimates racial segregation and disparities in testing site access and employs economic, demographic, and transportation variables at the city/town level in Massachusetts. Spatial regression models are applied to evaluate the relationships between COVID-19 incidence rate and related variables. This is the first study to apply spatial analysis methods across neighborhoods in the U.S. to examine the COVID-19 incidence rate. The findings are (1) Residential segregations of Hispanic and Non-Hispanic Black/African Americans have a significantly positive association with COVID-19 incidence rate, indicating the hl insights for policymakers to propose new strategies to contain the COVID-19 transmissions in Massachusetts.This paper endeavors to evaluate rapeseed samples obtained in the process of storage experiments with different humidity (12% and 16% seed moisture content) and temperature conditions (25 and 30 °C). The samples were characterized by different levels of contamination with filamentous fungi. In order to acquire graphic data, the analysis of the morphological structure of rapeseeds was carried out with the use of microscopy. The acquired database was prepared in order to build up training, validation, and test sets. The process of generating a neural model was based on Convolutional Neural Networks (CNN), Multi-Layer Perceptron Networks (MLPN), and Radial Basis Function Networks (RBFN). The classifiers that were compared were devised on the basis of the environments Tensorflow (deep learning) and Statistica (machine learning). As a result, it was possible to achieve the lowest classification error of 14% for the test set, 18% classification error for MLPN, and 21% classification error for RBFN, in the process of recognizing mold in rapeseed with the use of CNN.

  • ough the literature on collective rituals. As such, collective participation implies positive outcomes both individually and collectively, which are further reinforced through key psychological mechanisms, in line with a Durkheimian approach to collective rituals.
    Studies and meta-analyses found individual, meso and micro-social factors that are associated with individual well-being, as well as a positive socio-emotional climate or collective well-being.

    This article simultaneously studies and examines these factors of well-being.

    Well-Being is measured as a dependent variable at the individual and collective level, as well as the predictors, in three cross-sectional and one longitudinal studies. https://www.selleckchem.com/products/sri-011381.html Education and social intervention workers (
    = 1300,
    = 80) from Chile, Spain and Uruguay participate; a subsample of educators (
    = 1,
    = 37) from the south central Chile and from Chile, Uruguay and Spain (
    = 1149); workers from organizations in Latin America and Southern Europe, military cadets from Argentina (
    < 1000); and teams (
    = 14) from Spanish companies.

    Individual and collective well-being indicators were related, suggesting that the emotional climate as a context improves personal well-being. Individual factors (emotional creativity and opennell-being in organizations. Organizational leadership moderates the relationship between task orientation and collective well-being in military context.

    Individual and microsocial factors influence personal well-being. Meso level factors favorable to well-being through processes which reinforce social belonging, influence directly collective well-being and indirectly personal well-being. Leadership that reinforces participation and belonging play a central role for emotional climate. Stress and emotional climate playing an important pivotal role for psychological well-being.

However, little research has focused on exploring the factors that can mitigate this effect. Within this framework, the present study examined the mediating role of positive and negative affects in the relationship between ethnic and racial discrimination and psychological well-being in the migrant population. About 919 Colombians, first-generation migrants, residing in Chile (Arica, Antofagasta, and Santiago) were evaluated, of which 50.5% were women, and the participants' average age was 35 years (range 18-65 years). Krieger's discrimination questionnaires, Watson's Positive and Negative Affect Schedule (PANAS), and Ryff's Psychological Well-Being Scale were applied. The measurement models of each variable were estimated, and then the structural equation models were used. The results of the hypothesized multiple mediation model showed that the main mediator in the relationship between ethnic-racial discrimination and psychological well-being was positive affects over negative ones.The current paper addresses two methodological problems pertinent to the analysis of observer studies in non-verbal rapport and beyond. These problems concern (1) the production of standardized stimulus materials that allow for unbiased observer ratings and (2) the objective measurement of non-verbal behaviors to identify the dyadic patterns underlying the observer impressions. We suggest motion capture and character animation as possible solutions to these problems and exemplarily apply the novel methodology to the study of gender and cultural differences in non-verbal rapport. We compared a Western, individualistic culture with an egalitarian gender-role conception (Germany) and a collectivistic culture with a more traditional gender role conceptions (Middle East, Gulf States). Motion capture data were collected for five male and five female dyadic interactions in each culture. Character animations based on the motion capture data served as stimuli in the observation study. Female and male observers from bostituent of rapport.Children who live on the margins of society are disadvantaged in achieving their developmental potential because of the lack of a necessary stable environment and nurturing care. Many early prevention programs aim at mitigating such effects, but often the evaluation of their long-term effect is missing. The aim of the study presented here was to evaluate such long-term effects in two prevention programs for children-at-risk growing up in deprived social environments focusing on child attachment representation as the primary outcome as well as on self-reflective capacities of teachers taking care of these children. The latter was a key component for promoting resilient behavior in children. Five hundred and twenty-six children aged 36 to 60 months at risk due to immigration status, low family socio-economic status and child behavior were examined in a cluster-randomized study comparing two preventions, the psychodynamic, attachment-based holistic approach EARLY STEPS (ES) with the classroom based FAUSTLOS (FA) number of social risk factors and the increase of problematic social behavior strongly indicate that an increase in teachers' self-reflective capacities helps to change children's attachment patterns which thus strengthens the resilience of these children-at-risk [An ethical vote from LPPKJP 2009-02-25 was obtained and the trial registered; Clinical trial registration information The trial was registered 14.02.2012 (DRKS00003500; https//www.drks.de)].This article discusses how the Generic Model of Psychotherapy (Orlinsky and Howard, 1987) can help to organize the psychotherapy research and the knowledge in the field of psychotherapy for sexual and gender minority patients. The structure that this traditional model provides is a good foundation for research in this field, inasmuch as it stresses macrosocial aspects that determine the provision of psychotherapy and contextualize its outcomes. Each one of the main components offered by the Generic Model of Psychotherapy - Determinants, Processes, and Consequences - are specified for psychotherapy with LGBT patients and are illustrated with a selection of already existing research in the field of sexual minorities; they are also stress areas marked by knowledge gaps that require future developments.

    ough the literature on collective rituals. As such, collective participation implies positive outcomes both individually and collectively, which are further reinforced through key psychological mechanisms, in line with a Durkheimian approach to collective rituals. Studies and meta-analyses found individual, meso and micro-social factors that are associated with individual well-being, as well as a positive socio-emotional climate or collective well-being. This article simultaneously studies and examines these factors of well-being. Well-Being is measured as a dependent variable at the individual and collective level, as well as the predictors, in three cross-sectional and one longitudinal studies. https://www.selleckchem.com/products/sri-011381.html Education and social intervention workers ( = 1300, = 80) from Chile, Spain and Uruguay participate; a subsample of educators ( = 1, = 37) from the south central Chile and from Chile, Uruguay and Spain ( = 1149); workers from organizations in Latin America and Southern Europe, military cadets from Argentina ( < 1000); and teams ( = 14) from Spanish companies. Individual and collective well-being indicators were related, suggesting that the emotional climate as a context improves personal well-being. Individual factors (emotional creativity and opennell-being in organizations. Organizational leadership moderates the relationship between task orientation and collective well-being in military context. Individual and microsocial factors influence personal well-being. Meso level factors favorable to well-being through processes which reinforce social belonging, influence directly collective well-being and indirectly personal well-being. Leadership that reinforces participation and belonging play a central role for emotional climate. Stress and emotional climate playing an important pivotal role for psychological well-being.

However, little research has focused on exploring the factors that can mitigate this effect. Within this framework, the present study examined the mediating role of positive and negative affects in the relationship between ethnic and racial discrimination and psychological well-being in the migrant population. About 919 Colombians, first-generation migrants, residing in Chile (Arica, Antofagasta, and Santiago) were evaluated, of which 50.5% were women, and the participants' average age was 35 years (range 18-65 years). Krieger's discrimination questionnaires, Watson's Positive and Negative Affect Schedule (PANAS), and Ryff's Psychological Well-Being Scale were applied. The measurement models of each variable were estimated, and then the structural equation models were used. The results of the hypothesized multiple mediation model showed that the main mediator in the relationship between ethnic-racial discrimination and psychological well-being was positive affects over negative ones.The current paper addresses two methodological problems pertinent to the analysis of observer studies in non-verbal rapport and beyond. These problems concern (1) the production of standardized stimulus materials that allow for unbiased observer ratings and (2) the objective measurement of non-verbal behaviors to identify the dyadic patterns underlying the observer impressions. We suggest motion capture and character animation as possible solutions to these problems and exemplarily apply the novel methodology to the study of gender and cultural differences in non-verbal rapport. We compared a Western, individualistic culture with an egalitarian gender-role conception (Germany) and a collectivistic culture with a more traditional gender role conceptions (Middle East, Gulf States). Motion capture data were collected for five male and five female dyadic interactions in each culture. Character animations based on the motion capture data served as stimuli in the observation study. Female and male observers from bostituent of rapport.Children who live on the margins of society are disadvantaged in achieving their developmental potential because of the lack of a necessary stable environment and nurturing care. Many early prevention programs aim at mitigating such effects, but often the evaluation of their long-term effect is missing. The aim of the study presented here was to evaluate such long-term effects in two prevention programs for children-at-risk growing up in deprived social environments focusing on child attachment representation as the primary outcome as well as on self-reflective capacities of teachers taking care of these children.
