It is standard practice to model site-to-site variability of substitution rates by discretizing a continuous distribution into a small number, K, of equiprobable rate categories. We demonstrate that the variance of this discretized distribution has an upper bound determined solely by the choice of K and the mean of the distribution. This bound can introduce biases into statistical inference, especially when estimating parameters governing site-to-site variability of substitution rates. Applications to two large collections of sequence alignments demonstrate that this upper bound is often reached in analyses of real data. When parameter estimation is of primary interest, additional rate categories or more flexible modeling methods should be considered.The introduction of high-yielding semi-dwarf varieties of wheat into cultivation has led to a "green revolution." This has required intensive research into various sources of dwarfism in wheat. However, there has been very little advancement in research on dwarfing genes in rye in comparison to wheat or barley. So far, three dominant dwarfing genes (Ddw1, Ddw3, and Ddw4) and three recessive genes (ct1, ct2, and np) have been characterized and precisely mapped in rye. There is no complete catalog of dwarfing genes available in rye. This paper presents an identification of the source of dwarfism and preliminary characterization of the new recessive gene dw9 from the BK-1 line. The gene was mapped on the long arm of the 6R chromosome and belongs to the GA-insensitive group. The initial characterization of the influence of this gene on morphological traits shows that it significantly affects the decrease of yielding trait parameters. A full evaluation can be performed after detailed breeding studies.Wildlife monitoring using passive telemetry has become a robust method for investigating animal migration. With increased use, this method progressively pollutes the environment with technological waste represented by so called ghost tags (PIT tags ending in the environment due to reproductive expulsions, shedding or animal mortality). However, their presence in the environment may lead to failed detections of living individuals. We used tagging data from studies of the asp Leuciscus aspius and the bleak Alburnus alburnus collected from 2014 to 2018 and located ghost tag positions on the monitored spawning site using portable backpack reader for their detection. We modelled virtual river-wide flat-bed antennas (widths 0.2, 0.4, 0.6 and 0.8 m) representing monitoring effort and estimated the probability of the presence of ghost tags within the antenna field. Of 3724 PIT tags used in the study, we detected on the spawning ground 173 ghost tags originating from long-term monitoring. https://www.selleckchem.com/products/3-3-cgamp.html The ghost tags accumulated in the environment in time, suggesting insufficient degradation rate or shift downstream from the research site. Number of ghost tags present on the spawning ground led to high probability of disabled readings of tagged fish passing through the antenna electro-magnetic field. We demonstrate how accumulated ghost tags may cause detection failures for focal species and incomplete data acquisition. We infer that intensive long-term monitoring using PIT tag technology may encumber future data acquisition or entail additional costs for clean-up.While genome-wide association studies have identified genes involved in differential treatment responses to inhaled corticosteroids (ICS) in asthma, few studies have evaluated the potential effects of age in this context. A significant proportion of asthmatics experience exacerbations (hospitalizations and emergency department visits) during ICS treatment. We evaluated the interaction of genetic variation and age on ICS response (measured by the occurrence of exacerbations) through a genome-wide interaction study (GWIS) of 1,321 adult and child asthmatic patients of European ancestry. We identified 107 genome-wide suggestive (P less then 10-05) age-by-genotype interactions, two of which also met genome-wide significance (P less then 5x10-08) (rs34631960 [OR 2.3±1.6-3.3] in thrombospondin type 1 domain-containing protein 4 (THSD4) and rs2328386 [OR 0.5±0.3-0.7] in human immunodeficiency virus type I enhancer binding protein 2 (HIVEP2)) by joint analysis of GWIS results from discovery and replication populations. In addition to THSD4 and HIVEP2, age-by-genotype interactions also prioritized genes previously identified as asthma candidate genes, including DPP10, HDAC9, TBXAS1, FBXL7, and GSDMB/ORMDL3, as pharmacogenomic loci as well. This study is the first to link these genes to a pharmacogenetic trait for asthma.BACKGROUND Systematic collection of mortality/morbidity data over time is crucial for monitoring trends in population health, developing health policies, assessing the impact of health programs. In Poland, a comprehensive analysis describing trends in disease burden for major conditions has never been published. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) provides data on the burden of over 300 diseases in 195 countries since 1990. We used the GBD database to undertake an assessment of disease burden in Poland, evaluate changes in population health between 1990-2017, and compare Poland with other Central European (CE) countries. METHODS The results of GBD 2017 for 1990 and 2017 for Poland and CE were used to assess rates and trends in years of life lost (YLLs), years lived with disability (YLDs), disability-adjusted life years (DALYs). Data came from cause-of-death registration systems, population health surveys, disease registries, hospitalization databases, and the scientific literes, poses a challenge for the Polish health-care system. IHD is still the leading cause of disease burden in Poland, but DALYs from IHD are declining. To further reduce disease burden, an integrated response focused on NCDs and population groups with disproportionally high burden is needed.Exosomes are extracellular vesicles (EVs) of ~20-200 nm diameter that shuttle DNAs, RNAs, proteins and other biomolecules between cells. The large number of biomolecules present in exosomes demands the frequent use of high-throughput analysis. This, in turn, requires technical replicates (TRs), and biological replicates (BRs) to produce accurate results. As the number and abundance of identified biomolecules varies between replicates (Rs), establishing the replicate variability predicted for the event under study is essential in determining the number of Rs required. Although there have been few reports of replicate variability in high throughput biological data, none of them focused on exosomes. Herein, we determined the replicate variability in protein profiles found in exosomes released from 3 lung adenocarcinoma cell lines, H1993, A549 and H1975. Since exosome isolates are invariably contaminated by a small percentage of ~200-300 nm microvesicles, we refer to our samples as exosome-enriched EVs (EE-EVs). We generated BRs of EE-EVs from each cell line, and divided each group into 3 TRs.

However, multiple primary survivors were more likely to report severe limitations in physical function than the single primary (PR = 1.48 (95% CI, 1.28-1.71)) and no-cancer (PR = 1.64 (95% CI, 1.42-1.88)) groups. Using a cane or walker and balance difficulties were also significantly more common among multiple primary survivors. CONCLUSIONS Despite a similar prevalence of comorbid medical conditions, severe functional limitations were significantly more common among multiple primary survivors than single primary survivors or individuals without cancer. IMPLICATIONS FOR CANCER SURVIVORS Assessment of functional status and treatment of physical deficits may be an especially critical component of care for older patients with a history of multiple cancer diagnoses.PURPOSES Cancer-related distress is known to persist long after completion of treatment. Factors related to distress are largely unexplored in colorectal cancer (CRC) survivors. We examined changes over time and risk factors for distress in CRC patients over the first year after surgery. METHODS We included 212 CRC patients with data at 6 and 12 months post-surgery from the ColoCare Study in Heidelberg, Germany. Sociodemographic and lifestyle factors, social support, and health-related quality of life (HrQOL) prior to surgery were evaluated as predictors of cancer-related distress. Distress was measured with the Cancer and Treatment Distress instrument (CTXD). Linear regression analyses examined associations between risk factors and distress. RESULTS Distress subscale scores varied significantly over time health burden subscale score increased (P  less then  .001), while finances (P = .004), medical demands (P  less then  .001), and identity (P  less then  .001) subscale scores decreased over time. Uncertainty and family strain subscale scores did not change. Younger age, lower income, advanced tumor stage, poorer social support, and poorer baseline HrQOL predicted higher level distress at 6 and 12 months. CONCLUSION Cancer-related distress continues unresolved after surgery. Although some risk factors are difficult to alter, those at highest risk can be identified earlier for possible preventive strategies. IMPLICATIONS FOR CANCER SURVIVORS Screening for risk factors pre-surgery would allow for targeted interventions including strategies to improve resources for those with low support, thereby reducing long-term distress in CRC survivors.BACKGROUND Nicotine, the pharmacologically active substance in both tobacco and many electronic cigarette (e-cigarette) liquids, is responsible for the addiction that sustains cigarette smoking. With 8 million deaths worldwide annually, smoking remains one of the major causes of disability and premature death. However, nicotine also plays an important role in smoking cessation strategies. OBJECTIVES The aim of this study was to develop a comprehensive, whole-body, physiologically based pharmacokinetic/pharmacodynamic (PBPK/PD) model of nicotine and its major metabolite cotinine, covering various routes of nicotine administration, and to simulate nicotine brain tissue concentrations after the use of combustible cigarettes, e-cigarettes, nicotine gums, and nicotine patches. METHODS A parent-metabolite, PBPK/PD model of nicotine for a non-smoking and a smoking population was developed using 91 plasma and brain tissue concentration-time profiles and 11 heart rate profiles. Among others, cytochrome P450 (CYP) 2A6 nding of the recent increase in youth e-cigarette use.PURPOSE Early squamous cell neoplasia (ESCN) in the oesophagus is a highly treatable condition. Lesions confined to the mucosal layer can be curatively treated endoscopically. We build a computer-assisted detection system that can classify still images or video frames as normal or abnormal with high diagnostic accuracy. METHODS We present a new benchmark dataset containing 68K binary labelled frames extracted from 114 patient videos whose imaged areas have been resected and correlated to histopathology. Our novel convolutional network architecture solves the binary classification task and explains what features of the input domain drive the decision-making process of the network. RESULTS The proposed method achieved an average accuracy of 91.7% compared to the 94.7% achieved by a group of 12 senior clinicians. Our novel network architecture produces deeply supervised activation heatmaps that suggest the network is looking at intrapapillary capillary loop patterns when predicting abnormality. CONCLUSION We believe that this dataset and baseline method may serve as a reference for future benchmarks on both video frame classification and explainability in the context of ESCN detection. A future work path of high clinical relevance is the extension of the classification to ESCN types.Swelling of astrocytes represents a major component of the brain edema associated with many neurological conditions, including acute hepatic encephalopathy (AHE), traumatic brain injury (TBI) and ischemia. It has previously been reported that exposure of cultured astrocytes to ammonia (a factor strongly implicated in the pathogenesis of AHE), oxygen/glucose deprivation, or to direct mechanical trauma results in an increase in cell swelling. Since dietary polyphenols have been shown to exert a protective effect against cell injury, we examined whether resveratrol (RSV, 3,5,4'-trihydroxy-trans-stilbene, a stilbenoid phenol), has a protective effect on astrocyte swelling following its exposure to ammonia, oxygen-glucose deprivation (OGD), or trauma in vitro. Ammonia increased astrocyte swelling, and pre- or post-treatment of astrocytes with 10 and 25 µM RSV displayed an additive effect, while 5 µM did not prevent the effect of ammonia. However, pre-treatment of astrocytes with 25 µM RSV slightly, but significantsporter-1 (NKCC1), factors known to induce astrocytes swelling, when the cells were treated with ammonia or after trauma or ischemia. https://www.selleckchem.com/products/ABT-737.html Further, inhibition of ERK1/2, and p38MAPK diminished the RSV-induced exacerbation of cell swelling post-ammonia, trauma and OGD treatment. These findings strongly suggest that treatment of cultured astrocytes with RSV enhanced the ammonia, ischemia and trauma-induced cell swelling, likely through the exacerbation of intercellular signaling kinases and ion transporters. Accordingly, caution should be exercised when using RSV for the treatment of these neurological conditions, especially when brain edema is also suspected.

PURPOSE This study was performed to investigate the association between the use of pregabalin and injury. METHODS The study was based on a predefined cohort of patients aged ≥20 years who had been registered for ≥6 months and contributed to the Japan Medical Data Center claims database. All patients (cases) had been treated for injuries from January 2014 to December 2016. One-to-four case-control matching was performed for age, sex, calendar day of injury (index date), and follow-up duration. A conditional logistic regression analysis was performed to calculate the odds ratio (OR) for pregabalin use within 180 days prior to the index date between the matched cases and controls, with adjustment for comorbidities and relevant drug categories associated with a risk of injury. To minimize within-individual confounding, we also performed a case-crossover analysis to compare the odds of pregabalin use between a 30-day hazard period immediately before the injury and five consecutive 30-day control periods within individuals with injury. RESULTS Among the 2 324 974 people in the nested cohort, we identified 18 084 cases with injury and 71 885 matched controls. The proportion of pregabalin use was 1.7% (304/18 084) and 1.1% (803/71 885), respectively. The adjusted OR for injury was 1.22 (95% confidence interval [CI], 1.06-1.40). In the case-crossover analysis (n = 304), pregabalin use was also significantly associated with an increased risk of injury (adjusted OR, 1.48; 95% CI, 1.10-2.00). CONCLUSION This large database study using two different study designs consistently suggested that the use of pregabalin may be associated with an increased risk of injury. © 2020 John Wiley & Sons Ltd.PURPOSE Echo planar imaging is used widely for its imaging speed. However, its applications often suffer from ghost artifacts. In the community, an approach using three navigator echoes is used commonly for the artifact correction. Although this scheme is effective, as the matrix size increases for high-resolution imaging, the navigator echoes can contribute significantly to increasing the "required minimum TE." To overcome this issue, this work proposes the use of an alternative navigator echo scheme called the "TR-external" scheme. METHODS The TR-external scheme reduces the required minimum TE by allocating an  additional excitation loop for the navigator echoes before every main excitation loop. In this work, a detailed analysis on the TR-external scheme was performed to assess its performance in comparison to the standard scheme. Visual fMRI was performed to check the feasibility of using the TR-external scheme for detecting functional signals. RESULTS The performance of the TR-external scheme was comparable with that of the standard scheme in terms of the SNR, elimination of ghost artifacts, and the BOLD detection. For a given matrix size (288 × 288), the TR-external scheme allowed a substantially shorter TE (5.94 ms) compared with the standard scheme, which resulted in a higher SNR. https://www.selleckchem.com/products/AZD1480.html Furthermore, this feature enabled the submillimeter-resolution (0.73 × 0.73 mm2 ) fMRI measurement with a favorable TE (35 ms) at 3 T. The fMRI results revealed that activated voxels are well localized along the cortical ribbon. CONCLUSION A TR-external scheme for EPI phase correction was implemented at 3 T. Its feasibility for submillimeter-resolution fMRI was successfully demonstrated. © 2020 The Authors.

C57BL/6J mice were fed with HFD or standard diet (SD) for 1, 2, or 8 weeks. Colonic interleukin (IL)-1β, IL-6, and malondialdehyde (MDA) levels were measured. Expression of occludin in colonic tissues was examined by western blot. Substance P (SP), S100β, GFAP, and phosphorylated mitogen-activated protein kinase 1 (pERK) were assessed in whole mount specimens of colonic plexus by immunohistochemistry. Colonic tachykininergic contractions, elicited by electrical stimulation or exogenous SP, were recorded in the presence or absence of fluorocitrate (FC). To mimic exposure to HFD, cultured EGCs were incubated with palmitate (PA) and/or lipopolysaccharide (LPS). SP and IL-1β levels were assayed in the culture medium by ELISA. HFD mice displayed an increase in colonic IL-1β and MDA, and a reduction of occludin at week 2. These changes occurred to a greater extent at week 8. In vitro electrically evoked tachykininergic contractions were enhanced in HFD mice after 2 or 8 weeks, and they were blunted by FC. Colonic IL-6 levels as well as substance P and S100β density in myenteric ganglia of HFD mice were increased at week 8, but not at week 1 or 2. In cultured EGCs, co-incubation with palmitate plus LPS led to a significant increase in both SP and IL-1β release. HFD-induced obesity is characterized by a hyperactivation of EGCs and is involved in the development of enteric motor disorders through an increase in tachykininergic activity and release of pro-inflammatory mediators. © 2020 Federation of American Societies for Experimental Biology.PURPOSE The balanced steady-state free precession sequence has been previously explored to improve the efficient use of nonrecoverable hyperpolarized 13 C magnetization, but suffers from poor spectral selectivity and long acquisition time. The purpose of this study was to develop a novel metabolite-specific 3D bSSFP ("MS-3DSSFP") sequence with stack-of-spiral readouts for improved lactate imaging in hyperpolarized [ 1- 13 C ]pyruvate studies on a clinical 3T scanner. METHODS Simulations were performed to evaluate the spectral response of the MS-3DSSFP sequence. Thermal 13 C phantom experiments were performed to validate the MS-3DSSFP sequence. In vivo hyperpolarized [ 1- 13 C ], pyruvate studies were performed to compare the MS-3DSSFP sequence with metabolite-specific gradient echo ("MS-GRE") sequences for lactate imaging. RESULTS Simulations, phantom, and in vivo studies demonstrate that the MS-3DSSFP sequence achieved spectrally selective excitation on lactate while minimally perturbing other metabolites. Compared with MS-GRE sequences, the MS-3DSSFP sequence showed approximately a 2.

Chronic rejection is the major leading cause of morbidity and mortality after lung transplantation. Bronchiolitis obliterans syndrome (BOS), a fibroproliferative disorder of the small airways, is the main manifestation of chronic lung allograft rejection. We investigated, using transgenic mice, the mechanisms through which the deficiency of IL-1β/IL-18, Casp-1, or Fpr-1 genes could be protective in an experimental model of BOS, induced in mice by allogeneic heterotopic tracheal transplantation. https://www.selleckchem.com/products/PHA-665752.html Fpr-1 KO mice showed a marked reduction in histological markers of BOS and of mast cell numbers compared to other groups. Molecular analyses indicated that the absence of the Fpr-1 gene was able to decrease NF-κB nuclear translocation and modulate NLRP3 inflammasome signaling and the mitogen-activated protein kinase (MAPK) pathway in a more significant way compared to other groups. Additionally, Fpr-1 gene deletion caused a reduction in resistance to the apoptosis, assessed by the TUNEL assay. Immunohistochemical analyses indicated changes in nitrotyrosine, PARP, VEGF, and TGF-β expression associated with the pathology, which were reduced in the absence of the Fpr1 gene more so than by the deletion of IL-1β/IL-18 and Casp-1. We underline the importance of the NLRP3 inflammasome and the pathogenic role of Fpr-1 in experimental models of BOS, which is the result of the modulation of immune cell recruitment together with the modulation of local cellular activation, suggesting this gene as a new target in the control of the pathologic features of BOS.The nucleolus is the site of ribosome biogenesis and has been recently described as important sensor for a variety of cellular stressors. In the last two decades, it has been largely demonstrated that many chemotherapeutics act by inhibiting early or late rRNA processing steps with consequent alteration of ribosome biogenesis and activation of nucleolar stress response. The overall result is cell cycle arrest and/or apoptotic cell death of cancer cells. Our previously data demonstrated that ribosomal protein uL3 is a key sensor of nucleolar stress activated by common chemotherapeutic agents in cancer cells lacking p53. We have also demonstrated that uL3 status is associated to chemoresistance; down-regulation of uL3 makes some chemotherapeutic drugs ineffective. Here, we demonstrate that in colon cancer cells, the uL3 status affects rRNA synthesis and processing with consequent activation of uL3-mediated nucleolar stress pathway. Transcriptome analysis of HCT 116p53-/- cells expressing uL3 and of a cell sub line stably depleted of uL3 treated with Actinomycin D suggests a new extra-ribosomal role of uL3 in the regulation of autophagic process. By using confocal microscopy and Western blotting experiments, we demonstrated that uL3 acts as inhibitory factor of autophagic process; the absence of uL3 is associated to increase of autophagic flux and to chemoresistance. Furthermore, experiments conducted in presence of chloroquine, a known inhibitor of autophagy, indicate a role of uL3 in chloroquine-mediated inhibition of autophagy. On the basis of these results and our previous findings, we hypothesize that the absence of uL3 in cancer cells might inhibit cancer cell response to drug treatment through the activation of cytoprotective autophagy. The restoration of uL3 could enhance the activity of many drugs thanks to its pro-apoptotic and anti-autophagic activity.The present study aimed to examine associations between body image and under-reporting in female Japanese university students enrolled in a nutrition degree program. A total of 100 participants (aged 18-29 years) completed (1) a self-administered questionnaire including the Ben-Tovim Walker Body Attitudes Questionnaire (BAQ), (2) a dietary assessment using a brief-type self-administered diet history questionnaire (BDHQ), (3) a physical activity assessment using Bouchard's Physical Activity Record (BAR) and a tri-axial accelerometer, (4) detailed anthropometry, and (5) body composition assessment. Based on the energy intake to basal metabolic rate ratio (EIBMR) and using a cut-off point of 1.35, 67% of participants were considered under-reporters (URs). While there was no between-group difference in BMI, URs had significantly (p less then 0.05) greater percentage body fat (%BF) and trunk fat (%TF) compared with non-URs. Regression analyses indicated accuracy of body perception and a discrepancy between current and ideal weight were associated with EIBMR, whereas the salience subscale of the BAQ was associated with reported EI. The study raises concerns regarding the validity of EI reported from young Japanese females as they are known to have a strong preoccupation with thinness, even with an acceptable BMI and health and nutritional knowledge.The development of monoclonal antibodies (mAbs) has provided vast opportunities to treat a wide range of diseases from cancer to viral infections. While plant-based production of mAbs has effectively lowered the upstream cost of mAb production compared to mammalian cell cultures, further optimization of downstream processing, especially in extending the longevity of Protein A resin by an effective bulk separation step, will further reduce the overall prohibitive cost of mAb production. In this study, we explored the feasibility of using aqueous two-phase separation (ATPS) in capturing and separating plant-made mAbs from host proteins. Our results demonstrated that an anti-West Nile virus mAb (E16) was efficiently separated from most plant host proteins by a single ATPS step, comprising the mixing of plant extracts containing Hydrophobin-Protein A fusion protein (HPA) and E16 and the subsequent incubation with an inexpensive detergent. This simple ATPS step yielded a highly enriched E16 mAb preparation with a recovery rate comparable to that of Protein A chromatography. The ATPS-enriched E16 retained its structural integrity and was fully functional in binding its target antigen. Notably, HPA-based ATPS was also effective in enriching E16 from plant host proteins when both HPA and E16 were produced in the same leaves, supporting the potential of further streamlining the downstream purification process. Thus, ATPS based on plant-produced HPA in unpurified extract is a cost-effective yet efficient initial capture step for purifying plant-made mAbs, which may significantly impact the approach of mAb purification.

RESULTS Of the 85,972 encounters with 465 physicians, 11% resulted in a corticosteroid. The median physician prescribing rate was 4.0% (range less then 1% to 81%). Corticosteroid receipt was associated with higher satisfaction versus receiving nothing (OR2.54; 95%CI2.25-2.87). Patients who received both an antibiotic and a corticosteroid reported the highest satisfaction (OR 3.91; 95%CI3.27-4.68). There was no correlation between individual physicians' corticosteroid and antibiotic prescribing rates. CONCLUSIONS Corticosteroid receipt was associated with patient satisfaction. Most physicians rarely prescribed corticosteroids, yet a small number prescribed them frequently. Identification of high prescribing physicians for educational interventions could reduce use of corticosteroids for acute respiratory tract infections. The authors had access to all data and were involved in all aspects of this Clinical Communication to the Editor's preparation. They have no conflicts of interest to disclose and received no financial support in the preparation of this manuscript. CONTEXT Patients who have suffered from persistent symptoms often undergo lumbar spinal surgery (LSS). Motor imagery should be added to postoperative home exercises to reduce patient complaints. OBJECTIVE The aim of this study was to compare the effects of home exercise plus motor imagery and only home exercise in patients undergoing LSS. DESIGN A randomized controlled study. SETTINGS This study was designed by researchers at Dokuz Eylul University. PARTICIPANTS Thirty-seven patients undergoing LSS were randomized to motor imagery group (n = 19) and control group (n = 18). MAIN OUTCOME MEASURES Pain was measured by Visual Analogue Scale, disability related to low back pain by Oswestry Disability Index, pain-related fear by Tampa Scale of Kinesiophobia, depression by Beck Depression Inventory, quality of life by World Health Organization Quality of Life Scale-Short Form (WHOQOL-BREF). All assessments were repeated in the preoperative period, three weeks after and six weeks after the surgery. INTERVENTIONS Motor imagery group underwent home exercise plus motor imagery program applied by voice recording. Control group underwent only home exercise program. Exercise program compliance was monitored by exercise diary and telephone calls once every week. RESULTS There was a significant improvement in pain at rest and during activity, disability, kinesiophobia, depression, physical health and psychological sub-parameters of WHOQOL-BREF between preoperative period, and the third week and sixth week in both groups (p  less then  0.05). When comparing groups for gain scores, there was a more significant improvement in pain during activity in motor imagery group (p  less then  0.05). Motor imagery should be addressed as an effective treatment after LSS. INTRODUCTION Disease-related malnutrition (DRM) is underdiagnosed and underreported despite its well-known association with a worse prognosis. The emergence of Big Data and the application of artificial intelligence in Medicine have revolutionized the way knowledge is generated. The aim of this study is to assess whether a Big Data tool could help us detect the amount of DRM in our hospital. METHODOLOGY This was a descriptive, retrospective study using the Savana Manager® tool, which allows for automatically analyzing and extracting the relevant clinical information contained in the free text of the electronic medical record. A search was performed using the term "malnutrition", comparing the characteristics of patients with DRM to the population of hospitalized patients between January 2012 and December 2017. RESULTS Among the 180,279 hospitalization records with a discharge report in that period, only 4,446 episodes (2.47%) included the diagnosis of malnutrition. The mean age of patients with DRM was 75 years (SD 16), as compared to 59 years (SD 25) for the overall population. There were no sex differences (51% male). In-hospital death occurred in 7.08% of patients with DRM and 2.98% in the overall group. Mean stay was longer in patients with DRM (8 vs. 5 days, P less then .0001) and there were no significant differences in the 72-hour readmission rate. The most common diagnoses associated with DRM were heart failure (35%), respiratory infection (23%), urinary infection (20%), and chronic kidney disease (15%). CONCLUSION Underdiagnosis of DRM remains a problem. Savana Manager® helps us to better understand the profile of these patients. L.U.In silico cancer models have demonstrated great potential as a tool to improve drug design, optimise the delivery of drugs to target sites in the host tissue and, hence, improve therapeutic efficacy and patient outcome. However, there are significant barriers to the successful translation of in silico technology from bench to bedside. More precisely, the specification of unknown model parameters, the necessity for models to adequately reflect in vivo conditions, and the limited amount of pertinent validation data to evaluate models' accuracy and assess their reliability, pose major obstacles in the path towards their clinical translation. This review aims to capture the state-of-the-art in in silico cancer modelling of vascularised solid tumour growth, and identify the important advances and barriers to success of these models in clinical oncology. Particular emphasis has been put on continuum-based models of cancer since they - amongst the class of mechanistic spatio-temporal modelling approaches - are well-established in simulating transport phenomena and the biomechanics of tissues, and have demonstrated potential for clinical translation. https://www.selleckchem.com/products/AZ-960.html Three important avenues in in silico modelling are considered in this contribution first, since systemic therapy is a major cancer treatment approach, we start with an overview of the tumour perfusion and angiogenesis in silico models. Next, we present the state-of-the-art in silico work encompassing the delivery of chemotherapeutic agents to cancer nanomedicines through the bloodstream, and then review continuum-based modelling approaches that demonstrate great promise for successful clinical translation. We conclude with a discussion of what we view to be the key challenges and opportunities for in silico modelling in personalised and precision medicine.

Addressing the social stigma of mental illness is of importance in Iraq where mentally ill patients experience the compounded disadvantages of inadequate health services and illness stigma. To study the prevalence and magnitude of the social stigma towards mental illnesses. A cross-sectional study has been carried out on 300 male and female participants at shopping malls and public cafes in Baghdad, Iraq. A self-administered questionnaire made data collection. Descriptive, and analytic statics procedure was operated as far as a convenience by using Excel 365 version as a data management tool. About (80%) of the respondents revealed a moderate degree of stigmatising attitude towards mental illness with a Likert scale total equivalent score range of (2.34-3.669). About (20%) of respondents showed a low degree of stigmatising attitude towards mental illness, with a Likert scale total equivalent score range of (1-2.339). -value was highly significant (=0.011798) <0.05 among gender variables while it is not significant among age, income, education, and positive family of mental illnesses. 83% of the respondents prefer the medical management of mental illnesses. There were no clear roles of socio-demographic factors in the stigmatic attitude towards mental illnesses. This finding warrants a more in-depth look into the Iraqi community's cultural, social, and moral contexts.

The present study examined the role of risk taking and inhibitory control, key cognitive processes believed to govern behavioral regulation, as mechanisms that underlie the association between childhood maltreatment and the early stages of alcohol use. A sample of 129 maltreated adolescents and 102 socioeconomic status-matched, nonmaltreated adolescents and their parents completed three annual assessments, including computer-administered tasks and adolescent- and parent-report questionnaires, across ages 12-13 through 14-15 years. Childhood maltreatment was not directly associated with alcohol use in middle adolescence but was significantly associated with deficits in inhibitory control in early adolescence, which, in turn, led to significantly increased alcohol use in middle adolescence. Indeed, decreased inhibitory control was significant as a mediator, highlighting the salient role of this cognitive process in the early stages of alcohol use among maltreated adolescents. Neurocognitive impairment is considered a core feature of mood disorders. Research has shown that neurocognitive impairment often persists beyond mood symptom resolution and can have significant deleterious effects on interpersonal relationships, academic achievement, occupational functioning and independent living. As such, neurocognitive impairment has become an important target for intervention. In this systematic review, we aimed to examine the extant literature to ascertain whether current standard evidence-based psychotherapies can improve neurocognitive functioning in mood disorders. Studies examining changes in neurocognitive functioning following evidence-based psychotherapy were identified using MEDLINE, PsycINFO and Web of Science databases. Given the heterogeneity of study procedures, treatment protocols and patient samples, a narrative rather than meta-analytic review technique was employed. Nineteen studies (21 articles) met inclusion criteria. There was preliminary evidence of improved executive functioning following evidence-based psychotherapy for Major Depressive Disorder and Bipolar Disorder. There was also some signal of reduced negative biases in emotional information processing following psychotherapy in depression. Due to methodological variability across studies however, it was difficult to draw clear conclusions. Findings from the current review suggest that evidence-based psychotherapies may influence some aspects of neurocognitive functioning in mood disorders. This continues to be an ongoing area of importance and warrants further research.

Fasciotomy to treat or prevent compartment syndromes in patients with truncal or peripheral arterial injuries is a valuable adjunct. The objective of this study was to document the current incidence, indications, and outcomes of below knee fasciotomy in patients with femoropopliteal arterial injuries. The PROspective Observational Vascular Injury Treatment registry of the American Association for the Surgery of Trauma was utilized to identify patients undergoing two-incision four-compartment fasciotomy of the leg after repair of a femoropopliteal arterial injury. Outcomes after therapeutic versus prophylactic (surgeon label) fasciotomy were compared as was the technique of closure, that is, primary skin closure or application of a split-thickness skin graft (STSG). From 2013 to 2018, fasciotomy was performed in 158 patients overall, including 95.6% (151/158) at the initial operation. In the group of 139 patients who survived to discharge, fasciotomies were labeled as therapeutic in 58.3% (81/139) and prophylactic in 41.7% (58/139). There were no significant differences between the therapeutic and prophylactic groups in amputation rates (14.8% vs. 8.6%, = .919). https://www.selleckchem.com/products/finerenone.html Primary skin closure was achieved at a median of 5.0 days vs. 11.0days for STSG ( = .001). Over 55% of patients undergoing repair of an injury to a femoral or popliteal artery have a fasciotomy performed at the same operation. A "therapeutic" indication for fasciotomy continues to be more common than "prophylactic," while outcomes are identical in both groups.

Even in the era of intravitreal injection therapy (intravitreal operative injection of medication, IVOM) for the treatment of macular and retinal diseases, such as age-related macular degeneration (AMD), proliferative diabetic retinopathy (DR) and diabetic macular edema (DME) as well as proliferative stages and/or macular edema due to retinal vein occlusion (RVO), conventional retinal laser treatment is still of importance. It can be focally performed on an on-label basis for DME and macular edema due to branch RVO (BRVO) and its use as panretinal treatment for proliferative stages in retinal diseases as well as for the treatment of retinal holes is undisputed. The spectrum is extended by the treatment of less common diseases, such as retinal hemangioblastoma, macroaneurysms and subhyaloid macular hemorrhage. There is cause for concern that knowledge about the correct performance of retinal laser application might be shifted into the background due to an increase of IVOM treatment, which could lead to an increase in unnecessary errors. The aim of this manuscript is to increase awareness for the correct indications and execution of retinal laser treatment based on case examples of flawed or insufficient treatment.BACKGROUND With advances in surgical technique and instrumentation, intracorporeal anastomosis is increasingly being performed for laparoscopic total gastrectomy (LTG). However, the benefits of intracorporeal anastomosis in reducing postoperative complications have not been demonstrated, although its technical feasibility has been proven in many studies. In this study, we investigated the impact of intracorporeal anastomosis in reducing postoperative complications after LTG. METHODS We analyzed 410 consecutive gastric cancer patients who underwent LTG between 2008 and 2018. Of these, 118 underwent intracorporeal anastomosis using linear staplers (overlap method), while 292 underwent extracorporeal anastomosis using a circular stapler. Short-term surgical outcomes including postoperative complications were compared between the two groups. RESULTS The two groups showed no significant differences in age, sex, comorbidity, and abdominal surgery history. D2 lymph node dissection was more frequently performed in the intracorporeal group because of the presence of more advanced cancer stages. The overall morbidity in the intracorporeal and extracorporeal group was 23.7% and 27.7%, respectively (p = 0.405). However, the intracorporeal group showed a significantly lower incidence of late complications (0.8% vs. 7.5%, p = 0.008). Concerning complications, the incidence of anastomotic bleeding (0% vs. 5.5%, p = 0.008) and anastomotic stenosis (0% vs. 4.5%, p = 0.024) was significantly lower in the intracorporeal group. https://www.selleckchem.com/products/finerenone.html In univariate and multivariate analyses, American Society of Anesthesiologists score and operative bleeding were independent predictive factors for postoperative complications in patients who underwent intracorporeal anastomosis. CONCLUSIONS Intracorporeal anastomosis using linear staplers reduced anastomotic bleeding and stenosis compared to extracorporeal anastomosis after LTG. Future research will be required to determine the ideal method for intracorporeal anastomosis in LTG.PURPOSE Fatigue is a common problem among rectal cancer patients and can affect their quality of life. This study conducted a systematic review to better understand changes in fatigue severity in rectal cancer patients before, during, and after they undergo therapy. METHODS We used preset keywords to search the Cochrane Library, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), PubMed, and ProQuest databases for relevant studies published between 2000 and 2018, and data analysis was performed using Comprehensive Meta-Analysis (CMA) software (version 2.2.048) and SPSS software (version 19.0). In total, nine articles with complete data were included in our meta-analysis. RESULTS Fatigue conditions were compared before the start of therapy (baseline) and at 1 month (time 1), 3 months (time 2), 6 months (time 3), and 12 months (time 4) after the start of therapy. The standardized mean differences (SMDs) of the pooling effects size were 1.013 (95% confidence interval (CI) 0.217-1.810), - 0.551 (95% CI - 0.647 to - 0.456), - 0.330 (95% CI - 0.427 to - 0.233), and - 0.149 (95% CI - 0.221 to - 0.078), respectively. Subsequent analysis with a linear mixed effect model revealed that the estimate of the time variable was - 0.226 (p = 0.047), which indicates that the severity of fatigue varies over time and over the course of treatment. The results reveal that fatigue affects rectal cancer patients even before they start therapy. CONCLUSION Although fatigue worsened during the first month after cancer therapy, it gradually improved thereafter.PURPOSE Trastuzumab-based chemotherapy is usually administered through either a peripherally inserted central catheter (PICC) or a totally implanted vascular access device (PORT). As the most effective type of access is unknown, a feasibility trial, prior to conducting a large pragmatic trial, was undertaken. METHODS The trial methodology utilized the integrated consent model incorporating oral consent. Patients receiving trastuzumab-based neo/adjuvant chemotherapy for early-stage breast cancer were randomized to a PICC or PORT insertion. Feasibility was reflected through a combination of endpoints; however, the a priori definition of feasibility was > 25% of patients approached agreed to randomization and > 25% of physicians approached patients. Secondary outcomes included rates of line-associated complications such as thrombotic events requiring anticoagulation, line infections or phlebitis. RESULTS During the study period, 4/15 (26.7%) medical oncologists approached patients about study participation. Of 59 patients approached, 56 (94.9%) agreed to randomization, 29 (51.8%) were randomized to PICC and 27 (48.2%) to PORT access. Overall, 17.2% (5/29) and 14.8% (4/27) of patients had at least one line-associated complication in the PICC and PORT arms respectively. The study was terminated early due to slow accrual. CONCLUSION The study met its feasibility endpoints with respect to patient and physician engagement. However, the slow rate of accrual (56 patients in 2 years) means that conducting a large pragmatic trial would require additional strategies to make such a study possible.

BACKGROUND Atherosclerosis is a chronic inflammatory disease. Although Toll-like receptor 4 (TLR4) has been involved in inflammatory atherosclerosis, the exact mechanisms by which oxidized-low-density lipoproteins (ox-LDL) activates TLR4 and elicits inflammatory genesis are not fully known. Myeloid differentiation factor 2 (MD2) is an extracellular molecule indispensable for lipopolysaccharide recognition of TLR4. METHOD Apoe-/-Md2-/- mice and pharmacological inhibitor of MD2 were used in this study. We also reconstituted Apoe-/- mice with either Apoe-/- or Apoe-/-Md2-/- marrow-derived cells. Mechanistic studies were performed in primary macrophages, HEK-293T cells, and cell-free system. FINDING MD2 levels are elevated in atherosclerotic lesion macrophages, and MD2 deficiency or pharmacological inhibition in mice reduces the inflammation and stunts the development of atherosclerotic lesions in Apoe-/- mice fed with high-fat diet. Transfer of marrow-derived cells from Apoe-Md2 double knockout mice to Apoe knockout mice confirmed the critical role of bone marrow-derived MD2 in inflammatory factor induction and atherosclerosis development. Mechanistically, we show that MD2 does not alter ox-LDL uptake by macrophages but is required for TLR4 activation and inflammation via directly binding to ox-LDL, which triggers MD2/TLR4 complex formation and TLR4-MyD88-NFκB pro-inflammatory cascade. INTERPRETATION We provide a mechanistic basis of ox-LDL-induced macrophage inflammation, illustrate the role of macrophage-derived MD2 in atherosclerosis, and support the therapeutic potential of MD2 targeting in atherosclerosis-driven cardiovascular diseases. FUNDING This work was supported by the National Key Research Project of China (2017YFA0506000), National Natural Science Foundation of China (21961142009, 81930108, 81670244, and 81700402), and Natural Science Foundation of Zhejiang Province (LY19H020004). BACKGROUND Chromosomal instability plays an important part in cancer, but its genetic basis in liver tumorigenesis remains largely unclear. We aimed to characterize the mechanistic significance and clinical implication of mitotic regulator microtubule-associated protein 9 (MAP9) in hepatocellular carcinoma (HCC). METHODS The biological functions of MAP9 were determined by in vitro tumorigenicity assays. Systematic MAP9 knockout mouse (MAP9∆/∆) and hepatocyte-specific MAP9 knockout mouse (MAP9∆/∆hep) were generated to confirm the role of MAP9 in HCC. The clinical impact of MAP9 was assessed in primary HCC tissue samples. FINDINGS We found that MAP9 was frequently silenced in HCC tissue samples. The transcriptional silence of MAP9 in liver cancer cell lines and tissue samples was mediated by its promoter hypermethylation. MAP9 promoter hypermethylation or downregulation was associated with poor survival and recurrence in patients with HCC. Mechanistically, ectopic expression of MAP9 in LO2 and HepG2 cell lines impaired cell proliferation, colony formation, migration and invasion, and induced cell apoptosis and cycle arrest, whereas knockdown of MAP9 in Miha cell line showed the opposite effects. We found that MAP9∆/∆ mice spontaneously developed a liver hyperplastic nodule and MAP9∆/∆hep accelerated diethylnitrosamine-induced HCC formation. The tumour suppressive effect of MAP9 in HCC was mediated by downregulating excision repair cross-complementation group 3 (ERCC3), a nucleotide excision repair gene. Restoration of ERCC3 expression possessed an oncogenic potency and abrogated the tumour suppressive effects of MAP9. INTERPRETATION MAP9 is a novel tumour suppressor in HCC by inhibiting ERCC3 expression, and serves as a prognostic factor in HCC patients. https://www.selleckchem.com/products/fezolinetant.html BACKGROUND Osteosarcoma (OS) is the most common primary malignant bone tumour. Unfortunately, no new treatments are approved and over the last 30 years the survival rate remains only 30% at 5 years for poor responders justifying an urgent need of new therapies. The Mutt homolog 1 (MTH1) enzyme prevents incorporation of oxidized nucleotides into DNA and recently developed MTH1 inhibitors may offer therapeutic potential as MTH1 is overexpressed in various cancers. METHODS The aim of this study was to evaluate the therapeutic benefits of targeting MTH1 with two chemical inhibitors, TH588 and TH1579 on human osteosarcoma cells. Preclinical efficacy of TH1579 was assessed in human osteosarcoma xenograft model on tumour growth and development of pulmonary metastases. FINDINGS MTH1 is overexpressed in OS patients and tumour cell lines, compared to mesenchymal stem cells. In vitro, chemical inhibition of MTH1 by TH588 and TH1579 decreases OS cells viability, impairs their cell cycle and increases apoptosis in OS cells. TH1579 was confirmed to bind MTH1 by CETSA in OS model. Moreover, 90 mg/kg of TH1579 reduces in vivo tumour growth by 80.5% compared to non-treated group at day 48. This result was associated with the increase in 8-oxo-dG integration into tumour cells DNA and the increase of apoptosis. Additionally, TH1579 also reduces the number of pulmonary metastases. INTERPRETATION All these results strongly provide a pre-clinical proof-of-principle that TH1579 could be a therapeutic option for patients with osteosarcoma. FUNDING This study was supported by La Ligue Contre le Cancer, la SFCE and Enfants Cancers Santé. This contribution demonstrates experimentally how a series of annular dark-field transmission images collected in a scanning electron microscope (SEM) with a basic solid-state detector can be used to quantify electron scattering distributions (i.e., diffraction patterns). The technique is demonstrated at different primary electron energies with a polycrystalline aluminum sample and two amorphous samples comprising vastly different mass-thicknesses. Contrast reversal is demonstrated in both amorphous samples, suggesting that intuitive image contrast interpretation is not always straightforward even for ultrathin, low atomic number samples. We briefly address how the scattering distributions obtained here can be used as an aid to interpret contrast in annular dark-field images, and how to set up imaging conditions to obtain intuitively interpretable contrast from samples with regions of significantly different thickness.

The results demonstrate that the SSSLPS is an accurate, robust positioning system that is noise tolerant and can used for quadcopter operation even within a small greenhouse.Already in ancient times, semisolid preparations for cutaneous application, popularly known as ointments, played an important role in human society [...].Deep eutectic solvents (DESs) are newly introduced green solvents that have attracted much attention regarding fundamentals and applications. Of the problems along the way of replacing a common solvent by a DES, is the lack of information on the thermophysical properties of DESs. This is even more accentuated by considering the dramatically growing number of DESs, being made by the combination of vast numbers of the constituting substances, and at their various molar ratios. The speed of sound is among the properties that can be used to estimate other important thermodynamic properties. In this work, a global and accurate model is proposed and used to estimate the speed of sound in 39 different DESs. This is the first general speed of sound model for DESs. The model does not require any thermodynamic properties other than the critical properties of the DESs, which are themselves calculated by group contribution methods, and in doing so, make the proposed method entirely independent of any experimental data as input. The results indicated that the average absolute relative deviation percentages (AARD%) of this model for 420 experimental data is only 5.4%. Accordingly, based on the achieved results, the proposed model can be used to predict the speeds of sound of DESs.The current research work presents a first attempt to investigate the welding attributes of Elium® thermoplastic resin and the fusion bonding using ultrafast ultrasonic welding technique. The integrated energy director (ED) polymer-matrix composites (PMCs) panel manufacturing was carried out using the Resin Transfer Moulding (RTM) technique and the scheme is deduced to manufacture a bubble-free panel. Integrated ED configurations and flat specimens with Elium® film of different thickness at the interface were investigated for ultrasonic welding optimization. Optimised weld time for integrated ED and flat Elium® panels with film (0.5 mm thick) configuration was found to be 1 s and 5.5 s, respectively. https://www.selleckchem.com/products/cilengitide-emd-121974-nsc-707544.html The ED integrated configuration showed the best welding results with a lap shear strength of 18.68 MPa. The morphological assessment has shown significant plastic deformation of Elium® resin and the shear cusps formation, which enhances the welding strength. This research has the potential to open up an excellent and automated way of joining Elium® composite parts in automotive, wind turbines, sports, and many other industrial applications.Hair loss is a common medical problem affecting both males and females. Dermal papilla (DP) cells are the ultimate reservoir of cells with the potential of hair regeneration in hair loss patients. Here, we analyzed the role of macrophage-derived Wnts (3a and 7b) and macrophage extracellular vesicles (MAC-EVs) in promoting hair growth. We studied the proliferation, migration, and expression of growth factors of human-DP cells in the presence or absence of MAC-EVs. Additionally, we tested the effect of MAC-EV treatment on hair growth in a mouse model and human hair follicles. Data from western blot and flow cytometry showed that MAC-EVs were enriched with Wnt3a and Wnt7b, and more than 95% were associated with their membrane. The results suggest that Wnt proteins in MAC-EVs activate the Wnt/β-catenin signaling pathways, which leads to activation of transcription factors (Axin2 and Lef1). The MAC-EVs significantly enhanced the proliferation, migration, and levels of hair-inductive markers of DP cells. Additionally, MAC-EVs phosphorylated AKT and increased the levels of the survival protein Bcl-2. The DP cells treated with MAC-EVs showed increased expression of vascular endothelial growth factor (VEGF) and keratinocyte growth factor (KGF). Treatment of Balb/c mice with MAC-EVs promoted hair follicle (HF) growth in vivo and also increased hair shaft size in a short period in human HFs. Our findings suggest that MAC-EV treatment could be clinically used as a promising novel anagen inducer in the treatment of hair loss.Cisplatin (cis-diamminedichloroplatinum II [CDDP] ) is a well-known chemotherapeutic drug that has been used for the treatment of various types of human cancers, including head and neck cancer. Cisplatin exerts anticancer effects by causing DNA damage, replication defects, transcriptional inhibition, cell cycle arrest, and the induction of apoptosis. However, drug resistance is one of the most serious problems with cancer chemotherapy, and it causes expected therapeutic effects to not always be achieved. Here, we analyzed global microRNA (miRNA) expression in CD44 standard form (CD44s)-expressing SAS cells, and we identified miR-629-3p as being responsible for acquiring anticancer drug resistance in head and neck cancer. The introduction of miR-629-3p expression inhibited apoptotic cell death under cisplatin treatment conditions, and it promoted cell migration. Among the computationally predicted target genes of miR-629-3p, we found that a number of gene expressions were suppressed by the transfection with miR-629-3p. Using a xenografting model, we showed that miR-629-3p conferred cisplatin resistance to SAS cells. Clinically, increased miR-629-3p expression tended to be associated with decreased survival in head and neck cancer patients. In conclusion, our data suggest that the increased expression of miR-629-3p provides a mechanism of cisplatin resistance in head and neck cancer and may serve as a therapeutic target to reverse chemotherapy resistance.Nanobiotechnology has grown rapidly and become an integral part of modern disease diagnosis and treatment. Biosynthesized silver nanoparticles (AgNPs) are a class of eco-friendly, cost-effective and biocompatible agents that have attracted attention for their possible biomedical and bioengineering applications. Like many other inorganic and organic nanoparticles, such as AuNPs, iron oxide and quantum dots, AgNPs have also been widely studied as components of advanced anticancer agents in order to better manage cancer in the clinic. AgNPs are typically produced by the action of reducing reagents on silver ions. In addition to numerous laboratory-based methods for reduction of silver ions, living organisms and natural products can be effective and superior source for synthesis of AgNPs precursors. Currently, plants, bacteria and fungi can afford biogenic AgNPs precursors with diverse geometries and surface properties. In this review, we summarized the recent progress and achievements in biogenic AgNPs synthesis and their potential uses as anticancer agents.
