The World Health Organization (WHO) declared in March 12, 2020 the COVID-19 disease as pandemic. In Morocco, the first local transmission case was detected in March 13. The number of confirmed cases has gradually increased to reach 15,194 on July 10, 2020. To predict the COVID-19 evolution, statistical and mathematical models such as generalized logistic growth model [1], exponential model [2], segmented Poisson model [3], Susceptible-Infected-Recovered derivative models [4] and ARIMA [5] have been proposed and used. Herein, we proposed the use of the Hidden Markov Chain, which is a statistical system modelling transitions from one state (confirmed cases, recovered, active or death) to another according to a transition probability matrix to forecast the evolution of COVID-19 in Morocco from March 14, to October 5, 2020. In our knowledge the Hidden Markov Chain was not yet applied to the COVID-19 spreading. Forecasts for the cumulative number of confirmed, recovered, active and death cases can help the Moroccan authorities to set up adequate protocols for managing the post-confinement due to COVID-19. We provided both the recorded and forecasted data matrices of the cumulative number of the confirmed, recovered and active cases through the range of the studied dates.
We assessed how many peer-reviewed publications reporting chemical quantities and/or yields from electronic nicotine delivery systems (ENDS) have included adequate method validation characteristics in the publication for appropriate interpretation of data quality for informing tobacco regulatory science.
We searched 5 databases (Web of Knowledge, PubMed, SciFinder, Embase, EBSCOhost) for ENDS publications between January 2007 and September 2018. Of the 283 publications screened, 173 publications were relevant for analysis. We identified the publications that report a certain degree of control in data quality, ie, the publications that report marginally validated methods (MVMs). MVMs refer to the methods that (1) report 3 or more International Conference on Harmonisation (ICH) method validation characteristics, (2) state the method was validated, (3) cite their own previous publication(s) that report MVMs, or (4) use a method within the accreditation scope of an accredited laboratory.
Overall, 97 publications (56%) report MVMs in their studies. This percentage also reflects the publication distribution for the majority of the 28 chemicals measured by MVMs.
This study highlights the need for reporting sufficient validation characteristics following appropriate guidance to ensure the accuracy and reliability of the published analytical data for proper data interpretations that may support policy.

In our cross-sectional study, we aimed to determine age verification and sales of little cigars and cigarillos (LCCs) online to underage teens.
We selected 100 popular Internet Little Cigar and Cigarillo Vendors (ILVs) for order attempts. From August to December 2015, we supervised 14 teens 14-17 years old making order attempts for LCCs.
Of the 91 valid orders attempted, we received 89. https://www.selleckchem.com/products/img-7289.html For the valid orders attempted, 9.9% of ILVs used no age verification strategies at all, 84.6% used less effective forms of age verification, and 50.5% used more effective ones. Only one order was blocked during the order attempt and only one attempt was made to verify age at delivery. Most (79.8%) deliveries were left at the door and only 2 order attempts were rejected because of age verification strategies, resulting in a successful or valid buy rate of 97.8%.
Our study demonstrated that ILVs selling LCCs were not making adequate efforts to verify the age of their customers, at the point-of-**** or point-of-delivery, facilitating easy access by minors. Few ILVs utilized age verification strategies that prevented online sales of LCCs to underage teens.

Despite the beneficial properties of human milk (HM), it should be fortified to prevent extrauterine growth restriction; however, fortification of HM with a bovine-based human milk fortifier (BHMF) may induce feeding intolerance (FI) and necrotizing enterocolitis in preterm newborns. Herein, we have described the nutritional management of a preterm SGA newborn with intolerance to BHMF. A male infant was born at a gestational age of 32 weeks and 5 days, SGA weighing 1,490 grams ( less then 10th percentile). During BHMF use, he presented with symptoms of FI including abdominal distention, increased gastric residuals, and delayed enteral feeding advancement. Therefore, HM was fortified with carbohydrate powder, whey protein powder, and medium-chain triglycerides oil instead of BHMF to prevent FI and promote weight gain. Caloric density of feeds was increased once every 3 or 4 days by approximately 5 kcal/kg/day until an intake of 100 kcal/kg/day was achieved. Subsequently, his caloric and protein intake increased, growth rate improved, and full enteral feeding was achieved without any further symptom of FI. In conclusion, the symptoms of FI with BHMF in a preterm SGA neonate improved with the administration of a macronutrient fortified HM without compromising his enteral feed advancements, growth rate, and energy or protein intake.Ulcerative colitis (UC) is a chronic intestinal inflammation. Common clinical symptoms are weight loss, diarrhea, ulcers, and inflammation. Aloe vera (AV) has several medicinal properties including antioxidant, anti-inflammatory analgesic, and improvement of gastric and skin ulcers. This study aimed to investigate the protective and therapeutic effects of AV gel on acetic acid-induced UC in rats. UC was induced in 48 rats by injection of 4% acetic acid into the rectum. Protective and treatment groups received treatments 7 days before and after the induction of colitis, respectively. The negative control group, the positive control group, and AV groups received distilled water, sulfasalazine, and 50 and 300 mg/kg of gel extract, respectively. Water and food intake and body weight changes were recorded. The extent of the mucosal ulcers, colon tissue thickening, and mucosal bleeding were scored by the Gerald classification system score (microscopy observations). Slides of tissues were prepared for pathologic assay using the modified Wallace method (macroscopic observations).

In RIPC group, PTEN expression decreased, and mir-144 and Akt expression increased. The level of phosphorylated PTEN in the transfected microRNA-144 inhibitor group increased and the level of phosphorylated Akt reduced significantly. In conclusion, our results suggest that microRNA-144 may play a protective role in remote ischemic pretreatment by downregulating PTEN and upregulating Akt, suggesting that microRNA-144 via PTEN/Akt pathway may be of therapeutic significance in ischemic stroke.
Cumulative exposure to one or more anticholinergic medications ("anticholinergic burden") is associated with an increased risk of adverse outcomes, particularly among older individuals. Mirabegron, an oral selective β3-adrenergic receptor agonist, has demonstrated efficacy in managing the symptoms of overactive bladder without contributing to anticholinergic burden. However, it is not known whether the favorable safety profile of mirabegron relative to antimuscarinics varies with increasing age among a patient population who may have a high anticholinergic burden.
The primary objective of this study was to indirectly compare the safety and efficacy profile of mirabegron relative to antimuscarinics in older adults with overactive bladder.
A systematic literature review was conducted to identify randomized controlled trials that reported safety and efficacy endpoints among patients aged ≥ 65years. Identified randomized controlled trials were subsequently synthesized via a network meta-analysis. Preferred ompared with antimuscarinics among older adults. This includes safety outcomes typically associated with anticholinergic burden, which were less frequently observed in patients treated with mirabegron.
This study indicates that the safety and efficacy profile of mirabegron remains favorable compared with antimuscarinics among older adults. This includes safety outcomes typically associated with anticholinergic burden, which were less frequently observed in patients treated with mirabegron.
To assess the clinical variables that effect progression in patients with viable tumor after post-chemotherapy lymph node dissection due to disseminated non-seminomatous germ-cell tumors.
We performed a retrospective analysis of 32 patients with viable tumor after PC-RPLND, operated between 1990 and 2016. Patients were categorized into 2 groups as favorable and non-favorable (intermedia and poor) according to International Germ Cell Consensus Classification (IGCCC). Tumor size was determined as the largest dimension of retroperitoneal mass. Clinical factors and adjuvant chemotherapy were evaluated to impact on recurrence free survival (RFS) and overall survival (OS).
The median age of the patients and follow-up duration were 28.5 (17-51) years and 51.5 (4-253) months, respectively. 5-year RFS and OS were 57.8-66.8%, respectively. On univariate analysis, percentage of viable tumor, IGCCC risk group, primary site, second-line chemotherapy and surgical margin status were significant for RFS (p = 0.034, p = 0.002, p < 0.001, p = 0.011 and p < 0.001, respectively), while IGCCC risk group, second-line chemotherapy and surgical margin status were significant for OS (p = 0.004, p = 0.010 and p < 0.001, respectively). On multivariate analysis, second-line chemotherapy and surgical margin were independent risk factors for RFS (p = 0.016, HR 4.927 95% CI 1.34-18.02 and p < 0.001, OR 9.147 95% CI 2.61-31.98, respectively) and surgical margin status was the only predictor of OS (p = 0.038, HR 3.874 95% CI 1.07-13.69).
Retroperitoneal lymph node dissection with negative surgical margin is essential for patients with viable residual tumor after chemotherapy. Need for second-line chemotherapy shows risk of progression.

We proposed a novel treatment strategy, consisting of triweekly cisplatin plus dose-dense weekly paclitaxel before and after radical hysterectomy without adjuvant radiation therapy to treat locally advanced cervical cancer. However, cisplatin-related severe non-hematologic toxicities were frequent during this strategy. This study aimed to assess the applicability of replacing cisplatin with carboplatin in our proposed strategy.
Women with International Federation of Gynecology and Obstetrics (FIGO) 2008 stage IB2, IIA2, or IIB cervical cancer received three cycles of carboplatin (based on an area under the curve of six), each 21days apart, starting on day 1, and 80mg/m
of paclitaxel on days 1, 8, and 15 of each 21-day cycle before undergoing radical hysterectomy. Patients with one or more high-risk factors, including lymph vascular invasion, parametrial invasion, lymph-node metastasis, or positive margins, received three additional cycles of chemotherapy after hysterectomy. Concurrent chemoradiation thecally advanced cervical cancer. This strategy could considerably diminish the application of radiation therapy without reduced survival. A study to identify those patients who will benefit from this new multidisciplinary strategy is warranted.

A cornerstone of the linkage between non-human primate and human studies of the brain is magnetic resonance imaging, which allows for an association to be made between the detailed structural and physiological analysis of the non-human primate and that of the human brain. To further this end, we present a novel parcellation method and system for the rhesus monkey brain, referred to as the macaque Harvard-Oxford Atlas (mHOA), which is based on the human Harvard-Oxford Atlas (HOA) and grounded in an ontological and taxonomic framework. Consistent anatomical features were used to delimit and parcellate brain regions in the macaque, which were then categorized according to functional systems. This system of parcellation will be expanded with advances in technology and, like the HOA, will provide a framework upon which the results from other experimental studies (e.

Local radiation therapy (RT) can provide pain relief and reduce bleeding resulting from pleural or peritoneal dissemination of primary tumors. However, the optimal RT exposure dose for such tumors is unclear and the response rate is unknown. In this study, we examined the effectiveness of palliative RT for pleural or peritoneal disseminated tumors to determine the optimal dose in these patients.
The data of 22 patients with pleural- or peritoneal-disseminated tumors who were treated with local RT at our institution between 2011 and 2019 were retrospectively reviewed.
Among these patients, 9 (40.9%) had pleural tumors, 13 (59.1%) had peritoneal tumors and 2 had tumors in the peritoneum and umbilicus. The most common primary tumors were lung (22.8%) and pancreatic cancer (18.2%). RT was mainly administered for pain alleviation (72.7%). https://www.selleckchem.com/products/Fedratinib-SAR302503-TG101348.html Three patients (13.6%) received RT for hemostasis. Thirteen patients (59.1%) received a regimen of 30 Gy/10 fractions (fr), with the total dosage for all patients ranging from 27 to 56 Gy. No grade 2 or higher RT-related adverse events occurred. Three and four patients obtained complete and partial responses, respectively. The timing of the measurement of response to pain relief ranged from 0 to 232 (median, 21) days upon completion of RT. Overall response to pain relief occurred in nine of 16 patients (56.3%) with pain before RT. Hemostasis was confirmed in 2 of the 3 patients (66.7%) with bleeding before RT. Twelve of 20 (60%) patients with symptoms before RT responded to RT. Disease-specific survival (DSS) time after RT ranged from 1 to 656 (median, 106) days.
Prompt palliative administration of RT to patients with advanced disease to alleviate pain from disseminated tumors may achieve therapeutic efficacy.

Polyethylene glycol (PEG) has been widely used for bowel preparation. However, the efficacy and safety of single and split dose PEG for bowel preparation in children undergoing colonoscopy remain unclear, it is necessary to evaluate the role of single and split dose PEG for bowel preparation in children population.
PubMed et al. databases up to September 1, 2019 were systematically searched. Randomized controlled trials (RCTs) single and split dose PEG for bowel preparation in children undergoing colonoscopy were included. Based on the heterogeneity, data were synthesized using random-effects or fixed-effects models. Results were expressed as Mantel-Haenszel style odds ratio (OR) or mean difference (MD) with 95% confidence interval (95% CI).
Four RCTs with 249 children were included. There was no significantly difference in the efficacy of single and split dose PEG for bowel preparation (OR =0.36, 95% CI -0.12 to 1.10). The acceptability of split dose PEG for bowel preparation was significantly higher than that of single dose (OR =0.50, 95% CI 0.29 to 0.85); the incidence of nausea in split dose PEG for bowel preparation was significantly lower than that of single dose (OR =2.1, 95% CI 1.29 to 3.42); there was no significant difference on the incidence of abdominal pain between two regimes (OR =1.39, 95% CI 0.67 to 2.89).
Split dose PEG seems to be more superior to single dose for children undergoing colonoscopy. However, considering that the number of included RCTs are very limited, more related studies on this issue are needed in the future.

Early palliative care (PC) physician involvement alongside standard oncologic care has been recommended by the American Society of Clinical Oncology (ASCO) guidelines for all advanced cancer patients, although adherence to these guidelines is variable. Radiation oncologists (ROs) could help facilitate early PC referral for patients treated with palliative radiation, particularly those with brain metastasis (BRM), and the aim of this study was to evaluate the circumstances of PC referral at our institution to better understand the multidisciplinary approaches to facilitate it.
Patients diagnosed with BRM from non-small cell lung cancer (NSCLC) from 2012 to 2018 whose primary RO and MO were at our institution were reviewed. Overall survival and time to PC consultation from the first oncologic visit following BRM diagnosis was determined using the KaplanMeier method. Mann-Whitney U and Chi-Squared assessed for predictive factors for shorter time to PC consultation. For these factors, the overall survival, raon, though utilization has improved over time. As ROs are commonly involved in BRM management, they may be in a position to proactively support early PC consultations in this patient population.In the United States of America, almost 150,000 people are estimated to be diagnosed with colorectal cancer in 2020 and up to 35% of those are expected to present with oligometastatic disease. The term 'oligometastasis' was first used in 1995, however surgical literature describing liver resection for colorectal cancer dates **** to the 1940s. Five-year survival rates of up to 42% with surgery alone for solitary lesions are reported. Modern trials have demonstrated median overall survival rates of over 80 months for patients with colorectal liver metastases treated with perioperative chemotherapy. Colorectal liver metastases have accordingly been described as 'proof of concept' for the oligometastatic theory.

Thirteen patients (59.1%) received a regimen of 30 Gy/10 fractions (fr), with the total dosage for all patients ranging from 27 to 56 Gy. No grade 2 or higher RT-related adverse events occurred. Three and four patients obtained complete and partial responses, respectively. The timing of the measurement of response to pain relief ranged from 0 to 232 (median, 21) days upon completion of RT. Overall response to pain relief occurred in nine of 16 patients (56.3%) with pain before RT. Hemostasis was confirmed in 2 of the 3 patients (66.7%) with bleeding before RT. Twelve of 20 (60%) patients with symptoms before RT responded to RT. Disease-specific survival (DSS) time after RT ranged from 1 to 656 (median, 106) days. Prompt palliative administration of RT to patients with advanced disease to alleviate pain from disseminated tumors may achieve therapeutic efficacy.

Polyethylene glycol (PEG) has been widely used for bowel preparation. However, the efficacy and safety of single and split dose PEG for bowel preparation in children undergoing colonoscopy remain unclear, it is necessary to evaluate the role of single and split dose PEG for bowel preparation in children population. PubMed et al. databases up to September 1, 2019 were systematically searched. Randomized controlled trials (RCTs) single and split dose PEG for bowel preparation in children undergoing colonoscopy were included. Based on the heterogeneity, data were synthesized using random-effects or fixed-effects models. Results were expressed as Mantel-Haenszel style odds ratio (OR) or mean difference (MD) with 95% confidence interval (95% CI). Four RCTs with 249 children were included. There was no significantly difference in the efficacy of single and split dose PEG for bowel preparation (OR =0.36, 95% CI -0.12 to 1.10). The acceptability of split dose PEG for bowel preparation was significantly higher than that of single dose (OR =0.50, 95% CI 0.29 to 0.85); the incidence of nausea in split dose PEG for bowel preparation was significantly lower than that of single dose (OR =2.1, 95% CI 1.29 to 3.42); there was no significant difference on the incidence of abdominal pain between two regimes (OR =1.39, 95% CI 0.67 to 2.89). Split dose PEG seems to be more superior to single dose for children undergoing colonoscopy. However, considering that the number of included RCTs are very limited, more related studies on this issue are needed in the future.

Early palliative care (PC) physician involvement alongside standard oncologic care has been recommended by the American Society of Clinical Oncology (ASCO) guidelines for all advanced cancer patients, although adherence to these guidelines is variable. Radiation oncologists (ROs) could help facilitate early PC referral for patients treated with palliative radiation, particularly those with brain metastasis (BRM), and the aim of this study was to evaluate the circumstances of PC referral at our institution to better understand the multidisciplinary approaches to facilitate it. Patients diagnosed with BRM from non-small cell lung cancer (NSCLC) from 2012 to 2018 whose primary RO and MO were at our institution were reviewed. Overall survival and time to PC consultation from the first oncologic visit following BRM diagnosis was determined using the KaplanMeier method. Mann-Whitney U and Chi-Squared assessed for predictive factors for shorter time to PC consultation. For these factors, the overall survival, raon, though utilization has improved over time. As ROs are commonly involved in BRM management, they may be in a position to proactively support early PC consultations in this patient population.In the United States of America, almost 150,000 people are estimated to be diagnosed with colorectal cancer in 2020 and up to 35% of those are expected to present with oligometastatic disease. The term 'oligometastasis' was first used in 1995, however surgical literature describing liver resection for colorectal cancer dates back to the 1940s. Five-year survival rates of up to 42% with surgery alone for solitary lesions are reported. Modern trials have demonstrated median overall survival rates of over 80 months for patients with colorectal liver metastases treated with perioperative chemotherapy. Colorectal liver metastases have accordingly been described as 'proof of concept' for the oligometastatic theory.0 Comentários 0 Compartilhamentos 24 Visualizações 0 Anterior -
Between the 1st and 2nd generator change and the 2nd and 3rd there were no cases of inappropriate ATP or shock. https://www.selleckchem.com/products/cpi-455.html Overall, 42 patients out of the 88 had appropriate therapy (47.7%) and 7 patients had inappropriate therapy (8.0%).
Most patients with ICDs do not receive therapy and a minority have inappropriate therapy which typically occur before the first generator change as we observed no inappropriate therapy beyond the first generator change.

The identification of mutated proteins in human cancer cells-termed proteogenomics, requires several technologically independent research methodologies including DNA variant identification, RNA sequencing, and mass spectrometry. Any one of these methodologies are not optimized for identifying potential mutated proteins and any one output fails to cover completely a specific landscape.
An isogenic melanoma cell with a p53-null genotype was created by CRISPR/CAS9 system to determine how p53 gene inactivation affects mutant proteome expression. A mutant peptide reference database was developed by comparing two distinct DNA and RNA variant detection platforms using these isogenic cells. Chemically fractionated tryptic peptides from lysates were processed using a TripleTOF 5600+ mass spectrometer and their spectra were identified against this mutant reference database.
Approximately 190 mutated peptides were enriched in wt-p53 cells, 187 mutant peptides were enriched in p53-null cells, with an overlap of 147 mutated peptides. STRING analysis highlighted that the wt-p53 cell line was enriched for mutant protein pathways such as CDC5L and POLR1B, whilst the p53-null cell line was enriched for mutated proteins comprising EGF/YES, Ubiquitination, and RPL26/5 nodes.
Our study produces a well annotated p53-dependent and p53-independent mutant proteome of a common melanoma cell line model. Coupled to the application of an integrated DNA and RNA variant detection platform (CLCbio) and software for identification of proteins (ProteinPilot), this pipeline can be used to detect high confident mutant proteins in cells.
This pipeline forms a blueprint for identifying mutated proteins in diseased cell systems.

GH74 xyloglucanases are composed of two separate domains connected by two unstructured peptides. Previously, a hypothesis was made that the movement of domains may affect the enzyme mechanism of catalysis.
The molecular dynamics (MD) simulations of endo-processive xyloglucanases from Paenibacillus odorifer (PoGH74
) and Myceliophthora thermophila (MtXeg74A) were carried out.
MD simulations for both enzymes in complex with XXLG and XGXXLG oligosaccharides confirmed the possibility of domain movement. In the case of MtXeg74A, changes in the distances between C
atoms of aromatic residues involved in xyloglucan binding in -3 and+3 subsites of the active site cleft and those of selected residues on the opposite side of the cleft reached values up to 10-12Å. For PoGH74
the conformational changes were less pronounced. In MtXeg74A variants, the deletion of loop 1, which partially closes the entrance to the cleft, and the additional double mutation of two Trp residues in +3 and+5 subsites caused the enhanced mobility of the XGXXLG and also induced changes in topography of the cleft.
These findings demonstrate the possibility of existence of GH74 xyloglucanases in a more open and more closed enzyme conformation. The enzyme in an open conformation may more easily accommodate the branched polysaccharide, while its transition to the closed conformation, together with loop 1 function, should aid processivity.
Our results provide an insight into a mechanism of action of GH74 xyloglucanases and may be useful for discussing the catalytic mechanisms of glycoside hydrolases from other families.

We report our early experience with a cohort of patients who were able to proceed to allogeneic hematopoietic cell transplantation (alloHCT) after HMA-VEN therapy. Thirty-two patients with AML (19 r/r and 13 de novo) with a median age of 62 years underwent alloHCT after HMA-VEN therapy. Twenty-two (68.8%) were in complete remission (CR)/CR with incomplete count recovery at time of HCT. With a median follow up of 14.4 months, the 1-year overall survival (OS) was 62.5%, and disease-free survival was 43.8%. The 1-year nonrelapse mortality rate was 18.8%, and the cumulative incidence of relapse was 37.5%. Among patients who underwent alloHCT in CR, the 1-year OS was 77.3%, and the cumulative incidence of nonrelapse mortality was 9.1%. The cumulative incidence of grade II-IV acute graft-versus-host disease was 43.8%. We conclude that alloHCT after HMA-VEN is therapy associated with favorable allogeneic HCT outcomes in newly diagnosed older patients with AML, as well as those with r/r AML.Organ transplantation remains the gold standard therapeutic option for patients with end-stage organ failure. However, there have been few improvements in the management of post-transplant immunosuppression. As the long-term use of immunosuppressive agents (ISAs) may result in off-target systemic toxicity and complications, minimizing the ISA dosage while preserving the pharmacological efficacy could be a promising solution to address these challenges. Here, we present the design and application of self-assembled prodrug nanoparticles based on chemically derived mycophenolate mofetil, which further provide a hydrophobic core to noncovalently encapsulate additional ISAs such as tacrolimus. The resulting immunosuppressant cocktail nanoparticles are further refined by PEGylation with amphiphilic polymers to form colloidally stable self-assembled immunosuppressant cocktails (SAICs) that are suitable for preclinical studies. In a rat model of allogeneic orthotopic liver transplantation (OLT), administration of SAICs markedly extends graft/recipient survival, retards weight loss and attenuates allograft damage.

86 to 160.67 mg CO2 kg-1 d-1. SMBC and BR values were higher in Cierva Point, followed by Fildes Peninsula and Deception Island, showing the same trend of SOM abundance. Except for Cierva Point, low nitrogen, phosphorus and C concentrations were observed. SMBC/total organic carbon (TOC) levels indicated that SOC was recalcitrant and SOM content was closely related to the extent of vegetation cover observed in situ. High metabolic quotient values obtained at Cierva Point and Deception Island (median values 7.27 and 6.53 mg C-CO2 g SMBC-1 h-1) and low SMBC/TOC in Cierva Point suggest a poor efficiency of the microbial populations in the consumption of the SOC. High SMBC/TOC values obtained in Deception Island indicates that SMBC may influence SOM stabilization. Mineralization rates were very low (negligible values to 1.44%) and sites with the lowest values had the highest SOM.Various recent studies have shown that societal efforts to mitigate (e.g. "lockdown") the outbreak of the 2019 coronavirus disease (COVID-19) caused non-negligible impacts on the environment, especially air quality. To examine if interventional policies due to COVID-19 have had a similar impact in the US state of California, this paper investigates the spatiotemporal patterns and changes in air pollution before, during and after the lockdown of the state, comparing the air quality measurements in 2020 with historical averages from 2015 to 2019. Through time series analysis, a sudden drop and uptick of air pollution are found around the dates when shutdown and reopening were ordered, respectively. The spatial patterns of nitrogen dioxide (NO2) tropospheric vertical column density (TVCD) show a decreasing trend over the locations of major powerplants and an increasing trend over residential areas near interactions of national highways. Ground-based observations around California show a 38%, 49%, and 31% drop in the concentration of NO2, carbon monoxide (CO) and particulate matter 2.5 (PM2.5) during the lockdown (March 19-May 7) compared to before (January 26-March 18) in 2020. These are 16%, 25% and 19% sharper than the means of the previous five years in the same periods, respectively. Our study offers evidence of the environmental impact introduced by COVID-19, and insight into related economic influences.Salt marshes, due to their capability to bury soil carbon (C), are potentially important regional C sinks. Efforts to restore tidal flow to former salt marshes have increased in recent decades in New England (USA), as well as in some other parts of the world. In this study, we investigated plant biomass and carbon dioxide (CO2) fluxes at four sites where restoration of tidal flow occurred five to ten years prior to the study. https://www.selleckchem.com/products/ctpi-2.html Site elevation, aboveground biomass, CO2 flux, and porewater chemistry were measured in 2015 and 2016 in both restored marshes and adjacent marshes where tidal flow had never been restricted. We found that the elevation in restored marsh sites was 2-16 cm lower than their natural references. Restored marshes where porewater chemistry was similar to the natural reference had greater plant aboveground biomass, gross ecosystem production, ecosystem respiration, as well as net ecosystem CO2 exchange (NEE) than the natural reference, even though they had the same plant species. We also compared respiration rates in aboveground biomass (AR) and soil (BR) during July 2016, and found that restored marshes had higher AR and BR fluxes than natural references. Our findings indicated that well-restored salt marshes can result in greater plant biomass and NEP, which has the potential to enhance rates of C sequestration at 10-yrs post restoration. Those differences were likely due to lower elevation and greater flooding frequency in the recently restored marshes than the natural marsh. The inverse relationship between elevation and productivity further suggests that, where sea-level rise rate does not surpass the threshold of plant survival, the restoration of these salt marshes may lead to enhanced organic and mineral sedimentation, extending marsh survival under increased sea level, and recouping carbon stocks that were lost during decades of tidal restriction.This study is an attempt to quantitatively test and compare novel advanced-machine learning algorithms in terms of their performance in achieving the goal of predicting flood susceptible areas in a low altitudinal range, sub-tropical floodplain environmental setting, like that prevailing in the Middle Ganga Plain (MGP), India. This part of the Ganga floodplain region, which under the influence of undergoing active tectonic regime related subsidence, is the hotbed of annual flood disaster. This makes the region one of the best natural laboratories to test the flood susceptibility models for establishing a universalization of such models in low relief highly flood prone areas. Based on highly sophisticated flood inventory archived for this region, and 12 flood conditioning factors viz. annual rainfall, soil type, stream density, distance from stream, distance from road, Topographic Wetness Index (TWI), altitude, slope aspect, slope, curvature, land use/land cover, and geomorphology, an advanced novel hybrid modsceptibility models. This will further help establishing a benchmark model with capability of highest accuracy and sensitivity performance in the similar topographic and climatic setting taking assumption of the quality of input parameters as constant.This work examined the adsorption capacity of sugarcane bagasse (SB) for the removal of ciprofloxacin (CPX) from water using batch experiments and a fixed bed column and compared its adsorption performance with a powdered activated commercial carbon (PAC). Both adsorbents achieved a similar percentage removal of about 78% with doses of 3 g L-1 of SB and 0.3 g L-1 of PAC (20 mg L-1 initial CPX concentration at 30 °C). The maximum removal was obtained at a pH between 6 and 8. SB adsorption isotherms were fitted to the Langmuir, BET and Freundlich models showing a maximum adsorption capacity of 13.6 mg g-1. The kinetic data for both SB and PAC fitted the pseudo second-order model (R2 = 0.99). The adsorption process was faster on the SB (65% of elimination in the first 5 min) than on the PAC. The study of the adsorbent properties shows that SB is a macroporous solid with a specific surface area 250 times smaller than PAC. The thermodynamic results show that SB adsorption was physical and exothermic. The main suggested interactions between CPX and SB are electrostatic attraction, hydrogen bonding and dipole-dipole interactions.

Paget-Schroetter syndrome is a form of primary venous thoracic outlet syndrome whereby thrombosis of the subclavian vein is instigated by repeated and vigorous overhead activity of the arm. We describe a 35-year-old pregnant white woman at 8 weeks' gestation, a competitive swimmer by profession, who was diagnosed with a left upper extremity thrombus. First rib resection through an infraclavicular approach was performed 1 week after percutaneous pharmacomechanical thrombectomy. Repeated venography demonstrated residual thrombus requiring percutaneous pharmacomechanical thrombectomy with balloon venoplasty. We present a challenging case with focus on the unique diagnostic evaluation and management of pregnant patients with this condition. © 2019 The Authors.Inferior vena cava filter placement during extracorporeal membranous oxygenation decannulation has been described as a technique to prevent potentially lethal pulmonary embolism in this critically ill population. With long-standing extracorporeal membranous oxygenation cannulae, venous fibrin sheaths may develop, which may predispose to filter maldeployment or inadequate embolus filtration. This report describes the use of a balloon catheter to disrupt a fibrin sheath at patient bedside using intravascular ultrasound guidance to facilitate inferior vena cava filter placement. © 2019 The Author(s).An arteriovenous malformation is a rare vascular anomaly composed of a complex network of interconnected arteries and veins of the scalp. It is usually congenital, but infrequently occurs after trauma. Over the years, several terms have been used to describe these lesions, such as cirsoid/rasemose/arteriovenous aneurysm, plexiform angioma and aneurysma serpentinum, or arteriovenous fistula when a single connection exists. Head and neck malformations occur in 0.1% of the population. Involvement of the superficial temporal artery is rare, occurring in about 0.5% to 2.0% of cases. They are diagnosed by angiography and can be managed by endovascular or open resection. The case of a 23-year-old man who presented with a pulsatile head mass after blunt trauma 5 years prior is presented. This entity was diagnosed as an arteriovenous malformation supplied by the superficial temporal arteries. He subsequently underwent successful open exploration and resection. The information is presented with the patient's consent. © 2019 The Authors.A 50-year-old woman was referred to the noninvasive vascular laboratory for carotid artery evaluation because of a bruit in the neck. Color Doppler ultrasound examination demonstrated absence of the right common carotid artery and parallel internal and external carotid arteries originating at the brachiocephalic trunk. Computed tomography angiography further described anomalous anatomy, demonstrating a common origin of the innominate artery and left common carotid artery. Knowledge of such unusual anatomy may become valuable in future evaluation or treatment of this patient. © 2019 The Author(s).A pancreaticoduodenal artery arcade aneurysm (PDAA) is rare and often associated with celiac axis stenosis by the median arcuate ligament. Although rupture risk of the PDAA is not related to its size, treatment guidelines are absent. Here we describe a 59-year-old woman with multiple ruptured PDAAs associated with celiac axis stenosis who was successfully treated with coil embolization. As follow-up computed tomography revealed rapid expansion of residual PDAAs and new gastric artery dissection, median arcuate ligament resection was followed by aorta-common hepatic artery bypass, which resulted in aneurysmal regression. Blood flow modification might prevent secondary rupture of PDAA associated with celiac axis stenosis. © 2019 The Authors.Middle aortic syndrome (MAS), a coarctation of the lower thoracic and/or abdominal aorta, is typically diagnosed and treated in the pediatric population. We present a 48-year-old patient with a long-standing history of hypertension who was lost to follow-up owing to a lack of insurance coverage. After two myocardial infarcts owing to severe hypertension, a vascular workup including a computed tomography angiogram revealed a diagnosis of MAS. He underwent open vascular reconstruction with a thoracoabdominal Dacron bypass graft. He was discharged within 1 week with no hypertension or claudication. Adult patients diagnosed with MAS should undergo open or endovascular surgical repair with close follow-up. © 2019 The Author(s).The human gene MUTYH codes for a DNA glycosylase involved in the repair of oxidative DNA damage. Faulty MUTYH protein activity causes the accumulation of G→T transversions due to unrepaired 8-oxoGA mismatches. MUTYH germ-line mutations in humans are linked with a recessive form of Familial Adenomatous Polyposis (FAP) and colorectal cancer predisposition. We studied the repair capacity of variants identified in MUTYH-associated polyposis (MAP) patients. MAP is inherited in an autosomal recessive type due to mutations in MUTYH (Y165C, G382D, P54S, A22V, Q63R, G45D, S136P and N43S), indicating that both copies of the gene become inactivated. However, the parents of an individual with an autosomal recessive condition may serve as carriers, each harboring one copy of the mutated gene without showing signs or symptoms of MAP. Six protein partners have been associated with MUTYH, four via direct physical interactions, namely, hMSH6, hPCNA, hRPA1, and hAPEX1. https://www.selleckchem.com/products/bi-d1870.html We examined, for the first time, specific interactions of these protein partners with MAP-associated MUTYH mutants using molecular dynamics simulations. The approach provided tools for exploration of the conformational energy landscape accessible to protein partners. The investigation also determined the impact before and after energy minimization of protein-protein interactions and binding affinities of MUTYH wild type and mutant forms, as well as the interactions with other proteins. Taken together, this study provided new insights into the role of MUTYH and its interacting proteins in MAP. © 2020 Production and hosting by Elsevier B.V. on behalf of KeAi Communications Co., Ltd.
Paget-Schroetter syndrome is a form of primary venous thoracic outlet syndrome whereby thrombosis of the subclavian vein is instigated by repeated and vigorous overhead activity of the arm. We describe a 35-year-old pregnant white woman at 8 weeks' gestation, a competitive swimmer by profession, who was diagnosed with a left upper extremity thrombus. First rib resection through an infraclavicular approach was performed 1 week after percutaneous pharmacomechanical thrombectomy. Repeated venography demonstrated residual thrombus requiring percutaneous pharmacomechanical thrombectomy with balloon venoplasty. We present a challenging case with focus on the unique diagnostic evaluation and management of pregnant patients with this condition. © 2019 The Authors.Inferior vena cava filter placement during extracorporeal membranous oxygenation decannulation has been described as a technique to prevent potentially lethal pulmonary embolism in this critically ill population. With long-standing extracorporeal membranous oxygenation cannulae, venous fibrin sheaths may develop, which may predispose to filter maldeployment or inadequate embolus filtration. This report describes the use of a balloon catheter to disrupt a fibrin sheath at patient bedside using intravascular ultrasound guidance to facilitate inferior vena cava filter placement. © 2019 The Author(s).An arteriovenous malformation is a rare vascular anomaly composed of a complex network of interconnected arteries and veins of the scalp. It is usually congenital, but infrequently occurs after trauma. Over the years, several terms have been used to describe these lesions, such as cirsoid/rasemose/arteriovenous aneurysm, plexiform angioma and aneurysma serpentinum, or arteriovenous fistula when a single connection exists. Head and neck malformations occur in 0.1% of the population. Involvement of the superficial temporal artery is rare, occurring in about 0.5% to 2.0% of cases. They are diagnosed by angiography and can be managed by endovascular or open resection. The case of a 23-year-old man who presented with a pulsatile head mass after blunt trauma 5 years prior is presented. This entity was diagnosed as an arteriovenous malformation supplied by the superficial temporal arteries. He subsequently underwent successful open exploration and resection. The information is presented with the patient's consent. © 2019 The Authors.A 50-year-old woman was referred to the noninvasive vascular laboratory for carotid artery evaluation because of a bruit in the neck. Color Doppler ultrasound examination demonstrated absence of the right common carotid artery and parallel internal and external carotid arteries originating at the brachiocephalic trunk. Computed tomography angiography further described anomalous anatomy, demonstrating a common origin of the innominate artery and left common carotid artery. Knowledge of such unusual anatomy may become valuable in future evaluation or treatment of this patient. © 2019 The Author(s).A pancreaticoduodenal artery arcade aneurysm (PDAA) is rare and often associated with celiac axis stenosis by the median arcuate ligament. Although rupture risk of the PDAA is not related to its size, treatment guidelines are absent. Here we describe a 59-year-old woman with multiple ruptured PDAAs associated with celiac axis stenosis who was successfully treated with coil embolization. As follow-up computed tomography revealed rapid expansion of residual PDAAs and new gastric artery dissection, median arcuate ligament resection was followed by aorta-common hepatic artery bypass, which resulted in aneurysmal regression. Blood flow modification might prevent secondary rupture of PDAA associated with celiac axis stenosis. © 2019 The Authors.Middle aortic syndrome (MAS), a coarctation of the lower thoracic and/or abdominal aorta, is typically diagnosed and treated in the pediatric population. We present a 48-year-old patient with a long-standing history of hypertension who was lost to follow-up owing to a lack of insurance coverage. After two myocardial infarcts owing to severe hypertension, a vascular workup including a computed tomography angiogram revealed a diagnosis of MAS. He underwent open vascular reconstruction with a thoracoabdominal Dacron bypass graft. He was discharged within 1 week with no hypertension or claudication. Adult patients diagnosed with MAS should undergo open or endovascular surgical repair with close follow-up. © 2019 The Author(s).The human gene MUTYH codes for a DNA glycosylase involved in the repair of oxidative DNA damage.

01, OR 0.55). There was no significant difference in the incidence of bleeding requiring transfusion between AF and no AF cohorts (29.3 vs. 24.2%, p = 0.09, OR 1.15). LOS was shorter in patients with AF (32.9 vs. 36.7 mean days, p less then 0.001). Patients with AF had lower in-hospital mortality (8.9 vs. 14.9%, p less then 0.001, OR 0.48). In a large real-world US cohort of patients undergoing LVAD implantation, a diagnosis of AF was common among device recipients. After adjustment for demographics and comorbidities, AF was associated with reduced TE events and in-hospital mortality.OBJECTIVE To report the incidence of cancer after renal transplantation at a referral center in a developing country. MATERIALS AND METHODS Consecutive patients receiving renal transplantations during a 48-year period at Instituto Nacional de Ciencias Medicas y Nutricion Salvador Zubiran were analyzed. The standardized incidence ratio (SIR) was calculated based on data from GLOBOCAN 2012. RESULTS From 1257 patients, 98 (8%) developed 143 malignancies. The SIR of all the cohort was 4.1 (95% CI 3.2-5.1). The relative risks of male and female transplant recipients were 4.6 and 3.5 times greater than the risk of cancer of the general population, respectively. The most common malignancy was non-melanoma skin cancer (52%). The malignancy that associated with the greater relative risk was Kaposi sarcoma (SIR 200), followed by lymphomas (SIR 30). A multivariate analysis comparing patients with cancer and controls confirmed that receiving a three-drug regimen as final treatment, prolonged immunosuppression, and patients undergoing a second renal transplantation were factors associated with increased cancer development. CONCLUSION To date, there is paucity of data from developing countries. We reported the results from a National Health Institute in Mexico including a large cohort with a long follow-up, demonstrating differences within frequencies and risks compared to other regions of the world.PURPOSE Cardiovascular disease (CVD) is a major non-cancer cause of mortality among cancer survivors, and statin therapy is the mainstay of cardiovascular risk management. However, little is known about adherence to statin therapy relative to current guidelines for the management of cholesterol among cancer survivors. We investigated the prevalence of statin-eligible but untreated individuals among cancer survivors and factors associated with underuse of statins. METHODS We used US National Health and Nutrition Examination Survey data (2011-2016) and identified 706 cancer survivors and matched controls (12) by age and sex. We identified participants who met the American College of Cardiology/American Heart Association (2018) guidelines but were not currently in treatment. We estimated the proportion of patients who were statin-eligible but untreated and performed multivariable logistic regression analysis to identify the factors associated with underuse of statins. RESULTS The mean age of the total sample was 62.2 years (standard deviation, 9.1). Among the total participants, 37.5% of cancer survivors and 37.2% of controls were statin-eligible but untreated. The crude statin-eligible untreated proportion was 41.2% among cancer survivors who had received a cancer diagnosis within 3 years and 40.3% among long-term survivors of 10 years or more. In multivariate analysis, old age, male sex, lack of a usual source of care, current smoking, and low household income were significantly associated with statin-eligible untreated status. https://www.selleckchem.com/products/procyanidin-c1.html CONCLUSIONS AND IMPLICATIONS FOR CANCER SURVIVORS More than one-third of cancer survivors were statin-eligible but untreated under current guidelines. There is room for improvement to reduce the burden of non-cancer mortality by managing traditional cardiovascular risk factors.BACKGROUND Social connectedness exerts strong influences on health, including major depression and suicide. A major component of social connectedness is having individual relationships with close supports, romantic partners, and other trusted members of one's social network. OBJECTIVE The objective of this study was to understand how individuals' relationships with close supports might be leveraged to improve outcomes for primary care patients with depression and at risk for suicide. DESIGN In this qualitative study, we used a semi-structured interview guide to probe patient experiences, views, and preferences related to social support. PARTICIPANTS We conducted interviews with 30 primary care patients at a Veterans Health Administration (VA) medical center who had symptoms of major depression and a close support. APPROACH Thematic analysis of qualitative interview data examined close supports' impact on patients. We iteratively developed a codebook, used output from codes to sort data into themes, and selectsing attitudinal barriers to allowing help and involvement of close supports.Social determinants of health (SDoH) are the conditions in which people live and work that shape access to essential social and economic resources. Calls for healthcare systems to intervene on unmet social needs have stimulated several large-scale initiatives across the country. Yet, such activities are underway in the absence of a unifying conceptual framework outlining the potential mechanisms by which healthcare-based unmet social need interventions can improve health outcomes. Drawing on theoretical foundations and empirical evidence about the relationship between unmet social needs and health, the authors developed the OASIS (Outcomes from Addressing SDoH in Systems) conceptual framework to map the known and hypothesized pathways by which unmet social need screening and referral interventions may impact outcomes. The OASIS framework may help guide policy makers, healthcare system leaders, clinicians, and researchers to utilize a more unified approach in their efforts to implement and evaluate unmet social need interventions and thus foster the development of an evidence base to inform healthcare systems to more effectively mitigate the consequences of unmet social needs. Adopting an overarching conceptual framework for addressing unmet social needs by healthcare systems holds promise for better achieving health equity and promoting health at the individual and population levels.

The three studies employed both low and high fat rodent diets, as well as more complex diets emulating the U.S. dietary pattern. The ω-3 HUFA scores in RBCs were comparatively more robust than the O3I at predicting HUFA balances in the kidney, liver, spleen, and lung. Importantly, increases in both the ω-3 HUFA score (>40%) and the O3I (>10%) were strongly associated with suppression of cSiO2-triggered (1) expression of interferon-regulated genes, proinflammatory cytokine production, leukocyte infiltration, and ectopic lymphoid structure development in the lung, (2) pulmonary and systemic autoantibody production, and (3) glomerulonephritis. Collectively, these findings identify achievable ω-3 HUFA scores and O3I thresholds that could be targeted in future human intervention studies querying how ω-3 HUFA consumption influences lupus and other autoimmune diseases.Immunoglobulin G4-related disease (IgG4-RD) is a newly defined disease entity, while the exact pathogenesis is still not clear. Identifying the characters of IgG4-RD in proteomic and transcriptomic aspects will be critical to investigate the potential pathogenic mechanisms of IgG4-RD. We performed proteomic analysis realized with iTRAQ technique for serum samples from eight treatment-naive IgG4-RD patients and eight healthy volunteers, and tissue samples from two IgG4-RD patients and two non-IgG4-RD patients. Transcriptomic data (GSE40568 and GSE66465) was obtained from the GEO Dataset for validation. The weighted correlation network analysis (WGCNA) was applied to detect the gene modules correlated with IgG4-RD. KEGG pathway analysis was used to investigate pathways enriched in IgG4-RD samples. https://www.selleckchem.com/products/azd6738.html As a result, a total of 980 differentially expressed proteins (DEPs) in tissue and 94 DEPs in serum were identified between IgG4-RD and control groups. Three hundred fifty-four and two hundred forty-seven genes that most correlated with IgG4-RD were detected by WGCNA analysis in tissue and PBMC, respectively. We also found that DEPs in IgG4-RD samples were enriched in several immune-related activities including bacterial/viral infections and platelet activation as well as some immune related signaling pathways. In conclusion, we identified multiple processes/factors and several signaling pathways that may involve in the IgG4-RD pathogenesis, and found out some potential therapeutic targets for IgG4-RD.Inhibitory receptors are crucial immune regulators and are essential to prevent exacerbated responses, thus contributing to immune homeostasis. Leukocyte associated immunoglobulin like receptor 1 (LAIR-1) is an immune inhibitory receptor which has collagen and collagen domain containing proteins as ligands. LAIR-1 is broadly expressed on immune cells and has a large availability of ligands in both circulation and tissues, implicating a need for tight regulation of this interaction. In the current study, we sought to examine the regulation and function of LAIR-1 on monocyte, dendritic cell (DC) and macrophage subtypes, using different in vitro models. We found that LAIR-1 is highly expressed on intermediate monocytes as well as on plasmacytoid DCs. LAIR-1 is also expressed on skin immune cells, mainly on tissue CD14+ cells, macrophages and CD1c+ DCs. In vitro, monocyte and type-2 conventional DC stimulation leads to LAIR-1 upregulation, which may reflect the importance of LAIR-1 as negative regulator under inflammatory conditions. Indeed, we demonstrate that LAIR-1 ligation on monocytes inhibits toll like receptor (TLR)4 and Interferon (IFN)-α- induced signals. Furthermore, LAIR-1 is downregulated on GM-CSF and IFN-γ monocyte-derived macrophages and monocyte-derived DCs. In addition, LAIR-1 triggering during monocyte derived-DC differentiation results in significant phenotypic changes, as well as a different response to TLR4 and IFN-α stimulation. This indicates a role for LAIR-1 in skewing DC function, which impacts the cytokine expression profile of these cells. In conclusion, we demonstrate that LAIR-1 is consistently upregulated on monocytes and DC during the inflammatory phase of the immune response and tends to restore its expression during the resolution phase. Under inflammatory conditions, LAIR-1 has an inhibitory function, pointing toward to a potential intervention opportunity targeting LAIR-1 in inflammatory conditions.One of the main functions of the human placenta is to provide a barrier between the fetal and maternal blood circulations, where gas exchange and transfer of nutrients to the developing fetus take place. Despite being a barrier, there is a multitude of crosstalk between maternal immune cells and fetally derived semi-allogeneic trophoblast cells. Therefore, the maternal immune system has a difficult task to both tolerate the fetus but at the same time also defend the mother and the fetus from infections. Mucosal-associated invariant T (MAIT) cells are an increasingly recognized subset of T cells with anti-microbial functions that get activated in the context of non-polymorphic MR1 molecules, but also in response to inflammation. MAIT cells accumulate at term pregnancy in the maternal blood that flows into the intervillous space inside the placenta. Chemotactic factors produced by the placenta may be involved in recruiting and retaining particular immune cell subsets, including MAIT cells. In this Mini-Review, we describe what is known about MAIT cells during pregnancy and discuss the potential biological functions of MAIT cells at the fetal-maternal interface. Since MAIT cells have anti-microbial and tissue-repairing functions, but lack alloantigen reactivity, they could play an important role in protecting the fetus from bacterial infections and maintaining tissue homeostasis without risks of mediating harmful responses toward semi-allogenic fetal tissues.Chimeric antigen receptor (CAR) T cells represent a potentially curative therapy for patients with advanced hematological cancers; however, uncertainties surround the cell-intrinsic fitness as well as the exhaustion that restrict the capacity of CAR-T. Decitabine (DAC), a DNA demethylating agent, has been demonstrated to reverse exhaustion-associated DNA-methylation programs and to improve T cell responses against tumors. Here we show that DAC significantly enhances antileukemia functions of CD123 CAR-T cells in vitro and in vivo. Additionally, it inhibits the expression of DMNT3a and DNMT1. Using the Illumina Methylation EPIC BeadChip (850 K), we identified differentially methylated regions, most of which undergo hypomethylated changes. Transcriptomic profiling revealed that CD123 CAR-T cells treated with DAC were enriched in genes associated with naive, early memory T cells, as well as non-exhausted T cells. DAC treatment also results in upregulation of immune synapse-related genes. Finally, our data further suggest that DAC works through the regulation of cellular differentiation characterized by naive and memory phenotypes.

This observation may be key for the future crystal engineering of heterocyclic chalcones for pharmaceutical applications.Controversy in the description/identification of so-called intermediate phase(s) in PbHfO3, stable in the range ∼420-480 K, has existed for a few decades. A synchrotron diffraction experiment on a partially detwinned crystal allowed the structure to be solved in the superspace group Imma(00γ)s00 (No. 74.2). In contrast to some previously published reports, in the pure compound only one distinct phase was observed between Pbam PbZrO3-like antiferroelectric and Pm3m paraelectric phases. The modulation vector depends only slightly on temperature. The major structure modulation is associated with the displacement of lead ions, which is accompanied by a smaller amplitude modulation for the surrounding O atoms and tilting of HfO6 octahedra. Tilting of the octahedra results in a doubling of the unit cell compared with the parent structure.Crystals of the first synthetic copper tellurite arsenate, CuII5(TeIVO3)2(AsVO4)2 [systematic name pentacopper(II) bis-oxotellurate(IV) bis-oxoarsenate(V)], were grown by the chemical vapour transport method and structurally determined using single-crystal X-ray diffraction. CuII5(TeIVO3)2(AsVO4)2 possesses a novel structure type including a new topological arrangement of CuII and O atoms. CuII5(TeIVO3)2(AsVO4)2 is formed from a framework of two types of Jahn-Teller distorted [CuIIO6] octahedra (one of which is considerably elongated) and [CuIIO5] square pyramids, which are linked by edge-sharing to form chains and dimers and by corner-sharing to complete a three-dimensional framework. [AsVO4] tetrahedra and [TeIVO5] polyhedra bridge the edges of channels along the a-axis direction, with void space remaining for the TeIV stereoactive 5s2 lone pairs. A comparison is made between the crystal structure of CuII5(TeIVO3)2(AsVO4)2 and those of known compounds and minerals, in particular fumarolitic Cu minerals.The effects of temperature (100-370 K) and pressure (0-6 GPa) on the non-localized two-electron multicentric covalent bonds (`pancake bonding') in closely bound radical dimers were studied using single-crystal X-ray diffraction on a 4-cyano-N-methylpyridinium salt of 5,6-dichloro-2,3-dicyanosemiquinone radical anion (DDQ) as the sample compound. On cooling, the anisotropic structural compression was accompanied by continuous changes in molecular stacking; the discontinuities in the changes in volume and b and c cell parameters suggest that a phase transition occurs between 210 and 240 K. At a pressure of 2.55 GPa, distances between radical dimers shortened to 2.9 Å, which corresponds to distances observed in extended π-bonded polymers. Increasing pressure further to 6 GPa reduced the interplanar separation of the radicals to 2.75 Å. This may indicate that the covalent component of the interaction significantly increased, in accordance with the results of DFT calculations reported elsewhere [Molčanov et al. (2019), Cryst. Growth Des. 19, 391-402].The crystal structure of diaquabis(omeprazolate)magnesium dihydrate (DABOMD) in the solid state has been determined using single-crystal X-ray diffraction. Single crystals of DABOMD were obtained by slow crystallization in ethanol with water used as an antisolvent. The crystal structure shows a dihydrated salt comprising a magnesium cation coordinating two omeprazolate anions and two water molecules (W1) that are strongly bound to magnesium. In addition, two further water molecules (W2) are more weakly hydrogen-bonded to the pyridine nitrogen atom of each omeprazolate anion. The crystal structure was utilized to estimate key material properties for DABOMD, including crystal habit and mechanical properties, which are required for improved understanding and prediction of the behaviour of particles during pharmaceutical processing such as milling. The results from the material properties calculations indicate that DABOMD exhibits a hexagonal morphology and consists of a flat slip plane through the (100) face. It can be classed as a soft material based on elastic constant calculation and exhibits a two-dimensional hydrogen-bonding framework. Based on the crystal structure, habit and mechanical properties, it is anticipated that DABOMD will experience large disorder accompanied by plastic deformation during milling.This paper discusses the full structural solution of the hybrid perovskite formamidinium lead tribromide (FAPbBr3) and its temperature-dependent phase transitions in the range from 3 K to 300 K using neutron powder diffraction and synchrotron X-ray diffraction. Special emphasis is put on the influence of deuteration on formamidinium, its position in the unit cell and disordering in comparison to fully hydrogenated FAPbBr3. The temperature-dependent measurements show that deuteration critically influences the crystal structures, i.e. results in partially-ordered temperature-dependent structural modifications in which two symmetry-independent molecule positions with additional dislocation of the molecular centre atom and molecular angle inclinations are present.Electrical and thermal transport controlled by growth mode can be used to optimize thermoelectric properties of ZnOAl films, which was adjusted by the re-evaporation of Zn and Al via substrate temperatures. The growth modes include equiaxed crystal, columnar crystal and coexistence of both crystals. In the ZnOAl film, equiaxed crystals improve the carrier mobility and reduce the lattice thermal conductivity. Thus, the carrier mobility and thermal conductivity are tuned by the ratio of equiaxed crystals to columnar crystals. The carrier mobility is dependent on the growth-mode-related defects of oxygen vacancies, zinc interstitials and the substitutional dopant of Al. Improved thermoelectric properties with a power factor of 198.45 µW m-1 K-2 at 510 K were achieved. This study presents a film with the structure of an equiaxed-crystal buffer layer to enhance its thermoelectric properties.In the crystal structures of methylated cyclopentadienyl (Cp) complexes (****, Me4Cp and Me5Cp) deposited in the Cambridge Structural Database, certain orientation types of stacked contacts can be noted as the most frequent. These orientation preferences can be well explained by the matching of oppositely charged regions of electrostatic potential. https://www.selleckchem.com/products/Bafetinib.html Parallel displaced stacking, large offset stacking and C-H...π interactions are the dominant interaction types that are responsible for the arrangement in the crystal structures of stacked methylated Cp complexes.
This observation may be key for the future crystal engineering of heterocyclic chalcones for pharmaceutical applications.Controversy in the description/identification of so-called intermediate phase(s) in PbHfO3, stable in the range ∼420-480 K, has existed for a few decades. A synchrotron diffraction experiment on a partially detwinned crystal allowed the structure to be solved in the superspace group Imma(00γ)s00 (No. 74.2). In contrast to some previously published reports, in the pure compound only one distinct phase was observed between Pbam PbZrO3-like antiferroelectric and Pm3m paraelectric phases. The modulation vector depends only slightly on temperature. The major structure modulation is associated with the displacement of lead ions, which is accompanied by a smaller amplitude modulation for the surrounding O atoms and tilting of HfO6 octahedra. Tilting of the octahedra results in a doubling of the unit cell compared with the parent structure.Crystals of the first synthetic copper tellurite arsenate, CuII5(TeIVO3)2(AsVO4)2 [systematic name pentacopper(II) bis-oxotellurate(IV) bis-oxoarsenate(V)], were grown by the chemical vapour transport method and structurally determined using single-crystal X-ray diffraction. CuII5(TeIVO3)2(AsVO4)2 possesses a novel structure type including a new topological arrangement of CuII and O atoms. CuII5(TeIVO3)2(AsVO4)2 is formed from a framework of two types of Jahn-Teller distorted [CuIIO6] octahedra (one of which is considerably elongated) and [CuIIO5] square pyramids, which are linked by edge-sharing to form chains and dimers and by corner-sharing to complete a three-dimensional framework. [AsVO4] tetrahedra and [TeIVO5] polyhedra bridge the edges of channels along the a-axis direction, with void space remaining for the TeIV stereoactive 5s2 lone pairs. A comparison is made between the crystal structure of CuII5(TeIVO3)2(AsVO4)2 and those of known compounds and minerals, in particular fumarolitic Cu minerals.The effects of temperature (100-370 K) and pressure (0-6 GPa) on the non-localized two-electron multicentric covalent bonds (`pancake bonding') in closely bound radical dimers were studied using single-crystal X-ray diffraction on a 4-cyano-N-methylpyridinium salt of 5,6-dichloro-2,3-dicyanosemiquinone radical anion (DDQ) as the sample compound.
