igniarius. Taken together, these results demonstrate a potential anti-inflammation bioactivity of P. igniarius in vitro, providing a basis for further in vivo research for the prevention and treatment of gout.Transitional cell carcinoma (TCC), also known as urothelial carcinoma, is the most common bladder cancer in humans and dogs. Approximately one-quarter of human TCCs are muscle-invasive and associated with a high risk of death from metastasis. Canine TCC (cTCC) tumours are typically high-grade and muscle-invasive. Shared similarities in risk factors, histopathology, and clinical presentation suggest that cTCC may serve as a model for the assessment of novel therapeutics that may inform therapies for human muscle-invasive TCC. The goal of this study was to characterize cTCC at the molecular level to identify drivers of oncogenesis and druggable targets. We performed whole exome sequencing (WES) of 11 cTCC tumours and three matched normal samples, identifying 583 variants in protein-coding genes. The most common variant was a V-to-E missense mutation in BRAF, identified in 4 out of 11 samples (36%) via WES. Sanger sequencing identified BRAF variants in 8 out of the same 11 cTCC samples, as well as in 22 out of 32 formalin-fixed paraffin embedded (FFPE) cTCC samples, suggesting an overall prevalence of 70%. RNA-Seq was performed to compare the gene expression profiles of cTCC tumours to normal bladder tissue. cTCC tumours exhibited up-regulation of genes involved in the cell cycle, DNA repair, and antiviral immunity. We also analysed the immune landscape of cTCC using immune gene signatures and immunohistochemical analysis. A subset of tumours had characteristics of a hot tumour microenvironment and exhibited high expression of signatures associated with complete response to PD-1/PD-L1 blockade in human bladder cancer.
  Antioxidants are widely used in cosmetic products as they have beneficial effects on skin and prevent skin from harmful effects of environment.  https://www.selleckchem.com/products/blu-451.html  Albizia lebbeck has a significant potential to be used in cosmeceuticals due to its antioxidant activity.
 
  The aim of this study was to formulate a stable and effective o/w emulsion-based emulgel containing Albizia lebbeck bark extract, which have considerable antioxidant activity.
 
  Antioxidant activity of Albizia lebbeck bark extract was determined by DPPH (2,2-diphenyl-1-picrylhydrazyl) method. Emulgel containing 3% extract was developed by mixing o/w emulsion in Carbopol gel along with a placebo emulgel without extract (base). In vitro evaluation of these emulgels, that is, liquefaction, color, phase separation, centrifugation, and pH change were carried out for a period of 8weeks at different storage conditions, that is, 8ºC, 25ºC, 40ºC, and 40ºC & 75% relative humidity (RH). In vivo evaluation of emulgels was carried out on 13healthy female volunteers by measuring various parameters of skin, that is, melanin level, erythema level, moisture content, sebum content, and elasticity at regular time intervals after applying emulgel (both base and test formulation) for 8weeks.
 
  Antioxidant activity of Albizia lebbeck bark extract was 84.7%. Both emulgels (base and test formulation) were stable at all storage conditions. Statistical analysis showed that test formulation produced significant effects (p<0.05) on melanin, erythema level, moisture content, sebum level, and elasticity of skin.
 
  It can be concluded that a stable topical emulgel containing 3% Albizia lebbeck bark extract has significant antioxidant effects on human skin.

  This study aimed to compare the longitudinal change of the psychological distress of healthcare workers (HCWs) with non-HCWs during the repeated outbreaks of the COVID-19 in Japan.
 
  The data were retrieved from the Employee Cohort Study in the Covid-19 pandemic in Japan study. An online survey was conducted on March 2020 (T1), on May 2020 (T2), on August 2020 (T3), and on November 2020 (T4). Psychological distress was measured by the Brief Job Stress Questionnaire. A mixed-model repeated-measures ANOVA was conducted as an indicator of the group differences.
 
  A total sample of analysis was n=996 (HCWs, n=111; non-HCWs, n=885). HCWs consisted of physicians/nurses/midwives and other HCWs (eg, pharmacists, clinical laboratory technicians) in the clinical settings (n=19; 17% and n=61; 55%, respectively), and HCWs not working in the clinical settings (n=31; 28%). Being HCWs were associated with a significant increase in psychological distress from T1 to T2, T3 and T4 (P=.001, P=.002, P<.001; respectively).
 
  The mental health of HCWs deteriorated through the COVID-19 outbreaks compared with non-HCWs. HCWs are continuously the important targets to provide mental health support.

Thus, the realization of anti-Markovnikov (AM) selectivity in these reactions is challenging. This account focuses on our recent development of Pd-catalyzed AM oxidation of terminal alkenes (mainly styrenes and aliphatic alkenes), that is, oxidative acetalization (oxidation to terminal acetals) and Wacker-type oxidation (oxidation to aldehydes). The key factors that enhance the yield and AM selectivity of the products found in our studies are 1) the steric bulkiness of the oxygen nucleophiles that attack on the coordinated alkenes, 2) the electron-deficient cyclic alkenes as additives that withdraw electrons from Pd, 3) the slow addition of substrates in the case of the aliphatic alkenes, which suppresses the isomerization of the terminal alkenes into internal alkenes, and 4) the halogen directing groups in the case of aliphatic alkenes.
  One of the most common forms of post-transplant tubulopathy is hyperkalemic (RTA). The true incidence of hyperkalemic RTA in pediatric patients has not yet been studied. (CNIs) remain mostly blamed. Most cases are managed with sodium bicarbonate and potassium binding resins. Few studies have addressed the role of fludrocortisone in managing such patients. This study aimed to assess the efficacy and safety of fludrocortisone in the treatment of post-transplant hyperkalemic RTA.
 
  This is a retrospective cohort study of all pediatric (aged ≤16years) post-kidney transplant patients who were followed up in KFSH-D, Saudi Arabia from January 2015 until September 2019. A total of 136 pediatric post-renal transplant patients were reviewed, of these, 39 patients who were commenced on fludrocortisone post-transplant treatment and were followed up for at least 6months after fludrocortisone initiation were included in this study.
 
  The incidence of hyperkalemic RTA in our center was 60.6%. The medication requirements decreased significantly after fludrocortisone initiation.
