Recent studies demonstrate that adaptations to white adipose tissue (WAT) are important components of the beneficial effects of exercise training on metabolic health. Exercise training favorably alters the phenotype of subcutaneous inguinal WAT (iWAT) in male mice, including decreasing fat mass, improving mitochondrial function, inducing beiging, and stimulating the secretion of adipokines. In this study, we find that despite performing more voluntary wheel running compared with males, these adaptations do not occur in the iWAT of female mice. Consistent with sex-specific adaptations, we report that mRNA expression of androgen receptor coactivators is upregulated in iWAT from trained male mice and that testosterone treatment of primary adipocytes derived from the iWAT of male, but not female mice, phenocopies exercise-induced metabolic adaptations. Sex specificity also occurs in the secretome profile, as we identify cysteine-rich secretory protein 1 (Crisp1) as a novel adipokine that is only secreted from male iWAT in response to exercise. Crisp1 expression is upregulated by testosterone and functions to increase glucose and fatty acid uptake. Our finding that adaptations to iWAT with exercise training are dramatically greater in male mice has potential clinical implications for understanding the different metabolic response to exercise training in males and females and demonstrates the importance of investigating both sexes in studies of adipose tissue biology.The order no. 2010-49 of January 13, 2010 has made the accreditation of medical biology laboratories in France mandatory. It is based on international standards NF EN ISO 15189 for medical biology laboratories and NF EN ISO 22870 for point-of-care testing. The NF EN ISO 151892012 standard is an adaptation of the requirements relating to the quality management system according to the ISO 90012008 standard, to improve delivery performance. As a company's performance is closely linked to its quality culture, the establishment and development of a quality culture within a company appears fundamental. The purpose of this article is to explain how to create a common language on which to base the development of quality culture within a medical biology laboratory. It is a simple approach which consists in asking 3 questions concerning quality management to the members of the team of this laboratory (what do you value? what emotions give you these values? what do you not value?) then to organize the answers in a reference frame for quality management.Sepsis is one of the leading causes of in-hospital mortality. In some patients, sepsis-induced immunosuppression is associated with increased risk of death and secondary infections. In oncology, myeloid-derived suppressor cells (MDSCs) have been described to inhibit various immune functions. Monocytic MDSCs (M-MDSCs) represent a subtype of MDSCs. The objectives of the present study was to determine by flow cytometry the % M-MDSCs (among total monocyte population) in a cohort of septic shock patients and to assess its association with deleterious outcomes 28-day mortality and occurrence of nosocomial infections. The cohort included 301 patients. They presented with immune alterations usually found 3-4 days after the onset of shock lymphopenia (median T CD4 362/μL, quartiles 235-591/μL) and low monocytic HLA-DR expression (median 4,944 AB/C, quartiles 3,104-8,266 AB/C). From admission until the end of the first week, % M-MDSCs was significantly increased in patients compared with healthy donors (p less then 0.01). In early samples, no association with deleterious outcomes was identified. However, after one week, patients who were going to die or to develop nosocomial infections presented with significantly higher % M-MDSCs than non-survivors and non-infected patients (p less then 0.01). These associations remained significant in multivariate analyses, odds ratio of 4.4 (p = 0.001) regarding 28-day mortality and 2.4 (p = 0.013) regarding occurrence of nosocomial infections. In conclusion, % M-MDSCs was markedly increased after septic shock. One week-persistence of an increased proportion of M-MDSCs was associated with unfavorable outcomes.
  The kidney function monitoring is recommended in routine practice to detect 5-aminosalicylic acid (5-ASA) related nephrotoxicity, although is not standardized. The optimal monitoring is unknown, especially the best timing and which tests to perform. We summarized why, how, and when to perform the monitoring for patients treated with 5-ASA and provided an overview of the current guidelines on this topic.
 
  Relevant studies on this topic were searched in PubMed, Embase, and Web of Science databases from July to August 2020.
 
  Serum creatinine, the estimated glomerular filtration rate, and 24-h proteinuria are the 3 main tests used for the monitoring in daily practice. Regarding the timing, several monitoring strategies have been proposed and guidelines are available too, but they provide conflicting information. To date, there is no medical evidence-based that one strategy is better than another. Comorbidities, chronic renal disease, use of nephrotoxic drugs or concomitant steroid therapy also impact the nephrotoxicity risk. Based on the literature review we proposed a kidney function monitoring strategy to guide physicians in clinical practice.
 
  A baseline assessment should be performed in all patients treated with 5-ASA. The monitoring should be carried out according to the other nephrotoxic factors. A tight monitoring may reduce morbidity and mortality of drug nephrotoxicity.

  Hepatocellular carcinoma (HCC) is the most predominant primary liver cancer. Extracellular vesicles (EV)-mediated microRNA (miRNA) delivery is critical in cancer metastasis. We aimed to identify the mechanism of HCC cell-derived EVs-mediated miR-3129 in HCC.
 
  After EVs isolation and identification, miR-3129 expression in plasma EVs was evaluated and its diagnostic efficiency was analyzed. miR-3129 inhibitor was transfected into HepG2 and SMMC7721 cells, and cell malignant episodes were assessed. HCC cells were incubated with EVs from MHCC-97H cells and transfected with miR-3129 inhibitor and/or TXNIP. The nude mice were injected with MHCC-97H cells-EV or MHCC-97H cells-EV/miR-3129 inhibitor, and HCC growth and metastasis were assessed.
 
  miR-3129 was highly expressed in plasma EVs from HCC patients, which was the essential diagnostic biomarker for HCC. miR-3129 downregulation inhibited the malignant episodes of HCC cells. MHCC-97H cell-EVs were absorbed by HCC cells and transferred miR-3129 to HCC cells.  https://www.selleckchem.com/products/lxs-196.html  EVs-carried miR-3129 promoted malignant episodes of HCC cells, which were weakened by miR-3129 inhibition in EVs.
