We performed a meta-analysis to provide quantitative estimates of fat mass (FM) and fat-free mass (FFM) changes in patients following bariatric surgery over 1 year. A systematic search of PubMed, SCOPUS and Web of Science databases was conducted; the pooled weighted mean difference (WMD) and 95% confidence intervals (CI) were calculated using a random-effects model. Thirty-four studies including Roux en-Y gastric bypass (RYGB), sleeve gastrectomy (SG) biliopancreatic diversion (BPD) and gastric banding (GB) were analyzed. RYGB decreased in body FM (-28.99 kg [31.21, -26.77]) or FM% (-12.73% [-15.14, -10.32]) or FFM (-9.97 kg [-10.93, -9.03]), which were greater than SG and GB. Moreover, the FFM% in RYGB group (11.72% [7.33, 16.11]) was more than SG (5.7% [4.44, 6.95]) and GB (8.1% [6.15, 10.05]) groups. Bariatric surgeries, especially RYGB, might be effective for a decrease in FM and maintenance of FFM in patients with morbid obesity in over 1 year.Glycogen synthase kinase 3β (GSK-3β) is involved in a variety of diseases such as neurodegenerative diseases, bipolar disorder, and diabetes. In this study, a series of heterobifunctional small molecule proteolysis targeting chimera (PROTAC) were designed and synthesized based on E3 ubiquitin ligase cereblon (CRBN). Most of PROTACs displayed good inhibitory activity, with the IC50 values at the double-digits nanomolar levels and moderate protein degradation ability against GSK-3β. Western-blot data showed compound PG21 can effectively degrade GSK-3β in a dose-dependent manner, which can induce 44.2% protein degradation at 2.8 μM. Further pharmacological experiments revealed that the ability of PG21 to degrade GSK-3β is mediated by the ubiquitin-proteasome system (UPS). selleck chemicals In addition, PG21 protects against glutamate-induced cell death in HT-22 cells. As the first PROTAC example to degrade GSK-3β protein, the present study has provided potential candidates for further investigation in the biological function of GSK-3β protein and its association with diseases.Salidroside [(2R,3S,4S,5R,6R)-2-(hydroxymethyl)-6-(4-hydroxyphenethoxy)tetrahy-dro-2H-pyran-3,4,5-triol] is an antioxidant, anti-inflammatory and neuroprotective agent, but its drug-like properties are unoptimized and its mechanism of actions is uncertain. We synthesized twenty-six novel derivatives of salidroside and examined them in CoCl2-treated PC12 cells using MTT assay. pOBz, synthesized by esterifying the phenolic hydroxyl group of salidroside with benzoyl chloride, was one of five derivatives that were more cytoprotective than salidroside, with an EC50 of 0.038 μM versus 0.30 μM for salidroside. pOBz was also more lipophilic, with log P of 1.44 versus -0.89 for salidroside. Reverse virtual docking predicted that pOBz would bind strongly with monoamine oxidase (MAO) B by occupying its entrance and substrate cavities, and by interacting with the inter-cavity gating residue Ile199 and Tyr435 of the substrate cavity. Enzymatic studies confirmed that pOBz competitively inhibited the activity of purified human MAO-B (Ki = 0.041 μM versus Ki = 0.92 μM for salidroside), and pOBz was highly selective for MAO-B over MAO-A. In vivo, pOBz inhibited cerebral MAO activity after middle cerebral artery occlusion with reperfusion in rats, and it reduced cerebral infarct volume, improved neurological function and NeuN expression, and inhibited complement C3 expression and apoptosis. Our results suggest that pOBz is a structurally novel type of competitive and selective MAO-B inhibitor, with potent neuroprotective properties after cerebral ischemia-reperfusion injury in rats.Covalent drugs play corresponding bioactivities by forming covalent bonds with the target, which possess many significant pharmacological advantages including high potency, ligand efficiency, and long-lasting effects. However, development of covalent inhibitors is a challenge due to their presumed indiscriminate reactivity. Here, we report the discovery of series of lysosome-targeting covalent anticancer agents by introducing nitrogenous bases to the modified isosteviol skeleton in order to minimize the toxicity and increase the selectivity. By introducing the electrophilic α, β-unsaturated ketones into the A- and D-rings of isosteviol, the cytotoxicity of the obtained compounds were greatly increased. Further nitrogen-containing modifications to the D-ring led to the discovery of novel molecules that targeted lysosomes, and of which, compound 30 was the most potent and selective antiproliferative one to kill A549 cells in vitro and in vivo. Mechanism investigation revealed that compound 30 was trapped into lysosomes and damaged lysosomes to cause cell death.Omega-3-fatty-acids are now increasingly being used for potential beneficial anti-inflammatory effect in the treatment and management of cardiovascular disease. Eicosapentaenoic acid and Docosahexaenoic acid are 2 essential omega-3 fatty acids found predominately in fish and fish oil supplements. Despite the increased use of fish oil products for both primary and secondary prevention of cardiovascular morbidity and mortality, the available literature evidence are controversial. We searched through PubMed for studies that have investigated the impact of omega-3 fatty acids on coronary heart disease and mortality. Our systemic review suggests that most studies, which are mostly observational, have found there to be a potential benefit of omega-3 fatty acids on coronary heart disease whereas some other studies have found conflicting results. More randomized controlled studies are warranted with adequate sample size to clearly establish the risk and benefits of omega-3 fatty acids on cardiovascular disease.
Chest computed tomography (CT) scan is frequently used in the diagnosis of COVID-19 pneumonia.

This study investigates the predictive value of CT severity score (CSS) for length-of-stay (LOS) in hospital, initial disease severity, ICU admission, intubation, and mortality.

In this retrospective study, initial CT scans of consecutively admitted patients with COVID-19 pneumonia were reviewed in a tertiary hospital. The association of CSS with the severity of disease upon admission and the final adverse outcomes was assessed using Pearson's correlation test and logistic regression, respectively.

Total of 121 patients (60±16 years), including 54 women and 67 men, with positive RT-PCR tests were enrolled. We found a significant but weak correlation between CSS and qSOFA, as a measure of disease severity (r 0.261, p=0.003). No significant association was demonstrated between CSS and LOS. Patients with CSS>8 had at least three-fold higher risk of ICU admission, intubation, and mortality.

CSS in baseline CT scan of patients with COVID-19 pneumonia can predict adverse outcomes and is weakly correlated with initial disease severity.
