https://www.selleckchem.com/products/Bleomycin-sulfate.html To compare the safety and efficiency of atherectomy plus drug-coated balloon with drug-coated balloon only for the treatment of femoropopliteal artery lesions. This systematic review and meta-analysis was performed and reported following the requirement of the PRISMA. EMBASE, MEDLINE, and Cochrane library were queried from January 2000 to June 2020 to identify eligible literature. The modified Downs and Black checklist was used to assess the quality of included studies. Outcome measures included bail-out stenting, distal embolization, perforation, hematoma, primary patency at 12 months, target lesion revascularization at 12 months, leg amputation at 12 months, and mortality at 12 months. We used DerSimonian and Laird random-effects model to pool the dichotomous data on risk ratio (RR) with 95% confidence intervals (CIs) from each study to obtain an overall estimate for major outcomes. Subgroup analysis and sensitivity analyses were conducted. Six studies (two randomized controlled trials and four retros safe and effective in the treatment of femoropopliteal artery lesions, with lower incidence of bail-out stenting compared with drug-coated balloon only.Aging is strongly correlated with several noncommunicable disorders such as diabetes, obesity, cardiovascular disease, and neurodegenerative conditions. Glucosamine (2-amino-2-deoxy-d-glucose, GlcN) is a naturally occurring amino sugar and is reported to act as a caloric restriction mimetic (CRM). In young and d-galactose-induced accelerated rat aging models, we tested a persistent oral dietary dose of GlcN and evaluated various aging biomarkers in erythrocytes and plasma. A significant increase in the reactive oxygen species (ROS) was observed in GlcN-treated young and accelerated senescent rat model. Increased value of ferric reducing ability of plasma (FRAP), superoxide dismutase, catalase, and plasma membrane redox system (PMRS) was observed. We suggest t
