Abstract Background Although oocyte quality is the dominant factor determining embryo quality, few studies have been conducted to evaluate based on metabolites related oocyte. With quantification of follicular fluid (FF) metabolites, in assisted reproductive technology (ART), this study sought or through an informative approach. Results An evaluation model consisting 17 features was generated distinguish day 3 post-fertilization, and phosphatidylcholines (PCs) were key contributors...

BACKGROUND Bovine papillomatosis is a type of proliferative tumor disease skin and mucosae caused by bovine papillomavirus (BPV). As transboundary emerging in cattle, it poses potential threat to the dairy industry. OBJECTIVES The aim this study detect clarify genetic diversity BPV circulating cows Xinjiang, China. METHODS 122 papilloma lesions from 8 intensive farms located different regions China were detected polymerase chain reaction. evolution relationships various types BPVs analyzed...

Ebinur Lake Watershed, with its oases and deserts, is a typically arid mountainous region on the northern slope of Tianshan Mountains. Along ever increasing human activities, agricultural domestic wastes have been directly discharged into river systems around which consequently poses grave threat to sustainable development Xinjiang. Through statistical spatial analysis, we determined relationships between land use/cover (LULC) hydro-chemical characteristics during rainy dry seasons in 2014....

Background Hepatitis C virus (HCV) is one of the main causes liver fibrosis, chronic hepatitis, and cirrhosis. The aim this study to determine prevalence HCV, age-dependent genotypes distribution in a large number clinical samples Sichuan area China. Methods In past five years from 2014 2018, total 4,508 individuals received serum HCV-RNA analysis Provincial People's Hospital. Viral nucleic acid was extracted amplified using COBAS AmpliPre/COBAS TaqMan Detection Platform. Five HCV (1b, 2a,...
