Serum high-density lipoprotein cholesterol levels predict early recurrence and prognosis of intrahepatic cholangiocarcinoma after surgical resection.

Introduction: Dysregulation in lipid metabolism contributes to the occurrence and development of various cancers. The connection between changes in lipid metabolism and the development of intrahepatic cholangiocarcinoma remains uncertain. Our objective was to investigate the significance of blood lipid levels in patients with intrahepatic cholangiocarcinoma who have undergone surgery.

Antioxidant Capacity and Protective Effect of Cow Placenta Extract on D-Galactose-Induced Skin Aging in Mice.

Placental extract has been used for skin care and delaying skin aging. Cow placenta is an abundant resource with a large mass, which has not been harnessed effectively. Cow placenta extract (CPE) has the functions of antioxidation, anti-inflammatory, promoting growth and development, and promoting hair growth.

Effect of anemoside B4 on milk whey in clinical mastitis-affected cows elucidated using tandem mass tag (TMT)-based quantitative proteomics.

Intramuscular injection of anemoside B4 (AB4) has a superior therapeutic effect on clinical mastitis in lactating cows. Here, we explored AB4's effect on milk whey in clinical mastitis-affected cows using proteomics. Among fifty clinical mastitis cows received AB4 administration (0.

The Effect of Mask Wearing on the Accuracy of Radiology Reports in an Academic Hospital Setting.

Purpose: In response to the pandemic, some public health agencies recommend the wearing of surgical masks in indoor spaces including radiology common reporting rooms. We aim to demonstrate whether mask wearing may lead to increased errors incidence in radiology reports.

Materials And Methods: Our prospective studywas conveyed in 2 parts.

Comparative iTRAQ Proteomics Reveals Multiple Effects of Selenium Yeast on Dairy Cows in Parturition.

The effects of prepartum dietary supplementation with selenium yeast on low abundant plasma proteins in postpartum dairy cows are not known. In this study, 24 healthy parturient dairy cows were divided into two groups (group C, a control group, and group T, a selenium treatment group). Low abundance proteins were extracted from plasma samples of calving cows, and 542 proteins were identified by isobaric tags for relative and absolute quantitation (iTRAQ) proteomic analysis.

[Role of Sertoli cells in regulating spermatogenesis: An update].

Spermatogenesis is a complex process in which Sertoli cells play a pivotal role. Sertoli cells are closely related to testicular development and male fertility by providing nutrition for the proliferation of germ cells and maintaining the balance of microenvironment in seminiferous tubules. This article focuses on the roles of Sertoli cells in normal and abnormal spermatogenesis, outlines the association of spermatogenesis with the number and morphology of and protein expressions and secretions in Sertoli cells, and provides some reference for the studies of the gene therapy for male infertility and male contraception.

Genome-wide DNA methylation profile of prepubertal porcine testis.

The biological structure and function of the mammalian testis undergo important developmental changes during prepuberty and DNA methylation is dynamically regulated during testis development. In this study, we generated the first genome-wide DNA methylation profile of prepubertal porcine testis using methyl-DNA immunoprecipitation (MeDIP) combined with high-throughput sequencing (MeDIP-seq). Over 190 million high-quality reads were generated, containing 43642 CpG islands.

[Effects of retinol on expressions of epidermal growth factor, stem cell factor, colony-stimulating factor 1 and leukemia inhibitory factor in human umbilical cord-derived mesenchymal stem cells].

Objective: To investigate effects of retinol on the expressions of epidermal growth factor (EGF), stem cell factor (SCF), colony-stimulating factor 1 (CSF1) and leukemia inhibitory factor (LIF) in cultured human umbilical-derived mesenchymal stem cells (UCMSCs).

Methods: Human UCMSCs were isolated from human umbilical cord and identified for immunophenotypes. The cells were then cultured in DMEM/F12 media supplemented with 12% fetal bovine serum (FBS), 12% FBS+1 µmol/L retinol, 15% knockout serum replacement (KSR) and 15% KSR+ 1 µmol/L retinol.

CRISPR/Cas9 genome editing technique and its application in site-directed genome modification of animals.

CRISPR/Cas system, which uses CRISPR RNAs (crRNAs) to guide Cas nuclease to silence invading nucleic acids, is self-defense system against exogenous virus or plasmid in bacteria and archaea. Through molecular modification, the typeⅡCRISPR/Cas system has become a highly efficient site-directed genome editing technique, which is simpler than zinc-finger nucleases (ZFNs) and transcription activator like effector nucleases (TALENs) and easier to be designed and applied. In this review, we summarize the evolutionary history of CRISPR/Cas9 system, the working principle and modification process of type Ⅱ CRISPR/Cas and its application in animal genome modification.
