Transforming growth factor-β (TGF-β) and heat shock protein 70 (HSP70) are important for the hair follicle (HF) cycle, but it is unclear whether they participate in HF regression in yak skin. In this study, we investigated the role of TGF-β, TGF-βRII, and HSP70 in the transition from anagen to catagen of HFs. The results showed that TGF-β2 transcription was significantly higher than that of TGF-β1 and TGF-β3 in the same periods.

The 12 clinically healthy yak tonsils [3- to 6-year old, n = 12] were examined for morphology using light, and transmission electron microscopes. Expression of IgA and IgG was measured by qRT-PCR, ELISA, and immunohistochemistry.

In order to explore the expression profiles of BMP2, BMPR-IA, and Noggin in the HF cycle of yak skin, we collected adult yak skin in the telogen, proanagen, and midanagen phases of HFs and evaluated gene and protein expression by real-time quantitative polymerase chain reaction (qRT-PCR), western blotting, and immunohistochemistry. qRT-PCR and western blotting results showed that BMP2 and BMPR-IA expression levels were highest in the telogen of HFs and higher than that of Noggin in the same phase.

This work reports the synthesis of conductive MOF/CNT composites with enhanced electrochemical reactivity. The growth mechanism of the pristine MOF and the correlations of two components are investigated from the viewpoint of crystal engineering.

Seventeen indolizine derivatives were reported for the first time. All the compounds were examined for their antiproliferative activity against the human hepatocellular liver carcinoma (Hep-G2) cell line by MTT method.

Some of them exhibited significant EGFR and HER-2 inhibitory activity. Compound 2-(2-(5-bromo-2-hydroxybenzylidene)hydrazinyl)thiazol-4(5H)-one (12) displayed the most potent inhibitory activity (IC(50)=0.

Beta-ketoacyl-acyl carrier protein synthase III (FabH) catalyzes the initial step of fatty acid biosynthesis via a type II fatty acid synthase in most bacteria. The important role of this essential enzyme combined with its unique structural features and ubiquitous occurrence in bacteria has made it an attractive new target for the development of antibacterial agents.
