Structural Characterization and Antioxidant Activity of Polysaccharides from (Doll.) Ching in d-Galactose-Induced Aging Mice via PI3K/AKT Pathway.

Unlabelled: The purpose of this study was to characterize the polysaccharides from (Doll.) Ching (AMC) rhizome and explore the protective mechanism against d-galactose-induced oxidative stress in aging mice.

Methods: A series of experiments, including molecular weight, monosaccharide composition, Fourier transform infrared (FT-IR) spectroscopy, and H nuclear magnetic resonance (H NMR) spectroscopy were carried out to characterize AMC polysaccharides.

Striatisporolide A, a butenolide metabolite from Athyrium multidentatum (Doll.) Ching, as a potential antibacterial agent.

The present study aimed to investigate the antibacterial activity of striatisporolide A (SA) against Escherichia coli (E. coli) and the underlying mechanism. Antibacterial activity was evaluated according to the inhibitory rate and zone of inhibition.

The association between COMT Val158Met polymorphism and migraine risk: A meta-analysis.

Background The COMT Val158Met polymorphism has long been regarded as a risk factor for migraine. The possible association between COMT Val158Met polymorphism and migraine has been evaluated in several studies, but the results are not consistent. Therefore, we conduct this meta-analysis to address these issues.

Does HBV infection increase risk of endometrial carcinoma?

Objective: Connections between chronic inflammation and tumor development and progression are now generally accepted. Recent evidence indicates that hepatitis B is associated with several types of cancer, but whether endometrial carcinoma (EC) is included has not been reported.

Methods: We analyzed HBV serum marker status in 398 patients with endometrial cancer, comparing them to 788 control women undergoing health examination.
