[Astragalus polysaccharides improve adipose tissue aging in naturally aged mice via indole-3-lactic acid].

Plant polysaccharides are effective components that widely present in traditional Chinese medicine(TCM), exhibiting rich biological activities. However, as most plant polysaccharides cannot be directly absorbed and utilized by the human digestive system, it is now believed that their mode of action mainly involves interaction with intestinal microbiota, leading to the production of functional small molecules. The efficacy of Astragalus polysaccharide(APS) is extensive, including weight loss, improvement of fatty liver, reduction of blood lipids, and enhancement of insulin sensitivity, which may also be related to the regulation of intestinal microbiota.

Emotion Regulation of Hippocampus Using Real-Time fMRI Neurofeedback in Healthy Human.

Real-time functional magnetic resonance imaging neurofeedback (rtfMRI-NF) is a prospective tool to enhance the emotion regulation capability of participants and to alleviate their emotional disorders. The hippocampus is a key brain region in the emotional brain network and plays a significant role in social cognition and emotion processing in the brain. However, few studies have focused on the emotion NF of the hippocampus.

Relationship between expression of XRCC1 and tumor proliferation, migration, invasion, and angiogenesis in glioma.
