Mn_(3)TeO_(6)(MTO) has been experimentally found to adopt a P2_(1)/In structure under high pressure,which exhibits a significantly smaller band gap compared to the atmospheric R3 *** this study,we systematically investigate the magnetism,structural phase transition,and electronic properties of MTO under high pressure through first-principles *** R3 and P2_(1)/n phases of MTO are antiferromagnetic at zero *** R3 phase transforms to the P2_(1)/n phase at 7.5 8 GPa,accompanied by a considerable volume collapse of about 6.47%.Employing the accurate method that combines DFT+U/and GW,the calculated band gap of R3 phase at zero pressure is very close to the experimental values,while that of the P2_(1)/n phase is significantly *** main reason for this difference is that the experimental study incorrectly used the Kubelka-Munk plot for the indirect band gap to obtain the band gap of the P2_(1)/n phase instead of the Kubelka-Munk plot for the direct band ***,our study reveals that the transition from the R3 phase to the P2_(1)/n phase is accompanied by a slight reduction in the band gap.

Lactic acid bacteria act as potent interventions in improving hyperuricemia: a review

引用

Food Science and Human Wellness 2024年

作者： qing-Ling Wu Xiao-Dong Pei Tian-Tian Gao Xiao-Ling Liu Cheng-hua Wang College of Light Industry and Food Engineering， Guangxi University

Hyperuricemia (hua) is characterized by elevated levels of uric acid (UA) in the bloodstream， resulting from either excessive production or insufficient excretion of UA within the body. If left untreated， progressive or persistent hua can lead to gout， causing significant harm to human health. Lactic acid bacteria (LAB)， generally recognized as safe (GRAS) probiotics， have been shown to alleviate symptoms associated with gastrointestinal disorders such as irritable bowel syndrome and inflammatory bowel disease while supporting overall bodily functions and health. Recently， LAB has emerged as a potentially safe， cost-effective and efficient treatment for hua. This comprehensive review aims to explore the current literature on the mechanisms through which LAB controls hua. These mechanisms include suppressing purine metabolism， absorbing purine compounds， modulating microbiota to maintain host global purine homeostasis， reducing intestinal permeability， producing metabolites that alleviate hua symptoms， promoting the expression of urate excretory proteins and inhibiting the expression of urate reabsorption proteins. The findings presented in this review provide a framework for further investigation into how probiotic LAB can alleviate hua by influencing UA metabolism and elucidating their underlying action mechanisms.
