Defecation after magnesium supplementation enhances cognitive performance in triathletes.

Constipation is correlated with diminished cognitive function, revealing a possible rectum-brain connection. In this counter-balanced crossover trial, 13 elite triathletes underwent a Stroop test to assess cognitive function and executive control. The Stroop test was conducted both with and without magnesium oxide intake, with a 1-week washout period between sessions.

Dual Photoredox and Copper-Catalyzed Asymmetric Remote C(sp)-H Alkylation of Hydroxamic Acid Derivatives with Glycine Derivatives.

Dual photoredox and copper-catalyzed remote asymmetric C(sp)-H alkylation of hydroxamic acid derivatives with glycine derivatives via a 1,5-hydrogen transfer (1,5-HAT) process has been realized. The reaction was characterized by redox-neutral and mild conditions, good yields, excellent enantioselectivity, and broad substrate scope. This protocol provides a straightforward and efficient strategy to prepare highly valuable enantioenriched noncanonical α-amino acids.

Combined transcriptomic and metabolomic analyses reveal the pharmacognostic mechanism of the metabolism of flavonoids in different parts of Polygonum capitatum.

The plant Polygonum capitatum (P. capitatum) contains a variety of flavonoids that are distributed differently among different parts. Nevertheless, differentially expressed genes (DEGs) associated with this heterogeneous distribution have not been identified.

Characterization, physicochemical properties, antioxidant activity and hypolipidemic activities of a polysaccharides from Lachnum YM40.

LEP-1a, a new polysaccharide fraction isolated and purified from Lachnum YM40, has a molecular weight of 24.29 kDa. LEP-1a's chemical composition investigation showed that mannose, galactose, and glucose made up the majority of its cosmetics.

A Nitrate/Nitrite Biosensor Designed with an Antiterminator for Diagnosis of Colitis Based on .

is a common microorganism in the human gut that has been linked to health benefits. Furthermore, it is an emerging synthetic biology chassis with the potential to be modified into diagnostic or therapeutic engineered probiotics. However, the absence of biological components limits its further applications.
