Background: Pit mud (PM) hosts diverse microbial communities, which serve as a medium to impart flavor and quality to Baijiu and exhibit long-term tolerance to ethanol and acids, resulting in a unique ecosystem. However, the ecology and metabolic functions of PM remain poorly understood, as many taxa in PM represent largely novel lineages. In this study, we used a combination of metagenomic analysis and chemical derivatization LC-MS analysis to provide a comprehensive overview of microbial community structure, metabolic function, phylogeny, horizontal gene transfer, and the relationship with carboxyl compounds in spatiotemporal PM samples.

For plant diseases to become established, plant pathogens require not only virulence factors and susceptible hosts, but also optimal environmental conditions. The accumulation of high soil salinity can have serious impacts on agro-biological ecosystems. However, the interactions between plant pathogens and salinity have not been fully characterized.

Under NaHCO stress, exogenous 24-epibrassinolide (EBR) markedly alleviated Na accumulation in cucumber plants, thereby decreasing the Na/K, Na/Mg, and Na/Ca ratios. This mitigation was accompanied by elevated concentrations of K, Ca, and Mg, as well as enhanced expression of the and genes. In addition, the activities of plasma membrane H-ATPase, vesicular membrane H-ATPase, and vesicular membrane H-PPase were significantly increased, contributing to the maintenance of ionic balance in cucumber plants.

Objective: To assess, clinically and instrumentally, the efficacy of a stabilized 12% Vitamin C (VC)-based serum (pH 6) on skin photoageing of women of various age and phototype.
Materials And Methods: Eighty women, with Phototypes I to VI, of various age (45-70y) living in Mauritius, participated in an open, uncontrolled study. After a two-week period of washout, they applied the Vitamin C-based serum twice a day for 2 months onto their whole face as well as a hydrating cream every evening to ensure a comparable skin hydration level in all subjects.
Prior thermal acclimation gives White Sturgeon a fin up dealing with low oxygen.

Assessing how at-risk species respond to co-occurring stressors is critical for predicting climate change vulnerability. In this study, we characterized how young-of-the-year White Sturgeon () cope with warming and low oxygen (hypoxia) and investigated whether prior exposure to one stressor may improve the tolerance to a subsequent stressor through "cross-tolerance". Fish were acclimated to five temperatures within their natural range (14-22°C) for one month prior to assessment of thermal tolerance (critical thermal maxima, CTmax) and hypoxia tolerance (incipient lethal oxygen saturation, ILOS; tested at 20°C).
