We describe a new species of from southern Yunnan, China and northern Vietnam based on morphological and molecular evidence. , which had been recorded as , is the sister to . The new species differs genetically from by 4.2% and 10.7% in 16S rRNA and COI genes, respectively, and it can be morphologically distinguished from by having more densely spaced white warts on the dorsal surface, red subarticular tubercles, red metacarpal tubercles, a red metatarsal tubercle, and black dorsal and ventral surfaces in preservative. Currently the new species is only known from the China-Vietnam border regions of Yunnan and Ha Giang, while has a wide distributional range in China including Guangxi, Guangdong, Hunan, Fujian, Jiangxi, and presumably Guizhou and eastern Yunnan. Including the new species, there are currently 10 species in China and seven species in Yunnan, where more species will probably be found.

Context: The decline in ovarian reserve is a major concern in female reproductive health, often associated with oxidative stress and mitochondrial dysfunction. Although ginsenoside Rg1 is known to modulate mitophagy, its effectiveness in mitigating ovarian reserve decline remains unclear.

Objective: To investigate the role of ginsenoside Rg1 in promoting mitophagy to preserve ovarian reserve.

Phytochemical composition, antioxidant and antimicrobial activities of Delile ex Godr flowers extracts.

Nat Prod Res

January 2025

Laboratory of Organic Chemistry LR17-ES08 (Natural Substances Team), Faculty of Sciences of Sfax, University of Sfax, Sfax, Tunisia.

The phytochemical profile of various plant species reveals that some compounds possess notable antioxidant and antimicrobial properties. In this study we investigated for the first time, the antioxidant activity (FRAP, DPPH and TAC), total phenolic contents and total flavonoid contents of Delile ex Godr flowers extracts (-hexane, ethyl acetate and methanol) as well as their antimicrobial activity. The results obtained showed that the methanol extract contained the highest content of total phenolics (346.

Mitochondria as a Therapeutic Target: Focusing on Traumatic Brain Injury.

J Integr Neurosci

January 2025

Department of Hepatology, Federal University of Health Sciences of Porto Alegre (UFCSPA), 90050-170 Porto Alegre, Rio Grande do Sul (RS), Brazil.

Mitochondria are organelles of eukaryotic cells delimited by two membranes and cristae that consume oxygen to produce adenosine triphosphate (ATP), and are involved in the synthesis of vital metabolites, calcium homeostasis, and cell death mechanisms. Strikingly, normal mitochondria function as an integration center between multiple conditions that determine neural cell homeostasis, whereas lesions that lead to mitochondrial dysfunction can desynchronize cellular functions, thus contributing to the pathophysiology of traumatic brain injury (TBI). In addition, TBI leads to impaired coupling of the mitochondrial electron transport system with oxidative phosphorylation that provides most of the energy needed to maintain vital functions, ionic homeostasis, and membrane potentials.

Genetic and species rearrangements in microbial consortia impact biodegradation potential.

ISME J

January 2025

Universidad Pablo de Olavide, Centro Andaluz de Biología del Desarrollo/ Consejo Superior de Investigaciones Científicas/ Junta de Andalucía, Seville, Spain.

Genomic reorganisation between species and horizontal gene transfer have been considered the most important mechanism of biological adaptation under selective pressure. Still, the impact of mobile genes in microbial ecology is far from being completely understood. Here we present the collection and characterisation of microbial consortia enriched from environments contaminated with emerging pollutants, such as non-steroidal anti-inflammatory drugs.
