Long noncoding RNA Gm4419 promotes mesangial cell proliferation and extracellular matrix accumulation the miR-455-3p/histone deacetylase 2 axis.

Long noncoding RNAs may function as competitive endogenous RNAs by sponging microRNAs, thereby contributing to the progression of diabetic nephropathy. In this study, a potential diabetic nephropathy-related long noncoding-microRNA-mRNA axis, Gm4419-miR-455-3p-, was predicted using bioinformatics methods. To verify the role of the Gm4419-miR-455-3p- axis in diabetic nephropathy, an high glucose-induced mesangial cell model was established.

A new class of natural anthelmintics targeting lipid metabolism.

Parasitic helminths are a major global health threat, infecting nearly one-fifth of the human population and causing significant losses in livestock and crops. Resistance to the few anthelmintic drugs is increasing. Here, we report a set of avocado fatty alcohols/acetates (AFAs) that exhibit nematocidal activity against four veterinary parasitic nematode species: Brugia pahangi, Teladorsagia circumcincta and Heligmosomoides polygyrus, as well as a multidrug resistant strain (UGA) of Haemonchus contortus.

Atractylodin mitigates UVB radiation-induced oxidative stress and photoaging responses by enhancing NrF2 signaling in human epidermal keratinocytes.

This study explores the protective role of Atractylodin (ATN) on ultraviolet-B (UVB) radiation-exposed oxidative damage and photoaging responses in human epidermal keratinocytes (HaCaT). In vitro, experiments involved subjecting HaCaT cells to UVB radiation (50 mJ/cm) for a 24 h incubation period, leading to cell death, increased reactive oxygen species (ROS), and DNA damaged lesion (8-Oxo Gunosine). ATN treatment effectively mitigated cell toxicity, ROS generation, and 8-Oxo Gunosine in UVB-exposed HaCaT cells.

Quorum sensing signals of the grapevine crown gall bacterium, sp. Rr2-17: use of inducible expression and polymeric resin to sequester acyl-homoserine lactones.

Background: A grapevine crown gall tumor strain, sp. strain Rr2-17 was previously reported to accumulate copious amounts of diverse quorum sensing signals during growth. Genome sequencing identified a single luxI homolog in strain Rr2-17, suggesting that it may encode for a AHL synthase with broad substrate range, pending functional validation.

Continuous Glucose Monitoring Underreports Blood Glucose During a Simulated Ultraendurance Run in Eumenorrheic Female Runners.

Purpose: Continuous-glucose-monitoring (CGM) sensors provide near-real-time glucose data and have been introduced commercially as a tool to inform nutrition decisions. The aim of this pilot study was to explore how factors such as the menstrual phase, extended running duration, and carbohydrates affect CGM outcomes among trained eumenorrheic females in an outdoor simulated ultraendurance running event.

Methods: Twelve experienced female ultrarunners (age 39 [6] y) participated in this crossover study.
