Fucoidan exerts antitumor effects by regulating gut microbiota and tryptophan metabolism.

Fucoidan, a water-soluble polysaccharide derived from marine organisms, has garnered significant attention for its ability to regulate gut microbiota and its anti-tumor properties. However, the existence of a correlation between the anti-tumor effect of fucoidan and its regulation of the gut microbiota remains unknown. In pursuit of this objective, we culled the gut microbiota of mice with broad-spectrum antibiotics to generate pseudo-sterile tumor-bearing mice.

Photothermal antimicrobial guar gum hydrogel cross-linked by bioactive small molecule lysine for infected wound healing.

The healing of bacteria-infected wounds has long posed a significant clinical challenge. Traditional hydrogel wound dressings often lack self-healing properties and effective antibacterial characteristics, making wound healing difficult.

Isolation and identification of pigeon adenovirus 1 and analysis of its pathogenicity in pigeons and chickens.

Pigeon adenovirus type 1 predominantly infects pigeons under 12 months of age (mainly 3-5 months old), causing major clinical symptoms such as vomiting, dehydration, and discharge of thin yellow feces. In February 2023, an outbreak of a pathogen with symptoms similar to pigeon adenovirus infections occurred on a pigeon farm in Shandong Province, which was eventually identified as pigeon adenovirus type 1. In this study, a strain of PiAdV-1 was isolated from naturally infected pigeons and named pigeon-adenovirus-1-isolate-CH-SD-2023, and the hexon gene sequence as amplified and analyzed using polymerase chain reaction (PCR).

Hexahistidine-metal assembly encapsulated fibroblast growth factor 21 for lipopolysaccharide-induced acute lung injury.

Targeting HNRNPA2B1 to Overcome Chemotherapy Resistance in Gastric Cancer Stem Cells: Mechanisms and Therapeutic Potential.

Gastric cancer (GC) remains a significant global health challenge, particularly due to the resistance of gastric cancer stem cells (GCSCs) to chemotherapy. This study investigates the role of heterogeneous nuclear ribonucleoprotein A2/B1 (HNRNPA2B1), a member of the heterogeneous nuclear ribonucleoproteins (hnRNPs), in modulating mitochondrial metabolic reprogramming and contributing to chemoresistance in GCSCs. Through extensive analysis of tumor cancer genome atlas (TCGA) and gene expression omnibus (GEO) datasets, HNRNPA2B1 was identified as a key regulator in GCSCs, correlating with poor prognosis and enhanced resistance to chemoresistance.

This model could identify DJD as well as the radiographic signs of DJD, namely, erosion, osteophytes, sclerosis and subchondral cysts.

Effect of estrogen on myocardial ischemia-reperfusion injury in male and female rats and related mechanism.

Due to the difference of estrogen levels in different phases of estrous cycle, it is necessary to exclude the influence of endogenous estrogen when studying the cardiovascular effects of estrogen and its analogues. In this study, the ischemia/reperfusion (I/R) injury of isolated heart were investigated in female rats during different phases of estrous cycle with male rats as comparison. The results indicated that the estrogen content in blood of rats during metestrus and diestrus (MD) was lower than those during proestrus and estrous (PE).
