Astragaloside IV inhibits retinal pigment epithelial cell senescence and reduces IL-1β mRNA stability by targeting FTO-mediated mA methylation.

Background: Resistance to senescence in retinal pigment epithelial (RPE) cells can delay the progression of age-related macular degeneration (AMD). However, the mechanisms underlying RPE cell senescence remain inadequately understood, and effective therapeutic strategies are lacking. While astragaloside IV (Ast) has demonstrated anti-aging properties, its specific effects on RPE cell senescence and potential mechanisms are not yet fully clarified.

Atlantodentoplasty using the anterior retropharyngeal approach for treating irreducible atlantoaxial dislocation with atlantodental bony obstruction: a retrospective study.

Study Design: This was a retrospective study.

Purpose: The current study aimed to investigate the clinical efficacy of atlantodentoplasty using the anterior retropharyngeal approach against irreducible atlantoaxial dislocation with atlantodental bony obstruction.

Overview Of Literature: In cases of atlantoaxial dislocation with atlantodental bony obstruction, owing to the presence of an osteogenic mass between the atlas and odontoid process, reduction is challenging to complete using the posterior approach.

Injectable hydrogel-assisted local lipopolysaccharide delivery improves immune checkpoint blockade therapy.

Tumor-associated macrophages (TAMs) significantly influence the clinical outcomes of immune checkpoint blockade (ICB) therapy. Strategies aimed at reprogramming TAMs from the immunosuppressive M2 phenotype to the pro-inflammatory M1 phenotype hold promise for enhancing ICB efficacy. Lipopolysaccharide (LPS), a potent Toll-like receptor 4 (TLR4) ligand, can reprogram TAMs toward an M1 phenotype.

Probing the functional constraints of influenza A virus NEP by deep mutational scanning.

The influenza A virus nuclear export protein (NEP) is a multifunctional protein that is essential for the viral life cycle and has very high sequence conservation. However, since the open reading frame of NEP largely overlaps with that of another influenza viral protein, non-structural protein 1, it is difficult to infer the functional constraints of NEP based on sequence conservation analysis. In addition, the N-terminal of NEP is structurally disordered, which further complicates the understanding of its function.

Comparison of average daily gain, apparent digestibility, rumen fermentation parameters and bacterial communities, and serum antioxidant indices in Leizhou goats fed with or without rumen-protected fat.

Introduction: Rumen-protected fat (RPF) is a vital dietary energy source for dairy cows. However, the influences of RPF on rumen volatile fatty acid (VFA) content and bacterial communities in goats are poorly documented.

Methods: In this study, 12 castrated male goats (body weight [BW]: 13.
