Moderate- and High-Speed Treadmill Running Exercise Have Minimal Impact on Rat Achilles Tendon.

Exercise influences clinical Achilles tendon health in humans, but animal models of exercise-related Achilles tendon changes are lacking. Moreover, previous investigations of the effects of treadmill running exercise on rat Achilles tendon demonstrate variable outcomes. Our objective was to assess the functional, structural, cellular, and biomechanical impacts of treadmill running exercise on rat Achilles tendon with sensitive in and ex vivo approaches.

Histone Deacetylase 9 Deletion Inhibits Hepatic Steatosis and Adipose Tissue Inflammation in Male Diet-Induced Obese Mice.

Aim: The goal of this study was to determine the role of histone deacetylase 9 (HDAC9) in the development of diet-induced metabolic dysfunction-associated steatohepatitis (MASH) and white adipose tissue (WAT) dysfunctions.

Effect of a Mating Type Gene Editing in Using RNP/Nanoparticle Complex.

Gene editing using CRISPR/Cas9 is an innovative tool for developing new mushroom strains, offering a promising alternative to traditional breeding methods that are time-consuming and labor-intensive. However, plasmid-based gene editing presents several challenges, including the need for selecting appropriate promoters for Cas9 expression, optimizing codons for the Cas9 gene, the unintended insertion of fragmented plasmid DNA into genomic DNA (gDNA), and regulatory concerns related to genetically modified organisms (GMOs). To address these issues, we utilized a Ribonucleoprotein (RNP) complex consisting of Cas9 and gRNA for gene editing to modify the A mating-type gene of .

The Beneficial Roles of Seaweed in Atopic Dermatitis.

Atopic dermatitis (AD) is a chronic, inflammatory skin condition characterized by severe pruritus and recurrent flare-ups, significantly impacting patients' quality of life. Current treatments, such as corticosteroids and immunomodulators, often provide symptomatic relief but can lead to adverse effects with prolonged use. Seaweed, a sustainable and nutrient-dense resource, has emerged as a promising alternative due to its rich bioactive compounds-polysaccharides, phlorotannins, polyphenols, and chlorophyll-that offer anti-inflammatory, antioxidant, and immunomodulatory properties.
