Two new phytoecdysteroids isolated from .

Two new phytoecdysteroids, (24)-20,26-dihydroxy-24(28)-dehydro-28-methyl-ecdysone (), (24)-22,25-epoxy-2,3,14,20-tetrahydroxyergosta-7,24(28)-dien-28-methyl-6-one (), together with eleven known compounds (-) were isolated from the whole plant of L. The chemical structures of the compounds were elucidated by 1D and 2D NMR and HR-ESI-MS and compared with data from the literature. The isolated compounds were evaluated for their inhibitory effects on NO, TNF-α and IL-6 production in LPS-induced RAW 264.

Comparison of Inferior Extensor Retinacular Reinforcement Versus Nonreinforcement in Arthroscopic Isolated Anterior Talofibular Ligament Repair for Chronic Lateral Ankle Instability: A Systematic Review and Meta-analysis.

Background: Approximately 20% of acute ankle sprains progress to chronic lateral ankle instability (CLAI), requiring surgical intervention. When only the anterior talofibular ligament (ATFL) is ruptured, it is controversial whether to perform arthroscopic inferior extensor retinacular (IER) reinforcement.

Purpose: To assess the postoperative outcomes of IER reinforcement versus nonreinforcement in arthroscopic treatment of CLAI with ATFL-only injury.

Giant cell tumor of the talus: A case report and literature review.

Introduction And Importance: Giant cell tumor is a benign primary bone tumor of mesenchymal origin that mainly affects the long bones. Involvement of the bones of the foot is rare with an incidence of 1 to 2 %. We report a case of giant cell tumor of the talus in a 36-year-old man.

Deciphering genetic characteristics of South China and North China indigenous pigs through selection signatures.

Background: Indigenous pig breeds in China have accumulated significant genetic diversity due to regional selection pressures. Investigating the selection signatures of these populations helps to understand their adaptive evolution and contributes to genetic improvement programs.

Results: We collected whole-genome sequencing data from 133 individuals, including South China and North China indigenous pigs and Asian wild boars.

Evaluation of the Breed Composition of Pork via Population Structure Analysis in Pigs.

The quality of pork meat directly influences the price and consumption. The genetic improvement of pigs has mainly focused on high productive efficiency, which has resulted in poor meat quality. Crossbreeds containing commercial and indigenous breeds could improve the meat quality, but identifying breed composition was difficult because of the lack of an ancestry reference panel.
