Anatomy of the distal tendinous structure of the triceps brachii: implications for the role of the triceps brachii to resist valgus elbow forces during baseball pitching.

Department of Clinical Anatomy, Graduate School of Medical and Dental Science, Tokyo Medical and Dental University, Tokyo, Japan.
Background: Biomechanical studies suggest that the triceps brachii muscle generates resistive force against valgus stress on the elbow during baseball pitching. However, given the parallel fiber orientation in the distal tendinous structure of the triceps brachii, the mechanism behind this anti-valgus force remains unclear. In the present study, we aimed to examine the anatomy of the distal tendinous structure of the triceps brachii using bony morphological, macroscopic, and histological methods.

Alzheimer's disease is a complex neurodegenerative disease characterized by progressive decline in cognitive function and behaviour. Ginger is the rhizome of the plant Zingiber officinale Roscoe, has been an important ingredient of many Ayurveda formulations to treat neurological disorders. The present study aims to estimate the variation of 6-gingerol content in nine different ginger samples collected from Manipur, India, investigate the neuroprotective potential of the most potent ginger sample against scopolamine-induced cognitively impaired mice, and validate the therapeutic claim by molecular docking analysis.

Background: Duchenne muscular dystrophy (DMD) is a prevalent, fatal degenerative muscle disease with no effective treatments. Mdx mouse model of DMD exhibits impaired muscle performance, oxidative stress, and dysfunctional autophagy. Although antioxidant treatments may improve the mdx phenotype, the precise molecular mechanisms remain unclear.

However, the cellular mechanisms regulating GEC fenestrations remain poorly understood due to limitations in existing models, challenges in imaging small fenestrations , and inconsistencies between and findings. This study used a logic-based protein-protein interaction network model with normalized Hill functions for dynamics to explore how glucose-mediated signaling dysregulation impacts fenestration dynamics in GECs.

Decellularized artificial blood vessels prepared using physical and chemical methods often exhibit limitations, including poor mechanical performance, susceptibility to inflammation and calcification, and reduced patency. Cross-linking techniques can enhance the stiffness, as well as anti-inflammatory and anti-calcification properties of decellularized vessels. However, conventional cross-linking methods fail to effectively alleviate residual stress post-decellularization, which significantly impacts the patency and vascular remodeling following the implantation of artificial vessels.
