The volitional movement of skeletal is controlled by the motor neuron at the site of neuromuscular junction (NMJ) where the retrograde signals are also passed back from muscle to the motor neuron. As the normal function of muscle largely depends on mitochondria that determine the fate of a skeletal muscle myofiber, there must exist a fine-controlled functional coupling between NMJ and mitochondria in myofibers. This mini-review discusses recent publications that reveal how spatiotemporal profiles of intracellular free Ca could couple mitochondrial function with the activity of NMJ in skeletal muscle myofibers.

Objective: This study aimed to investigate the effects of structured orofacial muscle rehabilitation training (OMRT) on the recovery of facial expression muscles in patients with skeletal Class II malocclusion after orthognathic surgery.
Study Design: This randomized controlled trial enrolled 56 skeletal Class II malocclusion patients who underwent orthognathic surgery. The intervention group received structured OMRT, while the control group received standard postoperative care.

Skeletal muscle alpha actin (ACTA1) is important for muscle contraction and relaxation, with historical studies focused on ACTA1 mutations in muscle dysfunction. Proteomics reports have consistently observed that actin, including ACTA1, is acetylated at multiple lysine sites. However, few reports have studied the effects of actin acetylation on cellular function, and fewer have examined ACTA1 acetylation on skeletal muscle function.

Cognitive decline and physical impairment are often linked with ageing, contributing to declines in health span and loss of independence in older adults. Pathological cognitive decline with age is largely considered to be a brain-centric challenge. However, recent findings have begun to challenge this paradigm as the health of peripheral systems, namely skeletal muscle, predict cognitive decline associated with Alzheimer's disease (AD).

Purpose: Sarcopenia and sarcopenic obesity are defined by the loss of muscle strength and mass. Both diseases pose a growing global challenge. Their prevalences vary between studied populations.

Background: Excessive oxidative stress is well known to participate in the pathogenesis of hypertension. A major regulator of oxidative stress is the transcription factor Nuclear factor erythroid 2-related factor 2 (Nrf2). However, the role of Nrf2 in the pathogenesis of hypertension is not completely understood, especially at the endothelial cell level.
