Muscle contraction depends on strictly controlled Ca transients within myocytes. A major player maintaining these transients is the sarcoplasmic/endoplasmic reticulum Ca ATPase, SERCA. Activity of SERCA is regulated by binding of micropeptides and impaired expression or function of these peptides results in cardiomyopathy. To date, it is not known how homeostasis or turnover of the micropeptides is regulated. Herein, we find that the Drosophila endopeptidase Neprilysin 4 hydrolyzes SERCA-inhibitory Sarcolamban peptides in membranes of the sarcoplasmic reticulum, thereby ensuring proper regulation of SERCA. Cleavage is necessary and sufficient to maintain homeostasis and function of the micropeptides. Analyses on human Neprilysin, sarcolipin, and ventricular cardiomyocytes indicates that the regulatory mechanism is evolutionarily conserved. By identifying a neprilysin as essential regulator of SERCA activity and Ca homeostasis in cardiomyocytes, these data contribute to a more comprehensive understanding of the complex mechanisms that control muscle contraction and heart function in health and disease.

Voltage-sensitive calcium channels contribute to depolarization of both motor- and interneurons in animal studies, but less is known of their contribution to human motor control and whether blocking them has potential in future antispasmodic treatment in humans. Therefore, this study investigated the acute effect of Nimodipine on the transmission of human spinal reflex pathways involved in spasticity. In a double-blinded, cross-over study, we measured soleus muscle stretch- and H-reflexes, and tibialis anterior cutaneous reflexes in nineteen healthy subjects before and after Nimodipine (tab-let 60mg) or Baclofen (tablet 25mg).

Duchenne muscular dystrophy (DMD) is caused by mutations in the gene encoding dystrophin, a subsarcolemmal protein whose absence results in increased susceptibility of the muscle fiber membrane to contraction-induced injury. This results in increased calcium influx, oxidative stress, and mitochondrial dysfunction, leading to chronic inflammation, myofiber degeneration, and reduced muscle regenerative capacity. Fast glycolytic muscle fibers have been shown to be more vulnerable to mechanical stress than slow oxidative fibers in both DMD patients and DMD mouse models.

This literature review explores the role of biofeedback therapy (BFT) in managing functional fecal incontinence (FFI) in children - a common condition with a substantial impact on the quality of life. FFI diagnosis relies primarily on medical history and thorough physical examination and is categorized by the Rome IV criteria into functional constipation (FC) and functional nonretentive fecal incontinence (FNRFI). Treatment options for FFI remain limited, particularly for FNRFI.

As a gas molecule, hydrogen sulfide (HS) exerts neuroprotective effects. Despite its recognized importance, there remains a need for a deeper understanding of HS's impact on vascular smooth muscle cells and its role in ischemic brain injury. This study employs encompassing cultured primary cerebral vascular smooth muscle cells, oxygen-glucose deprivation/reoxygenation model, in vitro vascular tone assessments, in vivo middle cerebral artery occlusion and reperfusion experimentation in male rats, and the utilization of ROCK knockout, to unravel the intricate relationship between H2S and cerebrovascular diastolic function.

This study aimed to investigate the effects of an 8-week lat pull-down resistance training program with joint instability on pull-up performance in male college students. Thirty-four healthy recreationally active male college students were randomly assigned to either the joint instability resistance training (IRT) or traditional resistance training (TRT) group. Participants of the TRT and IRT groups performed lat pull-down training on stable and joint instability conditions for 8 weeks, respectively.
