The sarcoplasmic reticulum (SR) is a specialised organelle in skeletal muscle fibres that plays a pivotal role in regulating calcium dynamics crucial for muscle contraction and relaxation.

Sex differences in susceptibility to muscle damage are also of interest. This overview will briefly examine these questions and summarise the current evidence for oestrogenic influence on skeletal ...

Incubation conditions that permitted calcium oxalate uptake (steady-state filling or uptake rate) to be used as a marker for sarcoplasmic reticulum vesicles in homogenates and microsomal fractions ...

June 10, 2025 — Acetaminophen may be doing more than just dulling pain in your brain it could be stopping it before it even starts. Scientists at Hebrew University have discovered that a ...

Here, we review the latest progress in the structural and functional aspects of the myofiber, focusing on myofibril, the sarcoplasmic reticulum ... and transverse components across the myofiber to ...

Objective We performed a systematic review, meta-analysis and meta-regression to determine if dietary protein supplementation augments resistance exercise training (RET)-induced gains in muscle mass ...

In the final section, we consider specific steps in Ca signaling. Work on Ca cycling often takes insufficient notice of the flux balance condition. As discussed below, it is essential that postulated ...

There are 3 types of muscle in the body: Cardiac muscle is only found in the heart. Smooth muscle is found in the internal organs. Skeletal muscle hangs from our skeletons and allows us to move. In ...

Importantly, a single treatment of injured muscles with PGE2 dramatically accelerates muscle repair and recovery of strength. Skeletal muscles harbor quiescent muscle-specific stem cells (MuSCs) ...

The purpose of the present study was to compare the influence of aerobic exercise (AE) lasting 12 weeks to that of resistance exercise (RE) of the same duration on endoplasmic reticulum (ER ...
