Association Between Sarcopenia and Acupressure Testing in Older Adults Requiring Long-Term Care.

: This study analyzed the relationship between pressure pain test outcomes and sarcopenia in elderly patients and explored possible clinical applications. : The participants included 143 older adults requiring long-term care who could be diagnosed with sarcopenia. Along with sarcopenia diagnosis, the participants underwent acupressure testing symmetrically at nine sites (occiput, lower cervical, trapezius, supraspinatus, second rib, lateral epicondyle, gluteus, greater trochanter, and knee), totaling 18 sites.

Decreased number of satellite cells-derived myonuclei in both fast- and slow-twitch muscles in HeyL-KO mice during voluntary running exercise.

Background: Skeletal muscles possess unique abilities known as adaptation or plasticity. When exposed to external stimuli, such as mechanical loading, both myofiber size and myonuclear number increase. Muscle stem cells, also known as muscle satellite cells (MuSCs), play vital roles in these changes.

EF-hand calcium sensor, EfhP, controls transcriptional regulation of iron uptake by calcium in .

The human pathogen () poses a major risk for a range of severe infections, particularly lung infections in patients suffering from cystic fibrosis (CF). As previously reported, the virulent behavior of this pathogen is enhanced by elevated levels of Ca that are commonly present in CF nasal and lung fluids. In addition, a Ca-binding EF-hand protein, EfhP (PA4107), was partially characterized and shown to be critical for the Ca-regulated virulence in .
