Summary: The study used a laboratory tumbling simulator to investigate the effectiveness of the tumbling process in reducing the toughness of raw beef cuts, and found that longer tumbling times significantly reduced the toughness of muscle fibers and connective tissue.

Summary: Age-related loss of skeletal muscle mass in mice is mainly due to fiber shortening rather than fiber loss, with alterations in muscle morphology playing a significant role in muscle wasting. Tendon length and pennation angle remain consistent across the lifespan, while changes in connective tissue selectively impact muscle structure.

Summary: Bioactive peptides are physiologically active peptides derived from proteins through digestion, fermentation, or enzymatic hydrolysis. They have been shown to positively impact health-related parameters and may also play a significant role in sports nutrition, improving body composition, muscular performance, and reducing muscle damage. Further research is needed to explore the potential mechanisms and limitations of using bioactive peptides in sports nutrition.

Summary: This research studied the antifibrotic and myogenic responses of injured muscles to stretching exercise, and confirmed the feasibility of using ultrasonic Nakagami parametric index (NPI) to assess muscle morphology. Stretching can decrease muscle fibrosis and promote myogenesis.

Summary: This study investigated the effect of adding natural sorbents to pig feed on the fatty acid content of pig meat and fat. The results showed that the sorbents had limited effects on muscle tissue but had significant effects on kidney fat. The impact of different sorbents varied, but overall, they did not have a negative effect on the nutritional and pro-health quality of pig adipose tissue during fattening.

Summary: The study found that eccentric elbow flexor exercise can lead to an increase in biceps brachii ECT thickness, which correlates positively with palpation pain, affecting delayed onset muscle soreness.

Summary: The study found that during the transition from E35 to E80, 11.43% of the genome switched compartment status, 14.53% of topologically associating domains experienced changes in intradomain interactions, and 2,730 genes showed differential promoter-enhancer interactions and (or) enhancer activity. The alterations in genome architecture were associated with the expression of genes involved in neuromuscular junction, embryonic morphogenesis, skeletal muscle development, or metabolism. Key genes like NEFL, MuSK, SLN, Mef2D, and GCK were identified as playing significant roles in these processes. Notably, Sox6 and MATN2 were highlighted for their important roles in the transition from primary to secondary myofibres formation. The study provided insight into genomic reorganization and constructed high-resolution interaction maps for studying gene expression control during this developmental period.

Summary: The Wooden Breast (WB) and Spaghetti Meat (SM) abnormalities in chicken meat industry present challenges with differences in collagen fiber structure, resulting in distinct textural properties. Histological and FTIR analysis revealed that WB has a mixture of thick and thin collagen fibers with more beta-sheets, while SM has fewer and shorter collagen fibers with the lowest mature collagen content. These insights into molecular changes can help to clarify the underlying causes of the abnormalities.

Summary: Recent research has shown a strong interaction between muscle fibers and intramuscular connective tissue, as well as between muscles and fasciae, challenging the idea that muscles are the sole organizers of movement. The innervation and vascularization of muscles are also connected with intramuscular connective tissue. Luigi Stecco introduced the term "myofascial unit" to describe the anatomical and functional relationship between fascia, muscle, and accessory elements. This narrative review aims to explore the scientific evidence supporting the concept of the myofascial unit as the fundamental element for peripheral motor control.

Summary: Developmental genes are often controlled by multiple enhancers with similar specificities, making it difficult to fully understand their function when these regulatory elements are deleted. The authors show that deleting one enhancer in the Pitx1 testbed locus leads to regulatory and cellular changes, resulting in altered cell identities and gene expression levels.

Summary: Prenatal caffeine exposure was found to inhibit long bone development in female fetal rats by reducing osteogenesis-related gene expression and H-type blood vessel abundance. This effect was mediated through decreased CTGF expression by miR375.

Summary: This study aimed to investigate the effects of daily consumption of 10 g/d and 20 g/d collagen peptide (CP) on pain, function, and physical and mental health in middle-aged active adults. The results showed that 10 g/d CP improved activities of daily living (ADLs) and pain over 6 months, while 20 g/d CP improved physical and mental health, but only in females.
