Background/Objectives: Sarcopenia is characterized by loss of muscle mass and strength associated with aging. Recently, its links the gut-muscle axis have been reported, suggesting that probiotics could influence health. Methods: In present study, we investigated protective roles two lactic acid bacteria strains, Streptococcus salivarius subsp. thermophilus ST-G30 (ST-G30) Lacticaseibacillus paracasei LPc-G110 (LPc-G110), on skeletal atrophy induced dexamethasone (DEX) in C2C12 myotubes. Results: Our results demonstrated significantly alleviated DEX-induced myotube increasing myotubes' diameter (25.95 ± 1.28 vs. 15.30 0.30 μm, p < 0.01), improving fusion index (48.35 1.75 22.16 2.36%, 0.0001), protein content (1.78 0.02 1.56 0.01 mg/mL, 0.05) length (0.61 0.05 0.33 0.01, 0.05), whereas showed no significant effect these phenotypes (p > 0.05).

Abstract Abnormal microbial colonization in the gut at an early stage of life affects growth, development, and health, resulting short- long-term adverse effects. Microbial patterns preterm infants differ from those full-term that babies their mothers have more complicated prenatal postnatal medical conditions. Maternal complications, antibiotic exposure, delivery mode, feeding type, use probiotics may significantly shape microbiota life; however, these influences subside with age. Although some factors processes are difficult to intervene or avoid, understanding potential determinants will help developing timely strategies for a healthy infants. This review discusses underlying mechanisms.

Abstract The qualified presumption of safety (QPS) process was developed to provide a assessment approach for microorganisms intended use in food or feed chains. In the period covered by this Statement, no new information found that would change status previously recommended QPS taxonomic units (TUs). TUs list were updated based on verification, against their respective authoritative databases, correctness names and completeness synonyms. Of 54 notified EFSA between April September 2024 (33 as additives, 17 enzymes 4 novel foods), 50 not evaluated because: 12 filamentous fungi, 1 Enterococcus faecium 8 Escherichia coli (all excluded from evaluation), 29 already have status.
