Conclusion: Metadoxine appears safe to use and seems efficient to improve liver functions following alcohol-related diseases. Further clinical trials will be necessary to determine if metadoxine can be promising for treating brain disorders. PROSPERO registration number: CRD42017072964.
PubMed 29485008 ↗Conclusion: We provided novel insights into semen indices in relation to URSA. Lower sperm number and quality might increase the risk of URSA, and oxidative stress and hormone metabolism in sperm as well as nucleic acid synthesis and oxidative stress in seminal plasma were related to URSA.
PubMed 32827532 ↗Conclusion: The robust association between miRNAs and metabolites, along with the substantial indirect impact of miRNAs via 5 hub metabolites on multiple clinical asthma metrics, suggests important integrated effects of miRNAs and metabolites on asthma. These findings imply that the indirect regulation of metabolism and cellular functions by miRNA influences Th2 inflammation, AHR, and airflow obstruction in childhood asthma.
