Article Abstract
Introduction: Nicotinamide Mononucleotide (NMN) has gained attention as a precursor to Nicotinamide Adenine Dinucleotide (NAD+) in recent years, commonly utilized in anti-aging therapies. The anti-aging effects of NMN on muscle and liver functions in middleaged and elderly people are still unclear.
Objective: Based on available randomized controlled trials, we conducted a meta-analysis to evaluate the impact of NMN on muscle and liver functions in middle-aged and elderly individuals.
Methods: We conducted searches on three electronic databases (PubMed, Embase, Web of Science) for randomized controlled trials involving NMN interventions in middle-aged and elderly populations. Through the Cochrane Handbook, we assessed the specific methodological quality. All statistical analyses were obtained by Stata15, and statistical significance was set as P<0.05.
Results: There were 412 participants from 9 studies in this meta-analysis. Based on changes in gait speed (SMD: 0.34 m/s, 95%CI [0.03, 0.66] p = 0.033), NMN had significant effects on muscle mass. Moreover, NMN had a better effect on ALT (SMD: -0.29 IU/L, 95%CI [-0.55, -0.03] p = 0.028). Subgroup analysis indicated that administering a small dose of NMN exerted the most prominent impact on Homeostasis Model Assessment-Insulin Resistance (HOMA-IR).
Conclusion: NMN has positive efficacy in enhancing muscle function, reducing insulin resistance and lowering aminotransferase levels in middle-aged and elderly individuals. NMN is an encouraging and considerable drug for anti-aging treatment.

Most animals experience abrupt developmental transitions involving major tissue remodeling, but the links with metabolic changes remain poorly understood. We examined ontogenetic changes in mitochondrial volume, oxidative capacity, oxygen consumption capacity, and anaerobic capacity across four organs (gut, liver, heart, and hindlimb muscle) in Xenopus laevis from metamorphosis to adulthood. These organs differ in the extent of developmental transformation.

Purpose: To develop and validate a fast, motion-robust, free-breathing abdominal 3D T1ρ mapping method by combining variable-density diamond radial k-space sampling with fast-MAPSS (magnetization-prepared angle-modulated partitioned-k-space spoiled gradient-echo snapshots).
Methods: 3D MAPSS T1ρ imaging was performed at 3T using five spin-lock time (TSL) pairs in phantom scans and three TSL pairs in nine healthy volunteers. Phantom experiments compared Cartesian sampling (reference) with stack-of-stars and diamond radial sampling.

Introduction: Toxoplasma gondii is a zoonotic parasite of significant public health concern, particularly in regions where consumption of undercooked meat is common. Despite the importance of sheep as a potential source of human infection, understanding of T. gondii seroprevalence and tissue distribution in sheep in the Red Sea State in Sudan remains limited.

Background: Muscle quality index (MQI), a new metric for assessing sarcopenia, reflects the functional capacity of muscle. However, the associations between MQI and adverse health outcomes and the corresponding mechanisms are not well understood.
Objective: We aimed to prospectively evaluate the associations of MQI with risk of nine adverse health outcomes (ie, osteoarthritis, cardiovascular disease (CVD), type 2 diabetes mellitus (T2DM), respiratory disease, chronic kidney disease (CKD), liver disease, dementia, depression, and all-cause mortality), as well as the mediating role of metabolomics in these associations.

Background: Liver cirrhosis (LC) is a morbid condition associated with frequent hospitalization and high mortality. Effective self-management is essential for patients with LC to monitor fluctuating symptoms and follow complex treatment regimens. However, strategies are often unsustainable and insufficiently tailored to individuals with cognitive impairments.
