Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as nonalcoholic fatty (NAFLD), encompasses a range of conditions from steatosis to steatohepatitis (NASH). Its prevalence, especially among patients with metabolic syndrome, highlights its growing global impact. The pathogenesis MASLD involves dysregulation, inflammation, oxidative stress, genetic factors and, notably, mitochondrial dysfunction. Recent studies underscore the critical role dysfunction in MASLD's progression. Therapeutically, enhancing function has gained interest, along lifestyle changes and pharmacological interventions targeting processes. FDA's approval resmetirom for metabolic-associated (MASH) fibrosis marks significant step. While represents progress, further research is essential understand MASLD-related fully. Innovative strategies like gene editing small-molecule modulators, alongside interventions, can potentially improve treatment. Drug repurposing new targets will advance therapy, addressing increasing burden. Therefore, this review aims provide better understanding identify more effective preventive treatment strategies.

Abstract Myocardial ischaemia–reperfusion (IR) injury poses a severe threat to cardiac health, particularly in the ageing population, where susceptibility such damage is significantly heightened owing age‐related declines mitochondrial function, thus highlighting mitochondria as crucial targets for innovative therapies. The aim of this study was investigate combined modality therapy involving transplantation and boosters mitoquinone melatonin address myocardial IR aged rats. A total 54 male Wistar rats, 22–24 months, were randomly divided into groups that either received or not, subjected various treatments, both individually combination. induced by temporarily blocking reopening left anterior descending coronary artery. Mitoquinone given intraperitoneally 14 days prior ischaemia, while isolated administered intramyocardially, respectively, at onset reperfusion. Finally, we evaluated changes haemodynamic indices, creatine kinase‐MB levels, function endpoints expression biogenesis genes, including sirtuin 1 ( SIRT‐1 ), peroxisome proliferator‐activated receptor gamma coactivator 1‐alpha PGC‐1α ) nuclear respiratory factor 2 NRF‐2 ). triple enhanced decreased levels improved along with genes This approach elicited significant cardioprotection comparison single dual provided substantial rat hearts improving through / profiles, suggesting promising strategy mitigating elderly patients.

α-Lipoic acid (ALA) is a naturally occurring compound with diverse biological functions, widely distributed in animal and plant tissues. It has attracted considerable attention due to its versatile therapeutic potential. However, despite these promising prospects, the clinical application of ALA remains limited by low bioavailability chemical instability an incomplete understanding multifaceted mechanisms across various diseases. This review provides comprehensive overview biochemical properties ALA, including direct free-radical-scavenging activity, regeneration endogenous antioxidants, chelation metal ions, modulation inflammatory responses. We also highlight current evidence regarding ALA’s roles efficacy major diseases, such as neurodegenerative disorders, lung cardiovascular diabetes. Furthermore, recent advancements innovative strategies ALA-based derivatives drug-delivery systems are summarized, emphasizing their potential address complex diseases necessity for further translational studies. aims provide theoretical foundation rational design therapies, thereby supporting future applications optimization strategies.

Heart aging involves a complex interplay of genetic and environmental influences, leading to gradual deterioration cardiovascular integrity function. Age-related physiological changes, including ventricular hypertrophy, diastolic dysfunction, myocardial fibrosis, increased arterial stiffness, endothelial are influenced by key mechanisms like autophagy, inflammation, oxidative stress. This review aims explore the therapeutic potential plant-derived bioactive antioxidants in mitigating heart aging. These compounds, often rich polyphenols, flavonoids, other phytochemicals, exhibit notable antioxidant, anti-inflammatory, cardioprotective properties. substances have intricate properties, ability scavenge ROS, enhance endogenous antioxidant defenses, regulate signaling pathways, impede fibrosis inflammation-promoting processes. By focusing on molecular linked cardiac aging, produced from plants provide significant promise reduce age-related decline improve general health. Through comprehensive analysis preclinical clinical studies, this work highlights associated with promising effects antioxidants. The findings may helpful for researchers identifying specific molecules preventive heart.

This study aimed to investigate the protective effects of vitamin B complex and alpha-lipoic acid (ALA) pre-treatments on hepatic ischemia–reperfusion injury (IRI) in rats, focusing their potential enhance antioxidant defense mechanisms reduce post-ischemic liver damage. Thirty male Wistar albino rats were divided into four groups: sham group (n = 10), IRI + ALA 10). In IRI, B, groups, underwent 45 min ischemia followed by 60 reperfusion. Serum levels aspartate aminotransferase (AST), alanine (ALT), urea, creatinine, lactate dehydrogenase (LDH) measured. Additionally, serum total status (TAS) oxidant (TOS) assessed, oxidative stress index (OSI) was calculated. Liver tissue samples collected for morphological evaluation. ALT, AST, creatinine LDH better compared with but difference statistically significant only (p < 0.05). The lowest TOS OSI reported groups these had significantly higher TAS Our findings suggest that a alone or combination reduces enhancing anti-oxidative status. low dose may be co-factor results studies larger doses are required determine its liver.
