Abstract

Background: Cardiac aging is closely associated with mitochondrial dysfunction and impaired quality control mechanism. Exercise has been shown to modulate mitochondrial homeostasis, however, its effects on cardiac mitophagy and mitochondrial dynamics during aging remain unclear. This study investigated the effects of moderate-intensity treadmill training on mitochondrial maintenance-related gene expression in the hearts of young and aged Wistar rats.Methods: Young and aged rats were divided into four groups: young control, young exercise, aged control, and aged exercise (n=6 per group). Exercise groups performed treadmill running at 20 m/min for 30 minutes/day, 5 days/week for 8 weeks. Cardiac gene expression levels of Pink1, Parkin, Mfn1, Mfn2, Opa1, Drp1, and Fis1 were analyzed using semi-quantitative polymerase chain reaction (PCR). Data were analyzed using one-way ANOVA or Kruskal–Wallis test followed by appropriate post hoc analyses.Results: Exercise significantly increased Mfn2 expression in aged exercise rats compared with aged controls (p=0.029), suggesting partial restoration of age-related decline. Expression of Mfn1 and Drp1 varied among groups but showed no significant pairwise differences. Expression levels of Opa1, Fis1, Pink1, and Parkin remained unchanged. These results indicate that moderate exercise selectively enhances mitochondrial fusion capacity while maintaining balanced fission and basal mitophagy activity.Conclusion: Moderate-intensity treadmill training promotes mitochondrial  fusion-related adaptation in aging cardiac tissue. Regular moderate exercise may represent a potential non-pharmacological strategy to support mitochondrial function and mitigate cardiovascular aging.

Abstract

Stiff person syndrome (SPS) is a rare immune-mediated neurological disorder characterized by progressive muscle stiffness and painful spasms that significantly impair functional ability. Although symptomatic and immunomodulatory therapies are commonly used, some patients remain refractory to standard treatments. Autologous hematopoietic stem cell transplantation (aHSCT) has been proposed as a potential therapeutic option for severe or treatment-resistant cases. This literature review aims to evaluate the clinical outcomes and safety of aHSCT in patients with SPS. A narrative literature review was conducted using published studies reporting the use of  aHSCT in SPS, including clinical trials, cohort, case series, and case reports. Relevant articles were identified through PubMed and Google Scholar, limited to studies published within the last ten years. A total of 134 articles were initially identified, followed by a selection process, and five eligible articles were included in this review. The reviewed studies demonstrated that aHSCT may lead to clinical improvement in selected patients with refractory SPS. Autologous HSCT reduced muscle stiffness and improved functional status. Treatment responses varied, and some non-responders were reported; however, overall clinical outcomes were favorable with acceptable safety profiles. In conclusion, aHSCT may be considered a potential therapeutic option for severe or treatment-resistant SPS, although further prospective studies are needed to confirm its efficacy and safety.

Abstract

Melasma is a hyperpigmentation disorder characterized by increased melanin production, commonly affecting women. Chronic UV exposure increases reactive oxygen species (ROS), and when ROS exceed the body's antioxidant capacity, oxidative stress occurs and is mitigated by glutathione peroxidase (GPx). However, evidence linking oral glutathione supplementation to endogenous GPx activity in patients with melasma remains limited. This study aims to evaluate the effect of glutathione supplementation on GPx levels and melasma severity in patients with melasma. A quasi-experimental, single-blind, pre-post study with a placebo control group was conducted at CITO Laboratory in South Jakarta among 54 women aged 30–59 years with melasma between December 2023 and May 2024. The participants were randomly allocated into two groups: a treatment group receiving oral reduced L-glutathione 500 mg once daily for one month, and a control group receiving a matched placebo tablet. GPx levels were measured in serum by ELISA, and modified melasma area and severity index (mMASI) scores were assessed before and after treatment; data were analyzed using the Wilcoxon signed-rank test for within-group comparisons and the Mann-Whitney U test for between-group comparisons at baseline. In the glutathione group, the median GPx level increased from 11.70 to 16.67 (p<0.001) and the median mMASI score decreased from 4.1 to 2.0 (p<0.001), whereas the placebo group showed no significant change in either GPx level (11.81 to 12.26, p=0.279) or mMASI score (0.6 to 0.6, p=0.250). In conclusion, these findings indicate that oral glutathione supplementation increases GPx levels and reduces melasma severity, suggesting that its clinical benefit may be mediated by strengthening the endogenous enzymatic antioxidant defense. Oral glutathione may therefore be considered a potential adjunct therapy for melasma; however, larger multicentre, double-blind trials with longer follow-up and additional oxidative stress biomarkers are needed to confirm these findings.
