BACKGROUND: Skin alterations are among the most prominent signs of aging, and they arise from both intrinsic and extrinsic factors that interact and mutually influence one another. The use of D-galactose as an aging model in animals has been widely employed in anti-aging research. Adipose tissue-derived mesenchymal stem cells (Ad-MSCs) are particularly promising for skin anti-aging therapy due to their capacity for effective re-epithelization and secretion of various growth factors essential for skin regeneration. Accordingly, we aimed to examine the potential utility of Ad-MSCs as a therapy for skin anti-aging. METHODS: In this study, we isolated and characterized adipose-derived mesenchymal stem cells (Ad-MSCs) from the epididymal fat of male Sprague Dawley rats. We assessed the in vitro differentiation of Ad-MSCs into epidermal progenitor cells (EPCs) using ascorbic acid and hydrocoritsone. Additionally, we induced skin aging in female Sprague Dawley rats via daily intradermal injection of D-galactose over a period of 8 weeks. Then we evaluated the therapeutic potential of intradermal transplantation of Ad-MSCs and conditioned media (CM) derived from differentiated EPCs in the D-galactose-induced aging rats. Morphological assessments, antioxidant assays, and histopathological examinations were performed to investigate the effects of the treatments. RESULTS: Our findings revealed the significant capability of Ad-MSCs to differentiate into EPCs. Notably, compared to the group that received CM treatment, the Ad-MSCs-treated group exhibited a marked improvement in morphological appearance, antioxidant levels and histological features. CONCLUSIONS These results underscore the effectiveness of Ad-MSCs in restoring skin aging as a potential therapy for skin aging.

The hepatoprotective activity of the ethanol extract of Astragalus kahiricus (Fabaceae) roots against ethanol-induced liver apoptosis was evaluated and it showed very promising hepatoprotective actions through different mechanisms. The extract counteracted the ethanol-induced liver enzymes leakage and glutathione depletion. In addition, it demonstrated anti-apoptotic effects against caspase-3 activation and DNA fragmentation that were confirmed by liver histopathological examination. Moreover, the phytochemical study of this extract led to the isolation of four cycloartane-type triterpenes identified as astrasieversianin II (1), astramembrannin II (2), astrasieversianin XIV (3), and cycloastragenol (4). The structures of these isolates were established by HRESI-MS and 1D and 2D NMR experiments. The antimicrobial, antimalarial, and cytotoxic activities of the isolates were further evaluated, but none of them showed any activity.

Background: Work life of individuals with diabetes differs from that of those without diabetes. Work may interfere with diabetes self-management tasks, resulting in intentional hyperglycemia at work (IHW) and poor glycemic control. Diabetes also can affect work productivity due to work-related diabetes distress (WRDD) and impaired work ability (WA). Methodology: A cross-sectional study was done at the Specialized Medical Hospital Mansoura University, which included 323 working patients with diabetes. They were subjected to personal interviews to collect socio-demographic data, occupational, diabetes and other pertinent medical histories. Questionnaires for measuring IHW, WRDD and WA were completed. Clinical and A1c data were obtained from their records. Results: The prevalence of always high IHW, poor/very poor glycemic control, high WRDD and poor/moderate work ability was: 23.8%, 60.1%, 34.7% and 74.6%, respectively. The predictors of always high IHW were: 1) Below university education; 2) Treatment with insulin only or combined with oral drugs and 3) High WRDD. The predictors of poor/very poor glycemic control were urban residence, always and almost high IHW. The predictors of high WRDD were mentally-requiring jobs or both mentally- and physically-requiring jobs, duration of diabetes greater than 14 years and treatment with insulin. The predictors of poor/moderate WA were 'high' WRDD, 'almost high' and 'high a few times' IHW ratings. Conclusions Most of the studied population suffered mainly from poor/very poor glycemic control and poor/moderate work ability, while a lower proportion had high WRDD. This highlighted the need for workplace modifications and interventions to help workers with diabetes control their diabetes, improve their work ability and reduce WRDD to increase productivity.

Objective: To explore the efficacy of earthworm's coelomic fluid against gentamicin-induced hepatic and renal toxicity in rats. Methods: The animals were divided randomly into three groups (n = 6 per group): control, gentamicin, and Allolobophora caliginosa coelomic fluid-treated groups. Toxicity was established after injection of gentamicin daily for 8 days at a dose of 100 mg/kg. Aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, total proteins, albumin, creatinine, urea, uric acid, malondialdehyde, glutathione, catalase and histopathology of tissues were investigated in the study. Results: Allolobophora caliginosa coelomic fluid significantly decreased urea, creatinine, uric acid, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and malondialdehyde levels while significantly increasing levels of total proteins, albumin, glutathione and catalase. The histopathological investigation showed partial restoration of renal and hepatic architecture. Conclusions: This study shows the potency of Allolobophora caliginosa coelomic fluid in improving the biochemical and histopathological changes induced by gentamicin in the liver and kidney of the rats.
