Unlabelled: Metabolic syndrome (MS) is a coexistence of metabolic risk factors affecting development of cardiovascular diseases. In the pathogenesis of MS there participate reactive oxygen species which are excessively produced in such elements of MS as hyperglycemia, insulin resistance and obesity. Vitamins A, C and E are an important part of the non-enzymatic antioxidative barrier in humans. The aim of the study was to estimate plasma vitamin A, C and E levels in patients with symptoms of MS.
Material And Methods: The study included 68 patients with symptoms of MS according to International Diabetes Federation criteria (2005), 37 men and 31 women, aged 34-65 years (mean age 57, 76 +/- 8, 29 years). The control group consisted of 24 healthy individuals without MS, 18 men and 6 women, aged 49-67 (mean age 58, 5 +/- 5, 6 years). Plasma vitamin A, C and E levels were estimated in patients and the control group with spectrophotometry using T60V spectrophotometer (PG Instruments).
Results: The plasma vitamin A, C and E levels were significantly lower (p < 0.05) in MS patients than in the healthy individuals without symptoms of MS. The most significant differences in the level of antioxidative vitamins in both groups were related to vitamin C and vitamin E.
Conclusions: The decreased level of vitamins A, C and E points to the weakening of antioxidative barrier in patients with MS.

Objective: Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterized by social communication differences and restricted interests. One proposed biologic mechanism underlying ASD is oxidative stress, leading to the clinical use of glutathione based on anecdotal reports of improved behavior in autistic children. In this pilot study, we tested this observation using a randomized clinical trial format to collect preliminary data on glutathione safety and efficacy.

Cardiovascular disease (CVD) remains the leading cause of morbidity and mortality globally, with oxidative stress playing a pivotal role in its progression. Free radicals produced via oxidative stress contribute to lipid peroxidation, leading to subsequent inflammatory responses, which then result in atherosclerosis. Antioxidants inhibit these harmful effects through their reducing ability, thereby preventing oxidative damage.

Background: Biological evidence has revealed antitumor effect of vitamin D, but whether it could predict the response to neoadjuvant chemotherapy (NAC) in breast cancer (BC) patients remains inconclusive. The aim was to investigate the association between pretreatment vitamin D level and response to NAC and subsequent survival outcomes in BC patients.
Materials And Methods: The authors systematically searched the Medline, Embase, Cochrane Library, and Web of Science databases and clinical trial registries to identify relevant articles from inception to 8 October 2024.

Introduction: Coenzyme Q10 (CoQ10) is a fat-soluble vitamin-like quinone. The plasma levels of CoQ10 are reduced in patients with chronic kidney disease (CKD). CoQ10 supplementation can improve mitochondrial function and decrease oxidative stress in these patients.

In order to elucidate the therapeutic effect and mechanism of action of Zhengqing Fengtongning Sustained-release Tablets on knee osteoarthritis, this study created a knee osteoarthritis model using 0.2 mL 40 g·L~(-1) papain and randomly divided the rats into the model group, high-dose and low-dose groups of Zhengqing Fengtongning Sustained-release Tablets, and celecoxib group. All groups were given the drug for four weeks, with the diameter of their knee joint being measured during this period.
