Aim: Adipokines are associated with several oxidative stress-related diseases and pathologic conditions. We aimed to assess the association between antioxidants and adipokines in obese adults.
Methods And Materials: In this cross-sectional study, a total of 160 obese women were included. Body composition and anthropometric characteristics were measured. Dietary intakes were assessed by 3-day, 24-h dietary recall. Blood samples were obtained following an overnight fasting. Serum concentrations of adipokines including progranulin, retinol binding protein 4 (RBP4) and Angiopoietin-related growth factor 6 (ANGPTL6) was measured using an enzyme-linked immunosorbent assay. ANCOVA and the linear regression model analysis was performed to assess the relationship between Progranulin, RBP4, AnGPTL6, and antioxidants.
Results: Mean age of included women was 39.31 ± 12.10. Mean and standard deviation for BMI was 35.05 ± 4.26 in this obese population. There was a positive significant association between ANGPTL6 and vitamin D intake (p < 0.001). Also, there was a marginal association between RBP4 and vitamin A (p = 0.063) intake, but after adjustment age, and fat mass, we found a significant association (p = 0.008). However, the associations between dietary antioxidants, progranulin, and ANGPTL6 were not statistically significant.
Conclusions: ANGPTL6 and RBP4 levels directly associated with dietary vitamins D and A intake, respectively. But, according to the results, the association between ANGPTL6 and vitamin D was bidirectional. The suggested associations probably can be useful in the development of interventional studies for management of chronic diseases.

Maximal physical effort induces a disturbance in the body's energy homeostasis and causes oxidative stress. The aim of the study was to determine whether prooxidant-antioxidant balance disturbances and the secretion of adipokines regulating metabolism, induced by maximal intensity exercise, are dependent on body composition in young, healthy, non-obese individuals. We determined changes in the concentration of advanced protein oxidation products (AOPP), markers of oxidative damage to nucleic acids (DNA/RNA/ox), and lipid peroxidation (LPO); catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx) activity, as well as concentrations of visfatin, leptin, resistin, adiponectin, asprosin, and irisin in the blood before and after maximal intensity exercise in men with above-average muscle mass (NFAT-HLBM), above-average fat mass (HFAT-NLBM), and with average body composition (NFAT-NLBM).

Dietary sulfur amino acid restriction (SAAR) elicits various health benefits, some mediated by fibroblast growth factor 21 (FGF21). However, research on SAAR's effects on the heart is limited and presents mixed findings. This study aimed to evaluate SAAR-induced molecular alterations associated with cardiac remodeling and their dependence on FGF21.

Alterations of plasma lipoprotein levels and oxidative stress are frequently observed in obese patients, including low high-density lipoprotein (HDL) cholesterol (HDL-C) levels and alterations of HDL composition. Dysfunctional HDL with lower antioxidant and anti-inflammatory properties have also been demonstrated in obesity. There is increasing evidence that white adipose tissue (WAT) participates in several metabolic activities and modulates HDL-C levels and function.

Erectile dysfunction (ED) is a pathophysiological condition in which the patients cannot achieve an erection during sexual activity, and it is often overlooked yet prevalent among diabetic men, globally affecting approximately 35-75% of diabetic individuals. The precise mechanisms through which diabetes contributes to ED remain elusive, but the existing literature suggests the potential involvement of nerve and vascular damage that affects the penile supply. In the present review, we reanalyze the existing human single-cell transcriptomic data from patients having diabetes mellitus-associated ED with normal erections.

Obesity is characterized by an imbalance between energy intake and expenditure that triggers abnormal growth of adipose tissues. Dimethyl fumarate (DMF) and its primary active metabolite, monomethyl fumarate (MMF), are Nrf2 activators and have been recognized as strategic antioxidants. This study aimed to evaluate the potential of MMF and DMF to interfere with adipogenesis and obesity, and identify the molecular mechanisms involved.
