AB  - Background: Multiple sclerosis (MS) is a chronic demyelinating disorder intricately linked to perturbations in
trace element levels. While previous studies have explored circulating trace elements in a limited sample, understanding the impact of demographic and clinical variables on the elemental profile within a larger cohort
remains elusive.
Methods: This study aimed to evaluate essential trace elements (Cr, Mn, Co, Cu, Zn, and Se) in the sera of 215 MS
patients compared to a meticulously matched control group of 100 individuals with similar gender and age. Our
main objective was to identify potential variations in elemental profiles based on demographic and clinical
parameters among MS patients, elucidating the prospective relevance of supplementing specific essential trace
elements.
Results: Data indicated a significant decrease in serum levels of Mn, Co, Zn, and Se, and an increase in Cr in MS
patients compared to controls. These trace elements not only discriminated between MS patients and controls but
also exhibited distinctive capabilities among demographic subgroups. Gender, smoking habits, and age strata
(20–40 years and 41–60 years) revealed discernible variations in elemental profiles between MS patients and
their control counterparts. Se demonstrated the singular ability to stratify cases of extreme MS severity, mild
relapsing-remitting MS (RRMS) and highly severe secondary progressive MS (SPMS). In contrast, Co significantly
differentiated RRMS from primary progressive MS (PPMS), while Cu significantly differentiated SPMS from
PPMS. Additionally, Cu showed a negative correlation with MSSS, while Mn and Zn showed a positive correlation
with EDSS.
Conclusion: These findings underscore a substantive deficiency in Mn, Co, Zn, and Se in the MS cohort, supporting
targeted supplementation with these trace elements. This study provides a comprehensive understanding of the
intricate relationship between essential trace elements and MS, paving the way for further research into
personalized nutritional interventions for this complex neurological disorder.

AB  - The adipose tissue renin–angiotensin system (RAS) is proposed to be a pathophysiological link between adipose tissue dysregulation and metabolic disorders induced by a fructose-rich diet (FRD). RAS can act intracellularly. We hypothesized that adipocyte nuclear membranes possess angiotensin receptor types 1 and 2 (AT1R and AT2R), which couple to nuclear signaling pathways and regulate oxidative gene expression under FRD conditions. We analyzed the effect of consumption of 10% fructose solution for 9 weeks on biochemical parameters, adipocyte morphology, and expression of AT1R, AT2R, AT1R-associated protein (ATRAP), NADPH oxidase 4 (NOX4), matrix metalloproteinase-9 (MMP-9), and manganese superoxide dismutase (MnSOD) in adipose tissue of Wistar rats. We detected AT1R and AT2R in the nuclear fraction. FRD reduced the level of angiotensin receptors in the nucleus, while increased AT1R and decreased AT2R levels were observed in the plasma membrane. FRD increased the ATRAP mRNA level and decreased MnSOD mRNA and protein levels. No significant differences were observed for MMP-9 and NOX4 mRNA levels. These findings coincided with hyperleptinemia, elevated blood pressure and triglycerides, and unchanged visceral adipose tissue mass and morphology in FRD rats. Besides providing evidence for nuclear localization of angiotensin receptors in visceral adipose tissue, this study demonstrates the different effects of FRD on AT1R expression in different cellular compartments. Elevated blood pressure and decreased antioxidant capacity in visceral fat of fructose-fed rats were accompanied by an increased AT1R level in the plasma membrane, while upregulation of ATRAP and a decrease of nuclear membrane AT1R suggest an increased capacity for attenuation of excessive AT1R signaling and visceral adiposity.
