Protein deficiency is known to cause ectopic fat accumulation in the liver. The aim of this study was to analyse the mechanism of suppression of hepatic fat accumulation by testosterone and to clarify the mechanism behind the gender difference in fatty liver formation due to protein deficiency. ⋯ Muscle protein synthesis downregulation owing to protein restriction and activation of autophagy following castration reduced muscle mass thereby releasing surplus energy and promoting steatosis in protein-restricted castrated rats despite increased energy expenditure in adipose tissue. We hypothesize that endogenous testosterone reduces hepatic lipid accumulation in protein-deficient male rats and provide novel findings on the gender-specific differences in hepatic steatosis.

The aim of this study was to evaluate the effect of the dietary supplementation of an alpha- and gamma-tocopherol mixture (1:5 ratio) in the adipose tissue expansion, hepatic steatosis, and expression of inflammatory markers induced by consumption of a high-fat diet (HFD) in mice. ⋯ The present study suggests that alpha- and gamma-tocopherol (1:5 ratio) supplementation attenuates the adipocyte enlargement, hepatic steatosis, and metabolic inflammation induced by HFD in association with PPAR-α/NF-κB modulation.

Management of inflammatory bowel disease (IBD) has always been a challenge for physicians. Current treatment protocols may cause numerous adverse effects. Selenium is known for its putative antiinflammatory properties. ⋯ This antiinflammatory property caused remission in animal models of colitis. 2) Selenium supports protective gut microbiota, which indirectly improves management of IBD. 3) Selenium may block some of the predominant tumorigenesis pathways proposed in colitis-associated colorectal cancer. 4) Selenium supplementation showed promising results in preliminary clinical studies, particularly in patients with selenium deficiency. While selenium supplementation seems to be beneficial for IBD, clinical studies have remained too preliminary in this regard. Randomized clinical trials are needed to measure the short-term and long-term effects of selenium on both active and quiescent IBD, particularly in patients with IBD who have documented selenium deficiency.

The aim of this study was to determine the interest in vitamin use during the COVID-19 pandemic usıng Google Trends data. ⋯ Vitamins attract public interest globally. Seasonal variation and COVID-19 shaped the popularity of vitamins both worldwide and in Turkey. The search frequency was highest in the autumn and spring, but the largest search related to all search terms was determined to be in March 2020. Interest in vitamins has increased since the beginning of the COVID-19 pandemic.
