Cardiovascular complications are a primary focus in the clinical management of type 2 diabetes, as they are the leading causes of disability and mortality in individuals with diabetes. Insulin resistance and endothelial dysfunction commonly coexist in diabetic patients. An increasing body of research indicates a reciprocal and interconnected association between endothelial function and insulin resistance. Insulin resistance can manifest in two distinct forms: endothelial and metabolic, with the former predominantly affecting vascular endothelial cells and the latter primarily impacting peripheral cells. The understanding of endothelial insulin resistance is crucial in comprehending the pathophysiology of cardiovascular complications in type 2 diabetes. Hence, the objective of this study is to examine the correlations, interplays, and molecular pathways linking endothelial insulin resistance and metabolic insulin resistance, with the aim of offering novel insights and scholarly resources for the prevention and management of diabetic vascular complications.

Background And Aims: This study evaluated the predictive value of the APF risk score in East Asian patients undergoing open nephrectomy and its correlation with hypertension and NAFLD.
Methods And Results: A retrospective study used the clinical data of 82 patients who underwent ON between January 2010 and December 2022. Per their APF score, patients were categorized into groups A (0-2 points) and B (3-4 points).

Polycystic ovary syndrome (PCOS) is a prevalent endocrine and metabolic disorder, affecting approximately 11-13% of women of reproductive age. Women with PCOS experience a higher prevalence of infertility, pregnancy complications, and cardiometabolic disorders such as obesity, insulin resistance, and type 2 diabetes mellitus. Furthermore, psychiatric comorbidities, including depression and anxiety, significantly impact the quality of life in this population.

Background: Abnormalities in effort-based decision-making have been consistently reported in major depressive disorder (MDD). Evidence indicates that metabolic factors, such as insulin resistance and dyslipidemia, which are highly prevalent in MDD, are independently associated with reward disturbances. Herein, we investigate the moderating effect of metabolic factors on effort-based decision-making in individuals with MDD.

Intrauterine growth retardation (IUGR) has become a difficult problem in animal husbandry and is often accompanied by the occurrence of metabolic syndrome. tRNA-derived small RNAs (tsRNAs) are a novel class of regulatory small noncoding RNAs. However, the involvement of tsRNA in regulating the mechanism of IUGR remains unclear.

Lipid rafts are subdomains of the cell membrane that are rich in cholesterol and glycolipids, and they are involved in various cellular processes and pathophysiological mechanisms. However, the specific role of lipid rafts in hepatocyte dysfunction during the pathogenesis of metabolic dysfunction-associated steatotic liver disease (MASLD) is not fully understood. In this study, we investigated the impact of lipid rafts on insulin sensitivity and hepatocyte injury induced by saturated free fatty acids (sFFAs) using primary-cultured mouse hepatocytes.
