Aim: To evaluate the relationship of apelin and nitric oxide (NO) to endothelial dysfunction in type 1 diabetics.
Patients And Methods: Sixty two type 1 diabetics and 30 healthy age and sex matched controls were included. Blood samples for apelin, NO, glycosylated hemoglobin (HbA1c), and lipid profile were collected. Albumin/creatinine ratio was assessed in urine. Flow mediated dilatation (FMD) via ultrasound was done.
Results: The mean age of diabetics were 16.3 ± 1.5 yrs (14.0 - 19.0 yrs), and duration of disease, were 9.4 ± 2.9 yrs (5.0 - 16.5 yrs). FMD and FMD/nitrate mediated dilatation (NMD) ratio were lower in diabetics. NO was decreased, while apelin and albumin/creatinine ratio were increased significantly in diabetics. There was a positive correlation between apelin and HbA1c. On the contrary, NO had a negative correlation with HbA1c, albumin/creatinine ratio, LDL-c and OxLDL.
Conclusion: Diabetic patients had endothelial dysfunction and high apelin level, with no related to each other. High level of apelin is associated with bad glycemic control. Obesity had no role to increase in apelin level. NO is related to diabetic nephropathy and atherosclerosis. We recommend a further large study to evaluate the relationship of apelin with endothelial dysfunction.

The aberrant vascular response associated with tendon injury results in circulating immune cell infiltration and a chronic inflammatory feedback loop leading to poor healing outcomes. Studying this dysregulated tendon repair response in human pathophysiology has been historically challenging due to the reliance on animal models. To address this, our group developed the human tendon-on-a-chip (hToC) to model cellular interactions in the injured tendon microenvironment; however, this model lacked the key element of physiological flow in the vascular compartment.

Background: Cardiovascular risk factors (CRFs) like hypertension, high cholesterol, and diabetes mellitus are increasingly linked to cognitive decline and dementia, especially in cerebral small vessel disease (cSVD). White matter hyperintensities (WMH) are closely associated with cognitive impairment, but the mechanisms behind their development remain unclear. Blood-brain barrier (BBB) dysfunction may be a key factor, particularly in cSVD.

In the current age of technological advancement, stress has emerged as a silent pandemic affecting individuals, especially young generations, globally. Factors such as increased competition, social pressures fueled by social media and smartphones, and a sense of diminished control in the face of modern challenges contribute to rising stress levels. In addition to the negative implications on mental well-being, stress affects physiological processes such as the menstrual cycle.

Background: Androgenic anabolic steroids (AASs) are synthetic drugs structurally related to testosterone, with the ability to bind to androgen receptors. Their uncontrolled use by professional and recreational sportspeople is a widespread problem. AAS abuse is correlated with severe damage to the cardiovascular system, including changes in homeostasis and coagulation disorders.

Background: Myocardial ischemia-reperfusion (I/R) injury and coronary microcirculation dysfunction (CMD) are observed in patients with myocardial infarction after vascular recanalization. The antianginal drug trimetazidine has been demonstrated to exert a protective effect in myocardial ischemia-reperfusion injury.
Objectives: This study aimed to investigate the role of trimetazidine in endothelial cell dysfunction caused by myocardial I/R injury and thus improve coronary microcirculation.
