: systemic hypertension (SH) involving endothelial dysfunction contributes to immune complex-mediated glomerulonephritis (ICGN). Objective, we demonstrate a relationship between ICGN and SH by analyzing vascular reactivity in renal aortic rings. : 48 male Wistar rats were divided into four groups: (a) control (C); (b) injected with bovine serum albumin (BSA); (c) receiving 200 mg/L NAME (an analog of arginine that inhibits NO production) in drinking water; and (d) receiving BSA and 200 mg/L NAME.

Introduction: Aldosterone participates in the pathogenesis of calcineurin inhibitor nephrotoxicity (CIN), producing renal vasoconstriction and transforming growth factor beta (TGFß) expression. The objective of this study was to assess aldosterone polymorphisms and relationships to plasma aldosterone levels and the development of renal histological lesions in kidney transplant patients.

Material And Methods: Patients with kidney graft biopsy were divided according to the presence or absence of CIN.

The density of Angiotensin II (Ang) receptors on tissue surfaces is regulated by multiple hormones, cytokines and metabolic factors and is profoundly affected by various pathological conditions, such as age, diet and environmental conditions. The participation of several cardiovascular risk factors in the regulation of Angiotensin II receptor expression has been incompletely studied. We performed an ex-vivo study with human aortic postsurgical specimens to test the hypothesis that Ang AT1 and AT2 receptor expression in human aortic arteries is associated with the presence of cardiovascular risk factors.

Background: The renal manifestations of IgA nephropathy are wide, including patients with asymptomatic disease. The probability of developing advanced renal disease after 20 years of diagnosis varies. The prevalence of mesangial deposits of IgA in otherwise healthy people has been studied previously and there are only 2 reports in which the diagnosis is made by time-zero renal biopsy (TO-RBx).

Article Synopsis
  • Nasal epithelium can help assess the effects of air pollution on human health, particularly in urban areas exposed to traffic emissions.
  • The study found a correlation between increased DNA damage in nasal cells and decreased levels of two key antioxidants, superoxide dismutase (SOD) and catalase (CAT), particularly during the autumn months.
  • The findings suggest the importance of both exogenous antioxidant supplements and a healthy diet in enhancing cellular defenses against oxidative stress resulting from air pollution exposure.
