Background: Recent studies have revealed a higher rate of cardiovascular complications in primary aldosteronism (PA) compared to patients with essential hypertension (EH). Asymmetric dimethylarginine (ADMA) is a marker of endothelial dysfunction that could contribute to increased cardiovascular risk in patients with PA.
Objectives: The aim of this study was to compare the levels of ADMA among patients with PA, controls with EH and healthy participants. Methods: Serum ADMA levels were determined, using commercially available competitive enzyme-linked immunosorbent assay.
Methods: Serum ADMA levels were determined, using commercially available competitive enzyme-linked immunosorbent assay.
Results: Patients with PA had significantly higher concentrations of ADMA than healthy controls (0.488 ± 0.085 vs. 0.433 ± 0.053 μmol/L, P = 0.027). No difference was found in ADMA levels between cases with PA and EH (0.488 ± 0.085 vs. 0.476 ± 0.075 μmol/L, р = 0.636). The difference between patients with EH and normotensive controls did not reach statistical significance (P = 0.06).
Conclusions: The lack of difference between ADMA levels in patients with PA and EH suggests that endothelial dysfunction is more likely related to hypertension per se than to the specific etiology of elevated blood pressure.

Background/objectives: Inadequate cardiovascular adaptation during pregnancy impairs endothelial function and vascular resistance, contributing to complications such as pre-eclampsia (PE) and gestational hypertension (GH). Neprilysin (NEP), a protease involved in vascular regulation, has been linked to PE, but its role in endothelial function and vascular adaptation remains unclear. This pilot study investigates the associations between soluble neprilysin (sNEP) and markers of vascular and renal function in high-risk pregnancies without PE.

Tacrolimus (TAC)-induced chronic nephrotoxicity (TAC nephrotoxicity) is a serious issue for long-term graft survival in kidney transplantation. However, the pathophysiology of TAC nephrotoxicity remains unclear. In this study, we analyzed whole blood samples from mice that developed TAC nephrotoxicity in order to discover its mechanism.

Background: Cardiac surgery-associated acute kidney injury (CSA-AKI) results in poor prognosis. Several risk factors for CSA-AKI have been reported, including preoperative creatinine level, cardiopulmonary bypass time, and perioperative blood pressure management. Only few studies have reported the effect of vascular stiffness on the incidence of CSA-AKI, and there are is no study reporting on endothelial function and its association with CSA-AKI.

Objectives: Nonsmall cell lung cancer (NSCLC) accounts for about 85% of all lung cancers. Asymmetric dimethylarginine (ADMA) is an emerging molecule that is highlighted in carcinogenesis and tumor progression in lung cancer. Since elevated concentrations of ADMA are observed in lung cancer patients, we aimed to explore its associations with inflammation markers and established prognostic indices.

Bromodomain-containing protein 4 (BRD4) plays a vital role in fibrosis of various organs. However, the underlying mechanism of BRD4 in renal fibrosis remains unclear. To construct in vitro and in vivo models of renal fibrosis, TCMK-1 cells were subjected to TGF-β1 treatment and mice were subjected to UUO surgery and adenine induction.
