Hydrogen Sulfide Protects Hyperhomocysteinemia-Induced Renal Damage by Modulation of Caveolin and eNOS Interaction.

Sci Rep 2019 Feb 18;9(1):2223. Epub 2019 Feb 18.

Department of Physiology, School of Medicine, University of Louisville, Louisville, KY, 40292, USA.

The accumulation of homocysteine (Hcy) during chronic kidney failure (CKD) can exert toxic effects on the glomeruli and tubulo-interstitial region. Among the potential mechanisms, the formation of highly reactive metabolite, Hcy thiolactone, is known to modify proteins by N-homocysteinylation, leading to protein degradation, stress and impaired function. Previous studies documented impaired nitric oxide production and altered caveolin expression in hyperhomocysteinemia (HHcy), leading to endothelial dysfunction. Read More

Nitric Oxide 2019 Feb 14;86:12-20. Epub 2019 Feb 14.

Faculty of Pharmaceutical Sciences of Ribeirão Preto, University of São Paulo, Ribeirão Preto, SP, Brazil. Electronic address:

Purpose: This study investigated the intracellular mechanisms involved in the vasodilatation induced by the classic NO donor SNP and the non-classic NO donor cis-[Ru(bpy)2(py)(NO2)](PF6) (or RuBPY) in mesenteric resistance arteries obtained from renal hypertensive (2K-1C) and normotensive (2K) rats.

Methods: On the basis of fluorimetric assays in cultured vascular smooth muscle cells (VSMCs) isolated from 2K-1C and 2K rats, we measured NO release from SNP and RuBPY, cytosolic Ca concentration ([Ca]c), and reactive oxygen species (ROS) with the selective probes DAF-2DA, Fluo-3AM and the more selective probe for peroxynitrite (7-CBA), respectively. We determined isometric tension in mesenteric arteries to assess SNP- and RuBPY-induced relaxation. Read More

Renin dependent hypertension caused by accessory renal arteries.

Clin Hypertens 2018 1;24:15. Epub 2018 Nov 1.

Department of Medicine, Sarawak General Hospital, Ministry of Health Malaysia, Jalan Hospital, 93586 Kuching, Sarawak Malaysia.

Background: Hypokalemia in the presence of hypertension is often attributed to primary hyperaldosteronism as a cause of secondary hypertension, however secondary hyperaldosteronism may present similarly. Accessory renal arteries are variants in the vascular anatomy which are often thought to be innocuous but in some circumstances can cause renovascular hypertension leading to secondary hyperaldosteronism.

Case Presentation: We report 2 cases of hypertension with secondary hyperaldosteronism associated with accessory renal arteries. Read More

Vitamin D Deficiency Aggravates the Renal Features of Moderate Chronic Kidney Disease in 5/6 Nephrectomized Rats.

Front Med (Lausanne) 2018 10;5:282. Epub 2018 Oct 10.

Laboratorio de Investigacao Medica 12 (LIM12), Hospital das Clinicas HCFMUSP, Faculdade de Medicina, Universidade de São Paulo, São Paulo, Brazil.

The pathogenesis of chronic kidney disease (CKD) involves a very complex interaction between hemodynamic and inflammatory processes, leading to glomerular/vascular sclerosis, and fibrosis formation with subsequent evolution to end-stage of renal disease. Despite efforts to minimize the progression of CKD, its incidence and prevalence continue to increase. Besides cardiovascular diseases and infections, several studies demonstrate that vitamin D status could be considered as a non-traditional risk factor for the progression of CKD. Read More

Electroacupuncture Improves Baroreflex and -Aminobutyric Acid Type B Receptor-Mediated Responses in the Nucleus Tractus Solitarii of Hypertensive Rats.

Neural Plast 2018 30;2018:8919347. Epub 2018 Sep 30.

Key Laboratory of Shaanxi Province for Craniofacial Precision Medicine Research, Research Center of Stomatology, Xi'an Jiaotong University College of Stomatology, Xi'an, Shaanxi 710004, China.

Electroacupuncture (EA) has been reported to benefit hypertension, but the underlying mechanisms are still unclear. We hypothesized that EA attenuates hypertension, in part, through modulation of -aminobutyric acid (GABA) receptor function in the nucleus tractus solitarii (NTS). In the present study, the long-term effect of EA on GABA receptor function and expression was examined in the NTS of two-kidney, one-clip (2K1C) renovascular hypertensive rats. Read More

Florey Institute of Neuroscience and Mental Health, University of Melbourne, Parkville, Victoria, Australia.

Aims: Neuroinflammation is a common feature in renovascular, obesity-related, and angiotensin II mediated hypertension. There is evidence that increased release of the pro-inflammatory cytokine tumour necrosis factor-α (TNF-α) contributes to the development of the hypertension, but the underlying neural mechanisms are unclear. Here we investigated whether TNF-α stimulates neurons in the area postrema, a circumventricular organ, to elicit sympathetic excitation and increases in blood pressure. Read More

Loss of Renal Peritubular Capillaries in Hypertensive Patients Is Detectable by Urinary Endothelial Microparticle Levels.

Hypertension 2018 Nov;72(5):1180-1188

From the Division of Nephrology and Hypertension, Mayo Clinic, Rochester, MN (I.O.S., A.S., A.A., A.E., C.M.F., J.R.W., S.C.T., A.S.P., L.O.L.).

Hypertension, an important cause of chronic kidney disease, is characterized by peritubular capillary (PTC) loss. Circulating levels of endothelial microparticles (EMPs) reflect systemic endothelial injury. We hypothesized that systemic and urinary PTC-EMPs levels would reflect renal microvascular injury in hypertensive patients. Read More

Moderate-intensity exercise and renin angiotensin system blockade improve the renovascular hypertension (2K1C)-induced gastric dysmotility in rats.

Life Sci 2018 Oct 28;210:55-64. Epub 2018 Aug 28.

Postgraduate Program in Pharmacology, Federal University of Piauí, Teresina, PI, Brazil; Postgraduate Program in Food and Nutrition, Federal University of Piauí, Teresina, PI, Brazil; Department of Physical Education, Federal University of Piauí, Teresina, PI, Brazil. Electronic address:

Actually, arterial hypertension is a major public health concern, which involves the renin angiotensin aldosterone system (RAS), via activation of the angiotensin receptors AT and AT of the cardiovascular system. Although angiotensin is an important stimulant of the gut permeability to sodium and water, little is known about the effects of arterial hypertension on gut motor behavior. Thus, we evaluated in rats the effect of hypertension induced by two-kidney one-clip (2K1C) model on the gastric motility, as well as the influence of exercise and RAS blockers treatment in such phenomenon.

Beneficial effect of combined spironolactone and quinapril treatment on thrombosis and hemostasis in 2K1C hypertensive rats.

J Physiol Pharmacol 2018 Apr 4;69(2). Epub 2018 Jul 4.

Department of Biopharmacy, Medical University of Bialystok, Bialystok, Poland.

A strong correlation between raised aldosterone levels and increased risk of thrombotic disorders has been provided. Clinical studies have demonstrated the benefits of the addition of the aldosterone receptor antagonist to the standard therapy with angiotensin-converting enzyme inhibitor in the reduction of cardiovascular events in patients. We suggest that the benefits of this dual renin-angiotensin-aldosterone system (RAAS) blockade may be related to the drug's effects on the hemostatic and oxidative balance. Read More
