Exosomes, the smallest extracellular vesicle, contain various molecules and mediate cell-cell communication. A number of studies demonstrate exosomes are involved in important physiological and pathological processes. Moreover, microRNA (miRNA) regulating hypertension development through the suppression of certain translation was recently reported. However, roles of exosomes containing various molecules including miRNA on development of essential hypertension have not been examined. We tested the hypothesis that plasma exosomes regulate systemic blood pressure in normotensive and spontaneously hypertensive rats (SHR)...

Matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) are the predominant gelatinases in the developing lung. Studies have shown that the expression of MMP-2 and MMP-9 is upregulated in hypoxic fibroblasts, 15-hydroxyeicosatetraenoic acid (15-HETE) regulated fibroblasts migration via modulating MMP-2 or MMP-9, and that hypoxia/15-HETE is a predominant contributor to the development of pulmonary arterial hypertension (PAH) through increased angiogenesis. However, the roles of MMP-2 and MMP-9 in pulmonary arterial endothelial cells (PAECs) angiogenesis as well as the molecular mechanism of hypoxia-regulated MMP-2 and MMP-9 expression have not been identified...

PURPOSE OF REVIEW: Acute psychoemotional stress is one of the causes of a sharp increase in blood pressure. However, the question if the stress may promote the hypertensive disease development is still open. This review aims, firstly, to show that the genetically determined enhanced responsiveness to stress is linked to sustained hypertension development and, secondly, to characterize the main physiological mechanisms and genetic factors implicated in the pathogenesis of stress-sensitive hypertension...

Despite being a cardinal experimental model, the induction of cirrhosis in rats by repeated exposure to carbon tetrachloride (CCl4) has low reproducibility. Here, we compared two models of cirrhosis induced by orogastric administration of CCl4 once (CCl4-1xWk) or twice a week (CCl4-2xWk) for 12 weeks in male Sprague-Dawley rats. Control rats received water instead of CCl4. Both CCl4 protocols similarly attenuated body weight gain (p < 0.01 vs. Control). Although both CCl4 protocols increased hepatic fibrosis, portal hypertension and splenomegaly, the magnitude of these alterations was higher and more consistent in CCl4-2xWk rats...

Aims: Aircraft noise causes endothelial dysfunction, oxidative stress, and inflammation. Transportation noise increases the incidence of coronary artery disease, hypertension, and stroke. The underlying mechanisms are not well understood. Herein, we investigated effects of phagocyte-type NADPH oxidase (Nox2) knockout and different noise protocols (around-the-clock, sleep/awake phase noise) on vascular and cerebral complications in mice. Methods and results: C57BL/6j and Nox2-/- (gp91phox-/-) mice were exposed to aircraft noise (maximum sound level of 85 dB(A), average sound pressure level of 72 dB(A)) around-the-clock or during sleep/awake phases for 1, 2, and 4 days...

Kidney damage is a well-recognized complication of the antiphospholipid syndrome (APS), either primary or systemic lupus erythematosus (SLE)-associated APS. Kidney involvement in APS involves a variety of manifestations, such as renal artery thrombosis or stenosis, renal vein thrombosis, allograft loss due to thrombosis after kidney transplantation, and injury to the renal microvasculature, also known as APS nephropathy. Biopsy in patients with APS nephropathy includes acute thrombotic microangiopathy lesions and chronic intrarenal vascular lesions such as interlobular fibrous intimal hyperplasia, arterial and arteriolar recanalizing thrombosis, fibrous arterial occlusion, and focal cortical atrophy...

TRV027 is a biased agonist for the Angiotensin (Ang)-II type 1 receptor (AT1 R), able to recruit ß-arrestin 2 independently of G-proteins activation. ß-arrestin activation in the central nervous system (CNS) was suggested to oppose the effects of Ang-II. This study evaluates the effect of central infusion of TRV027 on arterial pressure (AP), autonomic function, baroreflex sensitivity and peripheral vascular reactivity. Spontaneously hypertensive (SH) and Wistar Kyoto (WKY) rats were treated with TRV027 for 14 days (20 ng/hour) delivered to the lateral ventricle via osmotic minipumps...

INTRODUCTION: Systemic arterial hypertension is prevalent in end-stage renal disease and is closely associated with left ventricular hypertrophy (LVH). Blood pressure (BP) behavior is unique in this population, and it is not clear which BP measurement should be used for treatment guidance. We aimed to evaluate the association of several methods of BP measurement with left ventricular mass index (LVMI) as hypertensive end-organ damage. MATERIALS AND METHODS: Patients on maintenance hemodialysis, 3 or 4 times per week for at least 3 months, were enrolled...

Aneurysms associated with arteriovenous fistulas (AVF) are rare but can cause significant morbidity. They are often diagnosed after rupture, pain, or embolization. We describe a unique case of a 35-year-old woman with a large iliac vein aneurysm related to an acquired AVF incidentally discovered on ultrasound during pregnancy. She had a diagnosis of "idiopathic" pulmonary hypertension for several years. This report details the diagnosis and treatment with an arterial stent graft that was effective in decreasing the size of the venous aneurysm and reversing the systemic changes associated with the disease...

Eman Y Gohar, David M Pollock
PURPOSE OF REVIEW: Men and women differ in the prevalence, pathophysiology and control rate of hypertension in an age-dependent manner. The renal endothelin system plays a central role in sex differences in blood pressure regulation by control of sodium excretion and vascular function. Improving our understanding of the sex differences in the endothelin system, especially in regard to blood pressure regulation and sodium homeostasis, will fill a significant gap in our knowledge and may identify sex-specific therapeutic targets for management of hypertension...

Atherosclerosis begins in youth and is associated with the presence of numerous modifiable cardiovascular (CV) risk factors, including hypertension. Pediatric hypertension has increased in prevalence since the 1980s but has plateaued in recent years. Elevated blood pressure levels are associated with impairments to cardiac and vascular structure and both systolic and diastolic function. Blood pressure-related increases in left ventricular mass (LVM) and abnormalities in cardiac function are associated with hard CV events in adulthood...
