Nesiritide protects endothelial function after balloon-induced trauma in the iliac artery in rabbits

To assess the effect of nesiritide on the endothelial function of iliac arteries following endothelia trauma. Right iliac artery trauma was created with a balloon catheter. Ten rabbits were treated with a 4-week subcutaneous injection of nesiritide at a fixed daily dose of 0.1mg/kg. Ten rabbits received ...

Antioxidant effect of endothelin-1 receptor antagonist protects the rat kidney against chronic injury induced by hypertension and hyperglycemia

J. bras. nefrol; 41 (4), 2019
ABSTRACT Hypertension and Diabetes mellitus are the two main causes of chronic kidney disease that culminate in the final stage of kidney disease. Since these two risk factors are common and can overlap, new approaches to prevent or treat them are needed. Macitentan (MAC) is a new non-selective antagonis...

Endotelina-1, proteína C reactiva ultrasensible y actividad antioxidante en pacientes con hipotiroidismo subclínico y en eutiroideos con autoinmunidad tiroidea. Efectos del tratamiento con levotiroxina
Endothelin-1, high sensitivity C reactive protein and antioxidant activity in subclinical hypothyroid patients. Effects of levothyroxine treatment

RESUMEN La Endotelina-1 (ET1) y Proteína C Reactiva ultrasensible (PCRus) como marcadores de disfunción endotelial (DE) e inflamación vascular en hipotiroidismo subclínico (HS) han mostrado resultados controvertidos. El rol del estrés oxidativo y defensa antioxidante (TRAP) es motivo de discusión. ...

The effects of inhaled NO on plasma vasoactive factor and CTnI level in rabbits with acute massive pulmonary embolism

Acta cir. bras; 33 (7), 2018
Abstract Purpose: To investigate changes in the plasma concentrations of cardiac troponin I (CTnI), thromboxane A2 (TXA2), prostaglandin I2 (PGI2) and endothelin-1 (ET-1) in rabbits with massive pulmonary embolism (AMPE) and the impact of nitric oxide inhalation (NOI) on these indices. Methods: A tota...

Protective effects of melatonin on spinal cord injury

Int. j. morphol; 36 (2), 2018
Spinal cord injury causes neuron nerve fiber loss. The aim of this study was to investigate the neuroprotective, inflammatory and angiogenetic effects of melatonin on rat spinal cord injury (SCI). For spinal cord injury, a standard weight reduction method was used that caused moderate severity of injury ...

Evaluation of smoking as an additional risk factor for cardiovascular diseases among hemodialysis patients by increased levels of II-6, TNFα, hs-CRP and Endothelin-1

INTRODUCTION: Cardiovascular diseases (CVD) are one of the most common causes of mortality in chronic kidney disease. Smoking is a well defined risk factor for atherosclerotic cardiovascular disease. Interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), high sensitive C-reactive protein (hsCRP) and...

Expression of endothelin-1 and Ki-67 in normotensive and severe preeclamptic placentas

Int. j. morphol; 36 (1), 2018
SUMMARY: Severe preeclampsia (HELLP syndrome) is a life-threatening pregnancy complication, usually a severe form of preeclampsia. In this study, we aimed to examine histopathologic changes and Endothelin-1 and KI-67 expression levels by immunohistochemical methods in severe preeclamptic placentas. Sever...

Protective effect of dexmedetomidine against myocardial ischemia-reperfusion injury in rabbits

Acta cir. bras; 33 (1), 2018
Abstract Purpose: To investigate the influence of dexmedetomidine on myocardial ischemia-reperfusion injury (IRI) in rabbits. Methods: Twenty-four New Zealand white rabbits were randomly divided into two equal-sized groups: IRI group (group IR) and dexmedetomidine group (group D). Systolic blood pres...

Mecanismos regulatorios del tono vascular pulmonar neonatal: una perspectiva molecular

La adaptación al medio extrauterino incluye un aumento considerable de la PaO2, que induce especialmente cambios estructurales y vasoactivos en la circulación pulmonar, que llevarán a una circulación previamente pobremente irrigada, a recibir ∼100% del gasto cardíaco del recién nacido, permit...

Evaluation of biochemical and clinical markers of endothelial dysfunction and their correlation with urinary albumin excretion in patients with type 1 diabetes mellitus

ABSTRACT Objective Endothelial dysfunction (ED) plays an important role in the pathogenesis of diabetic nephropathy. The purpose of the study was to determine flow mediated endothelial dependent vasodilatation (FMD) measurements and serum soluble (s) endothelin-1 (ET-1), intercellular adhesion molecule...
