Involvement of lipid microdomains in human endothelial cells infected by Streptococcus agalactiae type III belonging to the hypervirulent ST-17

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND Streptococcus agalactiae capsular type III strains are a leading cause of invasive neonatal infections. Many pathogens have developed mechanisms to escape from host defense response using the host membrane microdomain machinery. Lipid rafts play an important role in a variety of cellular funct...

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 ...

Efeitos da morte cerebral na microvasculatura pulmonar em um modelo experimental de doador de pulmão

J. bras. pneumol; 46 (2), 2020
RESUMO Objetivo A morte cerebral (MC) desencadeia alterações hemodinâmicas e inflamatórias importantes, comprometendo a viabilidade dos órgãos empregados em transplantes. Para compreender melhor as alterações microcirculatórias nos pulmões de doadores com MC, o presente estudo investigou a mic...

Síndrome vasomotor: puente de unión entre la disfunción endotelial y la esclerosis arterial

Rev. colomb. cardiol; 26 (3), 2019
Resumen Introducción: Los síntomas vasomotores y la disfunción endotelial probablemente resulten del déficit estrogénico postmenopausia; no obstante, la relación de ambos con la progresión de la aterosclerosis es un tema controversial. Objetivo: Identificar en mujeres de edad mediana con disfu...

Adiponectina, doença cardiovascular e suas relações com o exercício físico: revisão narrativa

Há uma estreita relação entre os níveis circulantes de adiponectina, resistência à insulina e risco cardiovascular. As evidências disponíveis que avaliaram a relação entre adiponectina e exercício físico apresentam algumas controvérsias. Estudos recentes mostraram que o treinamento aerób...

Central role of obesity in endothelial cell dysfunction and cardiovascular risk

SUMMARY Atherosclerosis is the leading cause of mortality in the contemporary world. The critical role of the endothelial cells (EC) in vascular homeostasis, the metabolic changes that take place when the cell is activated, and the elements involved in these processes have been widely explored over the p...

Influência das Quimiocinas na migração dos linfócitos T e na permeabilidade de células endoteliais na infecção pelo vírus Dengue

Dengue é uma doença causada pelo vírus dengue (DENV) com amplo espectro clínico, variando desde uma infecção assintomática a casos graves, com manifestações hemorrágicas e/ou extravasamento plasmático, que podem levar o paciente ao óbito. Durante a infecção, mediadores pró-inflamatórios, ...

Pharmacological characterization of the calcium influx pathways involved in nitric oxide production by endothelial cells

Einstein (Säo Paulo); 17 (3), 2019
ABSTRACT Objective: To characterize the calcium influx pathways implicated in the sustained elevation of endothelial intracellular calcium concentration, required for the synthesis and release of relaxing factors. Methods: We evaluated the effect of the newly synthesized pyrazole derivatives, described...

Protein malnutrition effects of perivascular bone marrow microenvironment on the regulation of hematopoiesis

Protein malnutrition (PM) causes anemia and leukopenia by reduction of hematopoietic precursors and impaired production of mediators that induce hematopoiesis, as well as structural and ultrastructural changes in the bone marrow (BM) extracellular matrix. Hematopoiesis occurs in the bone marrow (BM) in d...

The effect of hirudin on antagonisting thrombin induced apoptosis of human microvascular endothelial cells

Acta cir. bras; 34 (1), 2019
Abstract Purpose: To investigate whether hirudin exerts its antithrombin action to decrease the ratio of Human Microvascular Endothelial Cells (HMVECs) apoptosis. Methods: Human microvascular endothelial cells (HMVECs) cultured in the third and fifth generations were used. HMVECs were divided into nor...
