Long-term chronic intermittent exposure to altitude hypoxia is a labor phenomenon requiring further research. Using a rat model, we examined whether this type of exposure differed from chronic exposure in terms of pulmonary ...

Objective The aim of the present study is to evaluate the artery of Adamkiewicz by multidetector computed tomography angiography (MCTA) in a Brazilian population. Methods Two independent observers evaluated 86 coronary ...

Hypertension is a silent enemy taking into a consideration that at the beginning of the disease no signs or symptoms are shown that can alert to the person that they have this disease, being a pathology of great care, ...

Work at high altitude in shifts exposes humans to a new form of chronic intermittent hypoxia, with still unknown health consequences. We have established a rat model resembling this situation, which develops a milder form ...

The case of a six-day-old neonate admitted in an emergency situation because of dyspnea and increasing cyanosis is reported. Despite abnormal opacification on the chest X-ray and left ventricular overload on the electrocardiogram ...

Coronary artery aneurysms, commonly atherosclerotic, are usually asymptomatic and can be diagnosed incidentally during investigation for ischemic heart disease or on autopsy. An asymptomatic giant right coronary artery ...

BACKGROUND: Vascular cells express different phenotypes in adult and fetal vessels, and the extracellular matrix they synthesize should reflect these differences. Alterations of vascular proteoglycan/glycosaminoglycan is ...
