Simulated hemodynamics in human carotid bifurcation based on Doppler ultrasound...

Background: Atherosclerotic lesions commonly develop at arterial branch sites. Noninvasive carotid artery ultrasound is a well-established and effective method which allows real-time images and measurements of flow velocities. We aimed to develop a methodology for patient-specific computational 3D reconstruction and blood flow simulation based on ultrasound image data. Material and Methods: Subject-specific stu...

Can we improve outcomes in patients with previous coronary artery bypass surger...

INTRODUCTION AND OBJECTIVES: Prognosis and in-hospital management of patients with acute coronary syndrome (ACS) and a history of coronary artery bypass graft (CABG) surgery are still debated. The objective of this study was to characterize ACS patients with a CABG and to compare their in-hospital and postdischarge outcomes with those of patients without a CABG. METHODS: This ongoing prospective observational s...

Results of the routine use of 4F catheters for diagnostic catheterization in a ...

INTRODUCTION: Complications at the site of vascular access are the most common adverse events in cardiac catheterization. The use of small gauge catheters may reduce this risk and allow earlier ambulation, the main disadvantage according to some authors being inferior image quality. The aim of our study was to evaluate the safety and image quality of 4 French diagnostic catheters. METHODS: We performed a retro...

A Importância de um ECG Normal em Síndromes Coronarianas Agudas sem Supradesniv...

BACKGROUND: Admission ECG has a major impact on the diagnosis and management of non-ST elevation acute coronary syndromes (ACS). OBJECTIVE: To assess the impact of the admission ECG on prognosis over non-ST ACS. Population: prospective, continuous, observational study of 802 non-ST ACS patients from a single center. METHODS: Patients were divided in 2 groups: A (n=538) - Abnormal ECG and B (n=264) - Normal ECG....

Características agronômicas de cultivares de milho no estádio verde em duas épo...

Dois experimentos foram conduzidos em area de varzea no Campo Experimental do Caldeirao da Embrapa Amazonia Ocidental, Iranduba-AM, nos periodos de nov/97 a fev/98 e out/98 a dez/98, convencionados como epoca de semeadura I (inicio do periodo chuvoso) e epoca de semeadura II (final do periodo secao), respectivamente, com o objetivo de avaliar tres cultivares de milho doce (BR-400, BR-401 e BR-402) e duas de mil...

Cholesterol affects African swine fever virus infection

African swine fever virus (ASFV) enters cells by receptor mediated endocytosis and requires a fusion event between the viral envelope and the limiting membrane of the endosome at low pH. In order to investigate the role of cholesterol in the early stages of ASFV infection, we have studied the effect of the removal of cell and viral membrane cholesterol by cholesterol oxidase treatment of cells and virions, as w...
