1. Cardiovascular involvement in COVID-19: not to be missed
Abstract In December 2019, a striking appearance of new cases of viral pneumonia in Wuhan led to the detection of a novel coronavirus (SARS-CoV2). By analyzing patients with severe manifestations, it became apparent that 20 to 35% of patients who died had preexisting cardiovascular disease. This finding warrants the important need to discuss the influence of

2. Continuous blood purification treatment for endotoxin-induced acute respiratory distress syndrome
This study aimed to explore the effects of continuous blood purification (CBP) treatment in pigs affected with acute respiratory distress syndrome (ARDS). A total of 12 healthy male pigs, weighing 12±1.8 kg, were randomly and equally assigned to the control and experimental groups. The ARDS pig model was prepared by intravenous injections of endotoxin (20 �

3. Gender-dependent effects of aging on the kidney
It is well known that the kidney plays an important role in the development of cardiovascular diseases such as hypertension. The normal aging process leads to changes in kidney morphology, hemodynamics and function, which increase the incidence of cardiovascular events in the elderly population. These disturbances are influenced by several factors, including

4. Influencia das variações posturais sobre as forças hemodinamicas e a sua correlação com a espessura intima-media das arterias carotidas e popliteas / Postural changes, hemodynamics forces and correlation with intima-media thickness of carotid and popliteal arteries
Atherosclerosis of peripheral arteries typically affects vessels of the lower limbs, suggesting that local hemodynamic stimuli play a role in this process. The present study evaluated the effects of body posture changes on carotid and popliteal circumferential wall tension (CWT) and investigated the relationship between local CWT and intima-media thickness (

5. Human saphenous vein organ culture under controlled hemodynamic conditions
INTRODUCTION: Saphenous vein grafting is still widely used to revascularize ischemic myocardium. The effectiveness of this procedure is limited by neointima formation and accelerated atherosclerosis, which frequently leads to graft occlusion. A better understanding of this process is important to clarify the mechanisms of vein graft disease and to aid in the

6. Exposição à radiação ionizante dos profissionais de saúde em hemodinâmica: o enfoque da enfermagem / Exposure of health professionals to ionizing radiation at hemodynamic: the nursing s vision
Ionizing radiations have been used in the contemporary medicine, inserted in disgnostic and therapeutical contexts. Therefore, the object of this study was the relation among ionizing radiation exposition and the work process of the health professionals at hemodynamic; the objectives were: know the profile of the professionals working at hemodynamic unit, id

7. Avaliação da utilização de sistema de suspensão abdominal mecânica: estudo experimental em cães / Evaluation of abdominal wall lifting system utilization: experimental study in dogs
Com o intuito de avaliar sistema de suspensão mecânica da parede abdominal, elaborou-se protocolo experimental, estudando-se trinta cães, distribuídos em três grupos experimentais de maneira aleatória: grupo pneumoperitônio com gás carbônico, grupo suspensão pela cavidade peritoneal e grupo suspensão abdominal (intraperitoneal) pela tela subcutân

8. Leukocyte trafficking in alveoli and airway passages
Many pulmonary diseases preferentially affect the large airways or the alveoli. Although the mechanisms are often particular to each disease process, site-specific differences in leukocyte trafficking and the regulation of inflammation also occur. Differences in the process of margination, sequestration, adhesion, and migration occur that can be attributed t

9. Hemodialysis-Induced Cardiac Injury: Determinants and Associated Outcomes
Background and objectives: Hemodialysis (HD)-induced myocardial stunning driven by ischemia is a recognized complication of HD, which can be ameliorated by HD techniques that improve hemodynamics. In nondialysis patients, repeated ischemia leads to chronic reduction in left ventricular (LV) function. HD may initiate and drive the same process. In this study,

10. Macula densa cell signaling involves ATP release through a maxi anion channel
Macula densa cells are unique renal biosensor cells that detect changes in luminal NaCl concentration ([NaCl]L) and transmit signals to the mesangial cell/afferent arteriolar complex. They are the critical link between renal salt and water excretion and glomerular hemodynamics, thus playing a key role in regulation of body fluid volume. Since identification

11. A mathematical model of the cytosolic-free calcium response in endothelial cells to fluid shear stress
Important among the responses of endothelial cells to flow stimuli are cytosolic-free calcium transients. These transients are mediated by several factors, including blood-borne agonists, extracellular calcium, and fluid-imposed shear forces. A mathematical model has been developed describing the recognition and transduction of shear stress to the secon
