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. Pharmacological evaluation of the hydro-alcoholic extract of Campomanesia phaea fruits in rats
Resumo Campomanesia phaea (Myrtaceae), popularmente conhecida como cambuci, é uma das várias espécies de plantas que produzem frutos comestíveis amplamente utilizados na nutrição humana. Apesar de seu consumo e potencial econômico, há poucas pesquisas científicas sobre a Campomanesia, especialmente aquelas relacionadas aos seus benefícios terapêut

3. Effect of a rosmarinic acid supplemented hemodialysis fluid on inflammation of human vascular endothelial cells
Chronic systemic inflammation and repetitive damage of vascular endothelia by incompatible dialysis system are probable causes of cardiovascular disease in patients on dialysis. The present study aimed to assess in vitro biocompatibility and anti-inflammatory effect of hemodialysis fluid supplemented with rosmarinic acid (RA) using human umbilical vein endot

4. The Middle Ages Contributions to Cardiovascular Medicine
Abstract The historical period called the Middle Ages, a long interval between the 5th and the 15th centuries, is still commonly known as the Dark Ages, especially in the area of health sciences. In the last decades, this "classic" view of the Middle Ages has been gradually modified with advances in historiographical studies and the history of science. Durin

5. The role of oxytocin in cardiovascular regulation
Studies of body volume expansion have indicated that lesions of the anteroventral third ventricle and median eminence block the release of atrial natriuretic peptide (ANP) into the circulation. Detailed analysis of the lesions showed that activation of oxytocin (OT)-ergic neurons is responsible for ANP release, and it has become clear that activation of neur

6. Estudo da expressão e produção de componentes do sistema renina-angiotensina por fibroblastos de gengiva e ligamento periodontal humanos / Study of expression and production of the renin-angiotensin system components by gingival and periodontal ligament human fibroblasts
O Sistema Renina-angiotensina (SRA), e um sistema capaz de gerar hormonios peptideos com grande impacto na regulacao cardiovascular e na patogenese das doencas cardiovasculares. Este sistema opera, por meio das acoes da Angiotensina II, tanto em nivel sistemico (endocrino) quanto tecidual (local, paracrino/autocrino) controlando importantes funcoes, varias d

7. Alterações cardiovasculares de fêmeas de ratos espontaneamente hipertensos (SHR) relacionadas com a idade / Cardiovascular changes in female spontaneously hypertensive rats (SHR) age-related
Hypertension is a major cause of cardiovascular disorders, and the natural progression of this disease may trigger further changes in the circulatory system. Experimental models are widely used in studies on the changes that occur in the cardiovascular system induced by hypertension. The SHR is the model that most closely matches the human hypertension, as i

8. Análise de polimorfismos em tumores gliais humanos / Polymorphisms Analysis in Human Glial Tumors
The Central nervous system tumors represent about 2% of all cancers. Although the incidence of CNS tumors is small compared with other cancers, these tumors are among the most serious human malignancies, because they affect the body responsible for coordination and integration of all organic activities. Gliomas are the most common tumors of the CNS. Despite

9. Influência dos polimorfismos do receptor de leptina e o impacto da dieta e treinamento físico sobre as variáveis antropométricas, metabólicas e neurovasculares em mulheres obesas / Influence of leptin polymorphisms and the impact f diet and exercise training on the anthropometric, metabolic, neurovascular and hemodynamic variables in obese women
Leptin is an important component of a complex physiological system that contributes to the regulation of the organic energy balance. Leptin plasmatic concentration or mRNA quantities are positive related to gender, caloric intake, BMI and fat mass. Energy expenditure can be altered by leptin action through the nervous sympathetic stimulus. Leptin acts via it

10. Fenil éster do ácido caféico melhora a resposta ao estresse oxidativo em modelo animal de obesidade induzida por dieta hiperlipídica / Caffeic acid of phenethyl ester improves the oxidative stress response in animal model of obesity induced by high fat diet
Obesity is a disease that is increasing in a drastically way around the world and is implicated in many pathological conditions, such as insulin resistance, type 2 diabetes, dyslipidemia, fatty liver disease, hypertension and cardiovascular risk. Evidence has shown that obesity is a chronic oxidative stress state that is associated with metabolic and physiol

12. Development of a simulator of the human cardiovascular mechanics controlled by baroceptor reflex mechanism. / Desenvolvimento de um simulador da mecânica cardiovascular humana controlada pelo mecanismo reflexo baroceptor.
Nos últimos anos, o ensino de fisiologia tem sido fortemente beneficiado pelo desenvolvimento de modelos matemáticos e simuladores de paciente capazes de reproduzir com segurança partes específicas ou sistemas fisiológicos completos. Estudos mostram que aulas teóricas aliadas a simulações conseguem potencializar o nível de compreensão dos conceitos
