1. Indicações e resultados para o uso expandido da oclusão ressuscitativa por balão endovascular da aorta - REBOA.
RESUMO A oclusão ressuscitativa por balão endovascular da aorta (REBOA) é utilizada para controlar hemorragias não compressíveis do tronco como uma opção menos invasiva e com menos distúrbios fisiológicos quando comparado à toracotomia de emergência com clampeamento da aorta. Isso permite a melhora dos parâmetros hemodinâmicos até que a cirurgi

2. Late cardiac perconditioning by phenylephrine in an isolated rat heart model is mediated by mitochondrial potassium channels
The present study was designed to investigate the effect of early and late administration of phenylephrine during ischemia against regional ischemia-reperfusion injuries in an isolated rat heart model. All animals were randomly divided into experimental groups: (I) IR (Ischemic/ reperfusion): the hearts underwent 35 min of regional ischemia followed by 60 mi

3. O uso da tomografia computadorizada na triagem da lesão cardíaca penetrante.
RESUMO Objetivo: determinar se a tomografia computadorizada representa uma opção segura para triagem de lesões cardíacas penetrantes. Métodos: estudo transversal retrospectivo, que confrontou os achados tomográficos com os detectados na exploração cirúrgica em pacientes operados por suspeita de trauma cardíaco no período de janeiro de 2016 a jan

4. Association between Smoking and Alcohol Consumption and the Severity of Coronary Artery Injuries in Patients with AMI
Abstract Background: Smoking is the most important risk factor for coronary heart disease (CHD) and ischemic events; alcohol consumption, on the other hand, appears to have a protective role. Objective: Assess the association between smoking and alcohol consumption with the severity of coronary artery injuries in patients with acute myocardial infarction

5. Heart Injury with Projectile Lodged Inside the Heart
Abstract Penetrating heart injuries present high mortality rates. Increasing rates of urban violence have contributed to a significant rise in the number of heart injuries by firearm projectiles. Such injuries are associated with the highest mortality rates among penetrating cardiac injuries and may involve one or more cardiac chambers. We present the case o

6. Moderate physical training counterbalances harmful effects of low-protein diet on heart: metabolic, oxidative and morphological parameters
ABSTRACT Aims Maternal low-protein diet induces several impairments on cardiac system. Conversely, moderate exercise has been widely recommended to health improvement due to its effects on heart function. Thus, we investigated whether the moderate physical training is capable to offset the lasting injuries of a maternal protein restriction on the hearts of

7. Embolization by Bullet Dislodged from the Heart
Abstract Embolization by a dislodged projectile is a rare complication that may occur in cases of gunshot cardiac injuries. We report a case of a firearm projectile cardiac injury that evolved, with dislocation of the projectile during cardiac surgery, into embolization of the right external carotid artery.

8. Time-course effects of aerobic exercise training on cardiovascular and renal parameters in 2K1C renovascular hypertensive rats
Exercise training (Ex) has been recommended for its beneficial effects in hypertensive states. The present study evaluated the time-course effects of Ex without workload on mean arterial pressure (MAP), reflex bradycardia, cardiac and renal histology, and oxidative stress in two-kidney, one-clip (2K1C) hypertensive rats. Male Fischer rats (10 weeks old; 150�

9. Desenvolvimento, caracterizacao e aplicacao da matriz FTO/POLI(3-aminofenol) na deteccao de marcador de lesao cardiaca por fotoluminescencia de quantum dots
The heart is a vital organ propelling blood, that carries oxygen and nutrients throughout the body, but whenever these components do not reach it due to arterial obstruction, there is an electrical instability in the process of contraction of the muscle, causing arrhythmias that often, in less than an hour, causes acute myocardial infarction. The problem and

10. Obtenção de células de Salmonella resistentes a desidratação para o preparo de material de referência / Attainment of resistant cells of Salmonella the dehydration for the preparation of material of reference
Programs of control and management of the quality in laboratories, the necessity of standardization of the analysis methods and repeatability of the experimental data have stimulated the increase of the use of Reference Material (RM) in the microbiological analyses. Considering that the stages of preparation and storage of the MR are stress processes that ca

11. Evaluation of arterial stiffness by pulse wave velocity method in resistant and controlled hypertensives / Avaliação da rigidez arterial pelo metodo da velocidade de onda de pulso (VOP) em hipertensos resistentes e controlados
Introduction: In hypertensive patients, there is a relationship between morbidity and mortality and arterial damage, affecting one or several organs like: heart, brain, kidney and others. Therefore, large arterial injuries require early evaluation of cardiovascular risk factors, once they are major contributors to cardiovascular diseases. Among the simple an

12. Efeito de diferentes doses de silício, nitrogênio e potássio na incidência da traça-do-tomateiro,pinta-preta e produtividade do tomate industrial
Tomato production is at second place among vegetable crops in Brazil in economical relevance. This crop is exposed to many pests that limit yield. The aim of this research was to evaluate silicon, nitrogen and potassium effect on blight infection, tomato pinworm injuries and yield. The experiment was carried out at FAL- UnB in a completely randomized design,
