1. Maternal Intake of Flaxseed During Lactation and Exercise Training Protect Against Salt Overload-Induced Aortic Remodeling in Adult Offspring
Abstract Background High dietary sodium intake can induce endothelial stiffness even without changes in blood pressure. Objectives To evaluate the effects of exercise training and chronic intake of sodium chloride solution on aortic morphology of male offspring of rat dams who consumed flaxseed during lactation. Methods Female rats were fed with a control

2. Acute Myocardial Infarction as the Initial Clinical Manifestation of Pernicious Anemia
Abstract Background High dietary sodium intake can induce endothelial stiffness even without changes in blood pressure. Objectives To evaluate the effects of exercise training and chronic intake of sodium chloride solution on aortic morphology of male offspring of rat dams who consumed flaxseed during lactation. Methods Female rats were fed with a control

3. Effect of Short-Term Inhalation of The Herbicide 2,4D on Cardiac Remodeling: Morphological Aspects
Abstract Background: Brazil is the worldwide leader in the long-term use of pesticides and herbicides. This compromises the health of handlers by causing harmful neurological, respiratory, and cardiovascular changes. The herbicide 2.4D has been shown to cause cardiac overload with subsequent pathological remodeling. Objective: To analyze the cardiac morpho

4. Monosodium glutamate neonatal treatment induces cardiovascular autonomic function changes in rodents
OBJECTIVES: The aim of this study was to evaluate cardiovascular autonomic function in a rodent obesity model induced by monosodium glutamate injections during the first seven days of life. METHOD: The animals were assigned to control (control, n = 10) and monosodium glutamate (monosodium glutamate, n = 13) groups. Thirty-three weeks after birth, arterial an

5. Sobrecarga de sal durante a gestação: efeito sobre o sistema renina angiotensiva sistêmico e renal da prole adulta de ratos Wistar / Salt overload during perinatal life: effect on the systemic and local renin-angiotensin system in adult offspring Wistar rats
O aporte de nutrientes ingerido pela mãe durante a gestação e o transporte dos nutrientes da placenta para o feto são essenciais para o crescimento fetal. A sobrecarga de sódio durante a gestação tem demonstrado ser um dos fatores responsáveis pela hipertensão na vida adulta da prole. Um estudo anterior em nosso laboratório demonstrou que além do

6. Immediate response of myocardium to pressure overload includes transient regulation of genes associated with mitochondrial bioenergetics and calcium availability
Ventricular hypertrophy is one of the major myocardial responses to pressure overload (PO). Most studies on early myocardial response focus on the days or even weeks after induction of hypertrophic stimuli. Since mechanotransduction pathways are immediately activated in hearts undergoing increased work load, it is reasonable to infer that the myocardial gene

7. Evaluation of the tissue and circulating renin-angiotensin system in offspring of dams that received salt overload or restriction during pregnancy and lactation / Avaliação do sistema renina - angiotensina tecidual e circulante em prole de ratas que receberam sobrecarga ou restrição de sal na dieta durante a gestação e amamentação
Epidemiologic studies reported that insults during the intrauterine life have been associated with many abnormalites such low birth weigth, type 2 diabetes, hypertension and obesity in adulthood[1]. Low birth weight and obesity in adulthood were observed in offspring of undernourished dams. In addition, a high expression of genes related with lipid metabolis

8. Sobrecarga e restrição de sal na dieta durante a gestação em ratas Wistar: efeitos sobre o sistema renina-angiotensina, função renal, resistência à insulina e pressão arterial / Dietary salt overload or restriction during gestation in Wistar rats: effects on the renin-angiotensin system, renal function, insulin resistance and blood pressure
Diversos estudos epidemiológicos têm relacionado doenças na vida adulta, como diabetes tipo-2 e hipertensão, e ambiente inadequado durante a vida fetal. Fatores distintos relacionados aos hábitos alimentares, como ingestão de sal na dieta, podem ter impacto importante no período perinatal. Recentemente, demonstramos que dieta hipossódica (HO) durante

9. A hipertensão arterial refrataria : caracterização fenotipica, avalliação cardiovascular morfo-funcional e correlação com polimorfismos geneticos de sistema renina-angiotensina e da sintase endotelial do oxido nitrico / Refractory hypertension : phenotypic characterization, cardiovascular morpho-functional assesssment and correlation with the renin-angiotensin-aldosterene and endothelial nitric oxide synthase gene polymorphisms
Refractory hypertension (HAR) is defined, according to the Seventh Joint National Committee (JNC VII), when the systolic arterial pressure remains above 140 mmHg and the diastolic arterial pressure above 90 mmHg even when taking three or more classes of anti-hypertensive agents including full-dose of a diuretic and the other agents at sub maximum doses with

10. Baroreflex function in conscious rats submitted to iron overload
Our hypothesis is that iron accumulated in tissue, rather than in serum, may compromise cardiovascular control. Male Fischer 344 rats weighing 180 to 220 g were divided into 2 groups. In the serum iron overload group (SIO, N = 12), 20 mg elemental iron was injected ip daily for 7 days. In the tissue iron overload group (TIO, N = 19), a smaller amount of elem

11. Efeitos de uma sobrecarga de sÃdio sobre a funÃÃo renal em ratos jovens submetidos à desnutriÃÃo intra-uterina
A desnutriÃÃo intra-uterina induz oligonefrenia, hipertensÃo e alteraÃÃes metabÃlicas que geram diabetes, obesidade e hipercolesteretemia. Neste trabalho, foi avaliado o efeito da desnutriÃÃo intra-uterina associada a uma sobrecarga de sÃdio sobre a proteinÃria, volume plasmÃtico, estresse oxidativo no rim, hemodinÃmica renal e morfologia glomeru

12. Chronic experimental myocardial infarction produces antinatriuresis by a renal nerve-dependent mechanism
The present study focused on the role of sympathetic renal nerve activity, in mediating congestive heart failure-induced sodium retention following experimental chronic myocardial infarction. Groups of male Wistar rats (240-260 g) were studied: sham-operated coronary ligation (CON3W, N = 11), coronary ligation and sham-operated renal denervation (INF3W, N =
