25. Neuroprotective effect of atorvastatin in spinal cord ischemia-reperfusion injury
OBJECTIVES: Prevention of the development of paraplegia during the repair of the damage caused by descending thoracic and thoracoabdominal aneurysms remains an important issue. Therefore, we investigated the protective effect of atorvastatin on ischemia-induced spinal cord injury in a rabbit model. METHOD: Thirty-two rabbits were divided into the following

26. Vascular O-GlcNAcylation augments reactivity to constrictor stimuli by prolonging phosphorylated levels of the myosin light chain
O-GlcNAcylation is a modification that alters the function of numerous proteins. We hypothesized that augmented O-GlcNAcylation levels enhance myosin light chain kinase (MLCK) and reduce myosin light chain phosphatase (MLCP) activity, leading to increased vascular contractile responsiveness. The vascular responses were measured by isometric force displacemen

27. Determinação do impacto do oversizing da endoprótese sobre a aorta torácica. Estudo experimental em porcos / Impact of stent-graft oversizing on the thoracic aorta: experimental study in a porcine model
Introduction: The use of endovascular techniques to treat the various disorders of the aorta has supplanted traditional open techniques, and is particularly promising in trauma1. The traumatic rupture of the aorta is the second leading cause of death by traffic accident2, 3, and repair of these lesions with endoluminal stents has showed lower mortality and p

28. Sistematização da aorta abdominal, ramos colaterias parietais e viscerais e ramos terminais em coelhos da raça Nova Zelândia (Oryctolagus cuniculus)
In this study was defined the pattern, the variations and distribution of the parietal and visceral collateral branches and terminal branches of the abdominal aorta in New Zeland rabbits (Oryctolagus cuniculus), being used 30 animals, 14 males e 16 females, young adults. The arterial system was filled with red colored latex through the thoracic aorta in the

29. A esplenectomia aumenta as lesões ateroscleróticas em camundongos deficientes em apoproteína E submetidos a uma dieta aterogênica
Atherosclerosis is an inflammatory immune disease associated with lipid accumulation in the intima layer of arteries. The spleen plays an important immune function, but its influence in development of atherosclerosis remains unclear. Evaluation of the role of the spleen in atherosclerosis is justified due to the high frequency of total splenectomies and the

30. Vascular adaptive responses to physical exercise and to stress are affected differently by nandrolone administration
Androgenic anabolic steroid, physical exercise and stress induce cardiovascular adaptations including increased endothelial function. The present study investigated the effects of these conditions alone and in combination on the vascular responses of male Wistar rats. Exercise was started at 8 weeks of life (60-min swimming sessions 5 days per week for 8 wee

31. Ramos colaterais do arco aórtico e suas principais ramificações em nutria (Myocastor coypus) = Collaterals brances of the aortic arch and its main rami in nutria (Myocastor coypus) / Collaterals brances of the aortic arch and its main rami in nutria (Myocastor coypus)
Background: Nutria (Myocastor coypus), also known as Swamp Beaver, is a medium-sized semiaquatic rodent that belongs to the Capromyidae family. Originally from the southernmost part of South America, the species is distributed in several parts worldwide such as Europe and United States, where it has been used for commercial purposes due to the excellent qual

32. The effects of heated vegetable oils on blood pressure in rats
OBJECTIVES: The goal of this study was to determine the possible mechanism that is involved in the blood pressureraising effect of heated vegetable oils. METHODS: Adult male Sprague-Dawley rats were divided into 11 groups; the control group was fed with rat chow, and the other groups were fed with chow that was mixed with 15% weight/weight palm or soy oils,

34. Colaterais do arco aórtico da capivara (Hydrochoerus hydrochaeris) / Collaterals of the aortic arch in capybara (Hydrochoerus Hydrochaeris)
A capivara é um mamífero roedor, de origem sul-americana, herbívoro, semi-aquático, da família Hydrochoeridae. No presente trabalho foram utilizados sete espécimes de capivara (Hydrochoerus hydrochaeris), todas fêmeas. Após o preenchimento do sistema arterial com látex 603 corado em vermelho, procedeu-se à dissecção das peças com o objetivo de o

35. The effects of palm oil tocotrienol-rich fraction supplementation on biochemical parameters, oxidative stress and the vascular wall of streptozotocin-induced diabetic rats
OBJECTIVE: This study examined the effects of palm oil tocotrienol-rich fractions on streptozotocin-induced diabetic rats. METHODS: Animals were divided into three groups: (i) normal non-diabetic (NDM), (ii) diabetic treated (tocotrienol-rich fractions - TRF) and (iii) diabetic untreated (non-TRF). The treatment group received oral administration of tocotrie

36. RepercussÃo da desnutriÃÃo e do treinamento aerÃbio moderado sobre a estrutura da parede arterial de ratos em processo de envelhecimento
We evaluated the late effects of multideficient diet in early period of lactation and the possible effects and/or some alterations due to aging and moderate aerobic training (MAT) in luminal diameter and intima-media area of left common carotid arteries, horizontal aorta and thoracic horizontal aorta walls. Twenty-four male rats, Wistar, were separated accor
