25. On cytoadhesion of Plasmodium vivax: raison d'être?
It is generally accepted that Plasmodium vivax, the most widely distributed human malaria parasite, causes mild disease and that this species does not sequester in the deep capillaries of internal organs. Recent evidence, however, has demonstrated that there is severe disease, sometimes resulting in death, exclusively associated with P. vivax and that P. viv

26. Vascularization of the small intestine in lesser anteaters, Tamandua tetradactyla (Xenarthra: Myrmecophagidae)
The blood supply in the small intestine of seven Tamandua tetradactyla (Linnaeus, 1758), was studied. The method included preparation of the macroscopic collection report, perfusion of the arterial network with water (40ºC), injection of colored latex (Neoprene 650®, 2350-0003 Suvinil® dye), fixation in formaldehyde (10%), and preservation in ethanol (50%

27. Moderate exercise training promotes adaptations in coronary blood flow and adenosine production in normotensive rats
OBJECTIVES: Aerobic exercise training prevents cardiovascular risks. Regular exercise promotes functional and structural adaptations that are associated with several cardiovascular benefits. The aim of this study is to investigate the effects of swimming training on coronary blood flow, adenosine production and cardiac capillaries in normotensive rats. METHO

28. Effects of diabetes on myocardial capillary density and serum angiogenesis biomarkers in male rats
INTRODUCTION: Cardiovascular disease is one of the main causes of mortality and morbidity in diabetic patients. This study evaluated the effects of diabetes on myocardial capillary density and several serum angiogenic factors including nitric oxide, vascular endothelial growth factor, and soluble vascular endothelial growth factor receptors. METHODS: Twelve

29. Adaptação oxidativa e funcional progressiva do sistema cardiopulmonar secundária à hipertensão arterial pulmonar em ratos
Pulmonary Arterial Hypertension (PAH) is a disease that affects the pulmonary vessels, essentially pre-capillaries, leading to remodeling of the vascular wall. It is characterized hemodynamic syndrome, which is the increase in pulmonary vascular resistance and right ventricular afterload. A growing body of evidence shows the involvement of oxidative stress i

30. Efeitos do Roundup™ e do Thiodan em adultos de Astyanax bimaculatus (Characidae: Teleostei): Valores de CL50 e morfologia testicular / Effects of Roundup™ and the Thiodan in adults of Astyanax bimaculatus (Characidae: Teleostei): Values of CL50 and testicular morphology
The indiscriminated use of agrochemicals in modern agriculture is unleashing a series of damages to the environment posing serious threats to the survival of important ecosystems. The main objectives of the present study was to determine the LC50-96h and investigate the effects of Roundup™ (Monsanto) and Thiodan (Bayer) in testicular morphology of the

31. Análise fractal da vascularização da membrana corioalantóide de embriões de codornas japonesas (Coturnix japonica submetidas a campo eletromagnético de 60 Hz.
The formation of vascular network is governed mainly by two processes, vasculogenesis and angiogenesis. In vasculogenesis, the angioblastic which are the precursors of endothelial cells arising in germ layer (mesoderm) of the yolk sac (outside the embryo body). These angioblastic organize themselves to form blood islands, differing in blood vessels where the

32. An arbitrary lagrangian-eulerian method for surface-tension dominated flows with contact lines / Simulação numérica de escoamentos bidimensionais com superfícies livres e linhas de contato dinâmicas
An arbitrary lagrangian-eulerian finite element method to solve surface tension dominated flows is presented. Such flows are important in many applications, particularly in capillary channels, that appear in microscale flows. The resolution of such flows presents several challenges that are addressed in this work. The flow is solved only in the liquid phase,

33. Efeitos não-genômicos dos hormônios esteróides - aldosterona e corticosterona - sobre a acidificação do túbulo proximal (S2) de ratos: estudos de microperfusão tubular e capilar, in vivo . / Nongenomic effect of steroid hormones - aldosterone and corticosterone - on acidification of rat proximal tubule (S2) studies by tubular and capillary microperfusion, in vivo .
The purpose was to determine if aldosterone and corticosterone act on the acidification of proximal tubule and if these hormonal effects are genomic and/or nongenomic. Bicarbonate reabsorption was evaluated by microperfusion. Aldosterone and corticosterone caused a significant increase in JHCO3-. In the presence of ethanol, actinomycin D, cycloheximide or es

34. Estudo da microcirculação na hanseníase virchowiana com o uso da microscopia de luz ortogonal polarizada e com laser-doppler fluxometria / Microcirculation s research in leprosy with orthogonal polarization special imaging and laser doppler
Leprosy is an infectious disease with unique characteristics. One of them is the fact that it compromises not only the cutaneous and adnexial innervation, but also the innervation of the cutaneous microcirculation. Several articles indicate the impact of disautonomy on the microcirculatory level, citing the example of changes in vasomotor level. The present

35. Cardiorespiratory evaluation of juvenile rats experimentally envenomed with Tityus serrulatus venom
Accidental envenomation caused by Tityus serrulatus scorpions is very common in Brazil and may result in serious cardiorespiratory alterations that are frequently fatal to children. In the present study, the effects of T. serrulatus venom on the cardiorespiratory system of recently weaned male Wistar rats were evaluated. Fifteen animals were distributed into

36. Estratégias de pré-concentração em eletroforese capilar (CE): parte 1. Manipulação da velocidade eletroforética do analito
Capillary electrophoresis has become a well-established and routine-based separation technique. It is based on the differences between charged analyte mobility in aqueous or organic electrolytes. Its major limitation is the sensitivity due to small sample injection volumes and the narrow diameter of the capillaries, especially when UV detection is used. Ther
