13. Combined aliskiren and L-arginine treatment has antihypertensive effects and prevents vascular endothelial dysfunction in a model of renovascular hypertension
Angiotensin II is a key player in the pathogenesis of renovascular hypertension, a condition associated with endothelial dysfunction. We investigated aliskiren (ALSK) and L-arginine treatment both alone and in combination on blood pressure (BP), and vascular reactivity in aortic rings. Hypertension was induced in 40 male Wistar rats by clipping the left rena

14. Low dose of green tea catechins improves endothelial function and vascular smooth muscle cell reactivity in obese women
RESUMO OBJETIVO: A alta prevalência de obesidade no mundo traz vários problemas de saúde com a disfunção endotelial como um problema frequente. Investigamos se o consumo de baixa dose de extrato de chá verde (catequinas < 200 mg/dia) pode modificar a função endotelial, o perfil lipídico, a glicemia e a insulina de jejum, a glicose plasmática pós

15. 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

16. Effects of different frequencies of transcutaneous electrical nerve stimulation on venous vascular reactivity
Transcutaneous electrical nerve stimulation (TENS) is a type of therapy used primarily for analgesia, but also presents changes in the cardiovascular system responses; its effects are dependent upon application parameters. Alterations to the cardiovascular system suggest that TENS may modify venous vascular response. The objective of this study was to evalua

17. The putative role of ovary removal and progesterone when considering the effect of formaldehyde exposure on lung inflammation induced by ovalbumin
OBJECTIVE: Formaldehyde exposure during the menstrual cycle is known to affect the course of allergic lung inflammation. Because our previous data demonstrated that formaldehyde combined with an ovariectomy reduced allergic lung inflammation, we investigated the putative role of ovary removal and progesterone treatment when considering the effect of formald

18. Myosin light chain kinase is necessary for post-shock mesenteric lymph drainage enhancement of vascular reactivity and calcium sensitivity in hemorrhagic-shocked rats
Vascular hyporeactivity is an important factor in irreversible shock, and post-shock mesenteric lymph (PSML) blockade improves vascular reactivity after hemorrhagic shock. This study explored the possible involvement of myosin light chain kinase (MLCK) in PSML-mediated vascular hyporeactivity and calcium desensitization. Rats were divided into sham (n=12), s

19. Effects of the adipokine chemerin on the vascular reactivity: analysis in the rat aorta / Efeito da adipocina chemerin sobre a reatividade vascular: análise em aortas de rato
Embora seja na obesidade onde se observa hipertrofia e hiperplasia dos adipócitos e aumento da síntese e liberação de adipocinas, condição associada com resistência à insulina e disfunção endotelial, é de suma importância entender os efeitos biológicos de adipocinas, mais especificamente da adipocina chemerin, em condições não patológicas.

20. Eletroencefalograma na neuroemergência : impacto na avaliação de pacientes com alteração do estado de consciência e em pacientes na fase a hiperaguda do AVC = Electroencephalogram in neuroemergency : impact in the evaluation of patients with impairment of consciousness and patients in the hyperacute phase of stroke / Electroencephalogram in neuroemergency : impact in the evaluation of patients with impairment of consciousness and patients in the hyperacute phase of stroke
Title: Electroencephalogram in the Neuroemergency: Impact on evaluation of patients with impairment of consciousness and patients on hyperacute phase of stroke Introduction: The EEG is an inexpensive tool, but not available during out of business hours in most emergency departments. Our work was divided into two chapters: Impact of EEG in the diagnosis and m

22. Metformin, but not glimepiride, improves carotid artery diameter and blood flow in patients with type 2 diabetes mellitus
OBJECTIVE: To compare the effects of glimepiride and metformin on vascular reactivity, hemostatic factors and glucose and lipid profiles in patients with type 2 diabetes. METHODS: A prospective study was performed in 16 uncontrolled patients with diabetes previously treated with dietary intervention. The participants were randomized into metformin or glimepi

23. Increased immunohistochemical expression of YKL-40 in the spleen of patients with portal hypertension
YKL-40 has been identified as a growth factor in connective tissue cells and also a migration factor in vascular smooth muscle cells. To a large extent, the increase of serum YKL-40 is attributed to liver fibrosis and asthma. However, the relationship of the expression and clinical/prognostic significance of YKL-40 to the splenomegaly of patients with portal

24. Reduced occurrence of programmed cell death and gliosis in the retinas of juvenile rabbits after shortterm treatment with intravitreous bevacizumab
OBJECTIVE: Bevacizumab has been widely used as a vascular endothelial growth factor antagonist in the treatment of retinal vasoproliferative disorders in adults and, more recently, in infants with retinopathy of prematurity. Recently, it has been proposed that vascular endothelial growth factor acts as a protective factor for neurons and glial cells, particu
