1. Characterization of laser Doppler signal fluctuations in microvascular flow / Caracterização das flutuações do sinal laser doppller do fluxo microvascular
The laser Doppler flow signal from the skin (LDFS) has low-frequency fluctuations which are related to microvascular mechanisms of flow control. The Fourier and the wavelet spectral analysis has been used to correlate fluctuations in the LDFS with the metabolic, metabolic NO-dependent, neurogenic and myogenic mechanisms of control in the frequency intervals

2. 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

3. Analysis of the vasomotor response and metabolic parameters in healthy elders to the use of statin / Análise da resposta vasomotora e parâmetros metabólicos em idosos "saudáveis"ao uso de estatina
The Brazil, where old people make up 7% of the population, will have the sixth greatest population of elderly people in the world. Cardiovascular disease increases significantly as a person grows older and evidences show the importance of the endothelium and hypercholesterolemia in arteriosclerosis. However, it has not been established yet if treating dyslip

4. Ionic mechanisms in spontaneous vasomotion of the rat basilar artery in vivo.
1. The goal of this study was to examine ionic mechanisms that modulate spontaneous rhythmic changes in vascular calibre or 'vasomotion' in the basilar artery in vivo. 2. Diameter of the basilar artery was measured through a craniotomy in anaesthetized rats under control conditions and during topical application of antagonists or alteration in the ionic comp

5. Decreased microvascular vasomotion and myogenic response in rat skeletal muscle in association with acute insulin resistance
In addition to increased glucose uptake, insulin action is associated with increased total and microvascular blood flow, and vasomotion in skeletal muscle. The aim of this study was to determine the effect of acute insulin resistance caused by the peripheral vasoconstrictor α-methylserotonin (αMT) on microvascular vasomotion in muscle. Heart rate (HR), mea

9. Effects of inhibition of nitric oxide formation on basal vasomotion and endothelium-dependent responses of the coronary arteries in awake dogs.
The role of nitric oxide in basal vasomotor tone and stimulated endothelium-dependent dilations in the coronary arteries in chronically instrumented awake dogs was studied by examining the consequences of inhibiting endogenous nitric oxide formation with the specific inhibitor of nitric oxide formation, NG-monomethyl-L-arginine (L-NMMA). In four awake dogs,

10. Influence of pressure alterations on tone and vasomotion of isolated mesenteric small arteries of the rat.
1. Myogenic responses may account for control of organ blood flow. The study of these responses without interference from the organ requires an isolation technique for vessels which contribute significantly to flow resistance. This study reports on experiments on isolated small mesenteric arteries. 2. Distal rat mesenteric arcade arteries and first-order bra

11. Atherosclerosis influences the vasomotor response of epicardial coronary arteries to exercise.
We studied the vasomotion of epicardial coronary arteries during exercise and tested the hypotheses that abnormal vasoconstriction is related to the presence of atherosclerosis and may be related to endothelial dilator dysfunction. During cardiac catheterization quantitative coronary angiography was performed in 21 patients during supine bicycle exercise. 21

12. Alteration of Vein Cyclic 3′:5′ Nucleotide Concentrations During Changes in Contractility*
The relative changes in vascular tissue levels of cyclic 3′:5′-guanosine monophosphate (cGMP) and cyclic 3′:5′-adenosine monophosphate (cAMP) were determined in bovine and canine vein strips that were quickfrozen during changes in contractility elicited by prostaglandins (PG) or isoproterenol. Prostaglandin F2α-induced venoconstriction was associate
