1. Penile microvascular endothelial function in hypertensive patients: effects of acute type 5 phosphodiesterase inhibition
The primary aim of this study was to evaluate penile endothelial microvascular function in patients with primary arterial hypertension and age-matched normotensive subjects using laser speckle contrast imaging (LSCI). Additionally, we analyzed the acute penile microvascular effects induced by oral phosphodiesterase type 5 inhibitor (sildenafil; SIL) administ

2. Gender differences in microcirculation: Observation using the hamster cheek pouch
OBJECTIVES: Estrogen has been shown to play an important protective role in non-reproductive systems, such as the cardiovascular system. Our aim was to observe gender differences in vivo with regard to the increase in macromolecular permeability and leukocyte-endothelium interaction induced by ischemia/reperfusion as well as in microvascular reactivity to v

3. Repeatability of the evaluation of systemic microvascular endothelial function using laser doppler perfusion monitoring: clinical and statistical implications
OBJECTIVE: An awareness of the repeatability of biological measures is required to properly design and calculate sample sizes for longitudinal interventional studies. We investigated the day-to-day repeatability of measures of systemic microvascular reactivity using laser Doppler perfusion monitoring. METHODS: We performed laser Doppler perfusion monitoring

4. Vimentin and laminin are altered on cheek pouch microvessels of streptozotocin-induced diabetic hamsters
OBJECTIVE: Normal endothelial cells respond to shear stress by elongating and aligning in the direction of fluid flow. Hyperglycemia impairs this response and contributes to microvascular complications, which result in deleterious effects to the endothelium. This work aimed to evaluate cheek pouch microvessel morphological characteristics, reactivity, permea

5. Relationships among cephalic hase of digestion, food intake and microvascular reactivity in healthy subjects / Relações entre fase cefálica da digestão, consumo alimentar e reatividade microvascular de indivíduos saudáveis
A fase cefálica de secreção de insulina (FCSI) ocorre dentro da fase cefálica da digestão, em aproximadamente dez minutos entre a estimulação oro-sensorial pelo alimento e o início da absorção deste e determina um incremento rápido dos níveis basais de insulina. A FCSI parece ser importante para a tolerância normal à glicose. A hipótese deste

6. 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

7. Avaliação da reatividade microvascular e da rigidez arterial em pacientes com diabetes tipo 1 / Microvascular reactivity and atrial stiffness assessment in tipe 1 diabetes
A disfunção endotelial tem sido sugerida como evento precoce na patogênese das complicações vasculares do DM1. O presente estudo objetivou avaliar a função endotelial na microcirculação e rigidez arterial no diabetes tipo 1 comparando com controles não diabéticos e correlacionando com variáveis clínicas, demográficas e laboratoriais. Foram aval

8. A microcirculação da bolsa da bochecha do hamster sob a influência do diabetes mellitus experimental induzido por estreptozotocina: aspectos morfofuncionais / Microcirculation of hamster cheek pouch under the influence of exerimental diabetes mellitus induced by streptozocin morpho-functional aspects
Diabetes Mellitus is a chronic metabolic disease with multiple etiologic factors (genetic, viral and immunological) that results in absolute or relative insulin deficiency, causing persistent elevated blood glucose levels. Nowadays, Diabetes Mellitus is considered as an important health concern due to its increasing prevalence and high morbimortality. Its cl

9. Estudo dos mecanismos de ação da hidroquinona e fenol sobre o recrutamento leucocitário em respostas inflamatórias / Study of mechanisms of action of hydroquinone and phenol on leukocyte recruitment in inflammatory response
Hydroquinone (HQ) is one of the metabolites of benzene responsible for the toxic effects of exposure to solvent, as well as being part of the diet, medicines, tobacco and polluting the environment. Considering the immunotoxicity of this substance, our laboratory has investigated the role of exposure to HQ by prolonged period of time on acute inflammatory res

11. Bench-to-bedside review: Microvascular dysfunction in sepsis –hemodynamics, oxygen transport, and nitric oxide
The microcirculation is a complex and integrated system that supplies and distributes oxygen throughout the tissues. The red blood cell (RBC) facilitates convective oxygen transport via co-operative binding with hemoglobin. In the microcirculation oxygen diffuses from the RBC into neighboring tissues, where it is consumed by mitochondria. Evidence suggests t

12. Microvascular changes explain the "two-hit" theory of multiple organ failure.
OBJECTIVE: The objective was to determine intestinal microvascular endothelial cell control after sequential hemorrhage and bacteremia. SUMMARY BACKGROUND DATA: Sepsis that follows severe hemorrhagic shock often results in multiple system organ failure (MSOF) and death. The sequential nature of this clinical scenario has led to the idea of a "two-hit" theory
