OBJECTIVE Endothelial dysfunction is an early marker of atherosclerosis seen in type 2 diabetic subjects. Metformin is commonly used in the treatment of type 2 diabetes and has known vasculoprotective effects beyond its hypoglycemic ones. We aimed to investigate the vascular effects of metformin in first-degree relatives with metabolic syndrome of type 2(More)
OBJECTIVES To evaluate changes on cutaneous microangiopathy in chronic venous disorder (CVD) after use of Cirkan [venotonic drug containing Ruscus aculeatus (plant extract), hesperidine methylchalcone (flavonoid) and vitamin C], elastic compression stockings (ECS) or no treatment for four weeks. PATIENTS AND METHODS Fifty-five female patients (85 legs),(More)
OBJECTIVE Capillary recruitment is impaired in obesity (OB), possibly worsening glucose and insulin availability to target organs. In this study, we investigated whether functional microvascular parameters were correlated with clinical-anthropometrical data and whether these parameters would influence OB-related metabolic disorders, especially glucose(More)
BACKGROUND We aimed to evaluate the multivariate association between functional microvascular variables and clinical-laboratorial-anthropometrical measurements. METHODS Data from 189 female subjects (34.0 ± 15.5 years, 30.5 ± 7.1 kg/m2), who were non-smokers, non-regular drug users, without a history of diabetes and/or hypertension, were analyzed by(More)
OBJECTIVE Insulin resistance (IR) is associated with intramyocellular lipid (IMCL) content and low serum adiponectin (ADP) levels and ADP is also involved in muscle fat oxidation. However, the relationship between ADP and IMCL content is still controversial and in this study we explored it further in non-diabetic adults. DESIGN Cross-sectional clinical(More)
Ischemia/reperfusion (I/R) injury can occur in consequence of myocardial infarction, stroke and multiple organ failure, the most prevalent cause of death in critically ill patients. I/R injury encompass impairment of endothelial dependent relaxation, increase in macromolecular permeability and leukocyte-endothelium interactions. Polyunsaturated fatty acids(More)
The leopard cat, Prionailurus bengalensis (Kerr, 1792), is one of the most widespread Asian cats, occurring in continental eastern and southeastern Asia. Since 1929, several studies have focused on the morphology, ecology, and taxonomy of leopard cats. Nevertheless, hitherto there has been no agreement on basic aspects of leopard cat biology, such as the(More)
Basal cell carcinomas are the most common cutaneous neoplasias. They rarely metastasize, but can cause clinically significant local destruction and disfigurement if neglected or inadequately treated. The spectral imaging technique, a recently developed method of orthogonal light polarization, allows in vivo transcutaneous evaluation of tumor(More)
Leprosy is a chronic granulomatous infection of skin and peripheral nerves caused by Mycobacterium leprae and is considered the main infectious cause of disability worldwide. Despite the several studies regarding leprosy, little is known about its effects on microvascular structure and function in vivo. Thus, we have aimed to compare skin capillary(More)
The Paraguayan caiman (Caiman yacare) is the main Caimaninae species occurring in the Brazilian Pantanal Wetland. Despite the relative availability of works focused on biology and conservation of the Paraguayan caiman, almost nothing is known about its vocal structure and behavior. We recorded aggressive calls of adult caiman females guarding nests and,(More)
