1. Serum 25-hydroxyvitamin D levels in patients with Granulomatosis with Polyangiitis: association with respiratory infection
OBJECTIVES: To determine the possible association of serum 25-hydroxyvitamin D (25OHD) levels with disease activity and respiratory infection in granulomatosis with polyangiitis patients during two different periods: winter/spring and summer/autumn. METHODS: Thirty-two granulomatosis with polyangiitis patients were evaluated in the winter/spring, and the s

2. In vitro culture and characterization of alveolar bone osteoblasts isolated from type 2 diabetics
In order to understand the mechanisms of poor osseointegration following dental implants in type 2 diabetics, it is important to study the biological properties of alveolar bone osteoblasts isolated from these patients. We collected alveolar bone chips under aseptic conditions and cultured them in vitro using the tissue explants adherent method. The biologic

3. AVALIAÇÃO DA CITOTOXICIDADE, CITOPROTEÇÃO E EFEITOS DOS FLAVONÓIDES RUTINA E HESPERIDINA SOBRE A FUNCIONALIDADE DE CÉLULAS SECRETORAS DE INSULINA BRIN-BD11
Diabetes mellitus is now a major public health problems, with increasing numbers of incidence, and has been considered an epidemic. Several studies demonstrate the relationship between diabetes mellitus and oxidative stress. Thus bioactive compounds with potential to act by preventing or mitigating the consequences of this process are interesting. In this ca

4. Hemodynamic, morphometric and autonomic patterns in hypertensive rats - renin-angiotensin system modulation
BACKGROUND: Spontaneously hypertensive rats develop left ventricular hypertrophy, increased blood pressure and blood pressure variability, which are important determinants of heart damage, like the activation of renin-angiotensin system. AIMS: To investigate the effects of the time-course of hypertension over 1) hemodynamic and autonomic patterns (blood pres

6. Estudo do metabolismo, quimica e farmacocinetica do principal metabolito da diidroergocristina / Metabolic, chemical and pharmacokinetics of the main diidroergocristine metabolite
Dihydroergocristine (DHEC) is a semi-synthetic drug mainly used for migraine and studied in age-related cognitive impairment. In this study, its major metabolite 8´-hydroxy-dihydroergocristine (8´-OH-DHEC) was produced in incubates of a bovine liver preparation using dihydroergocristine mesylate (DHECM) as substrate. An evaluation of the best enzymatic pre

8. relação entre a concentração plasmática do peptídeo natriurético tipo b, índice cardiofemoral e equilíbrio ácido-básico em fetos de gestantes isoimunizadas
Introduction: Fetal anemia is a common result of alloimunization and is an important cause of fetal congestive heart failure resulting in heart dilation. Fetuses suspected of having heart failure present a higher cardiofemoral index and an increase in plasma BNP levels, because the cardiac hormonal system is activated by increased heart wall stretch due to i

9. Development of methods to access phospholipase A2 fraction activity in platelets / "Desenvolvimento de métodos para determinação da atividade das frações da fosfolipase A2 em plaquetas"
Phospholipase A2 (PLA2) is a key-enzyme in the metabolism of membrane phospholipids and is one of the major components involved in cell signaling. Alterations of PLA2 activity have been reported in brains and blood cells in several neuropsychiatric diseases. In this study we developed a radio-enzymatic assay to detect in platelets the activity of the three m

10. Quantification of fecal estradiol and progesterone metabolites in Syrian hamsters (Mesocricetus auratus)
Alternative methods to the utilization of laboratory animal blood and its by-products are particularly attractive, especially regarding hamsters due to their small size and difficulties in obtaining serial blood samples. Steroid hormone metabolite quantification in feces, widely used in studies of free-ranging or intractable animals, is a non-invasive, non-s

11. Myocardial antioxidant and oxidative stress changes due to sex hormones
The purpose of the present study was to examine myocardial antioxidant and oxidative stress changes in male and female rats in the presence of physiological sex hormone concentrations and after castration. Twenty-four 9-week-old Wistar rats were divided into four groups of 6 animals each: 1) sham-operated females, 2) castrated females, 3) sham-operated males
