13. 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

14. Leptin and insulin in the seminal plasma of zebu bulls in peripuberty
In order to determine the profile of leptin and insulin values in seminal plasma and their correlations with sperm patterns during the peripuberty, a total of 16 crossbred Gyr dairy bulls were monitored from 60 days before to 60 days after puberty, separated into two groups, early and regular, according to the onset of puberty. Hormone values were determined

15. Influência dos hormônios sexuais na analgesia induzida pelo estresse / Influence of sex hormones in stress-induced analgesia
Temporomandibular disorders comprehend a variable group of conditions which result in joint and/or muscle pain and contribute to the development of acute pains, being more prevalent in women than men, especially during the reproductive period. They involve the muscles of mastication and temporomandibular joint (ATM), being usually associated with inflammator

16. 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

17. Correlation between sperm characteristics and testosterone in bovine seminal plasma by direct radioimmunoassay
The objectives of this study were to validate a non-extractive RIA for seminal testosterone and quantify the hormone using a solid-phase commercial kit, and study the correlation between testosterone in seminal plasma and sperm characteristics. Parallelism showed a correlation index r = 0.992 (Y = -5.47 + 1.073X; R² = 0.985), indicating that the non-extract

18. The effect of down-regulation of Smad3 by RNAi on hepatic stellate cells and a carbon tetrachloride-induced rat model of hepatic fibrosis
Searching for effective Smad3 gene-based gene therapies for hepatic fibrosis, we constructed siRNA expression plasmids targeting the rat Smad3 gene and then delivered these plasmids into hepatic stellate cells (HSCs). The effect of siRNAs on the mRNA levels of Smad2, Smad3, Smad4, and collagens I-α1, III-α1 and IV-α1 (Colα1, Col3α1, Col4α1, respectivel

19. Estradiol-induced hypophagia is associated with the differential mRNA expression of hypothalamic neuropeptides
Estradiol participates in the control of energy homeostasis, as demonstrated by an increase in food intake and in body weight gain after ovariectomy in rats. In the present study, female Wistar rats (200-230 g, N = 5-15 per group), with free access to chow, were individually housed in metabolic cages. We investigated food intake, body weight, plasma leptin l

20. Determination of free urinary cortisol in cushing's syndrome using reversed-phase high performance liquid chromatography
Determination of free urinary cortisol is a test of choice in the diagnosis of Cushing's syndrome. In this study, cortisol was quantified using reversed-phase high-performance liquid chromatography (RP-HPLC) in urine samples previously extracted with ether and using triamcinolone acetonide as internal standard (IS). A BDS-Hypersil-C18® column, water-acetoni

21. 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

22. Glutamic acid decarboxylase antibodies are indicators of the course, but not of the on-set, of diabetes in middle-aged adults: the atherosclerosis risk in communities study
To efficiently examine the association of glutamic acid decarboxylase antibody (GADA) positivity with the onset and progression of diabetes in middle-aged adults, we performed a case-cohort study representing the ~9-year experience of 10,275 Atherosclerosis Risk in Communities Study participants, initially aged 45-64 years. Antibodies to glutamic acid decarb
