Collecting blood on ice for renin determination reportedly may produce falsely high results. To assess the probability of this occurring under actual collection conditions, we measured renin activity in duplicate aliquots of plasma from blood samples from 25 hypertensive patients, both supine and upright, and in 10 supine normotensive controls. One aliquot of the blood was collected on ice and ...

background: periodontitis is a multifactorial chronic inflammatory disease characterized by destruction of tooth-supporting tissues. environmental and genetic factors as well as the immune system participate in this process. recent studies have attempted to elucidate the role of cytokine networks involved in periodontal diseases. objective: to assess and compare the levels of il-4, il-6 and il-...

researchers and coaches are constantly looking for the most effective ways to enhance athletic performance. the aim of this study was to investigate the response of strength, power and muscle endurance to resistance training with different rest intervals. 16 male volunteers were selected and divided randomly into two groups. group a (n=8, age 22±2.55 yr, height 174.20±6.14 cm, weight 64.20±6.33...

OBJECTIVE To evaluate the effect of maternal diabetes on the blood pressure and kidney function of female offspring, as well as if such changes exacerbate during pregnancy. METHODS Diabetes mellitus was induced in female rats with the administration of streptozotocin in a single dose, one week before mating. During pregnancy, blood pressure was measured through plethysmography. On the 20th da...

introduction: preventing and starting early treatment of infections in patients whose immunity system is weak due to malignancies like leukemia can reduce mortality. this study aimed to determine microbial and antibiotic resistance patterns in clinical samples of patients with acute leukemia to start early treatment before the results of clinical tests are known. subjects and methods: in this c...

Six mixed-breed apparently healthy dogs were intravenously administered a single dose of tetracycline hydrochloride (50 mg/kg) to evaluate the pharmacokinetic parameters of the drug. Blood samples were collected before and at various time intervals after the administration of the drug. Serum tetracycline concentrations were determined over a 24 h period using fluorescence spectrophotometry. Non...

the objective of this experiment was comparison blood serotonin levels in ascetic and non ascitic broilers of three strains (ross, arbor acres plus and cobb). to this purpose, a factorial test in crd was applied. in each of these three strains, 12 ascitic and 12 non ascitic broilers were selected. after tagging and blood sampling, all of blood samples were divided in two parts. one part was app...

Methods Cross-sectional retrospective study determining: 1) serum adalimumab (Ada) levels by a capture ELISA (positive > 5 ng/ml) and 2) levels of AAA by a two-site bridging ELISA [positive > 10 Arbitrary Units (AU)/ml]. The clinical activity was assessed by conventional tests and the physician visual analogue scale (ph-VAS) of 0 to 10, the same day that the blood sample was collected. Blood sa...

OBJECTIVE Single dose of systemic antibiotics and short-term use of mouthwashes reduce bacteremia. However, the effects of a single dose of preprocedural rinse are still controversial. This study evaluated, in periodontally diseased patients, the effects of a pre-procedural mouth rinse on induced bacteremia. MATERIAL AND METHODS Systemically healthy individuals with gingivitis (n=27) or perio...
