Hydrodynamic drag during gliding in swimming

Validation of water and land anaerobic tests using Wingate Test as a gold standard

Fatigue thresholds in 30s water and land exercises performed by swimmers

Time limit at VO2max velocity in elite crawl swimmers

he purpose of this study is to assess, with elite crawl swimmers, the time limit at the minimum velocity corresponding to maximal oxygen consumption (TLim-vVO2max), and to characterize its main determinants. Eight subjects performed an incremental test for vVO2max assessment and, forty-eight hours later, an all-out swim at vVO2max until exhaustion. VO2 was directly measured using a telemetric portable gas analy...

Equidade no acesso ao transplante renal em Belo Horizonte, 2000-2005

Background: The world growth in the number of patients with Chronic Renal Failure has reached epidemic rates. Only by using renal replacement therapies (dialysis) or renal transplantation, the patients survival is possible. The renal transplantation is the choice treatment: it offers better survival and quality of life and it is also more cost effective than dialysis. Brazil has the greatest public health trans...

Evaluation of the genotoxic potential of the Hypericum brasiliense (Guttiferae)...

Plants of the genus Hypericum, long used in folk medicine, contain active compounds which present, anti-septic, diuretic, digestive, expectorant, vermifugal, anti-depressive and other properties. The possible clastogenic effect of a H. brasiliense extract was tested in vivo on the bone marrow cells of Wistar rats. The extract was administered by gavage at doses of 50, 150 and 300 mg/kg body weight. Experimental...

Especiação analítica de compostos de arsênio empregando métodos voltamétricos e...

This paper provides a review on voltammetric and polarographic methods for the speciation analysis of inorganic and organic arsenic compounds in different matrices. A discussion on the main advantages of electroanalytical methods in comparison with other analytical methods employed for arsenic speciation is presented. The mechanistic aspects of the most relevant techniques employing cathodic and anodic strippin...
