The Yanomama Indians are a South American tribe distributed over an irregular area approximately 200 X 300 miles. The gene frequencies observed at 12 loci in 47 villages within this area have been analyzed for the occurrence of clines. Apparently significant clines are observed for alleles of the Rh, MNSs, Kidd, Gm, Inv and serum albumin system. Available data concerning recent tribal expansion...

OBJECTIVE To evaluate the relationship between changes in emulsion globule size distributions and container uptake of lipid emulsions in total nutrient admixtures. METHODS A total nutrient admixture was prepared from a commercial lipid emulsion, 20% ClinOleic®, separated into glass (borosilicate) and ethylene vinyl acetate (EVA) plastic containers, and then stored at ambient conditions for ap...

The effect of maintaining pulmonary nitrogenation on venous admixture during halothane anaesthesia and on postoperative hypoxaemia was studied in patients undergoing either abdominal surgery or the removal of varicose veins. In both groups venous admixture was greater when nitrogen replaced nitrous oxide in the anaesthetic gas mixture. In the varicose vein group hypoxaemia was more severe in th...

Haemodynamic and respiratory data were obtained by gasometric methods in two groups of patients with hepatic cirrhosis, who were distinguishable by the presence or absence of finger clubbing. Cardiac index and venoarterial admixture were significantly higher in cases with clubbing; these findings are discussed. However, levels of venoarterial admixture were normal in four with clubbing, which s...

In this study, it is aimed that production of high performance concrete using admixtures. The admixture is used to resist against to freezing of concrete, and concrete (C20) is produced, and cured in water. 8 samples are tested in pressure, and mean stress is determined as 28 MPa. Remaining two samples are tested with image processing technique, and determined that sample which containing an ad...

Admixture mapping is the first experimentally practical method for carrying out a whole-genome association scan, and is thus a promising method for detecting risk factors for common disease. The goal of the community should now be to aggressively test whether the method is useful in practice for localizing disease genes, by carrying out at least three high-powered studies. We also propose a str...
