1. Free amino acids and ninhydrin-positive substances were studied in blood plasma, erythrocytes, heart and gills of rainbow trout using ion exchange automatic chromatography. 2. In comparison with plasma, only few amino acids have higher levels in red cells: aspartic and glutamic acids, glycine. 3. In heart and gills total amino acid level is greater than(More)
Several lipid parameters were evaluated in 88 patients with acute myocardial infarction (AMI). A reduction in cholesterol and phospholipid level was observed, with minimal values between the days 10-20, followed by a subsequent increase. Triglycerides increased after 12-14 hours, with a maximal value after 20-30 days. Cholesterol bound to high-density(More)
A total of 385 albino Swiss mice, of both sexes, between 24 and 30 hours of age are neonatally thymectomized, by means of a suction pump method. One batch is operated under ether anesthesia, another with sodium pentobarbital, and a third one with Cryoanesthesia. The last batch is subdivided into 2. In one of these the mother is anesthetized with sodium(More)
We report both experimental measurements and molecular simulations of the melting and freezing behavior of simple fluids in porous media. The experimental studies are for carbon tetrachloride and nitrobenzene in controlled pore glass (CPG) and Vycor. Differential scanning calorimetry (DSC) was used to determine the melting point in the porous materials for(More)
Plasmatic levels of total proteins, total lipids, phospholipids, triglycerides, free cholesterol and cholesterol esters, were measured in rainbow trout (Salmo gairdnerii Rich) after adrenaline administration and confronted with control values. A large increase of total lipids concerning all the fractions studied, and specially triglycerides, was noted. The(More)
