A method has been developed for the determination of the following amino acids in 0.1 ml. of blood plasma: alanine, arginine, glutamine, glycine, lysine, serine, taurine, threonine, and valine. A micro Sephadex C-25 column was used to separate the plasma proteins from the amino acids. The amino acid fraction, which is collected in 1 ml. of eluate, is then desalted in an electrolytic desalter, a...

Ultrasonic velocity (u), density (ρ), viscosity (η) and related acoustical parameters such as adiabatic compressibility (β), free energy (∆G), internal pressure (πi), relaxation time (τ) and acoustic impedance (z) have been computed using standard relation for tetra alkyl ammonium cation (Et4N + , Pr4N + , Bu4N + , and Pen4N + ) in binary liquid mixtures of 1, 4 Dioxane and N, N – Dimethyl Form...

The paper presents an ASIC to be used in one of the instruments of Rosetta Lander – a spacecraft that will investigate properties of comet 46 P/Wirtanen nucleus. The Rosettabis chip integrates a number of analog and digital modules of densitometer and thermal conductivity measurement subsystems. In addition to chip architecture and design methodology some problems typical for space application ...

A female frog heterozygous at two unlinked loci, specifying electrophoretic forms of mannosephosphate isomerase (MPI) and malate dehydrogenase (MDH) was crossed to male frogs homozygous for different alleles at each locus. In the offspring approximately ten percent proved to be triploid according to nucleolar and chromosome counts of tail tip cells. Most of these triploids had both maternal all...

Immersion of the intestinal tissue, from rat jejunum, in hypertonic saline produced very rapid changes in all regions of the epithelial cells, but the apical region was apparently unaffected by hypotonic solutions for at least (1/2) hour. In both cases, blistering of the microvilli was taken as the first sign of degenerative changes which finally resulted in a breakdown to large vesicular parti...

A complete study of thermophysical properties concerning the 1,3-dimethyl-2-imidazolidinone (DMI) + water binary system is realized. Density, speed sound, dynamic viscosities, and refractive index measurements have been performed at atmospheric pressure, using a vibrating tube densitometer, falling ball viscosimeter, refractometer for pure DMI, water, aqueous solutions from 278.15 to 323.15 K. ...

Previous studies have demonstrated exercise-induced heat shock protein 70 (HSP70) in animals. The purpose of this study was to investigate human skeletal muscle HSP70 response to rowing training. Ten male rowers trained for 4 wk with different forms, durations, and intensities of exercise. Biopsy was performed in the right musculus vastus lateralis before training and at the end of each week. H...

The small asaccharolytic, nonpigmenting gram-negative rods of the human oral cavity are difficult to differentiate from each other. Protein profiles of sonicated cells of Wolinella species, Campylobacter concisus, Bacteroides gracilis, and Eikenella corrodens were obtained by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and visualized with a silver stain. The gels were scanned with...

Neutron radiography (NR) technique has been adopted to study homogeneity and water absorption behavior of building materials, like double layer silver gray tiles obtained from Concord Real Estate & Building Products, Unit II, Salna, Gazipur, Dhaka, Bangladesh. Measurements of optical density differences between the film background and radiographic images of the dry/wet samples were used for inv...
