Kreuz, Leo E. (The Johns Hopkins University School of Medicine, Baltimore, Md.), and Allan H. Levy. Physical properties of chick interferon. J. Bacteriol. 89:462-469. 1965.-The sedimentation coefficient, diffusion coefficient, and molecular weight of chick-embryo interferon were determined by zone centrifugation and equilibrium sedimentation in cesium chloride density gradients, and by chromato...
To study grain quality traits and their relationships with high molecular weight (HMW) and low moleculor weight (LMW) glutenin subunits, 104 durum wheat genotypes were used. Six grain quality characteristics comprising wet and dry gluten content, test weight, grain hardiness, protein content and SDS sedimentation volume were studied. HMW and LMW glutenin subunits were evaluated using SDS-polyac...
Determination of the stoichiometry of macromolecular assemblies is fundamental to an understanding of how they function. Many different biophysical methodologies may be used to determine stoichiometry. In the past, both sedimentation equilibrium and sedimentation velocity analytical ultracentrifugation have been employed to determine component stoichiometries. Recently, a method of globally ana...
Serum C-reactive protein (CRP) and the erythrocyte sedimentation rate (ESR) were compared in 241 patients with rheumatoid arthritis (RA). There was a positive linear correlation between the 2 measurements with a high degree of variability. Neither age nor duration of RA had a detectable influence. The relationship between CRP and ESR was, however, altered by treatment with gold, penicillamine, ...
Electrophoretic studies and erythrocyte sedimentation rate measurements were carried out on normal and pathological human blood. An increase in alpha globulin levels appears to take place, as well as an increase in sedimentation rates, when there is present any considerable inflammation or tissue destruction, irrespective of its cause. A graphic correlation is presented between sedimentation ra...
The viscosity of the plasma was studied briefly by Fahraeus in his original investigations (1921) into the blood sedimentation rate. In 1940 further studies were made by T'Ang and Wang, who concluded that it gave a more accurate picture of the activity of disease processes than the erythrocyte sedimentation rate. The plasma viscosity technique was independently developed by Whittington and his ...
BACKGROUND Bleach-sedimentation may improve microscopy for diagnosing tuberculosis by sterilising sputum and concentrating Mycobacterium tuberculosis. We studied gravity bleach-sedimentation effects on safety, sensitivity, speed and reliability of smear-microscopy. METHODS This blinded, controlled study used sputum specimens (n = 72) from tuberculosis patients. Bleach concentrations and expos...
