Background & Aim:The main aim of this study was stabilizing D. Sophia beverage and reduce its sedimentation rate. Experimental: Xanthan and Carboxy methyl cellulose gums have been used in three levels (0.05, .01 and .02 gr/lit) and mixture of Guar-xanthan and carboxymethyl cellulose (each .1 g/l) and extracted dried gum from D. Sophia in (1, 2 an...

Anticoagulant therapy has been employed in thromboembolic disease with increasing frequency during the past few years. There has been a striking lack of unanimity in the literature (1 to 15) as to the effect of heparin or dicumarol per se upon the erythrocyte sedimentation rate. In view of the fact that anticoagulants are frequently employed in disorders in which the sedimentation rate is of im...

Analytical ultracentrifugation is one of the classical techniques for the study of protein interactions and protein self-association. Recent instrumental and computational developments have significantly enhanced this methodology. In this paper, new tools for the analysis of protein self-association by sedimentation velocity are developed, their statistical properties are examined, and consider...

Sedimentation and movement of plastids in columella cells of the root cap were measured in seedlings of wild-type, a reduced starch mutant, and a starchless mutant of Arabidopsis. To assay for sedimentation, we used both linear measurements and the change of angle from the cell center as indices in vertical and reoriented plants with the aid of computer-assisted image analysis. Seedlings were f...
