Platelet adherence surrounding leucocytes in a rosette formation or platelet satellitism is a rare phenomenon. This finding has been observed almost exclusively in Ethylenediaminetetraacetic acid treated blood at room temperature. The mechanism underlying this phenomenon is not fully understood. In many reports of platelet satellitism platelets clump to polymorphonuclear neutrophils in healthy...

Morphological changes and the content of free carboxyl groups in bovine collagen (type I) film under the influence of trypsin, hydrochloric acid (HCl) and ethylenediaminetetraacetic acid (EDTA) were studied. Incubation with trypsin and HCl was found to cause some delamination of the film and the appearance of some low-density spots. Incubation with EDTA did not cause any morphological changes. ...

Under proper conditions, one infective center was obtained for 3 X 108 molecules of P22 phage deoxyribonucleic acid (DNA) when lysozyme-ethylenediaminetetraacetic acid spheroplasts of Escherichia coil were transfected in the presence of 25 /Ig of protamine sulfate per ml. A 3to 50-fold B-specific and K-specific E. coli restriction of the incoming P22 DNA was observed. When P22 DNA-infected E. c...

Effect of different type of organic compounds (humic acid, oxalate, ethylenediaminetetraacetic acid, nitrilotriacetic acid, phenol) on the photocatalytic removal of cyanide with TiO2 or ZnO was studied in this work with variation of the solution pH, contact time, initial cyanide concentration and type of organic compounds. Photocatalytic oxidation efficiency of cyanide with TiO2 was greatly aff...
