Chemical Controls on the Formation of Amorphous and Crystalline Calcium Phosphates
… calcium phosphate (ACP) and brushite into hydroxylapatite, an important biomineral, has been documented. The relationships between synthesis conditions and the formation and transformation of these phases are not comprehensively understood. The metastable nature of ACP has made it …

Halo-fosfatų 31P, 1H ir 35Cl kietojo kūno BMR tyrimas /
… it was found that surface phosphates and calcium hydroxylapatite (Ca5(PO4)3OH) were present in calcium chlorapatite (Ca5(PO4)3Cl) samples. The presence of calcium hydroxylapatite can be explained using the fact, that synthesis was performed in air atmosphere and inert conditions were not ensured. …

PURIFICATION OF THE REGULATORY SUBUNIT OF RIBONUCLEOSIDE DIPHOSPHATE REDUCTASE FROM CALF THYMUS
… Concentration by chromatography on a column of hydroxylapatite gave an essentially quantitative yield of purified B1 subunit.</p><p>While no further purification was conducted on the B2 subunit, its molecular weight and Stokes' radius were determined by gel filtration on columns of Biogel A 1.5 …

Treponema hyodysenteriae: growth and production of hemolysin
… the hemolytic activity was recovered. Although, hydroxylapatite adsorption and polyethyleneimine precipitation completely adsorbed or precipitated hemolytic activity I I was unable to efficiently recover the activity. Partially purified hemolysin was c}10toxic to CHO cells, and caused lysis …

Purification of glycoproteins from herpes simplex virus
… proteins from the glycoprotein solutions. Hydroxylapatite (HAUltrogel) chromatography in the presence of sodium dodecyl sulphate (SDS-HTP) did not separate the different HSV-1 glycoproteins and was not satisfactory for removing the non-glycosylated proteins. Gel-bound lectin affinity …

Investigation of the potential beneficial effects of supplemental polyunsaturated fatty acids and glycosaminoglycans on the risk factors for calcium oxalate kidney stone formation using theoretical, experimental and human models
… values for brushite, tribasic calcium phosphate, hydroxylapatite and octacalcium phosphate decreased significantly in black subjects after CS supplementation, whereas the SS value for hydroxylapatite increased significantly in the white group. These effects could not be attributed to complexation …

Carboxyl Methylation of Non-Histone Chromosomal Proteins
… the NHCP were separated from histones on hydroxylapatite, and fractionated further on SDS acrylamide slab-gel electrophoresis. After the gels were dried, autoradiography was used to detect <sup>3</sup>H-methyl groups associated with these proteins. Four NHCP from the liver and thymus were …

Les iguanodons de Bernissart: leur évolution diagénétique et les processus de dégradation
… took place: the slightly crystallized carbonated hydroxylapatite (the mineral phase of fresh bone tissue) was replaced by well crystallized carbonated fluorapatite currently present in the Iguanodon bones. Whereas some minerals infiltrated in the bone during cavity filling by the sediment …

Replication of bovine parvovirus
… dodecyl sulfate (Hirt procedure) followed by hydroxylapatite chromatography. Some of the molecules of DNA isolated in this way existed in a covalently closed circular configuration as demonstrated by rapid reannealing rates following thermal denaturation, In addition, agarose gel …

Tumor-induced immunosuppression: Contribution of a high molecular weight inhibitor and Prostaglandin E2
… Normal and TBH Mφ supernatants showed different hydroxylapatite fractionation, with the latter being resistant to proteolytic enzymes but sensitive to neuraminidase. Lectins such as wheat germ agglutinin, concanavalin A, Ricin communi: and Bandeirea simplicifolia were not useful in affinity …

Developing a Drug Delivery System for Treatment of Vocal Fold Scarring
… materials, such as hyaluronic acid or calcium hydroxylapatite. These solutions do not actually treat the actual scar, but only relieve its effects over the short term seeing as current injectable materials readily degrade.</p> <p>To solve this problem researchers have been testing the impact …
