Hybrid pigments based on carminic acid (CA) stabilized by clay minerals have been prepared. Three different pathways were used: [email protected]; protected] saponite; and hydrogels of saponite-CA or montmorillonite-CA covered polyorganosilane (POS). Pigments characterized a set techniques including X-Ray diffraction (XRD), transmission electron microscopy (TEM), infrared spectroscopy (FTIR), s...
PURPOSE The present study examined the factors affecting the content of impurities of nimodipine (NMP) emulsion and the associated methods of compound protection. METHODS Destructive testing of NMP emulsion and its active pharmaceutical ingredient (API) were conducted, and ultracentrifugation was used to study the content of impurities in two phases. The impurity of NMP was measured under dif...
1. Cyst walls of the beet cyst-nematode (Heterodera schachtii Schmidt) were obtained by sieving a suspension of crushed cysts; about 15mg of dried cyst walls was obtained from 1000 cysts. 2. The cyst walls contained 68% protein calculated from nitrogen content. Glutamic acid, glycine, proline and hydroxyproline made up about 54% by weight of the amino acids obtained on acid hydrolysis. 3. Minor...
In previous papers (McMurray, Strickland, Berry & Rossiter, 1957b; McMurray, Berry & Rossiter, 1957a) two systems capable of supporting the incorporation of inorganic 32p into the phospholipids of rat-brain dispersions were described: (a) an anaerobic system (best demonstrated in hypotonic dispersions), which supported the labelling of lipid P under optimum conditions for glycolysis (McMurray e...
The present study tests the hypothesis that changes in the strong inorganic ion concentrations contribute significantly to the acid-base disturbance that develops during hemorrhage in the arterial plasma of rats in addition to lactate concentration ([Lac-]) increase. The physicochemical origins for this acid-base disorder were studied during acute, graded hemorrhage (10, 20, and 30% loss of blo...
