Immobilization of starch phosphorylase from cabbage leaves: production of gluco...
Garg,N.; Kumar,A.Starch phosphorylase has been isolated from cabbage (Elephantopus scabar) leaves and partially purified using ammonium sulfate fractionation. The partially purified enzyme was desalted using Sephadex-G-25 chromatography. In the direction of polysaccharide synthesis, the enzyme showed optimum activity at pH 6.0 with two half pH optima at pH 5.3 and pH 7.1 whereas in the direction of glucose-1-phosphate formation...
Synthesis and characterization of rice husk silica, silica-carbon composite and...
Singh,D.; Kumar,R.; Kumar,A.; Rai,K. N.This paper discusses synthesis and characterization of (i) rice husk based nanosilica, (ii) nanosilica carbon composite granules and (iii) phosphoric acid activated ash silica. These have been produced by burning husk in air, charring husk in hydrogen and activating husk silica with H3PO4 respectively. X-ray diffraction studies of these products reveal increasing peak width (amorphosity) with decreasing burning...
alpha-Tocopherol enhances tumour growth inhibition by cis-dichlorodiammine plat...
Sarna,S.; Kumar,A.; Bhola,R.K.Present studies indicate that alpha-tocopherol enhances the efficacy of cisplatin as demonstrated by inoculation of Dalton's lymphoma cells incubated with either cisplatin (5 or 10 µg/ml) alone or cisplatin + alpha-tocopherol (25 or 50 µg/ml) into C3H/He mice. Tumour cells (3 x 10(6) cells/mouse) incubated with cisplatin grow slowly in syngeneic mice as indicated by the late appearance of tumour. However, mice ...
