The Mutagenic Activity of Chitosan and its Effect on the Growth of Trichoderma harzianum and Fusarium oxysporum F. Sp. Sesami
by: shinta, 6 pagesFive concentrations of chitosan; 0.38, 0.75, 1.50, 3.00 and 4.50 mg/ml were used to study its effect on the growth of Fusarium oxysporum f sp. Sesami and Trichoderma harzianum. Chitosan ...
Chitosan : A potential biomaterial effective against typhoid
by: shinta, 3 pagesChitin, a polysaccharide of animal origin, is obtained from waste material of seafood industries. It occurs in the skeletal mate- rial of crustaceans such as crabs, lobsters, ...
Studies on the Degradation Behavior of Chitosan-g-Poly (acrylic acid) Copolymers
by: shinta, 7 pagesGraft copolymers of Chitosan and poly(acrylic acid) were synthesized with a redox initiator, cerium ammonium nitrate. After 2 h of reaction at 70oC, a gel product was obtained. The ...
Functional Characterization of Chitin and Chitosan
by: shinta, 28 pagesChitin and its deacetylated derivative chitosan are natural polymers composed of randomly distributed ß-(1-4)- linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine ...
In Vitro Cytotoxicity and Protein Drug Release Properties of Chitosan / Heparin Microspheres
by: shinta, 5 pagesChitosan/heparin microspheres were prepared using the water-in-oil emulsification solvent evapo- ration technique. The microsphere diameters were controlled by selecting the fabrication process ...
The Controlled Release of a Drug from Biodegradable Chitosan Gel Beads
by: shinta, 3 pagesChitosan (CS) forms a gel in solutions with a pH above 12, and the gelation occurs at pH of about 9 in 10% amino acid solutions. In this paper, we investigated the enzymatic degradation and the ...
The role of a mixture of green tea, turmeric and chitosan in the treatment of obesity-related testicular disorders
by: shinta, 8 pagesIn the present investigation, we studied the effect of aqueous green tea extract (GTE), alcoholic turmeric extract (ATE), and water-soluble Chitosan (WSC), individually/or in mixture, on the
Effects of incorporation of poly (g-glutamic acid) in chitosan / DNA complex nanoparticles on cellular uptake and transfection efficiency
by: shinta, 12 pagesChitosan (CS)/DNA complex nanoparticles (NPs) have been considered as a vector for gene delivery. Although advantageous for DNA packing and protection, CS-based complexes may lead to ...
Chemical composition and sorption properties of chitosan produced from fly larva shells
by: shinta, 7 pagesChitosans recovered from fly larva shells have been investigated by the elemental analysis, potentiometric titration and FT-IR spectrometry methods. The molecular weight of chitosans was ...
Stabilization of Papain by Modification with Chitosan
by: shinta, 6 pagesPapain (EC 3.4.22.2) was immobilized on chitosan by adsorption and subsequent cross-linking with glutaraldehyde. The immobilized papain displayed a lower specific activity than did the native ...
