Introduction: The bacterial Asparaginase is used in the treatment of asparagine-dependent tumors, particularly lymphatic sarcoma and acute lymphoblastic leukemia. However, the instability of the enzyme increases the number of injections that are accompanied by high immune responses. The aim of this study was to investigate the conjugation of L-asparaginase with nanochitosan glutaraldehyde (NCG)...

We re-visit previous analyses of the classical Michaelis-Menten substrate-enzyme reaction and, with the aid of the reverse quasi-steady-state assumption, we challenge the approximation d[C]/dt approximately 0 for the basic enzyme reaction at high enzyme concentration. For the first time, an approximate solution for the concentrations of the reactants uniformly valid in time is reported. Numeric...
the present study was carried out to investigate the effects of different levels of canola meal eithr with or without phytase addition on laying hen's performance. a number of 288 layer hens (the strains of hy-line w36) at the 60th week of age, selected as based on the same egg production percentage and body weight were, assigned to a factorial arrangement with a completely randomized desi...
abstract because of relation between digestive enzyme activity and feeding of insects that directly is in relation with the damage of insects; studying digestive enzyme systems is important in finding new control methods based on inhibiting digestive enzyme activity. recently using transgenic plants containing enzyme inhibitors is important in improving resistance of crops to pests because of s...
