Denesting by Bounded Degree Radicals
Given a nested radical involving only d-th roots we show how to compute an optimal or near optimal depth denesting of this nested radical by a nested radical that involves only D-th roots, where D is an arbitrary multiple of d. As a special case the algorithm can be used to compute denestings as in previous papers by S. Landau and Horng/Huang. The running times of the algorithms are polynomial ...
متن کاملhydrochlorothiazide detection in urine samples by hplc-dad and experimental design dispersive l-l microextraction
hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...

متن کاملProtein Damage and Degradation by Oxygen Radicals
Aggregation, fragmentation, amino acid modification, and proteolytic susceptibility have been studied following exposure of 17 proteins to oxygen radicals. The hydroxyl radical (‘OH) produced covalently bound protein aggregates, but few or no fragmentation products. Extensive changes in net electrical charge (both + and -) were observed. Tryptophan was rapidly lost with ‘OH exposure, and signif...
متن کاملMutagenesis by metal-induced oxygen radicals.
To assess the contribution of reactive oxygen species (ROS) to metal-induced mutagenesis, we have determined the spectrum of mutations in the lacZ alpha gene after exposure of M13mp2 DNA to Fe2+, Cu2+, and Ni2+. With iron and copper ions, mutations are clustered and are predominantly single-base substitutions. Fe, Cu, and phorbol ester-stimulated neutrophils also produced tandem double CC-->TT ...
