To achieve cellular iron deprivation by chelation, it is important to develop chelators with selective metal-binding properties. Selectivity for iron has long been the province of certain oxygen-donor chelators such as desferrioxamine, which target Fe(III) and exploit the strength of a relatively ionic Fe(III)-O interaction. We have been studying novel chelators that possess mechanisms to selec...

We investigate the equation (ut + (f(u))x)x = f (u)(ux)/2 where f(u) is a given smooth function. Typically f(u) = u/2 or u/3. This equation models unidirectional and weakly nonlinear waves for the variational wave equation utt − c(u)(c(u)ux)x = 0 which models some liquid crystals with a natural sinusoidal c. The equation itself is also the Euler-Lagrange equation of a variational problem. Two n...

There is increasing interest in the stabilization of heavy metals in road-derived sediments (RDS), to enable environmentally responsible reuse applications and circumvent the need for costly landfill disposal. To reduce the mobility of heavy metals (i.e. Cu, Pb and Zn) the effectiveness of amendments using phosphate, compost and fly ash addition were investigated using batch leaching experiment...

Due to the scarcity of water, raw sewage effluents are often used irrigate arable suburban soils in developing countries, which causes soil contamination with toxic metals. Soil microorganisms involved biochemical transformations sensitive heavy metals contamination. The study was designed investigate effect organic amendments on microbial activity cadmium (Cd), lead (Pb) and zinc (Zn) fraction...

INTRODUCTION AND OBJECTIVE The level of trace elements is extremely important for the maintenance of normal functioning of the human body. The risk of disturbance of their balance increases especially dynamically during the period of menopause. The objective of the study was the effect of MHT on the levels of bioelements (Mg and Zn) in blood plasma, and toxic metals (Pb and Cd) in the whole blo...

The application of micronutrient supplements such as fertilizer, animal manure and sewage sludge in bid to enhance soil productivity and crop yield, poses the risk of heavy metals elevation and nutrients depletion in arable lands. Arable soils were collected from farmlands in use for the cultivation of food produce in selected farming communities in South Western Nigeria. The soils were air-dri...

background: the purpose of this study was to evaluate the levels of zinc (zn), copper (cu), iron (fe) and zinc/ cop­per ratio in the serum of patients with cutaneous leishmaniasis in qom province, center of iran. methods: serum levels of zinc and copper were determined by flame atomic absorption spectrophotometer and serum iron concentration was measured by using an auto analyzer. the study gro...
