This study has attempted to establish an analysis method through validation against heavy metals in the body (Pb, Cd and Hg) using ICP-MS and Gold amalgamation and find out the relevance between heavy metal and Alzheimer's disease after analyzing the distribution of heavy metal concentration (Pb, Cd and Hg) and correlations between a control group and Alzheimer's disease group. In this study, P...

Exposing native calf thymus DNA (in 0.1 M NaClO4, 5 mM cacodylic acid buffer, pH 6.81, 25 degrees C) to increasing concentrations of Hg(ClO4)2 produces dramatic changes in its circular dichroism (CD). Let r = [mol of added Hg(II)*/[mol DNA base]: the conservative CD spectrum of the DNA B-form, consisting of the 273 nm major (+) CD band, the 245 nm major (-) CD band, the 219 nm minor (+) CD band...

Purpose: The aim of this study is to develop bromhexine hydrochloride 1 %w/v oral solution for veterinary use and to evaluate its stability. Methods: Solutions of Bromhexine hydrochloride (1%w/v) were prepared by dissolving bromhexine hydrochloride in benzyl alcohol at 50 °C then alcohol 96 % v/v; Tween 80 and purified water were added. The obtained solution was filled in amber glass bottles, a...

Surveillance for mercury (Hg), lead (Pb) and cadmium (Cd) contamination in tuna products is crucial for consumer food safety. Hg, Pb and Cd contaminants were monitored in a total of 60 specimens of fresh little tunny (Euthynnus alletteratus) and popular brands of skipjack and yellowfin (Katsuwonus pelamis and Thunnus albacares) canned tuna commercially available in Tripoli, Libya. Direct Mercur...

the task specific ionic liquid (tsil), tricaprylmethylammonium thiosalicylate ([a336][ts]),was synthesized, characterized and subsequently used as extraction solvent in dispersive liquid-liquidmicroextraction (dllme) technique. the tsil-dllme method followed by inductively coupled plasmaatomicemission spectrometry (icp-aes) was applied to determination of trace mercury (hg) and cadmium(cd) in a...
