background: aluminum phosphide (alp) or rice tablet is a common agent used as pesticides. it is cheap, widely available and highly toxic and responsible for many cases of poisoning in the agricultural communities. there is limited evidence about change of liver enzymes in patients with alp poisoning in this region. therefore, we decided to evaluate alteration of liver enzymes in alp poisoning i...

INTRODUCTION Aluminium is a known neurotoxin and occupational exposure to aluminium has been implicated in neurological disease including Alzheimer's disease. Here we present the first comprehensive and unequivocal data demonstrating significantly elevated brain aluminium content in an individual occupationally exposed to aluminium. CASE PRESENTATION A 66-year-old Caucasian man who died with ...

Currently available semiconductor lasers for spectroscopy in the near- and mid-infrared region based on direct band-to-band transitions as gallium-arsenide, indium-phosphide, antimonides and lead-salt containing compounds will be discussed together with the main features of different tunable diode-laser absorption spectrometers for trace gas analysis. Measurements of atmospheric carbon dioxide ...

The efficacy of aluminum phosphide was tested on a total of 300 active black-tailed prairie dog (Cynomys ludovicianus) mounds and 68 active'yellow-faced pocket gopher (Pappogeomys castanops) tunnels during June-August, 1986 on the southern Great Plains in Lubbock County, Texas. Efficacy of aluminum phosphide was higher than controls (P < 0.001) for both species. Efficacy was higher for black-ta...

The reactivity of the 2-phosphaethynolate anion (PCO(-)) towards a cyclic trisilene (cSi3(Tip)4) is reported. The result is the net activation of the P-C and Si-Si multiple bonds of the precursors affording a heteroatomic bicyclo[1.1.1]pentan-2-one analogue ([P(CO)Si3(Tip)4](-); 1). This reaction can be interpreted as the formal addition of a phosphide and a carbonyl across the Si-Si double bon...

We demonstrate that highly tunable nanowire arrays with optimized diameters, volume fractions, and alignment form one of the strongest optical scattering materials to date. Using a new broad-band technique, we explore the scattering strength of the nanowires by varying systematically their diameter and alignment on the substrate. We identify strong Mie-type internal resonances of the nanowires ...

Layers of palladium (Pd) nanoparticles on indium phosphide (InP) were prepared by electrophoretic deposition from the colloid solution of Pd nanoparticles. Layers prepared by an opposite polarity of deposition showed different physical and morphological properties. Particles in solution are separated and, after deposition onto the InP surface, they form small aggregates. The size of the aggrega...

Urinary excretion of aluminium after a successful transplant can reverse pre-transplant aluminium intoxication. We have evaluated the time course of urinary aluminium excretion and its correlation with several parameters of renal function and mineral metabolism in 49 patients (33 men and 16 women) with a wide range of pre-transplant serum aluminium concentrations, performing sequential determin...

The Kaidun meteorite, which fell on 3.12.1980 at lat. 15° N, long. 48.3° E, holds a special place in the world meteorite collection. Kaidun is characterized by an unprecedentedly wide variety of meteorite material in its makeup. The high degree of variability in this meteorite’s material is evidenced by the richness of its mineral composition – nearly 60 minerals and mineral phases have been id...
