the effects of aluminium and aluminium-citrate on some serum parameters related to carbohydrate metabolism in male wistar rats were investigated. daily intraperitoneal administrations of 1 mg/kg body weight of aluminium or aluminiumcitrate (1: 1) for 50 days led to the elevation of serum insulin by 24 or 40 percent respectively, with the concomitant decrease in serum glucose concentrations by 1...

Surface oxygen of oxide catalyst has low coordination number; they are negatively charged. can act active site for decomposition energetic nitramines (i.e. HMX). Additionally hydrous surface release OH radicals. Colloidal particles fulfil these requirements. Furthermore induce thermite reaction with aluminium particles. This study reports on the facile fabrication colloidal ferric 5 nm average ...

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 ...

High-resolution electron microscopy was employed to characterize the interface structure of a cast Al-Mg-Si-Bi-Pb aluminium(6262)-based composite reinforced by alpha alumina particles with a trace of beta alumina in order to investigate the behaviour of alloying elements in cast composites. Except for a few primary Mg2Si particles, few reaction products were detected at the interface of Al/alph...

Interstitial pneumonia develops in association with inhaled particles. In-air microparticle induced X-ray emission (in-air micro) analysis was previously employed to assess the spatial distribution and content of particles in surgical lung biopsy specimens. The aim of this study was to assess the efficacy of in-air micro-analysis for transbronchial lung biopsy specimens in patients with or with...

alumina is one of the most widely used ceramic materials as catalysts, catalyst supports and absorbents, and also wear resistant coating. this study focused on fabricating and characterizing of alumina ceramic nanoparticles fabricated using new and simple sol-gel method. aluminium oxide (al2o3) nanoparticles were synthesized by iron (iii) nitrate 9-hydrate as precursor. physicochemical properti...
