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...

o-Xylylenebis (triphenylphosphonium peroxymonosulfate) (1) was easily prepared from an aqueous solution of oxone and o-xylylenebis- (triphenylphosphonium bromide). This Compound (1) is a useful and selective reagent for conversion of oximes, semicarbazones and phenylhydrazones to the corresponding carbonyl compounds. The reaction was carried out under solvent-free conditions and in the presence...

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 ...

The monomeric aluminium hydrazide H10 C5 NN(AltBu2 )Ad (4; Ad=adamantyl, NC5 H10 =piperidinyl) was obtained in high yield by hydroalumination of the corresponding hydrazone derivative 1. Compound 4 has a strained AlN2 heterocycle formed by a donor-acceptor bond between the β-nitrogen atom of the hydrazide group and the aluminium atom. Opening of this bond resulted in the formation of an activ...

The subject of research was groundwater from Quaternary formations with high concentration of total iron, increased colour and turbidity, and an increased amount of organic substances and manganese. Successful purification of such water creates technological problems and is practically impossible to achieve by applying traditional groundwater treatment processes. One of the ways recommended for...

Some new compounds of aluminium having the general formula AI[SC(6)H(4)N:C(R) CH(2) C(O)R'](3) where R = CH(3), R' = CH(3) (1); R' = CH(3), R' = C(6)H(5) (2); R = CF(3), R' = -C = CH - CH = CHS (3); R = CF(3), R' = C(6)H(5) (4) have been synthesised by the reactions of Al(OPr(i))3 and the corresponding ligands in 1:3 molar ratios in benzene. Elemental and spectroscopic (IR, (1)H, (13)C, and (27...

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...

Due to the practical and technical importance of aluminium alkyls, their behaviour towards the components of air is of fundamental interest. The interaction with dioxygen has been studied quite extensively over a period of several decades [1]. In a recent contribution to this field Lewiński and co-workers reported the insertion of oxygen into AlÐC bonds resulting in alkoxide aggregates, but als...
