To determine the influence of the metal coordination sphere on the permeability of the blood-brain barrier (BBB), rats were injected intraperitoneally with aluminum lactate (Al(lact)3), aluminum acetylacetonate (Al(acac)3), aluminum maltolate (Al(malt)3) at pH 7.5, or with physiological saline. Two h

Aluminum acetylacetonate was administered to New Zealand white rabbits as liposome preparations and was found to distribute approximately 1:1 between water and phosphatidylcholine dipalmitoyl vesicles. Biochemical monitoring proved that after 2 weeks of daily injection of 40 micrograms of Al(III)

Aluminum is a neurotoxic agent; however, little information has been obtained regarding its molecular cytotoxicity and the effects on the stability of biological membranes. This is mainly due to the ill-defined chemical speciation of the metal compounds. For this reason

The formation of the beta pleated configuration of the amyloid peptide fragment 25-35 in aqueous solution, has been studied using thioflavin-T fluorescence as an indicator of such folding. Both phosphate and adenosine triphosphate (ATP) enhance the formation of aggregated beta-sheets.

Site-selective and narrowed luminescence and excitation spectra in the region of the (2)E <-- (4)A 2 transitions are reported for single crystals of Al(acac) 3/Cr(III) and Al(3-Br-acac) 3/Cr(III) (where acac is acetylacetonate). The R 2 line is pronounced in the
