Incubation of purified recombinant human tau protein with aluminum salts at concentrations > or = 100 microM induces aggregation of tau that prevents its entry into SDS-polyacrylamide gels and filtration through nylon membranes. This effect is noncovalent and can be reversed by addition of EDTA. However, when incubated along with ATP, GTP, or CTP, aluminum catalyzes a covalent linkage that resu...
Ricin is a potent toxin associated with bioterrorism for which no vaccine or specific countermeasures are currently available. A stable, non-toxic and immunogenic recombinant ricin A-chain vaccine (RTA 1-33/44-198) has been developed by protein engineering. We identified optimal formulation conditions for this vaccine under which it remained stable and potent in storage for up to 18 months, and...
Bauxite residue is a high-iron waste of the alumina industry with significant contents scandium, aluminum, and titanium. This study focuses on recovery Sc, Al, Ti, Si from iron-depleted bauxite (IDBR) into valuable products. Iron depletion was carried out using reduction roasting followed by low-intensity magnetic separation to enrich in Sc reduce an adverse effect iron scandium extraction. Hyd...
Effective protection of power sources from corrosion is critical in the development of abiotic fuel cells, biofuel cells, hybrid cells and biobateries for implantable bioelectronics. Corrosion of these bioelectronic devices result in device inability to generate bioelectricity. In this paper Al/Au/ZnO was considered as a possible anodic substrate for the development of a hybrid cell. The protec...

This method was developed for the determination of trace amounts of aluminum(III) in dialysis concentrates using atomic absorption spectrometry after coprecipitation with lanthanum phosfate. The analytical parameters that influenced the quantitave coprecipitation of analyte including amount of lanthanum, amount of phosfate, pH and duration time were optimized. The % recoveries of the analyte io...
BACKGROUND High fibroblast growth factor-23 (FGF-23) levels are associated with adverse outcomes. We studied the responsiveness of FGF-23 and mineral metabolism to altered dietary phosphate intake in chronic kidney disease (CKD) and healthy control patients. METHODS Thirty patients were enrolled: 18 normophosphatemic CKD subjects and 12 healthy controls. The study duration was 21 days with th...
An approach involving the preparation of biodegradable microparticles with a cationic surface was developed to improve the delivery of adsorbed DNA into antigen-presenting cells after i.m. injection. The microparticles released intact and functional DNA over 2 weeks in vitro. In addition, the microparticles induced higher levels of marker gene expression in vivo. After i.m. immunization, the mi...
Selective solid-phase reduction of iron and phosphorus in oolite ores the Lisakovsky Ayat deposits was experimentally studied. Using X-ray phase analysis, composition initial samples after roasting determined. Goethite, magnetite quartz were found both deposits. Phosphorus ore deposit is form aluminum phosphate hydrophosphate, – as a component calcium hydrophosphate. Experiments on carried out ...
