A simple green route has been developed for the synthesis of casein peptide functionalized gold nanoparticles (AuNPs), in which casein peptide acts as a reducing as well as the stabilizing agent. In this report, AuNPs have been characterized on the basis of spectroscopic and microscopic results; which showed selective and sensitive response toward Al3+ in aqueous media, and Al3+ induces aggrega...

The influences of eight metal ions (i.e., Na+, Ca2+, Ag+, Co2+, Cu2+, Al3+, Zn2+, and Mn4+) on mycelia growth and palmarumycins C(12) and C(13) production in liquid culture of the endophytic fungus Berkleasmium sp. Dzf12 were investigated. Three metal ions, Ca2+, Cu2+ and Al3+ were exhibited as the most effective to enhance mycelia growth and palmarumycin production. When calcium ion (Ca2+) was...

2 Institute for Biomedical Research, Kaunas University of Medicine, Eivenių 4, LT-50009 Kaunas, Lithuania The object of the study was to evaluate the effect of aluminum ions (Al3+) on activity of tRNALeu and leucyl-tRNA synthetase from mouse liver in vivo and in vitro. Experiments were done on white laboratory mice using intraperitoneal injections of 0.5 LD50 AlCl3 solution (25 mg Al 3+/kg body...

The herpes simplex virus type 1 (HSV-1) latency-associated transcript (LAT) is abundantly expressed in latently infected sensory neurons. In small animal models of infection, expression of the first 1.5 kb of LAT coding sequences is necessary and sufficient for wild-type reactivation from latency. The ability of LAT to inhibit apoptosis is important for reactivation from latency. Within the fir...

A recent proposal (Clin Chem 1992;38:1809-18) that inorganic phosphate is the predominant small molecule binding Al3+ in blood serum is shown to be incorrect. Experiments in which Al3+ is added to solutions containing phosphate and citrate in the same proportions as in serum clearly show that citrate prevents formation of any aluminum phosphate precipitate, and analysis of these data indicates ...

Aluminum (Al) toxicity is the primary factor limiting crop growth in acidic soils. Boron (B) alleviates Al toxicity in plants, which is mainly considered to be due to the formation of Rhamnogalacturonan II-B (RGII-B) complexes, which helps to stabilize the cytoskeleton. It is unclear yet whether this is due to the increasing of net negative charges and/or further mechanisms. Kinetics of Al accu...

Formation of Al3Zr or Al3(Zr1 x Tix) precipitates with a metastable L12 structure was investigated in conventionally solidified A1–0.1 Zr, Al–0.2 Zr, Al–0.1 Zr–0.1 Ti, and Al–0.2 Zr–0.2 Ti (at.%) alloys aged isothermally at 375, 400, or 425 C. Pronounced hardening results from nanometer-scale, spheroidal Al3Zr or Al3(Zr1 xTix) (L12) precipitates within solute-enriched dendrites. Interdendritic ...

The capacity of Al3+ to promote oxidative damage to brain membranes was investigated both in vitro and in vivo. In vitro, Al3+ and related metals (Sc3+, Ga3+, In3+, Be2+, Y3+, and La3+) stimulated Fe2+-initiated lipid and protein oxidation in brain myelin and synaptic membranes. Al3+, Sc3+, Y3+, and La3+ significantly promoted protein-associated carbonyl production in myelin, while in synaptic ...

The microstructure of ternary L12-Al3(Sc1 yREy) intermetallics, where RE is one of the rare-earth elements selected from five light (La, Ce, Nd, Sm or Eu) or two heavy lanthanoids (Yb or Lu), was investigated as a function of RE concentration for 0.02 y 0.75. Alloys with light RE show two phases: L12-Al3(Sc,RE) and D019-Al3(RE,Sc) (or C11b-Al4(Eu,Sc)). Alloys with heavy RE exhibit a single L12A...
