AIDSVAX results: an important open question
(Vaccine, 2003)
Research and clinical data reported during last 10 years indicate the possibility that AIDS vaccines based on the HIV-1 envelope protein gp120 may be worse then useless. A correct assessment of the safety of these AIDS ...
Crystallization behavior of alkoxy-derived cordierite gels
(Journal of Sol-gel Science and Technology, 2003)
Alkoxy-derived cordierite gels were synthesized from tetraethylorthosilicate (TEOS), aluminum isopropoxide (Al(OPri)(3)), and magnesium ethoxide (Mg(OEt)(2)). TEOS was partially hydrolyzed at molar ratios H2O/TEOS=1.2, in ...
Fabrication and characterization of silver-polyvinyl alcohol nanocomposites
(Chemistry of Materials, 2003)
The influence of silver (Ag) nanoparticles on the properties of poly(vinyl alcohol) (PVA) was investigated. The nanocomposite was prepared by mixing a colloidal solution consisting of silver nanoparticles with a water ...
High precision wavelength measurements of QED-sensitive forbidden transitions in highly charged argon ions
(Physical Review Letters, 2003)
We present the results of an experimental study of magnetic dipole (M1) transitions in highly charged argon ions (Ar X, Ar XI, Ar XIV, Ar XV) in the visible spectral range using an electron beam ion trap. Their wavelengths ...
Hydrogen generation from water electrolysis - possibilities of energy saving
(Journal of Power Sources, 2003)
Hydrogen production via electrolysis of water from alkaline aqueous electrolytes is a well-established conventional technology. However, due to high energy requirements of about 4.5-5 kWh/m(n)(3) H-2 in most industrial ...
Application of environmental isotopes in evaluation of pollutants

Effects of age and dexamethasone treatment on glucocorticoid response element and activating protein-1 binding activity in rat brain
(Journals of Gerontology. Series A: Biological Sciences and Medical Sciences, 2003)
The effect of dexamethasone (DEX) on glucocorticoid receptor (GR)-mediated gene expression was examined in the brain of young and aged rats. Electrophoretic mobility shift assays showed that DEX treatment led to an increase ...
