Layered Polyelectrolyte Films as Selective, Ultrathin Barriers for Anion Transport
(2000-06-23)
Synthesis of high-flux composite membranes requires methods for deposition of ultrathin, defect-free films on highly permeable supports. Layer-by-layer deposition of polyelectrolytes on porous alumina (0.02 µm pore diameter) ...
Direct effects of 3,4-methylenedioxymethamphetamine (MDMA) on serotonin or dopamine release and uptake in the caudate putamen, nucleus accumbens, substantia nigra pars reticulate, and the dorsal raphe nucleus slices
(2000-06-15)
We examined the effects of pressure ejected 3,4-methylenedioxymethamphetamine (MDMA) from a micropipette on direct chemically stimulated release, and on electrically stimulated serotonin (5-HT) or dopamine (DA) release in ...
c-abl is involved in the association of p53 and trk A.
(2000-06-15)
The p53 tumour suppressor phosphoprotein associates with proteins involved in DNA replication, transcription, cell cycle machinery and regulation of its own expression. Recently it has been shown that p53 can also bind to ...
Anopheles stephensi Dox-A2 shares common ancestry with genes from distant groups of eukaryotes encoding a 26S proteasome subunit and is in a conserved gene cluster
(2000-06)
The sequence of a cloned Anopheles stephensi gene showed 72% inferred amino acid identity with Drosophila melanogaster Dox-A2 and 93% with its putative ortholog in Anopheles gambiae. Dox-A2 is the reported but herein ...
Nuclear star formation in the hot-spot galaxy HGC 2903
(2000-06)
Circumnuclear regions (CNR) of enhanced star formation (SF) in disk galaxies are usually associated with the presence of stellar bars. Since bars are believed to be one of the most effective mechanisms for transporting ...
Effects of diseases on the growth and yield of spring linseed (Linum usitatissimum), 1988-1998
(2000-06)
In spring linseed field experiments with fungicides at Rothamsted from 1988 to 1998, substantial yield losses associated with diseases occurred in three years and slight losses could be associated with diseases in other ...
Preparation and evaluation of the in vitro drug release properties and mucoadhesion of novel microspheres of hyaluronic acid and chitosan
(2000-05-15)
Rapid mucociliary clearance of intranasally administered drugs is often a key factor in determining the bioavailability of such therapeutic agents. The use of mucoadhesive microparticles provide a potential strategy for ...
Origin of color gradients in elliptical galaxies
(2000-05)
The origin of color gradients in elliptical galaxies is examined by comparing model gradients with those observed in the Hubble Deep Field. The models are constructed so as to reproduce color gradients in local elliptical ...
