The deposition and re-entrainment behaviors of carboxylate-modified latex microspheres (0.2-, 0.5-, 1.0-, and 2.0-microm diameter) were examined in an impinging jet system on both glass and quartz substrata under a variety of environmentally relevant fluid velocities (2.12 x 10(-4) to 1.06 x 10(-3) m sec(-1)) in both the absence and the presence of an energy barrier to deposition. In the absenc...
P2X receptors are a distinct family of ligand-gated ion channels activated by extracellular ATP. Each of the seven identified subunit proteins (P2X1 through P2X7) has been reported to form functional homo-oligomeric channels when expressed in heterologous systems. Functional studies of native receptors, together with patterns of subunit gene expression, suggest that hetero-oligomeric assembly a...
Reducing the transmission loss for below-gap photons is a straightforward way to break the limit of the energy-conversion efficiency of solar cells (SCs). The up-conversion of below-gap photons is very promising for generating additional photocurrent. Here we propose a two-step photon up-conversion SC with a hetero-interface comprising different bandgaps of Al0.3Ga0.7As and GaAs. The below-gap ...
11 G protein gated inward rectifier potassium (GIRK) channels are gated by direct binding of G 12 protein beta-gamma subunits (Gβγ), signaling lipids, and intracellular Na +. In cardiac 13 pacemaker cells, hetero-tetramer GIRK1/4 channels and homo-tetramer GIRK4 channels play 14 a central role in parasympathetic slowing of heart rate. It is known that the Na + binding site of 15 the GIRK1 subun...
In the yeast Saccharomyces cerevisiae there are five nuclear MutS homologs that act in two distinct processes. MSH2, 3, and 6 function in mismatch repair in both vegetative and meiotic cells, whereas MSH4 and MSH5 act specifically to facilitate crossovers between homologs during meiosis. Coimmunoprecipitation as well as two-hybrid experiments indicate that the Msh4 and Msh5 proteins form a hete...
Three aminodi(hetero)arylamines were prepared via a palladium-catalyzed C-N Buchwald-Hartwig coupling of methyl 3-aminothieno[3,2-b]pyridine-2-carboxylate with different bromonitrobenzenes, followed by reduction of the nitro groups of the coupling products to the corresponding amino compounds. The aminodi(hetero)arylamines thus obtained were evaluated for their growth inhibitory effect on four ...
Archaea use glycolytic pathways distinct from those found in bacteria and eukaryotes, where unique enzymes catalyze each reaction step. In this study, we isolated three isozymes of glyceraldehyde oxidoreductase (GAOR1, GAOR2 and GAOR3) from the thermoacidophilic archaeon Sulfolobus tokodaii. GAOR1-3 belong to the xanthine oxidoreductase superfamily, and are composed of a molybdo-pyranopterin su...
Proteins containing the basic-helix-loop-helix (B-HLH) domain have been shown to be important in regulating cellular differentiation. We have isolated a cDNA for a human B-HLH factor, denoted HEB, that shares nearly complete identity in the B-HLH domain with the immunoglobulin enhancer binding proteins encoded by the E2A and ITF2 genes (E proteins). Functional characterization of the protein ex...
OBJECTIVES We investigated vancomycin-intermediate Staphylococcus aureus (VISA) and heterogeneously vancomycin-intermediate S. aureus (hetero-VISA) isolates from clinical specimens of hospitalized patients at Hacettepe University over a 4 year period. METHODS Strains were screened for VISA and hetero-VISA by using brain heart infusion agar containing 4 mg/L vancomycin (BHI-V4) and macro Etest...
