A long pathlength, Fourier transform spectrum of pure water vapour [J. Mol. Spectrosc. 211 (2002) 169] has been fitted and analysed. Line centres, intensities, and self-broadening parameters have been obtained for about 3900 lines with intensities less then 1 · 10 24 cm/molecule. Transitions to 240 newly observed energy levels of H2O have been identified. 855 lines have been assigned to three o...
Positive allosteric modulators (PAMs) of metabotropic glutamate receptor subtype 5 (mGlu(5)) have emerged as an exciting new approach for the treatment of schizophrenia and other central nervous system (CNS) disorders. Of interest, some mGlu(5) PAMs act as pure PAMs, only potentiating mGlu(5) responses to glutamate whereas others [allosteric agonists coupled with PAM activity (ago-PAMs)] potent...
Theoretical work predicts that the strong dependence of Tc on pure shear strain within the a-b plane of optimally doped YBa2Cu3O7−δ results in heterogenous columnar pins of vortex lines about dislocation lines and about nano-columns inclusions aligned in parallel to the c axis. The critical current of a rigid vortex lattice driven by the Lorentz force in the presence of such clusters of pin/ant...
Methionine dependency has been reported in cancer cell lines and primary tumors. Thus, L-methionine deprivation might have potential value for the treatment of human cancers with a methionine requirement. L-Methionine-a-deamino-'y-mercaptomethane-lyase has been reported to decrease plasma methionine levels and to inhibit tumor growth in exper imental animals but has not been studied extensively...
in order to determine combining ability, heritability and heterosis of some agronomic traits in rice, 4 pure lines were crossed with 2 cytoplasmic male sterile testers. parents and their f1 progenies arranged in rcb design with three replications. analysis of variance showed significant differences among genotypes for all traits, except for filled grains/panicle. furthermore, the crosses effect...
dendrostellera lessertii (thymelaeaceae) is a toxic plant that grows in parts of iran. the anti-proliferative properties of its crude methanol extract and one of its active components, 3-hydrogenkwadaphnin (3-hk), have been established using several cancer cell lines. methods: in a further attempt to determine the mode of action, two groups of synchronously growing cells were treated with a sin...
We present an analysis of 40 cool helium-rich white dwarfs found in the Hamburg/ESO survey. They were selected for follow-up spectroscopy because of their U −B colour below -0.18, the absence of strong absorption lines, and a continuum shape similar to that of a quasar. Effective temperatures for individual stars were determined by fitting model atmospheres of nearly pure helium with a small ad...
