    Description: Activated epidermal growth factor (EGF) receptors induce the formation of various complexes of intracellular signaling proteins that are mediated by SRC homology 2 (SH2) and SH3 domains. The activated receptors are also rapidly internalized into the endocytotic compartment and degraded in lysosomes. EGF stimulation of canine epithelial cells induced a rapid and transient association of the SH3-SH2-SH3 protein GRB2 with dynamin, a guanosine triphosphatase that regulates endocytosis. Disruption of GRB2 interactions by microinjection of a peptide corresponding to the GRB2 SH2 domain or its phosphopeptide ligand blocked EGF receptor endocytosis; other SH2 domains that bind EGF receptors or antibodies that neutralize RAS did not. Both activation and termination of EGF signaling appear to be regulated by the diverse interactions of GRB2.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Z -- Moran, M F -- New York, N.Y. -- Science. 1996 Jun 28;272(5270):1935-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Banting and Best Department of Medical Research, University of Toronto, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8658166" target="_blank"〉PubMed〈/a〉

    Description: CHOP, a member of the C/EBP family of transcription factors, mediates effects of cellular stress on growth and differentiation. It accumulates under conditions of stress and undergoes inducible phosphorylation on two adjacent serine residues (78 and 81). In vitro, CHOP is phosphorylated on these residues by p38 mitogen-activated protein kinase (MAP kinase). A specific inhibitor of p38 MAP kinase, SB203580, abolished the stress-inducible in vivo phosphorylation of CHOP. Phosphorylation of CHOP on these residues enhanced its ability to function as a transcriptional activator and was also required for the full inhibitory effect of CHOP on adipose cell differentiation. CHOP thus serves as a link between a specific stress-activated protein kinase, p38, and cellular growth and differentiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, X Z -- Ron, D -- New York, N.Y. -- Science. 1996 May 31;272(5266):1347-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Skirball Institute of Biomolecular Medicine, New York University Medical Center, 10016, NY, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8650547" target="_blank"〉PubMed〈/a〉

    Description: In recent years, improvements in the sensitivity of nuclear magnetic resonance have made it possible to detect progressively smaller numbers of nuclei. Experiments and studies previously thought to be impractical can now be undertaken, for example, the study of phenomena at surfaces. Nuclear magnetic resonance has been applied to study simple molecules (carbon monoxide, acetylene, and ethylene) adsorbed on metal surfaces (ruthenium, rhodium, palladium, osmium, iridium, and platinum). The metals, in the form of clusters 10 to 50 angstroms in diameter, supported on alumina, are typical of real catalysts. The experiments provide information about the bonding of the molecules to the metal, the structures the molecules assume after adsorption, the motion of molecules on the surface, the breakup of molecules induced by heating, and the products of such breakup.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, P K -- Ansermet, J P -- Rudaz, S L -- Wang, Z -- Shore, S -- Slichter, C P -- Sinfelt, J H -- New York, N.Y. -- Science. 1986 Oct 3;234(4772):35-41.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17742632" target="_blank"〉PubMed〈/a〉

    Notes: Nascent CD3 radicals produced by photodissociation of CD3I after absorption of 266 nm radiation by the A˜ state are studied using the photofragment imaging technique. Two-photon, resonance-enhanced, multiphoton ionization [(2+1) REMPI] probes CD3 via the 3pz 2A'2 Rydberg excited electronic state. CD3I photodissociation at 266 nm is found to produce ground-electronic-state CD3 radicals with substantial vibrational excitation of the ν2 umbrella mode. Rotational constants are determined for v=0, 1, and 2 of ν2 in the 3pz excited state by analysis of the spectra. A first-order perturbation and diagonalization procedure is used to generate potential energy curves for the umbrella mode in both the ground and excited electronic states and Franck–Condon factors for various transitions between the states. These results should prove useful when employing REMPI to characterize methyl radicals in many environments.

    Notes: The correlation function presented by Debye et al. for characterizing the random two-phase structure in solids is further extended by considering an effect of partial ordering to describe the statistical features in phase separation structures of polymer blends. The new correlation function is in the form γ(r)=exp(−r/a0 )cos(q0 r) with two parameters. The scattering intensity distribution calculated from this function can predict a maximum whose sharpness and position are characterized by a0 and q0 . Good agreement was achieved between the calculated intensity and measured small-angle light scattering curve from phase-separated poly(methyl methacrylate)/poly(vinyl acetate) blends.

    Notes: We investigate, by numerical simulation, the shear layer instability associated with the outer layer of a spiral vortex formed behind an impulsively started thin ellipse. The unstable free shear layer undergoes a secondary instability. We connect this instability with the dynamics of corner vortices adjacent to the tip of the ellipse by observing that the typical turnover time of the corner vortex matches the period of the unstable mode in the shear layer. We suggest that the corner vortex acts as a signal generator, and produces periodic perturbation which triggers the instability. © 1999 American Institute of Physics.

    Notes: The room temperature Raman spectra of the hexagonal GaN epilayer grown on [111]- oriented MgAl2O4 substrate were measured in various backscattering and right angle scattering geometries. All of the symmetry—allowed optical phonon modes were observed except the E2 (low frequency) mode. The quasitransverse and quasilongitudinal modes were also observed in the x(zx)z and x(yy)z configurations, which are the mixed modes of pure transverse and longitudinal modes with A1 and E1 symmetry, respectively. © 1999 American Institute of Physics.
