    Defective lymphotoxin-beta receptor-induced NF-kappaB transcriptional activity in NIK-deficient mice (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-03-17
    Description: The role of NF-kappaB-inducing kinase (NIK) in cytokine signaling remains controversial. To identify the physiologic functions of NIK, we disrupted the NIK locus by gene targeting. Although NIK-/- mice displayed abnormalities in both lymphoid tissue development and antibody responses, NIK-/- cells manifested normal NF-kappaB DNA binding activity when treated with a variety of cytokines, including tumor necrosis factor (TNF), interleukin-1 (IL-1), and lymphotoxin-beta (LTbeta). However, NIK was selectively required for gene transcription induced through ligation of LTbeta receptor but not TNF receptors. These results reveal that NIK regulates the transcriptional activity of NF-kappaB in a receptor-restricted manner.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yin, L -- Wu, L -- Wesche, H -- Arthur, C D -- White, J M -- Goeddel, D V -- Schreiber, R D -- New York, N.Y. -- Science. 2001 Mar 16;291(5511):2162-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Immunology, Department of Pathology and Immunology, Washington University School of Medicine, St. Louis, MO 63110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11251123" target="_blank"〉PubMed〈/a〉

    Notes: In this article, we present low-pressure steady-state results for carbon monoxide oxidation over Rh(100). The results are comparable to those found for other Group VIII transition metals. For a fixed oxygen pressure, the reaction rate is first order in CO pressure until a critical pressure is reached, above which the reaction rate sharply diminishes and the order becomes negative in CO pressure. Coverages of carbon monoxide under steady-state working conditions have been measured.

    Titration of oxygen chemisorbed on platinum: Experiment and simulation (1980)

    Notes: The titration of chemisorbed oxygen by carbon monoxide to form carbon dioxide has been studied from 373 to 673 K over polycrystalline platinum. The pressure transients for CO and CO2 have been measured and simulated numerically. A complex Langmuir-Hinshelwood mechanism is found which fits all the data, and it is not necessary to invoke Eley-Rideal kinetics. The results fall into two temperature regimes, above and below 473 K, which are characterized by different Arrhenius parameters. A change in activation energy with oxygen coverage is also found below 473 K.

    A comparison of two-dimensional and three-dimensional trajectory calculations in thermal HBr2 and H2Br systems (1975)

    Notes: Two-dimensional (2D) and three-dimensional (3D) quasiclassical trajectory calculations on H + Br2 at 300°K and H + HBr at 1000°K are reported. Angular scattering, energy disposal, and impact parameter distributions for reactive collisions are compared after removal of phase-space factors (dimensionality bias) as a means of examining the similarities and differences in the dynamic bias in 2D and 3D. Qualitatively, for all reactive processes studied, the 3D trajectory calculated distributions are reproduced by the phase-space adjusted 2D trajectory data. Thus the surprisal of these angular scattering, energy disposal, and impact parameter distributions is dimensionally invariant, and the same dynamic bias appears in 2D and 3D. A systematic method for converting 2D reaction probabilities and maximum reactive impact parameters into 3D rate coefficients is presented. We find that trajectory calculated 3D rate coefficients may in general differ markedly from those derived from 2D trajectory data. In particular, the surprisal associated with rate coefficients depends on dimensionality for the H + HBr → H2 + Br reaction, but is invariant for the H′ + HBr → H′Br + Br and H + Br2 → HBr + Br reactions.
