    A physical map of 30,000 human genes (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-10-23
    Description: A map of 30,181 human gene-based markers was assembled and integrated with the current genetic map by radiation hybrid mapping. The new gene map contains nearly twice as many genes as the previous release, includes most genes that encode proteins of known function, and is twofold to threefold more accurate than the previous version. A redesigned, more informative and functional World Wide Web site (www.ncbi.nlm.nih.gov/genemap) provides the mapping information and associated data and annotations. This resource constitutes an important infrastructure and tool for the study of complex genetic traits, the positional cloning of disease genes, the cross-referencing of mammalian genomes, and validated human transcribed sequences for large-scale studies of gene expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deloukas, P -- Schuler, G D -- Gyapay, G -- Beasley, E M -- Soderlund, C -- Rodriguez-Tome, P -- Hui, L -- Matise, T C -- McKusick, K B -- Beckmann, J S -- Bentolila, S -- Bihoreau, M -- Birren, B B -- Browne, J -- Butler, A -- Castle, A B -- Chiannilkulchai, N -- Clee, C -- Day, P J -- Dehejia, A -- Dibling, T -- Drouot, N -- Duprat, S -- Fizames, C -- Fox, S -- Gelling, S -- Green, L -- Harrison, P -- Hocking, R -- Holloway, E -- Hunt, S -- Keil, S -- Lijnzaad, P -- Louis-Dit-Sully, C -- Ma, J -- Mendis, A -- Miller, J -- Morissette, J -- Muselet, D -- Nusbaum, H C -- Peck, A -- Rozen, S -- Simon, D -- Slonim, D K -- Staples, R -- Stein, L D -- Stewart, E A -- Suchard, M A -- Thangarajah, T -- Vega-Czarny, N -- Webber, C -- Wu, X -- Hudson, J -- Auffray, C -- Nomura, N -- Sikela, J M -- Polymeropoulos, M H -- James, M R -- Lander, E S -- Hudson, T J -- Myers, R M -- Cox, D R -- Weissenbach, J -- Boguski, M S -- Bentley, D R -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1998 Oct 23;282(5389):744-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Sanger Centre, Hinxton Hall, Hinxton, Cambridge CB10 1SA UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9784132" target="_blank"〉PubMed〈/a〉

    Notes: Surface roughness has been shown to affect differentiation and local factor production of MG63 osteoblast-like cells. This study examined whether surface roughness alters cellular response to circulating hormones such as 1α,25-(OH)2D3. Unalloyed titanium (Ti) disks were pretreated with HF/HNO3 (PT) and then were machined and acid-etched (MA). Ti disks also were sandblasted (SB), sandblasted and acid etched (CA), or plasma sprayed with Ti particles (PS). The surfaces, from smoothest to roughest, were: PT, MA, CA, SB, and PS. MG63 cells were cultured to confluence on standard tissue culture polystyrene (plastic) or the Ti surfaces and then treated for 24 h with either 10-8M or 10-7M 1α,25-(OH)2D3 or vehicle (control). Cellular response was measured by assaying cell number, cell layer alkaline phosphatase specific-activity, and the production of osteocalcin, latent (L) TGFβ, and PGE2. Alkaline phosphatase activity was affected by surface roughness; as the surface became rougher, the cells showed a significant increase in alkaline phosphatase activity. Addition of 1α,25-(OH)2D3 to the cultures caused a dose-dependent stimulation of alkaline phosphatase activity that was synergistic with the effect caused by surface roughness alone. 1α,25-(OH)2D3 also caused a synergistic increase in osteocalcin production as well as local factor (LTGFβ and PGE2) production on the rougher CA, SB, and PS surfaces, but it had no effect on the production on smooth surfaces. The inhibitory effect of surface roughness on cell number was not affected by 1α,25-(OH)2D3 except on the SB surface. 1α,25-(OH)2D3 decreased cell number, increased alkaline phosphatase activity and osteocalcin production, and had no effect on LTGFβ or PGE2 production by MG63 cells grown on tissue culture polystyrene. These data suggest that bone cell response to systemic hormones is modified by surface roughness and that surface roughness increases the responsiveness of MG63 cells to 1α,25-(OH)2D3. They also suggest that the endocrine system is actively involved in normal bone healing around implants. © 1998 John Wiley & Sons, Inc. J Biomed Mater Res, 39, 77-85, 1998.

    Prostaglandins mediate the effects of titanium surface roughness on MG63 osteoblast-like cells and alter cell responsiveness to 1α,25-(OH)2D3 (1998)

    Notes: Surface roughness affects proliferation, differentiation (alkaline phosphatase and osteocalcin), local factor production [transforming growth factor (TGFβ) and prostaglandin E2 (PGE2)], and response to 1,25-(OH)2D3 (1,25) of MG63 osteoblast-like cells. In this study, we examined whether the effect of surface roughness on MG63 cells is mediated by prostaglandins produced by the cells. Unalloyed titanium (Ti) disks were pretreated with HF/HNO3 (PT) and then machined and acid-etched (MA). Disks were also coarse grit-sandblasted (SB), coarse grit-sandblasted and acid-etched (CA), or plasma-sprayed with Ti particles (PS). The surfaces, from smoothest to roughest, were PT, MA, CA, SB, and PS. MG63 cells were cultured to confluence on the Ti disks in the presence or absence of 10-7M indomethacin (Indo), a specific inhibitor of cyclooxygenase activity, resulting in decreased prostaglandin production. When the cells reached confluence, cell number, cell layer alkaline phosphatase specific activity (ALPase), and osteocalcin (OC) and latent TGFβ (LTGFβ) production were determined. In addition, confluent cultures which had been grown in the absence of Indo were exposed to 10-7M 1,25, 10-7M Indo, or a combination of the two for 24 h. On the rougher surfaces, cell number was decreased and ALPase, OC, and LTGFβ were increased. When indomethacin was present throughout the culture period, the effect of surface roughness on cell number, OC, and LTGFβ was abolished. ALPase was reduced, but surface roughness-dependent effects were still observed. Addition of indomethacin to confluent cultures for 24 h had no effect on any of the parameters examined, with one exception: Cells cultured on MA surfaces exhibited a more differentiated phenotype. 1,25 increased all parameters examined on SB, CA, and PS surfaces. When indomethacin was added with 1,25, the 1,25-dependent effects on cell number and OC and LTGFβ production were abolished; however, ALPase was unaffected. This indicates that bone cell response to systemic hormones may be modified by implant surface roughness. This effect may be mediated, at least in part, by prostaglandins produced by the same cells. © 1998 John Wiley & Sons, Inc. J Biomed Mater Res, 41, 489-496, 1998.

    Requirement for IL-13 independently of IL-4 in experimental asthma (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-12-18
    Description: The pathogenesis of asthma reflects, in part, the activity of T cell cytokines. Murine models support participation of interleukin-4 (IL-4) and the IL-4 receptor in asthma. Selective neutralization of IL-13, a cytokine related to IL-4 that also binds to the alpha chain of the IL-4 receptor, ameliorated the asthma phenotype, including airway hyperresponsiveness, eosinophil recruitment, and mucus overproduction. Administration of either IL-13 or IL-4 conferred an asthma-like phenotype to nonimmunized T cell-deficient mice by an IL-4 receptor alpha chain-dependent pathway. This pathway may underlie the genetic associations of asthma with both the human 5q31 locus and the IL-4 receptor.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3897229/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3897229/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grunig, G -- Warnock, M -- Wakil, A E -- Venkayya, R -- Brombacher, F -- Rennick, D M -- Sheppard, D -- Mohrs, M -- Donaldson, D D -- Locksley, R M -- Corry, D B -- 03344/PHS HHS/ -- 47412/PHS HHS/ -- K08 HL003344/HL/NHLBI NIH HHS/ -- T32 HL07185/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1998 Dec 18;282(5397):2261-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, San Francisco General Hospital, University of California San Francisco, San Francisco, CA 94143, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9856950" target="_blank"〉PubMed〈/a〉

    Notes: Metabolism is the conversion of available energy sources to those energy forms required for sustaining and propagating living organisms; this is simply biological energy conversion. Proteins are the machines of metabolism; they are the engines of motility and the other machines that interconvert energy forms not involving motion. Accordingly, metabolic engineering becomes the use of natural protein-based machines for the good of society. In addition, metabolic engineering can utilize the principles, whereby proteins function, to design new protein-based machines to fulfill roles for society that proteins have never been called upon throughout evolution to fulfill.This article presents arguments for a universal mechanism whereby proteins perform their diverse energy conversions; it begins with background information, and then asserts a set of five axioms for protein folding, assembly, and function and for protein engineering. The key process is the hydrophobic folding and assembly transition exhibited by properly balanced amphiphilic protein sequences. The fundamental molecular process is the competition for hydration between hydrophobic and polar, e.g., charged, residues. This competition determines Tt, the onset temperature for the hydrophobic folding and assembly transition, Nhh, the numbers of waters of hydrophobic hydration, and the pKa of ionizable functions.Reported acid-base titrations and pH dependence of microwave dielectric relaxation data simultaneously demonstrate the interdependence of Tt, Nhh and the pKa using a series of microbially prepared protein-based poly(30mers) with one glutamic acid residue per 30mer and with an increasing number of more hydrophobic phenylalanine residues replacing valine residues. Also, reduction of nicotinamides and flavins is shown to lower Tt, i.e., to increase hydrophobicity.Furthermore, the argument is presented, and related to an extended Henderson-Hasselbalch equation, wherein reduction of nicotinamides represents an increase in hydrophobicity and resulting hydrophobic-induced pKa shifts become the basis for understanding a primary energy conversion (proton transport) process of mitochondria. © 1998 John Wiley & Sons, Inc.

    Notes: The Membrane Bioreactor for Biotransformations (MBB) is based on the aqueous/organic two-phase system, and uses a tubular silicone rubber membrane to separate the two liquid phases. This avoids the key problem associated with direct contact two-phase processes, specifically, product emulsification. The baker's yeast mediated reduction of geraniol to citronellol was used as a model biotransformation to demonstrate MBB operation. Values for the overall mass transfer coefficient were determined for geraniol, (2.0 × 10-5 ms-1), and for citronellol, (2.1 × 10-5 ms-1) diffusion across the silicone rubber membrane. Using these values, and the specific activity of the biocatalyst (5 nmols-1g biomass-1), a suitable membrane surface area: biomass ratio was determined as 2.4 × 10-3 m2g biomass-1. The bioreactor was operated at this surface area: biomass ratio and achieved a product accumulation rate 90-95% that of a conventional direct contact two-phase system. The slight reduction in product accumulation rate was shown not to be due to mass transfer limitations with respect to reactant delivery or product extraction. © 1998 John Wiley & Sons, Inc.

    Notes: The W/TiN/Ti/Si contact structures needed for ultra-large-scale integrated circuits have been studied using cross-sectional transmission electron microscopy (TEM) and multi-spectral Auger electron microscopy. Access to the Ti/Si interface for chemical characterization using SEM, Auger and electron energy-loss imaging and spectroscopy has been achieved by using a novel method of bevelled polishing of the silicon substrate material. Cross-sectional TEM was used to calibrate the depth scale in the MULSAM image sets, so allowing measurements of the thicknesses of various interfacial layers and the penetration of the ohmic contacts into the silicon. The TiN layer, providing adhesion of the tungsten as well as acting as a diffusion barrier, appears to have a domed shape, which penetrates the tungsten overlayer to a greater extent in the contact centres. The results of this work, combined with earlier, related, studies, enable a three-dimensional characterization of the bottom and sidewall structures in these contacts. © 1998 John Wiley & Sons, Ltd.

    Mutation of a gene encoding a protein with extracellular matrix motifs in Usher syndrome type IIa (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-06-20
    Description: Usher syndrome type IIa (OMIM 276901), an autosomal recessive disorder characterized by moderate to severe sensorineural hearing loss and progressive retinitis pigmentosa, maps to the long arm of human chromosome 1q41 between markers AFM268ZD1 and AFM144XF2. Three biologically important mutations in Usher syndrome type IIa patients were identified in a gene (USH2A) isolated from this critical region. The USH2A gene encodes a protein with a predicted size of 171.5 kilodaltons that has laminin epidermal growth factor and fibronectin type III motifs; these motifs are most commonly observed in proteins comprising components of the basal lamina and extracellular matrixes and in cell adhesion molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eudy, J D -- Weston, M D -- Yao, S -- Hoover, D M -- Rehm, H L -- Ma-Edmonds, M -- Yan, D -- Ahmad, I -- Cheng, J J -- Ayuso, C -- Cremers, C -- Davenport, S -- Moller, C -- Talmadge, C B -- Beisel, K W -- Tamayo, M -- Morton, C C -- Swaroop, A -- Kimberling, W J -- Sumegi, J -- 5PO1 DC01813-05/DC/NIDCD NIH HHS/ -- DC03402/DC/NIDCD NIH HHS/ -- EY07003/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1998 Jun 12;280(5370):1753-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology and Microbiology, University of Nebraska Medical Center, Omaha, NE 68198, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9624053" target="_blank"〉PubMed〈/a〉

    DARPP-32: regulator of the efficacy of dopaminergic neurotransmission (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-08-07
    Description: Dopaminergic neurons exert a major modulatory effect on the forebrain. Dopamine and adenosine 3',5'-monophosphate-regulated phosphoprotein (32 kilodaltons) (DARPP-32), which is enriched in all neurons that receive a dopaminergic input, is converted in response to dopamine into a potent protein phosphatase inhibitor. Mice generated to contain a targeted disruption of the DARPP-32 gene showed profound deficits in their molecular, electrophysiological, and behavioral responses to dopamine, drugs of abuse, and antipsychotic medication. The results show that DARPP-32 plays a central role in regulating the efficacy of dopaminergic neurotransmission.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fienberg, A A -- Hiroi, N -- Mermelstein, P G -- Song, W -- Snyder, G L -- Nishi, A -- Cheramy, A -- O'Callaghan, J P -- Miller, D B -- Cole, D G -- Corbett, R -- Haile, C N -- Cooper, D C -- Onn, S P -- Grace, A A -- Ouimet, C C -- White, F J -- Hyman, S E -- Surmeier, D J -- Girault, J -- Nestler, E J -- Greengard, P -- DA 08227/DA/NIDA NIH HHS/ -- DA10044/DA/NIDA NIH HHS/ -- F31 DA005794/DA/NIDA NIH HHS/ -- MH40899/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1998 Aug 7;281(5378):838-42.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular and Cellular Neuroscience, The Rockefeller University, New York, NY 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9694658" target="_blank"〉PubMed〈/a〉

    Intercomparison of Pulsed Lidar Data with Flight Level CW Lidar Data and Modeled Backscatter from Measured Aerosol Microphysics Near Japan and Hawaii (1998)
    In:  CASI
    Details
    Publication Date: 2019-08-15
    Description: Aerosol backscatter coefficient data were examined from two nights near Japan and Hawaii undertaken during NASA's Global Backscatter Experiment (GLOBE) in May-June 1990. During each of these two nights the aircraft traversed different altitudes within a region of the atmosphere defined by the same set of latitude and longitude coordinates. This provided an ideal opportunity to allow flight level focused continuous wave (CW) lidar backscatter measured at 9.11-micron wavelength and modeled aerosol backscatter from two aerosol optical counters to be compared with pulsed lidar aerosol backscatter data at 1.06- and 9.25-micron wavelengths. The best agreement between all sensors was found in the altitude region below 7 km, where backscatter values were moderately high at all three wavelengths. Above this altitude the pulsed lidar backscatter data at 1.06- and 9.25-micron wavelengths were higher than the flight level data obtained from the CW lidar or derived from the optical counters, suggesting sample volume effects were responsible for this. Aerosol microphysics analysis of data near Japan revealed a strong sea-salt aerosol plume extending upward from the marine boundary layer. On the basis of sample volume differences, it was found that large particles were of different composition compared with the small particles for low backscatter conditions.
