    Description: Detection of human immunodeficiency virus-type 1 (HIV-1) on only one or a few occasions in infants born to infected mothers has been interpreted to indicate that infection may be transient rather than persistent. Forty-two cases of suspected transient HIV-1 viremia among 1562 perinatally exposed seroreverting infants and one mother were reanalyzed. HIV-1 env sequences were not found in specimens from 20; in specimens from 6, somatic genetic analysis revealed that specimens were mistakenly attributed to an infant; and in specimens from 17, phylogenetic analysis failed to demonstrate the expected linkage between the infant's and the mother's virus. These findings argue that transient HIV-1 infection, if it exists, will only rarely be satisfactorily documented.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Frenkel, L M -- Mullins, J I -- Learn, G H -- Manns-Arcuino, L -- Herring, B L -- Kalish, M L -- Steketee, R W -- Thea, D M -- Nichols, J E -- Liu, S L -- Harmache, A -- He, X -- Muthui, D -- Madan, A -- Hood, L -- Haase, A T -- Zupancic, M -- Staskus, K -- Wolinsky, S -- Krogstad, P -- Zhao, J -- Chen, I -- Koup, R -- Ho, D -- Korber, B -- Apple, R J -- Coombs, R W -- Pahwa, S -- Roberts, N J Jr -- AI27757/AI/NIAID NIH HHS/ -- AI32910/AI/NIAID NIH HHS/ -- UO1-27658/PHS HHS/ -- etc. -- New York, N.Y. -- Science. 1998 May 15;280(5366):1073-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, University of Rochester, Rochester, NY 14642, USA. lfrenkel@u.washington.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9582120" target="_blank"〉PubMed〈/a〉

    Description: Chromosome 2 of Plasmodium falciparum was sequenced; this sequence contains 947,103 base pairs and encodes 210 predicted genes. In comparison with the Saccharomyces cerevisiae genome, chromosome 2 has a lower gene density, introns are more frequent, and proteins are markedly enriched in nonglobular domains. A family of surface proteins, rifins, that may play a role in antigenic variation was identified. The complete sequencing of chromosome 2 has shown that sequencing of the A+T-rich P. falciparum genome is technically feasible.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gardner, M J -- Tettelin, H -- Carucci, D J -- Cummings, L M -- Aravind, L -- Koonin, E V -- Shallom, S -- Mason, T -- Yu, K -- Fujii, C -- Pederson, J -- Shen, K -- Jing, J -- Aston, C -- Lai, Z -- Schwartz, D C -- Pertea, M -- Salzberg, S -- Zhou, L -- Sutton, G G -- Clayton, R -- White, O -- Smith, H O -- Fraser, C M -- Adams, M D -- Venter, J C -- Hoffman, S L -- R01 AI40125-01/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1998 Nov 6;282(5391):1126-32.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Genomic Research, Rockville, MD 20850, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9804551" target="_blank"〉PubMed〈/a〉

    Description: The concentrations of the hydrogen radicals OH and HO2 in the middle and upper troposphere were measured simultaneously with those of NO, O3, CO, H2O, CH4, non-methane hydrocarbons, and with the ultraviolet and visible radiation field. The data allow a direct examination of the processes that produce O3 in this region of the atmosphere. Comparison of the measured concentrations of OH and HO2 with calculations based on their production from water vapor, ozone, and methane demonstrate that these sources are insufficient to explain the observed radical concentrations in the upper troposphere. The photolysis of carbonyl and peroxide compounds transported to this region from the lower troposphere may provide the source of HOx required to sustain the measured abundances of these radical species. The mechanism by which NO affects the production of O3 is also illustrated by the measurements. In the upper tropospheric air masses sampled, the production rate for ozone (determined from the measured concentrations of HO2 and NO) is calculated to be about 1 part per billion by volume each day. This production rate is faster than previously thought and implies that anthropogenic activities that add NO to the upper troposphere, such as biomass burning and aviation, will lead to production of more O3 than expected.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wennberg -- Hanisco -- Jaegle -- Jacob -- Hintsa -- Lanzendorf -- Anderson -- Gao -- Keim -- Donnelly -- Negro -- Fahey -- McKeen -- Salawitch -- Webster -- May -- Herman -- Proffitt -- Margitan -- Atlas -- Schauffler -- Flocke -- McElroy -- Bui -- New York, N.Y. -- Science. 1998 Jan 2;279(5347):49-53.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉P.

    Description: Effects of small population size and reduced genetic variation on the viability of wild animal populations remain controversial. During a 35-year study of a remnant population of greater prairie chickens, population size decreased from 2000 individuals in 1962 to fewer than 50 by 1994. Concurrently, both fitness, as measured by fertility and hatching rates of eggs, and genetic diversity declined significantly. Conservation measures initiated in 1992 with translocations of birds from large, genetically diverse populations restored egg viability. Thus, sufficient genetic resources appear to be critical for maintaining populations of greater prairie chickens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Westemeier -- Brawn -- Simpson -- Esker -- Jansen -- Walk -- Kershner -- Bouzat -- Paige -- New York, N.Y. -- Science. 1998 Nov 27;282(5394):1695-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉R.

    Description: Analysis of the 1,042,519-base pair Chlamydia trachomatis genome revealed unexpected features related to the complex biology of chlamydiae. Although chlamydiae lack many biosynthetic capabilities, they retain functions for performing key steps and interconversions of metabolites obtained from their mammalian host cells. Numerous potential virulence-associated proteins also were characterized. Several eukaryotic chromatin-associated domain proteins were identified, suggesting a eukaryotic-like mechanism for chlamydial nucleoid condensation and decondensation. The phylogenetic mosaic of chlamydial genes, including a large number of genes with phylogenetic origins from eukaryotes, implies a complex evolution for adaptation to obligate intracellular parasitism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stephens, R S -- Kalman, S -- Lammel, C -- Fan, J -- Marathe, R -- Aravind, L -- Mitchell, W -- Olinger, L -- Tatusov, R L -- Zhao, Q -- Koonin, E V -- Davis, R W -- AI 39258/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1998 Oct 23;282(5389):754-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Infectious Diseases, University of California, Berkeley, CA 94720, USA. ctgenome@socrates.berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9784136" target="_blank"〉PubMed〈/a〉

    Description: HOX genes specify cell fate in the anterior-posterior axis of animal embryos. Invertebrate chordates have one HOX cluster, but mammals have four, suggesting that cluster duplication facilitated the evolution of vertebrate body plans. This report shows that zebrafish have seven hox clusters. Phylogenetic analysis and genetic mapping suggest a chromosome doubling event, probably by whole genome duplication, after the divergence of ray-finned and lobe-finned fishes but before the teleost radiation. Thus, teleosts, the most species-rich group of vertebrates, appear to have more copies of these developmental regulatory genes than do mammals, despite less complexity in the anterior-posterior axis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Amores, A -- Force, A -- Yan, Y L -- Joly, L -- Amemiya, C -- Fritz, A -- Ho, R K -- Langeland, J -- Prince, V -- Wang, Y L -- Westerfield, M -- Ekker, M -- Postlethwait, J H -- P01HD22486/HD/NICHD NIH HHS/ -- R01RR10715/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1998 Nov 27;282(5394):1711-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Neuroscience, University of Oregon, Eugene, OR 97403, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9831563" target="_blank"〉PubMed〈/a〉

    Description: The magnetometer and electron reflectometer experiment on the Lunar Prospector spacecraft has obtained maps of lunar crustal magnetic fields and observed the interaction between the solar wind and regions of strong crustal magnetic fields at high selenographic latitude (30 degreesS to 80 degreesS) and low ( approximately 100 kilometers) altitude. Electron reflection maps of the regions antipodal to the Imbrium and Serenitatis impact basins, extending to 80 degreesS latitude, show that crustal magnetic fields fill most of the antipodal zones of those basins. This finding provides further evidence for the hypothesis that basin-forming impacts result in magnetization of the lunar crust at their antipodes. The crustal magnetic fields of the Imbrium antipode region are strong enough to deflect the solar wind and form a miniature (100 to several hundred kilometers across) magnetosphere, magnetosheath, and bow shock system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin -- Mitchell -- Curtis -- Anderson -- Carlson -- McFadden -- Acuna -- Hood -- Binder -- New York, N.Y. -- Science. 1998 Sep 4;281(5382):1480-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉R.

    Description: An angle-resolved photoemission study is reported on Ca2CuO2Cl2, a parent compound of high-Tc superconductors. Analysis of the electron occupation probability, n(k), from the spectra shows a steep drop in spectral intensity across a contour that is close to the Fermi surface predicted by the band calculation. This analysis reveals a Fermi surface remnant, even though Ca2CuO2Cl2 is a Mott insulator. The lowest energy peak exhibits a dispersion with approximately the &cjs3539;coskxa - coskya&cjs3539; form along this remnant Fermi surface. Together with the data from Dy-doped Bi2Sr2CaCu2O8+delta, these results suggest that this d-wave-like dispersion of the insulator is the underlying reason for the pseudo gap in the underdoped regime.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ronning -- Kim -- Feng -- Marshall -- Loeser -- Miller -- Eckstein -- Bozovic I -- Shen -- New York, N.Y. -- Science. 1998 Dec 11;282(5396):2067-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉F.

    Description: Single-nucleotide polymorphisms (SNPs) are the most frequent type of variation in the human genome, and they provide powerful tools for a variety of medical genetic studies. In a large-scale survey for SNPs, 2.3 megabases of human genomic DNA was examined by a combination of gel-based sequencing and high-density variation-detection DNA chips. A total of 3241 candidate SNPs were identified. A genetic map was constructed showing the location of 2227 of these SNPs. Prototype genotyping chips were developed that allow simultaneous genotyping of 500 SNPs. The results provide a characterization of human diversity at the nucleotide level and demonstrate the feasibility of large-scale identification of human SNPs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, D G -- Fan, J B -- Siao, C J -- Berno, A -- Young, P -- Sapolsky, R -- Ghandour, G -- Perkins, N -- Winchester, E -- Spencer, J -- Kruglyak, L -- Stein, L -- Hsie, L -- Topaloglou, T -- Hubbell, E -- Robinson, E -- Mittmann, M -- Morris, M S -- Shen, N -- Kilburn, D -- Rioux, J -- Nusbaum, C -- Rozen, S -- Hudson, T J -- Lipshutz, R -- Chee, M -- Lander, E S -- HG00098/HG/NHGRI NIH HHS/ -- HG01323/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 1998 May 15;280(5366):1077-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, Nine Cambridge Center, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9582121" target="_blank"〉PubMed〈/a〉

    Description: Patients with abetalipoproteinemia, a disease caused by defects in the microsomal triglyceride transfer protein (MTP), do not produce apolipoprotein B-containing lipoproteins. It was hypothesized that small molecule inhibitors of MTP would prevent the assembly and secretion of these atherogenic lipoproteins. To test this hypothesis, two compounds identified in a high-throughput screen for MTP inhibitors were used to direct the synthesis of a highly potent MTP inhibitor. This molecule (compound 9) inhibited the production of lipoprotein particles in rodent models and normalized plasma lipoprotein levels in Watanabe-heritable hyperlipidemic (WHHL) rabbits, which are a model for human homozygous familial hypercholesterolemia. These results suggest that compound 9, or derivatives thereof, has potential applications for the therapeutic lowering of atherogenic lipoprotein levels in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wetterau, J R -- Gregg, R E -- Harrity, T W -- Arbeeny, C -- Cap, M -- Connolly, F -- Chu, C H -- George, R J -- Gordon, D A -- Jamil, H -- Jolibois, K G -- Kunselman, L K -- Lan, S J -- Maccagnan, T J -- Ricci, B -- Yan, M -- Young, D -- Chen, Y -- Fryszman, O M -- Logan, J V -- Musial, C L -- Poss, M A -- Robl, J A -- Simpkins, L M -- Slusarchyk, W A -- Sulsky, R -- Taunk, P -- Magnin, D R -- Tino, J A -- Lawrence, R M -- Dickson, J K Jr -- Biller, S A -- New York, N.Y. -- Science. 1998 Oct 23;282(5389):751-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Metabolic Diseases, Bristol-Myers Squibb Pharmaceutical Research Institute, Princeton, NJ 08543-4000, USA.
