This article provides the complete description of results from the Phase I data set of the Sudbury Neutrino Observatory (SNO). The Phase I data set is based on a 0.65 kiloton-year exposure of 2H2O (in the following denoted as D2O) to the solar B8 neutrino flux. Included here are details of the SNO physics and detector model, evaluations of systematic uncertainties, and estimates of backgrounds. Also discussed are SNO's approach to statistical extraction of the signals from the three neutrino reactions (charged current, neutral current, and elastic scattering) and the results of a search for a day-night asymmetry in the …

Formation Of Tellurium Nanocrystals During Anaerobic Growth Of Bacteria That Use Te Oxyanions As Respiratory Electron Acceptors, Shaun M. Baesman, Thomas D. Bullen, James Dewald, Donghui Zhang, Seamus Curran, Farhana S. Islam, Terry J. Beveridge, Ronald S. Oremland

Faculty Publications

Certain toxic elements support the metabolism of diverse prokaryotes by serving as respiratory electron acceptors for growth. Here, we demonstrate that two anaerobes previously shown to be capable of respiring oxyanions of selenium also achieve growth by reduction of either tellurate [Te(VI)] or tellurite [Te(IV)] to elemental tellurium [Te(0)]. This reduction achieves a sizeable stable-Te-isotopic fractionation (isotopic enrichment factor [ε] = -0.4 to -1.0 per ml per atomic mass unit) and results in the formation of unique crystalline Te(0) nanoarchitectures as end products. The Te(0) crystals occur internally within but mainly externally from the cells, and each microorganism forms a …

Induction Of Host Chemotactic Response By Encephalitozoon Spp., Jeffrey Fischer, Jeffrey West, Nnenaya Agochukwu, Colby Suire, Hollie Hale-Donze

Faculty Publications

Microsporidians are a group of emerging pathogens typically associated with chronic diarrhea in immunocompromised individuals. The number of reports of infections with these organisms and the disseminated pathology is growing as diagnostic tools become more readily available. However, little is known about the innate immune response induced by and generated against these parasites. Using a coculture chemotaxis system, primary human macrophages were infected with Encephalitozoon cuniculi or Encephalitozoon intestinalis, and the recruitment of naïve monocytes was monitored. Encephalitozoon spp. induced an average threefold increase in migration of naïve cells 48 h postinfection, which corresponded to optimal infection of monocyte-derived- macrophages. …

A Sine-Based Dichotomous Key For Primate Identification, Scott W. Herke, Jinchuan Xing, David A. Ray, Jacquelyn W. Zimmerman, Richard Cordaux, Mark A. Batzer

Faculty Publications

For DNA samples or 'divorced' tissues, identifying the organism from which they were taken generally requires some type of analytical method. The ideal approach would be robust even in the hands of a novice, requiring minimal equipment, time, and effort. Genotyping SINEs (Short INterspersed Elements) is such an approach as it requires only PCR-related equipment, and the analysis consists solely of interpreting fragment sizes in agarose gels. Modern primate genomes are known to contain lineage-specific insertions of Alu elements (a primate-specific SINE); thus, to demonstrate the utility of this approach, we used members of the Alu family to identify DNA …

Nmr Structural Characterization Of Substrates Bound To N-Acetylglucosaminyltransferase V, Megan A. Macnaughtan, Maria Kamar, Gerardo Alvarez-Manilla, Andre Venot, John Glushka, J. Michael Pierce, James H. Prestegard

Faculty Publications

N-Acetylglucosaminyltransferase V (GnT-V) is an enzyme involved in the biosynthesis of asparagine-linked oligosaccharides. It is responsible for the transfer of N-acetylglucosamine (GlcNAc) from the nucleotide sugar donor, uridine 5'-diphospho-N-acetylglucosamine (UDP-GlcNAc), to the 6 position of the α-1-6 linked Man residue in N-linked oligosaccharide core structures. GnT-V up-regulation has been linked to increased cancer invasiveness and metastasis and, appropriately, targeted for drug development. However, drug design is impeded by the lack of structural information on the protein and the way in which substrates are bound. Even though the catalytic domain of this type II membrane protein can be expressed in mammalian …

Alkalilimnicola Ehrlichii Sp. Nov., A Novel, Arsenite-Oxidizing Haloalkaliphilic Gammaproteobacterium Capable Of Chemoautotrophic Or Heterotrophic Growth With Nitrate Or Oxygen As The Electron Acceptor, Shelley E. Hoeft, Jodi Switzer Blum, John F. Stolz, F. Robert Tabita, Brian Witte, Gary M. King, Joanne M. Santini, Ronald S. Oremland

Faculty Publications

A facultative chemoautotrophic bacterium, strain MLHE-1T, was isolated from Mono Lake, an alkaline hypersaline soda lake in California, USA. Cells of strain MLHE-1T were Gram-negative, short motile rods that grew with inorganic electron donors (arsenite, hydrogen, sulfide or thiosulfate) coupled with the reduction of nitrate to nitrite. No aerobic growth was attained with arsenite or sulfide, but hydrogen sustained both aerobic and anaerobic growth. No growth occurred when nitrite or nitrous oxide was substituted for nitrate. Heterotrophic growth was observed under aerobic and anaerobic (nitrate) conditions. Cells of strain MLHE-1T could oxidize but not grow on CO, while CH4 neither …

Analysis Of A Decade In Library Literature: 1994-2004, Kelly D. Blessinger, Michelle Frasier-Robinson

Faculty Publications

The purpose of this study was to analyze trends in publication and citation in library and information science journals over a decade (1994-2004) of the literature. This examination revealed the areas of concentration within the research, frequently published subjects through the years, and the characteristics of the top-cited authors and resources during this time. This information allows those in the field to follow the trends in publication, gives researchers the tools to determine which journals might give their work the most exposure and recognition, and can help libraries to make collection management decisions in this subject area.

Distribution Of The Hiv Resistance Ccr5-Δ32 Allele Among Egyptians And Syrians, Abdel Halim Salem, Mark A. Batzer

Faculty Publications

A mutant allele of the β-chemokine receptor gene CCR5 bearing a 32-basepair (bp) deletion that prevents cell invasion by the primary transmitting strain of HIV-1 has recently been characterized. Individuals homozygous for the mutation are resistant to infection, even after repeated high-risk exposure, but this resistance appears not absolute, as isolated cases of HIV-positive deletion homozygotes are emerging. The consequence of the heterozygous state is not clear, but it may delay the progression to AIDS in infected individuals. In order to evaluate the frequency distribution of CCR5-Δ32 polymorphism among Egyptians, a total of 200 individuals (154 from Ismailia and 46 …

Production Of F1 Interspecies Hybrid Offspring With Cryopreserved Sperm From A Live-Bearing Fish, The Swordtail Xiphophorus Helleri, Huiping Yang, Leona Hazlewood, Sheila J. Heater, Paula A. Guerrero, Ronald B. Walter, Terrence R. Tiersch

Faculty Publications

Despite study of sperm cryopreservation in more than 200 fish species, production of broods from cryopreserved sperm in live-bearing fish has not been demonstrated. This has not been due to a lack of effort, but instead is a result of the unique morphology, biology, and biochemistry of reproduction in viviparous fishes. For example, sperm of Xiphophorus helleri have a cylindrical nucleus, can swim for days after being activated, have glycolytic capabilities, and can reside in the female reproduction tract for months before fertilization. These traits are not found in fishes with external fertilization. The long-standing research use of the genus …

Physiological, Ecological, And Phylogenetic Characterization Of Stappia, A Marine Co-Oxidizing Bacterial Genus, Carolyn F. Weber, Gary M. King

Faculty Publications

Bacteria play a major role in marine CO cycling, yet very little is known about the microbes involved. Thirteen CO-oxidizing Stappia isolates obtained from existing cultures, macroalgae, or surf samples representing geographically and ecologically diverse habitats were characterized using biochemical, physiological, and phylogenetic approaches. All isolates were aerobic chemoorganotrophs that oxidized CO at elevated (1,000 ppm) and ambient-to-subambient concentrations (<0.3 ppm). All contained the form I (OMP) coxL gene for aerobic CO dehydrogenase and also the form II (BMS) putative coxL gene. In addition, some strains possessed cbbL, the large subunit gene for ribulose-1,5-bisphosphate carboxylase/oxygenase, suggesting the possibility of lithotrophic or mixotrophic metabolism. All isolates used a wide range of sugars, organic acids, amino acids, and aromatics for growth and grew at salinities from 5 to 45 ppt. All but one isolate denitrified or respired nitrate. Phylogenetic analyses based on 16S rRNA gene sequences indicated that several isolates could not be distinguished from Stappia aggregata and contributed to a widely distributed species complex. Four isolates (of strains GA15, HI, MIO, and M4) were phylogenetically distinct from validly described Stappia species and closely related genera (e.g., Ahrensia, Pannonibacter, Pseudovibrio, and Roseibium). Substrate utilization profiles, enzymatic activity, and membrane lipid composition further distinguished these isolates and supported their designations as new Stappia species. The observed metabolic versatility of Stappia likely accounts for its cosmopolitan distribution and its ability to contribute to CO cycling as well as other important biogeochemical cycles.

Sex And Seasonal Co-Variation Of Arginine Vasotocin (Avt) And Gonadotropin-Releasing Hormone (Gnrh) Neurons In The Brain Of The Halfspotted Goby, Karen P. Maruska, Mindy H. Mizobe, Timothy C. Tricas

Faculty Publications

Gonadotropin-releasing hormone (GnRH) and arginine vasotocin (AVT) are critical regulators of reproductive behaviors that exhibit tremendous plasticity, but co-variation in discrete GnRH and AVT neuron populations among sex and season are only partially described in fishes. We used immunocytochemistry to examine sexual and temporal variations in neuron number and size in three GnRH and AVT cell groups in relation to reproductive activities in the halfspotted goby (Asterropteryx semipunctata). GnRH-immunoreactive (-ir) somata occur in the terminal nerve, preoptic area, and midbrain tegmentum, and AVT-ir somata within parvocellular, magnocellular, and gigantocellular regions of the preoptic area. Sex differences were found among all …

Snell's Law Of Refraction Observed In Thermal Frontal Polymerization, John A. Pojman, Veronika Viner, Burcu Binici, Shanna Lavergne, Melanie Winsper, Dmitry Golovaty, Laura Gross

Faculty Publications

We demonstrate that Snell's law of refraction can be applied to thermal fronts propagating through a boundary between regions that support distinct frontal velocities. We use the free-radical frontal polymerization of a triacrylate with clay filler that allows for two domains containing two different concentrations of a peroxide initiator to be molded together. Because the polymerization reaction rates depend on the initiator concentration, the propagation speed is different in each domain. We study fronts propagating in two parallel strips in which the incident angle is 90°. Our data fit Snell's law vr vi = sin θr sin θi, where vr …
