Unification Of Variance Components And Haseman-Elston Regression For Quantitative Trait Linkage Analysis, Wei-Min Chen, Karl W. Broman, Kung-Yee Liang

Johns Hopkins University, Dept. of Biostatistics Working Papers

Two of the major approaches for linkage analysis with quantitative traits in humans include variance components and Haseman-Elston regression. Previously, these have been viewed as quite separate methods. We describe a general model, fit by use of generalized estimating equations (GEE), for which the variance components and Haseman-Elston methods (including many of the extensions to the original Haseman-Elston method) are special cases, corresponding to different choices for a working covariance matrix. We also show that the regression-based test of Sham et al.(2002) is equivalent to a robust score statistic derived from our GEE approach. These results have several important implications. …

Evaluation Of Adsorption Effects On Measurements Of Ammonia, Acetic Acid, And Methanol, Robert J. Yokelson, Ted J. Christian, Isaac T. Bertschi, Wei M. Hao

Chemistry and Biochemistry Faculty Publications

[1] We examined how adsorption and desorption of gases from inlets and a cell could affect the accuracy of closed-cell FTIR measurements of carbon dioxide (CO₂), carbon monoxide (CO), methane (CH₄), nitric oxide (NO), nitrogen dioxide (NO₂), methanol (CH₃OH), acetic acid (CH₃COOH), and ammonia (NH₃). When standards were delivered to the cell through a stainless steel inlet, temporarily reduced transmission was observed for CH₃OH and NH₃. However, a halocarbon wax coated inlet (normally used on the system) had excellent transmission (comparable to room temperature …

Are Biotech Crops And Conventional Crops Like Products? An Analysis Under Gatt, Julian Wong

Duke Law & Technology Review

The transatlantic debate over the use of genetically modified organisms ("GMO"s) as food products, with the US as a proponent on one side, and the European Union ("EU") as an opponent on the other, is set to take center stage. The US has initiated formal legal action under the World Trade Organization Dispute Settlement System, charging that the EU violates several agreements of international trade law, including Article III of GATT, an anti-protectionist measure which forbids a country from favoring its own products over imported "like products." The US claims that GMOs and conventional crops are "like products,, and that …

Coastal Observatory Investigates Energetic Current Oscillations On Southeast Florida Shelf, Alexander Soloviev, Rebekah J. Walker, Robert H. Weisberg, Mark E. Luther

Marine & Environmental Sciences Faculty Articles

Coastal circulation along the southeast Florida shelf is strongly related to the dynamics of the Florida Current. The current follows the steep bottom terrain along the shelf break separating the deep ocean from the coastal zone (Figure 1 a, b). Energetic and complex flow regimes arise along the current's western edge, causing transient features such as sub-meso-scale eddies [Lee and Mayer, 1977; Shay et al., 2000] and energetic internal oscillations [Mooers, 1975; Soloviev et al., 2003], which affect mixing between the shelf and deeper ocean waters. Understanding of these regimes is important for modeling and prediction of the …

Generation And Sequence Characterization Of A Normalized Cdna Library From Swine Ovarian Follicles, Alexandre R. Caetano, Rodger K. Johnson, Daniel Pomp

Department of Animal Science: Faculty Publications

Ovulation rate is a major factor determining litter size in swine and is, therefore, a trait of economic importance to the pork industry. The dynamics of follicle development, which in turn are dictated by a balance between follicle recruitment, maturation, selection, and atresia, are a major determining factor of ovulation rate. The role of several genes expressed in the ovaries during these processes has been described, but studies utilizing large-scale genomic approaches have yet to be conducted to examine gene expression in this tissue more globally. We have developed a normalized cDNA library from swine ovarian follicles in various stages …

Magnetic Storage Device Using Induced Magnetic Reversal Of A Cobalt Element Array, Hanning Chen, Scott L. Whittenburg

Chemistry and Biochemistry Faculty Publications

The effects of the applied field, cell size, and cutting area on the ‘‘seed’’ induced magnetic reversal of a cobalt element array have been studied by a stochastic dynamic micromagnetics code using the Laudau–Lifshitz–Gilbert equation. Three magnetic reversal mechanisms under different magnitudes of the applied field have been investigated by examining the energy profiles. To minimize the effect of the thermal fluctuations on the switching time, an applied field with magnitude around 0.7 or 0.8 T and an element array with cutting area less than 10 nm X 10 nm are required. By using the smaller cellsize, the switching time …

Il-23 Produced By Cns-Resident Cells Controls T Cell Encephalitogenicity During The Effector Phase Of Experimental Autoimmune Encephalomyelitis, Burkhard Becher, Brigit G. Durell, Randolph J. Noelle

Dartmouth Scholarship

CNS-resident cells, in particular microglia and macrophages, are a source of inflammatory cytokines during inflammation within the CNS. Expression of IL-23, a recently discovered cytokine, has been shown to be critical for the development of experimental autoimmune encephalomyelitis (EAE) in mice. Expression of the p40 subunit of IL-12 and IL-23 by microglia has been shown in situ and in vitro, but direct evidence for a functional significance of p40 expression by CNS cells during an immune response in vivo is still lacking. Here we report that p40 plays a critical role in maintaining encephalitogenicity during the disease course. By using …

Environmental Indicator Report: Shellfish, Phil Trowbridge

PREP Reports & Publications

During the fall and winter of 2001-2002, the New Hampshire Estuaries Project’s Technical Advisory Committee (TAC) developed a suite of environmental indicators to track progress toward the NHEP’s management goals and objectives. These indicators were fully described in terms of their performance criteria, statistical methods, and measurable goals in the NHEP’s Monitoring Plan published in March 2003 (NHEP, 2003). From September 2002 to April 2003, the NHEP Coastal Scientist prepared four “Indicator Reports” that summarized the available information and results of statistical tests for each of the indicators. The TAC reviewed and commented on these reports, and then recommended a …

I thank you, each of you, for making that true.

Skeletal Myosin Heavy Chain Function In Cultured Lung Myofibroblasts, Nancy A. Rice, Leslie A. Leinwand

Biology Faculty Publications

Myofibroblasts are unique contractile cells with both muscle and nonmuscle properties. Typically myofibroblasts are identified by the expression of smooth muscle actin (ASMA); however some myofibroblasts also express sarcomeric proteins. In this study, we show that pulmonary myofibroblasts express three of the eight known sarcomeric myosin heavy chains (MyHCs) (IIa, IId, and embryonic) and that skeletal muscle myosin enzymatic activity is required for pulmonary myofibroblast contractility. Furthermore, inhibition of skeletal myosin activity and myofibroblast contraction results in a decrease in both ASMA and skeletal MyHC promoter activity and ASMA protein expression, suggesting a potential coupling of skeletal myosin activity and …

A Role For Yip1p In Copii Vesicle Biogenesis, Matthew Heidtman, Catherine Z. Chen, Ruth N. Collins, Charles Barlowe

Dartmouth Scholarship

Yeast Ypt1p-interacting protein (Yip1p) belongs to a conserved family of transmembrane proteins that interact with Rab GTPases. We encountered Yip1p as a constituent of ER-derived transport vesicles, leading us to hypothesize a direct role for this protein in transport through the early secretory pathway. Using a cell-free assay that recapitulates protein transport from the ER to the Golgi complex, we find that affinity-purified antibodies directed against the hydrophilic amino terminus of Yip1p potently inhibit transport. Surprisingly, inhibition is specific to the COPII-dependent budding stage. In support of this in vitro observation, strains bearing the temperature-sensitive yip1-4 allele accumulate ER membranes …

A Nested Unsupervised Approach To Identifying Novel Molecular Subtypes, Elizabeth Garrett, Giovanni Parmigiani

Johns Hopkins University, Dept. of Biostatistics Working Papers

In classification problems arising in genomics research it is common to study populations for which a broad class assignment is known (say, normal versus diseased) and one seeks to find undiscovered subclasses within one or both of the known classes. Formally, this problem can be thought of as an unsupervised analysis nested within a supervised one. Here we take the view that the nested unsupervised analysis can successfully utilize information from the entire data set for constructing and/or selecting useful predictors. Specifically, we propose a mixture model approach to the nested unsupervised problem, where the supervised information is used to …

Estimates Of Genetic Parameters And Selection Strategies To Improve The Economic Efficiency Of Postweaning Growth In Lambs, G. D. Snowder, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

The objectives of this study were to estimate (co)variance components for growth and feed efficiency measures, and to compare selection strategies to improve economic efficiency of gain. Variance components for pre- and postweaning growth, body weight, and measures of feed efficiency were estimated from data collected on 1,047 Targhee lambs over 7 yr. Approximately 21 d after weaning, lambs were group-fed for 4 wk, with ad libitum access to a diet of 37% whole barley grain and 63% pelleted alfalfa hay. Lambs were then individually fed for 6 wk. Lambs were then returned to group feeding for another 4-wk period. …

Runoff And Sediment Losses From Annual And Unusual Storm Events From The Alto Experimental Watersheds, Texas: 23 Years After Silvicultural Treatments, Matthew W. Mcbroom, R Scott Beasley, Mingteh Chang, Brian Gowin, George G. Ice

Faculty Publications

Evaluating the potential impacts of intensive silvicultural practices on water quality is critical for establishing the long-term sustainability of contemporary forest management practices. From 1979 to 1985, a study involving nine small (~2.5 ha) forested watersheds was conducted near Alto, Texas in the upper western Gulf-Coastal Plain to evaluate the impacts then-current silvicultural practices on water quality. In the years following the study, silvicultural Best Management Practices (BMPs) including Streamside Management Zones (SMZs) and other erosion control practices evolved and questions arose about the applicability of earlier results to current practices. In 1999, these same watersheds were reinstrumented to evaluate …
