Bovine Trichomoniasis, Russ Daly

Range Beef Cow Symposium

Trichomoniasis is a venereal disease of cattle that has caused significant economic losses in American cattle herds for many years. Its return to prominence in South Dakota in 2004-2005 is contrasted by the long-standing more endemic nature of the disease in other western states. The rate of diagnosis of trichomoniasis in the region has increased in recent years; whether this is due to an actual increase in numbers of affected herds or simply heightened awareness of the disease is not clear.

Few detailed studies have been conducted to determine the actual prevalence of trichomoniasis in U.S. herds, but a 1990 …

Putting Bvd Control On Your Radar Screen, Jim Kennedy

Range Beef Cow Symposium

Bovine viral diarrhea virus (BVDV) is a major viral disease impacting beef cattle reproduction and performance. The key source of BVDV infection is the BVDV PI animal. PI animals are the result of fetal exposure to the virus prior to the development of its immune system approximately between day 18 and day 125 of gestation. Exposure to the virus prior to day 18 may result in embryonic death and apparent infertility, while exposure after day 125 is more commonly associated with abortion, stillbirths or congenital abnormalities. BVDV not only lessens reproductive performance but also produces disease in cattle including diarrhea, …

“Decoding” The Alphabet Soup Of Animal I.D. And Marketing Programs, Jack C. Whittier

Range Beef Cow Symposium

Wow! What a difference two years makes. At the Range Beef Cow Symposium in 2003, we endeavored to address the topic “Traceback, Verification, and Animal Identification on the Ranch: Big Brother of Best Buddy?” On the very day of this presentation, December 9, 2005, a Holstein cow in the state of Washington was harvested and due to abnormalities observed in this cow, tissue samples were taken for further evaluation. Later that month, on December 23, 2003, it was announced that this cow tested positive for bovine spongiform encephalopathy (BSE). This event, along with associated policy from USDA, combined to rocket …

Key Indicators Of Success In Ranching: A Balanced Approach, Barry H. Dunn, Matthew Etheredge

Range Beef Cow Symposium

While it has often been recognized that a ranch is greater than the sum of its parts, measuring and reporting the performance of the parts seems to be the common method of measuring the success of a ranch. Depending on the interest of the owner and manager, emphasis may be focused on cattle performance, or range management, or financial performance, or individual or personal accomplishments. Seldom does the discussion of success encompass some overarching measurement. The management tool known as “The Balanced Scorecard,” first developed by Robert S. Kaplin and David P. Norton in the early 1990s (Kaplin and Norton, …

Conformational Studies Of The Tetramerization Site Of Human Erythroid Spectrin By Cysteine-Scanning Spin-Labeling Epr Methods, Shahila Mehboob, Bing Hao Luo, Wentao Fu, Michael E. Johnson, L. W.M. Fung

Faculty Publications

We used cysteine-scanning and spin-labeling methods to prepare singly spin labeled recombinant peptides for electron paramagnetic resonance studies of the partial domain regions at the tetramerization site (N-terminal end of α and C-terminal end of β) of erythroid spectrin. The values of the inverse line width parameter (ΔH0-1) from a family of SpoI-1-368Δ peptides scanning residues 21-30 exhibited a periodicity of ∼3.5-4. We used molecular dynamics calculations to show that the asymmetric mobility of this helix is not necessarily due to tertiary contacts, but is likely due to intrinsic properties of helix C′, a helix with a heptad pattern sequence. …

The Relationship Between Frq-Protein Stability And Temperature Compensation In The Neurospora Circadian Clock, Peter Ruoff, Jennifer J. Loros, Jay C. Dunlap

Dartmouth Scholarship

Temperature compensation is an important property of all biological clocks. In Neurospora crassa, negative-feedback regulation on the frequency (frq) gene's transcription by the FRQ protein plays a central role in the organism's circadian pacemaker. Earlier model calculations predicted that the stability of FRQ should determine the period length of Neurospora's circadian rhythm as well as the rhythm's temperature compensation. Here, we report experimental FRQ protein stabilities in frq mutants at 20 degrees C and 25 degrees C, and estimates of overall activation energies for mutant FRQ protein degradation. The results are consistent with earlier model predictions, i.e., temperature compensation of …

The Runnins Report

Watershed Access Lab Projects

For the past 4 years, students in AP Biology have performed summer Ecology research studies at Burr’s Pond in Seekonk. One goal of the summer research has been to provide the students with a relevant, meaningful inquiry-based learning experience. At the start of the school year, the students measure the dissolved oxygen as part of the required AP Laboratory Exercise 12. A second goal of the summer research has been to sustain an annual evaluation of the dissolved oxygen as well as the diversity and distribution of organisms in and around the pond. Unfortunately, the data is not very accurate …

On The Use Of Non-Euclidean Isotropy In Geostatistics, Frank C. Curriero

Johns Hopkins University, Dept. of Biostatistics Working Papers

This paper investigates the use of non-Euclidean distances to characterize isotropic spatial dependence for geostatistical related applications. A simple example is provided to demonstrate there are no guarantees that existing covariogram and variogram functions remain valid (i.e.\ positive definite or conditionally negative definite) when used with a non-Euclidean distance measure. Furthermore, satisfying the conditions of a metric is not sufficient to ensure the distance measure can be used with existing functions. Current literature is not clear on these topics. There are certain distance measures that when used with existing covariogram and variogram functions remain valid, an issue that is explored. …

Making Sense Of Nanocrystal Lattice Fringes, Phil Fraundorf, Wentao Qin, Peter Moeck, Eric Mandell

Physics Faculty Works

The orientation dependence of thin-crystal lattice fringes can be gracefully quantified using fringe-visibility maps, a direct-space analog of Kikuchi maps [Nishikawa and Kikuchi, Nature (London) 121, 1019 (1928)]. As in navigation of reciprocal space with the aid of Kikuchi lines, fringe-visibility maps facilitate acquisition of crystallographic information from lattice images. In particular, these maps can help researchers to determine the three-dimensional lattice of individual nanocrystals, to “fringe-fingerprint” collections of randomly oriented particles, and to measure local specimen thickness with only a modest tilt. Since the number of fringes in an image increases with maximum spatial-frequency squared, these strategies (with help …

Top-Down Structure And Device Fabrication Using In Situ Nanomachining, Xiaodong Li, Xinnan Wang, Qihua Xiong, Peter C. Eklund

Faculty Publications

We demonstrate the potential of an alternative tool for the fabrication of nanoscale structures and devices. A nanoindenter integrated with an atomic force microscope is shown to be a powerful machine tool for cutting precise length nanowires or nanobelts and for manipulating the shortened wires. We also demonstrate its utility in cutting grooves and fabricating dents (or periodic arrays of dents) in ZnSnanobelts. This approach permits the direct mechanical machining of nanodevices that are supported on a substrate without the inherent complications of e beam or photolithography.

Patterns Of Risk And Trajectories Of Preschool Problem Behaviors: A Person-Oriented Analysis Of Attachment In Context, Thomas E. Keller, Susan J. Spieker, Lewayne D. Gilchrist

School of Social Work Faculty Publications and Presentations

A small proportion of children exhibit extreme and persistent conduct problems through childhood. The present study employed the multiple-domain model of Greenberg and colleagues as the framework for person-oriented analyses examining whether parents' child attachment combines with parenting, family ecology, and child characteristics in particular configurations of risk that are linked to this problematic developmental pathway. Using prospective data from a community sample of adolescent mothers and their children, latent variable growth mixture modeling identified a normative trajectory with declining problem behaviors during the preschool period. Consistent with research on early-starter pathways, a distinct group of children featured a higher …

Computer-Assisted Docking Of Flavodoxin With The Atp:Co(I)Rrinoid Adenosyltransferase (Coba) Enzyme Reveals Residues Critical For Protein-Protein Interactions But Not For Catalysis*, Nicole R. Buan, Jorge C. Escalante-Semerena

Department of Biochemistry: Faculty Publications

The activity of the housekeeping ATP:co(I)rrinoid adenosyltransferase (CobA) enzyme of Salmonella enterica sv. Typhimurium is required to adenosylate de novo biosynthetic intermediates of adenosylcobalamin and to salvage incomplete and complete corrinoids from the environment of this bacterium. In vitro, reduced flavodoxin (FldA) provides an electron to generate the co(I)rrinoid substrate in the CobA active site. To understand how CobAand FldA interact, a computer model of aCobA∙FldA complex was generated. This model was used to guide the introduction of mutations into CobA using site-directed mutagenesis and the synthesis of a peptide mimic of FldA. Residues Arg-9 and Arg-165 of CobA …
