Jacobson, Yuan Xiang Meng, Philip E. Pellett, Lawrence A. Kingsley, Konstantin G. Kousoulas, Abolghasem Baghian, Charles R. Rinaldo

Faculty Publications

T cell immunity to lytic proteins of herpesviruses is important in host control of infection. We have characterized the cytotoxic T lymphocyte (CTL) response to 5 human herpesvirus 8 (HHV-8) homologues of lytic proteins in HHV-8-seropositive individuals. HLA class I-restricted, CD8+ CTL responses to ≥1 HHV-8 lytic protein were detected in all 14 HHV-8-seropositive study subjects tested, with or without human immunodeficiency virus type 1 (HIV-1) infection, but not in any of 5 HHV-8-seronegative individuals. Seven of these study subjects with both HHV-8 and HIV-1 infection had greater anti-CTL reactivity to glycoprotein H (open-reading frame 22) than did the 7 …

Safety Of Brucella Abortus Strain Rb51 In Bull Elk, Walter E. Cook, Elizabeth S. Williams, E. Tom Thorne, Terry J. Kreeger, Glenn W. Stout, Gerhardt Schurig, Lesley A. Colby, Fred Enright, Philip H. Elzer Jan 2000

Safety Of Brucella Abortus Strain Rb51 In Bull Elk, Walter E. Cook, Elizabeth S. Williams, E. Tom Thorne, Terry J. Kreeger, Glenn W. Stout, Gerhardt Schurig, Lesley A. Colby, Fred Enright, Philip H. Elzer

Faculty Publications

Some of the elk (Cervus elaphus nelsoni) of the Greater Yellowstone Area (Wyoming, Idaho, Montana; USA) are infected with Brucella abortus, the bacterium that causes bovine brucellosis. Brucella abortus strain RB51 vaccine is being considered as a means to control B. abortus induced abortions in cow elk. However, the most probable vaccination strategies for use in free-ranging elk might also result in some bull elk being inoculated, thus, it is important to insure that the vaccine is safe in these animals. In the winter of 1995, 10 free-ranging bull elk calves were captured, tested for B. abortus antibodies, and intramuscularly …

Faculty Publications

Respiratory tract infections with viruses and Pasteurella spp. were determined sequentially among 26 cattle that died during two severe epizootics of shipping fever pneumonia. Nasal swab and serum samples were collected prior to onset of the epizootics, during disease progression, and after death, when necropsies were performed and lung samples were collected. Eighteen normal control cattle also were sampled at the beginning of the epizootics as well as at weekly intervals for 4 weeks. Respiratory bovine coronaviruses (RBCV) were isolated from nasal secretions of 21 and 25 cattle before and after transport. Two and 17 cattle nasally shed Pasteurella spp. …

Effects Of Light Restriction On Broiler Performance And Specific Body Structure Measurements, D. R. Ingram, L. F. Hatten, B. N. Mcpherson Jan 2000

Effects Of Light Restriction On Broiler Performance And Specific Body Structure Measurements, D. R. Ingram, L. F. Hatten, B. N. Mcpherson

Faculty Publications

This experiment was conducted over a 42-day period to determine the effect of light restriction on performance parameters and specific body structure measurements of male broilers. The two light treatments studied were 23 hr light: 1 hr dark (control) and 12 hr light: 12 hr dark (restricted). Measurements taken during the experiment were body weight, feed conversion, livability, length of shank and keel, and tibiotarsal weight and strength. The results of this experiment showed that light restriction significantly decreased body weight but significantly improved feed conversion. Additionally, shank length was significantly decreased by light restriction. Keel length and tibiotarsal weight …

Safety And Efficacy Of Brucella Abortus Strain Rb51 Vaccine In Captive Pregnant Elk, Terry J. Kreeger, Michael W. Miller, Margaret A. Wild, Philip H. Elzer, Steven C. Olsen Jan 2000

Safety And Efficacy Of Brucella Abortus Strain Rb51 Vaccine In Captive Pregnant Elk, Terry J. Kreeger, Michael W. Miller, Margaret A. Wild, Philip H. Elzer, Steven C. Olsen

Faculty Publications

Brucella abortus strain RB51 is a laboratory-derived rough mutant of virulent B. abortus strain 2308 used as a vaccine because it induces antibodies that do not react on standard brucellosis serologic tests. Strain RB51 vaccine was evaluated in pregnant captive elk (Cervus elaphus) to determine (1) if it induced abortion and (2) if it protected against abortion following subsequent challenge. The time period of this study (February-June, 1998) was similar to field conditions where elk are vaccinated and possibly exposed to B. abortus. Fourteen elk were randomly and equally divided into vaccinated and control groups. The vaccinated group was vaccinated …

Influence Of Mechanical Processing On Utilization Of Corn Silage By Lactating Dairy Cows, T. R. Dhiman, M. A. Bal, Z. Wu, V. R. Moreira, R. D. Shaver, L. D. Satter, K. J. Shinners, R. P. Walgenbach Jan 2000

Influence Of Mechanical Processing On Utilization Of Corn Silage By Lactating Dairy Cows, T. R. Dhiman, M. A. Bal, Z. Wu, V. R. Moreira, R. D. Shaver, L. D. Satter, K. J. Shinners, R. P. Walgenbach

Faculty Publications

We conducted three experiments to determine the influence of mechanical processing on corn silage utilization by lactating dairy cows. Total mixed rations contained either unprocessed or processed corn silage harvested between 1/4 and 3/4 milk line. In trial 1, 12 multiparous Holstein cows were used in a replicated double switchback design with 21-d periods. Intake of dry matter (DM) was increased 1.2 kg/d by processing, but milk yield was unaffected. Processing did not affect apparent total-tract DM digestibility, but processing tended to lower starch and corn excretion in feces and reduced concentration of sieved corn kernel particles in feces. In …

The Effect Of Dietary Betaine In Eimeria Acervulina-Infected Chicks, J. O. Matthews, L. L. Southern Jan 2000

The Effect Of Dietary Betaine In Eimeria Acervulina-Infected Chicks, J. O. Matthews, L. L. Southern

Faculty Publications

Two experiments were conducted to evaluate the effect of dietary betaine in broiler chicks with either chronic (CHR; 2.5 x 105 sporulated oocysts on Day 1,4,7, and 10) or acute (ACT; 1.0 x 106 sporulated oocysts on Day 1) Eimeria acervulina infections. Three hundred (Experiment 1) or 600 (Experiment 2), 4-d-old male chicks were used in the 14-d experiments. In both experiments, a 2 x 3 factorial arrangement of treatments was used: two levels of betaine (0 or 0.075%) and three levels of coccidiosis infection (uninfected, CHR, or ACT). Each treatment was replicated five (Experiment 1) or 10 (Experiment 2) …

The Effect Of Varying Mix Uniformity (Simulated) Of Phytase On Growth Performance, Mineral Retention, And Bone Mineralization In Chicks, S. L. Johnston, L. L. Southern Jan 2000

The Effect Of Varying Mix Uniformity (Simulated) Of Phytase On Growth Performance, Mineral Retention, And Bone Mineralization In Chicks, S. L. Johnston, L. L. Southern

Faculty Publications

An 18-d experiment was conducted to determine the effect of varying mix uniformity of phytase on growth performance, mineral retention, and bone mineralization in chicks. Chicks (initial and final weights were 74.5 and 803.3 g) were allotted to seven treatments with six (Treatment 1) or seven (Treatments 2 to 7) replicates of seven chicks per replicate in a completely randomized design. Varying mix uniformity of phytase was simulated by alternately providing two diets with two different concentrations of microbial phytase; the diets were switched every 24 h. Treatments were: 1) positive control (CON) (Ca, 1.0%; available phosphorus (aP), 0.45%), 2) …

The Distribution Of Human Genetic Diversity: A Comparison Of Mitochondrial, Autosomal, And Y-Chromosome Data, Lynn B. Jorde, W. S. Watkins, M. J. Bamshad, M. E. Dixon, C. E. Ricker, M. T. Seielstad, M. A. Batzer

Faculty Publications

We report a comparison of worldwide genetic variation among 255 individuals by using autosomal, mitochondrial, and Y-chromosome polymorphisms. Variation is assessed by use of 30 autosomal restriction-site polymorphisms (RSPs), 60 autosomal short-tandem-repeat polymorphisms (STRPs), 13 Alu-insertion polymorphisms and one LINE-1 element, 611 bp of mitochondrial control-region sequence, and 10 Y-chromosome polymorphisms. Analysis of these data reveals substantial congruity among this diverse array of genetic systems. With the exception of the autosomal RSPs, in which an ascertainment bias exists, all systems show greater gene diversity in Africans than in either Europeans or Asians. Africans also have the largest total number of …

Faculty Publications

A number of serological tests were compared for the detection of antibodies to Brucella abortus in bison (Bison bison). The performance of the fluorescence polarization assay (FPA) in both the preliminary evaluation and a subsequent blind validation indicated that this test was the most suitable for serological diagnosis of brucellosis in bison. The sensitivity and specificity in the preliminary evaluation were 92.1% and 99.4%, respectively. The sensitivity and specificity in a subsequent blind study were 96.3% and 97.6%, respectively. In a double blind study conducted on bison vaccinated with B. abortus strain 19, the data suggests that the FPA can …

Faculty Publications

A multiplex amplification and detection platform for the diagnosis of Mycobacterium bovis and Brucella abortus infection simultaneously in bovine milk and nasal secretions was developed. This system (designated the bovine pathogen detection assay [BPDA]-PCR) consists of duplex amplification of species-specific targets (a region of the BCSP31K gene of B. abortus and a repeat-sequence region in the hsp65 gene of M. bovis, respectively). This is followed by a solid-phase probe capture hybridization of amplicons for detection. On the basis of spiking experiments with normal milk, the analytical sensitivity of the assay was 800 CFU equivalents/ml of milk for B. abortus and …

A Judicious Solution: The Criminal Law Committee Draft Redefinition Of The Loss Concept In Economic Crime Sentencing, Frank O. Bowman Iii Jan 2000

A Judicious Solution: The Criminal Law Committee Draft Redefinition Of The Loss Concept In Economic Crime Sentencing, Frank O. Bowman Iii

Faculty Publications

In December 1999, the United States Sentencing Commission (Commission), an institution that had been in suspended animation for over a year with all seven voting seats vacant, fluttered its eyelids and came back to life. An agreement between the Senate and the White House produced seven new Commissioners: five sitting federal judges, the former General Counsel of the Commission, and a law professor. The new group began work immediately, making itself accessible in meetings with lawyers and judges around the country, exuding an air of intelligence and collegiality, and dispensing in short order with a backlog of amendments to the …

Completing The Sentencing Revolution: Reconsidering Sentencing Procedure In The Guidelines Era, Frank O. Bowman Iii Jan 2000

Completing The Sentencing Revolution: Reconsidering Sentencing Procedure In The Guidelines Era, Frank O. Bowman Iii

Faculty Publications

The central innovation of the guidelines sentencing revolution has been the creation of a regime in which facts other than those required for conviction have necessary consequences at sentencing. In days of yore, judges mulling a sentence were entitled to receive information from virtually any source on virtually any subject, but they were never obliged to pass public judgment on the truth or falsity of what they heard because no finding of fact could constrain their discretion to set a sentence anywhere within the boundaries set by statutory maxima and minima. No more. The project of the original United States …

Charitable Choice And The Critics, Carl H. Esbeck Jan 2000

Charitable Choice And The Critics, Carl H. Esbeck

Faculty Publications

First, the statute prohibits the government from discriminating with regard to religion when determining whether providers are eligible to deliver social services under these programs. Second, the statute imposes on government the duty not to intrude into the religious autonomy of faith-based providers. Third, the statute imposes on both government and participating FBOs the duty not to abridge certain rights of the ultimate beneficiaries of these programs. I will touch on these three principles below, and do so in reverse order.

Toward More Sophisticated Mediation Theory, John M. Lande Jan 2000

Toward More Sophisticated Mediation Theory, John M. Lande

Faculty Publications

In the lead article in this symposium, Professor Jeffrey Stempel provides a very thoughtful analysis of the mediation field. He focuses on the debate over facilitative and evaluative mediation and he is critical of many of the arguments made by proponents of facilitative mediation. I have expressed some similar concerns, and I generally agree with his analysis (with a quibble here and there). I do think that the facilitation-evaluation debate has been productive (though admittedly wearisome), and that proponents of facilitative mediation deserve more credit than he gives them in his article.

Statutory Rape Law And Enforcement In The Wake Of Welfare Reform, Rigel C. Oliveri Jan 2000

Statutory Rape Law And Enforcement In The Wake Of Welfare Reform, Rigel C. Oliveri

Faculty Publications

The recent national efforts at reforming the welfare system and new research on the connection between teen pregnancy and statutory rape have led many states to enact stricter laws against statutory rape and to increase the enforcement of existing laws. Punitive statutory rape laws are being viewed more and more as a mechanism for shrinking the welfare rolls by reducing teen pregnancy. Rigel Oliveri documents the resurgence of statutory rape law and enforcement and explores the ramifications it will have on teen parents. In particular, Oliveri approaches the issue from several analytical frameworks, discussing arguments for consent-based standards, the privacy …

The Quiet Demise Of Deference To Custom: Malpractice Law At The Millenium, Philip G. Peters Jr. Jan 2000

The Quiet Demise Of Deference To Custom: Malpractice Law At The Millenium, Philip G. Peters Jr.

Faculty Publications

According to conventional wisdom, tort law allows physicians to set their own standard of care. While defendants in ordinary tort actions are expected to exercise reasonable care under the circumstances, physicians traditionally have needed only to conform to the customs of their peers. However, judicial deference to physician customs is eroding. Gradually, quietly and relentlessly, state courts are withdrawing this legal privilege. Already, a dozen states have expressly rejected deference to medical customs and another nine, although not directly addressing the role of custom, have rephrased their standard of care in terms of the reasonable physician, rather than compliance with …

Constitutional Gravity: A Unitary Theory Of Alternative Dispute Resolution And Public Civil Justice, Richard C. Reuben Jan 2000

Constitutional Gravity: A Unitary Theory Of Alternative Dispute Resolution And Public Civil Justice, Richard C. Reuben

Faculty Publications

Under the traditional bipolar model, civil dispute resolution is generally divided into two spheres: trial, which is public in nature and therefore subject to constitutional due process, and alternative dispute resolution (ADR), which is private in nature and therefore not subject to such constraints. In this article, Professor Richard Reuben proposes a unitary understanding of public civil dispute resolution, one that recognizes that ADR is often energized by state action and thus is constitutionally required to comply with minimal but meaningful due process standards. Depending upon the process, such standards might include the right to an impartial forum, the right …

The Insurer's Right To Reimbursement Of Defense Costs, Robert H. Jerry Ii Jan 2000

The Insurer's Right To Reimbursement Of Defense Costs, Robert H. Jerry Ii

Faculty Publications

This Article examines the theoretical justification for the insurer's asserted right to reimbursement of defense costs incurred in defending noncovered claims. Part I sketches some details about the duty to defend which are necessary prerequisites to exploring any claim to a right of reimbursement. Part II discusses the rationale offered by most courts and commentators for recognizing the right to reimbursement: under the law of restitution, the insurer who defends a noncovered claim bestows a benefit on the policyholder which, in justice, ought to be returned. This Part concludes that a reasoned argument can be made in support of the …

Low-Temperature Nmr Studies Of Srb6, J. L. Gavilano, B. Ambrosini, H. R. Ott, D. P. Young, Z. Fisk Jan 2000

Low-Temperature Nmr Studies Of Srb6, J. L. Gavilano, B. Ambrosini, H. R. Ott, D. P. Young, Z. Fisk

Faculty Publications

We report the results of a 11B nuclear magnetic resonance (NMR) study of SrB6 at temperatures between 0.1 and 30 K and in a magnetic field of 4.74 T. Below 30 K the NMR spectrum is temperature independent but the spin-lattice relaxation rate T1-1 exhibits different features in two different temperature regimes. At high temperatures, between 30 K and a field-dependent crossover temperature TB between 0.5 and 2 K, T1-1 is almost temperature independent. We point out that for T in the crossover temperature range the magnitude of T1l-1 of SrB6 is distinctly larger than for LaB6, a metal with …

Gap-Anisotropic Model For The Narrow-Gap Kondo Insulators, Juana Moreno, P. Coleman Jan 2000

Gap-Anisotropic Model For The Narrow-Gap Kondo Insulators, Juana Moreno, P. Coleman

Faculty Publications

A theory is presented which accounts for the dynamical generation of a hybridization gap with nodes in the Kondo insulating materials CeNiSn and CeRhSb. We show that Hund’s interactions acting on virtual 4f2 configurations of the cerium ion can act to dynamically select the shape of the cerium ion by generating a Weiss field which couples to the shape of the ion. In low symmetry crystals where the external crystal fields are negligible, this process selects a nodal Kondo semimetal state as the lowest energy configuration. © 2000 The American Physical Society.

Interlayer Quasiparticle Transport In The Vortex State Of Josephson Coupled Superconductors, I. Vekhter, L. N. Bulaevskii, A. E. Koshelev, M. P. Maley Jan 2000

Interlayer Quasiparticle Transport In The Vortex State Of Josephson Coupled Superconductors, I. Vekhter, L. N. Bulaevskii, A. E. Koshelev, M. P. Maley

Faculty Publications

We calculate the dependence of the interlayer quasiparticle conductivity, σq, in a Josephson coupled d-wave superconductor on the magnetic field B∥c and the temperature T. We consider a clean superconductor with resonant impurity scattering and a dominant coherent interlayer tunneling. When pancake vortices in adjacent layers are weakly correlated, at low T the conductivity increases sharply with B over a field scale determined by the impurity scattering, before reaching an extended region of slow linear growth. At high T the conductivity initially decreases and then reaches the same linear regime. For correlated pancakes, σq increases much more strongly with the …

Angle-Dependent Magnetothermal Conductivity In D-Wave Superconductors, I. Vekhter, P. J. Hirschfeld Jan 2000

Angle-Dependent Magnetothermal Conductivity In D-Wave Superconductors, I. Vekhter, P. J. Hirschfeld

Faculty Publications

We analyse the behavior of the thermal conductivity, κ(H), in the vortex state of a quasi-two-dimensional d-wave superconductor when both the heat current and the applied magnetic field are in the basal plane. At low temperature the effect of the field is accounted for in a semiclassical approximation, via a Doppler shift in the spectrum of the nodal quasiparticles. In that regime κ(H) exhibits twofold oscillations as a function of the angle between the direction of the field in the plane and the direction of the heat current, in agreement with experiment. © 2000 Elsevier Science B.V.

Thermal Conductivity In The Vortex State Of D-Wave Superconductors, I. Vekhter, A. Houghton Jan 2000

Thermal Conductivity In The Vortex State Of D-Wave Superconductors, I. Vekhter, A. Houghton

Faculty Publications

We present the results of a microscopic calculation of the longitudinal thermal conductivity of quasiparticles, κxx, in a 2D d-wave superconductor in the vortex state. Our approach takes into account both impurity scattering and a contribution to the thermal transport lifetime due to the scattering of quasiparticles off of vortices. We compare the results with the experimental measurements on high-Tc cuprates and organic superconductors. © 2000 Elsevier Science B.V. All rights reserved.
