Numerical Aspects Of Discrete And Continuum Hybrid Models In Cell Biology, J. C. Dallon

Faculty Publications

In this paper we introduce a method of modeling which mixes continuum and discrete variables, and explain two models in cell biology that use this method. The first application deals with wound healing, more specifically the collagen alignment in scar tissue formation and the second models early aggregation in the cellular slime mold Dictyostelium discoideum. We solve these models using numerical techniques similar to the particle-in-cell method which requires that the discrete and continuum variables are interpolated one to the other. The implementational and numerical details are discussed in an informal and practical manner with particular attention given to the …

Survival And Causes Of Mortality Of Relocated And Resident Northern Bobwhites In East Texas, Xiangwen Liu, R. Montague Whiting Jr., Brad S. Mueller, D. Scott Parsons, Donald R. Dietz

Faculty Publications

We estimated survival of 3 groups of northern bobwhites (Colinus virginianus) on a 563-ha intensively managed study area in eastern Texas. During the 3-year study, 155 bobwhites from South Texas and 136 bobwhites from East Texas were captured, radio-marked, and relocated to the study area; 139 bobwhites that were resident on the study area were also captured, radio-marked, and released at the point of capture. There were no differences (P > 0.05) in survival among the 3 groups of bobwhites. However, survival of bobwhites from South Texas were consistently lower than those of the other 2 groups during each year; both …

Survey Of Pathogens In Poultry Litter In The United States, Mac Terzich, Melody J. Pope, Tim E. Cherry, Jessie Hollinger

Faculty Publications

Poultry litter is one of many components resulting from the production of broilers. Understanding poultry litter microbiological composition is very beneficial when attempting to improve the broiler's environmental conditions and searching for the best uses for this valuable industry by-product. The objective of this study was to collect samples of poultry litter throughout the United States and determine the presence of bacteria in the litter. Tests were conducted for total bacteria, Gram negative bacteria, Gram positive bacteria, Staphylococcus, Escherichia coli, and coliforms. Poultry litter samples were taken from 12 different regions throughout the United States and were analyzed …

An Evaluation Of The Presence Of Pathogens On Broilers Raised On Poultry Litter Treatment-Treated Litter, M. J. Pope, T. E. Cherry

Food Plot Use By Juvenile Northern Bobwhites In East Texas, D. Scott Parsons, R. Montague Whiting Jr., Xiangwen Liu, Donald R. Dietz

Faculty Publications

We examined use of spring-summer (i.e., warm-season) food plots by northern bobwhites (Colinus virginianus) with broods using radio telemetry on a 563-ha study area in Trinity County, eastern Texas, where habitat was modified to enhance it for these birds. Bobwhites from South Texas and disjunct areas of East Texas were introduced to supplement a small, resident population. All relocated and most resident bobwhites were fitted with necklace-style transmitters. Bobwhites which produced chicks were intensively radiotracked (≥3 times/day) for ≥4 weeks or until the radio-marked parent was lost. Nine hens moved their broods to food plots within an average of 2.1 …

Tort Liability, Religious Entities, And The Decline Of Constitutional Protection, Scott C. Idleman

Faculty Publications

This article examines the long-term viability of the First Amendment prohibition on the adjudication of legal actions requiring the resolution of religious questions, such as disputes over theological doctrine, scriptural interpretation, or ecclesiastical law. In particular, the article focuses on tort suits against religious institutions and clergy, often stemming from the latter's alleged misconduct towards congregants or children. Part I contends that the bar on certain tort actions is actually an application of a more general prohibition on the adjudication of religious questions and examines the contours of this prohibition and its specific application in the tort context. Part II …

The Cartagena Protocol And Biological Diversity; Biosafe Or Bio-Sorry, Jonathan H. Adler

Faculty Publications

In January 2000, delegates from over 100 nations completed negotiations on an international treaty for the regulation of biotechnology, the Cartagena Protocol on Biosafety. The stated purpose of this protocol is to enhance the protection of biological diversity. Despite its good intentions, there is a mismatch between the protocol's substantive provisions and present threats to biological diversity. The protocol endorses "precautionary" regulation of transboundary shipments of genetically engineered organisms, including crops, so as to reduce the environmental risks that such organisms may pose. The greatest threat to biological diversity is habitat loss, largely driven by the conversion of land for …

Beneficial And Unusual Punishment: An Argument In Support Of Prisoner Participation In Clinical Trials, Sharona Hoffman

Faculty Publications

Currently, approximately 1.8 million people are incarcerated in the United States at any given time. A disproportionately large percentage of the prisoner population has serious illnesses, such as AIDS and tuberculosis. Prisoners most often, however, are barred from participation in clinical trials, even when conventional therapy has failed, and experimental treatment might provide them with their only hope of survival.

Much of the reluctance to include prisoners in biomedical research is based on history. In the past, prisoners have been severely abused and even tortured in medical studies conducted in the Nazi death camps, Japanese prisoner camps, and correctional facilities …

Functional Microanatomy Of The Feather-Bearing Integument: Implications For The Evolution Of Birds And Avian Flight, Dominique G. Homberger, Kumudini N.D.E. Silva

Faculty Publications

A selective regime favoring a streamlining of body contours and surfaces is proposed as having been instrumental in driving the morphological and functional transformations of an unfeathered reptilian integument into a featherbearing avian one. This hypothesis is consistent with a new, structurally and functionally coherent analysis of the microanatomy of the avian feather-bearing integument as a complex, integrated organ system that includes an intricate, hydraulic skeleto-muscular apparatus of the feathers, a dermo-subcutaneous muscle system of the integument, and a subcutaneous hydraulic skeletal system formed by fat bodies. Key elements of the evidence supporting the new hypothesis are (1) the presence …

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

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. …

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

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 …

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 …

Ficht, L. Garry Adams, Sue D. Hagius, Philip H. Elzer, Betsy J. Bricker, Girish K. Kumar, M. Rajasekhar, Srikrishna Isloor, Raj R. Barathur

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 …

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 …

Movement And Territoriality Of Wintering Hermit Thrushes In Southeastern Louisiana, David R. Brown, Philip C. Stouffer, Cheryl M. Strong

Faculty Publications

We describe the spatial organization and social behavior of Hermit Thrushes (Catharus guttatus) wintering in pine plantations and an adjacent hardwood forest in Tangipahoa Parish, Louisiana over three winters. We used point counts (n = 403) to collect data on agonistic behaviors and relative abundance within the study area. We used mist-netting to study site fidelity on four 9-ha plots within and among years. We used radio-telemetry to measure Hermit Thrushes' movements and territoriality (n = 50). We found that Hermit Thrushes saturated suitable patches within the study area. Most Hermit Thrushes actively defended small [mean = 0.55 ± 0.03 …
