Journal Articles: Regenerative Medicine

Abnormal humoral responses toward motor end plate constituents in muscle induce myasthenia gravis (MG). To study the etiology of this disease, and whether it could be induced by host defense molecules, we examined the consequences of interferon (IFN) gamma production within the neuromuscular junction of transgenic mice. The transgenic mice exhibited gradually increasing muscular weakness, flaccid paralysis, and functional disruption of the neuromuscular junction that was reversed after administration of an inhibitor of acetylcholinesterase, features which are strikingly similar to human MG. Furthermore, histological examination revealed infiltration of mononuclear cells and autoantibody deposition at motor end plates. Immunoprecipitation analysis indicated …


Sensitization To Self (Virus) Antigen By In Situ Expression Of Murine Interferon-Gamma., Myung-Shik Lee, Matthias Von Herrath, Hans Reiser, Michael B.A. Oldstone, Nora Sarvetnick Feb 1995

Sensitization To Self (Virus) Antigen By In Situ Expression Of Murine Interferon-Gamma., Myung-Shik Lee, Matthias Von Herrath, Hans Reiser, Michael B.A. Oldstone, Nora Sarvetnick

Journal Articles: Regenerative Medicine

Autoimmune disease results from inflammatory destruction of tissues by aberrant self-reactive lymphocytes. We studied the autoimmune potential of T lymphocytes immunologically ignorant of viral antigens acting as self antigens and whether the host defense molecule IFN-gamma could stimulate these cells to cytotoxic competency. For this purpose, we produced double transgenic mice expressing pancreatic IFN-gamma as well as lymphocytic choriomeningitis virus (LCMV) nucleoprotein (NP) or glycoprotein (GP) antigen. 100% of the NP+/IFN-gamma+ mice became diabetic before 2 mo of age, while none of the NP single transgenic littermates and only 10% of IFN-gamma single transgenic littermates did. Strikingly, NP+/IFN-gamma+ mice spontaneously …

A Novel Translational Regulation Function For The Simian Virus 40 Large-T Antigen Gene., Prithi Rajan, Sathyamagalam Swaminathan, Jiyue Zhu, Charles N. Cole Feb 1995

A Novel Translational Regulation Function For The Simian Virus 40 Large-T Antigen Gene., Prithi Rajan, Sathyamagalam Swaminathan, Jiyue Zhu, Charles N. Cole

Dartmouth Scholarship

Cells use the interferon-induced, double-stranded-RNA-dependent protein kinase PKR as a defense against virus infections. Upon activation, PKR phosphorylates and thereby inactivates the protein synthesis initiation factor eIF-2, resulting in the cessation of protein synthesis. Viruses have evolved various strategies to counteract this cellular defense. In this paper, we show that simian virus 40 (SV40) large-T antigen can antagonize the translational inhibitory effect resulting from the activation of PKR in virus-infected cells. Unlike the situation with other virus-host cell interactions, SV40 large-T antigen does not block the activation of PKR, suggesting that SV40 counteracts the cellular antiviral response mediated by PKR …


Implications Of Native Title Legislation For Fisheries Management And The Fishing Industry In Western Australia, Patricia Summerfield Feb 1995

Implications Of Native Title Legislation For Fisheries Management And The Fishing Industry In Western Australia, Patricia Summerfield

Fisheries management papers

This paper seeks to examine the key issues of both State and Commonwealth native title legislation for the fishing industry and fisheries management in Western Australia. Considerations for Aboriginal involvement in the industry and long-standing as well as recent concessionary arrangements for traditional usage of fish resources are examined. Industry reactions and future plans to accommodate native title in a positive framework are explored.


Avian Life-History Evolution In Relation To Nest Sites, Nest Predation, And Food, Thomas E. Martin Feb 1995

Avian Life-History Evolution In Relation To Nest Sites, Nest Predation, And Food, Thomas E. Martin

Wildlife Biology Faculty Publications

Food limitation is generally thought to underlie much of the variation in life history traits of birds. I examined variation and covariation of life history traits of 123 North American Passeriformes and Piciformes in relation to nest sites, nest predation, and foraging sites to examine the possible roles of these ecological factors in life history evolution of birds. Annual fecundity was strongly inversely related to adult survival, even when phylogenetic effects were controlled. Only a little of the variation in fecundity and survival was related to foraging sites, whereas these traits varied strongly among nest sites. Interspecific differences in nest …


Zinc Metabolism In The Streptozotocin (Stz)-Diabetes, Aizhong Fu Feb 1995

Zinc Metabolism In The Streptozotocin (Stz)-Diabetes, Aizhong Fu

Doctoral Dissertations 1896 - February 2014

Hyperzincuria in diabetics has been regarded as the culprit depleting body zinc stores. Studies were designed to assess rates of 65Zn absorption and retention as a possible compensation mechanism; to assess zinc concentrations and distribution among body compartments, and to assess the kinetics of 65Zn metabolism in STZ-diabetic rats. The rates of 65Zn absorption and retention were not significantly different between STZ-diabetic and control rats. However, STZ-diabetic rats had significantly higher rates of 65Zn absorption (16.88%) and retention (34.36%) when they were "Post-fasted" than when they were "Prior-fasted" (9.04% and 18.68% respectively). These differences were also present in control rats …

Increased Stem Cell Factor Release By Hemangioma-Derived Endothelial Cells, C. J. Meininger, Shannon Brightman, K. A. Kelly, B. R. Zetter Feb 1995

Increased Stem Cell Factor Release By Hemangioma-Derived Endothelial Cells, C. J. Meininger, Shannon Brightman, K. A. Kelly, B. R. Zetter

Biology Faculty Publications

Background: Capillary hemangiomas, the most common tumors in young children, consist of proliferating capillary vessels and endothelial cells. These tumors also contain large numbers of mast cells, compared with the normal surrounding skin or tissue. We have recently shown that stem cell factor (SCF), the gene product of the murine steel locus, can act as a chemoattractant for mast cells. In this study, we investigated whether SCF might be involved in the recruitment and maintenance of mast cells in hemangiomas. Experimental Design: Cultured endothelial cells derived from a murine hemangioma were compared with normal vascular endothelial cells for the ability …


Ruminal Degradation Of Switchgrass, Big Bluestem, And Smooth Bromegrass Leaf Proteins, Daren D. Redfearn, Lowell E. Moser, Steven S. Waller, Terry J. Klopfenstein Feb 1995

Ruminal Degradation Of Switchgrass, Big Bluestem, And Smooth Bromegrass Leaf Proteins, Daren D. Redfearn, Lowell E. Moser, Steven S. Waller, Terry J. Klopfenstein

Department of Agronomy and Horticulture: Faculty Publications

Two in situ protein disappearance experiments were conducted to determine disappearance rates of leaf protein fractions and characterize individual leaf protein fractions that escaped ruminal degradation. Fresh leaf blades of two warm-season grasses, switchgrass (Panicum uirgatum L. 1 and big bluestem (Andropogon gerardii Vitman), and one cool-season grass, smooth bromegrass (Bromus inermis Leyss.), were included in Exp. 1. Only warm season grasses were used in Exp. 2. Leaves were harvested from greenhouse-grown plants, placed in polyester bags, and incubated up to 48 h in situ in three ruminally fistulated steers fed diets of warm season grass hay. …


Quantifying Developmental Morphology Of Perennial Grasses, K. J. Moore, Lowell E. Moser Feb 1995

Quantifying Developmental Morphology Of Perennial Grasses, K. J. Moore, Lowell E. Moser

Department of Agronomy and Horticulture: Faculty Publications

Perennial forage grasses can be viewed as modular organisms. The phytomer is usually considered the basic unit of the grass plant and consists of a leaf blade and sheath, the internode, the node, and the associated axillary bud below the point of sheath attachment. The tiller is a collection of phytomers differentiated from a single apical meristem. The grass plant is a group of tillers that ultimately arise from a single zygote and are of the same genotype. A grass sward is a population of individual plants, often genetically related, but usually of unique genotypes. The developmental morphology of perennial …

Serendip Deborahae N. Gen. And N. Sp. (Eucestoda: Tetraphyllidea: Serendipidae N. Fam.) In Rhinoptera Steindachneri Evermann And Jenkins, 1891 (Chondrichthyes: Myliobatiformes: Myliobatidae) From Southeastern Ecuador, Daniel R. Brooks, Ramiro Barriga

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Cestodes collected in spiral valves of Rhinoptera steindachneri from the southern coast of Ecuador represent an undescribed species of Tetraphyllidea. The new species has bothridia possessing septa but lacking apical suckers. It is diagnosably distinct from all other tetraphyllidean genera by possessing a scolex comprising 4 triangular bothridia that are fused together forming a platelike structure, each of which is subdivided by 2 simple and 1 bifurcating septa radiating from its base and ringed by marginal loculi; therefore, a new genus is proposed for it. By exhibiting some degree of bothridial fusion, testes arranged in 2 layers in the proglottis …


An Improved Method For Chemical Devitellinization Of X-Gal Stained Drosophila Embryos, Amit Singh, Madhuri Kango-Singh, P. Sinha Feb 1995

An Improved Method For Chemical Devitellinization Of X-Gal Stained Drosophila Embryos, Amit Singh, Madhuri Kango-Singh, P. Sinha

Biology Faculty Publications

In Drosophila developmental biological studies, X-gal staining is commonly employed to study the spatio-temporal expression of the lacZ reporter gene in the transformed flies or their embryos. Study of the lacZ pattern in embryos often suffers from the lack of an efficient and high yieldirrg technique for devitellinization of X-gal stained embryos. Devitellinization techniques employed during antibody staining, in situ hybridization or embryonic cuticular preparations generally do not give satisfactory results when used for similar purpose in X-gal stained embryos. This results in the flaky appearance of the blue stain. We present here an improved chemical devitellinization technique which gives …
