Fate Of The Vegetal Yolky Cells In The Direct Developing Frog Eleutherodactylus Coqui, Uma Karadge

Electronic Theses and Dissertations

The Puerto Rican tree frog, Eleutherodactylus coqui, is a striking example of a deviation from the indirect mode of development among amphibians. E. coqui does not have an intermediate tadpole stage. It hatches out directly as a free-living froglet, deriving nutrition from the yolky material attached to its intestine. The innermost of the three germ layers, the endoderm, forms the lining of the gut. In the amphibian model Xenopus laevis, the endoderm originates from the vegetal hemisphere. The cells, which are originally present on the vegetal surface of the embryo, end up forming the definitive gut. They, thus, provide nutrition …

Characterization Of A Type Ii Metallothionein From Helianthus Annuus Using Recombinant Dna Techniques, Sridhar Bhogavalli

ETD Archive

Metallothioneins (MTs) are ubiquitous low molecular weight, cysteine rich proteins with a pronounced affinity for metal ions with d10 configuration such as Cu, Cd and Zn. These heavy metals form metal-thiolate clusters with cysteine side chains. In contrast to the vertebrate forms, knowledge about the properties of members of the plant metallothionein family is still scarce. We describe here a method of isolation and purification of metallothionein from the plant Helianthus annuus, performed by affinity chromatography using glutathione-agarose column. In this study, alignment of gene sequence of the isolated H. annuus metallothionein cDNA with known MTs showed that it belongs …

Mathematical Model Of Ethanol Metabolism In Liver, Parag Pande

ETD Archive

A lumped mathematical model of liver metabolism is presented to analyze the effect of ethanol on metabolic processes of 24 hr fasted rats. The model is developed in two parts. In the first part individual kinetic models for important regulatory steps in the liver metabolic pathways are developed and in second part transport and mass balance equations in the two well mixed domains: tissue and blood, are developed to calculate intermediate metabolite concentrations and fluxes in response to the changes in ethanol and lactate concentrations in the perfusion medium. Part of the model without ethanol metabolism has been validated and …

Studying The Interaction Of Antifreeze Proteins (Type I And Type Iii) With The Phospholipid Monolayers At Air/Water Interface, Suresh Essampally

ETD Archive

Heart transplantation is a successful therapeutic procedure for the patients with end stage heart disease. Various preservative techniques have been developed to increase the shelf life of organs, but still there can be tissue damage during cold storage. One mechanism leading to damage is disruption of cell plasma membranes as they pass through temperature induced phase transitions. The addition of antifreeze protein (AFP) or glycoprotein (AFGP) to storage solutions has been hypothesized to reduce the leakiness of lipid membranes. From studies using liposomes it has been shown that AFPs can prevent leakage through lipid membranes, although the mechanism of interaction …

Performance Characteristics Of An Innovative Wind Power System, David James Kerze

ETD Archive

This project entails a study of a wind energy recovery system that utilizes a unique three-dimensional spiral structure to amplify wind speed and direct it toward pluralities of turbines. The system is comprised of an outer spiral shell, internal support structure, turbines, and mechanisms for positioning the turbines to face the prevailing wind. Computational Fluid Dynamics (CFD) analyses were conducted to determine the wind speed amplification factors as a result of a simulated wind flow around the spiral structure. To ensure accuracy of the results, state of the art CFD techniques were applied using Gambit 2.2.30 and Fluent 6.2.16. Specifically, …

Army Research Needs For Automated Neuropsychological Tests: Monitoring Soldier Health And Performance Status, Karl E. Friedl, Stephen J. Grate, Susan P. Proctor, James W. Ness, Brian J. Lukey, Robert L. Kane

United States Army: Publications

Information on the mental status of soldiers operating at the limits of human tolerance will be vital to their management in future deployments; it may also allow earlier intervention for conditions such as undiagnosed Gulf War illnesses and Parkinson’s Disease. The Army needs a parsimonious set of neuropsychological tests that reliably identify subtle changes for: (1) early detection of individual health and military performance impairments and (2) management of occupational and deployment health risks. Testing must characterize cognitive lapses in healthy individuals faced with relevant operational stressors (i.e., anxiety, information overload, thermal strain, hypoxia, fatigue, head impact, chemical or radiation …

Improved Formulation Of A Recombinant Ricin A-Chain Vaccine Iincreases Its Stability And Effective Antigenicity, John H. Carra, Robert W. Wannemacher, Ralph F. Tammariello, Changhong Y. Lindsey, Richard E. Dinterman, Rowena D. Schokman, Leonard A. Smith

United States Army: Publications

Ricin is a potent toxin associated with bioterrorism for which no vaccine or specific countermeasures are currently available. A stable, non-toxic and immunogenic recombinant ricin A-chain vaccine (RTA 1-33/44-198) has been developed by protein engineering. We identified optimal formulation conditions for this vaccine under which it remained stable and potent in storage for up to 18 months, and resisted multiple rounds of freeze–thawing without stabilizing co-solvents. Reformulation from phosphate buffer to succinate buffer increased adherence of the protein to aluminum hydroxide adjuvant from 15 to 91%, with a concomitant increase of nearly threefold in effective antigenicity in a mouse model. …

An In Vitro Comparative Study On The Reactivation Of Nerve Agent-Inhibited Guinea Pig And Human Acetylcholinesterases By Oximes, Chunyuan Luo, Min Tong, Nageswararao Chilukuri, Karen Brecht, Donald M. Maxwell, Ashima Saxena

United States Army: Publications

The reactivation of nerve agent-inhibited acetylcholinesterase (AChE) by oxime is the most important step in the treatment of nerve agent poisoning. Since the evaluation of nerve agent antidotes cannot be conducted in humans, results from animal experiments are extrapolated to humans. Guinea pig is one of the animal models that is frequently used for conducting nerve agent antidote evaluations. Several investigations have demonstrated that the efficacy of an oxime primarily depends on its ability to reactivate nerve agent-inhibited AChE. If the in Vitro oxime reactivation of nerve agent-inhibited animal AChE is similar to that of human AChE, it is likely …

The Impact Of Experienced Versus Non-Experienced Suggestions On Children’S Recall Of Repeated Events, Martine B. Powell, Kim Roberts, Donald M. Thomson, Stephen J. Ceci

Psychology Faculty Publications

Three experiments were conducted to test the proposition that children’s suggestibility about an occurrence of a repeated event is heightened when an interviewer suggests false details that were experienced in non-target occurrences of the event as opposed to new details that never occurred. In each experiment, children participated in a repeated event during which specific items varied each time (e.g., the children always got a sticker but the theme of the sticker was different in each occurrence). Separate biasing and memory interviews were then conducted. In Experiment 1, the interviewer merely suggested that the false details might have occurred in …

Loathsome Beasts: Images Of Reptiles And Amphibians In Art And Science, Kay Etheridge

Biology Faculty Publications

The mythology and symbolism historically associated with reptiles and amphibians is unequaled by that of any other taxonomic group of animals. Even today, these creatures serve as icons - often indicating magic or evil - in a variety of media. Reptiles and amphibians also differ from other vertebrates (i.e. fish, mammals and birds) in that most have never been valued in Europe as food or for sport. Aside from some limited medicinal uses and the medical concerns related to venomous species, there was little utilitarian value in studying the natural history of reptiles and amphibians. Because of this history and …

Teachers As Reflective Practitioners: Examining Teacher Stories Of Curricular Change In A 4th Grade Classroom, William P. Bintz, Jill Dillard

Reading Horizons: A Journal of Literacy and Language Arts

This article describes findings from a classroom-based action research project conducted by two in-school teachers, a literacy coach and a 4'h grade teacher, implementing a new integrated literacy and social studies curriculum and the changes they made in curricular practices and beliefs over a three-year period of time. A university professor also served as an out-of-school researcher assisting with analyzing data, describing findings, and discussing implications. The project was based on the model of teacher as researcher asking two focused inquiry questions: 1) what can be learned about teaching by taking a reflective practitioner perspective as a way to think …

Temples Of Caesar: The Politics Of Renaissance Georgics Translations, Kimberly Johnson

Quidditas

Between the last years of Elizabeth I’s reign and the regicide of Charles I, three major English translations of Virgil’s middle poem, the Georgics, were published. Each translation appeared at a moment of religio-political crisis in England, a coincidence made more significant by the ambivalent political stance of Virgil’s text, which simultaneously communicates praise for Octavian and suspicion about an imperial program that disenfranchised the agricultural classes, an oversight which Virgil records in the Georgics as impiety. This paper charts the ways in which seemingly innocent translation decisions manage to perform a critical interrogation of monarchal authority, particularly as it …

William Of Auvergne And Popular Demonology, Thomas De Mayo

Quidditas

Theologian and bishop of Paris during St. Louis’ early reign, William of Auvergne (d. 1249) aimed in his life and writings to combat the myriad threats he perceived as facing Christianity. The early thirteenth century saw many potential competitors to official doctrines concerning the natural and supernatural worlds—Arabic philosophy imported into the universities, heretical attacks on the institutional church, and persistent folk beliefs and practices. William attributed these challenges to an underlying demonic conspiracy directed against humankind. This paper examines William’s treatment of popular beliefs on the Wild Hunt, a mysterious congregation of spirits, and related beliefs about female spirits …

A Decade Comparison Of Preterm Motor Performance At Age 4, Mary C. Sullivan, Kathleen Hawes

College of Nursing Faculty Publications

This was a prospective longitudinal study of two cohorts comprised of one full term and three premature infant groups born 10 years apart. Birth cohort, perinatal morbidity, and birth weight effects were investigated at age 4. Cohort 1 (1985–1989) had longer gestation, higher birth weight, and better Apgar scores than Cohort 2 (1996–1999), which had more intraventricular hemorrhage and bronchopulmonary dysplasia. Cohort and perinatal morbidity group, but not birth weight, predicted motor scores. Preterm Cohort 2 children had better oral motor, fine motor, and total motor scores, but lower visual motor integration scores than Cohort 1. Motor problems continue to …
