Low Dose, Robert Katz, Francis A. Cucinotta

Robert Katz Publications

Low doses of radiation are frequently inferred to mean doses of the order of 10-100 mGy, regardless of the end point or the nature of the irradiation, as if the energy were deposited uniformly through all targets. Yet, the fluence in a charged particle beam at which there is an average of 1 charged particle transit per target leaves 37% of the targets untouched. At an average of 3 transits per target, 5% of the targets experience no particle transits. Only at an average of 5 transits per target do 99% of the targets achieve one or more transits. One …

Inhibition Of Chloroplast Dna Recombination And Repair By Dominant Negative Mutants Of Escherichia Coli Reca, Heriberto D. Cerutti, Anita M. Johnson, John E. Boynton, Nicholas W. Gillham

Center for Plant Science Innovation: Faculty Publications

Escherichia coli RecA, suggest that the plastid recombination system is related to its eubacterial counterpart. Therefore, we examined whether dominant negative mutants of the E. coli RecA protein can interfere with the activity of their putative homolog in the chloroplast of the unicellular green alga Chlamydomonas reinhardtii. Transformants expressing these mutant RecA proteins showed reduced survival rates when exposed to DNA-damaging agents, deficient repair of chloroplast DNA, and diminished plastid DNA recombination. These results strongly support the existence of a RecA-mediated recombination system in chloroplasts. We also found that the wild-type E. coli RecA protein enhances the frequency of …

Pathways Through Adolescence: An Overview, Lisa J. Crockett, Ann C. Crouter

Department of Psychology: Faculty Publications

Given the connection between adolescent behavior and future well-being, it is important to understand the choices that adolescents make and how patterns of behavior evolve and are maintained during this period. The premise of this volume is that we can describe the behavior patterns young people develop in adolescence, and piece together the decisions that shape their paths through adolescence and into adulthood. Moreover, we can begin to identify the dynamic processes that affect adolescents7 life choices, the emergence of behavior patterns, and the development of lifestyles. This volume seeks to address three questions. How can developmental pathways in adolescence …

Estimation Of Variances Due To Direct And Maternal Effects For Growth Traits Of Nelore Cattle, J. P. Eler, L. Dale Van Vleck, J. B. S. Ferraz, R. B. Lobo

Department of Animal Science: Faculty Publications

Estimates of (co)variance components and genetic parameters were obtained for birth, 205-d, and 365-d weight for Nelore cattle in Brazil, using single and multiple-trait animal models. Data were from the Brazilian Zebu Breeders Association (ABCZ). Records of 27,549 calves sired by 587 bulls and raised on pasture in 57 herds were analyzed by restricted maximum likelihood fitting an animal model including direct and maternal genetic and permanent environmental effects. Single and multiple- trait analyses were carried out. Heritability estimates for direct effects were lower than previous values reported for the Nelore breed. The estimates for maternal genetic effects showed that …

Electrocrystallization Of Strongly Adherent Brushite Coatings On Prosthetic Alloys (Continuation), Jody G. Redepenning

Department of Chemistry: Faculty Publications

An electrolytic method for providing bone-emulating, phosphate coatings on prosthetic appliances. Such coatings serve to enhance bone furation after implantation of the appliances. The method of the invention is an electrolysis process wherein the appliance to be coated is immersed in a phosphate-containing electrolyte to serve as the cathode of the electrolysis process. When current is appIied to the electrolysis cell, the electrolyte solution, which includes calcium ions and dihydrogen phosphate ions, is caused to rapidly increase in (localized) pH proximate the cathode element. The localized pH increase creates a supersaturated local condition causing less soluble calcium phosphate salts to …

Research On Plant Disease And Pest Management Is Essential To Sustainable Agriculture, R. James Cook, Clifford J. Gabriel, Arthur Kelman, Sue Tolin, Anne K. Vidaver

Department of Plant Pathology: Faculty Publications

In the United States, a country with food in great abundance, it is difficult to realize that, were it not for the current level of plant disease and pest management, most human resources would be needed to obtain enough food and other plant and animal products merely to survive. Instead, there are surpluses, markets for many agricultural products are depressed, and funds available for research on plant disease and pest management-and for agricultural research generally-have plateaued or are declining. Why does the United States need more research on plant disease and pest management? Because the health and productivity of the …

A Candidate Genetic Risk Factor For Vascular Disease: A Common Mutation In Methylenetetrahydrofolate Reductase, P. Frosst, H. J. Blom, R. Milos, P. Goyette, Christal A. Sheppard, R. G. Matthews, G. J.H. Boers, M. Den Heijer, L. A.J. Kluijtmans, L. P. Van Den Heuvel, Rima Rozen

Nebraska College of Law: Faculty Publications

Hyperhomocysteinaemia has been identified as a risk factor for cerebrovascular, peripheral vascular, and coronary heart disease. Elevated levels of plasma homocysteine can result from genetic or nutrient-related disturbances in the trans-sulphuration or re-methylation pathways for homocysteine metabolism. 5,10-Methylenetetrahydrofolate reductase (MTHFR) catalyzes the reduction of 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate, the predominant circulatory form of folate and carbon donor for the re-methylation of homocysteine to methionine. Reduced MTHFR activity with a thermolabile enzyme has been reported in patients with coronary and peripheral artery diseases. We have identified a common mutation in MTHFR which alters a highly-conserved amino acid; the substitution occurs at a …

Tumor Necrosis Factor Alpha-Induced Apoptosis In Human Neuronal Cells: Protection By The Antioxidant N-Acetylcysteine And The Genes Bcl-2 And Crma, Angela K. Talley, Stephen Dewhurst, Seth W. Perry, Sheila C. Dollard, Suryaram Gummuluru, Steven M. Fine, Deborah New, Leon Epstein, Howard Gendelman, Harris A. Gelbard

Nebraska Center for Virology: Faculty Publications

Tumor necrosis factor alpha (TNF-α) is a candidate human immunodeficiency virus type 1-induced neurotoxin that contributes to the pathogenesis of AIDS dementia complex. We report here on the effects of exogenous TNF-α on SK-N-MC human neuroblastoma cells differentiated to a neuronal phenotype with retinoic acid. TNF-α caused a dose-dependent loss of viability and a corresponding increase in apoptosis in differentiated SK-N-MC cells but not in undifferentiated cultures. Importantly, intracellular signalling via TNF receptors, as measured by activation of the transcription factor NF-kB, was unaltered by retinoic acid treatment. Finally, overexpression of bcl-2 or crmA conferred resistance to apoptosis mediated by …

Heterozygosity Mapping Of Partially Congenic Lines: Mapping Of A Semidominant Neurological Mutation, Wheels ( Whl), On Mouse Chromosome 4, Patrick M. Nolan, Patricia J. Sollars, Barbara A. Bohne, Warren J. Ewens, Gary E. Pickard, Maja Bucan

School of Veterinary and Biomedical Sciences: Faculty Publications

We identified a semidominant, chemically induced, mouse use mutation with a complex array of abnormal behaviors including bidirectional circling and hyperactivity, abnormal circadian rhythmicity and abnormal responses to light. In this report, we genetically and phenotypically characterized the circling/ waltzing component of the abnormal behavior. We mapped the locus controlling this trait by heterozygosity mapping of partially congenic lines carrying the mutagenized chromosome outcrossed to different inbred strains for three generations. Analysis of 68 PCR-based markers in 13 affected individuals indicated that the mutant locus, named Wheels (Whl), resides in the subcentromeric portion of mouse chromosome 4. The …

Studies Directed Toward Enantioselective Catalysis, Brian E. Jones

Open Access Master's Theses (through 2010)

Many organic molecules of modest size and complexity have chirality.That is, these molecules can exist in more than one stereoisomeric form.There is a strong desire to synthesize chiral compounds that exist in the form of a single stereoisomer.The method of synthesizing chiral compounds that was studied in our research employed a less than stoichiometric amount of chiral catalyst to both catalyze and control the stereochemical outcome of the reactions attempted.

A new chiral ligand was developed to be used as part of the chiral catalyst.This new ligand was used in the enantioselective Diels-Alder cycloaddition reaction and the enantioselective allylation reaction …

Heterogeneity Of Variance By Sire Breed, Sex, And Dam Breed In 200- And 365-Day Weights Of Beef Cattle From A Top Cross Experiment, F. A. Rodriguez-Almeida, L. Dale Van Vleck, Larry V. Cundiff, Stephen D. Kachman

Department of Animal Science: Faculty Publications

The nature of the heterogeneity of variance for 200- and 365-d weights by sex, sire breed, and dam breed subclasses was studied. Data consisted of records for weaning f n = 7,829) and yearling (n = 7,367) weights of progeny from 673 and 672 sires, respectively, from 22 breeds that have been evaluated in the Germ Plasm Evaluation Program at the U.S. Meat Animal Research Center, Clay Center, NE. Sires were mated to Hereford and Angus cows. Each trait was analyzed separately. Three studies were undertaken separately to investigate heterogeneity due to the different factors (i.e, sire breed, sex, or …

Prediction Of Genetic Values Of Sires For Growth Traits Of Crossbred Cattle Using A Multivariate Animal Model With Heterogeneous Variances, R. Nunez-Dominguez, L. Dale Van Vleck, Larry V. Cundiff

Department of Animal Science: Faculty Publications

The purpose of this study was to evaluate the effect of adjusting for heterogeneous variances across breed groups on prediction of breeding values (PBV) of selected sires and on breed of sire effects. Data on weights at birth (BWT), 200 d (WW), and 365 d (YW) of purebred and crossbred calves from matings of Angus (A), Hereford (H), Polled Hereford, Charolais, Shorthorn, Simmental, Limousin, Maine-Anjou, Chianina, Gelbvieh, Tarentaise, and Salers bulls to A and H cows were used. Calf performance in H and A dams was treated as a different trait. Models compared included fixed birth year, cow age, and …

Dynamics Of Wildlife Damage Management, Bobby R. Acord

Great Plains Wildlife Damage Control Workshop Proceedings

Wildlife damage management is a dynamic profession. Our focus has shifted from dealing with primarily agricultural interests. In addition to agricultural issues, we now deal with endangered species protection, human health and safety, and wildlife damage management issues in the urban environment. The dynamics of wildlife damage management are influenced by the changing needs of society, professionalism among our ranks, and the political process. Professionalism and meeting the needs of the public continue to be the most important part of the dynamics of wildlife damage management.

Effective Repellency Concentration Of Bird Shield Repellent(Tm) With Methyl Anthranilate To Exclude Ducks And Geese From Water Impoundments, Leonard R. Askham

Great Plains Wildlife Damage Control Workshop Proceedings

Laboratory studies were conducted to establish the effective repellency concentration (EC_R) of Bird Shield Repellent(^TM) on mallard ducks (Anas platyrhynchos) and domestic geese for fresh water impoundments. Six concentrations of the repellent compound, ranging from 90 ppm to 2,890 ppm, were placed in small ponds in 2 aviaries and bird behavior monitored for 7 days. Concentrations <360 ppm did not limit either of the test species' activities (drinking or bathing) in the impoundments. Concentration >725 ppm precluded most activity after an initial exposure. Dissolved oxygen tended to decrease after an initial rise and pH increased slightly. Impoundments became discolored with higher concentrations of the repellents' methyl anthranilate precipitates in 24 hr.

Biodiversity And Wildlife Damage Management, Ronald G. Eckstein, Robert C. Willging

Great Plains Wildlife Damage Control Workshop Proceedings

The concept of managing natural resources to maintain and restore biodiversity has received increased emphasis from resource managers in recent years. Many state and federal land management agencies have incorporated biodiversity concepts into management plans and programs. Active management of both wildlife habitats and populations must increase as natural systems are simplified and fragmented by human activities. Wildlife damage management programs can be compatible with ecosystem management and maintenance of biodiversity. Species that are widespread but rare and, in particular, species with small and isolated populations remain at risk from environmental and genetic changes, competition, parasitism, and predation. There are …

Human Health Concerns In The Practice Of Wildlife Damage Management, John R. Fischer

Great Plains Wildlife Damage Control Workshop Proceedings

This paper describes diseases that are transmissible from animals to human beings. In many cases, the diseases are contracted by direct contact with the animals. However, several of the diseases are associated with vectors rather than with direct animal contact. Wildlife damage control agents or other wildlife professionals often cannot avoid situations that put them at risk. However, disease may be prevented by knowledge of the risk, and by following simple procedures to minimize risk. Risk may be minimized in many cases with knowledge of transmission modes, endemic areas, and specific preventative measures such as avoidance of known sources of …
