Assessing The ‘Whole Animal’: A Free Choice Profiling Approach, Françoise Wemelsfelder, Tony E.A. Hunter, Michael T. Mendl, Alistair B. Lawrence

Sentience Collection

The qualitative assessment of animal behaviour summarizes the different aspects of an animal’s dynamic style of interaction with the environment, using descriptors such as ‘confident’, ‘nervous’, ‘calm’ or ‘excitable’. Scientists frequently use such terms in studies of animal personality and temperament, but, wary of anthropomorphism, are reluctant to do so in studies of animal welfare. We hypothesize that qualitative behaviour assessment, in describing behaviour as an expressive process, may have a stronger observational foundation than is currently recognized, and may be of use as an integrative welfare assessment tool. To test this hypothesis, we investigated the inter- and intraobserver reliability …

Synaptic Heterogeneity And Stimulus-Induced Modulation Of Depression In Central Synapses, John D. Hunter, John Milton

WM Keck Science Faculty Papers

Short-term plasticity is a pervasive feature of synapses. Synapses exhibit many forms of plasticity operating over a range of time scales. We develop an optimization method that allows rapid characterization of synapses with multiple time scales of facilitation and depression. Investigation of paired neurons that are postsynaptic to the same identified interneuron in the buccal ganglion of Aplysia reveals that the responses of the two neurons differ in the magnitude of synaptic depression. Also, for single neurons, prolonged stimulation of the presynaptic neuron causes stimulus-induced increases in the early phase of synaptic depression. These observations can be described by a …

Vo2max Comparison Between Seated And Standing Ergometry, Andrew Bosak

Masters Theses & Specialist Projects

Maximum oxygen consumption (VC^max) represents the highest rate at which oxygen can be consumed and utilized to produce energy sustaining aerobic activity. V02max is regarded as the gold standard for assessing aerobic fitness and is essential for prescribing appropriate exercise intensities. Therefore, accurate determination of VC>2max is vital. Usually, VC>2max is obtained when an individual reaches volitional exhaustion during a Graded Exercise Test (GXT). Previous studies show V02max during standing cycle ergometry protocols and treadmill protocols to be similar, while seated cycle ergometry V02tnax values are lower. Conversely, other studies show seated and standing cycle ergometry V02max to …

Molecular Characterization Of Citrus Tristeza Virus Isolates In Commercial Citrus Grown In Belize, Harry Sabal

Masters Theses & Specialist Projects

Isolates of Citrus Tristeza Virus (CTV) in Belize may be causing inverse stem pitting, stunting, and slow decline on sweet and sour orange rootstock combination on field trees. One isolate on Cleopatra mandarin rootstock expressed no field symptoms but may be a possible source of a detrimental isolate to more susceptible citrus rootstock combinations. Field plants and field source inoculated indicator plants were used in this study. The first objective was to determine whether field trees of sweet Valencia orange trees that expressed symptoms of CTV would test positive to a polyclonal (mild and severe symptoms) and a monoclonal (severe …

Transduction By Phi Bb-1, A Bacteriophage Of Borrelia Burgdorferi, Christian H. Eggers, Betsy J. Kimmel, James L. Bono, Abdallah F. Elias, Patricia Rosa, D. Scott Samuels

Biological Sciences Faculty Publications

We previously described a bacteriophage of the Lyme disease agent Borrelia burgdorferi designated phi BB-1. This phage packages the host complement of the 32-kb circular plasmids (cp32s), a group of homologous molecules found throughout the genus Borrelia. To demonstrate the ability of phi BB-1 to package and transduce DNA, a kanamycin resistance cassette was inserted into a cloned fragment of phage DNA, and the resulting construct was transformed into B. burgdorferi CA-11.2A cells. The kan cassette recombined into a resident cp32 and was stably maintained. The cp32 containing the kan cassette was packaged by phi BB-1 released from this B. …

Restoring Enriched Grasslands: Effects Of Mowing On Species Richness, Productivity, And Nitrogen Retention, John L. Maron, Robert L. Jefferies

Biological Sciences Faculty Publications

Species-rich grasslands that become enriched with nitrogen often suffer decreases in species richness, increases in plant biomass, and invasion by weedy exotic species. Suitable techniques to restore enriched grasslands and reestablish native communities are increasingly needed. Here we report results of a 5-yr experiment in enriched coastal prairie grasslands (Bodega Marine Reserve, Bodega Bay, California, USA), to determine the combined effects of mowing and biomass removal on total soil nitrogen, net rates of mineralization, nitrogen retention, and species richness and biomass. We mowed and removed plant biomass from plots in areas where the N-fixing shrub, bush lupine (Lupinus arboreus …

Disordered Eating And Its Psychosocial Correlates Among Hispanic Adolescent Females, Annette Santiago

All-Inclusive List of Electronic Theses and Dissertations

This study investigated the incidence of disordered eating and its relationship with acculturation, depression, and body dissatisfaction among Hispanic adolescent females. One hundred and five students enrolled at two midwestem high schools completed a Student Demographic Questionnaire, the Bidimensional Acculturation Scale for Hispanics (Marin & Gamba, 1996), the Beck Depression Inventory (Beck, Steer, & Brown, 1996), the Body Dissatisfaction Subscale of the Eating Disorder Inventory (Gamer, Olmstead, & Polivy, 1983), and the Eating Attitudes Test (Gamer, Olmstead, Bohr, & Garfinkel, 1982). Two null hypotheses were examined. The first investigated the relationship among acculturation, depression, body dissatisfaction, and disordered eating utilizing …

Development And Characterization Of Monoclonal Antibodies Directed Against Yaba-Like Disease Virus, Scott Haller

Masters Theses

The hybridoma technique has been used for the production of monoclonal antibodies (mAb) directed against yaba-like disease virus (YLDV). Spleen cells, obtained from female BALB/c mice immunized with YLDV, were fused with P3x63.Ag8.653 myeloma cells and hybrids were selected. Hybridoma clones were screened for production of anti-YLDV antibodies by Indirect Immunofluorescence (IF) microscopy. Positive hybridoma clones were recloned via limiting dilution and characterized. A single clone (H12) has been selected that specifically reacted with YLDV infected cells and not uninfected cells. Immunodiffusion technique determined H12 monoclonal antibody as an IgG1 isoptype immunoglobulin. H12 antibodies recognized a late YLDV protein, and …

Effects Of Liposome-Encapsulated Tnf-Alpha And Radiation Against Colon Cancer, Dong Won Kim

Loma Linda University Electronic Theses, Dissertations & Projects

Previous studies have shown that tumor necrosis factor-α (TNF-α) can augment the antitumor effects of radiation, inhibiting tumor progression to a greater extent than either modality alone. However, nonspecific toxicities associated with TNF-α have limited its use as an adjuvant. This limitation is potentially resolved with the encapsulation of TNF-α in sterically stabilized, PEGylated liposomes (STEALTH®). Thus, the overall hypothesis of the research was that the combination of radiation with STEALTH® liposome encapsulated TNF-α (SL-TNF-α) will have greater efficacy and fewer dose-limiting side effects in the LS174T human colorectal tumor xenograft model compared to the combination of free TNF-α and …

A Novel Strategy Utilizing Co-Expression Of Murine Il-12 And Antisense Tgf-Pl Against H238 Tumor Formation, Craig A. Seheult

Loma Linda University Electronic Theses, Dissertations & Projects

Cytokines have a profound effect on immune modulation, thus playing a significant role in cancer gene therapy. A variety of human carcinomas secrete transforming growth factor-beta (TGF-β), a cytokine with potent immunosuppressive properties. Suppressing TGF-β could be a key to successfully combating malignancies, such as gliomas, mammary, and colon cancers, that over-express TGF-β. Conversely, interleukin-12 (IL-12) is a potent immunostimulatory cytokine capable of regulating T and NK cell-mediated cytotoxic responses (Trinchieri, 1994) during an anti-tumor response. Activation of the immune system with such immunostimulatory cytokines renders it inert to the suppressive effects of TGF-β. To better understand these processes our …

Fundamental Dietary Patterns And Their Correlates Among Us Whites, Marilyn Tseng, Robert F. Devellis

Kinesiology and Public Health

A social history of eating habits in the United States (1) suggests that there are 2 fundamental US dietary patterns. The first, characterized by beef or pork, while flour bread, and potato consumption, is grounded in British culinary heritage. The second, characterized by fruits and vegetables consumed as "protective" foods, that is, to avoid illness, is a result of the development of nutrition science, the growth of good and advertising industries, and efforts of World War 1 food conservation programs. To confirm the occurrence of these 2 dietary patterns and their sociodemographic and lifestyle correlates, we used principal components analysis …

A Heat-Shock-Activated Cdna Encoding Gaga Factor Rescues Some Lethal Mutations In The Drosophila Melanogaster Trithorax-Like Gene, H Granok, B Leibovitch, Sarah C.R. Elgin

Biology Faculty Research

GAGA factor is an important chromosomal protein involved in establishing specific nucleosome arrays and in regulating gene transcription in Drosophila melanogaster. We developed a transgenic system for controlled heat-shock-dependent overexpression of the GAGA factor 519 amino acid isoform (GAGA-519) in vivo. Efficient production of stable protein from these transgenes provided genetic rescue of a hypomorphic Trithorax-like (Trl) lethal allele to adulthood. Nevertheless, supplemental GAGA-519 did not suppress position effect variegation (PEV), a phenomenon commonly used to measure dosage effects of chromosomal proteins, nor did it rescue other lethal alleles of Trl. The results suggest requirements for the additional isoforms of …

Spatial And Temporal Variability In Nest Success Of Snail Kites In Florida : A Meta-Analysis, Victoria J. Dreitz, Robert E. Bennetts, Brian Toland, Wiley M. Kitchens, Michael W. Collopy

Wildlife Biology Faculty Publications

Nesting success of Snail Kites (Rostrhamus sociabilis) in Florida is highly variable among years and locations, and hydrology is the most frequently reported explanatory factor. We conducted a meta-analysis to evaluate the extent of spatial and temporal variability in nesting success, and explicitly tested for the effects of annual minimum water levels. Data were obtained from six independent studies spanning 22 years and 11 wetlands. Our results indicated there was substantial spatial and temporal variability in nest success and that annual minimum water level, either as a categorical or continuous response, was not a significant source of this …

Phylogenetic Relationships Within Cation Transporter Families Of Arabidopsis, Pascal Mäser, Sébastien Thomine, Julian I. Schroeder, John M. Ward, Kendal Hirschi, Heven Sze, Ina N. Talke, Anna Amtmann, Frans J.M. Maathuis, Dale Sanders, Jeff F. Harper, Jason Tchieu, Michael Gribskov, Michael W. Persans, David E. Salt, Sun A. Kim, Mary Lou Guerinot

Dartmouth Scholarship

Uptake and translocation of cationic nutrients play essential roles in physiological processes including plant growth, nutrition, signal transduction, and development. Approximately 5% of the Arabidopsis genome appears to encode membrane transport proteins. These proteins are classified in 46 unique families containing approximately 880 members. In addition, several hundred putative transporters have not yet been assigned to families. In this paper, we have analyzed the phylogenetic relationships of over 150 cation transport proteins. This analysis has focused on cation transporter gene families for which initial characterizations have been achieved for individual members, including potassium transporters and channels, sodium transporters, calcium antiporters, …

The Detection Of Morphological Variation Across Time In Two Roan Mountain Endemics: Geum Radiatum And Houstonia Montana., Dalenia Medford

Electronic Theses and Dissertations

Morphological variation between geographically distant populations has long been recognized. The primary objective of this study was to test whether nonrandom shifts in morphology have occurred across a 150-year time span in two rare, endangered plant species Geum radiatum and Houstonia montana. During the last century the vegetation on Roan Mountain has undergone numerous environmental pressures that may have produced morphological shifts.

A diverse suite of morphological characters was measured from both species. Characters included vegetative and reproductive structures. Herbarium specimens and direct field measurements were the sources of material used. Results indicated a significant increase in size across …
