Comparative Biology Of Sympatric Red Diamond And Southern Pacific Rattlesnakes In Southern California, Eric Allen Dugan
Loma Linda University Electronic Theses, Dissertations & Projects
I compared the biology of two sympatric rattlesnakes within the context of resource use and niche partitioning. Using radio-telemetry and mark-recapture involving passive integrated transponders (PIT) tags, I studied Red Diamond (Crotalus ruber) and Southern Pacific (C. oreganus helleri) Rattlesnakes in Chino Hills State Park, California, from March 2003 through March 2010. The first of three studies compared the two species in terms of home range size, movements, and mating phenology. Crotalus o. helleri occupied larger home ranges than C. ruber, and exhibited 1.9–2.8-fold greater movement distances (depending on year) than C. ruber. Mating phenology also varied ...
Quantifying The Energetic Contributions Of Desolvation And Π-Electron Density During Translesion Dna Synthesis, 2011 Case Western Reserve University
Quantifying The Energetic Contributions Of Desolvation And Π-Electron Density During Translesion Dna Synthesis, Edward A. Motea, Irene Lee, Anthony J. Berdis
Chemistry Faculty Publications
This report examines the molecular mechanism by which high-fidelity DNA polymerases select nucleotides during the replication of an abasic site, a non-instructional DNA lesion. This was accomplished by synthesizing several unique 5-substituted indolyl 2′-deoxyribose triphosphates and defining their kinetic parameters for incorporation opposite an abasic site to interrogate the contributions of π-electron density and solvation energies. In general, the Kd, app values for hydrophobic non-natural nucleotides are ∼10-fold lower than those measured for isosteric hydrophilic analogs. In addition, kpol values for nucleotides that contain less π-electron densities are slower than isosteric analogs possessing higher degrees of π-electron density. The ...
Comparison Of Various Configurations Of Cdc-Type Traps For The Collection Of Phlebotomus Papatasi Scopoli In Southern Israel, 2011 United States Department of Agriculture-ARS-Center for Medical
Comparison Of Various Configurations Of Cdc-Type Traps For The Collection Of Phlebotomus Papatasi Scopoli In Southern Israel, Daniel L. Kline, Jerome Hogsette, Gunter Muller
Publications from USDA-ARS / UNL Faculty
We conducted two experiments to determine the best CDC-trap configuration for catching male and female Phlebotomus papatasi. First, visual features were evaluated. Standard CDC traps were modified to have black or white catch bags, black or white lids, or no lids and these were tried in different combinations. Significantly more male sand flies were caught by darker traps; significantly more females were captured by traps with either all black or a combination of black and white features. Attraction may be due to dark color or contrast in colors. CDC traps with suction and the following features were also evaluated: no ...
Host-Microbial Symbiosis In The Vertebrate Gastrointestinal Tract And The Lactobacillus Reuteri Paradigm, 2011 University of Nebraska, Lincoln
Host-Microbial Symbiosis In The Vertebrate Gastrointestinal Tract And The Lactobacillus Reuteri Paradigm, Jens Walter, Robert A. Britton, Stefan Roos
Faculty Publications in Food Science and Technology
Vertebrates engage in symbiotic associations with vast and complex microbial communities that colonize their gastrointestinal tracts. Recent advances have provided mechanistic insight into the important contributions of the gut microbiome to vertebrate biology, but questions remain about the evolutionary processes that have shaped symbiotic interactions in the gut and the consequences that arise for both the microbes and the host. Here we discuss the biological principles that underlie microbial symbiosis in the vertebrate gut and the potential of the development of mutualism. We then review phylogenetic and experimental studies on the vertebrate symbiont Lactobacillus reuteri that have provided novel insight ...
Structured Multiple Endosymbiosis Of Bacteria And Archaea In A Ciliate From Marine Sulfidic Sediments: A Survival Mechanism In Low Oxygen, Sulfidic Sediments?, Virginia P. Edgcomb, Edward R. Leadbetter, William A. Bourland, David Beaudoin, Joan M. Bernhard
Marine micro-oxic to sulfidic environments are sites of intensive biogeochemical cycling and elemental sequestration, where prokaryotes are major driving forces mediating carbon, nitrogen, sulfur, phosphorus, and metal cycles, important from both biogeochemical and evolutionary perspectives. Associations between single-celled eukaryotes and bacteria and/or archaea are common in such habitats. Here we describe a ciliate common in the micro-oxic to anoxic, typically sulfidic, sediments of Santa Barbara Basin (CA, USA). The ciliate is 95% similar to Parduzcia orbis (18S rRNA). Transmission electron micrographs reveal clusters of at least three different endobiont types organized within membrane-bound sub-cellular regions. Catalyzed reporter deposition–fluorescent ...

What Is The Potential Of Substituting Legumes For Synthetic Nitrogen In Warm Season Perennial Grasses Used For Stocker Cattle Grazing?, J. Biermacher, John A. Guretzky, Ryan Reuter, Maru Kering, Twain Butler, Job Springer, James Rogers, John Blanton, Joe Bouton
Agronomy & Horticulture -- Faculty Publications
Stocker cattle grazing warm season perennial grasses is an important economic activity in the southern Great Plains. Substantial increases in the price of nitrogen fertilizer is negatively affecting forage producers’ profitability. Two alternative nitrogen management systems that use annual and perennial legumes have been developed for bermudagrass pastures. The goal of the study is to determine if the legumes systems are more profitable than the conventional practice of applying synthetic sources of nitrogen. Enterprise budgeting techniques were employed to compare the economics of the legume systems relative to the common practice. Results of the two-year grazing study show that the ...

Recombinant adeno-associated viruses (rAAVs) that can cross the blood-brain-barrier and achieve efficient and stable transvascular gene transfer to the central nervous system (CNS) hold significant promise for treating CNS disorders. However, following intravascular delivery, these vectors also target liver, heart, skeletal muscle, and other tissues, which may cause untoward effects. To circumvent this, we used tissue-specific, endogenous microRNAs (miRNAs) to repress rAAV expression outside the CNS, by engineering perfectly complementary miRNA-binding sites into the rAAV9 genome. This approach allowed simultaneous multi-tissue regulation and CNS-directed stable transgene expression without detectably perturbing the endogenous miRNA pathway. Regulation of rAAV expression by miRNA ...
The Relationship Between 11-Ketotestosterone, Cortisol, And Testosterone And Condition Index For Poecilia Reticulata, 2011 California Polytechnic State University - San Luis Obispo
The Relationship Between 11-Ketotestosterone, Cortisol, And Testosterone And Condition Index For Poecilia Reticulata, Shelly Gupta, Brandy G. Kalbach
The guppy, Poecilia reticulata, is a common study organism for behavioral and other ecological experiments (Houde, 1997). As far as we know, no previous data have been compiled regarding hormones and condition index of guppies. In this experiment we examined the relationship between circulating levels of three hormones (testosterone, 11-ketotestosterone and cortisol) and condition index in males and also made comparisons among the hormone levels, for three guppy sites from the northern range of Trinidad – Aripo River, Marianne River and Small Crayfish River. Hormone samples were obtained using non-invasive water borne techniques and quantified by our collaborator. The condition index ...
Contributions Of Fungi To Carbon Flow And Nutrient Cycling From Standing Dead Typha Angustifolia Leaf Litter In A Temperate Freshwater Marsh, 2011 University of Southern Mississippi
Contributions Of Fungi To Carbon Flow And Nutrient Cycling From Standing Dead Typha Angustifolia Leaf Litter In A Temperate Freshwater Marsh, Kevin A. Kuehn, Brian M. Ohsowski, Steven N. Francoeur, R.K. Neely
Standing dead plant litter often constitutes a large fraction of the detritus in many freshwater marshes and lake littoral habitats. Despite this evidence, microbial decay processes in standing litter and its contribution to wetland carbon and nutrient cycling have rarely been quantified. We examined the contribution of fungi to carbon flow and nutrient cycling from Typha angustifolia during senescence and standing litter decomposition. Naturally standing Typha leaves were collected in August and then periodically over 1 yr. We quantified losses in leaf carbon (C), fungal biomass, and fungal production rates and constructed a partial budget estimating C flow into fungal ...

Estimating Relative Abundance Of Young-Of-Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay (Spring 2010), Troy D. Tuckey, Mary C. Fabrizio
The Atlantic States Marine Fisheries Commission (ASMFC) adopted the Interstate Fishery Management Plan (FMP) for the American eel in November 1999. The FMP focuses on increasing coastal states’ efforts to collect American eel data through both fishery-dependent and fishery-independent studies. Consequently, member jurisdictions agreed to implement an annual survey for young-of-year (YOY) American eels. The survey is intended to “…characterize trends in annual recruitment of the YOY eels over time [to produce a] qualitative appraisal of the annual recruitment of American eel to the U.S. Atlantic Coast” (ASMFC 2000). The development of these surveys began in 2000 with full ...
Differential Levels Of Glutamate Dehydrogenase 1 (Glud1) In Balb/C And C57bl/6 Mice And The Effects Of Overexpression Of The Glud1 Gene On Glutamate Release In Striatum, Kevin N. Hascup, Xiaodong Bao, Erin R. Hascup, Dongwei Hui, Wenhao Xu, Francois Pomerleau, Peter Huettl, Mary L. Michaelis, Elias K. Michaelis, Greg A. Gerhardt
Neuroscience Faculty Publications
We have previously shown that overexpression of the Glud1 (glutamate dehydrogenase 1) gene in neurons of C57BL/6 mice results in increased depolarization-induced glutamate release that eventually leads to selective neuronal injury and cell loss by 12 months of age. However, it is known that isogenic lines of Tg (transgenic) mice produced through back-crossing with one strain may differ in their phenotypic characteristics from those produced using another inbred mouse strain. Therefore, we decided to introduce the Glud1 transgene into the Balb/c strain that has endogenously lower levels of GLUD1 (glutamate dehydrogenase 1) enzyme activity in the brain as ...

Electrostatic Spraying Of Antioxidants On The Oxidative Quality Of Ground Eef, 2011 Sunchon National University
Electrostatic Spraying Of Antioxidants On The Oxidative Quality Of Ground Eef, K. C. Nam, K. S. Seo, C. Jo, Dong U. Ahn
Animal Science Publications
To prevent oxidative quality changes, a few selected antioxidants, ascorbic acid, or an ascorbic acid plus α-tocopherol combination were electrostatically sprayed on the surface of ground beef patties. Color, metmyoglobin, oxidation-reduction potential, lipid oxidation, and volatiles of the samples were determined during the 8 d of aerobic storage. Spraying of ascorbic acid at 500 mg/kg was the most effective in controlling discoloration of ground beef. Spraying of ascorbic acid at 500 mg/kg was also effective in reducing 2-thiobarbituric acid-reactive substances and volatile aldehydes such as hexanal and heptanal related to lipid oxidation. Spraying of phenolic antioxidants such as ...
Limited Transplantation Of Antigen-Expressing Hematopoietic Stem Cells Induces Long-Lasting Cytotoxic T Cell Responses, 2011 Old Dominion University
Limited Transplantation Of Antigen-Expressing Hematopoietic Stem Cells Induces Long-Lasting Cytotoxic T Cell Responses, Warren L. Denning, Jun Xu, Siqi Guo, Christopher A. Klug, Zdenek Hel
Harnessing the ability of cytotoxic T lymphocytes (CTLs) to recognize and eradicate tumor or pathogen-infected cells is a critical goal of modern immune-based therapies. Although multiple immunization strategies efficiently induce high levels of antigen-specific CTLs, the initial increase is typically followed by a rapid contraction phase resulting in a sharp decline in the frequency of functional CTLs. We describe a novel approach to immunotherapy based on a transplantation of low numbers of antigen-expressing hematopoietic stem cells (HSCs) following nonmyeloablative or partially myeloablative conditioning. Continuous antigen presentation by a limited number of differentiated transgenic hematopoietic cells results in an induction and ...
