Dynamic Regulation Of Adipose Tissue Metabolism In The Domestic Broiler Chicken – An Alternative Model For Studies Of Human Obesity, Bo Ji, Joelle Dupont, Jean Simon, Sue Lamont, Arnold M. Saxton, Brynn H. Voy 2012 University of Tennessee - Knoxville

Dynamic Regulation Of Adipose Tissue Metabolism In The Domestic Broiler Chicken – An Alternative Model For Studies Of Human Obesity, Bo Ji, Joelle Dupont, Jean Simon, Sue Lamont, Arnold M. Saxton, Brynn H. Voy

Animal Science Publications and Other Works

Background

The domestic chicken is an attractive, but underutilized, animal model for studies of adipose tissue biology, metabolism and obesity: 1.) like humans, chickens rely on liver rather than adipose tissue for the majority of de novo lipogenesis; 2.) quantitative trait loci (QTLs) linked to fatness in chickens contain genes implicated in human susceptibility to obesity and diabetes; 3.) chickens are naturally hyperglycemic and insulin resistant; and 4.) a broad selection of genetic models exhibiting a range of fatness are available. To date, however, little is known about regulation of adipose metabolism in this model organism.

Virginia Shellfish Aquaculture Situation And Outlook Report : Results Of The 2011 Virginia Shellfish Aquaculture Crop Reporting Survey, Thomas J. Murray, Karen Hudson 2012 Virginia Institute of Marine Science

Virginia Shellfish Aquaculture Situation And Outlook Report : Results Of The 2011 Virginia Shellfish Aquaculture Crop Reporting Survey, Thomas J. Murray, Karen Hudson

Reports

The shellfish aquaculture industry in Virginia continues to grow, adding significant value to the state’s seafood marketplace. Today, watermen continue to harvest both hard clams and oysters from the state’s public resources, albeit at diminished rates. At the same time, Virginia’s watermen-farmers are providing growing quantities of additional quality shellfish to consumers. In recent years, folliowing the lead of the hard clam industry, a significant transition to intensive aquaculture of native oysters is underway. The once-extensive oyster planting utilizing wild seed has contracted primarily as a result of endemic oyster diseases and increasing wildlife predation of seed ...

Physiology and Medical Physics Articles

Cannabis use confers a two-fold increase in risk for psychosis, with adolescent use conferring an even greater risk. A high-low activity polymorphism in catechol-O-methyltransferase (COMT), a gene encoding the COMT enzyme involved in dopamine clearance in the brain, may interact with adolescent cannabis exposure to increase risk for schizophrenia. The impact of such an interaction on central neurotransmitter pathways implicated in schizophrenia is unknown. Male mice with knockout of the COMT gene were treated chronically with delta-9-tetrahydrocannabinol (THC) during adolescence (postnatal day 32-52). We measured the size and density of GABAergic cells and the protein expression of cannabinoid receptor 1 ...

Investigating The Role Of An Understudied North Atlantic Right Whale Habitat: Right Whale Movement, Ecology, And Distribution In Jeffreys Ledge, Kathryn Longley 2012 University of Massachusetts Boston

Investigating The Role Of An Understudied North Atlantic Right Whale Habitat: Right Whale Movement, Ecology, And Distribution In Jeffreys Ledge, Kathryn Longley

Graduate Masters Theses

The critically endangered North Atlantic right whale (Eubalaena glacialis) consistently visits five major habitats throughout the year; however, they are known to visit additional habitats. This project examines the role of Jeffreys Ledge as an additional habitat of importance for this species by investigating three aspects of its distribution and ecology. I first addressed the relationship of Jeffreys Ledge to a known significant right whale feeding ground, Cape Cod Bay, by quantifying the movement of right whales between the two habitats and comparing demographic characteristics of right whales seen in these habitats. Secondly, I measured the quality of the zooplankton ...


Colonization Of Zea Mays By The Nitrogen Fixing Bacterium Gluconacetobacter Diazotrophicus, Nikita Eskin 2012 The University of Western Ontario

Colonization Of Zea Mays By The Nitrogen Fixing Bacterium Gluconacetobacter Diazotrophicus, Nikita Eskin

Electronic Thesis and Dissertation Repository

To achieve high yields, corn fields are supplemented with nitrogen fertilizers. Nitrogen fertilizers account for a significant portion of production costs, and are harmful to the environment. Gluconacetobacter diazotrophicus, an endophytic nitrogen-fixing bacterium supplies its natural host sugarcane with a significant amount of nitrogen. This study investigated the colonization of G. diazotrophicus in seven different corn genotypes consisting of sweet and grain corn via three different methods of inoculation: soil drench, root dip, and aseptic inoculation. Sucrose content of the corn genotypes and nitrogenase activity were also analysed. Colonization was confirmed by PCR analysis. G. diazotrophicus colonization was detected using ...


Role Of The Nla6s And Nla28s Histidine Kinases In Fruiting Body Development Of Myxococcus Xanthus, Zaara Sarwar 2012 Syracuse University

Role Of The Nla6s And Nla28s Histidine Kinases In Fruiting Body Development Of Myxococcus Xanthus, Zaara Sarwar

Biology: Dissertations

The complex life cycle of Myxococcus xanthus makes it a model organism for studying multicellular developmental processes in bacteria. In response to adverse environmental conditions, M. xanthus aggregates and forms multicellular structures known as fruiting bodies. Two component signal transduction systems (TCS) are widely used by bacteria to detect and respond to environmental cues by regulating large-scale changes in gene expression. They contain a histidine kinase sensor that detects environmental cues and a response regulator that modulates cellular processes. Two key regulators of the early stages of fruiting body development are the Nla6S/Nla6 and Nla28S/Nla28 TCSs. The response ...


Seasonal Food Habits Of Burrowing Owls (Athene Cunicularia) In Human-Altered Landscapes, Carie Marie Wingert 2012 California Polytechnic State University - San Luis Obispo

Seasonal Food Habits Of Burrowing Owls (Athene Cunicularia) In Human-Altered Landscapes, Carie Marie Wingert

Master's Theses and Project Reports

In 2004, I initiated a year-long study to investigate the food habits of burrowing owls (Athene cunicularia). Burrowing owls have been found in a variety of human-altered landscapes; however, little is known about burrowing owl food habits in urban landscapes. Burrowing owl food habits during the non-breeding season are also largely undocumented, despite increasing concern over the survival of overwintering burrowing owls. Differences in prey consumption between reproductive and non-reproductive owls during the breeding season have not yet been examined. I collected pellets over a 12 month period at four study sites affected by different levels of human alteration in ...


Mapping Plant Biodiversity Hotspots At The County Scale: A New Tool For Establishing Resource Conservation Strategies, Kristie Haydu 2012 Cal Poly State University San Luis Obispo

Mapping Plant Biodiversity Hotspots At The County Scale: A New Tool For Establishing Resource Conservation Strategies, Kristie Haydu

Master's Theses and Project Reports

Myers first identified the world’s 25 biodiversity hotspots and pioneered innovative ideas about the usefulness of biodiversity models for establishing long-term resource conservation strategies at global scales. Since Myers, most of the subsequent studies using hotspot science for biodiversity modeling have used large spatial scales like countries, provinces or states, and other biogeoraphic regions. The California Floristic Province continues to be one of the recognized global biodiversity hotspots. Our study site, San Luis Obispo County is within this hotspot and we created a map of plant biodiversity hotspots at the county scale using GIS technology. We wanted to determine ...


Enhanced Hydrocarbon Biodegradation Using Bioaugmentation With Biowishtm-Aqua Fog, Michael Robert Lehrer 2012 California Polytechnic State University - San Luis Obispo

Enhanced Hydrocarbon Biodegradation Using Bioaugmentation With Biowishtm-Aqua Fog, Michael Robert Lehrer

Master's Theses and Project Reports

This study was done to determine the effectiveness of a commercially available bioaugmentation product, BiOWiSHTM-Aqua FOG, for remediating petroleum-contaminated sandy soil. Biodegradation enhancement by BiOWiSHTM-Aqua FOG was evaluated in laboratory microcosms by directly measuring total petroleum hydrocarbon (TPH) and indirectly using respirometry. Attempts were made to enrich hydrocarbon-degrading bacteria in BiOWiSHTM-Aqua FOG, and the resulting enrichment cultures were screened using respirometry as well. Potential hydrocarbon-degrading bacteria in BiOWiSHTM-Aqua FOG were isolated. Experiments were performed at bench-scale using microcosm bottles containing sand contaminated with either motor oil or No. 2 diesel fuel. The ...


A Proteomic Analysis Of Differentiation In The Mammary Epithelium, Laura Therese Strand 2012 California Polytechnic State University - San Luis Obispo

A Proteomic Analysis Of Differentiation In The Mammary Epithelium, Laura Therese Strand

Master's Theses and Project Reports

While a great deal is known about the changing hormonal environment and the structural development of the mammary gland from pregnancy to lactation, very little is known about the molecular mechanisms governing differentiation of the mammary epithelium into a milk-secreting phenotype. It is important to acknowledge the diversity among the mammary glands of different species in order to better understand applications in human health and the dairy industry. In this study, we examined global protein expression during two states of differentiation in mammary epithelial cells from two species: in vitro proliferating and differentiated MAC-T cells (a bovine immortal cell-line), and ...

Relationship Between Chlorophyll Density And Spad Chlorophyll Meter Reading For Jerusalem Artichoke (Helianthus Tuberosus L.), Ruttanachira Ruttanaprasert, Sanun Jogloy, Nimitr Vorasoot, Thawan Kesmala, Rameshwar S. Kanwar, Carl C. Holbrook, Aran Patanothai

Agricultural and Biosystems Engineering Publications

Chlorophyll is an indicator of crop health and productivity. Measuring chlorophyll is usually done directly and requires significant time and resources. Indirect measurement of chlorophyll density using a handheld portable chlorophyll meter can reduce time. However, this information is very limited for Jerusalem artichoke. The objectives of this study were to examine the stability of chlorophyll density and SPAD chlorophyll meter reading (SCMR) and to evaluate the relationships between chlorophyll density and SCMR for different plant genotypes, at different plant ages and planting dates. Three Jerusalem artichoke varieties were evaluated for chlorophyll density and SCMR in a greenhouse at 13 ...

Agricultural and Biosystems Engineering Publications

Human health has been potentially threatened by cadmium (Cd) contained in sewage irrigation water. Previous studies of Cd transport in soils were mainly conducted using small soil cores with pH values less than 6. The objectives of this study were to determine the parameters of the convection-dispersion equation (CDE) for Cd transport in relatively larger columns with neutral and alkaline soils, and to investigate the parameters' variability with depth. The soil columns were 50 cm in length and 12.5 cm in diameter. Ceramic suction lysimeters were buried at depths of 2.5, 7.5, 17.5, 27.5, and ...

Rickettsia felis is an emerging human pathogen associated primarily with the cat flea Ctenocephalides felis. In this study, we investigated the presence of Rickettsia felis in C. felis from Guatemala and Costa Rica. Ctenocephalides felis were collected directly from dogs and cats, and analyzed by polymerase chain reaction for Rickettsia-specific fragments of 17-kDa protein, OmpA, and citrate synthase genes. Rickettsia DNA was detected in 64% (55 of 86) and 58% (47 of 81) of flea pools in Guatemala and Costa Rica, respectively. Sequencing of gltA fragments identified R. felis genotype URRWXCal2 in samples from both countries, and genotype Rf2125 in ...


Transposition Driven Genomic Heterogeneity In The Drosophila Brain: A Dissertation, Paola N. Perrat 2012 University of Massachusetts Medical School

Transposition Driven Genomic Heterogeneity In The Drosophila Brain: A Dissertation, Paola N. Perrat

GSBS Dissertations and Theses

In the Drosophila brain, memories are processed and stored in two mirrorsymmetrical structures composed of approximately 5,000 neurons called Mushroom Bodies (MB). Depending on their axonal extensions, neurons in the MB can be further classified into three different subgroups: αβ, α’β’ and γ. In addition to the morphological differences between these groups of neurons, there is evidence of functional differences too. For example, it has been previously shown that while neurotransmission from α’β’ neurons is required for consolidation of olfactory memory, output from αβ neurons is required for its later retrieval. To gain insight into the functional ...


Antagonistic Pleiotropy: The Role Of Smurf2 In Cancer And Aging: A Dissertation, Charusheila Ramkumar 2012 University of Massachusetts Medical School

Antagonistic Pleiotropy: The Role Of Smurf2 In Cancer And Aging: A Dissertation, Charusheila Ramkumar

GSBS Dissertations and Theses

In response to telomere shortening, oxidative stress, DNA damage or aberrant activation of oncogenes, normal somatic cells exit the cell cycle and enter an irreversible growth arrest termed senescence. The limited proliferative capacity imposed by senescence on cells impedes the accumulation of mutations necessary for tumorigenesis and prevents proliferation of cells at risk of neoplastic transformation. Opposite to the tumor suppressor function, accumulation of senescent cells in adult organisms is thought to contribute to aging by depleting the renewal capacity of tissues and stem/progenitor cells, and by interfering with tissue homeostasis and functions. The Antagonistic Pleiotropy Theory of senescence ...

Methods: Fifteen national class athletes were assessed for back squat strength, mid-thigh circumference, and mid-thigh skinfold from which total thigh cross-sectional was estimated. A series of One-Way ANOVAs and Pearson Product Moment Correlations were used to ...


Perennial Ryegrass And Tall Fescue Reseeding Intervals After Aminocyclopyrachlor Application, John Workman, Patrick McCullough, F Waltz, Jim Brosnan 2012 University of Tennessee, Knoxville

Perennial Ryegrass And Tall Fescue Reseeding Intervals After Aminocyclopyrachlor Application, John Workman, Patrick Mccullough, F Waltz, Jim Brosnan

Jim Brosnan

Turfgrass managers applying aminocyclopyrachlor for annual and perennial broadleaf weed control in cool-season turfgrasses may want to reseed into treated areas. Field experiments were conducted in Georgia), Tennessee, and Texas to investigate perennial ryegrass (Lolium perenne L.) and tall fescue (Festuca arundinacea Schreb.) reseeding intervals after aminocyclopyrachlor applications. Perennial ryegrass and tall fescue establishment were similar to the non-treated control after treatments of aminocyclopyrachlor and 2,4-dichlorophenoxyacetic acid (2,4-D) + dicamba + methylchlorophenoxypropionic acid (MCPP) at 0, 2, 4, or 6 weeks before seeding. Results demonstrate that no reseeding interval is required after aminocyclopyrachlor treatment. Perennial ryegrass and tall fescue can ...
