An Exploration Of The Wheel-Induced Feeding-Suppression, Stephen Benjamin Peckham Jan 2015

An Exploration Of The Wheel-Induced Feeding-Suppression, Stephen Benjamin Peckham

Theses and Dissertations (Comprehensive)

Anorexia nervosa is an enigmatic human condition typified by food-restriction that is often accompanied by extensive exercise. This has been modeled in rats in the wheel-induced feeding-suppression (WIFS) model. In this model, animals are given access to a running-wheel, which induces a volitional drop in food-consumption. Short periods of wheel access have induced a feeding-suppression which is effectively reversed by chlorpromazine administration (Adams et al., 2009). Recent attempts at replicating Adams et al.’s (2009) feeding-suppression have, however, been unsuccessful (Peckham et al., 2013). These attempts raised questions as to whether or not the existing methodology is most effective at ...


Anthropogenic Noise Alters Bat Activity Levels And Echolocation Calls, Jessie P. Bunkley, Christopher J.W. Mcclure, Nathan J. Kleist, Clinton D. Francis, Jesse R. Barber Jan 2015

Anthropogenic Noise Alters Bat Activity Levels And Echolocation Calls, Jessie P. Bunkley, Christopher J.W. Mcclure, Nathan J. Kleist, Clinton D. Francis, Jesse R. Barber

Jesse R. Barber

Negative impacts from anthropogenic noise are well documented for many wildlife taxa. Investigations of the effects of noise on bats however, have not been conducted outside of the laboratory. Bats that hunt arthropods rely on auditory information to forage. Part of this acoustic information can fall within the spectrum of anthropogenic noise, which can potentially interfere with signal reception and processing. Compressor stations associated with natural gas extraction produce broadband noise 24 hours a day, 365 days a year. With over half a million producing gas wells in the U.S. this infrastructure is a major source of noise pollution ...

Lkb1 Deficient Non-Small Cell Lung Cancer Cells Are Vulnerable To Energy Stress Induced By Atp Depletion, Chao Yang Dec 2014

Lkb1 Deficient Non-Small Cell Lung Cancer Cells Are Vulnerable To Energy Stress Induced By Atp Depletion, Chao Yang

UT GSBS Dissertations and Theses (Open Access)

Lung cancer is the second most frequent cancer in United States, which represents about 13.5% of new cancer cases every year. It accounts for about 27.2% of all cancer related deaths, which is more than the sum of deaths caused by prancretic, breast and colorectal. On average, only about 16% of lung cancer patients survive beyond 5 years. LKB1 is the third most mutated gene in lung cancer. It has been shown that LKB1 is mutated in at least 15% to 30% of NSCLC. Tumor with LKB1 mutation is associated with poor differentiation, high metastasis and worse response ...

STRUCTURAL INVESTIGATIONS OF LIGAND GATED ION CHANNELS

Swarna Ramaswamy, B.S

Advisor: Vasanthi Jayaraman, Ph.D.

Ion channels form an integral part of membrane proteins. In the nervous system including the central and the peripheral nervous system, ligand gated ion channels form a very important part of intercellular communications. They receive chemical signals and convert them to electrical signal, mainly by allowing ion passage across the cell membrane. Ion passage also translates into downstream signaling events. Faithful translation of these signals and transmittance is crucial for several physiological functions, implying that irregular ion channel function could lead to serious consequences ...


Student Mindset Compared To Performance On The Nebraska State Accountability Test, Ann E. Dvorak Dec 2014

Student Mindset Compared To Performance On The Nebraska State Accountability Test, Ann E. Dvorak

Theses, Dissertations, & Student Scholarship: Agricultural Leadership, Education & Communication Department

Carol Dweck’s research on fixed vs. growth mindset has led to many opportunities for educational research. According to Dweck, a person with a fixed mindset believes that his or her qualities related to a certain task are unchangeable while an individual with a growth mindset believes that his or her qualities related to a certain task can be changed and improved (Dweck, 2006). A correlative study was conducted to identify relationships that exist between student mindset and scores from the Nebraska State Accountability Test (NeSA). For this study, students in the 7th, 8th, and 11th grade ...


Variation In Size And Abundance Of Caribbean Spiny Lobster (Panulirus Argus) With Change In Hardbottom Habitat, Amie Lentner, Robert Ellis Nov 2014

Variation In Size And Abundance Of Caribbean Spiny Lobster (Panulirus Argus) With Change In Hardbottom Habitat, Amie Lentner, Robert Ellis

The Owl

The specific characteristics that make a habitat suitable for an organism vary both between species and between life stages within a single species. Hardbottom habitats in Florida Bay are known as nurseries for a number of commercially and ecologically important species. In this study, we focused on the Caribbean spiny lobster (Panulirus argus) and the hardbottom habitats found north of the island of Marathon. We characterized these habitats based on benthic cover (e.g., algae, seagrass) and density of lobster refuge (e.g., coral, sponges, octocorals, solution holes, rocky ledges) to determine how specific habitat characteristics affect lobster abundance and ...


Hairy Stalagmites, A New Biogenic Root Speleothem From Botswana, Gerhard C. Du Preez, Paolo Forti, Gerhard Jacobs, Anine Jordaan, Louwrens Tiedt Nov 2014

Hairy Stalagmites, A New Biogenic Root Speleothem From Botswana, Gerhard C. Du Preez, Paolo Forti, Gerhard Jacobs, Anine Jordaan, Louwrens Tiedt

International Journal of Speleology

Ngamiland in northwestern Botswana hosts the Gcwihaba Caves which present unique subterranean environments and host speleothems never before recorded. Cave atmospheric conditions can be extreme with temperatures as high as 28°C and relative humidity nearing 99.9%. Within Dimapo and Diviner’s Caves peculiar root speleothems that we named ‘Hairy Stalagmites’ were found. These stalagmites are closely associated with the roots of Namaqua fig (Ficus cordata) trees that enter the cave environment in search of water. Pieces of broken stalagmites were sampled from Dimapo Cave for further investigations. Stereo and electron microscopy revealed that the Hairy Stalagmites consist of ...

Parental Involvement During Adolescence And Contraceptive Use In College, Caroline Payne Purvis, Rosemary V. Barnett, Larry Forthun Nov 2014

Parental Involvement During Adolescence And Contraceptive Use In College, Caroline Payne Purvis, Rosemary V. Barnett, Larry Forthun

Journal of Adolescent and Family Health

The current study aimed to explore the relationships between parental involvement during adolescence on sexual behaviors among college students. Research has shown that parental involvement decreases as students move from high school to college, but the impact that parents had on their students while in high school continues into college. It is important to determine if one factor relating to the number of sexual partners, sexual activity, and contraceptive use is parental involvement during adolescence. After approval from the Institutional Review Board (IRB), an online survey using Survey Monkey was administered to a convenience sample of undergraduate students in a ...

An Active Role For The Ribosome In Determining The Fate Of Oxidized Mrna, Carrie L. Simms, Benjamin H. Hudson, John W. Mosior, Ali S. Rangwala, Hani S. Zaher

Biology Faculty Publications

Chemical damage to RNA affects its functional properties and thus may pose a significant hurdle to the translational apparatus; however, the effects of damaged mRNA on the speed and accuracy of the decoding process and their interplay with quality-control processes are not known. Here, we systematically explore the effects of oxidative damage on the decoding process using a well-defined bacterial in vitro translation system. We find that the oxidative lesion 8-oxoguanosine (8-oxoG) reduces the rate of peptide-bond formation by more than three orders of magnitude independent of its position within the codon. Interestingly, 8-oxoG had little effect on the fidelity ...


Glucose Significantly Enhances Enterotoxigenic Escherichia Coli Adherence To Intestinal Epithelial Cells Through Its Effects On Heat-Labile Enterotoxin Production, Prageeth Wijemanne, Rodney A. Moxley Nov 2014

Glucose Significantly Enhances Enterotoxigenic Escherichia Coli Adherence To Intestinal Epithelial Cells Through Its Effects On Heat-Labile Enterotoxin Production, Prageeth Wijemanne, Rodney A. Moxley

Papers in Veterinary and Biomedical Science

The present study tested whether exposure of enterotoxigenic Escherichia coli (ETEC) to glucose at different concentrations in the media results in increased bacterial adherence to host cells through increased heat-labile enterotoxin (LT) production, thereby suggesting the effects are physiological. Porcine-origin ETEC strains grown in Casamino acid yeast extract medium containing different concentrations of glucose were washed and inoculated onto IPEC-J2 porcine intestinal epithelial cells to test for effects on adherence and host cell cAMP concentrations. Consistent with previous studies, all LT+ strains had higher ETEC adherence to IPEC-J2 cells than did LT2 strains. Adherence of the LT2 but not the ...


Testing Gene-Environment Interactions In The Presence Of Measurement Error, Chongzhi Di, Li Hsu, Charles Kooperberg, Alex Reiner, Ross Prentice Nov 2014

Testing Gene-Environment Interactions In The Presence Of Measurement Error, Chongzhi Di, Li Hsu, Charles Kooperberg, Alex Reiner, Ross Prentice

UW Biostatistics Working Paper Series

Complex diseases result from an interplay between genetic and environmental risk factors, and it is of great interest to study the gene-environment interaction (GxE) to understand the etiology of complex diseases. Recent developments in genetics field allows one to study GxE systematically. However, one difficulty with GxE arises from the fact that environmental exposures are often measured with error. In this paper, we focus on testing GxE when the environmental exposure E is subject to measurement error. Surprisingly, contrast to the well-established results that the naive test ignoring measurement error is valid in testing the main effects, we find that ...

Influence Of Nitrogen Fertilizer And Foliar Application Of Salicylic Acid On Wheat, Omar Maghawri Ibrahim Hassan Dr.

Dr. Omar Maghawri Ibrahim

Two cemented plots experiments were carried out during the winter seasons of 2012/2013 and 2013/2014, Soil Salinity Laboratory, Alexandria, Egypt, to study the effect of three levels of salicylic acid (SA) (0, 50, 100 ppm) and three rates of nitrogen fertilizer (75, 100, 125 kg N/feddan) on yield and yield components of wheat (Sakha 93). The experimental design was split plot with four replicates. The results indicated that increasing nitrogen fertilizer rates resulted in significant increase in plant height (cm), number of grain/spike, number of spikes/m2, 1000 grain weight (gm), grain yield (gm/plot), straw ...


The Reduction Of Metabolic Cost While Using Handrail Support During Inclined Treadmill Walking Is Dependent On The Handrail-Use Instruction, Cory Hofmann, Connor Dougherty, Hagop Abkarian, Michele Fox, Paul Juris Nov 2014

The Reduction Of Metabolic Cost While Using Handrail Support During Inclined Treadmill Walking Is Dependent On The Handrail-Use Instruction, Cory Hofmann, Connor Dougherty, Hagop Abkarian, Michele Fox, Paul Juris

International Journal of Exercise Science

International Journal of Exercise Science 7(4) : 339-345, 2014. Inclined treadmill walking is a commonly performed activity to increase cardiovascular health. Handrail support on a treadmill provides an individual the opportunity to change their posture with respect to the walking surface. Differences in metabolic cost during inclined walking due to postural changes with handrail use are unknown. To test the hypothesis that metabolic cost will differ depending on how handrail support is used, respiratory gas analysis was performed during inclined walking in 13 healthy subjects. Energy expenditure was quantified while each subject walked in four conditions: 5% incline unsupported, 10 ...

Grocery Store Botany, Laura K. Thompson Dr

Biology Publications

The vast majority of the plants we consume in our diets are Angiosperms, the most common plants on Earth today. Angiosperms are the plants we encounter most frequently not only in the landscape, but also in the grocery store. In this laboratory, we use grocery store vegetables to examine how Angiosperms are constructed. The study of body form is called morphology, a term coined by the German poet Goethe. As we see in this laboratory, Angiosperms can have diverse morphology. Even among the relatively few domesticated plants we use for food, we find a wide range of forms in the ...
