Effects Of A 21 Day Simvastatin Treatment On Exercise Performance In Sprague Dawley Rats, Mohammad M. Kabir Aug 2012

Effects Of A 21 Day Simvastatin Treatment On Exercise Performance In Sprague Dawley Rats, Mohammad M. Kabir

Electronic Theses and Dissertations Archive

Statins are widely used cholesterol loweing durgs that have shown to have many benefits. However, some studies have shown that statin treatment can lead to potential side effects, especially with exercise. We looked at the effects of a 21-day statin treatment on exercise performance in male Sprague Dawley rats. The rats were trained for 12 days and performed a maximal exercise test on the final day of the study. Time to exhaustion was used as the primary marker of performance and we noted a significant difference between the statin group and placebo group for time to exhaustion. Masses of heart, …

Sampling And Ontologically Pooling Web Images For Visual Concept Learning, Shiai Zhu, Chong-Wah Ngo, Yu-Gang Jiang Aug 2012

Sampling And Ontologically Pooling Web Images For Visual Concept Learning, Shiai Zhu, Chong-Wah Ngo, Yu-Gang Jiang

Research Collection School Of Computing and Information Systems

Sufficient training examples are essential for effective learning of semantic visual concepts. In practice, however, acquiring noise-free training examples has always been expensive. Recently the rapid popularization of social media websites, such as Flickr, has made it possible to collect training exemplars without human assistance. This paper proposes a novel and efficient approach to collect training samples from the noisily tagged Web images for visual concept learning, where we try to maximize two important criteria, relevancy and coverage, of the automatically generated training sets. For the former, a simple method named semantic field is introduced to handle the imprecise and …

The Performance Of Art: Picasso, Léger, And Modern Dance, 1917-1925, Amanda Holly Beresford Aug 2012

The Performance Of Art: Picasso, Léger, And Modern Dance, 1917-1925, Amanda Holly Beresford

All Theses and Dissertations (ETDs)

This thesis examines the phenomenon of easel painters designing for ballet companies in Paris in the 1910s and 1920s. It focuses on the work of Picasso for Diaghilev's Ballets Russes and Léger for De Maré's Ballets Suédois between 1917 and 1925, and considers the consequences for these artists' studio practice of their involvement in dance theatre. Their work is situated in the historical context of Wagner’s influential notion of the Gesamtkunstwerk—total theatre synthesizing all the arts, including painting—and its reinterpretation by avant-garde theatre practitioners from the mid-nineteenth into the early twentieth century. Picasso’s and Léger’s stage designs reveal the dynamic …

Effects Of Oak Savanna Restoration And Thinning On Gypsy Moth Predation Rates And Small Mammal Communities, Angela Lynn Larsen Aug 2012

Effects Of Oak Savanna Restoration And Thinning On Gypsy Moth Predation Rates And Small Mammal Communities, Angela Lynn Larsen

Masters Theses

The United States Forest Service is conducting an oak savanna restoration using thinning and prescribed burning in the Manistee National Forest in Michigan to provide habitat for Karner blue butterflies (Lycaeides melissa samuelis). Since this is a federally endangered species, alternatives to spraying pesticides to control exotic invasive defoliators, such as European gypsy moths (Lymantria dispar), are necessary. Although gypsy moths are invasive to North America, there are several predators, such as whitefooted mice (Peromyscus leucopus), other small mammals, invertebrates, and parasitoids, keeping gypsy moth populations low. This study investigated whether the interaction between …

Winter Habitat Selection And Genetic Relatedness Of Southern Flying Squirrels In Southwest Michigan, Sheila M. Miara Aug 2012

Winter Habitat Selection And Genetic Relatedness Of Southern Flying Squirrels In Southwest Michigan, Sheila M. Miara

Masters Theses

Few studies have examined winter habitat selection for southern flying squirrels (Glaucomys volans) in northern latitudes where winter conditions are harsher than southern latitudes and resource availability is particularly limiting. Winter den tree characteristics and use by 19 southern flying squirrels (10 females and 9 males) were investigated from November through February in 2010-2011 and 2011-2012. The mean home range size using 100% minimum convex polygon for 18 individuals was 3.40 ha (±0.46 0.46 SE) and there was no significant difference between genders (P= 0.56) or ages (P=0.50). The mean 95% fixed kernel home range size was 0.15 …

Understanding The Pathoecological Relationship Between Ancient Diet And Modern Diabetes Through Coprolite Analysis: A Case Example From Antelope Cave, Mojave County, Arizona, Karl J. Reinhard, Keith L. Johnson, Sara Leroy-Toren, Kyle Wieseman, Isabel Teixeira-Santos, Mônica Vieira Aug 2012

Understanding The Pathoecological Relationship Between Ancient Diet And Modern Diabetes Through Coprolite Analysis: A Case Example From Antelope Cave, Mojave County, Arizona, Karl J. Reinhard, Keith L. Johnson, Sara Leroy-Toren, Kyle Wieseman, Isabel Teixeira-Santos, Mônica Vieira

School of Natural Resources: Faculty Publications

The elevated prevalence of non-insulin-dependent diabetes mellitus (NIDDM) in Native Americans of the Southwest has been explained by several authors in terms of a dietary change from preindustrial traditional foods to modern foods. Physiology adapted to traditional foods became deleterious during the process of modernization. Although several versions of this hypothesis exist, they all relate to the rise in modern NIDDM with change from prehistoric subsistence practices to modern dietary practices. This is especially true for the Southwestern desert tribes of Arizona and New Mexico. Coprolite analysts have been recovering the sort of data needed by diabetes researchers to explore …

In Vivo Quantification Reveals Extensive Natural Variation In Mitochondrial Form And Function In Caenorhabditis Briggsae, Kiley Ann Hicks, Dana K. Howe, Aubrey Leung, Dee R. Denver, Suzanne Estes Aug 2012

In Vivo Quantification Reveals Extensive Natural Variation In Mitochondrial Form And Function In Caenorhabditis Briggsae, Kiley Ann Hicks, Dana K. Howe, Aubrey Leung, Dee R. Denver, Suzanne Estes

Biology Faculty Publications and Presentations

We have analyzed natural variation in mitochondrial form and function among a set of Caenorhabditis briggsae isolates known to harbor mitochondrial DNA structural variation in the form of a heteroplasmic nad5 gene deletion (nad5Δ) that correlates negatively with organismal fitness. We performed in vivo quantification of 24 mitochondrial phenotypes including reactive oxygen species level, membrane potential, and aspects of organelle morphology, and observed significant among- isolate variation in 18 traits. Although several mitochondrial phenotypes were non-linearly associated with nad5Δ levels, most of the among-isolate phenotypic variation could be accounted for by phylogeographic clade membership. In particular, isolate-specific mitochondrial membrane potential …

Bridging Developmental Neuroscience And The Law: Child-Caregiver Relationships, Ross A. Thompson Aug 2012

Bridging Developmental Neuroscience And The Law: Child-Caregiver Relationships, Ross A. Thompson

UC Law Journal

Advances in neuroscience are changing understanding of the biological foundations of human development and have implications for legal analysis. As with any period of rapid scientific progress, however, new ideas are subject to misinterpretation and errors in application. This Article offers guidance on how to avoid such problems and consider carefully the applications of developmental neuroscience to legal policy and practice, with a particular emphasis on caregiver-child relationships. Three principles are discussed. First, the most confident applications of developmental neuroscience to legal policy occur when the conclusions of neuroscience are consistent with those of behavioral research. This is because their …

The Neurobiology Of Attachment To Nurturing And Abusive Caregivers, Regina M. Sullivan Aug 2012

The Neurobiology Of Attachment To Nurturing And Abusive Caregivers, Regina M. Sullivan

UC Law Journal

Decades of research have shown that childhood experiences interact with our genetics to change the structure and function of the brain. Within the range of normal experiences, this system enables the brain to be modified during development to adapt to various environments and cultures. Experiences with and attachment to the caregiver appear particularly important, and recent research suggests this may be due, in part, to the attachment circuitry within the brain. Children have brain circuitry to ensure attachment to their caregivers. Attachment depends on the offspring learning about the caregiver in a process that begins prenatally and continues through most …

Creating A Clearinghouse To Evaluate Environmental Risks To Fetal Development, Kate E. Bloch Aug 2012

Creating A Clearinghouse To Evaluate Environmental Risks To Fetal Development, Kate E. Bloch

UC Law Journal

In this Article, the Author explores current challenges to accessing and evaluating information about environmental risks to fetal development. She investigates these challenges within the context of the existing regulatory framework for environmental risks. As a result of this analysis, she highlights the need for and proposes creating an independent non-profit umbrella organization—a clearinghouse—to collect, distill, interpret, and make accessible the research on environmental threats to fetal development and to apply that research to evaluating relevant U.S. policy. The Author defines broadly the research on fetal development that lies within the charge of the clearinghouse to include not only research …

Mini-Review: Decorin, A Guardian From The Matrix, Thomas Neill, Liliana Schaefer, Renato V. Iozzo Aug 2012

Mini-Review: Decorin, A Guardian From The Matrix, Thomas Neill, Liliana Schaefer, Renato V. Iozzo

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Decorin, an archetypal member of the small leucine-rich proteoglycan gene family, has a broad binding repertoire that encompasses matrix structural components, such as collagens, and growth factors, particularly those that belong to the transforming growth factor-β ligand superfamily. Within the tumor microenvironment, stromal decorin has an inherent proclivity to directly bind and down-regulate several receptor tyrosine kinases, which are often overexpressed in cancer cells. The decorin interactome commands a powerful antitumorigenic signal by potently repressing and attenuating tumor cell proliferation, survival, migration, and angiogenesis. This collection of interacting molecules also regulates key downstream signaling processes indirectly via the sequestration of …

Interactions Among Positions In The Third And Fourth Membrane-Associated Domains At The Intersubunit Interface Of The N-Methyl-D-Aspartate Receptor Forming Sites Of Alcohol Action, Hong Ren, Yulin Zhao, Donard S. Dwyer, Robert W. Peoples Aug 2012

Interactions Among Positions In The Third And Fourth Membrane-Associated Domains At The Intersubunit Interface Of The N-Methyl-D-Aspartate Receptor Forming Sites Of Alcohol Action, Hong Ren, Yulin Zhao, Donard S. Dwyer, Robert W. Peoples

Biomedical Sciences Faculty Research and Publications

The N-methyl-d-aspartate (NMDA) glutamate receptor is a major target of ethanol in the brain. Previous studies have identified positions in the third and fourth membrane-associated (M) domains of the NMDA receptor GluN1 and GluN2A subunits that influence alcohol sensitivity. The predicted structure of the NMDA receptor, based on that of the related GluA2 subunit, indicates a close apposition of the alcohol-sensitive positions in M3 and M4 between the two subunit types. We tested the hypothesis that these positions interact to regulate receptor kinetics and ethanol sensitivity by using dual substitution mutants. In single-substitution mutants, we found that a position …

Measurement Of The Oxidation State Of Mitochondrial Cytochrome C From The Neocortex Of The Mammalian Brain, Y. Sakata, M. Abajian, M. O. Ripple, R. Springett

Dartmouth Scholarship

Diffuse optical remission spectra from the mammalian neocortex at visible wavelengths contain spectral features originating from the mitochondria. A new algorithm is presented, based on analytically relating the first differential of the attenuation spectrum to the first differential of the chromophore spectra, that can separate and calculate the oxidation state of cytochrome c as well as the absolute concentration and saturation of hemoglobin. The algorithm is validated in phantoms and then tested on the neocortex of the rat during an anoxic challenge. Implementation of the algorithm will provide detailed information of mitochondrial oxygenation and mitochondrial function in physiological studies of …

Bones In The Landfill: A Zooarchaeological Study From Faneuil Hall, Linda M. Santoro Aug 2012

Bones In The Landfill: A Zooarchaeological Study From Faneuil Hall, Linda M. Santoro

Graduate Masters Theses

Using data from recent archaeological excavations at Faneuil Hall in Boston, this thesis examines how an 18th-century urban landfill context can be used towards understanding the broader foodways of a city community. Much of today's urban landscape has been artificially created over time, often through the efforts of communities to fill land and dispose of their garbage, and it is important for archaeologists to utilize these contexts in meaningful ways. The Town Dock was gradually filled in with the daily trash of the merchants, shop-keepers, and other residents of the nearby community, and the faunal assemblage gives us a glimpse …

Independent Component Analysis Of Event-Related Electroencephalography During Speech And Non-Speech Discrimination: : Implications For The Sensorimotor ∆∞ Rhythm In Speech Processing, Andrew Lee Bowers Aug 2012

Independent Component Analysis Of Event-Related Electroencephalography During Speech And Non-Speech Discrimination: : Implications For The Sensorimotor ∆∞ Rhythm In Speech Processing, Andrew Lee Bowers

Theses and Dissertations (ETD)

Background: The functional significance of sensorimotor integration in acoustic speech processing is unclear despite more than three decades of neuroimaging research. Constructivist theories have long speculated that listeners make predictions about articulatory goals functioning to weight sensory analysis toward expected acoustic features (e.g. analysis-by-synthesis; internal models). Direct-realist accounts posit that sensorimotor integration is achieved via a direct match between incoming acoustic cues and articulatory gestures. A method capable of favoring one account over the other requires an ongoing, high-temporal resolution measure of sensorimotor cortical activity prior to and following acoustic input. Although scalp-recorded electroencephalography (EEG) provides a measure of cortical …

Responses To Predator Recognition Odors In Marmorkrebs, Loren Samantha Beard Aug 2012

Responses To Predator Recognition Odors In Marmorkrebs, Loren Samantha Beard

Theses and Dissertations - UTB/UTPA

Marmorkrebs is a parthenogenetic crayfish with no indigenous populations. They have been introduced in several countries and could become an invasive species. Individuals introduced in Germany had longer, sharper spines, suggesting an adaptation to predators via developmental plasticity. This was tested by exposing juveniles to the odor of a fish during development and comparing them to controls. Subsequent spine length or sharpness did not differ. Other crayfish detect predators via an alarm cue, hemolymph, and exhibit avoidant behavior in response. I hypothesized that Marmorkrebs would also treat hemolymph as an alarm cue. The behavior of adult crayfish exposed to food, …

African Slavery In Colonial Veracruz: The Factors That Aided Its Creation And Expansion, Veronica Nohemi Duran Aug 2012

African Slavery In Colonial Veracruz: The Factors That Aided Its Creation And Expansion, Veronica Nohemi Duran

Theses and Dissertations - UTB/UTPA

The focal point of this study is to prove that it was the simultaneous presence of five factors during the 16th and 17th centuries that allowed African enslavement in Veracruz to expand. I built upon previous works and authors to support my claim that it was the decline in native population, economic profits, religious apathy on the subject, social acceptance and government support that pushed for the systems creation and expansion. By discussing each of these factors in a chapter of their own, I concluded that in an almost cause and effect manner these factors are responsible for the expansion …

Comparisons Of Emotional Reactivity In Two Variations Of Schedules Of Reinforcement, Mayra A. Aguillon Aug 2012

Comparisons Of Emotional Reactivity In Two Variations Of Schedules Of Reinforcement, Mayra A. Aguillon

Theses and Dissertations - UTB/UTPA

Operant conditioning is a type of learning in which the frequency of behavior is affected by its consequences (Powell, Symbaluk & Honey 2009).The main focus of the study was to compare two different schedules of reinforcement: gradual group versus the abrupt group (FI-20 sec).Both groups were used to observe emotional reactivity in 8 Sprague Dawley female rats from the Behavioral Neuroscience lab at UTPA. The hypothesis presented was that animals will reveal less emotional reactivity in the gradual than in the abrupt. According to Skinner, behavior is affected more by the consequence that is followed. Results suggested that the abrupt …
