Detection Of Mitochondrial Insertions In The Nucleus (Numts) Of Pleistocene And Modern Muskoxen, Sergios-Orestis Kolokotronis, Ross De Macphee, Alex D. Greenwood

Biological Sciences Faculty Publications

Background: Nuclear insertions of mitochondrial sequences (NuMts) have been identified in a wide variety of organisms. Trafficking of genetic material from the mitochondria to the nucleus has occurred frequently during mammalian evolution and can lead to the production of a large pool of sequences with varying degrees of homology to organellar mitochondrial DNA (mtDNA) sequences. This presents both opportunities and challenges for forensics, population genetics, evolutionary genetics, conservation biology and the study of DNA from ancient samples. Here we present a case in which difficulties in ascertaining the organellar mtDNA sequence from modern samples hindered their comparison to ancient DNA …

Structural Attributes Of The Hypogeous Holoparasite Hydnora Triceps Drège & Meyer (Hydnoraceae), Kushan U. Tennakoon, Jay F. Bolin, Lytton J. Musselman, Erika Maas

Biological Sciences Faculty Publications

The morphology of the hypogeous root holoparasite Hydnora triceps is highly reduced, and as with many holoparasites, the vegetative body is difficult to interpret. The vegetative body of H. triceps has been historically considered a "pilot root" studded with lateral appendages known as "haustorial roots." We found the vegetative body of H. triceps to consist of a rhizome with a thickened root-cap-like structure that covered a vegetative shoot apical meristem. From the apical meristem, procambial strands originated and developed into endarch collateral vascular bundles arranged radially around a pith without an interfascicular cambium. Xylem vessels had scalariform pitting and simple …

Habitat Correlates Of Reproductive Effort In Wood Frogs And Spotted Salamanders In An Urbanizing Watershed, Dennis E. Skidds, Francis C. Golet, Peter W. C. Paton, Jonathan C. Mitchell

Natural Resources Science Faculty Publications

Wildlife biologists and managers are concerned about the effects of forest fragmentation and habitat loss on pond-breeding amphibian populations. Most research has assessed the effects of habitat composition at multiple spatial scales on the presence or absence of amphibians at breeding ponds. We were interested in the effects of habitat characteristics on amphibian population size and used Wood Frog (Rana sylvatica) and Spotted Salamander (Ambystoma maculatum) egg mass counts as an index. Between 2001 and 2005, we monitored 65 seasonal ponds within forested landscapes in the Pawcatuck River watershed of Rhode Island. Both species were detected …

Reduction Of Astrogliosis And Microgliosis By Cerebrospinal Fluid Shunting In Experimental Hydrocephalus, Janet M. Miller, James P. Mcallister Ii

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Reactive gliosis has the potential to alter biomechanical properties of the brain, impede neuronal regeneration and affect plasticity. Determining the onset and progression of reactive astrogliosis and microgliosis due to hydrocephalus is important for designing better clinical treatments.

Methods

Reactive astrogliosis and microgliosis were evaluated as the severity of hydrocephalus increased with age in hydrocephalic H-Tx rats and control littermates. Previous studies have suggested that gliosis may persist after short-term drainage (shunt treatment) of the cerebrospinal fluid. Therefore shunts were placed in 15d hydrocephalic rats that were sacrificed after 6d (21d of age) or after 21d (36d of …

Mosquito Larval Habitats In A Semiarid Ecosystem In Eritrea: Impact Of Larval Habitat Management On Anopheles Arabiensis Population, Josephat Shililu, Charles Mbogo, Tewolde Ghebremeskel, John Githure, Robert Novak

All Peer-Reviewed Publications

This study investigated the impact of larval management and the temporal variation in larval productivity in Eritrea, a semiarid ecosystem. Results of this study show that mosquito breeding persists throughout the year mainly in stream bed pools. Anopheles arabiensis production in the ephemeral natural aquatic habitats such the streambed pools was high throughout the year and negatively associated with rainfall (r = -0.288, P = 0.047). High densities of An. arabiensis larvae were also recorded from canals and drainage channels at wells and communal water supply points. The numerous water supply locations and wells help sustain malaria transmission by serving …

Observations Of Rough-Toothed Dolphins (Steno Bredanensis) Off The Coast Of Utila, Honduras, Stan A. Kuczaj Ii, Deirdre Yeater

Psychology Faculty Publications

Local dive shop operators and fishermen report that rough-toothed dolphins (Steno bredanensis) are frequently encountered off the coast of Utila, Honduras, (16°05'46.5"N 86°55'47.8"W). Our observations suggest that at least some of these animals may constitute a resident population, although the extent of the resident group’s home range has not been determined. Twenty-eight rough-toothed dolphins were identified using photoidentification techniques, 15 of which were re-sighted on two or more occasions. The 12 animals that were re-sighted four or more times were typically seen together, suggesting that they constitute a stable social group. At least one of these dolphins is …

Supporting Personhood In Dementia: Examining The Impact Of Volition On Function In Everyday Occupations, Christine L. Raber

Theses and Dissertations

Understanding volition and preferences for occupation is a critical underpinning of effective occupational therapy services that promote and preserve identity for persons with moderate dementia. Although it has been posited that this population has significant difficulty expressing volition for daily occupations, little research has examined the role of volition in guiding engagement in occupations. This phenomenological study provides an in-depth description and analysis of volition in eight persons with moderate dementia. Guiding questions related to understanding patterns of past life interests, outward demonstration of volition, volitional continuity. and the relationship of the social environment to volition and engagement in daily …

Roles And Attitudes Of Males And Females In The Anarchist Punk Community, Donna M. Manion

Theses and Dissertations

Sexism is a widespread social problem that exists throughout the world today. It persists within the dominant culture, as well as in various subcultures, including the punk subculture (Daugherty 2002; Leblanc 1999; McRobbie 1991; Rosenberg and Garofalo 1998). Nijole Benokraitis and Joe Feagin's (1995) theory of sexism posits that subtle sexism is the unequal and harmful treatment of women that is typically less visible than blatant sex discrimination. This particular type of sexism may often go unnoticed, as society has internalized subtle sexist behaviors. Empirical research on subtle sexism has been conducted in various settings, such as the employment, academic, …

On The Binding Of N1-Substituted Tryptamines At H5-Ht6 Receptors, Abner Nyamwaro Nyandege

Theses and Dissertations

Serotonin was first discovered in the late 1940s as a vasotonic factor and is now considered a principal neurotransmitter in the nervous system. 5-HT6 receptors are one of the most recently identified members of the serotonin receptor family which consists of seven classes (5-HT1-5-HT7). 5-HT6 receptors are G-protein coupled, positively coupled to an adenylate cyclase second messenger system and are primarily found in the central nervous system (CNS). The exact functional role of 5-HT6 receptors has not been determined, but is implicated to have possible involvement in certain neuropsychiatric disorders and cognition. To investigate the functional role of these receptors, …

Camping In The Classroom: Ridiculous Theatre As Serious Drama, John Kenneth Deboer

Theses and Dissertations

My first semester pursuing my MFA in Voice and Speech Pedagogy I vocal-coached an openly gay student playing a straight character who would mask his sexual identity in such a manner that his performance became stiff and uninteresting. Rather than using his personal identity as an asset in the pursuit of a successful performance, his chosen vocal tactics removed any sense of theatricality from his performance. I confronted the student and suggested such extreme vocal suppression diminished the quality of his overall performance. He replied, "So you want me to get the gay out."His use of the phrase, "get the …

Electrospun Blends Of Polydioxanone And Fibrinogen For Urological Applications, Joshua Ford Grant

Theses and Dissertations

The need for tissue and organ replacements cannot be satisfied by autograft and allografts alone. The purpose of this study was to investigate the feasibility of electrospinning a blend of polydioxanone and fibrinogen to produce an engineered tissue scaffold. Fiber diameter and pore size of blends were characterized, as well as mechanical strength. Cell proliferation assays for 1 and 7 day cultures were preformed, and a histological evaluation was performed to determine how favorable the various blends were to cell infiltration and proliferation. Some ratios of blends were identified that contained both acceptable mechanical properties and properties that facilitated cell …

One Million Paintings 2005-2007: A Thesis, Jared Lindsay Clark

Theses and Dissertations

I assist discarded collectives of objects to volunteer themselves for inclusion into the privileged legacy of flatness – assuring them they can be transformed into Painting. Reducing my interventions - often to mere arrangement - respects the possibility of this transformation while frankly retaining the objects' original functional identities. Every surface of any object is a readymade painting – especially flat ones. By stacking objects and aligning their surfaces on one privileged side into a flat mega-surface, I am composing and collaging – even building – a painting. With my amateur interest in German I latch upon the double meaning …

Divergent Roles Of Pi3k And Akt In Rapamycin-Induced Cardioprotection Against Ischemia-Reperfusion Injury, Shivani Kirit Desai

Theses and Dissertations

Coronary heart disease (CHD) is one of the leading causes of death every year with nearly three-fourths of all deaths caused by the disease. The challenge scientists are facing today is discovering new drugs to protect the heart against cellular damage caused by ischemia-reperfusion injury (I-R injury). Rapamycin is one such drug that has been shown to protect the heart against ischemia-induced cellular injury. Rapamycin(sirolimus) inhibits protein synthesis through inhibition of the mammalian target ofrapamycin (mTOR). This property of rapamycin has led to its current clinical applications in drug-eluting stents and in immunosuppresive treatment to organ transplant patients. The mechanism …

The Role Of Inhibitory Interneurons In A Model Od Developmental Epilepsy, Patrick James Wolfgang

Theses and Dissertations

Epilepsy, defined by recurrent seizures, is the one of the most prevalent neurological disorders worldwide (World Health Organization 2007). While many forms of epilepsy are well-controlled by anti-epileptogenic medications, a significant portion of patients have intractable, i.e. untreatable, seizures. The etiology of these seizures is varied, but a significant cause, particularly for patients with intractable epilepsy is developmental malformation. In these cases, an error or interruption during the development of the neocortex produces a structural alteration. Such patients may have other neurological problems, but seizures are the most common symptom. The neuronal mechanisms that link malformation and cortical hyperexcitability are …

A Comparision Of Delta-9-Tetrahydrocannabinol Dependence In C57bl/6j Mice And Fatty Acid Amide Hydrolase Knock Out Mice, Brittany Leigh Alice Carlson

Theses and Dissertations

The idea that humans and laboratory animals can become physically dependent on marijuana or its primary psychoactive constituent, delta-9-tetrahydrocannabinol (THC), is gaining acceptance. However, there are no currently approved pharmacotherapies to treat cannabinoid withdrawal. The objective of this thesis was to evaluate whether elevating endogenous anandamide levels using mice lacking fatty acid amide hydrolase (FAAH), the enzyme responsible for anandamide metabolism, would ameliorate THC dependence. Mice were treated subchronically with a low or high THC dosing regimen and challenged with the CB1 receptor antagonist, rimonabant, to precipitate withdrawal. Following subchronic THC treatment, rimonabant precipitated a significant increase in paw flutters …
