Effects Of Wildfires On Tree Establishment In Conifer-Dominated Boreal Forests In Southern Northwest Territories, Kirsten Reid

Theses and Dissertations (Comprehensive)

Black spruce (Picea mariana) and jack pine (Pinus banksiana) both release a large majority of their seeds after fire and thus experience large pulses of recruitment during these punctuated events. Global warming is driving intensification of the wildfire regime in the boreal forest, which is resulting in shifts from coniferous to deciduous dominated forests in some parts of the boreal forest of North America. This shift can present consequences for forest structure, ecosystem dynamics, carbon cycling, and wildlife habitat.

During 2014, the Northwest Territories experienced a historically unprecedented fire year with 3.4 million hectares of forest …

Structure-Function Investigation Of Proteins Involved In Cellulose Biosynthesis By Escherichia Coli, Thomas Brenner

Theses and Dissertations (Comprehensive)

Bacteria thrive within multicellular communities called biofilms consisting of a self-produced matrix. Biofilm matrices improve bacterial adherence to surfaces while creating a barrier from host immune responses, disinfectants, antibiotics and other environmental factors. Persistent colonization by the widely distributed pathogens, Escherichia coli and Salmonella spp., has been linked to production of biofilms composed of the exopolysaccharide cellulose. Cellulose-containing biofilms are also important to Acetobacter, Sarcina, Rhizobium and Agrobacterium species to form symbiotic and pathogenic interactions. In Enterobacteriaceae, two operons (bcsABZC and bcsEFG) are proposed to encode for proteins that form a cellulose biosynthetic complex that spans the …

The Effects Of A 12-Week Custom Foot Orthotic Intervention On The Intrinsic Muscles Of The Foot, And Dynamic Stability During Unexpected Gait Termination In Healthy Young Adults, Katrina Protopapas

Theses and Dissertations (Comprehensive)

Introduction: Custom-made foot orthotics (CFO’s) are a commonly prescribed intervention to help individuals that are suffering from foot pain and foot disorders. However, the mechanisms of CFO’s are still poorly understood and are not well known. With the plantar intrinsic muscles of the foot being in direct contact with the CFO, it puts these structures at risk for disuse muscle atrophy as a result of being offloaded. Therefore, the purpose of the current study was to determine the effect of a 12-week custom-made foot orthotic intervention on the intrinsic muscles of the foot and dynamic stability during unexpected gait termination. …

Peripheral Visual Motion Sensitivity In Previously Concussed, Asymptomatic Individuals, Alyssa Prangley

Theses and Dissertations (Comprehensive)

Background: Individuals acquire information about self-motion from the environment which specifies actions necessary to be successful (Fajen & Matthis, 2011). However, concussed individuals demonstrate residual disturbance in execution of postural movement at 30 days post injury, depicting an impaired ability to perceive self-motion in a visually conflicting environment (Slobounov et al. 2006). The objective of this thesis was to investigate the extent to which one’s behaviours on a central field of view task are influenced by the amount and type of peripheral visual movement during a collision avoidance task, as well as to determine the additive effects of changes to …

Variation In Models For Simple Dynamic Structure-Soil-Structure Interaction Problems, L. V. Andersen, A. Peplow, P. Bucinskas, P. Persson, K. Persson

All Works

© 2017 The Authors. Published by Elsevier Ltd. To account for dynamic cross-coupling of structures via the soil, a computational model must be accurate enough to provide the correct overall behaviour of the scattered wave field. However, simplicity is also important when a model should be used for design purposes, especially in the early design stages and feasibility studies. The paper addresses the accuracy of simple models in which an array of structures is simplified into blocks placed on the ground surface or embedded within the soil. Comparisons are made between models that account or do not account, in a …

Evidence Of A Perilipin 5 Splice Variant, Brodie Ranzau

Undergraduate Honors Thesis Projects

Alternative splicing occurs throughout the human genome, leading to multiple proteins from a single gene. The resulting proteins can be nearly identical or vastly different in how they function. Alternative splicing within the perilipin family has been observed in perilipins 1 and 3, giving rise to proteins with varying functions. In the course of our studies on perilipin 5, an immunoblot signal was observed that corresponded to an approximately 35 kDa protein. Western blot analysis of this protein has revealed its expression in C2C12 cultured myoblasts and in heart and liver mouse tissue. Further analysis of perilipin 5 cDNA through …

Expression, Purification And Characterization Of Lysine Methyltransferase Smyd5, Wen Xue

Wayne State University Theses

Methylation of histones and non-histone proteins play vital roles in numerous cellular processes including gene expression regulation and DNA damage response. The identifications of methyltransferase SMYD protein family are not well characterized. SMYD5 is a unique and critical member of SMYD family involved in immune response, stem cell renew, hematopoiesis regulation and cancer metastasis. Understanding its function and structure is monumental to human disease. With the achievement of SMYD5 expression and purification, the association between SMYD5 and its substrate histone H4 has been investigated. While possessing a poly-E tail instead of the TPR domain included in other members, SMYD5 is …

Comparison Of Lumbo-Pelvic Kinematics During Trunk Forward Bending And Backward Return Between Patients With Acute Low Back Pain And Asymptomatic Controls, Iman Shojaei, Elizabeth G. Salt, Quenten L. Hooker, Linda R. Van Dillen, Babak Bazrgari

Biomedical Engineering Faculty Publications

Background—Prior studies have reported differences in lumbo-pelvic kinematics during a trunk forward bending and backward return task between individuals with and without chronic low back pain; yet, the literature on lumbo-pelvic kinematics of patients with acute low back pain is scant. Therefore, the purpose of this study was set to investigate lumbo-pelvic kinematics in this cohort.

Methods—A case-control study was conducted to investigate the differences in pelvic and thoracic rotation along with lumbar flexion as well as their first and second time derivatives between females with and without acute low back pain. Participants in each group completed one …
