The Roles Of Carma1 And Pkcθ In T Cell Function And Immunity, Katy Korzekwa

Biomedical Sciences ETDs

T cells are critical players in adaptive immunity. They migrate throughout the body scanning the lymph nodes for antigen, then migrate to an infection site to help clear pathogen. Migrating T cells use multiple receptors and adhesion proteins to migrate to and enter different tissues. While the cell surface molecules involved in T cell motility are well understood, less is known about intracellular signaling pathways involved in T cell migration. PKCθ and CARMA1 signal downstream of TCR activation to induce NF-κB activation. However, the roles of PKCθ and CARMA1 in other T cell functions are unknown. In this study we …

Cd82 Regulation Of Hematopoietic Stem/Progenitor Cell - Niche Adhesion, Maura L. Cotter

Biomedical Sciences ETDs

The spatial organization and dynamics of proteins and lipids within the cell membrane is important for the regulation of cell signaling, adhesion, and cell communication. Within the bone marrow niche, communication between hematopoietic stem/progenitor cells (HSPCs) and niche cells is essential for regulating their proliferation, differentiation, and survival. Our previous work has ascertained that HSPCs utilize a polarized domain on the plasma membrane that serves as the contact site with osteoblasts, which are important members of the bone marrow niche. Using human primary CD34+ stem/progenitor cells and the progenitor-like KG1a cell line, we found this domain to be enriched in …

Survival Of White-Tailed Deer Fawns In The Grasslands Of The Northern Great Plains, Troy W. Grovenburg, Robert W. Klaver, Jonathan A. Jenks

Natural Resource Management Faculty Publications

Environmental factors, such as forest characteristics, have been linked to fawn survival in eastern and southern white-tailed deer ( Odocoileus virginianus) populations. In the Great Plains, less is known about how intrinsic and habitat factors influence fawn survival. During 2007-2009, we captured and radiocollared 81 fawns in north-central South Dakota and recorded 23 mortalities, of which 18 died before 1 September. Predation accounted for 52.2% of mortality; remaining mortality included human (hunting, vehicle, and farm accident; 26.1%) and hypothermia (21.7%). Coyotes (Canis latrans) accounted for 83.3% of predation on fawns. We used known-fate analysis in Program MARK to estimate summer …

Effect Of Flow On Human Endothelial Cell And Dermal Cell Growth Rates Supplemented With Drug Infused Media., Daniel Baumann

Electronic Theses and Dissertations

Wounds care and management is one of the most basic needs in the medical setting. Burn wounds, trauma wounds, pressure ulcers and bedsores are just some of the many types of wounds that need to be treated quickly and efficiently. Take for instance pressure ulcers, there at least 3 million reported cases of chronic ulcers and bedsores reported in the U.S. each year alone. Each ulcer can takes weeks to months to fully heal, leading to extended hospital stays and decreased quality of life in patients. Current treatment seeks to protect and keep the wound clean, manage cellular exudates, and …

Electrokinetic Colloid Patterning Characterization With A Scanning Laser., Andrew Hardesty Work

Electronic Theses and Dissertations

Rapid Electrokinetic Patterning (REP) is a relatively new method for collecting and manipulating micrometer-scale particles at an electrode surface. REP is an AC electrokinetic technique that uses induced fluid motion to capture and manipulate particles. A laser (975 nm) is focused on the surface of the parallel-plate electrode, generating a thermal gradient in the medium. This thermal gradient is acted upon by the AC electric field in such manner as to produce a vortex. Particles are trapped on the electrode surface at the center of the vortex. It is hypothesized that AC electroosmotic flows act to hold the particles to …

Production And Characterization Of Biodegradable Nanofibers Via Forcespinning™ Technology, Zachary T. Mceachin

Theses and Dissertations - UTB/UTPA

Among the myriad of methods for polymer nanofiber production, there are only a few methods that can produce submicron range fibers in bulk from melt or solution samples. The Forcespinning™ method allows a substantial increase in sample yield; this greatly reduces the time needed to produce bulk quantities of fibers which may be critical in many fields of research and industry, in particularly in fields relating to biopolymers. The aim of the first study was to utilize this method to form non-woven mats of polycaprolactone (PCL) nanofibers and to quantitatively analyze the production and characterization of the produced fibers. The …

Wing Shape As An Indicator Of Larval Rearing Conditions For Aedes Albopictus And Aedes Aegypti (Diptera: Culicidae), C R. Stephens, Steven A. Juliano

Faculty Publications – Biological Sciences

Estimating a mosquito's vector competence, or likelihood of transmitting disease, if it takes an infectious bloodmeal, is an important aspect of predicting when and where outbreaks of infectious diseases will occur. Vector competence can be affected by rearing temperature and inter- and intraspecific competition experienced by the individual mosquito during its larval development. This research investigates whether a new morphological indicator of larval rearing conditions, wing shape, can be used to distinguish reliably temperature and competitive conditions experienced during larval stages. Aedes albopictus (Skuse) and Aedes aegypti (L.) (Diptera: Culicidae) larvae were reared in low intraspecific, high intraspecific, or high …

Little investigation has been conducted on the use of Personal Response Systems (PRS) in either graduate-level courses or health professions education. Through anonymous participation in focus groups, graduate physical therapy students described specific aspects of PRS that they felt facilitated their learning, as well as aspects that hindered their learning. A Likert-type survey was constructed based on focus group outcomes and was offered to the entire population of physical therapy students at our institution. Results indicated that PRS was perceived to be useful for examination preparation, application of concepts, facilitation of discussion, and immediate feedback. Participants perceived cost and technical …

Assessing Pesticide Reduction In Constructed Wetlands Using A Tanks-In-Series Model Within A Bayesian Framework, Pamela Krone-Davis

SNS Master's Theses

Frequent pesticide detection at toxic levels to test organisms in California's Central Coast waterbodies has motivated regulators, resource agencies and end-users to investigate and adopt management practices and technologies to diminish agricultural chemicals entering receiving waters. Treatment wetlands are a technology of special interest because of their ability to simultaneously treat multiple pollutants commonly found in agricultural and urban runoff including nitrate, suspended sediment and pesticides. We sought evidence for transformation of three highly water soluble pesticides (diazinon, methomyl and acephate) in a full-scale constructed treatment wetland located at the base of the Salinas Valley. We pumped water into the …
