Boundary Contour Based Surface Representation., Yong Su
Boundary Contour Based Surface Representation., Yong Su
Electronic Theses and Dissertations
We receive most information about our surrounding space and objects through the eyes. To reconstruct the 3D space and objects in the visual system from the 2D retinal images, surface representation must be a critical intermediate stage in the visual processing stream. It is hypothesized in the dissertation that the visual system represents textured surface by a border-to-interior strategy: boundary contours would be encoded first and then border-ownership assignments would be resolved. This process would solve the related problems such as figure-ground segregation, surface depth relationship, occlusion, transparency, etc. As a result, the boundary contours of the surfaces would be …
Effects Of Step Training On The Kidneys Following Spinal Cord Injury In Rats., Pradeepa Poudyal
Effects Of Step Training On The Kidneys Following Spinal Cord Injury In Rats., Pradeepa Poudyal
Electronic Theses and Dissertations
Detrusor-sphincter dyssynergia after chronic spinal cord injury (SCI) leads to over-distention, high bladder pressures and vesico-ureteric reflux into the kidney, resulting in repeated infections and pyelonephritis. Given the importance/limited knowledge of SCI effects on the upper urinary tract, this study assessed expression of two proteins in the kidneys of contused (T9) male rats relative to controls that are indicative of tissue stress/damage (TGFβ, CD11b). The impact of two therapeutic rehabilitation strategies, 60 minutes of step training and general exercise, was then assessed on these protein levels relative to non-trained SCI controls, plus the effectiveness of a shorter training duration (30 …
Modulation Of The Ovarian Cancer Humoral Response By Tumor-Derived Exosomes., Carolyn Denise Roberson
Modulation Of The Ovarian Cancer Humoral Response By Tumor-Derived Exosomes., Carolyn Denise Roberson
Electronic Theses and Dissertations
The pathogenesis of epithelial ovarian cancer is complicated by its diagnosis during the latter stages of the disease resulting from lack of symptoms or from presence of symptoms that mimic other conditions. Because of the often fatal prognosis by the time of actual detection, efforts are being made to better understand the host immune response to ovarian cancer. In this study, the contributions of the humoral immune response were investigated by focusing on the role of tumor-derived exosomes and their ability to modulate humoral immune responses. First, ovarian cancer patient-derived free circulating antibodies were investigated for immunoreactivity to patient antigen. …
Interactions Between Human Neutrophils And Mycobacterium Smegmatis : A Comparative General Analysis., Irina Miralda
Interactions Between Human Neutrophils And Mycobacterium Smegmatis : A Comparative General Analysis., Irina Miralda
College of Arts & Sciences Senior Honors Theses
Mycobacteria smegmatis is an abundant soil and water inhabitant with which humans are continuously in contact. Despite the fact that it is typically considered non-‐pathogenic, a few rare cases of M. smegmatis-‐caused infections have been reported and it has been shown that M. smegmatis is able to modulate inflammatory responses in macrophages. Neutrophils are the innate immune system’s first line of centralized defense against invading microbes, especially the frequently encountered M. smegmatis. However, very little information is known of the mechanism by which neutrophils eliminate environmental bacteria. In this study, the hypothesis that M. smegmatis regulates neutrophil functional responses, and …
Functional Implications Of Demyelination And The Molecular Control Of Remyelination In The Adult Mouse., Nicholas John Kuypers
Functional Implications Of Demyelination And The Molecular Control Of Remyelination In The Adult Mouse., Nicholas John Kuypers
Electronic Theses and Dissertations
Oligodendrocyte (OL) loss contributes to the functional deficits underlying diseases with a demyelinating component (Gajjar et al., 1997; Miller et al., 2002). Remyelination can restore these deficits (Duncan et al., 2009). Chapter 1 is an introduction to de- and re-myelination thus providing the necessary background information for consideration in subsequent chapters. Ethidium bromide (EB) has been extensively used in the rat and cat as a model of spinal cord demyelination. However, this lesion has not been addressed in the adult mouse. Therefore, Chapters 2 and 3 characterize a model of chronic EB-induced spinal cord demyelination in the mouse which can …
