Development Of Novel Biomarkers In Cancer: Detection Of Circulating Mir-141 As A Potential Prognostic Marker For Prostate Cancer, Jason Cadaoas Gonzales

UNLV Theses, Dissertations, Professional Papers, and Capstones

Prostate cancer (CAP) is the most common epithelial malignancy and the second leading cause of cancer deaths in American men. The identification of predictive and prognostic biomarkers in CAP patients is critical for improving clinical outcomes. Although the measurement of prostate-specific antigen (PSA) and radiographic studies are clinically approved to predict response to therapy, these tests can oftentimes prove to be inadequate in certain patients. Thus, it is important to discover new biomarkers to improve chances of survivability. We and others have shown that longitudinal measurements of circulating tumor cells (CTC) and lactate dehydrogenase (LDH) may aid in predicting response …

The Crooked Median, Monica Zarazua

UNLV Theses, Dissertations, Professional Papers, and Capstones

Words search. There are specific points designated by written language, where one might stand for just a little while until the satisfaction of a pattern is revealed. In this collection of stories, one of the forces that serves as a catalyst for this search is the outside gaze. The gaze exerts itself onto characters. The characters may or may not be conscious of it, may or may not welcome it, but they must grapple with it. The gaze projects its needs and desires onto the characters. It seeks to control them, and it desires to be viewed with admiration, lowered …

Age And Petrogenesis Of The Roaring Mountain Rhyolites, Yellowstone Volcanic Field, Wyoming, Kathleen Marie Wooton

UNLV Theses, Dissertations, Professional Papers, and Capstones

Extracaldera rhyolites in the Norris-Mammoth Corridor of the Yellowstone Volcanic Field (YVF) appear to be unrelated to intracaldera volcanism, resulting instead from a new crustal magma source derived from northeastward propagation of the Yellowstone “melting anomaly.” The youngest extracaldera rhyolite unit, the Roaring Mountain Member (RM), is chemically distinct from the previous extracaldera lavas, reverting to more primitive compositions.

This study suggests that the majority of the RM rhyolites erupted from the same large-scale silicic magma system. Based on geochemistry and 40Ar/39Ar geochronology, the Crystal Spring mingled rhyolite and Obsidian Cliff rhyolite erupted concurrently at 59.1 ± 2.0 ka. The …

Discrete Diffusion Models To Study The Effects Of Mg2+ Concentration On The Phopq Signal Transduction System, Preetam Ghosh, Samik Ghosh, Kalyan Basu, Sajal K. Das, Chaoyang Zhang

Faculty Publications

Background: The challenge today is to develop a modeling and simulation paradigm that integrates structural, molecular and genetic data for a quantitative understanding of physiology and behavior of biological processes at multiple scales. This modeling method requires techniques that maintain a reasonable accuracy of the biological process and also reduces the computational overhead. This objective motivates the use of new methods that can transform the problem from energy and affinity based modeling to information theory based modeling. To achieve this, we transform all dynamics within the cell into a random event time, which is specified through an information domain …

F5c: A Variant Of Faugere's F5 Algorithm With Reduced Gröbner Bases, Christian Eder, John E. Perry

Faculty Publications

The F5 algorithm for computing Gröbner bases achieves a high level of efficiency through the careful analysis of signatures assigned to each computed polynomial. However, it computes and uses many polynomials that turn out to be redundant. Eliminating these redundant polynomials is a non-trivial task, because they correspond to signatures required for reduction. This paper revisits the theory underlying F5 and describes F5C, a new variant that prunes redundant polynomials, then re-computes signatures to preserve correctness. This strategy successfully reduces both overhead and execution time. (C) 2010 Elsevier Ltd. All rights reserved.
