GSBS Dissertations and Theses
Sepsis is the leading cause of death among critically ill patients and the 10th most common cause of death overall in the United States. The mortality rates increase with severity of the disease, ranging from 15% for sepsis to 60% for septic shock. Patient with sepsis can present varied clinical symptoms depending on the personal predisposition, causal microorganism, organ system involved, and disease severity. To facilitate sepsis diagnosis, the first sepsis consensus definitions was published in 1991 and then updated in 2001. Early recognition of a sepsis patient followed with timely and appropriate treatment and management strategies have been ...

Novel Amino Acid And Ethanolamine Derivatives As Potential Tumor Imaging Agents For Positron Emission Tomography, 2010 University of Pennsylvania
Novel Amino Acid And Ethanolamine Derivatives As Potential Tumor Imaging Agents For Positron Emission Tomography, Limin Wang
Publicly Accessible Penn Dissertations
Malignant tumors can be detected with high sensitivity and specificity by imaging their increased metabolic rate for glucose, amino acids and fatty acids. Positron emission tomography (PET) with glucose analog [18F]FDG, which utilizes increased glucose metabolism, has become a routine clinical test for diagnosis, staging and restaging a variety of cancers. Despite the tremendous success of PET-FDG, there are some well-known limitations of [18F]FDG such as high cerebral uptake, uptake in inflammatory tissues, high excretion through urinary tract and low or negligent uptake in certain type of tumors. Decades of nuclear medicine research have lead to development of ...

Evaluation Of The Quantitative Accuracy Of A Commercially-Available Positron Emission Mammography Scanner, Adam Springer
UT GSBS Dissertations and Theses (Open Access)
Objective: The PEM Flex Solo II (Naviscan, Inc., San Diego, CA) is currently the only commercially-available positron emission mammography (PEM) scanner. This scanner does not apply corrections for count rate effects, attenuation or scatter during image reconstruction, potentially affecting the quantitative accuracy of images. This work measures the overall quantitative accuracy of the PEM Flex system, and determines the contributions of error due to count rate effects, attenuation and scatter.
Materials and Methods: Gelatin phantoms were designed to simulate breasts of different sizes (4 – 12 cm thick) with varying uniform background activity concentration (0.007 – 0.5 μCi/cc), cysts ...

Influence Of Anchoring On Miscarriage Risk Perception Associated With Amniocentesis, Regina A. Nuccio
UT GSBS Dissertations and Theses (Open Access)
INFLUENCE OF ANCHORING ON MISCARRIAGE RISK PERCEPTION ASSOCIATED WITH AMNIOCENTESIS Publication No. ___________ Regina Nuccio, BS Supervisory Professor: Claire N. Singletary, MS, CGC Amniocentesis is the most common invasive procedure performed during pregnancy (Eddleman, et al., 2006). One important factor that women consider when making a decision about amniocentesis is the risk of miscarriage associated with the procedure. People use heuristics such as anchoring, the action of using a prior belief regarding the magnitude of risk as a frame of reference for new information to be synthesized, to better understand risks that they encounter in their lives. This study aimed ...
Platelet Alpha- And Beta- Secretase Activities Are Not Significantly Affected By Dementia Or Mild Cognitive Impairment In Swedish Patients., 2010 Technological University Dublin
Platelet Alpha- And Beta- Secretase Activities Are Not Significantly Affected By Dementia Or Mild Cognitive Impairment In Swedish Patients., Paul Gorham, Natalie Bark, Steve Meaney, Ingemar Bjorkhem, Milita Crisby
The processing of the Amyloid Precursor Protein (APP) is a critical event in the formation of amyloid plaques which are composed of the 4kDa amyloid beta-peptide (Abeta). Processing of APP occurs through a non-amyloidogenic pathway, mediated by initial alpha-secretase cleavage or through an amyloidogenic pathway via sequential cleavage by beta- and gamma-secretase enzymes, which produces Abeta peptides. Currently, the diagnosis of probable or possible Alzheimer's disease (AD) is primarily based on neuropsychological and neuroradiological assessment. Recent reports indicate that platelet beta-secretase activity is moderately increased in patients with AD and mild cognitive impairment (MCI). To our knowledge platelet alpha-secretase ...

An Optical Machine Vision System For Applications In Cytopathology, Jonathan Blackledge, Dmitry Dubovitskiy
This paper discusses a new approach to the processes of object detection, recognition and classification in a digital image focusing on problem in Cytopathology. A unique self learning procedure is presented in order to incorporate expert knowledge. The classification method is based on the application of a set of features which includes fractal parameters such as the Lacunarity and Fourier dimension. Thus, the approach includes the characterisation of an object in terms of its fractal properties and texture characteristics. The principal issues associated with object recognition are presented which include the basic model and segmentation algorithms. The self-learning procedure for ...

Lost In Translation?: An Essay On Law And Neuroscience, 2010 University of Pennsylvania
Lost In Translation?: An Essay On Law And Neuroscience, Stephen J. Morse
Faculty Scholarship at Penn Law
The rapid expansion in neuroscientific research fuelled by the advent of functional magnetic resonance imaging [fMRI] has been accompanied by popular and scholarly commentary suggesting that neuroscience may substantially alter, and perhaps will even revolutionize, both law and morality. This essay, a contribution to, Law and Neuroscience (M. Freeman, Ed. 2011), will attempt to put such claims in perspective and to consider how properly to think about the relation between law and neuroscience. The overarching thesis is that neuroscience may indeed make some contributions to legal doctrine, practice and theory, but such contributions will be few and modest for the ...
