Computational Modeling For Abnormal Brain Tissue Segmentation, Brain Tumor Tracking, And Grading, Syed Mohammad Shamin Reza

Electrical & Computer Engineering Theses & Dissertations

This dissertation proposes novel texture feature-based computational models for quantitative analysis of abnormal tissues in two neurological disorders: brain tumor and stroke. Brain tumors are the cells with uncontrolled growth in the brain tissues and one of the major causes of death due to cancer. On the other hand, brain strokes occur due to the sudden interruption of the blood supply which damages the normal brain tissues and frequently causes death or persistent disability. Clinical management of these brain tumors and stroke lesions critically depends on robust quantitative analysis using different imaging modalities including Magnetic Resonance (MR) and Digital Pathology …

Spirituality Within Reach: A Pathway Through Meditation, Serena C. Cyr

Antioch University Dissertations & Theses

Meditation is an ancient spiritual practice that has been demonstrated to be beneficial in reducing chronic pain, substance use, and eating disorders, as well as aiding in the treatment of sleep disorders, cancer, and psychological distress. In an effort to enhance the benefits, many contemporary meditation practices have been secularized, focusing on the cognitive, the psychological, and the emotional components, while de-emphasizing the spiritual aspects of meditation. However, spiritual meditation practices also demonstrate benefits, including stress reduction, improved emotional well being, increases in pain tolerance, reductions in mental health symptoms, and increased faith. However, little is known regarding the effects …

Meta-Regression: Prognostic Models As Objective Predictors Of Mortality Among Icu Cancer Patients, Sheila Donnell

Nursing Theses and Dissertations

Cancer patients admitted to the intensive care unit (ICU) may be experiencing complications of disease or treatment-related effects. While acute complications related to disease and/or its therapeutic management vary in severity, the approach to ICU-centered care is complicated by actual versus perceived risks of poor outcomes. Prognostic models that inform clinical judgment of nurses and physicians may prove helpful in this population. The Acute Physiology and Chronic Health Evaluation II (APACHE II), Simplified Acute Physiology Score II (SAPS II) and Sequential Organ Failure Assessment (SOFA) are ICU-based models predicting 30-day mortality among the general ICU population. Although studies have been …

The Effect Of Long Term Administration Of Glucocorticoid To Bone Lining Cells Apoptosis, Gadis Meinar Sari

Folia Medica Indonesiana

Glucocorticoid is widely used in medical treatment as an immune system or an inflammation therapy. However its long term administration can cause life-threatening side effects. One of them is bone mass loss which increases the risk of bone fractures in the long-term use. Bone lining cells derived from mesenchymal stem cells, which serve as a backup cell bone-forming osteoblasts. Glucocorticoids acting directly on osteoblasts, bone lining cells when reduced due to increased apoptosis, the reserve cells to bone formation will be decreased. The aim of this study was to count the amount of apoptotic bone lining cells after long term …

Body Size Predicts Cardiac And Vascular Resistance Effects On Men's And Women's Blood Pressure, Joyce M. Evans, Siqi Wang, Christopher Greb, Vladimir Kostas, Charles F. Knapp, Qingguang Zhang, Eric S. Roemmele, Michael B. Stenger, David C. Randall

Biomedical Engineering Faculty Publications

Key Points Summary

• We report how blood pressure, cardiac output and vascular resistance are related to height, weight, body surface area (BSA), and body mass index (BMI) in healthy young adults at supine rest and standing.
• Much inter-subject variability in young adult's blood pressure, currently attributed to health status, may actually result from inter-individual body size differences.
• Each cardiovascular variable is linearly related to height, weight and/or BSA (more than to BMI).
• When supine, cardiac output is positively related, while vascular resistance is negatively related, to body size. Upon standing, the change in vascular resistance is positively related to size. …

Evidence Of Youthful Aging: Chronic Stress And The Association With Dna Damage, Jason M. Fly, M. Catherine Desoto

McNair Scholars Program Summer Research Symposium

Abstract: Persistent elevated basal levels of the hormone cortisol are an indication of chronic stress. Maladaptive response to stress, or chronic psychological stress, is thought to play a crucial role in the biological mechanisms involved in mental disorders, disease, and accelerated aging. In 2011, a critical connection was reported between elevated cortisol and the oxidative damage to DNA associated with aging and disease in a study of elderly participants (ages 63-83) via 24-hour urinary samples (Joergensen, et. al., 2011). This connection, if verified, has implications for how stress may accelerate the aging process and the onset of cancer, diabetes, and …

Galen’S Analogy: Animal Experimentation And Anatomy In The Second Century C.E., Annastasia Conner

Anthós

Galen of Pergamum (129 – ca. 216 C.E.) is truly one of the most pivotal characters in the history of medicine, and particularly the field of anatomy. A physician in the ancient Roman Empire, he did not allow his work to be constrained by contemporary boundaries, instead delving further into the field of anatomy and physiology than any doctor had yet done. He built upon the existing work of his predecessors as well as making new discoveries through which he would shape contemporary and future understandings of anatomy, and of medicine as a whole. Although a luminary in his field, …

Characterization Of Filifactor Alocis And Its Immune Evasion Strategies Employed Against Human Neutrophils., Cortney Linn Armstrong

Electronic Theses and Dissertations

Periodontal disease is among the most common of inflammatory conditions and is caused by bacterial and host derived factors. The presence of bacteria drives the recruitment of neutrophils, professional phagocytes, to migrate to specific oral sites where they produce potent antimicrobials to kill their target. However, this inflammation and production of antimicrobials must be strictly regulated to minimize collateral host tissue damage. Human neutrophils recognized the oral pathogen Filifactor alocis through Toll-like receptor (TLR) 2 and upon binding, activated both p38 MAPK and ERK signaling pathways, known to be involved in neutrophil cell migration and degranulation. F. alocis also stimulated …

Metabolic Regulation By Stress Mediators In Fetal Ovine Skeletal Muscle And Adult Bovine Myoblasts, Elena Marie Merrick

Department of Animal Science: Dissertations, Theses, and Student Research

Our objective was to determine the effect of stress mediators such as inflammatory cytokines and β adrenergic agonists on developing skeletal muscle. Fetal sheep exposed to chronic maternal inflammation had decreased skeletal muscle glucose oxidation rates when stimulated with insulin or TNFα. In addition, activation of Akt by insulin was decreased after maternal inflammation when compared to controls and there were not differences in skeletal muscle fiber type ratios between the two treatment groups. This indicates that maternal inflammation does not affect overall oxidative capacity in the developing fetus, but rather insulin signaling pathways are disrupted.

We sought to determine …

What Should The U.S. Army Learn From History? Recovery From A Strategy Deficit, Colin S. Gray Dr.

Books, Monographs & Collaborative Studies

Does history repeat itself? This monograph clearly answers “no,” firmly. However, it does not argue that an absence of repetition in the sense of analogy means that history can have no utility for the soldier today. This monograph argues for a “historical parallelism,” in place of shaky or false analogy. The past, even the distant and ancient past, provides evidence of the potency of lasting virtues of good conduct. This monograph concludes by offering four recommendations: 1) Behave prudently. 2) Remember the concept of the great stream of time. 3) Do not forget that war nearly always is a gamble. …
