Effect Of Monounsaturated Fat Rich Almonds On Hemostatic And Inflammatory Factors In Healthy Adults, Kristianne M. Connell

Loma Linda University Electronic Theses, Dissertations & Projects

Background: The frequent consumption of nuts is inversely associated with the incidence of cardiovascular disease. Nuts are known to decrease the risk of cardiovascular disease by reducing serum total and low-density lipoprotein (LDL) cholesterol. Markers of inflammation including C-reactive protein, E-selectin and interleukin-6 have been proposed to be newer risk factors for cardiovascular disease. However, the influence of nuts such as almonds on markers of inflammation and hemostasis that influence cardiovascular disease risk is not currently known.

Objective: The objective of this study was to determine the effect of almond consumption on markers of inflammation and hemostatic factors in healthy …

A Novel Strategy Utilizing Co-Expression Of Murine Il-12 And Antisense Tgf-Pl Against H238 Tumor Formation, Craig A. Seheult

Loma Linda University Electronic Theses, Dissertations & Projects

Cytokines have a profound effect on immune modulation, thus playing a significant role in cancer gene therapy. A variety of human carcinomas secrete transforming growth factor-beta (TGF-β), a cytokine with potent immunosuppressive properties. Suppressing TGF-β could be a key to successfully combating malignancies, such as gliomas, mammary, and colon cancers, that over-express TGF-β. Conversely, interleukin-12 (IL-12) is a potent immunostimulatory cytokine capable of regulating T and NK cell-mediated cytotoxic responses (Trinchieri, 1994) during an anti-tumor response. Activation of the immune system with such immunostimulatory cytokines renders it inert to the suppressive effects of TGF-β. To better understand these processes our …

Cocaine Induces Apoptosis In Coronary Artery Endothelial Cells: Cellular And Molecular Mechanisms, Jiale He

Loma Linda University Electronic Theses, Dissertations & Projects

Cocaine abuse has been associated with numerous cardiovascular consequences, such as depressed myocardial contractility, elevated blood pressure, coronary artery vasoconstriction, and myocardial ischemia and infarction. The multifactorial effects of cocaine often contribute to its sympathomimetic function. However, the direct cytotoxic effects of cocaine on the cardiovascular system, especially vascular endothelium, and the cellular and molecular mechanisms remain unknown. The present study was designed to examine the general hypothesis that cocaine induces apoptosis of coronary artery endothelium by suppressing nitric oxide synthesis, stimulating cytochrome c release from mitochondria and subsequently activation of the caspases cascade, which lead to endothelial cell apoptosis. …

Age Related Changes In Contractile Sensitivity To Cyclic Gmp And Intracellular Calcium Compartmentalization In Ovine Arteries, Surya Margono Nauli

Loma Linda University Electronic Theses, Dissertations & Projects

The study examines the hypothesis that maturation changes the ability of cGMP to produce cerebral vasodilatation and alters the relative intracellular calcium pool sizes in ovine arteries. In ovine basilars taken from near-term fetal and young adult sheep, 8- pCPT-cGMP relaxed potassium- and serotonin-induced tone with pD2 values of 4.4±0.1 and 4.9±0.1 (fetal basilar) and 4.0±0.1 and 4.7±0.1 (adult basilar), respectively. In fura-2 loaded arteries, 8-pCPT-cGMP significantly lowered increases in cytosolic calcium concentration induced by serotonin but not potassium regardless of age. When calcium sensitivity was calculated in the same arteries as the slope of the relation between calcium concentration …

Assessment Of Immune System Involvement In Tourette Syndrome, Ashley Dawn Levine

Loma Linda University Electronic Theses, Dissertations & Projects

Tourette syndrome (TS) is currently hypothesized to be the result of genetic and immunological components. This study investigated whether TS subjects produce IgG and IgA antibodies that bind to caudate nucleus, hippocampus, frontal cortex, cerebellum, thalamus, globus pallidus interior, exterior and putamen. Thirty- two children (14 TS, 7 family control, and 11 non-family control) and thirty-nine adults (11 TS, 14 family control, and 14 non-family control) were studied. Immunofluorescent studies were performed on basal ganglia tissue using serum from TS children and their family members. Brain antigens were prepared as two fractions (supernatant and pellet) and used as targets for …
