Extracellular Matrix Based Substrates For Propagation Of Human Pluripotent Stem Cells, Sheena Abraham

Theses and Dissertations

In human pluripotent stem cell (hPSC) research and applications, the need for a culture system devoid of non-human components is crucial. Such a system should exhibit characteristics observed in conventional culture systems that have used mouse embryonic fibroblast feeders for hPSC self renewal without the requirement of excessive supplementation with growth factors. To achieve this, we focused on the identification and characterization of extracellular matrix (ECM) substrates for hPSC propagation. ECM substrates derived from mouse and human fibroblasts were assessed for their ability to support self-renewal of hPSCs. Characterization of hPSCs on ECM-based substrates demonstrated maintenance of pluripotent characteristics based …

The Effect Of Color Congruency And Involvement On Non-Profit Organizational Messaging, Claire Selius

USF Tampa Graduate Theses and Dissertations

Color is a major factor in persuasive communication and messaging. This study examines the role of color and other variables in the communication of environmental causes. Many environmental organizations are starting to use color to generate awareness and create symbolic color associations. Based on the congruency theory and the elaboration likelihood model, this study tested specific research hypotheses pertaining to the effects of color-cause congruency and involvement with the cause on consumer reactions through a controlled experiment. Results reveal that involvement and the congruency between color and cause had an effect on attitude toward the organization and attitude toward the …

Priming Expectancies: Effects On Neurophysiological Indices Of Expectancy Violations And Drinking Behavior, Tyler Brumback

USF Tampa Graduate Theses and Dissertations

Investigations of the anticipated effects of alcohol indicate that cognitive frameworks are highly correlated with drinking and other variables associated with alcohol use, explaining up to 50% of the variance in drinking outcomes (Goldman, Darkes, & Del Boca, 1999; Goldman, 2002; Goldman et al., 2006; Goldman, Reich, & Darkes, 2006). Furthermore, alcohol expectancies appear to mediate the relationship between a variety of risk factors, such as sensation seeking, and alcohol outcomes (Darkes, Greenbaum, & Goldman, 2004). The current study examined the relationship of these cognitive networks with a physiological index of expectancy violation

Participants were presented with statements reflecting a …

Acat1 Gene Ablation Increases 24(S)-Hydroxycholesterol Content In The Brain And Ameliorates Amyloid Pathology In Mice With Ad, Elena Y. Bryleva, Maximillian A. Rogers, Catherine C. Y. Chang, Floyd Buen

Dartmouth Scholarship

Cholesterol metabolism has been implicated in the pathogenesis of several neurodegenerative diseases, including the abnormal accumulation of amyloid-beta, one of the pathological hallmarks of Alzheimer disease (AD). Acyl-CoA:cholesterol acyltransferases (ACAT1 and ACAT2) are two enzymes that convert free cholesterol to cholesteryl esters. ACAT inhibitors have recently emerged as promising drug candidates for AD therapy. However, how ACAT inhibitors act in the brain has so far remained unclear. Here we show that ACAT1 is the major functional isoenzyme in the mouse brain. ACAT1 gene ablation (A1-) in triple transgenic (i.e., 3XTg-AD) mice leads to more than 60% reduction in full-length human …

Role Of Jak/Stat Pathway In The Pathogenesis Of Breast Cancer, Qifang Zhang

Theses and Dissertations

The Jak/Stat signaling cascade mediates cell proliferation, differentiation, survival, apoptosis and immune responses. Aberrant activation of this pathway mediates neoplastic transformation and abnormal growth of many malignancies including breast cancer, the most common cancer among women, and the second leading cause of cancer deaths in women in United States. The mechanism by which the Jak/Stat pathway modulates the pathogenesis of breast cancer is unclear. This dissertation elucidates roles of Jak/Stat members that mediate the pathogenesis of breast cancer. For these studies, we used 4T1 mouse mammary tumor cells as a model which mimics human breast cancer. First, we investigated the …

Water-Soluble Soa From Alkene Ozonolysis: Composition And Droplet Activation Kinetics Inferences From Analysis Of Ccn Activity, A. Asa-Awuku, A. Nenes, Song Gao, R. C. Flagan, John H. Seinfeld

Chemistry and Physics Faculty Articles

Cloud formation characteristics of the water-soluble organic fraction (WSOC) of secondary organic aerosol (SOA) formed from the ozonolysis of alkene hydrocarbons (terpinolene, 1-methlycycloheptene and cycloheptene) are studied. Based on size-resolved measurements of CCN activity (of the pure and salted WSOC samples) we estimate the average molar volume and surface tension depression associated with the WSOC using Köhler Theory Analysis (KTA). Consistent with known speciation, the results suggest that the WSOC are composed of low molecular weight species, with an effective molar mass below 200 g mol−1. The water-soluble carbon is also surface-active, depressing surface tension 10–15% from that of pure …

Age, Growth And Maturation Of Swordtip Squid (Photololigo Edulis) In The Southern East China Sea, Kae-Yih Wang, Kuo-Tien Lee, Cheng-Hsin Liao

Journal of Marine Science and Technology–Taiwan

The reproductive biology, and age and growth of the swordtip squid (Photololigo edulis) in the East China Sea were examined based on the growth ring of statoliths from 1797 specimens during the period of November 2002 to November 2004. The maximum age observed was 261 days in female and 253 days in male, an evidence showing that swordtip squid has a longevity of about 9 months in both sexes. Growth in mantle length (ML) and body weight (BW) in both sexes was best described by the exponential model. There was significantly difference in somatic or statolith growth between the sexes. …

Passive Immunity To White Spot Syndrome Virus (Wssv) In Penaeus Monodon Treated With Monoclonal Antibodies Of The Heterologously Produced Vp28 Viral Envelope Protein, Jyh-Yih Chen, Kumarasamy Anbarasu, Chin-Yu Chen, Ying-Chuan Lee, Fan-Hua Nan, Ching-Ming Kuo

Journal of Marine Science and Technology–Taiwan

White spot syndrome virus (WSSV) is a highly pathogenic and prevalent virus affecting shrimp culture worldwide including Taiwan. In the present study, the viral envelope protein, VP28, gene of the WSSV was cloned into a pET28a expression vector. VP28 was expressed as a protein with a 6-histidine tag in Escherichia coli and purified by a Ni-NTA column. Antiserum was raised against this recombinant VP28 protein in BALB/C mice, and it recognized the VP28 protein in purified virions and recombinant proteins. The antiserum was mixed with arginine (100 ppm), lysine (168 ppm), and phenylalanine (88 ppm), and the titer of the …

Perspectives Of Underwater Optics In Biological Oceanography And Plankton Ecology Studies, Hans-Uwe Dahms, Jiang-Shiou Hwang

Journal of Marine Science and Technology–Taiwan

The ever expanding fields of UW (underwater) optics cover principal measurements of the optical properties of the sea, development of new methods of monitoring optical properties, techniques for measurements of organisms or structures in the sea and the development and application of optical instrumentation. In this respect, ocean optics is a multidisciplinary (and multinational) endeavour of science and engineering. Ocean optics has applications in the study of upwelling irradiance and chlorophyll concentrations in the ocean, in the penetration of solar radiation in shallow shelf seas and how this influences temperature profiles and ultimately its effect on sound propagation. Recent development …

Oxygen Regulates The Effective Diffusion Distance Of Nitric Oxide In The Aortic Wall, Xiaoping Liu, Parthasarathy Srinivasan, Eric Collard, Paula Grajdeanu, Kevin Lok, Sarah E. Boyle, Avner Friedman, Jay L. Zweier

Mathematics and Statistics Faculty Publications

Endothelium-derived nitric oxide (NO) is critical in maintaining vascular tone. Accumulating evidence shows that NO bioavailability is regulated by oxygen concentration. However, it is unclear to what extent the oxygen concentration regulates NO bioavailability in the vascular wall. In this study, a recently developed experimental setup was used to measure the NO diffusion flux across the aortic wall at various oxygen concentrations. It was observed that for a constant NO concentration at the endothelial surface, the measured NO diffusion flux out of the adventitial surface at [O2] = 0 μM is around fivefold greater than at [O2] = 150 μM, …

Strategies For Recruitment And Retention Of Secondary Teachers In Central U.S. Rural Schools, Andrea D. Beesley, Kim Atwill, Pamela Blair, Zoe A. Barley

The Rural Educator

This study sought to identify differences in strategies used for teacher recruitment and retention by successful and non-successful rural high schools. According to data from the 2003-2004 Schools and Staffing Survey (SASS), small towns and rural areas in the central U.S. states did have relatively more difficuly in recruiting teachers than did larger communities. However, when the successful and unsuccessful school districts were compared on the strategies and benefits included in the SASS, the only difference was with signing bonuses, which were offered significantly more often in the unsuccessful group than the successful group. The researchers also interviewed seven principals …

Antioxidant And Immune-Stimulating Activities Of Hot-Water Extract From Seaweed Sargassum Hemiphyllum, Pai-An Hwang, Chwen-Herng Wu, Shu-Yun Gau, Shih-Yung Chien, Deng-Fwu Hwang

Journal of Marine Science and Technology–Taiwan

The hot-water extract of seaweed Sargassum hemiphyllum was evaluated antioxidant activity by using four different methods, including DPPH free radicals scavenging activity, Fe+2 chelating activity, superoxide anion radical scavenging activity and reducing power, and the immune-stimulating activity by using HB4C5 cells and J774.1 cells. It was found that the antioxidant activity was increasing in correlating with the concentration below 3.5 mg/ml. The HB4C5 cells showed the maximum relative activities of cell proliferation (174%) and IgM secretion (132%) at 120 µg/ml of hot-water extract. Overheating slightly reduced the immune-stimulating activity of hot-water extract. At 80 µg/ml, J774.1 cells showed the maximum …

Deficient Cd40-Traf6 Signaling In Leukocytes Prevents Atherosclerosis By Skewing The Immune Response Toward An Antiinflammatory Profile, Esther Lutgens, Dirk Lievens, Linda Beckers, Erwin Wijnands, Oliver Soehnlein, Alma Zernecke, Tom Seijkens, David Engel, Jack Cleutjens, Anna M. Keller, Shalin H. Naike, Louis Boon, Hafid Ait Oufella, Ziad Mallat, Cory L. Ahonen, Randolph J. Noelle, Menno P. De Winther, Mat J. Daemen, Erik A. Biessen, Christian Weber

Dartmouth Scholarship

The CD40–CD40 ligand (CD40L) signaling axis plays an important role in immunological pathways. Consequently, this dyad is involved in chronic inflammatory diseases, including atherosclerosis. Inhibition of CD40L in apolipoprotein E (Apoe)–deficient ( Apoe - / - ) mice not only reduced atherosclerosis but also conferred a clinically favorable plaque phenotype that was low in inflammation and high in fibrosis. Blockade of CD40L may not be therapeutically feasible, as long-term inhibition will compromise systemic immune responses. Conceivably, more targeted intervention strategies in CD40 signaling will have less deleterious side effects. We report that deficiency in hematopoietic CD40 reduces atherosclerosis and induces …

Using Questioning To Facilitate Discussion Of Science Teaching Problems In Teacher Professional Development, Meilan Zhang, Mary Lundeberg, Tom J. Mcconnell, Matthew J. Koehler, Jan Eberhardt

Interdisciplinary Journal of Problem-Based Learning

Previous research has shown that questioning is a key strategy that facilitators use to promote discussion in Problem-Based Learning (PBL). Yet, there is a lack of detailed understanding on what questions facilitators ask and how those questions affect discussion. In this study we examined different types of questions that experienced facilitators asked to promote discussion of teaching problems in professional development for science teachers. We videotaped six PBL sessions facilitated by three pairs of experienced facilitators. Data analysis showed that facilitators asked a set of questions to initiate and advance PBL discourse, including questions to solicit ideas, to reframe ideas, …
