Analysis Of E2f1 Target Genes Involved In Cell Cycle And Apoptosis, Scott N. Freeman

USF Tampa Graduate Theses and Dissertations

One of the main results of Rb-E2F pathway disruption is deregulation of the E2F family of transcription factors, which can lead to inappropriate proliferation, oncogenic transformation, or the induction of apoptosis. Given the potential negative biological effects associated with deregulated E2F activity, it is of great importance to study E2F targets that mediate these effects. In Part I of this manuscript, we identify the RhoBTB2 putative tumor suppressor gene as a direct physiological target of the E2F1 transcription factor. We find that RhoBTB2 is highly upregulated during mitosis due in part to E2F1, and that overexpression of RhoBTB2 increases the …

Evolutionary Genetics Of The Family Placobranchidae (Mollusca: Gastropoda: Opisthobranchia: Sacoglossa), Anna Lee Bass

USF Tampa Graduate Theses and Dissertations

Members of the family Placobranchidae have been the focus of numerous studies because of their interesting physiological adaptations (kleptochemistry and kleptoplasty) and ecological associations with marine algae. More than 100 species have been described since the 1800's, but no determination of phylogenetic relationships in the family has occurred. DNA sequences from two mitochondrial genes (large subunit ribosomal and cytochrome c oxidase subunit I) and one nuclear gene (Histone 3) were used to reconstruct relationships among 34 nominal species within the Placobranchidae. Strong support for terminal nodes was found using Bayesian phylogenetic methods; however, a "soft" polytomy was detected at internal …

Mapping Tampa Bay Cynoscion Nebulosus Spawning Habitat Using Passive Acoustic Surveys, Sarah Lyle Walters

USF Tampa Graduate Theses and Dissertations

Spotted seatrout, Cynoscion nebulosus, spawning locations as well as associated environmental variables were determined for Tampa Bay, Florida during the 2004 spawning season using a mobile hydrophone survey. Hydrophones, a type of underwater microphone, can be used to detect and record spawning sounds of soniferous fishes. During their spawning season in Tampa Bay which generally occurs between March and September, mature male spotted seatrout generate sounds associated with courtship in the crepuscular and evening periods by vibrating sonic muscles against the swim bladder. Active spawning sites can be located using hydrophones to find these calling males.

Closing The Racial Achievement Gap: The Role Of Reforming Instructional Practices, Harold Wenglinsky

Education Policy Analysis Archives (EPAA)

No Child Left Behind calls for schools to close the achievement gap between races in math and reading. One possible way for schools to do so is to encourage their teachers to engage in practices that disproportionately benefit their minority students. The current study applies the technique of Hierarchical Linear Modeling to a nationally representative sample of 13,000 fourth graders who took the 2000 National Assessment of Educational Progress in mathematics to identify instructional practices that reduce the achievement gap. It finds that, even when taking student background into account, various instructional practices can make a substantial difference.

Perceptions Of Monteverde Youth (14-18 Years Of Age) Towards Pro- And Anti-Tobacco Advertising In Costa Rica, August 2004, Joanne Lee, Sandra Oh, Diana Oliva, Susan Walker, Myriam Scally

Monteverde Institute: Culture, Community, and Health

A study on the youth perceptions of tobacco advertising in the Monteverde region of Costa Rica. Although health risks associated with tobacco use are well documented in the world, tobacco companies continue to seek new smokers to increase sales. As a result, youth have been one of the main targets of tobacco advertising because smokers usually begin smoking in their teen years. This study focused on the youth perceptions of tobacco advertising in the Monteverde region of Costa Rica. Our hypothesis states that while pro-tobacco advertisements attract the attention of youth (between ages 14 and 18 years) to become smokers …

Chemical And Biological Investigation Of The Antarctic Red Alga Delisea Pulchra, Santhisree Nandiraju

USF Tampa Graduate Theses and Dissertations

Our interest in the red alga Delisea pulchra (=D.fimbriata) (Greville) Montagne 1844 (Rhodophyceae, Bonnemaisoniales, Bonnemaisoniaceace) was stimulated by its activity in the biosssays done at Wyeth Pharmaceuticals. Halogenated compounds from D. pulchra interfere with Gram-negative bacterial signaling systems, affect the growth of Gram-positive bacteria, inhibit quorum sensing and swarming motility of marine bacteria (inhibit bacterial communication). They also inhibit surface colonization in marine bacteria and exhibit antifouling properties against barnacle larvae and macroalgal gametes.

Chemical investigation of D.pulchra collected near Palmer Station, Antarctica yielded three new dimeric halogenated furanones, pulchralide A-C (41-43), along with previously reported …

An Introductory Lesson Plan To The Flora And Fauna Of The Monteverde Cloud Forest, December 2003, Amanda Rocklet

Monteverde Institute: Tropical Ecology and Conservation

The result of this project is a mini-course lesson plan which can be used at the Cloud Forest School-Centro de Educación Creativa (C.E.C,). The mini course lesson plan will be used in seventh and eighth grade classes to teach the local taxa of Monteverde. Enclosed are six Power Point presentations, six interactive activity plans, six field guides, and a list of teacher resources. I expect this mini course to reinforce the C.E.C.'s environmental education curriculum while also taking into account teacher turnover and lack of resources.

Spatial Distribution Patterns Of Mistletoe (Antidaphne Viscoidea: Eremolepidaceae, And Phoradendron Undulatum: Viscaceae) On Psidium Guajava (Mrytaceae) In Monteverde, Costa Rica, December 2003, Matthew Greenfield

Monteverde Institute: Tropical Ecology and Conservation

Spatial distributions of mistletoe are noticeably clustered but unexamined in Monteverde, Costa Rica. To better understand their spatial structure, I examined the dispersion of two species of epiphytic mistletoe (Antidaphne viscoidea: Eremolepidaceae and Phoradendron undulatum: Viscaceae) within and between host trees. Six sites on one hill in Cañitas, Costa Rica were surveyed for data relating to dispersion structure (nearest neighbor distance and frequency within host trees). Additional study was done on the spatial dispersion on the host tree Psidium guajava, and it was found to have clustered dispersions. Indices of dispersion and tests comparing observed results to Poisson distributions showed …

N-Thiolated Β-Lactams: Chemistry And Biology Of A Novel Class Of Antimicrobial Agents For Mrsa, Timothy E. Long

USF Tampa Graduate Theses and Dissertations

N-Methylthio beta-lactams represent a promising new family of antibacterial agents whose in vitro activity is confined largely to Staphylococcus species, including multidrug-resistant forms of S. aureus. Originally developed in the 1980's for use as synthetic intermediates, N-methylthio beta-lactams have recently been shown in these laboratories to possess intriguing biological properties which are addressed in Chapters I-IV. In terms of the antibacterial activities, the structural features and species specificities exhibited by these compounds are unlike those of any existing family of beta-lactam drugs. The lactams seem to exert their effects intracellularly, requiring passage of the bioactive species through the …

Function And Size Optimization In Mucuna Urens Vexillum, May 2002, Mark Macedo

Monteverde Institute: Tropical Ecology and Conservation

This study examines the role of the vexillum as an aural nectar guide in the species Mucuna urens. Field manipulations show that the vexillum of M. urens enhances visitation and pollen removal (X2 = 52.8, p<.001). Subsequent observational studies conducted on bat visited hummingbird feeders support this finding as well (X2 = 10.67, p< .005). Data also show an increase in vexillum size correlated with number of bats visits (X2 = 32.06, p < .001). Two explanations are offered for why M. urens and other bat pollinated flowers in the genus have not developed as large a vexillum as possible. Investment return optimization is one possible explanation. Niche partitioning of potential pollinators is another.

Remote Sensing Observations Of Winter Phytoplankton Blooms Southwest Of The Luzon Strait In The South China Sea, Dan-Ling Tang, I-Hsun Ni, Dana R. Kester, Frank E. Muller-Karger

Marine Science Faculty Publications

The Luzon Strait is a channel between the Philippine Sea and the South China Sea. This area is traditionally classified as an oligotrophic zone with low primary productivity. Even so, high concentrations of pigment were detected 100 km southwest of the Strait through analysis of historical Coastal Zone Color Scanner (CZCS) data that the Nimbus-7 satellite collected during the winters of 1979 to 1986. These blooms were observed in December 1979, February 1983, February 1985, and January 1986, when sea surface temperatures measured with the National Oceanic and Atmospheric Administration's (NOAAs) Advanced Very High Resolution Radiometer (AVHRR) were 23 to …
