Regulation Of Steroid Sulfatase In Human Breast Cancer Cells And Screening Of Human Tissues For Steroid Sulfatase Status, Abhinav Chandra
Regulation Of Steroid Sulfatase In Human Breast Cancer Cells And Screening Of Human Tissues For Steroid Sulfatase Status, Abhinav Chandra
Electronic Theses and Dissertations
Breast cancer is the most frequently occurring cancer in women and is the second leading cause of death. About 40% of breast cancers are hormone-dependent and require estrogen for their growth. The steroid sulfatase pathway is an important means of converting local inactive estrogens to their active forms, thus supporting tumor growth. A substantial amount of research has been performed in the design of steroid sulfatase inhibitors, but the regulation of steroid sulfatase has been largely overlooked. My goal was to study the regulation of steroid sulfatase by different steroid hormones, using two human breast cancer cell lines the hormone-dependent …
Statistically Designed Spheronization And Scale-Up Of Ibuprofen Microparticulates Using The Rotor Disk Fluid-Bed Technology: Coating For Prolonged Release And Hard Gelatin Encapsulation Of Microparticulates, Beatrice Chukwumezie
Electronic Theses and Dissertations
The aim was to develop uncoated and coated ibuprofen microparticulates in a one-step fluid-bed machine with rotor-disk insert, for immediate and prolonged drug delivery. Feasibilty studies using ibuprofen: Avicel (RC-581; 50:50), sodium lauryl sulfate (1%) as surfactant and water as binder in FLM-15 Vector Flo-coater with 12" stainless-steel and waffle-disk inserts showed that amount of binder, plate type and the presence of surfactant affected most of spheroid characteristics. These variables were used in a 2x2x3 full factorial (replicated) experiment. Blocking was used to study batch-to-batch reproducibility of the process and product variables. Our results confirmed that the binder amount, plate-type …
Isolation Of Intragenic Suppressor Mutations Of A Dominant-Negative Ftsz Allele, Carla Ciccone
Isolation Of Intragenic Suppressor Mutations Of A Dominant-Negative Ftsz Allele, Carla Ciccone
Electronic Theses and Dissertations
Streptomyces coelicolor, a gram-positive bacterium containing division genes that are dispensable for growth and viability. ftsZ encodes the earliest acting cell division protein in prokaryotes. In S. coelicolor a mutation at codon 275 in ftsZ (ftsZ25), changes an alanine to a valine causing a block in division. Using a homology model of the crystal structure of FtsZ, I hypothesized that changing another amino acid having direct interaction with amino acid 275 might restore function. The structure-directed mutation changed a leucine to a valine at codon 259. The double mutation did not restore division to the organism; this change alone also …

The purpose of this ethnonursing study was to discover the culture care meanings, beliefs, expressions, and practices of urban elderly Puerto Ricans residing in a mid-sized community. The Culture Care Theory was used as the guiding framework in studying the domain of inquiry: the discovery of the meanings and practices of generic care and professional health care of elderly community dwelling Puerto Ricans. The qualitative research method used for this study was the ethnonursing research method. Twelve key informants and twenty-one general informants were interviewed. Four themes were extracted from analysis of the data, and patterns to support the themes …

Feeding Identity: The Critical Hermeneutics Of Contemporary Kleinian Psychoanalytically Oriented Psychotherapy From The Perspective Of A Novice, David M. Greco-Brooks
Electronic Theses and Dissertations
Clinical supervision is required for every graduate student pursuing a clinical track in psychology. Yet empirical research has focused almost exclusively on identifying efficacious supervision techniques in terms of altering "trainee characteristics" rather than investigating in depth the effects of supervision as changes in the characteristics of the trainee's communicative behavior. Moreover, the question of how the specialized communicative behavior practiced by the trainee works to facilitate change for the client/patient has not been addressed by quantitative empirical studies of supervision or psychotherapy process. This study addresses these problems by asking: (1) What characterizes the author's specialized communicative competence after …
The Influence Of Stigma On Help Seeking Attitudes For Depression, Margaret Jordan Halter
The Influence Of Stigma On Help Seeking Attitudes For Depression, Margaret Jordan Halter
Electronic Theses and Dissertations
Major depression is a common, debilitating, and life threatening illness, and its treatment may be hampered by stigma. There have been a limited number of studies that link stigma and help seeking attitudes for depression. The purpose of this descriptive correlational study was to identify the relationship between stigmatizing attitudes and help seeking behavior. Also of interest was the impact of person-level variables that may be associated with a person's desire to seek help. Goffman's Stigma Theory and Weiner's Attribution Theory served as theoretical foundations. Data were collected by questionnaires distributed to patients (N = 117) waiting to be seen …
The Use Of Speech Disfluency As An Indicant Of Paradigm Development In Pharmacy's Academic Subdisciplines, Erin Renee Holmes
The Use Of Speech Disfluency As An Indicant Of Paradigm Development In Pharmacy's Academic Subdisciplines, Erin Renee Holmes
Electronic Theses and Dissertations
This study compared speech disfluency rates within five subdisciplines of pharmacy to estimate their paradigm development, and identified alternative factors associated with differing rates. Rates were observed in randomly selected courses. Lecturers completed a modified version of the Brief Fear of Negative Evaluation survey and a self-rated anxiety measure. Ten percent of recordings were randomly selected for analysis by two judges to determine inter-reliability. An ANCOVA was conducted on the frequency of lecture disfluencies, with the frequency of interview disfluencies serving as the covariate. The overall mean disfluency rate in lectures was 2.11 disfluencies/minute. Average dislfuency rates among the five …
Nitrogen Metabolism In Iron-Respiring Bacteria, Ching (Tony) Lung Hsieh
Nitrogen Metabolism In Iron-Respiring Bacteria, Ching (Tony) Lung Hsieh
Electronic Theses and Dissertations
Nitrogen metabolism was investigated in three species of iron respiring bacteria Geobacter metallireducens, Geobacter sulfurreducens, and Sulfurospirillum barnesii. G. metallireducens and G. sulfurreducens were shown to grow in medium containing N2, NO3-, or NH4 but nitrite inhibited growth. BLAST analysis of the draft genomic sequence of G. metallireducens revealed only Nar, Nrf, and Nif homologues but no assimilatory genes (i.e., Nas). Two nar operons were identified, narCGHJIK1K2, and narCGHI. A putative CAP/CRP recognition binding site was found upstream and two molybdenum biosynthetic genes were found downstream of the large operon. Both operons contain a novel cytochrome c (NarC) that has …
Uncoiling The Gut Of Eleutherodactylus Coqui: Characterization Of The Anatomical Development And Proliferation Pattern, Carrie Elizabeth Langer
Uncoiling The Gut Of Eleutherodactylus Coqui: Characterization Of The Anatomical Development And Proliferation Pattern, Carrie Elizabeth Langer
Electronic Theses and Dissertations
Among the frogs there are two forms of development: biphasic and direct. Xenopus laevis, a biphasic developer, develops from an embryo into a tadpole, and then metamorphoses into an adult frog. Eleutherodactylus coqui is a direct developer, meaning that it lacks a tadpole stage. The embryo develops directly into the adult form. Comparing development between these two frogs provides insight on the evolution of these groups. I present an anatomical description of the gut development of E. coqui, and compare my findings to the development of X. laevis. E. coqui does not have a highly coiled gut like that of …
Regulation Of Vitellogenin And Other Serum Proteins By Estrogen And Xenobiotic Estrogens In Salamanders, Lisa Marie Nespoli
Regulation Of Vitellogenin And Other Serum Proteins By Estrogen And Xenobiotic Estrogens In Salamanders, Lisa Marie Nespoli
Electronic Theses and Dissertations
Environmental estrogens pose potential health risks to humans and wildlife by disrupting physiological and developmental processes; therefore, our laboratory has been designing in vivo bioassays on induction of the egg-yolk precursor protein vitellogenin. I have provided information on vitellogenin induction by estrogens in tiger salamanders (Ambystoma tigrinum), spotted salamanders (Ambystoma maculatum), hellbenders (Cryptobranchus alleganiensis), Morelet's crocodiles (Crocodylus moreletii), and developed vitellogenin immunoassays in these species. Salamanders were estrogen-injected; blood was collected at intervals. Estrogen exposed male salamanders of all species, produced substantial quantities of a 200-kDa protein, the approximate size of vertebrate vitellogenins. Sequencing of estrogen-induced proteins showed substantial homology …

Cloning And Characterization Of A Git1 Homolog Gene From Schizosaccharomyces Pombe, Christi Nolder
Cloning And Characterization Of A Git1 Homolog Gene From Schizosaccharomyces Pombe, Christi Nolder
Electronic Theses and Dissertations
Phosphatidylinositol (PI) deacylation in Saccharomyces cerevisiae results in the formation and excretion of glycerophosphoinositol (GPI). This is a predominant route of PI turnover and is not unique to S. cerevisiae. Released GPI can be transported back into the cell through a membrane permease encoded by the GIT1 gene, Git1p. Maximum transport is achieved in low inositol/low phosphate conditions at pHs below 7, and the addition of a protonophore to the GPI transport assay abolishes transport activity. These findings suggest that Git1p is a proton symporter. An excess of unlabeled glycerol-3-phosphate (G3P) inhibits the transport of radiolabeled GPI into S. cerevisiae. …
Theoretical Aspects Of Designing New Vaccines For Breast Cancer: Docking Studies Of Peptide/Hla-A2.1 Complexes, Tugba Kucukkal
Theoretical Aspects Of Designing New Vaccines For Breast Cancer: Docking Studies Of Peptide/Hla-A2.1 Complexes, Tugba Kucukkal
Electronic Theses and Dissertations
HER2/neu is a transmembrane glycoprotein that is overexpressed in many tumors, including ovarian and breast cancers. The HER2/neu peptide IISAVVGIL (GP2) is recognized by tumor-specific cytotoxic T lymphocytes in the context of human class I major histocompatibility complex (MHC) HLA-A2.1. One limiting-factor for using GP2 as a tumor vaccine is its poor affinity for HLA-A2.1, even though it has the correct peptide-binding motif. The research aims are to develop an accurate docking method for the binding of GP2 to HLA-A2.1, to understand the molecular forces that give rise to strong binding, and to predict mutations that lead to new tumor …
