Evaluating Human Adult Mesenchymal Stem Cells And Mg-63 Cells On Vitoss, Chronos Granulat And Chronos For Use In Bone Tissue Engineering, Hina Qidwai

Electronic Theses and Dissertations

The delivery of human adult mesenchymal stem cells (hAMSC) using bone void fillers is a novel approach for use in bone tissue engineering. The evaluation of hAMSC and osteoblast-like MG-63 cell activity on three β-tricalcium phosphate-based bone void fillers (Vitoss, ChronOS Granulat and ChronOS) has not been carried out. Human osteosarcoma cells (MG-63 cells), as well as hAMSCs, readily seed over 90% of the available biomaterials under static culture conditions, and the attached cells proliferate to extensively cover the biomaterials as seen by DAPI staining and LIVE/DEAD viability staining. The attached cells are over 90% viable after 7 days in …

Knowledge of the successful integration of content reading and inquiry skills by experienced classroom teachers would be useful to many educators as they plan instruction to achieve challenging state and national standards for reading as well as science. The problem was investigated using grounded theory methodology. Open-ended questions were asked in three focus groups and six individual interviews that included teachers from various Florida school districts. …

Analysis Of Specific Cis-Acting Dna Sequences Of The Himar1 Mariner Transposon, Beth Berta

Electronic Theses and Dissertations

Himar1, found in the horn fly Haematobia irritans, belongs to the mariner family of transposable elements. Mariners are a diverse and widespread family of eukaryotic transposons that transpose via a cut-and-paste mechanism. Mariner transposition not only requires the transposase, but also specific cis-acting DNA sequences known as inverted terminal repeats (ITRs). Very little is known about the fine structure of mariner ITRs, particularly which bases are important for transposition. A mariner family ITR sequence logo representing 20 different mariners from six different subfamilies suggests that more conserved regions of the logo are required for transposase binding while the more variable …

The Regulation Of Git1 Transcription In Response To Nutritional Factors, Wei Cheng

Electronic Theses and Dissertations

Glycerophosphoinositol is produced through deacylation of the essential phospholipid phosphatidylinositol. In Saccharomyces cerevisiae, when inositol is limiting in the extracellular environment, the glycerophosphoinositol can be transported into the cell through the permease encoded by GIT1 . In this study, Northern blotting and GIT1 promoter activity were analyzed to assess the nutritional factors responsible for the regulation of GIT1 transcription. Here, I report that GIT1 transcript levels are greater in cells starved for phosphate, with or without inositol limitation, than in cells only limited for inositol. Ino2p and Ino4p are required for full GIT1 expression when the medium lacks both inositol …

Development Of A Biochemical Probe For Arsenate Respiring Bacteria Using Bacillus Selenitireducens Strain Mls10, Mirunalni Thangavelu

Electronic Theses and Dissertations

To date, eighteen phylogenetically diverse prokaryotes have been found to utilize arsenic as the terminal electron acceptor in anaerobic respiration, converting arsenate into the more toxic and mobile arsenite. This process can lead to ground water contamination, making it imperative to detect in situ, active arsenate-respiring prokaryotes.

A biochemical probe that targets the catalytic subunit (ArrA) of the respiratory arsenate reductase (Arr) from Bacillus selenitireducens strain MLS10 was developed. Polyclonal antibodies were raised against a fifteen amino acids long highly conserved sequence at the C-terminus of ArrA. Highly specific antibodies obtained by affinity purification using the synthesized ArrA polypeptide, reacted …

Learning To Be Free: The Print Media Of Cotonou, Benin, Stephen Urbanski

Electronic Theses and Dissertations

Benin, a West African republic of six million people, has had multiple influences shape its cultural and historical landscape, including the French colonization, a multiplicity of dictators, and a 17-year period of Marxism. During the early years of the colonization, the print media was particularly dissident, always advocating an end to the colonization, which greatly disrupted the regions core pan-African values. In 1990, the National Conference heralded a conversion to democracy as well as a boom in the number of privately owned newspapers.

This dissertation addresses at the concept of freedom and how it is defined from both a Western …

Political Scandals And Policy Creation, Keely Peterson

Electronic Theses and Dissertations

This study focuses on political scandal and its effect on public policy creation. Using evidence from the Watergate, Iran Contra, Whitewater and Monica Lewinksy scandal, this study investigates the combined factors of political scandal, media and public opinion. This study hypothesizes a positive relationship between these combined factors and policy creation. In order to test the hypothesized relationship minor scandals were used for comparison throughout the study. Also content analysis, LexisNexis, and publications such as Congressional Quarterly were also used to gather the necessary research. The research shows that four out of the three major scandals researched supported the hypothesized …

Assessment Of Constructs Related To Childhood Aggression, Susan B. Mclaughlin

Electronic Theses and Dissertations

This study provides empirical support for the comprehensive theoretical model of aggression proposed by Meloy (2001) by examining characteristics of children who have a longstanding history of aggression across home and educational settings. The theoretical model first proposed by Meloy (2001) found attachment, anxiety, and attention difficulties in adults who evidenced severe aggression problems. The current study clarified how the adult model applies to children. That is, this study examined how attachment, anxiety, and attention are related to the overall functioning of children requiring treatment for aggression. Results are discussed in terms of child development issues, treatment selection, and intervention …

The Internet And The American Political System, Noah David, Gaar

Electronic Theses and Dissertations

The past eight years have seen a great increase in Internet usage in American culture and politics. It would seem that, in our digital age, the Internet has exercised strong effects on political behavior and even on legislators. This thesis explores the variety and intensity of these effects, finding them to be substantial and growing, although not yet robust. The main influences the net has exerted on American politics take place predominantly within two areas: political campaigns and online political interest groups. Activists are certainly using the Internet for political causes, but this sort of Internet usage is really just …

Female Sexual Offenders-An Underexamined Population, Creaig Anthony Dunton

Electronic Theses and Dissertations

Sex crimes are considered to be among the most damaging and heinous forms of social deviance in existence. Besides the acts perpetrated by the offenders, the social stigma attached to being victimized is often just as injurious to the victim. Society sees males as the sole perpetrators of acts of sexual abuse, but this is not the case. The extant literature shows that women, while fewer in number, also perpetrate acts of sexual abuse and assault against other adults and children. This thesis is a preliminary typology that classifies female sexual offenders based upon the acts perpetrated, using cases presented …

Method For Determination Of Singlet Oxygen Quantum Yields For New Fluorene-Based Photosensitizers In Aqueous Media For The Advancement Of Photodynamic Therapy, Wade William Grabow

Electronic Theses and Dissertations

Photodynamic therapy (PDT) has been investigated over the past three decades and is currently an approved therapeutic modality for skin cancer, the treatment of superficial bladder, early lung and advanced esophageal cancers, and age-related macular degeneration in a number of countries. In PDT, the absorption of light by a chromophore generates cytotoxic species such as reactive singlet oxygen, leading to irreversible destruction of the treated tissue. The measurement of the singlet oxygen quantum yield is an important determinant used to evaluate the efficiency of new photodynamic therapy agents developed in the laboratory, to screen potential photosensitizers in aqueous media.The singlet …

Chemical Structure - Nonlinear Optical Property Relationships For A Series Of Two-Photon Absorbing Fluorene Molecules, Joel Mccajah Hales

Electronic Theses and Dissertations

This dissertation reports on the investigation of two-photon absorption (2PA) in a series of fluorenyl molecules. Several current and emerging technologies exploit this optical nonlinearity including two-photon fluorescence imaging, three-dimensional microfabrication, site-specific photodynamic cancer therapy and biological caging studies. The two key features of this nonlinearity which make it an ideal candidate for the above applications are its quadratic dependence on the incident irradiance and the improved penetration into absorbing media that it affords. As a consequence of the burgeoning field which exploits 2PA, it is a goal to find materials that exhibit strong two-photon absorbing capabilities. Organic materials are …

Facade Democracy: Democratic Transition In Kazakhstan And Uzbekistan, Robin Nicole Merritt

Electronic Theses and Dissertations

This thesis explores the reasons behind the stagnation in the transition to democracy in Kazakhstan and Uzbekistan. According to their constitutions, Kazakhstan and Uzbekistan are democracies. In actuality, however, there is little evidence to support that these are democratic systems. These states' post-Soviet constitutions outline them as democracies - yet they lack a free press; freedom of association is suppressed; religious freedom is limited; and free speech is constrained as well. While these two countries hold popular elections, much of their electoral processes are under the control of the executive branch of government - calling into question whether or not …
