The Reckless Pursuit Of Dominion: A Situational Analysis Of The Nba And Diminishing Player Autonomy, Michael Mccann Jan 2006

The Reckless Pursuit Of Dominion: A Situational Analysis Of The Nba And Diminishing Player Autonomy, Michael Mccann

Law Faculty Scholarship

This Article examines required genetic testing of NBA players from a situational vantage point, integrating socio-psychological, legal, and ethical analyses. The core argument may be expressed as follows: required genetic testing of NBA players appears consistent with a broader and largely deleterious agenda by the NBA to control players. Since implementation of the rookie wage scale in 1995 through the recent imposition of a paternalistic player dress code, the NBA has increasingly usurped player autonomy. The NBA's capacity to do so largely rests in its adroit manipulation of the situational influences that influence fans and media. For instance, because of …

Investigation Of Cell Surface Phenotypes At Mucosal Sites In Response To Murine Cytomegalovirus Infection, Mary Esther Bruorton Jan 2006

Investigation Of Cell Surface Phenotypes At Mucosal Sites In Response To Murine Cytomegalovirus Infection, Mary Esther Bruorton

MUSC Theses and Dissertations

The salivary gland is the predominant effector site of mucosal immune responses in the oral cavity. In mice, the salivary glands are known to receive immune lymphocytes stimulated in inductive sites such as the gut- and nasal-associated lymphoid tissues, thus, allowing the production of antigen-specific antibodies in saliva. However, the potential of the salivary gland as a mucosal inductive site has not been fully explored. In order to investigate this concept, we have developed a model resulting in a focused salivary gland infection using intraglandular delivery of tissue culture-derived murine cytomegalovirus (tcMCMV). Utilizing this route of infection, we were capable …

Effect Of A Paediatric Incentive Spacer And Reinforcement Of Inhalation Technique Training In Preschool Children, Jasminka Murdzoska Jan 2006

Effect Of A Paediatric Incentive Spacer And Reinforcement Of Inhalation Technique Training In Preschool Children, Jasminka Murdzoska

Theses : Honours

Incorrect inhaled drug delivery technique is a common problem in paediatric asthma [1-4]. Previously, device technique training has been shown to significantly improve inhaler skills, using subjective methods, namely check-list analysis [5-8]. However, more objective measures are needed to examine more comprehensively the effect of training in preschool children and parents. Resistance to regular asthma therapy is also a frequent problem when attempting to treat young children. Reasoning with young children can be very difficult and parents often have to struggle with their child to achieve compliance [2]. The Funhaler spacer (FH) (Funhaler™; InfaMed, Australia) has been developed in an …

Understanding The Nature Of Surgical Excellence Using A Competency Modeling Approach, Hope S. Hanner-Bailey Jan 2006

Understanding The Nature Of Surgical Excellence Using A Competency Modeling Approach, Hope S. Hanner-Bailey

Psychology Theses & Dissertations

Currently, a thorough description of the knowledge, skills, abilities, and other personal characteristics (KSAOs) that distinguish an exceptional surgeon does not exist. This knowledge is pertinent to the development of selection, training, and performance assessment methods that can be used to develop high performing surgeons. Expert surgeons from around the country were recruited to participate in an interview to discuss the KSAOs (i.e., the competencies) needed to be exceptional in the field. A smaller number of novice surgeons were also interviewed. The expert interview data were distilled into a competency model that consists of ten competencies and patterns within the …

Background: Breast cancer is the most common cancer among women in both the developed and the developing world. The incidence of breast cancer in Karachi, Pakistan is 69.1 per 100,000 with breast cancer presentation in stages III and IV being common (>or= 50%). The most pragmatic solution to early detection lies in breast cancer education of women. Nurses constitute a special group having characteristics most suited for disseminating breast cancer information to the women. We assessed the level of knowledge of breast cancer risk factors among registered female nurses in teaching hospitals of Karachi. We also identified whether selected …


Relationship Between Antipyretic Effects And Cytokine Levels In Uncomplicated Falciparum Malaria During Different Treatment Regimes, Elisabeth Hugosson, Scott M. Montgomery, Zul Premji, Marita Troye-Blomberg, Anders Bjorkman Jan 2006

Relationship Between Antipyretic Effects And Cytokine Levels In Uncomplicated Falciparum Malaria During Different Treatment Regimes, Elisabeth Hugosson, Scott M. Montgomery, Zul Premji, Marita Troye-Blomberg, Anders Bjorkman

Pathology, East Africa

We have previously shown that both chloroquine and paracetamol (acetaminophen) have antipyretic activity during treatment of acute uncomplicated Plasmodium falciparum malaria in children 1-4 years old. Here, we studied if this effect was accompanied by changes in plasma cytokine levels. The 104 children were treated with either chloroquine or sulfadoxine/pyrimethamine (SP) alone, SP + chloroquine or SP + paracetamol for 4 days. Cytokine levels were determined days 0, 2 and 3, body temperature every sixth hour until 72 h and parasitemia once daily for 4 days. At admission, body temperature correlated with levels of IL-10, IFN-γ and IL-6, and parasitemia …

3,3′-Diindolylmethane And Paclitaxel Act Synergistically To Promote Apoptosis In Her2/Neu Human Breast Cancer Cells, Kandace P. Mcguire, N. Ngoubilly, M. Neavyn, Susan Lanza-Jacoby

Department of Surgery Faculty Papers

Background. HER2/neu positive breast tumors are difficult to treat. About 25 to 30% of invasive breast tumors overexpress the HER2/neu oncogene. These tumors are aggressive and become resistant to chemotherapeutic drugs. 3,3′-diindolylmethane (DIM), the active metabolite of indole-3-carbinol, a naturally occurring compound found in cruciferous vegetables, has been found to have anti-cancer properties in both humans and animals. DIM has been shown to induce cell cycle arrest and apoptosis in animal breast cancer models. Because HER2/neu overexpression confers resistance to paclitaxel, and DIM has anti-tumor effects, we hypothesized that DIM will enhance the cytotoxic effects of paclitaxel, a common …

Obstetrics and Gynaecology, East Africa

Background: The microbiological diagnosis of bacterial vaginosis is usually made using Nugent's criteria, a useful but rather laborious scoring system based on counting bacterial cell types on Gram stained slides of vaginal smears. Ison and Hay have simplified the score system to three categories and added a fourth category for microflora with a predominance of the Streptococcus cell type. Because in the Nugent system several cell types are not taken into account for a final score, we carried out a detailed assessment of the composition of the vaginal microflora in relation to standard Gram stain in order the improve the …

Chromosomal Localization Of The Islet Neogenesis Associated Protein (Ingap) Gene In Syrian Hamster By Tyramide Signal Amplification-Fluorescence In Situ Hybridization (Tsa-Fish), Sallie A. Smith

Biological Sciences Theses & Dissertations

Diabetes mellitus is a group of conditions characterized by hyperglycemia due to an inability to produce or properly utilize insulin. The majority of cases fall into two categories, Type I and Type 2. Type I results from the autoimmune destruction of pancreatic β-cells of the islets. The beta cells are the exclusive source of insulin and the patient becomes entirely dependent on exogenous insulin to survive. Patients with Type 2 are distinguished by insulin resistance, a condition that develops due to the inability of the body to effectively use the insulin being produced. The β-cells gradually lose their ability to …


The Implications Of “Pay-For-Performance” Reimbursement For Otolaryngology – Head And Neck Surgery, David M. Cognetti, David Reiter Sep 2005

The Implications Of “Pay-For-Performance” Reimbursement For Otolaryngology – Head And Neck Surgery, David M. Cognetti, David Reiter

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

Objective: To introduce otolaryngologists to outcomes-linked reimbursement ("pay-for-performance"), identify clinical practice implications and recommend changes for successful transition from the traditional "pay-for-effort" reimbursement model. Study design: Policy review Results: Payers are actively linking reimbursement to quality. Since the Institute of Medicine issued its report on medical errors in 1999, there has been much public and private concern over patient safety. In an effort to base health care payment on quality, "pay-for-performance" programs reward or penalize hospitals and physicians for their ability to maintain standards of care established by payers and regulatory groups. More than 100 such programs are operational in …

Tcpf Is A Soluble Colonization Factor And Protective Antigen Secreted By El Tor And Classical O1 And O139 Vibrio Cholerae Serogroups, Thomas J. Kirn, Ronald K. Taylor Aug 2005

Tcpf Is A Soluble Colonization Factor And Protective Antigen Secreted By El Tor And Classical O1 And O139 Vibrio Cholerae Serogroups, Thomas J. Kirn, Ronald K. Taylor

Dartmouth Scholarship

Vibrio cholerae causes diarrhea by colonizing the human small bowel and intoxicating epithelial cells. Colonization is a required step in pathogenesis, and strains defective for colonization are significantly attenuated. The best-characterized V. cholerae colonization factor is the toxin-coregulated pilus (TCP). It has been demonstrated that TCP is required for V. cholerae colonization in both humans and mice. TCP enhances bacterial interactions that allow microcolony formation and thereby promotes survival in the intestine. We have recently discovered that the TCP biogenesis apparatus also serves as a secretion system, mediating the terminal step in the extracellular secretion pathway of TcpF. TcpF was …
