Detrusor underactivity (DU) increases susceptibility to urinary retention and accordingly further complicates the management of urinary incontinence. Bladder muscle stretch, a lack of estrogen, and aging are 3 notable DU risk factors. The aim of this research is to better characterize the changes in cellular composition of the bladder that result from these 3 risk factors to gain a better understanding of DU pathogenesis and pathobiology. This research focuses on the effects of a lack of estrogen while also providing an outline for determining the effects of bladder muscle stretch and aging on the cellular composition of the bladder.

Phonological development in hearing children of deaf parents Dr. Diane Lillo-Martin 5/9/2010 The researcher wishes to determine the significance of a unique linguistic environment on the effects of phonological development. The research examines whether 3 hearing children of deaf parents, hereafter referred to as CODAs, have inconsistencies, as compared to children in a typical linguistic environment, in their syllable structure, phonological processes or phonemic inventories. More specifically, the research asks whether their speech is more consistent with children of typical environments or more similar to children with phonological delays or disorders or articulation disorders. After the examination of these three components to a child's phonological development, it can be concluded that the linguistic environment of CODA children does not negatively hinder their phonological language development.

Molecular mechanisms that underlie preleukemic myelodysplasia (MDS) and acute myelogenous leukemia (AML) are poorly understood. In MDS or AML with a refractory clinical course, more than 30% of patients have acquired interstitial or complete deletions of chromosome 5. The 5q13.3 chromosomal segment is commonly lost as the result of 5q deletion. Reciprocal and unbalanced translocations of 5q13.3 can also occur as sole anomalies associated with refractory AML or MDS. This study addresses the hypothesis that a critical gene at 5q13.3 functions either as a classical tumor suppressor or as a chromosomal translocation partner and contributes to leukemogenesis. ^ Previous studies from our laboratory delineated a critical region of loss to a 2.5–3.0Mb interval at 5q13.3 between microsatellite markers D5S672 and GATA-P18104. The critical region of loss was later resolved to an interval of approximately 2Mb between the markers D5S672 and D5S2029. I, then generated a long range physical map of yeast artificial chromosomes (YACs) and developed novel sequence tagged sites (STS). To enhance the resolution of this map, bacterial artificial chromosomes (BACs) were used to construct a triply linked contig across a 1 Mb interval. These BACs were used as probes for fluorescent in situ hybridization (FISH) on an AML cell line to define the 5q13.3 critical region. A 200kb BAC, 484a9, spans the translocation breakpoint in this cell line. A novel gene, SSDP2 (single stranded DNA binding protein), is disrupted at the breakpoint because its first four exons are encoded within 140kb of BAC 484a9. This finding suggests that SSDP2 is the critical gene at 5q13.3. ^ In addition, I made an observation that deletions of chromosome 5q13 co-segregate with loss of the chromosome 17p. In some cases the deletions result from unbalanced translocations between 5q13 and 17p13. It was confirmed that the TP53 gene is deleted in patients with 17p loss, and the remaining allele harbors somatic mutation. Thus, the genetic basis for the aggressive clinical course in AML and MDS may be caused by functional cooperation between deletion or disruption of the 5q13.3 critical gene and inactivation of TP53. ^

The purpose of this descriptive cross-sectional survey was to examine the health promotion attitudes and practices of Texas nurse practitioners and to evaluate the applicability of the Theory of Reasoned Action and the Theory of Planned Behavior as a theoretical model to guide nurse practitioner health promotion research. A questionnaire developed to elicit responses regarding demographic information, practice characteristics, behavior, behavior intention, attitudes toward health promotion, subjective norm and perceived behavioral control for health promotion practices was mailed to the home address of 727 Texas nurse practitioners. The majority of the 442 respondents reported positive attitudes toward health promotion. Texas nurse practitioners provide health promotion for more than 50% of their patients. Significant barriers to the provision of health promotion cited by Texas nurse practitioners were lack of time, lack of reimbursement and lack of patient desire to change behavior. The findings of this study support the use of the Theory of Reasoned Action and the Theory of Planned Behavior in nurse practitioner research. ^

This pilot study investigates selected etiquette issues that appear to have arisen with the prevalence of hand-held electronic communications. Researchers surveyed college undergraduates, graduates, and faculty about the appropriateness of multitasking when others are present, whether they thank people with a hand-written note, by telephone, or by email, and the appropriateness of their preferred means of saying thank you. This study raises questions about etiquette issues when using electronic communications.

This paper is part of a five-year research project funded by the National Institute on Disability and Rehabilitation Research (NIDRR) that addresses the health, disability and service needs of Native Americans in eastern tribes. The Participatory Action Research model with a community-based approach was used to facilitate collaboration among the participating tribes. Native American research technicians conducted individual interviews with members of their tribes. Demographics, prevalence of disabilities, and various factors associated with health and mental health are presented. Of the 858 tribal members who responded to survey questions, the third most prominent health problem reported was mental illness.
