Malignancy In Oral Lichen Planus: A Review Of A Group From The Malaysian Population, Wei Cheong Ngeow

Research Publications (2000 to 2005)

The objective of this study was to determine the socio-demography (age, race and gender) of a group of Malaysian patients who were diagnosed as suffering from oral lichen planus (OLP). The occurrence of malignancy was also investigated. A total of 77 clinical and biopsy records of patients with OLP were studied. Females were affected more than males, with the female to male ratio being 2:1. Middle-aged Indian and Chinese females tend to be affected by OLP when compared with the rest of the population. Only 19 patients returned for further follow-up. One adult Indian female with a six-year history of …

Mamluk Female Patronage, Nanis Nabil Hanna

Archived Theses and Dissertations

This thesis is discussing the topic of Mamliik Female Patronage in Egypt and how it differed from its contemporaries in Jerusalem, Seljuq Anatolia, and Timurid Iran. This subject, however, has not attracted the attention of many scholars, probably, because the information provided by the chronicles and biographers oqhe Mamliik period is scattered and incidental. This is also related to the age-long assumption that women had neither the economic resources nor the legal standing to commission works of art or buildings. The scholars who approached this topic were dealing with the subject from an architectural point of view and not in …

Child, Parent, And Peer Predictors Of Early-Onset Substance Use: A Multisite Longitudinal Study, Julie B Kaplow, Patrick J Curran, Kenneth A Dodge

Faculty, Staff and Students Publications

The purpose of this study was to identify kindergarten-age predictors of early-onset substance use from demographic, environmental, parenting, child psychological, behavioral, and social functioning domains. Data from a longitudinal study of 295 children were gathered using multiple-assessment methods and multiple informants in kindergarten and 1st grade. Annual assessments at ages 10, 11, and 12 reflected that 21% of children reported having initiated substance use by age 12. Results from longitudinal logistic regression models indicated that risk factors at kindergarten include being male, having a parent who abused substances, lower levels of parental verbal reasoning, higher levels of overactivity, more thought …

Improved Continuation Rate Of Depot-Medroxyprogesterone Acetate In Adolescent Mothers, Hatim A. Omar, Amy Fowler, Sandy D'Angelo

Pediatrics Faculty Publications

Poor compliance and high discontinuation rates of Depot-Medroxyprogesterone Acetate (DMPA) and other contraceptive methods are major factors in the continuing problem of adolescent pregnancy. In this study we attempted to determine if providing comprehensive health care for teen mothers and their babies would improve continuation rates of DMPA. Patients who started DMPA between 1/1/96 and 1/1/99 were included. Teen mothers and their babies received all their health care in this clinic, supported by State funding. Key elements regarding DMPA in this clinic were continuity of care, phone and mail reminders of appointments, free DMPA for patients without insurance, counseling at …

Neural Systems For Visual Orienting And Their Relationships To Spatial Working Memory, Maurizio Corbetta, J. Michelle Kincade, Gordon Shulman

Open Access Publications

We investigated neural correlates of human visual orienting using event-related functional magnetic resonance imaging (fMRI). When subjects voluntarily directed attention to a peripheral location, we recorded robust and sustained signals uniquely from the intraparietal sulcus (IPs) and superior frontal cortex (near the frontal eye field, FEF). In the ventral IPs and FEF only, the blood oxygen level dependent signal was modulated by the direction of attention. The IPs and FEF also maintained the most sustained level of activation during a 7-sec delay, when subjects maintained attention at the peripheral cued location (working memory). Therefore, the IPs and FEF form a …

Breast Cancer On The World Wide Web: Cross Sectional Survey Of Quality Of Information And Popularity Of Websites, Funda Meric, Elmer V Bernstam, Nadeem Q Mirza, Kelly K Hunt, Frederick C Ames, Merrick I Ross, Henry M Kuerer, Raphael E Pollock, Mark A Musen, S Eva Singletary

Faculty, Staff and Student Publications

OBJECTIVES: To determine the characteristics of popular breast cancer related websites and whether more popular sites are of higher quality.

DESIGN: The search engine Google was used to generate a list of websites about breast cancer. Google ranks search results by measures of link popularity---the number of links to a site from other sites. The top 200 sites returned in response to the query "breast cancer" were divided into "more popular" and "less popular" subgroups by three different measures of link popularity: Google rank and number of links reported independently by Google and by AltaVista (another search engine).

Reduction In The Incidence Of Type 2 Diabetes With Lifestyle Intervention Or Metformin., William C. Knowler, Elizabeth Barrett-Connor, Sarah E. Fowler, Richard F. Hamman, John M. Lachin, Elizabeth A. Walker, David M. Nathan, P. G. Watson, J. T. Mendoza, K. A. Smith, J. Caro, B. Goldstein, C. Lark, L. Menefee, L. Murphy, C. Pepe, J. M. Spandorfer

Department of Medicine Faculty Papers

BACKGROUND: Type 2 diabetes affects approximately 8 percent of adults in the United States. Some risk factors--elevated plasma glucose concentrations in the fasting state and after an oral glucose load, overweight, and a sedentary lifestyle--are potentially reversible. We hypothesized that modifying these factors with a lifestyle-intervention program or the administration of metformin would prevent or delay the development of diabetes.

METHODS: We randomly assigned 3234 nondiabetic persons with elevated fasting and post-load plasma glucose concentrations to placebo, metformin (850 mg twice daily), or a lifestyle-modification program with the goals of at least a 7 percent weight loss and at least …

Spectral And Temporal Processing In Human Auditory Cortex, Deborah A Hall, Ingrid Johnsrude, Mark P Haggard, Alan R Palmer, Michael A Akeroyd, A Quentin Summerfield

Brain and Mind Institute Researchers' Publications

Hierarchical processing suggests that spectrally and temporally complex stimuli will evoke more activation than do simple stimuli, particularly in non-primary auditory fields. This hypothesis was tested using two tones, a single frequency tone and a harmonic tone, that were either static or frequency modulated to create four stimuli. We interpret the location of differences in activation by drawing comparisons between fMRI and human cytoarchitectonic data, reported in the same brain space. Harmonic tones produced more activation than single tones in right Heschl's gyrus (HG) and bilaterally in the lateral supratemporal plane (STP). Activation was also greater to frequency-modulated tones than …

Associations Between Water-Treatment Methods And Diarrhoea In Hiv-Positive Individuals, J. N. S. Eisenberg, T. J. Wade, A. Hubbard, D. I. Abrams, R. J. Leiser, S. Charles, M. Vu, S. Saha, C. C. Wright, Deborah A. Levy, P. Jensen, J. M. Colford

Journal Articles: Epidemiology

This manuscript extends our previously published work (based on data from one clinic) on the association between three drinking water-treatment modalities (boiling, filtering, and bottling) and diarrhoeal disease in HIV-positive persons by incorporating data from two additional clinics collected in the following year. We conducted a cross-sectional survey of drinking water patterns, medication usage, and episodes of diarrhoea among HIV-positive persons attending clinics associated with the San Francisco Community Consortium. We present combined results from our previously published work in one clinic (n = 226) with data from these two additional clinics (n = 458). In this combined analysis we …

Participant Blinding And Gastrointestinal Illness In A Randomized, Controlled Trial Of An In-Home Drinking Water Intervention, John M. Colford, Judy R. Rees, Timothy J. Wade, Asheena Khalakdina, Joan F. Hilton, Isaac J. Ergas, Susan Burns, Anne Benker, Catherine Ma, Cliff Bowen, Daniel C. Mills, Duc J. Vugia, Dennis D. Juranek, Deborah A. Levy

Journal Articles: Epidemiology

We conducted a randomized, triple-blinded home drinking water intervention trial to determine if a large study could be undertaken while successfully blinding participants. Households were randomized 50:50 to use externally identical active or sham treatment devices. We measured the effectiveness of blinding of participants by using a published blinding index in which values >0.5 indicate successful blinding. The principal health outcome measured was "highly credible gastrointestinal illness" (HCGI). Participants (n=236) from 77 households were successfully blinded to their treatment assignment. At the end of the study, the blinding index was 0.64 (95% confidence interval 0.51-0.78). There were 103 episodes of …

Adolescent Pregnancy Attitudinal Survey, Amy Katherine Wolfe

Theses and Dissertations

A census of 53 adolescent females was conducted over a period of time beginning July 15, 2001 and ending March 5, 2002. Each subject was surveyed by using an interview with 66 items. The resources examined in this census were means of transportation and the social support structure before the female became an adolescent. The census found that 72 percent (N=53) of the adolescent females interviewed do not have a car, and 79 percent do not use public transportation. The census also found that 77 percent of the adolescent females interviewed do depend on their family/friends for transportation, and eighty-five …

Sexually Dimorphic Behavioral Responses To Prenatal Dioxin Exposure, Rieko Hojo, Sander Stern, Grazyna Zareba, Vincent P. Markowski, Christopher Cox, James T. Kost, Bernard Weiss

Psychology

Pregnant Sprague-Dawley rats received a single oral dose of 0, 20, 60, or 180 ng/kg 2,3,7,8-tetrachlorodibenzo-p-dioxin on day 8 of gestation. Each litter contributed a single male-female pair trained to press a lever to obtain food pellets under two operant behavior procedures. Initially, each lever press was reinforced. The fixed-ratio (FR) requirement was then increased every four sessions from the initial setting of 1 to values between 6 and 71. We then studied responses for 30 days under a multiple schedule combining FR 11 and another schedule requiring a pause of at least 10 sec between responses (DRL 10-sec). TCDD …

Female Victims Of Domestic Violence And Their Negotiation For Safety, Lisa Rose Kopinski

UNLV Retrospective Theses & Dissertations

With the majority of studies focusing on the reasons why victims discontinue legal action against their abusers, I believe these women are once again being blamed for the continued abuse. It is my thesis that victims of domestic violence enter formal action against their abusers with specific goals in mind particular to each woman's life situation. These goals may be very different than the legal outcomes prominent amongst our nation's courtrooms. I will attempt to illustrate those goals victims routinely seek as well as the obstacles they encounter when attempting to free themselves from violence. This research will become a …

Gambling With Virtue: The Moral Ramifications Of Female Gaming In The Early Novels Of Frances Burney, Heather Lynn Lusty

UNLV Retrospective Theses & Dissertations

Gambling has always been an influential factor in literature; the importance of gaming to social entertainment in the eighteenth-century is inextricable from both historical and literary studies of the period. In the novel, gaming functions as a tangible social vice; the financial perils and moral recriminations suffered by literary characters is an essential part of their personal development; Frances Burney uses gaming as a fundamental element in her early novels; the trials her heroines experience during their forays into society all include the presence of gaming in some form. The proximity of gaming, as well as the social and moral …

A Descriptive Multiple Case Study Of Caucasian Female Suicide Attempters: Risk And Protective Factors, Janice Johnson Browne

Suicide is a problem globally and in the United States. Suicide rates for youth have remained particularly high. Caucasian men complete more suicidal acts than women, but women are more frequent suicide attempters. To gain information about the phenomenon of female suicide attempting, it is important to study the attempter. Awareness of risk and protective factors is necessary to intervene and prevent future incidences of suicide and suicide attempting.

Methodology

For this research a descriptive case study design was utilized. Three suicide attempters who had attempted suicide one or more times in the past was the sample population for …

Nipple Aspirate Cytology And Pathologic Parameters Predict Residual Cancer And Nodal Involvement After Excisional Breast Biopsy., E R Sauter, H Ehya, A Mammen, G Klein

Department of Surgery Faculty Papers

We previously demonstrated that abnormal nipple aspirate fluid (NAF) cytology predicted residual breast cancer (RC) and tumour size after excisional biopsy (EB), although normal NAF cytology did not exclude RC. Tumour size correlates with the risk of lymph node (LN) metastases. LN metastases provide prognostic information allowing medical and radiation oncologists to determine the need for adjuvant therapy. We hypothesized that pathologic factors known after EB, combined with NAF cytology, would predict with a high degree of accuracy the presence of RC and LN spread. NAF cytology and pathologic parameters: tumour distance from biopsy margins, multifocal and multicentric disease, sub-type …

Evaluation Of Cholera Vaccines Formulated With Toxin-Coregulated Pilin Peptide Plus Polymer Adjuvant In Mice, Jia-Yan Wu, William F. Wade, Ronald K. Taylor

Dartmouth Scholarship

Cholera is an acute diarrheal disease that is caused by the gram-negative bacterium Vibrio cholerae. The low efficacy of currently available killed-whole-cell vaccines and the reactinogenicity coupled with potential reversion of live vaccines have thus far precluded widespread vaccination for the control of cholera. Recent studies on the molecular nature of the virulence components that contribute to V. cholerae pathogenesis have provided insights into possible approaches for the development of a defined subunit cholera vaccine. Genetic analysis has demonstrated that the toxin-coregulated pilus (TCP) is the major factor that contributes to colonization of the human intestine by V. cholerae. In …

Tractor Driving Among Kentucky Farm Youth: Results From The Farm Family Health And Hazard Surveillance Project, Steven R. Browning, Susan C. Westneat, Raeanne Szeluga

Epidemiology and Environmental Health Faculty Publications

This article documents the extent of children's involvement in tractor operations among a representative sample of Kentucky children living and working on family farms. Specifically, we describe children's exposures to tractor-related work activities, profile their use of the tractor (number of days worked), and assess compliance with generally recommended safety measures, such as using tractors equipped with ROPS (rollover protective structures), avoiding riding as passengers on tractors, and operating tractors on public roadways. Data for this study were collected in 1994 and 1995 as part of the NIOSH-sponsored Farm Family Health and Hazard Surveillance Project (FFHHSP). Despite recognition in the …

Spirituality In Late Adulthood, Lisa M. Heintz, Imants Barušs

Psychology

MacDonald's Expressions of Spirituality Inventory was used to examine spirituality in late adulthood using a sample of 30 people (22 women, 8 men) whose mean age was 72.6 yr. While average scores are higher on scales measuring spiritual and religious beliefs and practices for the sample than for a standardization group of undergraduate students with a mean age of 21.0 yr., means are lower on scales measuring paranormal beliefs. Low scores on death anxiety are correlated only with Existential Well-being and age. And, while some religious behaviors such as frequent religious practice, prayer, and church attendance are correlated with some …

Juvenile Females Who Sexually Offend: A Beginning Typology, Jason M. Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was broken into two sections, the first being a comprehensive meta-analysis describing a profile of the juvenile female who sexually offends. The second section was the collection of data of juvenile females who sexually offend in the State of Utah. After the data were collected, a profile was described and compared to that found in the Review of the Literature and a typology was presented.

Ecosystemic legacies were shown to be passed down from one generation to the next. The juveniles were found to come from highly chaotic homes, and subject to maltreatment. Diagnostically, they show symptoms of …

Altered Operant Responding For Motor Reinforcement And The Determination Of Benchmark Doses Following Perinatal Exposure To Low-Level 2,3,7,8-Tetrachlorodibenzo-P-Dioxin, Vincent P. Markowski, Grazyna Zareba, Sander Stern, Christopher Cox, Bernard Weiss

Psychology

Pregnant Holtzman rats were exposed to a single oral dose of 0, 20, 60, or 180 ng/kg 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) on the 18th day of gestation. Their adult female offspring were trained to respond on a lever for brief opportunities to run in specially designed running wheels. Once they had begun responding on a fixed-ratio 1 (FR1) schedule of reinforcement, the fixed-ratio requirement for lever pressing was increased at five-session intervals to values of FR2, FR5, FR10, FR20, and FR30. We examined vaginal cytology after each behavior session to track estrous cyclicity. Under each of the FR values, perinatal TCDD exposure …

A Descriptive Study Of Positive Body Image Among Female Adolescent Dancers, Amy Bobo Courrier

UNLV Retrospective Theses & Dissertations

This study examined whether groups of adolescent girls, who society defines as having a positive body image, actually feel positive about their own body image and how they express it culturally. Cheerleaders and dancers were chosen as accessible groups that embodied the ideal body image as defined by popular Western teen culture. Qualitative analysis was conducted using interviews, observations, and focus groups to determine how these groups felt about their body image and how they defined a positive image. The influence of attitudes towards perfectionism, perceived control over the body, and the desire to follow "healthy" habits all contributed to …

Children Of Alcoholics: An Update., D Z Lieberman

Psychiatry and Behavioral Sciences Faculty Publications

One of four children in the United States lives in a family in which the child is exposed to alcoholism. Children of alcoholics (COAs) are two to ten times more likely to develop alcoholism than non-COAs. This paper reviews studies that have attempted to identify risk factors that mediate the increased vulnerability and the protective factors that moderate the risk. Factors discussed include parental antisocial personality disorder, externalizing behavior, internalizing symptoms, differential response to the effects of alcohol, and positive and negative alcohol-related expectancies. The heterogeneous nature of COAs is emphasized, and some of the challenges related to treatment and …

Ubinuclein, A Novel Nuclear Protein Interacting With Cellular And Viral Transcription Factors., S Aho, M Buisson, T Pajunen, Y W Ryoo, J F Giot, H Gruffat, A Sergeant, Jouni Uitto

Department of Dermatology and Cutaneous Biology Faculty Papers

The major target tissues for Epstein-Barr virus (EBV) infection are B lymphocytes and epithelial cells of the oropharyngeal zone. The product of the EBV BZLF1 early gene, EB1, a member of the basic leucine-zipper family of transcription factors, interacts with both viral and cellular promoters and transcription factors, modulating the reactivation of latent EBV infection. Here, we characterize a novel cellular protein interacting with the basic domains of EB1 and c-Jun, and competing of their binding to the AP1 consensus site. The transcript is present in a wide variety of human adult, fetal, and tumor tissues, and the protein is …

The Pl(A2) Polymorphism Of Integrin Beta(3) Enhances Outside-In Signaling And Adhesive Functions., K Vinod Vijayan, Pascal J. Goldschmidt-Clermont, Christine Roos, Paul F. Bray

Cardeza Foundation for Hematologic Research

Genetic factors are believed to influence the development of arterial thromboses. Because integrin alpha(IIb)beta(3) plays a crucial role in thrombus formation, we analyzed receptor adhesive properties using Chinese hamster ovary and human kidney embryonal 293 cells overexpressing the Pl(A1) or Pl(A2) polymorphic forms of alpha(IIb)beta(3). Soluble fibrinogen binding was no different between Pl(A1) and Pl(A2) cells, either in a resting state or when alpha(IIb)beta(3) was activated with anti-LIBS6. Pl(A1) and Pl(A2) cells bound equivalently to immobilized fibronectin. In contrast, significantly more Pl(A2) cells bound to immobilized fibrinogen in an alpha(IIb)beta(3)-dependent manner than did Pl(A1) cells. Disruption of the actin cytoskeleton …

Sulfa Or Sulfone Prophylaxis And Geographic Region Predict Mutations In The Pneumocystis Carinii Dihydropteroate Synthase Gene, Laurence Huang, Charles B. Beard, Jennifer Creasman, Deborah A. Levy, Jeffrey S. Duchin, Sherline Lee, Norman Pieniazek, Jane L. Carter, Carlos Del Rio, David Rimland, Thomas R. Navin

Journal Articles: Epidemiology

To determine factors associated with mutations in the Pneumocystis carinii dihydropteroate synthase (DHPS) gene, a prospective study of human immunodeficiency virus (HIV)-infected patients with confirmed P. carinii pneumonia was conducted in Atlanta, Seattle, and San Francisco. Clinical information was obtained from patient interview and chart abstraction. DHPS genotype was determined from DNA sequencing. Overall, 76 (68.5%) of 111 patients had a mutant DHPS genotype, including 22 (81.5%) of 27 patients from San Francisco. In multivariate analysis, sulfa or sulfone prophylaxis and study site were independent predictors of a mutant genotype. Fourteen (53.8%) of 26 patients who were newly diagnosed with …

The Emotional Modulation Of Cognitive Processing: An Fmri Study, Joseph Simpson, Dost Ongür, Erbil Akbudak, Thomas Conturo, John Ollinger, Abraham Snyder, Debra Gusnard, Marcus Raichle

Open Access Publications

The functional neuroanatomy of visual processing of surface features of emotionally valenced pictorial stimuli was examined in normal human subjects using functional magnetic resonance imaging (fMRI). Pictorial stimuli were of two types: emotionally negative and neutral pictures. Task performance was slower for the negatively valenced than for the neutral pictures. Significant blood oxygen level dependent (BOLD) increases occurred in the medial and dorsolateral prefrontal cortex, midbrain, substantia innominata, and/or amygdala, and in the posterior cortical visual areas for both stimulus types. Increases were greater for the negatively valenced stimuli. While there was a small but significant BOLD decrease in the …

Intimate Partner Violence Among Men And Women In South Carolina, 1998, Ann L. Coker, Christina Derrick, Julia L. Lumpkin, Robert Oldendick, R H. Potter

CRVAW Faculty Journal Articles

Few studies provide population-based estimates of intimate partner violence (IPV) for men and women, especially at the state level. IPV may result in adverse health effects for victims and perpetrators (1-3). To estimate the lifetime incidence of IPV by type of violence (e.g., physical, sexual, and perceived emotional abuse) and to explore demographic correlates of reporting IPV among men and women, the South Carolina Department of Health and Environmental Control and the University of South Carolina conducted a population-based random-digit-dialed telephone survey of adults in the state. This report summarizes the results of the survey, which indicated that approximately 25% …

Research Publications (2000 to 2005)

One of the objectives of this short communication was to add to the literature on the prevalence of oral recurrent aphthous stomatitis (ORAS). This research is based on a total of 11,697 randomly selected Malaysian subjects with an age range of 25-115 years and a mean age of 44.5 +/- 13.9 years who were examined for oral mucosal lesions (ORAS). The prevalence of ORAS detected during the oral examination (average point prevalence) was found to be 0.5 (64 subjects). ORAS formed 5.7 of all lesions detected during the survey. The average point prevalence of ORAS was highest in the indigenous …

Physiology And Reproduction: Plasma 17Β-Estradiol Levels And Ovarian Interstitial Cell Structure In Embryonic Japanese Quail, M. A. Abdelnabi, M. R. Bakst, J. E. Woods, M. A. Ottinger

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Plasma concentrations of 17β-estradiol (E₂) and left ovarian histology were investigated by light and electron microscopy in female Japanese quail from Day 10 of embryonic development through Day 7, posthatch. Plasma E₂ levels remained relatively constant (102 to 140 pg/mL) in the embryo followed by a sharp decrease posthatch (47 to 70 pg/mL).

Beginning on Day 10 of incubation, cells in the medullary portion (medullary cell; MC) of the left ovaries exhibited ultrastructural evidence of steroidogenic capability. The MC had numerous lipid droplets in close proximity to the smooth endoplasmic reticulum (SER). Mitochondria were also …
