Members of the evolutionarily conserved Mastermind (MAM) protein family, including the three related mammalian Mastermind-like (MAML) proteins MAML1-3, function as crucial coactivators of Notch-mediated transcriptional activation. Given the recent evidence of cross-talk between the p53 and Notch signal transduction pathways, we have investigated whether MAML1 may also be a transcriptional coactivator of p53. Indeed, we show here that MAML1 is able to interact with p53. We show that MAML1-p53 interaction involves the N-terminal region of MAML1 and the DNA-binding domain of p53, and we use a chromatin immunoprecipitation assay to show that MAML1 is part of the activator complex that …

Development Of A Decision Support Tool To Facilitate Primary Care Management Of Patients With Abnormal Liver Function Tests Without Clinically Apparent Liver Disease [Hta03/38/02]. Abnormal Liver Function Investigations Evaluation (Alfie), Peter T. Donnan, David Mclernon, Douglas Steinke, Stephen Ryder, Paul Roderick, Frank M. Sullivan, William Rosenberg, John F. Dillon

Pharmacy Practice and Science Faculty Publications

BACKGROUND: Liver function tests (LFTs) are routinely performed in primary care, and are often the gateway to further invasive and/or expensive investigations. Little is known of the consequences in people with an initial abnormal liver function (ALF) test in primary care and with no obvious liver disease. Further investigations may be dangerous for the patient and expensive for Health Services. The aims of this study are to determine the natural history of abnormalities in LFTs before overt liver disease presents in the population and identify those who require minimal further investigations with the potential for reduction in NHS costs.

Values Of Sleep/Wake, Activity/Rest, Circadian Rhythms, And Fatigue Prior To Adjuvant Breast Cancer Chemotherapy., Ann M. Berger, Lynne A. Farr, Brett R. Kuhn, Patricia Fischer, Sangeeta Agrawal

Journal Articles: College of Nursing

Fatigue is the most prevalent and distressing symptom experienced by patients receiving adjuvant chemotherapy for early stage breast cancer. Higher fatigue levels have been related to sleep maintenance problems and low daytime activity in patients who have received chemotherapy, but knowledge describing these relationships prior to chemotherapy is sparse. The Piper Integrated Fatigue Model guided this study, which describes sleep/wake, activity/rest, circadian rhythms, and fatigue and how they interrelate in women with Stage I, II, or IIIA breast cancer during the 48 hours prior to the first adjuvant chemotherapy treatment. The present report describes these variables in 130 females, mean …

Clinical Implication Of Genome-Wide Profiling In Diffuse Large B-Cell Lymphoma And Other Subtypes Of B-Cell Lymphoma., Javeed Iqbal, Shantaram Joshi, Kavita N. Patel, Sofi I. Javed, Can Kucuk, Afeera Aabida, Francesco D'Amore, Kai Fu

Journal Articles: Pathology and Microbiology

The differentiation of lymphoid cells is tightly regulated by transcription factors at various stages during their development. During the maturation processes, different genomic alterations or aberrations such as chromosomal translocation, mutation and deletions may occur that can eventually result in distinct biological and clinical tumors. The different differentiation stages create heterogeneity in lymphoid malignancies, which can complicate the diagnosis. The initial diagnostic scheme for lymphoid diseases was coined by Rappaport followed by Revised European and American Classification of Lymphoid Neoplasms (REAL) and World Health Organization (WHO) classifications. These classification methods were based on histological, immunophenotypic and cytogenetic markers and widely …

Stability Of Negative Self-Structures: A Longitudinal Comparison Of Depressed, Remitted, And Nonpsychiatric Controls., David J A Dozois

Psychology Publications

To be considered a vulnerability marker for depression, a variable should, in addition to demonstrating sensitivity and specificity, also show evidence of temporal stability (i.e., remain present in the absence of depressive symptomatology). Although many cognitive factors are associated with depression, the majority of them appear to be episode rather than vulnerability markers. This study examined cognitive organization of positive and negative interpersonal and achievement content in clinically depressed, remitted, and nonpsychiatric controls. At initial assessment, a sample of 54 clinically depressed individuals and 37 never-depressed controls completed self-report measures of positive and negative automatic thoughts and two cognitive organizational …

Stress And Emotion Classification Using Jitter And Shimmer Features, Xi Li, Jidong Tao, Michael T. Johnson, Joseph Soltis, Anne Savage, Kirsten Leong, John D. Newman

Dr. Dolittle Project: A Framework for Classification and Understanding of Animal Vocalizations

In this paper, we evaluate the use of appended jitter and shimmer speech features for the classification of human speaking styles and of animal vocalization arousal levels. Jitter and shimmer features are extracted from the fundamental frequency contour and added to baseline spectral features, specifically Mel-frequency cepstral coefficients (MFCCs) for human speech and Greenwood function cepstral coefficients (GFCCs) for animal vocalizations. Hidden Markov models (HMMs) with Gaussian mixture models (GMMs) state distributions are used for classification. The appended jitter and shimmer features result in an increase in classification accuracy for several illustrative datasets, including the SUSAS dataset for human speaking …

The State Of The Art In Evaluating The Performance Of Department Chairs And Division Heads., David G. Dunning, Timothy M. Durham, Mert N. Aksu, Brian M. Lange

Journal Articles: College of Dentistry

This study explores the little understood process of evaluating the performance of department chairs/division heads in dental schools. Specifically, this research aimed to elucidate the methods, processes, and outcomes related to the job performance of department chairs/division heads. Forty-three deans and 306 chairs completed surveys with both close-ended and open-ended questions. In addition, ten deans and ten chairs were interviewed. Results indicate that 80 to 90 percent of department chairs are formally evaluated, although as many as 50 percent may lack job descriptions. Recommended best practices for performance appraisal--such as having at least yearly appraisals, holding face-to-face meetings, and setting …

Kollins, Desiree W. Murray, Hima Ravi, Laurence L. Greenhill, Lisa A. Kotler, Natalya Paykina, Patricia Biggins, Julie Stoner

Journal Articles: Psychiatry

OBJECTIVE: The purpose of this study was to assess the effectiveness and tolerability of atomoxetine during acute treatment of attention-deficit/hyperactivity disorder (ADHD) in 5 and 6 year olds.

METHOD: Twenty two children (male n = 19, 86%) with ADHD were treated with atomoxetine for 8 weeks in a three-site, open-label pilot study. Dosing was flexible, with titration to a maximum of 1.8 mg/kg per day. Parent education on behavior management was provided as part of each pharmacotherapy visit.

RESULTS: Subjects demonstrated a mean decrease of 20.68 points (SD = 12.80, p < 0.001)) on the ADHD Rating Scale-IV (ADHD-IV-RS) total score, 10.18 (SD = 7.48, p < 0.001) on the inattentive subscale and 10.50 (SD = 7.04, p < 0.001) on the hyperactive/impulsive subscale. Clinical Global Impression-Severity (CGI-S) was improved in 82% of the children (95% CI, 66-98%) and Children's Global Assessment (CGAS) scores improved 18.91 points on average (SD = 12.20, p < 0.001). The mean final dose of atomoxetine was 1.25 mg/kg per day (SD = 0.35 mg/kg per day). Mood lability was the most commonly reported adverse event (n = 12, 54.5%). Eleven subjects (50%) reported decreased appetite and a mean weight loss of 1.04 kg (SD = 0.80 kg) (p < 0.001) was observed for the group. Vital sign changes were mild and not clinically significant. There were no discontinuations due to adverse events or lack of efficacy.

CONCLUSION: Atomoxetine was generally effective for reducing core ADHD …

Ambulatory Care Adverse Events And Preventable Adverse Events Leading To A Hospital Admission, Donna M Woods, Eric J Thomas, Jane L Holl, Kevin B Weiss, Troyen A Brennan

Faculty, Staff and Student Publications

BACKGROUND: Most healthcare in the US is delivered in the ambulatory care setting, but the epidemiology of errors and adverse events in ambulatory care is understudied.

METHODS: Using the population-based data from the Colorado and Utah Medical Practices Study, we identified adverse events that occurred in an ambulatory care setting and led to hospital admission. Proportions with 95% CIs are reported.

RESULTS: We reviewed 14,700-hospital discharge records and found 587 adverse events of which 70 were ambulatory care adverse events (AAEs) and 31 were ambulatory care preventable adverse events (APAEs). When weighted to the general population, there were 2608 AAEs …

An Essential Role Of Human Ada3 In P53 Acetylation., Alo Nag, Aleksandra Germaniuk-Kurowska, Manjari Dimri, Michael A. Sassack, Channabasavaiah B. Gurumurthy, Qingshen Gao, Goberdhan Dimri, Hamid Band, Vimla Band

Journal Articles: Biochemistry & Molecular Biology

The p53 tumor suppressor protein functions as a critical component of genotoxic stress response by regulating the expression of effector gene products that control the fate of a cell following DNA damage. Unstressed cells maintain p53 at low levels through regulated degradation, and p53 levels and activity are rapidly elevated upon genotoxic stress. Biochemical mechanisms that control the levels and activity of p53 are therefore of great interest. We and others have recently identified hAda3 (human homologue of yeast alteration/deficiency in activation 3) as a p53-interacting protein and enhancer of p53 activity. Here, we show that endogenous levels of p53 …

Adrb2 Arg16gly Polymorphism, Lung Function, And Mortality: Results From The Atherosclerosis Risk In Communities Study, Jill M. Ferdinands, David M. Mannino, Marta L. Gwinn, Molly S. Bray

Internal Medicine Faculty Publications

BACKGROUND: Growing evidence suggests that the Arg16Arg genotype of the beta-2 adrenergic receptor gene may be associated with adverse effects of beta-agonist therapy. We sought to examine the association of beta-agonist use and the Arg16Gly polymorphism with lung function and mortality among participants in the Atherosclerosis Risk in Communities study.

METHODOLOGY AND PRINCIPAL FINDINGS: We genotyped study participants and analyzed the association of the Arg16Gly polymorphism and beta-agonist use with lung function at baseline and clinical examination three years later and with all-cause mortality during 10 years of follow-up. Lung function was characterized by percent-predicted forced expiratory volume in 1 …

A Pure Population Of Lung Alveolar Epithelial Type Ii Cells Derived From Human Embryonic Stem Cells, Dachun Wang, David L Haviland, Alan R Burns, Eva Zsigmond, Rick A Wetsel

Faculty, Staff and Student Publications

Alveolar epithelial type II (ATII) cells are small, cuboidal cells that constitute approximately 60% of the pulmonary alveolar epithelium. These cells are crucial for repair of the injured alveolus by differentiating into alveolar epithelial type I cells. ATII cells derived from human ES (hES) cells are a promising source of cells that could be used therapeutically to treat distal lung diseases. We have developed a reliable transfection and culture procedure, which facilitates, via genetic selection, the differentiation of hES cells into an essentially pure (>99%) population of ATII cells (hES-ATII). Purity, as well as biological features and morphological characteristics …

Sociodemographic Characteristics And Diabetes Predict Invalid Self-Reported Non-Smoking In A Population-Based Study Of U.S. Adults, Monica A. Fisher, George W. Taylor, Brent J. Shelton, Sara M. Debanne

Markey Cancer Center Faculty Publications

BACKGROUND: Nearly all studies reporting smoking status collect self-reported data. The objective of this study was to assess sociodemographic characteristics and selected, common smoking-related diseases as predictors of invalid reporting of non-smoking. Valid self-reported smoking may be related to the degree to which smoking is a behavior that is not tolerated by the smoker's social group.

METHODS: True smoking was defined as having serum cotinine of 15+ng/ml. 1483 "true" smokers 45+ years of age with self-reported smoking and serum cotinine data from the Mobile Examination Center were identified in the third National Health and Nutrition Examination Survey. Invalid non-smoking was …

Phase I And Phase Ii Ocular Metabolic Activities And The Role Of Metabolism In Ophthalmic Prodrug And Codrug Design And Delivery, Abeer M. Al-Ghananeem, Peter A. Crooks

Pharmaceutical Sciences Faculty Publications

While the mammalian eye is seldom considered an organ of drug metabolism, the capacity for biotransformation is present. Compared to the liver, the metabolic capabilities of the eye are minuscule; however, phase I and phase II metabolic activities have been detected in various ocular structures. The careful consideration of ocular tissue metabolic processes within the eye has important implications for controlling the detoxification of therapeutic agents and for providing the potential for site-specific bio-activation of certain drug molecules, thus enabling significant improvements in drug efficacy and the minimization of side-effect from either local or systemic drug delivery to the eye. …

Transgenic Cyclin E Triggers Dysplasia And Multiple Pulmonary Adenocarcinomas, Yan Ma, Steven Fiering, Candice Black, Xi Liu, Ziqiang Yuan, Vincent A. Memoli, David J. Robbins, Heather A. Bentley, Gregory J. Tsongalis, Eugene Demidenko, Sarah J. Freemantle, Ethan Dmitrovsky

Dartmouth Scholarship

Cyclin E is a critical G(1)-S cell cycle regulator aberrantly expressed in bronchial premalignancy and lung cancer. Cyclin E expression negatively affects lung cancer prognosis. Its role in lung carcinogenesis was explored. Retroviral cyclin E transduction promoted pulmonary epithelial cell growth, and small interfering RNA targeting of cyclin E repressed this growth. Murine transgenic lines were engineered to mimic aberrant cyclin E expression in the lung. Wild-type and proteasome degradation-resistant human cyclin E transgenic lines were independently driven by the human surfactant C (SP-C) promoter. Chromosome instability (CIN), pulmonary dysplasia, sonic hedgehog (Shh) pathway activation, adenocarcinomas, and metastases occurred. Notably, …

Oocyte Cytoplasmic Maturation: A Key Mediator Of Oocyte And Embryo Developmental Competence., A J Watson

Obstetrics & Gynaecology Publications

Efforts have intensified to successfully mature and inseminate oocytes in vitro and then culture ensuing embryos to transferable stages from a large number of mammalian species. Success varies, but generally even for the most successful species it is only possible to obtain a maximum of a 40 to 50% development of zygotes to the blastocyst stage. Reduced oocyte developmental competence is suggested as a primary reason for the reduced potential of in vitro-produced embryos. The vast majority of in vitro-matured oocytes are meiotically competent; however, many do not attain an optimal oocyte diameter before insemination. Variations in oocyte in vitro …

Colon Carcinoma Cells Harboring Pik3ca Mutations Display Resistance To Growth Factor Deprivation Induced Apoptosis., J. Wang, Karen Kuropatwinski, Jennie Hauser, Michael R. Rossi, Yunfei Zhou, Alexis Conway, Julie L.C. Kan, Neil W. Gibson, James K.V. Willson, John K. Cowell, Michael G. Brattain

Journal Articles: Eppley Institute

PIK3CA, encoding the p110alpha catalytic subunit of phosphatidylinositol 3-kinase (PI3K), is mutated in a variety of human cancers. We screened the colon cancer cell lines previously established in our laboratory for PIK3CA mutations and found that four of them harbored gain of function mutations. We have now compared a panel of mutant and wild-type cell lines for cell proliferation and survival in response to stress. There was little difference in PI3K activity between mutant PIK3CA-bearing cells (mutant cells) and wild-type PIK3CA-bearing cells (wild-type cells) under optimal growth conditions. However, the mutant cells showed constitutive PI3K activity during growth factor deprivation …

Cell Fate Determination Factor Dach1 Inhibits C-Jun-Induced Contact-Independent Growth, Kongming Wu, Manran Liu, Anping Li, Howard Donninger, Mahadev Rao, Xuanmao Jiao, Michael P. Lisanti, Ales Cvekl, Michael Birrer, Richard G. Pestell

Department of Cancer Biology Faculty Papers

The cell fate determination factor DACH1 plays a key role in cellular differentiation in metazoans. DACH1 is engaged in multiple context-dependent complexes that activate or repress transcription. DACH1 can be recruited to DNA via the Six1/Eya bipartite transcription (DNA binding/coactivator) complex. c-Jun is a critical component of the activator protein (AP)-1 transcription factor complex and can promote contact-independent growth. Herein, DACH1 inhibited c-Jun-induced DNA synthesis and cellular proliferation. Excision of c-Jun with Cre recombinase, in c-jun(f1/f1) 3T3 cells, abrogated DACH1-mediated inhibition of DNA synthesis. c-Jun expression rescued DACH1-mediated inhibition of cellular proliferation. DACH1 inhibited induction of c-Jun by physiological stimuli …

Association Of The Tensin N-Terminal Protein-Tyrosine Phosphatase Domain With The Alpha Isoform Of Protein Phosphatase-1 In Focal Adhesions, Masumi Eto, Jason Kirkbride, Elizabeth Elliott, Su Hao Lo, David L. Brautigan

Department of Molecular Physiology and Biophysics Faculty Papers

Focal adhesions attach cultured cells to the extracellular matrix, and we found endogenous protein phosphatase-1alpha isoform (PP1alpha) localized in adhesions across the entire area of adherent fibroblasts. However, in fibroblasts migrating into a scrape wound or spreading after replating PP1alpha did not appear in adhesions near the leading edge but was recruited into other adhesions coincident in time and space with incorporation of tensin. Endogenous tensin and PP1alpha co-precipitated from cell lysates with isoform-specific PP1 antibodies. Chemical cross-linking of focal adhesion preparations with Lomant's reagent demonstrated molecular proximity of endogenous PP1alpha and tensin, whereas neither focal adhesion kinase nor vinculin …

Department of Occupational Therapy Faculty Papers

OBJECTIVE: We sought to assess validity of sensory integration outcomes research in relation to fidelity (faithfulness of intervention to underlying therapeutic principles).

METHOD: We identified core sensory integration intervention elements through expert review and nominal group process. Elements were classified into structural (e.g., equipment used, therapist training) and therapeutic process categories. We analyzed 34 sensory integration intervention studies for consistency of intervention descriptions with these elements.

RESULTS: Most studies described structural elements related to therapeutic equipment and interveners' profession. Of the 10 process elements, only 1 (presentation of sensory opportunities) was addressed in all studies. Most studies described fewer than …
