BACKGROUND: Pregnancy is a time of significant physiological and physical change for women. In particular, it is a time at which many women are at risk of gaining excessive weight. We describe the rationale and methods of the Health in Pregnancy and Post-birth (HIPP) Study, a study which aims primarily to determine the effectiveness of a specialized health coaching (HC) intervention during pregnancy, compared to education alone, in preventing excessive gestational weight gain and postpartum weight retention 12 months post birth. A secondary aim of this study is to evaluate the mechanisms by which our HC intervention impacts on weight …

Electrophysiological Examination Of Embodiment In Vision And Action., Jeremy Goslin, Thomas Dixon, Martin H. Fischer, Angelo Cangelosi, Rob Ellis

School of Psychology

A wealth of behavioral data has shown that the visual properties of objects automatically potentiate motor actions linked with them, but how deeply are these affordances embedded in visual processing? In the study reported here, we used electrophysiological measures to examine the time course of affordance resulting from the leftward or rightward orientation of the handles of common objects. Participants were asked to categorize those objects using a left- or right-handed motor response. Lateralized readiness potentials showed rapid motor preparation in the hand congruent with the affordance provided by the object only 100 to 200 ms after stimulus presentation and …

Journal Articles: Pulmonary & Critical Care Med

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is characterized by chronic inflammation in the small airways. The effect of inhaled corticosteroids (ICS) on lung inflammation in COPD remains uncertain. We sought to determine the effects of ICS on inflammatory indices in bronchial biopsies and bronchoalveolar lavage fluid of patients with COPD.

METHODS: We searched Medline, Embase, Cinahl, and the Cochrane database for randomized, controlled clinical trials that used bronchial biopsies and bronchoalveolar lavage to evaluate the effects of ICS in stable COPD. For each chosen study, we calculated the mean differences in the concentrations of inflammatory cells before and after treatment …

The Long And Short Of It: The Role Of Telomeres In Fetal Origins Of Adult Disease., Stephanie E Hallows, Timothy Regnault, Dean H Betts

Paediatrics Publications

Placental insufficiency, maternal malnutrition, and other causes of intrauterine growth restriction (IUGR) can significantly affect short-term growth and long-term health. Following IUGR, there is an increased risk for cardiovascular disease and Type 2 Diabetes. The etiology of these diseases is beginning to be elucidated, and premature aging or cellular senescence through increased oxidative stress and DNA damage to telomeric ends may be initiators of these disease processes. This paper will explore the areas where telomere and telomerase biology can have significant effects on various tissues in the body in IUGR outcomes.

Neural Network Diagnostic System For Dengue Patients Risk Classification, T. Faisal, M.N. Taib, Fatimah Ibrahim

Research Publications (2011 to 2015)

With the dramatic increase of the worldwide threat of dengue disease, it has been very crucial to correctly diagnose the dengue patients in order to decrease the disease severity. However, it has been a great challenge for the physicians to identify the level of risk in dengue patients due to overlapping of the medical classification criteria. Therefore, this study aims to construct a noninvasive diagnostic system to assist the physicians for classifying the risk in dengue patients. Systematic producers have been followed to develop the system. Firstly, the assessment of the significant predictors associated with the level of risk in …

The Queen Of The Household: Mothers, Other Mothers, And Female Genealogy On The Plantation In Postslavery Women's Fiction, Correna Catlett Merricks

Electronic Theses and Dissertations

In many ways, the plantation defined the U.S. South because it was the primary site of production, and therefore income, for prominent southerners. In addition to being a site of production, the plantation created a complex series of connected relationships that was imagined by the plantocracy to be a large family unit. It functioned according to a specific hierarchical model that was primarily based on a patriarchal understanding of genealogy. Yet Kate Chopin's "Désirée's Baby" and "La Belle Zoraïde," Pauline Hopkins's Contending Forces, Zora Neale Hurston's Their Eyes Were Watching God, Julia Peterkin's Scarlet Sister Mary, Eudora Welty's Delta Wedding, …

The Impact Of Participation In A Secondary School-Based Mentoring Program On Urban Females After High School Graduation, Sandra Lee Wesolowski

As thoughts of the future weigh heavily on many adolescents' minds, the at-risk urban adolescent female are at an especially critical point; every decision she makes on a daily basis has the potential to affect the rest of her life (Way, 1995). However, secondary school-based mentoring programs can provide the modality to intervene with at-risk urban adolescent females to increase the likelihood of success both while in high school and after high school graduation.

This study is a phenomonologically-oriented qualitative study that asks the question: What is the impact of participation in a secondary school-based mentoring program on the lives …

Sexual Dimorphism In Periapical Inflammation And Bone Loss From Map Kinase Phosphatase-1 Deficient Mice, Justin Mcabee

MUSC Theses and Dissertations

Introduction: Mitogen Activating Protein (MAPK) kinase phosphatase-1 (MKP-1) has been shown to be a key negative regulator of the MAP kinase pathways of the innate immune system. The impact of MKP-1 in an endodontic model has yet to be studied. Thus, the purpose of this study was to determine the role of MKP-1 in a bacterial-driven model of pathological endodontic bone loss. Methods: Pulps were exposed in both lower 1st molars of 10-week old Dusp-1+1+IMKP-1 +1+ and Dusp-1-1-IMKP-1-1- mice and left open to the oral environment for either 3 or 8 weeks. At sacrifice, mandibles were harvested and scanned by …

The Role Of Cd147 In Breast Cancer Progression, George Daniel Grass

MUSC Theses and Dissertations

In the U.S., approximately 40,000 women will die from breast cancer this year, while an additional 230,500 women will be newly diagnosed with invasive breast disease. Despite tremendous advancement leading to earlier detection and novel therapeutic approaches, recurrent metastatic breast cancer remains a major cause of mortality. Invasive breast cancer cells employ specialized actin-rich protrusions called invadopodia, which are enriched in proteases, to degrade the extracellular matrix and these structures correlate with metastasis in vivo. The multifunctional immunoglobulin superfamily protein emmprin (CD147) is highly enriched on the surface of malignant breast cancer cells and is associated with matrix metalloproteinase (MMP) …

Characterization Of The Behavioral, Biochemical And Molecular Indices Of Stress Produced By Nicotine Exposure And Withdrawal In Male And Female Rats, Oscar Valentin Torres

Open Access Theses & Dissertations

Introduction: Tobacco use is a major economic and health problem. Particularly concerning is that women consume more tobacco products, have a more difficult time quitting, and are less likely to benefit from cessation therapies than men. As a result, women are at higher risk of developing tobacco-related diseases. Women are generally more susceptible to stress and are more likely to cope with stress by smoking as compared to men. During abstinence, women also experience intense anxiety as compared to men and report that the anxiety-reducing effects of smoking are the main reason for continued use and relapse. Thus, stress produced …

The Potential Of The Angle Of The First Rib, Head To Tubercle, In Sexing Adult Individuals In Forensic Contexts, Paige Whitney Elrod

LSU Master's Theses

Accurately assessing the sex of an adult human skeleton is fundamental in forming the biological profile used in forensic anthropology (Patil and Mody, 2005). The first rib was chosen due to its distinct shape, compact size and increased sustainability to the taphonomic processes encountered in forensic and bioarchaeological situations. The first rib has been examined in previous studies; however, these studies have focused mainly on the sternal end of the rib. This study looks at the angle created between the tubercle and head and its potential use as an indication of the sex of an individual. This angle, created by …

Minimum Cost Of Transport In Asian Elephants: Do We Really Need A Bigger Elephant?, V. A. Langman, M. F. Rowe, T. J. Roberts, N. V. Langman, C. R. Taylor

Dartmouth Scholarship

Body mass is the primary determinant of an animal’s energy requirements. At their optimum walking speed, large animals have lower mass-specific energy requirements for locomotion than small ones. In animals ranging in size from 0.8 g (roach) to 260 kg (zebu steer), the minimum cost of transport (COT_min) decreases with increasing body size roughly as COT_min∝body mass (M_b)^{–0.316±0.023} (95% CI). Typically, the variation of COT_min with body mass is weaker at the intraspecific level as a result of physiological and geometric similarity within closely related species. The interspecific relationship estimates that …

Kimmel Cancer Center Faculty Papers

INTRODUCTION:

The incidence of melanoma is dramatically increasing worldwide. We hypothesized that the ratio of metastatic to examined lymph node ratio (LNR) would be the most important prognostic factor for stage III patients.

METHODS:

We retrospectively reviewed our institutional database of melanoma patients and identified 168 patients who underwent lymph node dissection (LND) for stage III disease between 1993 and 2007. Patients were divided into three groups based on LNR (≤10%, n = 93; 10-≤25%, n = 45; and >25%, n = 30). Univariate and multivariate analysis was performed using Cox proportional hazards model.

RESULTS:

The median survival time of …

The Texas Heart Institute Journal

We investigated the prognostic importance of plasma myeloperoxidase levels in patients with ST-elevation myocardial infarction (STEMI) at long-term follow-up, and we analyzed the correlations between plasma myeloperoxidase levels and other biochemical values.

We evaluated 73 consecutive patients (56 men; mean age, 56 ±11 yr) diagnosed with acute STEMI and 46 age- and sex-matched healthy control participants. Patients were divided into 2 groups according to the median myeloperoxidase level (Group 1: plasma myeloperoxidase ≤68 ng/mL; and Group 2: plasma myeloperoxidase >68 ng/mL). Patients were monitored for the occurrence of major adverse cardiovascular events (MACE), which were defined as cardiac death; reinfarction; …

Blood-Brain Barrier Abnormalities Caused By Hiv-1 Gp120: Mechanistic And Therapeutic Implications., Jean-Pierre Louboutin, David S Strayer

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The blood-brain barrier (BBB) is compromised in many systemic and CNS diseases, including HIV-1 infection of the brain. We studied BBB disruption caused by HIV-1 envelope glycoprotein 120 (gp120) as a model. Exposure to gp120, whether acute [by direct intra-caudate-putamen (CP) injection] or chronic [using SV(gp120), an experimental model of ongoing production of gp120] disrupted the BBB, and led to leakage of vascular contents. Gp120 was directly toxic to brain endothelial cells. Abnormalities of the BBB reflect the activity of matrix metalloproteinases (MMPs). These target laminin and attack the tight junctions between endothelial cells and BBB basal laminae. MMP-2 and …

Decorin Protein Core Affects The Global Gene Expression Profile Of The Tumor Microenvironment In A Triple-Negative Orthotopic Breast Carcinoma Xenograft Model., Simone Buraschi, Thomas Neill, Rick T Owens, Leonardo A Iniguez, George Purkins, Rajanikanth Vadigepalli, Barry Evans, Liliana Schaefer, Stephen C Peiper, Zi-Xuan Wang, Renato V Iozzo

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Decorin, a member of the small leucine-rich proteoglycan gene family, exists and functions wholly within the tumor microenvironment to suppress tumorigenesis by directly targeting and antagonizing multiple receptor tyrosine kinases, such as the EGFR and Met. This leads to potent and sustained signal attenuation, growth arrest, and angiostasis. We thus sought to evaluate the tumoricidal benefits of systemic decorin on a triple-negative orthotopic breast carcinoma xenograft model. To this end, we employed a novel high-density mixed expression array capable of differentiating and simultaneously measuring gene signatures of both Mus musculus (stromal) and Homo sapiens (epithelial) tissue origins. We found that …

Kaempferol Nanoparticles Achieve Strong And Selective Inhibition Of Ovarian Cancer Cell Viability., Haitao Luo, Bingbing Jiang, Bingyun Li, Zhaoliang Li, Bing-Hua Jiang, Yi Charlie Chen

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Ovarian cancer is one of the leading causes of cancer death for women throughout the Western world. Kaempferol, a natural flavonoid, has shown promise in the chemoprevention of ovarian cancer. A common concern about using dietary supplements for chemoprevention is their bioavailability. Nanoparticles have shown promise in increasing the bioavailability of some chemicals. Here we developed five different types of nanoparticles incorporating kaempferol and tested their efficacy in the inhibition of viability of cancerous and normal ovarian cells. We found that positively charged nanoparticle formulations did not lead to a significant reduction in cancer cell viability, whereas nonionic polymeric nanoparticles …

Division of Pulmonary, Allergy, and Critical Care Medicine Faculty Papers

RATIONALE: Pulmonary Alveolar Proteinosis (PAP) patients exhibit an acquired deficiency of biologically active granulocyte-macrophage colony stimulating factor (GM-CSF) attributable to GM-CSF specific autoantibodies. PAP alveolar macrophages are foamy, lipid-filled cells with impaired surfactant clearance and markedly reduced expression of the transcription factor peroxisome proliferator-activated receptor gamma (PPARγ) and the PPARγ-regulated ATP binding cassette (ABC) lipid transporter, ABCG1. An open label proof of concept Phase II clinical trial was conducted in PAP patients using rituximab, a chimeric murine-human monoclonal antibody directed against B lymphocyte specific antigen CD20. Rituximab treatment decreased anti-GM-CSF antibody levels in bronchoalveolar lavage (BAL) fluid, and 7/9 patients …

Department of Medical Oncology Faculty Papers

BACKGROUND: RRM1 and ERCC1 overexpression has been extensively investigated as potential predictive markers of tumor sensitivity to conventional chemotherapy agents, most thoroughly in lung cancer. However, data in pancreatic cancer are scarce.

METHODS: We investigated the mRNA and protein expression of ERCC1 and RRM1 by RT-PCR and immunohistochemistry (IHC) in formalin-fixed, paraffin-embedded pancreatic ductal carcinoma (PDA) tissues. The primary outcome investigated was the association between RRM1 and ERCC1 expression and overall survival (OS) or disease-free survival (DFS).

RESULTS: A total of 94 patients with resected PDA were included in this study. Most of them (87%) received gemcitabine based chemotherapy. Data …

Hypoplastic Right-Heart Syndrome Presenting As Multiple Miscarriages, Chadi Dib, Philip A Araoz, Norman P Davies, Joseph A Dearani, Naser M Ammash

The Texas Heart Institute Journal

Reversible causes of miscarriage are many, but they affect only 1% of women who are trying to conceive. Herein, we describe the case of a 23-year-old woman who presented for evaluation of repeated miscarriages and was found to have hypoxemia and erythrocytosis. Further evaluation revealed hypoplastic right-heart syndrome with an intracardiac shunt. She underwent hybrid repair with pulmonary valve balloon valvuloplasty, followed by surgery to perform atrial septal defect closure and a Glenn anastomosis. The erythrocytosis and hypoxemia resolved, and she was able to conceive and deliver a healthy baby at term 2 years later.

This is a unique case …
