Regulation Of Human Cystic Fibrosis Transmembrane Conductance Regulator (Cftr) By Serum- And Glucocorticoid-Inducible Kinase (Sgk1), J. Denry Sato, M. Christine Chapline, Renee Thibodeau, Raymond A. Frizzell, Bruce A. Stanton Feb 2007

Regulation Of Human Cystic Fibrosis Transmembrane Conductance Regulator (Cftr) By Serum- And Glucocorticoid-Inducible Kinase (Sgk1), J. Denry Sato, M. Christine Chapline, Renee Thibodeau, Raymond A. Frizzell, Bruce A. Stanton

Dartmouth Scholarship

Background: Serum- and glucocorticoid-inducible kinase-1 (SGK1) increases CFTR Cl currents in Xenopus oocytes by an unknown mechanism. Because SGK increases the plasma membrane expression of other ion channels, the goal of this paper was to test the hypothesis that SGK1 stimulates CFTR Cl currents by increasing the number of CFTR Cl channels in the plasma membrane. Methods: CFTR Cl currents were measured in Xenopus oocytes by the two-electrode voltage clamp technique, and CFTR in the plasma membrane was determined by laser scanning confocal microscopy. Results: wt-SGK1 stimulated CFTR Cl currents by 42% and increased the amount of CFTR in the …

Cardeza Foundation for Hematologic Research

BACKGROUND: Neuroblastomas are characterized by chromosomal alterations with biological and clinical significance. We analyzed paired blood and primary tumor samples from 22 children with high-risk neuroblastoma for loss of heterozygosity (LOH) and DNA copy number change using the Affymetrix 10K single nucleotide polymorphism (SNP) array.

FINDINGS: Multiple areas of LOH and copy number gain were seen. The most commonly observed area of LOH was on chromosome arm 11q (15/22 samples; 68%). Chromosome 11q LOH was highly associated with occurrence of chromosome 3p LOH: 9 of the 15 samples with 11q LOH had concomitant 3p LOH (P = 0.016). Chromosome 1p …

Cephalalgiaphobia: A Possible Specific Phobia Of Illness., Mario F P Peres, Juliane P P Mercante, Vera Z Guendler, Felipe Corchs, Marcio A Bernik, Eliova Zukerman, Stephen Silberstein

Department of Jefferson Headache Center Papers and Presentations

Psychiatric comorbidity, mainly anxiety and depression, are common in chronic migraine (CM). Phobias are reported by half of CM patients. Phobic avoidance associated with fear of headache or migraine attack has never been adequately described. We describe 12 migraine patients with particular phobic-avoidant behaviours related to their headache attacks, which we classified as a specific illness phobia, coined as cephalalgiaphobia. All patients were women, mean age 42, and all had a migraine diagnosis (11 CM, all overused acute medications). Patients had either a phobia of a headache attack during a pain-free state or a phobia of pain worsening during mild …

The Enigma Of Struma Ovarii, Lawrence M. Roth, Aleksander Talerman Feb 2007

The Enigma Of Struma Ovarii, Lawrence M. Roth, Aleksander Talerman

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Since its first description in the early part of the twentieth century, struma ovarii has elicited considerable interest because of its many unique features; however, at present a number of aspects remain enigmatic. Although the typical presentation is that of a pelvic mass, unusual clinical manifestations such as hyperthyroidism, ascites, and Meigs' syndrome have been recognised. Uncommon macroscopic and especially histological patterns in struma can cause difficulties in diagnosis. Cystic strumas are challenging to diagnose both macroscopically and histologically. Proliferative changes within struma can be misdiagnosed as cancer. In regard to the occurrence of thyroid-type carcinoma in struma ovarii, precise …


Mouse Preimplantation Embryo Responses To Culture Medium Osmolarity Include Increased Expression Of Ccm2 And P38 Mapk Activation., Barry Fong, Patricia H Watson, Andrew J Watson Jan 2007

Mouse Preimplantation Embryo Responses To Culture Medium Osmolarity Include Increased Expression Of Ccm2 And P38 Mapk Activation., Barry Fong, Patricia H Watson, Andrew J Watson

Obstetrics & Gynaecology Publications

BACKGROUND: Mechanisms that confer an ability to respond positively to environmental osmolarity are fundamental to ensuring embryo survival during the preimplantation period. Activation of p38 mitogen-activated protein kinase (MAPK) occurs following exposure to hyperosmotic treatment. Recently, a novel scaffolding protein called Osmosensing Scaffold for MEKK3 (OSM) was linked to p38 MAPK activation in response to sorbitol-induced hypertonicity. The human ortholog of OSM is cerebral cavernous malformation 2 (CCM2). The present study was conducted to investigate whether CCM2 is expressed during mouse preimplantation development and to determine whether this scaffolding protein is associated with p38 MAPK activation following exposure of preimplantation …


A New Approach To Classify Risk In Dengue Infection Using Bioelectrical Impedance Analysis, F. Ibrahim, W.A.B. Wan Abas, M.N. Taib, C.C. Guan, S. Sulaiman Jan 2007

A New Approach To Classify Risk In Dengue Infection Using Bioelectrical Impedance Analysis, F. Ibrahim, W.A.B. Wan Abas, M.N. Taib, C.C. Guan, S. Sulaiman

Research Publications (2006 to 2010)

The study on risk classification was conducted on 183 hospitalized dengue patients (4 DF, 179 DHF). The severity of the risk criteria was determined based on three blood investigations, namely, platelet (PLT) count (less than or equal to 30 000 cells per mm 3), haematocrit (HCT) (increase by more than or equal to 20), and either aspartate aminotransferase (AST) level (raised by 5-fold the normal upper limit) or alanine aminotransferase (ALT) level (raised by 5-fold the normal upper limit). The patients were divided into three groups based on their risk factors and the corresponding bioelectrical impedance analysis (BIA) (i.e. bioelectrical …


Psychological Effects Of Not Having Equal Rights And Privileges In The Lesbian, Gay, Bisexual, Transgender Community: Activism As An Antidote?, David E. Baker Jan 2007

Psychological Effects Of Not Having Equal Rights And Privileges In The Lesbian, Gay, Bisexual, Transgender Community: Activism As An Antidote?, David E. Baker

PCOM Psychology Dissertations

Despite the prevalence of discrimination in American society, little is known about the effects of equal rights activism on mental health. Within the lesbian, gay, bisexual, transgender community, discrimination against marriage, adoption, employment, and other rights and privileges given to heterosexual individuals is still legal and socially accepted in most American communities. Previous research has suggested that these individuals have higher incidences of depression, anxiety, and substance use than the general population. The experience of discrimination and punishment responses learned from societal messages is believed to contribute to these clinical issues within this community. This qualitative study found that equal …

Idiopathic Granulomatous Mastitis Masquerading As Carcinoma Of The Breast: A Case Report And Review Of The Literature., Richard Tuli, Brian J O'Hara, Janet Hines, Anne L Rosenberg Jan 2007

Idiopathic Granulomatous Mastitis Masquerading As Carcinoma Of The Breast: A Case Report And Review Of The Literature., Richard Tuli, Brian J O'Hara, Janet Hines, Anne L Rosenberg

Department of Surgery Faculty Papers

BACKGROUND: Idiopathic granulomatous mastitis is an uncommon, benign entity with a diagnosis of exclusion. The typical clinical presentation of idiopathic granulomatous mastitis often mimics infection or malignancy. As a result, histopathological confirmation of idiopathic granulomatous mastitis combined with exclusion of infection, malignancy and other causes of granulomatous disease is absolutely necessary. CASE PRESENTATION: We present a case of a young woman with idiopathic granulomatous mastitis, initially mistaken for mastitis as well as breast carcinoma, and successfully treated with a course of corticosteroids. CONCLUSION: There is no clear clinical consensus regarding the ideal therapeutic management of idiopathic granulomatous mastitis. Treatment options …


A Turner Syndrome Neurocognitive Phenotype Maps To Xp22.3., Andrew R Zinn, David Roeltgen, Gerry Stefanatos, Purita Ramos, Frederick F Elder, Harvey Kushner, Karen Kowal, Judith L Ross Jan 2007

A Turner Syndrome Neurocognitive Phenotype Maps To Xp22.3., Andrew R Zinn, David Roeltgen, Gerry Stefanatos, Purita Ramos, Frederick F Elder, Harvey Kushner, Karen Kowal, Judith L Ross

Department of Pediatrics Faculty Papers

BACKGROUND: Turner syndrome (TS) is associated with a neurocognitive phenotype that includes selective nonverbal deficits, e.g., impaired visual-spatial abilities. We previously reported evidence that this phenotype results from haploinsufficiency of one or more genes on distal Xp. This inference was based on genotype/phenotype comparisons of individual girls and women with partial Xp deletions, with the neurocognitive phenotype considered a dichotomous trait. We sought to confirm our findings in a large cohort (n = 47) of adult women with partial deletions of Xp or Xq, enriched for subjects with distal Xp deletions. METHODS: Subjects were recruited from North American genetics and …

A Group Motivational Interviewing Intervention Reduces Drinking And Alcohol-Related Negative Consequences In Adjudicated College Women, Joseph W. Labrie, Alysha D. Thompson, Karen Huchting, Andrew Lac, Kevin Buckley

Heads Up!

College students who violate campus alcohol policies (adjudicated students) are at high risk for experiencing negative alcohol-related consequences and for undermining campus life. Further, college women may be especially at risk due to differential intoxication effects and sexual consequences experienced mainly by female students. Research on interventions for adjudicated students, especially adjudicated females, has been limited. One hundred and fifteen college women who received a sanction for violating campus alcohol policies participated in the study. The two hour group intervention focused on female-specific reasons for drinking and included decisional balance, goal setting and other exercises. Participants completed follow-up surveys for …


The Interplay Of Obesity And Asthma, James Plumb, Rickie Brawer, Nancy Brisbon Jan 2007

The Interplay Of Obesity And Asthma, James Plumb, Rickie Brawer, Nancy Brisbon

Department of Family & Community Medicine Faculty Papers

The relationships, interactions, and association between obesity and asthma are complex, and are active sources of hypotheses and research. An association between obesity and asthma has been reported in many studies, although considerable debate about the existence of the association and its meaning still exists. Potential associative relationships may result from genetics, immune system modifications, and mechanical mechanisms. The rising prevalence of asthma and obesity in children and adults, and the significant morbidity from both, makes it imperative that clinicians recognize the importance of weight management in patients with and without asthma.

Absence Of The Proapoptotic Bax Protein Extends Fertility And Alleviates Age-Related Health Complications In Female Mice, Gloria I. Perez, Andrea Jurisicova, Lisa Wise, Titiana Lipina, Marijana Kanisek, Allison Bechard, Yasushi Takai, Patricia Hunt, John Roder, Marc Grynpas, Jonathan L. Tilly

Psychology

The menopausal transition in human females, which is driven by a loss of cyclic ovarian function, occurs around age 50 and is thought to underlie the emergence of an array of health problems in aging women. Although mice do not undergo a true menopause, female mice exhibit ovarian failure long before death because of chronological age and subsequently develop many of the same age-associated health complications observed in postmenopausal women. Here we show in mice that inactivation of the proapoptotic Sax gene, which sustains ovarian lifespan into advanced age, extends fertile potential and minimizes many age-related health problems, including bone …

Repression Of Tumor Necrosis Factor-Related Apoptosis-Inducing Ligand (Trail) But Not Its Receptors During Oral Cancer Progression, Nadarajah Vigneswaran, Darryl C. Baucum, Jean Wu, Yahuan Lou, Jerry Bouquot, Susan Muller, Wolfgang Zacharias

Faculty, Staff and Student Publications

BACKGROUND: TRAIL plays an important role in host immunosurveillance against tumor progression, as it induces apoptosis of tumor cells but not normal cells, and thus has great therapeutic potential for cancer treatment. TRAIL binds to two cell-death-inducing (DR4 and DR5) and two decoy (DcR1, and DcR2) receptors. Here, we compare the expression levels of TRAIL and its receptors in normal oral mucosa (NOM), oral premalignancies (OPM), and primary and metastatic oral squamous cell carcinomas (OSCC) in order to characterize the changes in their expression patterns during OSCC initiation and progression. METHODS: DNA microarray, immunoblotting and immunohistochemical analyses were used to …

Homocysteine Levels In Preterm Infants: Is There An Association With Intraventricular Hemorrhage? A Prospective Cohort Study., Wendy J Sturtz, Kathleen H Leef, Amy B Mackley, Shailja Sharma, Teodoro Bottiglieri, David A Paul

Department of Pediatrics Faculty Papers

BACKGROUND: The purpose of this study was to characterize total homocysteine (tHcy) levels at birth in preterm and term infants and identify associations with intraventricular hemorrhage (IVH) and other neonatal outcomes such as mortality, sepsis, necrotizing enterocolitis, bronchopulmonary dysplasia, and thrombocytopenia. METHODS: 123 infants < 32 weeks gestation admitted to our Level III nursery were enrolled. A group of 25 term infants were enrolled for comparison. Two blood spots collected on filter paper with admission blood drawing were analyzed by a high performance liquid chromatography (HPLC) method. Statistical analysis included ANOVA, Spearman's Rank Order Correlation and Mann-Whitney U test. RESULTS: The median tHcy was 2.75 micromol/L with an interquartile range of 1.34 - 4.96 micromol/L. There was no difference between preterm and term tHcy (median 2.76, IQR 1.25 - 4.8 micromol/L vs median 2.54, IQR 1.55 - 7.85 micromol/L, p = 0.07). There was no statistically significant difference in tHcy in 31 preterm infants with IVH compared to infants without IVH (median 1.96, IQR 1.09 - 4.35 micromol/L vs median 2.96, IQR 1.51 - 4.84 micromol/L, p = 0.43). There was also no statistically significant difference in tHcy in 7 infants with periventricular leukomalacia (PVL) compared to infants without PVL (median 1.55, IQR 0.25 - 3.45 micromol/L vs median 2.85, IQR 1.34 - 4.82 micromol/L, p = 0.07). Male infants had lower tHcy compared to female; prenatal steroids were associated with a higher tHcy. CONCLUSION: In our population of preterm infants, there is no association between IVH and tHcy. Male gender, prenatal steroids and preeclampsia were associated with differences in tHcy levels.

Reproduction, Embryonic Development, And Maternal Transfer Of Contaminants In The Amphibian Gastrophryne Carolinensis, William Alexander Hopkins, Sarah Elizabeth Durant, Brandon Patrick Staub, Christopher Lee Rowe, Brian Phillip Jackson

Dartmouth Scholarship

Although many amphibian populations around the world are declining at alarming rates, the cause of most declines remains unknown. Environmental contamination is one of several factors implicated in declines and may have particularly important effects on sensitive developmental stages. Despite the severe effects of maternal transfer of contaminants on early development in other vertebrate lineages, no studies have examined the effects of maternal transfer of contaminants on reproduction or development in amphibians. We examined maternal transfer of contaminants in eastern narrow-mouth toads (Gastrophryne carolinensis) collected from a reference site and near a coal-burning power plant. Adult toads inhabiting …
