Solar Radiation Damage To Human Skin Mitochondria, Luciene Zanchetta

Doctoral

The central objective of this study was to assess solar radiation-induced changes in cellular function, mitochondrial function and mitochondrial DNA to further investigate the role of these energy-dedicated and metabolically essential organelles in the response to the main environmental stressor associated with skin cancer initiation. An in vitro approach was chosen employing the human malignant melanoma (A375) and human amelanotic melanoma (C32) cells and the human spontaneously immortalized keratinocytes (HaCaT). A Q-Sun Solar Simulator was used to expose cells to low-level simulated solar radiation (SSR) as it provides a mimic of solar radiation that is environmentally relevant in the UV …

Preliminary Studies Into Dna Binding Capabilities Of Ruthenium Nitro Nitrosyl As Anti-Tumor Pro-Drugs, Natasha Hansson

Seton Hall University Dissertations and Theses (ETDs)

The complex [Ru(bpy)z(NO)(N02)](PF6)2 was investigated as a potential anti­ tumor drug option. The nitrosyl group was displaced by reaction with azide ion in acetone to yield the solvento complex in situ. The products isolated from addition of a solution or slurry of guanine, adenine, cytosine or thiamine to the resulting [Ru(bpy)(N02)(acetone)t were investigated by electronic absorption spectroscopy, infra­ 1 red spectroscopy, H NMR spectroscopy and cyclic voltammetry. The results of the studies showed that guanine, adenine and thiamine form adducts with Ru(bpy)z(N02)(acetone)t. However, each base forms a unique complex as shown by electronic spectroscopy. Guanine is the strongest field ligand, …

Should We Be Concerned About Jejunoileal Atresia During Repair Of Duodenal Atresia?, Shawn D. St Peter, Danny C. Little, Katherine A. Barsness, Daniel R. Copeland, Casey M. Calkins, Suzanne Yoder, Steve S. Rothenberg, Saleem Islam, Kuojen Tsao, Daniel J. Ostlie

Manuscripts, Articles, Book Chapters and Other Papers

INTRODUCTION: During repair for duodenal atresia, it has been emphasized that inspection of the small bowel to identify a second atresia is required. The laparoscopic approach for repair of duodenal atresia has been criticized for its limitation to perform this step. Given that duodenal atresia and jejunoileal atresias do not share common embryologic origins, we question the validity of this concern. Therefore, we conducted a multicenter retrospective review of duodenal atresia patients to quantify the incidence of jejunoileal atresia in this population.

METHODS: After institutional review board approval (IRB #07-12-187X), a retrospective review was conducted on all patients who have …

Measurement Invariance Of The Kidney Disease And Quality Of Life Instrument (Kdqol-Sf) Across Veterans And Non-Veterans, Karen L. Saban, Fred B. Bryant, Dominic J. Reda, Kevin T. Stroupe, Denise M. Hynes

Psychology: Faculty Publications and Other Works

Background

Studies have demonstrated that perceived health-related quality of life (HRQOL) of patients receiving hemodialysis is significantly impaired. Since HRQOL outcome data are often used to compare groups to determine health care effectiveness it is imperative that measures of HRQOL are valid. However, valid HRQOL comparisons between groups can only be made if instrument invariance is demonstrated. The Kidney Disease Quality of Life-Short Form (KDQOL-SF) is a widely used HRQOL measure for patients with chronic kidney disease (CKD) however, it has not been validated in the Veteran population. Therefore, the purpose of this study was to examine the measurement invariance …

A Review Of Psychosocial Support And The Challenges Faced In Disclosing Hiv Positive Status To Children In Kibera, Katherine Lesyna

Independent Study Project (ISP) Collection

The AIDS pandemic has become an increasingly global problem as well as an everyday reality for most people living in sub-Saharan Africa. In 2009, an estimation of the number of adults and children living with HIV/AIDS in sub-Saharan Africa totaled around 22.4 million.1 The people that have been affected most by the pandemic are women and children.
In Kenya, about 1.5 million people are infected with HIV, about 180,000 of them being children.2 While a lot has been done to reduce HIV infections and treat those who are infected, children have been left behind until recently. There is still much …

Antibiotic Susceptibility Patterns Of Helicobacter Pylori And Triple Therapy In A High-Prevalence Area, Javed Yakoob, Shahab Abid, Z. Abbas, S. N. W. Jafri

Department of Medicine

This study aims to determine primary Helicobacter pylori resistance and its effect on eradication of the organism. Ninety-two Patients with dyspeptic symptoms were enrolled. H. pylori was cultured and antibiotic sensitivity was determined by the Epsilometer test (Etest) for clarithromycin (CLR), amoxicillin (AMX) and metronidazole (MTR). 23S ribosomal RNA (rRNA) point mutations associated with clarithromycin resistance were also detected. Patients were treated with omeprazole (40 mg daily), CLR (500 mg) and AMX (1g twice a day) for 14 days. A (14)C-urea breath test ((14)C-UBT) was repeated four weeks after completion of treatment to confirm eradication. Triple therapy failure was seen …

Morphological Study Of Emulsion-Assisted Cholesterol Precipitation Processes, Vuk Uskoković

Pharmacy Faculty Articles and Research

Crystallization of cholesterol in chemical conditions that involve the presence of emulsions of three different types of surface active agents—cationic, anionic, and nonionic—was investigated by means of scanning and transmission electron microscopic analyses. In contrast with the previous attempts to modify the typical plate- and needle-shaped character of biaxially grown cholesterol crystals, the present study indicates that spherical templates of fine emulsion droplets may impose spherical morphologies to cholesterol particles nucleated within.

Cardiovascular Risk Associated With Interactions Among Polymorphisms In Genes From The Renin-Angiotensin, Bradykinin, And Fibrinolytic Systems, John P. Bentley, Folkert W. Asselbergs, Christopher S. Coffey, Patricia R. Hebert, Jason H. Moore, Hans L. Hillege, Wiek H. Van Gilst

Dartmouth Scholarship

Background: Vascular fibrinolytic balance is maintained primarily by interplay of tissue plasminogen activator (t-PA) and plasminogen activator inhibitor type 1 (PAI-1). Previous research has shown that polymorphisms in genes from the renin- angiotensin (RA), bradykinin, and fibrinolytic systems affect plasma concentrations of both t-PA and PAI-1 through a set of gene-gene interactions. In the present study, we extend this finding by exploring the effects of polymorphisms in genes from these systems on incident cardiovascular disease, explicitly examining two-way interactions in a large population- based study.

Section of Pulmonary & Critical Care

Background/Objectives: In developing countries, spirometry has not been considered a part of routine medical check-up. The purpose of the study was to establish the usefulness of spirometry as a primary screening tool in detecting air flow obstruction (AFO) during routine medical check-up (RMC). Methods: This was a hospital based, retrospective, non-randomized case series study of 3696 participants, who presented to hospital for routine medical check-up. All subjects were assisted at the Pulmonary Medicine Department, from January 2003 till December 2008 who, having met other inclusion criteria, underwent spirometry. Data were analyzed using proportion, group means, standard deviations and …

Residence In A Distressed County In Appalachia As A Risk Factor For Diabetes, Behavioral Risk Factor Surveillance System, 2006-2007, Lawrence Barker, Richard Crespo, Robert B. Gerzoff, Sharon Denham, Molly Shrewsberry, Darrlyn Cornelius-Averhart

Family and Community Health

Introduction

We compared the risk of diabetes for residents of Appalachian counties to that of residents of non-Appalachian counties after controlling for selected risk factors in states containing at least 1 Appalachian county.

Methods

We combined Behavioral Risk Factor Surveillance System data from 2006 and 2007 and conducted a logistic regression analysis, with self-reported diabetes as the dependent variable. We considered county of residence (5 classifications for Appalachian counties, based on economic development, and 1 for non-Appalachian counties), age, sex, race/ethnicity, education, household income, smoking status, physical activity level, and obesity to be independent variables. The classification “distressed” refers to …

Prevalences Of Giardia Lamblia And Cryptosporidium Parvum Infection In Adults Presenting With Chronic Diarrhoea, Javed Yakoob, Zaigham Abbas, M. Asim Beg, Shagufta Naz, Rustam Khan, Muhammad Islam, Wasim Jafri

Section of Gastroenterology

iardia lamblia and Cryptosporidium parvum are both waterborne pathogens associated with diarrhoea in developing countries. In a recent study based at the Aga Khan University in Karachi, 334 adults aged 16–83 years (178 patients with chronic diarrhoea and 156 diarrhoea-free volunteers who acted as controls) were checked for infection with these parasites, using stool microscopy and/or PCR. Overall, 21 (6.3%) and 29 (8.7%) of the subjects were found positive for G. lamblia by microscopy and PCR, respectively, while the corresponding values for C. parvum were 13 (3.9%) and 14 (4.2%). Although, compared with the diarrhoea-free controls, the patients with diarrhoea …

Development Of A Lung Cancer-Specific Model For Support Group Interest, Laura Testerman

Loma Linda University Electronic Theses, Dissertations & Projects

Despite high levels of both emotional and physical distress and desire for utilization of support group services, lung cancer patients rarely participate in these supportive services. Lung cancer survivors’ interest in and use of supportive psychosocial services remains poorly understood, and Internet-based services may be of particular benefit to this population. The Behavioral Model for Vulnerable Populations, which emphasizes Predisposing (i.e., demographic as well as attitudes about support services), Enabling (i.e., accessibility of services), and Illness (i.e., need for services based on health) factors, was applied to the prediction of survivors’ behavioral intention to participate in face-to-face support groups (F2F) …

Harnessing The Effect Of Adoptively Transferred Tumor-Reactive T Cells On Endogenous (Host-Derived) Antitumor Immunity, Yolanda Nesbeth, Jose R. Conejo-Garcia

Dartmouth Scholarship

Adoptive T cell transfer therapy, the ex vivo activation, expansion, and subsequent administration of tumor-reactive T cells, is already the most effective therapy against certain types of cancer. However, recent evidence in animal models and clinical trials suggests that host conditioning interventions tailored for some of the most aggressive and frequent epithelial cancers will be needed to maximize the benefit of this approach. Similarly, the subsets, stage of differentiation, and ex vivo expansion procedure of tumor-reactive T cells to be adoptively transferred influence their in vivo effectiveness and may need to be adapted for different types of cancer and host …

Childhood Injuries In Pakistan: Results From Two Communities, Seema Zainulabdin Lasi, Ghazala Rafique, Habib Peermohammad

Human Development Programme

The study aimed at determining the incidence, nature, and extent of childhood injuries in two suburban and rural communities of Pakistan. The findings of the study are based on a cross-sectional survey of 2,292 children aged 1-8 years. Information was sought retrospectively from the primary caregiver on the occurrence of injury that required formal or informal medical consultation during the past three months. The incidence rate of non-fatal injuries that required care outside home for children aged 1-8 years was 19.7 injuries per 100 person (child)-years of exposure [95% confidence interval (CI) 16.41-23.51]: 26.5 injuries per 100 person (child)-years of …

Localization And Binding Characteristics Of Kaposi's Sarcoma-Associated Herpesvirus Bcl-2 Protein In The Prevention Of Apoptosis, Erin T. St.Angelo

Seton Hall University Dissertations and Theses (ETDs)

Kaposi's sarcoma-associated herpesvirus (KSHV) is the causative agent of various diseases, and it encodes a Bcl-2 homolog, KS-Bcl-2. The Bcl-2 family is important in regulating cellular apoptosis. Pro-apoptotic Bcl-2 family members promote apoptosis through mitochondrial pore formation by Bak and Bax, or through BH3 only domain activators and sensitizers. Anti-apoptotic members, such as cellular Bcl-2 prevent apoptosis through interactions with pro-apoptotic proteins, for instance inhibiting pore formation by binding to Bak and/or Bax. Even though, KS-Bcl-2 has been shown to have an anti-apoptotic function like its homolog, it does not bind to either Bak or Bax, and little is known …

Precipitating Factors And The Outcome Of Hepatic Encephalopathy In Liver Cirrhosis, Khalid Mumtaz, Umair Syed Ahmed, Shahab Abid, Noshaba Baig, Saeed Hamid, Wasim Jafri

Section of Gastroenterology

Objective: To determine precipitants of hepatic encephalopathy (HE) and their impact on hospital stay and mortality.

Study Design: Cross-sectional, analytical study. Place and Duration of Study: The Aga Khan University Hospital, from January 2005 to December 2007.

Methodology: Consecutive patients admitted with different grades of HE were evaluated between January 2005 and December 2007.

Chi-square test was used to compare the proportion of precipitating factors versus hospital stay and grade with significance at p < 0.05.

Results: Of the 404 patients 252 (62%) …

The Role Of Unrealistic Optimism In Explaining Preventive Behaviors In High Versus Low Endemic Malaria Settings In Belize, Daniel G. Handysides

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Of all the diseases an individual can encounter in the world, malaria is one of the most destructive. Simple measures like sleeping under a bednet would greatly reduce the burden (Abeku, 2007). When people estimate their risk relative to others, they are most often unrealistically optimistic, which may explain why those at risk often fail to perform behaviors, such as using a bednet that will reduce their risk. However, one study showed that people at high risk for malaria held pessimistic perceptions of their risk for the disease, but the reasons for this finding are unclear (Morrison, Ager, & …

The Relationship Between The Level Of Support Group Participation And Psychosocial Factors In Prostate Cancer Patients Treated With Proton Therapy, Carol A. L. Davis

Loma Linda University Electronic Theses, Dissertations & Projects

Background. The role of support groups for cancer patients is known to be beneficial in helping people adjust to the disease, and cope with the myriad of effects that cancer has on quality of life. Although many people express interest in attending such support groups, few attend regularly. It is unclear what characteristics distinguish those who use such services from those who do not, especially among proton therapy patients.

Objective. To examine demographic and psychosocial characteristics associated with the Brotherhood of the Balloon (BOB) prostate cancer support group membership, a unique treatment-focused group originating at Loma Linda University Medical Center …

Improving Quantitative Treatment Response Monitoring With Deformable Image Registration, Blake A. Cannon

Dissertations and Theses (Open Access)

Quantitative imaging with 18F-FDG PET/CT has the potential to provide an in vivo assessment of response to radiotherapy (RT). However, comparing tissue tracer uptake in longitudinal studies is often confounded by variations in patient setup and potential treatment induced gross anatomic changes. These variations make true response monitoring for the same anatomic volume a challenge, not only for tumors, but also for normal organs-at-risk (OAR). The central hypothesis of this study is that more accurate image registration will lead to improved quantitation of tissue response to RT with 18F-FDG PET/CT. Employing an in-house developed “demons” based deformable image registration algorithm, …
