Disclosure Of Apoe Genotype For Risk Of Alzheimer's Disease, Peter J. Whitehouse, Melissa Barber Butson

Faculty Scholarship

BACKGROUND: The apolipoprotein E (APOE) genotype provides information on the risk of Alzheimer's disease, but the genotyping of patients and their family members has been discouraged. We examined the effect of genotype disclosure in a prospective, randomized, controlled trial. METHODS: We randomly assigned 162 asymptomatic adults who had a parent with Alzheimer's disease to receive the results of their own APOE genotyping (disclosure group) or not to receive such results (nondisclosure group). We measured symptoms of anxiety, depression, and test-related distress 6 weeks, 6 months, and 1 year after disclosure or nondisclosure. RESULTS: There were no significant differences between the …

Complexity, Cofactors, And The Failure Of Aids Policy In Africa, Eileen Stillwaggon

Economics Faculty Publications

Global AIDS policy still treats HIV as an exceptional case, abstracting from the context in which infection occurs. Policy is based on a simplistic theory of HIV causation, and evaluated using outdated tools of health economics. Recent calls for a health systems strategy – preventing and treating HIV within a programme of comprehensive health care – have not yet influenced the silo approach of AIDS policy.

Evidence continues to accumulate, showing that multiple factors, such as malnutrition, malaria and helminthes, increase the risk of sexual and vertical transmission of HIV. Moreover, complementary interventions that reduce viral load, improve immune response, …

Pediatrics Faculty Publications

The gynecologist may be the only physician that an adolescent depends on for primary and reproductive healthcare services. Because adolescent females often make personal healthcare decisions without the benefit of supportive parents/caregivers, it is imperative that the gynecologist understands the developmental issues encountered during this phase of life. The objective of this study is to identify cited complaints of adolescent females seeking reproductive care and, thus, provide gynecologists with needed information about the medical/mental health issues that may be encountered during routine reproductive care exams. The study group was adolescent females between the ages of 12 and 20 years old. …

Quality Of Life And Depression: Outcome Markers For A Weight Management Program, Cecilia Dueñas

Loma Linda University Electronic Theses, Dissertations & Projects

Pediatric obesity has become a national epidemic and current trends suggest a continued increase. Obese children have been found to have higher incidences of depression and a lower quality of life (QOL) than children from other often more severe medical populations. As a result, weight management programs are on the increase with the majority measuring outcome success through weight loss and decreased body mass index (BMI). It is evident however, that health factors are not the only factors associated with obesity, and that psychosocial components are important as well. The Loma Linda University Growing Fit Program is unique in that …

Mnte-2-Pyp And Radiation In A Prostate Cancer Model: Implications For Radiotherapy, Adeola Y. Makinde

Loma Linda University Electronic Theses, Dissertations & Projects

A major limitation of successful radiation therapy in cancer treatment is the increase in normal tissue damage as higher doses are used to achieve greater tumor destruction. Radiation dose optimization in cancer therapy requires achieving maximum tumor destruction with minimal damage to normal tissue Antioxidants have been shown to protect normal tissues against radiation damage, as radiation-induced tissue damage results predominantly from reactive oxygen species that directly damage cellular components. However, for effective use as normal tissue radioprotectants in radiotherapy, these antioxidants must not protect the tumors. Mn (III) tetrakis (N-ethylpyridinium-2-yl) porphyrin (MnTE-2-PyP) is a metalloporphyrin antioxidant that has been …

Photochemical Delivery Of Bleomycin In Malignant Glioma Cells, Joseph William Blickenstaff Iii

UNLV Theses, Dissertations, Professional Papers, and Capstones

Despite continued efforts, glioblastoma multiforme (GBM) remains an incurable form of primary brain cancer. Surgical resection followed by radiation treatment and chemotherapy have been the most effective modalities in prolonging median survival time to 14 months. This research aims to study the response of two different cell culture models to a novel drug delivery method termed photochemical internalization (PCI). PCI is a technique to improve the utilization of macromolecules (e.g. the chemotherapeutic drug bleomycin) in site-specific cancer therapy. This concept is based on the use of specially designed photosensitizers (e.g. aluminum phthalocyanine disulfonate; AlPcS _2a ) which preferentially localize in …

Correlates Of Soy Food Consumption In Adventist Health Study-2, Yen Ang

Loma Linda University Electronic Theses, Dissertations & Projects

Much has been discussed about the health benefits and risks of soy consumption but very little is known about who the consumers are. Most of what is known has been observed mainly in Asian populations who consume high levels of soy. Very little is known about soy food intake in the western population who typically has low consumption level. The Seventh-Day Adventist cohort in North America is the only population known in the West with soy food intake that is comparable to the Asian population living in the East.

Soy consumers in a population known for its healthier lifestyle and …

Uptake through the dopamine transporter (DAT) represents the primary mechanism used to terminate dopaminergic transmission in brain. Although it is well known that dopamine (DA) taken up by the transporter is used to replenish synaptic vesicle stores for subsequent release, the molecular details of this mechanism are not completely understood. Here, we identified the synaptic vesicle protein synaptogyrin-3 as a DAT interacting protein using the split ubiquitin system. This interaction was confirmed through coimmunoprecipitation experiments using heterologous cell lines and mouse brain. DAT and synaptogyrin-3 colocalized at presynaptic terminals from mouse striatum. Using fluorescence resonance energy transfer microscopy, we show …

Department of Radiation Oncology

Hypertrophic osteoarthropathy is characterized by clubbing of the digital tips and periosteal reaction of long bones. Most of the cases are associated with malignancy or other conditions such as congenital heart disease, liver cirrhosis, pulmonary fibrosis, biliary atresia and gastrointestinal polyps. Hypertrophic osteoarthropathy associated with malignancy is rare in children. A few cases of hypertrophic osteoarthropathy in children with nasopharyngeal carcinoma have been reported. This is a case of hypertrophic osteoarthropathy associated with nasopharyngeal carcinoma with lung and bone metastasis in a 16 year old girl. In this case, lung metastases progressed after intensive chemotherapy and hypertrophic osteoarthropathy (Clubbing) persisted.

Social Cognitive Predictors Of Diabetes Outcomes In Latinos And Whites, Diana Brown

Loma Linda University Electronic Theses, Dissertations & Projects

Investigating health care disparities in ethnic minority populations is an increasingly urgent issue as these disparities lead to higher morbidity and mortality in minorities (National Center of Health Statistics, 2000). There is clear evidence that Latino Americans, the fastest growing minority group in the United States, are more likely to be diagnosed with and experience more severe complications from type 2 diabetes than Anglo Americans. This study surveyed 38 White and 33 Latino diabetes patients from outpatient clinics in an academic medical center. Cultural values (individualism and collectivism), mental health (social support, mental health), and self-efficacy (diabetes and exercise) were …
