Using Photoactive Vitamin Nanoparticles As Photodynamic Antimicrobial Chemotherapeutic (Pact) Agents To Treat Chronic Wounds, Rahul A. Khanke
Using Photoactive Vitamin Nanoparticles As Photodynamic Antimicrobial Chemotherapeutic (Pact) Agents To Treat Chronic Wounds, Rahul A. Khanke
All Capstone Projects
The objective of the proposed study is to develop new materials and methods to manage microbial growth in chronic wounds using phototherapy. Chronic wounds are considered as a worldwide health problem. The most common chronic wounds can be classified into three categories: venous ulcers, diabetic ulcers, and pressure ulcers. Venous ulcers, which usually occur in the legs, account for about 70% to 90% of chronic wounds and can become infected easily. Venous ulcers are sores that develop after veins in the legs have been damaged. These ulcers can penetrate deeply into the skin. Occasionally, if a venous ulcer persists for …
Synthesis And Analytical Evaluation Of Folate Conjugates For Use In Cancer Cell Detection, Sneha Reddy Kuthuru
Synthesis And Analytical Evaluation Of Folate Conjugates For Use In Cancer Cell Detection, Sneha Reddy Kuthuru
All Capstone Projects
Recent clinical studies have shown the importance of folate receptor in drug delivery system as they increase the potency and reduce toxicity of many cancer therapies. The folate receptor alpha ( FR-a) binds with high affinity for folic acid and serves for receptor mediated transport of folate into cells. Folate is necessary for DNA metabolism and thus it is speculated that rapidly dividing cancer cells have an increased requirement for folic acid. It is known that FR-a levels are elevated in specific malignant diseases (solid tumors, leukemia) and thus the FR receptor serves as useful targeting moiety for the diagnosis …

All Capstone Projects
One of the largest challenges that food manufactures are facing today is the management of food allergens. Allergenic protein in trace amounts, part per million concentrations, will trigger a reaction in some individuals. Food manufacturers need to prevent allergen cross-contamination by performing adequate sanitation after production of an allergenic containing food. Allergen detection kits are used to determine if sufficient protein was removed from the equipment surfaces during sanitation. One kit on the market is the 3M™ Clean- Trace™ Surface Protein (Allergen) swab tests. The test qualitatively detects the presence of protein based on the biuret reaction and will yield …

The Pathways To Mental Health Care Of First-Episode Psychosis Patients: A Systematic Review., Kelly K. Anderson, Rebecca Fuhrer, Ashok K. Malla
Epidemiology and Biostatistics Publications
BACKGROUND: Although there is agreement on the association between delay in treatment of psychosis and outcome, less is known regarding the pathways to care of patients suffering from a first psychotic episode. Pathways are complex, involve a diverse range of contacts, and are likely to influence delay in treatment. We conducted a systematic review on the nature and determinants of the pathway to care of patients experiencing a first psychotic episode.
METHOD: We searched four databases (Medline, HealthStar, EMBASE, PsycINFO) to identify articles published between 1985 and 2009. We manually searched reference lists and relevant journals and used forward citation …
Ruthenium Complexes As Dna Photonucleases In Treatment Of Malignant Skin Carcinoma, Devi Kalyan Karumanchi
Ruthenium Complexes As Dna Photonucleases In Treatment Of Malignant Skin Carcinoma, Devi Kalyan Karumanchi
All Capstone Projects
A variety of Ruthenium complexes possessing terpyridine complexes as ligands in their coordination sphere have been investigated extensively as DNA photo nucleases in vitro. This work has led to the realization that compounds of Ruthenium bind to DNA purines and that the interactions are of an unprecedented bridging variety. Owing to the molar absorptivity of these complexes in the visible region, direct cleavage of duplex DNA by these complexes requires irradiation in the range of 400-500 nm.
Although the observation of DNA photo cleavage in vitro makes these systems good candidates for further investigation, it does not provide any information …
Synthesis And Cyclic Voltammetry Of A2e, Elizabeth White, Willa Harper
Synthesis And Cyclic Voltammetry Of A2e, Elizabeth White, Willa Harper
Student Scholarship – Chemistry
As aging occurs, great exposure to light leads to the build-up of fluorescent materials called lipofuscin in the retinal pigment epithelial cells. This accumulation of lipofuscin is correlated to the progression of age related macular degeneration and other retinal dystrophies. No cure for macular degeneration has been found, so lipofuscin is of great interest. The lipofuscin has been associated with an increase in radiation intake and a loss of photoreceptors in the retina. The compound A2E is being studied in this project because it is frequently found in the lipofuscin. The goal of this project is to further characterize A2E …

Protecting Degraded Rainforests: Enhancement Of Forest Carbon Stocks Under Redd+, David P. Edwards, Brendan Fisher, Emily Boyd
Protecting Degraded Rainforests: Enhancement Of Forest Carbon Stocks Under Redd+, David P. Edwards, Brendan Fisher, Emily Boyd
Rubenstein School of Environment and Natural Resources Faculty Publications
The likely Reducing Emissions from Deforestation and Degradation (REDD+) mechanism includes strategies for the enhancement of forest carbon stocks. Recent concerns have been expressed that such enhancement, or restoration, of forest carbon could be counterproductive to biodiversity conservation, because forests are managed as "carbon farms" with the application of intensive silvicultural management that could homogenize diverse degraded rainforests. Restoration increases regeneration rates in degraded forest compared to naturally regenerating forest, and thus could yield significant financial returns for carbon sequestered. Here, we argue that such forest restoration projects are, in fact, likely to provide a number of benefits to biodiversity …
Health Benefits Of Increased Walking For Sedentary, Generally Healthy Older Adults: Using Longitudinal Data To Approximate An Intervention Trial, Paula Diehr
Paula Diehr
BACKGROUND: Older adults are often advised to walk more, but randomized trials have not conclusively established the benefits of walking in this age group. Typical analyses based on observational data may have biased results. Here, we propose a "limited-bias," more interpretable estimate of the health benefits to sedentary healthy older adults of walking more, using longitudinal data from the Cardiovascular Health Study. METHODS: The number of city blocks walked per week, collected annually, was classified as sedentary (<7 blocks per>week), somewhat active, or active (>or=28). Analysis was restricted to persons sedentary and healthy in the first 2 years. In Year …7>

Psychological Profiles In A Female Bariatric Surgery Sample, Aimee L. Donato
Psychological Profiles In A Female Bariatric Surgery Sample, Aimee L. Donato
Loma Linda University Electronic Theses, Dissertations & Projects
Morbid obesity is an epidemic. Current literature suggests that people with morbid obesity tend to show increased levels of psychological dysfunction. This is especially pertinent to the clinicians who work with morbidly obese patients who seek bariatric surgery as the method for weight control. Surgery should be performed on patients who are psychologically ready to adjust to the stringent post-operative lifestyle.
The purpose of the present study was (1) to compare two groups of bariatric patients (a White group and a non-White group) on pre-surgery measures: specific scales on the Millon Behavioral Medicine Diagnostic (MBMD), the Beck Depression Inventory II …
Comparison Of Non-Surgical And Surgical Endodontic Retreatment: A Systematic Review, Robert Corr
Comparison Of Non-Surgical And Surgical Endodontic Retreatment: A Systematic Review, Robert Corr
Loma Linda University Electronic Theses, Dissertations & Projects
Primary root canal therapy has been shown to be a predictable procedure with a high degree of success 1-4, however failures can occur after treatment. Treatment options for the preservation of teeth that have had previous endodontic treatment but demonstrate persistent disease include non-surgical (orthograde) or surgical (retrograde) endodontic retreatment, assuming the tooth is restorable, periodontally sound, and the patient desires to retain the tooth. The purpose of this study was to conduct a systematic review of the current available evidence to compare the clinical and radiographic outcomes of nonsurgical with those of surgical endodontic retreatment. Methodology began with …
Microct Study Of Critical-Sized Defects Restored With A New Rhbmp-2 Carrier, Joanne S. Kim
Microct Study Of Critical-Sized Defects Restored With A New Rhbmp-2 Carrier, Joanne S. Kim
Loma Linda University Electronic Theses, Dissertations & Projects
Introduction: Regenerating bone in critical-sized maxillofacial osseous defects remains a challenge. The utilization of recombinant human bone morphogenetic protein-2 (rhBMP-2) to form new bone has been shown to be a promising alternative to autogenous bone grafts, and the development of a carrier matrix to effectively deliver the rhBMP-2 has been identified as the critical factor necessary for the successful clinical application of rhBMP-2. The objective of this study was to perform a microCT analysis to examine the density of reconstructed bone using different rhBMP-2 carriers in critical-sized defects.
Material and Methods: Critical-sized defects (approximately 2.5 cm) were created in the …
Creating Prediction Models For Obstructive Sleep Apnea Based On Gender, Jeffrey Hwang
Creating Prediction Models For Obstructive Sleep Apnea Based On Gender, Jeffrey Hwang
Loma Linda University Electronic Theses, Dissertations & Projects
Introduction: Obstructive sleep apnea (OSA) is a common chronic disorder that is characterized by repetitive episodes of airflow cessation or reduction occurring during sleep as a result of partial or complete upper airway obstruction. These recurrent events have a tremendous impact on the cardiovascular system with a multitude of dangerous consequences. Numerous studies have been conducted determining etiological risk factors for OSA including anatomical predictors which have been observed with multiple imaging techniques. Cone beam computed tomography (CBCT) is a low-radiation mode of imaging that can be used to accurately identify anatomical landmarks and measure craniofacial relationships and airway dimensions. …

Trends In Aids-Defining And Non-Aids-Defining Malignancies Among Hiv-Infected Patients: 1989-2002, Roger Bedimo, Ray Y. Chen, Neil A. Accortt, James L. Raper, Carol Linn, Jeroan J. Allison, John Dubay, Michael S. Saag, Craig J. Hoesley
Jeroan J. Allison
In a comparison of rates of acquired immunodeficiency syndrome (AIDS)-defining malignancies (ADMs) for 1989-1996 versus 1997-2002, we found a decrease in ADMs (rate ratio, 0.31; P<.0001) and a significant increase in non-AIDS-defining malignancies (non-ADMs; rate ratio, 10.87; P<.0002). The mean CD4 cell count was lower among patients with ADMs than among those with non-ADMs. A longer duration of survival during highly active antiretroviral therapy might explain the increasing incidence of non-ADMs.

Paul Keller
A series of N,N-dialkyl-2-phenylindol-3-ylglyoxylamides bearing the halogens iodine and bromine were synthesised and their binding affinity for the peripheral benzodiazepine binding sites (PBBS) in rat kidney mitochondrial membranes were evaluated using [3H]-PK11195. Central benzodiazepine receptor (CBR) affinities were also evaluated in rat cortices using 3H-flumazenil to determine their selectivity for PBBS over CBR. The tested compounds had PBBS binding affinities (IC50) ranging from 7.86 nM to 618 nM, with all compounds showing high selectivity over the CBR (CBR IC50 > 5000 nM). Among the 12 compounds tested, those with a diethylamide group were the most potent. The highest affinity iodinated PBBS …

Undergraduate Research Opportunities Program (UROP)
Alzheimer’s disease (AD) is a neurodegenerative disorder that is characterized by memory loss and is the most common cause of dementia. It is has been hypothesized that pro-inflammatory cytokines induce the inflammation that is believed to be the cause of the neuronal death that is associated with AD. γ-aminobutyric acid (GABA) is a major inhibitory neurotransmitter in the Central Nervous System possessing membrane hyperpolarization or depolarization activities. A decline in GABA may enhance cytokine release in Alzheimer’s disease resulting in neuroinflammation. Therefore, we investigated the GABA-mediated suppression of the synergistic release of interleukin-6 (IL-6) induced by interleukin 1- (IL-1) and …

Can I Access Your Data? Privacy Management In Mhealth, Aarathi Prasad, David Kotz
Dartmouth Scholarship
Mobile health (mHealth) has become important in the field of healthcare information technology, as patients begin to use mobile medical sensors to record their daily activities and vital signs. Since their medical data is collected by their sensors, the patients may wish to control data collection and distribution, so as to protect their data and share it only when the need arises. It must be possible for patients to grant or deny access to the data on the storage unit (mobile phones or personal health records (PHR)). Thus, an efficient framework is required for managing patient consent electronically, i.e.to allow …
Thoracic Target Volume Delineation Using Various Maximum-Intensity Projection Computed Tomography Image Sets For Stereotactic Body Radiation Therapy, David A. Zamora
Thoracic Target Volume Delineation Using Various Maximum-Intensity Projection Computed Tomography Image Sets For Stereotactic Body Radiation Therapy, David A. Zamora
Dissertations & Theses (Open Access)
The motion of lung tumors during respiration makes the accurate delivery of radiation therapy to the thorax difficult because it increases the uncertainty of target position. The adoption of four-dimensional computed tomography (4D-CT) has allowed us to determine how a tumor moves with respiration for each individual patient. Using information acquired during a 4D-CT scan, we can define the target, visualize motion, and calculate dose during the planning phase of the radiotherapy process. One image data set that can be created from the 4D-CT acquisition is the maximum-intensity projection (MIP). The MIP can be used as a starting point to …
The Relationship Between The Level Of Support Group Participation And Psychosocial Factors In Prostate Cancer Patients Treated With Proton Therapy, Carol A. L. Davis
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 …
High Pressure Liquid Chromatography Studies Of The Reaction Of Platinum Complexes With Peptides, Khaja Muneeruddin
High Pressure Liquid Chromatography Studies Of The Reaction Of Platinum Complexes With Peptides, Khaja Muneeruddin
Masters Theses & Specialist Projects
Platinum complexes (cisplatin, carboplatin and oxaliplatin) are effective anticancer agents. However the major drawbacks of platinum chemotherapy are toxic side effects and resistance. The affinity of platinum complexes to sulfur donor ligands of side chains of methionine and cysteine amino acids was assumed to be responsible for toxicity and resistance. Recently, it was found that the reaction of platinum complex with proteins containing sulfur donor ligands could actually favor its anticancer activity. Copper transporter 1 (Ctr 1), a protein involved in the transport of copper into the cell, also helps in the influx of cisplatin by binding to N-terminal domain …
