Phytochemicals Added To The Feed Of Ovariectomized Adult Rats Increase Brown Adipose Activity, Colette N. Miller, Suresh Ambati, Erica Bass, Natalie Hohos, Diane Hartzel, Emily England, Mary Anne Della-Fera, Srujana Rayalam, Clifton A. Baile

Research Day

Background: Brown adipose tissue (BAT) uncouples respiration, using lipids as an energy source while dissipating heat. Increases in BAT activity are protective against obesity, thus compounds that increase BAT activation may help prevent weight gain. Resveratrol (R) increases BAT activity by upregulating thermogenic genes. As phytochemicals have synergistic properties, our research strategy has included investigation of the efficacy of relatively low concentrations of phytochemical blends on BAT activation. Methods: Previously, we showed that R combined with genistein (G) and quercetin (Q) reduced weight gain in aged ovariectomized (OVX) female rats. In the current study, OVX rats were fed diets containing …

Social Problem-Solving Orientation And Ptsd Symptoms In Adults With Lqts Who Experienced Cardiac Events, Elizabeth A. Waldron, Stephanie H. Felgoise, Katherine L. Corvi

Research Day

Long QT Syndrome (LQTS) is a genetic condition affecting 1:2500, predisposing individuals to cardiac arrhythmias (Ellis et al., 2009). Life threatening symptoms are unpredictable though physical exertion, emotional upset, and sleep are known triggers. Severity of symptoms and psychological factors predict development of PTSD symptoms for other cardiac diseases (Whitehead et al., 2006). Effects of LQTS-related events have not been studied. Individuals with PTSD show poorer problem solving compared to those without PTSD (Sutherland & Bryant, 2008). Problem orientation is comprised of the cognitive-emotional schemas reflective of the approaches towards problem-solving ability, general life appraisals, and beliefs (D’Zurilla et al., …

Ponatinib-Induced Adverse Effects: Thrombocytopenia, Pancreatitis And Hepatoxicity-- A Case Report, Saba Hasan, Crystal Fedorkiv, Naba Rahman, Jennifer Andres

Research Day

Abstract: Chronic myeloid leukemia (CML) is a myeloproliferative disease that generates from malignant transformation of pluripotent hematopoietic stem cells. First line treatment for CML is the tyrosine kinase inhibitor (TKI), imatinib. For patients resistant or intolerant to imatinib, other TKIs, dasatinib, nilotinib, and ponatinib, are approved treatments. Patients who are resistant or intolerant to other agents are started on ponatinib as a last line option. Common adverse events of ponatinib are hypertension, dry skin, rash, abdominal pain, constipation, and nausea. More serious adverse effects include cardiovascular effects, fluid retention, pancreatitis, severe myelosuppression, and hepatotoxicity. Treatment for these adverse effects can …

Insulin Pump Class: Back To The Basics Of Pump Therapy, Sara Wilson Reece, Cheryl Williams

Research Day

Insulin pump therapy is a common mechanism for insulin delivery in Type 1 diabetes mellitus as well as in some patients with Type 2 diabetes mellitus. At the Longstreet Clinic, approximately 3% of patients on insulin therapy utilize insulin pumps. After several patients on insulin pump therapy experienced severe hypoglycemic episodes while driving, the need for review of insulin pump survival skills were identified. The insulin pump class which was conducted in a small group setting reviewed all of the necessary survival skills for effective insulin pump therapy. Pre- and post-class hemoglobin A1c values and emergency room visits as well …

Mitoquinone (Mitoq) Exerts Antioxidant Effects Independent Of Mitochondrial Targeted Effects In Phorbol-12-Myristate-13-Acetate (Pma) Or N-Formyl-L-Methiony-L-Leucyl-L-Phenylalanine (Fmlp) Stimulated Polymorphonuclear Leukocyte (Pmn) Superoxide (So) Release, Matthew Lepera, D. Pesikan, J. Voeun, Kerry-Anne Perkins, Qian Chen, Robert J. Barsotti, Lindon H. Young

Research Day

MitoQ is a mitochondrial-targeted coenzyme Q antioxidant analog that dose-dependently restored cardiac function and reduced infarct size in isolated perfused rat hearts subjected to ischemia reperfusion (I/R). Moreover, mitoQ also dose-dependently attenuated PMA stimulated PMN superoxide (SO) release at the same concentration (10uM) as the cardioprotective dose. NADPH oxidase is the principle source of PMN SO release. We speculate that mitoQ may exert antioxidant effects independent of the mitochondria. Therefore, we hypothesized that inhibition of mitoQ on PMN-SO release will be similar as other coenzyme Q analogs: coenzyme Q1 and decylubiquinone without affecting cell viability. SO release was measured spectrophotometrically …

Gp91ds-Tat, A Selective Nadph Oxidase Peptide Inhibitor, Increases Blood Nitric Oxide (No) Bioavailability In Bind Limb Ischemia And Reperfusion (I/R), Sydney Walker, Tyler Galbreath, Qian Chen, Robert J. Barsotti, H. Patel, William Chau, Lindon H. Young

Research Day

I/R injury induces cell death and organ dysfunction in part due to a burst of reactive oxygen species that occurs upon the reintroduction of oxygen into the ischemic area, leading to endothelial dysfunction: decreased blood NO and increased hydrogen peroxide (H2O2 ) levels. We’ve previously shown in isolated rat hearts subjected to I/R injury, gp91ds-tat attenuated cardiac contractile dysfunction and reduced infarct size compared to controls presumably by the inhibition of NADPH oxidase induced superoxide release. Superoxide can quench NO via the formation of peroxynitrite and also be converted to H2O2 in blood. We attempted to confirm this hypothesis using …

Modeling Mglur1 Mediated Synaptic Depression In Cerebellar Purkinje Cells, Yizhen Su, Huo Lu

Research Day

In our previous study, we have successfully simulated mGluR1 mediated sEPSP based on experimental and is associated with parallel fiber – Purkinje cell LTD [1, 2, 3]. Recent studies have shown that the mGluR1 mediated sEPSP is generated by calcium signaling through the TRPC channel which is crucial in cerebellar LTD induction [4]. Behavior study using mutant mice that lack this type of LTD has shown no motor learning impairment [5]. We hypothesize that cerebellar TRPC mediated synaptic depression shifts the excitatory and inhibitory balance to down regulate ongoing simple-spike activity. To test our hypothesis we modified our previous model …

Anterior Cervical Foraminotomy: Short Term Outcomes In Patients With Isolated Cervical Radiculopathy, Howard Eisenbrock, Mark Rivkin, Amir R. Dehdashti

Research Day

Intro: Anterior cervical foraminotomy (ACF) is a novel approach involving direct decompression of nerve from an offending agent without fusion. Historically, several anterior and posterior approaches were utilized to treat cervical radiculopathy. Anterior cervical discectomy necessitates fusion and is subject to adjacent segment disease as well as loss of ROM. Posterior laminoforaminotomy seldom allows for removal of disc fragment and is associated with higher postoperative pain.

Methods: Between May 2010 and March 2013, 16 patients with one or two level cervical spondylosis with radiculopathy without myelopathy who failed conservative therapies such as anti-inflammatory medications, physical therapy or injections underwent anterior …

Kyphotic Progression After Thoracolumbar Burst Fractures Treated Conservatively, With Mis, Or Via Open Approach, Mark Rivkin, Howard Eisenbrock

Research Day

Management of thoracolumbar burst fractures (AO A3) without neurological deficit is subject to debate in the literature. While TLICS provides guidance for injuries necessitating intervention, it makes little mention of best surgical approaches. Furthermore, intact patients with suspected posterior ligamentous complex injury (TLICS 4) compose an additional level of management uncertainty. Present study examined outcomes for TL burst fractures in neurologically intact patients with suspected disruption of the PLC treated with bracing, MIS, or open fixation and fusion.

A Program Evaluation Of A Housing With Services Project For Low-Income Adults In Portland, Oregon, Jack A. Phillips, Paula C. Carder, Diana White

Student Research Symposium

Reducing hospital use and connecting individuals to local available services and supports are key features of the Affordable Care Act. Adult residents of public housing tend to experience worse health outcomes than other adults. Poor self-rated health and high rates of emergency department use and hospitalization among these residents have prompted efforts to improve health outcomes. Even among residents living independently, prior research indicates that health and social disparities can be effectively addressed through coordinated care and improved access to health and social services.

Cedar Sinai Park—a nonprofit residential care organization located in Portland, Oregon—will implement a demonstration project attempting …

Evaluation Of Echogenic Material On Transvenous Leads By Transesophageal Echocardiography In Patients With And Without Lead-Associated Endocarditis, Toshimasa Okabe, Md, Praveen Mehrotra, Md, Henry Siu, Md, Arnold J. Greenspon, Md

Division of Cardiology Faculty Papers

Echogenic material (EM) on non-infected leads in patients with cardiac implantable device is common on transesophageal echocardiography (TEE). Although several morphologic characteristics of EM are more commonly seen in transvenous lead-associated endocarditis, these characteristics alone are not diagnostic for lead-associated endocardiatis. Lead-associated EM on TEE should be interpreted within the overall clinical context.

The Effect Of Telephone Follow-Up On Pain Experienced By Patients After Knee Replacement Surgery, Laurie J. Jones

Evidence-Based Practice Project Reports

Hospital length of stays are decreasing throughout the U.S. in an effort to contain healthcare costs, but these measures can be detrimental to patients. Those who get knee replacement surgery are finding their length of stay reduced from an average of 3 to 4 days to 24 to 48 hours, which can affect pain control and interfere with rehabilitation and recovery. This affects many people, as more than 632,000 knee replacements occur each year (American Academy of Orthopedic Surgeons, 2008). The purpose of this evidence-based project was to evaluate the effect of telephone follow-up on pain experienced by knee replacement …

Microbial Exposure And Asthma: Applying Strachan’S Hygiene Hypothesis To Nursing Practice, Elisabeth M. Campbell

Senior Honors Theses

The incidence of asthma has risen significantly in recent decades. Asthma is a complex disease process affected by multiple factors including environmental exposure, genetics, epigenetics, and lifestyle. In 1989, the hygiene hypothesis was proposed based on Strachan’s findings suggesting increased exposure to microbes may have protective benefits against allergic rhinitis and eczema. Since that time, research in this arena has exploded as investigators seek to establish a causal link between increased microbial exposure and decreased incidence of allergic disease. The aim of this literature review is to synthesize the current research regarding Strachan’s hygiene hypothesis and identify the nursing implications …

Anti-Mitogenic Effects Of Bitter Taste Receptor (Btr) Agonists On Human Airway Smooth Muscle Cells, Deepak A. Deshpande, Phd

Center for Translational Medicine Faculty Papers

Abstract

Rationale: Obstructive diseases of airways such as asthma and COPD are characterized by airway remodeling. Clinical studies and animal models have demonstrated that ASM mass is increased in asthma, and ASM thickness is correlated with severity of the disease. Current asthma medications control inflammation and reverse airway obstruction effectively, yet have very limited effects in deterring airway remodeling. Recently we identified the expression of BTRs on human ASM cells. Activation with known BTR agonists resulted in elevation of intracellular calcium, membrane hyperpolarization and ASM relaxation. Aerosol challenge in normal and allergen sensitized- and challenged- mice resulted in a robust …

Adrenergic Signaling Regulates Mitochondrial Ca(2+) Uptake Through Pyk2-Dependent Tyrosine Phosphorylation Of The Mitochondrial Ca(2+) Uniporter., Jin O-Uchi, Bong Sook Jhun, Shangcheng Xu, Stephen Hurst, Anna Raffaello, Xiaoyun Liu, Bing Yi, Huiliang Zhang, Polina Gross, Jyotsna Mishra, Alina Ainbinder, Sarah Kettlewell, Godfrey L Smith, Robert T Dirksen, Wang Wang, Rosario Rizzuto, Shey-Shing Sheu

Center for Translational Medicine Faculty Papers

Abstract Aims: Mitochondrial Ca(2+) homeostasis is crucial for balancing cell survival and death. The recent discovery of the molecular identity of the mitochondrial Ca(2+) uniporter pore (MCU) opens new possibilities for applying genetic approaches to study mitochondrial Ca(2+) regulation in various cell types, including cardiac myocytes. Basal tyrosine phosphorylation of MCU was reported from mass spectroscopy of human and mouse tissues, but the signaling pathways that regulate mitochondrial Ca(2+) entry through posttranslational modifications of MCU are completely unknown. Therefore, we investigated α1-adrenergic-mediated signal transduction of MCU posttranslational modification and function in cardiac cells. Results: α1-adrenoceptor (α1-AR) signaling translocated activated proline-rich …

Health Care Information Technology: Securing The Electronic Health Record With Biometric Technology, Alyssa Iacona

The Review: A Journal of Undergraduate Student Research

The principal focus of this paper is to examine the integration of biometric technology into healthcare’s information technology systems. Biometric technology, a rapidly evolving mechanism, analyzes specific anatomical and physiological features of an individual for identity verification (Perrin, 2002). Moreover, as the federal government has mandated all health records to be electronic in 2014, the implementation of biometrics has become a prevalent means of security. In an effort to adhere to the patient privacy laws authorized by the Health Insurance Portability and Accountability Act (HIPAA), biometric recognition is currently used to restrict access to verified health care providers and detect …

Does Cariogenic Streptococcus Mutans Play A Role In Cardiovascular Disease?, Brittany Burks

The Review: A Journal of Undergraduate Student Research

The link that exists between oral health and the entire well-being of the body is continuously becoming more emphasized. As illnesses such as cardiovascular disease become more prevalent, dentists and researchers have suggested that a link between the transfer of bacteria in the mouth into the blood stream plays a direct cause in onset of the disease in some patients. The American Dental Association has begun stressing the importance of preventive care techniques and also the importance of understanding the role the mouth plays in a multitude of processes that occur in the body. Streptococcus mutans, which is the …

A Randomized Controlled Trial Of Nonoperative Treatment Versus Open Reduction And Internal Fixation For Stable, Displaced, Partial Articular Fractures Of The Radial Head: The Rambo Trial, Wendy Bruinsma, Izaäk Kodde, Robert Jan De Muinck Keizer, Peter Kloen, Anneluuk Lindenhovius, Jos Vroemen, Robert Haverlag, Michel Van Den Bekerom, Hugo Bolhuis, Pieter Bullens, Sven Meylaerts, Peer Van Der Zwaal, Philip Steller, Michiel Hageman, David Ring, Dennis Den Hartog, Eric Hammacher, Graham King, George Athwal, Ken Faber, Darren Drosdowech, Ruby Grewal, J. Carel Goslings, Niels Schep, Denise Eygendaal

Bone and Joint Institute

Background: The choice between operative or nonoperative treatment is questioned for partial articular fractures of the radial head that have at least 2 millimeters of articular step-off on at least one radiograph (defined as displaced), but less than 2 millimeter of gap between the fragments (defined as stable) and that are not associated with an elbow dislocation, interosseous ligament injury, or other fractures. These kinds of fractures are often classified as Mason type-2 fractures. Retrospective comparative studies suggest that operative treatment might be better than nonoperative treatment, but the long-term results of nonoperative treatment are very good. Most experts agree …

Medial Temporal Lobe Roles In Human Path Integration, Naohide Yamamoto, John W. Philbeck, Adam J. Woods, Daniel A. Gajewski, Joeanna C. Arthur, Samuel J. Potolicchio, Lucien M. Levy, Anthony J. Caputy

Neurological Surgery Faculty Publications

Path integration is a process in which observers derive their location by integrating self-motion signals along their locomotion trajectory. Although the medial temporal lobe (MTL) is thought to take part in path integration, the scope of its role for path integration remains unclear. To address this issue, we administered a variety of tasks involving path integration and other related processes to a group of neurosurgical patients whose MTL was unilaterally resected as therapy for epilepsy. These patients were unimpaired relative to neurologically intact controls in many tasks that required integration of various kinds of sensory self-motion information. However, the same …
