Significant Differences In Markers Of Oxidant Injury Between Idiopathic And Bronchopulmonary-Dysplasia-Associated Pulmonary Hypertension In Children, Kimberly B. Vera, Donald Moore, English Flack, Michael Liske, Marshall Summar

Pediatrics Faculty Publications

While oxidant stress is elevated in adult forms of pulmonary hypertension (PH), levels of oxidant stress in pediatric PH are unknown. The objective of this study is to measure F₂-isoprostanes, a marker of oxidant stress, in children with idiopathic pulmonary hypertension (IPH) and PH due to bronchopulmonary dysplasia (BPD). We hypothesized that F₂-isoprostanes in pediatric IPH and PH associated with BPD will be higher than in controls. Plasma F₂-isoprostanes were measured in pediatric PH patients during clinically indicated cardiac catheterization and compared with controls. F₂-Isoprostane levels were compared between IPH, PH due …

St Elevation: Telling Pathology From The Benign Patterns, Waleed Tallat Kayani, Henry D. Huang, Salman Bandeali, Salim S. Virani, James M. Wilson, Yochai Birnbaum

Office of the Provost

Benefits of early reperfusion in patients presenting with acute ST elevation myocardial infarction (STEMI) are well known. The American College of Cardiology / American Heart Association guidelines recommend triage decisions are made within 10 minutes of performing initial electrocardiogram (ECG). Since many patients presenting with ischemic symptoms may have ST elevation (STE) at baseline, not all STE signify transmural ischemia. Benign patterns can be easy to find in some cases. However, patients with benign STE at baseline (left ventricular hypertrophy, early repolarization pattern) may have ongoing ischemia and present with Non-ST elevation myocardial infarction (NSTEMI) or even STEMI superimposed on …

Is Less Really More?: Determining The Efficacy And Advantages Of Low Dose Chemotherapy, Natalie Toews

Senior Honors Theses

Chemotherapy is the preferred treatment for patients with breast cancer nationwide; however, the dosage and duration of this treatment have come under recent scrutiny. The efficacy of high dose chemotherapy is many times inadequate, and the adverse physical effects resulting from this regimen have a negative holistic impact on the patients. Studies suggest that low dose chemotherapy, through antiangiogenesis, affects the spread of breast cancer carcinomas and may produce less harmful side effects in relation to the heart, brain, and eyes. Thus, oncological research proposes that a low dose regimen improves the patient’s quality of life and may be an …

Electrical & Magnetic Stimulation And Health, Yiyan Li

College of Engineering: Graduate Celebration Programs

1, Introduction Most of the patients with neural diseases such as Parkinson’s disease, Stroke and Depression, cannot be cured by taking pills or conducting surgery. In contrast to the conventional therapies, physical therapies such as TMS (transcranial magnetic stimulation) (Fig. 1) and tDCS (transcranial direct current stimulation) (Fig. 2) are the most popular methods in treating neural disorders with a non-invasive way. TMS employs electromagnetic (1-3 Tesla) induction generates an Electric field suitable for neural stimulation; tDCS employs a weak current (1-2 mA) to modulate neuronal excitabilities.

Mitogen Activated Protein Kinase Phosphatase-1 Prevents The Development Of Tactile Sensitivity In A Rodent Model Of Neuropathic Pain, Christian Ndong, Russell P. Landry, Joyce A. Deleo, Edgar A. Romero-Sandoval

Dartmouth Scholarship

Neuropathic pain due to nerve injury is one of the most difficult types of pain to treat. Following peripheral nerve injury, neuronal and glial plastic changes contribute to central sensitization and perpetuation of mechanical hypersensitivity in rodents. The mitogen activated protein kinase (MAPK) family is pivotal in this spinal cord plasticity. MAPK phosphatases (MKPs) limit inflammatory processes by dephosphorylating MAPKs. For example, MKP-1 preferentially dephosphorylates p-p38. Since spinal p-p38 is pivotal for the development of chronic hypersensitivity in rodent models of pain, and p-p38 inhibitors have shown clinical potential in acute and chronic pain patients, we hypothesize that induction of …

The Immigrant Hispanic Population: Perceptions About Cultural Competency In The Healthcare Setting, Cheryl Swanson

Nursing Theses and Dissertations

Cultural competence has been reported as a means of impacting health disparities in minority populations. The Hispanic population has grown exponentially in the United States accounting for over fifty million people on the latest census report. Continued immigration by persons of Hispanic origin occurs for many reasons offering a challenge to nurses and other healthcare workers to provide culturally competent care. The majority of research on cultural competence and the immigrant Hispanic patient has been conducted from the viewpoint of the healthcare provider. Additionally, most research that has taken into account the perspective of the immigrant Hispanic patient focuses on …

Inhibition Of Injury-Induced Cell Proliferation In The Dentate Gyrus Impairs Cognitive Recovery Following Traumatic Brain Injury, Teresa Daniels

Theses and Dissertations

Traumatic brain injury (TBI) induces a robust cellular proliferative response among neural stem/progenitor cells (NS/NPCs) in the dentate gyrus of the hippocampus. This proliferative effect is thought to contribute to the innate cognitive recovery observed following TBI. Inhibition of hippocampal neurogenesis impairs cognitive function. Furthermore, enhancement of injury-induced hippocampal neurogenesis via intraventricular administration of basic fibroblast growth factor (bFGF) improves cognitive function in animals following TBI. In this experiment, we investigated the direct association between injury-induced hippocampal neurogenesis and cognitive recovery utilizing an antimitotic agent, arabinofuranosyl cytidine (Ara-C). In this study, adult rats received a moderate lateral fluid percussion injury …

Quantitative Analysis Of Multiple Charged Large Molecules In Human Or Rat Plasma Using Liquid Chromatography Tandem Mass Spectrometry, Matthew Halquist

Theses and Dissertations

Immunoassays have traditionally been employed for the determination of plasma concentration-time profiles for pharmacokinetic studies of therapeutic proteins and peptides. These ligand binding assays have high sensitivity but require significant time for antibody generation (1 to 2 years) for assay development. Despite high sensitivity, these assays suffer from cross-reactivity that can lead to inaccurate results. As an alternative to immunoassays, this dissertation was focused on the development and validation of assays that can be used for quantitative analysis of peptides or proteins in plasma using liquid chromatography tandem mass spectrometry (LC-MS/MS). Two approaches were considered for measurement of proteins and …

Ron - The Con In Colorectal Carcinoma, Shikha Tarang, J. Wang

Journal Articles: Eppley Institute

The recepteur d’origine nantais (RON) is a member of MET family of receptor tyrosine kinase (RTKs), an overexpression of which has been observed in several cancers. The expression of RON gene is required during embryonic development and also plays critical roles in regulating macrophage inflammatory response. In CRC, the overexpression of moderate RON activity contributes to their oncogenic potential by regulating several key processes such as proliferation, motility and resistance to apoptosis. Interestingly, an aberrant RON expression is often associated with the generation of several splice variants with unique transforming activities. The targeting of RON signaling pathway by the use …

Lioudyno, Matteo Broccio, Yuri Sokolov, Suhail Rasool, Jessica Wu, Michael T. Alkire, Virginia Liu, J. Ashot Kozak, Philip R. Dennison, Charles G. Glabe, Mathias Lösche, James E. Hall

Neuroscience, Cell Biology & Physiology Faculty Publications

The impact of synthetic amyloid β (1–42) (Aβ_1–42) oligomers on biophysical properties of voltage-gated potassium channels Kv 1.3 and lipid bilayer membranes (BLMs) was quantified for protocols using hexafluoroisopropanol (HFIP) or sodium hydroxide (NaOH) as solvents prior to initiating the oligomer formation. Regardless of the solvent used Aβ_1–42 samples contained oligomers that reacted with the conformation-specific antibodies A11 and OC and had similar size distributions as determined by dynamic light scattering. Patch-clamp recordings of the potassium currents showed that synthetic Aβ_1–42 oligomers accelerate the activation and inactivation kinetics of Kv 1.3 current with no significant effect …

Adult Attachment Style, Spirituality, And Religiosity Among Individuals In Treatment For Substance Use Disorders, E Gail Horton, Naelys Diaz, Michael Weiner, Tammy Malloy

Florida Public Health Review

Spirituality and religiosity are considered to be protective factors in the treatment of substance abuse. Little is known, however, about how adult attachment style may be associated with levels of spirituality and religiosity. This study explored adult at- tachment styles among individuals in inpatient treatment for substance abuse and dependence and determined if there were significant differences between spirituality and/or religiosity variables by adult attachment style within the sample. Results indicated that neither of the religiosity variables varied by attachment style, but that one of two subscales in the spirituality measure, existential purpose and meaning, did vary significantly. Specifically, differences …

Specifically, the objective was to determine if ideal smile esthetics positively influenced this age group’s perception of opposite-sex peers based on ratings of the following psychosocial characteristics: attractiveness, desire to spend time with, desire to date, and desire for a long-term relationship. Evaluators were shown digital photographs of subjects with ideal and nonideal smiles and asked to rate those 4 attributes using a visual analogue scale (VAS). The subjects’ photographs with ideal …

The Effect Of Minocycline Treatment On Cell Proliferation And Neurogenesis In The Hippocampus In Young And Aged Brains Following Traumatic Brain Injury, Ashley Harvin

Theses and Dissertations

Following traumatic brain injury, there is an enhanced cell proliferative and neurogenic response in the young adult hippocampus, which may be associated with innate cognitive recovery. However, in the aged brain, an increased level of inflammatory cell responses was observed following injury concomitant to decreased hippocampal neurogenesis and cognitive recovery in the aging population. This suggests that excessive inflammation produced in the injured aging brain has a detrimental effect on neurogenesis and cognitive function. In this study, we examined the effect of anti-inflammatory treatment with minocycline on cell proliferation and generation of new neurons in the dentate gyrus (DG) of …
