Morphine For The Treatment Of Pain In Sickle Cell Disease., Mihir Gupta, Lilian Msambichaka, Samir K. Ballas, Kalpna Gupta

Cardeza Foundation for Hematologic Research

Pain is a hallmark of sickle cell disease (SCD) and its treatment remains challenging. Opioids are the major family of analgesics that are commonly used for treating severe pain. However, these are not always effective and are associated with the liabilities of their own. The pharmacology and multiorgan side effects of opioids are rapidly emerging areas of investigation, but there remains a scarcity of clinical studies. Due to opioid-induced endothelial-, mast cell-, renal mesangial-, and epithelial-cell-specific effects and proinflammatory as well as growth influencing signaling, it is likely that when used for analgesia, opioids may have organ specific pathological effects. …

Low-Density Lipoprotein Cholesterol Lowering Therapies: What Is On The Horizon?, Ramprasad Gadi, Vincent M. Figueredo, M.D.

Division of Cardiology Faculty Papers

Elevated low-density lipoprotein cholesterol (LDL-C) levels are associated with an increased risk for cardiovascular disease (CVD). Statins have been the cornerstone of lipid therapy to lower LDL-C for the past two decades, but despite significant clinical efficacy in a majority of patients, a large residual risk remains for the development of initial or recurrent atherosclerotic CVD. In addition, owing to the side-effects, a significant percentage of patients cannot tolerate any statin dose or a high enough statin dose. Thus, novel therapeutic agents are currently being developed to lower LDL-C levels further. This review will highlight these novel therapeutic agents including …

The Rehabilitative Potential Of Auditory To Visual Sensory Substitution Devices For The Blind, Naomi Perl

The Science Journal of the Lander College of Arts and Sciences

Living with a sensory impairment is challenging, and those who have lost the use of one sensory modality need to find ways to deal with numerous problems encountered in daily life. When vision is lost, these challenges include navigation through space, finding objects, recognizing people or surroundings, reading or even communicating without access to nonverbal signs provided by others such as eye gaze or facial expressions. Nevertheless, the blind manage to function efficiently in their environment, often to a surprisingly high degree. The key to this amazing phenomenon lies in the plasticity of the brain and the connections it makes …

Macular Pigment Spatial Distribution Effects On Glare Disability, Christopher Putnam, Carl Bassi

College of Optometry Faculty Works

Purpose This project explored the relationship of the macular pigment optical density (MPOD) spatial profile with measures of glare disability (GD) across the macula. Results The cHFP identified reliable MPOD spatial distribution maps demonstrating a 1st-order exponential decay as a function of increasing eccentricity. There was a significant negative correlation between both measures of foveal MPOD and GD using 6cycles per degree (cpd) and 9cpd stimuli. Significant correlations were found between corresponding parafoveal MPOD measures and GD at 2 and 4° of eccentricity using 9cpd stimuli with greater MPOD associated with less glare disability. Conclusions These results are consistent with …

Assessment Of Three Acute Responses To Traumatic Brain Injury, Shoshana Fireworker

The Science Journal of the Lander College of Arts and Sciences

Traumatic brain injury has a devastating effect on millions worldwide each year. As yet, there are no methods which have been proven to improve recovery from the trauma. Current treatment protocols revolve around reducing secondary insult, such as hypoxia, hypotension, and cerebral edema, which raises intracranial pressure. The purpose of this study is to assess the efficacy of three responses to traumatic brain injury. Two of them, the administration of hypertonic saline and the administration of progesterone, are pharmacologic, while the third, the performance of a decompressive craniectomy, is surgically invasive. A number of original studies have been analyzed to …

Two Potential Hookworm Daf-16 Target Genes, Snr-3 And Lpp-1: Gene Structure, Expression Profile, And Implications Of A Cis-Regulatory Element In The Regulation Of Gene Expression, Xin Gao, Kevin Goggin, Camille Dowling, Jason Qian, John Hawdon

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Background

Hookworms infect nearly 700 million people, causing anemia and developmental stunting in heavy infections. Little is known about the genomic structure or gene regulation in hookworms, although recent publication of draft genome assemblies has allowed the first investigations of these topics to be undertaken. The transcription factor DAF-16 mediates multiple developmental pathways in the free living nematode Caenorhabditis elegans, and is involved in the recovery from the developmentally arrested L3 in hookworms. Identification of downstream targets of DAF-16 will provide a better understanding of the molecular mechanism of hookworm infection.

Methods

Genomic Fragment 2.23 containing a DAF-16 binding …

Active Immunotherapy And Adoptive Cell Transfer As An Effective Cancer Treatment, Philip Jay Cynamon

The Science Journal of the Lander College of Arts and Sciences

There are many ways to fight cancer using the body’s own immune system. Some methods include the administration of vaccines while others involve stimulatory factors injected near tumors. One promising method is enlisting the help of T cells. To fight cancer effectively, T cells must be able to recognize cancerous antigens and the environment in which these T cells reside must be conducive to their function, survival, and proliferation. This paper discusses a method of providing such an environment called adoptive cell transfer, as well as the elements that effect this protocol and the ways in which the environment can …

Systems Level Analysis Of Systemic Sclerosis Shows A Network Of Immune And Profibrotic Pathways Connected With Genetic Polymorphisms, J. Matthew Mahoney, Jaclyn Taroni, Viktor Martyanov, Tammara A. A. Wood, Casey S. Greene, Patricia A. Pioli, Monique E. Hinchcliff, Michael L. Whitfield

Dartmouth Scholarship

Systemic sclerosis (SSc) is a rare systemic autoimmune disease characterized by skin and organ fibrosis. The pathogenesis of SSc and its progression are poorly understood. The SSc intrinsic gene expression subsets (inflammatory, fibroproliferative, normal-like, and limited) are observed in multiple clinical cohorts of patients with SSc. Analysis of longitudinal skin biopsies suggests that a patient's subset assignment is stable over 6-12 months. Genetically, SSc is multi-factorial with many genetic risk loci for SSc generally and for specific clinical manifestations. Here we identify the genes consistently associated with the intrinsic subsets across three independent cohorts, show the relationship between these genes …

Development Of Clinical Judgement For Hispanic And Non-Hispanic Nursing Students: A Comparison Of Traditional And Simulated Clinical Experiences, Eve Marie Rodriguez

Nursing Theses and Dissertations

A mixed method design evaluating for differences in students development of clinical judgment based on clinical experiences. Traditional, combination, and high fidelity simulation clinical experiences were compared. Weekly evaluations based on the Lasater Clinical Judgment Rubric were compared. Students participated in focus interviews at the completion of the study to determine perceptions of the clinical experience in terms of clinical judgment development. There were no differences based on qualitative and quantitative measures. Students in all three groups increased in clinical judgment scores and reported satisfaction in the individual clinical experience.

Child Sex Trafficking-Recognition, Intervention, And Referral: An Educational Framework To Guide Health Care Provider Practice, Cathy L. Miller

Nursing Theses and Dissertations

Awareness of the plight of children and adolescents who are sexually exploited and trafficked for financial gain has gradually garnered the attention of the public, law enforcement, and health care providers. The discussion is slowly changing to recognize these exploited children and adolescents as victims and not criminals. Marginalization of this population is slowly changing to advocacy. However, with awareness comes responsibility for the health care system to provide improved recognition, intervention, and referral of this population. Increased health care provider responsibility demands a scientifically based framework to guide the development of health care provider education programs. To date, there …

Protective Efficacy Of Centralized And Polyvalent Envelope Immunogens In An Attenuated Equine Lentivirus Vaccine, Jodi K. Craigo, Corin Ezzelarab, Sheila J. Cook, Chong Liu, David Horohov, Charles J. Issel, Ronald C. Montelaro

Maxwell H. Gluck Equine Research Center Faculty Publications

Lentiviral Envelope (Env) antigenic variation and related immune evasion present major hurdles to effective vaccine development. Centralized Env immunogens that minimize the genetic distance between vaccine proteins and circulating viral isolates are an area of increasing study in HIV vaccinology. To date, the efficacy of centralized immunogens has not been evaluated in the context of an animal model that could provide both immunogenicity and protective efficacy data. We previously reported on a live-attenuated (attenuated) equine infectious anemia (EIAV) virus vaccine, which provides 100% protection from disease after virulent, homologous, virus challenge. Further, protective efficacy demonstrated a significant, inverse, linear relationship …

Management Of Bipolar I Depression: Clinical Utility Of Lurasidone, Lillian Jan Findlay, Peggy El-Mallakh, Rif S. El-Mallakh

Nursing Faculty Publications

Lurasidone is a benzisothiazol derivative second-generation antipsychotic. It has been approved in the United States and Europe for treatment of acute schizophrenia and bipolar depression. In type I bipolar subjects, treatment with lurasidone monotherapy of adjunctive therapy to lithium or valproic acid with doses of 20 to 120 mg once daily with food, results in statistically and clinically significant reduction of depressive symptoms. Patients experience relatively few side effects, which include somnolence, akathisia, nausea, and other gastrointestinal upset. Dopamine related side effects, such as Parkinsonism and elevated prolactin, are rare and mild. Longer term safety data obtained in 6 months …

Spatial And Temporal Characteristics Of Error-Related Activity In The Human Brain, Maital Neta, Francis M. Miezin, Steven M. Nelson, Joseph W. Dubis, Nico U.F. Dosenbach, Bradley L. Schlaggar, Steven E. Petersen

Center for Brain, Biology, and Behavior: Faculty Publications

A number of studies have focused on the role of specific brain regions, such as the dorsal anterior cingulate cortex during trials on which participants make errors, whereas others have implicated a host of more widely distributed regions in the human brain. Previous work has proposed that there are multiple cognitive control networks, raising the question of whether error-related activity can be found in each of these networks. Thus, to examine error-related activity broadly, we conducted a meta-analysis consisting of 12 tasks that included both error and correct trials. These tasks varied by stimulus input (visual, auditory), response output (button …

Attentional Filtering Of Visual Information By Neuronal Ensembles In The Primate Lateral Prefrontal Cortex., Sébastien Tremblay, Florian Pieper, Adam Sachs, Julio Martinez-Trujillo

Brain and Mind Institute Researchers' Publications

The activity of neurons in the primate lateral prefrontal cortex (LPFC) is strongly modulated by visual attention. Such a modulation has mostly been documented by averaging the activity of independently recorded neurons over repeated experimental trials. However, in realistic settings, ensembles of simultaneously active LPFC neurons must generate attentional signals on a single-trial basis, despite the individual and correlated variability of neuronal responses. Whether, under these circumstances, the LPFC can reliably generate attentional signals is unclear. Here, we show that the simultaneous activity of neuronal ensembles in the primate LPFC can be reliably decoded to predict the allocation of attention …

Human Stem Cells: Is It Possible To Limit Pluripotent Human Stem Cells To Differentiate Into Specific Tissue Or Organ?, Chaya Korf

The Science Journal of the Lander College of Arts and Sciences

It would seem that differentiation of stem cells is the remedy of modern times. Yet stem cell research is more complex that the public may recognize and is still in the developmental stage. Recent breakthroughs show promise; various guidelines provide structure to this growing field but it is not ready for gross public application. The objective of this paper is to research various different methods of stem cell production and application. Methods included reviewing articles and studies to evaluate the process in production of affective stem cells. There are many therapies that illustrate this research. Upon completing and explaining this …

Current And Emerging Treatment Options For Anca-Associated Vasculitis: Potential Role Of Belimumab And Other Baff/April Targeting Agents, Aleksander Lenert, Petar Lenert

Internal Medicine Faculty Publications

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) comprises several clinical entities with diverse clinical presentations, outcomes, and nonunifying pathogenesis. AAV has a clear potential for relapses, and shows unpredictable response to treatment. Cyclophosphamide-based therapies have remained the hallmark of induction therapy protocols for more than four decades. Recently, B-cell depleting therapy with the anti-CD20 antibody rituximab has proved beneficial in AAV, leading to Food and Drug Administration approval of rituximab in combination with corticosteroids for the treatment of AAV in adults. Rituximab for ANCA-associated vasculitis and other clinical trials provided clear evidence that rituximab was not inferior to cyclophosphamide for remission …

Endovascular Stroke Therapy Results Improve Over Time: The ‘Learning Curve’ At A New Comprehensive Stoke Center, Ethan A. Benardete, Anil K. Nair

Department of Neurosurgery Faculty Papers

Background: The requirements for a comprehensive stroke center (CSC) include the capability to perform endovascular stroke therapy (EST). EST is a complex process requiring early identification of appropriate patients and effective delivery of intervention. In order to provide prompt intervention for stroke, CSCs have been established away from large academic centers in community-based hospitals. We hypothesized that quantifiable improvements would occur during the first 2 years of a community-based CSC as the processes and personnel evolved. We report the results over time of EST at a new community-based CSC. Methods: We have retrospectively analyzed demographic data and outcome metrics of …

Human Animal Chimeras For Therapeutic Protocols, Bracha Sklar

The Science Journal of the Lander College of Arts and Sciences

Research on humans is limited, therefore human animal chimeras have been used to study human systems. A Human animal chimera is an animal containing animal and human cell lines. The primary goal of human animal chimera research is to establish an animal with human cellular characters, which can and should more realistically be able to imitate as closely as possible the in vivo situations in humans. This research is very important, because it allows scientists to study human systems in vivo using a humanized animal model. However ethical issues arise when experimenting with humans and animals being mixed together. Using …

Exposure To Kynurenic Acid During Adolescence Increases Sign-Tracking And Impairs Long-Term Potentiation In Adulthood, Nicole E. Deangeli, Travis P. Todd, Stephen E. Chang, Hermes H. Yeh, Pamela W. Yeh, David J. Bucci

Dartmouth Scholarship

Changes in brain reward systems are thought to contribute significantly to the cognitive and behavioral impairments of schizophrenia, as well as the propensity to develop co-occurring substance abuse disorders. Presently, there are few treatments for persons with a dual diagnosis and little is known about the neural substrates that underlie co-occurring schizophrenia and substance abuse. One goal of the present study was to determine if a change in the concentration of kynurenic acid (KYNA), a tryptophan metabolite that is increased in the brains of people with schizophrenia, affects reward-related behavior. KYNA is an endogenous antagonist of NMDA glutamate receptors and …
