Department of Emergency Medicine Faculty Papers

AIM: Basic fibroblast growth factor (bFGF) increases the migration and viability of bone marrow mesenchymal stem cells (MSCs) in vitro. Retrograde coronary venous infusion can provide both increased regional bFGF concentrations and homogeneous cell dissemination. We determined whether retrograde delivery of bFGF enhances the potency of transplanted MSCs for cardiac repair in a canine infarct model.

METHODS AND RESULTS: Under hypoxic conditions, cellular migration was significantly increased in MSCs co-cultured with bFGF compared to vascular endothelial growth factor or insulin-like growth factor, and bFGF promoted MSCs differentiation into a cardiomyocyte phenotype. A canine infarct model was employed by coronary ligation. …


Respiratory Function Amongst Asymptomatic Hiv Positive And Hiv Negative Clients At Aga Khan University Hospital, Nairobi, Noah Kipkemei Murbiy Jun 2015

Respiratory Function Amongst Asymptomatic Hiv Positive And Hiv Negative Clients At Aga Khan University Hospital, Nairobi, Noah Kipkemei Murbiy

Master of Medicine in Internal Medicine

Background: Spirometry is used to asses respiratory function abnormalities. This is usually in reference to a validated normal range unique to a particular gender, race, age, weight and height. Majority of persons are usually asymptomatic until the expected FEV1 has decreased by 50%. Early intervention on the abnormalities even in this asymptomatic group has been shown to retard the rate of pulmonary deterioration. An unpublished audit at the Aga Khan University Hospital, Nairobi, revealed that majority of newly diagnosed HIV positive persons were admitted at the Critical Care Units with a pulmonary cause which later resulted in poor outcomes. This …

Pannexin1 Channels Dominate Atp Release In The Cochlea Ensuring Endocochlear Potential And Auditory Receptor Potential Generation And Hearing, Jin Chen, Yan Zhu, Chun Liang, Jing Chen, Hong-Bo Zhao

Otolaryngology--Head & Neck Surgery Faculty Publications

Pannexin1 (Panx1) is a gap junction gene in vertebrates whose proteins mainly function as non-junctional channels on the cell surface. Panx1 channels can release ATP under physiological conditions and play critical roles in many physiological and pathological processes. Here, we report that Panx1 deficiency can reduce ATP release and endocochlear potential (EP) generation in the cochlea inducing hearing loss. Panx1 extensively expresses in the cochlea, including the cochlear lateral wall. We found that deletion of Panx1 in the cochlear lateral wall almost abolished ATP release under physiological conditions. Positive EP is a driving force for current through hair cells to …


Combination Of Id2 Knockdown Whole Tumor Cells And Checkpoint Blockade: A Potent Vaccine Strategy In A Mouse Neuroblastoma Model., Lina Chakrabarti, Clifford Morgan, Anthony D. Sandler Jun 2015

Combination Of Id2 Knockdown Whole Tumor Cells And Checkpoint Blockade: A Potent Vaccine Strategy In A Mouse Neuroblastoma Model., Lina Chakrabarti, Clifford Morgan, Anthony D. Sandler

Surgery Faculty Publications

Tumor vaccines have held much promise, but to date have demonstrated little clinical success. This lack of success is conceivably due to poor tumor antigen presentation combined with immuno-suppressive mechanisms exploited by the tumor itself. Knock down of Inhibitor of differentiation protein 2 (Id2-kd) in mouse neuroblastoma whole tumor cells rendered these cells immunogenic. Id2-kd neuroblastoma (Neuro2a) cells (Id2-kd N2a) failed to grow in most immune competent mice and these mice subsequently developed immunity against further wild-type Neuro2a tumor cell challenge. Id2-kd N2a cells grew aggressively in immune-compromised hosts, thereby establishing the immunogenicity of these cells. Therapeutic vaccination with Id2-kd …


The Cognition-Enhancing Effects Of Psychostimulants Involve Direct Action In The Prefrontal Cortex, Robert C. Spencer, David M. Devilbiss, Craig Berridge Jun 2015

The Cognition-Enhancing Effects Of Psychostimulants Involve Direct Action In The Prefrontal Cortex, Robert C. Spencer, David M. Devilbiss, Craig Berridge

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Psychostimulants are highly effective in the treatment of attention-deficit/hyperactivity disorder. The clinical efficacy of these drugs is strongly linked to their ability to improve cognition dependent on the prefrontal cortex (PFC) and extended frontostriatal circuit. The procognitive actions of psychostimulants are only associated with low doses. Surprisingly, despite nearly 80 years of clinical use, the neurobiology of the procognitive actions of psychostimulants has only recently been systematically investigated. Findings from this research unambiguously demonstrate that the cognition-enhancing effects of psychostimulants involve the preferential elevation of catecholamines in the PFC and the subsequent activation of norepinephrine α2 and dopamine D1 receptors. …

Department of Anesthesiology Faculty Papers

BACKGROUND: One lung ventilation (OLV) results in inflammatory and mechanical injury, leading to intraoperative and postoperative complications in children. No interventions have been studied in children to minimize such injury.

OBJECTIVE: We hypothesized that a single 2-mg·kg(-1) dose of methylprednisolone given 45-60 min prior to lung collapse would minimize injury from OLV and improve physiological stability.

METHODS: Twenty-eight children scheduled to undergo OLV were randomly assigned to receive 2 mg·kg(-1) methylprednisolone (MP) or normal saline (placebo group) prior to OLV. Anesthetic management was standardized, and data were collected for physiological stability (bronchospasm, respiratory resistance, and compliance). Plasma was assayed for …

Department of Orthopaedic Surgery Faculty Papers

Intervertebral disc (IVD) degeneration and associated low back pain (LBP) remains a major burden to our society without significant improvements in treatment strategies or patient's quality of life. While the recent cell-transplantation studies for treatment of degenerative disc disease have shown promising results, to better gauge the success and functional outcomes of these therapies, it is crucial to understand if transplanted cells give rise to healthy nucleus pulposus (NP) tissue. NP cell phenotype is unique and is defined by expression of a characteristic set of markers that reflect specialized physiology and function. This review summarizes phenotypic markers that mirror the …

Hirschsprung's disease (HSCR) is a rare congenital disease caused by impaired proliferation and migration of neural crest cells. We investigated changes in expression of microRNAs (miRNAs) and the genes they regulate in tissues of patients with HSCR. Quantitative real-time PCR and immunoblot analyses were used to measure levels of miRNA, mRNAs, and proteins in colon tissues from 69 patients with HSCR and 49 individuals without HSCR (controls). Direct interactions between miRNAs and specific mRNAs were indentified in vitro, while the function role of miR-218-1 was investigated by using miR-218 transgenic mice. An increased level of miR-218-1 correlated with increased levels …

Is Autologous Or Heterologous Pericardium Better For Valvuloplasty? A Comparative Study Of Calcification Propensity, Wen-Jian Jiang, Yong-Chao Cui, Jin-Hua Li, Xiu-Hui Zhang, Huan-Huan Ding, Yong-Qiang Lai, Hong-Jia Zhang

The Texas Heart Institute Journal

Pericardial calcification is detrimental to the long-term durability of valvuloplasty. However, whether calcification susceptibility differs between heterologous and autologous pericardium is unclear. In this study, we compared the progression of calcification in vivo between autologous and heterologous pericardium.

We randomly divided 28 rabbits into 4 equal groups. Resected rabbit pericardium served as autologous pericardium, and commercial bovine pericardium served as heterologous pericardium. We subcutaneously embedded one of each pericardial patch in the abdominal walls of 21 of the rabbits. The 7 control rabbits (group A) received no implants. The embedded samples were removed at 2 months in group B, at …


Cellular And Deafness Mechanisms Underlying Connexin Mutation-Induced Hearing Loss - A Common Hereditary Deafness, Jeffrey C. Wingard, Hong-Bo Zhao May 2015

Cellular And Deafness Mechanisms Underlying Connexin Mutation-Induced Hearing Loss - A Common Hereditary Deafness, Jeffrey C. Wingard, Hong-Bo Zhao

Otolaryngology--Head & Neck Surgery Faculty Publications

Hearing loss due to mutations in the connexin gene family, which encodes gap junctional proteins, is a common form of hereditary deafness. In particular, connexin 26 (Cx26, GJB2) mutations are responsible for ~50% of non-syndromic hearing loss, which is the highest incidence of genetic disease. In the clinic, Cx26 mutations cause various auditory phenotypes ranging from profound congenital deafness at birth to mild, progressive hearing loss in late childhood. Recent experiments demonstrate that congenital deafness mainly results from cochlear developmental disorders rather than hair cell degeneration and endocochlear potential reduction, while late-onset hearing loss results from reduction of active …

Department of Dermatology and Cutaneous Biology Faculty Papers

Pseudoxanthoma elasticum (PXE), an autosomal recessive disorder characterized by ectopic mineralization, is caused by mutations in the ABCC6 gene. We examined clinically 29 Chinese PXE patients from unrelated families, so far the largest cohort of Asian PXE patients. In a subset of 22 patients, we sequenced ABCC6 and another candidate gene, ENPP1, and conducted pathogenicity analyses for each variant. We identified a total of 17 distinct mutations in ABCC6, 15 of them being, to our knowledge, previously unreported, including 5 frameshift and 10 missense variants. In addition, a missense mutation in combination with a recurrent nonsense mutation in ENPP1 was …

Department of Orthopaedic Surgery Faculty Papers

Objectives of this study were to investigate whether AQP1 and AQP5 expression is altered during intervertebral disc degeneration and if hypoxia and HIF-1 regulate their expression in NP cells. AQP expression was measured in human tissues from different degenerative grades; regulation by hypoxia and HIF-1 was studied using promoter analysis and gain- and loss-of-function experiments. We show that both AQPs are expressed in the disc and that mRNA and protein levels decline with human disease severity. Bioinformatic analyses of AQP promoters showed multiple evolutionarily conserved HREs. Surprisingly, hypoxia failed to induce promoter activity or expression of either AQP. While genomic …

Brain iron elevation is implicated in Alzheimer's disease (AD) pathogenesis, but the impact of iron on disease outcomes has not been previously explored in a longitudinal study. Ferritin is the major iron storage protein of the body; by using cerebrospinal fluid (CSF) levels of ferritin as an index, we explored whether brain iron status impacts longitudinal outcomes in the Alzheimer's Disease Neuroimaging Initiative (ADNI) cohort. We show that baseline CSF ferritin levels were negatively associated with cognitive performance over 7 years in 91 cognitively normal, 144 mild cognitive impairment (MCI) and 67 AD subjects, and predicted MCI conversion to AD. …

Department of Cancer Biology Faculty Papers

Prostate cancer is the second leading form of cancer-related death in men. In a subset of prostate cancer patients, increased chemokine signaling IL8 and IL6 correlates with castrate-resistant prostate cancer (CRPC). IL8 and IL6 are produced by prostate epithelial cells and promote prostate cancer cell invasion; however, the mechanisms restraining prostate epithelial cell cytokine secretion are poorly understood. Herein, the cell-fate determinant factor DACH1 inhibited CRPC tumor growth in mice. Using Dach1(fl/fl)/Probasin-Cre bitransgenic mice, we show IL8 and IL6 secretion was altered by approximately 1,000-fold by endogenous Dach1. Endogenous Dach1 is shown to serve as a key endogenous restraint to …

A Novel Role For Drebrin In Regulating Progranulin Bioactivity In Bladder Cancer., Shi-Qiong Xu, Simone Buraschi, Alaide Morcavallo, Marco Genua, Tomoaki Shirao, Stephen C Peiper, Leonard G Gomella, Ruth Birbe, Antonino Belfiore, Renato V Iozzo, Andrea Morrione

Department of Urology Faculty Papers

We recently established a critical role for the growth factor progranulin in bladder cancer insofar as progranulin promotes urothelial cancer cell motility and contributes, as an autocrine growth factor, to the transformed phenotype by modulating invasion and anchorage-independent growth. In addition, progranulin expression is upregulated in invasive bladder cancer tissues compared to normal controls. However, the molecular mechanisms of progranulin action in bladder cancer have not been fully elucidated. In this study, we searched for novel progranulin-interacting proteins using pull-down assays with recombinant progranulin and proteomics. We discovered that drebrin, an F-actin binding protein, bound progranulin in urothelial cancer cells. …


The Medical Response To The Black Death, Joseph A. Legan May 2015

The Medical Response To The Black Death, Joseph A. Legan

Senior Honors Projects, 2010-2019

This paper discusses the medical response to the Black Death in both Europe and the Middle East. The Black Death was caused by a series of bacterial strands collectively known as Yersinia pestis. The Plague originated in the Mongolian Steppes. It was spread westward by the east-west trading system. Once it arrived in the Crimea in 1346, Italian merchants helped spread it throughout the Mediterranean. Medicine in Europe and the Middle East were centered on Galen’s theory of humors. There were many religious explanations for the Plague, but the main medical explanation was the spread of bad air, or …
