Anthropogenic Climate Change And Allergic Diseases, James Blando, Leonard Bielory, Viann Nguyen, Rafael Diaz, Hueiwang Anna Jeng Mar 2012

Anthropogenic Climate Change And Allergic Diseases, James Blando, Leonard Bielory, Viann Nguyen, Rafael Diaz, Hueiwang Anna Jeng

Community & Environmental Health Faculty Publications

Climate change is expected to have an impact on various aspects of health, including mucosal areas involved in allergic inflammatory disorders that include asthma, allergic rhinitis, allergic conjunctivitis and anaphylaxis. The evidence that links climate change to the exacerbation and the development of allergic disease is increasing and appears to be linked to changes in pollen seasons (duration, onset and intensity) and changes in allergen content of plants and their pollen as it relates to increased sensitization, allergenicity and exacerbations of allergic airway disease. This has significant implications for air quality and for the global food supply.


Old Remedies For Epilepsy: Avicenna's Medicine., A A Asadi-Pooya, A R Nikseresht, E Yaghoubi Mar 2012

Old Remedies For Epilepsy: Avicenna's Medicine., A A Asadi-Pooya, A R Nikseresht, E Yaghoubi

Department of Neurology Faculty Papers

BACKGROUND: The history of epilepsy and its treatments dates back to at least 4 millennia. Avicenna, c. 980 AD in Bukhara, Khorasan-1037 in Hamedan was a Persian-speaking Iranian physician, who has many recommendations and suggested various therapies for epilepsy in his book, The Canon of Medicine.

METHODS: We first reviewed the most important ancient treatments for epilepsy mentioned by Avicenna and considered those as the key words for our next step. Then, we made a literature search (medline and scopus) with those key words to find out new scientific findings in modern medicine about the Avicenna's suggestions.

RESULTS: Among the …


Krüppel-Like Factor 4 Regulates Intestinal Epithelial Cell Morphology And Polarity, Tianxin Yu, Xi Chen, Wen Zhang, Juan Li, Ren Xu, Timothy C Wang, Walden Ai, Chunming Liu Feb 2012

Krüppel-Like Factor 4 Regulates Intestinal Epithelial Cell Morphology And Polarity, Tianxin Yu, Xi Chen, Wen Zhang, Juan Li, Ren Xu, Timothy C Wang, Walden Ai, Chunming Liu

Markey Cancer Center Faculty Publications

Krüppel-like factor 4 (KLF4) is a zinc finger transcription factor that plays a vital role in regulating cell lineage differentiation during development and maintaining epithelial homeostasis in the intestine. In normal intestine, KLF4 is predominantly expressed in the differentiated epithelial cells. It has been identified as a tumor suppressor in colorectal cancer. KLF4 knockout mice demonstrated a decrease in number of goblet cells in the colon, and conditional ablation of KLF4 from the intestinal epithelium led to altered epithelial homeostasis. However, the role of KLF4 in differentiated intestinal cells and colon cancer cells, as well as the mechanism by which …

Department of Neurosurgery Faculty Papers

Background: There is convincing preclinical evidence that early decompression in the setting of spinal cord injury (SCI) improves neurologic outcomes. However, the effect of early surgical decompression in patients with acute SCI remains uncertain. Our objective was to evaluate the relative effectiveness of early (,24 hours after injury) versus late ($24 hours after injury) decompressive surgery after traumatic cervical SCI.

Methods: We performed a multicenter, international, prospective cohort study (Surgical Timing in Acute Spinal Cord Injury Study: STASCIS) in adults aged 16–80 with cervical SCI. Enrolment occurred between 2002 and 2009 at 6 North American centers. The primary outcome was …


Matrix Metalloproteinase Genes Are Transcriptionally Regulated By E2f Transcription Factors: A Link Between Cell Cycle Control And Metastatic Progression, Jacqueline Lea Johnson Feb 2012

Matrix Metalloproteinase Genes Are Transcriptionally Regulated By E2f Transcription Factors: A Link Between Cell Cycle Control And Metastatic Progression, Jacqueline Lea Johnson

USF Tampa Graduate Theses and Dissertations

The RbµE2F transcriptional regulatory pathway plays a critical role in the cell cycle. Rb is inactivated through multiple waves of phosphorylation, mediated mainly by cyclin D and cyclin E associated kinases. Once Rb is inactivated, cells can enter Sµphase. Collectively, three Rb family members and ten E2F proteins coordinate every additional stage of the cell cycle, from quiescence to mitosis. However the RbµE2F pathway is frequently altered in cancer. Aside from cell proliferation, the RbµE2F pathway regulates other essential cellular processes including apoptosis, cell differentiation, angiogenesis and DNA damage repair pathways, but its role in invasion and cancer progression is …

Center for Translational Medicine Faculty Papers

It is generally accepted that the intercalated disc (ICD) required for mechano-electrical coupling in the heart consists of three distinct junctional complexes: adherens junctions, desmosomes and gap junctions. However, recent morphological and molecular data indicate a mixing of adherens junctional and desmosomal components, resulting in a 'hybrid adhering junction' or 'area composita'. The α-catenin family member αT-catenin, part of the N-cadherin-catenin adhesion complex in the heart, is the only α-catenin that interacts with the desmosomal protein plakophilin-2 (PKP2). Thus, it has been postulated that αT-catenin might serve as a molecular integrator of the two adhesion complexes in the area composita. …


Lithium Treatment Of Appswdi/Nos2−/− Mice Leads To Reduced Hyperphosphorylated Tau, Increased Amyloid Deposition And Altered Inflammatory Phenotype, Tiffany L. Sudduth, Joan G. Wilson, Angela Everhart, Carol A. Colton, Donna M. Wilcock Feb 2012

Lithium Treatment Of Appswdi/Nos2−/− Mice Leads To Reduced Hyperphosphorylated Tau, Increased Amyloid Deposition And Altered Inflammatory Phenotype, Tiffany L. Sudduth, Joan G. Wilson, Angela Everhart, Carol A. Colton, Donna M. Wilcock

Sanders-Brown Center on Aging Faculty Publications

Lithium is an anti-psychotic that has been shown to prevent the hyperphosphorylation of tau protein through the inhibition of glycogen-synthase kinase 3-beta (GSK3β). We recently developed a mouse model that progresses from amyloid pathology to tau pathology and neurodegeneration due to the genetic deletion of NOS2 in an APP transgenic mouse; the APPSwDI/NOS2-/- mouse. Because this mouse develops tau pathology, amyloid pathology and neuronal loss we were interested in the effect anti-tau therapy would have on amyloid pathology, learning and memory. We administered lithium in the diets of APPSwDI/NOS2-/- mice for a period of eight months, followed by water maze …

Puerperal Fever From Hippocrates To Pasteur, Hunter A. Hammill Feb 2012

Puerperal Fever From Hippocrates To Pasteur, Hunter A. Hammill

Houston History of Medicine Lectures (2006-2012)

The death of a mother in childbirth leaving a newborn deserted is a sort of a desecration. This was a frequent event for early physicians. It was felt to be caused by miasmas or punishment from the gods. DaVinci felt the cause was milk stasis, Hippocrates - lochia, Virchow - weather. Then came Semmelweis, Pasteur and Lister. They started a battle with ignorance, hospital administration, budget and academic politics. Ending with the murder of Semmelweis!

Decorin-Mediated Inhibition Of Colorectal Cancer Growth And Migration Is Associated With E-Cadherin In Vitro And In Mice., Xiuli Bi, Nicole M Pohl, Zhibin Qian, George R Yang, Yuan Gou, Grace Guzman, Andre Kajdacsy-Balla, Renato V Iozzo, Wancai Yang Feb 2012

Decorin-Mediated Inhibition Of Colorectal Cancer Growth And Migration Is Associated With E-Cadherin In Vitro And In Mice., Xiuli Bi, Nicole M Pohl, Zhibin Qian, George R Yang, Yuan Gou, Grace Guzman, Andre Kajdacsy-Balla, Renato V Iozzo, Wancai Yang

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Previous studies have shown that decorin expression is significantly reduced in colorectal cancer tissues and cancer cells, and genetic deletion of the decorin gene is sufficient to cause intestinal tumor formation in mice, resulting from a downregulation of p21, p27(kip1) and E-cadherin and an upregulation of β-catenin signaling [Bi,X. et al. (2008) Genetic deficiency of decorin causes intestinal tumor formation through disruption of intestinal cell maturation. Carcinogenesis, 29, 1435-1440]. However, the regulation of E-cadherin by decorin and its implication in cancer formation and metastasis is largely unknown. Using a decorin knockout mouse model (Dcn(-/-) mice) and manipulated expression of decorin …

Direct Evidence For Inhibition Of Mitochondrial Permeability Transition Pore Opening By Sevoflurane Preconditioning In Cardiomyocytes: Comparison With Cyclosporine A., Anna Onishi, Masami Miyamae, Kazuhiro Kaneda, Junichiro Kotani, Vincent M. Figueredo

Division of Cardiology Faculty Papers

To assess whether sevoflurane preconditioning is associated with inhibition of mitochondrial permeability transition pore (MPTP), the effects of sevoflurane were compared with those of cyclosporine A, a known inhibitor of MPTP opening. Isolated perfused guinea pig hearts underwent 30 min global ischemia and 120 min reperfusion (control). Sevoflurane preconditioning was elicited by administration of 2% sevoflurane for 10 min with 10 min washout before ischemia (sevoflurane). A preconditioning-like cardioprotection was also induced by administering cyclosporine A (0.2 μM) for 15 min, starting 5 min before ischemia and for 10 min after the onset of reperfusion (cyclosporine A). Left ventricular developed …

Mechanisms Of Fetal Programming In Hypertension., John E. Jones, Julie A. Jurgens, Sarah A. Evans, Riley C. Ennis, Van Anthony Villar, Pedro A. Jose

Pediatrics Faculty Publications

Events that occur in the early fetal environment have been linked to long-term health and lifespan consequences in the adult. Intrauterine growth restriction (IUGR), which may occur as a result of nutrient insufficiency, exposure to hormones, or disruptions in placental structure or function, may induce the fetus to alter its developmental program in order to adapt to the new conditions. IUGR may result in a decrease in the expression of genes that are responsible for nephrogenesis as nutrients are rerouted to the development of more essential organs. Fetal survival under these conditions often results in low birth weight and a …

METHODS AND FINDINGS: 14 subjects with metastatic stage IV pancreatic cancer were recruited to receive an eight week cycle of intravenous ascorbic acid (three infusions per week), using a dose escalation design, along with standard treatment of gemcitabine and erlotinib. Of 14 recruited subjects enrolled, nine completed the study (three in each dosage tier). There were fifteen non-serious adverse events and eight serious adverse events, all likely related to progression of …


Inflammatory Signaling Compromises Cell Responses To Interferon Alpha., W-C Huangfu, J Qian, C Liu, J Liu, A E Lokshin, D P Baker, H Rui, S Y Fuchs Jan 2012

Inflammatory Signaling Compromises Cell Responses To Interferon Alpha., W-C Huangfu, J Qian, C Liu, J Liu, A E Lokshin, D P Baker, H Rui, S Y Fuchs

Department of Cancer Biology Faculty Papers

Interferon alpha (IFNα) is widely used for treatment of melanoma and certain other malignancies. This cytokine as well as the related IFNβ exerts potent anti-tumorigenic effects; however, their efficacy in patients is often suboptimal. Here, we report that inflammatory signaling impedes the effects of IFNα/β. Melanoma cells can secrete pro-inflammatory cytokines that inhibit cellular responses to IFNα/β via activating the ligand-independent pathway for the phosphorylation and subsequent ubiquitination and accelerated degradation of the IFNAR1 chain of type I IFN receptor. Catalytic activity of the p38 protein kinase was required for IFNAR1 downregulation and inhibition of IFNα/β signaling induced by proinflammatory …


Gabapentin In The Treatment Of Bipolar Disorder, Wendy M. Waits, Donald P. Hall Jr., M.D. Jan 2012

Gabapentin In The Treatment Of Bipolar Disorder, Wendy M. Waits, Donald P. Hall Jr., M.D.

Jefferson Journal of Psychiatry

Gabapentin, a relatively new anti-epileptic drug (AED), is emerging as a therapeutic option for treatment refractory and rapid-cycling bipolar illnesses. Pharmacotherapy for bipolar disorders traditionally involves valproate, carbamazapine, or lithium, drugs which are associated with numerous adverse effects. Conversely, gabapentin has an attractive pharmacokinetics profile and relatively few side effects. There are no large randomized controlled clinical trials to date examining gabapentin’s role in mood stabilization. However, informal reports have cited encouraging results in up to 80% of patients and general tolerance to side effects. These findings make the new drug a possible choice for patients who have failed to …

Sanders-Brown Center on Aging Faculty Publications

In order to study oxidative stress in peripheral cells of Alzheimer's disease (AD) patients, immortalized lymphocytes derived from two peculiar cohorts of patients, referring to early onset AD (EOSAD) and subjects harboured AD related mutation (ADmut), were used. Oxidative stress was evaluated measuring i) the typical oxidative markers, such as HNE Michel adducts, 3 Nitro-Tyrosine residues and protein carbonyl on protein extracts, ii) and the antioxidant capacity, following the enzymatic kinetic of superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione reductase (GRD). We found that the signs of oxidative stress, measured as oxidative marker levels, were evident only in ADmut …


Ensembles Of Human Mtl Neurons "Jump Back In Time" In Response To A Repeated Stimulus, M. W. Howard, Indre Viskontas, K. H. Shankar, I. Fried Jan 2012

Ensembles Of Human Mtl Neurons "Jump Back In Time" In Response To A Repeated Stimulus, M. W. Howard, Indre Viskontas, K. H. Shankar, I. Fried

Psychology

Episodic memory, which depends critically on the integrity of the medial temporal lobe (MTL), has been described as ‘‘mental time travel’’ in which the rememberer ‘‘jumps back in time.’’ The neural mechanism underlying this ability remains elusive. Mathematical and computational models of performance in episodic memory tasks provide a specific hypothesis regarding the computation that supports such a jump back in time. The models suggest that a representation of temporal context, a representation that changes gradually over macroscopic periods of time, is the cue for episodic recall. According to these models, a jump back in time corresponds to a stimulus …

In Ovo Serial Skeletal Muscle Diffusion Tractography Of The Developing Chick Embryo Using Dti: Feasibility And Correlation With Histology, Zien Zhou, Zachary Delproposto, Lianming Wu, Jianrong Xu, Jia Hua, Yan Zhou, Yongquan Ye, Zishu Zhang, Jiani Hu, E Mark Haacke

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Magnetic resonance imaging is a noninvasive method of evaluating embryonic development. Diffusion tensor imaging (DTI), based on the directional diffusivity of water molecules, is an established method of evaluating tissue structure. Yet embryonic motion degrades the in vivo acquisition of long-duration DTI. We used a dual-cooling technique to avoid motion artifact and aimed to investigate whether DTI can be used to monitor chick embryonic skeletal muscle development in ovo, and to investigate the correlation between quantitative DTI parameters fractional anisotropy (FA) and fiber length and quantitative histologic parameters fiber area percentage (FiberArea%) and limb length.

Recent Updates On The Role Of Micrornas In Prostate Cancer, Oudai Hassan, Aamir Ahmad, Seema Sethi, Fazlul H. Sarkar

Wayne State University Associated BioMed Central Scholarship

Abstract

MicroRNAs (miRNAs) are short non-coding RNAs that are involved in several important biological processes through regulation of genes post-transcriptionally. Carcinogenesis is one of the key biological processes where miRNAs play important role in the regulation of genes. The miRNAs elicit their effects by binding to the 3' untranslated region (3'UTR) of their target mRNAs, leading to the inhibition of translation or the degradation of the mRNA, depending on the degree of complementary base pairing. To-date more than 1,000 miRNAs are postulated to exist, although the field is moving rapidly. Currently, miRNAs are becoming the center of interest in a …

The Cyclin-Like Protein Spy1/Ringo Promotes Mammary Transformation And Is Elevated In Human Breast Cancer, Mohammad Al Sorkhy, Rosa-Maria Ferraiuolo, Espanta Jalili, Agnes Malysa, Andreea R. Fratiloiu, Bonnie F. Sloane, Lisa A. Porter

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Spy1 is a novel 'cyclin-like' activator of the G1/S transition capable of enhancing cell proliferation as well as inhibiting apoptosis. Spy1 protein levels are tightly regulated during normal mammary development and forced overexpression in mammary mouse models accelerates mammary tumorigenesis.

Methods

Using human tissue samples, cell culture models and in vivo analysis we study the implications of Spy1 as a mediator of mammary transformation and breast cancer proliferation.

Results

We demonstrate that this protein can facilitate transformation in a manner dependent upon the activation of the G2/M Cdk, Cdk1, and the subsequent inhibition of the anti-apoptotic regulator FOXO1. …

Adenovirus-36 Is Associated With Obesity In Children And Adults In Sweden As Determined By Rapid Elisa, Malin Almgren, Richard Atkinson, Jia He, Agenta Hilding, Emilia Hagman, Alicia Wolk, Anders Thorell, Claude Marcus, Erik Naslund, Claes-Goren Ostenson, Martin Schalling, Catherina Lavebratt

Pathology Publications

Background

Experimental and natural human adenovirus-36 (Adv36) infection of multiple animal species results in obesity through increasing adipogenesis and lipid accumulation in adipocytes. Presence of Adv36 antibodies detected by serum neutralization assay has previously been associated with obesity in children and adults living in the USA, South Korea and Italy, whereas no association with adult obesity was detected in Belgium/the Netherlands nor among USA military personnel. Adv36 infection has also been shown to reduce blood lipid levels, increase glucose uptake by adipose tissue and skeletal muscle biopsies, and to associate with improved glycemic control in non-diabetic individuals.

Mouse Rc/Btb2, A Member Of The Rcc1 Superfamily, Localizes To Spermatid Acrosomal Vesicles, Jiannan Wang, Maria E. Teves, Xuening Shen, David R. Nagarkatti-Gude, Rex A. Hess, Scott C. Henderson, Jerome F. Strauss Iii, Zhibing Zhang

Obstetrics and Gynecology Publications

Mouse RC/BTB2 is an unstudied protein of the RCC1 (Regulator of Chromosome Condensation) superfamily. Because of the significant remodeling of chromatin that occurs during spermiogenesis, we characterized the expression and localization of mouse RC/BTB2 in the testis and male germ cells. The Rc/btb2 gene yields two major transcripts: 2.3 kb Rc/btb2-s, present in most somatic tissues examined; and 2.5 kb Rc/btb2-t, which contains a unique non-translated exon in its 5′-UTR that is only detected in the testis. During the first wave of spermatogenesis, Rc/btb2-t mRNA is expressed from day 8 after birth, reaching highest levels of expression at day …


Redox Regulation Of Differentiation In Neuroblastoma, Anne Marie Silvis Jan 2012

Redox Regulation Of Differentiation In Neuroblastoma, Anne Marie Silvis

Theses, Dissertations and Capstones

Neuroblastoma is the most common extracranial solid tumor in childhood, ranking third in prevalence among infant cancers. Despite intensive therapy with surgery, radiation and chemotherapy, there is a high chance of tumor recurrence. These children are therefore given retinoids in the maintenance phase to differentiate the tumor cells and to avoid/lessen this incidence. Although 13-cis retinoic acid (13-cis RA) is currently used to treat neuroblastoma, there is much evidence supporting the prevalence of its metabolite, all-trans retinoic acid (ATRA), to be the main signaling retinoid in vivo.

The SK-N-SH neuroblastoma cell line, which is composed of three sub-types: sympatheoadrenal neuroblasts …


Down-Regulation Of The Transcription Factor Snail In The Placentas Of Patients With Preeclampsia And In A Rat Model Of Preeclampsia, Larissa Federova, Cara Gatto-Weis, Sleiman Smaili, Nauman Khurshid, Joseph I. Shapiro M.D., Deepak Malhorta, Terrence Horrigan Jan 2012

Down-Regulation Of The Transcription Factor Snail In The Placentas Of Patients With Preeclampsia And In A Rat Model Of Preeclampsia, Larissa Federova, Cara Gatto-Weis, Sleiman Smaili, Nauman Khurshid, Joseph I. Shapiro M.D., Deepak Malhorta, Terrence Horrigan

Biochemistry and Microbiology

Background: Placental malfunction in preeclampsia is believed to be a consequence of aberrant differentiation of trophoblast lineages and changes in utero-placental oxygenation. The transcription factor Snail, a master regulator molecule of epithelial-mesenchymal transition in embryonic development and in cancer, is shown to be involved in trophoblast differentiation as well. Moreover, Snail can be controlled by oxidative stress and hypoxia. Therefore, we examined the expression of Snail and its downstream target, e-cadherin, in human normal term, preterm and preeclamptic placentas, and in pregnant rats that developed preeclampsia-like symptoms in the response to a 20- fold increase in sodium intake.

Methods: Western …


Extraskeletal Effects Of Vitamin D: Potential Impact On Wv Disease Morbidity And Mortality, Franklin D. Shuler, Dana Lycans, Elias Salloum Jan 2012

Extraskeletal Effects Of Vitamin D: Potential Impact On Wv Disease Morbidity And Mortality, Franklin D. Shuler, Dana Lycans, Elias Salloum

Orthopaedics

Vitamin D is an essential nutrient and a secosteroid hormone that regulates many physiologic processes beyond calcium and bone homeostasis. These "extraskeletal" effects are impacted by the circulating levels of the storage form of vitamin D, 25-hydroxyvitamin D3. Levels of vitamin D can be detected after completing a simple 25(OH)D blood test. Vitamin D deficiency (< 30 ng/mL) is associated with a higher risk of many chronic diseases including, but not limited to, fourteen types of cancers, type 1 and 2 diabetes mellitus, obesity, cardiovascular disease, hypertension, stroke, and asthma. This article explores the association between vitamin D deficiency and the burden of chronic diseases in West Virginia.
