Chelation Therapy As A Treatment For Autism, Cassandra Baty, Rachel Terharr

Festival of Communities: UG Symposium (Posters)

As medical advances continue to be made, there has yet to be an effectively consistent cure to the commonly known condition, Autism. Some researchers and physicians state that by using chelation therapy, it could help cure mercury poisoning in autistic individuals who were affected by vaccines or other sources. Because of the lack of research and knowledge of chelation therapy, there has been some controversy as to the ethics of providing chelation therapy to autistic children. The families that are put through these trials are faced with high costs, and no guarantee that their child could be cured. But to …

Oxidative Stress Accumulates In Adipose Tissue During Aging And Inhibits Adipogenesis, Hannes M. Findeisen, Kevin J. Pearson, Florence Gizard, Yue Zhao, Hua Qing, Karrie L Jones, Dianne Cohn, Elizabeth B. Heywood, Rafael De Cabo, Dennis Bruemmer

Saha Cardiovascular Research Center Faculty Publications

Aging constitutes a major independent risk factor for the development of type 2 diabetes and is accompanied by insulin resistance and adipose tissue dysfunction. One of the most important factors implicitly linked to aging and age-related chronic diseases is the accumulation of oxidative stress. However, the effect of increased oxidative stress on adipose tissue biology remains elusive. In this study, we demonstrate that aging in mice results in a loss of fat mass and the accumulation of oxidative stress in adipose tissue. In vitro, increased oxidative stress through glutathione depletion inhibits preadipocyte differentiation. This inhibition of adipogenesis is at …

A Sodium Salt Of The Dimer Of Boronoterephthalic Acid Anhydride, Scott Simmons, Albert Fratini, Vladimir Benin

Chemistry Faculty Publications

The title compound, sodium bis­(6-carb­oxy-1-hy­droxy-3-oxo-1,3-dihydro-2,1-benzoxaborol-1-yl)oxidanium, Na+·C16H15B2O13-, was prepared in two steps from 2-bromo-p-xylene. Its crystal structure was determined at 140 K and has triclinic (P) symmetry. The compound presents a unique structural motif, including two units of the cyclic anhydride of boronoterephthalic acid, joined by a protonated, and thereby trivalent, oxonium center. Association in the crystal is realized by complementary hydrogen bonding of the carboxyl groups, as well as by coordination of the sodium cations to the oxygen centers on the five-membered rings.

Theoretical Investigation Of A Reported Antibiotic From The 'Miracle Tree' Moringa Oleifera, Michael Horwath, Vladimir Benin

Chemistry Faculty Publications

Moringa oleifera, sometimes called the “Miracle Tree,” has received international attention for its potential to improve health in impoverished tropical areas. In addition to high vitamin content in the leaves and pods, the tree contains compounds with antioxidant and antibacterial properties. This study focused on the theoretical investigation of the suggested structure of one antibacterial compound, “pterygospermin,” whose existence was proposed after some studies of the roots of M. oleifera. The structure of pterygospermin was first proposed by a research group working in the 1950s, but later studies have not found evidence of this compound and have instead …

Advancing technologies are enabling a shift to more proximal nodes along the continuum of pathobiology. Innovations in biomarker platforms, genomic profiling, and molecular imaging reveal the earliest stages of pathophysiology, limiting systems disruption to cells and tissues while preserving integrated organ function, enabling risk mitigation and disease prevention.  At …

Mir-21 Induced Angiogenesis Through Akt And Erk Activation And Hif-1Α Expression., Ling-Zhi Liu, Chongyong Li, Qi Chen, Yi Jing, Richard Carpenter, Yue Jiang, Hsiang-Fu Kung, Lihui Lai, Bing-Hua Jiang

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

MicroRNAs (miRNAs) are endogenous, small noncoding RNAs that play important roles in various cellular functions and tumor development. Recent studies have indicated that miR-21 is one of the important miRNAs associated with tumor growth and metastasis, but the role and molecular mechanism of miR-21 in regulating tumor angiogenesis remain to be elucidated. In this study, miR-21 was overexpressed by transfecting pre-miR-21 into human prostate cancer cells and tumor angiogenesis was assayed using chicken chorioallantoic membrane (CAM). We found that overexpression of miR-21 in DU145 cells increased the expression of HIF-1α and VEGF, and induced tumor angiogenesis. AKT and extracellular regulated …

Effect Of Animal Facility Construction On Basal Hypothalamic-Pituitary-Adrenal And Renin-Aldosterone Activity In The Rat, Hershel Raff, Eric D. Bruder, William E. Cullinan, Dana R. Ziegler, Eric P. Cohen

Biomedical Sciences Faculty Research and Publications

Nearby construction can cause subtle, but important activation of the hypothalamic-pituitary-adrenal axis in laboratory rats.

Although loud noise and intense vibration are known to alter the behavior and phenotype of laboratory animals, little is known about the effects of nearby construction. We studied the effect of a nearby construction project on the classic stress hormones ACTH, corticosterone, renin, and aldosterone in rats residing in a barrier animal facility before, for the first 3 months of a construction project, and at 1 month after all construction was completed. During some of the construction, noise and vibrations were not obvious to investigators …

Fluorine Substitutions In An Antigenic Peptide Selectively Modulate T Cell Receptor Binding In A Minimally Perturbing Manner, Kurt H. Piepenbrink, Oleg Y. Borbulevych, Ruth F. Sommese, John Clemens, Kathrynq M. Armstrong, Clare Desmond, Priscilla Do, Brian M. Baker

Food for Health: Publications

T cell receptor (TCR) recognition of antigenic peptides bound and presented by major histocompatibility complex (MHC) molecules forms the basis of the cellular immune response to pathogens and cancer. TCRs bind peptide/MHC molecules weakly and with fast kinetics, features which have hindered detailed biophysical studies of these interactions. Modified peptides resulting in enhanced TCR binding could help overcome these challenges. Further, there is considerable interest in using modified peptides with enhanced TCR binding as the basis for clinical vaccines. Here, we studied how fluorine substitutions in an antigenic peptide can selectively impact TCR recognition. Using a structure-guided design approach, we …

Muscle Plasticity And Intramuscular Signaling In The Insulin-Resistant Obese Zucker Rat, Anjaiah Katta

Theses, Dissertations and Capstones

The ability to increase skeletal muscle mass may have important implications for the treatment of insulin resistance (IR) and diabetes [1-3]. Recent data suggest that IR muscle may adapt differently than normal muscle; however, molecular mechanism(s) responsible for this finding are not well understood [4]. Herein, we investigate the molecular mechanisms underlying the skeletal muscle remodeling in the IR Obese Zucker (OZ) rat.

The OZ rat is characterized by skeletal muscle insulin resistance, hyperglycemia, and hyperlipidemia. Compared to LZ rats, our data demonstrate that soleus muscle hypertrophy was significantly attenuated in the OZ rats after 3-weeks of muscle overload and …

Dysglycemia Induces Abnormal Circadian Blood Pressure Variability, Sivarajan Kumarasamy, Kathirvel Gopalakrishnan, Dong Hyun Kim, Nader G. Abraham, William D. Johnson, Bina Joe, Alok K. Gupta

Biochemistry and Microbiology

Background: Prediabetes (PreDM) in asymptomatic adults is associated with abnormal circadian blood pressure variability (abnormal CBPV).

Hypothesis: Systemic inflammation and glycemia influence circadian blood pressure variability.

Methods: Dahl salt-sensitive (S) rats (n = 19) after weaning were fed either an American (AD) or a standard (SD) diet. The AD (high-glycemic-index, high-fat) simulated customary human diet, provided daily overabundant calories which over time lead to body weight gain. The SD (low-glycemic-index, low-fat) mirrored desirable balanced human diet for maintaining body weight. Body weight and serum concentrations for fasting glucose (FG), adipokines (leptin and adiponectin), and proinflammatory cytokines [monocyte chemoattractant protein-1 (MCP-1) …

Urban Community Gardening The Impact On Fruit And Vegetable Intake, Christina Purcell

Students Learning with Communities

Urban community gardens are local projects managed for and by members of the local community. They may be run in partnership with local authorities or as part of community development or regeneration schemes (Hale et al., 2011). The gardens exist primarily in urban areas and are often established in response to a local community's lack of open green space (Viljoen et al., 2005). The scale and format of the gardens may vary. Depending on the available land and support, urban community gardening projects can be relatively small and in Dublin they range from small disused residential gardens (Cabra Park, See …

Effects Of Xs® Energy Drink On Aerobic Exercise Capacity Of Athletes, Kevin M. Sheehan, Lynn K. Hartzler

Rhodococcus Equi Venous Catheter Infection: A Case Report And Review Of The Literature, Rosalinda Guerrero, Ashish Bhargava, Zeina Nahleh

Wayne State University Associated BioMed Central Scholarship

Abstract

Introduction

Rhodococcus equi is an animal pathogen that was initially isolated from horses and is being increasingly reported as a cause of infection in humans with impaired cellular immunity. However, this pathogen is underestimated as a challenging antagonist and is frequently considered to be a mere contaminant despite the potential for life-threatening infections. Most case reports have occurred in immunocompromised patients who have received organ transplants (for example kidney, heart, bone marrow) or those with human immunodeficiency virus infection. Infections often manifest as pulmonary involvement or soft tissue abscesses. Bacteremia related to R. equi infections of tunneled central venous …

Epigenetics As An Explanation For Phenotypic Variation In Monozygotic Twins, Marina Pomerantseva

The Science Journal of the Lander College of Arts and Sciences

The following is the introduction of this article: Researchers often use twins as natural samples to test hypotheses regarding the contribution of genetic factors to different phenotypes, especially diseases. The classical method is comparing traits in identical, or monozygotic (MZ) twins to those of dizygotic (DZ) twins. This method has had a significant impact on our current understanding of etiologic factors in many diseases which do not follow simple Mendelian law (i.e. complex diseases), including schizophrenia, bipolar disease, and major depression.

A Retinoic Acid–Dependent Checkpoint In The Development Of Cd4+ T Cell–Mediated Immunity, Karina Pino-Lagos, Yanxia Guo, Chrysothemis Brown, Matthew P. Alexander, Raúl Elgueta, Kathryn A. Bennett, Victor De Vries, Elizabeth Nowak, Rune Blomhoff, Shanthini Sockanathan, Roshantha A. Chandraratna, Ethan Dmitrovsky, Randolph J. Noelle

Dartmouth Scholarship

It is known that vitamin A and its metabolite, retinoic acid (RA), are essential for host defense. However, the mechanisms for how RA controls inflammation are incompletely understood. The findings presented in this study show that RA signaling occurs concurrent with the development of inflammation. In models of vaccination and allogeneic graft rejection, whole body imaging reveals that RA signaling is temporally and spatially restricted to the site of inflammation. Conditional ablation of RA signaling in T cells significantly interferes with CD4⁺ T cell effector function, migration, and polarity. These findings provide a new perspective of the role of …
