Extraction of Salvia miltiorrhiza Using Subcritical Water
(2014)Salvia miltiorrhiza, also known as Danshen, is an herb commonly used in Chinese medicine to treat cardiovascular and other diseases. As it has recently gained more recognition, this herb is currently being investigated for ... -
Insight Into the Location of DNA Xenobiotic Damage by Mass Spectrometry
(2014)Damage to DNA by a bioactivated xenobiotic typically occurs at specific sites within the genome, called hotspots. An example of this is benzo[a]-pyrene (BP), a xenobiotic that enters the body via cigarette smoking. ... -
The Duff Reaction: Researching A Modification
(2014)Formylation reactions are used to synthesize aldehydes. The Duff reaction is a formylation reaction that uses phenol derivatives, hexamethylenetetramine, acetic acid, and acid to synthesis ortho substituted aromatic ... -
Investigation of the Zinc binding region of Prothymosin-alpha : A spectroscopic and thermodynamic approach to study metal binding in Intrinsically disordered proteins
(East Carolina University, 2014)The goal of this study is to provide a deeper insight into how metals bind intrinsically disordered proteins (IDPs) by taking zinc binding to prothymosin-alpha as a case study. The involvement of metals in several diseases ... -
Electrochemical Detection of Benzo[a]Pyrene-Induced DNA Damage at TP53 Oligomers : Impact of 5'-Methyl Cytosine and Bioactivation on the Genotoxicity Process
(East Carolina University, 2014)DNA houses the blueprint that dictates how an organism will develop. However, DNA features numerous reactive sites that can be attacked by chemicals and radiation, resulting in DNA damage and possibly mutations. Chemical ... -
Fundamental and Applied Studies on Chromatographic Separation of Cold Drugs and Skincare Creams and Extraction of Salvia miltiorrhiza using Subcritical Water
(East Carolina University, 2014)Subcritical water chromatography (SBWC) and subcritical water extraction (SBWE) are two green techniques that use subcritical water as the sole solvent for separations, thus eliminating the use of toxic and expensive organic ... -
Elucidating "Consumption" : Using Fluorescent Steroid Probes to Understand Host Cholesterol Utilization by Mycobacterium spp.
(East Carolina University, 2014)Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis (TB) disease, is the leading cause of death due to bacterial infection worldwide, claiming nearly two million lives each year. Often, the immune system ... -
SPECTROSCOPIC INVESTIGATIONS OF BINDING MECHANISMS BETWEEN ANTIMICROBIAL PEPTIDES AND MODELS OF THE MEMBRANES OF PSEUDOMONAS AERUGINOSA AND KLEBSIELLA PNEUMONIAE
(East Carolina University, 2014)The wide application of antibiotics goes back over sixty years to the first use of penicillin in the mid-1940s. Antimicrobial agents have well-documented activity and have played a significant role in defending against ... -
Identification of Damaged DNA Adducts from Exposure to Benzo[a]pyrene in the TP53 Gene
(2015)Benzo[a]pyrene is a carcinogen associated with tobacco smoke that can damage DNA after it is metabolized into highly reactive forms. Identifying the resulting DNA adducts can give greater insight into the mutations that ... -
Conservation of Archaeological Wood using Non-Reducing sugars
(2015)In the conservation field there are many different thoughts on the best way to conserve waterlogged archaeological wood. The current method uses polyethylene glycol(PEG), a hydrophilic organic compound, to replace water ... -
Recognition of bacterial lipid headgroups by fluorescent crown ether-naphthalimides
(2015)The increasing incidence of antibiotic- resistant bacterial strains is a significant threat to human health. New antimicrobial mechanisms that feature reduced resistance potential are necessary to slow down the rapid ... -
A Calorimetric and Spectroscopic Study of the Interactions Between Model Lipid Membrane Bilayers and Simple Sugars
(East Carolina University, 2015)It is well known that various organisms, such as the tardigrade, naturally use carbohydrates, particularly disaccharides, to help preserve their cell structural and functional integrity during freezing or dehydration. There ... -
Investigation Into The Scope, Limitations, And Mechanistic Aspects Of A Regioselective Acylation Of Cycloplatinated Complexes
(East Carolina University, 2015)In the reaction of N-isopropyl-N-phenyl-2,2'-bipyridin-6-amine with potassium tetrachloroplatinate, the selective C-H bond activation was complicated by the low selectivity of sp² C-H bond activation in acetonitrile and ... -
Synthesis Of Non-Natural Fmoc-Protected Amino Acids To Provide Novel Fluorescent Anion Probes And Their Incorporation Into Synthetic Peptides
(East Carolina University, 2015)Cystic fibrosis is a genetic disorder caused by mutations of the cystic fibrosis transmembrane conductance regulator (CFTR) protein. CFTR serves to control the gradient of chloride and bicarbonate ions across the cellular ... -
Electrochemical Detection of Anti-Biofilm Activity Using Unnatural Amino Acid-Containing Antimicrobial Peptides
(East Carolina University, 2015)Bacterial infections are a significant health problem that can be detrimental to the human population. It is estimated that bacterial infections are responsible for billions of dollars’ worth of damages in the health care ... -
Molecular Dynamics Studies of Point Mutations of Cardiac Troponin C and Annexin
(East Carolina University, 2015)Calcium binding proteins are biologically important for their ability to convert changes in calcium ion concentration to functional changes in proteins. All calcium binding proteins use a calcium sensing motif that changes ... -
Thermodynamic and spectroscopic studies of Cd²⁺ binding to the regulatory domain and full length human cardiac troponin C (HcTnC) : elucidating plausible Cd²⁺ binding sites
(East Carolina University, 2015)Toxic metals such as cadmium (Cd²⁺) have been shown to bind to and interfere with various calcium (Ca²⁺) binding proteins including the regulatory protein cardiac troponin C (cTnC). Recent structural data has shown that ... -
