SEPARATION AND ANALYSIS OF PRESERVATIVES IN SKINCARE CREAMS BY HIGH TEMPERATURE LIQUID CHROMATOGRAPHY AND SUBCRITICAL WATER CHROMATOGRAPHY
(East Carolina University, 2011)
Preservatives are chemicals with antimicrobial activity commonly added to foods, pharmaceuticals and cosmetics in order to prolong products' shelf life and to protect the consumer from potential infection. Parabens, the ...
Characterization of Extracellular Polymeric Substances from Acidophilic Microbial Biofilms
(East Carolina University, 2010-05)
We examined the chemical composition of extracellular polymeric substances (EPS) extracted from two natural microbial pellicle biofilms growing on acid mine drainage (AMD) solutions. The EPS obtained from a mid-developmental-stage ...
KINETIC MODELING OF DISSOLUTION AND CRYSTALLIZATION OF BATCH REACTIONS WITH IN SITU SPECTROSCOPIC MEASUREMENTS
(East Carolina University, 2012)
The use of Process Analytical Technology (PAT) recommended by the Food and Drug Administration (FDA) has significantly increased during the past years in the design, control and monitoring of pharmaceutical or chemical ...
IDENTIFICATION OF NOVEL CYTOTOXIC PROSTAGLANDIN METABOLITES PRODUCED IN ARACHIDONOYL ETHANOLAMIDE-TREATED TUMOREGENIC KERATINOCYTES
(East Carolina University, 2012)
Arachidonoyl ethanolamide (AEA) induces apoptosis in mouse tumorigenic keratinocytes (JWF-2 cells). Our previous data show that AEA is metabolized by COX-2 to pro-apoptotic J-series prostaglandins. COX-2 is an enzyme that ...
Thermodynamic studies of Ca²⁺ binding to human cardiac troponin C
(East Carolina University, 2012)
Human Cardiac Troponin C (HcTnC) is an EF hand protein responsible for initiating contraction of the myocardium (heart muscle). The helix-loop-helix motif, characteristic of members of the EF-hand family, allows HcTnC to ...

This paper studies the techniques of one exceptional ESL teacher in a middle school. Five years of continuous instruction in one school with one principal is unusual for an ESL professional as teaching techniques can be ...
Adolescent Stress Induced by Family Structures and its Effect on Adult Health : A Longitudinal Assessment
(East Carolina University, 2012)
This study strives to explain the decrease in health among children and young adults in the United States in recent decades, by examining the relationship between adolescent family environments and health measures of the ...
An assessment of the polytypic status of the Namib darkling beetles Onymacris unguicularis and Onymacris rugatipennis
(2014-12-10)
The southern African beetle genus Onymacris (family Tenebrionidae) comprises 14 species, six of which are polytypic. Despite longstanding research on the physiological and behavioral adaptations of these desert beetles, ...
