The subjects, eight girls and eight boys, were 16 to 19 year old...
Numerous tests were applied to rainbow trout
of eleven months of age to determine whether
ascorbic acid is an essential element of the diet
of these fish. Although previous work had been
done on this question, conflicts in the results,
the large reliance upon abnormal symptoms such as
lordosis and...
The first published notion that the j-function was in any way related to the Monster came in 1979, when Conway and Norton noted in [CN79] that each coefficient in the q- expansion of the j-function could be written as a (nontrivial) integral linear combination of the dimensions of irreducible representations...
Phospholipase C-β (PLC-β) isozymes are key effectors in G protein-coupled
signaling pathways. Prior research suggested that some isoforms of PLC-β may exist
and function as dimers, but little is known about dimerization of PLC-β. Data from coimmunoprecipitation
assays of differentially-tagged PLC-β constructs and sizeexclusion
chromatography of native PLC-β support homodimerization...
Ascorbic acid, or vitamin C, is well known as a co-factor for proline-hydroxylase and as an anti-oxidant. However, it is also capable of forming covalent bonds, particularly in the role of a nucleophile, henceforth termed 'ascorbylation'.
The ascorbylation of electrophiles can occur under physiological conditions. Furthermore, there are a number...
The mechanisms governing short- and long-term belowground carbon dynamics need to be understood. As part of a larger project developed to assess the effect of quantity and quality of litter inputs on the rate of soil organic matter (SOM) formation, I examined SOM in the H. J.

Phospholipase C-Jβ (PLCβ) is an important effector enzyme in G-protein-coupled
signaling pathways. Activation of PLCβ by Gα and Gβy subunits has been fairly well
characterized, but little is known about other protein interactions that may also
regulate PLCβ function. A yeast two-hybrid screen of a mouse brain cDNA library
with...
The purpose of this study was to determine if
students' school-related attitudes are significantly
affected by teacher classroom discipline management based
upon concepts contained in Judicious Discipline: A Constitutional
Perspective for School Rules (Gathercoal, 1986).
The data relative to student school-related attitudes
of elementary, middle, and high school students toward...
My thesis is comprised of two articles, titled "Journeying Through (An)Other World: Examining the Role of Magic and Transformational Otherness in Sir Gawain and the Green Knight" and "Magic, Muggles, and Mudbloods: Examining Magical Otherness in J.K. Rowling's Harry Potter Series." The introduction frames the thematic, theoretical, and critical connections...
Object oriented programming features information hiding and encapsulation, meaning that 1) each object hides the the implementation details tram access from outside and only a set of methods (interface routines) are visible outside of the object, and 2) changes to the implementation of the object do not require changes to...
The mechanisms by which the activities of phospholipase C-β (PLC-β) enzymes are negatively regulated have not been well defined. We used cardiac-derived ratmyoblast H9c2 cells to investigate possible modes of regulation of PLC-β3 enzymes,the only endogenous β isoform abundantly found in these cells. The PLC-β3population in these cells was detected...
Clostridium perfringens is the causative agent of gas gangrene and the 3rd most common cause of type A food borne disease in the United States. Critical to the pathogenicity of C. perfringens is the ability of this bacterium to produce highly resistant, metabolically dormant spores that can resume metabolic function...
