On January 8th, 2011 tragedy struck in Tucson, Arizona. A gunman opened fire on Representative Gabrielle Giffords' "Congress on Your Corner" event, wounding thirteen and killing six ("Arizona Shooting"). Four days later, President Obama spoke to a grieving crowd at the University of Arizona's McKale Memorial Center. This study seeks...
Human cathelicidin antimicrobial peptide (CAMP/LL-37) is a cationic antimicrobial peptide that is widely expressed by myeloid and epithelial cells at the human-environment interface. It possesses broad spectrum antimicrobial capacity against bacteria, fungi and viruses. In addition to its direct antimicrobial activity, CAMP/LL-37 also attracts and recruits monocytes, neutrophils and other...
Experiments were performed to determine whether a direct
correlation exists between the growth rates of tall and dwarf peas
grown either in the light or in the dark and endogenous gibberellin
(GA) content. Three separate but related experimental approaches
were utilized: (1) the determination of possible qualitative and /or
quantitative...
A transaminase (aminotransferase, EC 2. 6. 1) was extracted and
purified approximately 148-fold from shoot tips of pea (Pisum sativum
L. cv. Alaska) seedlings and some properties of the enzyme were
determined. The purification included acetone precipitation followed
by column chromatography on hydroxylapatite.
With a-ketoglutarate as co-substrate, the acetone precipitated...
The purpose of this study is to illuminate the role,
the function, and the ironic outcome of the Victory in
Vietnam Committee's campaign pamphlet to recall Senator
Frank Church of Idaho in 1967. The VVC's political
strategy was to build credibility with the media through
the recall pamphlet. The analysis...
Continental flood basalts represent short-lived but immense blasts of mafic magma to the continental crust. The youngest and smallest continental flood basalt worldwide, the Columbia River Basalt, initiated with the eruption of the most mafic member, the Steens Basalt (~16.9 Ma). The Steens Basalt is exposed in southeast Oregon, southwest...
The aerospace industry uses chemical kinetic models when designing propulsion systems to acquire specific details about the rate of chemical reactions, heat release, and combustion stability. These models, however, are too large and stiff to be useful as they can take weeks to run computations on. The pyMARS python package...
Shoot apex senescence is defined as the collective progressive
and deteriorative processes which ultimately terminate the functional
life of the shoot apex. Senescence of shoot apices of Pisum sativum
L. 'Alaska' as measured by cessation of stem elongation was delayed
by removal of flowers and by treatment with gibberellin A₃...
