Cyclopropenoid fatty acids (CPFA) are unique compounds that
contain a highly strained and reactive cyclopropene ring structure.
These compounds have been shown to cause a number of toxic effects
in a variety of animals. Rainbow trout (Salmo gairdneri) have
proven to be particularly sensitive to CPFA. Studies have revealed
that...
Pseudomonas butanovora, Mycobacterium vaccae, and Nocardioides sp. CF8 utilize distinctly different butane monooxygenases (BMOs) to initiate degradation of recalcitrant chlorinated ethenes (CEs) that pollute aquifers and soils. BMO-dependent degradation of CEs such as trichloroethylene (TCE) can lead to cellular toxicities. The type and severity of TCE transformation-dependent damage can have...
A heat stable protease was identified as the cause of textural degradation in cooked arrowtooth flounder (Atheresthes stomias) muscle. Maximum proteolytic activity in the fish muscle was observed between 55°C and 60°C and myosin heavy chain appeared to be the primary substrate for the enzyme. Degradation of this myofibrillar protein...
The majority of our modern understanding of bacterial pathogenesis is based on the strategy that involves screening bacterial genomes for the presence of the genes encoding pathogenic factors, and analysis of these genes via forward and reverse genetics. Chlamydiae represent a unique group of pathogenic bacteria in which it is...
The prevalence of childhood illness requiring hospitalization establishes the need for implementation of an applied intervention to decrease levels of hospitalization-induced anxiety in pediatric patients. In addition to anxiety, levels of perceived trauma have also been linked to pre-operative pediatric patients. Child-Centered Play Therapy (CCPT) within the medical setting has...

The photolysis of the aqueous thymine system has been investigated
at 214 nm, 229 nm and 254 nm at room temperature. Products
of photolysis have been identified as hydrogen peroxide, 6-hydroxy-5-
hydroperoxy thymine and tentatively 5-hydroxy-6-hydroperoxy thymine.
These together with thymine loss, were determined quantitatively
under a variety of conditions....
Chlamydiae are obligate intracellular bacteria that infect a variety of
eukaryotic hosts and affect normal host processes. Within host cells, their
developmental cycle takes place inside non-acidified vacuoles termed inclusions. An
inclusion membrane composed primarily of secreted chlamydial synthesized proteins
called Incs encloses the inclusion. At this location, Incs have...
Seabirds are an integral component of marine ecosystems, however, because humans typically observe only snapshots of their lives at sea, our understanding of seabird foraging ecology is often limited. A more complete understanding of the ecological roles of seabirds and identification of critical foraging habitats requires the ability to follow...

The human pathogen Chlamydia trachomatis displays different phenotypes between serovars both in vivo and in vitro. The study of chlamydial biology has been hampered by the lack of a tractable genetic system. Here, chlamydial isolates with known phenotypes as well as strains generated though recombination were fully sequenced to address...
