Peroxiredoxin (Prx) enzymes catalyze the reduction of hydrogen peroxide, peroxynitrous acid, and organic peroxides, and are extremely efficient peroxidases, with k[subscript cat]/K[subscript M] on the order of 10⁷ - 10⁸ M⁻¹ s⁻¹. Besides their role in oxidative stress defense, evidence has accumulated that some eukaryotes, including humans, use Prxs as...
An experimental study was made of acoustic switching of
pneumatic turbulence amplifiers. The development of fluidic devices
was generally reviewed, and the operation of the pneumatic turbulence
amplifiers made for testing was described. The characteristics
of the turbulence amplifiers were experimentally determined
and found to be typical for this type...
Recently obtained airgun-sonobuoy wide-angle refraction and
reflection profiles provide data to study crustal velocities and
structures along the continental margin of northern California and
Southern Oregon.
In the thick sedimentary wedge at the base of the continental
slope, as many as five distinct layers can be seismically observed,
which range...
Dysferlin is a ∼230 kDa terminally anchored membrane protein that is ubiquitously expressed, but is particularly enriched in skeletal and cardiac muscle tissue. Mutations covering the length of the protein have been linked to muscle wasting diseases including limb-girdle muscular dystrophy and Myoshi myopathy. Dysferlin has been shown to play...
Using a panel data set on the local telecommunications companies reporting to the FCC
for 1988-95, this paper investigates the subadditivity of the cost function, as well as
technical and allocative inefficiency of the U.S. local telephone industry. The subadditivity
test on the estimated translog cost function indicates that certain...
The Mariana Swiftlet (Aerodramus bartschi) (Aves: Apodidae) is endemic to the Mariana Islands, where it currently occurs on Saipan, Aguiguan, and Guam. An introduced population of Mariana Swiftlets is also present on O'ahu in the Hawaiian Islands. Sparing interference with the endangered population in the Marianas, the introduced, surrogate population...
The Walt Disney Company is one of the most recognizable and pervasive sources of children’s entertainment worldwide and has carefully crafted an image of childhood innocence. This wholesome image is contradicted by Disney’s consistent use of racist and sexist tropes, as well as its record of covertly using political themes...
Karl Jordan (1861-1959) was an extraordinarily productive entomologist who influenced the development of systematics, entomology, and naturalists' theoretical framework as well as their practice. He has been a figure in existing accounts of the naturalist tradition between 1890 and 1940 that have defended the relative contribution of naturalists to the...
