Intraperitoneal superoxide dismutase (SOD) and catalase were used to block the toxic effects of superoxide anion (O2) and hydrogen peroxide (H2O2), associated with the production of endometriosis and inflammation in a rabbit model. In a two-part animal study, the combined instillation of SOD and catalase significantly reduced the formation of(More)
Recently, graphene and graphene-related materials have attracted a great deal of attention due their unique physical, chemical, and biocompatibility properties and to their applications in biotechnology and medicine. However, the reports on the potential toxicity of graphene oxide (GO) in biological systems are very few. The present study investigated the(More)
A high-precision examination of the hyperfine spectrum of 6LiI in comparison with 7LiI shows a shift in the iodine nuclear electric quadrupole moment that cannot be accounted for by a model in which the electric field gradient at the iodine site is assumed to depend only upon the internuclear distance between Li and I. The other hyperfine interactions are(More)
The molecular beam electric resonance technique has been used to examine the hyperfine spectrum of RbF. The Rb nuclear electric quadrupole interaction, the spin-rotation interactions, and tensor and scalar spin-spin interactions have been measured for both Rb isotopes, including their dependence on vibrational and rotational states. Transition frequencies(More)
Omphaloceles, varying widely in size and content, result from incomplete central fusion of the four somatic plates that come to form the abdominal wall. Gastroschisis, which permits the midgut to spill freely out of an otherwise properly formed abdominal wall, comes about from rupture of the cord membrane at its site of attachment to the umbilical skin. The(More)
In the decades since the advent of in situ plasma measurements on board spacecraft, the instrumentation has grown bigger, heavier, and more complex as our understanding of space plasmas improves, and our appetite for more information increases. The result is that current state-of-the art instruments may be up to several kg in mass. However, we can no longer(More)
