The Strongyloides stercoralis infective larva resumes feeding and development on receipt of signals, presumably chemical, from a host. Only two of the anterior sense organs of this larva are open to the external environment. These large, paired goblet-shaped sensilla, known as amphids, are presumably, therefore, the only chemoreceptors. Using(More)
The purpose of this investigation was to determine the impact of elevated partial pressures of O(2) on the steady state concentration of nitric oxide ((*)NO) in the cerebral cortex. Rodents with implanted O(2)- and (*)NO-specific microelectrodes were exposed to O(2) at partial pressures from 0.2 to 2.8 atmospheres absolute (ATA) for up to 45 min. Elevations(More)

We hypothesized that elevated partial pressures of O(2) would increase perivascular nitric oxide (*NO) synthesis. Rodents with O(2)- and.NO-specific microelectrodes implanted adjacent to the abdominal aorta were exposed to O(2) at partial pressures from 0.2 to 2.8 atmospheres absolute (ATA). Exposures to 2.0 and 2.8 ATA O(2) stimulated neuronal (type I) NO(More)
Parasitic nematodes of the genus Strongyloides are remarkable for their ability to switch between alternative free-living developmental pathways in response to changing internal environmental conditions. After exiting the host, soil-dwelling larval stages may develop either to infectivity via 2 microbiverous stages (homogonic development) or to free-living(More)
Host recognition, contact, and skin-penetration by Strongyloides stercoralis infective larvae are crucially important behavioral functions mediating transition from free-living to parasitic life. The sensilla of the worm's anterior tip presumably play an important role in these processes. Besides the main chemosensilla, the amphids, which are of central(More)
Management of neuropathic foot ulcers in patients with diabetes (DFUs) has changed little over the past decade, and there is currently no objective method to gauge probability of successful healing. We hypothesized that studies of stem/progenitor cells (SPCs) in the early weeks of standard wound management could predict who will heal within 16 weeks. Blood(More)
Venous gas emboli (VGE) have traditionally served as a marker for decompression stress after SCUBA diving and a reduction in bubble loads is a target for precondition procedures. However, VGE can be observed in large quantities with no negative clinical consequences. The effect of exercise before diving on VGE has been evaluated with mixed results.(More)
