Twenty-one climbers who were members of the American Ultima Thule Everest Expedition participated in a double-blind, randomized clinical trial of phenytoin prophylaxis for acute mountain sickness during the approach to the northeast ridge of Mount Everest. The study was carried out between Beijing and base camp at 16,800 feet. Time spent ascending from(More)
Cerebral visual evoked potentials (VEPs) were collected over a 1-year period from the summer of 1983 through the summer of 1984 from 16 members of the American Ultima Thule Everest Expedition at sea level and at altitudes of 7,100 ft, 16,800 ft, and 21,300 ft. VEPs in response to 100 unilateral LED flashes were processed by a modified Nicolet CA-1000(More)
The authors report a case of acute mountain sickness (AMS) experienced by a support member of the Ultima Thule Everest Expedition. The subject arrived at the 17,000-ft base camp by truck and then developed the symptoms of AMS over the following 72 hours. Flash-induced visual evoked responses (VERs), tetrapolar impedance pulmonary plethysmography, and oxygen(More)
Antimicrobial cellulose fibers and paper products are of great importance for various applications. In this work, novel core-shell antimicrobial latexes based on hydrophobic acrylate monomers and antimicrobial macromonomer (GPHGH) were successfully prepared via a seeded semi-continuous emulsion copolymerization in the presence of a cationic surfactant. The(More)
