Reactive oxygen species (ROS) have been implicated in various physiological activities. However, their role in dendritic cell (DC) activation and generation has not been investigated. Using the bone marrow-derived GM-CSF-induced ex vivo DC model, we characterize how induction of ROS correlates with inflammatory DC functionality and expansion. We describe(More)
The present study describes the effects of halothane on morphine activity in the myenteric plexus-longitudinal muscle preparation of the guinea pig ileum. Morphine and halothane produced a dose-related inhibition of the electrically induced muscle contractions with IC50 of 1.9 X 10(-7) and 1.7 V/V%, respectively. The effects of morphine, but not halothane,(More)
5,6-Dimethylxanthenone-4-acetic acid (DMXAA), a potent type I interferon (IFN) inducer, was evaluated as a chemotherapeutic agent in mouse cancer models and proved to be well tolerated in human cancer clinical trials. Despite its multiple biological functions, DMXAA has not been fully characterized for the potential application as a vaccine adjuvant. In(More)
1. Electrically induced contraction of guinea pig ileum myenteric plexus-longitudinal muscle was inhibited by ketamine and halothane with IC50s of 2.1 x 10(-4) M and 1.8 v/v% respectively. 2. The inhibitory action of ketamine was partially antagonized by naloxone and the selective kappa antagonist nor-binaltorphimine. 3. The actions of ketamine and(More)
— Studies have proposed that wireless local area networks (WLAN) can be applied in medical applications to enhance the quality of patient care, such as patient monitoring systems and hospital admission systems. However, there has been concern regarding the effect of electromagnetic interference (EMI) on medical equipment from wireless communication devices,(More)
The development of live viral vaccines relies on empirically derived phenotypic criteria, especially small plaque sizes, to indicate attenuation. However, while some candidate vaccines successfully translated into licensed applications, others have failed safety trials, placing vaccine development on a hit-or-miss trajectory. We examined the determinants of(More)
The effects of morphine, fentanyl, sufentanil and droperidol on motor coordination in mice were studied. Animals were trained to complete successfully the rotarod test before assessing the effects of drugs. Administration of analgesic doses of the mu agonists morphine, fentanyl and sufentanil did not inhibit motor coordination. Droperidol produced a dose(More)
Four 11-week-old white Swiss Webster male mice were exposed to 2% enflurane in oxygen for 4 hr/day on 5 alternate days. Eight days later each male was mated with 2 females. There was a 20% loss of offspring due to stillbirths. A total of 24 pups survived (group E). At the age of 7 weeks the learning function of group E mice was tested in a Rosensweig maze(More)
The effect of halothane on prenatal development was assessed using the appearance of postnatal tolerance to the anesthetic and its effect on brain weight. Eighteen 3-month-old mice were repeatedly tested in a rotating cage for loss of righting reflex during exposure to increasing concentrations of halothane on 15 occasions to determine whether or not(More)
