A sedentary lifestyle is a contributing factor to chronic diseases, and it is often correlated with obesity. To promote an increase in physical activity, we created a social computer game, Fish'n'Steps, which links a player’s daily foot step count to the growth and activity of an animated virtual character, a fish in a fish tank. As further encouragement,(More)
The associative model of morphine tolerance predicts that established tolerance should be attenuated, i.e., extinguished, by placebo injections in the former morphine injection environment. The present study examined the effect of placebo sessions, with and without accompanying nociceptive stimulation, on the extinction of analgesic tolerance. In Experiment(More)
Recent research has shown that rats exposed to repeated stress display enhanced morphine analgesia. This study examined the possible contribution of classically conditioned analgesia to this effect. First, drug-naive rats exposed to nine daily sessions of stress, each consisting of a single 45-s exposure to footshock, subsequently displayed enhanced(More)
A high-performance liquid chromatographic (HPLC) system has been developed for the determination of nicotine and cotinine in allergenic extracts of tobacco leaf. This analysis showed eight allergenic extracts of tobacco (leaf and Mix) to have markedly different nicotine patterns. Cotinine, a photodegradation product of nicotine, was not detected.
There are classic anecdotes in the wearable computer community with mixed messages for privacy. Steve Mann has talked about sending photos via his wireless wearable from the grocery store to discuss the produce with his wife, although his camera might be transmitting images of people with the vegetables. MIT Media Lab wearables researchers (including Thad(More)
The main degradative pathway of tricarbocyanine dyes in aerated solutions is demonstrated to be a photooxidation; using sensitization techniques and specific quenchers, this reaction is established to proceed via singlet oxygen for a part, and the site at which this species attacks the polymethinic skeleton is unambiguously determined. The major(More)
