We developed a bronchial provocation test (BPT) with a dry powder preparation of mannitol. The mannitol was inhaled from gelatin capsules containing 5, 10, 20, or 40 mg to a cumulative dose of 635 mg, and was delivered via an inhalator, Halermatic, or Dinkihaler device. We studied the airway sensitivity to inhaled mannitol, the repeatability of the(More)
The DØ experiment enjoyed a very successful data-collection run at the Fermilab Tevatron collider between 1992 and 1996. Since then, the detector has been upgraded to take advantage of improvements to the Tevatron and to enhance its physics capabilities. We describe the new elements of the detector, including the silicon microstrip tracker, central fiber(More)
A simple and rapid colorimetric assay for measuring the high affinity Ca2+-ATPase activity in subcellular fractions is presented. With this method a one-step addition of a malachite green/molybdate/polyvinyl alcohol reagent to the assay mixture at the end of the incubation period is all that is required for the spectrophotometric quantification of the(More)
IGFs are potent mitogens for many different cell types and play important roles in growth and development. A multitude of regulatory factors modulate the expression of IGFs. In some teleosts, liver IGF-I expression has been demonstrated to depend on the presence of GH. However, the GH dependence of IGF-II expression in teleosts is controversial. Moreover,(More)
OBJECTIVES To assess if tai chi, a traditional Chinese form of exercise, could improve proprioception in old people and if the effects of tai chi on proprioception are more evident than other exercise forms in the elderly. METHODS By detecting the threshold of passive movement, ankle and knee joint kinaesthesis was measured in 21 elderly long term tai chi(More)
OBJECTIVE The purpose of our study was to determine the prevalence, pattern, and spectrum of glenoid bone loss in anterior shoulder dislocation, to relate this to the frequency of dislocation, and to test the appropriateness of the measurement method. SUBJECTS AND METHODS Two hundred eighteen patients with single or recurrent anterior shoulder dislocation(More)
We reviewed 19 adults and 12 children who had been treated for avulsion fractures of the tibial spine. Adult injuries have not previously been reported at length; most were caused by road-traffic accidents, and 68% were associated with other injuries, of which 58% were around the knee. The higher incidence of associated injuries in adults as compared with(More)
We have identified and characterized calcium transport and the phosphorylated intermediate of the (Ca2+ + Mg2+)-ATPase in plasma membrane vesicles prepared from rat liver. The calcium transport did not absolutely require the presence of oxalate and was completely inhibited by 1 microM of ionophore A23187. Oxalate, which serves as a trapping agent in calcium(More)
This paper summarizes the current understanding on acute ankle sprain injury, which is the most common acute sport trauma, accounting for about 14% of all sport-related injuries. Among, 80% are ligamentous sprains caused by explosive inversion or supination. The injury motion often happens at the subtalar joint and tears the anterior talofibular ligament(More)
