We have used single-channel recording techniques to investigate the properties of sodium-activated potassium channels (KNa channels) in cultured rat olfactory bulb neurons, and in large neurons in the mitral cell layer of thin slices of olfactory bulb. Ion channels highly selective for potassium over sodium and chloride, and requiring 10-180 mM internal(More)
We recorded the activity of K+ channels activated by sodium (KNa channels) in two widely used preparations, primary cell cultures prepared from neocortex, cerebellum, midbrain, brainstem and spinal cord, and Xenopus oocytes. KNa channels from all regions shared an absolute dependence on [Na+], had conductances of 140-170 pS in symmetrical 150 mM K+ and(More)
1. Single calcium-activated potassium channels (KCa channels) were recorded from membrane patches of rat olfactory bulb neurons in culture. Only one kind of KCa channel was seen, and it was present in approximately 50% of detached patches. 2. This channel, like maxi-KCa channels of other tissues, had a single-channel conductance of 270 pS, a reversal(More)
The authors report four cases of injection site reaction after intramuscular administration of haloperidol decanoate 100 mg/mL. In each case, the injection site became edematous, red, pruritic, and tender, and a palpable mass remained for up to 3 months. No systemic symptoms were reported. All four patients had previously received the 50 mg/mL haloperidol(More)
RATIONALE AND OBJECTIVES Three-dimensional (3D) real-time volume rendering has demonstrated improvements in clinical care for several areas of radiological imaging. We test whether advanced real-time rendering techniques combined with an effective user interface will allow radiologists and surgeons to improve their performance for cardiothoracic surgery(More)
Lung transplantation is the only definitive therapy for many forms of endstage lung diseases. However, the success of lung transplantation is limited by many factors: 1) Too few lungs available for transplantation due to limited donors or injury to the donor lung; 2) current methods of preservation of excised lungs do not allow extended periods of time(More)
BACKGROUND We developed an ex-vivo circuit to evaluate human lungs retrieved from non-heart-beating donors. We assessed the effect of a similar circuit on the function of transplanted rat lungs retrieved from non-heart-beating donors. METHODS One hour after death, Sprague-Dawley rat heart-lung blocks were flushed with 20 mL of cold Perfadex, stored cold(More)
