Spinal proinflammatory cytokines are powerful pain-enhancing signals that contribute to pain following peripheral nerve injury (neuropathic pain). Recently, one proinflammatory cytokine, interleukin-1, was also implicated in the loss of analgesia upon repeated morphine exposure (tolerance). In contrast to prior literature, we demonstrate that the action of(More)
A case of neurogenic arthrogryposis multiplex congenita (AMC) with associated neuronal migration abnormalities is described. A child with neurogenic AMC and developmental delay presented with late onset of seizures. The first trimester of the mother's pregnancy was marked by an episode of gastro-enteritis and the intrauterine death of a twin fetus. Computer(More)
The role of cAMP in the control of secretion from bovine adrenal chromaffin cells was examined using the adenylate cyclase activator, forskolin. Treatment of chromaffin cells with forskolin resulted in a rise in cAMP levels. Forskolin inhibited catecholamine release elicited by carbamylcholine or nicotine but had no effect on secretion evoked by 55 mM K+.(More)
Two forms of vitamin C are recognized, ascorbic acid and dehydro-ascorbic acid. Although most of the vitamin exists as ascorbic acid, both forms appear to be utilized similarly by the human (Sabry et al., 1958). Many species of animals are able to synthesize ascorbic acid and do not require it in the diet. When deprived of a dietary source of vitamin C for(More)
In four experiments the effects of serial compound conditioning on responding to a trace-conditioned CS were evaluated using a fear conditioning paradigm. The subjects were 18- and 25-day-old Sprague-Dawley rats, previously shown to exhibit little or no trace fear conditioning. Here, animals as young as 18 days of age were shown to be capable of trace(More)

Electrical Engineering (ABSTRACT) In a conventional electronic ballast for a fluorescent lamp, inductor-capacitor-transformer tank circuit is used. A Piezoelectric Transformer (PT) can potentially be used to replace such a tank circuit to save space and cost. In the past, ballast design using a PT requires selecting a PT from available samples which are(More)
