Previous studies have shown that c-jun and neuronal nitric oxide synthase (nNOS) are both induced in injured motoneurons, but their roles in motoneuron death remain unclear. We hypothesized that nNOS might be the downstream effector of c-jun N-terminal kinase (JNK)/c-jun in avulsion-induced motoneuron death. Here, we found that brachial root-avulsion(More)
With a home-made jitter data processing board and microcomputer for recording extracellular single fiber action potential (SF-AP), variations of the time intervals of the SF-AP pairs, or the jitters, from two adjacent muscle fibers in the unique motor unit in tibialis' anterior in response to repeated stimuli were measured. The jitter distribution of 936(More)
Reciprocal hybridizations between Helicoverpa armigera (Hübner) and Helicoverpa assulta (Guenée) were studied. The cross between females of H. armigera and males of H. assulta yielded only fertile males and sterile individuals lacking an aedeagus, valva or ostium bursae. A total of 492 larvae of the F1 generation were obtained and 374 of these completed(More)
