Neuropeptides are an important class of molecules involved in diverse aspects of metazoan development and homeostasis. Insects are ideal model systems to investigate neuropeptide functions, and the major focus of insect neuropeptide research in the last decade has been on the identification of their receptors. Despite these vigorous efforts, receptors for(More)
Ecdysteroids and juvenile hormones (JHs) are key hormones that are responsible for insect molting and metamorphosis. JH maintains the larval state and the decline of its level in the hemolymph is crucial to elicit transformation to the pupal stage; therefore, the precise control of JH biosynthesis is necessary for normal development and the initiation of(More)
Chemical bond breaking and formation during chemical reactions can be observed using "transition state spectroscopy". Comparing the measurement result of the transition state spectroscopy with the simulation result of single direct-dynamics trajectory, we have elucidated the reaction dynamics of Claisen rearrangement of allyl vinyl ether. Observed the(More)
PURPOSE To detect the epileptogenic region causing epileptic spasms in an infant with tuberous sclerosis (TS). METHODS We applied a multiple band frequency analysis to video electroencephalographic (EEG) recordings of the infant's scalp. We also performed computed tomography (CT), magnetic resonance imaging (MRI), single-photon emission computed(More)
A 7-year-old boy presented with intractable head nodding and atonic seizures since the age of 3 years and severe behavior problems unsuitable for video EEG monitoring. We performed magnetoencephalography (MEG) 4 times: before (1) corpus callosotomy, (2) left frontal cortical resection with multiple subpial transection and (3) resection of residual MEG spike(More)
Autonomic symptoms and signs rarely occur as isolated phenomena without impaired consciousness. Ictal nausea with vomiting is a rare clinical manifestation of seizures. Ictal vomiting is considered a localizing sign in patients with partial seizures of temporal origin. We encountered two patients with simple partial seizures that produced nausea with(More)
