In the preceding paper [Maita, T., Miyanishi, T., Matsuzono, K., Tanioka, Y., & Matsuda, G. (1991) J. Biochem. 110, 68-74], we reported the amino-terminal 837-residue sequence of the heavy chain of adult chicken pectoralis muscle myosin. This paper describes the carboxyl terminal 1,097-residue sequence and the linkage of the two sequences. Rod obtained by(More)
Porcine cardiac myosin induced severe myocarditis in Lewis rats, similar to that seen after immunization with human or rat cardiac myosin. We investigated the localization of pathogenic epitopes by using porcine cardiac myosin. Subfragment-1 (S-1) and the rod were obtained by alpha-chymotryptic digestion. The rod was further fragmented by using cyanogen(More)
The kinetic relation between the photoinactivation and photooxidation of mitomycin C in the presence of riboflavin was investigated. The photoinactivation was tested for lambda-phage induction in Escherichia coli K-12 (lambda) cells and colony formation of E. coli Bs-1 cells. Mitomycin C lost its phage-inducing and antibiotic activities when the antibiotic(More)
The red nucleus (RN) is divided cytoarchitecturally into two parts, the parvicellular part (RPC) and the magnocellular part (RMC). The present study aims, first, to compare the effects of RN stimulation between low- and high-threshold afferents-evoked jaw opening reflexes (JORs), and secondly to compare the size of these effects in the RPC and RMC.(More)
This study first examines whether there is rhythmic activity of the neck muscles during cortically induced rhythmic jaw movements in rats anesthetized by urethane. Rhythmic jaw movements were induced by repetitive electrical stimulation of the orofacial motor cortex. An electromyogram in the splenius muscles (spEMG) showed rhythmic bursts during the(More)
We studied the neuronal activities of the vestibular nuclear complex (VN) neurons during rhythmic jaw movements in rats anesthetized with urethane. Rhythmic jaw movements were induced by mechanical stimulation of the palate mucosa. The firing rate of approximately 25% of VN neurons increased significantly, and that of 10% of VN neurons decreased(More)
The sequence of the NH2-terminal 830 amino acid residues of chicken cardiac ventricular muscle myosin subfragment-1 (S-1) was determined. S-1 was obtained by limited chymotryptic digestion, and cleaved into three characteristics fragments (23, 41, and 22 kDa fragments) by limited tryptic digestion. These fragments were isolated by gel filtration on a(More)
We found in a previous study that stimulation of the red nucleus (RN) facilitated the low-threshold afferent-evoked jaw-opening reflex (JOR) and suppressed the high-threshold afferent-evoked JOR. It has been reported that the RN projections to the contralateral lateral reticular nucleus (LRt), and stimulation of the LRt inhibits the nociceptive JOR. These(More)
PURPOSE OF INVESTIGATION A rare case of increasing CA 125 and CA 19-9 levels increasing in a woman with adenomyoma is described. METHODS A 39-year-old nullipara woman with CA 125 = 1,796 U/ml and CA 19-9 = 177 U/ml was submitted to abdominal and pelvic MRI, gastric endoscopy, colonoscopy, hysteroscopy, pelvic Doppler and PET scan. None of the exams(More)
We studied the effect of stimulation of the red nucleus (RN) on the jaw-opening reflex (JOR) in anesthetized rats. The JOR was evoked by electrical stimulation of the tooth pulp of a lower incisor, and was recorded as the electromyographic responses of the anterior belly of the digastric muscle, bilaterally. Conditioning electrical stimulation of the RN was(More)
