Autonomic oscillatory activities exist in almost every living thing and most of them are produced by rhythmic activities of the corresponding neural systems (locomotion, respiration, heart beat, etc.). This paper mathematically discusses sustained oscillations generated by mutual inhibition of the neurons which are represented by a continuous-variable model(More)
The locomotive motion in animals is produced in some central neural units, and basically no sensory signal from peripheral receptors is necessary to induce it. The rhythm generators do not only produce rhythms but also alter their frequencies and patterns. This paper presents some mathematical models of the neural rhythm generators and discusses various(More)
Binocular rivalry is an interesting phenomenon observed in the human vision. It occurs when the right and left eyes are given different stimuli (pictures). This paper describes a mathematical model which explains the mechanism of binocular rivalry. Our basic assumption is that binocular rivalry is elicited by the mutual inhibition between the right and left(More)
In this study, we examined the feasibility of using subzonal cell injection with electrofusion for interspecies somatic cell nuclear transfer (iSCNT) to produce sei whale embryos and to improve their developmental capacity by investigating the effect of osmolarity and macromolecules in the culture medium on the in vitro developmental capacity. Hybrid(More)
The present study investigated effects of three semen extenders and storage temperatures on post-thaw characteristics of Bryde's whale spermatozoa. Spermatozoa were collected from the vasa deferens of three mature Bryde's whales captured during the Japanese whale research in the north-west Pacific (May to August 2007) after death. The three semen extenders(More)
We administered interleukin (IL)-2 with mitomycin C (MMC) and 5-fluorouracil (5-FU) by hepatic arterial infusion for the treatment of liver recurrence from colorectal cancer. The regimen consisted of continuous hepatic arterial infusion of IL-2 (7 x 10(5) JRU/day)/5-FU (250 mg/day) for 4 weeks. After those 4 weeks, a weekly hepatic arterial infusion of IL-2(More)
