kisspeptins that are encoded by kiss1 gene are now considered the key regulator of reproduction from a number of studies in mammals. In most vertebrates, a paralogue of kiss1, called kiss2, is also present, and the functional significance of kisspeptins is not known precisely. In the present study, we have cloned kiss2 from a perciform teleost, the red(More)
Non-synaptic interactions among neurons via extracellular electric fields may play functional roles in the CNS. Previously in a study using voltage-sensitive dye imaging, we reported characteristic membrane polarization profiles in the CA1 region of hippocampal slices during exposure to extracellular DC fields: slow monophasic polarization in somatic region(More)
This paper presents a micro-coordinate measuring machine (micro-CMM) for large-scale dimensional measurement of a micro-slit on a precision die coater by using a shear-mode micro-probe. A glass micro sphere with a nominal diameter of 52.3 µm was attached on one end of a tapered glass capillary tube as a probe tip ball. The micro-slit width of a slot die(More)
The zebrafish brain can continue to produce new neurons in widespread neurogenic brain regions throughout life. In contrast, neurogenesis in the adult mammalian brain is restricted to the subventricular zone (SVZ) and dentate gyrus (DG). In neurogenic regions in the adult brain, radial glial cells (RGCs) are considered to function as neural stem cells(More)
A 49-year-old man with mitochondrial disease presented with visual allesthesia, a rare and puzzling phenomenon. He was admitted for treatment because of convulsions. After the convulsions ceased, he exhibited left homonymous hemianopsia. Brain diffusion-weighted magnetic resonance imaging (MRI) showed a high-intensity area in the right occipital lobe. Both(More)
