Fibroblast growth factor (FGF) is among the most common growth factors used in cultures to maintain self-renewal and proliferative capabilities of a variety of stem cells, including neural stem cells (NSCs). However, the molecular mechanisms underlying the control by FGF have remained elusive. Studies on mutant mice of FGF receptor substrate 2α (FRS2α), a(More)
Thalamocortical (TC) connectivity is reorganized by thalamic inputs during postnatal development; however, the dynamic characteristics of TC reorganization and the underlying mechanisms remain unexplored. We addressed this question using dendritic refinement of layer 4 (L4) stellate neurons in mouse barrel cortex (barrel cells) as a model; dendritic(More)
Mouse spermatogonial stem cells (SSCs) can be cultured for multiplication and maintained for long periods while preserving their spermatogenic ability. Although the cultured SSCs, named germline stem (GS) cells, are targets of genome modification, this process remains technically difficult. In the present study, we tested TALEN and double-nicking(More)
Pseudomonas aeruginosa MTB-1 does not degrade gamma-hexachlorocyclohexane (γ-HCH), but this bacterium persistently coexists with a γ-HCH-degrading strain, Sphingomonas sp. MM-1, in a microbial community enriched by the technical formulation of HCH. Here we report the complete MTB-1 genome sequence, with a 6.6-Mb circular chromosome.
In resource-based promiscuous mating systems, synchronous spawning of females affects competition among males and variation in the reproductive success of males. We documented the mating behavior of Japanese charr (Salvelinus leucomaenis japonicus) through an annual breeding season to examine the relationship between female spawning synchrony and male(More)
Pseudomonas sp. strain TKP does not degrade γ-hexachlorocyclohexane (γ-HCH), but it persistently coexists with the γ-HCH-degrading Sphingobium sp. strain TKS in a mixed culture enriched by γ-HCH. Here, we report the complete genome sequence of strain TKP, which consists of one circular chromosome with a size of 7 Mb.
The amago salmon, Oncorhynchus masou ishikawae, is an endemic subspecies of O. masou in Japan. Populations in the River Miya, located at the entry of Ise Bay, central Japan, represent indigenous wild populations. They have been isolated in small tributaries as a result of environmental degradation in recent decades, with some populations also partially(More)
A plug-based microfluidic system based on the principle of the light-addressable potentiometric sensor (LAPS) is proposed. The LAPS is a semiconductor-based chemical sensor, which has a free addressability of the measurement point on the sensing surface. By combining a microfluidic device and LAPS, ion sensing can be performed anywhere inside the(More)
BACKGROUND/AIMS Our aim was to identify cognitive factors affecting free recall, cued recall, and recognition tasks in patients with Alzheimer's disease (AD). SUBJECTS We recruited 349 consecutive AD patients who attended a memory clinic. METHODS Each patient was assessed using the Alzheimer's Disease Assessment Scale (ADAS) and the extended 3-word(More)
