Rice (Oryza sativa) allelic sugary1 (sug1) mutants defective in isoamylase 1 (ISA1) accumulate varying levels of starch and phytoglycogen in their endosperm, and the activity of a pullulanase-type of a debranching enzyme (PUL) was found to correlate closely with the severity of the sug1 phenotype. Thus, three PUL-deficient mutants were generated to(More)
Cells of a developing embryo integrate a complex array of local and long-range signals that act in concert with cell-intrinsic determinants to influence developmental decisions. To systematically investigate the effects of molecular microenvironments on cell fate decisions, we developed an experimental method based on parallel exposure of cells to diverse(More)
Three mammalian Period (Per) genes, termed Per1, Per2, and Per3, have been identified as structural homologues of the Drosophila circadian clock gene, period (per). The three Per genes are rhythmically expressed in the suprachiasmatic nucleus (SCN), the central circadian pacemaker in mammals. The phases of peak mRNA levels for the three Per genes in the SCN(More)
Dravet syndrome is an intractable epileptic syndrome beginning in the first year of life. De novo mutations of SCN1A, which encode the Na(v)1.1 neuronal voltage-gated sodium channel, are considered the major cause of Dravet syndrome. In this study, we investigated genetic modifiers of this syndrome. We performed a mutational analysis of all coding exons of(More)
The purpose of this study was to demonstrate the characteristics of the Instrumental Activities of Daily Living (IADL) ability, evaluated by the Assessment of Motor and Process Skills (AMPS), and everyday memory functions (the memory necessary for daily life), assessed by the Rivermead Behavioral Memory Test (RBMT) in elderly people with dementia compared(More)
Forward genetics is a powerful approach used to link genotypes and phenotypes, and mutant screening/analysis has provided deep insights into many aspects of plant physiology. Gravitropism is a tropistic response in plants, in which hypocotyls and stems sense the direction of gravity and grow upward. Previous studies of gravitropic mutants have suggested(More)
AIM To demonstrate the characteristics of the Instrumental Activities of Daily Living (IADL), assessed by the Assessment of Motor and Process Skills (AMPS), and everyday memory functions (memory necessary function for daily life) assessed by the Rivermead Behavioral Memory Test (RBMT) in elderly people with dementia. To compare the ability and the function(More)
