Here we identify a 65 kDa protein (N-WASP) from brain that binds the SH3 domains of Ash/Grb2. The sequence is homologous to Wiskott-Aldrich syndrome protein (WASP). N-WASP has several functional motifs, such as a pleckstrin homology (PH) domain and cofilin-homologous region, through which N-WASP depolymerizes actin filaments. When overexpressed in COS 7(More)
Aquatic photosynthetic organisms, including the green alga Chlamydomonas reinhardtii, induce a set of genes for a carbon-concentrating mechanism (CCM) to acclimate to CO2-limiting conditions. This acclimation is modulated by some mechanisms in the cell to sense CO2 availability. Previously, a high-CO2-requiring mutant C16 defective in an induction of the(More)
Magnetic tunnel junctions (MTJs) with ferromagnetic electrodes possessing a perpendicular magnetic easy axis are of great interest as they have a potential for realizing next-generation high-density non-volatile memory and logic chips with high thermal stability and low critical current for current-induced magnetization switching. To attain perpendicular(More)
Glutathione levels in neurons and glial cells were investigated in a neuronal-glial coculture and in separate cultures. Brain cell suspensions obtained from cerebral hemispheres of fetal rats were cultured, and after 5 days the glutathione content of this cell population, consisting mainly of neurons and astroglial cells, was 23.0 nmol/mg of cell protein,(More)
To characterize genes whose expression is induced in carbon-stress conditions, 12,969 and 13,450 5'-end expressed sequence tags (ESTs) were generated from cells grown in low-CO2 and high-CO2 conditions of the unicellular green alga, Chlamydomonas reinhardtii. These ESTs were clustered into 4436 and 3566 non-redundant EST groups, respectively. Comparison of(More)
Nerve growth factor (NGF) stimulation of pheochromocytoma PC12 cells transiently increased the intracellular concentration of reactive oxygen species (ROS). This increase was blocked by the chemical antioxidant N-acetylcysteine and a flavoprotein inhibitor, diphenylene iodonium. NGF responses of PC12 cells, including neurite outgrowth, tyrosine(More)
In order to estimate the salt and potassium intake in a population and to compare their annual trends, we developed a simple method to estimate population mean levels of 24-h urinary sodium (24HUNaV) and potassium (24HUKV) excretion from spot urine specimens collected at any time. Using 591 Japanese data items from the INTERSALT study as a gold standard, we(More)
OBJECTIVES To clarify the causes of death of residents with renal tubular dysfunction induced by cadmium (Cd) in the environment. METHODS A 15 year follow up study was performed with the inhabitants living in the Cd polluted Kakehashi River basin in Japan. Standardised mortality ratios (SMRs) for causes of death, classified by ICD-9, were computed using(More)
AIMS To characterize the adhesion molecule of Lactobacillus plantarum LA 318 that shows high adhesion to human colonic mucin (HCM). METHODS AND RESULTS The adhesion test used the BIACORE assay where PBS-washed bacterial cells showed a significant decrease in adherence to HCM than distilled water-washed cells. A component in the PBS wash fraction adhered(More)
