To elucidate the effect of high temperature on grain-filling metabolism, developing rice (Oryza sativa) "Nipponbare" caryopses were exposed to high temperature (33 degrees C/28 degrees C) or control temperature (25 degrees C/20 degrees C) during the milky stage. Comprehensive gene screening by a 22-K DNA microarray and differential hybridization, followed(More)
We succeeded in visualization of the primordial germ cells (PGCs) in a living Xenopus embryo. The mRNA of the reporter Venus protein, fused to the 3' untranslated region (UTR) of DEADSouth, which is a component of the germ plasm in Xenopus eggs, was microinjected into the vegetal pole of fertilized eggs and then the cells with Venus fluorescence were(More)
The Purkinje fibers are located in the ventricular walls of the heart, just beneath the endocardium and conduct excitation from the right and left bundle branches to the ventricular myocardium. Recently, anatomists succeeded in photographing the Purkinje fibers of a sheep, which clearly showed the mesh structure of the Purkinje fibers. In this study, we(More)
A large number of CD16(-) natural killer (NK) cells appear in the human endometrium after ovulation. One possible explanation for this phenomenon is recruitment from peripheral blood (PB) CD16(-) NK cells. In this study, we examined whether IL-15 is involved in postovulatory recruitment from PB CD16(-) NK cells. The IL-15 receptor alpha chain was expressed(More)
Phospholipase D (PLD) plays an important role in plants, including responses to abiotic as well as biotic stresses. A survey of the rice (Oryza sativa) genome database indicated the presence of 17 PLD genes in the genome, among which OsPLDalpha1, OsPLDalpha5, and OsPLDbeta1 were highly expressed in most tissues studied. To examine the physiological function(More)
OBJECTIVES Further metastasis should be avoided in pancreatic cancer (PC) patients for effective surgical treatment. Regulatory T cells (Foxp3CD4 T cells including CD4CD25 T cells and CD4CD25 T cells) play important roles in tumor immunity. This study aimed to investigate whether regulatory T cells participate in metastasis. METHODS Peripheral blood was(More)
Partial acid/enzymatic hydrolysis of the ␤-(1 → 3, 1 → 6)-glucan from the cell walls of the rice blast disease fungus Pyric-ularia oryzae (Magnaporthe grisea) released elicitor-active fragments that induced phytoalexin biosynthesis in suspension cultured rice cells. From the digestion of the glucan by an endo-␤-(1 → 3)-glucanase, one highly elicitor-active(More)
In ubiquitous networks, Mobile Nodes (MNs) may often suffer from performance degradation due to the following two reasons: (1) reduction of signal strength by an MN's movement and intervening objects , and (2) radio interference with other WLANs. Therefore, quick and reliable detection of the deterioration of a wireless link condition is essential for(More)
DEADSouth mRNA encoding the RNA helicase DDX25 is a component of the germ plasm in Xenopus laevis. We investigated the mechanisms underlying its specific mRNA expression in primordial germ cells (PGCs). Based on our previous findings of several microRNA miR-427 recognition elements (MREs) in the 3' untranslated region of the mRNA, we first examined whether(More)
