The phytohormone auxin plays critical roles in the regulation of plant growth and development. Indole-3-acetic acid (IAA) has been recognized as the major auxin for more than 70 y. Although several pathways have been proposed, how auxin is synthesized in plants is still unclear. Previous genetic and enzymatic studies demonstrated that both TRYPTOPHAN(More)
The medaka Oryzias latipes and its two sister species, O. curvinotus and O. luzonensis, possess an XX-XY sex-determination system. The medaka sex-determining gene DMY has been identified on the orthologous Y chromosome [O. latipes linkage group 1 (LG1)] of O. curvinotus. However, DMY has not been discovered in other Oryzias species. These results and(More)
Nestlings of some brood parasitic birds evict hosts' eggs and young soon after hatching, thereby avoiding discrimination by hosts while monopolizing parental care. Eviction carries a cost, however, because lone parasitic nestlings attract a reduced provisioning rate. Here we describe a form of visual signaling used by the evicting Horsfield's hawk-cuckoo(More)
BACKGROUND Desmoid tumours or fibromatoses are rare entities characterized by the benign proliferation of fibroblasts, which can be life-threatening due to their locally aggressive properties. Surgery is widely accepted as the first line of treatment for extra-abdominal desmoids; however, it is not recommended for intra-abdominal desmoids because of the(More)
IAA is a naturally occurring auxin that plays a crucial role in the regulation of plant growth and development. The endogenous concentration of IAA is spatiotemporally regulated by biosynthesis, transport and its inactivation in plants. Previous studies have shown that the metabolism of IAA to 2-oxindole-3-acetic acid (OxIAA) and OxIAA-glucoside (OxIAA-Glc)(More)
OBJECTIVE To see whether stochastic resonance can be triggered in the auditory steady-state responses (ASSRs) in a magnetoencephalogram (MEG). METHODS We measured ASSRs to 1kHz sinusoidal tone modulated at 40Hz with various intensities of white noise and obtained its power and degree of phase synchrony. RESULTS Group statistics showed a significant(More)
The phytohormone auxin plays a central role in many aspects of plant growth and development. IAA is the most studied natural auxin that possesses the property of polar transport in plants. Phenylacetic acid (PAA) has also been recognized as a natural auxin for >40 years, but its role in plant growth and development remains unclear. In this study, we show(More)
In order to terminate the polymerase reaction at a desired position, a caged thymine derivative--4-O-[2-(2-nitrophenyl)propyl]thymine--was incorporated into PCR primers. In the PCR cycles, the elongation of the nascent strand (5'-->3' direction) by polymerase was site-selectively terminated at the 3'-side of T(NPP). Accordingly, predetermined protruding(More)
We performed successful coronary artery bypass grafting under cardiopulmonary bypass (CPB) in a man with beta-thalassemia. Cardiopulmonary bypass for patients with hemoglobin disorders occasionally results in fatal hematologic complications. However, taking careful precautions such as transfusing stored autologous blood and administering haptoglobin may(More)
The large GTPase dynamin is strongly accumulated in the constricted area including midzonal microtubules of dividing cells. The proline-rich domain (PRD) of dynamin has been considered as a microtubule-binding domain. However, it remains unclear how PRD controls dynamin-microtubule interaction in mitotic cells. Here, we found that the microtubule-binding(More)
