Phagocytic removal of cells undergoing apoptosis is necessary for animal development and tissue homeostasis. Draper, a homologue of the Caenorhabditis elegans phagocytosis receptor CED-1, is responsible for the phagocytosis of apoptotic cells in Drosophila, but its ligand presumably present on apoptotic cells remains unknown. An endoplasmic reticulum(More)
BACKGROUND It has been proven that the intima-media thickness (IMT) of the carotid artery increases in patients with essential hypertension. Serum levels of insulin-like growth factor-1 (IGF-1) increase in hypertensive patients with ventricular hypertrophy. However, the relationship between carotid atherosclerosis and serum levels of IGF-1 and its binding(More)
Vascular dementia (VaD) and Alzheimer's disease (AD) are the most common causes of dementia in the elderly. The aim of this study was to investigate carotid atherosclerosis, serum lipid profiles, and atherogenic hormone levels in nondiabetic Japanese men with VaD or AD. Carotid artery intima-media thickness (IMT) and plaque, serum lipid and lipoprotein(More)
We present a method of improving sound source separation using vision. The sound source separation is an essential function to accomplish auditory scene understanding by separating stream of sounds generated from multiple sound sources. By separating a stream of sounds, recognition process, such as speech recognition, can simply work on a single stream, not(More)
In this paper, we report an initial design of humanoid head platform for RoboCup humanoid challenge. While many research in RoboCup humanoid challenge naturally focus on walking and running behaviors, we focus on perception and high-level behavior issues using an upper-torso humanoid. We have designed an head/neck part of the humanoid with aesthetic design,(More)
To elucidate the actions of Draper, a receptor responsible for the phagocytic clearance of apoptotic cells in Drosophila, we isolated proteins that bind to the extracellular region of Draper using affinity chromatography. One of those proteins has been identified to be an uncharacterized protein called Drosophila melanogaster calcium-binding protein 1(More)
In this paper, we present a method of integrating auditory and visual perception for mobile robot for RoboCup. When humanoid robots are fielded for soccer game, they need to quickly react to the environment using all possible sensory inputs. While current robots heavily depends on visual inputs, auditory inputs actually play significant role in detecting(More)
