This paper reports a revised Wiener filter to resolve the inverse problem for magnetoencephalograms (MEGs) according to the structural and functional constraints based on magnetic resonance imaging (MRI) and functional magnetic resonance imaging (fMRI). Wiener filter-MEG imaging for half field stimulation with the chromatic stimulus resolved fast, slow and(More)
In order to clarify the histological aspects of arterial walls of miniature swine, 41 arterial segments removed from each of 17 Göttingen miniature swines/csk at 6-12 months after birth were examined by light microscopy. Every segment was classified into three types--elastic, transitional, and muscular--according to its histological architecture. Each type(More)
Nitric oxide (NO) generation in murine macrophages was determined in real time using the electron paramagnetic resonance (EPR) spin trapping method. An iron complex of N-methyl D-glucamine dithiocarbamate was utilized as the spin trap. This spin trapping compound reacts with NO in solution to form a specific room-temperature stable, mononitrosyl complex(More)
We addressed the strategies of mapping protein binding sites on a DNA fragment by atomic force microscopy (AFM). The protein binding site was uniquely mapped by distinguishing two termini of a linear DNA fragment. Our simple methods were found very useful to get information on transcription regulatory regions by taking advantage of long range and quick(More)
Mental sweating is human sweating that is accelerated via the sympathetic nerve by application of mental or physical stress. In the neurosciences, there is keen interest in this type of sweating, because the amount of sweat in response to a stress applied to a volunteer directly reflects activity of the sympathetic nerve. It is therefore of particular value(More)
BACKGROUND An important function of skin physiology is mental sweating, where sweating is accelerated via the sympathetic nerve by mental or physical stress externally applied to a volunteer. AIM Activity of the sympathetic nerve (ASN) is evaluated by quantitative measurement of mental sweating. MATERIAL AND METHODS Optical coherence tomography (OCT) is(More)
The unique capabilities of EPR spin trapping of nitric oxide based on a ferrous-dithiocarbamate spin trap have been demonstrated in a study verifying the source of the nitrogen and oxygen atoms in nitric oxide produced from activated macrophages. Spin trapping experiments were performed during nitric oxide generation from activated mouse peritoneal(More)
The catalytic activity and molecular aspects of Thiobacillus novellus cytpchrome c oxidase were affected by ATP. The steady-state kinetics in the oxidation of ferrocytochrome c by the oxidase varied with the presence or absence of ATP; the [S]-v curve of the reaction was sigmoid in the absence of ATP whereas it was a Michaelis-Menten-type hyperbola in the(More)
