摘要:
A multi-layer ceramic substrate is formed of a plurality of glass-ceramic layers. The glass-ceramic layers (partly not shown) contain amorphous glass and alumina (Al2O3), and interconnection patterns of silver are formed in the surfaces of the glass-ceramic layers. The amorphous glass is anorthite (CaAl2Si2O8), for example. With the multi-layer ceramic substrate, the upper limit of the firing temperature is set so that the degree of crystallinity is 12% or less. The lower limit of the firing temperature is set so that the multi-layer ceramic substrate has a sintered density of 95% or more with respect to the sintered density that the multi-layer ceramic substrate exhibits when the degree of crystallinity is 25%.

摘要:
Conventional oligonucleotides are opened at both ends and thereby unstable. The stability of them against catabolic enzymes is increased by phosphorothioate modification, but such phosphorothioate causes toxicity. The present invention provides oligonucleotides and medicaments in which these problems are improved. That is, it provides a staple oligonucleotides and medicaments containing the same as the active ingredient. Specifically, it provides transcription factor inhibitors, antisense oligonucleotides and siRNAs. More specifically, it provides agents for preventing, treating or improving inflammation, autoimmune diseases, central diseases, reperfusion injury in ischaemic diseases, worsened prognosis after organ transplantation or organ surgery, or restenosis after PTCA. Further specifically, it provides agents for preventing, treating or improving arthritis, dermatitis, nephritis, hepatitis, renal failure, cystitis, prostatitis, urethritis, ulcerative colitis, Crohn disease, chronic rheumatoid arthritis, osteoarthritis, atopic dermatitis, contact dermatitis, psoriasis, cutaneous ulcer or decubitus.

A composite magnetic material contains first magnetic particles made of a first magnetic material and second magnetic particles made of a second magnetic material, the first and second magnetic particles being mixed with each other. A frequency characteristic of the first magnetic material is different from that of the second magnetic material. The first and second magnetic particles are mixed so that, at a frequency of an intersecting point between a first curve representing a frequency characteristic of a real part of a complex magnetic permeability of the first magnetic material and a second curve representing a frequency characteristic of a real part of a complex magnetic permeability of the second magnetic material, a value of a real part of a complex magnetic permeability of the composite magnetic material is larger than a value of the intersecting point.

An ultrasonic diagnostic apparatus is provided for displaying a color map on which a difference in blood flow dynamics is reflected. Setting a test subject who is administered a contrast agent is assumed as an imaging target, and a probe transmits and receives ultrasonic waves to and from the target for contrast imaging. Image data is constructed based on signals received by the probe and a time-intensity curve is generated from intensity values of the image data. According to the time-intensity curve, a value of a predetermined parameter is calculated for producing a distribution image of blood flow dynamics. The distribution image (color map) of the blood flow dynamics is produced from the parameter value. The color map is a two-dimensional or a three-dimensional image being color-coded according to the parameter value. At least one of the followings may be used as the parameter; a contrast agent inflow start time, a balanced intensity arrival time, a contrast agent disappearance start time, a contrast agent duration, a preset threshold arrival time, an intensity increase rate, an intensity decrease rate, intensity of balanced state, and a total flow amount.

In a medical digital X-ray imaging apparatus having a plurality of imaging modes including computed tomography mode, a supporter supports an X-ray source and a digital X-ray sensor having a two-dimensional detection plane for detecting X-rays, while interposing an object between them. An image reconstructor acquires data from the digital X-ray sensor and reconstructs an image based on the acquired data. An operator selects one of a first imaging mode and a second imaging mode. The second imaging mode has an irradiation field different from the first imaging mode and has an area to be read in the digital X-ray sensor smaller than that in the first imaging mode.

摘要:
An edge between a tumor and a normal tissue is detected even when acoustic impedance and elasticity of those are not changed. An edge position of tissue is estimated by setting a plurality of estimation regions of an inspection object, detecting direction of motion of the inspection object within each estimation region, and computing the point of inflexion in the direction of motion. Moreover, these edge positions are overlapped on the cross-sectional images and thereby an operator can easily detect the edge lines.
