Cigarette smoking is the most crucial factor responsible for chronic obstructive pulmonary disease (COPD). The precise mechanisms of the development of the disease have, however, not been fully understood. Recently, impairment of pulmonary endothelial cells has been increasingly recognized as a critical pathophysiological process in COPD. To verify this(More)
We have developed a very sensitive high-frequency carrier-type magnetic field sensor based on the giant magneto-impedance effect available at lower frequencies. Our approach is to optimize the sensor structure so as to obtain high impedance. In addition, we optimize the carrier suppressing circuit using a low-noise crystal oscillator to reduce the phase(More)
The purpose of this study was to establish the technique of multiplanar reconstruction (MPR) with multidetector-row (MDR) computed tomography (CT) guided needle biopsy for the diagnosis to access very difficult lesions. The CT guided percutaneous biopsy are well-established methods to obtain cytological and histological material such as the peripheral(More)
A 62-year-old man was referred to our hospital because of persistent sub-fever. A pulmonary fungal infection was suspected owing to the elevation of the serum-D-glucan level. Since a chest radiograph and a CT scan revealed intrabullous fluid in the right upper lobe, percutaneous needle aspiration was performed. Although acid-fast bacilli smears of the(More)
