PURPOSE To determine serial changes in hepatocellular carcinomas (HCCs) treated with percutaneous radio-frequency (RF) ablation at long-term follow-up multiphase helical computed tomography (CT). MATERIALS AND METHODS There were 43 nodular HCCs in 40 patients at follow-up CT performed not less than 12 months after RF ablation. All patients underwent(More)
OBJECTIVE We conducted this study to compare tumor measurement by computed tomography (CT) and tumor response assessment between Response Evaluation Criteria In Solid Tumors (RECIST) 1.0 and RECIST 1.1 in patients with metastatic colorectal cancer (CRC). METHODS We reviewed the medical records of patients with metastatic CRC who received first-line(More)
PURPOSE To determine characteristic features of peripheral cholangiocarcinoma on two-phase spiral computed tomographic (CT) scans. MATERIALS AND METHODS Thirty-four patients with peripheral cholangiocarcinoma underwent two-phase spiral CT. Hepatic arterial phase and portal venous phase images were obtained 30 and 65 seconds, respectively, after the start(More)
Characterization of many osmotic stress-induced genes has greatly contributed to the understanding of the physiological responses of plant cells to osmotic stress at the molecular level. In this study we constructed a subtraction library and generated 15 salt stress-inducible ESTs from this library to use as molecular markers that reflect the cellular(More)
PURPOSE To evaluate the usefulness of power Doppler ultrasonography (US) with a microbubble contrast agent in assessing the therapeutic response of hepatocellular carcinomas (HCCs) treated with percutaneous radio-frequency (RF) ablation. MATERIALS AND METHODS Forty patients with 45 nodular HCC lesions 1.0-3.8 cm in diameter underwent power Doppler US(More)
A prospective study was performed to evaluate whether pulse inversion harmonic imaging and tissue harmonic imaging improve the lesion conspicuity and change ultrasonographic characteristics of focal hepatic lesions. Three radiologists evaluated 97 focal hepatic lesions by consensus: cirrhosis-related nodules (n = 23), metastases (n = 23), hemangiomas (n =(More)
Dynamin, a GTP-binding protein, is involved in endocytosis in animal cells. We found that a dynamin-like protein, ADL1, is present in multiple forms in Arabidopsis leaf tissue. Subcellular fractionation experiments, together with gel-filtration and nondenaturing-gel electrophoresis revealed that most of ADL1 is present as a high-molecular-mass complex of(More)
In some patients, eosinophilic gastroenteritis(EG) occurs in those with food allergy. We experienced a non-atopic asthmatic who had an EG associated with food allergy to fish and eggs, and blood eosinophilia. A skin prick test and RAST to causative food allergens showed a negative result. A fiber-optic endoscopic biopsy from the gastric mucosa showed an(More)
PURPOSE To determine whether the combination of CT during arterial portography (CTAP) and CT hepatic arteriography (CTHA) provides an added benefit to triple-phase helical CT (THCT) alone in the preoperative evaluation of hepatocellular carcinoma (HCC). MATERIALS AND METHODS Fifty-two consecutive patients with pathologically proved HCC underwent THCT(More)
PURPOSE To assess an early thin-section computed tomographic (CT) finding of the localized formation of bronchioloalveolar carcinoma (BAC). MATERIALS AND METHODS From October 1994 to September 1995, four consecutive patients with biopsy-proved BAC were studied. Thin-section CT (n=4), radiographic (n=4), pathologic (n=4), and positron emission tomographic(More)
