The blood supplies of nodular lesions associated with liver cirrhosis were analyzed in vivo various imaging modalities. portal supply was evaluated computed tomography (CT) during arterial portography (CTAP); the hepatic angiography, CT following intraarterial injection iodized oil, or ultrasound carbon dioxide microbubbles. A total 84 surgically confirmed hepatocellular carcinomas (HCCs) (less than equal to 3 cm) and 25 areas adenomatous hyperplasia (AH) included study. At CTAP, a seen 96%...

To assess the hemodynamics and main drainage vessel of hypervascular hepatocellular carcinoma.Single-level dynamic computed tomography during hepatic arteriography (CTHA) was performed in 32 patients with carcinoma. Carcinoma confirmed histologic (n = 9) or clinical 23) examination results. Single-level CTHA findings were retrospectively analyzed. Histologic specimens from 40 livers carcinoma also examined, special attention to vessels along rim lesion.Contrast material enhancement on...

Differentiation of hepatocellular carcinomas from adenomatous hyperplastic nodules (AHNs) is important for the early and precise detection carcinoma in cirrhotic liver. For this purpose, authors compared findings on magnetic resonance (MR) images surgically resected AHNs (n = 7) with those 47). were divided into two histologic groups: without atypia 5) atypical hepatocytes or malignant foci 2). All hyperintense T1-weighted spin-echo hypointense T2-weighted relative to surrounding However,...

To analyze the correlation between pseudolesions seen in segment IV of liver and aberrant gastric venous drainage (AGVD).Twenty-two patients with a pseudolesion posterior edge (group A) 100 randomly selected without B) underwent computed tomography during arterial portography (CTAP) hepatic arteriography. The frequency visualization AGVD to was compared for groups A B.AGVD at arteriography 18 22 group A. None B had AGVD. difference angiographically visible statistically significant (chi 2...

PURPOSE: To compare the efficacy of fat-suppressed T1-weighted magnetic resonance (MR) imaging and dynamic MR in diagnosis small pancreatic adenocarcinomas. MATERIALS AND METHODS: Pancreatic adenocarcinomas 15 patients were evaluated with computed tomography (CT) five sequences that included technique multiplanar gradient-recalled acquisition steady state technique. RESULTS: The difference contrast-to-noise ratios between tumor normal pancreas was significantly different (P < .05) used. In...

One of the most common sites focal sparing in fatty livers (focal spared area) shown by sonography or CT is posterior edge segment IV. The differentiation such a area from tumor has been diagnostic challenge. purpose this study was to determine if correlation exists between at IV liver and decrease portal perfusion main vein due aberrant gastric venous drainage directed into IV.Seventeen patients with diagnosed on basis sonographic findings who had hepatic arteriography and/or during...

We report a histological analysis of the areas high density in postequilibrium and delayed phase CT 43 focal hepatic lesions. The cases consisted 16 cholangiocellular carcinomas, 9 hepatocellular carcinomas (including sclerosing type carcinoma combined hepatocellular-cholangiocellular carcinoma), 13 metastases, 2 granulomas, an inflammatory pseudotumor, malignant lymphoma, epithelioid hemangioendothelioma. Computed tomography was performed after angiography using 40–50 g iodine...

A matured megakaryocyte releases thousands of platelets through a drastic morphological change, proplatelet formation (PPF). The megakaryocyte/erythrocyte-specific transcription factor, p45 NF-E2, is essential for initiating PPF, but the factor regulating PPF has not been identified. Here we report that estradiol synthesized in megakaryocytes triggers PPF. We demonstrate key enzyme steroid hormone biosynthesis, 3beta-hydroxysteroid dehydrogenase (3beta-HSD), target and rescues...

Focal fatty change of the liver adjacent to falciform ligament: CT and sonographic findings in five surgically confirmed casesJ Yoshikawa, O Matsui, T Takashima, H Sugiura, K Katayama, Y Nishida M TsujiAudio Available | Share

Measurement of the pituitary height was performed on magnetic resonance (MR) images 213 subjects with no known or suspected and/or hypothalamic disorders. Midsagittal, T1-weighted were used for measurements and mean heights in each age sex group obtained. In 10 to 69 year range, greater females than males. The groups 0–9 years both genders showed minimum maximum themean observed 19 genders. gradually decreased increasing after 20 years. There a ≥9.0 mm ≥8.0 marked discrepancy between MR...

Ciliated hepatic foregut cysts (CHFCs) are solitary unilocular in the liver that histologically similar to bronchogenic cysts. Three cases of CHFC reported demonstrated radiologic features those solid masses. All lesions were smaller than 3 cm diameter and subcapsular. At ultrasonography, one lesion appeared anechoic but other two hypoechoic. Unenhanced computed tomography be hyperattenuating or isoattenuating relative surrounding parenchyma, no enhanced with administration contrast...

The frequency and degree of intrahepatic periportal abnormal intensity (PAI) on magnetic resonance images in patients with or without various hepatobiliary pancreatic diseases were analyzed. In 63 disease, except for a small metastatic liver tumor cavernous hemangioma, no definite PAI was seen. Definite seen all obstructive jaundice, cholangitis, cholangiocellular carcinoma. It also clearly four cases malignant lymphadenopathy the hepatoduodenal ligament, one two acute hepatitis, 47...

At least five types of beta-fructofuranosidases (FFases I, II, III, IV and V) were found in the cell wall Aureobasidium pullulans DSM2404 grown a sucrose medium. The fungus first catalyzed transfructosylation sucrose, produced fructooligosaccharide (FOS) glucose culture. FOS was then consumed together with glucose, finally fructose produced. In FOS-producing period, expressed FFase I as dominant FFase. However, FOS-degrading levels FFases V increased. ratios transfructosylating activity to...

Alphaproteobacterium strain Q-1 is able to oxidize iodide (I(-)) molecular iodine (I(2)) by an oxidase-like enzyme. One of the two isoforms iodide-oxidizing enzyme (IOE-II) produced this was excised from a native polyacrylamide gel, eluted, and purified. IOE-II appeared as single band (51 kDa) showed significant in-gel activity in sodium dodecyl sulfate-polyacrylamide gel electrophoresis without heat treatment. However, at least bands with much higher masses (150 230 were observed treatment...
