One case showed perineural invasion by otherwise deceptively benign-appearing microcystic structures, one had areas transitioning to intraductal tubulopapillary neoplasm, and 3 cases harbored more conventional small-duct CCA foci. In those 3 cases, both the tubulocystic and conventional CCA components ...
Identifying and documenting the suspect foci (granular, irregular areas within or on the cyst wall) are essential to rule out papillary nodules or carcinomas. Also, subclassification of IPMNs into branch or main duct types relies heavily on macro- scopic examination and guided sampling. Along the...
The degree of dysplasia exhibited by the epithelium may range from mild to moderate to severe (carcinoma in situ), and the foci of early malignancy may be evident by the presence of mural nodules.17 The solid malignancies that arise from IPMN are more likely to have papillary features, as ...
In endemic areas, the annual incidence of CE ranges from <1 to 200 per 100,000 inhabitants (WHO/OIE, 2001); that of AE ranges from 0.03 to 1.2 per 100,000 inhabitants (Schweiger et al., 2007) but may be significantly higher in certain endemic foci (WHO/OIE, 2001, Craig, 2003). ...
The transformed cells can then be selected by foci formation. A similar vector, in which the gene for neomycin resistance (Southern and Berg, J. Mol, Appl. Gen 1 , 327 (1982)) has been inserted into the same unique Sal I site, may advantageously also be super-transfected into the same...

68 Ga-PSMA PET/CT (A–E) revealed a PSMA-avid tumor in the right maxillary sinus (green arrow, SUVmax 11.2), multiple bone metastases (red arrow, SUVmax 16.2), and liver metastases (blue arrow, SUVmax 8.8). 18F-FDG PET/CT (F–J) showed negative recurrent and metastatic foci Full ...
Histopathological examination suggested a diagnosis of two foci of biliary dysplasia: cystic duct and lower common bile duct. Fifteen months later, the patient re-presented with signs of obstructive jaundice and biliary sepsis. Although CT scan revealed images highly indicative of metastatic disease, ...
Vorinostat alone did not cause significant accumulation of γ-H2AX foci in any of the ACC cells (Fig. 5A, ns p > 0.05). Combined therapy also induced the accumulation of γ-H2AX foci in both ACC cell lines (Fig. 5A, ***p < 0.001). Using another marker of senescence, we observed a...
