Bottom Line: Metastases developed from the squamous carcinomas exclusively.Desmosomes and gap junctions were detected in basal cell carcinomas whereas, in squamous carcinomas, tight junctions were also seen.While all three types of junction were found in the primary squamous...

Bottom Line: Computed tomographic scanning of the chest in 100 patients with newly diagnosed malignant lymphoma detected mediastinal lymphadenopathy (39%) and parenchymal deposits (15%) with a significantly greater sensitivity and specificity than conventional radiological...

Bottom Line: Plasminogen activator and tumour angiogenesis factor were the malignancy-associated markers.The normal adult brain-derived lines showed some differentiated astroglial features and expressed low levels of the malignancy-associated properties.Plasminogen activator...

Bottom Line: But even at 25 days normal crypt structures were still evident.They were no longer seen in explants examined after this time however and, indeed, there appeared to be no difference in the morphology and survival of control and DMH-treated mucosae.It is possible...

Bottom Line: Four sublines CMT167, 170, 175 and 181 with increased metastatic ability were selected, as described in the accompanying paper (Layton & Franks, 1984).No ultrastructural differences were found that might correlate with metastatic behaviour in vivo.Metastases,...

Bottom Line: Standard (UICC) crocidolite was subjected to ball milling to reduce the length of the fibre.Previous in vitro work on the same materials had suggested that biological activity was related to fibres greater than 6.5 microns in length and that the material milled...
