Juvenile polyps are present in a number of Mendelian disorders, sometimes association only with gastrointestinal cancer [juvenile polyposis syndrome (JPS)] and as part known syndromes (Cowden, Gorlin Banayan-Zonana) developmental abnormalities, dysmorphic features or extra-intestinal tumours. Recently, gene for JPS was mapped to 18q21.1 the candidate DPC4 (SMAD4) shown carry frameshift mutations some families. We have analysed eight families linkage DPC4. Overall, there no evidence DPC4;...

This paper reports for the first time presence in anaerobic rumen ciliate Dasytricha ruminantium (Schuberg) of microbody-like organelles, about 0.5 micrometer diameter, with a granular matrix and an equilibrium density approx. 1.18 g/ml. These organelles can be isolated fraction sedimented at 10(5) g-min that contains 67% total pyruvate synthase (EC 1.2.7.1), 66% hydrogenase 1.18.3.1) 20% lactate dehydrogenase 1.1.1.27). Thus several respects this is enzymically similar to those containing...
