Follicular lymphoma grade 3B and diffuse large B-cell lymphoma present a histopathological and molecular continuum lacking features of progression/ transformation.

The sole distinguishing feature of follicular lymphoma grade 3B and diffuse large B-cell lymphoma is the growth pattern assessed by histopathology. Diffuse growth defines diffuse large B-cell lymphoma but the clinical relevance of this finding when occurring in follicular lymphoma grade 3B is uncertain. To address this issue, individual and coexisting follicular lymphoma grade 3B and diffuse large B-cell lymphoma were separated and analyzed for immunophenotype and molecular genetic features by fluorescence in situ hybridization, targeted sequencing and gene expression profiling.

Impact of different storage factors on the survivability of Campylobacter jejuni in turkey meat.

Campylobacter jejuni is often prevalent in turkey and poultry, but the effects of storage temperatures and storage periods and the interruption of the cooling chain on its survival have not been evaluated so far. In this study, 700 samples of turkey meat were artificially contaminated by inoculating their surface with 10(3) CFU of C. jejuni per sample, wrapped in airtight cellophane bags, and stored under different chilling and freezing conditions for various storage periods; this was followed by analysis of the cultures.
