Use of a non-endoscopic immunocytological device (Cytosponge™) for post chemoradiotherapy surveillance in patients with oesophageal cancer in the UK (CYTOFLOC): A multicentre feasibility study.

Background: Effective surveillance strategies are required for patients diagnosed with oesophageal squamous cell carcinoma (OSCC) or adenocarcinoma (OAC) for whom chemoradiotherapy (CRT) is used as a potentially-curative, organ-sparing, alternative to surgery. In this study, we evaluated the safety, acceptability and tolerability of a non-endoscopic immunocytological device (the Cytosponge™) to assess treatment response following CRT.

Methods: This multicentre, single-arm feasibility trial took place in 10 tertiary cancer centres in the UK.

Production and binding analyses of a humanised scFv against a cryptic epitope on tumour-associated fibronectin.

Tumour-associated splice variants of fibronectin are a major source of tumour-matrix associated targets and are proving very successful in the development of clinical agents to treat cancer. One of the first monoclonal antibodies to be produced to this target, murine BC-1, recognises a cryptic epitope in domain 7 of the B-form splice variant (EDB-FN). Antibody fragments based on this immunoglobulin (IgG) were unstable, but BC-1 humanisation provided an opportunity to produce a more stable single-chain Fv (scFv).

A UK clinical isolate of Bordetella hinzii from a patient with myelodysplastic syndrome.

What is believed to be the first clinical isolate of Bordetella hinzii in the UK, from a patient with myelodysplastic syndrome, is described. This patient had no known avian exposure, and the source of the organism remains unknown. It appears that the underlying immune deficiency of the patient increased the susceptibility to opportunistic infection with this organism.

Molecular determinants of the cell-cycle regulated Mcm1p-Fkh2p transcription factor complex.

The MADS-box transcription factor Mcm1p and forkhead (FKH) transcription factor Fkh2p act in a DNA-bound complex to regulate cell-cycle dependent expression of the CLB2 cluster in Saccharomyces cerevisiae. Binding of Fkh2p requires prior binding by Mcm1p. Here we have investigated the molecular determinants governing the formation of the Mcm1p- Fkh2p complex.
