Our findings of a general decrease in proliferative activity of thyroid cells with age may explain, at least in part, the higher risks of radiation-related thyroid cancer in children compared with adults. However, the variation in the rate of cell proliferation is unlikely to be responsible entirely for this phenomenon and other factors may also be involved.

These results suggest that markers of tumor angiogenesis may predict survival in patients with peritoneal surface metastases from mucinous adenocarcinoma. These findings provoke the hypothesis that antiangiogenic therapies may be effective in patients with this devastating disease.

Fish bones are one of the most common foreign bodies in the upper aero-digestive tract. The use of plain X-ray in identifying fish bones has questionable value. We believe that the knowledge of the type of the fish ingested improves the diagnostic value of the neck X-rays. This study was designed to evaluate the relative radio-densities of the bones of commonly eaten fish in the UK. Twenty-three species of fish were studied and their bones were grouped into three depending upon their ratio-densities. This information is expected to be useful in identifying fish bones while reading plain radiography.
