Unfavourable prognosis associated with K-ras gene mutation in pancreatic cancer surgical margins.

abstract：OBJECTIVE:The number of colonoscopies required to reach competency is not well established. The primary aim of this study was to determine the number of colonoscopies trainees need to perform to attain competency, defined by a caecal intubation rate (CIR) ≥90%. As competency depends on completion, we also investigated ...

abstract：:Studies in the rat jejunum in vivo have shown that 5-hydroxytryptamine (5-HT) causes secretion of fluid and luminal release of prostaglandin (PG) E2. These effects can be blocked by indomethacin and ketanserin, which suggests that PGE2 may be an important intermediate in the transduction mechanism leading to 5-HT indu...
