Rare case of small intestine bleeding.

We present a case of a healthy 59-year-old woman who presented for a capsule endoscopy to evaluate melaena and iron deficiency anaemia. She had previously underwent an oesophagogastroduodenoscopy and colonoscopy at an outside institution which were unremarkable. Capsule endoscopy showed an ulcerated, bleeding lesion likely in the duodenum.

AFPep: an anti-breast cancer peptide that is orally active.

Background: We have synthesized a cyclic nonapeptide (AFPep) that is effective, after being administered by parenteral routes, for the treatment or the prevention of breast cancer. To test the hypothesis that AFPep remains safe and efficacious after oral administration, three different whole-animal bioassays were utilized, and the mechanism by which AFPep functions was investigated.

Methods: Using a human breast cancer xenograft model in mice for therapeutic activity, a carcinogen-induced breast cancer model in rats for prevention efficacy, and a mouse uterus growth inhibition model of anti-estrogenic activity, AFPep was administered by oral gavage (p.
