Glucagon-like peptide-1 (GLP-1) analog liraglutide inhibits endothelial cell inflammation through a calcium and AMPK dependent mechanism.

Liraglutide is a glucagon-like peptide-1 (GLP-1) mimetic used for the treatment of Type 2 diabetes. Similar to the actions of endogenous GLP-1, liraglutide potentiates the post-prandial release of insulin, inhibits glucagon release and increases satiety. Recent epidemiological studies and clinical trials have suggested that treatment with GLP-1 mimetics may also diminish the risk of cardiovascular disease in diabetic patients.

Endoscopic ablation of dysplastic Barrett's oesophagus comparing argon plasma coagulation and photodynamic therapy: a randomized prospective trial assessing efficacy and cost-effectiveness.

Objective: Endoscopic mucosal ablation is a promising technique that is used to treat dysplastic Barrett's oesophagus. The purpose of this study was to investigate the efficacy and cost-effectiveness of two promising techniques, argon plasma coagulation (APC) and photodynamic therapy (PDT), in the ablation of dysplastic Barrett's oesophagus.

Materials And Methods: Twenty-six patients with dysplastic Barrett's oesophagus (21 M, median age 60 years, median length 4 cm, 23 low-grade dysplasia (LGD), 3 high-grade dysplasia (HGD)) were randomized to APC: 13 patients, PDT: 13 patients.

A randomized, prospective cross-over trial comparing methylene blue-directed biopsy and conventional random biopsy for detecting intestinal metaplasia and dysplasia in Barrett's esophagus.

Background And Study Aims: The value of methylene blue-directed biopsies (MBDB) in detecting specialized intestinal metaplasia and dysplasia in Barrett's esophagus remains unclear. The aim of this study was to compare the accuracy of MBDB with random biopsy in detecting intestinal metaplasia and dysplasia in patients with Barrett's esophagus.

Patients And Methods: A prospective, randomized, cross-over trial was undertaken to compare MBDB with random biopsy in patients with Barrett's esophagus segments 3 cm or more in length without macroscopic evidence of dysplasia or cancer.

Photodynamic therapy (PDT) for oesophageal dysplasia and early carcinoma with mTHPC (m-tetrahydroxyphenyl chlorin): a preliminary study.

Barrett's oesophagus is a premalignant condition in which stratified squamous type mucosa of the normal oesophagus is replaced by specialised intestinal type columnar mucosa. Oesophageal resection was previously considered to be the treatment of choice for high-grade dysplasia or superficial carcinoma arising in this columnar-lined mucosa. We treated four patients with Barrett's oesophagus and high-grade dysplasia, and one patient with superficial oesophageal carcinoma with photodynamic therapy (PDT) using an argon-pumped dye laser light (652 nm).
