INTRODUCTION Several factors are used to stratify the probability of polyp recurrence. However, there are no studies correlating the location of the initial polyps and the recurrent ones. The aim of this study was to verify whether the polyp location at the surveillance colonoscopy was correlated with the location of the previously excised polyps at the baseline colonoscopy. METHODS A retrosp...

Inorganic polyphosphate (polyP) is a linear polymer of tens or hundreds of phosphate residues linked by high-energy bonds. It is found in all organisms and has been proposed to serve as an energy source in a pre-ATP world. This ubiquitous and abundant biopolymer plays numerous and vital roles in metabolism and regulation in prokaryotes and eukaryotes, but the underlying molecular mechanisms for...

Eustachian tube maintains middle ear pressure equal to that of atmospheric pressure and its functions is deranged due to various nasal, nasopharyngeal and palatal causes. Nasal polypi cause post nasal drip which is considered to cause Eustachian tube dysfunction. The present cross sectional study comprises of a total of 39 patients of Antrochoanal polyp with the aim to see the effect of antroch...

Virtual colonoscopy (VC) allows a user to virtually navigate within a reconstructed 3D colon model searching for colorectal polyps. Though VC is widely recognized as a highly sensitive and specific test for identifying polyps, one limitation is the reading time, which can take on average 30 minutes per patient. Large amounts of the colon are often devoid of polyps, and a way of identifying thes...

Volumetric laser endomicroscopy (VLE) is a recent advanced imaging technology that allows high resolution microstructure imaging of the esophagus and gastric cardia; it has been increasingly used in Europe and the USA [1–3]. The system has been recently upgraded to include a laser marking device that places cautery marks on the mucosa to provide targets for histology. We report a case of an inc...

Arbuscular mycorrhizal (AM) fungi form symbiotic associations with land plants and supply soil minerals including phosphorus to their hosts. AM accumulate polyphosphate (polyP), a linear phosphate polymer, in mycelia, which functions storage translocation. In the budding yeast Saccharomyces cerevisiae, it has been demonstrated that vacuolar transporter chaperone 4 (VTC4) protein, subunit of VTC...

A case of solitary gastric hamartomatous polyp, presenting as upper gastrointestinal haemorrhage, is reported. Both the entity itself, and the clinical presentation, are exceptional. The significance of the solitary gastric hamartomatous polyp and implications of its diagnosis are discussed.
