background and objective: nanoscopic life forms called nanobacteria or calcifying nanoparticles (cnp) are unconventional agents. these novel organisms are very small (0.1 to 0.5 microns) and possess unusual properties such as high resistance to heat and routine antimicrobial agents. nanobacteria are 100 times smaller than bacteria and protected by a shell of apatite, so they could be as candida...

Previous studies have suggested a relationship between bile duct stones and periampullary duodenal diverticula. The aim of the present study was to examine this association in more detail, including step-wise logistic regression to identify independent predictors for the presence of diverticula. Clinical, endoscopic and radiological data were analysed from 794 consecutive subjects with bile duc...
