Benign pathologies demonstrated after a Whipple's resection (pancreatoduodenectomy) for pancreatic and peri-ampullary lesions are relatively uncommon. Here we report two cases where a Whipple's procedure was undertaken for suspected pancreaticobiliary cancer and where the final histology revealed, in each case, a rare benign lesion. The first case confirmed a cholesterol polyp in the distal com...

Distal colonic K(+) excretion is determined by the balance of K(+) absorption and K(+) secretion of the enterocytes. K(+) secretion occurs via active basolateral K(+) uptake mostly via the NKCC1 co-transporter followed by K(+) exit via a luminal K(+) channel. The specific focus here is directed towards the luminal secretory K(+) channel (1). Several recent observations highlight the pivotal rol...

Planar polarity development in the Drosophila wing is under the control of the frizzled (fz) pathway. Recent work has established that the planar polarity (PP) proteins become localized to either the distal, proximal, or both sides of wing cells. Fz and Dsh distal accumulation is thought to locally activate the cytoskeleton to form a hair . Planar polarity effector (PPE) genes such as inturned ...
