AIM: To investigate the outcome of repeating endoscopic retrograde cholangiopancreaticography (ERCP) after initially failed precut sphincterotomy to achieve biliary cannulation.

Free zinc is also associated with the neuronal retina but at lower amounts where it is thought to participate in a number of functions, including being a neuromodulator. In the studies conducted we now provide experimental evidence to show that zinc is a key mediator and modulator of neuronal death in the retina. For example, physio-展开更多
