Primary transpupillary thermotherapy for choroidal melanoma in 391 cases: importance of risk factors in tumor control.

Purpose: To report the long-term outcome of primary transpupillary thermotherapy (TTT) for choroidal melanoma.

Design: Retrospective review of medical records.

Participants: We included 391 patients with choroidal melanoma treated between 1995 and 2012 at the Oncology Service, Wills Eye Hospital, Philadelphia.

Chemical behavior of electrochemically generated nanostructured silver surfaces.

A simple electrochemical method has been proposed for the preparation of silver nanoparticles that can be used for the detection of cyanide. Both the electrochemical behavior and morphology of the Ag nanoparticles have been characterized in the presence of KCN or diethyl cyanophosphonate (DECP) as well as in alkaline media. These were investigated by cyclic voltammetry and scanning electron microscopy (SEM).
