This review is dedicated to electric field effects on giant unilamellar vesicles, a cell-size membrane system. We summarize various types of behavior observed when vesicles are subjected either to weak AC fields at various frequency, or to strong DC pulses. Different processes such as electrodeformation, -poration and -fusion of giant vesicles are considered. We describe some recent development...

The 'tongue-and-groove problem' in step-and-shoot delivery of intensity modulated radiotherapy is investigated. A 'tongue-and-groove' index (TGI) is introduced to quantify the 'tongue-and-groove' effect in step-and-shoot delivery. Four different types of leaf sequencing methods are compared. The sliding window method and the reducing level method use the same number of field segments to deliver...

Toxic epidermal necrolysis (TEN) is a server, life-threatening drug-induced mucocutaneous eruption that rarely affects scalp. There has been limited number of cases of TEN arising in patients receiving radiation therapy plus anticonvulsants.Here, we report a case of TEN secondary to anticonvulsant and radiation therapy. An unusual aspect shared by our patient as well as the other reported cases...
