Abstract: A method is disclosed of treating pain with senicapoc, a potent Ca2+-activated K+ channel, KCa3.1 antagonist in CNS-resident microglia. Senicapoc is shown to cause in a decrease of IL-1? and NO release from microglia cells vivo and in vitro. Because of contribution of KCa3.1 to neuropathological processes, senicapoc is useful in the treatment of chronic, neuropathic, visceral, and inflammatory pain and the reversal of tactile allodynia.

Abstract: A portable control apparatus (100) for controlling a motion sensor (200), comprising communication means (110), display means (120) and input means (130). The communication means (110) allow wireless communication with a motion sensor (200) and are suitable for receiving a detection signal, currently generated in the motion sensor (200), from the motion sensor (200) while the control apparatus (100) is in a detection region (210) of the motion sensor (200). The display means (120) allow this detection signal to be displayed. The input means (130) allow the adjustment of a detection threshold at which a movement is detected by the motion sensor (200), on the basis of the displayed detection signal. The adjusted detection threshold is transferred to the motion sensor (200) by the communication means (110) and set there as the applicable detection threshold.

Abstract: Neuroinflammation mediated by microglia and infiltrating peripheral immune cells is a major component of stroke pathophysiology. The calcium activated potassium channel KCa3.1 is expressed selectively in the injured CNS by microglia, and KCa3.1 function has been implicated in proinflammatory activation of microglia. KCa3.1 is further implicated in the pathophysiology of ischemia/reperfusion (stroke) related brain injury. Senicapoc, an investigational drug with a proven safety profile and shown to cross the blood-brain barrier, is a potent and selective KCa3.1 inhibitor that intervenes in the inflammation cascade that follows ischemia/reperfusion, and is a potential treatment for stroke.
