Abstract
We have found that multidendritic nociceptors in the head respond to harsh touch throughout their receptive field but respond to gentle touch only at the tip of the nose. Whereas the harsh touch response depends solely on cell-autonomous mechanosensory channels, gentle nose touch responses require f...

Abstract
We also exploit techniques from robust statistics to make the methods resistant to large local decorrelations. We further introduce Kalman filtering for calculating the strain field from the displacement field given by the AM methods. Simulation and phantom experiments show that both methods generat...

Abstract
SD-OCT revealed a convex dome-shaped cavity lined by a hyperreflective layer in all cases, which persisted until the end of follow-up. Two patients complained of metamorphopsia, although BCVA improved dramatically in all cases. The site of laser puncture was visible in 2 patients. No abnormality was...

Abstract
Extrusion of an implant after medialization laryngoplasty is unusual and warrants removal. Most commonly, it extrudes through the laryngeal introitus, but rarely, it extrudes through the pyriform sinus.

232 patients were included. The mean (range) age was 50 (18-83) years. 63% were women. The mean (range) energy delivery was 89.8 (44.5-158.4) J/cm. There was no significant effect on any outcome related to increasing energy delivery. CONCLUSION: Up to 160 J/cm, increasing energy delivery has no sign...

Abstract
Bonds formed by linear heating were stronger than the ones formed by step heating: at T(set) = 80 degrees C the bonds were 40% stronger and at T(set) = 90 degrees C the bonds strength was nearly doubled. The bond strength difference between the heating methods was larger as T(set) increased. CONCLUS...

Since 2001 the femtosecond laser has primarily been used in refractive surgery, e. g., for lasik, implantation of intracorneal ring segments or antiastigmatic corneal incisions. However, the femtosecond laser is more and more used for therapeutic reasons in corneal surgery. In this context it is use...
