Methods We retrospectively reviewed 439 consecutive cases sent to a single dermatopathology lab from a practitioner’s general dermatology office who also performs Mohs micrographic surgery. One hundred cases had a histopathologically proven carcinoma LY333531 on biopsy with subsequent
excision. Histopathologic type, location, age, sex, and time from biopsy to excision were all analyzed for statistical association. Results Of 57 cases of basal cell carcinoma, 34 (59.6%) had positive residuals. Of 43 cases of squamous cell carcinoma, 12 (27.9%) had positive residuals. Histologic type was significantly associated (p=.002) with residual carcinoma in excisional specimens, with basal cells 2.13 times as likely to have residual carcinoma present. Conclusion The rate of residual nonmelanoma carcinoma in excision specimens after shave biopsy was found to be different from previously reported in the literature. These data may have therapeutic ramifications if further substantiated.”
“We have investigated the transport properties and electronic states of W-doped anatase TiO2 (Ti1-xWxO2) fabricated by pulsed-laser deposition. Based
on transport and photoemission spectroscopy GSK1838705A (PES) measurements, we discuss the conduction mechanism of Ti1-xWxO2, focusing on the valence state of W. The Ti0.95W0.05O2 film deposited under optimized conditions showed a resistivity of 2×10(-3) cm at room temperature, which is approximately ten times higher than that of Ti0.94Nb0.06O2. This is mainly due to the lower carrier density in Ti1-xWxO2 films. From PES measurements of Ti0.91W0.09O2 films, we observed the finite density of states originating from O 2p hybridized with W near the top of the valence band. However, we could not find any states at the same position in the Ti0.94Nb0.06O2 films. In addition, the density of
states selleck compound near the Fermi level [N(E-F)] was found to be quite low in the Ti0.91W0.09O2 films. Indeed, this is in sharp contrast to Ti0.94Nb0.06O2, which indicates a remarkably high N(E-F) value assigned to the bottom of the Ti 3d conduction band. The difference in transport properties between Ti1-xWxO2 and Ti1-xNbxO2 can be attributed to the existence of impurity states that trap carriers associated with doped W atoms.”
“From the 15th century to the present day, Christian art has portrayed people who suffer from epilepsy as attributes in illustrations of Saint Valentine (SV). The objective of our Study was to interpret the works of art from a modern epileptological perspective on the basis of a collection of portrayals of SV in Europe that was as comprehensive as possible. The people depicted as attributes were analyzed with respect to their age, gender, social status, and possible seizure semiology. Three hundred forty-one illustrations of SV from Austria, Belgium, Croatia, Czech Republic, France, Germany, Hungary, Ireland.
