The overall gender distribution was almost equal. Palate was the most frequent involved site, followed by alveolar mucosa and floor of the mouth.

Conclusions. The present study shows a higher proportion of malignant tumors and a tendency toward male predilection during the past decades. The overall data are consistent with hospital-based studies from Asia and series from other geographic regions. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2011;111:e32-e39)”
“In this work, we investigate electron transport Wnt activity across a carbon molecular junction consisting of a C-60 molecule

attached to two semi-infinite metallic open-end CNT leads in the coherent regime. Here, we put emphasis on topology of the molecular-electrode interface and gate voltage, and obtain the electrical transmission through the CNT/C-60/CNT structure, using the Green’s function method in the framework of a nearest neighbor tight-binding approximation. To this end, three Ruboxistaurin cell line different ways of coupling C-60 fullerene through one, five, and six carbon atoms to the CNT-leads in the direction of the longitudinal axis of the tube have been considered. Also, the current-voltage characteristic is calculated in the Landauer-Buttiker

formalism at room temperature. It is shown that the number of contact points between the electrodes and the molecule can play an important role in the electrical transport. Also, Selleck Belinostat the bond dimerization and a gate voltage

shift the molecular levels, where by adjusting the related parameters the electron conduction can be controlled. Our results show that the proposed structure gives rise to the resonance states and quasi-bound states (Fano resonances) close to -2.63 eV. These antiresonance states are related to the active region and independent from the coupling strength between the device and the leads. The numerical results may serve as important components of nanocircuits. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3602994]“
“BACKGROUND: The use of donation-after-circulatory-death (DCD) donors for lung transplantation has come into practice. In this study we investigated whether DCD lungs can be resuscitated after warm ischemia with normothermic ex vivo lung perfusion (EVLP).

METHODS: Four hours after cardiac arrest, beagle dogs were divided into two groups (n = 6 each): those with static cold storage (SCS group) and those with normothermic EVLP (EVLP group), for 3.5 hours. Physiologic lung functions were evaluated during EVLP. In both groups, the left lungs were then transplanted and reperfused for 4 hours to evaluate post-transplant lung functions. Lung tissue adenosine triphosphate (ATP) levels were measured at given time-points.

RESULTS: Lung oxygenation was significantly improved with EVLP (p < 0.01), and lung oxygenation at the end of EVLP significantly reflected post-transplant lung oxygenation (r = 0.99, p < 0.01).
