The intraoral buccal mucosal tumor from a 50-year-old man was a poorly differentiated carcinoma with sebaceous differentiation and expression of androgen receptor. Fordyce granules and a minor salivary gland

with a duct were identified in vicinity to the tumor. We discuss the differential diagnosis and histogenesis. The patient underwent surgery and adjuvant radiation therapy. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2010;110:e37-e40)”
“We investigate the applicability of a triple quantum Trichostatin A in vivo dot (TQD) device for memory operation, in which information is coded by the magnetization of a ferromagnetic (FM) electrode. In the presence of Rashba spin-orbit coupling, a high spin polarization of current can be generated in the TQD device to induce spin transfer switching of the FM electrode. We evaluate the spin current and spin torque via the Keldysh nonequilibrium Green’s function

method. The calculated spin torque can be reversed symmetrically by applying an opposite bias voltage, thus enabling current-induced magnetization switching to be applied for data writing. Additionally, the charge current shows a large modulation when the magnetization of the FM electrode is switched, a feature which can be utilized BI 2536 order for reading data. The ability to write and read data demonstrates the applicability of the TQD device for spin transfer torque-based memory. (C) 2011 American Institute of Physics. [doi:10.1063/1.3535545]“
“Tuberculosis remains an important global public health problem, with an estimated prevalence of 14 million individuals with tuberculosis worldwide in

2007. Because antibiotic treatment is one of the main tools for tuberculosis control, knowledge of Mycobacterium tuberculosis drug resistance is an important component for the disease control strategy. Although several gene mutations in specific loci of the M. tuberculosis genome have been reported as the basis for drug resistance, additional resistance mechanisms are now believed to exist. Efflux Cl-amidine concentration is a ubiquitous mechanism responsible for intrinsic and acquired drug resistance in prokaryotic and eukaryotic cells. Mycobacterium tuberculosis presents one of the largest numbers of putative drug efflux pumps compared with its genome size. Bioinformatics as well as direct and indirect evidence have established relationships among drug efflux with intrinsic or acquired resistance in M. tuberculosis. This minireview describes the current knowledge on drug efflux in M. tuberculosis.”
“An alternative design of vibration energy harvester was demonstrated to significantly increase the output power density. This design had two magnetic solenoids fixed at two sides of a spring supported hard magnet pair with anti-parallel magnetization, which produced a spatially inhomogeneous bias magnetic field for switching the flux inside the solenoids during vibration.
