Abstract: Topical pimecrolimus is an alternative treatment of atopic dermatitis. However, rare cases of malignancy have been reported with their use. This study was performed to investigate the possible geno-or cytotoxic effect in mouse bone marrow caused by systemic absorption of pimecrolimus 1% cream. In order to determine this, induction of micronucleated erythrocytes (MNE) in mouse peripheral blood was determined after the cutaneous application of three different doses, daily for 5 consecutive days. No differences were found in frequencies of polychromatic erythrocytes, MNE, and micronucleated polychromatic erythrocytes in the different groups of study. In conclusion, under described conditions, no geno-or cytotoxic effects were detected after the cutaneous application of pimecrolimus.

Nanjundaiah, G.",,"2010",,"Power electronic converters have evolved rapidly, both in terms of available electronic switching devices & converter topologies. The evolutions from thyristor-based 12-pulse converters to Voltage Source Converters (VSCs) to Modular Multilevel Converters (MMCs) have placed increasingly onerous demands on simulation technology, in particular real-time digital simulators. The relatively high carrier frequencies in PWM-based converters require time-steps in the range of 10 to 50 ?s, typical of what may be achieved using standard INTEL/AMD multi-core processors. Today's MMC converters add to the challenge through large number of I/Os required to monitor the voltages of a large number of cells & to individually control a very large number of IGBT switches. In this paper the evolution of modern real-time digital power-system simulator is presented - the hardware/software challenges & solutions, leading to development of a commercially available a COTS-based simulator. Its efficacy with a simulation of an MMC-based back-to-back HVDC bipolar interconnecting two AC networks is presented. Such AC-DC-AC converter system presents challenges in terms of both the requirement of a small time step, as well as a very large number if I/O channels.",,,,,,"10.1109/PEDES.2010.5712570",,,"http://hdl.handle.net/20.500.12104/45385","http://www.scopus.com/inward/record.url?eid=2-s2.0-79952728072&partnerID=40&md5=55c42bb647705e0ae8570323952cc395",,,,,,,,"2010 Joint International Conference on Power Electronics, Drives and Energy Systems, PEDES 2010 and 2010 Power India",,,,,,"Scopus",,,,,,"FPGA; HIL; HVDC; IGBT; MMC; Power quality; Real-time simulation; VSC",,,,,,"Today's power system simulation challenge: High-performance, scalable, upgradable and affordable COTS-based real-time digital simulators",,"Conference Paper" "47170","123456789/35008",,"Aguilar, O., Departamento de Física, Universidad de Guadalajara, Revolución 1500, 44420 Guadalajara, Jalisco, Mexico; Klimov, A.B., Departamento de Física, Universidad de Guadalajara, Revolución 1500, 44420 Guadalajara, Jalisco, Mexico; de Guise, H., Department of Physics, Lakehead University, Thunder Bay, Ont.

de Guise, H.",,"2006",,"We investigate the possibilities of controlling and reconstructing the state of a single three-level atom. We propose a physical scheme where information about the atomic state is extracted by measuring the total number of excitations after successive application of electromagnetic field pulses. We show that, in the non-degenerate case (different transition frequencies for different atomic transitions), a three-level atom is completely controllable and its state can be completely reconstructed. In the degenerate case (when both atomic transitions are identical), we consider two dynamically inequivalent configurations, ? and ?. In this case, we show that the density matrix can always be completely reconstructed whereas their respective system cannot be completely controlled. We explain why this last incompatibility between control and tomography arises. " 2006 Elsevier B.V. All rights reserved.
