Published 2005Staff ViewISSN: 1524-475XSource: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Sepsis remains the single most important cause for multiple organ failure and death following burn injury for which no effective treatment is currently available. Burn injury is associated with immunosuppression which promotes sepsis. Studies from our laboratory have demonstrated that levels of the antimicrobial peptide (AMP), human β-defensin-2, was significantly decreased in burned skin epithelia, absent in burn blister fluid and poorly expressed in lung during inhalation injury.We hypothesize that 1) deficient antimicrobial peptides in burn wound promote progressive colonization of pathogens in burn wounds and 2) replacing active peptide components will restore the antimicrobial activity in burn wounds. We have synthesized several cationic steroid antimicrobials (CSAs) which mimic naturally occurring AMPs functionally. In vitro experiments using one of these synthetic drugs with locally isolated common burn pathogen P. aeruginosa and S aureus demonstrate MIC values of 2.0 ± 0.3 μg/ml and 0.4 ± 0.1 μg/ml, respectively, indicating effectiveness of these compounds against burn pathogens. These drugs were tested for cytotoxicity on cultured human keratinocytes using MTT cell viability assay. Results indicate that these drugs are nontoxic to cultured keratinocytes at the level required for bacterial killing. Since theses drugs are membrane active compounds it will be hard for bacteria to develop resistance and there is a great potential to be developed for clinical treatment.Type of Medium: Electronic ResourceURL: -

Published 2002Staff ViewISSN: 1460-2695Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: High temperature isothermal fatigue (IF) and in-phase thermo-mechanical fatigue (TMF) tests in load control were carried out in cast hot work die steel. At the same load amplitude, the fatigue lives obtained in the in-phase TMF tests are lower than those obtained in the isothermal tests. Observations of fracture surface and the response of stress–strain reveal that cyclic creep in the tensile direction occurs and the intergranular cracks dominate in TMF tests, whereas cyclic creep in the compressive direction occurs and the path of the crack growth is mainly transgranular in IF tests. A model of life prediction, based on the Chaboche law, was discussed. Damage coefficients that are functions of the maximum temperature and the variation of temperature are introduced in the model so as to evaluate TMF lives in load control. With this method, the lifetime prediction gives results corresponding well to experimental data.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-0649Keywords: 42.65.-kSource: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract Mechanism transitions of Self-Pumped Phase Conjugation (SPPC) with wavelength and doping concentration are observed in KTN:Fe (KTa1 −x Nb x O3:Fe with x = 0.48) crystals. The SPPC mechanism in KTN: Fe (0.4 wt. %) crystal transforms from “Stimulated Photorefractive Backscattering and Four-Wave Mixing” (SPB-FWM) to “cat” (or total internal reflection) as the wavelength increases from 514.5 nm to 620 nm. SPPC at 514.5 nm is formed with the “cat” mechanism in a 0.2 wt. % doped KTN:Fe crystal, while with the SPB-FWM mechanism in a 0.4 wt. % doped one. These mechanism transitions are discussed with respect to the dependence of the backscattering gain coefficient of the crystals on wavelength and doping concentration.Type of Medium: Electronic ResourceURL: -
