Previous studies have indicated that engineered nanomaterials can be transferred through the food chain. However, their potential ecotoxicity to the environment is not fully understood. Here, we systematically evaluated the physiological behavior and toxicity of polyvinylpyrrolidone (PVP)-coated silver nanoparticles (AgNPs) using a food chain model from Escherichia coli (E. coli) to Caenorhabdi...
The “new” Russia will soon celebrate its tenth anniversary. Gone are the initial romantic notions of a rapid transition to a free-market democracy and a civil society. Instead, the stark reality has set in that the accumulated damage of 500-plus years of repressive, autocratic rule continues to haunt all efforts to reform. Russia finds itself in a centuries-old dilemma of a love-hate relationsh...
A 45-year-old male patient presented with a bilateral maculopathy following unprotected exposure of less than two minutes' duration to a manual metal arc welding unit. He had been receiving the drug fluphenazine for the previous 10 years for treatment of depression. We believe that the drug fluphenazine, which had accumulated in his retinal pigment epithelium, may have rendered him particularly...
Title of Document: PROGNOSTICS OF SOLDER JOINT RELIABILITY UNDER VIBRATION LOADING USING PHYSICS OF FAILURE APPROACH Jie Gu, Doctor of Philosophy (Ph.D.), 2009 Directed By: Chair Professor and Director, Michael G. Pecht, Department of Mechanical Engineering Physics-of-failure (PoF) is an approach that utilizes knowledge of a product’s life cycle loading and failure mechanisms to perform reliabi...
The life and condition of a mine truck frame are related to how the machine is used. Damage from stress cycles accumulated over time, measurements throughout needed monitor condition. This results in high demands on durability sensors, especially harsh mining application. To make monitoring system cheap robust, sensors already available vehicles preferred rather than additional strain gauges. m...
Long recognized to be potent suppressors of immune responses, Foxp3(+)CD4(+) regulatory T (Treg) cells are being rediscovered as regulators of nonimmunological processes. We describe a phenotypically and functionally distinct population of Treg cells that rapidly accumulated in the acutely injured skeletal muscle of mice, just as invading myeloid-lineage cells switched from a proinflammatory to...
