“A Thoroughbred gelding in North America selleck compound was evaluated for Actinobacillus peritonitis on three different occasions over a 4-year period. At each presentation, peritoneal fluid had an elevated nucleated cell count (220,000-550,000 cells/mu L) characterised by non-degenerate neutrophils, no visible bacteria, an elevated total protein (4.6-5.5 g/dL) and bacterial culture yielding Actinobacillus spp. Actinobacillus peritonitis appears

to be a regional disease occurring in Australia and less commonly in New Zealand and North America. Recurrence, other than incomplete resolution, has not been previously reported. This case highlights the classical presentation, response to therapy and excellent prognosis despite the alarmingly abnormal peritoneal

fluid characteristic of Actinobacillus peritonitis and questions the role of parasite migration in the pathogenesis. Finally, this case is remarkable Fosbretabulin mouse because Actinobacillus peritonitis was recurrent over several years in an otherwise normal horse.”
“We present a methodology for implementing discrete-time signal processing operations, such as filtering, with molecular reactions. The reactions produce time-varying output quantities of molecules as a function of time-varying input quantities according to a functional specification. This computation is robust and independent of the reaction rates, provided that the GSK-J4 rate constants fall within coarse categories. We describe two approaches: one entails synchronization with a clock signal, implemented through sustained chemical oscillations; the other is self-timed or asynchronous. We illustrate the methodology by synthesizing a simple moving-average filter, a biquad filter, and a Fast Fourier Transform (FFT). Abstract molecular reactions for these filters and transforms are translated into DNA strand displacement reactions. The computation is validated through mass-action simulations of the DNA kinetics. Although

a proof of concept for the time being, molecular filters and transforms have potential applications in fields such as biochemical sensing and drug delivery.”
“Purpose: This study aims to identify and compare the relevance of barriers that nurses in nursing homes experience in medication management in Belgium.\n\nDesign: The mixed-method study started with an expert meeting in November 2008 and was followed by a cross-sectional survey in February-March 2009, questioning 246 nurses and 270 nurse assistants in 20 nursing homes.\n\nMethods: Twelve nurses represented nursing homes in an expert meeting and listed all barriers that might cause suboptimal medication management.
