Comparison of ear corn plus supplement, shelled corn plus protein supplement and complete mixed rations for growing and finishing swine
The purposes of this experiment were: (1) to compare and evaluate the effect of ear corn, shelled corn and a complete mixed ration when fed to growing and finishing swine; (2) to further determine the effect of each one on rate of gain; (3) to compare the feed efficiency of each type of feed in terms of total pounds required and the total cost of each; and (4) to determine the effect of each type of feed on backfat thickness
Fruit Production and Opportunities for Growers in Utah
This fact sheet discusses the state of the fruit industry in Utah, its impact on the Utah economy, as well as current challenges the fruit industry faces and opportunities for fruit growers moving forward. These challenges and opportunities underscore the importance of fruit to the state’s economy, as growers navigate urbanization, competition, and consumer preferences for locally grown produce. Fostering collaboration between consumers and growers will ensure a commitment to local agriculture and community support
Genome wide expression profiling reveals suppression of host defence responses during colonisation by Neisseria meningitides but not N. lactamica.
Both Neisseria meningitidis and the closely related bacterium Neisseria lactamica colonise human nasopharyngeal mucosal surface, but only N. meningitidis invades the bloodstream to cause potentially life-threatening meningitis and septicaemia. We have hypothesised that the two neisserial species differentially modulate host respiratory epithelial cell gene expression reflecting their disease potential. Confluent monolayers of 16HBE14 human bronchial epithelial cells were exposed to live and/or dead N. meningitidis (including capsule and pili mutants) and N. lactamica, and their transcriptomes were compared using whole genome microarrays. Changes in expression of selected genes were subsequently validated using Q-RT-PCR and ELISAs. Live N. meningitidis and N. lactamica induced genes involved in host energy production processes suggesting that both bacterial species utilise host resources. N. meningitidis infection was associated with down-regulation of host defence genes. N. lactamica, relative to N. meningitidis, initiates up-regulation of proinflammatory genes. Bacterial secreted proteins alone induced some of the changes observed. The results suggest N. meningitidis and N. lactamica differentially regulate host respiratory epithelial cell gene expression through colonisation and/or protein secretion, and that this may contribute to subsequent clinical outcomes associated with these bacteria
Chemical functionalization of emulsion-templated porous polymers by thiol–ene “click” chemistry
Highly porous polymers (polyHIPEs) have been prepared by the photopolymerization of high internal phase emulsions (HIPEs) with varying ratios of thiol and acrylate monomers. The resulting polymers have a nominal porosity of 80%, and are seen to have a well-defined, interconnected pore morphology, with average pore diameters ranging from 30 to 60 μm. The polyHIPE polymers have been shown using a colourimetric (Ellman's) assay to contain residual thiols which are reactive towards a range of (meth)acrylates (hexafluoroisopropyl acrylate, fluorescein O-acrylate and poly(ethylene glycol) methyl ether methacrylate). Functionalization was explored using thermally- and UV-initiated radical-mediated “click” reactions and an amine-catalysed Michael addition reaction. The extent of functionalization was investigated qualitatively and quantitatively using a range of techniques (solid state NMR spectroscopy; FTIR spectroscopy; X-ray photoelectron spectroscopy (XPS); observation of fluorescence); high levels of conversion (up to 90–95%) were observed for the thermally-initiated radical reaction and the Michael reaction
