TL;DR: Bone strength, as indicated by pSSI, is compromised in children with CP due to smaller and thinner bones, not due to lower cortical bone density.

TL;DR: Different influences of weather and land cover on important mosquito species in the Northern Great Plains region are revealed, which can be used to improve local vector control strategies and West Nile virus prevention efforts.
Abstract: This study compared the spatial and temporal patterns of Culex tarsalis Coquillett and Aedes vexans Meigen populations and examined their relationships with land cover types and climatic variability in Sioux Falls, SD. Between 24 and 30 CDC CO2-baited light traps were set annually in Sioux Falls from May to September 2005–2008. Land cover data were acquired from the 2001 National Land Cover Dataset and the percentages of selected land cover types were calculated within a 600-m buffer zone around each trap. Meteorological information was summarized from local weather stations. Cx. tarsalis exhibited stronger spatial autocorrelation than Ae. vexans. Land cover analysis indicated that Cx. tarsalis was positively correlated with grass/hay, and Ae. vexans was positively correlated with wetlands. No associations were identified between irrigation and the host-seeking population of each species. Higher temperature in the current week and 2 wk prior and higher precipitation 3–4 wk before collection of host-seeking adult mosquitoes had positive influences on Cx. tarsalis abundance. Temperature in the current week and rainfall 2–3 wk before sampling had positive influences on Ae. vexans abundance. This study revealed the different influences of weather and land cover on important mosquito species in the Northern Great Plains region, which can be used to improve local vector control strategies and West Nile virus prevention efforts.

TL;DR: In this article, four marketing methods for slaughter cattle were analyzed and examined for pricing efficiency, and it was found that greater price discrimination occurred as carcass information increased, which led to greater dispersion of profit from one marketing method to another.
Abstract: Four marketing methods for slaughter cattle were analyzed and examined for pricing efficiency. Profits per head were found to be significantly different under the various marketing methods. Greater price discrimination occurred as carcass information increased. Increased price discrimination led to greater dispersion of profit from one marketing method to another. Different marketing methods appeared to send different production signals to producers. The desires of the consumer for less fat and a high-quality product did not appear to be reaching the producers in the form of profit incentives under the most widely used marketing method. © 1993 John Wiley & Sons, Inc.

TL;DR: The results demonstrated that determination of the organic composition of SESom during batch culturing is feasible, which makes SESOM amenable to studying the ecophysiology of a range of soil bacteria growing on soil-dissolved organic matter under more defined laboratory conditions.
Abstract: We investigated the composition of soil-extracted solubilized organic and inorganic matter (SESOM) pre- pared from three different soils. Growth of various bacterial strains in these soil extracts was evaluated to find appro- priate conditions for ecophysiological approaches. Analysis of SESOM by 1 H-NMR and gas chromatography/mass spectrometry revealed a complex mixture of organic com- pounds. An oak forest SESOM supported the growth of several gram-positive and gram-negative soil-derived het- erotrophic bacteria, whereas beech forest and grassland soil extracts did not. A metabolomic approach was performed by determining the extracellular metabolite profile of Bacillus licheniformis in SESOM. The results demonstrated that determination of the organic composition of SESOM during batch culturing is feasible. This makes SESOM amenable to studying the ecophysiology of a range of soil bacteria growing on soil-dissolved organic matter under more defined laboratory conditions. SESOM may also increase success in isolating previously uncultured or novel soil bacteria. Cell populations and the corresponding extra- cellular medium can be obtained readily and specific compo- nents extracted, pavingthe way for proteomic, transcriptomic, and metabolomic analyses. The synthetic carbon mixture based on SESOM, which mimics soil abilities, shows a positive impact on higher cell yields and longer cultivation time for biotechnological relevant bacteria.

TL;DR: The results suggest that a regulatory loop involving miR160/ARFs governs root and nodule organogenesis in M. truncatula.
Abstract: Auxin action is mediated by a complex signalling pathway involving transcription factors of the auxin response factor (ARF) family. In Arabidopsis, microRNA160 (miR160) negatively regulates three ARF genes (ARF10/ARF16/ARF17) and therefore controls several developmental processes, including primary and lateral root growth. Here, we analysed the role of miR160 in root development and nodulation in Medicago truncatula Gaertn. Bioinformatic analyses identified two main mtr-miR160 variants (mtr-miR160abde and mtr-miR160c) and 17 predicted ARF targets. The miR160-dependent cleavage of four predicted targets in roots was confirmed by analysis of parallel analysis of RNA ends (PARE) data and RACE-PCR experiments. Promoter-GUS analyses for mtr-miR160d and mtr-miR160c genes revealed overlapping but distinct expression profiles during root and nodule development. In addition, the early miR160 activation in roots during symbiotic interaction was not observed in mutants of the nodulation signalling or autoregulation pathways. Composite plants that overexpressed mtr-miR160a under two different promoters exhibited distinct defects in root growth and nodulation: the p35S:miR160a construct led to reduced root length associated to a severe disorganisation of the RAM, whereas pCsVMV:miR160a roots showed gravitropism defects and lower nodule numbers. Our results suggest that a regulatory loop involving miR160/ARFs governs root and nodule organogenesis in M. truncatula.
