Haemolytic anaemia in cattle in NSW associated with Theileria infections     

MM Izzo  I Poe  N Horadagoda  AJ De Vos  JK House 《Australian veterinary journal》2010,88(1-2):45-51

Several outbreaks of anaemia, jaundice, abortion and mortality in cattle in New South Wales were attributed to the intracellular parasite, Theileria buffeli . Disease occurred predominantly in periparturient animals that had been moved from inland to coastal areas. Diagnosis was made via exclusion of other causes of haemolytic anaemia and observation of the parasite in blood smears. Treatments included both registered and non-registered products. There is a possibility of a new strain of Theileria sp. in Australia and the possible vectors encountered in NSW are discussed.  相似文献

Sorghum extrusion increases bioavailability of catechins in weanling pigs     

Gu L  House SE  Rooney LW  Prior RL 《Journal of agricultural and food chemistry》2008,56(4):1283-1288

Catechins and procyanidins are beneficial for human health; however, their bioavailability is low. The effect of food processing on catechin bioavailability from sources containing predominantly procyanidins has not been studied. The sumac sorghum mixture (50% whole grain+50% bran) used in this study contained catechins, procyanidins dimers, and polymers at 0.08, 0.6, and 26.4 mg/g, respectively. Extrusion decreased the polymeric procyanidins by 48% to 22 mg/g while increasing catechins (50%) and dimers (64%) to 0.12 and 1.0 mg/g, respectively. Six weanling pigs (8.9+/-1.1 kg) received a single dose by gavage of the sorghum mixture (7 g/kg0.75), the sorghum mixture extrudate, or white sorghum (50% whole grain+50% bran) in a randomized crossover design. Treatments were separated by a 7-day washout period. Blood was drawn at 0, 1, 2, and 4 h. Plasma catechin, 3'-O-methylcatechin, 4'-O-methylcatechin, epicatechin, 3'-O-methylepicatechin, and 4'-O-methylepicatechin peaked at 1 h and were 18, 43, 1, 0.7, 0.7, and 0.3 nmol/L for pigs receiving sorghum, respectively. Plasma levels in pigs receiving extruded sorghum were 66, 110, 2, 16, 8, and 11 nmol/L, respectively. Plasma levels of catechin, 3'-O-methylcatechin, and the total catechins were higher in pigs fed extruded sorghum at 1, 2, and 4 h postdose (P相似文献   

Occurrence and mobility of the insecticide permethrin in rivers in the Southern Humber catchment,UK     

W A House  J L A Long  J E Rae  A Parker  D R Orr 《Pest management science》2000,56(7):597-606

The synthetic pyrethroid insecticides cis‐ and trans‐permethrin are widely used, particularly in sheep‐dips and for mothproofing within the textile industry. This study aims to establish the concentrations and mobility of permethrin within rivers in the Humber catchment, which contain some of the highest densities of wool‐scouring activity in the world. Our approach was to utilise three different surveys: (a) weekly and storm‐responsive sampling of ‘whole waters’ in the rivers Aire, Ouse, Don, Trent and Calder; (b) intensive sampling of ‘whole waters’ and suspended sediments in the rivers Aire (0.5 h) and Calder (1 h); (c) a bed‐sediment survey of the River Calder. Sediments were extracted by supercritical fluid extraction and all samples were analysed by gas chromatography with mass spectrometry. Results demonstrated the presence of permethrin in ‘whole waters’ and sediments, particularly in the rivers Aire and Calder, and at concentrations in the bed‐sediment likely to cause ecotoxicological effects to benthic macro‐invertebrates. Mass‐balance calculations indicated some loss of permethrin from the water column during transport, with the greatest losses at low river‐discharge. Isomer ratios (trans:cis) give retention times of permethrin in different components of the system as ‘whole water’ < suspended sediments < bed‐sediments, with estimates of 4–26 days for suspended sediments and a maximum of 103–125 days for surface bed‐sediments. © 2000 Society of Chemical Industry  相似文献

Grassland vegetation changes and nocturnal global warming   总被引：4，自引：0，他引：4

Global minimum temperatures (TMIN) are increasing faster than maximum temperatures, but the ecological consequences of this are largely unexplored. Long-term data sets from the shortgrass steppe were used to identify correlations between TMIN and several vegetation variables. This ecosystem is potentially sensitive to increases in TMIN. Most notably, increased spring TMIN was correlated with decreased net primary production by the dominant C4 grass (Bouteloua gracilis) and with increased abundance and production by exotic and native C3 forbs. Reductions in B. gracilis may make this system more vulnerable to invasion by exotic species and less tolerant of drought and grazing.  相似文献   

Rotation of a single molecule within a supramolecular bearing     

JK Gimzewski  C Joachim  RR Schlittler  V Langlais  H Tang  I Johannsen 《Science (New York, N.Y.)》1998,281(5376):531-533

Experimental visualization and verification of a single-molecule rotor operating within a supramolecular bearing is reported. Using a scanning tunneling microscope, single molecules were observed to exist in one of two spatially defined states laterally separated by 0.26 nanometers. One was identified as a rotating state and the other as an immobilized state. Calculations of the energy barrier for rotation of these two states show that it is below the thermal energy at room temperature for the rotating state and above it for the immobilized state.  相似文献

Abstract. The interactions of P with soils and sediments are examined in the context of transport processes from land, through rivers to estuaries and coastal waters. In soil erosion, selective size fractionation and preferential sorption to finer solids is crucial in the transport of P to water courses. Problems in quantifying the sorption affinity and equilibrium phosphate concentration (EPC) of mixtures of different soils and sediments are identified. Riverine transport of P by suspended solids is usually very important and examples of the changes in the amount and composition of particulate P (PP) concentration during storm events are discussed. Increased P content of solids during the first autumn storms, probably reflect the resuspension of accumulated stream bed-deposits. The fate of P in estuaries and their importance as possible long-term sinks of P are discussed. The relatively high concentrations of dissolved P associated with riverine inputs are to some extent buffered by the relatively high concentrations of suspended sediments resulting from tidal flows. Phosphorus may be released during transport to the sea due to decreases in the EPC, increases in salinity and release from bottom sediments as a result of low oxygen conditions.  相似文献
