Measurement of sap flow in roots of woody plants: a commentary     

Burgess SS  Adams MA  Bleby TM 《Tree physiology》2000,20(13):909-913

Measurements of sap flow in roots have recently been used to study patterns of resource acquisition by woody plants; however, the various thermometric methods employed have yielded disparate findings. These findings may be harmonized by accounting for the phenomenon of reverse sap flow in roots. We suggest that only methods capable of measuring slow and reverse rates of flow and that do not require assumptions of zero flow during the night are applicable to studies with roots. The heat ratio method and the constant power heat balance method fit these criteria, whereas the constant temperature heat balance, compensation heat pulse and thermal dissipation methods do not.  相似文献   

Development and use of a framework for characterising computer models of silvoarable economics     

A.R.?GravesEmail author  P.J.?Burgess  F.?Liagre  J.-P.?Terreaux  C.?Dupraz 《Agroforestry Systems》2005,65(1):53-65

A review of existing computer models of silvoarable¹ economics was undertaken for a project, entitled Silvoarable Agroforestry for Europe (SAFE), which aims to reduce uncertainty regarding the introduction and management of silvoarable systems in Europe. Because the published literature describing and comparing such models is sparse, a framework was developed and then used to characterise five computer models: POPMOD, ARBUSTRA, the Agroforestry Estate Model, WaNuLCAS, and the Agroforestry Calculator. Key characteristics described for each model were the background, systems modelled, objective of the economic analysis, economic viewpoint, spatial and temporal scales, generation and use of biophysical data, model platform and interface, and input requirements and outputs. Each of the models could produce a partial budget of the profitability of a silvoarable, arable, or forestry system at a one-hectare level using discounted cost–benefit analysis. Whilst the research models undertook the analysis from a viewpoint of a generic farmer, models developed for decision-support also included appraisals from the perspectives of tenants, share-croppers, and participants in a joint-venture. The two farm-scale models, ARBUSTRA and the Agroforestry Estate Model, could also be used to examine the feasibility of silvoarable systems on an existing business, and to determine the effects of heterogeneous land types and phased planting. The framework allows users to identify the pertinent issues for selecting or developing a particular model. The word ‘silvoarable’ is synonymous with the word ‘agrisilviculture’ described by Nair (An Introduction to Agroforestry, Kluwer Academic, 1983) and describes the same type of production system.

Effect of the citrus flavanone naringenin on oxidative stress in rats     

Andrade JE  Burgess JR 《Journal of agricultural and food chemistry》2007,55(6):2142-2148

Flavonoids are non-nutrient plant phenolic compounds proposed to provide health benefits in humans. The antioxidant and prooxidant effects of the citrus flavanone naringenin have been tested only in vitro. The dose-response effect of naringenin consumption was tested in weanling rats (n=6-8/group) with a 2x4 factorial design using high or low oxidative stress (Hox or Lox, respectively) diets, created by adequate or deficient amounts of vitamin E and selenium, with three increasing naringenin concentrations (30, 60, or 120 mg/kg of diet). Hox compared to Lox rats exhibited reduced growth and liver hypertrophy, which was not prevented by naringenin consumption. Also, Hox rats exhibited severalfold higher liver NAD(P)H:quinone oxidoreductase-1 activity, which was further elevated in proportion to naringenin intake, but this was not sufficient to protect against oxidative stress indicated by higher liver total aldehydes. In addition, dietary naringenin did not affect antioxidant nutrient status or physiological markers of growth under Lox conditions. Thus, dietary naringenin did not exhibit antioxidant or prooxidant effects in vivo in this rat model.  相似文献   

Use of a questionnaire to predict von Willebrand disease status and characterize hemorrhagic signs in a population of dogs and evaluation of a diagnostic profile to predict risk of bleeding          下载免费PDF全文

Hilary J. Burgess  J. Paul Woods  Anthony C.G. Abrams-Ogg  R. Darren Wood 《Canadian journal of veterinary research》2009,73(4):241-251

The objective of this study was to use a questionnaire 1) for characterization of hemorrhagic signs; 2) to assess its value as a predictor of von Willebrand Disease (vWD) status; and 3) for evaluation of the vWD diagnostic profile [platelet function analysis using the PFA-100, Collagen binding assay (vWF:CBA), and vWF antigen ELISA (vWF:Ag)], partial thromboplastin time (PTT) and Factor VIII activity (FVIII) as predictors of hemorrhagic risk. von Willebrand factor (vWF) concentration and function was assessed for each of the 165 canine participants using the vWD diagnostic profile. Hemorrhagic signs for each dog were obtained using a standardized questionnaire. Questionnaires were scored according to a previously prepared scoring key. Of the 165 dogs in the study, 43.6% had a low vWF concentration, with only 48.6% of dogs in this group having reports of hemorrhagic signs. Oral bleeding was the most commonly reported sign. The questionnaire had a sensitivity of 48.6% and a specificity of 78.5% for the prediction of vWD status. Using the Spearman correlation coefficient, a statistical association was found between the questionnaire and the vWD diagnostic profile components. However, this could not be translated into an ability to predict hemorrhage. The questionnaire allowed characterization of hemorrhagic signs in a large population of dogs over a range of vWF:Ag concentrations, and demonstrated that the vWD diagnostic profile was unsuccessful in the prediction of hemorrhagic risk. Although the sensitivity was insufficient for a screening tool, the questionnaire did have some discriminatory power in the prediction of vWD status.  相似文献

Feeding conjugated linoleic acid partially recovers carcass quality in pigs fed dried corn distillers grains with solubles     

White HM  Richert BT  Radcliffe JS  Schinckel AP  Burgess JR  Koser SL  Donkin SS  Latour MA 《Journal of animal science》2009,87(1):157-166

Dried corn distillers grains with solubles (DDGS) fed to swine may adversely affect carcass quality due to the high concentration of unsaturated fat. Feeding CLA enhances pork quality when unsaturated fat is contained in the diet. The effects of CLA on growth and pork quality were evaluated in pigs fed DDGS. Diets containing 0, 20, or 40% DDGS were fed to pigs beginning 30 d before slaughter. At 10 d before slaughter, one-half of each DDGS treatment group was fed 0.6% CLA or 1% choice white grease. Carcass data, liver- and backfat-samples were collected at slaughter. Longissimus muscle area, 10th-rib back-fat depth, last rib midline backfat depth, LM color, marbling, firmness and drip loss, and bacon collagen content were not altered by DDGS or CLA. Outer layer backfat iodine values were increased (P 0.05) for pigs fed DDGS. Feeding CLA decreased (P 相似文献
