The nature of the adverse effects of wheat bran fractions on bread-making quality was studied. Two fractions of bran, representing different tissue layers and having different compositions, were used. The particle size of the bran fractions was varied by various milling techniques. All fractions were added to white flour and water addition was adjusted to obtain dough with a constant consistency. 相似文献

Necropsy examination of an adult Atlantic salmon (Salmo salar) from the Dalälven River in Sweden revealed numerous large, white nodules, with spherical cysts and granulomata in kidney and liver. Histopathology showed dark, septate, thin‐walled hyphae. The aetiologic agent was found to be an Ochroconis species (Venturiales) that differed from known fish‐associated species of the genus. Molecular phylogenetic studies of the culture (strain UIII09 = CBS 135766) demonstrated that Ochroconis globalis was concerned. The isolate proved to be susceptible to all investigated antifungals, as it is known for another Ochroconis species. The role of Ochroconis in opportunism of cold‐blooded animals was discussed, and the diagnostic methods using DNA sequences for routine identification of the fungus were proposed. 相似文献

The aim of this study was to determine the bioavailability and kinetics of the supposed anticarcinogen sulforaphane, the hydrolysis product of glucoraphanin, from raw and cooked broccoli. Eight men consumed 200 g of crushed broccoli, raw or cooked, with a warm meal in a randomized, free-living, open cross-over trial. Higher amounts of sulforaphane were found in the blood and urine when broccoli was eaten raw (bioavailability of 37%) versus cooked (3.4%, p ) 0.002). Absorption of sulforaphane was delayed when cooked broccoli was consumed (peak plasma time ) 6 h) versus raw broccoli (1.6 h, p ) 0.001). Excretion half-lives were comparable, 2.6 and 2.4 h on average, for raw and cooked broccoli, respectively (p ) 0.5). This study gives complete kinetic data and shows that consumption of raw broccoli results in faster absorption, higher bioavailability, and higher peak plasma amounts of sulforaphane, compared to cooked broccoli. 相似文献

A high intake of cruciferous vegetables is associated with a reduced risk of cancer and cardiovascular diseases. This protective effect has been linked to isothiocyanates, enzymatic hydrolysis products of glucosinolates. In this study, the metabolic fate of glucosinolates and isothiocyanates after ingestion of 19 different cruciferous vegetables was studied in three male subjects. After the consumption of 13 cruciferous vegetables (glucosinolate content, 0.01-0.94 mmol/kg) and six condiments (isothiocyanate content, 0.06-49.3 mmol/kg), eight different isothiocyanate mercapturic acids were determined in urine samples. Excretion levels after the consumption of raw vegetables and condiments were higher (bioavailability, 8.2-113%) as compared to cooked vegetables (bioavailability, 1.8-43%), but the excretion rate was similar (t1/2=2.1-3.9 h). Isothiocyanates in urine remain longer at a nonzero level after the consumption of glucosinolates from cooked vegetables, as compared to raw vegetables and condiments, and maximal levels in urine were reached about 4 h later. Isothiocyanate mercapturic acids can be used as a biomarker to reflect the active dose of isothiocyanates absorbed. 相似文献

Landscapes Toolkit: an integrated modelling framework to assist stakeholders in exploring options for sustainable landscape development 总被引:1,自引:1,他引:0
Iris C. Bohnet Peter C. Roebeling Kristen J. Williams Dean Holzworth Martijn E. van Grieken Petina L. Pert Frederieke J. Kroon David A. Westcott Jon Brodie 《Landscape Ecology》2011,26(8):1179-1198
At present, stakeholders wishing to develop land use and management change scenarios at the landscape scale and to assess
their corresponding impacts on water quality, biodiversity and economic performance, must examine the output of a suite of
separate models. The process is not simple and presents a considerable deterrent to making such comparisons and impedes the
development of more sustainable, multifunctional landscapes. To remedy this problem, we developed the Landscapes Toolkit,
an integrated modelling framework that assists natural resource managers, policy-makers, planners and local communities explore
options for sustainable landscape development. The Landscapes Toolkit links spatially-explicit disciplinary models, to enable
integrated assessment of the water quality, biodiversity and economic outcomes of stakeholder-defined land use and management
change scenarios. We use the Tully–Murray catchment in the Great Barrier Reef region of Australia as a case study to illustrate
the development and application of the Landscapes Toolkit. Results show that the Landscapes Toolkit strikes a satisfactory
balance between the inclusion of component models that sufficiently capture the richness of some key aspects of social-ecological
system processes and the need for stakeholders to understand and compare the results of the different models. The latter is
a prerequisite to making more informed decisions about sustainable landscape development. The flexibility of being able to
add additional models and to update existing models is a particular strength of the Landscapes Toolkit design. Hence, the
Landscapes Toolkit offers a promising modelling framework for supporting social learning and adaptive management through participatory
scenario development and evaluation as well as being a tool to guide planning and policy discussions at the landscape scale. 相似文献

Efficient bipedal robots based on passive-dynamic walkers 总被引:1,自引:0,他引:1
Passive-dynamic walkers are simple mechanical devices, composed of solid parts connected by joints, that walk stably down a slope. They have no motors or controllers, yet can have remarkably humanlike motions. This suggests that these machines are useful models of human locomotion; however, they cannot walk on level ground. Here we present three robots based on passive-dynamics, with small active power sources substituted for gravity, which can walk on level ground. These robots use less control and less energy than other powered robots, yet walk more naturally, further suggesting the importance of passive-dynamics in human locomotion. 相似文献

Although the gas chromatographic separation of the isomers of BHC was demonstrated two decades ago, the present AOAC method of analysis of BHC for gamma-isomer (lindane) content is based on a separation carried out on a liquid chromatographic partition column. A method of analysis has been developed that uses an OV-210 column for separation of the gamma-isomer from the other isomers and impurities in technical BHC. Di-n-propyl phthalate was chosen as an internal standard. The same system allows quantitation of lindane in lotion and shampoo after these products are extracted with ethyl acetate-isooctane (1 + 4). The analytical methods were subjected to a collaborative trial with 10 laboratories. The coefficient of variation for technical BHC was 2.83%. For the water-dispersible powder and emulsifiable concentrate, the coefficients of variation were 2.89% and 4.62%, respectively. Coefficients of variation for 1% lindane lotion and shampoo were 4.36% and 11.92%, respectively. The method has been adopted official first action. 相似文献
