Localization of alkylresorcinols in wheat,rye and barley kernels 总被引:1,自引:0,他引:1

Cereal alkylresorcinols (AR), a group of phenolic lipids mainly found in the outer parts of wheat and rye kernels, are currently being studied for the possibility to use them as biomarkers for the intake of whole grain wheat and rye foods. In this work, AR were localised in grains by using light microscopy and gas chromatographic analysis of hand-dissected botanical and pearling fractions. GC-analysis of hand-dissected fractions showed that more than 99% of the total AR content was located in an intermediate layer of the caryopsis, including the hyaline layer, testa and inner pericarp. Microscopic examination showed that the outer cuticle of testa/inner cuticle of pericarp was the exact location, and that no AR were found in the endosperm or in the germ, suggesting that AR could be used as a selective marker of testa. 相似文献

Background
Serum N‐terminal pro‐C‐natriuretic peptide (NT‐proCNP) concentration at hospital admission has sufficient sensitivity and specificity to differentiate naturally occurring sepsis from nonseptic systemic inflammatory response syndrome (SIRS). However, little is known about serum NT‐proCNP concentrations in dogs during the course of sepsis.Objective
To determine serum NT‐proCNP and cytokine kinetics in dogs with endotoxemia, a model of canine sepsis.Samples
Eighty canine serum samples.Methods
Eight healthy adult Beagles were randomized to receive Escherichia coli lipopolysaccharide (LPS, 5 μg/kg) or placebo (0.9% NaCl) as a single IV dose in a randomized crossover study. Serum collected at 0, 1, 2, 4, and 24 hours was stored at −80°C for batch analysis. Serum NT‐proCNP was measured by ELISA and 13 cytokines and chemokines by multiplex magnetic bead‐based assay.Results
Serum NT‐proCNP concentrations did not differ significantly between LPS‐ and placebo‐treated dogs at any time. When comparing serum cytokine concentrations, LPS‐treated dogs had higher interleukin‐6 (IL‐6), IL‐10, TNF‐α and KC‐like at 1, 2, and 4 hours; higher CCL2 at 1, 2, 4, and 24 hours; and higher IL‐8 and CXCL10 at 4 hours compared to placebo‐treated dogs. There were no differences in serum GM‐CSF, IFN‐γ, IL‐2, IL‐7, IL‐15 or IL‐18 between LPS‐ and placebo‐treated dogs.Conclusions and Clinical Importance
Serum NT‐proCNP concentration does not change significantly in response to LPS administration in healthy dogs. Certain serum cytokine and chemokine concentrations are significantly increased within 1–4 hours after LPS administration and warrant further investigation as tools for the detection and management of sepsis in dogs. 相似文献7.
研究了在重金属镉胁迫条件下,大弹涂鱼(Boleophthalmuspectinirostris)肝脏黄嘌呤氧化酶活性的变化。重金属镉胁迫12h时0·5mg/LCd2 组XOD酶活性和对照组比较显著升高(P<0·05);胁迫24h时,大弹涂鱼0·05mg/LCd2 组肝脏的XOD酶活性和对照组比较极显著升高(P<0·01),而0·5mg/LCd2 组酶活性结果却降低;恢复3d时0·5mg/LCd2 又极显著升高(P<0·01)。在镉胁迫解除5d时,3个浓度组的酶活性均极显著降低(P<0·01),其中0·05mg/LCd2 组和0·5mg/LCd2 组的酶活性和对照组酶活性比较无显著差异(P>0·05),5mg/LCd2 组的酶活性极显著低于对照组的酶活性(P<0·01)。实验结果表明,大弹涂鱼肝脏黄嘌呤氧化酶活性对水体中镉污染敏感,有可能用做海洋环境污染的生物标记。 相似文献

Whole cell fatty acid (WCFA) compositions of three different structures of ectomycorrhizal (ECM) fungi: sporocarps, pure culture mycelia and ectomycorrhizas were analysed to evaluate the potential use of fatty acid profiles as biomarkers for ECM fungi and ectomycorrhiza-associated bacteria. Sporocarps of Amanita muscaria, Amanita rubescens, Lactarius rufus, Lactarius thejogalus, Leccinum scabrum, Paxillus involutus, Russula foetens, Russula rosea, Russula vesca, Suillus grevillei, Tylopilus felleus, Xerocomus badius, Xerocomus subtomentosus, pure cultures of A. muscaria, P. involutus, X. badius, X. subtomentosus, Suillus bovinus Suillus luteus and seven ectomycorrhizal morphotypes of Norway spruce were examined. Our results revealed species-specific composition of fatty acids of fungal sporocarps and pure culture mycelia. Ectomycorrhizal morphotypes distinguished and identified by morphological and molecular methods (PCR-RLFP and sequencing) created specific fatty acid profiles. The dominating fatty acids in pure cultures and sporocarps were 18:2ω6,9, 18:1ω9 and 16:0, whereas ectomycorrhizas also contained plant and bacterial specific fatty acids. Especially, fatty acids specific to Gram-positive bacteria 15:0 anteiso and 17:0 anteiso were present in relatively high amounts and suggested that these bacteria are dominating in the examined Norway spruce mycorrhizosphere. In conclusion, our results show that fatty acid based methods can be useful in studies of ectomycorrhizal fungi, both as a quick method for differentiation of fungal species and also in studies of mycorrhiza-associated microorganisms in the field. 相似文献

Parasitic infections constitute an important group of diseases in sheep concerning the health status, welfare and productivity. On a global scale, there are considerable differences concerning the epidemiological situation with respect of the various parasite species. However, there are also numerous species, which occur on all continents and, potentially, in every country. Accordingly, the present review aims to providing an overview about the recent developments in methods and technologies for the laboratory diagnosis of parasite infections in sheep. Following in principle a systematic order the review encompasses publications addressing the diagnosis of helminthes (i.e., trematodes, cestodes and nematodes) and arthropod species. New approaches using conventional (e.g., microscopic), immunological and molecular techniques are being considered. The diagnosis of anthelmintic resistance is highlighted separately, due to its significant importance. The review ends with an outlook into the future by discussing most recent technological advances, which might become of use for the diagnosis of parasite infections in sheep in the future. 相似文献
