Five ca.tra.ed ma.e Iberia. pigs (100 ± 2 kg b.w.) fitted with T-sha.ed ilea. ca.nula. a. the termina. ileum were used to determine the effects of legume feeding on intestina. microbiota.composition. The diets were ba.ed on defa.ted soybea.

[目的]讨论火灾地区土壤保护的基本方法,旨在从生物多样性和美学价值方面,阐述新兴生物工程领域在修复与固结土壤,保护土壤免遭不同类型侵蚀,维持景观质量等方面中的应用。[方法]通过综述和评价现行生物工程技术在西班牙森林火灾后土壤保持和土壤修复中的应用,阐述了有关基本原理,并介绍了一些生物工程技术在受火灾影响的不同地区的成功应用案例。[结果]生物工程技术用于森林火灾后土壤保护和修复的重要基础知识部分仍基于土壤保持的一些传统原理,尤其在与具体干预的立地和简单技术应用的生态一致性方面。同时也不应低估新近土木工程的作用。这些土木工程技术(包括金属笼的使用)为生物要素(主要是植物物质)发挥更大作用提供了条件,而这些生物要素是在特定干预区气候或生物物理条件下发挥固结土壤作用的重要因素。与活体材料一起使用的还有各种生物物质,例如植物残留物,砍下的灌木,木质化元素,以及多种土工织物。这些技术可以归结分为4组主要形式:(1)土壤保护技术,(2)地面稳定技术,(3)重建技术组合,(4)其他稳定技术。[结论]用于土壤保护的生物工程技术提供了一种更为环保和具有长期有效性的方法。它同时具有耗资低,适应性强和提供多功能景观效益等优势。然而,生物技术也存在一些缺陷,例如人力资源需求,缺乏有关知识和合适的植物物质,特别是在一些干旱气候地区。尽管如此,生物工程方法在满足森林火灾影响后土壤保护的紧急干预措施这类新需求过程中表现出其正在崛起,有应用前途和快速发展的态势。

a.M: Infla.ma.ory bowel disea.es (IBD) a.e multifa.toria. pa.hologies of unknown etiology. One susceptibility locus, IBD5, ha. been ma.ped to chromosome 5q31. We a.a.yzed our Spa.ish cohorts of Crohn's disea.e (CD) a.d ulcera.ive colitis (DC) pa.ients to determine whether this locus is a.socia.ed with IBD, a.d to a.certa.n the ma.n clinica. phenotype influenced by this risk fa.tor. The kind of intera.tion, either genetic heterogeneity or epista.is, between this IBD5 susceptibility region a.d the NOD2/Ca.D15 gene muta.ions wa. studied a. well. Fina.ly, we a.sessed whether this locus ca. predict response to inflixima. thera.y. METHODS: a.ca.e control study wa. performed with 274 CD a.d 211 UC pa.ients recruited from a.single center a.d 511 hea.thy ethnica.ly ma.ched controls. Two polymorphisms were genotyped in the IBD5 locus a.d three in the Ca.D15/NOD2 gene. RESULTS: Our results evidence a.socia.ion only with CD especia.ly with the fistulizing phenotype a.d in the a.sence of NOD2/Ca.D15 va.ia.ts (muta.t a.lele frequency in pa.ients vs controls: OR = 2.03, 95% CI = 1.35-3.06, Pa.t genotype significa.tly increa.ed in CD pa.ients la.king response to inflixima.
