Metabolism of chlortoluron in tolerant species: possible role of cytochrome p-450 mono-oxygenases

1988

Summary Pathways of chlortoluron metabolism were compared in excised leaves of four tolerant species, namely wheat (Triticum aestivum var Clement), Bromus sterilis, Galium aparine and Veronica persica. The herbicide was principally detoxified by hydroxylation of the ring methyl in wheat and by N-dealkylation in Veronica persica. Both pathways were involved in Bromus sterilis and Galium aparine. Kinetic study of the degradation showed that capacity to form non-toxic conjugates could, at least partially, explain the tolerance of these species to chlortoluron. In plants treated with 1-aminobenzotriazole, a cytochrome P-450 enzyme inactivator, N-dealkylation of chlortoluron was little or not af…

Plant species identities and fertilization influence on arbuscular mycorrhizal fungal colonisation and soil bacterial activities

2016

International audience; Plant species influence soil microbial communities, mainly through their functional traits. However, mechanisms underlying these effects are not well understood, and in particular how plant/ microorganism interactions are affected by plant identities and/or environmental conditions. Here, we performed a greenhouse experiment to assess the effects of three plant species on arbuscular mycorrhizal fungal (AMF) colonization, bacterial potential nitrification (PNA) and denitrification activities (PDA) through their functional traits related to nitrogen acquisition and turnover. Three species with contrasting functional traits and strategies (from exploitative to conservat…

Follow-up of patients after revascularisation for peripheral arterial diseases: a consensus document from the European Society of Cardiology Working …

2019

International audience; Peripheral arterial diseases comprise different clinical presentations, from cerebrovascular disease down to lower extremity artery disease, from subclinical to disabling symptoms and events. According to clinical presentation, the patient's general condition, anatomical location and extension of lesions, revascularisation may be needed in addition to best medical treatment. The 2017 European Society of Cardiology guidelines in collaboration with the European Society for Vascular Surgery have addressed the indications for revascularisation. While most cases are amenable to either endovascular or surgical revascularisation, maintaining long-term patency is often chall…

Arrhythmic sudden cardiac death in a 3-year-old child with intimal fibroplasia of coronary arteries, aorta, and its branches

2001

Abstract We report an unusual case of “arrhythmic” sudden cardiac death in a 3-year-old child who died of ischemic myocardial lesions as a result of intimal fibroplasia of the coronary arteries. Also affected were the aorta and its major branches, whereas renal and mesenteric arteries, celiac trunk, and systemic veins were normal. Histopathologic examination showed severe concentric thickening of intima because of a proliferation of spindle-shaped cells (mesenchymal cells) set in an abundant extracellular matrix. In some vascular segments the intima was densely fibrotic and hyalinized. No significant inflammation, foam cells, cholesterol clefts, or other evidence of atheroma were present. T…

Groupe de travail COLUMA Bourgogne Franche-Comté : analyse et cartographie de la résistance aux herbicides sur céréales

2013

This working group made a survey and drew maps of herbicide resistances in cereal crops according to modes of action and weed species. These resistances concern mainly grass weeds but also one dicot weeds.

Fibrodisplasia arteriosa misconosciuta ad esito letale. Descrizione casistica e rivisitazione della letteratura

2007

gli autori presentano due casi di displasia fibromuscolare (DFM) oggetto di indagine giudiziaria per ipotizzata responsabilità professionale nell'operato dei sanitari all'esordio clinico e nell'approccio chirurgico. Viene sottolineata la necessità di una rapida risoluzione chirurgica in ambiente specialistico e l'importanza delle linee guida che devono essere rispettate nell'approccio al pziente

Classification of tall-forb vegetation in the Pamir-Alai and western Tian Shan Mountains (Tajikistan and Kyrgyzstan, Middle Asia)

2020

Aims: To complete the syntaxonomic scheme for tall-forb vegetation of the montane and alpine belts in the Pamir-Alai and western Tian Shan Mountains in Tajikistan and Kyrgyzstan with some remarks on its environmental predictors. Study area: Middle Asia: Tajikistan and Kyrgyzstan. Methods: A total of 244 relevés were sampled in 2013–2019 using the seven-degree cover-abundance scale of the Braun-Blanquet approach. These were classified with a modified TWINSPAN algorithm with pseudospecies cut-levels 0%, 5% and 25%, and total inertia as a measure of cluster heterogeneity. Diagnostic species were identified using the phi coefficient as a fidelity measure. NMDS was used to explore the relationsh…
