Study of enzymatic activity in human neuroblastoma cells SH-SY5Y exposed to zearalenone's derivates and beauvericin.
2021
Abstract Beauvericin (BEA), α-zearalenol (α-ZEL) and β-zearalenol (β-ZEL), are produced by several Fusarium species that contaminate cereal grains. These mycotoxins can cause cytotoxicity and neurotoxicity in various cell lines and they are also capable of produce oxidative stress at molecular level. However, mammalian cells are equipped with a protective endogenous antioxidant system formed by no-enzymatic antioxidant and enzymatic protective systems such as glutathione peroxidase (GPx), glutathione S-transferase (GST), catalase (CAT) and superoxide dismutase (SOD). The aim of this study was evaluating the effects of α-ZEL, β-ZEL and BEA, on enzymatic GPx, GST, CAT and SOD activity in huma…

La conférence du Columa 2013 racontée par des étudiants AgroSup-Dijon
2014
Document accessible depuis la notice de ProdInra : https://prodinra.inra.fr/?locale=en#!ConsultNotice:306111; La 22e conférence du Columa de l’AFPP, tenue à Dijon du 11 au 13 décembre 2013, a été suivie par des étudiants d’AgroSup-Dijon. Ils rendent compte ici de ce qu’ils en ont retenu. Ils analysent particulièrement les sessions : – « Nuisibilité » des adventices (indirecte, ex. : favoriser l’ergot, et directe). – « Cultures méditerranéennes et tropicales » (différences Dom-Tom/autres pays, techniques émergentes). – « Résistance » (extension, mécanismes, facteurs de risque). – « Transfert aux milieux » (facteurs de risque de pollution des eaux, suivis et modélisation pour les prévoir). – …
Purification and partial amino acid sequences of the enzyme vinorine synthase involved in a crucial step of ajmaline biosynthesis.
2004
The acetyl-CoA-dependent enzyme vinorine synthase was isolated from hybrid cell suspension cultures of Rauvolfia serpentina and Rhazya stricta. The sarpagan-type alkaloid gardneral was used as a substrate of the enzyme leading to the ajmalan-type 10-methoxyvinorine. An HPLC-based assay was developed to monitor vinorine synthase activity, which allowed establishing a five step purification procedure combining anion exchange, hydrophobic interaction, hydroxyapatite and gel filtration. Purification resulted in a yield of 0.2% and an approximately 991-fold enrichment of the acetyltransfer activity. SDS-PAGE analysis showed a Mr for the enzyme of approximately 50 kDa. The four peptide fragments …
Vegetative and Reproductive Behaviour of Vitis vinifera L. (cv. ‘Cabernet Sauvignon’) Vines Growing Under Non-Irrigated Conditions and Moderate Water…
2007
An experiment was carried out to evaluate the effect of different levels of water stress and different irrigation systems to the vegetative and reproductive behaviour of Cabernet Sauvignon ines/140Ru, vertically trained, during the growing season 2003-2004. The vineyard was located in Sicily (in the south of Italy); the soil was loamy-sand and the climate semi-arid. Were compared five treatments: four treatments irrigated, maintaining a moderate water stress level, by drip irrigation (T1) and sub-irrigation (T2, T3 and T4) and one treatment non-irrigated (T5). The sub-irrigation treatments were different by the number and the distance of the water tubes by the rows of vines. The results sho…
Tomato leaf miner Tuta absoluta (Meyrick,1917) (Lepidoptera: Gelechiidae) The old and new challenge
2014
The term Phytosanitary exists within many of the modern and old scientific terms such as: organic farming, plant protection, integrated pest management, national and international movement of plant germplasm, biosecurity, good agricultural practices and others. There are many aspects within those related terms. All those terms have common interests of which the pests' risk be avoided and the environmental health is achieved. Consequently preventive measures, precaution measures and effective testing procedures are required. The study problem is the pest Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae), the Tomato leaf miner, this pest is one of the most devastating pests affecting T…
Pathogenicity bioassays of isolates of Beauveria bassiana on Rhynchophorus ferrugineus
2012
BACKGROUND:The control ofRhynchophorusferrugineus (Olivier), themainpalmpest in theMediterraneanBasin, is problematic because of its biology and the current restrictions inmany European countries on the use of chemical insecticides in urban areas. Entomopathogenic fungi have been studied as potential biological control agents, but information on their natural incidence is limited. Strains of Beauveria bassiana (Balsamo) Vuillemin were isolated from symptomatic insects collected on dead palms, and their pathogenicity against different instars of R. ferrugineus was evaluated in the laboratory. RESULTS: The overall percentage of infected insects found in Canary palms was 7%. In laboratory bioa…
Use of biorational insecticides for the control of Tuta absoluta (Meyrick) infestations on open field tomato
2012
Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), the tomato leaf miner, is one of the most devastating pests affecting tomato crops in Italy. Management of T. absoluta was assessed in open-field tests using three biorational insecticides, Azadirachtin, Bacillus thuringiensis var. kurstaki, and Beauveria bassiana, and a combination of three synthetic insecticides, Emamectin, Indoxacarb and Metaflumizone, as a control treatment. Our results showed that only the combination of Azadirachtin – B. thuringiensis was able to reduce the impact of tomato leaf miner on the fruit’s marketable production similarly to the control treatment. This finding suggests that biorational insecticides are a goo…
