Incidence des graminées adventices sur l'ergot des céréales
2013
Several species of Claviceps, mainly Claviceps purpurea may develop during cereals growth in place of grains or on the grass weeds head. These fungi may produce sclerotia with alkaloids inside, unsafe for the whole harvest. In order to help growers and grain collect organizations to support good practices, several years trials have been followed up. Synthesis for those data allows to identify strong grass weeds incidence, mainly for black-grass and ryegrass on ergot of cereal contamination, multiplication and maintain.

Theoretical prediction of the chemiluminescence behaviour of the ergot alkaloids
2004
Abstract The present manuscript is dealing with the application of molecular connectivity calculations to predict the chemiluminescent behaviour of ergot alkaloids when they react with common strong oxidants in liquid phase. Twenty compounds were theoretically studied by means of a discriminant equation formerly published, being 19 of them predicted as chemiluminescent with a high probability. Empirical confirmation of the chemiluminometric behaviour is performed with the few soluble and commercially available ergot alkaloids. On the basis of these results, a new FIA-direct chemiluminescent method is proposed for the determination of the ergot presenting the higher light emission, the pharm…
Cerebroarthrodigital syndrome: A newly recognized formal genesis syndrome in three patients with apparent arthromyodysplasia and sacral agenesis, bra…
1980
We describe three patients with a complex syndrome of apparent arthromyodysplasia, dyscephaly, sacral agenesis, and hypoplastic digitis. Cause is unknown, but an environmental cause is suspected on the basis of ergotamine exposure in one case and diazoxide intake in another, together with suggestive similarities to anomalies seen in animals treated with these drugs and to calves with the Australian hydranencephaly/arthrogryposis syndrome caused by Akebane or Aino virus. Pathogenetically the primary defect may be a neural tube-neural crest dysplasia with multiple secondary and tertiary manifestations and deformities.
Le désherbage d’automne contre l’ergot du seigle les traitements herbicides d’automne, un levier chimique efficace de lutte contre l’ergot du seigle
2013
Context and study: Trials in field allowed to show a link between a good grass weeding (blackgrass and rye grass) and extent of ergot contaminations. Makhteshim Agan France and Arvalis tested on 15 trials in 2011-2012, 2 ureas, as isoproturon against blackgrass, alone or in pro-gram with a sulfonylurea, to evaluate their indirect effect against ergot. Field trials were set up on sensitive crops to ergot (rye, wheat and triticale) infested with artificial ergot contaminations and weed seeds sensible to ALS. Contaminations were evaluated first in field on weeds and on crop, and then on harvest, by assessing sclerotia and alkaloids content in harvested samples. results: For all evaluation mean…
Clavine alkaloids and derivatives as mutagens detected in the Ames test.
1992
Eight cytostatic clavines were investigated for mutagenicity in Salmonella typhimurium (reversion of the his-strains TA98, TA100, TA102 and TA1537), directly and in the presence of a mammalian xenobiotic metabolizing system, S9 (NADPH-fortified postmitochondrial fraction of liver homogenate from Aroclor 1254-treated rats). Four compounds (festuclavine, 17-bromofestuclavine, 1-allylelymoclavine and 1-methyllysergol methyl ether) were direct mutagens, whose activity was enhanced in the presence of S9. The other compounds (1-cyclopentylfestuclavine, 13-bromo-1-cyclopropylmethylfestuclavine, 6-cyano-1-propyl-6-norfestuclavine and 6-allyl-1-propyl-6-norfestuclavine) showed mutagenic effects only…
Influence of prebiotics, probiotics and protein ingredients on mycotoxin bioaccessibility
2015
The aim of this study was to investigate the influence of prebiotic compounds (cellulose and inulin), food ingredients (milk whey, β-lactoglobulin and calcium caseinate) and several probiotic microorganisms on the bioaccessibility of beauvericin (BEA), enniatins (ENs A, A1, B, B1), deoxynivalenol (DON) and zearalenone (ZEA) present in wheat crispy bread produced with wheat flour previously fermented with F. tricinctum, F. culmorum and G. zeae. The bioaccessibility of mycotoxins was determined by a dynamic simulated gastrointestinal digestion system, imitating the human digestive physiological conditions of the gastrointestinal tract. Mycotoxins were determined in the simulated intestinal fl…
Crossover, double-blind clinical trial comparing almotriptan and ergotamine plus caffeine for acute migraine therapy
2007
In this randomized, double-blind, crossover clinical trial, adult patients treated two migraine attacks: one with almotriptan 12.5 mg and the other with ergotamine 2 mg plus caffeine 200 mg. Treatment with almotriptan was associated with a significantly greater proportion of patients achieving 2-h pain free (20.9% vs. 13.7%; P < 0.05) and 2-h pain relief (57.7% vs. 44.5%; P < 0.01) compared with ergotamine plus caffeine therapy; significant differences were not seen at 1 h. Rates for sustained pain free and sustained pain free plus no adverse events (AEs) also were significantly greater after almotriptan treatment than after the use of ergotamine plus caffeine (P < 0.05). Almotriptan was as…
Balansen mellom kontekstuelle krav og pasientenes behov : ergoterapeuters erfaringer knyttet til eldre pasienters overgangsfase fra sykehus til eget …
2014
Background and aim: Coping in daily activities when discharged from hospital to own home can be challenging for older people. Internationally, there is a number of studies on this topic, but similar studies in Norway and Nordic countries seem to be scarce. The aim of this study was to illuminate occupational therapists’ experiences of how to promote coping of daily activities in older patients who are discharged from hospital to home. Methods: A qualitative design with individual interviews was used. A purposive sample of eight occupational therapists were included, four worked in hospitals and four in community health services, respectively. Initially the interviews had an open form, but a…
Projekts: Uzņēmuma "Veselības zona" dibināšana
2021
Projekta ideja ir veselības aprūpes uzņēmuma “Veselības zona” dibināšana Rēzeknē, Lubānas ielā 35, kurā tiks sniegti fizioterapeita, ergoterapeita un masiera veselību saglabājoša, veicinoša un rehabilitējoša rakstura pakalpojumi. Uzņēmuma dibināšana plānota 2022. gada 3. janvārī, un tā juridiskā forma būs sabiedrība ar ierobežotu atbildību (turpmāk – SIA). Plānots, ka uzņēmuma pamatkapitāls būs 35 000 EUR, vienas kapitāla daļas vērtībai esot 1 000 EUR. Kapitāla daļas tiks sadalītas attiecībā 10 pret 25 starp uzņēmuma īpašniekiem X un Y. Plānots, ka īpašnieks X segs ar uzņēmējdarbības uzsākšanu saistītās izmaksas, savukārt īpašnieks Y nodrošinās mantisko ieguldījumu – uzņēmuma telpas.
