Diversity of Pharmacological Properties in Chinese and European Medicinal Plants: Cytotoxicity, Antiviral and Antitrypanosomal Screening of 82 Herbal…
2011
In an extensive screening, the antiviral, antitrypanosomal and anticancer properties of extracts from 82 plants used in traditional Chinese medicine and European phytomedicine were determined. Several promising plants that were highly effective against hepatitis B virus (HBV), bovine viral diarrhoea virus (BVDV)—a flavivirus used here as a surrogate in vitro model of hepatitis C virus, trypanosomes (Trypanosoma brucei brucei) and several cancer cell lines were identified. Six aqueous extracts from Celosia cristata, Ophioglossum vulgatum, Houttuynia cordata, Selaginella tamariscina, Alpinia galanga and Alpinia oxyphylla showed significant antiviral effects against BVDV without toxic effects …
New Method of DNA Isolation from Two Food Additives Suitable for Authentication in Polymerase Chain Reaction Assays
2005
Locust bean gum and guar gum are galactomannans used as additives (E 410 and E 412, respectively) in the food industry as stabilizing agents. Analytical discrimination between the two additives in gums and foods is now feasible by molecular techniques. However, only complex and time-consuming DNA isolation protocols are available to date. We have developed simple improved protocols to obtain enough DNA suitable for PCR amplification from a few milligrams of commercial E 410 and E 412 additives (containing more than 75% polysaccharides). The suspension of additives in water or 10 mM Tris-HCl, pH 8.5, efficiently recovers DNA suitable for authentication in PCR assays. However, the Tris method…
Wall mannoproteins in cells from colonial phenotypic variants of Candida albicans.
1990
Candida albicans ATCC 26555 switched at high frequency (10(-1) to 10(-3)) between several phenotypes identified by colony morphology on a defined mineral amino-acid-containing agar medium supplemented with arginine and zinc (LAZ medium). When cells taken from colonies exhibiting distinct morphologies were plated directly onto LAZ agar, spontaneous conversion to all the variant phenotypes occurred at combined frequencies of 2.1 x 10(-1) to 9.5 x 10(-3). However, when cells taken from the different colonial phenotypes were plated directly onto an undefined medium (yeast extract/peptone/dextrose; YPD medium), or first incubated in liquid YPD medium and then cloned on YPD agar, all colonies obs…
Characterisation of Pythium paroecandrum and its antagonism towards Botrytis cinerea, the causative agent of grey mould disease of grape.
2004
Pythium paroecandrum (B-30), an oomycete, was isolated from soil samples taken from a wheat field in Genlis in the Burgundy region of France and was found to check the growth and development of Botrytis cinerea, a serious grapevine pathogen. The oomycete is a fast-growing organism, living on vegetable debris, and can be recognised by its catenulate hyphal swellings, catenulate oogonia, and monoclinous antheridia. When grown together with B. cinerea, the causal agent of the grey mould disease of the grapevine, P. paroecandrum shows a pronounced antagonism and suppresses its growth and its aptitude to provoke the grey mould symptoms. Morphological features of this oomycete, its antagonism to …
A new mycoparasite, Pythium lycopersicum, isolated in Isparta, Turkey: morphology, molecular characteristics, and its antagonism with phytopathogenic…
2008
Pythium lycopersicum sp. nov. has been isolated from soil samples taken in an agricultural land in the Isparta region of Southern Turkey. This oomycete is characterized by its contiguous sporangia having globose to elongated elements linked with hyphal filaments, ornamented oogonia, and monoclinous antheridia with large antheridial cells. The oomycete is reminiscent of Pythium ornamentatum described by the corresponding author in 1987 from soil samples taken in Algeria. Sequence analyses of the internal transcribed spacer (ITS) regions of rRNA show a close relationship with Pythium oligandrum and other mycoparasites possessing ornamented oogonia. Morphological and molecular features of this…
La place des femmes dans le football : entre inégalités et discriminations
2018
National audience; Mes travaux portent entre autres sur la féminisation du football et les inégalités qui y subsistent. J’interroge notamment la place prise ou laissée aux femmes dans cet espace encore fortement dominé par les hommes. Mon intervention portera donc sur les formes « subtiles » d’inégalités que vivent les footballeuses en France, malgré un engouement sans précédent de la pratique et une exposition médiatique désormais considérable. La subtilité de ces inégalités reposent notamment la question de la définition ou de la qualification de la notion d’inégalité versus discrimination.
Detecting Asset Misappropriation: Forensic Accounting
2021
The main task of the investigation of asset misappropriation is the correct classification of a crime: identification of the fact of misappropriation and determination of the amount of misappropriated assets. Specificity of asset diversity, asset accounting requirements, and a wide range of misappropriation opportunities require specialised knowledge in accounting and economics that investigators often lack. The aim of the study is to increase the knowledge of investigators in forensic accounting in order to increase effectiveness of investigations in detecting asset misappropriation. In this article, the authors, Latvian and Lithuanian accounting experts, talk about typologies of asset mis…
Science and law in the time of cholera: the mystery of the biscuits in Torroja (1865)
2018
By focussing on a case of collective poisoning in 1865, four features of forensic cultures are analysed: technologies for detection, authorized voices, regulations in action and the predominant social anxieties. Local newspapers and archival documents kept in the medical academies of Barcelona and Madrid are analysed. The analysis shows the tensions between various types of proof employed in legal medicine and the ambiguities between epidemic diseases and poisoning accidents. In the first section, I review the fears caused by the cholera epidemic in 1865, which was the first explanation of the accident. The changes of popular perception are also discussed by analysing contemporary newspaper…
Dix ans d'archéologie forestière dans le Châtillonnais (Côte-d'Or) : enclos, habitats, parcellaires
2010
National audience; Ces recherches sur les ensembles de structures de pierre sous forêt sont mises en œuvre depuis dix ans et sont inté- grées depuis 2003 dans le P.C.R. ‘Vix et son Environnement', dirigé par C. Mordant, S. Wirth et B. Chaume. Les vestiges étudiés sont implantés dans deux milieux géographiques distincts mais contigus : le plateau calcaire recouvert par la forêt domaniale de Châtillon, et les rebords de la Digeanne et du Brevon qui entaillent ce plateau à l'est et au sud. La prospection présente ici des caractères particuliers liés au couvert forestier. Les relevés G.P.S. sont intégrés dans un S.I.G. et constituent la base de cette étude, dans un va et vient…
Pragmatično usmerjeni nauk o pravnem razlaganju
2012
Izhajajoč iz dinamičnega pristopa k razumevanju tvorbe pomena avtor v tej izvirni, za Revus napisani razpravi izgradi pragmatično usmerjeni nauk o pravnem razlaganju. Ta se odmika tako od formalističnih kot protiformalističnih pogledov, saj je v skladu z njim razlaganje hkrati »odkrivanje« nekaterih pomenskih ravni in »ustvarjanje« drugih. Pomen vsakršnih (tudi pravnih) izrazov ali stavkov je torej obravnavan kot nekaj stopnjevitega, oblikovanega na več ravneh. Obenem vključuje znotraj-jezikovno razsežnost (smisel) in razsežnost razmerja »jezik-svet« (nanosnik). Pomen nikoli ni proizveden hipoma in v celoti, ampak je oblikovan postopno, po korakih. Pri tem je za dokončno izoblikovanje pomen…
