En Région wallonne, des sols agricoles situés à proximité d’anciens sites de traitements de minerais ont été impactés par des retombées atmosphériques contaminées en cadmium (Cd), plomb (Pb) et zinc (Zn). Afin d’étudier l’impact de ces contaminations sur la qualité des productions agricoles, une étude du transfert en Cd et Zn du sol vers l’orge de printemps (Hordeum vulgare L.) a été réalisée sur une de ces zones contaminées. Dix-huit prélèvements d’orges ont été effectués en zone contaminée, 10 autres en zone témoin non contaminée et chacun d’eux a été subdivisé en trois sous-échantillons (ti

La station d’épuration par boues activées de Nador génère de grandes quantités de boues qui posent un sérieux problème environnemental. Ces boues sont stockées à côté de la lagune de Nador, sans aucune mesure assurant leur innocuité à l’environnement. Pendant la période pluvieuse, les eaux de pluies s’infiltrent à l’intérieur des déchets en se chargeant de leurs composés minéraux et organiques générant ainsi un lixiviat. Notre étude vise à caractériser le lixiviat des stocks de boues et à approcher expérimentalement via un test de percolation le risque du transfert possible des contaminants is

Novel azole adducts were produced by reaction of azoles and 2-acyloxyaryl aldehydes. The mechanism of the reaction involves attack by the azole at the carbonyl group and transfer of the acyl group to form an azole-substituted benzylic ester. 2-Acyloxyaryl ketones did not undergo an analogous reaction. An aminal was formed rather than an azole-substituted benzylic carbonate when a 2-aryl aldehyde carbonate was used as substrate.

ABSTRACT Candida albicans azole-resistant clinical isolates overexpressing the CDR1 and CDR2 genes (multidrug transporters) also overexpress the PDR16 gene (phosphatidylinositol transfer protein). We show here that the PDR16 promoter displays higher transcriptional activity following integration in an azole-resistant isolate than in the matched azole-susceptible one. Thus, the upregulation of PDR16 in the resistant strain results from a mutation acting in trans.

ABSTRACT The development of azole resistance in Candida albicansis most problematic in patients with AIDS who receive long courses of drug for therapy or prevention of oral candidiasis.

All strains of C. gattii manifested heteroresistance, with LHFs that ranged between 4 μg/ml and 32 μg/ml. A considerably higher proportion of the C. gattii strains (86%) than Cryptococcus neoformans strains (46%) exhibited LHFs that were ≥16 μg/ml.

Glycosylphosphatidyl inositol (GPI)-anchored proteins in Candida albicans are responsible for a vast range of functions, and deletions in certain GPI-anchored proteins severely reduce adhesion and virulence of this organism. In addition, completely modified GPIs are necessary for virulence. GPI anchor biosynthesis is essential for viability and starts with the transfer of N-acetylglucosamine to phosphatidylinositol. This step is catalysed by a multi-subunit complex, GPI–N-acetylglucosaminyltransferase (GPI–GnT). In this, the first report to our knowledge on a subunit of the Candida GPI–GnT com

Streszczenie:

High corrosion inhibition efficiency of the 2-mercaptobenzimidazole (MBI) molecule for copper in different aqueous solutions is well established. We propose a first principle DFT study of the surface chemistry of the adsorption of MBI on preoxidized Cu(111). For both thione (MBIH) and thiolate (MBI<sup>◦</sup>) species, the formation of a full monolayer (ML) is favored over low coverage adsorption. At the ML coverage, the molecules adopt a perpendicular orientation with respect to the surface. MBI<sup>◦</sup> interaction with the surface is stronger than MBIH one. MBIH and MBI<sup>◦</sup> bond

Redox flow batteries (RFBs) are rapidly gaining traction among large-scale storage solutions for intermittent renewable energy. Given the anticipated global scale of this technology, there is an intensive ongoing search for active electrolyte species containing all earth-abundant elements. Potential RFB actives must satisfy several criteria to maximize battery performance, namely, high solubility in the RFB solvent, optimum reduction potential, and chemical stability in all redox states. Given the near infinite possible molecular combinations of the primary atoms C, H, N, O, S, and Fe, computa
