This paper presents ash in Wallonia (Southern Belgium) and defines its silviculture in the respect of its characteristics (light demanding species, fast juvenile growth, site fertility demanding) and its wood market ( joinery wood, slicing). Two silvicultural ways are presented : “intensive silviculture” and “near-to-nature silviculture”, that are both based upon very similar guidelines (heavy and early thinnings in relation to objective-trees, short rotation, early harvesting) but differ by planting spacings and technical ways used to obtain a high quality butt log. At last, the influence of the proposed ash silviculture is evaluated from a biodiversity point of view, and some ways to preserve the floristic diversity dynamic are suggested. [less ▲]

Itraconazole is a broad spectrum antifungal agent of the bis-triazole class. The drug is an important option in the management of many human mycoses including various clinical presentations of aspergillosis. Indeed, the compound exhibits potent in vitro antifungal activity against Aspergillus spp. and shows variable fungicidal effect against the different species and strains. After amphotericin B, itraconazole has been the very first agent, and the first azole antifungal to have demonstrated clinical efficacy in aspergillosis. In vivo, the antifungal efficacy of itraconazole has been demonstrated in several types of aspergillosis both in immunocompetent and immunocompromised animal models. The drug administered in its oral or intravenous formulations displays non-linear plasma pharmacokinetics. Despite best current therapies, the outcome of invasive aspergillosis may remain dismal. Fungal cells can induce enormous damage on a background of immunosuppression. Medical help comes often too slow or is too weak. It will be a long time before the ideal strategy is found for an effective prophylaxis or for the optimal therapy of disseminated and invasive aspergillosis. In spite of this limitation, itraconazole has a definite chemotherapeutic effect in experimental aspergillosis. Non-comparative clinical data of itraconazole in the treatment of suspected or proven invasive aspergillosis indicate response rates at least similar and possibly superior to those of amphotericin B. Itraconazole has clearly improved the clinical outcome in some of the less immunosuppressed patients with invasive aspergillosis. The experience with itraconazole for induction therapy of invasive aspergillosis is more limited in profoundly neutropenic patients. Itraconazole has an important role for consolidation and maintenance therapy of patients with invasive aspegillosis. Itraconazole oral cyclodextrin solution is particularly suitable in these indications. Novel combination and sequential therapies involving itraconazole with other antifungals are promising. Itraconazole is usually well tolerated, but a potential for drug interactions exists, mediated through the cytochrome P450 3A4 system. This possibility should be considered when itraconazole is used as part of a multi-drug regimen. [less ▲]

Yeasts of the genus Malassezia are part of the normal skin biocenosis and are involved in a series of distinct skin disorders and specific dermatomycoses in man and animals. Several species are currently distinguished. Their relative in vitro susceptibility to antifungals appears different according to the species and to the nature and route of administration of the drug. Corneofungimetry is an ex vivo bioassay allowing to test the fungal response on human stratum corneum following oral intake of a given antifungal by volunteers. Two series of cyanoacrylate skin surface strippings (CSSS) were harvested from the volar forearm of 30 volunteers before and after a 2-week treatment with itraconazole 200 mg daily. They were coated by olive oil and inoculated with suspensions of seven different Malassezia spp. After a 1-week culture on CSSS, the amount of viable yeasts was assessed using neutral red staining assisted by computerized image analysis. Growth of the seven species was not similar on the CSSS from untreated stratum corneum. The ranking order from the most proliferative to the least was M. restricta, M. sympodialis, M. globosa, M. furfur, M. obtusa, M. slooffiae and M. pachydermatis. Their growth was abated to almost the same level after itraconazole treatment. It is concluded that in vivo treatment with itraconazole is highly active against all Malassezia spp. colonizing the human stratum corneum. [less ▲]

The short storage life of harvested cassava roots is an important constraint that limits the full potential of cassava as a commercial food crop in developing countries. We investigated the molecular changes during physiological deterioration of cassava root after harvesting using isobaric tags for relative and absolute quantification (iTRAQ) of proteins in soluble and non-soluble fractions prepared during a 96 h post-harvest time course. Combining bioinformatic approaches to reduce information redundancy for unsequenced or partially sequenced plant species, we established a comprehensive proteome map of the cassava root and identified quantitatively regulated proteins. Up-regulation of several key proteins confirmed that physiological deterioration of cassava root after harvesting is an active process, with 67 and 170 proteins, respectively, being up-regulated early and later after harvesting. This included regulated proteins that had not previously been associated with physiological deterioration after harvesting, such as linamarase, glutamic acid-rich protein, hydroxycinnamoyl transferase, glycine-rich RNA binding protein, beta-1,3-glucanase, pectin methylesterase, maturase K, dehydroascorbate reductase, allene oxide cyclase, and proteins involved in signal pathways. To confirm the regulation of these proteins, activity assays were performed for selected enzymes. Together, our results show that physiological deterioration after harvesting is a highly regulated complex process involving proteins that are potential candidates for biotechnology approaches to reduce such deterioration.

Podosphaera fusca is the main causal agent of cucurbit powdery mildew in Spain. Four Bacillus subtilis strains, UMAF6614, UMAF6619, UMAF6639, and UMAF8561, with proven ability to suppress the disease on melon in detached leaf and seedling assays, were subjected to further analyses to elucidate the mode of action involved in their biocontrol performance. Cell-free supernatants showed antifungal activities very close to those previously reported for vegetative cells. Identification of three lipopeptide antibiotics, surfactin, fengycin, and iturin A or bacillomycin, in butanolic extracts from cell-free culture filtrates of these B. subtilis strains pointed out that antibiosis could be a major factor involved in their biocontrol ability. The strong inhibitory effect of purified lipopeptide fractions corresponding to bacillomycin, fengycin, and iturin A on P fusca conidia germination, as well as the in situ detection of these lipopeptides in bacterial-treated melon leaves, provided interesting evidence of their putative involvement in the antagonistic activity. Those results were definitively supported by site-directed mutagenesis analysis, targeted to suppress the biosynthesis of the different lipopeptides. Taken together, our data have allowed us to conclude that the iturin and fengycin families of lipopeptides have a major role in the antagonism of B. subtilis toward P fusca. [less ▲]

IUE satellite UV spectra of RR Tel covering 1150-3200 A at high and low dispersion through both large and small apertures are reported, and a list of 431 lines is presented which gives measured wavelength, intensity, and full width at half maximum. Over three-quarters of the lines are identified, and a correlation is noted between line width and ionization energy. The lines identified, which include common species ionized from one to four times, are generally resonance, forbidden or semiforbidden lines but also include the recombination lines for C, O and Ne. Many Fe II lines are present. Forbidden line wavelengths are used to define intersystem separations of energy levels in some species. The continuum energy distribution yielded by low dispersion data is not due to a simple recombination of gaseous emission processes and a hot star or accretion disk, but the very high ratio of the energy in the lines to that in the continuum of 2.4 indicates that a high temperature source must be present.
