The antimycotic activity of a new parenteral solution containing miconazole was compared to that of a marketed solution (Daktarin IV solution). This solution has been withdrawn from the belgian market probably because of the toxic effects related to the presence of polyoxyl 35 castor oil. We propose a new formulation containing 10 mg of miconazole per ml (as the marketed solution), in combination with HP-beta cyclodextrin and lactic acid. The MIC of these two solutions were determined by broth microdilution method (following the NCCLS guidelines) against 15 yeasts and 16 filamentous fungi isolates. This study showed that MIC obtained with these two solutions are not significantly different. In vitro, the cyclodextrin solution has the same antimycotic activity as the Daktarin IV solution and can be proposed as a safe and effective parenteral solution to replace the previous surfactant solution.

The purpose of this work was to study electrocardiographic features of double-muscled beef cattle. Electrocardiograms were recorded on one to six occasions from each of a group of 18 conventional calves of the Friesian breed and 29 double-muscled calves of the Belgian White and Blue breed. Ages of the calves at the times of examination ranged from eight to 348 days. The Holmes semi-orthogonal lead system was used. The waves and interval durations and the tridimensional P, QRS, and T modal vector orientation and amplitude were calculated. The magnitude of the cardiac vectors was significantly lower and the ventricular waves and QT interval duration significantly shorter in the double-muscled than in the conventional calves. The P modal vector pointed significantly less downwards and the QRS modal vector pointed significantly more forwards and less up- and rightwards in the Belgian White and Blue, than in the Friesian group. Most of the observed differences might be a consequence of the bodily, and more specifically the thoracic, conformation of the former calves. However, the lower cardiac vector magnitude and shorter wave and interval durations might also reflect lower cardiac mass in the double-muscled subjects. [less ▲]

The condensation of chicken erythrocyte (CE) and calf thymus (CT) chromatins upon addition of di- and multivalent cations has been studied using turbidity, precipitation and electric dichroism measurements. For all the cations investigated (Mg2+, Tb3+, Co(NH3)6(3+), spermidine Spd2+ and spermine Sp4+) condensation of CE chromatin occurred before the onset of aggregation, while aggregation of CT chromatin started before condensation with all cations except Mg2+ and Tb3+. Precipitation of CE chromatin required lower di- and multivalent cations concentrations than CT chromatin. The electric dichroism data for both chromatins, at low ionic strength in the absence of di- or multivalent cations, indicated that the nucleoprotein molecules were not totally decondensed but that a "precondensed" state was already present. A positive electric dichroism was observed for the most condensed chromatin fibers, in agreement with the "cross-linker" models. Tb3+ led to less compact condensed particles as judged from the electric dichroism observations, but electron microscopy revealed that "30 nm fibers" were formed. Very little aggregation was produced by Tb3+. On the contrary, spermine produced very large networks of condensed molecules, but large spheroidal particles were also observed. The condensation of CE chromatin happened without changes of solution conductivity upon cation salt addition, regardless of the condensing cation, indicating a cooperative uptake of the ions during this process.

This manuscript compares the modifications induced by the heat-moisture treatment of native starch (HMT) and by the hot-air drying of corn on wet-milled starch granules. High temperatures applied during both corn drying and HMT reduced the swelling capacity of granules, increased the starch gelatinization temperatures and decreased their residual enthalpy. Pasting behaviour of pre-treated starch showed a decrease of peak and breakdown viscosity when corn drying and HMT temperatures increased. Microscopic analysis showed that after hydrothermal treatment, starch granules extracted from corn dried at lower temperature swell more significantly than those extracted from corn dried at higher temperature. All these changes suggest the occurring of structural modifications within starch granules during high-temperature pre-treatments. At similar temperatures and initial moisture contents, HMT affected the physicochemical and functional properties of cornstarch more dramatically than hot-air drying. Differences induced by these two treatments were attributed to the availability of water around granules during these two pre-treatment procedures. [less ▲]

Impetigo is a superficial bacterial infection of the skin. It is a contagious condition particularly affecting children. In many instances, a topical antibacterial treatment is recommended to clear the disease. Topical antibiotics and antiseptics can be used, but the risk for antibiotic-induced bacterial resistance of the community-acquired type has been pointed out. The present study was undertaken as a randomized intraindividual comparative trial between fusidic acid (FA) cream and povidone iodine (PVP-I) gel in 40 children suffering from impetigo. Cultures revealed Staphylococcus aureus in the vast majority of the cases. The lesions present on each upper limb were treated twice daily with one or the other test formulation. Clinical assessments were performed twice weekly until cure. After one week, cure was obtained in 57.5% of the PVP-I-treated limbs compared to 32.5% of the FA-treated limbs. At the end of treatment cure was obtained first on the PVP-I treated sites in 67.5% of cases compared to 15% on the FA-treated sites. Clinical cure occurred simultaneously on both test sites in 17.5% of cases. In conclusion, PVP-I provided faster clinical cure than FA. Considering the treatment cost, the raising community-acquired staphylococci resistance to FA, and the results of the present study, PVP-I gel appears superior to FA cream in childhood impetigo.

A typology of the main channel of the river Rhine according to its aquatic bryophyte and vascular hydrophyte assemblages is presented. The aquatic bryophytes are especially abundant in the main channel, having found stable, rocky habitats with variable water levels in the regulated river, and segregate longitudinally along a gradient of water quality. Conversely, the vascular hydrophytes are restricted to side channels with constant discharges and silt deposits, and segregate laterally along a gradient of connectivity with the main river. The hydrophytes have been affected by water eutrophication which became obvious in the 1960s-1970s. The oligotrophic groundwater-fed side-channels disconnected since the river canalization consequently include a relic reference flora. Important hydraulic works are currently in progress in order to protect the areas located downstream from the canalized Rhine from flooding by retaining the river waters in lateral systems during the discharge peaks and to recreate a functional alluvial floodplain by reconnecting the disconnected side-channels to the main river. The floodpulse caused by the suddent input of surface water in the disconnected brooks will probably wash out most of the hydrophytes and it is very likely that the rare species with their low recolonization strategies will disappear in these conditions. It is highly desirable to preserve from flooding the last oligotrophic brooks with their original hydrophyte assemblages. Those brooks which show a tendency to silt up can be re-dynamized by ecological engineering without disturbing the flowing drains of the watertable. In areas (including flowing drains of the watertable) that have already been designated for flood retention, the hydraulic works should allow, as far as possible, the preservation of the flowing oligotrophy streams by only permitting the input of surface water in the silted-up brooks. The disconnected side-channels could then continue their role as refugia from where the main channel, whose water quality has been improving for a decade, could be recolonized by its primary flora.

This study presents the life cycle assessment (LCA) of two buildings similar in dimensions, orientations, climate and purpose but designed for Belgium using two different construction systems: traditional masonry made of concrete blocks, insulation and ceramic bricks and light gauge steel framing as the load carrying component. The comparison between the LCA focuses on the CO2 emission equivalent for each building’s life cycle. After a short sensitivity analysis, the results of the assessment are compared against each other and the conclusions are presented. [less ▲]
