Nanoparticles (NPS) are considered as a new generation of compounds to improve environmental remediation and biological processes. The aim of this study is to investigate the effect of iron NPS encapsulated in porous silica (SiO2) on the biphenyl biodegradation by Rhodococcus erythropolis T902.1 (RT902.1). The iron NPS (major iron oxide FexOy form) were dispersed in the porosity of a SiO2 support synthesized by sol-gel process. These Fe/SiO2 NPS offer a stimulating effect on the biodegradation rate of biphenyl, an organic pollutant that is very stable and water-insoluble. This positive impact of NPS on the microbial biodegradation was found to be dependent on the NPS concentration ranging from 10−6 M to 10−4 M. After 18 days of incubation the cultures containing NPS at a concentration of 10−4 M of iron improved RT902.1 growth and degraded 35% more biphenyl than those without NPS (positive control) or with the sole SiO2 particles. Though the microorganism could not interact directly with the insoluble iron NPS, the results show that about 10% and 35% of the initial 10−4 M iron NPS encapsulated in the SiO2 matrix would be incorporated inside or adsorbed on the cell surface respectively and 35% would be released in the supernatant. These results suggest that RT902.1 would produce siderophore-like molecules to attract iron from the porous silica matrix. [less ▲]

BACKGROUND: The auditory steady state response (ASSR) is a sustained electrical response of the brain to auditory stimuli delivered at fast rates (30-50 responses/s). The aim of this study was to evaluate the effect of 0.26-0.50% isoflurane on the ASSR and on consciousness, defined as responsiveness to verbal commands. METHODS: Ten volunteers (21-31 yr) participated. Isoflurane was administered at three stable, end-tidal concentrations: 0.26%, 0.38%, and 0.50%. The ASSR in response to 18,000 stimuli (500-Hz tonebursts, 10 ms, 82-dB, the right ear, 35-45 bursts/s) was recorded from the vertex with reference to the right mastoid. Recordings were made during baseline, at each isoflurane concentration, and during recovery. RESULTS: The mean (SD) ASSR amplitudes were 0.32 (0.23) microV during baseline, 0.24 (0.17) microV during 0.26% isoflurane, 0.09 (0.05) microV during 0.38% isoflurane, 0.04 (0.03) microV during 0.50% isoflurane, and 0.29 (0.33) microV during recovery. The amplitude during baseline and recovery was larger than during 0.38% and 0.50% isoflurane (P < 0.001). The amplitude at 0.26% was larger than at the other concentrations (P < 0.025). The logarithm of the ASSR amplitude was related linearly to the concentration of isoflurane (r = 0.85; P < 0.0001). The prediction probability (Pk) for loss of consciousness was 0.95 for both ASSR and measured isoflurane concentration. An ASSR amplitude < 0.07 microV was always associated with unconsciousness. CONCLUSIONS: The ASSR is attenuated in a concentration-dependent manner by isoflurane. Suppression of consciousness and maximal attenuation of ASSR occur in the same isoflurane concentration range. Profound attenuation of ASSR appears to reflect unconsciousness, defined as unresponsiveness to verbal commands. [less ▲]

The aim of this study is to correlate the creep parameters of aged Zn-Al samples with the microstructure developed during heat treatment, and to point out the practical interest of such microstructure modifications. Two different isothermal ageings were carried out at 100°C and at 250°C for different periods of times (from 30 min. to 8 weeks). During those ageings, complex precipitations occur. The decomposition of the initial supersaturated solid solution begins with a cellular reaction leading to cfc and hcp lamellar. The cfc phase decomposes into transition phases. The ageing temperature (100 or 250°C) influences the decomposition stages. Creep testson aged samples reveal the influence of the microstructure developed during the heat treatment at 100 or 250°C. An improvement of the creep properties by one order of magnitude can be observed when the sample exhibits the appropriate structure. [less ▲]

Ketoconazole (KET) is active to control dandruff and seborrhoeic dermatitis. Objective assessments comparing the 1% and 2% shampoo formulations are scant. This open, randomized parallel-group trial was carried out to differentiate the effectiveness of KET 1% and 2% in severe dandruff and seborrhoeic dermatitis. A total of 66 patients with severe dandruff or seborrhoeic dermatitis were randomized to each of the two groups. A 2-week run-in phase was followed by a 4-week treatment phase, in turn followed by a 4-week follow-up. The efficacy of treatments was evaluated by combining squamometry X, Malassezia spp. counts and clinical assessments. After 2 and 4 weeks of treatment, KET 2% was significantly superior over KET 1% (p < 0.001) for decreasing both in flakiness and Malassezia density from baseline. The same trend was observed in the mean change from baseline in the overall dandruff severity score. Only 6 mild adverse events were reported. During follow-up KET 2% showed a trend to fewer relapses than KET 1%. KET 2% had superior efficacy compared to KET 1% in the treatment of severe dandruff and scalp seborrhoeic dermatitis. Biometrological evaluations were correlated with the clinical improvements and therefore useful to incorporate in future dandruff studies. [less ▲]

Spray application efficiency depends on the pesticide application method as well as target properties. A wide range of drop impact angles exists during the spray application process because of drop trajectory and the variability of the leaf orientation. As the effect of impact angle on retention is still poorly documented, laboratory studies were conducted to highlight the effect of leaf orientation on drop impact outcomes. Measurements were performed with a high-speed camera coupled with a retro-LED lighting. Size and velocity of the drop were extracted by image analysis. Drop impact types were determined by the operator. Drops were produced with a flat-fan nozzle mounted on a movable ramp. Excised blackgrass [Alopecurus myosuroides HUDS. (ALOMY)] leaves were stretched between two parts of a U-shaped support. A surfactant (Break-Thru® S240) was sprayed to highlight the effect of mixture surface tension. The whole device was tilted from 0 to 90°. Relative volume proportions were computed within of an energy scale divided into 11 classes. These proportions have been weighted by an average volume distribution and the results were summed for all energy classes to obtain the total volume proportions for each impact outcomes and for all leaf angles. For distilled water (high surface tension) the increase of rebound proportion with the increase of drop impact angle is highlighted. For surfactant (lower surface tension), it results in an increase of drop fragmentation in Cassie-Baxter wetting regime. To be statistically representative, bigger drop samples should be used.

BACKGROUND: The positive effect of leukocyte- and platelet-rich fibrin (L-PRF) on osteogenesis has been widely described in vitro. However, clinical and preclinical studies are very little and controversial in demonstrating a significant beneficial effect of L-PRF in bone regeneration. PURPOSE: The goal of the present study was to compare the potential effect of L-PRF in a standardized model. MATERIALS AND METHODS: A total of 72 hemispheres were implanted on the calvaria of 18 rabbits and filled with three different space fillers: L-PRF, bovine hydroxyapatite (BHA), BHA + L-PRF, and an empty hemisphere was used as control. Six rabbits were sacrificed at three distinct time points: 1 week, 5 weeks, and 12 weeks. Histological and histomorphometrical analyses were carried out. RESULTS: At the early phase of bone regeneration (1 week), from a descriptive analysis, a higher proportion of connective tissue colonized the regeneration chamber in the two groups containing BHA particles. Nevertheless, no statistical differences were found within the four groups in terms of bone quantity and quality at each timepoint (p = .3623). CONCLUSIONS: According to the present study, L-PRF does not seem to provide any additional effect on the kinetics, quality, and quantity of bone in the present model of guided bone regeneration.

Microalgae contain valuable compounds that can be harnessed for industrial applications. Lignocellulose biomass is a plant material containing in abundance organic substances such as carbohydrates, phenolics, organic acids and other secondary compounds. As growth of microalgae on organic substances was confirmed during heterotrophic and mixotrophic cultivation, lignocellulose derived compounds can become a feedstock to cultivate microalgae and produce target compounds. In this review, different treatment methods to hydrolyse lignocellulose into organic substrates are presented first. Secondly, the effect of lignocellulosic hydrolysates, organic substances typically present in lignocellulosic hydrolysates, as well as minor co-products, on growth and accumulation of target compounds in microalgae cultures is described. Finally, the possibilities of using lignocellulose hydrolysates as a common feedstock for microalgae cultures are evaluated. [less ▲]

Sludge liming is largely used in the wastewater industry. This operation, at first realized to stabilize sludge, has also proved to enhance dewatering and to improve the resulting cakes texture. Nevertheless, almost nothing is known about the impact of lime addition on sludge drying behavior. As drying can be considered as a necessary step after mechanical dewatering, it is crucial to evaluate the influence of the sludge pre-treatments on their drying kinetics. This study shows that both pre- and post-liming exert a positive effect on sludge convective drying behavior. The negative impact of sludge destructuring by pumping is also established. [less ▲]
