Controversy still exists concerning the proper daily dose of methadone to be used in opiate dependency treatment. Because it is admitted that serum methadone concentration may be significantly correlated with the amount of drug available at the receptor level, it could be interesting to predict the methadone daily doses necessary to reach such a serum concentration. The authors have attempted to correlate the serum methadone level with the daily intake, considering the metabolic activity of the patients. A poor correlation was found between methadone doses and methadone serum concentrations (r2 = 0.0409, p = 0.048). The test used to determine the metabolic activity of patients is the 6-OH cortisol/17-OH corticosteroids ratio in urine. This urinary 6-OH cortisol/17-OH corticosteroids ratio was tested because cortisol is metabolized through the same P450 cytochromes as methadone, namely cytochrome P450 3A4. This determination could be of interest because it could be tested before methadone administration to predict optimal doses. But when the authors tried to correlate the methadone serum concentration with the steroid ratio, they failed to find a significant correlation (r2 = 0.0046, N.S.), even when they took into account the daily doses (r2 = 0.0015, N.S.), most probably because of some limitations of the cortisol ratio.

The methanol dissociative adsorption on Pt(1 0 0) at low potentials in the hydrogen region is studied using nonlinear vibrational sum-frequency generation (SFG) spectroscopy. It is shown that adsorbed hydrogen atoms effectively block atop sites at the surface. In the hydrogen potential region, CO produced by the methanol dissociation adsorbs at step-edges and in bridge sites on terraces as shown by the characteristic stretching frequencies observed for adsorbed CO.

We developed an original method allowing long term culture (up to 20 month) of undifferentiated chicken PGCs, with good proliferation rates. We use a co-culture system: PGCs are cultivated in cell culture inserts, in the presence of irradiated Buffalo Rat Liver cells. According to our own experience, physical separation of PGCs and feeder cells limits the differentiation of PGCs. Our PGCs lines keep their original phenotype including their gonadal colonization ability. We also developed a novel cryopreservation method based on vitrification, in complement of a slow rate freezing. [less ▲]

The invention relates to a method for separating a first amount of liquid into a plurality of second amounts of liquid, the method comprising the steps of bringing the first amount of liquid (210) into contact with at least one first fibre (110) being arranged substantially vertical, allowing the first amount of liquid to drain of the first fibre, thereby forming a coating film on the fibre, allowing the coating film to decompose, thereby forming a plurality of second amounts of liquid (220), and allowing the second amounts of liquid to drain of the first fibre and being captured at a crossing point (130) being constituted by the first fibre and at least one second fibre (120) being arranged substantially perpendicular to the first fibre and touching the first fibre. Furthermore, the invention relates to an apparatus for separating a first amount of liquid into a plurality of second amounts of liquid. [less ▲]

The present invention is related to methods and kits (or devices) for the measurement of equine myeloperoxidase (MPO), a specific enzyme of equine neutrophils, either in total [first method], or specifically in its active form [second method]. Said methods and kits (or devices), used independently or in combination, find improved applications in the veterinary field and can be adapted for application in human health care. The concept of the second method is applicable to any other enzyme. [less ▲]

The correspondence problem is one of main topics in stereo vision that, despites being studied for many years, is still in progress. In this paper, we present a new method that computes the disparity map. Our method is local (i.e. only information gathered in the close neighborhood is used) and is based on image statistics. More specifically it combines multiple adaptive windows and local statistical measures in order to optimize the quality of the computation of disparity maps. As the size of windows is critical for local methods, we propose an algorithm that modifies the size of windows surrounding the pixel of interest to capture enough information in regions with low texture energy. This process is based on statistical measures (mean and horizontal/vertical average deviation) taken in the windows of the original stereo images. In the last section we show that our method performs very well compared to other existing local methods. [less ▲]
