Leaves of Mangifera Indica (MI, mango leaves) and Manihot Utilissima (MU, cassava leaves) are available in tropical regions and are the most accessible vegetal wastes of Kinshasa, capital of Democratic Republic of Congo. These wastes are not suitably managed and are not rationally valorized. They are abandoned in full air, on the soil and in the rivers. They thus pollute environment. By contrast, they can be recuperated and treated in order to produce methane (energy source), organic fertilizer and clean up the environment simultaneously. The main objective of this study was to investigate methane production from MI and MU leaves by BMP tests at 30 °C. The yields achieved from the anaerobic digestion of up to 61.3 g raw matter in 1 l medium were 0.001 l/g and 0.100 l CH4/g volatile solids of MI and MU leaves respectively. The yield of MU leaves was in the range mentioned in the literature for other leaves because of a poor presence of bioactive substrates, and low C/N ratio. By contrast, the methane yield from MI leaves was almost nil suggesting some metabolism inhibition because of their rich composition in carbon and bioactive substrates. Whereas classical acidogenesis and acetogenesis were recorded. [less ▲]

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.

tWe describe the quantitative synthesis of a Schiff base derived from methionine and salicylaldehyde(SMSB) which displayed turn-on selective fluorescent chemo-sensing properties for Zn2+in bufferedCH3CN/H2O (1:1) solution. In physiological pH (7.2 buffered) SMSB exhibited high selectivity and sen-sitivity toward Zn2+over the other selected metal ions. Upon the addition of Zn2+33 folds of emissionenhancement was observed in SMSB and limit of detection (CL) for Zn2+was found to be 5.0 × 10−7M. Thisbinding phenomenon was studied by1H NMR and HR-MS analysis. Mass spectrometry analysis revealedthat SMSB interacts with Zn2+and form a 1:1 complex, also confirmed by Job’s plot. This probe wascompletely retrieved by adding EDTANa2solution, exhibited a fluorescent quenching effect by removingZn2+from the sensor. SMSB was observed to have a good tolerance for fluorescence detection of Zn2+in pH range 6–10. Furthermore it is successfully investigated for living cells imaging using MCF-7 cells.Combine experimental results indicated SMSB to be a useful and powerful chemosensing probe for Zn2+in water as well as in living cells.

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 ▲]

A method for synthesizing compds. labeled with any isotopic element is disclosed. The method comprises the steps of prepg. the labeling agent, labeling a precursor in the form of a protected substrate, pre-​purifying and deprotecting same, and forming a final soln. of the resulting compd. The deprotection step, in which the labeled precursor is converted into a labeled compd., is performed directly on a solid medium in a column or a cartridge. A device for synthesizing the labeled compd. according to said method is also disclosed. Thus, 2-​[18F]​fluoro-​2-​deoxy-​D-​glucose and 1,​3,​4,​6-​tetra-​O-​acetyl-​2-​trifluoromethanesulfonyl-​β-​D-​mannopyranose were prepd. [less ▲]
