Garlic has been used worldwide for centuries for its taste, but also for its health benefits. The therapeutic compounds are mostly organosulfurs, and can be formed when an enzyme, alliinase, gets in contact with its substrate, alliin. Both are separated in an entire cell, and react when the plant is damaged. The product of the enzymatic reaction, allicin, turns quickly into different molecules with potential beneficial effects. The way garlic is processed has a major influence on the released products. Indeed, an aqueous or oily medium, as far as the temperature, can emphasize the formation of specific compounds. Vinyldithiins are one of the active molecules, and are part of the garlic’s organoleptic properties. Their effects against obesity have been recently proven. This study aims to describe the conditions of vinyldithiins formation, as well as its extraction, purification and analyse. Vinyldithiins are mostly produced when garlic is crushed in edible oil, at low temperature. Extraction conditions (garlic/oil ratio, oil and garlic source, temperature and extraction time) were optimized. Analysis of the results were performed by HPLC.Finally, a purification process was set up. These results allow better knowledges on vinyldithiins formation that can be applied in garlic-based nutraceuticals. They might also lead to new uses of garlic in the production of highly valuable compounds. [less ▲]

Plusieurs arrêts de la Cour de Cassation ont admis que les frais et honoraires de l’avocat pouvaient constituer un poste du dommage réparable de la victime. Cette jurisprudence a été source de nombreuses controverses et a conduit le législateur a adopté la loi du 21 avril 2007 consacrée à la répétibilité des frais et honoraires d’avocats. Le mécanisme retenu par le Législateur consiste à allouer, au titre de la répétibilité, une indemnité de procédure, dont la définition a été ainsi modifiée (article 1022, al.1er du Code Judiciaire) et le montant revu à la hausse. Le premier chapitre consacré aux principes généraux a pour objet de tracer les principes qui s’appliquent, en matière de répétibilité des frais et honoraires d’avocats, pour toutes les procédures civiles et pénales. Ces principes connaissent toutefois des exceptions, modalisations et applications différentes dans ce dernier domaine. Le deuxième chapitre de l’ouvrage est donc consacré aux spécificités de la répétibilité en matière pénale. Le troisième chapitre traite de quelques procédures particulières, notamment en droit public et administratif ainsi que la procédure en cassation. Quant au quatrième chapitre, celui-ci aborde la problématique de l’application dans le temps de la loi. [less ▲]

Pourquoi retourner à Brentano?

What, if anything, can we expect to gain in adopting a Brentanian approach to the mind? Within the field of contemporary philosophy of mind, two distinct motivations are usually put forward in order to justify something like a return to Brentano: His intentionality thesis and his theory of inner perception. I suggest (a) that these two motivations are much more controversial than it is usually believed and (b) that there nevertheless exists another, more convincing reason for going back to Brentano, namely, his theory of mental analysis.

L'épargne sanguine: un enjeu actuel

In view of the demographic evolution, the progress of quality requirements and the shortage of donors, a deficiency of blood components is to be feared in the coming years.. This implies the development of a blood conservation strategy, the revision of transfusion practices and the implementation of preventive measures to limit transfusion requirements. Each department caring for patients at high transfusion risk should assess and rationalize its transfusion practices in a structured multidisciplinary way [less ▲]

Viandes bovines à longue durée de conservation conditionnées sous vide : isolement et caractérisation de souches de Carnobacterium

The lactic acid bacteria Carnobacterium divergens and Carnobacterium maltaromaticum are often associated to meat and meat products and may be used as a protective culture, improving the microbial stability and the safety of these products. In this context, the aim of this study was to isolate and characterize Carnobacterium from long shelf-life vacuum-packed beef. LAB counts after culture at +22°C remained below 2.0 log UFC/cm², even at the end of shelf life. On the other hand, the ecosystem evaluation performed by metagenomics revealed the predominance of Carnobacterium and Lactobacillus on the samples. After spreading of a peptone water suspension obtained from the samples on PCA, pure isolates were collected and identified by API 50 CHL galleries. Seventy-eight % of isolates were C. maltaromaticum, 3 % C. divergens and 19 % could not be identified. The next step of this work will consist in performing a genotypic and functional characterization of these Carnobacterium isolates. [less ▲]

Hybrid Lens for Solar Concentration: Optimization of the Multilayer Diffractive Lens

Poster (2012, November 12)

Manufacture process degrades the ideal shape of multilayer diffractive lens due to draft angle, half radius tool and slope error. We show some shape improvements using an extended scalar theory.
