Plant rennets hold an important position amongst various coagulants used in cheese technology. The selection of a suitable plant coagulant is important due to the increasing global demands of cheese alongside reduced supply of calf rennet. Thus, a literature synthesis is presented to investigate recent achievements on their functional properties and enzymatic role in cheese making. Efforts have also been done to compare certain rheological and sensory properties of final products, arising from some plant and animal based rennets. In fact, some coagulants such as actinidin or dubiumin produce cheeses with sensory qualities similar to those produced by animal rennet. Others, like ginger, cucumisin or hieronymain proteases contribute to develop very different textures and flavors, due to excessive proteolytic activity and production of bitter peptides. For milk-clotting enzymes with high non-specific action, several improvement strategies have been developed to produce cheeses with sensory properties close to those of animal rennet. For example, the mixture of coagulants (cardosins/chymosin), the selection of appropriate milk or its ultrafiltration, as well as the increase of salting time of cheese during ripening could be efficient ways to improve texture and reduce bitterness. Concerning cheeses with high yield loss, the whey could be used for a traditional production of whey cheese. To conclude, the selection of appropriate plant rennet with high MCA/PA ratio and the optimization of all coagulation parameters play a central role in manufacturing cheese with superior rheological and sensory properties.

Dans le dernier quart du XVIe siècle, Philippe II d’Espagne est à la tête de l’ensemble territorial le plus puissant d’Europe. Fils préféré de l’Église romaine et souverain reconnu d’une grande partie de l’Italie, il exerce une influence considérable sur la papauté à travers l’action de son ambassadeur espagnol résidant près le Saint-Siège. Ce dernier a pour tâche d’étendre le réseau des alliés au sein de la Curie. Il chapeaute aussi les différents services diplomatiques et ecclésiastiques des États de la monarchie présents dans la cité des papes . Si elle conserve une certaine autonomie, la légation des Pays-Bas et de la Franche-Comté près le Saint-Siège – conduite par l’agent Laurent du Blioul de 1573 à 1598 – est également soumise à la volonté de cet envoyé. Ce n’est d’ailleurs pas un hasard si l’étude de la légation à l’époque du règne de Philippe II a peu passionné les historiens . Effacée derrière la puissance de l’ambassadeur espagnol, celle-ci semble être un piètre avatar des services ecclésiastiques et diplomatiques dépêchés à Rome par les ducs de Bourgogne , Philippe le Beau ou les archiducs Albert et Isabelle . Or, si, aux temps de Laurent du Blioul, la légation, considérée en tant qu’actrice isolée dans le paysage romain, joue un rôle modeste qui se cantonne au suivi des affaires ecclésiastiques provenant des Pays-Bas et de la Franche-Comté, il faut envisager qu’elle fait partie intégrante d’une toile religieuse, diplomatique, sociale et politique plus vaste tissée à Rome par le roi Philippe II et ses agents. Dépassant les seuls intérêts des Pays-Bas, l’étude de cette institution conduit à appréhender tout un pan de la stratégie politique habsbourgeoise. L’imbrication de la légation dans le théâtre diplomatique espagnol à Rome a deux facettes : si, d’une part, elle limite les prérogatives institutionnelles de l’agent du Blioul, d’autre part, elle favorise régulièrement l’efficacité de son action.

In this paper we study the Christian symbols, as the cross (), the staurogramm (⳨, and its variant with an appendage ), the chi-rho sign (⳩), and the crux ansata (☥) in Greek literary and documentary papyri. The first part is dedicated to the study of the form and the origin of the Christian symbols, on the ground of both the oldest papyri which bear them and the literary sources about them. In the second part we analyze their disposition in the papyri and in relation to the texts they bear. Finally, in the third part, the data studied before lead to identifying the functions of the Christian symbols in the papyri. [less ▲]

En 1928, des étudiants de l’Académie des Beaux-Arts de Liège fondent la revue d’architecture et d’urbanisme L’Équerre. S’inscrivant bien que tardivement dans la continuité des avant-gardes internationales, le mensuel revendique une vision transversale de l’architecture où la réflexion plastique occupe une place centrale. Dès le départ, elle s’associe à Anthologie, revue imprégnée des théories futuristes et qui diffuse les artistes de l’avant-garde locale. D’abord par le biais de l’édition et des expositions, plasticiens et architectes travaillent ensuite ensemble dans le cadre de projets ambitieux financés par les pouvoirs publics. Cette contribution revient aux racines de cette collaboration en définissant les liens théoriques ou personnels unissant les deux revues. En se concentrant sur les infrastructures publiques, elle comment les artistes et les architectes ont répondu ensemble aux exigences concrètes de la commande en les replaçant dans le contexte social, politique et économique d’une ville belge de seconde importance à la veille de la Seconde Guerre mondiale.

This manuscript presents the work carried out within the European Project RENAISSANCE-ITN, which was dedicated to the development of innovative polyelectrolytes for energy and environmental applications. Within the project different types of innovative polyelectrolytes were synthesized such as poly(ionic liquid)s coming from renewable or natural ions, thiazolium cations, cathechol functionalities or from a new generation of cheap deep-eutectic monomers. Further, macromolecular architectures such as new poly(ionic liquid) block copolymers and new (semi)conducting polymer/polyelectrolyte complexes were also developed. As the final goal, the application of these innovative polymers in energy and environment was investigated. Important advances in energy storage technologies included the development of new carbonaceous materials, new lignin/conducting polymer biopolymer electrodes, new iongels and single-ion conducting polymer electrolytes for supercapacitors and batteries and new poly(ionic liquid) binders for batteries. On the other hand, the use of the innovative polyelectrolytes into sustainable environmental technologies led to the development of new liquid and dry water, new materials for water cleaning technologies such as floculants, oil absorbers, new recyclable organocatalysts platform and multifunctional polymer coatings with antifouling and antimicrobial properties. All in all this article demonstrates the potential of the poly(ionic liquid)s for high-value applications in Energy & Enviromental areas. [less ▲]

Low-melting berry wax (BEW) has proven to be a good oil gelator with a positive contribution to the consistency and flexibility of the structured oil. Nevertheless, the properties of BEWand the corresponding oleogel have not yet been investigated in-depth. In this research, the difference in crystallization and gelling behavior between sunflower wax (SW), a high melting wax, and BEW, a low-melting wax, in rice bran oil (RBO) was investigated. The difference in melting and crystallization temperatures can be explained by the different chemical composition (long-chain wax esters in SWand shortchain fatty acids in BEW). The heterogeneity in crystal habits (unidirectional platelets versus microcrystalline particles) and polymorphism (orthorhombic versus hexagonal) are responsible for the varying gel strength and hardness of the respective SWand BEW-oleogels. The microcrystalline BEW particles aligned and reorganized during 1-month storage at 5 °C, which leaded to an increase in the gel strength and hardness of BEW-oleogel. The gelling property of SW-oleogel however did not significantly differ after 4 weeks at 5 °C, despite of the appearance of spherulitic crystalline clusters. The changes in the physical properties of wax-based oleogels during storage time were further explored using differential scanning calorimetry, polarized light microscope, powder X-ray diffraction and rheology.

Common clay deposits from five localities in Foumban (West Cameroon) were investigated for their morphological, mineralogical and geochemical properties to determine their potential source rocks and suitability in ceramic product. The analytical results were obtained by X-ray diffraction, X-ray fluorescence spectrometry, Thermogravimetric Analysis, Scanning Electron Microscopy, and Fourier Transform Infrared Spectrometry. Morphologically, an homogeneous clayey layer was found in the upper part of a laterite cover on interfluves, and a clayey heterogeneous hydromorphic material in valleys. They are minerallogically composed of kaolinite (25-84%), illite (0-18%), smectite (0- 31%), and chlorite (0-8 %), associated with quartz (2-44 %), K-feldspars (0-27 %.), plagioclase (0-26%), goethite; (0-9%) with traces of rutile and hematite (≤5 %). The geochemical analysis shows a 115 relative large amount of SiO2 (45-71%), Al2O3 (14-31%), and low Fe2O3 (up to 11 %) suggesting weathering of mainly granitic and rhyolitic parent rocks. Most studied clays could be applied to building ceramic product such as bricks (refractory or not) and tiles. Illite may promote the glassy phase responsible for the densification of the final product. In addition, the relatively high proportion of alkali elements (K2O + Na2O, 6-8%) in some samples from Marom, Koutaba and is responsible for low firing temperature. However the presence of smectite (up to 5 %) limits the application of some Koutaba and Marom clays for ceramic building. The high Fe2O3 contents (> 8 %) in some Bangourain clays implied some pretreatment. [less ▲]

Malgré les stratégies de prévention actuelles, la maladie du greffon contre l’hôte (greffe-versus-hôte, GVH) aiguë (GVHa) reste une complication sévère et fréquente de l’allogreffe de cellules souches hématopoïétiques. Bien que la physiopathologie de celle-ci ne reste que partiellement élucidée à ce jour, il est classiquement admis que les lymphocytes T (LT) jouent un rôle important dans son processus biologique. Les progrès récents de l’immunologie des LT dans la GVHa ont permis de diversifier les pistes visant à prévenir la survenue de cette complication post-greffe. Plusieurs approches sont en cours d’exploration dans des essais cliniques avec des résultats encourageant tels que la manipulation ex vivo des LT avant leur transfert chez le patient afin de leur faire exprimer des gènes suicide, l’élimination in vivo des LT proliférant directement après la greffe, l’inhibition de l’activation des LT en interférant avec les voies de signalisation en aval du TCR ou celles induites par les cytokines, l’induction de l’anergie des LT en bloquant les signaux de costimulation, le blocage de l’adressage des LT vers les organes lymphoïdes secondaires et les tissus cibles, la promotion de l’immunotolérance par la perfusion de lymphocytes T régulateurs ou par l’utilisation d’agents favorisant leur différenciation et leurs fonctions in vivo et la modulation de l’expression génique des cellules immunitaires par des modulateurs épigénétiques. Outre la prévention de la GVHa, le défi des nouvelles stratégies consiste également à ne pas compromettre l’effet bénéfique de la greffe contre la tumeur ni la reconstitution des défenses anti-infectieuses.

Surface-enhanced Raman spectroscopy (SERS) is a sensitive analytical tool used in the pharmaceutical field in recent years. SERS keeps all the advantages of classical Raman spectroscopy while being is more sensitive allowing its use for the detection and the quantification of low-dose substances contained in pharmaceutical samples. However, the analytical performance of SERS is limited due to the difficulty to implement a quantitative methodology correctly validated. Nevertheless, some studies reported the development of SERS quantitative methods especially in pharmaceutical approaches. In this context, this review presents the main concepts of the SERS technique. The different steps that need to be applied to develop a SERS quantitative method are also deeply described. The last part of the present manuscript gives a critical overview of the different SERS pharmaceutical applications that were developed for a non-exhaustive list of pharmaceutical compounds with the aim to highlights the validation criteria for each application.
