Following the patrimonialization process of the Mediterranean diet, some gastronomies found themselves involved within a common framework of food traditions. Some regional practices, indicated as representative of national food cultures, were chosen to illustrate a shared heritage that historically took a shape around the Mediterranean sea. This heritage, still concretely performed, needed to be stated and preserved against the globalization of food practices. Institutional and political dynamics, occurring on a transnational level, triggered this process, which is nevertheless not detached from the communities involved. Common people played a fundamental role not only in promoting the patrimonialization process itself, but above all in concretely perpetuating some traditions and in spreading them in the contemporary world. In particular, some different cultural groups that found themselves living a common territory and social context thanks to migration, began dialoguing about their own food traditions, starting from some shared elements. As a consequence, some gastronomies interact through people’s practices and define in relation one to the other. This is the case, among others, of Moroccan and Italian cuisine. Throughout a doctoral research conducted within a group of Moroccan women living in the North of Italy, I collected an amount of ethnographic materials showing how social encounters developed through food. The influence of the patrimonialization process on these encounters made people try to find similarities among different traditional practices or to describe some ways of reinterpreting them in reason of the new context. My presentation will focus on these dynamics, thus proving that the Intangible Cultural Heritage is indeed grounded on materiality, that is, in this case, the concrete performance of food practices and their pragmatic effects on relations among humans.

Purified chitin-glucan complex (CGCpure) was extracted from Komagataella pastoris biomass using a hot alkaline treatment, followed by neutralization and repeated washing with deionised water. The co-polymer thus obtained had a glucan:chitin molar ratio of 75:25 and low protein and inorganic salts contents (3.0 and 0.9 wt%, respectively). CGCpure had an average molecular weight of 4.9 × 105 Da with a polydispersity index of 1.7, and a crystallinity index of 50%. Solid-state NMR provided structural insight at the co-polymer. X-ray diffraction and FTIR analysis suggest that CGCpure has b-chitin in its structure. CGCpure presented an endothermic decomposition peak at 315 oC, assigned to the degradation of the saccharide structures. This study revealed that K. pastoris CGC has properties similar to other chitinous biopolymers and may represent an attractive alternative to crustacean chitin derived-products, being a reliable raw material for the development of new/improved pharmaceutical, cosmetic or food products.

Radio observations are an effective tool to discover particle acceleration regions in colliding-wind binaries, through detection of synchrotron radiation; these regions are natural laboratories for the study of relativistic particles.Wind-collision region (WCR) models can reproduce the radio continuum spectra of massive binaries that contain both thermal and non-thermal radio emission; however, key constraints for models come from high-resolution imaging. Only five WCRs have been resolved to date at radio frequencies at milliarcsec (mas) angular scales. The source HD93129A, prototype of the very few known O2 I stars, is a romising target for study: recently, a second massive, early-type star about 50 mas away was discovered, and a non-thermal radio source detected in the region. Preliminary long-baseline array data suggest that a significant fraction of the radio emission from the system comes from a putative WCR. We sought evidence that HD93129A is a massive binary system with colliding stellar winds that produce non-thermal radiation, through spatially resolved images of the radio emitting regions. Methods.We completed observations with the Australian Long Baseline Array (LBA) to resolve the system at mas angular resolutions and reduced archival Australia Telescope Compact Array (ATCA) data to derive the total radio emission. We also compiled optical astrometric data of the system in a homogeneous way. We reduced historical Hubble Space Telescope data and obtained absolute and relative astrometry with milliarcsec accuracy. The astrometric analysis leads us to conclude that the two stars in HD93129A form a gravitationally bound system. The LBA data reveal an extended arc-shaped non-thermal source between the two stars, indicative of a WCR. The wind momentum-rate ratio of the two stellar winds is estimated. The ATCA data show a point source with a change in flux level between 2003-4 and 2008-9, that is modeled with a non-thermal power-law spectrum with spectral indices of - 1:03 +/- 0:09 and -1:21 +/- 0:03 respectively. The mass-loss rates derived from the deduced thermal radio emission and from the characteristics of the WCR are consistent with estimates derived by other authors. [less ▲]

Secondary sexual traits may evolve under the antagonistic context of sexual and natural selection. In some polymorphic species, these traits are only expressed during the breeding period and are differently expressed in alternative phenotypes. However, it is unknown whether such phenotypes exhibit phenotypic plasticity of seasonal ornamentations in response to environmental pressures such as in the presence of fish (predation risk). This is an important question to understand the evolution of polyphenisms. We used facultative paedomorphosis in newts as a model system because it involves the coexistence of paedomorphs that retain gills in the adult stage with metamorphs that have undergone metamorphosis, but also because newts exhibit seasonal sexual traits. Our aim was therefore to determine the influence of fish on the development of seasonal ornamentation in the two phenotypes of the palmate newt (Lissotriton helveticus). During the entire newt breeding period, we assessed the importance of phenotype and fish presence with an information-theoretic approach. Our results showed that paedomorphs presented much less developed ornamentation than metamorphs and those ornamentations varied over time. Fish inhibited the development of sexual traits but differently between phenotypes: in contrast to metamorphs, paedomorphs lack the phenotypic plasticity of sexual traits to environmental risk. This study points out that internal and external parameters act in complex ways in the expression of seasonal sexual ornamentations and that similar environmental pressure can induce a contrasted evolution in alternative phenotypes.

Cette communication vise à étudier la participation des femmes migrantes marocaines à la vie sociale du « pays d’accueil » ; participation qui se réalise grâce aux activités de la vie quotidienne. En particulier, la performance publique des pratiques culinaires, observée dans une ville de la province de Milan, permet aux femmes considérées d’exercer une agency à l’intérieur des espaces institutionnellement concédés à l’expression des migrants. D’un côté, la consommation des « recettes de l’Autre » de la part de la population majoritaire détermine une incorporation de la diversité afin de la contrôler. De l’autre côté, la préparation de ces recettes consent aux migrantes d’exprimer leur subjectivité (individuelle et collective) de façon active et en présentant des aspects qui vont au-delà de la culture alimentaire. Une participation sociale fondée sur le partage de nourriture donne la possibilité aux femmes d’assumer un rôle actif dans la communauté locale, tout en affirmant ses propres spécificités. Des sujets tels que la liberté religieuse sont abordés, et certains droits peuvent être réclamés par des individus qui ont ainsi acquis une position politiquement importante au sein de la société locale.

The aim of this article is to discuss the diagnostic approach of an increased serum PTH concentration in a normocalcemic, normophosphatemicpatient. Detection of this biological presentation is frequent in routine practice all the more that PTH reference values established in vitamin Dreplete subjects with a normal renal function are used by the clinical laboratories. The first step in this diagnostic approach will be to rule out acause of secondary hyperparathyroidism (SHPT). Among these, the most frequent are vitamin D deficiency, very low calcium intake, impairedrenal function, malabsorptions, drugs interfering with calcium/bone metabolism, such as lithium salts and antiresorptive osteoporosis therapies,hypercalciuria due to a renal calcium leak. If no cause of SHPT are evidenced, the diagnosis of normocalcemic primary hyperparathyroidism(PHPT) should be considered. A calcium load test is a very useful tool for this diagnosis if it shows that serum PTH is not sufficiently decreasedwhen calcemia rises frankly above the upper normal limit. In a normocalcemic patient with hypercalciuria and a high serum PTH concentration,a thiazide challenge test may help to differentiate SHPT due to a renal calcium leak from normocalcemic PHPT.

Milk kefir is produced by fermenting milk in the presence of kefir grains. This beverage has several benefits for human health. The aim of this experiment was to analyze 5 kefir grains (and their products) using a targeted metagenetic approach. Of the 5 kefir grains analyzed, 1 was purchased in a supermarket, 2 were provided by the Ministry of Agriculture (Namur, Belgium), and 2 were provided by individuals. The metagenetic approach targeted the V1-V3 fragment of the 16S ribosomal (r)DNA for the grains and the resulting beverages at 2 levels of grain incorporation (5 and 10%) to identify the bacterial species population. In contrast, the 26S rDNA pyrosequencing was performed only on kefir grains with the aim of assessing the yeast populations. In parallel, pH measurements were performed on the kefir obtained from the kefir grains using 2 incorporation rates. Regarding the bacterial population, 16S pyrosequencing revealed the presence of 20 main bacterial species, with a dominance of the following: Lactobacillus kefiranofaciens, Lactococcus lactis ssp. cremoris, Gluconobacter frateurii, Lactobacillus kefiri, Acetobacter orientalis, and Acetobacter lovaniensis. An important difference was noticed between the kefir samples: kefir grain purchased from a supermarket (sample E) harbored a much higher proportion of several operational taxonomic units of Lactococcus lactis and Leuconostoc mesenteroides. This sample of grain was macroscopically different from the others in terms of size, apparent cohesion of the grains, structure, and texture, probably associated with a lower level of Lactobacillus kefiranofaciens. The kefir (at an incorporation rate of 5%) produced from this sample of grain was characterized by a lower pH value (4.5) than the others. The other 4 samples of kefir (5%) had pH values above 5. Comparing the kefir grain and the kefir, an increase in the population of Gluconobacter in grain sample B was observed. This was also the case for Acetobacter orientalis in sample D. In relation to 26S pyrosequencing, our study revealed the presence of 3 main yeast species: Naumovozymaspp., Kluyveromyces marxianus, and Kazachastania khefir. For Naumovozyma, further studies are needed to assess the isolation of new species. In conclusion, this study has proved that it is possible to establish the patterns of bacterial and yeast composition of kefir and kefir grain. This was only achieved with the use of high-throughput sequencing techniques. [less ▲]

The term ‘phytoestrogen’ is used to define a wide variety of nonsteroidal compounds that occur naturally in many plants. When they are absorbed by cows, these polyphenolic compounds undergo biotransformation by specific bacteria present in the gastrointestinal tract. The resulting metabolites are absorbed in the organism and some are excreted in milk. The impact of these compounds on human health divides opinion. Some scientists believe that they might have adverse health effects. Others believe the opposite, especially with regard to their microbial metabolites, such as equol. Whatever one's view on the subject, scientists need accurate, sensitive and rapid analytical methods in order to continue the research on clarifying the phytoestrogen issue. Cow's milk is an animal product that is common in the human diet, and it is therefore important to evaluate its content of phytoestrogen metabolites. In order to study the human intake of equol via commercial milk, an analytical method was developed and validated following EMA/CVMP/VICH/463202/2009 guidelines. Enzymatic hydrolysis was used to release the equol. It was then extracted using double liquid/liquid extraction and analyzed using UPLC®-MS/MS, with an analysis runtime of only 5 min. This analytical method produced a linear calibration curve with a high correlation coefficient (R2≥0.996) between 5 and 1,000 ng mL−1. Good intra- and inter-day precision (RSDs≤5.3% and ≤5.2%, respectively) and accuracy (bias≤8.6%) were achieved. The recovery rate differed slightly among the different types of milk, ranging between 60.6±1.09% and 82.3±5.21%. Good method repeatability was observed (RSDs<15%). There was neither a matrix effect nor a carry-over effect, and the sample extracts were stable during storage for at least 7 days at −21°C and 5°C. In order to apply the proposed method and obtain an initial estimate of equol concentration in cow’s milk in Belgium, 44 samples of various brands found in several supermarkets and 5 raw milk samples from Walloon farms were analyzed. Equol was found in all the samples analyzed, with a concentration ranging from 10 to 50 ng mL−1 for conventional milk and from 70 to 130 ng mL−1 for organic milk. These results were compared with other European studies and the same trend was observed. The results obtained show the specificity, sensitivity and precision of this method for analyzing oestrogenic metabolite-equol in cow’s milk. This study should be extended to include a greater number of samples and be implemented over a longer period to see if there is a correlation between livestock practice and/or sample origins with the equol content in milk. The addition of other phytoestrogen compounds with this method, using UPLC®-MS/MS technology, could also lead to more reliable monitoring of these compounds in dairy production. [less ▲]

Summary This study examines people’s and public actors’s perception of traditional healers in Kisenso, and their potential integration into the health system. The findings of this study are based on focus groups conducted in 2013. According to the key results of this study, 100% of participants acknowledge the existence of traditional practitioners and all have used them. 80% found the care provided by these healers to be effective. However, the study participants found them to be lacking in hygiene in their handling of products. The use of traditional healers is justified in particular by the effectiveness of care, the type of illness suffered, the possibility of credit payment and their proximity. Public actors recognize both the existence of traditional healers and their effectiveness. They deplore their clandestine operation. Traditional healers claiming to be GPs (60%) and specialists (40%) say they work illegally because of the cost of administrative acts and their mistrust of intellectuals and biomedical practitioners. They complain about the insolvency of their patients who do not honor their commitments. For an effective integration of traditional healers in the health system, it would be useful to remove administrative barriers imposed on them for a balance between ancestral legitimacy and illegality in which they work, give them access to training, accept them as full participants in the health system, and explore the possibilities of contracting.

This conceptual paper aims to respond to the poorly addressed question of the emergence of hybrid organizations – i.e. organizations that embrace several institutional logics. It does so by developing a model and a set of propositions focusing on the heterogeneity of the entrepreneurial team as a possible driver for hybridity throughout the entrepreneurial process and up to the emergence of a hybrid organization. As contributions to the literatures on (collective) entrepreneurship, imprinting and hybrid organizations, we advance several avenues and conditions under which the heterogeneity of the entrepreneurial team may imprint the entrepreneurial process and lead to the creation of hybrid organizations. Our propositions connect the individual, team and organizational levels and thus advance our understanding of how institutional logics can be combined across different levels of analysis and throughout the stages of an entrepreneurial process.
