Drug counterfeiting is a sad and worrisome reality, especially in developing countries where quality control is not effective and sometimes not existing at all despite political will of governments. The consequences are harmful in particular for substandard medicines that pose more threats to populations in those countries due to their direct negative impact on patients such as failure of medical treatment including development of drug resistance and even death. Socio-economic consequences and negative reputation concerning the pharmaceutical industry are also observed. Unfortunately accurate detailed data on such medicines are not easy to obtain. Most of the time available data are often estimated from case reports or studies carried out in a specific area and during a defined period.Health authorities’ in the Democratic Republic of Congo are trying to identify this scourge by set up several strategies to fight against. One of them is built on the best knowledge of drugs from several horizons through the assessment of their quality to allow appropriate measurement. In this context, we have focused our study towards amoxicillin alone and/or combined with potassium clavulanate since it is one the very used medicines in pediatric medications. The formulations are powder for suspension. Two analytical methods were developed based on the USP monography, applying isocratic liquid chromatography. Prior to their application in routine, we evaluated the suitability of these methods through validation applying the accuracy profile of total error. Since it was planned to transfer the methods to DRC, several operating factors were taken into account namely operator, day and equipment. Interesting results were obtained in terms of trueness (relative biases below than 2.3%), precision (RSD of Intermediate precision below 2.8%), accuracy (beta-expectation tolerance intervals between -6.0% and 3.8%) for the concentration levels of interest. The latter were able to allow monitoring the quality of the two active ingredients here above in the 65 samples from Congolese market. They were collected in Kinshasa, Lubumbashi, Matadi and Kolwezi at official and non-official medicines distributors, in peripheral area. The dramatic results obtained confirm that substandard and counterfeit medicines remain a crucial problem on public health in low-income countries. Appropriate measures are really needed to set up the drug quality improvement. [less ▲]

tStudy region: Senegal River Delta. Study focus: The Senegal River Delta is a strategic region for the development of irri-gated agriculture. Despite a Sahelian climatic context, the management of the river withdams ensures water availability throughout the year. With the intensification of agri-culture, degradation of cultivated soils is observed, mostly linked to the existence of ashallow salty aquifer. In this context, regional surveys were performed to characterizegroundwater–surface water interactions and to identify the impact of artificial river man-agement and agricultural intensification on the evolution of groundwater dynamics andchemistry.New hydrological insights for the region: Results show that groundwater far away from riversand outside irrigated plots has evolved from marine water to brines under the influenceof evapotranspiration. Near rivers, salinity of groundwater is lower than seawater andgroundwater mineralization seems to evolve in the direction of softening through cationicexchanges related to permanent contact with fresh water. Despite large volumes of waterused for rice cultivation, groundwater does not show any real softening trend in the culti-vated parcels. Results show that the mechanisms that contribute to repel salt water fromthe sediments correspond to a lateral flush near permanent surface water streams and notto vertical drainage and dilution with rainfall or irrigation water. It is however difficultto estimate the time required to come back to more favorable conditions of groundwatersalinity. [less ▲]

Understanding consciousness remains one of the greatest mysteries for science to solve. How do our brains work? How can we know if some patients in coma have any consciousness left and how could we communicate with them? What are near-death experiences? What is brain death? What happens in our brains during dreaming, hypnosis or meditation? At present, nobody understands how matter (our trillions of neural connections) becomes perception and thought. We will here briefly review some neurological facts on consciousness and impaired consciousness. Thanks to recent advances in (neuroimaging) technology, the mapping of conscious perception and cognition in health (e.g., conscious waking, sleep, dreaming, hypnosis, meditation, sleepwalking and anesthesia) and in disease (e.g., coma, near-death, “vegetative” state, seizures, hallucinations etc) is providing exiting new insights into the functional neuroanatomy of human consciousness. Our perception of the outside world (sensory awareness; what we see, hear, etc.) and our awareness of an inner world (self-awareness; the little "voice" inside that "speaks" to ourselves) seemingly depend on two separate networks we could recently identify. Philosophers might argue that the subjective aspect of the mind will never be sufficiently accounted for by the objective methods of reductionistic science. We here prefer a more pragmatic approach and remain naively optimistic that technological advances might ultimately lead to an understanding of the neural substrate of human consciousness. [less ▲]

Continuous-flow micro- and mesofluidic reactors come with inherent properties that can be advantageously utilized for expanding the horizon of synthetic organic chemistry. Accurate control over local process parameters, even under extreme conditions, inherent safety, production homogeneity and seamless scale-up are amongst the most important assets of continuous-flow chemistry. Besides, flow chemistry enables the design of efficient multistep processes with significantly reduced footprints. In this lecture, we will discuss some of the most fascinating aspects of continuous-flow micro- and mesofluidic reactors in the specific context of preparative organic chemistry. Multiple examples illustrating the development and implementation of continuous-flow multistep strategies for the synthesis of high-value added organic targets will be presented. [less ▲]

Plasma rich platelets (PRP) consist of blood plasma with a high concentration of platelets autologous constituting a huge reservoir of growthfactors. The clinical use of the PRP is widespread in various medical applications. Even it is very popular with athletes, the use of PRP intendinopathies is still scientifically discussed, particularly related to a disparity in the products called PRP. In order to optimize employment, itshould be interested in the different stages of obtaining of the PRP. In this literature review, we analyzed in particular 8 parameters that can influencethe quality of the PRP: (1) anticoagulants used to preserve the best feature of platelet; (2) centrifuge speeds used in order to extract platelets; (3)platelet concentrations and the presence of leukocytes and erythrocytes in the PRP; (4) the platelet activators for the mast of platelets and thus therelease of growth factors; (5) use of local anesthetics to achieve infiltration, in addition to these parameters, it might be interesting to analyze othervariables like: (6) employment or not of buffer to neutralize the acidity caused by anticoagulants; (7) injection under US guidance or not; and (8)volume of PRP injected to determine their influence on the healing potential.

Short abstract Based on ethnographic fieldwork conducted among Moroccan women living in Milan hinterland in Italy, this paper aims at exploring the negotiated ways of performing both cultural and social belongings through food and at pointing out how these two dimensions can diverge or overlap in practice. Long abstract Migration constitutes for human beings an opportunity – among others – to develop a reflexive gaze upon one’s own habits (Rodier 2010), food habits in the case under study. In fact, not only changes that may occur in the ways of eating, cooking and supplying of produces, but also new relationships push individuals to question their everyday practices, which are associated with specific meanings. These meanings are socially and culturally oriented and performative, since they permit to state belongings as well as to take part to differently defined groups. In order to study these dynamics, I will present some ethnographic data collected during a research among Moroccan women living in Milan hinterland in Italy, mainly focusing on the history of two of them. The description of food practices, embedded in the narration of the migration experience and its consequences, which in its turn interacts with contextual discourses around immigrants and cultural diversity, reveals unexpected strategies to take social and cultural positionings within the collectivity. The theoretical framework upon which my analysis relies consists of a praxeological approach to subjectivation (Warnier 2001) combined with the consideration of the multi-dimensionality of the self which is derived from the intersectional perspective on identity (Crenshaw 1989; Anthias 2002; Yuval-Davis 2006). Through concrete practices involving food, individuals – women in this case – define their self as a layered complex of belongings, and they do that at both social and cultural level; thus proving how these two dimensions can diverge or overlap.

Outlier detection techniques in spatial data should allow to identify two types of outliers: global and local ones. Local outliers typically have non-spatial attributes that strongly differ from those observed on their neighbors. Detecting local outliers requires to be able to work locally, on neighborhoods, in order to take into account the spatial dependence between the statistical units under consideration, even though the outlyingness is usually measured on the non-spatial variables. Many procedures have been outlined in the literature, but their number reduces when one wants to deal with multivariate non-spatial attributes. In this paper, focus is on the multivariate context. A review of existing procedures is done. A new approach, based on a two-step improvement of an existing one, is also designed and compared with the benchmarked methods by means of examples and simulations. [less ▲]

La plupart des espèces d’ânes sauvages et domestiques est en danger d’extinction. Leur préservation nécessite la cryoconservation du sperme, des ovocytes et des embryons. L’objectif de cette étude était de mettre au point une technique de collecte in vivo et de maturation in vitro des ovocytes d’ânesses. Les ovocytes ont été collectés par ponction folliculaire transvaginale sous guide échographique, placés dans un milieu de maturation in vitro pendant 24, 30, 34 ou 38 heures puis analysés. Quatre-vingt-douze ovocytes ont été collectés dans 193 follicules (48%) avec une moyenne de 4,2 ovocytes par ânesse. Après 34 heures de maturation in vitro, 45% des ovocytes ont été matures. Pour la première fois une technique de collecte in vivo et de maturation in vitro d’ovocytes d’ânesses a été développée. Cette technique permet d’envisager la cryoconservation et la fécondation in vitro de ces ovocytes. [less ▲]
