Well, you have hepatic metastases: Use of technical language by medical students in simulated patient interviews.

OBJECTIVE: This research explored medical students' use and perception of technical language in a practical training setting to enhance skills in breaking bad news in oncology. METHODS: Terms potentially confusing to laypeople were selected from 108 videotaped interviews conducted in an undergraduate Communication Skills Training. A subset of these terms was included in a questionnaire completed by students (N=111) with the aim of gaining insight into their perceptions of different speech registers and of patient understanding. Excerpts of interviews were analyzed qualitatively to investigate students' communication strategies with respect to these technical terms. RESULTS: Fewer than half of the terms were clarified. Students checked for simulated patients' understanding of the terms palliative and metastasis/to metastasize in 22-23% of the interviews. The term ambulatory was spontaneously explained in 75% of the interviews, hepatic and metastasis/to metastasize in 22-24%. Most provided explanations were in plain language; metastasis/to metastasize and ganglion/ganglionic were among terms most frequently explained in technical language. CONCLUSION: A significant number of terms potentially unfamiliar and confusing to patients remained unclarified in training interviews conducted by senior medical students, even when they perceived the terms as technical. PRACTICE IMPLICATIONS: This exploration may offer important insights for improving future physicians' skills.

Early Stage Primary Bone Lymphoma: A Retrospective, Multicenter Rare Cancer Network Study

PURPOSE/OBJECTIVE(S): Primary bone lymphoma (PBL) represents less than 1% of all malignant lymphomas, and 4-5% of all extranodal lymphomas. In this study, we assessed the disease profile, outcome, and prognostic factors in patients with stage I and II PBL. MATERIALS/METHODS: Between 1987 and 2008, 116 consecutive patients with PBL treated in 13 RCNinstitutions were included in this study. Inclusion criteriawere: age.17 yrs, PBLin stage I and II, andminimum6months follow-up. The median agewas 51 yrs (range: 17-93).Diagnosticwork-up included plain boneXray (74%of patients), scintigraphy (62%), CT-scan (65%),MRI (58%), PET (18%), and bone-marrow biopsy (84%).All patients had biopsy-proven confirmation of non-Hodgkin's lymphoma (NHL). The histopathological type was predominantly diffuse large B-cell lymphoma (78%) and follicular lymphoma (6%), according to theWHOclassification. One hundred patients had a high-grade, 7 intermediate and 9 low-gradeNHL. Ninety-three patients had anAnn-Arbor stage I, and 23 had a stage II. Seventy-seven patients underwent chemoradiotherapy (CXRT), 12 radiotherapy (RT) alone, 10 chemotherapy alone (CXT), 9 surgery followed by CXRT, 5 surgery followed by CXT, and 2 surgery followed by RT. One patient died before treatment.Median RT dosewas 40Gy (range: 4-60).Themedian number ofCXTcycleswas 6 (range, : 2-8).Median follow-upwas 41months (range: 6-242). RESULTS: Following treatment, the overall response rate was 91% (CR 74%, PR 17%). Local recurrence was observed in 12 (10%) patients, and systemic recurrence in 17 (15%) patients. Causes of death included disease progression in 16, unrelated disease in 6, CXT-related toxicity in 1, and secondary cancer in 2 patients. The 5-yr overall survival (OS), disease-free survival (DFS), lymphoma- specific survival (LSS), and local control (LC) were 76%, 69%, 78%, and 92%, respectively. In univariate analyses (log-rank test), favorable prognostic factors for survival were: age\50 years (p = 0.008), IPI score #1 (p = 0.009), complete response (p\0.001), CXT (p = 0.008), number of CXT cycles $6 (p = 0.007), and RT dose . 40 Gy (p = 0.005). In multivariate analysis age, RT dose, complete response, and absence of B symptoms were independent factors influencing the outcome. There were 3 patients developing grade 3 or more (CTCAE.V3.0) toxicities. CONCLUSIONS: This large multicenter study, confirms the relatively good prognosis of early stage PBL, treated with combined CXRT. Local control was excellent, and systemic failure occurred infrequently. A sufficient dose of RT (. 40 Gy) and complete CXT regime (. 6 cycles) were associated with a better outcome. Combined modality appears to be the treatment of choice.

Production endogène de Nortestostérone chez l'homme et influence de l'activité physique et du régime alimentaire

RESUME Depuis les années 1980, les stéroïdes androgéniques anabolisants (SAA) sont restés les produits dopants les plus utilisés par les sportifs. Les propriétés principales attribuées à ces substances sont une augmentation de la masse et de la force musculaire ainsi qu'une agressivité supérieure pouvant s'avérer bénéfique lors des entraînements ou des compétitions. En plus de cette "tradition" liée à la consommation des SAA, une autre problématique est apparue dans le monde antidopage suite à la fulgurante expansion de l'utilisation des compléments alimentaires par les athlètes professionnels et amateurs. Dès la fin des années 1990, une recrudescence de cas positifs de dopage aux SAA a été attribuée à la contamination des compléments alimentaires par des composés anabolisants tels que la testostérone ou la nandrolone ou par des prohormones se situant en amont dans le métabolisme de certains SAA et conduisant à la présence, dans les urines, de traces de substances interdites par l'Agence Mondiale Antidopage (AMA). Afin de mettre en garde les autorités antidopage ainsi que les athlètes quant aux problèmes liés aux compléments alimentaires, le Laboratoire Suisse d'Analyse du Dopage (LAD) a décidé d'étudier de manière plus précise la composition d'une centaine de produits accessibles en Suisse par l'intermédiaire d'internet. Cette étude a permis de mettre en évidence un taux de non conformité des produits avoisinant les 20%, avec une contamination plus importante des produits contenant des hormones ou des prohormones. La consommation de doses journalières recommandées des produits contaminés a mené à la détection dans les urines de la présence de substances interdites par l'AMA. Ces résultats confirment ainsi que l'usage de compléments alimentaires peut s'avérer dangereuse dans le cadre de contrôles antidopage et que les effets sur l'état physique et mental des athlètes peuvent dépasser les effets désirés et être dramatiques pour la poursuite d'une carrière sportive. D'autre part, cela démontre que l'alimentation peut mener à la présence urinaire de substances proscrites telles que les métabolites de la nandrolone, la 19-norandrostéreone (19-NA) et la 19-norétiocholanolone (19-NE). Afin de démontrer un effet potentiel de l'exercice physique sur l'excrétion urinaire des métabolites de la nandrolone, une première étude clinique a été réalisée avec 34 volontaires. Deux doses orales de nandrolone marquée avec deux atomes de C13 ont été administrées aux sujets. Les urines ont été récoltées durant les 5 jours suivant les prises orales (études d'excrétion) ainsi qu'avant et après les 8 séances d'entraînements du protocole. Les analyses des études d'excrétion ont permis d'établir une variabilité intra- et inter-individuelle du métabolisme et de la pharmacocinétique de la 19-NA et de la 19-NE. En dépit de la rapide élimination urinaire des métabolites de la nandrolone C13, les analyses des échantillons prélevés avant et après les différents efforts n'ont pas révélé une influence nette de l'exercice physique sur les concentrations urinaires de la 19-NA et 19-NE. Une seconde étude clinique a été effectuée, avec la participation de 30 volontaires. Il s'agissait de déterminer si la consommation de multiples doses orales d'un décanoate de testostérone, de 19-norandrostenedione (un précurseur de la nandrolone) ou de placebo durant un mois, pouvait avoir des effets bénéfiques sur la récupération et la performance physique. En parallèle, les sujets étaient soumis à un entrainement d'endurance intense et individualisé. Divers paramètres physiologiques ont été étudiés dans le sérum et les urines afin de mettre en évidence une meilleure récupération de l'organisme. Aucun de ses paramètres n'a permis de conclure que la consommation orale de SAA est favorable pour optimaliser les capacités de récupération des athlètes. De plus, les performances physiques ont été évaluées avant et après l'entraînement et le traitement. Aucune différence significative n'a été démontrée entre les trois groupes de volontaires. L'état psychologique des volontaires a été évalué à l'aide de questionnaires (short Profile of Mood State, sPOMS) remplis à trois reprises au cours du protocole. De manière générale, l'évolution observée est une augmentation de la fatigue avec une diminution de la vigueur. Des analyses statistiques ont révélé que des prises orales de testostérone, et dans une moindre mesure de 19-norandrostenedione, ont une légère influence sur cette évolution générale en diminuant les effets de l'entrainement sur le profil psychologique. Les urines récoltées durant le protocole ont été analysées par GC/C/IRMS et GCMS afin de détecter les variations des concentrations des hormones liées au métabolisme de la testostérone. Les résultats ont démontré une variabilité interindividuelle du métabolisme de la testostérone qui implique que les critères de positivité imposés par l'AMA ne sont pas forcément valables pour tous les individus. La détection de la 19-NA et de la 19-NE, issus du métabolisme in vivo de la 19norandrostenedione, a confirmé les résultats obtenus sur la pharmacocinétique et le métabolisme de la nandrolone C13 obtenus lors de la première étude clinique. Ce travail a permis de clarifier certains points en lien avec l'abus de la nandrolone dans le sport et notamment par rapport à la consommation de compléments alimentaires. Les deux études cliniques n'ont pas véritablement apporté les réponses souhaitées aux hypothèses de départ. Cependant certains aspects intéressants en relation avec le métabolisme des SAA ont été découverts et pourront peut-être permettre à la lutte antidopage d'évoluer vers une meilleure efficacité. SUMMARY Since 1980's, anabolic androgenic steroids (AAS) are still the most used doping agents in sports. The main properties attributed to these substances are an increase of muscle mass and strength and also a higher aggressiveness that could be beneficial during trainings and competitions. In addition to this "tradition" linked to the AAS intake, another problematics has raised in the antidoping field. Indeed, nutritional supplements have been more and more used by professional and amateur athletes. Since the end of the 1990's, an outburst of positive doping cases with AAS has been attributed to nutritional supplements contaminations with anabolic compounds like testosterone or nandrolone or with prohormones located above in the metabolism of some AAS and prompting urinary traces of forbidden compounds by the World Antidoping Agency (WADA). In order to inform the antidoping authorities and the athletes about the problems linked to the nutritional supplements, the Swiss Laboratory for Doping Analyses (LAD) decided to investigate more precisely the composition of about hundred products accessible in Switzerland through different web sites. This study showed that about 20% of the products were not conformed to the composition announced by the manufacturers. The oral intake of daily recommended doses of the contaminated products revealed the presence in urines of forbidden substances by the WADA. Hence, these results confirm that the use of nutritional supplements can lead to adverse analytical findings in antidoping controls and that the effects on athletes' physical and mental state could be different from the ones desired and could be dramatic for the continuation of an athlete's career. Moreover, this demonstrates that the diet can lead to the presence in urines of proscribed substances like nandrolone metabolites, i.e. 19-norandrosterone (19-NA) and 19-noretiocholanolone (19-NE). To put forward a potential effect of physical exercise on urinary nandrolone metabolites excretion rate, a first clinical study was done with 34 volunteers. Two oral doses of nandrolone labelled with two C13 atoms were administered to the subjects. The urines were collected during the 5 days following the treatment (excretion studies) and before and after the 8 exercise sessions of the protocol. The analyses of excretion studies revealed an intra- and inter-individual variability of the metabolism and the pharmacokinetics of 19-NA and 19-NE. In spite of the rapid urinary elimination of the nandrolone C13 metabolites, the analyses of the urine samples gathered before and after efforts did not show a clear influence of physical exercise on the urinary 19-NA and 19-NE concentrations. A second clinical study was done with the participation of 30 volunteers. The main aim was to determine if multiple oral doses of testosterone undecanoate, 19-norandrostenedione (a nandrolone precursor) or placebo during one month, could have beneficial effects on recovery and physical performance. Meanwhile, the individuals had to follow an intense and personalized endurance training program. Several physiological parameters were investigated in serum and urines in order to demonstrate a better organism's recovery. None of these parameters lead to the conclusion that oral intake of AAS is useful to optimise the recovery capacities of athletes. In addition, physical performances were evaluated before and after the training and treatment month. No significant difference was shown between the three volunteers groups. The psychological state of the volunteers was assessed through questionnaires (short Profile of Mood State, sP4MS) filled three times during the protocol. The global evolution is an increase of fatigue with an decrease of vigour. Statistical analyses revealed that the oral intake of testosterone, and to a lesser extent of 19= norandrostenedione, have a small influence on this general evolution in decreasing the effect of training on the psychological profile. The urines collected during the protocol were analysed by GC/C/IRMS and GCMS to detect concentrations variations of hormones related to the testosterone metabolism. The results revealed an interindividual variability of testosterone metabolism which implies that the guidance concerning endogenous steroids prescribed by the WADA are not uniformly valid for all individuals. Detection of 19-NA and 19-NE, coming from the in vivo metabolism of 19norandrostenedione, confirmed the results previously obtained on the pharamcokinetics and metabolism of the nandrolone C13 in the first clinical study. This work allowed to clarify some aspects linked to nandrolone abuse in sports and noteworthy related to nutritional supplements intake. The two clinical studies did not really bring plain answers to the basal hypotheses but some interesting aspects in relation with AAS metabolism were put forth and would perhaps allow an evolution of a more effective fight against doping.

Utilité des outils d'aide à la prise médicamenteuse pour améliorer l'adhésion au traitement: revue Cochrane pour le praticien

Avulsion fracture of peroneus longus tendon at the first metatarsal insertion: a case report : P16

Introduction: Isolated avulsion fracture at the plantar lateral base of the first metatarsal (M1) is very rare. Case report: A 35 year old overweight woman sustained an eversion strain of her right foot. Despite pain along M1 she was able to continue walking for three days before presenting to her family doctor. Swelling on the plantar aspect of the foot was noticed, there was also pain at eversion of the foot and extension of the ankle. Plain X-ray showed no abnormalities. A MRI showed minimal bone bruise at the basis of M1 and a partial rupture of the peroneus longus tendon at its insertion. The patient was allowed to walk with partial weight bearing with a soft ankle brace. After 6 months she presented at our hospital because of persistent pain. There was still a painful insertion of the peroneus longus but active plantarflexion of M1 was possible. Plain X-rays were poorly contributive except for a discrete flattening of the longitunal arch. CT-scan showed a non displaced fracture at the M1-basis. A protocol with partial weight-bearing in a short-leg cast and partial weight-bearing orthosis each for 6 weeks was unsuccessfully attempted. Therefore, an excision of the non healed bone fragment at the basis of M1 and a first tarsometatarsal joint arthrodesis were performed. Postoperatively the patient wore a partial weight-bearing short leg cast for 6 weeks followed by a weight-bearing short leg cast for 6 weeks with favourable outcome. Discussion: Initial internal fixation has been reported to lead to good results [1, 2]. In our case the conservative treatment failed and leaded to non union. At that time we considered as too risky (overweight) to excise the fragment and reattach the peroneus longus tendon. Therefore, we excised the fragment and fused the first tarsometatarsal joint. This procedure allowed, at least partially, to compensate for the function of the peroneus longus tendon. 1 Murakami T, et al.

Imagerie et arthrose [Imaging in osteoarthritis].

Plain radiography remains useful for the diagnosis of osteoarthritis, even if it is not always essential. It is moreover poorly correlated with symptoms, as it reflects rather the accumulation of damage then active processes. Similarly, it is a poor indicator of the progression of osteoarthritis. Modem imaging, particularly MRI, has allowed us to understand better the evolving processes, demonstrating a good correlation with symptoms and a better predictive value of clinical course. It has gradually replaced standard radiography in the study because it directly demonstrates sequelae and the active processes in all the structures of the joint. It remains clinically indicated only to exclude an alternative diagnosis or to determine a possible complication of osteoarthritis.

A recent inventory of the bats of Mozambique with new documentation of 7 new species for the country

The bat fauna of Mozambique is poorly documented. We conducted a series of inventories across the country between 2005 and 2009, resulting in the identification of 50 species from 41 sites. Of these, seven species represent new national records that increase the country total to 67 species. These data include results from the first detailed surveys across northern Mozambique, over an area representing almost 50% of the country. We detail information on new distribution records and measurements of these specimens. Special attention is paid to the Rhinolophidae, because these include several taxa that are currently in a state of taxonomic confusion. Furthermore, we also present some notes on taxonomy, ecology and echolocation calls. Finally, we combine modelled distributions to present predicted species richness across the country. Species richness was lowest across the coastal plain, to the east and far north, and is predicted to increase in association with rising altitude and higher topographic unevenness of the landscape.

Perinuclear Mlp proteins down-regulate gene expression in response to a defect in mRNA export

Résumé Une caractéristique des cellules eucaryotes est le confinement du matériel génétique (ADN/DNA) dans le noyau. Pour décoder cette information, un ARN messager (mRNA) est d'abord transcrit sous forme d'un ARN prémessager (pré-mRNA). Ce-dernier doit subir plusieurs étapes de maturation pour aboutir à une particule ribonucléoprotéique (mRNP) qui sera exportée vers le cytoplasme et traduite en protéine. La protéine de levure Mex67p et son homologue humain TAP sont des récepteurs d'export médiant la translocation du mRNP au travers des complexes du pore nucléaire (NPC). Mex67p/TAP ne se lient pas directement au mRNA, mais nécessitent la présence de protéines adaptatrices, telles que Yra1p et son homologue humain REF1. Afin d'identifier de nouveaux facteurs impliqués dans l'export des mRNPs ou de nouvelles fonctions pour Yra1p, nous avons effectué un crible génétique avec un mutant thermosensible de Yra1p, GFP-yra 1 -8. Ce mutant présente un défaut d'export des mRNAs et une diminution des niveaux de transcrits du gène rapporteur LacZ ainsi que de certains transcrits endogènes. Nous avons trouvé que la perte de Mlp2p, ou d'une protéine hautement similaire, Mlp1p, restaure la croissance du mutant GFP-yra1-8 à température restrictive. Mlp1p et Mlp2p sont des protéines nucléaires, dont l'homologue humain est TPR. Les Mlp (myosin¬like proteins) ainsi que TPR forment des structures filamenteuses ancrées aux NPC. Bien que la fonction des Mlp ne soit pas clairement définie, un rôle dans la biogenèse et la surveillance des mRNPs a été récemment proposé. Notre étude montre que la perte des Mlp, non seulement restaure la croissance de GFP-yra1-8, mais augmente aussi les niveaux des transcrits LacZ et facilite leur apparition dans le cytoplasme. Des expériences d'immunoprécipitations de la chromatine révèlent que Mlp2p diminue le taux de synthèse du transcrit LacZ dans GFP-yra1-8. Des analyses du transcriptome montrent que Mlp2p réduit aussi les niveaux d'une population de transcrits endogènes dans le mutant. Finalement, des localisations in situ suggèrent que la transcription du rapporteur LacZ a lieu à la périphérie du noyau, à proximité des Mlp. Ainsi, les protéines Mlp pourraient préférentiellement diminuer la transcription de gènes exprimés à la périphérie nucléaire. Nous montrons aussi que Yra1p interagit génétiquement avec Nab2p une protéine liée au mRNA et impliquée dans son export, mais non avec d'autres protéines également impliquées dans l'export des mRNAs. Les résultats obtenus soutiennent un modèle où les protéines Yra1p et Nab2p sont nécessaires à l'arrimage des mRNPs sur la plate-forme des Mlp. Si ces signaux manquent ou sont défectueux, les mRNPs ne peuvent pas poursuivre leur trajet vers le canal central du NPC. Ce bloc induirait par la suite une diminution de la transcription d'une population de gènes potentiellement localisée à la périphérie nucléaire. Dans son ensemble, cette étude suggère que les protéines Mlp établissent un lien entre la transcription de certains mRNAs et leur export au travers du pore nucléaire. Summary A hallmark of the eukaryotic cell is the packaging of DNA in the nucleus. To decode the genetic information, a messenger RNA (mRNA) is first synthesized as a pre-mRNA molecule, which undergoes different maturation steps resulting in an mRNP (messenger RNA ribonucleoprotein), which can be actively transported to the cytoplasm and translated into a protein. Yeast Mex67p and its human homologue TAP are export receptors mediating mRNP translocation through the nuclear pore complex (NPC). The recruitment of Mex67p/TAP to mRNA is mediated by mRNA export adaptors of the evolutionarily conserved REF (RNA and Export Factor binding) family: yeast Yra1p and human REF1. To uncover new functions of Yra1p or new factors implicated in mRNA export, we performed a genetic screen with a themiosensitive (ts) yra1 mutant, GFP-yra1-8. This mutant exhibits mRNA export defects and a decrease in the levels of LacZ reporter and certain endogenous transcripts. We found that the loss of Mlp2p, or the related Mlp1p protein, substantially rescues the growth defect of the GFP-yra1 -8 mutant. Mlp1p and M1p2p are large non-essential proteins, homologous to human TPR, proposed to form intra-nuclear filamentous structures anchored at the NPC. Their role is not clearly defined, but they have been implicated in mRNP biogenesis and surveillance. Our study shows that loss of Mlp proteins not only restores growth of GFP-yra1-8, but also rescues LacZ mRNA levels and increases their appearance in the cytoplasm. Chromatin immunoprecipitation and pulse chase experiments indicate that Mlp2p down-regulates LacZ mRNA synthesis in GFP-yra1-8. DNA micro- array analyses reveal that Mlp2p also reduces the levels of a subset of cellular transcripts in the yra1 mutant strain. In situ localizations suggest that LacZ transcription occurs at the nuclear periphery, in close proximity to Mlp proteins. Thus, Mlp proteins may preferentially down-regulate genes expressed at the nuclear periphery. Finally, we show that Yra1p genetically interacts with the shuttling mRNA-binding protein Nab2p and that loss of Mlp proteins rescues the growth defect of yra1 and nab2, but not other mRNA export mutants. The data support a model in which Nab2p and Yra1p are required for rnRNP docking to the Mlp platform. Lack of these signals prevents mRNPs from crossing the Mlp gate. This block may then negatively feed-back on the transcription of a subset of genes, potentially located at the nuclear envelope. Overall, this study suggests that perinuclear Mlp proteins establish a link between mRNA transcription and export.

Detection of smuggled cocaine in cargo using MDCT.

OBJECTIVE: Smuggling dissolved drugs, especially cocaine, in bottled liquids is an ongoing problem at borders. Common fluoroscopy of packages at the border cannot detect contaminated liquids. The objective of our study was to develop an MDCT screening method to detect cocaine-containing vessels that are hidden between uncontaminated ones in a shipment. MATERIALS AND METHODS: Studies were performed on three wine bottles containing cocaine solutions that were confiscated at the Swiss border. Reference values were obtained by scans of different sorts of commercially available wine and aqueous solutions of dissolved sugar. All bottles were scanned using MDCT, and data evaluation was performed by measuring the mean peak of Hounsfield units. To verify the method, simulated testing was performed. RESULTS: Using measurements of the mean peak of Hounsfield units enables the detection of dissolved cocaine in wine bottles in a noninvasive and rapid fashion. Increasing opacity corresponds well with the concentration of dissolved cocaine. Simulated testing showed that it is possible to distinguish between cocaine-contaminated and uncontaminated wine bottles. CONCLUSION: The described method is an efficacious screening method to detect cocaine-contaminated bottles that are hidden between untreated bottles in cargo. The noninvasive examination of cargo allows a questionable delivery to be tracked without arousing the suspicion of the smugglers.

Sources d'exposition aux phtalates dans une unité de soins néonatals [Phthalate exposure in the neonatal intensive care unit].

There are growing concerns on long-term health consequences, notably on fertility rates, of plasticizers such as phthalates. While di(2-ethylhexyl)phthalate (DEHP) is currently used in several medical devices, newborns in the neonatal intensive care unit are both more exposed and more vulnerable to DEHP. The objectives of this study were to identify, count, and describe possible sources of DEHP in a neonatal care unit. Our method consisted in the listing and the inspection of the information on packaging, complemented by contact with manufacturers when necessary. According to the results, 6% of all products and 10% of plastic products contained some DEHP; 71% of these involved respiratory support devices. A vast majority of the items showed no information on the content of DEHP. Further research is needed, particularly to determine the effects of such an early exposure and to study and develop safer alternatives.

Mid- to Late Holocene shoreline reconstruction and human occupation in Ancient Eretria (South Central Euboea, Greece)

Few studies have aimed to reconstruct landscape change in the area of Eretria (South Central Euboea, Greece) during the last 6000 years. The aim of this paper is to partially fill in this gap by examining the interaction be- tween Mid- to Late Holocene shoreline evolution and human occupation, which is documented in the area from the Late Neolithic to the Late Roman period (with discontinuities). Evidence of shoreline displacements is derived from the study of five boreholes (maximum depth of 5.25 m below the surface) drilled in the lowlands of Eretria. Based on sedimentological analyses and micro/macrofaunal identifications, different facies have been identified in the cores and which reveal typical features of deltaic progradation with marine, lagoonal, fluvio- deltaic and fluvial environments. In addition, a chronostratigraphy has been obtained based on 20 AMS 14C radio- carbon dates performed on samples of plant remains and marine/lagoonal shells found in situ. The main sequences of landscape reconstruction in the plain of Eretria can be summarized as follows: a marine environ- ment predominated from ca. 4000 to 3200 cal. BC and a gradual transition to shallow marine conditions is ob- served ca. 3200-3000 cal. BC due to the general context of deltaic progradation west of the ancient city. Subsequently, from ca. 3000 to 2000 cal. BC, a lagoon occupied the area in the vicinity of the Temple of Apollo and the settlement's development was restricted to several fluvio-deltaic levees, thus severely limiting human activities in the plain. From ca. 2000 to 800 cal. BC, a phase of shallow marine presence prevailed and constrained settlement on higher ground, forcing abandonment of the major part of the plain. Finally, since the eighth century BC, the sea has regressed southward and created the modern landscape.

Forensic intelligence for medicine anti-counterfeiting

Medicine counterfeiting is a crime that has increased in recent years and now involves the whole world. Health and economic repercussions have led pharmaceutical industries and agencies to develop many measures to protect genuine medicines and differentiate them from counterfeits. Detecting counterfeit is chemically relatively simple for the specialists, but much more information can be gained from the analyses in a forensic intelligence perspective. Analytical data can feed criminal investigation and law enforcement by detecting and understanding the criminal phenomenon. Profiling seizures using chemical and packaging data constitutes a strong way to detect organised production and industrialised forms of criminality, and is the focus of this paper. Thirty-three seizures of a commonly counterfeited type of capsule have been studied. The results of the packaging and chemical analyses were gathered within an organised database. Strong linkage was found between the seizures at the different production steps, indicating the presence of a main counterfeit network dominating the market. The interpretation of the links with circumstantial data provided information about the production and the distribution of counterfeits coming from this network. This forensic intelligence perspective has the potential to be generalised to other types of products. This may be the only reliable approach to help the understanding of the organised crime phenomenon behind counterfeiting and to enable efficient strategic and operational decision making in an attempt to dismantle counterfeit network.

Le Briançonnais, terrain exotique dans les Alpes ?

New reconstructions of the Western Alps from late Early Jurassic till early Tertiary are proposed. These reconstructions use deep lithospheric data gathered through recent seismic surveys and tomographic studies carried out in the Alps. The present day position, under the Po plain, of the southern limit of the European plate (fig. 1), allows to define the former geometry of the Brianconnais peninsula. The Brianconnais domain is regarded as an exotic terrane formerly belonging to the European margin until Late Jurassic, then transported eastward during the drift of Iberia (fig. 5). Therefore, on a present day Western Alps cross section, a duplication of the European continental margin can be recognized (fig. 10). Stratigraphic and sedimentological data along a zone linking the Pyrenean fracture zone to the Brianconnais, can be related to a rifting event starting in Oxfordian time. This event is responsible for the Late Jurassic till mid-Cretaceous drift of Iberia opening, first the northern Atlantic, then the Gulf of Biscay. Simultaneously, the drift of the Brianconnais will open the Valais ocean and close the Piemontese ocean. The resulting oblique collision zone between the Brianconnais and the Apulian margin generates HP/LT metamorphism starting in Early Cretaceous. The eastward drift of the Brianconnais peninsula will eventually bring it in front of a more northerly segment of the former European margin. The thrusting of the Brianconnais unto that margin takes place in early Tertiary (fig. 9), following the subduction of the Valais ocean. The present nappe pile results not only from continent/continent frontal collision, but also from important lateral displacement of terranes, the most important one being the Brianconnais. The dilemma of `'en echelon'' oceanic domains in the Alps is an outcome of these translations. A solution is found when considering the opening of a Cretaceous Valais ocean across the European margin, running out eastward into the Piemontese ocean, where the drift is taken up along a former transform fault and compensated by subduction under the Apulian margin (fig. 8). In the Western Alps we are then dealing with two oceans, the Piemontese and the Valaisan and a duplicated European margin. In the Eastern Alps the single Piemontese ocean is cut by newly created oceanic crust. All these elements will be incorporated into the Penninic structural domain which does not represent a former unique paleogeographic area, it is a composite accretionary domain squeezed between Europe and Apulia.

Subduction of continental crust in the Western Alps

As a result of recent deep reflection and refraction seismology the crustal structure of the Western Alps is now quite well-defined. However, this raises the question of what is present below the Moho, such as a crustal eclogitic root. This study attempts to estimate the volume of this eclogitic root on the basis of palinspastic reconstructions. Even with a minimum estimate of the crustal material involved in the subduction processes which took place during the Alpine orogeny, a significant eclogitized crustal root must be present down to depths of around 100 km below the Po plain. A maximum estimate suggests that a large part of this root could now be recycled in the asthenosphere.

Appendix: expert paper

Nanotechnology has been heralded as a "revolution" in science, for two reasons: first, because of its revolutionary view of the way in which chemicals and elements, such as gold and silver, behave, compared to traditional scientific understanding of their properties. Second, the impact of these new discoveries, as applied to commerce, can transform the daily life of consumer products ranging from sun tan lotions and cosmetics, food packaging and paints and coatings for cars, housing and fabrics, medicine and thousands of industrial processes.9 Beneficial consumer use of nanotechnologies, already in the stream of commerce, improves coatings on inks and paints in everything from food packaging to cars. Additionally, "Nanomedicine" offers the promise of diagnosis and treatment at the molecular level in order to detect and treat presymptomatic disease,10 or to rebuild neurons in Alzheimer's and Parkinson's disease. There is a possibility that severe complications such as stroke or heart attack may be avoided by means of prophylactic treatment of people at risk, and bone regeneration may keep many people active who never expected rehabilitation. Miniaturisation of diagnostic equipment can also reduce the amount of sampling materials required for testing and medical surveillance. Miraculous developments, that sound like science fiction to those people who eagerly anticipate these medical products, combined with the emerging commercial impact of nanotechnology applications to consumer products will reshape civil society - permanently. Thus, everyone within the jurisdiction of the Council of Europe is an end-user of nanotechnology, even without realising that nanotechnology has touched daily life.
