Theoretical background: Cannabis is the most commonly used illicit drug among teenagers. Initiation is influenced by environmental factors and personal characteristics, events or experiences. An early initiation increases the risks of problems related to cannabis use (e.g. negative psychosocial effects, delinquent behaviors, mental disorders). Prevent initiation, through the identification of risk/protective factors and their interaction, seems crucial in terms of public health. Research question and significance: This study aimed to examine the progression of use, to identify protective and risk factors of cannabis initiation (including peers, alcohol, expectancies and internalizing factors) and to specifically focus on the influence of social anxiety and its moderators/mediators. Methods: A questionnaire was administered twice to 877 teenagers (49.94% female, M=15.61) with one year interval. Sex, age, demographic variables, peer cannabis use, cannabis-related variables (lifetime, frequency, problems and expectancies), alcohol use, social anxiety, trait-anxiety and depression were assessed through validated scales. Logistic regressions, mediation and moderation analyzes were performed. Results: During the follow-up period, 12.89% of the young participants initiated cannabis use. Several factors significantly predict initiation: alcohol use, peer users, perceptual enhancement and craving effect expectancies. Others factors significantly protect from initiation: negative behavioral effect expectancies and social anxiety. Gender, age, relaxation/social facilitation and cognitive impairment effect expectancies, trait-anxiety and depression do not significantly influence cannabis use initiation. In moderated mediation model, after controlling for relevant variables, social anxiety protected from initiation trough the mediating role of perceptual enhancement and craving effect expectancies. The number of peer users and alcohol use do not moderate this mediation. Negative behavioral effect expectancies do not significantly mediate the relation between social anxiety and cannabis initiation. Interpretation of findings: Through low positive expectancies, adolescents with social anxiety symptoms are less likely to initiate cannabis use than the others, whatever the number of peer users and the alcohol use. Findings are discussed in terms of risk and protective characteristics of relevant factors, in an overall and evolutionary approach including internalizing factors. Results support the identification of internalizing profile of adolescents concerned by prevention or treatment and the importance of social anxiety and expectancies in intervention. [less ▲]

Even though its use becomes common, cannabis remains a narcotic, the risks of which are nowadays better known. Its therapeutic value still needs to be scientifically demonstrated.

Egg and larval cannibalism was characterized in the European anchovy (Engraulis encrasicolus) during the spawning season in the North Aegean Sea. About 3 % of the sampled fish had consumed eggs and 7 % larvae. Egg consumption was observed during the night and larval consumption during the day. Cannibalism seems to be an opportunistic feeding strategy of anchovy, depending on prey availability and proximity of adults, larvae and eggs in relation with the diel vertical migrations of the fish.

OBJECTIVE: Cardiac lymph is the most direct medium for analyzing metabological changes in the myocardial cell. Currently, dogs are the animals used for investigation of myocardial lymphatic function. However, questions arise when comparing and interpreting the human system to the experimental model, since the dog coronary anatomy is different from human anatomy and pulmonary lymph contamination is found in up to 81% of the cases. Swine, having similar coronary anatomy to humans, are a proven model for cardiovascular research. The purpose of this study was to investigate the cardiac lymphatic anatomy of the swine and to develop a reliable cannulation technique to collect the lymph. METHODS AND RESULTS: The lymphatic anatomy of 60 pigs was studied and classified and a new technique for lymphatic cannulation was developed. The cannulation success rate was 55%. In addition, no pulmonary lymph contamination was found at the cannulation site. CONCLUSION: We conclude that porcine myocardial lymphatics can be successfully cannulated for the investigation of myocardial lymphatic function. [less ▲]

Gustave Lanson considérait les productions mineures comme le tissu conjonctif de l’histoire littéraire. Un tel point de vue peut rapidement faire apparaître les Physiologies parisiennes des années 1830-1845 comme le laboratoire de bien des esthétiques modernes, ce corpus étant d’autant plus inventif qu’il procède pour une grande part des poétiques d’écriture hybrides et expansives de la presse. Parce qu'elles sont enclines à traiter du personnel, des lieux et des pratiques littéraires à partir d'une fraction symboliquement réprouvée, sinon marginale, de la production littéraire, les Physiologies peuvent assumer tout à la fois une fonction de régulation et de révélation des processus de légitimation. L'article met en évidence ce double rôle d'élucidation et d'observation participante manifestée par ces textes. [less ▲]

A method for predicting water quality by linear regression using aquatic bryophy te canonical variables as predictors is presented. An example of application in the Alsatian Rhine valley is developed. The /--squared obtained before and after cross-validation reached 0.68 and 0.58 for the standard deviation of temperatures, 0.55 and 0.46 for the logarithm of the mean concentrations of N-NH4+, 0.52 and 0.43 for the logarithm of the mean concentrations of N-NO3- and 0.38 and 0.31 for the logarithm of the mean concentrations of P-PO43-. Higher r-squared were not expected due to the broad physico-chemical ranges and the low diversity of genuine aquatic bryophytes. The predicted values of the mean concentrations of N-NH4+, P-PO43- and of the standard deviation of temperatures were often greater than the measured ones. The aquatic bryophytes integrate the sudden increase of the trophic level in oligotrophic streams during the floods of the main eutrophic river and testify to a higher trophic level than expected from regular physico-chemical analyses outside the flood period. Aquatic bryophytes are also affected by water quality in the long term and indicate pollutants other than those measured in current water quality. Other factors besides trophic level might influence the aquatic bryophyte assemblages and should be monitored in order to find the precise relationships between water quality and aquatic macrophytes and in order to create a more accurate model of the effects of the flooding of disconnected streams by the Rhine waters (currently in progress in the Upper Rhine) on the aquatic macrophyte assemblages.
