précocesAbstractIntroduction. – Teenage pregnancy arouses lots of questions and remains a worldwide social and public health problem. This phenomenon isproblematic because it is often associated with socio-economic, family and psychological difficulties.Objective. – Our study aims to identify the individual and environmental factors that influence the teenager’s decision whether to keep her child ornot.Method. – A sample of fourteen girls between 16 and 21 years old was recruited who had been or were pregnant. The girls were divided into2 groups: seven who decided to continue with their pregnancy and seven others who decided to have an abortion. This group was compared to girlswho had never been pregnant (n = 18). An interview was carried out and structured questionnaires were administered in order to evaluate individualand environmental characteristics as the age of menarche and the first sexual intercourse, the emotional and sexual education, the social and family support, the socio-cultural background and the socio-economic environment. Different other dimensions were analyzed: individual characteristics(Temperament and Character Inventory Junior, Impulsive Behaviour Scale, Coopersmith Self-Esteem Inventory) and family characteristics (AdverseChildhood Experiences) such as childhood family strengths and adverse childhood experiences.Results and conclusions. – Our study findings showed that a precarious socio-economic environment, a lack of support and affection in thefamily, emotional deprivations, a restricted social network, low self-esteem and school disinvestments would effectively predict the continuationof a pregnancy. Childhood family strengths seem to be strongly protective against early sexual intercourse, adolescent pregnancy and long-termpsychosocial consequences. On the other hand, no particular personality feature was demonstrated. Individual characteristics would thus have lessimpact on premature pregnancies than environmental characteristics. Prevention programs must stretch beyond the use of contraception, i.e. tendtoward an intervention for psycho-socially and socio-economically at risk families, so as to support them in their educational and affective rolewith their children. Psychological help could also be brought to young girls who have had experiences of maltreatment, to favour self-esteem andraise their awareness of the consequences of sexual risk behaviour. Finally, there should be specific help for the girls during the decision-makingperiod. Counselling during this period should be attentive to the resources and the motivations of the adolescent and to the circumstances of the pregnancy. [less ▲]

False memories induced by the DRM procedure (“Deese, Roediger and McDermott”; Deese, 1959; Roediger & McDermott, 1995) or the misinformation procedure (in which a person’s recollection of a witnessed event is altered after exposure to misinformation about this event; Loftus et al., 1978) are due to errors in source monitoring processes (e.g., Johnson et al., 1993) and one might expect the correlation between these false memories quite positive. However, the few laboratory studies comparing the DRM paradigm and the misinformation paradigm show small (Zhu et al., 2013) or no correlation (Ost et al., 2013) between the false memories elicited by these procedures but these studies vary in terms of methodological details. For instance, false memories from the misinformation procedure involved emotional content while those from the DRM procedure only included neutral materials. This study investigated the relationship between false memories induced by two different paradigms (a DRM task and a misinformation procedure) both involving an emotional material. Participants (N = 154) completed an emotional variant of the DRM (neutral, positive and negative lists) and the misinformation (neutral, positive and negative images) procedures and their performances on both tasks were compared. Although both paradigms reliably induced false memories in participants, our analyses revealed only a marginally weak positive correlation (r = .147, p = .051) between misinformation and DRM false memories using emotional variants. These results support the idea that DRM and misinformation false memories are underpinned by (at least in part) different mechanisms and that the previous mixed results were not due to the specific content of the DRM or the misinformation task used.

Medical diagnosis and biotechnology progresses are strongly dependent on the development of sensing devices, which, ideally, would allow the reliable detection of very low amounts of biological species in various environments. In addition to these requirements, the detection tools would also be easy to use and would rapidly response. Fluorescent based biosensors fulfil most of these characteristics. In our work, the intersection between two crossed optical fibers is used as the basic unit of an original optical biosensor. As illustrated by figure 1, one optical fiber is used to carry probe molecules and excite fluorescence while the second one is devoted to carry the target species and collect the optical signal arising from the species interacting at the node. The advantages of our set-up over traditional optical sensors are no surface functionalization, use of low amounts of biological species, limitation of the denaturation risk, ease to use and low detection threshold. The developed biosensor is validated on two systems. The first one is a fluorescent calcium indicator, Oregon green 488 BAPTA-2, whose optical emission signal is affected by Ca2+ ions concentration. The second one is based on Rh-Con A and FITC-Dextran complex for which the FRET phenomenon is affected by glucose concentration. In both cases, the results are in agreement with the ones obtained in cuvettes attesting the efficiency of the sensing device. We also show a prototype of a multichannel device composed of multiple crossed optical fibers which are used as species and light carriers. [less ▲]

Discrete Abelian symmetries (ZN) are a common “artifact” of beyond the standard model physics models. They provide different avenues for constructing consistent scenarios for lepton and quark mixing patterns, radiative neutrino mass generation as well as dark matter stabilization. We argue that these symmetries can arise from the spontaneous breaking of the Abelian U(1) factors contained in the global flavor symmetry transformations of the gauge-invariant kinetic Lagrangian. This will be the case provided the ultraviolet completion responsible for the Yukawa structure involves scalar fields carrying nontrivial U(1) charges. Guided by minimality criteria, we demonstrate the viability of this approach with two examples: first, we derive the “scotogenic” model Lagrangian, and second, we construct a setup where the spontaneous symmetry-breaking pattern leads to a Z3 symmetry which enables dark matter stability as well as neutrino mass generation at the two-loop order. This generic approach can be used to derive many other models, with residual ZN or ZN1×⋯×ZNk symmetries, establishing an intriguing link between flavor symmetries, neutrino masses and dark matter.

Objectives: The restorative properties of platelets, through the local release of growth factors, are used in various medical areas. This article reviews fundamental and clinical research relating to platelet-rich plasma applied to tendinous lesions. Materials and method: Articles in French and English, published between 1 January 2012 and 31 December 2014 dealing with PRP and tendons were searched for using the Medline and Scopus data bases. Results: Forty-seven articles were identified which addressed pre-clinical and clinical studies: 27 relating to in vitro and in vivo animal studies and 20 relating to human studies. Of these, five addressed lateral epicondylitis, two addressed rotator cuff tendinopathies, ten dealt with patellar tendinopathies and three looked at Achilles tendinopathies. Conclusions: The majority of pre-clinical studies show that PRP stimulates the tendon's healing process. However, clinical series remain more controversial and level 1, controlled, randomised studies are still needed. [less ▲]

The aquatic environment represents the final sink for many chemicals, including bactericidal agents. Among them Triclosan (TCS) has been shown to affect the thyroid system of teleost. Larval stages are particularly vulnerable to deleterious effects of endocrine disrupters because of potential impairment of fish development and behaviour. Thyroid hormones are critical to the development of the brain and auditory system. Thus, TCS could affect the development of the brain and hearing. The aims of this study were: to investigate hearing development in sheepshead minnows (Cyprinodon variegatus) using the ABR technique (Auditory Brainstem Response) and to investigate the effects of triclosan on hearing development. Exposure to TCS was conducted from fertilization of eggs on at concentrations likely to be found in the environment: 20, 50 and 100 μgl-1. We characterized previously the ontogenic variation of thyroid hormones in embryos and larvae of sheepshead minnows. We observed an increase of thyroid hormones level around the 12th and the 15th day post hatching (dph), that may be associated with the transition from larval to juvenile stage during the development of this species. We concluded, that this period could be defined as a critical exposure window to pollutants. We determined hearing thresholds for sheepshead minnows of different ages. Due to the small size of larvae, first measurements were only possible at 30 dph. Audiograms showed that the hearing ability is not yet completely established at 30 dph compared to adults. So we pursued our experiments in older larvae of 40, 60, 70, and 80 dph when sexual maturity is attained. First results indicate that the hearing ability considerably improves between 50 and 60 dph. The effects of TCS in this development have yet to be determined but will be fully discussed. This study proposes an interesting new endpoint in thyroid disruption research. [less ▲]
