Background: Long-term exposure to persistent pollutants with hormonal properties (endocrine-disrupting chemicals, EDCs) may contribute to the risk of prostate cancer (PCa). However, epidemiological evidence remains limited. Objectives: We investigated the relationship between PCa and plasma concentrations of universally widespread pollutants, in particular p,p’- dichlorodiphenyl dichloroethene (DDE) and the non-dioxin like polychlorinated biphenyl congener 153 (PCB153). Methods and Findings: We evaluated before treatment 576 men with newly diagnosed PCa and 655 controls in Guadeloupe (French West Indies). Exposure was analyzed according to case-control status. Associations were assessed by unconditional logistic regression analysis, controlling for confounding factors. Missing data were handled by multiple imputation. We estimated a significant positive association between DDE and PCa (adjusted odds ratio [OR] 1.53; 95% CI 1.02, 2.30 for the highest versus lowest quintile of exposure; PTrend= 0.01). PCB153 was inversely associated with PCa (OR 0.30; 95% CI 0.19, 0.47 for the highest versus lowest quintile of exposure values; PTrend<0.001). Also, PCB153 was more strongly associated to low-grade than high grade PCa. Conclusions: Associations of PCa with DDE and PCB153 were in opposite directions. This may reflect differences in the mechanisms of action of these EDCs, and although our findings need to be replicated in other populations, they are consistent with complex effects of EDCs on human health.

Increasing plant diversity within crops can be beneficial for pest control. In this field study, the effects of two wheat and pea associations (mixed cropping and strip cropping) on aphid populations were compared with pure stands of both crops by observations on tillers and plants. Pea was more susceptible to infestations than wheat. As expected, the density of aphid colonies was significantly higher in pure stands during the main occurrence periods, compared with associations. Additionally, flying beneficials, such as not only aphidophagous adult ladybirds but also parasitoid, hoverfly and lacewing species that feed on aphids at the larval stage, were monitored using yellow pan traps. At specific times of the sampling season, ladybirds and hoverflies were significantly more abundant in the pure stand of pea and wheat, respectively, compared with associations. Few parasitoids and lacewings were trapped. This study showed that increasing plant diversity within crops by associating cultivated species can reduce aphid infestations, since host plants are more difficult to locate. However, additional methods are needed to attract more efficiently adult beneficials into wheat and pea associations. [less ▲]

Le traitement des cancers du col utérin repose sur la radiothérapie et la chirurgie. Le pronostic des formes évoluées a conduit à proposer différentes modalités d’association dont seuls les traitements concomitants ont montré un intérêt. Les associations de radiothérapie et d’un radiosensibilisant n’ont pas apporté, de bénéfice, voire abouti à des résultats inférieurs à ceux de l’irradiation exclusive. L’Hydroxyurée et la Mitomycine C ont été largement testées, seules ou en association, sans qu’elles puissent être retenues comme efficaces.

In four experiments, adherence to grammatical rules and associative chunk strength (including different measures, each calculated on the basis of the frequency with which bigrams and trigrams present in the test strings appeared in the learning strings) were manipulated independently in the test phase of an artificial grammar learning task. When participants learned few items of the grammar (Experiments 1a and 2a), the associated items were more often classified as grammatical than the nonassociated ones. On the other hand, when the learning phase included most of the grammatical items (Experiments 1b and 2b), the only effect observed was an effect of grammaticality. These results suggest that, depending on the specific constraints of the tasks, knowledge based on bigrams and trigrams and knowledge based on the abstraction of the grammatical structure can be used for the classification task.

Traditional methods of volatile detection used by police typically consist of reliance on canine olfaction. However, dogs have some limitations such as cost of training and time of conditioning. The possibility of using parasitic wasps for detecting explosives and narcotics has been developed. Moreover, wasps are cheap to produce and can be conditioned with impressive speed for a specific chemical-detection task. We examined the ability of Nasonia vitripennis Walker to learn and respond to methydisulfanylmethane (DMDS), a volatile discriminator of cadaver. The training aimed to form an association between an unconditioned stimulus (pupae) and the conditioned stimulus (odor source). After the training, the time spent of conditioned wasps in the DMDS chamber was measured. Statistical analysis showed that the increasing concentrations involved an increase in the time spent in the chamber containing DMDS. This study indicates that N. vitripennis can respond to DMDS, which provide further support for its development as a biological sensor. [less ▲]

In normal aging, memory for associations declines more than memory for individual items. Unitization is an encoding process defined by creation of a new single entity to represent a new arbitrary association. The current study tested the hypothesis that age-related differences in associative memory can be reduced following encoding instructions that promote unitization. In two experiments, groups of 20 young and 20 older participants learned new associations between a word and a background color under two conditions. In the item detail condition, they had to imagine that the item is the same color as the background; an instruction promoting unitization of the associations. In the context detail condition, that did not promote unitization, they had to imagine that the item interacted with another colored object. At test, they had to retrieve the color that was associated to each word (source memory). In both experiments, the results showed an age-related decrement in source memory performance in the context detail but not in the item detail condition. Moreover, Experiment 2 examined receiver operating characteristics in older participants and indicated that familiarity contributed more to source memory performance in the item detail than in the context detail condition. These findings suggest that unitization of new associations can overcome the associative memory deficit observed in aging, at least for item-color associations. [less ▲]

This paper aims to expand the domain of brand image perception measurement by providing a method for eliciting brand associative networks and comparing it with traditional brand image measurement methods. This paper then argues that these networks may differ from one individual to another, depending on the cultural background and/or the experience with the brand. Accordingly, the authors introduce a methodology of clustering consumers with similar perceptions into distinct segments, which can be targeted differently. Using picture analysis and metaphor-based elicitation techniques, Lipton’s Ice Tea brand associations are extracted and utilised as an input for the creation of 160 individual associative networks.These networks are first aggregated to measure the brand reputation and subsequently clustered into six segments. This paper provides clear arguments for using associative networks as the preferred method to capture the complete brand image. The paper discusses implications of perceptual segmentation for image management, brand positioning, perceptual competition analysis and brand communication. [less ▲]

It has been hypothesised that the hippocampal regions are involved specifically in the encoding of associations between different kinds of information and in the recollection process of recognition memory. We examined the performance of two severely amnesic patients (AC and MR) with different kinds of lesions on three associative (one intra-modal and two inter-modal) recognition tasks and two item recognition tasks. AC was impaired on all the tasks, whereas MR was impaired on the associative tasks but had a preserved familiarity-based recognition. Combined with the etiology and the loci of the patients’ lesions, these results support partly the hypothesis. [less ▲]

Les femmes enceintes sont conscientes que toute forme d’addiction durant leur grossesse peut être préjudiciable à leur enfant. Pourtant, de nombreuses gestantes continuent de fumer, de boire de l’alcool, de consommer des drogues illicites ou d’absorber des médicaments, car ces dépendances sont particulièrement tenaces. Le quatuor de tête en termes de préjudice fœtal est composé du tabac, de l’alcool, de la cocaïne et de l’ecstasy. La période de grossesse est le meilleur moment pour mettre fin à ces addictions. Aussi, est-il indispensable de sensibiliser le grand public, les pouvoirs politiques ainsi que les médecins sur le fait que les assuétudes durant la grossesse représentent une inégalité de santé et d’espérance de vie importante pour l’enfant à naître.

With the combination of the enhanced assumed strain (EAS) and assumed natural strain (ANS) techniques in the removal of shear and volumetric locking, the solid-shell formulation requires a minimum set of enhanced modes, and this results in a competitive approach when compared with other fully EAS solid elements in terms of computational costs. Moreover, the latter reportedly suffers difficulties when dealing with very thin plate and shell structures due to the severe transverse shear locking. The paper presents an alternative solid-shell formulation, in which the ANS technique is applied to the upper and lower surfaces instead of at the mid-surface of the solid-shell element as previously adopted. The numerical results show the accuracy and efficiency of the proposed technique. [less ▲]
