La créativité des professionnels à l’épreuve du transgénérationnel dans les institutions
Authors: Corre Cécile , Bittolo Christophe 
Published: January 2018

Comment penser les notions de transmission inter- et transgénérationnelle en institution… pour pouvoir en repérer les effets positifs et négatifs sur la créativité des professionnels ? Qu’est-ce qui, dans une institution, favorise ou au contraire fait obstacle à la créativité d’une équipe dans la mise en œuvre de ses dispositifs de travail ? Ce texte se propose d’explorer comment des aspects transgénérationnels anti-créatifs concourent à la formation d’incorporats institutionnels : deux formes de rigidification sont distinguées, l’une dans le rapport à la théorie et/ou dans les échanges au sein de l’équipe et l’autre dans les dispositifs. Ces obstacles à la créativité sont mis en lien avec une problématique transgénérationnelle présente dans les fondations et avec la transmission d’un trauma non élaboré. Les auteurs interrogent, pour conclure, les qualités potentielles d’un espace d’élaboration de ces obstacles transgénérationnels.

Published: January 2018

Cet article se situe dans le champ d’étude sur les groupes à médiation thérapeutique d’inspiration analytique et se propose de traiter la question importante des conséquences dans un groupe du dysfonctionnement du cadre sur les processus psychiques et thérapeutiques attendus. Que se passe-t-il lorsque le déroulement d’un groupe à médiation thérapeutique – son cadre, ses règles – est modifié, ajusté, transformé, voire détourné ou perverti ? Que se passe-t-il lorsque le non-processus se « déguise » en processus ou devient lui-même processus ? À partir de l’analyse d’une impasse concernant un groupe à médiation Photolangage® en milieu institutionnel, la présente contribution aborde la question de l’impact de ces variations imprévues du dispositif et des perturbations conséquentes dans les fonctions contenante et conteneur , fondamentales pour le bon déroulement du groupe et du processus thérapeutique.
À propos de quelques enjeux cliniques dans la consultation thérapeutique avec des parents stériles adoptants... et leur enfant
Authors: Boutinaud Jérôme 
Published: January 2018

L’article propose une réflexion clinique à partir de l’expérience de la consultation thérapeutique auprès de parents adoptifs et de leur enfant. Se fondant sur deux récits de ces rencontres, l’auteur remet en question le sens de la rupture de chacun de ces suivis en s’interrogeant sur ce qui a pu dans son positionnement participer à leur échec. L’analyse du contretransfert montre ici que plusieurs enjeux fantasmatiques liés non seulement à l’adoption mais aussi à la stérilité des parents ont pu contribuer à provoquer ces effets et à fragiliser l’alliance thérapeutique : il apparaît dès lors que le clinicien doit se méfier des projections et fantasmes qui peuvent le traverser, ces derniers pouvant avoir trait à sa propre curiosité sexuelle vis-à-vis de la sexualité de ces parents, à la tentation d’évaluer de façon toute-puissante leurs compétences en termes de parentalité, voire de leur prêter des intentions latentes malveillantes au cœur de la procédure d’adoption...
Can land degradation drive differences in the C exchange of two similar semiarid ecosystems?

Published: January 2018

Abstract. Currently, drylands occupy more than one-third of the global terrestrial
surface and are recognized as areas vulnerable to land degradation. The
concept of land degradation stems from the loss of an ecosystem's biological
productivity due to long-term loss of natural vegetation or depletion of
soil nutrients. Drylands' key role in the global carbon (C)
balance has been recently demonstrated, but the effects of land
degradation on C sequestration by these ecosystems still need to be
investigated. In the present study, we compared net C and water vapor
fluxes, together with satellite, meteorological and vadose zone (CO2,
water content and temperature) measurements, between two nearby
(∼ 23 km) experimental sites representing “natural”
(i.e., site of reference) and “degraded” grazed semiarid grasslands. We utilized
data acquired over 6 years from two eddy covariance stations located in southeastern Spain
with highly variable precipitation magnitude and distribution.
Results show a striking difference in the annual C balances with an average
net CO2 exchange of 196 ± 40 (C release) and −23 ± 2 g C m−2 yr−1
(C fixation) for the degraded and natural sites,
respectively. At the seasonal scale, differing patterns in net CO2
fluxes were detected over both growing and dry seasons. As expected, during
the growing seasons, greater net C uptake over longer periods was observed at
the natural site. However, a much greater net C release, probably derived
from subterranean ventilation, was measured at the degraded site during
drought periods. After subtracting the nonbiological CO2 flux from net
CO2 exchange, flux partitioning results point out that, during the 6
years of study, gross primary production, ecosystem respiration and water use
efficiency were, on average, 9, 2 and 10 times higher, respectively,
at the natural site versus the degraded site. We also tested
differences in all monitored meteorological and soil variables and CO2
at 1.50 m belowground was the variable showing the greatest intersite
difference, with ∼ 1000 ppm higher at the degraded site.
Thus, we believe that subterranean ventilation of this vadose zone CO2,
previously observed at both sites, partly drives the differences in C
dynamics between them, especially during the dry season. It may be due to enhanced
subsoil–atmosphere interconnectivity at the degraded site.

Published: January 2018

Abstract
The scope of the experiments included analysis of the antimicrobial activity of ethanolic, methanolic and aqueous extracts against bacterial and fungal cultures and determination of the minimum inhibitory concentration of plant extracts tested microbial growth. Analysis of the antifungal and antibacterial activity was carried out by the disc diffusion method using paper discs. In the experiment 11 species of microorganisms – 8 bacterial and 3 fungal strains were used. The highest antimicrobial activity against the tested strains was demonstrated by black elder (Sambucus nigra L.), black locust (Robinia pseudoacacia L.) and lingonberry (Vaccinium vitis-idaea L.) extracts. The study showed the diverse morphological activity of specific parts of elderberry and quince, which is the effect of different polyphenolic profile of these plants. The yeast Saccharomyces cerevisiae, Escherichia coli, Pseudomonas putida and Bacillus subtilis showed the highest sensitivity to the effect of extracts of the analysed plants. As a positive control three antibiotics – amphotericin B, vancomycin and amoxicillin with clavulanic acid were used.

Published: January 2018

Abstract

Agaricus bisporus plays an important role in ecological processes and is one of the most widely cultivated mushrooms worldwide. Mushroom growth-promoting bacteria have been isolated from casing soil and compost, but microorganisms in the fruiting body have received only a little attention. To get an overview of phylogenetic diversity of microorganisms in the fruiting body of A. bisporus, as well as to screen antimicrobial and mushroom growth-promoting strains, and eventually intensify mushroom production, we isolated and characterized microorganisms from the fruiting body of A. bisporus. In total, 55 bacterial strains were isolated, among which nine isolates represented Actinomycetes. All the isolates were analyzed by 16S rRNA gene RFLP and sixteen representative strains by 16S rRNA gene sequencing. According to the phylogenetic analysis, eleven isolates represented the Gram-positive Bacillus, Lysinibacillus, Paenibacillus, Pandorea and Streptomyces genera, and five isolates belonged to the Gram-negative Alcaligenes and Pseudomonas genera. The bacteria isolated from the fruiting body of A. bisporus had broad-spectrum antimicrobial activities and potential mushroom growth-promoting abilities.

Abstract
The aim of our studies was to invent a reliable method for detection of the bactericidal activity of disinfectants against Borrelia burgdorferi in suspension (in vitro) and in cell line cultures (in vivo). In the suspension method, 0.01% octenidine at 20°C and 35°C was bactericidal to Borrelia afzeli; Borrelia garini, B. burgdorferi sensu stricto after 5 minutes treatment. Increase of the temperature to 35°C speed up the bactericidal effect to 1 minute. The bactericidal action of octenidine towards B. burgdorferi spirochetes growing in fibroblasts was less effective and needed a longer time to kill them than in the suspension.

Abstract
Retrospective analysis of Streptococcus agalactiae antibiotic susceptibility isolated in 2010–2013 was performed. Penicillin was still the firstline antibiotic. Due to the high percentage of strains resistant to erythromycin and clindamycin empirical treatment with these antibiotics may not be effective. Lower resistance rate to erythromycin and clindamycin among strains isolated from infected pregnant women and newborns were observed than among strains isolated from samples from patients hospitalized in other departments (29% and 47% v. 46% and 63%). The increasing resistance rate might give a rise to a new epidemiological situation.
