evaluated for their effect on reactive oxygen species (ROS) generation

treatments are available. Nonsense mutations can be corrected by
molecules with nonsense mutation readthrough activity. An extract
of the mushroom Lepista inversa has recently shown high-efficiency
correction of UGA and UAA nonsense mutations. One active constituent
of this extract is 2,6-diaminopurine (DAP). In Calu-6 cancer cells,
in which TP53 gene has a UGA nonsense mutation, DAP treatment increases
p53 level. It also decreases the growth of tumors arising from Calu-6
cells injected into immunodeficient nude mice. DAP acts by interfering
with the activity of a tRNA-specific 2-O-methyltransferase (FTSJ1)
responsible for cytosine 34 modification in tRNA(Trp). Low-toxicity
and high-efficiency UGA nonsense mutation correction make DAP a good
candidate for the development of treatments for genetic diseases caused by nonsense mutations. p id=Par Nonsense mutations can be
corrected by several molecules that activate readthrough of premature
termination codon. Here, the authors report that 2,6-diaminopurine
efficiently corrects UGA nonsense mutations with no significant toxicity.},

Nonsense mutations cause about 10% of genetic disease cases, and no
treatments are available. Nonsense mutations can be corrected by
molecules with nonsense mutation readthrough activity. An extract
of the mushroom Lepista inversa has recently shown high-efficiency
correction of UGA and UAA nonsense mutations. One active constituent
of this extract is 2,6-diaminopurine (DAP). In Calu-6 cancer cells,
in which TP53 gene has a UGA nonsense mutation, DAP treatment increases
p53 level. It also decreases the growth of tumors arising from Calu-6
cells injected into immunodeficient nude mice. DAP acts by interfering
with the activity of a tRNA-specific 2-O-methyltransferase (FTSJ1)
responsible for cytosine 34 modification in tRNA(Trp). Low-toxicity
and high-efficiency UGA nonsense mutation correction make DAP a good
candidate for the development of treatments for genetic diseases caused by nonsense mutations. p id=Par Nonsense mutations can be
corrected by several molecules that activate readthrough of premature
termination codon. Here, the authors report that 2,6-diaminopurine
efficiently corrects UGA nonsense mutations with no significant toxicity. |

the addition of a layer material to the soil surface) and their efficiency
to promote recolonization by pedofauna of isolated and degraded areas.
The experimental study was set up in the former coal mining area
of Northern France. This area is particularly disturbed and fragmented
by land-use change, urbanization, industry, intensive agriculture
and metal pollution. To examine the movements of pedofauna, four
kinds of mulches were applied: (i) Ramial Chipped Wood (RCW), (ii)
chopped Miscanthus, (iii) dead leaves and (iv) wheat straw as well
as plastic sheeting, a material often used in green spaces. A negative
control consisted in soil without mulch addition. The experimental
set-up consisted of a set of 18 bands of mulch (6 m long x 0.5 m
width x 8 cm thick, i.e. a volume of 0.04 m3 per band) installed
on three adjacent plots on a surface area which stretch on 4400 m2:
(i) plot F1, a mixed plantation, (ii) plot M consisted of three rows
of maples (both considered to be the reservoir of biodiversity) and
(iii) plot BF, an ash plantation (with lower biodiversity). Faunistic
communities of soil present within the mulches were monitoring using
pitfall traps for four months (April to July), at a rate of eight
surveys for each of the 90 traps installed, i.e. 720 samples. Different
life traits and indices of diversity were studied, more specifically
on carabid beetles. The main objective of the study was first to
check whether mulches could or not reconnect different planted plots
in a peri-urban landscape highly modified by human activities. The
second aim was to find which type of mulch had the best efficiency
in the recovery of the connectivity between plots. The last questions
were which type of zoological groups could be favoured by the use
of mulches and which benefits for ecosystem functioning. The main
hypotheses of this study were: (i) Organic mulches would act as dispersal
corridors and refuge zones to the soil organisms; (ii) organic mulches
would be attractive to many organisms with various ecological needs.
This study highlighted the potential benefits of using the mulching
technique to support ecological connectivity in disturbed environment
since this method highlighted the presence of individuals with different
diets (saprophagous, predators, phytophagous and so forth), small
and large size species which do not have the same dispersal capacities
as well as species that are more dependent on forest environments
and others that depend on more open environments. The study concluded
that organic mulches are more favourable to pedofauna than soil without
mulch or plastic sheeting. With regard to organic mulches, no difference
was noted, either in terms of cumulative abundance or monthly monitoring.
However, for carabids, it should be noted that dead leaves and wheat
straw have higher specific richness than Miscanthus and RCW.},

Registry data from 1 July 2011 to 21 September 2017. Female and male
survival rates at D30 were compared.
RESULTS:At baseline 66 395 OHCA victims were included, of which 34.3%

patients and 20.2% for male patients [odds ratio (OR), 1.138 (1.092-1.185)];

CONCLUSIONS:In this large nationwide matched OHCA study, female patients
had a better chance of survival with no significant difference in

La mobilisation de toutes les politiques publiques est indispensable
pour agir sur les inégalités environnementales et sociales de santé
(IESS). Le paradigme actuel décrit ces inégalités territoriales comme
une accumulation de déterminants de santé défavorables dans une zone
géographique donnée, généralement entendue comme la vulnérabilité
d’un territoire. L’absence quasi-systématique des déterminants ayant
un impact positif sur la santé dans les modèles ne permet pas d’obtenir
une vision réaliste de l’impact global de l’environnement sur la
santé des populations. L’intégration de la résilience, comme la capacité
des territoires à gérer les IESS, devient alors indispensable pour
inclure les efforts déployés pour améliorer le cadre de vie des habitants.
Validée dans la région des Hauts-de-France, l’analyse conjointe d’un
indice composite spatialisé de vulnérabilité et d’un indice composite
spatialisé de résilience permet de décrire la balance résilience/vulnérabilité
à l’échelle des communes. Cette démarche permettra in fine de mieux
caractériser les IESS, d’affiner les connaissances sur les dynamiques
territoriales en jeu et d’orienter de nouvelles réflexions en termes
de gestion politique et territoriale des risques sanitaires. |

abstract = {Although the incidence of Crohn’s disease has increased worldwide
over the past 30 years, the disorder’s exact causes and physiological
mechanisms have yet to be determined. Given that genetic determinants
alone do not explain the development of Crohn’s disease, there is
growing interest in “environmental” determinants. In medical science,
the term “environment” refers to both the ecological and social surroundings;
however, most published studies have focused on the latter. In environmental
and exposure sciences, the term “environment” mostly relates to contamination
of the biotope. There are many unanswered questions on how environmental
hazards might contribute to the pathogenesis of Crohn’s disease.
Which pollutants should be considered? Which mechanisms are involved?
And how should environmental contamination and exposure be evaluated?
The objective was to perform a systematic review of the literature
on Crohn’s disease and environmental contamination. We searched the
PubMed, Google Scholar, Scopus, ISI Web of Science and Prospero databases.
We considered all field studies previous to April 2019 conducted
on human health indicators, and evaluating exposure to all type of
physical, biological and chemical contamination of the environment.
The lack of clear answers to date can be ascribed to the small total
number of field studies (n ¼ 16 of 39 publications, most of which
were conducted by pioneering medical scientists), methodological
differences, and the small number of contaminants evaluated. This
make it impossible to conduct a coherent and efficient meta-analysis.
Based on individual analysis of available studies, we formulated
five recommendations on improving future research: (i) follow up
the currently identified leads - especially metals and endocrine
disruptors; (ii) explore soil contamination; (iii) gain a better

Although the incidence of Crohn’s disease has increased worldwide
over the past 30 years, the disorder’s exact causes and physiological
mechanisms have yet to be determined. Given that genetic determinants
alone do not explain the development of Crohn’s disease, there is
growing interest in “environmental” determinants. In medical science,
the term “environment” refers to both the ecological and social surroundings;
however, most published studies have focused on the latter. In environmental
and exposure sciences, the term “environment” mostly relates to contamination
of the biotope. There are many unanswered questions on how environmental
hazards might contribute to the pathogenesis of Crohn’s disease.
Which pollutants should be considered? Which mechanisms are involved?
And how should environmental contamination and exposure be evaluated?
The objective was to perform a systematic review of the literature
on Crohn’s disease and environmental contamination. We searched the
PubMed, Google Scholar, Scopus, ISI Web of Science and Prospero databases.
We considered all field studies previous to April 2019 conducted
on human health indicators, and evaluating exposure to all type of
physical, biological and chemical contamination of the environment.
The lack of clear answers to date can be ascribed to the small total
number of field studies (n ¼ 16 of 39 publications, most of which
were conducted by pioneering medical scientists), methodological
differences, and the small number of contaminants evaluated. This
make it impossible to conduct a coherent and efficient meta-analysis.
Based on individual analysis of available studies, we formulated
five recommendations on improving future research: (i) follow up
the currently identified leads - especially metals and endocrine
disruptors; (ii) explore soil contamination; (iii) gain a better
knowledge of exposure mechanisms by developing transdisciplinary
studies; (iv) identify the most plausible contaminants by developing
approaches based on the source-to-target distance; and (v) develop
registries and cohort-based analyses |

effects of cadmium (Cd) and lead (Pb) in Brassica oleracea and Trifolium
repens. In addition to morphological parameters, this work also used
comet assay to address endpoints in relation to genotoxicity. Bioaccumulation
was measured to demonstrate the influence of the mixture on the concentrations
of each metal in the plant.
The statistical method reported by Ince et al. (1999) was used to
evaluate the types of interaction between Cd and Pb in each treatment
and concerning their combined effect.
This study concludes that the combined effects of binary metal combinations
of Cd/Pb on morphological parameters are most often additive, sometimes
antagonistic and more rarely synergistic, thus extending the findings
of previous publications on this subject.
DNA damage analysis revealed concentration- and time-dependent interactions.
Synergistic effects of mixed metals (more breaks than individually
applied metals) are observed in T. repens after a short exposure.
Antagonistic effects are statistically significant after 10 days-exposure,
suggesting competition between metals. At 56 days, the rate of DNA
damage observed in plants exposed to the Cd/Pb mixture was similar
to that measured in plants exposed to lead only and was significantly
lower than the rate of DNA damage induced by Cd. This supports the
idea that there may be competition between metals and also strengthens
the hypothesis that long-term reparation mechanisms may be implemented.
Cd/Pb co-exposure does not significantly influence the bioaccumulation
of each metal. It is nevertheless important to note that a statistically
significant ‘interaction’ is not necessarily biologically relevant
and should therefore be considered with caution when assessing heavy
metals combined effects},

results showed that the two studied fly ashes Soproline® and Sodeline®

of metals, nearly 14 years after amendment. Regarding biological
parameters, no positive or negative effects were found by adding
fly ashes to the soil concerning soil basal respiration and urease
activity. The fungal activity was even enhanced. In the same way,
the fly ashes had no negative effect on the Diptera larvae community
and a greater richness of larvae was even found in amended soils.

fly ashes should be an advantageous technique to manage metal-polluted
soils and to recycle industrial wastes.},
