Relations between suicidal behaviours and menstrual cycle have been studied by various authors with different methodologies, from which miscellaneous and contradictory results. We have taken this relation again, about suicide attempts admitted in Dijon's emergency department. Were recorded for each suicidal woman aged 15 to 49 their sociodemographical and(More)
Nitric oxide (NO) is a free radical gas involved in a myriad of plant physiological processes including immune responses. How NO mediates its biological effects in plant facing microbial pathogen attack is an unresolved question. Insights into the molecular mechanisms by which it propagates signals reveal the contribution of this simple gas in complex(More)
Calcium and nitric oxide (NO) are two important biological messengers. Increasing evidence indicates that Ca(2+) and NO work together in mediating responses to pathogenic microorganisms and microbe-associated molecular patterns. Ca(2+) fluxes were recognized to account for NO production, whereas evidence gathered from a number of studies highlights that NO(More)
β-Aminobutyric acid (BABA) is a nonprotein amino acid inducing resistance in many different plant species against a wide range of abiotic and biotic stresses. Nevertheless, how BABA primes plant natural defense reactions remains poorly understood. Based on its structure, we hypothesized and confirmed that BABA is able to chelate iron (Fe) in vitro. In vivo,(More)
Pyoverdines are siderophores synthesized by fluorescent Pseudomonas spp. Under iron-limiting conditions, these high-affinity ferric iron chelators are excreted by bacteria in the soil to acquire iron. Pyoverdines produced by beneficial Pseudomonas spp. ameliorate plant growth. Here, we investigate the physiological incidence and mode of action of pyoverdine(More)
Four patients who developed acute myeloblastic leukemia during the treatment of a non-Hodgkin's lymphoma are described. In three cases the same sequence was observed: a favorable histological type of lymphoma, an apparently complete and lasting remission, a long period of tri-cytopenia, and finally acute myeloid leukemia. The fourth patient had a(More)
