National population-based retrospective cohort study. The French National Health Insurance Database that includes hospital discharge data and health claims data. Singleton pregnancies (2012-2014) with a live birth occurring after 22WG from women between 15 and 45years old and insured the year before the first day of gestation and during pregnancy were included. We excluded pregnancies for which anti-inflammatory medications were dispensed after 22WG. The association between exposure and risk of preterm birth was evaluated with GEE models, adjusting on a large number of covariables, socio-demographic variables, maternal comorbidities, prescription drugs and pregnancy complications. Prematurity, defined as a birth that occurred before 37WG. Among our 1598330 singleton pregnancies, early exposure to non-selective NSth increased risk of prematurity.The free radical nitric oxide (NO) and the phenolic phytohormone salicylic acid (SA) are signal molecules which exert key functions at biochemical and physiological levels. Abiotic stresses, especially in early plant development, impose the biggest threats to agricultural systems and crop yield. These stresses impair plant growth and subsequently cause a reduction in root development, affecting nutrient uptake and crop productivity. The molecules NO and SA have been identified as robust tools for efficiently mitigating the negative effects of abiotic stress in plants. SA is engaged in an array of tasks under adverse environmental situations. The function of NO depends on its cellular concentration; at a low level, it acts as a signal molecule, while at a high level, it triggers nitro-oxidative stress. The crosstalk between NO and SA involving different signalling molecules and regulatory facto
