The isohydric strategy of Platanus × hispanica tree shapes its response to drought in an urban environment.

Urban vegetation provides many ecosystem services like heat island mitigation. However, urban trees are subjected to the stresses that they are meant to alleviate, with drought being a main constraint. We investigated the drought response strategy of plane trees (Platanus × hispanica), focusing on stomatal regulation and metabolic remodelling.

Development and evaluation of the accuracy of an indicator of the appropriateness of interventional cardiology generated from a French registry.

Background: Development of appropriateness indicators of medical interventions has become a major quality-of-care issue, especially in the domain of interventional cardiology (IC). The objective of this study was to develop and evaluate the accuracy of an indicator of the appropriateness of interventional cardiology acts (invasive coronary angiographies (ICA) and percutaneous coronary interventions (PCI)) in patients with coronary stable disease and silent ischemia, automated from a French registry.

Methods: All ICA and PCI recorded in a Regional IC Registry (ACIRA) and operated for a stable coronary artery disease or silent ischemia from January 1st to December 31th 2013 in eight IC hospitals of Aquitaine, southwestern France, were included.

In-Depth Proteomic Analysis of the Secondary Dormancy Induction by Hypoxia or High Temperature in Barley Grains.

In barley, incubation of primary dormant (D1) grains on water under conditions that do not allow germination, i.e. 30°C in air and 15°C or 30°C in 5% O2, induces a secondary dormancy (D2) expressed as a loss of the ability to germinate at 15°C in air.

Potential involvement of proline and flavonols in plant responses to ozone.

Ozone is considered to be a major phytotoxic pollutant. It is an oxidizing molecule with harmful effects that can affect human health and vegetation. Due to its phytotoxicity, it constitutes a threat to food security in a context of climate change.
