Twenty years of irrigation acclimation is driven by denser canopies and not by plasticity in twig- and needle-level hydraulics in a Pinus sylvestris forest

Charlotte Grossiord, Christoph Bachofen, Eugénie Isabelle Mas, Hervé Cochard, Alice Jacqueline Frédérique Gauthey, Alex Tunas Corzon

Climate change is predicted to increase atmospheric vapor pressure deficit, exacerbating soil drought, and thus enhancing tree evaporative demand and mortality. Yet, few studies have addressed the longer-term drought acclimation strategy of trees, particul ...

Water retention behaviour of compacted bentonites: experimental observations and constitutive model

Anne-Catherine Adolphine M Dieudonné

Bentonite-based materials are studied as potential barriers for the geological disposal of radioactive waste. In this context, the hydro-mechanical behaviour of the engineered barrier is first characterized by free swelling conditions followed by constant ...

Neural generators of psychogenic seizures: Evidence from intracranial and extracranial brain recordings

Olaf Blanke, Pär Halje

Psychogenic seizures (PSs) convincingly mimic seizure phenomena but with no underlying epileptic activity. However, not much is known about their neurophysiological basis. We had the rare opportunity to analyze intracranial brain recordings of PSs occurrin ...

An Innovative Technique for Water Retention Characterization of Highly Swelling Geomaterials

Lyesse Laloui, Alessio Ferrari, Ali Seiphoori

This paper presents an innovative method called Micro-cell technique to obtain the water retention curves of geomaterials particularly highly swelling clays such as MX-80 bentonite. This method is based on the controlled water content and measured suction ...

Stimulus-induced modulation of transcriptional bursting in a single mammalian gene

Felix Naef, David Michael Suter, Benjamin Zoller, Rosamaria Cannavo

Mammalian genes are often transcribed discontinuously as short bursts of RNA synthesis followed by longer silent periods. However, how these "on" and "off" transitions, together with the burst sizes, are modulated in single cells to increase gene expressio ...

Metabolic Labeling and Protein Linearization Technology Allow the Study of Proteins Secreted by Cultured Cells in Serum-Containing Media

Supernatants from cell cultures (also called conditioned media, CMs) are commonly analyzed to study the pool of secreted proteins (secretome). To reduce the exogenous protein background, serum-free media are often used to obtain CMs. Serum deprivation, how ...

Differences in corticosterone level due to inter-food interval length: implications for schedule-induced polydipsia

Maria del Carmen Sandi Perez

The purpose of this study was to determine the effects of different food-reinforcement schedules on plasma corticosterone (CORT), and its possible involvement in the acquisition and maintenance of schedule-induced polydipsia (SIP). In Experiment 1, three g ...

The 4.5 angstrom structure of human AQP2

Henning Paul-Julius Stahlberg, Andreas Engel

Located in the principal cells of the collecting duct, aquaporin-2 (AQP2) is responsible for the regulated water reabsorbtion in the kidney and is indispensable for the maintenance of body water balance. Disregulation or malfunctioning of AQP2 can lead to ...

Vasopressin type 1A receptor up-regulation by cyclosporin A in vascular smooth muscle cells is mediated by superoxide

Based on our previous results, we investigated whether cyclosporin A (CsA)-induced vasopressin type 1A receptor up-regulation was mediated by free radicals. We report that CsA analogues with different affinities for cyclophilin and calcineurin were able to ...
