Carex divisa is a patrimonial rhizomatous species and acts as an important component of grazed wet permanent grassland on the French Atlantic coast. This study treated three storage regimes (wet-cold, dry-cold and dry-warm), burial in soil, fluctuating temperature and salinity on seed germination of C. divisa. The seeds were dormant at maturity. No seed germinated after 2 and 6 weeks of dry sto...

OBJECTIVE A significant metabolic derangement occurs in the ischaemic-reperfused heart of patients undergoing coronary artery bypass surgery using cold blood cardioplegia. The aim of the present study was to investigate whether this effect could be reversed by complementing cold blood cardioplegia with a short terminal exposure of warm blood hyperkalaemic cardioplegia ('hot shot'). METHODS Th...

and Introduction: A synthesis of a diverse suite of observations of H2O-related landforms that are possible Mars analogs from terrestrial polar regions (Devon Island in the Arctic; the Dry Va lleys of Antarctica) put into question any requirement for extended episode(s) of warm and wet climate in Mars’s past. Geologically transient episodes of localized H2O cycling, forced by exogenic impacts, ...

Identification of ionotropic receptors required for hygrosensation in Drosophila supports the notion that hygrosensory neurons across insects share common morphological and anatomical features. This further advances the field by uncovering central circuits that respond to both humidity and temperature.

Water on Mars has been explained by invoking controversial and mutually exclusive solutions based on warming the atmosphere with greenhouse gases (the ‘‘warm and wet’’ Mars) or on local thermal energy sources acting in a global freezing climate (the ‘‘cold and dry’’ Mars). Both have critical limitations and none has been definitively accepted as a compelling explanation for the presence of liqu...

INTRODUCTION In the prehospital care of a cold and wet person, early application of adequate insulation is of utmost importance to reduce cold stress, limit body core cooling, and prevent deterioration of the patient's condition. Most prehospital guidelines on protection against cold recommend the removal of wet clothing prior to insulation, and some also recommend the use of a waterproof vapor...

Acutely decompensated heart failure (ADHF) is characterized by hemodynamic abnormalities and neurohormonal activation that contribute to heart failure (HF) symptoms, end-organ dysfunction, arrhythmias, and progressive cardiac failure. The management of ADHF in the emergency department (ED) can be simplified and improved by a 2-min bedside assessment that identifies any of four possible hemodyna...

Although the ability to sense skin wetness and humidity is critical for behavioral and autonomic adaptations, humans are not provided with specific skin receptors for sensing wetness. It has been proposed that we "learn" to perceive the wetness experienced when the skin is in contact with a wet surface or when sweat is produced through a multisensory integration of thermal and tactile inputs ge...
