Septic shock is characterized by dysregulation of the host response to infection, with circulatory, cellular, and metabolic abnormalities. We hypothesized that therapy hydrocortisone plus fludrocortisone or drotrecogin alfa (activated), which can modulate response, would improve clinical outcomes patients septic shock.
Abstract: The first record of the Early Toarcian Oceanic Anoxic Event ( c . 183 Ma) from Southern Hemisphere is described Neuquén Basin, Argentina, identified chemostratigraphically on basis a relative increase in marine organic carbon and characteristic negative carbon-isotope excursion (δ 13 C org ) bulk rock fossil wood. −6‰ (falling to −31.3‰) crosses boundary tenuicostatum – hoelderi Andean ammonite Zones, equivalent falciferum / serpentinum zones Europe. These data indicate that was...
Abstract Since the last glacial maximum, soil formation related to ice‐cover shrinkage has been one major sink of carbon accumulating as organic matter (SOM), a phenomenon accelerated by ongoing global warming. In recently deglacierized forelands, processes SOM accumulation, including those that control and nitrogen sequestration rates biogeochemical stability newly sequestered carbon, remain poorly understood. Here, we investigate build‐up during initial stages (up 410 years) topsoil...

Soil carbon dynamics is strongly controlled by depth globally, with increasingly slow found at depth. The mechanistic basis remains however controversial, limiting our ability to predict cycle-climate feedbacks. Here we combine radiocarbon and thermal analyses long-term incubations in absence/presence of continuously 13C/14C-labelled plants show that bioenergetic constraints decomposers consistently drive the depth-dependency soil over a range mineral reactivity contexts. subsoil tightly...
The ELDORA/ASTRAIA (Electra Doppler Radar/Analyese Stereoscopic par Impulsions Aeroporte) airborne weather radar was recently placed in service by the National Center for Atmospheric Research and Centre d'étude des Environnements Terrestre et Planetaires France. After a multiyear development effort, saw its first field tests TOGA COARE (Tropical Oceans–Global Atmosphere Coupled Ocean–Atmosphere Response Experiment) program during January February 1993. (herein referred to as ELDORA) is...
Abstract The Toarcian oceanic anoxic event ( ca 183 Ma) coincides with a global perturbation marked by enhanced organic carbon burial and general decrease in calcium carbonate production, probably triggered changes the composition of marine plankton elevated dioxide levels atmosphere. This study is based on high‐resolution sampling two stratigraphic successions, located Valdorbia (Umbria–Marche Apennines) Monte Mangart (Julian Alps), Italy, which represent expressions deep‐water pelagic...
The Toarcian oceanic anoxic event (T-OAE) is recorded by the presence of globally distributed marine organic carbon–rich black shales and a negative carbon isotope shift, with δ13Corg values as low −33‰, interrupting an overarching positive excursion. Here we present new biostratigraphic data high-resolution from two Southern Hemisphere localities: Arroyo Serrucho in north Lapa south Neuquén Basin, Argentina. Previous studies at these localities aimed to provide accurate numerical age for...
Soil organic carbon (SOC) content is the most widely used soil health indicator, but many functions are also influenced by quality of SOC. Yet, standardized SOC parameters that can be in assessments addition to still development. Here, we investigated relationships between various (both quantity and quality) functions. We collected 223 samples from arable fields two contrasting Dutch types i.e., marine clay sand. For each sample, assessed three (i.e., biological population regulation,...
