Predicted responses of transpiration to elevated atmospheric CO2 concentration (eCO2) are highly variable amongst process-based models. To better understand and constrain this variability amongst models, we conducted an intercomparison of 11 ecosystem models applied to data from two forest free-air CO2 enrichment (FACE) experiments at Duke University and Oak Ridge National Laboratory. We analysed

The quaternary phase Ca5Mg0.95Ag1.05(1)Ge5 (3) was synthesized by high-temperature solid-state techniques, and its crystal structure was determined by single-crystal diffraction methods in the orthorhombic space group Pnma - Wyckoff sequence c(12) with a = 23.1481(4) Å, b = 4.4736(1) Å, c = 11.0128(2) Å, V = 1140.43(4) Å(3), Z = 4. The crystal structure can be described as linear intergrowths of s

Molecular dynamics simulations have been performed on lipase B from Candida antarctica (CalB) in its native form and with one or two oxidized residues, either methionine oxidized to methionine sulfoxide, tryptophan oxidized to 5-hydroxytryptophan, or cystine oxidized to a pair of cysteic acid residues. We have analyzed how these oxidations affect the general structure of the protein as well as the

The recognition of carbohydrates by proteins is a fundamental aspect of communication within and between living cells. Understanding the molecular basis of carbohydrate-protein interactions is a prerequisite for the rational design of synthetic ligands. Here we report the high- to ultrahigh-resolution crystal structures of the carbohydrate recognition domain of galectin-3 (Gal3C) in the ligand-fre

In order to better address the feedbacks between climate and wetland methane (CH4) emissions, we tested several mechanistic improvements to the wetland CH4 emission model Peatland-VU with a longer Arctic data set than any other model: (1) inclusion of an improved hydrological module, (2) incorporation of a gross primary productivity (GPP) module, and (3) a more realistic soil-freezing scheme. A lo

We present comprehensive results on continuous atmospheric cluster and particle measurements in the size range similar to 1-42 nm within the European Integrated project on Aerosol Cloud Climate and Air Quality interactions (EUCAARI) project. We focused on characterizing the spatial and temporal variation of new particle formation events and relevant particle formation parameters across Europe. Dif

Cocaine- and amphetamine-regulated transcript-derived peptides (CARTp) and corticotropin-releasing factor (CRF) alter feeding and gastrointestinal function after central administration, and the gastric inhibitory effects are mediated through CRF. We hypothesized that dorsal hindbrain effects of CARTp on gastric emptying are mediated by the vagus nerve and that the dorsal vagal complex (DVC) is a s

Background: Oxidation of LDL is associated with generation of autoantibodies against a large number of different aldehyde-modified peptide sequences in apo B-100. Autoantibodies recognizing peptide sequences in the LDL receptor-binding region of apo B-100 could potentially affect both cholesterol metabolism and atherosclerosis. The aim of the present study was to determine physiological effects of

The adapter protein APS has previously been shown to be involved in recruiting the ubiquitin E3 ligase c-Cbl to the insulin receptor, the platelet-derived growth factor b-receptor and the erythropoietin receptor, leading to increased degradation of the receptors and inhibition of mitogenesis. Here we demonstrate, by use of immobilized synthetic phosphopeptides corresponding to various autophosphor
