Reconstructing coral calcification fluid dissolved inorganic carbon chemistry from skeletal boron: An exploration of potential controls on coral aragonite B/Ca.

The boron geochemistry of coral skeleton reflects dissolved inorganic carbon (DIC) chemistry of the fluid where the skeleton calcification of sediment and may be a valuable tool for investigating the effects of climate change on coral calcification.

In this paper I calculate the predicted B / Ca of the originator of aragonite from sea water-based fluids as a function of pH, [DIC] and [Ca2 +]. I consider the species DIC co-originator of how different influences aragonite B / Ca and also estimate the impact of variations in the B (OH) 4 / co-accelerate the partition coefficient of aragonite DIC (KD), which may be related to changes in DIC and Ca2 + chemical fluid calcification.

Reefs order B / Ca against calcification fluid pH previously reported relationship can be reproduced by estimating B (OH) 4 and the co-precipitate speciation DIC as a function of pHCF and assuming constant KD is not affected by the state of calcification fluid saturation. Assuming that B (OH) 4 co-precipitation with CO32-, then the observed pattern can be reproduced by a fluid with about constant [DIC] is increasing pHCF CO32- concentration, as a function of speciation DIC.

Assuming that B (OH) 4 co-precipitation with any HCO3- or CO32- + HCO3- then the observed pattern can be reproduced if [DIC] CF and related pHCF which is positive if DIC is increasingly concentrated in the liquid at a higher calcification pHCF possible with CO2 diffusion into the site of calcification.

Collision-induced dissociation of double-charged ions: Coulomb explosion vs. a loss of neutral in [Ca (urea)] 2+ reactivity unimolecular gas phase through chemical dynamics simulations.

In this paper we report the different theoretical approaches for studying gas-phase unimolecular dissociation of double-charged cations Ca (urea), to rationalize experimental findings recently. Quantum mechanics plus mechanical (QM / MM) Direct chemical molecular dynamics simulations were used to investigate the collision induced dissociation (CID) and the rotational-vibrational energy transfer to Ar + Ca (urea) collision. For picosecond time-domain simulation, both neutral and reaction losses Coulomb explosion discovered and described differences in their mechanisms.

The loss of urea neutral after a collision with Ar happen through destroying mechanism, while the formation of single-charged cations following two statistics (or almost statistics) dynamics. energy transfer efficiency of vibration-rotation obtained for the trajectory that does not separate during the integration path is used in conjunction with a rate constant of dissociation pathways RRKM to estimate the complete assumption intramolecular vibration energy redistribution (IVR) and statistical dynamics.

Limit these statistics to predict, as expected, that in a long time the most stable species on the potential energy surface (PES) dominates. These results, coupled with a good experimental CID neutral loss and Coulomb explosion product was obtained, indicating that the gas phase ion dissociation This occurs by several mechanisms that lead to different products and that the reactivity of the complex PES is a complex dynamic.

Description: BACE2 Antibody: Accumulation of the amyloid-beta (Abeta) plaque in the cerebral cortex is a critical event in the pathogenesis of Alzheimer's disease. Abeta peptide is generated by proteolytic cleavage of the beta-amyloid protein precursor (APP) at beta- and gamma-sites by proteases. The long-sought beta-secretase was recently identified by several groups independently and designated beta-site APP cleaving enzyme (BACE) and aspartyl protease 2 (Asp2). A BACE homolog was recently cloned and designated BACE2, Asp1, DRAP (for Down region aspartic protease), and memapsin 1. BACE2 also cleaves APP at beta-site and at a different site within Abeta. BACE2 locates on chromosome 21q22.3, the so-called ‘Down critical region', suggesting that BACE2 and Abeta may also contribute to the pathogenesis of Down syndrome.
