Temperature and fluid pressure conditions control rock deformation and mineralization on geological faults, and hence the distribution of earthquakes. Typical intraplate continental crust has hydrostatic fluid pressure and a near-surface thermal gradient of 31 ± 15 degrees Celsius per...

Helicobacter pylori NikR (HpNikR) is a nickel dependent transcription factor that directly regulates a number of genes in this important gastric pathogen. One key gene that is regulated by HpNikR is ureA, which encodes for the urease enzyme. In...

OBJECTIVE: To evaluate, firstly, all published data on baseline and annual progression rates of radiographic damage from all longitudinal observational cohorts, and secondly, the association of standard clinical and laboratory parameters with long-term radiographic joint damage.METHODS: A comprehensive search...

Prediction of enhanced solvent-induced enantioselectivity for a ring opening with a bifurcating reaction path.

Classical molecular dynamics simulations are reported for the deazetisation and ring opening of meso-2,3-difluoro-2,3-dimethyldiazocyclopropane in three solvents: CHCl3, CHFClBr and CH3CH(OH)CF3 (TFIPA). The achiral reactant leads to enantiomeric allene products, and the question addressed in the study is whether...

Targeting the Sonic Hedgehog Signaling Pathway: Review of Smoothened and GLI Inhibitors.

The sonic hedgehog (Shh) signaling pathway is a major regulator of cell differentiation, cell proliferation, and tissue polarity. Aberrant activation of the Shh pathway has been shown in a variety of human cancers, including, basal cell carcinoma, malignant gliomas,...

Glycolysis and the significance of lactate in traumatic brain injury.

Front Neurosci. 2015 Apr 08;9:112. doi: 10.3389/fnins.2015.00112. eCollection 2015.

In traumatic brain injury (TBI) patients, elevation of the brain extracellular lactate concentration and the lactate/pyruvate ratio are well-recognized, and are associated statistically with unfavorable clinical outcome. Brain extracellular lactate was conventionally regarded as a waste product of glucose,...

Understanding the puzzling chemistry of bicyclo[2.1.0]pentane.

Org Biomol Chem. 2004 Jan 07;2(1):103-9. doi: 10.1039/b310676d. Epub 2003 Nov 13.

Three thermal reactions of bicyclo[2.1.0]pentane have been studied by CASPT2-g3 and CASSCF electronic structure calculations. They are isomerization to cyclopentene, isomerization to 1,4-pentadiene, and cycloaddition to fumaronitrile. All three of these reactions exhibit unusual features that have prompted mechanistic...

Calculations at the MP2/aug-cc-pVDZ//MPWB1K/aug-cc-pVDZ level are reported for the reduction of CO2 by amines--primarily triethylamine. A polarizable continuum model is used to represent acetonitrile solvent for the reaction. Starting from a photochemically generated radical ion pair state, the mechanism...
