Understanding the interface between dental materials and tooth is critical in the prevention of secondary caries. Assessing this interface with high-resolution clarity has traditionally been challenging. This work highlights electron tomography, carried out in the transmission electron microscope, as a novel technique to obtain both three-dimensional and nanometer scaled information on dental m...
Voltage-gated calcium channels play a key role in chemical synaptic transmission by providing the calcium trigger for regulated neurotransmitter release. Genes encoding the primary structural subunit, alpha1, as well as accessory subunits of presynaptic calcium channels have now been identified in a variety of organisms. The cacophony (cac) gene in Drosophila, also known as nightblind A, encode...
The elasticity of monocarboaluminate hydrates, 3CaO·Al2O3·CaCO3·xH2O (x = 11 or 8), has been investigated by first-principles calculations. Previous experimental study revealed that the fully hydrated monocarboaluminate (x = 11) exhibits exceptionally low compressibility compared to other reported calcium aluminate hydrates. This stiff hydration product can contribute to the strength of concret...
Our previous genetic analysis of synaptic mechanisms in Drosophila identified a temperature-sensitive paralytic mutant of the voltage-gated calcium channel alpha1 subunit gene, cacophony (cac). Electrophysiological studies in this mutant, designated cac(TS2), indicated cac encodes a primary calcium channel alpha1 subunit functioning in neurotransmitter release. To further examine the functions ...
Stabilization/Solidification technologies reduce the mobility of hazardous and radioactive contaminants in the environment through both physical and chemical processes. Four stabilization/solidification (S/S) processes were used to solidify three sample matrices contaminated with arsenic, chromium (VI), lead, cesium and strontium. These sample matrices were Idaho National Engineering and Enviro...
BACKGROUND Recent randomized data suggest that calcium supplements may be associated with increased risk of cardiovascular disease (CVD) events. Using a longitudinal cohort study, we assessed the association between calcium intake, from both foods and supplements, and atherosclerosis, as measured by coronary artery calcification (CAC). METHODS AND RESULTS We studied 5448 adults free of clinic...
