Single drop microextraction using silver nanoparticles as electrostatic probes for peptide analysis in atmospheric pressure matrix-assisted laser desorption/ionization mass spectrometry and comparison with gold electrostatic probes and silver hydrophobic probes.

29 Sep 2008 Single drop microextraction using tetraalkylammonium bromide coated silver nanoparticles (SDME-AgNPs) prepared in toluene has been successfully applied as electrostatic affinity probes to preconcentrate peptide mixtures in biological samples prior ... Read more...

The effect of short-term hypobaric hypoxic exposure on intraocular pressure.

29 Sep 2008 PURPOSE: To evaluate the effect of short-term hypobaric hypoxic conditions (STHC) on intraocular pressure (IOP) in healthy subjects. METHODS: The study group was comprised of 30 healthy participants (60 eyes) with a mean age of 24.8 years. IOP was ... Read more...

Anomalous high-pressure behavior of amorphous selenium from synchrotron x-ray diffraction and microtomography.

Sep 2008 The high-pressure behavior of amorphous selenium has been investigated with time-resolved diamond anvil cell synchrotron x-ray diffraction and computed microtomography techniques. A two-step dynamic crystallization process is observed in which the ... Read more...
