the present work was designed to evaluate the in vitro lipid peroxidation inhibitory and antimicrobial activities of the methanol extract of phyllanthus niruri (mepn) (family:   euphorbiaceae) .   lipid peroxidation was measured by the optical density of the prepared solutions (10-320 µg/ml) and then the percent inhibition was calculated. ascorbate/feso 4 -induced peroxidation was inhibited by ...

We visualized respiratory neuron activity covering the entire ventral medulla using optical recordings in a newborn rat brainstem-spinal cord preparation stained with voltage-sensitive dye. We measured optical signals from several seconds before to several seconds after the inspiratory phase using the inspiratory motor nerve discharge as the trigger signal; we averaged the optical signals of 50...

In this paper, structural, magnetic, optical, and photocatalytic properties of core-shell structure Fe3O4@GO nanoparticles have been compared with Fe3O4 nanoparticles in the degradation of methyl blue and methyl orange. For this purpose, GO nanosheets were wrapped around the APTMS-Fe3O4 nanoparticles and then charact...

Tetragonal zirconia (t-ZrO2) nanoparticles were synthesized from thezirconium chloride using the co-precipitation technique and characterized by variousmeasurement techniques. FESEM analysis further revealed spherical shaped NPs andHR-TEM analysis determined the size of the particles in the range of 14.5 nm. The bandgap energy was estimated 4.0 eV. The UV (350 nm) emissi...
