A new method for the detection of Raman scattering from atmospheric pollutants

The Fabry-Perot interferometer can be used as a periodic filter for the sorting of spectra using the rotational Raman effect. Thus it is possible to detect low concentrations of impurities in the presence of the major atmospheric constituents. The parameters of importance in making these measurements and the expected results from this technique are discussed from theoretical computations.     

Prenatal stress and subsequent exposure to chronic mild stress influence dendritic spine density and morphology in the rat medial prefrontal cortex

Background  

Both prenatal stress (PS) and postnatal chronic mild stress (CMS) are associated with behavioral and mood disturbances in humans and rodents. The aim of this study was to reveal putative PS- and/or CMS-related changes in basal spine morphology and density of pyramidal neurons in the rat medial prefrontal cortex (mPFC).
