Differential gene expression in aortae isolated from mice consuming normal water or that containing polystyrene beads
<p>Microplastics (MP) derived from the degradation of larger polymers or synthesized for commercial purposes are ubiquitous in the environment and have found their way into food supplies and water systems where human consumption is inevitable. We hypothesize that MP ingestion promotes CVD risk and atherosclerosis. To test this idea, we supplied ApoE-/- mice with normal chow and either normal water or that containing polystyrene (PS) beads (0.5 μm in diameter; dose of 1 μg/ml). After 20 weeks of exposure, we evaluated lesion formation and gene expression data in cardiovascular tissue. We observed that mice consuming the PS water had increased lesion size compared to those mice consuming normal water. but no changes in plasma lipids or cytokines. An RNAseq analysis of collected aortae identified 1622 differentially expressed genes between the groups, consisting of 414 that were up-regulated and 1208 that were down-regulated. </p>

Using Mie scattering to determine the wavelength dependant refractive index of polystyrene beads with changing temperature
<p>Polystyrene beads are used as test aerosol. A contact-less technique is reported for determining the size and refractive index of a solid aerosol particle as a function of wavelength and temperature (20-234°C). Polystyrene beads of 2μm diameter were optically trapped in air, in the central orifice of a ceramic heating element and Mie spectroscopy (0.480-0.650μm) was then used to determine the radius and refractive index (to precisions of 0.8nm and 0.0014) of 8 beads as a function of heating and cooling. Refractive index, n, as a function of wavelength, λ, in microns, and temperature, T, in centigrade, was found to be n = 1.5753 - (1.7336 × 10<sup>14</sup>) T + (9.733 × 10<sup>-3</sup>) λ<sup>-2</sup> in the temperature range 20 < T < 100 °C and n = 1.5877 - (2.9739 × 10<sup>-4</sup>) T + (9.733 × 10<sup>-3</sup>) λ<sup>-2</sup> in the temperature range 100< T <234 °C, significantly extending the temperature and wavelength range for refractive index of polystyrene. The work represents a step change in measuring the refractive index of materials in an absolute manner with high precision as a function of temperature and wavelength simultaneously. The work also demonstrates a new development in measurement of refractive index as a function of wavelength and temperature for measuring phase changes.</p>
