Ozone fluxes in a Pinus ponderosa ecosystem are dominated by non-stomatal processes: Evidence from long-term continuous measurements

Ecosystems remove ozone from the troposphere through both stomatal and non-stomatal depositions. The portion of ozone taken up through stomata has an oxidative effect causing damage.We used amultiyear dataset to assess ozone deposition to a ponderosa pine plantation near Blodgett Forest, Georgetown, California. Environmental parameters, water and ozone concentrations and fluxes were measured co...

O-11: Zona Pellucida Birefringence and Meiotic Spindle Visualization of Human Oocytes Are Not Influenced by In Vitro Maturation Technology

Background: In vitro maturation (IVM) is a promising treatment option for certain infertile women. Nowadays, with the aid of the Polscope, it has become possible to evaluate zona pellucida (ZP) and spindle as parameters of oocyte quality. The goal was to investigate the relationship between the presence of the meiotic spindle and ZP birefringence with morphology of the in vivo and in vitro matu...
