Predicting the Effects of Ozone on Long-Term Growth of Aspen Trees Using Response Functions Developed From Seedlings Grown in Field Chambers.

Tropospheric ozone (O) is among the most pervasive and harmful air pollutants known to affect ecosystems. In the United States, the Environmental Protection Agency and other agencies are tasked with protecting plants and ecosystems from harmful O exposures. Controlled exposure experiments conducted in field open-top chambers (OTCs) with small tree seedlings have been used to estimate empirical models of tree growth in response to O exposure for more than 16 species.

Women with Complex Vascular Anomalies: Impact on Contraception, Pregnancy and Reproductive Health.

Background: Literature is scarce regarding contraceptive and reproductive health in women with complex vascular anomalies (VA).

Objectives: To assess obstetrical, gynecological and reproductive health in this population.

Methods: Female adult patients of childbearing age from the VA clinic of a single tertiary care centre in Canada have been recruited by retrospective chart review, and administered phone interviews.

Domain-specific representation of social inference by neurons in the human amygdala and hippocampus.

Inferring the intentions and emotions of others from behavior is crucial for social cognition. While neuroimaging studies have identified brain regions involved in social inference, it remains unknown whether performing social inference is an abstract computation that generalizes across different stimulus categories or is specific to certain stimulus domain. We recorded single-neuron activity from the medial temporal lobe (MTL) and the medial frontal cortex (MFC) in neurosurgical patients performing different types of inferences from images of faces, hands, and natural scenes.
