Ambulatory management of primary spontaneous pneumothorax: an open-label, randomised controlled trial.

Background: Primary spontaneous pneumothorax occurs in otherwise healthy young patients. Optimal management is not defined and often results in prolonged hospitalisation. Data on efficacy of ambulatory options are poor.

Uptake of atrazine and cadmium from soil by maize (Zea mays L.) in association with the arbuscular mycorrhizal fungus Glomus etunicatum.

A greenhouse pot experiment was carried out to investigate the effect of the arbuscular mycorrhizal fungus Glomus etunicatum on the uptake of atrazine (ATR) and cadmium (Cd) from soil by maize (Zea mays L.). Mycorrhizal colonization led to an increase in the accumulation of Cd and ATR in maize roots but a decrease in the shoots.
