[A]: yes


[Q]: Question: Does expression microarray identify the unliganded glucocorticoid receptor as a regulator of gene expression in mammary epithelial cells?
Answer: This work presents the first identification of targets of unliganded GR. We propose that the balance between targets of liganded and unliganded GR signaling is responsible for controlling differentiation and apoptosis, respectively, and suggest that gene regulation by unliganded GR may represent a mechanism for reducing the risk of breast tumourigenesis by the elimination of abnormal cells.
[A]: yes


[Q]: Question: Does administration of 100 % oxygen before removal of the laryngeal mask airway affect postanesthetic arterial partial pressure of oxygen?
Answer: The endotracheal tube and laryngeal mask airway are substantially different artificial airways used to ventilate the lungs of anesthetized patients. Breathing 100% oxygen before removing the endotracheal tube results in lung function defects. This study shows that oxygen breathing before removing the laryngeal mask airway has no effect on pulmonary function.
[A]:
no
