A first step to improving maternal mortality in a low-literacy setting; the successful use of singing to improve knowledge regarding antenatal care.

Background: Preventable maternal mortality is related to delays in recognizing the problem, transport to a facility, and receiving appropriate care on arrival. Reducing maternal mortality in low-literacy settings is particularly challenging. In the rural villages of Nepal, the maternal mortality rate is among the highest in the world; the reasons include illiteracy and lack of knowledge of the needs of pregnant women.

Perigraft adventitia and intima remodeling after synthetic patch implantation in sheep carotid artery: role of apoptosis and proliferation.

Background: The mechanisms of neointima formation after synthetic vascular grafting are not clear. The aim of this study was to investigate the intima and perigraft adventitia remodeling process in terms of cell apoptosis versus proliferation after synthetic patch implantation.

Methods: Female Merino sheep were randomized equally into two groups and underwent implantion with a patch of gelatin sealed Dacron graft into the left common carotid artery.
