Season of birth predicts mortality in rural Gambia

Article Abstract:

There is evidence to suggest that babies born during the annual season of food shortages in rural Gambia are likely to die sooner than those born at other times of the year. This is because malnutrition in pregnant women seems to have a permanent impact on the development of the immune system of the foetus. Other stresses, including the need to undertake a great deal of agricultural work and high levels of malaria, can also produce retardation of foetal growth and severely affect the growth of small children.

The prostaglandin receptor EP4 triggers remodelling of the cardiovascular system at birth

Article Abstract:

Research has established that mice with ductus arteriosus (DA) closure experience very similar morphological changes as human beings suffering from the same condition. Evidence suggests that prostaglandin synthesis plays a key role in DA maintenance. The prostaglandin E2 EP4 -/- receptor is thought to sense deficient prostaglandin levels in the blood stream.

A single birth of all plastids?

Article Abstract:

Early photosynthetic organelles and cellular mitochondria have long been presumed to have arisen from bacteria parasitising single-celled organisms. New evidence suggests a common origin of all primary plastids, particularly green and red algal plastids and, with weaker evidence, glaucophyte plastids.
