out of IO patients with absence of the sixth aortic arch, by means of selective catheterization of the major aortopulmonary collateral arteries. Three patients were infants. Total pulmonary resistance was severely raised, and exceeded 9 .5 units m2 in all patients while breathing room air, but fell significantly upon breathing IOO per cent oxygen. The younger patients had a significantly lower ...

The extraction and processing of starch from agricultural commodities is one of the most important agro-industries world wide. By the early 1990s, global production of starch probably exceeded 38 million metric tons (mmt) per year for a market value of at least $11 billion. In Asia, starch production was about 16 mmt and demand for starch by food and non-food industries was growing by 5-10 perc...

The kidney graft survival rate at the Belfast City Hospital has consistently exceeded 80% at two and three years since the transplant programme began in 1968. This graft survival rate compares very favourably with that of other centres and should mean a difference in graft survival for paired kidneys when one kidney is used for a Northern Ireland recipient and the other for a recipient 'outside...
