Are b-type and N-terminal pro-B-type natriuretic peptides equally useful in assessing patent ductus arteriosus in very preterm infants?
BNP and NTproBNP are similarly useful for assessing PDA size in preterm infants.
A small proportion of photosynthetically fixed CO(2) was derived from the soil, with minimal associated transpirational H(2)O loss into the space between the leaf and soil. The soil-derived CO(2), taken up through the lower surface was probably assimilated by the palisade tissue in the upper surface of the leaf which was exposed to sunlight and where most of the leaf N was located. The occurrence of lysigenous air channels in the leaves may provide longitudinal strength without impaired transfer of CO(2) taken up through the lower surface to the upper surface.
