Pathophysiological consequences of VEGF-induced vascular permeability.

abstract：:The study of the extent and basis of gene-enzyme variation has long been a principal concern of population genetics. Numerous surveys have indicated considerable amounts of genetic variation detectable in natural populations, with few exceptions. The variances of average heterozygosities (H) between species and among ...
