Cardioprotection from ischemia by a brief exposure to physiological levels of ethanol: role of epsilon protein kinase C.

abstract：:Genomic regions of nearly every species diverged into different haplotypes, mostly based on point mutations, small deletions, and insertions that do not affect the collinearity of genes within a species. However, the same genomic interval containing the z1C gene cluster of two inbred lines of Zea mays significantly lo...
