Integrative analysis reveals pathways associated with sex reversal in Cynoglossus semilaevis.

abstract：:Background. Caesarean birth rates in North America continue to rise, in the absence of benefit for mothers and babies. One reason may be that hospitalized labouring women spend most of their labours in recumbent or semi-recumbent positions. Although hands-and-knees position has theoretical advantages, efforts to encou...

The single nucleotide polymorphism (SNP) of MTHFR gene (rs1801133, C667T) is correlated with decreased enzyme activity that eventually results in elevated plasma Hcy levels. Hyperhomocysteinem...
