Duplication of the vas deferens is a very rare congenital anomaly in which two vasa deferentia coexist within the spermatic cord. Duplication of the vas deferens can be found during herniorrhaphy, vasectomy, and varicocelectomy performed on the spermatic cord or around the spermatic cord. However, it is estimated that the incidence of duplication of the vas deferens is under-reported and under-...

Voluntary Agreements for the Environment (VAs) are collaborative arrangements between industry and regulators in which firms voluntarily commit to actions that improve their environmental performance. VAs differ from inter-firm alliances in that they involve partners of a dissimilar nature. The primary objective of regulators is the procurement of social benefits while that of firms is the purs...

The Drosophila gene vasa (vas) encodes an RNA-binding protein required for embryonic patterning and germ cell specification. In vas mutants, translation of several germline mRNAs is reduced. Here we show that VAS interacts directly with the Drosophila homolog of yeast translation initiation factor 2, encoded by a novel gene, dIF2. Embryos produced by vas/+; dIF2/+ females have pattern defects a...
