VITAMIN A TERATOGENESIS IN A SENSITIVE GENETIC BACKGROUND

The Mechanism of Vitamin a Induced Teratogenesis.

IT IS generally recognized that some congenital malformations may be caused by an abnormal environment surrounding the mother in pregnancy. Many experiments have been reported concerning the teratogenesis due to various hypovitaminoses, but there are relatively few reports on teratogenesis resulting from the administration of a large quantity of vitamin.

Simple Sequence Repeats Amplification: a Tool to Survey the Genetic Background of Olive Oils

A reliable DNA extraction method for use on extra virgin olive oil based on a commercial kit was defined, and the possibility of using this DNA for fingerprinting the original cultivar was demonstrated. The genetic traceability of single-cultivar virgin olive oil from two cultivars (Carolea and Frantoio) was achieved by identifying the varieties from which they were produced. This involved the ...
