Ephrem and Transubstantiation

Q. Did Ephrem advocate the Roman dogma of transubstantiation?

Ephrem, the Syrian (c. 306-373 A.D.):

And when the brethren approached to take the holy bread, the body was extended to them; and when they invoked God, saying: Amen, bread was in their hands. …And when I said, I believe, O Lord, lo, while I said Amen, the body which was seen in my hand was bread, and I praised God and took the holy bread. (Serm. 2, de oblat.) Here see also (J. P. Minge, Encyclopédie Théologique, [1855], Tome Douziéme, S. Ephrem, de sacr. oblatione, t. III, Col. 147). Here Trans (J. H. Treat, The Catholic Faith; Or, Doctrines of the Church of Rome Contrary to Scripture and the Teaching of the Primitive Church, [1888], p. 175). Here 

Fire even has not one nature, but a double one, for it consists of wood and flame. In the same manner the bread consists not of one paneous nature, but also of a divine one. For the body, (namely of Christ) which is of one nature with the divine, rejoices not in one nature, but in a double nature. (Serm. de sanct. et vivific. Christ. Sacram.) Here see also (J. P. Minge, Encyclopédie Théologique, [1855], Tome Treiziéme, S. Ephrem, de sacrament., serm. 1, t. III, Col. 1121). Here Trans. (J. H. Treat, The Catholic Faith; Or, Doctrines of the Church of Rome Contrary to Scripture and the Teaching of the Primitive Church, [1888], p. 175). Here
