Ooids are a major constituent of the Pleistocene carbonates along the northwestern coastal ridges of Egypt. For a detailed diagenetic study of the rocks, the Mersa Matruh area was selected. Petrographic examination shows ...
Regenerative abnormalities in hind limbs of bufo regularis induced by repeated amputations: I. Early larval stages
(
Qatar University
, 1993 , Article)
The regenerative response of the hind limbs of early larval stages: 52, 53, 54 and 55 of Bufo regularis was studied following repeated amputations at the ankle level. The pattern of morphogenesis as well as skeletal ...
