Developmental defects in the lungs.
An increasing number of congenital abnormalities of the lung is becoming recognized during life. Nineteen such cases of particular interest are described. They have been selected from a group of 37 patients with congenital lung defects, of which 35 have been operated on by one surgeon since 1939. In five cases the intrathoracic abnormalities are threefold, in nine a double abnormality is presen...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Developmental changes in Endothelin-1 and Endothelin type A receptor expression in the lungs of chickens (Broiler versus layer)
Background: Broilers lung mechanisms that regulate endothelin (ET) in the lung are complex and poorly understood. Objectives: Methods: In this experiment lung ET-1 mRNA levels and lung mRNA expression for the ET(A) receptors were determined in lung tissue weekly (term = 42 days, intervals = 7 days). Serum endothelin concentration was also measured at these ages. Results: The study showed that e...
متن کاملLethal Developmental Defects: An Overview
About 3% of all conceptions are associated with major congenital malformations, many of them are lethal developmental defect and genetic in origin or teratogenic (adverse effects of the environment during gametogenesis or early embryogenesis). Genetics with or without adverse environment has role in virtually every developmental defect/malformation disorders in causation, predisposition, suscep...
متن کاملDevelopmental defects in Rb-deficient retinae
We recently found that the Rb protein is important for the regulation of retinal progenitor cell proliferation and rod photoreceptor development in the mouse retina. These two functions are separate for Rb and in this study we further characterize the role of Rb in retinal development. At postnatal day 12 in the retinae of Chx10-Cre;RbLox/- mice, immature cells are found in the outer nuclear la...
