Insect Biochemistry and Molecular Biology, 2013 Chorion proteins of Lepidoptera have a tripartite structure, which consists of a central domain and two, more variable, flanking arms. The central domain is highly conserved and it is used for the classification of chorion proteins into two major classes,

Clinical Genetics, 1986
This study is based on the processing of 115 samples of pure chorion. The different types of colony morphology, together with cytogenetic analysis, indicate the predisposition of chorion cells to artefacts of culture. Chorion survives longer than other foetal tissues and can be cultured when those are dead or contaminated (e.g.

Clinical Obstetrics and Gynecology, 1988
To the Editor.— The study by the National Institute of Child Health and Human Development on chorionic villus sampling omits one significant consideration. 1 Diagnostic information that indicates a genetic disorder places the affected fetus at high risk of an induced abortion. What is safe for the mother may portend ill for the unborn.

Establishment of Human Trophoblast Progenitor Cell Lines from the Chorion
Stem Cells, 2011 Placental trophoblasts are key determinants of in utero development. Mouse trophoblast (TB) stem cells, which were first derived over a decade ago, are a powerful cell culture model for studying their self-renewal or differentiation.

Chorionic Gonadotropin Tests for Diagnosis of Pregnancy and Chorionic Tumors
Postgraduate Medicine, 1969Various chorionic gonadotropin tests (HCG) for the diagnosis of pregnancy and chorionic tumors are reviewed. The tests divide into biological and immunological groups. Immunological methods are generally more sensitive than biological methods. A brief description of the widely used hemagglutination inhibition and latex particle agglutination methods

Immunocytochemistry of human chorionic gonadotropin in human chorionic villi
American Journal of Obstetrics and Gynecology, 1987The immunocytochemical localization of human chorionic gonadotropin was investigated in chorionic villi from the seventh to twelfth week of gestation. By the light microscopic peroxidase-antiperoxidase technique, positive reactions of human chorionic gonadotropin were found exclusively in the syncytiotrophoblast.

The sonographic diagnosis of chorionicity
Prenatal Diagnosis, 2005AbstractThe differentiation between mono‐ and dichorionic placentation in twin pregnancies is of clinical importance because of the significant difference in perinatal morbidity and mortality between the two, and the increased surveillance indicated in monochorionic gestations.

Interference in the Chick Chorion
Journal of General Microbiology, 1953SUMMARY: Experiments were carried out in an attempt to demonstrate in the chorionic cells of the chick chorio-allantoic membrane some of the interference phenomena with influenza viruses which are readily demonstrable in the allantoic cells. When a mixture of PR 8 and Lee viruses was inoculated on the chorion, no interference occurred; on the contrary,

X-ray diffraction studies of a silkmoth chorion
International Journal of Biological Macromolecules, 1983 High- and low-angle diffraction studies have been performed on mature chorion (eggshell) of the silkmoth, Antheraea polyphemus. The results confirm the prevalence of β-sheet structure, previously suggested by predictions based on known primary structure ...
