Journal of Structural Biology, 2004 Chorion, the major component of silkmoth eggshell, consists of the A and B classes of low-molecular weight structural proteins. Chorion protects the oocyte and the developing embryo from environmental hazards and this is due to the extraordinary physical

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,

Crossing the chorion: Amniocentesis
The Journal of Pediatrics, 1964“The death of a human fetus with erythroblastosis fetalis may have been preventedby intrauterine blood transfused into the fetal peritoneum around the 30th week of pregnancy.” News item, The Medical Tribune, World Wide Report, Rochester, N. Y., March 27, 1964.

Endocrine Reviews, 1991
Cells from the chorionic girdle of the equine trophoblast invade the maternal endometrium at day 36 of gestation and become established as secretory elements known as the endometrial cups. These structures, which persist for 40-60 days, produce a gonadotropin which can be found in circulation until about day 130 of gestation. This glycoprotein has been

Current Opinion in Obstetrics and Gynecology, 1995
Chorionic villus sampling (CVS) has the great advantage over mid-trimester amniocentesis of producing early results. Moreover, rapid analytic techniques have significantly reduced the waiting time between sampling and diagnosis, whereas progress in recombinant DNA technology and human gene mapping has led to an increase in the range of conditions it ...

Chorion-carcinoma—Radiotherapy
Clinical Radiology, 1964Summary A series of twenty-five cases of chorion-carcinoma is discussed, of which four were discarded on further histological scrutiny, one died from other causes, eleven died from chorion-carcinoma and nine are alive and well at five years or more.
