Dispermic Origin And Clinical Outcome Of Three Complete Hydatidiform Moles With 46,Xy Karyotype, U. Surti, A. E. Szulman, S. O'Brien
Dispermic Origin And Clinical Outcome Of Three Complete Hydatidiform Moles With 46,Xy Karyotype, U. Surti, A. E. Szulman, S. O'Brien
Biology Faculty Articles
Three new cases of complete, classic hydatidiform mole with a 46,XY karyotype are described. They originated by dispermy as demonstrated by chromosome and enzyme analyses. Levels of human chorionic gonadotropin decreased to normal spontaneously within a short time, indicating a benign course in these three cases. Of a total of 18 cases reported to date, postoperative clinical information was available for 10 patients. Two of these 10 patients had a malignant course with lung metastases. It is of theoretical and clinical importance to establish the magnitude of the risk of malignancy for hydatidiform mole with a 46,XY karyotype. © 1982.

To compare in quantitative terms both ecological characteristics of the stony coral fauna at various reef sites in Bermuda and available assessment methodologies, we present a study of four separate methods at each of three reef sites. Three plotless (Intersected-length, Quarter point, Point) and one quadrat (Belt-quadrat) methods were employed. Each technique gave similar results but had inherent advantages and disadvantages which involve trade-offs in quantity and type of information generated and time required for use.
Pooling of method results revealed that total coral coverage was highest at North Rock (26%), intermediate at Three Hill Shoals (17%), and lowest at …

Evidence For The Horizontal Acquisition Of Murine Akr Virogenes By Recent Horizontal Infection Of The Germ Line, Stephen J. O'Brien, Janet L. Moore, Malcolm A. Martin, James E. Womack

Several recent reports have established the biological and molecular genetic similarity between the endogenous AKV virus of strain AKR, and an N-ecotropic endogenous virus found in the genome of feral Japanese mice, Mus musculus molossinus. The similarities are so striking as to suggest a common origin of these viruses, which are present in some, but not all, inbred mouse strains. The virogenes of AKR mice may have been acquired by either: (a) common descent of AKR (and other AKV+ strains) from a common ancestor of AKR and molossinus animals, or (b) horizontal germ line infection of the AKR …
