The present paper focuses on bridging the gap between inside and outside classroom learning experiences. We present Moles and Mini Moles, a learning software tools system specifically designed to serve this purpose. Secondary school students use these tools for hypothesizing, gathering, and transferring information learned within the classroom and testing their knowledge and recording their exp...

There are two main mechanisms of origin for complete hydatidiform mole: (a) fertilization of an empty egg by a haploid sperm followed by duplication (monospermic mole); and (b) fertilization of such an egg by two haploid spermatozoa (dispermie mole). The former is inevitably homozygous (homozygous mole), whereas the latter may be heterozygous for a given genetic marker (heterozygous mole). A re...

Histopathological assessment and flow cytometric analyses were carried out on 32 placentas (representative of each trimester) and 88 molar pregnancies. Three first trimester placentas were triploid, and the remaining 29 placentas were diploid. Of the 88 cases originally diagnosed as molar pregnancies, 26 were triploid (two complete moles, 20 partial moles, and four hydropic abortions); 59 were ...

Women with mutation in both alleles of the NLRP7 or C6orf221/KHDC3L genes are predisposed to diploid biparental moles, but it has also been suggested that mutation in these genes can predispose to diploid androgenetic or triploid moles and to other kinds of reproductive wastage. We have investigated the association between molar pregnancy and recurrent miscarriages regarding changes in the NLRP...

tubal pregnancies are common but presence of hydatidiform mole in tube is a rare entity. a woman of 53years presented with acute abdomen, preoperative pregnancy test was positive and ultrasonography suspected the case as hydatidiform mole in right tube. the patient was treated with total abdominal hysterectomy with bilateral salpingo-oophorectomy as her family was completed. subsequent histopat...

Work is described on the changes in cell ions during growth of cultures of a species of Halobacterium isolated from the Dead Sea. Cell K concentration fell from 5.5 to 3.8 moles per kg cell water during the logarithmic phase of growth and maintained the latter value during the stationary phase (initial medium concentration, 7 re_M). Cell Na and CI followed a complex series of roughly parallel c...
