The abnormal pregnancies complete and partial hydatidiform mole are genetically unusual, being associated with two copies of the paternal genome. Typical moles (CHMs) diploid androgenetic, while (PHMs) diandric triploids. While diagnosis can usually be made on basis morphology, ancillary techniques that exploit their unusual genetic origin used to facilitate diagnosis. Genotyping p57 immunostai...

OBJECTIVES Distinction of hydatidiform moles from non-molar specimens and subclassification of hydatidiform moles as complete and partial are important for clinical practice, but diagnosis based solely on histomorphology suffers from poor interobserver reproducibility. Nowadays, pathologists rely on molecular techniques, however these methods are technically difficult, relatively expensive, and...

Zonula occludens-1 (ZO-1) and occludin are key molecules in cell-cell contacts. They are tight junction constituents and therefore play a pivotal role in tissue differentiation and organogenesis. In the present report we have investigated the expression of ZO-1 and occludin in normal human placentae and in hydatidiform moles using immunohistochemical and Western blot analyses. In normal placent...

Hydatidiform mole represents an abnormal form of conception that occurs in about one in 500-1000 pregnancies. It is a subtype of gestational trophoblastic disease. Hydatidiform moles should be regarded as premalignant lesions because 15-20% of complete hydatidiform moles (CHMs) and 1% of partial hydatidiform moles (PHMs) undergo malignant transformation into invasive moles, choriocarcinomas, or...

Mesophyll cells from leaves of cowpea (Vigna unquiculata [L.] Walp.) plants grown under saline conditions were isolated and used for the determination of photosynthetic CO(2) fixation. Maximal CO(2) fixation rate was obtained when the osmotic potential of both cell isolation and CO(2) fixation assay media were close to leaf osmotic potential, yielding a zero turgor pressure. Hypotonic and hyper...

I . Rates of disappearance of glucose from ligated loops of small intestine in lambs, adult sheep and young rats were studied. The concentration of glucose in the lumen decreased exponentially with time, suggesting that within a range of concentrations of 166-277 m-moles/l glucose was absorbed mainly by passive diffusion. 2. The rate of absorption of glucose from a 166 mM-solution based on eith...
