Live imaging reveals that the Drosophila oocyte nucleus is pushed by growing microtubules to break the radial symmetry of the oocyte and establish dorsoventral polarity.

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...

Methods Fifty-nine patients with rTOF (median age 28 years, range 15-69) underwent cardiovascular magnetic resonance (CMR) from 2008-2009 and completed the Short Form 36 (a validated quality of life assessment). A midventricular short-axis slice was analyzed for left ventricular global circumferential strain (LVGCS) with feature tracking software (TomTec, Unterschleissheim, Germany). A four-cha...

No data are available on determining right atrial and right ventricular size by two-dimensional echocardiography. We performed two-dimensional echocardiograms on eight human right-heart casts obtained at autopsy and on 50 patients who underwent complete left- and right-heart catheterization. Measurement of individual dimensions of the long and short axes of the right atrium and ventricle from r...

BACKGROUND Analysis of right ventricular adaptation to tricuspid regurgitation was studied in 10 heart transplant recipients following inadvertent endomyocardial biopsy disruption of the tricuspid apparatus. METHODS AND RESULTS Echocardiography demonstrated progressive diastolic right ventricular cavity enlargement (19.5+/-5.0 to 30.3+/-5.4 cm(2), P<0.0002), with disproportionate elongation a...
