large intercoronary communications in the absence of obstructive coronary artery disease constitute a very rare coronary artery anomaly in which there is a readily visible connection between the 2 coronary arteries with a unidirectional or bidirectional blood flow; consequently, this anomaly may be misinterpreted as a functioning collateral vessel, indicative of an unrecognized proximal coronar...

for the first time, a spectrum of morphological abnormalities have been produced in developingmouse embryos (n=50), by injecting (ip) 75 and 100 mg/kg of maternal body weight of a new quinazolinonederivative, 4(3h)quinazolinone-2-propyl-2-phenylethyl(qppe), on days 9, 10 and 11 of gestation.measurements of the length of the crown-rump (cr), weight of body of the embryos and placenta on day 17sh...

ultrasonography is the only practical method for obtaining images of the posterior segment of the eye when the light-conducting media are opaque. in this study, 182 dogs with ocular abnormalities presented to the department of veterinary surgery and radiology from december 2008-august 2010 were included. all the animals were subjected to detailed ophthalmic examination and b-scan ultrasonograph...

Microtubules have a central role in cell division and cell polarity in eukaryotic cells. The fission yeast is a useful organism for studying microtubule regulation owing to the highly organised nature of its microtubular arrays. To better understand microtubule dynamics and organisation we carried out a screen that identified over 30 genes whose overexpression resulted in microtubule cytoskelet...

An objective method for measuring bovine sperm nuclear shape was developed. Digital images of bovine sperm stained with propidium iodide were collected and Fourier functions used to describe the perimeters of individual sperm nuclei. Harmonic amplitudes from Fourier functions were first shown to be independent of sperm orientation during digitization. Sperm from 12 different bulls were used, an...

litis study is based on embryotoxic effects of ethanol on embryos and discussing the morphologic and hhtahtgic changes and defects an mouse. tlie female animals were divided in three groups. hie first group untreated as a control group but the second and third group received 10% and 20% solutions of ethanol respectively. animals get use to certain level of ethanol solution and in the 10th day, ...

it has been recognized that patients with cyanotic congenital heart disease (cchd) show significant bleeding tendency which can be secondary to coagulopathies in these patients. some coagulation abnormalities are thrombocytopenia, factor deficiencies, fibrinolysis and disseminated intravascular coagulation  (dic). according to high prevalence of cchd and major operations in theses patients, the...
