same variables in corresponding patients. The echo-measured left ventricular enddiastolic chamber dimension (Dd) correlated closely with the angiographic minor axis in the AP plane (correlation coefficient 0.87 and SE -+-0.45 cm) and with the minor axis from the lateral film (r 0.91, SE +0.39 cm). Similar correlations were found between measurements by these methods of wall thickness (r = 0.89,...

  Background: Proper rotation of components in total knee arthroplasty (TKA) will largely affect the postoperative outcome. Ethnical variation may affect rotational profile. We aimed to evaluate distal femur rotation in Iranian population using transepicondylar axes.   Methods : From a total of 450 knee CT scans and via consecutive sampling, 150 qualified subjects with normal lower extremities ...

This paper reports the results of lattice Boltzmann simulations of the rotation behaviour of neutrally buoyant spheroidal particles in a three-dimensional Couette flow. We find several distinctive states depending on the Reynolds number range and particle shape. As the Reynolds number increases, rotation may change from one state to another. For a prolate spheroid, two rotation transitions are ...

BACKGROUND Adenoid cystic carcinoma (ACC) and adenoid basal carcinoma (ABC) are rare in the uterine cervix. ACC is more aggressive than ABC, thus accurate differential diagnosis is important. In this study, we identified cytologic features useful in distinguishing these two tumors for diagnosis. METHODS Three cases of ACC and five cases of ABC were selected for this study. Cervicovaginal smea...

 ABSTRACT Background: High resolution CT scan has made early diagnosis of intraventricular hemorrhage (IVH) easier. Posttraumatic intraventricular hemorrhage has been reported to a greater extent because of the CT scan. Methods: 904 patients were admitted in the NSICU from March 2001 to March 2002 with severe closed head injury, of those only 31 patients with intraventricular hemorrhage (GCS le...

In this paper we discuss the reason why the parameters of the Sérsic model best-fitting the major axis light profile of elliptical galaxies can differ significantly from those derived for the minor axis profile. We show that this discrepancy is a natural consequence of the fact that the isophote eccentricity varies with the radius of the isophote and present a mathematical transformation that a...

We compared dimensions of the left ventricular minor axis (S) measured at enddiastole (SD) and end-systole (Ss) by echocardiography with dimensions and left ventricular volumes measured by biplane angiocardiography in 27 patients with diverse cardiac abnormalities. There were high correlations between echographic and angiographic ventricular minor-axis dimensions (r 0.85 for SD and 0.87 for SS)...

Acute right ventricular pressure overload shifts the interventricular septum leftward and decreases systolic shortening of the left ventricular (LV) septal-lateral diameter. These changes should alter regional shortening in the LV minor axis. To test this hypothesis, LV minor axis circumferential segment lengths of the septum and anterior, lateral, and posterior walls were measured during pulmo...
