Abnormal uterine bleeding is any bleeding from the uterus other than normal monthly period. Having extremely heavy bleeding during period can also be considered abnormal uterine bleeding. Dysfunctional uterine bleeding (DUB) is heavy or irregular menstrual bleeding that is not caused by an underlying anatomical abnormality, such as a fibroid, lesion, or tumor. DUB is the most common type of abn...

Cineangiography of the left ventricle during exercise has been used in an attempt to define the area of ischaemic myocardium in patients suffering from angina pectoris in whom coronary artery surgery was contemplated. A correlation was established between the site of coronary artery obstruction and the area of abnormal myocardial contraction. This method of localization of regional left ventric...

We previously developed a cross-sectional echocardiographic technique for quantitatively mapping the endocardial surface of the left ventricle and on which regions of abnormal wall motion can be superimposed in their correct spatial distribution. This endocardial mapping technique (EMT) provides a measure of the left ventricular endocardial surface area (ESA in cm2), the area of abnormal wall m...

In this paper, a novel design of near-field dipole antenna sensor array for breast tumor detection is presented. The proposed consists four electrically small antennas fed by single port. Due to the proven fact that tumors have higher dielectric properties than surrounding normal tissues, utilized detecting evaluating variations sensor’s response two cases, and abnormal, tissues. A simulation s...

The results of previous work from this laboratory have shown a poor correlation between percent stenosis (determined visually with calipers) and the coronary reactive hyperemic response (an index of maximal coronary vasodilator capacity) determined during cardiac surgery. This study was performed to determine whether other parameters of lesion severity could predict the reactive hyperemic respo...

Body surface isochrone mapping was performed in 36 normal subjects and in 85 patients with previous myocardial infarction. Eighty-seven unipolar electrocardiograms distributed over the anterior chest and the back were recorded simultaneously. For each lead, activation time was measured as the time from the onset of QRS to the peak of the R wave. The lead points where R waves were not observed w...

OBJECTIVE To identify and evaluate the lateral border zone by comparing the size and distribution of the abnormal signal area demonstrated by MR imaging with the infarct area revealed by pathological examination in a reperfused myocardial infarction cat model. MATERIALS AND METHODS In eight cats, the left anterior descending coronary artery was occluded for 90 minutes, and this was followed b...
