UNLABELLED Coronary artery anomalies are rare in population and most of them are found incidentally during coronary angiography. Percutaneous treatment of critical lesions on anomalous arteries may lead to difficulties due to their abnormal origin or course. Herein, we report a 65-year-old male patient presented with recent onset chest pain. Electrocardiogram and transthoracic echocardiography ...

Neurons in cortical area V4 respond selectively to complex visual patterns such as curved contours and non-Cartesian gratings. Most previous experiments in V4 have measured responses to small, idiosyncratic stimulus sets and no single functional model yet accounts for all of the disparate results. We propose that one model, the spectral receptive field (SRF), can explain many observations of se...

PURPOSE To evaluate the results of balloon angioplasty of 17 stenoses resulting from intracranial atherosclerosis and vasculitis. METHODS Seventeen skull-base and intracranial lesions were dilated with a microballoon angioplasty catheter. RESULTS Initially, 16 of the 17 stenoses showed improvement at angiography. Moderate residual stenosis was found in 2 of 12 atherosclerotic lesions, both ...

mandibular premolars have earned a reputation for having aberrant anatomy. the occurrence of three canals with three separate foramina in mandibular premolars is very rare. if predictable treatment of a three rooted mandibular premolar is planned, precise knowledge of clinical and radiographic anatomy is absolutely necessary. these teeth may also require special shaping and obturating technique...

It has been stated that the electrocardiogram in pulmonary valve stenosis gives an accurate estimate of right ventricular systolic pressure. Nadas (1957) writes "we have not found any patient with a right ventricular systolic pressure of more than 100 mm. of Hg who has not demonstrated at least one of the following three important electrocardiographic criteria: (1) RVY of more than 20 mms., (2)...

Atlas bridges, the bony outgrowths over the third segment of the vertebral artery are associated with compression of the artery and nerves. There are limited studies comparing morphometry of the complete atlas bridges and that of the ipsilateral transverse foramen. Bilateral and gender differences in the morphometry of the complete bridges remain relatively unexplored. One hundred and two atlas...
