We report upon a patient with multiple, progressive episodes of temporary monocular blindness associated with acute thrombosis and a critical internal carotid artery stenosis. Carotid angiography demonstrated an anatomically compelling situation cons

Management of patients with significant risks for thromboembolism in the perioperative period requires consideration of both risks of thromboembolism and risks of anticoagulant therapy. Patients who are receiving warfarin therapy because of recent ve

The isostatic compaction and hydrostatic extrusion of two atomized powders, namely Alcoa grade 1202 aluminium and Atomet 28 iron, are described and it is shown that the extrusion pressures for these powders may be 50-100 per cent greater than for an

The problem of the existence of solid solutions between pyrrhotite and pentlandite, chalcopyrite, galena, and sphalerite was investigated by heat treatment. Pentlandite was put into solid solution in pyrrhotite above 425 degrees C. Upon slow cooling

Torre’s model of a hollow sphere subjected to external pressure, developed to represent the compaction behaviour of a porous body, has been modified to cover strain-hardening of the material. Numerical results from this model show that as the strai

Although corticosteroids have been shown to stabilize lysosomal membranes and prevent release of hydrolytic enzymes, the mechanism of membrane stabilization remains obscure. The few reports regarding the use of steroids in myocardial ischemia have be

Previous researchers in powder compaction have been limited to pressures of about 1500 MN/m2, with 1000 MN/m2 being the more usual limit. This paper describes some compaction work performed at much higher pressures.

Asanguineous retroperfusion of the coronary sinus can penetrate a significant microvascular bed in proximity to myocardial cells. Myocardial regions permeated by this technique are located in the apex, septum, endocardium, and free wall of the left v
