    Notes: Abstract Local intra-arterial fibrinolysis (LIF) is the best choice at present for treatment of acute vessel occlusion in the vertebrobasilar territory and also, in selected cases, in the carotid territory. In almost all cases angiography demonstrates the site of occlusion exactly and gives information about collateral circulation. Contrary to this common approach, we report five patients with severe acute thromboembolic stroke in whom angiography revealed no occlusion of relevant arteries or their main branches. Under the hypothesis of persisting occlusion of perforating arteries to the brain stem we performed LIF in patients with a clinical basilar artery syndrome. Outcome in all but one of them was good following LIF. The clinical details are described and possible reasons discussed.

    Notes: Abstract. Structural imperfections in synthetic diamond single crystal prepared under high temperature and high pressure (HPHT) in the presence of a Fe65Ni35 catalyst have been examined with transmission electron microscopy (TEM) and moiré patterns. The existence of stacking faults, concentric dislocation loops and an array of dislocations in the diamond was suggested. The formation mechanism of these structural imperfections was analyzed briefly. It was found that the structural imperfections originate from an excess amount of saturated vacancies and internal stresses associated with inclusions in the diamond.
