Of 68 patients undergoing microsurgical operations for ruptured lumbar discs, 33 were treated by removing only the herniated fragments. In the remaining 35, an attempt was made to remove the entire disc. No recurrences followed the more extensive discectomies during follow-up periods varying from 11 to 30 months. Seven recurrences followed operations in(More)
Molecular dynamics (MD) simulations of phosphatidylinositol (4,5)-bisphosphate (PIP2) and phosphatidylinositol (3,4,5)-trisphosphate (PIP3) in 1-palmitoyl 2-oleoyl phosphatidylcholine (POPC) bilayers indicate that the inositol rings are tilted approximately 40 degrees with respect to the bilayer surface, as compared with 17 degrees for the P-N vector of(More)
170 symptom-free homosexual men were recruited in London in 1982-83 and 133 were evaluable in 1983-85. Of the 33 who were seropositive to HTLV-III/LAV at entry, 4 (12%) progressed to AIDS, 16 (48%) progressed to persistent generalised lymphadenopathy (PGL), and 13 (40%) remained symptom-free. A further 15 men seroconverted during the study (7% per annum),(More)
Two episodes of massive bleeding from a sutured arteriotomy were observed within 30 hours after carotid endarterectomy. The patient had received anticoagulation therapy with heparin for 72 hours prior to surgery. A platelet count of 93,000/cu mm was demonstrated following the second hemorrhage. The potential problem of drug-induced thrombocytopenia(More)
The author describes the surgical treatment of 14 patients in whom angiography demonstrated total occlusion of the internal carotid artery (ICA) associated with stenosis at the origin of the ipsilateral external carotid artery (ECA). Each patient underwent ECA endarterectomy followed by an angioplasty to enlarge the ECA outflow tract by incorporating the(More)
