Thirty craniopharyngiomas were operated on between 1983 and 1993. Eight patients underwent surgery solely via the transsphenoidal route. None of these had undergone surgery previously. The eight patients were followed up for a period of 120 months (mean 87.5 months). The tumour was removed totally in five and subtotally in three patients. All eight patients(More)
OBJECTIVE To determine whether repeated use weakens titanium aneurysm clips, making them unsafe for clinical use. METHODS Nine Yaşargil (titanium alloy) and five Spetzler (pure titanium) clips were subjected to clinically relevant maneuvers, and the effects on the closing force were assessed. Clips were considered unsafe if 1) the blades crossed, 2) the(More)
INTRODUCTION In its broadest sense, intercultural competence can be defined following Fantini (2006) as " a complex of abilities needed to perform effectively and appropriately when interacting with others who are linguistically and culturally different from oneself " (p. 12, emphasis in original). Throughout the literature, researchers and theoreticians(More)
Studenl evaluations of college instruction provide one critical source of information for the improvement of courses, curriculum, and practitioners' pedagogic efforts. Increasingly, online-delivered course evaluations are being put to use for eliciting student feedback in Web-based as well as face-to-face courses. Two studies were conducted in order to,(More)
Miscanthus sacchariflorus is a fast-growing C(4) perennial grass that can naturally hybridize with M. sinensis to produce interspecific hybrids, such as the sterile triploid M.× giganteus. The creation of such hybrids is essential for the rapid domestication of this novel bioenergy crop. However, progress has been hindered by poor understanding of the(More)
Postclipping cerebral angiography is generally not practised in the UK. The International Subarachnoid Trial (ISAT) data show that coiling compared favourably with clipping in the early posttreatment phase. We present a 4-year, single unit experience comparing cerebral angiography at 6 months postclipping and postcoiling, defining the proportion of(More)
Recently published data from the International Subarachnoid Aneurysm Trial (ISAT) shows that for patients enrolled in the trial there is a 7.4% reduction in the incidence of death or dependency at 1 year if they undergo coiling, rather than clipping. Furthermore, extrapolation of longer-term follow-up data for patient mortality appears to suggest that this(More)
A neonate with a cerebral gliosarcoma was found to have chromosome abnormalities in tissue culture of the tumor, but normal karyotyping of peripheral blood. Similarities to and differences from chromosome abnormalities found in other human gliomas are noted. Unusual exposure of the child to heptachlor during prenatal development and the neonatal period(More)
