We examined the relationship between circulating levels of gonadal steroids (testosterone, progesterone, and estradiol) and breeding behavior in semipalmated sandpipers (Calidris pusilla) and red-necked phalaropes (Phalaropus lobatus) breeding sympatrically at La Pérouse Bay, 40 km east of Churchill, Manitoba. Semipalmated sandpipers are territorial and(More)
Growth arrest-specific gene 6 (Gas6), identified in 1995, acts as the ligand to the Axl/Tyro3 family of tyrosine kinase receptors and exerts mitogenic activity when bound to these receptors. Overexpression of the Axl/Tyro3 receptor family has been found in breast, ovarian and lung tumours. Gas6 is upregulated 23-fold by progesterone acting through the(More)
Thirty-six patients with multiple myeloma (23 PR1, nine PR2, four stable disease) were entered into a pilot study evaluating the use of CD34+-selected peripheral blood progenitor cell transplantation (PBPCT) following high-dose melphalan alone or high-dose melphalan and total body irradiation. Peripheral blood progenitor cells (PBPCs) were mobilized with(More)
Friedreich's ataxia (FRDA) has been associated with both cardiac hypertrophy and to a lesser degree dilated cardiomyopathy. We have conducted a cross sectional magnetic resonance imaging (MRI) study of 25 patients with clinically and genetically confirmed FRDA and 24 healthy controls to analyse how disease parameters influence cardiac features in FRDA. MR(More)
Cell lines RPMI 8226, JJN3, U266 B1, NCI-H929 (all EBV-) and ARH77 and HS-Sultan (both EBV+) have been extensively characterized in this study. EBV- lines expressed the phenotype (CD138-, CD19+, CD20+) whereas EBV+ were (CD138+, CD19-, CD20-). CD56 expression was restricted to EBV- cell lines, with the exception of U266 B1, whereas PCA-1 was strongly(More)
Internal herniation is a well-described complication after a gastric bypass, particularly when performed laparoscopically, although it is rarely described following a total gastrectomy. A 55-year-old lady presented with a 24-hour history of vomiting and rigors 10 months after a radical total gastrectomy with Roux-en-Y reconstruction for a gastric(More)
Placement of a self-expanding metal stent (SEMS) in patients presenting with colorectal cancer as an acute large bowel obstruction may obviate emergency surgery, potentially effectively palliating incurable cancers and acting as a bridge to surgery in patients with operable tumours. We present our experience with stenting for malignant acute large bowel(More)
We created unstable intertrochanteric fractures with a large posteromedial defect in eighteen pairs of fresh-frozen femora from cadavera, and used the femora to evaluate the stability of six combinations of treatment with sliding compression screws and sideplates. The variables that were tested were high (150-degree) angle plates compared with low(More)
