The prostate-specific antigen test has been a major factor in increasing awareness and better patient management of prostate cancer (PCA), but its lack of specificity limits its use in diagnosis and makes for poor early detection of PCA. The objective of our studies is to identify better biomarkers for early detection of PCA using protein profiling(More)
BACKGROUND In patients with acute stroke, rapid intervention is crucial to maximise early treatment benefits. Stroke patients commonly have their first contact with medical staff in the emergency room (ER). We designed and validated a stroke recognition tool-the Recognition of Stroke in the Emergency Room (ROSIER) scale-for use by ER physicians. METHODS(More)
PURPOSE Prostate cancer gene 3 (PCA3) has shown promise as a molecular marker in prostate cancer detection. We assessed the association of urinary PCA3 score with prostatectomy tumor volume and other clinical and pathological features. MATERIALS AND METHODS Urine specimens were collected after digital rectal examination from 59 men scheduled for prostate(More)
BACKGROUND AND PURPOSE Timely referral of appropriate patients to acute stroke units is necessary for effective provision of skilled care. We compared the characteristics of referrals with suspected stroke to an academic acute stroke unit via 3 primary referral routes: ambulance paramedics using a rapid ambulance protocol and stroke recognition instrument,(More)
We present a method of data reduction using a wavelet transform in discriminant analysis when the number of variables is much greater than the number of observations. The method is illustrated with a prostate cancer study, where the sample size is 248, and the number of variables is 48,538 (generated using the ProteinChip technology). Using a discrete(More)
This study, designed and conducted as part of the International Life Sciences Institute working group on the Application of Genomics and Proteomics, examined the changes in the expression profile of genes associated with the administration of three different nephrotoxicants--cisplatin, gentamicin, and puromycin--to assess the usefulness of microarrays in(More)
OBJECTIVE Herein we report our experience of 49 consecutive pyeloplasties that were all laparoscopically performed with an intracorporeally sutured anastomosis. We describe the operative technique, complications and outcomes during a follow-up period of 1-53 months (mean 23.2 months). PATIENTS AND METHODS Forty-nine patients (28 women and 21 men) with a(More)
The purpose of this study was to determine whether aspirin could prevent a decrease in the platelet aggregate ratio that we previously found after cigarette smoking. Twenty healthy nonsmokers, who had not taken aspirin in the preceding seven days, smoked two tobacco cigarettes without filters during a 20-minute period. The mean platelet aggregate ratios(More)
After abstinence for at least 8 hours, 20 healthy habitual smokers smoked two unfiltered cigarettes during each of two 20-minute periods separated by 48 hours. They had taken one 0.32-g tablet of acetylsalicylic acid (ASA) the night before the second period. The mean platelet aggregate ratios in venous blood taken immediately before and after each period of(More)
