Children and adults were tested on 3 place learning tasks. Children under the age of 7 were inferior to older subjects in solving the tasks by using spatial relational solutions, but subjects of all ages were equally proficient in solving the task by using simple stimulus-reward associations (cued solutions). Accurate performance on the cued versions(More)
OBJECTIVE To assess the numbers of men in outpatients and subsequently undergoing transurethral resection of the prostate (TURP) who were referred during 1993-94 and 1996-97, thereby assessing the feasibility of a subsequent study of treatment efficacy in men with bladder outlet obstruction secondary to benign prostatic hyperplasia, prospectively randomized(More)
To investigate the ontogenesis of oddity learning, children (16 to 102 months of age) and adults were tested on two versions of the oddity task using non-verbal procedures originally developed for monkeys. On the standard, "one-part" or "simultaneous" oddity task (Experiment 1), young children (16 to 74 months of age) performed more poorly than older(More)
A canine small bowel allograft model was used to determine the effects of radiation to the graft in modifying the immunological effects of the passenger leukocytes. When untreated allografts were transplanted, death of the recipient animals occurred at a mean of nine days. The allograft was well-preserved and showed no signs of rejection. The reasons for(More)
OBJECTIVE To assess the efficiency of a prostate clinic and to determine the treatment outcomes and the proportion of patients who could potentially be managed by their General Practitioners (GPs). PATIENTS AND METHODS Referral letters from GPs were screened by the consultant urologists and appropriate patients seen in the next available prostate clinic.(More)
Virtual reality (VR) offers a great new perspective on what it can offer an individual. These new approaches can give an individual the immersion and cognitive guidance that they need to help overcome his or her disorder. VR differs from the traditional displays in computer graphics as these various displays are integrated to give the user a sense of(More)
Preoperative intra-individual variation for determinations of prostate-specific antigen and prostatic acid phosphatase concentrations, 15-30% in 92 patients with benign prostatic hyperplasia, limits the diagnostic usefulness of both tumor markers. In benign prostatic hyperplasia (214 patients), concentrations of these tumor markers increased in the initial(More)
