The relationship between relative force, electromyogram (EMG) and time to fatigue was examined in seven male and seven female subjects [mean (SD) age, 21.7 (3.2) years] during isometric handgrip exercise. Subjects performed sustained submaximal contractions of the right handgrip at three different intensities: 30%, 50%, and 75% of the pretrial maximum(More)
Purpose. The purpose of this study was to develop and validate an animal model of drug disposition in synovial fluid (SF) by comparing microdialysis with arthrocentesis using the anti-arthritic drug methotrexate (MTX). Methods. Microdialysis probes were calibrated in vitro with the no net flux method using dog synovial fluid. The probes were implanted(More)
Alzheimer's Disease (AD) is a progressive neurodegenerative disorder characterized by an excessive production of extracellular amyloid plaques and intracellular neurofibrillary tangles in the brain. Studies have shown that concentrations of tau and amyloid protein (β-amyloid (Aβ)) are altered in the cerebrospinal fluid (CSF) of patients with AD. In an(More)
OBJECTIVE To analyse all the cases of ameloblastoma seen in the two major public Hospitals in Jamaica over a 16-year period, and to compare the results with what has been previously documented by other authors in the literature. A new treatment modality for prevention of recurrence of ameloblastoma is described. SUBJECTS AND METHODS The case files of(More)
There is little information concerning the incidence of alveolar bone loss in estrogen-deficient women. Ovariectomized sheep are valid models for study of the effects of estrogen deficiency on bone metabolism. The objective of this study was to compare alveolar bone loss in control (C) and ovariectomized sheep (OVX) at 3 and 12 months following surgery. OVX(More)
Eleven consecutive patients with small cell carcinoma of the lung treated intensively with a combination chemotherapy regimen cyclophosphamide, Adriamycin, VP-16, and vincristine experienced peripheral neuropathy. Four of the 11 patients had severe (Grade III) neuropathy, leaving them virtually bedridden; the remaining seven patients had mild to moderate(More)
Data were collected prospectively on 57 Jamaican children presenting with 62 episodes of acute intussusception over a two year period, for whom operative and hydrostatic methods of reduction were employed. 31 (54%) of 57 episodes were reduced successfully using barium (42), saline (11) and air (4) hydrostatically. Among the 31 other episodes, 15 had(More)
In a two-year follow-up on sixteen total shoulder arthroplasties done with the semiconstrained Stanmore prosthesis, we found that patients with rheumatoid arthritis or osteoarthritis of the glenohumeral joint noted a greater relief of pain, were more satisfied with their surgery, used fewer analgesics, and had a greater increase in range of motion than(More)
