We tested the hypothesis that the DYT1 genotype is associated with a disorder of anatomical connectivity involving primarily the sensorimotor cortex. We used diffusion tensor magnetic resonance imaging (DTI) to assess the microstructure of white matter pathways in mutation carriers and control subjects. Fractional anisotropy (FA), a measure of axonal(More)
Deep brain stimulation of the subthalamic nucleus (STN DBS) has become an accepted tool for the treatment of Parkinson's disease (PD). Although the precise mechanism of action of this intervention is unknown, its effectiveness has been attributed to the modulation of pathological network activity. We examined this notion using positron emission tomography(More)
Four cases of baclofen intoxication are reported, with a review of 33 cases from the literature. Analysis of these 37 cases suggests that there are two types of baclofen intoxication syndrome. Patients with acute intoxication present with four major clinical manifestations: encephalopathy (disturbance of consciousness and/or seizure), respiratory(More)
Surface hip replacement (SHR) is generally used in younger, active patients as an alternative conventional total hip replacement in part because of the ability to preserve femoral bone. This major benefit of surface replacement will only hold true if revision procedures of SHRs are found to provide good clinical results. A retrospective review of SHR(More)
Total hip arthroplasty is associated with extensive blood loss, which is often corrected using allogeneic blood transfusions. However, Jehovah's Witnesses often refuse allogeneic blood transfusions or certain types of autologous blood transfusions due to their religious beliefs. This may represent a tremendous challenge for the orthopaedic surgeon and their(More)
OBJECT Short-term benefit from unilateral subthalamotomy for advanced Parkinson disease (PD) is associated with metabolic alterations in key targets of subthalamic nucleus (STN) and globus pallidus (GP) output. In this study positron emission tomography (PET) scanning was used to assess these changes and their relation to long-term benefits of(More)
We sought to examine the amount of bone removed during total hip arthroplasty with a resurfacing femoral component, compared to with a conventional, stemmed femoral component, by using 6 male and 4 female cadaveric pelves with attached bilateral proximal femora. Using randomized assignment and order, a total hip arthroplasty with a resurfacing femoral(More)
The asexual erythrocytic stage of Plasmodium falciparum was grown in culture in the presence or absence of glycoconjugate polyanions of varying structure, size and substitutions. Heparin, dextran sulfate, fucoidan and pentosan polysulfate had antimalarial IC50 values between one and 11 microg ml(-1). Constituent heparin disaccharides were ineffective(More)
Glycophorin A is a major receptor on human erythrocytes for Plasmodium falciparum, the human malaria parasite. In this work, we have produced four glycophorin A-specific mAb: 2B10, 1E4, 3H12, and 3H2. 2B10 was mapped to the amino terminal region of glycophorin (amino acids 1-31), and its binding to erythrocytes was fully dependent on sialic acid residues.(More)
Oral squamous cell carcinoma is a common neoplasm that is known to be causally associated with genetic factors and environmental carcinogens. The receptor for advanced glycosylation endproducts (RAGE) is a transmembrane protein of the immunoglobulin superfamily with broad specificity for multiple ligands, and it has been shown to play vital roles in several(More)
