The herbicide atrazine is one of the most commonly applied pesticides in the world. As a result, atrazine is the most commonly detected pesticide contaminant of ground, surface, and drinking water. Atrazine is also a potent endocrine disruptor that is active at low, ecologically relevant concentrations. Previous studies showed that atrazine adversely(More)
Cervical laminoplasty is a technique used to achieve spinal cord decompression in cases of myelopathy or myeloradiculopathy. The most common reason for failure of this technique is restenosis due to hinge closure. Various techniques have been employed to hold the laminar "door" open while the body heals the lamina hinge in the new expanded position.(More)
To portray aspen clonal and spatial genetic structures, we mapped and genotyped trees in two 1-ha plots, each containing three aspen cohorts originating from fire or subsequent secondary disturbances. We used four microsatellite loci to identify aspen clones and increment core analysis to determine tree age. Clonal dimensions were measured by the maximum(More)
BACKGROUND CONTEXT Eosinophilic granulomas (EGs) of the sacrum have been reported in fewer than 10 patients. Treatment algorithms for these tumors remain poorly defined; there are no reports of treating solitary sacral EG with radiation therapy (RT). PURPOSE This study aimed to describe the presentation, treatment, and outcome of sacral EG in an adult(More)
OBJECTIVES Adipose-derived mesenchymal stem cells (ADMSCs) are a unique population of stem cells with therapeutic potential in the treatment of connective tissue injuries. Growth differentiation factor-5 (GDF)-5 is known to play a role in tendon repair and maintenance. The aim of this study was to investigate the effects of GDF-5 on proliferation and(More)
PURPOSE In carotid artery disease, correlation of carotid plaque morphology with the patient's presenting symptoms has drawn conflicting conclusions. The purpose of this series was to correlate carotid plaque characteristics with the presenting symptoms from a large cohort of patients who underwent operation for carotid artery disease. METHODS From a(More)
Foxp3(+) regulatory T cells (T reg cells) effectively suppress immunity, but it is not determined if antigen-induced T reg cells (iT reg cells) are able to persist under conditions of inflammation and to stably express the transcription factor Foxp3. We used spleen cells to stimulate the mixed leukocyte reaction (MLR) in the presence of transforming growth(More)
All outpatient anterior cruciate ligament (ACL) reconstructions using patellar tendon autograft performed at an accredited outpatient surgical center between 1994 and 1998 were prospectively studied. Hospital charges pertaining to the procedures were examined, and perioperative morbidities that might be attributed to an outpatient procedure were evaluated.(More)
BACKGROUND A recent proposed modification in surgical technique in total knee arthroplasty (TKA) has been the introduction of the "kinematically aligned" TKA, in which the angle and level of the posterior joint line of the femoral component and joint line of the tibial component are aligned to those of the "normal," pre-arthritic knee. The purpose of this(More)
Preoperative planning for patient-specific guides (PSGs) in total knee arthroplasty (TKA) requires identification of anatomic landmarks on three-dimensional imaging studies. The aim of this study was to assess the accuracy and precision with which landmarks commonly used to determine rotational alignment in TKA can be identified on magnetic resonance(More)
