BACKGROUND Vertebroplasty is commonly used to treat painful, osteoporotic vertebral compression fractures. METHODS In this multicenter trial, we randomly assigned 131 patients who had one to three painful osteoporotic vertebral compression fractures to undergo either vertebroplasty or a simulated procedure without cement (control group). The primary(More)
Phenotypically wingless (ws) chick embryos have wing buds characterized by the spreading of mesenchymal cell death in an anterior-to-posterior direction beginning at stage 19. It has been argued that this may reflect the absence of a functional polarizing zone (ZPA). When tested by preaxial grafting into normal wing buds (stages 20-21), wingless ZPAs (stage(More)
In this article the use of somatic cell counts for monitoring udder health and milk quality is discussed. Somatic cell count dynamics at quarter, cow, herd and population level are discussed and illustrated with examples. Quarter and cow somatic cell counts directly represent the inflammatory status of the mammary gland. Herd and population somatic cell(More)
The Strengthening Washington DC Families Project (SWFP) examined implementation fidelity and effectiveness when a selective, evidence-based prevention program was implemented with a sample of 715 predominantly African American families across multiple settings in an urban area. Using a true experimental design, this study reports on the differential(More)
PURPOSE To compare serial optic nerve head (ONH) histology with interpolated B-scans generated from a three-dimensional (3-D) spectral domain (SD)-OCT ONH volume acquired in vivo from the same normal monkey eye. METHODS A 15 degrees ONH SD-OCT volume was acquired in a normal monkey eye, with IOP manometrically controlled at 10 mm Hg. After perfusion(More)
Optimal phototransduction requires separation of the avascular photoreceptor layer from the adjacent vascularized inner retina and choroid. Breakdown of peri-photoreceptor vascular demarcation leads to retinal angiomatous proliferation or choroidal neovascularization, two variants of vascular invasion of the photoreceptor layer in age-related macular(More)
The use of apoptosis-inducing agents in the treatment of malignant cancer is increasingly being considered as a therapeutic approach. In this study, the induction of apoptosis and necrosis was examined in terms of temporal dose responses, comparing a malignant and nonmalignant breast cell line. Staurosporine (SSP)-induced apoptosis and H(2)O(2)-induced(More)
PURPOSE To provide an initial assessment of the safety of a recombinant adeno-associated virus vector expressing RPE65 (rAAV2-CB-hRPE65) in adults and children with retinal degeneration caused by RPE65 mutations. DESIGN Nonrandomized, multicenter clinical trial. PARTICIPANTS Eight adults and 4 children, 6 to 39 years of age, with Leber congenital(More)
PURPOSE Cell-based therapy rescues retinal structure and function in rodent models of retinal disease, but translation to clinical practice will require more information about the consequences of transplantation in an eye closely resembling the human eye. The authors explored donor cell behavior using human cortical neural progenitor cells (hNPC(ctx))(More)
Visual phenomena are frequently reported in patients after ocular trauma, surgery or progressive visual degeneration. In particular, hallucinations are often seen by patients following enucleation. Whereas these visions can be verbally described to the physician, they can never actually be seen. This article focuses on the case of a female artist who(More)
