BACKGROUND The thalamus is a brain region of interest in the study of schizophrenia because it provides critical input to brain regions such as the prefrontal, cingulate, and temporal cortices, where abnormalities have been repeatedly observed in patients with schizophrenia. Postmortem anatomic studies have rarely investigated the thalamus in this(More)
Vascular endothelial growth factor, fibroblast growth factor (FGF), and platelet-derived growth factor (PDGF) and their cognate receptor tyrosine kinases are strongly implicated in angiogenesis associated with solid tumors. Using rational drug design coupled with traditional screening technologies, we have discovered SU6668, a novel inhibitor of these(More)
Receptor tyrosine kinases (RTKs) have been implicated as therapeutic targets for the treatment of human diseases including cancers, inflammatory diseases, cardiovascular diseases including arterial restenosis, and fibrotic diseases of the lung, liver, and kidney. Three classes of 3-substituted indolin-2-ones containing propionic acid functionality attached(More)
The combustion of high fluoride-content coal as an energy resource for heating, cooking, and food drying is a major exhaust emission source of suspended particulate matter and fluoride. High concentrations of these pollutants have been observed in indoor air of coal-burning families in some rural areas in China. Because airborne fluoride has serious(More)
There are currently no therapies to restore vision to patients blinded by photoreceptor degeneration. This project concerns an experimental approach toward a semiconductor-based subretinal prosthetic designed to electrically stimulate the retina. The present study describes surgical techniques for implanting a silicon microphotodiode array in the cat(More)
After screening a bacterial artificial chromosome of human genomic DNA library with human HS-40, zeta-, alpha-, and theta-globin probes, a 110-kb clone bearing the whole human alpha-globin gene cluster was obtained and rare restriction endonuclease mapping was performed. The bacterial artificial chromosome DNA was isolated, and transgenic mice were(More)
Connexin26 (Cx26, GJB2) mutations account for >50% of nonsyndromic hearing loss. The deafness is not always congenital. A large group of these patients (∼30%) demonstrate a late-onset hearing loss, starting in childhood. They have normal hearing early in life and are therefore good candidates for applying protective and therapeutic interventions. However,(More)
OBJECTIVE To determine the transmission rate of human papillomavirus (HPV) in newborn infants of HPV-positive women and to assess the relationship between perinatal HPV transmission and mode of delivery. METHODS Three hundred one pregnant women were selected: vaginal delivery (n = 160) or cesarean delivery (n = 141). We assessed the presence of the HPV(More)
Angiogenesis, or the sprouting of new blood vessels, is a central process in the growth of solid tumors. For many cancers, the extent of vascularization of a tumor is a negative prognostic indicator signifying aggressive disease and increased potential for metastasis. Recent efforts to understand the molecular basis of tumor-associated angiogenesis have(More)
The BALB/c mouse model of Niemann-Pick type C disease exhibits similar neuropathological features to the human condition, including cerebral atrophy, demyelination of the corpus callosum, and degeneration of cerebellar Purkinje cells. The gene defect in Niemann-Pick C disease causes cholesterol to accumulate within the lysosomal compartment of neurons and(More)
