Atypical alveolar hyperplasia (AAH) is a potential precursor lesion from which lung adenocarcinomas arise and may be a good target for studying the early events of lung tumorigenesis. A common genetic alteration in lung adenocarcinomas is mutational activation of K-ras. To determine the timing of K-ras activation, we evaluated formalin-fixed and(More)
We report a case of juxtaposed atypical meningioma and meningioangiomatosis (MA) in an 8-year-old boy with no clinical stigmata or family history of neurofibromatosis. We studied the proliferative activity and genetic changes in the two lesions in an attempt to define their biologic and pathogenetic relationships. The MIB-1 index was 11% in the meningioma(More)
BACKGROUND Fibroblast growth factors (FGFs) play important roles in multiple cancers by supporting tumor growth and angiogenesis. FP-1039 (GSK3052230) is a FGF ligand trap consisting of the extracellular domain of FGF receptor 1 (FGFR1) fused with the Fc region of IgG1. FP-1039 binds and neutralizes multiple FGFs that normally bind FGFR1. The primary(More)
We have examined melanocytic cells derived directly from fresh biopsy tissue for the presence of p53 mutations. Using selective media that permits growth of melanocytes and inhibits growth of fibroblasts and keratinocytes, we established short-term, primary cultures of melanocytes from skin biopsies of common acquired nevi, dysplastic nevi, and from(More)
STUDY BACKGROUND Dental amalgam is still widely used as a restorative material in developing countries due to its low cost and ease of manipulation. The health risks associated with the components of this restorative material has always been a matter of concern. Our study was designed to address this question regarding dental amalgam. OBJECTIVE To study(More)
Sister chromatid exchange (SCE) test is a sensitive, biomarker of genotoxic substances. The frequency of SCE in lymphocytes of ten pan chewing patients, oral submucous fibrosis (OSF) patients and age matched healthy controls were investigated. The frequency of mean SCE/cell was found to be 10.428 ± 0.755 in OSF patients, 8.752 ± 0.383 in case of pan chewers(More)
