Detection of a low frequency of activated ras genes in human melanomas using a tumorigenicity assay.
We have used an assay combining DNA-mediated gene transfer and tumorigenicity in Swiss athymic mice to look for activated ras genes in solid human sporadic melanomas. This assay can detect ras oncogenes mutated at codons 12, 13, or 61. We examined a panel of 13 independent surgical specimens of primary tumors and metastases. No H- or K-ras oncogenes were detected; an N-ras oncogene, mutated at ...

Models of economic geography predict that transportation costs directly affect demand for goods and the supply of intermediate inputs. One of the reasons that international trade is concentrated in the coastal provinces of China is that they have lower transportation costs in transporting goods to other countries than do provinces in the interior. This paper examines the relationship between th...
Synaptogenesis, the formation of functional synapses, is a crucial step for the development of the central nervous system. Among the genes involved in this process are cell adhesion molecules, such as protocadherins and neuroligins, which are essential factors for the identification of the appropriate partner cell and the formation of synapses. In this work, we studied the expression and the ge...
We used a novel experimental setup to conduct the first synchrotron-based (61)Ni Mössbauer spectroscopy measurements in the energy domain on Ni coordination complexes and metalloproteins. A representative set of samples was chosen to demonstrate the potential of this approach. (61)NiCr2O4 was examined as a case with strong Zeeman splittings. Simulations of the spectra yielded an internal magnet...
Introduction: [61Cu]diacetyl-bis(N4-methylthiosemicarbazone) ([61Cu]ATSM) is a well-established hypoxia imaging tracer with simple production and significant specifity. In this work the accumulation of the tracer is studied in wild-type, necrotic and hypoxic fibrosarcoma tumors. Methods: [61Cu]ATSM was prepared u...
Background Hypogammaglobulinemia (HGGS) is one of the adverse effects Rituximab (RTX), a chimeric monoclonal antibody directed against CD20 receptor, frequently observed in ANCA-associated vasculitis (AAV) patients. Objectives To study characteristics patients with AAV on RTX treatment and to analyze factors associated HGGS, as well compare them rheumatoid arthritis (RA) same treatment. Methods...
Background and Aim: Bacterial infection is common after acute variceal bleed (AVB) in patient with cirrhosis associated higher re-bleed mortality rate. Antibiotics prophylaxis ceftriaxone recommended AVB. Aim of this study was to evaluate incidence bacterial AVB during hospital stay even antibiotic prophylaxis. Methods: Retrospective analysis data patients who were on antibiotics from day 1 adm...
