The name of the family Polyomaviridae, derives from the early observation that cells infected with murine polyomavirus induced multiple (poly) tumors (omas) in immunocompromised mice.Subsequent studies showed that many members of this family exhibit the capacity of mediating cell transformation and tumorigenesis in different experimental models.The
Abstract Cortico-limbic brain activity associated with anger may be susceptible to nicotine and, thus, may contribute to smoking initiation and nicotine addiction.The purpose of the study was to identify the brain regions that are most reactive to nicotine and show the greatest association with anger task performance.Twenty adult nonsmokers (9 wome
This study discusses the heat exchange optimization of a 450 kW water heater operating with natural gas (NG) and in cofiring mode burning solid pulverized rumen and NG.The rumen material is a byproduct from cattle slaughter processes, consisting of the waste contained in the cow Mascara Primer stomachs and intestines.In NG mode, the gaseous fuel pr
To investigate the SEDs of galaxies considering the dust extinction processes in the galactic disks, we present the population synthesis models for normal galaxies with dusty disks.We use PEGASE (Fioc & Rocca-Volmerange 1997) to model them with standard input parameters for stars and new dust parameters.We find that the Jodhpur Clips model results
