There has been no study about the presence of EBV in gastric adenocarcinoma in Iran. Methods: We examined the presence of EBV in 273 formalin fixed paraffin-embedded cases of gastric carcinoma from Cancer instit...
متن کاملThe Black Sea in crisis.
Background. DNA adenine methylation plays an important role in several critical bacterial processes including mismatch repair, the timing of DNA replication and the transcriptional control of gene expression. The dependence of bacterial virulence on DNA adenine methyltransferase (Dam) has led to the proposal that selective Dam inhibitors might function as broad spectrum antibiotics. Methodology...
متن کاملAnaerobic methane oxidation in Black Sea sediments
Anaerobic oxidation of methane (AOM) and sulfate reduction (SRR) were investigated in sediments of the western Black Sea, where methane transport is controlled by diffusion. To understand the regulation and dynamics of methane production and oxidation in the Black Sea, rates of methanogenesis, AOM, and SRR were determined using ra-5 diotracers in combination with pore water chemistry and stable...
متن کاملStatus of the Black Sea Flood Hypothesis
Exploration of the Black Sea shelf reveals two major shelf-crossing unconformities. The older unconformity separates mostly-barren deposits of late glacial age from overlying Neoeuxinian sediment containing fresh to brackish fauna. This unconformity can be traced over the shelf edge to depths beyond –140 m. The substrate below is dry, firm, and contains unchallenged evidence of subaerial exposu...
متن کاملIOWBSRC Workshop on Black Sea Fluxes
The rivers are the main sources both of sediments and pollutants. Their irregular supply from different catchment areas controls the nature of terrigenous sedimentation and contamination of the Black Sea. The role of aerosols in the Black Sea has not yet been estimated. As a result of studies in the Black Sea pre-Caucasian zone, it is revealed that fluxes of sediments and pollutants display a w...
