| Cd and V were analyzed in planktonic species (zooplankton and diatoms), in flocks and in total seston (suspended materials) collected at eleven stations for seven sampling periods in the eastern area of the bay of Seine. Cd concentrations measured in planktonic species of the bay of Seine are identical to those measured in other oceanic areas, but V concentrations are generally higher. In the conditions of sampling, the role of both planktonic species and flocks in the horizontal fluxes of Cd and V in the bay of Seine appears not to be important (Cd) or negligible (V) compared to non-living materials (tripton). Nevertheless, this study should be continued in periods of diatom blooms. Flocks which present high Cd and V concentration probably have an... |

| We investigated the levels of F and its relationship with As, B and V in ground and surface waters of the southern Pampas, where cases of dental and skeletal fluorosis, and arsenic in hair and urine samples have been detected in the rural population. Eating vegetables and cereals grown in irrigated areas with excessive fluoride may increase the risk of fluorosis due to the addition of the extra F contributed from other sources such as drinking water. Moreover, if these elements exceed the tolerance of crops produce toxicity and, like salinity, they decrease the potential crop yield. Within an area of 2300 km², 81 samples were taken from surface and groundwaters to determine F, As, B and V. Fluoride was detected in 86% of the sampled groundwaters, and in... |

| Human Cytomegalovirus (HCMV) is a herpesvirus associated with serious diseases in immunocompromised subjects. The region between ORF UL133 and UL151 from HCMV, named ULb' is frequently deleted in attenuated AD169 and in highly passaged laboratory strains. However, this region is conserved in low-passaged and more virulent HCMV, like the Toledo strain. The UL146 gene, which is located in the ULb' region, encodes a CXC-chemokine analogue. The diversity of UL146 gene was evaluated among fifty-six clinical isolates of HCMV from Japan. Results show that UL146 gene was successfully amplified by the polymerase chain reaction (PCR) in only 17/56 strains (30%), while the success rate for UL145/UL147 gene was 18/56 strains (32%). After DNA sequencing, the 35... |
