Genotoxic effect of high nitrate water consumption in men and woman from northern Mar del plata, Argentina

Previous research has shown connections between the exposure to different agents and mutations in germinal and somatic cells. One of such agents, nitrate (NO3), can be potentially genotoxic for individuals who drink high nitrate well water, and may cause a subsequent impact on their health and on the whole ecosystem. The aim of this research was to conduct genotoxicity assays in somatic cells from people living in the northern area of Mar del Plata city, Argentina. The purpose of these experiments was, in turn, to establish the possible relationships between mutagenic effects and high nitrate water consumption. To this end, different diagnostic tests were carried out to detect potential genetic and/or chromosomal alterations. A non-exposed population equal...

Genetic structure and demographic history of striped weakfish Cynoscion guatucupa (sciaenidae) from the southwestern atlantic
Provedor de dados: 46
Autores: Alonso,M.P; Fernández Iriarte,P.J.
In South America, the Pleistocene was characterized by important environmental changes related to glacial cycles, which had significant effects on the evolutionary history of several marine species. To evaluate the pattern of demographic history and the genetic structure of striped weakfish Cynoscion guatucupa, a 401 bp fragment of the mitochondrial Cytochrome b gene was sequenced from 92 individuals from three coastal areas in Argentina and one in Brazil in the southwestern Atlantic. Haplotype diversity was high, whereas nucleotide diversity was low among all sampling sites. The star-like pattern was not phylogeographically structured, in agreement with the AMOVA analysis. The Fu&amp;#8217;s test was negative and highly significant whereas the mismatch...
