Análise da frequência alélica de 15 LOCI STR na população do Rio Grande do Norte

Human population have a significant number of polymorphic loci, whose use and applications range from construction of linkage maps, to study the evolution of populations, through the determination of paternity, forensic medicine and migration. Currently, STRs (Short Tanden Repeats) markers are considered the major markers for human identification, mainly due to its abundance and high variability because of the fact that they are easily amplifiable by PCR (Polymerase Chain Reaction), work with low amounts of DNA and be capable of automation processes involving fluorescence detection. The creation of regional databases containing allele frequencies of population provide subsidies to increase the reliability of the results of determining the genetic link. This paper aims to obtain a database of allele frequencies of 15 polymorphic molecular loci (D8S1179, D21S11, D7S820, CSF1PO, D19S433, vWA, TPOX, D18S51, D3S1358, TH01, D13S317, D16S539, D2S1338, D5S818 e FGA) in a population classifies as born in the State of Rio Grande do Norte, Brazil, totaling 1100 unrelated individuals. To evaluate the frequency, DNA samples were submitted to PCR amplification, followed by capilarry electrophoresis genetic sequencer. The frequencies identified in this study were compared with brazilian population in general and other states in Brazil. Except for the loci D21S11, D19S433 and D2D1338, the genotypes found were in Hardy-Weinberg equilibrium and no significant differences among the frequencies were found in the populations studied. The most informative loci was D2S1338 and D18S51, and the less informative is the locus TPOX

Reforma agrária de mercado e territorialização: um estudo a partir do Programa Cédula da Terra em Canindé-CE

The research Reforma Agrária de Mercado e Territorialização: um estudo a partir do Programa Cédula da Terra em Canindé-Ce , has an objective to discuss until whas time denominated agrarium refom has capacity of territory the of families in Five from the seven settlements cmated by resourles from the prgramme cell of earth em Canindé-Ce. In this context, the present work analysis the relation sitip between power and kind of identity, in special in those settlements, trying to learn the dialetic relationship. That passes by the process and appropriation in these spaces by these families gave the beginning of buying the land. The procedure methologic used by us gave privilege to realize the interview included in this process, wita the leaders of rural associations (STR); commission clero of earth (CPT); rural workers movement without land (MST); wita agricolas tecnics, and so the local coordinators of cell of earth in Fortaleza. The analysis of agrarium reform in Canindé, infects that the families giving entrance in buying the land, they could creatieg a hope in quality of life for getting the land. Nevertheless, it did not happen, in the rost of the parts of the areas in study. The territories present in general focus, the worse process of poomest besides the amount of debiths of these families, putting in risk the territorialization of themselves
