ABSTRACT
O estudo teve como objetivo identificar e comparar os resultados de glicemia de pacientes adultos com diabetes tipo 2 por meio de duas técnicas, laboratorial e capilar. Estudo comparativo foi desenvolvido no período de setembro a dezembro de 2007. A população foi constituída de 36 pacientes adultos residentes no município de Planaltina do Paraná, PR. A pesquisa foi realizada no laboratório de análises clínicas municipal. Para o exame laboratorial foi usado o sangue venoso e para o teste capilar o sangue da ponta do dedo. A maioria dos pacientes (63,9%) era do gênero feminino, idade média de 62,4 anos. Quanto à escolaridade, 41,6% dos pacientes possuíam menos de 8 anos de estudo. Em relação aos níveis glicêmicos, o p-valor do teste Kappa foi significativo em todas as categorias (p< 0,001, p=0,005 e p=0,001), mostrando concordância. Os dados indicam elevada precisão e acurácia dos resultados de glicemia obtidos por meio do glicosímetro, quando comparada ao teste padrão obtido em laboratório.
The goal of this research was to measure the blood glucose levels of type 2 diabetic adult patients and compare the results obtained by two techniques, the standard laboratory (venous) and portable glucometer (capillary) tests. A comparative longitudinal study was conducted from September to December 2007. The study population consisted of 36 resident adult patients in the town of Planaltina do Paraná in upstate Paraná, Brazil. The tests were performed in the local health authority clinical laboratory. For the lab test, venous blood from the arm was used, and for the glucometer test, capillary blood from the fingertip. Most of the patients (63.9%) were women and the average age was 62.4 years. Regarding education, 41.6% of the patients had studied for less than 8 years. Comparing the glucose measurements, the results of the Kappa test were significant in all categories (p<0.001, p=0.005 and p=0.001), showing very good agreement between the methods. The findings indicate a high level of precision and accuracy for the blood glucose readings obtained with the glucometer, compared with the standard test carried out in the laboratory.

Chloroplast cyt b6f complexes as well as mitochondrial and bacterial cyt bc1 complexes contain a high potential Rieske iron-sulfur protein which is essential for their function. To characterise the isolated Rieske protein from the mesophilic cyanobacterium Synechocystis PCC6803 we cloned the encoding gene into an expression vector and overexpressed the protein in E. coli. In cells overexpressing the protein no typical Rieske type EPR signal was detected neither in membranes nor in inclusion bodies where the majority of the protein was deposited. The inclusion bodies were isolated from the E. coli cells and denaturated with 8 M urea. With a single anion exchange chromatographic step a pure protein could be obtained which was used for further experiments. The NifS like protein IscS was recently reported to mediate the incorporation of iron-sulfur clusters into ferredoxin in vitro. We used the recombinant IscS protein for the incorporation of the cluster into the folded Rieske apoprotein. Spectroscopic characterisation of the resultant protein by CD and EPR spectroscopy showed the presence of a typical Rieske iron-sulfur centre.
