Doses e risco da radiação em pacientes submetidos a exames de corpo inteiro de 18F-FDG PET-CT para diagnóstico oncológico
(Universidade Federal de Minas GeraisUFMG, 2014-05-29)
Patients submitted to PET-CT examinations might be exposed to radiation levels, higher than those from other diagnostic techniques. The reason is that PET-CT complies two radiation exposures: one from the intravenous ...
Alterações em cinética temporal da expressão de proteínas plasmáticas in vivo e da viabilidade celular in vitro, induzidas pelas radiações ionizantes
(Universidade Federal de Minas GeraisUFMG, 2016-07-12)
Human existence on planet Earth has as one of its foundations adaptation of our body to radiation, such as solar and fund specific to each environment in which we live. So due to radiation exposure, our body has undergone ...
Avaliação de parâmetros da qualidade de imagem e dosimetria de pacientes submetidos a exames radiológicos de tórax
(Universidade Federal de Minas GeraisUFMG, 2012-06-21)
Optimization of procedures for obtaining high quality diagnostic images plays an important role for reducing radiation exposures of patients undergoing diagnostic radiology examinations to levels as low as reasonably ...
Estudos do papel do gene Rad51 de tripanossomatídeos na recombinação e no reparo de DNA
(Universidade Federal de Minas GeraisUFMG, 2010-11-09)
Trypanosoma cruzi is the etiologic agent of Chagas disease. This parasite can resist high doses of gamma radiation, a DNA double-strand breakinducing agent. To better understand this process, our group characterized the ...
Caracterização do perfil protéico e da atividade mitocondrial de Trypanosoma cruzi sob o estresse de radiação gama
(Universidade Federal de Minas GeraisUFMG, 2014-05-16)
The Trypanosoma cruzi is considered as one of the eukaryotes most resistant to ionizing radiation, enduring sub-lethal doses of up to 1.0 kGy. The ionizing radiation by gamma rays promotes double-strand and single-strand ...
Radionuclídeos naturais em minas subterrâneas brasileiras
(Universidade Federal de Minas GeraisUFMG, 2015-09-18)
Rock, soil and water contain 238U and 232Th and their decay products. The distribution of these radionuclides differs in terms of activity concentration depending on the mineral type and origin. All ore processing releases ...
Evaluation of Escherichia coli inactivation and sunlight penetration in a shallow maturation pond: hydrodynamics and disinfection
(Universidade Federal de Minas GeraisUFMG, 2016-08-24)
Maturation ponds can be used as post-treatment of anaerobic and aerobic reactors. They are widely used post-treatment units for treating wastewater in developing countries like Brazil because of their robustness and low ...
Análise da expressão gênica em Trypanosoma cruzi em resposta à radiação ionizante pela técnica de microarranjo de DNA
(Universidade Federal de Minas GeraisUFMG, 2011-03-10)
Among the various types of damages caused by ionizing radiation, the lesions of greatest biological importance are the double-stranded DNA breaks. The tolerance for this type of damage requires an efficient apparatus for ...
Avaliação das alterações do fluido crevicular gengival drenado de tecidos gengivais clinicamente normais submetidos à laser em baixa intensidade: estudo em anima nóbile
(Universidade Federal de Minas GeraisUFMG, 2008-07-04)
In periodontology the gingival tissue, peripheral blood flow and crevicular gingival fluid (which normally comes out of the gingival socket) are the most important immune barriers acting as defense mechanisms at the front ...
Estudos in vitro e in vivo de lipossomas contendo gadolínio-159 para o tratamento do câncer
(Universidade Federal de Minas GeraisUFMG, 2011-02-18)
In Brazil, estimates of new cancer cases, valid for the years 2010 and 2011 show that the disease will be responsible for the deaths of about 500,000 people. As an alternative therapythe radiotherapy technique, widely used ...
