3. Comparison between hemosiderin and Technetium-99 in sentinel lymph node biopsy in human breast cancer
PURPOSE: To assess the safety and potential equivalence of the use of hemosiderin compared to the Technetium-99 in sentinel lymph node biopsy in human breast cancer. METHODS: Non-random sample of 14 volunteer women diagnosed with breast cancer with primary tumors (T1/T2) and clinically tumor-free axilla were submitted to the identification of sentinel lymp

4. Investigações de interações hiperfinas de DNA e anticorpos de diferentes linhagens de camundongos frente à infecção por T. cruzi pela espectroscopia de correlação angular gama-gama perturbada / Investigation of hyperfine interactions in DNA and antibody of different lineages of mice infected by T. cruzi by perturbed gamma-gamma angular correlation spectroscopy
In the present work perturbed angular correlation (PAC) spectroscopy was used to measured electric quadrupole interactions in DNA biomolecules of different mice lineages (A/J, C57BL/6, B6AF1, BXA1 e BXA2), samples of different isotypes of immunoglobulin G (IgG1, IgG2a e IgG2b) and active portions of complete and fragmented immunoglobulin responsible by the i

5. Impacto da presenÃa de atrazina na comunidade bacteriana do solo / Impact of atrazine on bacteriological soil community
Chemical contamination removal in soil and water depends on microbiological community that is able to degrade these compounds. There is a great evolutionary interest on studying microorganisms that metabolize the xenobiotic ones, since they have relatively been seen as new in the last five decades. Little is known about structure variation of microbiological

7. The impact of previous para-areolar incision in the upper outer quadrant of the breast on the localization of the sentinel lymph node in a canine model
OBJECTIVES: This paper discusses the influence of a para-areolar incision in the upper outer quadrant of the breast on the location of the sentinel lymph node in a canine model. METHODS: The sentinel lymph node was marked with technetium-99, which was injected into the subareolar skin of the cranial breast. After the marker had migrated to the axilla, an arc

8. Modelo Experimental em Caninos para a Pesquisa de Linfonodo Sentinela do EstÃmago / Experimental Model in Canines for Research Sentinel node Stomach
A gastrectomia com linfadenectomia ampliada ainda à o padrÃo ouro para o tratamento curativo do cÃncer de estÃmago (CaE), embora este procedimento possa levar a alto Ãndice de morbidade ou mortalidade, principalmente nos pacientes que nÃo apresentem disseminaÃÃo linfÃtica da doenÃa. A pesquisa do linfonodo sentinela (LS), jà consagrada nos tumores

9. New applications of radioguided surgery in oncology
OBJECTIVE: To report oncological cases (excluding those related to breast cancer) for which radioguided surgery has been used in combination with the Radioguided Occult Lesion Localization technique. INTRODUCTION: Radioguided surgery enables a surgeon to identify lesions or tissues that have been preoperatively marked with radioactive substances. The Radiogu

10. Estudo de Interações Hiperfinas em Óxidos RCoO3 (R= Gd e Tb) e Filmes Finos de HfO2 por Meio da Técnica de Espectrospia de Correlação Angular Gama- Gama Perturbada / Hyper¯ne Interaction Study in RCoO3 (R = Gd and Tb) and HfO2 thin ¯lm oxides by Perturbed Angular Correlation Technique
In the present work, the Perturbed Angular Gamma-Gamma Correlation technique (PAC) was used to measure the Electric Field Gradient (EFG) in two oxide systems: RCoO3 (R = Gd, Tb) perovskite oxide and HfO2 in order to study the behavior of the EFG as a function of temperature. Electric quadrupole hyper¯ne interaction measure- ments were carried out using 111I

11. PurificaÃÃo, caracterizaÃÃo de uma lectina e compostos fenÃlicos da entrecasca de Sebastiania jacobinensis (Muill. Arg.): efeito de radiaÃÃo gama sobre estrutura-atividade protÃica e proteÃÃo de flavonÃides isolados
A lectin from Sebastiania jacobinensis bark (SejaBL) was isolated using a combination of acetone precipitation, fractionation by ammonium sulphate, ion exchange and gel filtration chromatographies. The molecular mass of SejaBL was determined as approximately 52.0kDa by SDS-PAGE and 50.0kDa by gel filtration. The lectin is a glycoprotein with a neutral carboh

12. Desenvolvimento de sonda gama para cirurgia radioguiada
The use of intraoperative methods for guiding surgeries is increasing and is a promising method for improving the effectiveness of the surgical treatment of cancer. The procedure begins before surgery with the administration of a tumor-avid pharmaceutical that, usually, is labeled with a g-ray emitting radionuclide. During the subsequent surgical procedure,
