1. Overall survival prediction in metastatic castration-resistant prostate cancer treated with radium-223
ABSTRACT Objective Radium-223(223Ra) is indicated for patients (p) with metastatic castration resistant prostate cancer (mCRCP). Objectives The aim of this study was to evaluate the role of baseline clinical variables associated with overall survival (OS) and toxicity of 223Ra. Its purpose was to identify the factors that can predict a better response to

2. Editorial Comment: Overall survival prediction in metastatic castration-resistant prostate cancer treated with radium-223
ABSTRACT Objective and Hypothesis We aimed to investigate the reasons of storage symptoms ( SS) after transurethral resection of the prostate (TURP). The hypothesis was that a positive correlation would be identified between preoperative and postoperative SS in patients with undergoing TURP and starting early solifenacin treatment in patients with high pre

5. Baseline and Quality Reference Values for Natural Radionuclides in Soils of Rio de Janeiro State, Brazil
ABSTRACT A first large-scale systematic survey of natural radioactivity contents of soils of the state of Rio de Janeiro is presented, focused on the establishment of Quality Reference Values (QRVs). Undisturbed soil samples were collected from 243 areas and analyzed by gamma spectrometry. The activity contents varied largely, ranging from 12.2 to 1,029 Bq k

6. Instituto de Radium de Minas Gerais: vanguarda da radioterapia no Brasil, 1923-1935
Este artigo propõe estudar os primeiros 12 anos de existência do Instituto de Radium de Minas Gerais, fundado em 1922. Sua atuação na luta contra o câncer no Brasil, ainda pouco conhecida, começa a ser esboçada pelo estudo de documentação institucional inédita. Através de um banco de dados elaborado com informações constantes em seu livro de reg

7. Submarine groundwater discharge revealed by radium isotopes (Ra-223 and Ra-224) near a paleochannel on the Southern Brazilian continental shelf
A descarga de água subterrânea ("Submarine Groundwater Discharge"; SGD) é um importante elo entre continente-oceano. No Brasil, embora haja um crescente interesse em estudos sobre este tema, eles ainda são raros e se restringem às zonas costeiras. A presente investigação explora as evidências SGD na Plataforma Continental do Sul do Brasil, as quais i

8. Investigation the natural radioactivity in local and imported chemical fertilizers
In order to assess the radioactive level in the environment, the specific activities of 238U, 232Th and 40K were measured by using a gamma ray spectrometer based on a NaI(Tl) detector. The results showed that the specific activities of 238U, 232Th and 40K were 12.846-88.585, 1.304-26.656 and 11.598-2275.896 Bq/kg respectively. The radium equivalent activity

9. Aspectos históricos da visita de Marie Sklodowska Curie a Belo Horizonte
In the year 2011 it is celebrated the Marie Sklodowska Curie Nobel Prize centenary and the International Year of Chemistry. However, it is not generally known that Marie Sklodowska Curie, one of the greatest scientists of all time, visited Belo Horizonte, state of Minas Gerais, Brazil. She arrived by train at Belo Horizonte city on 16 August 1926, coming fro

10. Levantamento dos níveis de radioatividade natural em águas do alto Vale do Ribeira à planície costeira do litoral sul do Estado de São Paulo / Assessment of natural radioctivity levels in waters from Higher Ribeira Valley until the southern Sao Paulo State coastal plain
The complex exchange of fluvial, subsurface and seawater within a coastal area directly affects global biogeochemical cycles and the application of isotopic tracers, mainly natural radionuclides from U and Th series, is a powerful tool to track sources and sinks of trace elements and nutrients to this systems. The unique Ra signature applied to quantify the

12. Avaliação radiométrica do U-238, Ra-226, Th-232 e K-40 em uma área anômala do agreste de Pernambuco
Estudos radiométricos e radioecológicos vêm sendo desenvolvidos mundialmente, em busca do mapeamento de áreas com elevados níveis de radioatividade, um pré-requisito essencial na investigação da exposição à radioatividade ambiental. Nesse trabalho foram estudadas amostras de rochas e solo derivado de uma área efetivamente anômala em urânio no m
