This article proposes to study the first 12 years of the Minas Gerais Radium Institute, founded in 1922. Its work in the fight against cancer in Brazil, albeit still little known, is coming to light as its institutional documents are studied. A database has been prepared using information from its patient register, based on which statistical analyses have been done to identify the types of canc...

We evaluated the antimicrobial activities of a cationic Gemini surfactant, trans-1,4-bis[2-(alkanoyloxy)ethyldimethylammonio]-2-butene dichloride [II-m-2(t-butene)] and its derivatives against Gram-positive and Gram-negative microorganisms. The II-m-2(t-butene) compound was previously shown to have good surface activity and biodegradability. A dodecanoyloxy derivative (m = 12) of II-m-2(t-buten...

Radium ((226)Ra) contamination derived from military, industrial, and pharmaceutical products can be found at a number of historical sites across the world posing a risk to human health. The analysis of spectral data derived using gamma-ray spectrometry can offer a powerful tool to rapidly estimate and map the activity, depth, and lateral distribution of (226)Ra contamination covering an extens...

Introduction: Among High Level Natural Radiation Areas (HLNRAs) all over the world, the northern coastal city of Ramsar has been considered enormously important. People living in this area have been exposed by several sources, one of which could be foodstuff. However, many studies have been carried out to measure the environmental radioactivity in Ramsar, but no survey has been...

INTRODUCTION Carotid endarterectomy may be performed under general (GA) or regional anesthesia (RA). The aim of this study was to evaluate the influence of anesthetic techniques on perioperative mortality and morbidity in patients undergoing carotid surgery. MATERIAL AND METHODS This prospective study included 1098 consecutive patients operated on between 2003 and 2009 (773 underwent cervical...

Over the last decades, there has been a plethora of interest in possible challenges encountered by researchers while publishing research articles (RAs) in various disciplines for English for academic purposes (EAP).Given this, this study aimed to examine how a sampled number of EAPIranian researchers perceive the competence of academic RA writing, the major reasons for RA rejection, and difficu...

The development of automated methods for revealing the repetitive structure of a given music recording is of central importance in music information retrieval. In this paper, we present a novel scape plot representation that allows for visualizing repetitive structures of the entire music recording in a hierarchical, compact, and intuitive way. In a scape plot, each point corresponds to an audi...
