α-Amyrenone and β-amyrenone are triterpenoid isomers that occur naturally in very low concentrations in several oleoresins from Brazilian Amazon species of Protium (Burseraceae). This mixture can also be synthesized by oxidation of α,β-amyrins, obtained as major compounds from the same oleoresins. Using a very simple, high yield procedure, and using a readily commercially available mixture of α,β-amyrins as substrate, the binary compound α,β-amyrenone was synthesized and submitted to physico-chemical characterization using different techniques such as high-performance liquid chromatography, nuclear magnetic resonance (¹H and (13)C), mass spectrometry, scanning electron microscopy, differential scanning calorimetry, thermogravimetry and derivative thermogravimetry, and Fourier transform infrared spectroscopy (FTIR)...

The aim of this study was to analyze the repeatability in a stereophotogrammetry digital system used for the evaluation of facial morphology. Thirty healthy Brazilian, 18 to 45 years old (26.71 ± 6.53), had 11 reference landmarks marked on their faces by the same examiner and were photographed with an interval of 1 week by the VECTRA M3. Nine angular measurements (nasolabial, mentolabial, nasofrontal, maxillofacial, nasal, maxillary, mandibular, facial convexity, full facial convexity) and 2 linear measurements (middle facial height and lower facial height) were taken...

Brazilian philosopher-educator Paulo Freire defined critical consciousness as the ability to engage in reflection and action upon the world in order to transform it. A growing body of research has found that critical consciousness is predictive of a number of important academic and civic outcomes in adolescents from oppressed groups. The present mixed methods study considered the critical consciousness development of 335 adolescents (57% female, 92% African American or Latinx) attending urban secondary schools that sought to foster their students' critical consciousness, but featured five different pedagogical approaches...

Introduction and Objective: Dengue virus is a serious global health problem with an estimated 3.97 billion people at risk for infection worldwide. In December 2015, the first vaccine (CYD-TDV) for dengue prevention was approved in Brazil, developed by Sanofi Pasteur. However, given that the vaccine will potentially be paid via the public health system, information is need regarding consumers' willingness to pay for the dengue vaccine in the country as well as discussions related to the possible inclusion of this vaccine into the public health system...

Prorocentrum mexicanum and P. rhathymum are toxicologically important dinoflagellates, but their relationship is not well defined. We investigated strains from Puerto Rico and Brazil by light and scanning electron microscopies. We provide molecular data from a strain isolated near the type locality of P. rhathymum, and the first morphological and molecular data from the South Atlantic Ocean. The rRNA gene (rDNA) sequences of the Puerto Rican and Brazilian strains were identical, and their morphologies fit the description of P...

In 1958, the Pan American Health Organization declared that Brazil had successfully eradicated the mosquito Aedes aegypti, responsible for the transmission of yellow fever, dengue fever, chikungunya, and Zika virus. Yet in 2016 the Brazilian minister of health described the situation of dengue fever as "catastrophic." Discussing the recent epidemic of Zika virus, which amplified the crisis produced by the persistence of dengue fever, Brazil's president declared in January 2016 that "we are in the process of losing the war against the mosquito Aedes aegypti...

AIMS: This study validates the Portuguese version of the psychological effects of the relational job characteristics scale among hospital nurses in Portugal and Brazil. BACKGROUND: Increasing attention has been given to the social dimension of work, following the transition to a service economy. Nevertheless, and despite the unquestionable relational characteristics of nursing work, scarce research has been developed among nurses under a relational job design framework...

Central-line bloodstream infection (CLABSI) increases hospital mortality. A cohort study was conducted in a Brazilian hospital to estimate the disability-adjusted life year (DALY) of CLABSI using modified World Health Organization (WHO) methodology. CLABSI DALY was 20.44 per 1,000 inpatients, most were the result of premature death (20.42 per 1,000 inpatients). DALY can be useful to guide and measure the impact of healthcare infection prevention. Infect Control Hosp Epidemiol 2017;1-4.

Avian infectious bronchitis virus (IBV) primarily replicates in epithelial cells of the upper respiratory tract of chickens, inducing both morphological and immune modulatory changes. However, the association between the local immune responses induced by IBV and the mechanisms of pathogenesis has not yet been completely elucidated. This study compared the expression profile of genes related to immune responses in tracheal samples after challenge with two Brazilian field isolates (A and B) of IBV from the same genotype, associating these responses with viral replication and with pathological changes in trachea and kidney...

Estrogen is a steroidal hormone involved in several physiological functions in the female body including regulation of serum lipid metabolism and breast cancer (BC). Estrogen actions on serum lipids mostly occur through its binding to intracellular Estrogen Receptor alpha (ERalpha) isoform, expressed in most of tissues. This gene (ESR1) exhibit many polymorphic sites (SNPs) located either on translated and non-translated regions that regulate ERalpha protein expression and function. This paper aimed to investigate the association of two intronic SNPs of ESR1 gene, namely c454-397T>C (PvuII) and c454-351A>G (XbaI) to alterations in serum levels of total cholesterol (T-chol), total lipid (TL), low density lipoprotein cholesterol (LDL), high density lipoprotein (HDL), and triglycerides (TG) in a cohort of post-menopausal women...

INTRODUCTION: Prostate cancer still represents a major cause of morbidity, and still about 20% of men with the disease are diagnosed or will progress to the advanced stage without the possibility of curative treatment. Despite the recent advances in scientific and technological knowledge and the availability of new therapies, there is still considerable heterogeneity in the therapeutic approaches for metastatic prostate cancer. OBJECTIVES: This article presents a summary of the I Brazilian Consensus on Advanced Prostate Cancer, conducted by the Brazilian Society of Urology and Brazilian Society of Clinical Oncology...

Objective: to identify and analyse children's voices in healthcare decision making in the discourse of Brazil's child protection laws. Method: Documentary normative analysis of Brazil's child protection legislation (1988-2012) based on the content analysis of nine texts, conducted in 2015. Results: The legislation acknowledges and stresses the voice of children in the decision-making process in research and healthcare. Any recognition of the right to dignity, liberty, information, and protection depends on what the adult decision-maker (with parental authority) believes is the child's capacity for discernment and whether the situation will cause self-harm...

Priscila Bermudes Peixoto
This text results from research undertaken for a master's degree that focused on the proposed introduction of prenuptial medical exams in the early 1900s in Brazil. This was strongly defended by Brazilian eugenicists as a much-needed means of bringing about the racial improvement of the population. The exam would help prevent the marriage and reproduction of individuals considered degenerate or inferior, seen as inadequate for the eugenic development of future generations. The debate in Brazil between doctors and intellectuals who supported the introduction of a law that would make a prenuptial medical exam mandatory is analyzed, as are the controversies and objections voiced by its critics, ultimately helping ensure it was not adopted in the country...

This text analyzes the bill submitted by Alfredo Ellis Junior to the São Paulo legislature in August 1926, which would allow studies to be made of immigrants in São Paulo in order to orient immigration selection policies. It highlights the opinions of Menotti Del Picchia and Oliveira Vianna about the research agenda put forward by Alfredo Ellis Junior, focusing on the different conceptions about the race issue and immigration held in the 1920s. We suggest that Menotti Del Picchia's divergence from Alfredo Ellis Junior and Oliveira Vianna could be interpreted as a dispute between literati and scientists over the legitimacy of their respective knowledge about the Brazilian reality and the proposal of policies for the country...
