Propolis is produced by honeybees and has many biological properties, including immunomodulatory, antiinflammatory, anti-oxidant, anti-bacterial, anti-viral and anti-cancer actions. Five ethanol extracts of Brazilian propolis were tested for inhibition of 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced inflammation in mice. The ethanol extract of Brazilian propolis AF-08 markedly inhibited T...

Recent studies have outlined the clinical and epidemiological profile of the spondyloarthritides in Ibero-American countries. The objective of this study was to compare the data collected in a Brazilian epidemiological study with the data obtained from other Ibero-American countries that used the same protocol of investigation. The Brazilian series presented a higher frequency of patients with ...

The enzyme profiles of three major Brazilian Trypanosoma cruzi zymodemes (Brazilian Z1, Brazilian Z2, Brazilian Z3) and of two principal Bolivian zymodemes were compared. Relationships were assessed both intuitively and by calculating genetic distances. One of the Bolivian zymodemes, Bolivian Z1, was closely related to the Brazilian Z1. The second Bolivian zymodeme, Bolivian Z2, was related to ...

INTRODUCTION The present study translated and adapted the Affective Norms for English Words (ANEW) to Brazilian Portuguese (ANEW-Br) and collected emotionality measures for a set of 1,046 words in Brazilian Portuguese. METHOD A sample of 755 male and female undergraduate students used the valence and arousal scales of the Self-Assessment Manikin to judge the emotionality of 1,046 words in Bra...

Standardized olfactory tests are now available to quantitatively assess disorders of olfaction. A Brazilian-Portuguese version of the University of Pennsylvania Smell Identification Test (UPSIT) is currently being developed specifically for the Brazilian population. The most recent Brazilian-Portuguese version of the UPSIT (UPSIT-Br2) was administered to 88 Brazilian subjects who had no history...

OBJECTIVE The aim of this study was to evaluate the psychometric properties of the Brazilian version of the Dental Fear Survey (DFS), previously translated to the Brazilian Portuguese language and validated. METHODS A cross-sectional study with 1,256 undergraduates from the city of Belo Horizonte, Brazil, was carried out. The DFS and a questionnaire about previous dental experiences were self...

OBJECTIVE To investigate whether Brazilian articles on cancer are published in journals with an impact factor and/or repercussion (measured by the number of citations) inferior to those that come from foreign organizations. METHODS A search was carried out in PubMed for the MeSH term "neoplasm" with the limits clinical trial, affiliation of the Brazilian author(s), and interval from July 1st,...

The Brazilian scientific production saw more than a four-fold increase from the 1990s onwards. The aim of this study was to evaluate the evolution of scientific production by Brazilian clinical neuroscientists over the last 10 years. A search in the PubMed identified 295 clinical neuroscientists and their publications. Brazilian production corresponded to 2.37% of the papers published by the 20...

BACKGROUND Brazilian propolis has many biological activities including the ability to help prevent thrombotic diseases, but this particular effect has not been proven. Plasma levels of plasminogen activator inhibitor-1 (PAI-1), an inhibitor of fibrinolysis, increase under inflammatory conditions such as infection, obesity and atherosclerosis and such elevated levels predispose individuals to a ...

Propolis contains a variety of bioactive components and possesses many biological properties. This study was designed to evaluate potential effects of Brazilian green propolis on glucose metabolism and antioxidant function in patients with type 2 diabetes mellitus (T2DM). In the 18-week randomized controlled study, enrolled patients with T2DM were randomly assigned to Brazilian green propolis g...
