Leptospira kirschneri is one of the pathogenic species of the Leptospira genus. Human and animal infection from L. kirschneri gained further attention over the last few decades. Here we present the isolation and characterisation of Brazilian L. kirschneri serogroup Pomona serovar Mozdok strain M36/05 and the comparative genomic analysis with Brazilian human strain 61H. The M36/05 strain caused ...

Brazilian immigrants comprise the third largest ethnic group within the Japanese population. The aim of this cross-sectional study was to determine the factors associated with the prevalence of dental caries in Brazilian schoolchildren living in Japan. A total of 378 schoolchildren, aged between 6 and 14 years, attending Brazilian schools in Japan were included. Clinical data were collected acc...

The Brazilian Amazon Region is a highly endemic area for hepatitis B virus (HBV). However, little is known regarding the genetic variability of the strains circulating in this geographical region. Here, we describe the first full-length genomes of HBV isolated in the Brazilian Amazon Region; these genomes are also the first complete HBV subgenotype D3 genomes reported for Brazil. The genomes of...

14 editorial The Brazilian dental science " Men stand out for what they do; women, for what they induce men to do ". Three years ago, a sublime editorial 1 praised the audacious growth of Brazilian dental scientific production. At that time, our former editor dared to foresee the position Brazil would occupy in 2015: the most productive country in terms of dental scientific knowledge. The autho...

(Rock outcrop vegetation in Brazil: a brief overview). This paper overviews the special issue of the Brazilian Journal of Botany dedicated to “Rock outcrop vegetation in Brazil”. The main topics covered by this issue are phytogeography and vegetation ecology, plant life on shallow soils, plant reproduction and auto-ecology, morpho-physiology and plant adaptation, and finally conservation and gl...

Xeroderma pigmentosum (XP) is a rare autosomal recessive disorder characterized by DNA repair defects that cause photophobia, sunlight-induced cancers, and neurodegeneration. Prevalence of germline mutations in the nucleotide excision repair gene XPA vary significantly in different populations. No Brazilian patients have been reported to carry a germline mutation in this gene. In this study, th...

OBJECTIVE To test some psychometric properties of the Brazilian-Portuguese version of the Youth Quality of Life Instrument-Research (YQOL-R) in a community sample of Brazilian adolescents. METHODS This is a cross-sectional community study conducted in six schools of the catchment area of a family health unit. From an original population of 2,754 students from 10 to 17 years old, we randomly s...

OBJECTIVE The aim of this study was to identify the procedures adopted by Brazilian orthodontists in the following situations: extraction space closure, anchorage control in case of necessary anchorage for group A and frequency of skeletal anchorage use, especially in the upper jaw. METHODS A questionnaire was sent to the e-mail address of all dentists registered in the Brazilian Federal Coun...

This study aimed to evaluate in the Brazilian population, the genotypes and population frequencies of pharmacogenetic polymorphisms involved in the response to drugs used in treatment of acute lymphoblastic leukemia (ALL), and to compare the data with data from the HapMap populations. There was significant differentiation between most population pairs, but few associations between genetic ances...

This paper reports the annotation of a Brazilian Portuguese Treebank with semantic role labels following Propbank guidelines. A different language and a different parser output impact the task and require some decisions on how to annotate the corpus. Therefore, a new annotation guide – called Propbank-Br has been generated to deal with specific language phenomena and parser problems. In this ph...
