1. Genética das demências: percepção a partir da América Latina
RESUMO. A doença de Alzheimer (DA) e a demência frontotemporal (DFT) são distúrbios neurodegenerativos que causam uma sobrecarga significativa para pacientes e cuidadores. Em 2050, o número de pessoas com demência na América Latina aumentará 4 vezes. Uma compreensão profunda dos fatores genéticos relevantes da DA e da DFT é fundamental para enfren

2. Microbial Profile of Supragingival and Subgingival Plaque of Patients With Glycogen Storage Disease
Abstract Patients with glycogen storage disease (GSD) are either orally fed (ORF) or gastronomy-tube fed (GTF) with cornstarch to maintain normal glucose levels. It is not known whether the use of cornstarch affects the microbiological oral profile of patients with GSD. Thus, the purpose of this study was to compare supragingival and subgingival plaque sampl

3. Detection and genetic characterization of Mamastrovirus 5 from Brazilian dogs
Abstract Mamastrovirus 5 (MAstV5), belonging to the Astroviridae (AstV) family, previously known as canine astrovirus or astrovirus-like particles, has been reported in several countries to be associated with viral enteric disease in dogs since the 1980s. Astroviruses have been detected in fecal samples from a wide variety of mammals and birds that are assoc

4. Structure analysis of capsid protein of Porcine circovirus type 2 from pigs with systemic disease
Abstract Economic losses with high mortality rate associated with Porcine circovirus type 2 (PCV2) is reported worldwide. PCV2 commercial vaccine was introduced in 2006 in U.S. and in 2008 in Brazil. Although PCV2 vaccines have been widely used, cases of PCV2 systemic disease have been reported in the last years. Eleven nursery or fattening pigs suffering fr

5. High frequency of hepatitis E virus infection in swine from South Brazil and close similarity to human HEV isolates
Abstract Hepatitis E virus is responsible for acute and chronic liver infections worldwide. Swine hepatitis E virus has been isolated in Brazil, and a probable zoonotic transmission has been described, although data are still scarce. The aim of this study was to investigate the frequency of hepatitis E virus infection in pigs from a small-scale farm in the r

6. Calcium homeostasis modulator 1 ( CALHM1 ) polymorphisms in cattle
ABSTRACT: The calcium homeostasis modulator 1 gene (CALHM1), which is located on chromosome 10 in humans and on chromosome 26 in cattle, is a transmembrane glycoprotein that controls the cytosolic calcium concentrations. Altered calcium homeostasis has been associated with several neurodegenerative disorders, including Alzheimer’s disease (AD). In a recent

7. Malignant Catarrhal Fever in Brazilian cattle presenting with neurological syndrome
Abstract Malignant Catarrhal Fever (MCF) was investigated in the central nervous system of cattle with neurological syndrome. Two-hundred-ninety samples were analyzed by histology, and molecular methods to detect ovine herpesvirus type 2 (OvHV-2) were optimized and validated. The qualitative polymerase chain reaction (qualitative PCR) analytical sensitivity

8. Mapping and allelic sequencing of a long sterile lemma trait in rice
ABSTRACT Some outer floral organs are unique in gramineous plants, like the sterile lemma and rudimentary glume in rice. However, their development mechanisms are still poorly understood. In this study, we used 4 mutants with long sterile lemma (LSL), named JF11, JF12, JF13 and JNY-7, to be crossed with Aijiaonante (AJNT) and Nipponbare (NIP), respectively.

9. In Silico Identification of MicroRNAs with B/CYDV Gene Silencing Potential
ABSTRACT Computational investigation of a set of publicly available plant microRNAs revealed 19 barley- and other plants-encoded miRNAs and their near-complement reverse sequences (miRNA*) that have potential to bind all B/CYDV open reading frames (ORFs) except ORF0 and ORF6. These miRNAs/miRNAs*, their binding positions and targets are discussed in the cont

10. Associação da ocorrência do ectima contagioso (ORF vírus) em ovinos com os cuidadores desses animais
RESUMO A enfermidade ectima contagioso está difundida em todo o estado de São Paulo. Foram amostrados 42 (8,64%) cuidadores de animais e 444 (91,36%) ovinos (n=486). A prevalência de reagentes para vírus-neutralização foi de 67% (IC95%=62-71%) nos ovinos, e em seus cuidadores de 76% (IC95%=63-89%), sendo P=0,22, ou seja, não houve diferença estatíst

11. Hepatitis E virus seroprevalence among schistosomiasis patients in Northeastern Brazil
Abstract Background Hepatitis E virus (HEV) can cause chronic infection with rapid progression to liver cirrhosis in immunocompromised patients. HEV seroprevalence in patients with Schistosoma mansoni in Brazil is unknown. We evaluated the prevalence of past or present HEV infection in schistosomiasis patients in Recife, Pernambuco, Brazil. A total of 80 pa
