2. The first survey of human T-cell lymphotropic viruses (HTLV) in HIV/AIDS patients in Santa Catarina State, Brazil
ABSTRACT Santa Catarina is a Brazilian State that has reported the lowest prevalence of human T-cell lymphotropic viruses (HTLV-1/2) in blood donors (0.04%). Although it presents ports, airports and roads that facilitate the entrance and dissemination of new infectious agents, no information exists concerning the HTLV-1/2 infections in HIV/AIDS patients. Thi

3. Oral lesions and retroviruses in shelter cats
RESUMO: As afecções orais são problemas comuns em medicina felina em diferentes locais do mundo e podem estar relacionadas a diferentes causas, como agentes infecciosos. Poucos estudos foram encontrados no Brasil sobre o levantamento das principais doenças orais e dos resultados de testes para retrovírus em gatos de abrigos, principalmente na região Su

4. HUMAN T-LYMPHOTROPIC VIRUS 1 (HTLV-1) AND HUMAN T-LYMPHOTROPIC VIRUS 2 (HTLV-2): GEOGRAPHICAL RESEARCH TRENDS AND COLLABORATION NETWORKS (1989-2012)
Publications are often used as a measure of research work success. Human T-lymphotropic virus (HTLV) type 1 and 2 are human retroviruses, which were discovered in the early 1980s, and it is estimated that 15-20 million people are infected worldwide. This article describes a bibliometric review and a coauthorship network analysis of literature on HTLV indexed

5. Characteristics of co-infections by HCV and HBV among Brazilian patients infected by HIV-1 and/or HTLV-1
BACKGROUND: The human retroviruses HIV-1 and HTLV-1 share the routes of infection with hepatitis viruses B and C. Co-infection by these agents are a common event, but we have scarce knowledge on co-infection by two or more of these agents. OBJECTIVE: To evaluate the characteristics and risk factors for co-infections by HBV and HCV in patients infected by HIV

6. Progress with schistosome transgenesis
Genome sequences for Schistosoma japonicum and Schistosoma mansoni are now available. The schistosome genome encodes ~13,000 protein encoding genes for which the function of only a minority is understood. There is a valuable role for transgenesis in functional genomic investigations of these new schistosome gene sequences. In gain-of-function approaches, tra

7. Avaliação do estresse oxidativo sob a resposta imune de bovinos infectados pelo vírus da leucose enzoótica bovina / Evaluation of oxidative stress on the immune response of bovine leukemia virus-infected dairy cows
Abundant observations of multiple pathogenic interactions between reactive oxygen species (ROS) and the pathogenesis of some retroviruses have drawn attention to role of ROS on disease progression and/or persistence of infection. Therefore, the role of the oxidative stress resulted from the modulation of the antioxidant system in dairy cows naturally infecte

8. The motor evoked potential in aids and HAM/TSP State of the evidence
OBJECTIVE: We aimed to better understand the involvement of the corticospinal tract, assessed by non-invasive transcranial stimulation, in order to determine the actual involvement of the motor system in patients with HAM/TSP and AIDS. METHOD: An exhaustive MEDLINE search for the period of 1985 to 2008 for all articles cross-referenced for "HTLV-I, HTLV-II,

9. Identification and detection of a novel human endogenous retrovirus-related gene, and structural characterization of its related elements
Up-regulation of human endogenous retroviruses (HERVs) is associated with many diseases, including cancer. In this study, an H family HERV (HERV-H)-related gene was identified and characterized. Its spliced transcript lacks protein-coding capacity and may belong to the emerging class of noncoding RNAs (ncRNAs). The 1.3-kb RNA consisting of four exons is tran

10. Diverse uses of feathers with emphasis on diagnosis of avian viral infections and vaccine virus monitoring
The large amounts of feathers produced by the poultry industry, that is considered as a waste was explored for possible uses in various industries, such as meals for animals, biofuels, biodegradable plastic materials, combating water pollution and more. That review mentions these uses, but concentrate on the utilization of feathers for the diagnosis of viral

11. Characterization and evolutionary dynamics of endogenous retroviruses K (ERV-K) in primate genomes. / Caracterização e dinâmica evolutiva de retrovírus endógenos da família K (ERV-K) em genomas de primatas.
Endogenous retroviruses (ERVs) are remains of ancient viral infection in the germ line cells and subsequent vertical transmission. The K family are integrated only in humans and the Old World monkeys. ERVs play a fundamental role on genome evolution and foster variability. The aim of this work was to investigate their distribution and evolutionary dynamics i

12. Hemotrophic mycoplasmas as potential cause of anemia in domestic cats / Micoplasmas hemotrópicos como potenciais agentes causadores de anemia em felinos domésticos
The present study aimed to evaluate the magnitude of the hemotrophic mycoplasmas infections in anemic cats. Samples from 270 anemic cats (PCV≤29%) and 53 healthy cats were submitted to hematological analysis (CBC, cytologic evaluation of blood smear), serum biochemistry (total protein, albumin, alkaline phosphatase, alanine aminotransferase, aspartate ami
