1. A cavidade bucal pode anunciar a presença de sarampo?
Sim, por volta do terceiro a quarto dia da febre, surgem na cavidade bucal inúmeras máculas branco-azuladas ou branco-acinzentadas, medindo de 1 a 3 mm, circundadas por um halo eritematoso, indolores, localizadas na mucosa jugal, próximo ao ducto de desembocadura das glândulas parótidas (ducto de Stenon). Estas máculas aumentam em número e coales

2. Plasmacytoid dendritic cells in dermatology,
Abstract Plasmacytoid dendritic cells are part of the dendritic cells family and are a relevant link between innate and adaptive immunity. They are the most potent producers of type 1 interferon, generating antiviral response, stimulating macrophages and dendritic cells and inducing activation and migration of natural killer cells. Plasmacytoid dendritic cel

3. Differential replicative fitness of the four dengue virus serotypes circulating in Colombia in human liver Huh7 cells
ABSTRACT Dengue has been a significant public health problem in Colombia since the simultaneous circulation of the four dengue virus serotypes. The replicative fitness of dengue is a biological feature important for virus evolution and contributes to elucidating the behavior of virus populations and viral pathogenesis. However, it has not yet been studied in

5. Mechanisms and biomarker candidates in pterygium development
RESUMO A patogênese do pterígio tem sido relacionada, prin cipalmente, à exposição à luz ultravioleta, mas esta asso ciação permanece bastante controversa. O mecanismo completo do pte rígio também permanece por esclarecer. Fatores como inflamação, infecção viral, estresse oxidativo, metilação do DNA, mediadores inflamatórios, moduladores de

6. Genetic and biological characterisation of Zika virus isolates from different Brazilian regions
BACKGROUND Zika virus (ZIKV) infections reported in recent epidemics have been linked to clinical complications that had never been associated with ZIKV before. Adaptive mutations could have contributed to the successful emergence of ZIKV as a global health threat to a nonimmune population. However, the causal relationships between the ZIKV genetic determi

7. Previous dengue or Zika virus exposure can drive to infection enhancement or neutralisation of other flaviviruses
BACKGROUND Dengue virus (DENV) has circulated in Brazil for over 30 years. During this time, one serotype has cyclically replaced the other, until recently, when all four distinct serotypes began to circulate together. Persistent circulation of DENV for long time periods makes sequential infections throughout a person’s life possible. After primary DENV

8. Consensus on the therapeutic management of atopic dermatitis - Brazilian Society of Dermatology
Abstract: BACKGROUND: Atopic dermatitis is a highly prevalent inflammatory and pruritic dermatosis with a multifactorial etiology, which includes skin barrier defects, immune dysfunction, and microbiome alterations. Atopic dermatitis is mediated by genetic, environmental, and psychological factors and requires therapeutic management that covers all the aspe

9. Regulation of HPV transcription
Human papillomavirus infection is associated with the development of malignant and benign neoplasms. Approximately 40 viral types can infect the anogenital mucosa and are categorized into high- and low-risk oncogenic human papillomavirus, depending on their association with the development of cervical carcinoma. High-risk human papillomavirus 16 and 18 are d

10. RNA viruses in trypanosomatid parasites: a historical overview
Viruses of trypanosomatids are now being extensively studied because of their diversity and the roles they play in flagellates’ biology. Among the most prominent examples are leishmaniaviruses implicated in pathogenesis of Leishmania parasites. Here, we present a historical overview of this field, starting with early reports of virus-like particles on elec

11. First detection of dengue virus in the saliva of immunocompetent murine model
The lack of an experimental animal model for the study of dengue pathogenesis is a limiting factor for the development of vaccines and drugs. In previous studies, our group demonstrated the susceptibility of BALB/c mice to infection by dengue virus (DENV) 1 and 2, and the virus was successfully isolated in several organs. In this study, BALB/c mice were expe

12. Zika puzzle in Brazil: peculiar conditions of viral introduction and dissemination - A Review
This article discusses the peculiar conditions that favoured the unexpected introduction of Zika virus into the poorest northeastern region of Brazil in 2015, its speed of transmission to other Brazilian states, other Latin American countries and other regions, and the severity of related neurological disorders in newborns and adults. Contrasting with eviden
