2. Gestantes podem usar repelentes para mosquitos?
O uso de repelentes na gestação é seguro e está indicado como forma de proteção contra picadas de mosquitos, incluindo o Aedes aegypti, transmissor de doenças como dengue, chikungunya e zika Vírus.
O DEET (N-N-dietil-3-metil-toluamida) é a substância mais bem estudada e a mais fácil de ser encontrada no Brasil. Existem estudos em humanos,

3. Qual o repelente mais indicado para crianças de 6 meses a 2 anos?
Os repelentes indicados para crianças de 6 meses até 2 anos de idade são aqueles à base de IR3535.
Embora o FDA (Food and Drug Administration – EUA) indique evitarem-se repelentes apenas antes dos 2 meses, as recomendações oficiais da ANVISA (Agência Nacional de Vigilância Sanitária – Brasil) restringem o uso para crianças acima de 6 m

4. PREPARATION OF HYBRID POLYMERS AND USE AS CONTROLLED RELEASE DELIVERY VEHICLE FOR VOLATILE REPELLENT TO CONTROL Aedes aegypti
The Zika virus is a flavivirus spread by the Aedes aegypti mosquito, which also transmits dengue and chikungunya. Current forms of control include elimination of mosquito breeding sites, use of insecticides, repellents and other means. The present study developed new adsorbent materials based on silica and biomaterials capable of releasing an Aedes aegypti m

5. Inhibition of Brazilian ZIKV strain replication in primary human placental chorionic cells and cervical cells treated with nitazoxanide
ABSTRACT Zika virus (ZIKV) infection during pregnancy is associated with a congenital syndrome. Although the virus can be detected in human placental tissue and sexual transmission has been verified, it is not clear how the virus reaches the fetus. Despite the emerging severity caused by ZIKV infection, no specific prophylactic and/or therapeutic treatment i

6. Comparative bio-efficacy of nuclear polyhedrosis virus (NPV) and Spinosad against American bollwormm, Helicoverpa armigera (Hubner)
ABSTRACT American bollworm (ABW), Helicoverpa armigera (Hubner), is considered as a major pest of cotton, Gossypium hirsutum, all over the globe. Due to its destructive feeding nature and continuous consumption of the same chemicals, it devolved resistant against many insecticides. Therefore, a combined application of bio- and synthetic-pesticide need to eva

7. Moringa water extract promising additive to prolong the activity of baculovirus under field-sunlight conditions in Egypt
Resumo Os baculovírus são considerados como biopesticidas eficazes, exceto por não estarem ativos sob condições de luz solar. O objetivo deste estudo é avaliar a capacidade do extrato de moringa para prolongar a atividade do vírus sob condições de campo egípcias, tendo em vista que Moringa provou ser um material protetor forte sob investigação an

8. Identification of Zika virus in immature phases of Aedes aegypti and Aedes albopictus: a surveillance strategy for outbreak anticipation
A progressive increase in the circulation of arboviruses in tropical countries has been observed, accounting for 700,000 yearly deaths in the world. The main objective of this article was to identify the presence of Zika (ZIKV), dengue (DENV), and Chikungunya (CHIKV) viruses in immature stages of Aedes aegypti and Ae. albopictus. Household collections of imm

9. 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

10. Solubility as a limiting factor for expression of hepatitis A virus proteins in insect cell-baculovirus system
The use of recombinant proteins may represent an alternative model to inactivated vaccines against hepatitis A virus (HAV). The present study aimed to express the VP1 protein of HAV in baculovirus expression vector system (BEVS). The VP1 was expressed intracellularly with molecular mass of 35 kDa. The VP1 was detected both in the soluble fraction and in the

11. Interleukin-12 gene adjuvant increases the immunogenicity of virus-like particles of human papillomavirus type 16 regional variant strain
Objectives: To analyze the immunogenicity of virus-like particles (VLP) of human papillomavirus type 16 (HPV16) isolated in East China and the adjuvant potential of interleukin-12 (IL-12). Methods: The variant HPV16 L1VLP expressed in sf9 insect cells were purified with cesium chloride gradient centrifugation. BALB/c mice were vaccinated with VLP (L1N), V

12. Applications of molecular modeling in the design of new insect repellents targeting the odorant binding protein of Anopheles gambiae
Mosquitos são responsáveis pela transmissão de várias doenças causadas por vírus, parasitas e helmintos. Considerando o custo e a complexidade do tratamento dessas doenças, o uso de repelentes para proteção contra mosquitos vetores se torna uma alternativa interessante. Nesse contexto, no presente trabalho foram feitos estudos por ancoramento e din�
