Development and validation of an analytical method using High Performance Liquid Chromatography (HPLC) to determine ethyl butylacetylaminopropionate in topical repellent formulations

ABSTRACT Diseases caused by insects are frequent in poor countries, leading to epidemic scenarios in urban areas; e.g., Dengue, Zika and Chikungunya. For this reason, the development of a safe and efficient topical formulation is essential. Ethyl butylacetylaminopropionate (EB) is a mosquito repellent d...

Assessment of blood sample stability for complete blood count using the Sysmex XN-9000 and Mindray BC-6800 analyzers

Background: Different hematological analyzers have different analytical performances that are often reflected in the criteria for sample stability of the complete blood count. This study aimed to assess the stability of several hematological parameters using the XN-9000 Sysmex and BC-6800 Mindray analyze...

Detection of papillomavirus DNA in formalin-fixed paraffin-embedded equine aural plaque samples

A placa aural é uma dermatopatia associada à quatro Equus caballus papillomavirus (EcPVs). Até o momento, o DNA de EcPVs não foi identificado em amostras de placa aural fixadas em formalina e embebidas em parafina (FFPE). O objetivo deste estudo foi otimizar um método para a detecção dos quatro ti...
