Features of Brazilian spotted fever in two different endemic areas in Brazil

Ticks and Tick-borne Diseases, 2012
Brazilian spotted fever (BSF) caused by Rickettsia rickettsii is the most important rickettsiosis and the only reportable tick-borne disease in Brazil. In Brazil, the hard tick Amblyomma cajennense is the most important BSF vector; however, in São Paulo State, A. aureolatum was also recognized as a vector species in remaining Atlantic forest areas near

Serological Evidence of Human Coinfection by Brazilian Spotted Fever and Bartonellosis

International Journal of Clinical Medicine, 2016
Brazilian spotted fever and bartonellosis are zoonotic, emerging and under diagnosed diseases. Pets may be co-infected by multiple pathogens and become transmissions sources to humans. The study reports the first case of active co-infection by Brazilian spotted fever and bartonellosis based on serological evidence.

Inflammatory Response‐Inspired Thermochromic Shield for Pneumatic Structures

Advanced Engineering Materials, EarlyView.
A thermochromic shield for pneumatic structures is developed, using anhydrous sodium acetate powder and thermochromic pigment‐included solution. In this shield composed of three layers, the exothermic and thermochromic reactions, followed by the mixture of both components, occur promptly with an incident of penetrating damage as a sign of initial ...

Behavioral and epileptic phenotypes in a CHD2‐related developmental delay model

Epilepsia, EarlyView.
Abstract Objective Heterozygous loss‐of‐function mutations in the CHD2 gene, encoding chromodomain helicase DNA‐binding protein 2, are associated with severe childhood onset epilepsy, global developmental delay, and autistic features. Animal models that accurately recapitulate human phenotypes are crucial for understanding rare neurodevelopmental ...
