Larvicidal Activity of Carbon Black against the Yellow Fever Mosquito .

The yellow fever mosquito is one of the deadliest animals on the planet because it transmits several medically important arboviruses, including Zika, chikungunya, dengue, and yellow fever. Carbon-based nanoparticles (CNPs) derived from natural sources have previously been shown to have toxic effects on mosquito larvae and offer a potential alternative to chemical insecticides such as pyrethroids, for which mosquitoes have evolved resistance. However, CNPs derived from industrial sources, such as carbon black, have not previously been evaluated as larvicides.

Silent ischemic events after Pipeline embolization device: a prospective evaluation with MR diffusion-weighted imaging.

Background: The development of ischemic events is relatively common after endovascular interventions, and flow diverters may pose a particular threat owing to their increased technical complexity and high metal content.

Objective: To investigate the incidence and potential risk factors for thromboembolic lesions after treatment with a Pipeline embolization device (PED).

Methods: This prospective study included a total of 59 patients electively treated with a PED over 12 months.
