Safety assessment of Bong. Steud leaves extract: acute, sub-acute toxicity, antioxidant, and antihemolytic evaluations.

(Fabaceae), known popularly as pata-de-vaca and mororó has been largely recommended treating several diseases in folk medicine. However, information on safe doses and use is still scarce. The goal was to evaluate antioxidant and antihemolytic and also acute and sub-acute toxicity effects of hydroalcoholic extract from leaves (HaEBcl).

A 3D-printed robotic system for fully automated multiparameter analysis of drinkable water samples.

This work describes a 3D-printed robotic system named RSAWA (robotic system for automatic water analysis) for fully automated water analysis. RSAWA consists of a robotic arm coupled to a syringe pump, temperature and conductivity sensors, a low-cost webcam as colorimetric detector, and a 96-well microplate placed on a 3D-printed platform. The robotic system is controlled by software and it performs all analytical procedures.
