Cuantificación de los compuestos bioactivos y capacidad antioxidante del hongo Cordyceps sinensis para su uso potencial como aditivo alimentario

El uso de antioxidantes contribuye a disminuir el deterioro de los alimentos. Una práctica común en la actualidad es el uso de aditivos alimentarios de origen sintético, como el butilhidroxitolueno (BHT) y butilhidroxianisol (BHA). El hongo Cordyceps sinensis es ampliamente usado en la medicina asiát...

Poly(trimethylene carbonate-co-L-lactide) electrospun scaffolds for use as vascular grafts

Braz. j. med. biol. res; 52 (8), 2019
Currently, there is great clinical need for suitable synthetic grafts that can be used in vascular diseases. Synthetic grafts have been successfully used in medium and large arteries, however, their use in small diameter vessels is limited and presents a high failure rate. In this context, the aim of thi...
