Silaje de pasturas megatérmicas ¿es posible?

open access: yes, 2021
La conservación de forrajes para planteos ganaderos en forma de silaje es una práctica extendida desde la década del 90´. Entonces el disparador fue la irrupción de las tecnologías de embolsado, con maquinarias de alta capacidad de picado y de acomodo en las ahora comunes bolsas.

NRASQ61R mutation drives elevated angiopoietin‐2 expression in human endothelial cells and a genetic mouse model

open access: yesPediatric Blood &Cancer, Volume 71, Issue 7, July 2024.
Abstract Background Angiopoietin‐2 (Ang‐2) is increased in the blood of patients with kaposiform lymphangiomatosis (KLA) and kaposiform hemangioendothelioma (KHE). While the genetic causes of KHE are not clear, a somatic activating NRASQ61R mutation has been found in the lesions of KLA patients.
