The Power of Auxin in Plants [PDF]

open access: yesPlant Physiology, 2010
The existence of auxin as a mobile growth regulator was famously inferred by Charles and Frances Darwin, as described in their 1880 book, The Power of Movement in Plants ([Darwin and Darwin, 1880)][1]. However, auxin was not isolated until much later by [Went (1926)][2].

Sustained Therapeutic Efficacy of Intravenous Plasminogen Concentrate in Pediatric Patients With Type 1 Plasminogen Deficiency: An Analysis of Dosing Parameters and Clinical Outcomes

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Type 1 plasminogen deficiency (PLGD‐1) is an ultra‐rare autosomal recessive disorder caused by variants in the PLG gene and affects approximately 1.6 individuals per million. The condition is characterized by decreased plasminogen levels and impaired function, resulting in fibrin‐rich lesions on mucous membranes throughout the body.
