Marine protected areas (MPAs) are widely used to conserve and manage coastal resources. Protected areas are governed by a variety of institutional arrangements, yet little is known concerning the relative performance of different governance approaches. This research draws upon a unique dataset that combines details on the reported International Union for Conservation of Nature (IUCN) governance categories of 217 global MPAs and their ecological outcomes to compare the performance of alternative governance arrangements.

Clinical trial design for classical hematologic diseases is difficult because samples sizes are often small and not representative of the disease population. ASH initiated a Roadmap project to identify barriers and make progress to integrate diversity, equity, and inclusion into trial design and conduct. Focus groups of international experts from across the clinical trial ecosystem were conducted.

Background: Tissue factor (TF) pathway inhibitor (TFPI) is an anticoagulant protein that inhibits factor (F)Xa, the TF-FVIIa-FXa complex, and early forms of the prothrombinase complex. Concizumab is a monoclonal antibody that blocks FXa inhibition by TFPI and reduces bleeding in hemophilia.

Objectives: To examine how concizumab impacts various reactions of TFPI to restore thrombin generation in hemophilia A using mathematical models.

Article Synopsis
  • - Platelet factor XIII-A (FXIII-A) is a significant protein in platelets, with over 80% remaining attached to platelets even after strong activation, while other proteins like tissue factor pathway inhibitor are released.
  • - The retention of FXIII-A during platelet activation is influenced by various factors including STIM1 signaling, microtubule changes, calpain activity, and RhoA activation, but it does not rely on the presence of fibrinogen or plasminogen.
  • - Despite being released, the FXIII-A found in the supernatant is cleaved and susceptible to degradation, whereas the FXIII-A remaining with the platelets is intact, indicating distinct biological roles for platelet-derived and plasma

Purpose: Childhood cancer survivors carry a high burden of late-occurring treatment-related morbidity. Long-term risk-based anticipatory surveillance allows for early detection and management of complications. We sought to examine demographic, clinical, and social characteristics associated with survivorship clinic attendance at the Taking on Life after Cancer (TLC) Clinic at the Children's Hospital of Alabama.
