Dimorphic enantiostyly and its function for pollination by carpenter bees in a pollen‐rewarding Caribbean bloodwort

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Acute Exercise Challenge and Airway Dynamics in Youth With Sickle Cell Anemia: A Multicenter Study

open access: yesAmerican Journal of Hematology, EarlyView.
Changes in airway dynamics in children with sickle cell anemia after maximal cardiopulmonary exercise testing and a controlled intensity interval excercise challenge. ABSTRACT Sickle cell anemia (SCA) leads to reduced physical functioning and cardiopulmonary fitness. Prior studies suggest that airway hyperresponsiveness to bronchoprovocation testing is

Factor XIII Supplementation in Postpartum Hemorrhage: From Biological Rationale to Clinical Implementation

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Postpartum hemorrhage (PPH) remains the leading cause of preventable maternal mortality despite standard interventions. Recent fibrinogen trials failed to improve outcomes, prompting interest in coagulation factor XIII (FXIII). FXIII functions as “molecular cement,” cross‐linking fibrin and stabilizing clots.

Proteomic Analysis of Golden Sputum Reveals Pulmonary Complement Activation During Acute Chest Syndrome in Children With Sickle Cell Disease

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Acute chest syndrome (ACS) is one of the most common severe complications of sickle cell disease (SCD). In recent years, a major role of inflammation and innate immunity has been evidenced, but ACS pathophysiology remains incompletely understood, and therapeutic options are limited.
