We disclose a novel strategy to design n-type acenes through the introduction of boron-nitrogen coordination bonds (B←N). We synthesized two azaacenes composed of two B←N units and six/eight linearly annelated rings. The B←N unit significantly perturbed the electronic structures of the azaacenes: Unique LUMOs delocalized over the entire acene skeletons and decreased aromaticity of the B←N-adjacent rings. Most importantly, these B←N-containing azaacenes exhibited low-lying LUMO energy levels and high electron affinities, thus leading to n-type character. The solution-processed organic field-effect transistor based on one such azaacene exhibited unipolar n-type characteristics with an electron mobility of 0.21 cm V s .

Introduction: This prospective, single-arm pharmacodynamic study assessed the effect of colchicine (COLC) [Strides Pharma UK Ltd, Watford, Hertfordshire, England] 0.5 mg administered orally once daily for 14 days on platelet reactivity with respect to aspirin reaction units (ARUs) and P2Y reaction units (PRUs).
Methods: Twenty-two patients with stable coronary artery disease (CAD) on dual antiplatelet therapy (DAPT) with daily maintenance aspirin and clopidogrel were recruited.

Introduction: Anticoagulant therapy is critical for venous thromboembolism (VTE) management, though bleeding remains a major concern, ranging from mild to fatal events. This study aimed to assess the predictive value of cytokines for major bleeding in patients with acute pulmonary embolism (PE).
Methods: In this prospective, observational study, patients aged ≥ 18 years with acute PE were enrolled from April 2021 to September 2022 and followed for 30 days.

Purpose: To assess the level of moral distress (MD) and perceptions of ethical climate among pediatric hematology/oncology (PHO) nurses and to identify bioethics topics where increased education was desired.
Methods: In this cross-sectional study, we administered the 26-item Swedish Moral Distress Scale-Revised (sMDS-R), specifically revised and validated for pediatric oncology, in conjunction with the Clinical Ethics Needs Assessment Survey (CENAS). Electronic surveys were sent to inpatient and outpatient PHO nurses.
