Tailoring the Properties of Functional Materials With N‐Oxides

open access: yesAdvanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.

Optimization of the Nonclinical Biological Evaluation of Medical Devices Using Toxicologic Pathology Best Practices

open access: yesAdvanced Healthcare Materials, EarlyView.
Nonclinical evaluation of biological responses to implanted medical devices and combination products in animals is required to predict possible outcomes and risks in patients. This paper describes globally accepted pathology “best practices” that 1) effectively address ISO standards and current regulatory guidance for medical device development and 2 ...

Myeloperoxidase Luminol Reaction – A Novel Faecal Assay for Predicting Colonoscopy Findings in Patients with Ulcerative Colitis: A Pilot Cross‐Sectional Clinical Study

open access: yesAdvanced Healthcare Materials, EarlyView.
Can luminol detect faecal inflammation? This study explores the development and optimisation of a rapid novel assay ‐ Myeloperoxidase Luminol Reaction (MPOLR) for the detection of faecal myeloperoxidase activity. This simple and rapid luminol‐based approach competes with clinically validated faecal biomarkers in predicting endoscopic findings in ...

Mesoporous Bioactive Glasses: A Powerful Tool in Tissue Engineering and Drug Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
This work is a comprehensive revision of bioactive glasses (BGs), pioneered by Prof. L.L. Hench, which are key in bone repair and regenerative medicine. Sol–gel methods and mesoporous designs enhanced their bioactivity, ions, and drug delivery. BGs now support gene therapy and 3D‐printed scaffolds, enabling personalized, multifunctional treatments in ...

Colonic Dieulafoy's Lesion: A Rare Cause of Lower Gastrointestinal Hemorrhage and Review of Endoscopic Management

open access: yesCase Reports in Gastrointestinal Medicine, 2014
Dieulafoy's lesions are a rare cause of gastrointestinal hemorrhage. Extragastric Dieulafoy's lesions are even more uncommon. We report the case of a 75-year-old woman who presented with gastrointestinal bleeding from a transverse colonic Dieulafoy's ...

Gastrointestinal Hemorrhage in Warfarin Anticoagulated Patients: Incidence, Risk Factor, Management, and Outcome

open access: yesBioMed Research International, 2014
Background. Warfarin reduces the incidence of thromboembolism but increases the risk of gastrointestinal bleeding (GIB). GIB during warfarin anticoagulation is rarely evaluated in Asian patients. Aims.

New Insights into Atonic Postpartum Hemorrhage: Animal Model Construction Based on Placental Nanodelivery Systems

open access: yesAdvanced Healthcare Materials, EarlyView.
This study develops a placenta‐targeted nanodelivery system co‐loading HMGB1 protein and the NLRP3 agonist nigericin to establish an animal model of atonic postpartum hemorrhage. The model accurately recapitulates clinical phenotypes, including prolonged labor and uterine contractility dysfunction, while revealing inflammatory activation in placental ...
