MEDI1814 selectively reduces free Aβ42 in cerebrospinal fluid of non-clinical species and Alzheimer's disease patients.

Introduction: Small molecules and antibodies are being developed to lower amyloid beta (Aβ) peptides.

Methods: We describe MEDI1814, a fully human high-affinity monoclonal antibody selective for Aβ, the pathogenic self-aggregating species of Aβ.

Results: MEDI1814 reduces free Aβ without impacting Aβ in the cerebrospinal fluid of rats and cynomolgus monkeys after systemic administration.

Introduction of a Novel Patient Safety Advisory: Evaluation of Perceived Information With a Modified QPP Questionnaire-A Case-Control Study.

Objectives: Adverse events (AEs) may result in serious injuries or death. AEs occur in approximately 9.2% of hospitalizations, with a potential preventability of 43.

Probing entanglement in a 2D hard-core Bose-Hubbard lattice.

Entanglement and its propagation are central to understanding many physical properties of quantum systems. Notably, within closed quantum many-body systems, entanglement is believed to yield emergent thermodynamic behaviour. However, a universal understanding remains challenging owing to the non-integrability and computational intractability of most large-scale quantum systems.

Fatal Intoxications with Zopiclone-A Cause for Concern?

Introduction: Zopiclone, a controlled substance prescribed for insomnia, has become a common toxicological finding in forensic autopsy cases. This study investigated the role and extent of zopiclone use in fatal intoxications in Sweden.

Methods: All forensic autopsy cases positive for zopiclone in femoral blood during 2012-2020 were selected.

Nicotinamide Prevents Retinal Vascular Dropout in a Rat Model of Ocular Hypertension and Supports Ocular Blood Supply in Glaucoma Patients.

Purpose: To investigate whether nicotinamide (NAM) modulates retinal vasculature in glaucoma.

Methods: This was a prospective controlled clinical trial investigating animal and human histopathology. Participants included normotensive and ocular hypertensive rats, postmortem human ocular tissue, glaucoma patients (n = 90), and healthy controls (n = 30).
