Engineering a 3D Biomimetic Peptides Functionalized-Polyethylene Glycol Hydrogel Model Cocultured with Endothelial Cells and Astrocytes: Enhancing In Vitro Blood-Brain Barrier Biomimicry.

The blood-brain barrier (BBB) poses a significant challenge for drug delivery and is linked to various neurovascular disorders. In vitro BBB models provide a tool to investigate drug permeation across the BBB and the barrier's response to external injury events. Yet, existing models lack fidelity in replicating the BBB's complexity, hindering a comprehensive understanding of its functions.

Multicenter assessment of impairments and disabilities associated with Beirut blast injuries: a retrospective review of hospital medical records.

Objectives: This study aims to describe the injury patterns of the Beirut blast victims and assess hospitals' disaster management and preparedness during the 2020 Beirut port blast.

Methods: A cross-sectional retrospective multicenter study was conducted in two stages. Data were collected on blast victims presented to participating hospitals from August 4 till August 8, using three designed questionnaires.
