Chapter 19: Vulnerability of coastal and estuarine habitats in the Great Barrier Reef to climate change [PDF]

, 2007
This chapter attempts to address the vulnerability of the CEM in the Great Barrier Reef region to global climate change. It does not consider individual habitats (eg reefs or seagrasses) but goes beyond the individual species and habitat assessments ...

A Biofabricated Human Acinus‐on‐a‐Chip Unveils Mechanotransductive Drivers of Ventilator‐Induced Lung Injury via Decoupling Volutrauma and Barotrauma

Advanced Science, EarlyView.
This bioinspired acinus‐on‐a‐chip recapitulates VILI pathology, revealing that volutrauma drives P53/NF‐κB pathways while barotrauma triggers mitochondrial‐Wnt dysregulation. A fibrotic transitional cell cluster was identified. Pharmacological interventions targeting these pathways significantly ameliorated injury, establishing a mechanobiological ...

Switching Spike Plasticity Shapes ACE2 Engagement Across SARS‐CoV‐2 Variants

Advanced Science, EarlyView.
Conformational plasticity governs SARS‐CoV‐2 spike function and ACE2 recognition. Using high‐speed AFM and single‐molecule force spectroscopy, we analyzed the ancestral spike and nine variants, revealing progressive rigidification from Delta, variable plasticity in Omicron sublineages, and JN.1 compaction.

Chapter 18: Vulnerability of pelagic systems of the Great Barrier Reef to climate change [PDF]

, 2007
This review focuses on pelagic environments. The oceanography of the Great Barrier Reef (GBR) is dynamic and is the physical template to which organisms respond. Planktonic assemblages are the basis of pelagic food chains and they provide a rich supply

Apexification of an Endodontically Failed Permanent Tooth with an Open Apex: A Case Report with Histologic Findings

Medicina
The management of an endodontic failure in a traumatized tooth with an open apex presents a major dilemma. The arrest of root growth after traumatic injury is a substantial consequence of pulpal necrosis. Conventional endodontic treatment procedures will
