Floppy epiglottis together with extra-laryngeal mass causing an inducible laryngeal obstruction and hypoxemic event in an adult: A case report

Saudi Journal of Anaesthesia, 2020
Floppy epiglottis in an adult is rare and often pathological. Airway obstruction caused by floppy epiglottis in an adult is rarely reported. Neck mass, however, can affect the airway in many ways; however, inducible upper airway obstruction by extra ...

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 ...

Targeting the NR1D1–IGF2BP2–V‐ATPase Axis With Hybrid Nanovesicles Restores Macrophage Rhythms to Reverse Sepsis‐Induced Immunosuppression

Advanced Science, EarlyView.
Sepsis disrupts immune‐cell rhythms and weakens bacterial clearance. Biomimetic nanovesicles combining erythrocyte and inflammation‐activated macrophage membranes deliver siNR1D1 to dysfunctional macrophages, restoring the NR1D1–IGF2BP2–V‐ATPase pathway, circadian regulation, phagolysosomal acidification, and antimicrobial defense.

Bone Marrow Macrophage STING Signaling is a Direct Nexus Linking Marrow Adipose Expansion to NAD+ Depletion and Osteogenic Decline in Skeletal Aging

Advanced Science, EarlyView.
This study reveals that during skeletal aging, bone marrow adipocyte‐derived sDPP4 primes STING signaling in macrophages. In combination with mitochondrial DNA, this signaling activates CD38 and depletes local NAD+/NMN, thereby impairing osteogenesis.

Multilevel airway obstruction including rare tongue base mass presenting as severe croup in an infant [PDF]

, 2013
Laryngomalacia is the most common cause of neonatal stridor, accounting for up to 60% of cases. Less common causes of neonatal stridor include subglottic or tracheal stenosis, or congenital masses of the upper airway.

Mapping Embryonic Mouse Lung Development Using Enhanced Spatial Transcriptomics

Advanced Science, EarlyView.
The mammalian lung contains ∼50 cell types arranged along the airway epithelium. Here, deterministic barcoding sequencing (DBiT‐seq) is optimized to nearly double transcript recovery, enabling highly sensitive spatial mapping of the embryonic mouse lung.
