Temperature‐Dependent Zinc Oxide Cathodoluminescence: Toward Compact Wavelength‐Tunable Solid‐State Photoionization Sources

Advanced Optical Materials, EarlyView.
A proof‐of‐concept of a thermally‐tunable cathodoluminescence‐based light source is demonstrated using a wide‐bandgap z‐cut ZnO crystal as anode, resulting in the ultraviolet (UV) emission peak shifting from 398 nm to ~409 nm (3.115‐3.032 eV). Our results establish the feasibility of a compact, field‐deployable UV source with potential for gas sensing ...

CD207‐Positive Dendritic Cells Promote Emphysema Through CD8+ T Cell Pathway in Chronic Obstructive Pulmonary Disease

Advanced Science, EarlyView.
CD207+ dendritic cells (DCs) drive emphysema by promoting CD8⁺ T cell cytotoxicity via Birbeck granule‐dependent MHC‐I antigen presentation. This DC subset is expanded by cigarette smoke‐induced oxidative stress, which triggers granulocyte‐macrophage colony‐stimulating factor (GM‐CSF) release from airway epithelium.

Impact of atrial fibrillation on the cardiovascular system through a lumped-parameter approach [PDF]

, 2014
Atrial fibrillation (AF) is the most common arrhythmia affecting millions of people in the Western countries and, due to the widespread impact on the population and its medical relevance, is largely investigated in both clinical and bioengineering ...

Indole‐3‐Propionic Acid Improves Alveolar Development Impairment via Targeting VAMP8‐mediated SNAREs Complex Formation in Bronchopulmonary Dysplasia

Advanced Science, EarlyView.
This study aims to evaluate the impact of the tryptophan‐derived metabolite indole‐3‐propionic acid (IPA) on lung development and autophagic flux. IPA alleviates hyperoxia‐induced alveolar arrest by promoting autophagosome‐lysosome fusion via inhibition of VAMP8 phosphorylation, which is suggestive of a promising therapeutic target of BPD.

Pulmonary Artery Wedge Pressure Lability in the Bovine

Experimental Biology and Medicine, 1972
SummaryIn 10 normal calves and 7 calves with brisket disease, injections of small volumes of normal saline into the wedged pulmonary artery catheter were shown to produce transient but significant increases in pulmonary-artery wedge pressure that could be reversed with isoproterenol.

Association of PET-measured myocardial flow reserve with echocardiography-estimated pulmonary artery systolic pressure in patients with hypertrophic cardiomyopathy [PDF]

, 2019
BackgroundPulmonary hypertension (PH) is a known complication of HCM and is a strong predictor of mortality. We aim to investigate the relationship between microvascular dysfunction measured by quantitative PET and PH in HCM patients.MethodsEighty-nine ...

Rupestonic Acid of Artemisia Rupestris L. Extract Treats Pulmonary Fibrosis in COPD by Targeting TGF‐β1

Advanced Science, EarlyView.
RA of EEAR inhibits TGF‐β1 ubiquitination and changes conformation by target binding TGF‐β1, regulating TGF‐β1/Smad2/3 signaling pathway. Thus it down‐regulated downstream protein expression, inhibited EMT and collagen deposition of ECM, in order to EEAR preventing PF in COPD.

Absence of reflex vascular responses from the intrapulmonary circulation in anaesthetised dogs [PDF]

, 2000
The aim of this investigation was to determine whether reflex cardiovascular responses were obtained to localised distension of the intrapulmonary arterial and venous circulations in a preparation in which the stimuli to other major reflexogenic areas ...

Inactivation of AXL in Cardiac Fibroblasts Alleviates Right Ventricular Remodeling in Pulmonary Hypertension

Advanced Science, EarlyView.
Pulmonary hypertension (PH) is a progressive condition with high morbidity and mortality, largely owing to right ventricular (RV) failure resulting from maladaptive remodeling. Our study provides strong evidence in support of a critical, detrimental role for AXL as a previously unrecognized determinant driving RV fibrotic pathology in PH.
