Chemotherapy-induced acute vascular injury involves intracellular generation of ROS via activation of the acid sphingomyelinase pathway
Several categories of chemotherapy confer substantial risk for late-term vascular morbidity and mortality. In the present study, we aimed to investigate the mechanism of acute chemotherapy-induced vascular injury in normal tissues. Specifically, we looked …

Motion-compensated noninvasive periodontal health monitoring using handheld and motor-based photoacoustic-ultrasound imaging systems
Simultaneous visualization of the teeth and periodontium is of significant clinical interest for image-based monitoring of periodontal health. We recently reported the application of a dual-modality photoacoustic-ultrasound (PA-US) imaging system for …

Accelerated atherosclerosis caused by serum amyloid A response in lungs of ApoE−/− mice
Airway exposure to eg particulate matter is associated with cardiovascular disease including atherosclerosis. Acute phase genes, especially Serum Amyloid A3 (Saa3), are highly expressed in the lung following pulmonary exposure to particles. We aimed to …

Selective cardiomyocyte oxidative stress leads to bystander senescence of cardiac stromal cells
Accumulation of senescent cells in tissues during normal or accelerated aging has been shown to be detrimental and to favor the outcomes of age-related diseases such as heart failure (HF). We have previously shown that oxidative stress dependent on …

Photoacoustic imaging of myocardial infarction region using non-invasive fibrin-targeted nanoparticles in a rat myocardial ischemia-reperfusion model
Background and Purpose: Myocardial infarction (MI) is a serious threat to public health. The early identification of MI is important to promote appropriate treatment strategies for patients. Recently, strategies targeting extracellular matrix (ECM) …

Xbp1s-FoxO1 axis governs lipid accumulation and contractile performance in heart failure with preserved ejection fraction
Heart failure with preserved ejection fraction (HFpEF) is now the dominant form of heart failure and one for which no efficacious therapies exist. Obesity and lipid mishandling greatly contribute to HFpEF. However, molecular mechanism(s) governing …

PH-triggered poly(ethylene glycol)-poly(lactic acid/glycolic acid)/ croconaine nanoparticles-assisted multiplexed photoacoustic imaging and enhanced photothermal cancer therapy
The most advantageous and attractive property of photoacoustic imaging is its capability to visualize and differentiate multiple species according to their unique absorbance profiles simultaneously in a single mixture. We here report the pH-sensitive …

Inhibition of NOX1 Mitigates Blood Pressure Increases in Elastin Insufficiency
Elastin (ELN) insufficiency leads to the cardiovascular hallmarks of the contiguous gene deletion disorder, Williams–Beuren syndrome, including hypertension and vascular stiffness. Previous studies showed that Williams–Beuren syndrome deletions, which …

Hollow Mesoporous Silica Nanoparticles Gated by Chitosan-Copper Sulfide Composites as Theranostic Agents for the Treatment of Breast Cancer
The combination of chemotherapy and photothermal therapy (PTT) into a single formulation has attracted increasing attention as a strategy for enhancing cancer treatment. Here, hollow mesoporous silica nanoparticles (HMSNs) were used as a base carrier …

Photoacoustic-guided surgery from head to toe [Invited]
Photoacoustic imaging-the combination of optics and acoustics to visualize differences in optical absorption-has recently demonstrated strong viability as a promising method to provide critical guidance of multiple surgeries and procedures. Benefits …
