Pulmonary venous abnormalities encountered on pre-radiofrequency ablation mapping multidetector computed tomography

open access: yesSouth African Journal of Radiology, 2017
Multidetector computed tomography (MDCT) elegantly renders pulmonary venous anatomy. With increasing numbers of radiofrequency ablation procedures being performed, there is now a greater emphasis on pre-procedure imaging to delineate this anatomy ...

Upregulation of ET-1 and its receptors and remodeling in small pulmonary veins under hypoxic conditions

open access: yes, 2001
Pulmonary veins show greater sensitivity to endothelin (ET)-1-induced vasoconstriction than pulmonary arteries, and remodeling was observed in pulmonary veins under hypoxic conditions.

Plaque‐Hepatic Targeting Nanotherapy Disrupts the PCSK9‐LOX‐1 Axis to Suppress oxLDL in Atherosclerosis

open access: yesAdvanced Science, EarlyView.
Self‑amplifying PCSK9–LOX‑1 feedback axis drives atherosclerotic progression by promoting oxLDL generation and endothelial uptake. A dual‑targeting nanoplatform (siPCSK9@PEAL NPs‑aL) is constructed to simultaneously silence hepatic PCSK9 for lipid lowering and block plaque LOX‑1 for anti‑inflammation.

Comment to: Acute and chronic consequences of polidocanol foam injection in the lung in experimental animals by Grandi L, Grandi RA, Tomasi CD, da Rocha JL, Cardoso V, Dal-Pizzol F. Phlebology 2013;28:441-4.

open access: yesVeins and Lymphatics, 2014
To assess the occurrence of pulmonary embolism and long-term inflammatory activation after polidocanol foam injection, domestic rabbits, of both sexes, weighing around 2 kg were used: a control group (injection of saline solution, n = 4) and an ...

Isolated right pulmonary artery discontinuity [PDF]

open access: yes, 2000
Unilateral “absence” of the pulmonary artery is an uncommon malformation frequently associated with congenital heart disease. In fact, the pulmonary artery is typically discontinuous from the main pulmonary artery, not absent.

Versatile Co‐Engineering of Immunogenic Cell Death‐Primed Dead Tumor Cell Bodies With Tumor‐Activated MnO2 for cGAS‐STING‐Potentiated Personalized Immunotherapy

open access: yesAdvanced Science, EarlyView.
DTBEI@CS@MnO2, fabricated via modular electrostatic co‐engineering and photothermal/photodynamic immunogenic cell death, specifically responds to the acidic and GSH‐rich tumor microenvironment. This triggers the release of DTBEI that provides tumor antigens, DNA, and DAMPs, as well as the generation of Mn2+, thereby synergistically potentiating cGAS ...

Recapitulating In Vivo Pharmacokinetics and Size‐Dependent Nanomedicine Delivery in a Microfluidic Platform

open access: yesAdvanced Science, EarlyView.
A microfluidic tumor platform integrates pharmacokinetic flow control, vascular‐like barriers, and 3D tumor spheroids to emulate in vivo drug exposure. The system reproduces dynamic concentration–time profiles and enables size‐dependent nanoparticle transport and efficacy evaluation, providing a predictive framework for assessing nanomedicine ...

Iron‐Tannic Acid Hydrogel Mediated Mild Photothermal Therapy Combined With Ferroptosis Enhances Anti‐Tumor Immunity in Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
An injectable gelatin‐based tannic acid–iron hydrogel with mild photothermal therapy could not only induce immunogenic cell death, but also elicit ferroptosis of both tumor cells and tumor‐associated macrophages, resulting in DC maturation, T‐cell infiltration and down‐regulation of ferroptosis‐sensitive M2‐type TAMs levels.

Dual‐Targeting Biomimetic Nanozymes Loaded Microneedle Patch Promotes Scarless Wound Healing Through Anti‐Inflammatory and Anti‐Fibrotic Effects

open access: yesAdvanced Science, EarlyView.
This study developed a dual‐targeting biomimetic nanozyme hybrid system (Cu‐CeO2@ABs‐FTP) and integrated it with HAMA hydrogel to fabricate a microneedle patch (CAF@MN). The patch promotes fibroblast‐mediated wound repair, targets macrophages to induce M2 polarization, and targets myofibroblasts to exert anti‐fibrotic effects, thereby enabling rapid ...

Defect‐Engineered BiO2‐X Nanosheets Mediate Sono‐Thermomechanical ECM Remodeling for Hepatocellular Carcinoma Immunotherapy

open access: yesAdvanced Science, EarlyView.
Herein, an ultrasound‐responsive BiO2‐X/siFn1 nanoplatform is developed to overcome anti‐PD‐1 resistance in hepatocellular carcinoma. Upon ultrasound irradiation, the platform downregulates fibronectin expression, while its sonothermal effect softens the dense extracellular matrix and activates antitumor immunity in the tumor microenvironment, thereby ...
