One‐Step Preparation of Lanthanide‐Doped Polyurea Multicolor Microspheres for Versatile Fluorescent Applications

open access: yesAdvanced Science, EarlyView.
Lanthanide‐doped polyurea microspheres are prepared via a facile one‐step precipitation polymerization. They exhibit strong hydrogen‐bonding and coordination interactions with excellent properties, including multicolor emission, high quantum yield (75.3%), remarkable stability, redispersibility, and biocompatibility.

Ultra‐Radiostable Covalent Conformationally Interlocked Networks Enabling a Universal Radiometal‐Labeling Platform for Cancer Radioembolization

open access: yesAdvanced Science, EarlyView.
Conjugated poly(imide dioxime)‐based microspheres establish a radiometal coordination‐driven conformational interlocked network with ultra‐high radiostability. This platform enables low‐temperature, multi‐radionuclide labeling for SPECT/PET/MRI imaging and radionuclide therapy. Mechanistic insights from EXAFS and DFT reveal enhanced stability, while in

Optimized Lipid Nanoparticles with Tail‐Modified Ionizable Lipids for Safer mRNA Delivery

open access: yesAdvanced Science, EarlyView.
Systematic engineering of hydrophobic tail architecture in vitamin B5‐derived ionizable lipids establishes a comprehensive structure–activity relationship framework for mRNA delivery. Combined lipidtail and formulation optimization identifies TM1‐OPT3‐C, a lipid nanoparticle platform that improves efficacy–safety balance through efficient mRNA delivery,

The Impact of Aging on the Anatomical Course of the Azygos Vein: A Retrospective, Computed Tomography Study

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The azygos vein (AV) is typically described as ascending vertically to the right of the vertebral column before arching anteriorly to drain into the superior vena cava. However, a small number of studies suggest that it is found leftward in older adults.

Transcatheter Closure of Persistent Left Superior Vena Cava Draining to Pulmonary Vein

open access: yesJACC: Case Reports, 2020
We describe a patient with recurrent embolic strokes who was found to have a persistent left superior vena cava draining into a pulmonary vein. Transcatheter placement of a vascular plug resulted in successful occlusion of the superior vena cava.

The Impact of a Visualized Steerable Sheath on Radiofrequency Catheter Ablation for First‐Time Atrial Fibrillation Ablation: A Prospective, Randomized, Single‐Blind Study

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background A 3D electroanatomical mapping (3D‐EAM) visualized steerable sheath was designed to improve catheter placement and reduce radiation exposure during ablation, an established treatment for atrial fibrillation (AF). However, prospective randomized data comparing the procedural and clinical outcomes of visualized and non‐visualized ...

MELD score predicts outcomes in patients with advanced heart failure: A longitudinal evaluation

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 839-847, April 2025.
Abstract Aims Advanced heart failure (AHF) is characterized by recurrent episodes of haemodynamic instability and frequent hospitalizations, leading to a progressive decline in quality of life and high mortality rates. The objectives of this study were to evaluate the effect of the model for end‐stage liver disease (MELD) score and its variations in ...

PERSISTENT LEFT SUPERIOR VENA CAVA: A DECEPTIVE ANOMALY

open access: yesJournal of Cancer and Allied Specialties, 2019
Persistent left superior vena cava (SVC) is a rare but vital congenital anomaly of the thoracic venous system. It is the persistence of vessel that normally regresses during early foetal life.

Implantable electrochemical sensors for continuous blood monitoring

open access: yesFlexMat, EarlyView.
Implantable electrochemical sensors enable direct, in situ, and continuous blood monitoring, shifting diagnosis from population‐based averages to dynamic, individualized analysis. This review systematically examines the influence of the unique blood properties on sensor design.
