Time‐Controlled Dual Targeting to Program Systemic and Intercellular Transfer of Therapeutic Effects

open access: yesAdvanced Functional Materials, EarlyView.
Aspirin‐liposomes loaded onto monocytes enable inflammation‐triggered targeting and efficient hand‐over of aspirin to inflamed cells. Monocytes uptake a significant portion of aspirin‐liposomes, prolonging therapeutic action. This approach enhances anti‐inflammatory effects through intercellular transfer, demonstrating a translational strategy for ...

Non‐Enzymatic Destruction of the Extracellular Matrix for Activatable Orthotopic Tumor Treatment and Enhanced Drug Penetration

open access: yesAdvanced Functional Materials, EarlyView.
Supramolecular biomimetic nanoaggregates (HFCu NAs), constructed with fluorinated histidine and copper ions via metal coordination and aromatic packing, exhibit enhanced reactive oxygen species (ROS)generation at tumor sites, which results in stepwise collapse of the extracellular matrix (ECM), affording tumor microenvironment responsive “turn‐on” 19F ...

A Novel Approach For Finger Vein Verification Based on Self-Taught Learning [PDF]

open access: yesarXiv, 2015
In this paper, we propose a method for user Finger Vein Authentication (FVA) as a biometric system. Using the discriminative features for classifying theses finger veins is one of the main tips that make difference in related works, Thus we propose to learn a set of representative features, based on autoencoders.

Bioorthogonal Engineering of Cellular Microenvironments Using Isonitrile Ligations

open access: yesAdvanced Functional Materials, EarlyView.
Highly selective chemistries are required for fabrication and post‐cross–linking modification of cell‐encapsulating hydrogels used in tissue engineering applications. Isonitrile ligation reactions represent a promising class of bioorthogonal chemistries for engineering hydrogel‐based cellular microenvironments. Isonitrile‐based hydrogels are stable and

Hybrid endovascular and surgical staged approach for mycotic carotid pseudoaneurysms: a case report and literature review

open access: yesFrontiers in Surgery
BackgroundMycotic carotid pseudoaneurysms represent a challenge for surgeons. They are rare and associated with high mortality and morbidity.MethodsWe reported a case of a 61-year-old man with a mycotic pseudoaneurysm of carotid bifurcation. The case was

PVTree: Realistic and Controllable Palm Vein Generation for Recognition Tasks [PDF]

open access: yesarXiv
Palm vein recognition is an emerging biometric technology that offers enhanced security and privacy. However, acquiring sufficient palm vein data for training deep learning-based recognition models is challenging due to the high costs of data collection and privacy protection constraints.
