Nuclear medicine imaging has been developed as a powerful diagnostic approach for cancers by detecting gamma rays directly or indirectly from radionuclides to construct images with beneficial characteristics of high sensitivity, infinite penetration depth and quantitative capability. Current nuclear medicine imaging modalities mainly include single...

Following myocardial infarction (MI), necrotic cardiomyocytes (CMs) are replaced by fibroblasts and collagen tissue, causing abnormal electrical signal propagation, desynchronizing cardiac contraction, resulting in cardiac arrhythmia. In this work, a conductive polymer, poly-3-amino-4-methoxybenzoic acid (PAMB), is synthesized and grafted onto non-...

In regards to their key role in intercellular communication, extracellular vesicles (EVs) have a strong potential as bio-inspired drug delivery systems (DDS). With the aim of circumventing some of their well-known issues (production yield, drug loading yield, pharmacokinetics), we specifically focused on switching the biological vision of these ent...

Constructing a small-diameter artificial blood vessel with biological functions and mechanical compliance comparable to native tissues is still a major challenge in vascular tissue engineering. To address the issues of severe thrombosis and unsatisfactory long-term patency in small-diameter vascular grafts, herein we designed a specifically biomime...

Background: The results of studies examining the response to experimental pain during the menstrual cycle are conflicting because of differences in the definitions of the menstrual period, outcome measures and types of experimental pain stimulation. So far, there have been only a few studies correlating experimental pain with the levels of gonadal ...

Exposure of cells to externally applied magnetic fields or to scaffolding materials with intrinsic magnetic properties (magnetic actuation) can regulate several biological responses. Here, we generated novel magnetized nanocomposite hydrogels by incorporation of magnetic nanoparticles (MNPs) into polyethylene glycol (PEG)-based hydrogels containing...

Selenoxide elimination reaction has been widely used in the field of organic synthesis. However, few studies have been conducted to apply this reaction in biodegradable nanomedicine. In this work, the selenoxide elimination reaction was used for cancer treatment via producing excess cellular reactive oxygen species (ROS) for the first time. The β-s...

As a chronic and lifelong disease, obesity not only significant impairs health but also dramatically shortens life span (at least 10 years). Obesity requires a life-long effort for the successful treatment because a number of abnormalities would appear in the development of obesity. Nanomaterials possess large specific surface area, strong absorpti...

The native human heart valve leaflet contains a layered microstructure comprising a hierarchical arrangement of collagen, elastin, proteoglycans and various cell types. Here, we review the various experimental methods that have been employed to probe this intricate microstructure and which attempt to elucidate the mechanisms that govern the leaflet...

Mesenchymal stem cell (MSC) transplantation is promising for repairing heart tissues post myocardial infarction (MI). In particular, paracrine effects of the transplanted MSCs have been highlighted to play major roles in heart regeneration by secreting multiple growth factors and immune-modulatory cytokines. Nevertheless, its therapeutic efficacy s...
