Robust Controlled Degradation of Enzyme Loaded PCL‐Based Fibrous Scaffolds Toward Scarless Skin Tissue Regeneration

open access: yesAdvanced Science, EarlyView.
A novel biodegradable wound dressing (E‐PCLs) based on polycaprolactone (PCL) and an enzyme complex (RHP‐BCL) is developed using a fiber microfluidic electrospinning technique. The dressing achieves complete degradation within 14 days, eliminates microplastic residues, and promotes scar‐free healing (99% in 21 days).

Calpain‐2‐Mediated Endothelial Focal Adhesion Disruption in Thoracic Aortic Dissection

open access: yesAdvanced Science, EarlyView.
The elevated expression of Capn2 in endothelial cells activates focal adhesion signaling by cleaving Talin1 and assembling Itgav, which compromises the integrity of the endothelial barrier and induces vascular inflammation. Inhibition of calpain through both pharmacological and transgenic approaches has effectively suppressed the onset and progression ...

Mechanical Biomimetic Nanocomposites for Multidimensional Treatment of Arterial Thrombosis

open access: yesAdvanced Science, EarlyView.
In this study, a mechanical biomimetic nanocomposite is developed, guided by photoacoustic imaging, to achieve highly efficient and safe thrombolysis through the synergistic effects of photothermal therapy and pharmacological intervention. Most notably, the nanoparticle improves the microenvironment of arterial thrombi, marked by high shear stress and ...

Polyaspartic Acid‐Calcium‐Lanthanum Complexes Induce Antibacterial Remineralization of Dentin and In‐Depth Occlusion of Dentinal Tubules

open access: yesAdvanced Science, EarlyView.
Polyaspartic acid‐calcium‐lanthanum (PAsp‐Ca‐La) complexes could induce antibacterial remineralization of demineralized dentin and in‐depth occlusion of dentinal tubules (DTs) with lanthanum‐doped hydroxyapatite (La‐HAp) via polyelectrolyte‐cation complexes pre‐precursor (PCCP) process, allowing the release of La3+ in response to acids generated by ...

Rough and Tough: How Particle Surface Roughness Affects Liquid Marble Formation and Stability

open access: yesAdvanced Science, EarlyView.
This study investigates the influence of particle surface roughness on the formation and stability of liquid marbles using well‐defined colloidal supraparticles as model systems. Increasing surface roughness enhances the interfacial contact angle, improves mechanical stability by increasing deformation resistance upon impact, and enables liquid marble ...

Targeted Dual‐Responsive Liposomes Co‐Deliver Jolkinolide B and Ce6 to Synergistically Enhance the Photodynamic/Immunotherapy Efficacy in Gastric Cancer through the PANoptosis Pathway

open access: yesAdvanced Science, EarlyView.
Schematic model of CJP–TiN liposomes for gastric cancer (GC) treatment. Internalizing RGD peptide (iRGD) targets tumor cells, while Chlorin e6 (Ce6) generates reactive oxygen species (ROS). Jolkinolide B (JB) activates the PANoptosis pathway via caspase‐8, enhancing GC cell death and immune response, transforming “cold tumors” into “hot tumors” by ...

Platelet-Activating Factor

, 2016
Platelet-activating factor (PAF) is a phospholipid produced by a variety of cells including platelets, endothelial cells, neutrophils, monocytes and macrophages. It has a wide range of potent biological activities including wound healing, physiological inflammation, apoptosis, angiogenesis, reproduction and long-term potentiation.

COVID‐19, microthromboses, inflammation, and platelet activating factor

Biofactors, 2020
Recent articles report elevated markers of coagulation, endothelial injury, and microthromboses in lungs from deceased COVID‐19 patients. However, there has been no discussion of what may induce intravascular coagulation.
