A Disulfide‐Sticker Strategy for Marine Adhesive Coatings: From Deciphering Self‐Assembly Mechanism to Functional Application in Hair Regeneration

Advanced Science, EarlyView.
A disulfide‐sticker strategy, coupled with Ca2+ coordination, drives the hierarchical self‐assembly of a recombinant scallop adhesive protein into fishnet‐like nanostructures, affording a coating with versatile wet adhesion and intrinsic antioxidant activity. This biocompatible coating markedly promotes hair regeneration by activating follicular niches,

Unraveling Bone‐Skin Crosstalk Enables miRNA Nanoformulation for Cutaneous Neurovascular Reconstruction in Diabetic Mice

Advanced Science, EarlyView.
This study unravels that bone fracture accelerates diabetic wound healing by releasing exosomal microRNA (miR‐130b‐3p). To mimic this bone‐skin crosstalk, we engineered a self‐assembling agomir‐130b‐3p nanocomplex. Delivered via a photocrosslinkable hydrogel, this bio‐inspired therapy provides sustained localized agomir release.

A Novel IDO1/NE Dual Inhibitor, IMM‐H018 Prevents the Primary and Secondary Sepsis and Ameliorates the Kidney Injury Through Inhibiting the Cytokine Storm and Microthrombosis, and Reversing Immunosuppression

Advanced Science, EarlyView.
IMM‐H018, a dual IDO1/NE inhibitor, demonstrates potent therapeutic efficacy in sepsis by simultaneously targeting excessive inflammation and immune dysfunction. It prevents both primary and secondary sepsis through anti‐inflammatory, immune‐restoring, and renoprotective mechanisms, reducing organ damage, improving immune homeostasis, preserving kidney

Microenvironment‐Responsive Nanomedicine Enables Vertical Modulation of Mitochondrial Pathological Networks in Myocardial Ischemia–Reperfusion Injury

Advanced Science, EarlyView.
A mitochondria‐targeted, microenvironment‐responsive nanoplatform enables pH/ROS‐triggered co‐delivery of berberine and isoliensinine to orchestrate ROS scavenging, inflammation suppression, and apoptosis inhibition. This vertical modulation of mitochondrial pathological networks preserves mitochondrial function and effectively mitigates myocardial ...

Vascular Endothelium and Ca2† Antagonists

Journal of Cardiovascular Pharmacology, 1988
Endothelial cells can release both relaxing and contracting factors. Since the release of endothelium-dependent relaxing factor is prevented by incubation in Ca2+-free solution and can be triggered by the Ca2+ ionophore A 23187, it must require an increase in cytoplasmic Ca2+ concentration in the endothelial cells.

Vascular Grafts and the Endothelium

Endothelium, 2006
This article discusses the importance of the endothelium for successful vascular grafts derived from both native arteries and synthetic materials. It also discusses the fundamental strategies to endothelialize synthetic grafts in animal experiments and in the clinic, as well as the use of endothelial progenitor cells (EPCs), bone marrow-derived cells ...

Estrogens and the Vascular Endothelium

Annals of the New York Academy of Sciences, 2002
Abstract: Estrogens exert important regulatory functions on vessel wall components, which may contribute to the increased prevalence and severity of certain chronic inflammatory and autoimmune diseases in females and the lower cardiovascular risk observed in premenopausal women. Endothelial cells have been recently identified as targets for estrogens,

Cryofixation of vascular endothelium

Journal of Electron Microscopy Technique, 1991
AbstractCryofixation refers to the immobilization of tissue components by the rapid removal of heat from the specimen, so that the structure is interred and stabilized in a natural embedding medium, namely, frozen (amorphous or microcrystalline) tissue water.

Role of the vascular endothelium

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1981
Abstract The intact vascular endothelial surface is considered to be ‘non-thrombogenic’, and blood platelets usually fail to adhere to it. In this role, the endothelium serves to maintain the integrity of the vascular system by preventing the escape of blood and by preventing the build-up of solid thrombus within the vessel, which ...

Vascular endothelium in atherosclerosis

Cell and Tissue Research, 2008
Their strategic location between blood and tissue and their constitutive properties allow endothelial cells (EC) to monitor the transport of plasma molecules, by employing bidirectional receptor-mediated and receptor-independent transcytosis and endocytosis, and to regulate vascular tone, cellular cholesterol and lipid homeostasis. These cells are also
