Bio‐Inspired Artificial Ionic Mechanoreceptor

Advanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,

Implantable Sensors for Heart Failure [PDF]

Circulation: Arrhythmia and Electrophysiology, 2010
Heart failure (HF) affects more than 5 million Americans, and acute decompensated heart failure (ADHF) has emerged as the leading cause of hospitalization among people over the age of 65 years.1 Importantly, HF is a leading public health concern, and hospitalization expenses related to management of ADHF impose a substantial financial burden on the ...

Right heart failure after left ventricular assist device implantation: latest insights and knowledge gaps on mechanism and prediction [PDF]

Heart failure is a global health concern, with many patients being unresponsive to medical therapies. In end-stage disease, left ventricular assist devices (LVADs) offer an alternative to transplantation, yet their clinical course remains unfavorable ...

Preferential Interfacial Engineering of Hydrogels via Interdigitated Nanoparticle Assembly

Advanced Functional Materials, EarlyView.
Robust surface functionalization of hydrogel surfaces is performed via interdigitated metal nanoparticle assembly, inducing strong affinity with the hydrogel matrix. The partially exposed nanoparticle domains act as interfacial nanobridges that mediate both chemical and physical bonding with diverse materials, including small molecules, fluorous ...

An Epigenetic Fate Converter Based on Nuclei‐Targeting Lipid Nanoparticles Drives Neuronal Programming of Stem Cells for Spinal Cord Repair

Advanced Functional Materials, EarlyView.
Schematic illustration of LNP‐MPG nuclei‐targeting delivery of HMW‐FGF2 promoting histone acetylation to regulate the fate of DPSCs and treat spinal cord injury. LNPs components include pHMW‐FGF2 plasmid, DSPC, Dlin‐MC3‐DMA, cholesterol, and PEG2000, and are modified with MPG to form HMW‐FGF2@LNP‐MPG (HLM). HLM nuclei‐targets DPSCs to deliver HMW‐FGF2,

Temporal trajectory of plasma miRNA during the peri-implantation stage: comparing implantation success and failure in single frozen–thawed blastocyst transfers

Frontiers in Endocrinology
BackgroundImplantation failure is the most common cause of pregnancy failure and is a major limiting factor in assisted reproduction. Plasma microRNA (miRNA) expression profiles show dynamic changes among individuals with successful implantation. However,
