A Biomimetic Lubricant Captures Hyaluronic Acid In Situ to Regenerate Cartilage: From Bench to Bedside

Advanced Science, EarlyView.
(a) The outstanding lubricative properties of natural articular cartilage arise from a composite coating composed of HA, lubricin, and phospholipids at its surface. Notably, lubricin facilitates the enrichment of synovial HA onto cartilage surfaces, and HA complexes with phospholipids, a key component to maintain extremely low friction under high ...

Synaptic κ‐Ga2O3 Photodetectors for Privacy‐Enhancing Neuromorphic Computing

Advanced Science, EarlyView.
We report on a single‐element neuromorphic sensor based on the persistent photoconductivity (PPC) of κ‐phase Ga2O3 capable of sensing ultraviolet light and harnessing intrinsic data privacy. The approach establishes a materials‐enabled pathway toward compact, intelligent, and privacy‐enhancing optoelectronic hardware for next‐generation edge systems ...

Reduced Intracellular c-di-GMP Content Increases Expression of Quorum Sensing-Regulated Genes in Pseudomonas aeruginosa

Frontiers in Cellular and Infection Microbiology, 2017
Cyclic-di-GMP (c-di-GMP) is an intracellular secondary messenger which controls the biofilm life cycle in many bacterial species. High intracellular c-di-GMP content enhances biofilm formation via the reduction of motility and production of biofilm ...

Specificity of the Cyclic GMP-Binding Activity and of a Cyclic GMP-Dependent Cyclic GMP Phosphodiesterase in Dictyostelium discoideum [PDF]

, 1982
The nucleotide specificity of the cyclic GMP-binding activity in a homogenate of Dictyostelium discoideum was determined by competition of cyclic GMP derivatives with [8-3H] cyclic GMP for the binding sites.

Highly Vertically Oriented Graphene Microstrip Pads With Ultrahigh Through‐Plane Thermal Conductivity and Ultralow Compressive Modulus for Efficient Heat Dissipation

Advanced Science, EarlyView.
Vertically aligned graphene microstrip pads (GMPs) break the traditional thermomechanical trade‐off in thermal interface materials. It simultaneously achieves an ultrahigh through‐plane thermal conductivity of 565.92 W m−1 K−1 and an ultralow compressive modulus below 115.16 kPa.

NosP Modulates Cyclic-di-GMP Signaling in Legionella pneumophila

, 2019
Biofilms form when bacteria adhere to a surface and secrete an extracellular polymeric substance. Bacteria embedded within a biofilm benefit from increased resistance to antibiotics, host immune responses, and harsh environmental factors.

PIEZO1 is Required for Acute Myeloid Leukemia Progression and Leukemia Stem Cell Maintenance via HIF1A‐SLC7A11 Axis‐Mediated Ferroptosis Defense

Advanced Science, EarlyView.
This study identifies the mechanosensor PIEZO1 as a key factor in promoting acute myeloid leukemia progression and uncovers a ferroptosis defense system mediated by PIEZO1‐HIF1A‐SLC7A11 axis that is essential for leukemia stem cell maintenance. This ferroptotic defense system may represent a unique vulnerability for leukemia stem cells, providing a ...

Nucleic Acid Therapeutics for “Undruggable” Cancer Targets: Mechanisms, Challenges, and Prospects

Advanced Science, EarlyView.
Nucleic acid therapeutics bypass the structural limitations of conventional drugs by targeting mRNA rather than proteins. This review examines how antisense oligonucleotides, siRNAs, miRNAs, aptamers, and mRNA vaccines intervene against historically undruggable oncoproteins including Ras, MYC, and p53, highlighting mechanistic advances, delivery ...
