Smartphone‐Guided Visible Light Modulation of RSNOs for Antimicrobial Activity via Controlled Nitric Oxide Release

Advanced Science, EarlyView.
A light‐activated catheter insert combines antimicrobial blue light with nitric oxide release to generate complementary oxidative and nitrosative stress, producing potent broad‐spectrum antimicrobial activity. The approach achieves greater than 4‐log reductions in bacterial and fungal viability and significantly reduces Staphylococcus aureus ...

Enhanced group-based wireless ad-hoc sensor network protocol

International Journal of Distributed Sensor Networks, 2016
Communication is the major energy consumption source in wireless ad-hoc sensor networks. Thus, an efficient trade-off between the energy cost of the communication and network’s performance is a key challenge in conceiving a wireless ad-hoc sensor network.

Astrocytes Coordinate Neurovascular Coupling During Prolonged Sensory Demand via AQP4/TRPA1/BEST1/D‐Serine Signaling

Advanced Science, EarlyView.
Neuronal activation leads to astrocytic transient volume changes, activating transient receptor potential ankyrin 1 (TRPA1) channels, leading to Ca2+ influx. Activation of TRPA1 causes the release of D‐serine through BEST1. Finally, the augmented extracellular levels of D‐serine boost neuronal activity by binding GluN1‐containing NMDARs, leading to CBV

Drug Repurposing for Treating NCOR‐Related Intellectual Disability

Advanced Science, EarlyView.
An autism‐associated NCOR1 heterozygous mutation upregulates NRGs and activates NRG backward signaling in hypothalamic GABAergic neurons in mouse models, leading to Gabra2 downregulation and cognitive deficits, which can be therapeutically targeted by repurposing FDA‐approved drugs.

Sea Cucumber‐Inspired Double‐Network Biopolymer Hydrogels for Programmable Soft Machines

Advanced Science, EarlyView.
Inspired by the mutable dermis of sea cucumbers, the collagen‐alginate double‐network elastomeric (CoDE) hydrogel achieves programmable, recoverable, and functional mechanical behavior. The CoDE hydrogel mimics the mutable stiffness of the sea cucumber dermis through a densified collagen cryogel scaffold that is secondarily reinforced by a dissipative,
