Bio‐Inspired, Zwitterionic Copolymers with Amphiphilic Character

Macromolecular Rapid Communications, EarlyView.
Zwitterionic copolymers based on arginine‐derived monomers are produced by xanthate‐supported photo‐iniferter reversible‐addition‐fragmentation chain‐transfer polymerization. Experiments in relevant conditions show that the designed (co)polymers hardly interact with biologically relevant proteins and enzymes such as bovine serum albumine (BSA), fetal ...

Toward Dynamic Liquid Cell Scaffold: Photoreversible Ion Gels Exhibiting Light‐Induced Sol‐Gel Transitions

Macromolecular Rapid Communications, EarlyView.
Light‐programmable, non‐cytotoxic ion gels based on ABC triblock copolymers undergo photoreversible sol‐gel transitions, crossing the rheological boundary (tan δ ∼ 1). UV–vis light irradiation modulates the lifetime of reversible junctions, switching the scaffold between liquid‐like and solid (gel)‐like states.

Local Field Aperiodic Spectral Power Modulated by Deep Brain Stimulation in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Aperiodic spectral broadband power has been described recently as reflecting Parkinson's disease (PD) severity. It has therefore become an increasing focus of research interest in the context of the new adaptive deep brain stimulation (DBS) approach.

Respiration Can Trigger Cerebrovascular Reactivity: A Novel Method to Quantify Cerebrovascular Resistance Dynamics Using Real‐Time Phase‐Contrast MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To directly quantify respiration‐driven cerebrovascular resistance dynamics (CRD) using a gas‐free MRI framework based on the internal‐to‐external artery carotid flow ratio (ratio_Q). Theory and Methods Two independent datasets (n = 10 and n = 17) were used to evaluate repeatability and to compare breathing conditions.
