Translational Considerations for Injectable Biomaterials and Bioscaffolds to Repair and Regenerate Brain Tissue

Advanced Healthcare Materials, EarlyView.
The repair and regeneration of brain tissue faces both biological and technical challenges. Injectable bioscaffolds offer new opportunities to stimulate tissue regrowth in the brain by recruiting neural stem cells. Here, the translational issues are reviewed that need to be address to advance this promising new therapeutic approach from the bench to ...

Non-valvular atrial fibrillation and stroke : implications for management [PDF]

, 1995
Nonvalvular Atrial Fibrillation is more prevalent with increasing age. It is associated with a six-fold excess risk of stroke; and a cumulative lifetime stroke risk of 35%. 15% of ischaemic strokes are directly attributable to it.

Re-education of upper limb function post-stroke, using interative learning control (ILC) mediated by functional electrical stimulation (FES)

, 2007
Introduction There is a body of clinical evidence to support the use of FES to improve motor control (De Kroon et al. 2002) and theoretical support from neurophysiology (Burridge & Ladouceur 2001) and motor learning research (Schmidt & Lee 1999).

Ativação adrenérgica alterada se associa à recuperação anormal da Frequência Cardíaca? Is abnormal adrenergic activation associated with abnormal Heart Rate Recovery?

Arquivos Brasileiros de Cardiologia, 2012
FUNDAMENTO: Frequência Cardíaca de Recuperação (RFC) reflete a capacidade do sistema cardiovascular de reverter a supressão vagal ocasionada pelo exercício. A cintilografia com metaiodobenzilguanidina (I¹²³ MIBG) avalia a inervação e ativação adrenérgica

Long‐Term Hydrophilic, Anti‐Clotting, and Anti‐Fibrotic Dynamic Covalent Silicone‐Based Biomaterials

Advanced Healthcare Materials, EarlyView.
Dynamic covalent crosslinking of a Schiff‐base silicone elastomer with hydrazide‐functionalized polymers is demonstrated to improve the long‐term hydrophilicity as well as the anti‐fouling and anti‐clotting properties of PDMS implants. The hydrazone‐functionalized material prevents hydrophobic recovery, resists clotting, and significantly reduces ...

Neutrophil‐Mimetic MRI Enables Ultra‐Early Detection of Vascular Inflammation After Stroke

Advanced Healthcare Materials, EarlyView.
In this study, we developed neutrophil‐mimetic MRI probes that detect ultra‐early neuroinflammation following ischemic stroke by targeting E‐selectin. Within seconds of their injection, these microparticles mimic initial leukocyte adhesion to the activated cerebral endothelium.

The meaning and experience of participation in stroke survivors. [PDF]

, 2013
In the UK, one in four men and one in five women will be expected to have experienced a stroke by the time they are eighty five (Daniel, Wolfe, Busch, & McKevitt, 2009).

Self‐Powered Flexible Triboelectric‐Gated Ion‐Gel Transistor for Neuromorphic Tactile Sensing and Human Activity Recognition

Advanced Materials, EarlyView.
A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.

Dexime: A Selectively Enzyme‐Degradable Hydrogel for Protein Therapeutic Release

Advanced Materials, EarlyView.
A dextrin‐oxime hydrogel (dexime) is produced using ketone or aldehyde modified dextrin and tetra‐oxyamine modified poly(ethylene glycol). The rheological and mechanical properties of dexime are tunable. Dexime is injectable, cytocompatible, hydrolytically stable, and selectively degradable by α‐amylase.
