Percutaneous Closure Device for the Carotid artery: An integrated review and design analysis.

Endovascular thrombectomies (EVTs) are the current standard of care therapy for treating acute ischemic strokes. While access through the femoral or radial arteries is routine, up to 20% of EVTs through these sites are unable to access the cerebral vasculature on the first pass. These shortcomings are commonly due to tortuous vasculature, atherosclerotic arteries, and type III aortic arch, seen especially in the elderly population.

Aerogel from Sustainably Grown Bacterial Cellulose Pellicles as a Thermally Insulative Film for Building Envelopes.

Improving building energy performance requires the development of new highly insulative materials. An affordable retrofitting solution comprising a thin film could improve the resistance to heat flow in both residential and commercial buildings and reduce overall energy consumption. Here, we propose cellulose aerogel films formed from pellicles produced by the bacteria as insulation materials.

Rheology of regenerated cellulose suspension and influence of sodium alginate.

Cellulosic colloidal suspensions present unique opportunities for rheological modification of complex fluids. In this work, the rheological behavior of regenerated cellulose (RC) suspensions, including their oscillating shear and time-dependent behavior, as well as yield stress, were studied. The rheological effects of sodium alginate's addition to aqueous RC solutions subject to shear flow were investigated.

Quantifying the resolution of spatial and temporal representation in children with 22q11.2 deletion syndrome.

Objectives: Our ability to generate mental representation of magnitude from sensory information affects how we perceive and experience the world. Reduced resolution of the mental representations formed from sensory inputs may generate impairment in the proximal and distal information processes that utilize these representations. Impairment of spatial and temporal information processing likely underpins the non-verbal cognitive impairments observed in 22q11.

Plasmonic Metamaterial Gels with Spatially Patterned Orientational Order via 3D Printing.

Optical properties can be programmed on mesoscopic scales by patterning host materials while ordering their nanoparticle inclusions. While liquid crystals are often used to define the ordering of nanoparticles dispersed within them, this approach is typically limited to liquid crystals confined in classic geometries. In this work, the orientational order that liquid crystalline colloidal hosts impose on anisotropic nanoparticle inclusions is combined with an additive manufacturing method that enables engineered, macroscopic three-dimensional (3D) patterns of co-aligned gold nanorods and cellulose nanocrystals.

Seeing Eye to Eye With Threat: Atypical Threat Bias in Children With 22q11.2 Deletion Syndrome.

Individuals with 22q11.2 deletion syndrome (22q11DS) show high rates of anxiety associated with their increased risk of developing schizophrenia. Biased attention is associated with anxiety and is important to investigate in those with 22q11DS given this association.

On open and closed convex codes.

Neural codes serve as a language for neurons in the brain. () which arise from the pattern of intersections of collections of open (or closed) convex sets in Euclidean space, are of particular relevance to neuroscience. Not every code is open or closed convex, however, and the combinatorial properties of a code that determine its realization by such sets are still poorly understood.

Regenerated cellulose-dispersed polystyrene composites enabled via Pickering emulsion polymerization.

Cellulose composites are an important class of polymeric composites due to their renewable, biodegradable feedstock, and tend to have exceptional properties due to peculiar increase of the matrix-filler interface. In this work, a new breed of colloids enabled by regenerated cellulose (RC) was used to prepare polystyrene/cellulose composites. Specifically, an oil-in-water Pickering emulsion of styrene stabilized by RC was prepared, followed by polymerization of styrene, allowing us to obtain a uniformly dispersed PS/RC composite.
