Inhalational or total intravenous anaesthesia: is total intravenous anaesthesia useful and are there economic benefits? [PDF]
, 2011 PURPOSE OF REVIEW: The comparison of inhalational and intravenous anaesthesia has been the subject of many controlled trials and meta-analyses. These reported diverse endpoints typically including measures of the speed and quality of induction of ...

Beyond Bioactive Glass Composition: Using Morphology to Improve in Vitro and in Vivo Performance
Advanced Healthcare Materials, EarlyView.Bioactive glasses can easily be shaped into granules, spheres, discs, fibers, or three‐dimensional scaffolds. The resulting morphology not only affects handling properties; it has a direct influence on various glass properties, including results of acellular immersion experiments or in vitro studies with cells or bacteria, but also on in vivo ...

Use of the Neurological Pupil Index to Predict Postoperative Visual Function After Resection of a Tuberculum Sellae Meningioma: A Case Report. [PDF]
, 2019 The Neurological Pupil index (NPi) is a standardized method for evaluating pupil reactivity that removes inter-examiner variability. Changes in the NPi can predict clinical deterioration in patients with traumatic brain injury (TBI); however, its use to ...

Advanced Healthcare Materials, EarlyView.Neural electrodes face a mechanical mismatch with brain tissue. This study proposes a bioelectromechanical coupling strategy using an ultra‐flexible electrode designed for synchronized motion. Optimized to match brain tissue stiffness, it achieves dual signal acquisition and micromotion sensing, with characterized interfacial forces and piezoresistive ...

Advanced Materials, EarlyView.Hydrogels demonstrate material properties that mimic the mechanical and chemical environments of biological tissues. Yet, they face challenges during their integration into 3D interfaces. By identifying a class of thermoplastic hydrogels, a strategy is developed to pattern hydrogels in thermally drawn fibers.
