Diagnostic value of transcranial ultrasonography for selecting subjects with large vessel occlusion: a systematic review

The Ultrasound Journal, 2019
Introduction A number of pre-hospital clinical assessment tools have been developed to triage subjects with acute stroke due to large vessel occlusion (LVO) to a specialised endovascular centre, but their false negative rates remain high leading to ...

Multiplex Modular Nanorobotic Systems with Catalytic Activity under Magnetic Navigation

Advanced Functional Materials, EarlyView.
We present modular nanorobots composed of a magnetic propulsion module and different extension modules carrying functional activities, assembled via DNA base pairing. The system integrates propulsion, optical tracking, enzymatic catalysis, and cell docking in a programmable manner.

Design Strategies and Emerging Applications of High‐Performance Flexible Piezoresistive Pressure Sensors

Advanced Functional Materials, EarlyView.
Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks

First level library and/or information science education and training at South African universities and technikons : developments in specialisation

South African Journal of Libraries and Information Science, 2013
The literature of the early 1990s observed a general lack of differentiation and specialisation at the basic qualification level in library and/or information science education and training in South Africa. This paper draws from an empirical study on first level LIS qualifications at South African universities and technikons to examine developments in ...

Ultrasmall High‐Entropy Materials: Nanoscale Effects, Synthesis, and Mechanistic Insights

Advanced Functional Materials, EarlyView.
This review article focuses on sub‐10 nm high‐entropy materials that combine nanoscale design with complex compositions for next‐generation applications. ABSTRACT Ultrasmall high‐entropy nanomaterials (USHENMs, <10 nm) merge multicomponent chemistry with size‐dependent effects, forming a distinct class of materials with unprecedented properties.

Chamber‐Specific Decellularized Extracellular Matrices Differentially Modulate Cardiomyocyte Subtypes to Drive Engineered Heart Tissue Development and Function

Advanced Healthcare Materials, EarlyView.
Chamber‐specific decellularized extracellular matrices (ECMs) were developed, preserving native proteomic profiles of ventricular and atrial myocardium. These innate biochemical cues differentially modulate cardiomyocyte subtypes to drive engineered heart tissue development and function, highlighting the importance of incorporating regional ECM cues in

Annuntiationis Puer. O Menino na Anunciação, em Portugal [PDF]

Via Spiritus, 2010
A rare form of representation of the evangelical episode of the Annunciation is one in which we see a tiny naked Child, coming down from heaven towards the Virgin Mary. Here are presented, in chronological order, the images of that kind of representation

A Fully Human Engineered Bone Niche With Endogenous Osteoclastogenesis Reveals Osteoclast‐Dependent Osteomimicry in Prostate Cancer Cells

Advanced Healthcare Materials, EarlyView.
A human 3D bone niche integrating osteoblasts and osteoclasts enables co‐culture with prostate cancer cell lines and patient‐derived organoids. The engineered niche (i) models aspects of reciprocal phenotypic regulation between osteoblasts and cancer cells, (ii) captures osteoclast‐enhanced osteomimicry in tumor cells, and (iii) establishes a ...
