The biomechanical properties of the brain microenvironment, which is composed of different neural cell types, the extracellular matrix, and blood vessels, are critical for normal brain development and neural functioning. Stiffness, viscoelasticity and spatial organization of brain tissue modulate proliferation, migration, differentiation, and...

Microglia, the resident macrophages of the central nervous system, are key players in neuroinflammation and neurodegenerative diseases, such as Alzheimer’s and Parkinson’s. These cells represent promising cellular targets for therapeutic intervention, therefore a detailed cellular biological knowledge of microglia is of paramount importance....

Cartilage degeneration is a major cause of chronic disability and its treatment usually involves highly invasive procedures. To address this issue, three-dimensional (3D) bioprinting was introduced as a promising tissue engineering approach. However, the structures fabricated with this method are static and lack the dynamic response of native...

Purpose: Patients with tracheal lesions that exceed half of the trachea’s total length require a tracheal substitute. Tissue engineering, using either synthetic materials or decellularized tracheal tissue, opens up new possibilities for generating tracheal substitutes. Decellularization, a procedure in which the tissue's...

Extrusion-based 3D printing followed by debinding and sintering is a powerful approach that allows for the fabrication of porous scaffolds from materials (or material combinations) that are otherwise very challenging to process using other additive manufacturing techniques. Iron is one of the materials that have been recently shown to be...

Additively manufactured biodegradable porous iron has been only very recently demonstrated. Two major limitations of such a biomaterial are very low biodegradability and incompatibility with magnetic resonance imaging (MRI). Here, we present a novel biomaterial that resolves both of those limitations. We used extrusion-based 3D printing to...

In recent decades, an increasing number of tissue engineered bone grafts have been developed. However, expensive and laborious screenings in vivo are necessary to assess the safety and efficacy of their formulations. Rodents are the first choice for initial in vivo screens but their size limits the dimensions and number of the bone grafts...

The use of allografts for the treatment of critical size cartilage defects holds disadvantages including the limited number of donors and the compromised chondrocyte viability. These limitations have prompted researchers to explore different options, such as cartilage engineering. Bioprinting, a promising tissue engineering technique, could be...

For the treatment of large bony defects, no perfect solution has been yet found, partially due to the unavailability of ideal bone implants. Additively manufactured (AM) biodegradable porous metals provide unprecedented opportunities to fulfil the requirements for ideal bone implants to be used in such treatments. Firstly, the multi-scale...

In an effort to further evaluate the effects of Ecological Interface Design on acquiring expertise, this paper presents the results of an investigation into how Ecological Interface Design could possibly promote discovery learning processes in the Air Traffic Control domain through the application of an instructional design model, and how it...

Context. In times where human kind is facing serious challenges due to global warming, scarcity of natural resources and inequality, to continue producing food, especially meat, as it is now done, does not seem sustainable. For people that want to continue enjoying their delicious piece of steak, the manner in which meat is sourced will need to...

Partially due to the unavailability of ideal bone substitutes, the treatment of large bony defects remains one of the most important challenges of orthopedic surgery. Additively manufactured (AM) biodegradable porous metals that have emerged since 2018 provide unprecedented opportunities for fulfilling the requirements of an ideal bone...

To guide the natural bone regeneration process, bone tissue engineering strategies rely on the development of a scaffold architecture that mimics the extracellular matrix and incorporates important extracellular signaling molecules, which promote fracture healing and bone formation pathways. Incorporation of growth factors into particles...

Additively manufacturing (AM) opens up the possibility for biodegradable metals to possess uniquely combined characteristics that are desired for bone substitution, including bone-mimicking mechanical properties, topologically ordered porous structure, pore interconnectivity and biodegradability. Zinc is considered to be one of the promising...

Biodegradable porous magnesium (Mg) scaffolds are promising for application in the regeneration of critical-sized bone defects. Although additive manufacturing (AM) carries the promise of offering unique opportunities to fabricate porous Mg scaffolds, current attempts to apply the AM approach to fabricating Mg scaffolds have encountered some...

In this study, we attempt to specify the cognitive support behavior of a previously designed embodied conversational agent coach that provides learning support to low-literates. Three knowledge gaps are identified in the existing work: an incomplete specification of the behaviors that make up ‘support,’ an incomplete specification of how this...

Clinical treatments for the repair of osteochondral defects (OCD) are merely palliative, not completely curative, and thus enormously unfulfilled challenges. With the in-depth studies of biology, medicine, materials, and engineering technology, the conception of OCD repair and regeneration should be renewed. During the past decades, many...

Atherosclerosis is an inflammatory disease characterised by the formation of plaque in the intimal layer of the artery. The plaque is made of a lipid rich necrotic core which is covered by a collagen rich fibrous cap. If this fibrous cap ruptures, it can lead to sudden thrombotic occlusion of the artery. Rupture of the fibrous cap is linked to...

Although many studies have been performed on porous absorbable iron scaffolds created by the space holder method, no studies have considered the influence of variations in space holders on absorbable scaffolds. The present study aimed to clarify the effects of space holder particle size and volume fraction, on the pore structure, resultant...

Society is stuck in daily routines, led by social norms and conventions. Often we are unaware of this, while life can be much richter if we would subvert from these routines every once in a while. These routines prevent us from seeing everything that there is. Our expectations need to be subverted. <br/><br/>Usually it is reserved for artists to...
