X‐Ray Tomography Analysis of Damage Mechanisms in Metal Matrix Syntactic Foams During Compression

Advanced Engineering Materials, EarlyView.
In situ synchrotron X‐ray tomography is used to investigate the internal damage mechanisms of AlSi12 metal matrix syntactic foam with ceramic hollow spheres during compressive loading. It is concluded that a homogeneous distribution of the second‐phase filler material results in a sequential collapse in a localized region; this leads to controlled and ...

Micropleated Nanofibrous Filters for High‐Efficiency Submicron Aerosol Filtration: A Comparative Study with Chemical, Biological, Radiological, and Nuclear Gas Mask Filters

Advanced Engineering Materials, EarlyView.
This study presents micropleated filters manufactured by needleless electrospinning. Nanofibers are deposited onto uniaxially pre‐stretched substrates that contract upon release, forming densely packed micropleats. This architecture increases effective surface area without enlarging the filter size, achieving quality factors comparable to those of ...

Development and Preliminary In Vivo Study of 3D‐Printed Bioactive Glass Scaffolds with Trabecular Architecture

Advanced Engineering Materials, EarlyView.
This study reports the fabrication of trabecular bioactive glass scaffolds (composition “1d”: 46.1SiO2‐28.7CaO‐8.8MgO‐6.2P2O5‐5.7CaF2‐4.5Na2O wt%) through vat photopolymerization and the relevant results from mechanical testing and in vivo implantation procedures in rabbit femora, showing great promise for bone tissue engineering applications.

Nuclear movement in multinucleated cells

Development, 2022
ABSTRACTNuclear movement is crucial for the development of many cell types and organisms. Nuclear movement is highly conserved, indicating its necessity for cellular function and development. In addition to mononucleated cells, there are several examples of cells in which multiple nuclei exist within a shared cytoplasm.

Chemotactic cell movement during development

Current Opinion in Genetics & Development, 2003
Chemotaxis is an important mechanism controlling cell migration over either short or long distances during different developmental processes. Small rapid diffusing chemo-attractants are detected through serpentine, G protein coupled receptors through graded activation of receptors along the length of the cell.

Cyclic GMP and Cell Movement

Nature, 1973
THE movement of mammalian cells can be inhibited by agents which mimic or produce increases in the intracellular levels of cyclic 3′,5′-adenosine monophosphate (cyclic AMP)1,2. Goldberg and coworkers3,4 have proposed that in a number of cell types cyclic 3′,5′-guanosine monophosphate (cyclic GMP) promotes cellular events that are antagonistic to those ...

Cell-to-cell movement of plant viruses

Trends in Microbiology, 1993
To establish an infection, most plant viruses move from cell to cell in the plant. Virus-encoded movement proteins mediate this process and appear to use two mechanisms for transport. Both mechanisms involve interaction with and potential modification of plant intercellular connections, the plasmodesmata.

Cell Movement and Cell Behaviour

Journal of Cell Science, 1987
ABSTRACT John Lackie’s course on cell behaviour delivered to Senior Honours Cell Biology students at Glasgow University is largely responsible for the predominance of young Glaswegian scientists at British conferences on cell behaviour.
