In vitro co-culture and ex vivo organ culture assessment of primed and cryopreserved stromal cell microcapsules for intervertebral disc regeneration
(2019)Priming towards a discogenic phenotype and subsequent cryopreservation of microencapsulated bone marrow stromal cells (BMSCs) may offer an attractive therapeutic approach for disc repair. It potentially obviates ... -
In vivo dynamics of the internal fibrous structure in smooth adhesive pads of insects
(2012)Many insects with smooth adhesive pads can rapidly enlarge their contact area by centripetal pulls on the legs, allowing them to cope with sudden mechanical perturbations such as gusts of wind or raindrops. The short time ... -
Incorporation of collagen and hyaluronic acid to enhance the bioactivity of fibrin-based hydrogels for nucleus pulposus regeneration
(2018)Hydrogels, such as fibrin, offer a promising delivery vehicle to introduce cells into the intervertebral disc (IVD) to regenerate damaged disc tissue as a potential treatment for low back pain. However, fibrin lacks key ... -
Inferred Threat and Safety: Symbolic Generalization of Human Avoidance Learning
(2011)Symbolic generalization of avoidance may underlie the etiology and maintenance of anxiety disorders. The aim of the present study was to demonstrate inferred threat-avoidance and safety (non-avoidance) behaviours that occur ... -
The Influence of Additive Manufacturing Processes on the Performance of a Periodic Acoustic Metamaterial
(2019)Advancements in 3D print technology now allow the printing of structured acoustic absorbent materials at the appropriate microscopic scale and sample sizes. The repeatability of the fundamental cell unit of these metamaterials ... -

The influence of construct scale on the composition and functional properties of cartilaginous tissues engineered using bone marrow-derived mesenchymal stem cells.
(2012)Engineering cartilaginous tissue of a scale necessary to treat defects observed clinically is a well-documented challenge in the field of cartilage tissue engineering. The objective of this study was to determine how the ... -
The influence of expansion rates on mandibular distraction osteogenesis: a computational analysis
(Springer, 2007)Mandibular distraction osteogenesis is a clinical procedure used for modifying the mandibular geometry when problems of dental overcrowding and arch shrinkage occur. The objective of this study is to use a computational ... -
Influence of Mechanical Environment on Limbal and Corneal Epithelial Cells
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2021)Corneal blindness is the 4th leading cause of blindness and the most transplanted tissue worldwide. Severe donor shortages and immune rejection has led to research into alternative therapies for corneal transplantation. ... -
Influence of micropatterned substrates on keratocyte phenotype
(2020)Substrate topographic patterning is a powerful tool that can be used to manipulate cell shape and orientation. To gain a better understanding of the relationship between surface topography and keratocyte behavior, surface ... -
The influence of plaque composition on underlying arterial wall stress during stent expansion: the case for lesion-specific stents
(2009)Intracoronary stent implantation is a mechanical procedure, the success of which depends to a large degree on the mechanical properties of each vessel component involved and the pressure applied to the balloon. Little ... -
Influence of polydimethylsiloxane substrate stiffness on corneal epithelial cells
(2019)Many cell types are known to modulate their behaviour in response to changes in material stiffness; however, little is known about how stiffness affects corneal epithelial cells. This study aims to investigate the response ... -
Influence of processing parameters on density, surface morphologies and hardness of as-built Ti-5Al-5Mo-5V-3Cr alloy manufactured by selective laser melting
(2022)Demand for new Ti alloys for AM is immense. Ti–5Al–5Mo–5V–3Cr (wt%), a β type Ti alloy is chosen for this study as it possesses excellent properties. Samples are manufactured using SLM technique. Relative density, surface ... -
The Influence of the Magnitude of Gravitational Acceleration on the Marangoni Convection about an Isolated Bubble under a Heated Wall
(2009)Thermocapillary or Marangoni convection is the liquid motion caused by surface tension variation in the presence of a temperature gradient along a gas–liquid or vapor–liquid interface. This work numerically ... -
The influence of ventilation tube design on the magnitude of stress imposed at the implant/tympanic membrane interface
(Elsevier, 2008)The design of ventilation tubes or grommets is thought to have a considerable influence on their performance. A computational model (finite element method) was used to investigate the significance of four design parameters ...
