Tissue-material interactions : bioadhesion and tissue response
Diverse interactions between soft tissues and implanted biomaterials directly influence the success or failure of therapeutic interventions. The nature and extent of these interactions strongly depend on both the tissue and material in question and can presumably be characterized for any given …

Mechanical modeling of tissue response during early stage entubulated peripheral nerve regeneration
… capsule around the periphery of newly forming tissue. The second group of cells includes undifferentiated fibroblasts, Schwann cells, and endothelial cells which migrate into the fibrin core preceding axon elongation and synthesis of new nerve tissue. The pressure cuff hypothesis states that …

A Systems Approach to Modelling Tumour and Tissue Response in Radiotherapy for Head-and-Neck Cancer
The heterogeneity of patient responses to radiotherapy poses significant challenges in head-and-neck cancer (HNC), with outcomes ranging from severe toxicities to loco-regional recurrence (LRR). Multi-modal biomarker data—encompassing genetic, dosimetric, and imaging domains—offers an opportunity …

Pattern formation and essential responses for regeneration in planarians
… Planarians can robustly regenerate all tissues after injury, involving stem cells, patterning cues and a set of cellular and molecular responses collectively called the "missing tissue" or "regenerative" response. The missing tissue response has long been considered a fundamental …

Genetic analysis of tissue culture responses in barley (Hordeum vulgare L.).
… to screen barley genotypes for in vitro culture response; and to use the double haploid (DH) lines derived from the cross between responsive and unresponsive parental lines to confirm the location of previously reported QTL that control barley tissue response and search for additional QTL in a …

Investigation into the relationship between blunt impacts and bruising
… Impact results demonstrated a characteristic tissue response which was strongly influenced by anthropometric features. These features also appeared to influence the severity of resultant bruising observed.It was concluded that both the photography and colour pattern methods assessed may not be …

Mechanisms Regulating Pulmonary Sensitivity to Radiation
… </p><p>In these studies, we evaluated the dose-response relationship for survival and function injury among CBA/J, C57L/J, and C57BL/6J mouse strains. These strains were previously identified to represent the full spectrum of pulmonary pathology associated with acute radiation exposure to the …

Corn tissue nutrient response related to soil health and fertility
… tool used for managing plant nutrient health is tissue sampling and analysis. This tool is routinely used for some crops (e.g., especially specialty crops) for diagnosing plant nutrient needs and direct fertilizer decisions. End of season yield response to fertilizer may be improved by using both …

In Vivo Wear Performance of Highly-crosslinked Polyethylene in Total Hip Arthroplasty
… wear and the associated periprosthetic tissue response remain one of the key issues in long-term THA outcomes; in fact, recent findings indicate that HXLPE components generate finer wear particles that seem to induce a stronger inflammatory cell response, potentially leading to …

Biocompatibility Investigations of Surgical Implant Alloys.
… released during corrosion and to determine the tissue responses elicited under in vitro and in vivo conditions. In vitro testing involved exposing cell cultures to varying concentrations of synthetic solutions based on the alloy’s chemical composition and independently to solutions of the …

Biomechanics of the cerebrum at finite strain : a tissue and cell level study/
… addresses the large strain nonlinear mechanical response of the cerebral cortex at the macroscopic tissue level and at the microscopic cell level. Unconfined uniaxial compression tests were conducted in vitro on cortical samples of porcine brains. The tests consisted of load-unload and relaxation …

Non-linearity and Dispersion Effects in Tissue Impedance during Application of High Frequency Electroporation-Inducing Pulsed Electric Fields
… predictability in homogeneous and heterogeneous tissue masses. Therapeutic IRE and H-FIRE utilize source and sink electrodes inserted into or around the tumor to deliver the treatment. Prediction of the ablation size, for a set of parameters, can be achieved by the use of pre-treatment planning …

The Effect of Ion Implantation on the Corrosive-Wear Resistance of Ti-6A1-4V.
… corrosion products or wear debris can elicit a tissue response and may have a systemic effect in the body after a long period of exposure. These problems are of vital concern, especially with respect to prosthetic total joint replacements, since these implants should remain in situ for the life …

Materials selection and processing for reliable neural interfaces
… neural activity in vivo while evoking minimal tissue response. Additionally, electrodeposition of biocompatible metals onto the fiber-electrode tips can be implemented to increase the signal-to-noise ratio (SNR). Here, I describe the electroplating of gold onto the fiber-tips of tin and …

Cephalometric Analysis of Soft Tissue Profile Change Associated with Orthodontics and Orthognathic Surgery : A Long-Term Study
… orthognathic surgical treatment upon the soft tissue profile, and to determine the correlation between soft tissue response and the following variables: type of surgery, genioplasty, lip thickness, method of surgical site closure, interlabial distance and eversion of the lower lip. Preoperative …

Robotic Simulation of Disc Arthroplasty Surgery: Influence of Surgical Placement on Motion Segment Dynamics
… two conditions were not comparable. Transfer of tissue pretension from the implant to the Spine Robot on removal of the implant, and dynamic contact forces at the implant surfaces were the contributing factors to the differences observed.</p> <p>Simulated COR testing demonstrated that the …

Effects of Dip-coated films on the Properties of Implantable Intracortical Microelectrodes
… and paralysis is limited by a reactive tissue response (RTR) of the brain. This RTR culminates in the formation of a tight glial scar and a loss of neuronal density around implanted ICMs, and is accompanied by a decrease in signal to noise ratio and an increase in impedance. While no …

A study of nanostructured materials toward coronary artery stenting and DNA-based biosensing
… are subject to re-obstruction triggered by host tissue. A plasma nanocoating (20-30 nm) has been investigated for its ability to improve patient tissue response. Nanocoatings were deposited using low temperature non-equilibrium plasma glow discharges. Nanocoatings were further modified with …
