Soft tissues exhibit a nonlinear, essentially incompressible (visco-) elastic response; a key issue is the active nature of muscle fibres, in other words their ability to contract and relax in response to biochemical signals. Here we present a continuum model able to describe an active elastic medium.

The present study investigated the effects of microinjections of acetylcholine (a cholinergic agonist), physostigmine (a cholinesterase inhibitor), atropine (an antagonist of muscarinic cholinergic receptors) and hexamethonium (an antagonist of nicotinic cholinergic receptors) into the parafascicular nucleus of thalamus on the acute corneal nociception in rats. Acute corneal nociception was ind...

purpose: to evaluate the effect of topical phenytoin 1 % on corneal epithelial defects healing in a rabbit model. methods: one eye of 20 albino rabbits in the animal house of al-zahra ophthalmology hospital was studied. a single corneal epithelial defect was created. the rabbits were randomly assigned into two groups (ten animals in each group). after creating a chemical burn in rabbits, one gr...

The purpose of this study is to investigate the visco-elasticity, histology and hydrodynamics of transplanted menisci following transplantation. Experiments to examine visco-elasticity are performed on 30 rabbits, to examine NMR on 20 rabbits and on 12 rabbits respectively for histological study. Under intravenous general anesthesia the medial meniscus was completely resected, and a cryopreserv...

We demonstrate refinements of a simple elastic-viscous-plastic rheological model with the addition thixotropic term to better flow human blood. The alteration this will contribute representation lightly structured complex materials. (EVP) framework requires thixotropy for more accuracy in fitting and predicting thixo-elasto-visco-plasticity flows microstructure. performance added features by co...
