Clinics in Plastic Surgery, 1996
Alloplastic materials have become an essential part of reconstructing the craniofacial skeleton. This article reviews several of the more commonly used implant materials and summarizes their mechanical properties and use in reconstructive surgery.

Metaplasticity: the plasticity of synaptic plasticity
Trends in Neurosciences, 1996In this paper, we review experimental evidence for a novel form of persistent synaptic plasticity we call metaplasticity. Metaplasticity is induced by synaptic or cellular activity, but it is not necessarily expressed as a change in the efficacy of normal synaptic transmission.

Plastics, Plasticity, and the Plastic
Interdisciplinary Literary StudiesABSTRACT This article examines the development of the idea of “plasticity” by proposing two critical moments in its conceptual epigenesis: that of plastics, represented by Cudworth and Shaftesbury in the seventeenth century, and that of plasticity as elaborated by Catherine Malabou in the twenty-first century.

2013
A variety of noninvasive brain stimulation techniques have been used to study neuronal plasticity. Mostly, noninvasive techniques have been employed, and the bulk of studies have focused on the motor system, because its physiology is more readily accessible and physiological properties can be studied with greater detail than in other systems.

Nature, 1997
The connections between neurons (synapses) can adapt to changing circumstances of nervous transmissions, a phenomenon known as activity-dependent plasticity. Moreover, such plasticity is itself regulated, but little is known about the mechanisms or behavioural consequences of this metaplasticity.

A QSPR for the plasticization efficiency of polyvinylchloride plasticizers
Journal of Molecular Graphics and Modelling, 2008A simple quantitative structure property relationship (QSPR) for correlating the plasticization efficiency of 25 polyvinylchloride (PVC) plasticizers was obtained using molecular modeling. The plasticizers studied were-aromatic esters (phthalate, terephthalate, benzoate, trimellitate), aliphatic esters (adipate, sebacate, azelate), citrates and a ...

Plasticizers in Rubbers and Plastics
Rubber Chemistry and Technology, 1947Abstract Up to the advent of synthetic high polymers, plasticizer technology was little understood, Plasticizers had been used mainly with cellulose derivatives, which are not at all good materials for the study of plasticizer action. The chemical processing they undergo, e.g., nitration, acetylation, etc., leads to variations on account of ...

Paying and playing with plastic. The meaning of plastics, plasticity, and plastic surgery.
Medical device technology, 1997Plastics are not only the proverbial everyday commodity, but they also permeate almost every aspect of medical devices, from technology to clinical application. This article addresses some of the confusing features of plasticity as they relate to the materials called plastics, to the phenomena of material plasticity, and to the clinical and biological ...
