Drug delivery in biological tissues: an application to the eluting stents
No full textThe drug diffusion process through an arterial eluting stent is studied with a mathematical model. An exact analytical solution is given in the form of an infinite series expansion. The model addresses the role of four controlling parameters and provides qualitative considerations and a quantitative description for drug transport to evaluate feasibility of new drug delivery strategies, and to estimate dose response
Mass transfer phenomena. A case study: drug-eluting stents.
No full textA stent is a small mesh tube that is inserted permanently into a stenotic artery. The stent
restores the original value of the arterial section to ensure the physiological flow rate.
One of the problems caused by stent insertion is re-narrowing of the treated vessel.
To overcome this phenomenon drug-eluting stents (DES)
have been recently introduced. Referred to as a coated ormedicated stent, a DES is a normal
metal stent that has been coated with a pharmacologic agent (drug) that is known to interfere
with the process of restenosis (reblocking).
However, the design of such devices is a very complex task because
their performance in widening the arterial lumen and preventing further restenosis
is influenced by many factors such as the geometrical design of the stent,
the mechanical properties of the materials and the chemical properties of the drug that is released.
Mathematical models and numerical simulation techniques are appropriate to study such phenomena
with the aim to be used as a predictive tool for the effective design of drug eluting stents.
We present in this section a brief review fluid dynamics and drug release models
developed by the authors for the numerical simulation of drug eluting coronary stents

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
