✦ Synopsis

Using the Hellman and Hillert model for the shape of a deformed boundary, the Zener drag originated by a spherical particle is analyzed. An expression for the pinning stress is obtained and it is compared with the original finding of Zener and with some recent results from the literature. Rbnm&-Nous analysons le trainage de Zener dti a une particule sphcrique a l'aide du modile de Hellman et de Hillert pour la forme d'un joint deform& Nous obtenons une expression de la contrainte d'ancrage que nous comparons avec les travaux originaux de Zener et avec quelques resultats r&cemment publics. Zusammenfassung-Mit dem Model1 fur die Form einer gekriimmten Korngrenze von Hellman und Hillert wird die von einem spharischen Teilchen herrilhrende Zoner-Reibungspannung analysiert. Es wird ein Ausdruck erhalten, der mit dem von Zener ursprilnglich erhaltenen und einigen neueren Ergebnissen aus der Literatur verglichen wird.

## Abstract This study was conducted to test the hypothesis that growth factors can reduce the suppressive effect of titanium particles on MSCs. Cultured human MSCs at passage 3 were challenged with prepared cpTi particles at a concentration of 500 particles/cell along with one of the following gro

## Abstract In this study, a novel nonviral gene delivery system, which could enhance the inhibition effect of antisense oligonucleotides (ASODN) against the tumor cells, was developed. The polycation liposomes (PCLs) were prepared using the film hydration method with dioleoylphosphatidylethanolami
