Bioactive glass is used as both a bone filler and as a coating on implants, and has been advocated as a potential osteogenic scaffold for tissue engineering. Rat-derived mesenchymal stem cells (MSCs) show elevated levels of alkaline phosphatase activity when grown on 45S5 bioactive glass as compared to standard tissue culture plastic. Similarly, exposure to the dissolution products of 45S5 elev...

The polymer-filler interaction of a dental composite was examined by dielectric measurements to determine how a non-compatible inorganic phase modifies the molecular behaviour of the polymer chains and how modification of this phase by silanation can affect these molecular behaviours. Urethane dimethacrylate (UDMA) monomer and zirconia-silica (ZS) powder were used as organic and inorganic phase...

INTRODUCTION Polyacrylamide hydrogel has been considered a safe and biocompatible soft tissue filler, and it has been widely used in cosmetic procedures. However, recent studies have revealed some complications with polyacrylamide filler injections. CASE REPORT We present the case of foreign-body granulomas of the glabella, which subsequently formed an infectious ulcer 3 years after a polyacr...

The combined use of a highly magnetic filler (mumetal) in low proportion and a highly conductive filler in high proportion in a polymer matrix provides a composite material that is more effective for electromagnetic interference shielding than the use of a highly magnetic filler alone or the use of a highly conductive filler alone. Mumetal is effective (due to absorption) when it is in a compos...

In this paper, I argue that the retrieval of filler-phrases in syntactic filler-gap dependencies is facilitated by encoding more information in the filler-phrase. Three self-paced reading experiments provide the evidence for this memory facilitation hypothesis: reading times decrease when more explicit whphrases and indefinites occur as fillers in three different syntactic constructions. Crucia...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Effect of TiO2 and ZrO2 filler on mechanical properties of the epoxy polymer has been investigated experimentally. TiO2 and ZrO2 filler epoxy composites are fabricated by hand layup technique in a mold and cured under light pressure at room tempera...

Filled pauses are ubiquitous in everyday speech. I investigated whether linguistic complexity of upcoming phrases affects filler rate at phrase boundaries in presentation speeches in Japanese. Filler rate at phrase boundaries increased monotonically with complexity of the following phrases. However, when the following phrase was composed of more than 11 Bunsetsu-phrases, the filler rate did not...

The nose is one of the most important cosmetic units of the face. Discreet variations in the nose shape lead to marked physiognomy changes. Many patients dissatisfied with the appearance of their nose seek cosmetic improvement as early as during adolescence. Similar to other facial structures, the nose is affected by the aging process. Typically, nose tip drop is observed, along with loss of su...

Restoring volume in the middle and lower portions of the face is becoming an indispensable component of modern facial rejuvenation. Radiesse (BioForm Medical, San Mateo, Calif.) is an injectable filler material composed of synthetic calcium hydroxylapatite microspheres (30 percent) suspended in an aqueous carrier gel (70 percent). At present, Radiesse is indicated in the United States for corre...

In this paper, the electromagnetic shielding characteristics of an up-to-date typical carbon filler material, carbon fiber used with a metal mesh were investigated. Carbon fiber 12k-prepregs, where carbon fibers were impregnated with epoxy, were laminated with wire meshes, vacuum bag-molded and hardened to manufacture hybrid-type specimens, with which an electromagnetic shield test was performe...
