The American Academy of Dermatology and the American Society of Plastic Surgeons, with the support of other sister societies, conducted the Facial Soft-Tissue Fillers: Assessing the State of the Science conference in December of 2009. The American Academy of Dermatology and the American Society of Plastic Surgeons established a panel of leading experts in the field of soft-tissue fillers-from r...
Our paper reviews the use of conductive polymer composite materials in various applications for semi conductive, static-dissipative, anti-corrosive, electromagnetic interference (EMI) shielding and stealth composite coatings. The composite consists of conductive fillers and the insulating polymer network. The composite becomes electrically conductive as the filler content exceeds a certain crit...
BACKGROUND A variety of hyaluronic acid (HA) fillers demonstrate unique physical characteristics, which affect the quality of the HA filler products. The critical factors that affect the degradation of HA gels have not yet been determined. OBJECTIVE Our objective was to determine the characteristics of HA gels that affect their resistance to the degradation caused by radicals and enzymes. M...
Edible films and coatings in foods can be used to increase shelf-life and improve organoleptic characteristics of foods by avoiding deterioration of food components and therefore promoting preservation of the final product. This study is the first to investigate the use of different size fillers for the purpose of preparing edible composite films with fillers < 1.0 microm in size. For this purp...
BACKGROUND Hyaluronic acid (HA) formulations are used for aesthetic applications. Different cross-linking technologies result in HA dermal fillers with specific characteristic visco-elastic properties. OBJECTIVE Bio-integration of three CE-marked HA dermal fillers, a cohesive (monophasic) polydensified, a cohesive (monophasic) monodensified and a non-cohesive (biphasic) filler, was analysed w...
ZnO particles of different size and structures were used as fillers to modify the silicone rubber, in order to reveal the effect of the filler shape in the polymer composites. Tetrapodal shaped microparticles, short microfibers/whiskers, and nanosized spherical particles from ZnO have been used as fillers to fabricate the different ZnO-Silicone composites. The detailed microstructures of the fi...
Time affects facial aging by producing cellular and anatomical changes resulting in the consequential loss of soft tissue volume. With the advent of new technologies, the physician has the opportunity of addressing these changes with the utilization of dermal fillers. Hyaluronic acid (HA) dermal fillers are the most popular, non-permanent injectable materials available to physicians today for t...
BACKGROUND Hyaluronic acid (HA) fillers are becoming the material of choice for use in cosmetic soft tissue and dermal correction. HA fillers appear to be similar, but their physical characteristics can be quite different. These differences have the potential to affect the ability of the physician to provide the patient with a natural and enduring result. OBJECTIVE The objective of this artic...
A plethora of soft tissue fillers have been developed within the past decade to correct the cutaneous changes that occur with photoaging. Such fillers, whether nonpermanent, semipermanent, or permanent, are widely used to fill undesired facial rhytides. In addition, fillers are employed to correct atrophy of the face as well as other parts of the body such as the dorsum of the hands through vol...
Hyaluronic acid (HA) is a linear naturally occurring polysaccharide formed from repeating disaccharide units of N-acetyl-D-glucosamine and D-glucuronate. HA is omnipresent in the human body but highest amounts are found in soft connective tissues. HA is involved in several key processes, including wound repair, regeneration, and matrix organization. To increase stability, modifications of HA li...
