Facial fillers play an important role in the correction of facial changes associated with ageing. They offer quick treatments in the outpatient setting with minimal subsequent downtime that provide predictable, natural-looking, long-lasting results. Hyaluronic acid soft tissue injectables have established their role as the fillers of choice for patients over the last 2 decades. Hyaluronic acid fillers are rarely associated with adverse reactions, and those that do occur tend to be mild and temporary. However, as with all injected or implanted biomaterials, adverse events can occur and patients must be fully informed of potential risks prior to undergoing treatment...

Given the short recovery and immediate results, facial fillers have become a popular alternative to surgical rejuvenation of the face. Reported complications arising from facial filler injections include erythema, tissue loss, blindness, stroke, and even death. In this article, the authors describe their anatomically based techniques to minimize risk and maximize safety when injecting in the facial danger zones, including the glabella/brow, temporal region, perioral region, nasolabial fold, nose, and infraorbital region...

Texture modifying abilities of whey protein microparticles are expected to be dependent on pH during heat-induced aggregation of whey protein in the microparticulation process. Therefore, whey protein microparticles were prepared at either pH 5.5 or 6.8 and their effects on small and large deformation properties of gellan gels containing whey protein microparticles as fillers were investigated. The majority of whey protein microparticles had diameters around 2 μm. Atomic force microscopy images showed that whey protein microparticles prepared at pH 6...

The USA Food and Drug Administration (FDA) established benzo[a]pyrene (B[a]P) as a harmful and potentially harmful constituent (HPHC) found in tobacco products. Tobacco manufacturers are required to report HPHC quantities to the FDA; however, there is currently no standardized method for determination of B[a]P in smokeless tobacco products (STPs). This work details a sensitive, selective and rapid method for the determination of B[a]P in STPs, cigarette filler and tobacco. Tobacco is extracted using methanol followed by solid-phase extraction and concentration prior to analysis by gas chromatography/mass spectrometry in the selected ion monitoring mode...

OBJECTIVE: To evaluate the effect of silica dioxide (SiO2) nanofillers in different bonding systems on shear bond strength (SBS) and mode of failure of orthodontic brackets at two experimental times. METHODS: Ninety-six intact premolars were divided into four groups: A) Conventional acid-etch and primer Transbond XT; B) Transbond Plus self-etch primer; and two self-etch bonding systems reinforced with silica dioxide nanofiller at different concentrations: C) Futurabond DC at 1%; D) Optibond All-in-One at 7%...

The reuse of waste is increasingly widespread in order to avoid the exploitation of natural resources and to reduce costs. An example of that reuse is the employment of steel slag, a by-product from the steel making process. When the steel is produced through an electric arc furnace (EAF), two types of slag are generated: black and white slag. One application rarely used for this waste is as filler in forest tracks. In this work, two forest tracks of the Basque Country (northern Spain) filled with black and white slag 19 and 35years ago, respectively, have been studied...

Mycophenolic acid (MPA), the active compound of mycophenolate mofetil (MMF), is widely used as an antirejection drug following renal transplantation. There is growing evidence supporting the notion that there is substantial variability in the intra- and inter-patient exposure to MPA. Drug interactions involving MPA with tacrolimus, steroids, and sirolimus have been understudied. The objective of this study was to determine the relationship between MPA, steroids, tacrolimus, and sirolimus. MPA trough concentrations from 37 pediatric renal transplant recipients (mean age 7...

There have been many investigations on non-biodegradable materials acting as an antibiotic carrier for local drug delivery systems based on polymethyl methacrylate (PMMA) beads. However, the material is non-degradable and non-porous so that less than 5% of the encapsulated drug is released. In order to obtain better release of the antibiotics, greater porosity of the beads would be required. Adding fillers could increase the bead's porosity, thus improving the antibiotic release from the beads. The purpose of the study is to optimize release kinetics of gentamicin from handmade beads by adding fillers such as glycine and sodium chloride in different concentrations...

BACKGROUND: Blindness caused by soft tissue fillers is an extremely low-probability event, but it results in great concern because of its devastating consequences. Currently, the mechanism of an embolism is usually considered to be an accidental injection of fillers into the blood vessels of the face, such as a facial artery, and then retrograding into the ophthalmic artery system, which causes retinal ischemic necrosis. In addition, previous studies have shown that there are anastomoses between facial arteries and branches of the ophthalmic artery in cadavers...

BACKGROUND: Different methods have been used to prepare bone-like composites from inorganic nanoparticles embedded in polymeric matrixes to obtain the properties and structures required for bone fillers. METHODS: Bone-like nano-hydroxyapatite (nHA) was synthesized using a biomimetic method, with polyvinylpyrrolidone (PVP) as template and sodium dodecyl sulfate (SDS) as surfactant. RESULTS: The results demonstrated the formation of HA composites and showed that polymer and surfactant as the polymer capsule can be properly used to control the size, shape, morphology and dispersion of HA crystals...

The present paper describes the result of investigations into preparation of novel nanocomposites (NCs) based on poly(N-vinyl-2-pyrrolidone) (PVP) as a biocompatible polymer and modified copper (II) oxide nanoparticles (NPs) as a nano-filler. To achieve optimum NCs properties, different ratios of modified copper (II) oxide NPs (3, 5, and 7wt%) were used to fabricate PVP NCs and also the ultrasonic irradiation was utilized to perform these processes as a fast and effective method. Subsequently, the structure of the obtained nanohybrids was characterized by various techniques...

Using an emulsion road and optimizing the dispersion process, we prepare polymer carbone nanotubes (CNT) and polymer reduced graphene oxyde (rGO) composites. The introduction of conductive nanoparticles into polymer matrices modifies the electronic properties of the material. We show that these materials exhibit giant electrostriction coefficient in the intermediate filler concentration (below 1wt %). This makes them very promising for applications including such as capacitive sensors and actuators. In addition, the values of the piezoresistivity measured in the high filler concentration situation, are at least an order of magnitude greater than the one reported in the literature...

Polylactic acid (PLA) fillers are widely used for cosmetic volume augmentation. But, no study has evaluated the use of PLA filler in penile augmentation (PA No. 4). We evaluated the efficacy and safety of a newly developed PLA filler for PA during a 18-month follow-up period. A total of 23 healthy adult men were prospectively enrolled between June and November 2012. Penile girth was measured at proximal-, mid- and distal-shaft at baseline, 3, 6, 12 and 18 months following injection. Subjects' satisfaction was assessed with visual analogue scale (VAS)...

The aim of this study is to investigate the effect of particles as filler in soft rubber sensors installed in artificial skin. We examine sensors made of natural rubber (NR-latex) that include magnetic particles of Ni and Fe₃O₄ using magnetic compound fluid (MCF). The 1-mm thickness of the electrolytically polymerized MCF rubber makes production of comparatively thin rubber sensors feasible. We first investigate the effect of magnetic particles Ni and Fe₃O₄ on the curing of MCF rubber. Next, in order to adjust the electric properties of the MCF rubber, we adopt Al₂O₃ dielectric particles...

Importance: The effects of rhinoplasty maneuvers on adjacent facial features are an important component in preoperative planning and patient counseling. Tip projection modifications are commonly performed in both cosmetic and reconstructive rhinoplasty. Objective: To evaluate the subsequent change in lip projection that results from increasing nasal tip projection. Design, Setting, and Participants: In this case series, 20 patients underwent primary rhinoplasty with the objective of increasing tip projection during the period from October 1, 2014, to September 25, 2015...
