The aim of this study was to evaluate the degradation of completely demineralized dentin specimens in contact with a filler-free or 2 ion-releasing resins containing micrometer-sized particles of Bioglass 45S5 (BAG) or fluoride-containing phosphate-rich bioactive glass (BAG-F). Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were also used to evaluate the remineralization induced by the experimental ion-releasing resin-based materials. Dentin beams were totally demineralized in H3PO4 (10%) and placed in direct contact with a filler-free (RESIN) or 2 experimental ion-releasing resins (BAG or BAG-F) and immersed in artificial saliva (AS) up to 30 d...

BACKGROUND: Many parallels exist between growth and development of the placenta and that of cancer. One parallel is shared expression of antigens that may have functional importance and may be recognized by the immune system. Here, we characterize expression and regulation of one such antigen, Trophoblast glycoprotein (TPGB; also called 5T4), in the placenta across gestation, in placentas of preeclamptic (PE) pregnancies, and in purified microvesicles and exosomes. METHODS: Trophoblast glycoprotein expression was analyzed by real-time reverse transcription-polymerase chain reaction (RT-PCR), Western blot, and immunohistochemistry...

The objectives of this study were (1) to assess the effect of a denatured whey protein concentrate (DWPC) and its fractions on cheese yield, composition, and rheological properties, and (2) to separate the direct effect of the DWPC or its fractions on cheese rheological properties from the effect of a concomitant increase in cheese moisture. Semihard cheeses were produced at a laboratory scale, and mechanical properties were characterized by dynamic rheometry. Centrifugation was used to induce a moisture gradient in cheese to separate the direct contribution of the DWPC from the contribution of moisture to cheese mechanical properties...

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...

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...

H N Rasyid, S Soegijoko
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...

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 performance of elastomeric materials, i.e. in car tires, is substantially determined by the used reinforcing filler system. In particular, the flocculation tendency of filler particles to form clusters and even network-like structures significantly determines the mechanical properties of these elastomer materials and enhances especially their energy dissipation under periodic mechanical deformations. In a simplified thermodynamic model, inspired by a segregation model from game theory, we describe fundamental mechanisms of filler structure formation...

The three-dimensional visualization model of human body duct is based on virtual anatomical structure reconstruction with duct angiography, which realizes virtual model transferred from two-dimensional, planar and static images into three-dimensional, stereoscopic and dynamic ones repectively. In recent years, the multi-duct segmentation and division of the same specimen (or organ) is the focus of attention shared by surgeons and clinical anatomists. On the basis of 4.22 g/cm(3) body bone density, this study has screened out metal oxide contract agent with different density for infusion and modeling, as well as compared and analyzed the effects of three-dimensional image of CT virtual bronchoscopy (CTVB), three-dimensional image of CT maximum intensity projection and three-dimensional model...

Porous conduits provide a protected pathway for nerve regeneration, while still allowing exchange of nutrients and wastes. However, pore sizes >30 µm may permit fibrous tissue infiltration into the conduit, which may impede axonal regeneration. Coating the conduit with Fibrin Glue (FG) is one option for controlling the conduit's porosity. FG is extensively used in clinical peripheral nerve repair, as a tissue sealant, filler and drug-delivery matrix. Here, we compared the performance of FG to an alternative, hyaluronic acid (HA) as a coating for porous conduits, using uncoated porous conduits and reverse autografts as control groups...

An all solid-state lithium-ion battery with high energy density and high safety is a promising solution for a next-generation energy storage system. High interface resistance of the electrodes and poor ion conductivity of solid-state electrolytes are two main challenges for solid-state batteries, which require operation at elevated temperatures of 60-90 °C. Herein, we report the facile synthesis of Al(3+)/Nb(5+) codoped cubic Li7La3Zr2O12 (LLZO) nanoparticles and LLZO nanoparticle-decorated porous carbon foam (LLZO@C) by the one-step Pechini sol-gel method...

A biofilter with fungus was developed for efficient degradation of benzene, which can overcome the potential risk of leakage commonly found in such services. Results indicated that the optimum parameter values were temperature 40 °C, pH 6, and 500 mg L(-1) of the initial benzene concentration. Besides, the empty bed residence time and inlet load range of biofilter were set to 20 s and 21.23-169.84 g m(-3) h(-1) respectively. Under these conditions, this biofilter can obtain the maximum removal efficiency of more than 90%, the eliminating capacity could be up to 151...

Calcium phosphate cements (CPCs) are biocompatible, resorbable, injectable and osteoconductive. Those properties render such materials suitable for applications where bone repair and regeneration is required However, their brittle nature limits their application only to non-load-bearing applications. The incorporation of long polymeric fibers can improve the mechanical properties of CPCs, but aggregation is a major problem. Instead, short polymeric fillers can be easily dispersed in the cement matrix, but their reinforcing effect has not been studied yet...

Oropharyngeal candidiasis (OPC), caused predominantly by Candida albicans, is a prevalent infection in patients with advanced AIDS, defects in Th17 immunity, and head and neck cancer. A characteristic feature of OPC is fungal invasion of the oral epithelial cells. One mechanism by which C. albicans hyphae can invade oral epithelial cells is by expressing the Als3 and Ssa1 invasins that interact with the epidermal growth factor receptor (EGFR) on epithelial cells and stimulate endocytosis of the organism. However, the signaling pathways that function downstream of EGFR and mediate C...

The general aim of this study is the recovery of Automotive Shredder Residue (ASR). The ASR light fraction, or car fluff, that was collected at an Italian shredding plant was pyrolysed at various temperatures (500-800°C) in a lab-scale reactor. The condensable gases (tar) and solid residue yields increased with decreasing temperature, and these products were characterized to suggest a potential use to reclaim them. The higher heating value (HHV) of tar was 34-37MJ/kg, which is comparable with those of fossil fuels...
