Fluorimetric multiparameter cell assay at the single cell level fabricated by optical tweezers. (1/328)

A fluorimetric multi-parameter cell sensor at the single cell level is presented which makes it possible to observe the physiological behavior of different cell lines, different physiological parameters, and statistical data at the same time. Different cell types were immobilized at predefined positions with high accuracy using optical tweezers and adhesion promoting surface layers. The process is applicable to both adherent and non-adherent cells. Coating of the immobilization area with mussel adhesive protein was shown to be essential for the process. Intracellular proton and calcium concentrations in different cell classes were simultaneously imaged and the specific activation of T lymphocytes was demonstrated. This method should be especially useful for drug screening due to the small sample volume and high information density.  (+info)

In vitro comparison of the retention capacity of new aesthetic brackets. (2/328)

Tensile bond strength and bond failure location were evaluated in vitro for two types of aesthetic brackets (non-silanated ceramic, polycarbonate) and one stainless steel bracket, using bovine teeth as the substrate and diacrylate resin as the adhesive. The results show that metallic bracket had the highest bond strength (13.21 N) followed by the new plastic bracket (12.01 N), which does not require the use of a primer. The non-silanated ceramic bracket produced the lowest bond strength (8.88 N). Bond failures occurred mainly between bracket and cement, although a small percentage occurred between the enamel-cement interface with the metal and plastic brackets and within the cement for the plastic bracket. With the ceramic bracket all the failures occurred at the bracket-cement interface. This suggests that the problems of enamel lesions produced by this type of bracket may have been eliminated. The results also show that the enamel/adhesive bond is stronger than the adhesive/bracket bond in this in vitro study.  (+info)

Autoclaving impairs the connector-tube bond of the laryngeal mask airway but not its airtightness. (3/328)

The general-purpose laryngeal mask airway (LMA) is re-usable when undamaged, and cleaned and autoclaved correctly. We had found weakening of the silicone adhesive that bonds the connector of the LMA to the tube. We report that repeated autoclaving damaged the adhesive such that the connector could be rotated in the tube after the 12th autoclave cycle in almost all of the LMA tested. The damage to the adhesive did not affect the airtightness of the junction, which appears to be maintained by the material properties of the connector and tube and by the shape of the join.  (+info)

A laboratory investigation to compare enamel preparation by sandblasting or acid etching prior to bracket bonding. (5/328)

A laboratory investigation to compare the mean shear debonding force and mode of bond failure of metallic brackets bonded to sandblasted and acid-etched enamel is described. The buccal surfaces of 30 extracted human premolars were sandblasted for 5 seconds with 50 mu alumina and the buccal surfaces of a further 30 human premolars were etched with 37 per cent phosphoric acid for 15 seconds. Following storage for 24 hours at 37 degrees C in distilled water, shear debonding force was measured using an Instron Universal Testing Machine with a cross-head speed of 10 mm/minute. Mean shear debonding force was significantly lower for brackets bonded to sandblasted enamel compared to acid etched enamel (P < 0.001). Weibull analysis showed that at a given stress the probability of failure was significantly greater for brackets bonded to sandblasted enamel. Brackets bonded to etched enamel showed a mixed mode of bond failure whereas following sandblasting, failure was adhesive at the enamel/composite interface (P < 0.01).  (+info)

Factors affecting the shear bond strength of orthodontic brackets to porcelain. (6/328)

The aim of this investigation was to establish a regime for orthodontic bonding to feldspathic porcelain, which ensures adequate bond strength (6-8 MPa) with minimal damage on debond and consisted of an ex vivo investigation measuring the effects of porcelain surface preparation and thermocycling on shear bond strength of orthodontic brackets. One-hundred-and-twenty feldspathic porcelain bonded crown surfaces were divided into 12 equally-sized groups to assess the effects of: (1) glaze removal, (2) application of hydrofluoric acid, phosphoric acid, or omission of acid treatment, and (3) silane priming upon the bond strength of premolar brackets bonded with Right-on (TM) composite resin adhesive. Specimens were subjected to thermocycling and then to shear debonding forces on an Instron machine. Removal of the porcelain glaze, or use of hydrofluoric acid, prior to bonding were found to be unnecessary to secure the target bond strength. Hydrofluoric acid application was associated with increased porcelain surface damage. Thermocycling caused a significant reduction in shear bond strength to porcelain (P < 0*001). The best regime for orthodontic bonding to feldspathic porcelain was to apply phosphoric acid for 60 seconds, and prime with silane prior to bonding. Usually the porcelain surfaces could be repolished. Refereed Paper  (+info)

Differentiation of mucilage secretory cells of the Arabidopsis seed coat. (7/328)

In some plant species, including Arabidopsis, fertilization induces the epidermal cells of the outer ovule integument to differentiate into a specialized seed coat cell type with a unique morphology and containing large quantities of polysaccharide mucilage (pectin). Such seed coat mucilage cells are necessary for neither viability nor germination under normal laboratory conditions. Thus, the Arabidopsis seed coat offers a unique system with which to use genetics to identify genes controlling cell morphogenesis and complex polysaccharide biosynthesis and secretion. As a first step in the application of this system, we have used microscopy to investigate the structure and differentiation of Arabidopsis seed coat mucilage cells, including cell morphogenesis and the synthesis, secretion, and extrusion of mucilage. During seed coat development in Arabidopsis, the epidermal cells of the outer ovule integument grow and differentiate into cells that produce large quantities of mucilage between the primary cell wall and plasma membrane. Concurrent with mucilage production, the cytoplasm is shaped into a column in the center of the cell. Following mucilage secretion the cytoplasmic column is surrounded by a secondary cell wall to form a structure known as the columella. Thus, differentiation of the seed coat mucilage cells involves a highly regulated series of events including growth, morphogenesis, mucilage biosynthesis and secretion, and secondary cell wall synthesis.  (+info)

1H-NMR studies of the interaction of dental adhesive monomer, 4-META with calcium. (8/328)

Our objective was to determine whether high-resolution proton-nuclear magnetic resonance (500 MHz) could be utilized for detection of ionic binding interaction of the 4-META resin system with calcium derived from hydroxyapatite. The stability of 4-META in aqueous medium was studied, findings indicated that 4-META was rapidly converted to 4-MET, a hydrate product of 4-META in 10% D2O/DMSO-d6. The 1H-NMR signals of the methacryloyloxyethoxy group of 4-MET remained intact following the addition of both monocalcium phosphate (MCP) and dicalcium phosphate dihydrate (brushite) solution, whereas those of its trimellitic portion were markedly shifted upfield depending on the phosphate concentration. The shielding effect followed by upfield shifts was due to the localization of electron density surrounding the carboxylate anions that were dissociated by the interaction with calcium counter cation. The shielding effect of 4-MET with brushite was larger than that with MCP. An ionic interaction of 4-MET derived from 4-META with calcium was demonstrated.  (+info)

0010] Inventors of the present invention conducted intensive studies on an inorganic filler and a resin composition in order to provide an adhesive material having sufficient adhesiveness and sufficient heat resistance. As a result, the inventors found that a layered clay mineral dispersed in an adhesive agent does not undergo complete interlayer separation, but the layered clay mineral is dispersed in the adhesive agent with its layers being in a stacked state. Therefore, the resulting adhesive composition suffers from variations in physical properties. Further, the inventors found that, where an adhesive tape is produced by using the adhesive composition, stress is liable to be concentrated on peripheries of particles of the layered clay mineral in the adhesive agent during peel-off of the adhesive tape, resulting in cohesive failure of the adhesive agent. As a result of further studies, the inventors found that, where an organophilic layered double hydroxide (B) organically treated with an ...

Pressure-sensitive adhesives (PSAs) have become more popular in demanding tape and label applications. Many high-performance PSA applications are dominated by solvent acrylic PSAs and radiation-curable PSAs because they can achieve much higher cohesive strength and heat resistance than other technologies, including typical emulsion PSAs. Due to these performance limitations, waterborne emulsion PSAs are used in less demanding applications.

Complex coacervation of two oppositely charged polysaccharides, namely a lactose-modified chitosan (CTL) and hyaluronan (HA), was investigated in this study. Coacervates of the two polysaccharides were prepared by drop-by-drop injection of HA into CTL. Transmittance and dynamic light scattering (DLS) measurements in combination with TEM analyses demonstrated the formation of spheroidal colloids in the nano-/microsize range showing good homogeneity. Strikingly, the presence of 150 mM supporting NaCl did not hamper the colloid formation. Stability studies on selected formulations demonstrated that HA/CTL coacervates were stable up to 3 weeks at 37 °C and behaved as pH-responsive colloids since transition from entangled to disentangled chains was attained for a proper pH range. The possibility of freeze-drying the coacervates for storage purposes and the ability of encapsulating selected payloads were investigated as well, for two values of the fraction of the lactitol side-chain substitution ...

Preferably the beta-lactoglobulin and the anionic polymers are essentially free of salts ( Preferably the anionic polymer comprises a caseinate or a casein derivative. Encapsulates comprising beta-lactoglobulin and caseinate according to the invention are highly susceptible towards the proteolytic activity as observed in the human stomach. Therefore their disintegration and release of the content occurs earlier as from encapsulates based on modified gelatin (crosslinked). Gelatin is known to be more resistant against the proteolytic activity of the stomach by pepsin but not against the duodenal proteases. This time difference in release between gelatin and non-gelatin encapsulates results in a faster dissolution of the encapsulated agents in the stomach contents from the non-gelatin product, resulting in a better bioavailability for compounds for which dissolution is the rate-limiting step in the bioavailability ...

Should a universal adhesive be used with a self- or dual-cured buildup or cement?. Although universal adhesives are typically on the higher end of the pH spectrum of self-etching adhesives, they are still relatively acidic (Figure 2). A common problem of any one-step self-etching adhesive is they will leave an acidic surface following application to tooth structure. This acidic surface will interfere with the amine-based chemical reaction used to cure self-cured or dual-cured resins.17 In other words, application of an acidic universal adhesive to tooth structure can prevent curing of a self-cured resin cement or buildup material placed on top of it. In some cases, this may cause debonding of a buildup, post or fixed restoration.. There are two methods to avoid this possible failure. The first is to use a dual-cure activator with the universal adhesive. This activator is typically sold with the universal adhesive and can be mixed in a 1:1 ratio with the adhesive. It contains arylsulfinate salts ...

In the past several decades the problem of longevity and durability of adhesive interfaces between hard tooth tissues and composite resin-based materials are of great interest among dental researchers and clinicians. These parameters are partially determined by adhesive system mechanical properties. In the present research project nanoindentation has been examined to test hardness of dental adhesive systems. A series of laboratory experiments was performed to study the effect of light curing time and oxygen inhibition phenomenon on light-cured adhesive material hardness. An adhesive system AdperTM Single Bond (3M ESPE) was selected as a material for testing. The analysis of experimental data revealed that the maximum values of hardness were observed after the material had been light-cured for 20 seconds, as outlined in guidelines for polymerization time of the adhesive system.

Thermosetting systems, unlike thermoplastics, form permanent, heat-resistant, insoluble bonds that cannot be modified without degradation. Adhesives based on thermosetting polymers are widely used in the aerospace industry. Thermosets include phenol formaldehyde, urea formaldehyde, unsaturated polyesters, epoxies, and polyurethanes. Elastomer-based adhesives can function as either thermoplastic or thermosetting types, depending on whether cross-linking is necessary for the adhesive to perform its function. An important challenge facing adhesive manufacturers and users is the replacement of adhesive systems based on organic solvents with systems based on water. This trend has been driven by restrictions on the use of volatile organic compounds (VOC), which include solvents that are released into the atmosphere and contribute to the depletion of ozone. In response to environmental regulation, adhesives based on aqueous emulsions and dispersions are being developed, and solvent-based adhesives are ...
Cells are composed of collections of highly complex but tightly regulated reaction networks that are well organized both in space and in time. Spatial organization can be achieved through localization of molecules and reactions at surfaces and in compartments.1,2 Besides membrane-encapsulated organelles, cells are known to form different types of membraneless organelles with varying compositions.2-4 Examples include germ granules,5,6 processing bodies,7,8 stress granules9,10 and nucleoli.11-13 Increasing evidence indicates that most of these compartments can be classified as coacervates:14,15 they are liquid droplets that are enriched in macromolecules and are formed by a liquid-liquid phase separation.3,14-21 The liquid-like nature and absence of an encapsulating membrane give rise to a direct link with processes taking place in the cytoplasm or nucleoplasm,3 providing for functions such as sequestration, buffering and reaction rate modulation.2 Like in many synthetic model systems that exhibit ...

Objectives: Evaluate the performance of two self-etching adhesives clinically. Methods: Eighty-four Class V restorations were placed in 21 patients in need of 2, 4 or 6 restorations in incisors, canines and premolars. The retention relied only on the adhesive (no mechanical retention). The two evaluated adhesives were iBond NG plus B(IBSE)(Heraeus Kulzer GmbH) and Clearfil SE (CLSE)(Kuraray), and the composite was Venus (Heraeus Kulzer GmbH). One week after placement, the patients were recalled for baseline evaluation. Following the baseline evaluation, the patients were recalled and evaluated after 3 months, 1 year, 2 years and 4 years using similar evaluations. Results: At the 4-year evaluation, 4 patients did not show up for evaluation. The remaining 17 patients had originally received 66 restorations (33 of each adhesive). Of these restorations, 8 had been lost during the 4 years (4 IBSE and 4 CLSE). A noticeable finding was that two of the restorations (1 IBSE and 1 CLSE) had failed in the ...

Film adhesives have great application potential in high-tech areas like aerospace. Bonding is the technique employed in the manufacture of several critical structure components for aerospace applications. Notable components include, honeycomb structures, antennas, solar sail and solar panel for satellites. Solar sail is made by bonding polyimide film segments. A polyimide suitable for such applications is marketed by DuPont in the trade name KAPTON. The bonding requirements in majority of these areas ar e generally met by use of glue-1ike and solvent-based resinous polymeric adhesives. There is an increased preference for dry film adhesives for such applications. This is because use of film adhesive can faci1itate bonding manoeuvre, avoid use of solvents and help regulate the flue line thickness and minimise wastage of adhesive and accumulation of dead weight which are very critical when weight saving becomes a matter of concern. A few film adhesives for structural and general purpose ...

The second experiment will attempt to prove that if space is provided and homogeneous cell interactions are preferred, that a cluster of cells with different adhesive affinities will relocate in order to achieve separate homogeneous clusters. This experiment will test the hypothesis that the cluster of cells with the higher adhesive affinity will migrate away from the cluster of cells with the lower adhesive affinity. This experiment could be performed by creating a cell adhesion affinity gradient sample in vitro, containing clusters of cells ranging from a low adhesive affinity to a high adhesive affinity. The clusters of cells would be arranged progressing from low affinity to high affinity. Then, an external cluster of high adhesive affinity cells would be added to an area of the gradient which contains a lower adhesive affinity. I expect that the cluster of high adhesion affinity cells would migrate until it reached a place where the gradient is greater on one side and lower on the other ...
