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 ...

TY - JOUR. T1 - Permeability of dentin to adhesive agents. AU - Pashley, David Henry. AU - Ciucchi, Bernard. AU - Sano, Hidehiko. AU - Homer, Jack A.. PY - 1993/1/1. Y1 - 1993/1/1. N2 - The permeability of dentin to adhesive agents is of crucial importarice in ohiaining good dentinal bonding. In those systems that remove the smear layer, the opportunity exists for resin to infiltrare both tubules and intertubular dentin. Resin penetration into tubules can effectively seal the tubules and can contribute to bond strength if the resin bonds to the tubule wall. Resin infiltration into intertubular dentin can only occur if the mineral phase ofdetitin is removed by acidic conditioners or chelators. This is more easily accomplished in fractured dentin than in smear layer-covered dentin because oJ the residual collagen debris that remains on the surface following acid etching of smear layers. The channels for resin infiltration are the perifibrillar spaces created around the collagen fibers of dentin ...

ABSTRACT: Underwater adhesives have drawn much attention in the areas of industrial and biomedical fields. However, it is still demanding to construct a tough underwater gel-based adhesive completely based on chemical constitution. Herein, a nonswellable and high-strength underwater adhesive gel is successfully fabricated through the random copolymerization of acrylic acid, butyl acrylate, and acrylated adenine in dimethyl sulfoxide (DMSO). The underwater adhesive behavior is skillfully regulated through hydrophobic aggregation induced by water?DMSO solvent exchange. The adhesive gels exhibit an excellent adhesive behavior for polytetrafluoroethylene, plastics, metals, rubber, and glasses in air and various aqueous solutions, including deionized water, seawater, and acid and alkali solutions (pH = 3 and 10, respectively). Moreover, the adhesive gels exhibited robust mechanical performance and remarkable nonswellable behavior, which were particularly important for applications of gel-based ...

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 ...

Conductive adhesives are widely used in electronic packaging applications such as die attachment and solderless interconnections, component repair, display interconnections, and heat dissipation. The effects of film thickness as functions of filler volume fraction, conductive filler size, shape, as well as uncured adhesive matrix viscosity on the electrical conduction behavior of epoxy-based adhesives are presented in this work. For this purpose, epoxy-based adhesives were prepared using conductive fillers of different size, shape, and types, including Ni powder, flakes, and filaments, Ag powder, and Cu powder. The filaments were 20 μm in diameter, and 160 or 260 μm in length. HCl and H3PO4 acid solutions were used to etch and remove the surface oxide layers from the fillers. The plane resistance of filled adhesive films was measured using the four-point method. In all cases of conductive filler addition, the planar resistivity levels for the composite adhesive films increased when the film thickness

Marine polychaetes in the family Sabellariidae live in tubular shells cobbled together with sandgrains, the broken skeletons of marine invertebrates and a protein-based underwater glue. Juvenile worms build new tubes adjoining existing tubes of the same species to create reef-like intertidal and subtidal colonies. Phragmatopoma californica (Fewkes), known commonly as the sandcastle worm, is found along the west coast of the USA. The description of a P. californica colony from the original classification by Fewkes (Fewkes, 1889) provides a sense of the turbulent habitats preferentially inhabited by sabellariids. To paraphrase, the aggregation was a continuous mass, several feet across and 1-2 feet thick, encrusted onto the roof of a cavern carved by the sea into soft rock cliffs near Santa Barbara, CA, USA. The colony was exposed for several hours between tides. Colonization of high-energy shoreside environments, such as that described by Fewkes, requires robust construction of the ...

Denture adhesives (like Polident or Steradent) should be completely cleaned off from the denture and the gums on a daily basis.. Extended use of denture adhesives (like Polident or Steradent) should not be considered without periodic assessment of your denture quality and health of the gums by your dentist.. If you find you need to use increased amounts of adhesives (like Polident or Steradent) to achieve the same level of denture fit, you should see your dentist again to evaluate the fit of the dentures.. Please come for your annual need annual check-ups - your dentist needs to examine your mouth and your dentures each year to check for health of the gums and oral health..

p, It is well known that complex coacervates can be prepared by combining aqueous solutions of oppositely charged biopolymers, such as gelatin and gum arabic. There are few examples of synthetic polyelectrolytes that produce complex coacervates, however. Two series of anionic copolymers capable of forming complex coacervates with branched polyethylenimine (PEI) in water have been prepared. One series consists of binary copolymers containing methacrylic acid (MAA) and poly(ethylene glycol) monomethyl ether monomethacrylate (PEGMA) in molar ratios ranging from 20:80 to 80:20, as well as the two homopolymers, poly(MAA) and poly(PEGMA). Another series contains an equimolar amount of MAA and PEGMA, together with between one and ten percent of a third, hydrophobic monomer, butyl methacrylate (BMA).,/p, ,p, Both binary and ternary copolymers show lower critical solution temperatures, LCSTs, ranging from 60.8°C to 1.5°C depending on composition. Furthermore, complex coacervation occurs upon addition ...
I have classified these factors in the aforementioned categories as they arent important from a general reader or patients point of view. I feel the need to mention them to acknowledge the fact that many patients blindly assign the blame for non-retentive dentures on their dentists instead of thinking about any other factor that may have been the cause.. Denture adhesives are used by many denture wearers and prescribed by dentists. Yet, many prosthodontists have a negative attitude towards the use of denture adhesives as they assume that to advocate their use is a means to compensate for deficiencies in clinical and technical procedures.. The fact, however, is denture adhesives increases denture retention and thereby improve chewing ability, reduce denture wobble, increase comfort and confidence, and decrease the amount of food particles collected under the dentures. Moreover, adhesives undoubtedly provide the sense of security and satisfaction, but they should use them if prescribed by their ...

The objectives of the program were two-fold: select commercially available thermosetting adhesive systems and formulations that could be used as underwater adhesive systems; and demonstrate the feasibility of converting selected adhesive formulations to capsular adhesive systems thereby insuring improved versatility and logistic properties. As design goals, the selected capsular adhesive systems were required to meet the following requisites: Yield a cure time of 30 seconds or less; bond to both dry and wet (submerged) substrates of wood, metal, and concrete; and, yield a bond strength of 0.5 psi after a 30 second cure. Studies revealed that none of the commercially available systems met all of the contract requirements. Of the systems evaluated, the polysulfides and cyanoacrylates did meet more of the requirements than any of the other systems. Capsular adhesive systems possessing various design goal requirements were developed using the polysulfide, polyester, epoxy and cyanoacrylate systems.(

Its unlikely that the adhesive is the main problem. There is a web of material between the adhesive films and the solvent will get off the top adhesive, but not penetrate the web to the adhesive underneath.. Id second the suggestion for the hot air gun to allow scraping of the web with a hardwood or hard, hi-temp plastic scraper or a sharp putty knife if the material underneath the tape will tolerate it, followed by an appropriate solvent, such as WD40.. Otherwise, take a paper shop towel saturated with solvent and let it sit on the tape as long as it takes to work in around the edges of the web and get to the adhesive underneath.. Most tape adhesives have a fairly low creep strength and if you can lift a corner of the tape and pull just hard enough to not break the web, you can SLOOOWLY peel the tape from one end to the other. My wife has never figured this out, so I get the task of peeling tapes and labels from whatever. It takes patience and time, but if you have it, it makes for a clean ...

In this review the current state of the art on mechanical properties of pure wood adhesives is summarised and discussed. Conventionally, mechanical adhesive properties were characterised by means of macroscopic tensile or bending tests of ex-situ cured adhesive films. More recently, nanoindentation was also used to characterise such ex-situ specimens, but more importantly, this method allows the mechanical characterisation of adhesive bond lines in-situ. Mechanical tests reveal high variability between, but notably also within specific groups of adhesives. For example, the modulus of elasticity covers a wide range of more than two magnitudes ranging from 0.1 GPa up to 15 GPa. Significant differences in adhesive stiffness were observed for adhesives intended to be used for solid wood products compared to wood based composite adhesives, the latter showing higher modulus values. In addition to mechanical adhesive properties as such, factors possibly influencing adhesive performance such as ...
The effects of surface active additives on rolling-element fatigue life were investigated with the five-ball fatigue tester at conditions where classical subsurface initiated rolling-element fatigue is the sole mode of failure. Test balls of AISI 52100, AISI M-50, and AISI 1018 were run with an acid-treated white oil containing either 2.5 percent sulfurized terpene, 1 percent didodecyl phosphite, or 5 percent chlorinated wax. In general, it was found that the influence of surface active additives was detrimental to rolling-element fatigue life. The chlorinated-wax additive significantly reduced fatigue life by a factor of 7. The base oil with the 2.5 percent sulfurized-terpene additive can reduce fatigue life by as much as 50 percent. No statistical change in fatigue life occurred with the base oil having the 1 percent didodecyl-phosphite additive. The additives used with the base oil did not change the ranking of the bearing steels where rolling-element fatigue life was of subsurface origin.
