The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

They are of medical importance because some fimbriae mediate the attachment of bacteria to cells via adhesins (ADHESINS, BACTERIAL). Bacterial fimbriae refer to common pili, to be distinguished from the preferred use of "pili", which is confined to sex pili (PILI, SEX).

Non-antibody proteins secreted by inflammatory leukocytes and some non-leukocytic cells, that act as intercellular mediators. They differ from classical hormones in that they are produced by a number of tissue or cell types rather than by specialized glands. They generally act locally in a paracrine or autocrine rather than endocrine manner.
An serine-threonine protein kinase that requires the presence of physiological concentrations of CALCIUM and membrane PHOSPHOLIPIDS. The additional presence of DIACYLGLYCEROLS markedly increases its sensitivity to both calcium and phospholipids. The sensitivity of the enzyme can also be increased by PHORBOL ESTERS and it is believed that protein kinase C is the receptor protein of tumor-promoting phorbol esters.

The forward rate of binding of surface-tethered reactants: effect of relative motion between two surfaces. (1/1085)

The reaction of molecules confined to two dimensions is of interest in cell adhesion, specifically for the reaction between cell surface receptors and substrate-bound ligand. We have developed a model to describe the overall rate of reaction of species that are bound to surfaces under relative motion, such that the Peclet number is order one or greater. The encounter rate between reactive species is calculated from solution of the two-dimensional convection-diffusion equation. The probability that each encounter will lead to binding depends on the intrinsic rate of reaction and the encounter duration. The encounter duration is obtained from the theory of first passage times. We find that the binding rate increases with relative velocity between the two surfaces, then reaches a plateau. This plateau indicates that the increase in the encounter rate is counterbalanced by the decrease in the encounter duration as the relative velocity increases. The binding rate is fully described by two dimensionless parameters, the Peclet number and the Damkohler number. We use this model to explain data from the cell adhesion literature by incorporating these rate laws into "adhesive dynamics" simulations to model the binding of a cell to a surface under flow. Leukocytes are known to display a "shear threshold effect" when binding selectin-coated surfaces under shear flow, defined as an increase in bind rate with shear; this effect, as calculated here, is due to an increase in collisions between receptor and ligand with increasing shear. The model can be used to explain other published data on the effect of wall shear rate on the binding of cells to surfaces, specifically the mild decrease in binding within a fixed area with increasing shear rate.  (+info)

Adhesion energy of receptor-mediated interaction measured by elastic deformation. (2/1085)

We investigated the role of receptor binding affinity in surface adhesion. A sensitive technique was developed to measure the surface energy of receptor-mediated adhesion. The experimental system involved a functionalized elastic agarose bead resting on a functionalized glass coverslip. Attractive intersurface forces pulled the two surfaces together, deforming the bead to produce an enlarged contact area. The Johnson-Kendall-Roberts (JKR) model was used to relate the surface energy of the interaction to the elasticity of the bead and the area of contact. The surface energies for different combinations of modified surfaces in solution were obtained from reflection interference contrast microscopy (RICM) measurements of the contact area formed by the bead and the coverslip. Studies with surfaces functionalized with ligand-receptor pairs showed that the relationship between surface energy and the association constant of the ligand binding has two regimes. At low binding affinity, surface energy increased linearly with the association constant, while surface energy increased logarithmically with the association constant in the high affinity regime.  (+info)

Steric effects of N-acyl group in O-methacryloyl-N-acyl tyrosines on the adhesiveness of unetched human dentin. (3/1085)

We have prepared various O-methacryloyl-N-acyl tyrosines (MAATY) to reveal the relationship between molecular structure near carboxylic acid and adhesive strength of MAATY-HEMA type adhesive resin to unetched dentin. In this study, we attempted to change the steric hindrance effect without changing the HLB value, i.e., introducing an iso-acyl group instead of n-acyl group into MAATY. O-methacryloyl-N-ethylbutyryl tyrosine (MIHTY) showed significantly lower adhesive strength when compared with O-methacryloyl-N-hexanoyl tyrosine even though both MAATY have the same HLB value. The possible explanation of the significantly different adhesive strength was that the 2-ethylbutyryl group in MIHTY was bulky, resulting in inhibition of the hydrogen bonding of the carboxylic group. The HLB value is independent of the steric effect of molecular structure, and thus the steric factor should be taken into consideration for the explanation of different adhesive strengths within the adhesive monomers having the same HLB value but different molecular structures.  (+info)

Adhesion of adhesive resin to dental precious metal alloys. Part I. New precious metal alloys with base metals for resin bonding. (4/1085)

New dental precious metal alloys for resin bonding without alloy surface modification were developed by adding base metals (In, Zn, or Sn). Before this, binary alloys of Au, Ag, Cu, or Pd containing In, Zn, or Sn were studied for water durability and bonding strength with 4-META resin. The adhesion ability of the binary alloys was improved by adding In equivalent to 15% of Au content, Zn equivalent to 20% of Ag content, and In, Zn, or Sn equivalent to 5% of Cu content. There was no addition effect of the base metals on Pd, however 15% of In addition improved adhesion with Pd-based alloys containing equi-atomic % of Cu and Pd. The alloy surfaces were analyzed by XPS and showed that oxides such as In2O3, ZnO, or SnO play an important role in improving the adhesive ability of the alloys.  (+info)

Adhesion of adhesive resin to dental precious metal alloys. Part II. The relationship between surface structure of Au-In alloys and adhesive ability with 4-META resin. (5/1085)

Adhesion of 4-META to Au-In alloy was improved by adding In equivalent to .15% of Au content. On the basis of the results of Au-In alloys analyzed by XPS, the present study investigated the reason why adhesion of the Au-In alloy was improved. The O 1s spectrum could be separated into three oxygen chemical states, In2O3, chemisorbed H2O, and physisorbed H2O. The amount of chemisorbed H2O decreased remarkably with increasing amount of In. It is considered that the poor adhesive ability of the pure gold and alloys containing only small amounts of In was due to the chemisorbed H2O molecules and insufficient indium oxide on the alloy surface. It was established that excellent adhesion requires an oxide with chemical affinity for 4-META to cover at least 50% of the alloy surface.  (+info)

Coating of extracorporeal circuit with heparin does not prevent sequestration of propofol in vitro. (6/1085)

Propofol is sequestered in extracorporeal circuits, but the factors responsible for the phenomenon are mostly unknown. We have compared two extracorporeal circuits (oxygenators, reservoirs and tubings) coated with heparin with two corresponding uncoated circuits for their capacity to sequester propofol in vitro. Three experiments were conducted with each circuit. The circuit was primed with a mixture of Ringer's acetate solution and whole blood, and the study conditions (pump flow, temperature, pH) were standardized. Propofol was added to the solution to achieve a concentration of 2 micrograms ml-1. These studies were followed with concentrations of 10- and 100-fold to assess possible saturation of propofol binding. Serial samples were obtained from the circulating solution for measurement of propofol concentration. Propofol concentrations decreased to 22-32% of the initial predicted concentration of 2 micrograms ml-1 in the circuits (no significant difference between circuits). With greater concentrations, the circuits did not become saturated with propofol, even with the highest predicted concentration of 200 micrograms ml-1. We conclude that propofol was sequestered in extracorporeal circuits in vitro, irrespective of coating the circuit with heparin.  (+info)

An ex vivo investigation into the bond strength of orthodontic brackets and adhesive systems. (7/1085)

The aim of this study was to compare the shear bond strength of Adhesive Precoated Brackets (APC) with that of two types of uncoated bracket bases, Straight-Wire and Dyna-Lock. Two types of orthodontic adhesives were used, Transbond XT and Right-On. Three different curing times were evaluated with the APC brackets in order to find the best. Adhesive remnants on the enamel surface following debond were evaluated using the Adhesive Remnant Index (Artun and Bergland, 1984). Bond strengths ranged from 11.00 to 22.08 MPa. For both types of brackets Transbond produced a significant increase in bond strength compared to Right-On. The Dyna-Lock/Right-On combination produced the poorest results. APC brackets cured for 40 s had similar bond strengths to uncoated brackets fixed by means of Transbond. Overall, 79 per cent of specimens had less than half the tooth surface covered with adhesive following debond. Significantly more adhesive remained on tooth surfaces following debond of the Straight-Wire/Right-On group than any other bracket/adhesive combination. Bond strengths were higher with light-cured Transbond than with chemically-cured Right-On. When Transbond is used in association with APC brackets a 40-second cure time is recommended.  (+info)

The influence of epitope availability on atomic-force microscope studies of antigen-antibody interactions. (8/1085)

The ability of the atomic-force microscope (AFM) to detect interaction forces between individual biological molecules has recently been demonstrated. In this study, force measurements have been obtained between AFM probes functionalized with the beta-subunit of human chorionic gonadotrophin (betahCG) and surfaces functionalized with anti-betahCG antibody. A comparison of the obtained results with previous anti-ferritin antibody-binding data identifies differences when the antigen molecule expresses only a single epitope (betahCG), rather than multiple epitopes (ferritin), for the monoclonal antibodies employed. Specifically, the probability of observing probe-sample adhesion is found to be higher when the antigen expresses multiple epitopes. However, the periodic force observed in the adhesive-force distribution, due to the rupture of single antigen-antibody interactions, is found to be larger and more clearly observed for the mono-epitopic system. Hence, these findings indicate the potential of the AFM to distinguish between multivalent and monovalent antibody-antigen interactions, and demonstrate the influence of the number of expressed epitopes upon such binding studies.  (+info)

Methods and compositions are provided for enhancing the bioadhesive properties of polymers used in drug delivery devices. The bioadhesive properties of a polymer are enhanced by incorporating a anhydrideoligome into the polymer to enhance the ability of the polymer to adhere to a tissue surface such as a mucosal membrane. Anhydrideoligomes which enhance the bioadhesive properties of a polymer include water-insoluble anhydrideoligomes such as water-insoluble metal oxides, including oxides of calcium, iron, copper and zinc. The anhydrideoligomes can be incorporated within a wide range of polymers including proteins, polysaccharides and synthetic biocompatible polymers. In one embodiment, metal oxides can be incorporated within polymers used to form or coat drug delivery devices, such as microspheres, which contain a drug or diagnostic agent. The metal oxides can be provided in the form of a fine dispersion of particles on the surface of a polymer that coats or forms the devices, which enhances the ability
The remarkable underwater adhesion strategy employed by mussels has inspired bioadhesives that have demonstrated promise in connective tissue repair, wound closure, and local delivery of therapeutic cells and drugs. While the pH of oxygenated blood and internal tissues is typically around 7.4, skin and tumor tissues are significantly more acidic. Additionally, blood loss during surgery and ischemia can lead to dysoxia, which lowers pH levels of internal tissues and organs. Using 4-armed PEG end-capped with dopamine (PEG-D) as a model adhesive polymer, the effect of pH on the rate of intermolecular cross-linking and adhesion to biological substrates of catechol-containing adhesives was determined. Adhesive formulated at an acidic pH (pH 5.7-6.7) demonstrated reduced curing rate, mechanical properties and adhesive performance to pericardium tissues. Although a faster curing rate was observed at pH 8, these adhesives also demonstrated reduced mechanical and bioadhesive properties when compared to ...

Tissue engineering is a multidisciplinary field that aims to repair or regenerate lost or damaged tissues and organs in the body. For the repair of certain load-bearing parts of the body, success of a tissue regeneration strategy can be dependent on scaffold adhesion or integration with the surrounding host tissue to prevent dislocation. One such area is the regeneration of the intervertebral disc (IVD). The objective of this work is to generate a bioadhesive polymer that, in addition to bonding with tissue, can support encapsulated cell survival post-adhesion. Thermosensitive poly(N-isopropylacrylamide) (PNIPAAm) was grafted with chondroitin sulfate (CS) (PNIPAAm-g-CS) and blended with aldehyde-modified CS to achieve covalent adhesion upon contact with tissue. Extracellular matrix (ECM) loaded lipid vesicles (liposomes) were incorporated into the copolymer for enhanced cellular biocompatibility. The bioadhesive strength was evaluated in contact with porcine ear cartilage. Additionally, the cytotoxicity
We found no difference in the adhesive force or the motion of clinging digits between before and after death treatments (figure 2b,f). Although previous research and anecdotes have shown that some adhesion can still occur after death in geckos [15-17], our controlled experiments are the first to show that dead animals maintain the ability to adhere with the same force as living animals. These results refute the hypothesis that actions by a living animal, such as muscle recruitment or neural activity, are required for gecko feet to generate our high measured forces.. The high variation in adhesive force among trials on both living and dead geckos is surprising. Despite the controlled pulling force applied by our pulling device, peak adhesive force spanned a range that was 19.9 times the mean body weight. When averaged among individuals, the mean coefficients of variation for adhesive force before and after death were 0.33 and 0.36, respectively. After pooling alive and dead trials, a multiple ...
Stickiness is an important texture attribute in many food systems, but its meaning can vary by person, product, and throughout mastication. This variability and complexity makes it difficult to devise analytical tests that accurately and consistently predict sensory stickiness. Glass transition temperature (T-g) is a promising candidate for texture prediction. Our objective is to elucidate the temporal profile of stickiness in order to probe the relationship between T-g and dynamic stickiness perception. Nine caramel samples with diverse texture and thermal profiles were produced for sensory testing and differential scanning calorimetry. Sixteen trained panelists generated stickiness-relevant terms to be used in a subsequent temporal dominance of sensation (TDS) test with the same panelists. Following the TDS study, these panelists also rated samples for overall tactile and oral stickiness. Stickiness ratings were then correlated to TDS dominance parameters across the full evaluation period and within

The science on display is the capillary action of the water - that is, how the flower drinks even without its roots. This ability draws water against the force of gravity up the stem and into the petals. It works because the water evaporating from the petals and leaves of the plant pulls water up the narrow tubes in the stem (the xylem) to replace that which is lost. The tubes need to be narrow so that the combination of the surface tension of the water (caused by cohesion in the water - how well it sticks to itself) and the adhesive forces between the water and the walls of the xylem are strong enough to lift the water against the force of gravity. The adhesive forces are proportional to the diameter of the tube, whilst the weight of the water is proportional to this diameter squared - hence a smaller diameter favours the adhesive forces ...

Some people love washing their cars, but many folks would appreciate having the fresh-from-the-showroom look without all of the effort. And dont forget the environmental impact of car washing, which drains water reserves and spills pollutants into endangered wetlands. If only our cars would clean themselves.. Thanks to some researchers at the Eindhoven University of Technology in the Netherlands, we may be closer to a perpetually polished Prius. The scientists didnt invent a brand-new nanotechnology. Instead, they took an existing water-resistant product, already in use on some vehicles, and made it better. The original coating worked because it came embedded with nanocapsules in its surface. Those tiny capsules both repelled water and contained cleaning agents or paint droplets so that when they were ruptured, say by a key scratch, they released their contents and healed the blemish. Unfortunately, the capsules had a limited shelf life. To extend the self-cleaning/healing properties of the ...

Despite profound interest in the mechanics and performance of the gecko adhesive system, relatively few studies have focused on performance under conditions that are ecologically relevant to the natural habitats of geckos. Because geckos are likely to encounter surfaces that are wet, we used shear force adhesion measurements to examine the effect of surface water and toe pad wetting on the whole-animal performance of a tropical-dwelling gecko (Gekko gecko). To test the effect of surface wetting, we measured the shear adhesive force of geckos on three substrate conditions: dry glass, glass misted with water droplets and glass fully submerged in water. We also investigated the effect of wetting on the adhesive toe pad by soaking the toe pads prior to testing. Finally, we tested for repeatability of the adhesive system in each wetting condition by measuring shear adhesion after each step a gecko made under treatment conditions. Wetted toe pads had significantly lower shear adhesive force in all ...

Downloadable! To investigate the banking sector integration across euro area countries in terms of loan interest rate stickiness, we estimate structural loan rate curves for 12 euro area countries using time-varying regressions with stochastic volatility. Our results show that the loan rates are sticky to a policy interest rate in all countries for all loan maturities, the degree of stickiness differs across the countries, and the degree of difference is more prominent for longer loan maturities. For short-term loans, the loan rate stickiness decreases and for intermediate- and long-term loans the loan rate stickiness converge to average levels during the sample periods. Banking integration in the euro area is not yet complete, but the degree of heterogeneity in the loan rate stickiness decreases.
Cell adhesion to surfaces represents the basis for niche colonization and survival. Here we establish serial quantification of adhesion forces of different cell types using a single probe. The pace of single-cell force-spectroscopy was accelerated to up to 200 yeast and 20 mammalian cells per probe when replacing the conventional cell trapping cantilever chemistry of atomic force microscopy by underpressure immobilization with fluidic force microscopy (FluidFM). In consequence, statistically relevant data could be recorded in a rapid manner, the spectrum of examinable cells was enlarged, and the cell physiology preserved until approached for force spectroscopy. Adhesion forces of Candida albicans increased from below 4 up to 16 nN at 37°C on hydrophobic surfaces, whereas a Δhgc1-mutant showed forces consistently below 4 nN. Monitoring adhesion of mammalian cells revealed mean adhesion forces of 600 nN of HeLa cells on fibronectin and were one order of magnitude higher than those observed for ...

Specialized tarsal setae with an attachment function have evolved independently several times among arthropods (Gorb and Beutel, 2001). They enable effective, dynamic attachment to various surfaces during locomotion. In hairy adhesive pads, the adhesive performance is enhanced by multiple contact sites (Jagota and Bennison, 2002), a high compliance of setae (Persson, 2003) and terminal contact elements (Persson and Gorb, 2003), and a hierarchical organization (Kim and Bushan, 2007; Gasparetto et al., 2009). Adhesion enhancement due to multiple contacts can be explained by the involvement of various effects, such as crack propagation prevention (Chung and Chaudhury, 2005) and surface roughness compatibility (Peressadko and Gorb, 2004a; Bhushan et al., 2006).. Under natural conditions, animals attach to unpredictable surfaces of very different roughness, which normally reduces adhesion even in the hairy attachment devices of geckos and insects. In previous work, it has been shown that there is a ...

Hydraulic Design of Self-Cleaning Sewage Tunnels. A description of the different factors affecting the hydraulic design of self-cleaning sewage tunnels with a free water surface is presented. It is found that the two most important problems involved are related to shear stress distribution and critical shear stress to secure self-cleaning. Based on a shear stress distribution normally assumed for open channels, a trapezoidal bottom shape is suggested.

In figure 1, a nanoparticle is shown dispersed in a liquid, which also contains surface active molecules (adhesion molecules). The particle diffuses towards the cell surface, makes contact and then wanders around the local area. It may find a point of entry or it may dislodge and continue its Brownian exploration of the fluid [4]. This process is similar to that involved in a virus infecting lung cells. A paper in this volume shows that the presence of nanoparticles can influence the progress of influenza virus infection [5].. To start this volume, we describe van der Waals force which is the source of adhesion in geckos that run up walls and under ceilings without any adhesive [6]. Next, by considering adhesion of ants feet under water [7], it becomes clear that the presence of a liquid has a large influence on van der Waals adhesion, decreasing the adhesion force by an order of magnitude. However, there is also the confusing effect that liquids may hugely increase the contact area, which may ...

Mandible with 6 to 7 teeth; maxillary palps 6-segmented; labial palps 4-segmented; erect setae on dorsum of head randomly placed; typically with abundant erect setae on head, scapes, legs and dorsum of mesosoma, although a few species lack erect setae on head, scapes and legs. Eyes typically well developed and placed midlength and laterally on head. Dorsal mesosomal setae arranged loosely in pairs; propodeum lacking erect setae (with one exception); propodeum with a low- to high-domed dorsal face; generally overall mesosoma shape compact. Nylanderia workers can generally be easily distinguished from other formicines based on the presence of 6 mandibular teeth, erect macrosetae on the scapes and legs, and paired erect macrosetae on the pronotum and mesonotum. These morphological features are considered synapomorphies for the genus, and will effectively separate this genus from other genera. Overall, the body shape for most Nylanderia workers is compact and robust in that the mesosomal regions are ...

Sample preparation: The samples were placed in specially designed sample cuvettes, which exposed a flat circular surface with a diameter of 5 cm for measurement. Samples were placed in the cuvettes such that the interior of the fillets was exposed for autofluorescence measurements. Before measurements, the samples were conditioned at 18°C for at least one hour.. Fluorescence spectroscopy: The samples were excited with a 332 nm interference filter where after the emission was measured from 360 to 600 nm. Two spectra were collected and the average was used for further analysis.. Texture: Texture was evaluated instrumentally by compression using a Texture Analyzer TA.XT2 equipped with a cylindrical plunger. The plunger was pressed into the fillets at a constant rate of 1 mm-1 until it reached 90 % of the sample height. The resistance force was recorded at the maximum force obtained during compression. Two measurements were performed on each fillet, and the mean value was used for the analysis. The ...

These forces, which act between stable molecules, are weak compared to those appearing in chemical bonding. To explain this, we refer to the article on intermolecular forces, where it is discussed that an intermolecular force has four major contributions. In general an intermolecular potential has a repulsive part, prohibiting the collapse of molecular complexes, and an attractive part. The attractive part, in turn, consists of three distinct contributions (i) The electrostatic interactions between charges (in the case of molecular ions), dipoles ...

Whether an object will pull electons off another object or get electrons pulled off it depends on the configuration of the molecules. All materials can be ranked in an order of increasing likeliness to lose electrons. The charge seperation that occurs requires that the two objects be from different parts of the list (one higher, one lower) otherwise each of the two objects will be equally as likely to lose electrons, and therefore each would be just as likely to gain them. There would be no net gain or loss of electrons for either object ...

Downloadable (with restrictions)! In this paper we show that results on the effects of fiscal shocks in Galí, López-Salido and Vallés (2007) rely on a high degree of price stickiness and a large percentage of financially constrained agents. Real rigidities in the form of habit persistence, fixed firm-specific capital and Kimball demand curves interact in interesting ways with nominal and financial rigidities and allow us to reproduce the same consumption multiplier as Galí et al. (2007) under only two and a half quarters of price stickiness, instead of four, and only 30 per cent of constrained agents instead of 50 per cent. Therefore, real rigidities are useful in the study of fiscal shocks in addition to monetary and productivity shocks as has been shown in the previous literature, though rule-of-thumb consumption remains too crude a mechanism for accounting for the hump-shaped response of consumption found in the data.
While NPS correlates with usability, simply tracking your raw score alone does not necessarily give you information to pinpoint the factors that would improve your actual experience. We recommend adding an extra step to add some color to responses, because NPS is really just a starting point. The real value in NPS is using it as a jumping off point to asking more in depth questions. The fact that a user gave you an NPS score of 4 or 9 is not as important as why they gave those ratings. For example, simply asking something along the lines of, can you tell me more about why you [would or would not] recommend us to a friend? can be very helpful ...
