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.Water: A clear, odorless, tasteless liquid that is essential for most animal and plant life and is an excellent solvent for many substances.

Lipophilization of somatostatin analog RC-160 with long chain fatty acid improves its antiproliferative and antiangiogenic activity in vitro. (1/73)

The therapeutic potential of the somatostatin analogue RC-160 having antiproliferative activity, is limited by its short serum half life. To overcome this limitation, fatty acids namely butanoic acid and myristic acid were conjugated to the N-terminal residue of RC-160. The lipophilized derivatives of RC-160 were synthesized, purified by reverse phase HPLC and characterized by ES-mass spectroscopy. The antiproliferative activity of lipophilized derivatives of RC-160 on the growth of MIA-PaCa2 (human pancreatic carcinoma), DU145 (human prostate carcinoma), ECV304 (human umbilical chord endothelioma), as well as their antiangiogenic activity was evaluated in vitro. The relative stability of myristoyl-RC-160 towards degradation by proteases and serum was also determined. Myristoyl-RC-160 exhibited significantly higher antiproliferative efficacy than RC-160, on the above cell lines (P<0.01). Receptor binding assays, demonstrated that the affinity of RC-160 towards somatostatin receptors remains unaltered by myristoylation. Unlike RC-160, the myristoylated derivative was found to have significantly greater resistance to protease and serum degradation (P<0.01). Myristoyl-RC-160 exhibited significantly greater antiproliferative activity on ECV304, than RC-160 (P<0.01). Myristoyl RC-160 could also inhibit capillary tube formation more efficiently than RC-160 in a dose dependent manner, suggesting that it possessed enhanced antiangiogenic activity in vitro (P<0.001). Lipophilization of RC-160 with long chain fatty acids like myristic acid endows it with improved antiproliferative and antiangiogenic activity, stability and therapeutic index.

Cryo-scanning electron microscopy observations of vessel content during transpiration in walnut petioles. Facts or artifacts? (2/73)

The current controversy about the "cohesion-tension" of water ascent in plants arises from the recent cryo-scanning electron microscopy (cryo-SEM) observations of xylem vessels content by Canny and coworkers (1995). On the basis of these observations it has been claimed that vessels were emptying and refilling during active transpiration in direct contradiction to the previous theory. In this study we compared the cryo-SEM data with the standard hydraulic approach on walnut (Juglans regia) petioles. The results of the two techniques were in clear conflict and could not both be right. Cryo-SEM observations of walnut petioles frozen intact on the tree in a bath of liquid nitrogen (LN(2)) suggested that vessel cavitation was occurring and reversing itself on a diurnal basis. Up to 30% of the vessels were embolized at midday. In contrast, the percentage of loss of hydraulic conductance (PLC) of excised petiole segments remained close to 0% throughout the day. To find out which technique was erroneous we first analyzed the possibility that PLC values were rapidly returned to zero when the xylem pressures were released. We used the centrifugal force to measure the xylem conductance of petiole segments exposed to very negative pressures and established the relevance of this technique. We then analyzed the possibility that vessels were becoming partially air-filled when exposed to LN(2). Cryo-SEM observations of petiole segments frozen shortly after their xylem pressure was returned to atmospheric values agreed entirely with the PLC values. We confirmed, with water-filled capillary tubes exposed to a large centrifugal force, that it was not possible to freeze intact their content with LN(2). We concluded that partially air-filled conduits were artifacts of the cryo-SEM technique in our study. We believe that the cryo-SEM observations published recently should probably be reconsidered in the light of our results before they may be used as arguments against the cohesion-tension theory.  (+info)

Retinal adhesion in light- and dark-adapted rabbits. (3/73)

The effects of pigmentation and light exposure on retinal adhesion in rabbits have been investigated in a complete factorial experiment. Ocular pigmentation did not significantly influence retinal adhesion. A significant difference in retinal adhesive forces was found between light and dark adaptation. The force required to detach the retina from the retinal pigment epithelium was 20 per cent greater in light-adapted eyes than in dark-adapted eyes. These observations suggest that the positional change of rhodopsin molecules in the outer segment disk membranes occurring with light exposure and the resultant alteration in interdisk electrostatic forces may play an important role in retinal adhesion.  (+info)

Global analysis of the Deinococcus radiodurans proteome by using accurate mass tags. (4/73)

Understanding biological systems and the roles of their constituents is facilitated by the ability to make quantitative, sensitive, and comprehensive measurements of how their proteome changes, e.g., in response to environmental perturbations. To this end, we have developed a high-throughput methodology to characterize an organism's dynamic proteome based on the combination of global enzymatic digestion, high-resolution liquid chromatographic separations, and analysis by Fourier transform ion cyclotron resonance mass spectrometry. The peptides produced serve as accurate mass tags for the proteins and have been used to identify with high confidence >61% of the predicted proteome for the ionizing radiation-resistant bacterium Deinococcus radiodurans. This fraction represents the broadest proteome coverage for any organism to date and includes 715 proteins previously annotated as either hypothetical or conserved hypothetical.  (+info)

Generation of the streaming potential by liposomes in cylindrical capillary. Experimental data. (5/73)

A model of creation a streaming potential U as a result of colloidal particle movement in flow in a capillary has been described previously (Zawada 1996) as well as the systems for measurement (Zawada 1990, 1991). The filling of capillary with a solution of liposomes results in a labile adsorbance of liposomes on a capillary glass and changes the measured streaming potential. In order to minimalize these adverse effects, the capillary was covered with phospholipid layer of different composition. Some concentrations of stearylamine as a component of the phospholipid layer may fully compensate the surface charge of the glass capillary and can reduce the liposomes adsorption. The streaming potential of the liposomes solution depends on the ionic strength of the electrolyte and is smaller than the zeta potential for similar liposomes. This suggests that only a part of ions of the liposome ion atmosphere participate in creating of the streaming potential. These are the ions from the hydrodynamic slipping layer. The regression analysis of the relationships between streaming potential U and concentration of liposomes and next ionic strength of the electrolyte gave the value of the surface potential psi0 and the thickness of the hydrodynamic slipping layer d, that is independent of the ionic strength.  (+info)

The shape parameter of liposomes and DNA-lipid complexes determined by viscometry utilizing small sample volumes. (6/73)

A minicapillary viscometer utilizing <0.5 ml of sample at a volume fraction of <0.1% is described. The calculated a/b of DPPC/DPPG multilamellar liposome was 1.14 as prolate ellipsoids and a/b of dioleoylpropyltrimethyl ammonium methylsulfate-DNA complex at a charge ratio of 4:1 (+/-) was 3.7 as prolate ellipsoids or 4.9 as oblate ellipsoids. The deviation of shape from perfect sphere is thus expressed quantitatively in more than two significant figures. In these measurement, the necessary amount of DNA is <0.5 mg.  (+info)

Iohexol in serum determined by capillary electrophoresis. (7/73)

Iohexol, a nonionic compound used as a contrast medium for angiography and as a measure of the glomerular filtration rate, was quantified in serum by capillary electrophoresis. Comparable results were obtained for serum samples deproteinized with acetonitrile or analyzed directly after 50-fold dilution with borate buffer. Serum samples were electrophoresed for 2.6 min at 12 kV in a borate buffer with detection at 254 nm and with 3-isobutyl-1-methylxanthine as internal standard. Acetonitrile deproteinization gave a greater sensitivity than did sample dilution. Between-run CVs were between 4.7% and 6.7%, and within-run CVs were between 2.5 and 3.2%. Analytical recoveries were 95-105%. Results of the method compared well with those by high-performance liquid chromatography (slope 0.96, intercept 0.005 g/L). This method demonstrates the potential of capillary electrophoresis for rapid and simple quantification of small molecules.  (+info)

High-pressure fluorescence correlation spectroscopy. (8/73)

We demonstrate that a novel high-pressure cell is suitable for fluorescence correlation spectroscopy (FCS). The pressure cell consists of a single fused silica microcapillary. The cylindrical shape of the capillary leads to refraction of the excitation light, which affects the point spread function of the system. We characterize the influence of these beam distortions by FCS and photon-counting histogram (PCH) analysis and identify the optimal position for fluorescence fluctuation experiments in the capillary. At this position within the capillary, FCS and photon-counting histogram experiments are described by the same equations as used in standard FCS experiments. We report the first experimental realization of fluorescence fluctuation spectroscopy under high pressure. A fluorescent dye was used as a model system for evaluating the properties of the capillary under pressure. The autocorrelation function and the photon count distribution were measured in the pressure range from 0 to 300 MPa. The fluctuation amplitude and the diffusion coefficient show a small pressure dependence. The changes of these parameters, which are on the order of 10%, are due to the pressure changes of the viscosity and the density of the aqueous medium.  (+info)

Supplement The capillary action pertains to the movement of a liquid through a narrow space as a result of the forces of cohesion, adhesion, and surface tension. Cohesion is the sticking together of alike molecules whereas adhesion is the sticking together of unlike molecules. Surface tension is the intermolecular attraction that pulls the molecules of the liquid inward from the surface resulting in the least surface area possible. These forces work together and produce a capillary action. If a capillary tube is made of glass or any other substance that is polar, water will spontaneously climb up inside it without having to be pumped in any way. The smaller the tube, the higher the water climbs. The attraction is so great between the water molecules and the molecules of the tube that water will climb in defiance of the force of gravity. Capillary action is seen in plants when water is able to ascent from the root upward through the xylem tissues of a plant. Water uptake involving capillary ...
Even though we usually think of water as running downhill, it can indeed flow upwards using a process called capillary action. This is the very scientific principal that explains how water goes from the soil upwards into the stem of plants. Plants contain many vein like tubes that carry water from the plants roots upwards to the plants highest leafs via capillary action. Try this experiment to see capillary action in action.. ...
Capillary action is where the surface tension of the water can pull the water into small gaps. Any gaps in your building that are less than 5mm (1/4″) could allow water into your building. Capillary action is extremely powerful, and can even overcome gravity, allowing water to creep up a detail and into your building. The good news is that its extremely easy to solve. All you need is a gap that is wider than 5 mm (1/4″). If you look at good detailing you will notice that there are often gaps at the bottom of flashings that will prevent water from creeping up the detail.. ...

A sample acquisition device includes a capillary array configured to draw in a sample and retain the sample by capillary action. The capillary array may be coupled to an elongated member, such as a stem or a hollow tube, which defines a longitudinal axis extending in a first direction. In some embodiments, the capillary array defines a major sample acquisition surface that extends in a second direction different than the first direction. A ratio of the major sample acquisition surface area to maximum volume retained by the capillary array may be selected to minimize physical binding between the capillary array and sample. In some embodiments, the device may include a feedback mechanism to indicate the relative pressure applied to a sample source with the sample acquisition device. In addition, in some embodiments, the sample acquisition device may include a suction source to help draw the sample into the capillary array.

In use the sampling member is placed adjacent to an incision site with the second portion of the wicking member positioned to have the bodily fluid first contact the wicking member and thereby draw the fluid from the incision site to the inlet opening. In related embodiments there is provided a sampling system and method which further includes a lancing device to create the incision and optionally expression members to urge the bodily fluid from the incision, preferably in an integrated unit.
The present invention relates to the selection of materials which are particularly useful as fluid distribution material for being used in disposable absorbent articles by being characterized in that they have a wicking time of less than 120 seconds and a cumulative flux of more than 0.075 grams/cm2/second for said preferential fluid distribution direction at 12.4 cm height, when applying the Vertical Wicking Test. A further useful selection criteria for such materials is a non-isotropic fluid distribution behavior, expressed in that the wicking time in the preferential distribution direction is less than 80% of the wicking time of perpendicular direction at 8.3 cm height, when applying the same test.
Microsatellite DNA or short tandem repeat (STR) 1 sequences are important in many types of genetic analysis, such as loss of heterozygosity testing, linkage analysis, gene mapping and discovery, paternity and forensic identity testing, evolutionary studies, and clinical diagnostics (1)(2)(3)(4)(5)(6)(7)(8)(9)(10). STR analysis is highly informative because of the large number (,5200) of mapped loci available (11) and because these loci are highly polymorphic and widely distributed across the genome (6). STR analysis usually consists of locus-specific PCR amplification followed by electrophoretic separation of the products (3)(10)(12). Many STR-based genetic studies, such as linkage analysis, gene mapping, and loss of heterozygosity testing, require the screening of large numbers of microsatellite loci in thousands of individuals (1)(3)(4)(5)(10). To address the needs of these and future STR-based studies, new generations of genetic analysis devices and methods that can rapidly perform sensitive, ...

On July 5th, 2004, Jim McKenney brought up the problem of moisture in his raised beds in spite of their being covered and impervious to rain. Two possible solutions might be to treat the bed as a scree similar to those naturally found or constructed in which alpine plants are grown. The size of the beds matter is great enough to allow drainage and air flow to a fair depth, and the moisture below in more dense material (earth) would both evaporate up and be carried by capillary action to a far lesser degree. In fact, watering on occasion might be required. The second technique might be to copy bonsai growers and go for a uniform mixture that is leached to remove all particulate matter smaller than is required for stability and growth. Local conditions would dictate exactly what size matter is used. In my case, Ive gone so far as to use childrens marbles as a base up to a small layer of sifted compost to add some organic matter on top.

As noted above, OPG is an endogenous inhibitor of RANKL signaling that limits arterial calcium accumulation during development. Recently, the impact of pharmacological inhibition of RANKL by OPG has been evaluated in the above preclinical models of atherosclerosis and arterial calcification. Interestingly, very distinct responses are observed with OPG administration in LDLR−/− and apoE−/− mice.28,43 Morony et al28 first evaluated the male LDLR−/− mouse, the dynamics of endogenous RANKL/OPG signaling during disease initiation and progression, and the impact of exogenous OPG administration. Serum RANKL measurements demonstrated that progression of vascular disease over 5 months of dietary cholesterol challenge closely tracks the progressive recovery of circulating RANKL after an early phase of diet-induced suppression.28 Early diet-induced increases in OPG, a presumed adaptive mechanism to protect against untoward RANKL signaling,36 exhibited no dynamic change with progression.28 As ...
Care for Bedding Products:. Laundering: Machine wash warm or cold, gentle cycle. Use a mild laundry detergent, and avoid liquid chlorine bleach (LCB), fabric softener, dryer sheets, and washer or dryer balls since these products will diminish the wicking ability of the fabric. If you use chlorine-free bleach, be careful to not pour it directly onto your bedding. You must pre-dilute it before adding to wash. Tumble Dry on low or medium heat and remove promptly from dryer to prevent excessive wrinkling. Stains: for body or facial oils, you can pre-wash or soak the sheets with ¼ cup of Dawn dishwashing liquid, as Dawn is a natural degreaser, then launder as usual. As soon as you see an oil stain, pre-treat so that the stain is not set in the dryer. For all other stains, you can Spray Oxy Clean, use bleach, or Grandmas Miracle Spot Remover directly onto the stain, then launder as usual.

An integrated bodily fluid sampling device includes a lancet, a test strip attached to the lancet, and a flexible sheet extending from the test strip. The lancet and the flexible sheet form a gap sized to draw bodily fluid onto the test strip via capillary action. Further, a sampling end portion of the flexible sheet is shaped to enhance capillary action of the sheet. In one form, a removable film covers the lancet and forms a seal with the flexible sheet such that the seal surrounds a lancet tip. In another form, an insulating layer covers a portion of the lancet to prevent electrical interference between the lancet and an electrical testing system on the test strip and ensure an accurate analysis of the bodily fluid.
A method and device for determining the presence of an analyte in a sample suspected of containing the analyte is disclosed. The method involves contacting a test solution containing the sample, an antibody for the analyte, and a conjugate of the analyte and a label with a contact portion of a strip of bibulous material capable of being traversed by the test solution through capillary action. The strip contains a first receptor capable of binding to said conjugate. The first receptor is non-diffusively bound to a situs on the strip separate from the contact portion of the strip. The strip further contains a second receptor capable of binding the antibody to the analyte between the situs and the contact portion. The second receptor is non-diffusively bound to the strip. At least a portion of the test solution is allowed to traverse the strip by capillary action and thereby contact the situs. The strip is exposed to a signal producing means capable of interacting with the label to produce a signal in

Most startup option grants come with a 90-day exercise window when an employee leaves the company (voluntarily or not). This is standard practice. Essentially the problem is that this can force employees to take a major personal financial hit to exercise their options when they leave or are fired, and perversely this is worse the more the company has grown during their time there. (Exercising options comes with a tax hit proportional to the amount the stock has increased in value since the option was granted.). Theres an easy solution: when an employee leaves, convert their ISOs to NSOs and extend the exercise window.. Today my employer TrueAccord extended our exercise window to seven years for people with two years or more at the company. Im proud of what this means - this is a progressive move and it shows a dedication to the employees of the company. In general Im skeptical about equity as a carrot for startup employees (see here for an extremely skeptical view), but this is the right way ...
The Americans come to see him as a superman. One character points out the contrast: "Hes made of iron, while were made of flesh and blood. Hungry flesh and blood!" Willy instead credits his endurance to "clean living".. The Fundamental Attribution Error (and more generally, The Person and the Situation) say that when we see a person acting a certain way we think its because of who they are or how they were born. But instead its usually because of what theyve done, how theyve trained, or the context they face (that is invisible to us). So while the Americans think Willys physical endurance is genetic ("they truly are the master race") he sees the years of physical training he endured, and perhaps even the additional pressure he faces, as the one German on the boat, to prove himself.. At least this is the story for about 15 minutes of the movie. In fact Willy is cheating. He has food and water squirreled away, which is the hidden context that really accounts for the observed ...

Advances in bioinformatics and high-throughput genetic analysis increasingly allow us to predict the genetic basis of adaptive traits. These predictions can be tested and confirmed, but the molecular-level changes-i.e. the molecular adaptation-that link genetic differences to organism fitness remain generally unknown. In recent years, a series of studies have started to unpick the mechanisms of adaptation at the molecular level. In particular, this work has examined how changes in protein function, activity, and regulation cause improved organismal fitness. Key to addressing molecular adaptations is identifying systems and designing experiments that integrate changes in the genome, protein chemistry (molecular phenotype), and fitness. Knowledge of the molecular changes underpinning adaptations allow new insight into the constraints on, and repeatability of adaptations, and of the basis of non-additive interactions between adaptive mutations. Here we critically discuss a series of studies that ...

The study of capillarity is in the midst of a veritable explosion. Hence the temptation to write a new book, aiming at an audience of students. What is offered here is not a comprehensive review of the latest research but rather a compendium of principles. How does one turn a hydrophilic surface into one that is hydrophobic, and vice versa? We will describe a few solutions. Some rely on chemical treatments, such as coating a surface with a molecular layer. Others are based on physics, for instance by controlling the roughness of a surface. We will also examine the dynamics of wetting. Drops that spread spontaneously do so at a rate that slows down with time. They can be tricked into covering large areas by spreading them suddenly. We will describe a few of the many facets of their dynamical properties. Special additives are required for water to foam. Foams are desirable in a shampoo but can be a nightmare in a dishwasher detergent. Antifoam agents have been developed and are well known, but how ...

The term Capillary Fringe as it applies to the area of the weather can be defined as In hydrologic terms, the soil area just above the water table where water can rise up slightly through the cohesive force of capillary action. This layer ranges in depth from a couple of inches, to a few feet, and it depends on the pore sizes of the materials. The capillary fringe is also called the capillary zone. ...
Capillary matting is a useful accessory for pot plant growers. It distributes water and nutrients evenly through capillary action and so if your hose or overhead spray system has watered some plants more than others the capillary matting will redistribute the excess to those plants that have not received enough.
Kim Wonjung and his colleagues at MIT, in the US, have worked out how the tongue of the hummingbird can achieve a capillary action.

Principle:. Southern transfer is the classic method used to move DNA (usually in the form of restriction fragments) from agarose gels to a solid support, e. g. nylon membrane. The DNA is bound to the membrane in the same position (relative to other fragments) as in the gel. The use of a membrane in hybridization experiments is far more convenient than trying to hybridize in a gel. In a Southern transfer the DNA is first denatured in the gel, then the gel is placed on a buffer-saturated spongey surface, the membrane positioned on top of the gel, and dry blotting papers are added on top of the membrane. The buffer moves by capillary action through the gel and into the papers above. The denatured DNA in the gel moves passively with the buffer and is stopped by the membrane. DNA is permanently bound to the membrane by baking or cross-linking with UV. This protocol is designed for transferring DNA for RFLP analysis. The optimum size range of DNA fragments detected this way is 2 - 25 kb.. Time ...
95% of a humans DNA is made of introns, and these make up core sequences. These sequences are different in all human except for identical twins.. Each sequence will still come from one parent.. Genetic fingerprinting is made up of 6 stages:. Stage 1:. Extraction- A small amount of DNA is extracted from the individuals blood and then copied through the PCR method.. Stage 2:. Digestion- This is then cut into fragments by restriction endonuclease.. Stage 3:. Separation- Gel electropherosis is used to split the fragments in order of size. The fragments are then immersed in alkali in order to split them into single strands. Separation 2- A nylon membrane is then placed over the gel with absorbent sheets attached behind it. The liquid is drawn up via capillary action. Ultraviolet rays are used to fix the DNA fragments onto the membrane. They will be in the exact same positions as they were on the gel.. Stage 4:. Hybridisation- DNA probes are used to join to the fragments. Specific temperatures and ...
A method and apparatus for collecting and separating cells, particles or the like from body fluid or the like for microscopic diagnosis is disclosed. Fluid is sucked by capillary action through a fluid-permeable surface (17) which holds back the cell material to be investigated. An apparatus suitable for this purpose comprises a filter container (2) having an upper and a lower opening, the lower opening of which is covered by a fluid-permeable cell carrier element (10), at least one filter segment (11) and a suction insert (12) being arranged in the filter container (2).
One part (phloem, maybe analogous to arteries) is for the sugars produced by the leaves, called sap. The second is xylem, (maybe analogous to veins), conducting water and minerals up from the roots. Xylem is a dead, porous tissue inside the cambium. Using tiny, hydrophilic vessels allows water tension to "hold it all together", while the negative pressure at the top of a plant pulls continuously upwards. How much pressure is needed at the top of a plant? Well, about 19 atmospheres of negative pressure for a hundred-meter tall tree, or ~2MPa. (Compared to this, our blood pressure is negligible, at 0.015 MPa.) The xylem is carefully constructed to prevent bubbles from forming, and from spreading if they do form, helping the natural cohesion of water (which causes the phenomena of capillary action and surface tension) to keep the water column intact under such intense pressures ...
Hands are coated with resin after 20 minutes of rubbing.Several drippers irrigate each of the 15-25 gallon containers. The system is calibrated so that about 20% of the high EC water, translating to 800 ppm dissolved solids, drains from the container. The vents were also repaired so they automatically open and close. A sophisticated humidistat-thermostat, rather than a workers subjective judgement, controls the top opening units, which run the length of the glasshouse.. The clones are located across the aisle. The entire section is covered with medium knit, white shade cloth. A curtain lowers the light level and maintains a higher level of humidity, while allowing some air circulation. This area had previously been hand watered daily using a wand. This time the capillary action system was reactivated. This system uses a stream of water traveling slowly through a non-woven cloth at a 1/40 slant. The cloth is covered with a black polyethylene plastic sheet punctured with small holes throughout. ...
Ultra-Etch etchant is a 35% phosphoric acid solution. It features ideal viscosity, which, along with the use of the Blue Micro™ or Inspiral™ Brush tip, facilitates precision placement and superior control. Ultra-Etch etchant is self-limiting in its depth of etch (average depth of 1.9μm with 15-second etch),1 creating an etch pattern that adhesives can penetrate for increased bond strength and reduced sensitivity. Studies demonstrate that Ultra-Etch etchants unique self-limiting chemistry creates an optimal surface to receive resin.2 Though Ultra-Etch etchant is viscous, it can penetrate into the smallest fissures or occlusal surfaces due to physical and chemical properties that promote capillary action. Its ideal viscosity maintains a layer thick enough to prevent premature drying.. ...

Ive had problems with the automatic rocker and the lower volume (400 ul/well) that is suggested in this protocol. I think the rocker may actually promote drying of the center of the well by drawing the fluid to the side of the well via capillary action ...
The One Step K2 Drug of Abuse Test is an immunoassay based on the principle of competitive binding. Drug which may be present in the urine specimen compete against their respective drug conjugate for binding sites on their specific antibody. During testing, a urine specimen migrates upward by capillary action. A drug, if present in the urine specimen below its cut-off concentration, wil not saturate the binding sites of its specific antibody. The antibody wil then react with the drug-protein conjugate and a visible colored line wil show up in the test line region of the specific drug strip. The presence of drug above the cut-off concentration wil saturate al the binding sites of the antibody. Therefore, the colored line wil not form in the test line region. A drug-positive urine specimen will not generate a colored line in the specific test line region of the strip because of drug competition, while a drug-negative urine specimen will generate a line in the test line region because of the ...

A distinctive absorbent article includes an absorbent core having multiple absorbent layers, wherein the absorbent layers interact in such a manner which preferentially locates absorbed liquid in an appointed, high saturation wicking layer. The localization of the liquid within this wicking layer increases the potential of this layer to move liquid through capillary action due to the higher saturation level and increased amount of liquid available. In particular aspects, at least one primary layer region can have a heterogeneous structure. In additional configurations, the at least one primary layer region can include a plurality of two or more sublayers.
0096] It has been determined that the clamshell opening speed (i.e., the speed at which the cone is moved away from the cup bottom, the action of which is one step in a sequence required for the extraction of the wafer from the cup/cone clamshell assembly) has an effect on rinsate wicking into the contact area and edge defects. Without being limited by any particularly model or theory, it is believed that slower opening speeds cause less suction in the contact area resulting in reduced wicked amounts. However, further reducing the opening speeds causes the wicking volume to increase, which may be due to capillary action while wafer is waiting to be picked out of the cup. FIG. 14A is a plot of the normalized rinsate volume wicked into the contact area as a function of the opening speeds two different spinning durations. In both tests, a fixed spin rotation speed of 600 rpm was used for either two seconds (line 1402) or four seconds (line 1404). The spinning was performed after a two second rinse ...

Capillary phenomena include various cases of equilibrium and flow of fluid surface under the action of surface tension forces and of external forces, primarily gravity. In the simplest case when the external forces are absent, e.g., under weightlessness conditions, a limited fluid volume takes the shape of a sphere due to surface tension forces. This state corresponds to a stable equilibrium of the fluid since a sphere has the minimum surface and, consequently, the minimum surface energy. As shown in Figure 1, when the liquid (1) comes in contact with the gas vapor (2) and the solid (3), the shape of the free liquid surface depends on wetting. Interaction of surface tension forces at the liquid-gas ...

We describe a practical method of fabricating surface-enhanced Raman spectroscopy (SERS) substrates based on dip-coating poly-l-lysine derivatized microscope slides in a gold colloidal suspension. The use of only commercially available starting materials in this preparation is particularly advantageous, aimed at both reducing time and the inconsistency associated with surface modification of substrates. The success of colloid deposition has been demonstrated by scanning electron microscopy (SEM) and the corresponding SERS response (giving performance comparable to the corresponding traditional colloidal SERS substrates). Reproducibility was evaluated by conducting replicate measurements across six different locations on the substrate and assessing the extent of the variability (standard deviation values of spectral parameters: peak width and height), in response to either Rhodamine 6G or Isoniazid. Of particular interest is the observation of how some peaks in a given spectrum are more ...
This perspective presents an overview of single-molecule surface-enhanced Raman scattering (sm-SERS). Our overview is organized as a brief theoretical background, discussion of the factors that enhance SERS, various experimental preparations for inserting a single molecule in a hot spot, recent sm-SERS exper Plasmonics and spectroscopy
For centuries it has been known that wetting liquids penetrate porous materials if the pores are sufficiently small. In some cases the liquid penetration is desired, like in kitchen paper or diapers, in other systems the penetration should be minimised or avoided, like in water repellent textiles or paper printing. Either way capillary flow has been studied extensively starting from smooth to rough surfaces and from single capillaries to porous systems. However, one field, which is lacking attention is the behaviour of capillary flow in porous gels. How does a semi-solid material influence capillary flow? Possible applications could be to absorb solutes or cell solutions in porous gels with the aim to get an even distribution of those. In this thesis alginate and agarose gels are used to study capillary flow. A thorough study of the gel characteristics including rheology measurements and investigation of the microstructure using two different gelation mechanisms gave the basis to study capillary action
Leading chemists and engineers concisely explain the principles behind microchip capillary electrophoresis and demonstrate its use in a variety of biochemical applications, ranging from the analysis of DNA, proteins, and peptides to single cell analysis and measuring the impact of surface modification on flow in microfluidic channels. Since surface chemistry must be carefully considered for optimal operation at this scale, the authors also discuss methods of both adsorbed and covalent surface modification for its control. Fabrication methods for producing microchips with glass, poly(dimethylsiloxane), and other polymers are also provided so that even novices can produce simple devices for standard separations. Microchip Capillary Electrophoresis: Methods and Protocols provides a practical starting point for either initiating research in the field of microchip capillary electrophoresis or understanding the full range of what can be done with existing systems ...
G-Quadruplex (G4) structures of a human telomeric 24-mer (5′-TTAGGGTTAGGGTTAGGGTTAGGG-3′) sequence (Tel24) stabilized by sodium and potassium ions have been assessed using surface-enhanced Raman scattering (SERS) spectroscopy. The distinctive SERS spectra of Tel24 in the presence of 100 mM Na+ and 100 mM K+ were obtained and the SERS bands characteristic of the antiparallel baskettype and the mixed hybrid (3+1) structures, respectively, were identified and assigned. The influence of the SERS - active substrate on the scattering enhancement was studied using citrate- and chloride-covered silver nanoparticles, in the absence and presence of the aggregating agent (0.1 M Na2SO4 and 0.1 M K2SO4). The highly reproducible SERS spectra of Tel24 obtained in various SERS active media indicated the same adsorption mechanism of the cation - stabilized G-quadruplexes onto the metal surface, regardless of the silver colloid. The remarkable resemblance between the circular dichroism (CD) spectra of the ...
