5'-Nucleotidase activity of mouse peritoneal macrophages. II. Cellular distribution and effects of endocytosis. (1/3739)

The diazonium salt of sulfanilic acid (DASA) can inactivate about 80% of the total 5'-nucleotidase of viable macrophages. The remaining 20% can be inactivated if the cells are first lysed in detergent, and presumably represents an intracellular pool of 5'-nucleotidase. The bulk of this pool may represent cytoplasmic vesicles derived from plasma membrane by endocytosis. This internal compartment is expanded up to threefold immediately after the cells have ingested a large latex load. This is consistent with previous observations on the internalization of 5'-nucleotidase in latex phagosomes. In latex-filled cells this intracellular pool of enzyme is inactivated over a few hours, and the cells then slowly increase their enzyme activity to nearly normal levels. However, 24 h after latex ingestion the metabolism of 5'-nucleotidase in these recovered cells is abnormal, as the rate of enzyme degradation is about twice the normal rate, and the DASA-insensitive enzyme pool in these cells is strikingly diminished. This may reflect effects of the accumulated indigestible particles on the fate of incoming pinocytic vesicles or on newly synthesized plasma membrane precursor. Another endocytic stimulus, concanavalin A, also reduces the total cell 5'-nucleotidase activity. This effect, which is time and temperature dependent, can be prevented by the competitive sugar alpha-methyl mannose. The concanavalin A inhibition can be reversed in the absence of new protein synthesis or in cells cultivated in serum-free conditions. It is not known whether the effect of concanavalin A on 5'-nucleotidase depends upon the interiorizaiton of plasma membrane or is strictly associated with events at the cell surface.  (+info)

In vitro and in vivo activities of NS-718, a new lipid nanosphere incorporating amphotericin B, against Aspergillus fumigatus. (2/3739)

We evaluated the in vitro and in vivo potencies of a new lipid nanosphere that incorporates amphotericin B (AmB), NS-718, against Aspergillus fumigatus. The in vitro activity of NS-718 (the MIC at which 90% of strains are inhibited [MIC90], 0.25 microgram/ml) against 18 isolates of A. fumigatus was similar to that of deoxycholate AmB (D-AmB; Fungizone; MIC90, 0.25 microgram/ml), but NS-718 was more potent than liposomal AmB (L-AmB; AmBi-some; MIC90, 1.0 microgram/ml). The in vivo efficacy of NS-718 in a rat model of invasive pulmonary aspergillosis was compared with those of D-AmB and L-AmB. A low dose (1 mg/kg of body weight) of L-AmB was ineffective (survival rate, 0%), although equivalent doses of D-AmB and NS-718 were more effective (survival rate, 17%). However, a higher dose of NS-718 (3 mg/kg) was more effective (survival rate, 100%) than equivalent doses of D-AmB and L-AmB (survival rate, 0%). To explain these differences, pharmacokinetic studies showed higher concentrations of AmB in the plasma of rats treated with NS-718 than in the plasma of those treated with D-AmB. Our results suggest that NS-718, a new preparation of AmB, is a promising antifungal agent with activity against pulmonary aspergillosis.  (+info)

Quantitative study of polymer conformation and dynamics by single-particle tracking. (3/3739)

We present a new method for analyzing the dynamics of conformational fluctuations of individual flexible polymer molecules. In single-particle tracking (SPT), one end of the polymer molecule is tethered to an immobile substratum. A microsphere attached to the other end serves as an optical marker. The conformational fluctuations of the polymer molecule can be measured by optical microscopy via the motion of the microsphere. The bead-and-spring theory for polymer dynamics is further developed to account for the microsphere, and together the measurement and the theory yield quantitative information about molecular conformations and dynamics under nonperturbing conditions. Applying the method to measurements carried out on DNA molecules provides information complementary to recent studies of single DNA molecules under extensional force. Combining high precision measurements with the theoretical analysis presented here creates a powerful tool for studying conformational dynamics of biological and synthetic macromolecules at the single-molecule level.  (+info)

Adhesion energy of receptor-mediated interaction measured by elastic deformation. (4/3739)

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)

A region of the Yersinia pseudotuberculosis invasin protein enhances integrin-mediated uptake into mammalian cells and promotes self-association. (5/3739)

Invasin allows efficient entry into mammalian cells by Yersinia pseudotuberculosis. It has been shown that the C-terminal 192 amino acids of invasin are essential for binding of beta1 integrin receptors and subsequent uptake. By analyzing the internalization of latex beads coated with invasin derivatives, an additional domain of invasin was shown to be required for efficient bacterial internalization. A monomeric derivative encompassing the C-terminal 197 amino acids was inefficient at promoting entry of latex beads, whereas dimerization of this derivative by antibody significantly increased uptake. By using the DNA-binding domain of lambda repressor as a reporter for invasin self-interaction, we have demonstrated that a region of the invasin protein located N-terminal to the cell adhesion domain of invasin is able to self-associate. Chemical cross-linking studies of purified and surface-exposed invasin proteins, and the dominant-interfering effect of a non-functional invasin derivative are consistent with the presence of a self-association domain that is located within the region of invasin that enhances bacterial uptake. We conclude that interaction of homomultimeric invasin with multiple integrins establishes tight adherence and receptor clustering, thus providing a signal for internalization.  (+info)

Effect of acute normovolemic hemodilution on distribution of blood flow and tissue oxygenation in dog skeletal muscle. (6/3739)

Acute normovolemic hemodilution (ANH) is efficient in reducing allogenic blood transfusion needs during elective surgery. Tissue oxygenation is maintained by increased cardiac output and oxygen extraction and, presumably, a more homogeneous tissue perfusion. The aim of this study was to investigate blood flow distribution and oxygenation of skeletal muscle. ANH from hematocrit of 36 +/- 3 to 20 +/- 1% was performed in 22 splenectomized, anesthetized beagles (17 analyzed) ventilated with room air. Normovolemia was confirmed by measurement of blood volume. Distribution of perfusion within skeletal muscle was determined by using radioactive microspheres. Tissue oxygen partial pressure was assessed with a polarographic platinum surface electrode. Cardiac index (3.69 +/- 0.79 vs. 4.79 +/- 0.73 l. min-1. m-2) and muscle perfusion (4.07 +/- 0.44 vs. 5.18 +/- 0.36 ml. 100 g-1. min-1) were increased at hematocrit of 20%. Oxygen delivery to skeletal muscle was reduced to 74% of baseline values (0.64 +/- 0.06 vs. 0.48 +/- 0.03 ml O2. 100 g-1. min-1). Nevertheless, tissue PO2 was preserved (27.4 +/- 1.3 vs. 29.9 +/- 1. 4 Torr). Heterogeneity of muscle perfusion (relative dispersion) was reduced after ANH (20.0 +/- 2.2 vs. 13.9 +/- 1.5%). We conclude that a more homogeneous distribution of perfusion is one mechanism for the preservation of tissue oxygenation after moderate ANH, despite reduced oxygen delivery.  (+info)

Estimation of rat muscle blood flow by microdialysis probes perfused with ethanol, [14C]ethanol, and 3H2O. (7/3739)

We used the perfused rat hindquarter to evaluate whether the microdialysis ethanol technique can be used to qualitatively estimate nutritive skeletal muscle blood flow. Four microdialysis probes were inserted in different hindlimb muscles in each of 16 rats. Hindquarters were perfused at blood flow rates ranging from 0 to 21 ml. 100 g-1. min-1. The microdialysis probes were perfused at 2 microliter/min with perfusate containing ethanol, [14C]ethanol, and 3H2O. Within and between experiments outflow-to-inflow ratios (o/i) generally varied inversely with blood flow. When a low flow or no flow was maintained in hindquarters, o/i ratios first increased with time (for at least 60 min) and then leveled off. The long time constant impaired detection of rapid oscillations in blood flow, especially at low blood flow rates. Contractions per se apparently decreased o/i ratios independent of blood flow. Ethanol and [14C]ethanol o/i ratios did not differ. 3H2O o/i paralleled ethanol and [14C]ethanol o/i ratios but it was significantly lower. In conclusion, differences in skeletal muscle blood flow can be detected by the microdialysis technique. However, the slow changes in o/i, in particular at low blood flow rates, limit the usefulness of the technique for measuring dynamic changes in blood flow; caution must also be exerted during muscle contractions. 3H2O and [14C]ethanol are good alternatives to ethanol in the determination of blood flow by microdialysis.  (+info)

DNA hybridization on microparticles: determining capture-probe density and equilibrium dissociation constants. (8/3739)

Many DNA-probe assays utilize oligonucleotide-coated microparticles for capture of complementary nucleic acids from solution. During development of these assays, as well as in other particle-based nucleic acid applications, it is useful to know both the amount of duplex formation expected under various experimental conditions and the coating density of the capture oligonucleotide on the particle surface. We examined the simplest form of a DNA-probe microparticle assay: hybridization of a particle-bound capture oligonucleotide to its solution-phase complement. Fluorescein-labeled solution-phase oligonucleotide was hybridized to varying amounts of particles, and the amount of labeled oligonucleotide remaining in solution at equilibrium was measured. We present a simple two-state, all-or-none model for bimolecular hybridization of non-self-complementary sequences that can be used to calculate the equilibrium dissociation constant ( Kd ) from hybridization data. With experimental conditions where both the Kd value and the concentration of capture probe in the reaction are small relative to the concentration of labeled complementary oligonucleotide in the reaction, density of the capture probe on the particle's surface can also be determined. Kd values for particle-based hybridization were different from those obtained from solution-phase thermodynamic parameters. At higher temperatures, hybridization on particles was more efficient than hybridization in solution.  (+info)

The poly(orthoester) (POE)-poly(D,L-lactide-co-glycolide) (50:50) (PLGA) double-walled microspheres with 50% POE in weight were loaded with hydrophilic bovine serum albumin (BSA) and hydrophobic cyclosporin A (CyA). Most of the BSA and CyA was entrapped within the shell and core, respectively, because of the difference in their hydrophilicity. The morphologies and release mechanisms of proteins-loaded double-walled POE/PLGA microspheres were investigated. Scanning electron microscope studies revealed that the CyA-BSA-loaded double-walled POE/PLGA microspheres yielded a more porous surface and PLGA shell than those without BSA. The neat POE and PLGA yielded slow and incomplete CyA and BSA release. In contrast, nearly complete BSA and more than 95% CyA were released in a sustained manner from the double-walled POE/PLGA microspheres. Both the BSA- and CyA-BSA-loaded POE/PLGA microspheres yielded a sustained BSA release over 5 days. The CyA release pattern of the CyA-loaded double-walled POE/PLGA ...

In vitro sustained release of human immunoglobulin G from biodegradable microspheres | ScholarBank@NUSIn vitro sustained release of human immunoglobulin G from biodegradable microspheres | [email protected]
The in vitro controlled release kinetics of human immunoglobulin G (IgG) of different loadings from microspheres of the biodegradable polymers poly(L-lactide) (PLA) and poly(D,L-lactide-co-glycolide) (PLGA) were investigated. The microspheres were prepared by a double-emulsion technique. The release profiles exhibited an initial burst followed by a period of slow release, with PLA microspheres showing a faster rate of release than PLGA microspheres. The release rate increased with an increase in drug loading. Scanning electron microscopy (SEM) observations revealed wide differences in the morphology of microspheres made from different polymers. Drug loading had no significant effect on the morphology of the microspheres. Laser scanning confocal micrographs demonstrated a homogeneous drug distribution within the microspheres. Results from SEM and mass loss studies revealed no significant extent of polymer erosion after 50 days of release. Modeling studies within the first 50 days of incubation ...

Hollow glass microspheres made from a low heat conductivity glass composition containing a high vacuum and a thin metal coating deposited on the inner wall surface of the microspheres are described. The hollow glass microspheres are used to make superior insulation materials in the construction of highly efficient solar energy collectors. The hollow glass microspheres are made by forming a liquid film of molten glass across a coaxial blowing nozzle, applying a metal vapor blowing gas at a positive pressure on the inner surface of the glass film to blow the film and form an elongated cylinder shaped liquid film of molten glass. A transverse jet is used to direct an inert entraining fluid over and around the blowing nozzle at an angle to the axis of the blowing nozzle. The entraining fluid as it passes over and around the blowing nozzle fluid dynamically induces a pulsating or fluctuating pressure field at the opposite or lee side of the blowing nozzle in the wake or shadow of the coaxial blowing nozzle.

Approximately 10 ml of the above solution was taken (if further dilution is necessary) in another volumetric flask and made it 100 ml with phosphate buffer. Absorbance value was determined using UV spectrophotometer at a wavelength of 242 nm. Using the absorbance value, the amount of drug entrapped was determined with the help of standard curve. Percent drug loading and drug entrapment efficiency was calculated by using the following equation. % drug Loading = (Actual drug loading / Weighed quantity of microspheres) X 100. Drug entrapment efficiency (%) = (Actual drug loading / ...
Synthesis of biodegradable polymer-mesoporous silica composite microspheres for DNA prime-protein boost vaccinationSynthesis of biodegradable polymer-mesoporous silica composite microspheres for DNA prime-protein boost vaccination
DNA vaccines or proteins are capable of inducing specific immunity; however, the translation to the clinic has generally been problematic, primarily due to the reduced magnitude of immune response and poor pharmacokinetics. Herein we demonstrate a composite microsphere formulation, composed of mesoporous silica spheres (MPS) and poly(d,l-lactide-co-glycolide) (PLGA), enables the controlled delivery of a prime-boost vaccine via the encapsulation of plasmid DNA (pDNA) and protein in different compartments. Method with modified dual-concentric-feeding needles attached to a 40 kHz ultrasonic atomizer was studied. These needles focus the flow of two different solutions, which passed through the ultrasonic atomizer. The process synthesis parameters, which are important to the scale-up of composite microspheres, were also studied. These parameters include polymer concentration, feed flowrate, and volumetric ratio of polymer and pDNA-PEI/MPS-BSA. This fabrication technique produced composite ...

Novel magnetic-antimicrobial-fluorescent multifunctional hybrid microspheres with well-defined nanostructure were synthesized by the aid of a poly(glycidyl methacrylate) (PGMA) template. The hybrid microspheres were fully characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FTIR), X-ray diffraction (XRD) and digital fluorescence microscope. The as-synthesized microspheres PGMA, amino-modified PGMA (NH2-PGMA) and magnetic PGMA (M-PGMA) have a spherical shape with a smooth surface and fine monodispersity. M-PGMA microspheres are super-paramagnetic, and their saturated magnetic field is 4.608 emu·g−1, which made M-PGMA efficiently separable from aqueous solution by an external magnetic field. After poly(haxemethylene guanidine hydrochloride) (PHGH) functionalization, the resultant microspheres exhibit excellent antibacterial performance against both Gram-positive and Gram-negative bacteria.

Functional magnetic particles are formed by dissolving a mucopolysaccharide such as chitosan in acidified aqueous solution containing a mixture of ferrous chloride and ferric chloride. As the pH of the solution is raised magnetite is formed in situ in the solution by raising the pH. The dissolved chitosan is a polyelectrolyte and forms micelles surrounding the granules at pH of 8-9. The chitosan precipitates on the granules to form microspheres containing the magnetic granules. On addition of the microspheres to waste aqueous streams containing dissolved ions, the hydroxyl and amine functionality of the chitosan forms chelates binding heavy metal cations such as lead, copper, and mercury and the chelates in turn bind anions such as nitrate, fluoride, phosphate and borate.
Scientists create dual-modality microbeads to improve identification of disease biomarkersScientists create dual-modality microbeads to improve identification of disease biomarkers
The process of creating these beads is quite simple, according to Sathe. The surface of the beads contains a long-chain carbon molecule that makes the beads hydrophobic, meaning they repel water. The beads are dissolved in butanol and washed several times. Then the beads are counted and optical and magnetic nanocrystals are added to the suspension either simultaneously or sequentially. After 15-20 minutes, the butanol is removed to get rid of any remaining nanoparticles that didnt get incorporated into the beads and the beads are washed with ethanol. Then the beads are coated with a polymer that creates a hydrophilic surface on the beads. This allows the beads to be functionalized by adding antibodies or DNA molecules to the surface that will capture the target molecules.. These beads are dual-function -- both optical and magnetic -- but according to Sathe, more functions can be added to the beads. "Adding them is as easy as adding the nanoparticles into the solution. You just have to make sure ...
WGA PVT PEI TYPE A 500 MG | PerkinElmerWGA PVT PEI TYPE A 500 MG | PerkinElmer
The treatment of PVT-WGA SPA beads with positively charged polyethyleneimine (PEI) blocks potential non-specific binding sites on the SPA bead surface. There are two SPA bead types available with PEI treatment. The PVT-WGA-PEI type A SPA beads are treated with PEI prior to the coupling of WGA to the PVT SPA bead. The PVT-WGA PEI type B SPA beads are treated with PEI after the WGA coupling stage. The PVT-WGA-PEI type A and type B SPA beads exhibit different characteristics with regard to the non-specific binding of radiolabelled ligand directly to the SPA bead. Therefore, both bead types should be evaluated when deciding which SPA bead to use and both are included in the Select-a-Bead Kit. The binding capacity of both bead types for cell membrane protein remains 10-30 μg membrane protein per milligram of SPA bead.. SPA Scintillation beads are microspheres containing scintillant which emit light in the blue region of the visible spectrum. As a result, these beads are ideally suited to use with ...

PFH, which is a liquid at ambient temperature, is non-toxic and has been used in the preparation of multifunctional microspheres for medical and pharmaceutical applications (Giesecke & Hynynen 2003). The mechanism for the preparation of hollow microspheres takes advantage of its properties of immiscibility and volatility (Pisani et al. 2006). PFH and PMSQ were injected with appropriate flow rates under an applied voltage, in which the electrical forces acted on the driving liquid and led to the establishment of the cone. The PMSQ solution was accelerated by the electrical field, while the flow of PFH was dominated by viscous stresses. Hence, the electrical forces acting on the PMSQ film drive the inner viscous liquid so that both liquids flow steadily with the same velocity. Thus, concentric droplets can be obtained with PMSQ around the PFH; these are stable and retain their integrity owing to their immiscibility. The core material (PFH) can change phase from liquid to gas at ambient temperature ...

EPS puffed beads are created by applying steam to EPS resin in an enclosed chamber. The Pentane gas in each piece of resin expands from the heat causing the beads to grow by 30 to 35 times their original size. When they are fully puffed the beads are primarily made up of air. The puffed beads are then transferred to a drying chamber where they are subjected to dry air and from there into large poly bags for shipping. For very large applications the puffed beads can be blown directly into a 53 trailer.. Another major application for puffed EPS beads today is in the manufacture of bean bag chairs and poufs. Bean bag chairs, popular in the 60s, have seen resurgence in popularity in the past several years. The puffed EPS beads are sold to manufacturers in truckload quantities and blown or poured into the shells using specialized equipment.. ...

Practical design of composite materials suggests a need for an improved quantitative understanding of the interaction between acoustic waves and microspheres. In this work, we first investigate the Mie resonance of a single spherical microsphere embedded in polymer by referring to the elements of the scattering matrices. It shows that a hollow glass microsphere presents a similar monopole resonance as an air microsphere, but the resonance of a hollow glass microsphere occurs at a higher frequency with a wider bandwidth than that of an air microsphere. Then, using the multiple scattering method, we show that the low-frequency gap of a periodic array of microspheres in polymer is mainly induced by the monopole resonance of the single microsphere, and find a wide band gap under very low concentrations of the microspheres. The viscosity of the components induces the energy dissipation under the resonant scattering, and the attenuation of ultrasonic longitudinal waves in the polymer slab is dominated ...

The pH-responsive core-shell microspheres of poly(styrene-co-methylacrylic acid) (PS-co-PMAA) containing a polystyrene (PS) core and a poly(methylacrylic acid) (PMAA) shell are synthesized by one-stage soap-free copolymerization and the catalyst system palladium-iminodiacetic acid (IDA-Pd) is immobilized on the outer shell-layer of the core-shell microspheres to form the quasi-homogeneous and easily accessible catalyst PS-co-PMAA-IDA-Pd. This quasi-homogeneous PS-co-PMAA-IDA-Pd catalyst is highly dispersed in the reaction medium just like a homogeneous one and can be separated like a heterogeneous catalyst by adjusting the pH of the reaction medium. Suzuki reactions employing the quasi-homogeneous PS-co-PMAA-IDA-Pd catalyst are efficiently performed in water as the sole solvent under mild conditions such as room temperature. The PS-co-PMAA-IDA-Pd catalyst is also used in Heck reactions of a wide range of aryl halides with styrene and proves to be efficient in aqueous solution. The ...

Hierarchical N-doped TiO2 microspheres with exposed (001) facets [N-TiO2-(001)] were synthesized through a simple, fluorine-free solvothermal reaction with subsequent thermal treatment. The results show that the hierarchical N-TiO2-(001) microspheres are made up of numerous TiO2 nanosheets, and that isopropylamine (IPAN) acts as both the nitrogen source and the capping and shape-controlling agent that generates the high-energy (001) facets. In addition, IPAN is also effective in increasing the onset temperature of the phase transformation of TiO2 from anatase to rutile. Compared with the commercially available P25 TiO2, the as-prepared TiO2 microspheres exhibit good photocatalytic activity and high stability under visible-light irradiation. The high photocatalytic performance is derived from the synergy effect of N-doping and the separation of photogenerated electrons and holes among different facets, as evidenced by surface photovoltage spectroscopy. ...

Anal beads - WikipediaAnal beads - Wikipedia
Anal beads are available in many sizes, with individual beads measuring from 25 mm in diameter to 125 mm diameter or larger. Most users enjoy beads of approximately 45 mm, but most will become more adventurous with experience, and try larger sizes. Anal beads are commonly made of silicone, plastic, rubber, latex, glass or metal and end with a ring or similar handle designed for pulling. The purpose of this ring is to prevent the beads from becoming fully lodged in the rectum, and to ease removal. The beads may either be joined flexibly, requiring individual insertion, or by a semi-rigid thin shaft, allowing anal insertion in a single motion. Both arrangements are forms of the sexual art of "beading off". The many nerve endings of the sphincter provide arousal both during insertion and removal, and larger beads may create feelings of pressure while in the rectum. Some anal beads are enhanced with vibration technology to enhance pleasure. ...

Controlled release of aldicarb from lignin loaded ionotropic hydrogel microspheres [Koks Group]Controlled release of aldicarb from lignin loaded ionotropic hydrogel microspheres [Kok's Group]
Kök FN, Wilkins RM, Cain RB, Arica MY, Alaeddinoğlu G, Hasirci V. Department of Biological Sciences, Middle East Technical University, Ankara, Turkey. Aldicarb loaded microspheres of carboxymethyl cellulose, CMC, of various compositions were prepared with the crosslinking action of Al(III). Into these microspheres, lignin was introduced as a filler to further regulate the rate of release. The encapsulation efficiency was low (4.15-13.00%) due to the high water solubility of aldicarb. Release into aqueous media was quite rapid and almost complete within 24h. Initial stages of the release (60% of AS released) was investigated to determine the release mechanism and it was found that release from the microspheres was governed by Fickian diffusion. Among the various parameters, the ratio of lignin to CMC and aldicarb to CMC were found to be influential on the rate of release from the crosslinked CMC-lignin microspheres. The soil behaviour confirmed the delayed release effect of the controlled ...
INVESTIGATION OF THE SUITABILITY OF COLLOIDAL PARTICLES FOR USE AS HYDROLOGICAL TRACERSINVESTIGATION OF THE SUITABILITY OF COLLOIDAL PARTICLES FOR USE AS HYDROLOGICAL TRACERS
Sand column experiments were conducted to investigate the efficacy of colloidal particles (microspheres) as hydrological tracers. Two main questions were investigated: 1. What is the relationship between breakthrough volume and column height for latex microspheres in a sand column? 2. Is the fraction of latex microspheres filtered out by sand a function of column length? Small-scale sand column experiments were carried out under both saturated and unsaturated conditions. Carboxylated latex microspheres were used as test-tracers. The pore volume of water that flows out of the column before the microspheres breakthrough was linearly related to column height in all trials. The fraction of latex microspheres filtered out by the sand column was not a function of column height unless the water is salty. In one set of unsaturated experiments using 10 mM of NaCl solution, the fraction of microspheres retained in the sand column was linearly related to column height. As this was a only a proof-of-concept ...

N2 - Distribution of bronchial blood flow was measured in unanesthetized sheep by the use of two modifications of the microsphere reference sample technique that correct for peripheral shunting of microspheres: 1) A double microsphere method in which simultaneous left and right atrial injections of 15μm microspheres tagged with different isotopes allowed measurement of both pulmonary blood flow and shunt-corrected bronchial blood flow, and 2) a pulmonary arterial occlusion method in which left atrial injection and transient occlusion of the left pulmonary artery prevented delivery to the lung of microspheres shunted through the peripheral circulation and allowed systemic blood flow to the left lung to be measured. Both methods can be performed in unanesthetized ...
Directed TherapyDirected Therapy
What is Selective Internal Radiation Therapy?. SIRT is a revolutionary treatment for cancers of the liver that uses new technology to deliver radiation directly to the site of the tumor. SIRT delivers millions of microscopic radioactive spheres, called SIR-Spheres or Therasphere, directly to the site of the liver tumors, where they selectively irradiate the tumors. The targeted nature of SIRT lets doctors deliver up to 40 times more radiation to the liver tumors than would be possible using conventional radiotherapy.. What to expect before, during, and after treatment. Selective Internal Radiation Therapy is known by a number of names that include: SIRT, Sir-spheres, Therasphere, radioembolization, Yttrium 90, Y90, brachytherapy, and has been coined by YES co-founder as little magic beads. We understand that being diagnosed with liver cancer or metastases to the liver from other cancer is terrifying, to say the least. Exploring the treatment options available and choosing the one best suited ...

Urea formaldehyde (UF) resins are important for wood industry due to their attractive properties at reasonable price. Particulate fillers added to UF are of interest with regard to improving the functionality of UF and also in terms of reduced UF consumption. To study their potential as filler, solid UF microspheres were synthesized and characterised respecting its morphology, chemical curing and thermal stability. Marigold flower structured spheres with diameters between 5 and 20 µm are presented and application trials demonstrated that high amounts of UF may be replaced by solid microspheres without impairing adhesive bond strength of solid wood bond lines. Fluorescence microscopy showed that microspheres greatly reduce adhesive penetration into the wood substrate, retaining the modified adhesive in the bondline. UF microspheres may thus be considered as viable filler for UF adhesives, particularly with regard to the possibility of endowing them with added functionality like self-healing properties.

Rivastigmine tartrate is an anticholine esterase inhibitor that used in the treatment of Alzheimers disease. In this study an attempt was made to encapsulate the Rivastigmine tartrate in sodium alginate microspheres for controlled delivery of it. Microspheres were prepared by the emulsion cross linking method were Glutaraldehyde saturated toluene (GST) was used as a cross linker. Total four batches were prepared with different amount of Glutaraldehyde. It was found that GST had no significant effect on % yield, also increase in amount of GST decrease the particle size and increases the entrapment. GST had shown significant effect on the in vitro drug release and found that increase in amount of GST prolongs the drug release from 36 to 96 hrs. Microspheres shown to be follow the Higuchi model.

Background. Stem cell therapy to improve cardiac function after myocardial infarction is hampered by poor cell retention, while it may also increase the risk of arrhythmias by providing an arrhythmogenic substrate. We previously showed that porcine adipose tissue-derived-stromal cells (pASC) induce conduction slowing through paracrine actions, whereas rat ASC (rASC) and human ASC (hASC) induce conduction slowing by direct coupling. We postulate that biomaterial microspheres mitigate the conduction slowing influence of pASC by interacting with paracrine signaling.. Aim. To investigate the modulation of ASC-loaded recombinant human collagen-based microspheres, on the electrophysiological behavior of neonatal rat ventricular myocytes (NRVM).. Method. Unipolar extracellular electrograms, derived from microelectrode arrays (8x8 electrodes) containing NRVM, co-cultured with ASC or ASC loaded microspheres, were used to determine conduction velocity (CV) and conduction heterogeneity.

OSA | Room temperature lasing of InAs/GaAs quantum dots in the whispering gallery modes of a silica microsphereOSA | Room temperature lasing of InAs/GaAs quantum dots in the whispering gallery modes of a silica microsphere
We have achieved low threshold lasing of self-assembled InAs/GaAs quantum dots coupled to the evanescent wave of the high-Q whispering gallery modes of a silica microsphere. In spite of high temperature and Q-spoiling of whispering gallery modes due to diffusion and refraction on the high index semiconductor sample, room temperature lasing is obtained with less than 100 quantum dots. This result highlights the feasibility and interest of combining self-assembled quantum dots and microspheres in view of cavity-quantum electrodynamics experiments.. ©2007 Optical Society of America.

Effect of collagen peptides-carboxymethyl chitosan microspheres o...: Ingenta ConnectEffect of collagen peptides-carboxymethyl chitosan microspheres o...: Ingenta Connect
Type I collagen peptides were prepared by hydrolysis of type I collagen protein with different enzyme combinations and this study found that the peptides obtained by papain/pepsin/trypsin combination hydrolysis were of the strongest anti-X-ray capability. The collagen peptides-carboxymethyl chitosan (CP-CMC-CaCl2) microspheres were prepared by emulsification method and used to investigate the effects on mice skin damages in vitro and in vivo. In vitro experiments indicated that the CP-CMC-CaCl2 microspheres had a protective effect on the X-ray irradiated damages of mice thymus lymphocytes. The mice skin surface texture morphological and histomorphological analysis showed a consistent result that the CP-CMC-CaCl2 microspheres played a certain role in the prevention of UV-B irradiated skin damages and could also improve ultraviolet prevention ability. Besides, the preventive function was better than its repair function. It is possible to improve the preventive function to skin photoaging and play ...

TY - JOUR. T1 - Microsphere passage through intestinal circulation. T2 - via shunts or capillaries?. AU - Maxwell, L. C.. AU - Shepherd, A. P.. AU - McMahan, C. A.. PY - 1985/2. Y1 - 1985/2. N2 - Significant quantities of 9-micron microspheres (20-30%) are not trapped in the intestine following intracardiac or intra-arterial injection, but reach venous blood. Some investigators propose that the passage of 9-micron spheres measures blood flow through noncapillary connections. Because frequency distributions of intestinal capillary diameters and 9-micron spheres overlap, microspheres could simply pass through capillaries. Therefore, we developed simple probabilistic models to predict both the size distribution and the percentage of injected spheres [9 +/- 1 (SD) micron] that should appear in venous blood. Chief assumptions in models are that microsphere delivery and sphere diameter are independent and that microspheres pass through capillaries of equal or larger size. The passage predicted by the ...
Synthesis of SAPO-11 Molecular Sieve Microspheres Using a Microwave Technique and Mediated by Ionic MicellesSynthesis of SAPO-11 Molecular Sieve Microspheres Using a Microwave Technique and Mediated by Ionic Micelles
Abstract: Micelles formed by cetyltrimethylammoniumchlorine (CTAC) and n-butanol were used as shape-directing templates to synthesize SAPO-11 molecular sieve microspheres by a microwave technique. Effects of CTAC concentration, time of crystallization, and dosage of HF were investigated. Properties of the products were characterized systematically by X-ray powder diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), thermal analysis (TG-DTA), electron diffraction spectroscopy (EDS) and N2 physisorption. When c(CTAC)+c(n-butanol)=0.180 mol·L-1, SAPO-11 molecular sieve microspheres with the preferred crystallinity were obtained. The crystallinity of the synthesized SAPO-11 molecular sieve microspheres was improved by prolonging the reaction time. The substitution of Si species and the crystallization of SAPO-11 molecular sieve microspheres were also improved by appropriate usage of HF. Using control experiments, the reaction mechanism for the ...
A new model of subretinal neovascularization in the rabbit. | IOVS | ARVO JournalsA new model of subretinal neovascularization in the rabbit. | IOVS | ARVO Journals
PURPOSE: To establish a new model of subretinal neovascularization (SRN) in the rabbit by implanting basic fibroblast growth factor (bFGF)-impregnated gelatin microspheres beneath the retina. METHODS: Basic fibroblast growth factor-impregnated gelatin microspheres were prepared by forming a polyion complex between gelatin and bFGF. The microspheres, containing 2.5 micrograms of bFGF, were injected into the subretinal space of rabbit eyes (n = 29). Control eyes (n = 10) received bFGF-free gelatin microspheres. Eyes were followed up for 3 days to 8 weeks by ophthalmoscopy, photography, fluorescein angiography, light microscopy, and transmission electron microscopy. RESULTS: Twenty of 24 experimental eyes (83%) showed fluorescein leakage from SRN 2 weeks after implantation of the bFGF-impregnated microspheres. This leakage continued for 2 to 6 more weeks. In striking contrast, control eyes showed no fluorescein leakage. Histologic examination revealed SRN in all the experimental eyes but in none of ...
Differentiation of Mouse Embryonic Stem Cells Using PEG-Fibrinogen Hydrogel MicrospheresDifferentiation of Mouse Embryonic Stem Cells Using PEG-Fibrinogen Hydrogel Microspheres
Cardiac disease is the leading cause of death worldwide, and current treatments are either ineffective at significantly prolonging lifespan or are unavailable to the majority of patients in need due to a lack of supply. Application of engineered heart tissue is a promising method to repair damaged hearts, but there are many challenges to generate functional cardiac tissue which can integrate with damaged myocardium. We have developed a highly scalable method for producing cardiac tissue from mouse embryonic stem cells (mESCs) using poly(ethylene glycol)-diacrylate (PEGDA) based hydrogels with a conjugated fibrinogen protein functional motif. Hydrogels consisted of dispersed microsphere cell-carriers to be utilized as in vitro differentiation systems or as a possible injectable delivery vehicle. Cells were encapsulated within the hydrogel polymer precursor and microspheres were generated via water-in-oil emulsification. The generation of microspheres with reproducible diameter distributions ...

DOUBLE-WALLED METAL CLARINETSDOUBLE-WALLED METAL CLARINETS
Historical Overview: Conn began producing a double-walled metal clarinet just a few years after the first saxophone was made in America (1888). Couesnon presented a double-walled Boehm System clarinet in a Paris Exposition in 1900. Triebert also came out with a copy of the Couesnon. Around 1910 Penzel-Mueller (NY) started making the double-walled Clari-Met line to be offered at a price of $150-$200, and was perhaps the most expensive clarinet available at the time. According to the manufacturer, the Clari-Met, made of a special alloy that was almost sterling was destined to make wooden clarinets obsolete. By the mid 1920s there was little interest in the very complicated manufacturing process to produce a clarinet that cost half as much as an automobile. Then in the late 20s Conn began making the "Armored clarinet, a double-walled model filled with hard rubber. And finally Haynes started producing a double-walled sterling clarinet which is said to have caused heated debate within the company, ...

Interpretive Summary: Technical Abstract: Nutrim-10 is a newly developed food product containing the dietary of soluble fiber ß-glucan. The micro-structural heterogeneities of Nutrim-10 suspensions were investigated by monitoring the thermally driven displacements of well-dispersed microspheres via video fluorescence microscopy. By comparing the distribution of the time-dependent mean-square displacement (MSD) of polystyrene microspheres embedded in three concentrations of Nutrim-10 suspensions, we found that the degree of heterogeneity of the suspensions increased dramatically within a narrow range of Nutrim-10 concentrations. The ensemble-averaged MSD of 5.5% Nutrim-10 suspension exhibited a power-law behavior which scaled linearly with time. This behavior was similar to that of homogeneous ...
