Receptor-mediated targeting of fluorescent probes in living cells. (1/933)

A strategy was developed to label specified sites in living cells with a wide selection of fluorescent or other probes and applied to study pH regulation in Golgi. cDNA transfection was used to target a single-chain antibody to a specified site such as an organelle lumen. The targeted antibody functioned as a high affinity receptor to trap cell-permeable hapten-fluorophore conjugates. Synthesized conjugates of a hapten (4-ethoxymethylene-2-phenyl-2-oxazolin-5-one, phOx) and fluorescent probes (Bodipy Fl, tetramethylrhodamine, fluorescein) were bound with high affinity (approximately 5 nM) and specific localization to the single-chain antibody expressed in the endoplasmic reticulum, Golgi, and plasma membrane of living Chinese hamster ovary cells. Using the pH-sensitive phOx-fluorescein conjugate and ratio imaging microscopy, pH was measured in the lumen of Golgi (pH 6.25 +/- 0.06). Measurements of pH-dependent vacuolar H+/ATPase pump activity and H+ leak in Golgi provided direct evidence that resting Golgi pH is determined by balanced leak-pump kinetics rather than the inability of the H+/ATPase to pump against an electrochemical gradient. Like expression of the green fluorescent protein, the receptor-mediated fluorophore targeting approach permits specific intracellular fluorescence labeling. A significant advantage of the new approach is the ability to target chemical probes with custom-designed spectral and indicator properties.  (+info)

Endocytic sorting of lipid analogues differing solely in the chemistry of their hydrophobic tails. (2/933)

To understand the mechanisms for endocytic sorting of lipids, we investigated the trafficking of three lipid-mimetic dialkylindocarbocyanine (DiI) derivatives, DiIC16(3) (1,1'-dihexadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate), DiIC12(3) (1,1'- didodecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate), and FAST DiI (1,1'-dilinoleyl-3,3,3', 3'-tetramethylindocarbocyanine perchlorate), in CHO cells by quantitative fluorescence microscopy. All three DiIs have the same head group, but differ in their alkyl tail length or unsaturation; these differences are expected to affect their distribution in membrane domains of varying fluidity or curvature. All three DiIs initially enter sorting endosomes containing endocytosed transferrin. DiIC16(3), with two long 16-carbon saturated tails is then delivered to late endosomes, whereas FAST DiI, with two cis double bonds in each tail, and DiIC12(3), with saturated but shorter (12-carbon) tails, are mainly found in the endocytic recycling compartment. We also find that DiOC16(3) (3,3'- dihexadecyloxacarbocyanine perchlorate) and FAST DiO (3, 3'-dilinoleyloxacarbocyanine perchlorate) behave similarly to their DiI counterparts. Furthermore, whereas a phosphatidylcholine analogue with a BODIPY (4,4-difluoro-4-bora-3a,4a-diaza-s-indacene) fluorophore attached at the end of a 5-carbon acyl chain is delivered efficiently to the endocytic recycling compartment, a significant fraction of another derivative with BODIPY attached to a 12-carbon acyl chain entered late endosomes. Our results thus suggest that endocytic organelles can sort membrane components efficiently based on their preference for association with domains of varying characteristics.  (+info)

Orientation of the pore-forming peptide GALA in POPC vesicles determined by a BODIPY-avidin/biotin binding assay. (3/933)

We determined the orientation of a biotinylated version of the pore-forming peptide GALA (WEAALAEALAEALAEHLAEALAEALEALAA) at pH 5.0 in large unilamellar phosphatidylcholine vesicles, using the enhancement of BODIPY-avidin fluorescence subsequent to its irreversible binding to a biotin moiety. GALA and its variants were biotinylated at the N- or C-terminus. BODIPY-avidin was either added externally or was pre-encapsulated in vesicles to assess the fraction of liposome-bound biotinylated GALA that exposed its labeled terminus to the external or internal side of the bilayer, respectively. Under conditions where most of the membrane-bound peptides were involved in transmembrane aggregates and formed aqueous pores (at a lipid/bound peptide molar ratio of 2500/1), the head-to-tail (N- to C-terminus) orientation of the membrane-inserted peptides was such that 3/4 of the peptides exposed their N-terminus on the inside of the vesicle and their C-terminus on the outside. Under conditions resulting in reduced pore formation (at higher lipid/peptide molar ratios), we observed an increase in the fraction of GALA termini exposed to the outside of the vesicle. These results are consistent with a model (Parente et al., Biochemistry, 29:8720, 1990) that requires a critical number of peptides (M) in an aggregate to form a transbilayer structure. When the peptides form an aggregate of size i, with i < M = 4 to 6, the orientation of the peptides is mostly parallel to the membrane surface, such that both termini of the biotinylated peptide are exposed to external BODIPY-avidin. This BODIPY-avidin/biotin binding assay should be useful to determine the orientation of other membrane-interacting molecules.  (+info)

Synthesis of 5-substituted 2'-deoxycytidine 5'-(alpha-P-borano)triphosphates, their incorporationinto DNA and effects on exonuclease. (4/933)

Direct PCR sequencing with boronated nucleotides provides an alternative to current PCR sequencing methods. The positions of boranophosphate-modified nucleotides incorporated randomly into DNA during PCR can be revealed directly by exonuclease digestion to give sequencing ladders. Cytosine nucleotides, however, are especially sensitive to exonuclease digestion and provide suboptimal sequencing ladders. Therefore, a series of 5-substituted analogs of 2'-deoxycytidine 5'-(alpha-P-borano)triphosphates (dCTPalphaB) were synthesized with the hope of increasing the nuclease resistance of deoxycytosine residues and thereby enhancing the deoxycytosine band intensities. These dCTP analogs contain a boranophosphate modification at the alpha-phosphate group in 2'-deoxycytidine 5'-triphosphate (dCTP) as well as a 5-methyl, 5-ethyl, 5-bromo or 5-iodo substitution for the 5-hydrogen of cytosine. The two diastereomers of each new dCTP derivative were separated by reverse phase HPLC. The first eluted diastereomer (putatively Rp) of each dCTP analog was a substrate for T7 DNA polymerase (Sequenase) and had an incorporation efficiency similar to normal dCTP and dCTPalphaB, with the 5-iodo-dCTPalphaB analog being the least efficient. Substitution at the C-5 position of cytosine by alkyl groups (ethyl and methyl) markedly enhanced the dCTPalphaB resistance towards exonuclease III (5-Et-dCTPalphaB >5-Me-dCTPalphaB >dCTPalphaB approximately 5-Br-dCTPalphaB >5-I-dCTPalphaB), thereby generating DNA sequences that better define the deoxycytosine positions. The introduction of modified dCTPalphaB should increase the utility of direct DNA sequencing with boronated nucleoside 5'-triphosphates.  (+info)

Tamoxifen inhibits acidification in cells independent of the estrogen receptor. (5/933)

Tamoxifen has been reported to have numerous physiological effects that are independent of the estrogen receptor, including sensitization of resistant tumor cells to many chemotherapeutic agents. Drug-resistant cells sequester weak base chemotherapeutics in acidic organelles away from their sites of action in the cytosol and nucleus. This work reports that tamoxifen causes redistribution of weak base chemotherapeutics from acidic organelles to the nucleus in drug-resistant cells. Agents that disrupt organelle acidification (e.g., monensin, bafilomycin A1) cause a similar redistribution. Measurement of cellular pH in several cell lines reveals that tamoxifen inhibits acidification of endosomes and lysosomes without affecting cytoplasmic pH. Similar to monensin, tamoxifen decreased the rate of vesicular transport though the recycling and secretory pathways. Organellar acidification is required for many cellular functions, and its disruption could account for many of the side effects of tamoxifen.  (+info)

BOCILLIN FL, a sensitive and commercially available reagent for detection of penicillin-binding proteins. (6/933)

We describe a new, sensitive, rapid, and nonradioactive method involving the use of the commercially available BOCILLIN FL, a fluorescent penicillin, as a labeling reagent for the detection and study of penicillin-binding proteins (PBPs). This method allowed rapid detection of 30 ng of a purified PBP protein under UV light and of 2 to 4 ng of the protein with the aid of a FluorImager. This method also allowed rapid determination of the PBP profiles of Escherichia coli, Pseudomonas aeruginosa, and Streptococcus pneumoniae. The PBP profiles obtained are virtually identical to those reported previously with 3H-, 14C-, or 125I-labeled penicillin. Using this method enabled us to determine the 50% inhibitory concentrations of the penicillin-sensitive and -resistant PBP2x proteins of S. pneumoniae for penicillin G, thereby allowing a direct evaluation of their relative affinities for penicillin G. Finally, this method also allowed us to compare relative affinities of a PBP2x protein for different beta-lactam antibiotics with the aid of fluorescence polarization technology and to monitor a PBP2x protein during purification.  (+info)

cAMP-dependent mobilization of intracellular Ca2+ stores by activation of ryanodine receptors in pancreatic beta-cells. A Ca2+ signaling system stimulated by the insulinotropic hormone glucagon-like peptide-1-(7-37). (7/933)

Glucagon-like peptide-1 (GLP-1) is an intestinally derived insulinotropic hormone currently under investigation for use as a novel therapeutic agent in the treatment of type 2 diabetes mellitus. In vitro studies of pancreatic islets of Langerhans demonstrated that GLP-1 interacts with specific beta-cell G protein-coupled receptors, thereby facilitating insulin exocytosis by raising intracellular levels of cAMP and Ca2+. Here we report that the stimulatory influence of GLP-1 on Ca2+ signaling results, in part, from cAMP-dependent mobilization of ryanodine-sensitive Ca2+ stores. Studies of human, rat, and mouse beta-cells demonstrate that the binding of a fluorescent derivative of ryanodine (BODIPY FL-X ryanodine) to its receptors is specific, reversible, and of high affinity. Rat islets and BTC3 insulinoma cells are shown by reverse transcriptase polymerase chain reaction analyses to express mRNA corresponding to the type 2 isoform of ryanodine receptor-intracellular Ca2+ release channel (RYR2). Single-cell measurements of [Ca2+]i using primary cultures of rat and human beta-cells indicate that GLP-1 facilitates Ca2+-induced Ca2+ release (CICR), whereby mobilization of Ca2+ stores is triggered by influx of Ca2+ through L-type Ca2+ channels. In these cells, GLP-1 is shown to interact with metabolism of D-glucose to produce a fast transient increase of [Ca2+]i. This effect is reproduced by 8-Br-cAMP, but is blocked by a GLP-1 receptor antagonist (exendin-(9-39)), a cAMP antagonist ((Rp)-cAMPS), an L-type Ca2+ channel antagonist (nimodipine), an antagonist of the sarco(endo)plasmic reticulum Ca2+ ATPase (thapsigargin), or by ryanodine. Characterization of the CICR mechanism by voltage clamp analysis also demonstrates a stimulation of Ca2+ release by caffeine. These findings provide new support for a model of beta-cell signal transduction whereby GLP-1 promotes CICR by sensitizing intracellular Ca2+ release channels to the stimulatory influence of cytosolic Ca2+.  (+info)

Interaction of diphtheria toxin T domain with molten globule-like proteins and its implications for translocation. (8/933)

The transmembrane (T) domain of diphtheria toxin has a critical role in the low pH-induced translocation of the catalytic domain (A chain) of the toxin across membranes. Here it is shown that at low pH, addition of proteins in a partly unfolded, molten globule-like conformation converted the T domain from a shallow membrane-inserted form to its transmembrane form. Fluorescence energy transfer demonstrated that molten globule-like proteins bound to the T domain. Thus, the T domain recognizes proteins that are partly unfolded and may function in translocation of the A chain as a transmembrane chaperone.  (+info)

2-Aminoethoxydiphenyl borate - Wikipedia2-Aminoethoxydiphenyl borate - Wikipedia
2-Aminoethoxydiphenyl borate (2-APB) is a chemical that acts to inhibit both IP3 receptors[1] and TRP channels (although it activates TRPV1, TRPV2, & TRPV3 at higher concentrations).[2][3] In research it is used to manipulate intracellular release of calcium ions (Ca2+) and modify TRP channel activity, although the lack of specific effects make it less than ideal under some circumstances. Additionally, there is evidence that 2-APB acts directly to inhibit gap junctions made of connexin.[4] Increasing evidence showed that 2-APB is a powerful modifier of store-operated calcium channels (SOC) function, low concentration of 2-APB can enhance SOC while high concentration induces a transient increase followed by complete inhibition.[5][6][7] ...

Fluorescent ligands for the A3 adenosine receptor.Fluorescent ligands for the A3 adenosine receptor.
Fluorescent probes are useful tools to investigate specific subcellular components in cells, tissues and organisms. A classic application of fluorescent ligands of a specific GPCR (G-protein coupled receptors) is the investigation of the receptor location, and, if their binding is reversible, it could provide pharmacological information such as affinity and proximity between interacting molecules. In cultured cell systems, methods based on fluorescence have permitted to observe the receptor cycling and the formation of oligomeric receptor complexes. In high throughput screening, fluorescent ligands represents a safer, more powerful and more versatile alternative to radioligands. [1] The introduction of the bulky fluorophore into a small molecule ligand could lead to deep modifications not only from a physicochemical point of view but also in its pharmacological properties. [2] In order to allow a correct interaction of the pharmacophore with its receptor, it is usually separated from the ...

Creating a New Fluorescent Dye | Minnesota Supercomputing InstituteCreating a New Fluorescent Dye | Minnesota Supercomputing Institute
Fluorescent chromophores are compounds that can emit light under certain circumstances. They are useful to chemists as dyes or markers, and can be used for such applications as medical and biological imaging.. In a recent paper that appeared in the Journal of the American Chemical Society, Professor Victor Nemykin (Chemistry and Biochemistry, University of Minnesota Duluth) and his collaborators at the University of Akron (Akron, Ohio) discuss a new fluorescent chromophore, or fluorophore, called BOPHY. (BOPHY stands for bis(difluoroboron)1,2-bis(1H-pyrrol-2-yl)methylene)hydrazine.) This compound is related to a very successful class of fluorophores already in use, the boron dipyrromethene family of compounds. BOPHY is important because it can be produced with a simple two-step procedure, and it is highly fluorescent.. The researchers studied two compounds, the BOPHY chromophore and a tetrameythyl-substituted BOPHY analogue called Me4BOPHY. They investigated the absorption and emissions spectra ...

Characterization of the Boron Doping Process UsingBoron Nitride Solid Source DiffusionThe purpose of this research has been to develop an optimum process for the borondoping of implants and polysilicon gates of metal-oxide-semiconductor (MOS) devices.An experimental design was constructed to determine the effects of diffusiontemperature, time, and ambient on characteristics of the doping process. A temperaturerange of 800 to 1000 degrees Celsius was studied with a diffusion time between 10 and60 minutes. Two diffusion ambients were used for doping processes, a pure nitrogenambient and a nitrogen-oxygen gaseous mixture. Device wafers were fabricated, and thetesting of MOS capacitors and van der Pauw test structures was performed to determinethe effect of diffusion conditions on flatband voltage and poly gate doping. Materialscharacterization techniques were used on monitor wafers for each diffusion process todetermine the wafer structure formed for each process and ...

2-APB was initially shown to be an antagonist for IP3 receptors, blocking IP3-induced calcium release in cerebellar microsomes with an IC50 of 42 μM (Maruyama et al., 1997) and blocking the IP3 receptor in intact cells at 75 μM (Ma et al., 2000). More recent studies have shown that 2-APB is an even more potent blocker for store-operated calcium entry than for IP3-induced calcium release (for review, see Bootman et al., 2002). Moreover, 2-APB at 100 μM concentrations has been found to block volume-regulated anion channels (Lemonnier et al., 2004), to cause mitochondrial swelling (Peppiatt et al., 2003), and to activate calcium permeable cation channels (Braun et al., 2003). In addition, 2-APB was recently reported to exert opposite effects on members of the TRP gene family, decreasing activity of TRP5 and TRP6 at 20 μM (Xu et al., 2005) and activating TRPV1, TRPV2, and TRPV3 at higher concentrations (Hu et al., 2004).. A recent study revealed an unexpected inhibitory action of 2-APB on gap ...

In the present study we show that 2-APB is an efficient inhibitor of Drosophila phototransduction, operating both in intact cells and in isolated ommatidia, and that this inhibition partially reverses when the inhibitor is removed. The great interest in 2-APB arises from its reported function as a powerful probe for assessing involvement of InsP3 receptors in cell signaling (Maruyama et al., 1997; Ma et al., 2000). Indeed, the reversible inhibition of InsP3-induced current oscillations in Xenopus oocytes strongly supports previous studies showing that 2-APB blocks Ca2+ release from InsP3-sensitive Ca2+ stores (Maruyama et al., 1997). Furthermore, the failure of 2-APB to block the Ca2+-activated surface membrane Cl− channels while it suppresses the InsP3-induced activity indicates that the action of 2-APB is confined to the signaling stages downstream of InsP3 production, but upstream of the Ca2+ release-activated processes.. The inhibitory effect of 2-APB on ICl,Ca-induced by Ca2+ store ...

Boron nitride aerogel - WikipediaBoron nitride aerogel - Wikipedia
Boron nitride aerogel is an aerogel made of highly porous boron nitride (BN). It typically consists of a mixture of deformed boron nitride nanotubes and nanosheets. It can have a density as low as 0.6 mg/cm3 and a specific surface area as high as 1050 m2/g, and therefore has potential applications as an absorbent, catalyst support and gas storage medium. BN aerogels are highly hydrophobic and can absorb up to 160 times their mass in oil. They are resistant to oxidation in air at temperatures up to 1200 °C, and hence can be reused after the absorbed oil is burned out by flame. BN aerogels can be prepared by template-assisted chemical vapor deposition at a temperature ~900 °C using borazine as the feed gas. Alternatively it can be produced by ball milling h-BN powder, ultrasonically dispersing it in water, and freeze-drying the dispersion.

Boron Nitride Nanotubes functionalized with glucosamine as a potential novel carrier system for radioisotope and drug deliveryBoron Nitride Nanotubes functionalized with glucosamine as a potential novel carrier system for radioisotope and drug delivery
In the present work, Boron nitride nanotubes (BNNTs) were synthesized and submitted to a functionalization process (coating) with glucosamine. The nanostructures were physicochemical and morphologically characterized by Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), Raman Spectroscopy and Photon Correlation Spectroscopy (PCS). Furthermore, in vitro tests were conducted to evaluate the cytocompatibility of the nanostructures. The results revealed that nanotubes presented size, polydispersity index and Zeta potential adequate to applied in vivo studies. The cytocompatibility test were conducted in normal MRC-5 fibroblast lung cells, through MTT and DAPI assays. The results revealed, in tested concentrations (0.1; 10; 50; 100; 200 µ/mL), that BNNTs no presented a cytotoxic profile and negligible DNA changes. Considering the results obtained, the BNNTs showed adequate characteristic to be applied as novel carrier system for radioisotope and drug delivery.

Functionalized Boron Nitride Nanotubes - Energy Innovation PortalFunctionalized Boron Nitride Nanotubes - Energy Innovation Portal
A plasma treatment has been used to modify the surface of BNNTs. In one example, the surface of the BNNT has been modified using ammonia plasma to include amine functional groups. Amine functionalization allows BNNTs to be soluble in chloroform, which had not been possible previously. Further functionalization of amine-functionalized BNNTs with thiol-terminated organic molecules has also been demonstrated. Gold nanoparticles have been self-assembled at the surface of both amine- and thiol-functionalized boron nitride Nanotubes (BNNTs) in solution. This approach constitutes a basis for the preparation of highly functionalized BNNTs and for their utilization as nanoscale templates for assembly and integration with other nanoscale materials.

In the present work, based on extensive fully atomistic molecular dynamics simulations, we discuss the dynamics of neon atoms oscillating inside (5,5) single-walled carbon nanotubes (CNTs) and boron nitride nanotubes (BNNTs). Our results show that sustained high-frequency oscillatory regimes are possible for a large range of temperatures. Our results also show that the general features of the oscillations are quite similar to those observed in CNT and BNNT, in contrast with some speculations in previous works in the literature about the importance of broken symmetry and chirality exhibited by BNNTs ...

Armchair Boron Nitride nanotubes-heterocyclic molecules interactions: A computational descriptionArmchair Boron Nitride nanotubes-heterocyclic molecules interactions: A computational description
|p|Ab-initio calculations using density functional theory (DFT) are used to investigate the non-covalent interactions between single wall armchair boron nitride nanotubes (BNNTs) with open ends and several heterocyclic molecules: thiophene (T; C|sub|4|/sub|H|sub|4|/sub|S), benzothiophene (BT; C8H6S) and dibenzothiophene (DBT; C|sub|12|/sub|H|sub|8|/sub|S). In the armchair model the nanotubes exhibit (n, n) chirality; here we consider n = 5. The exchange-correlation energies are treated according to the Hamprecht-Cohen-Tozer-Handy functional in the generalized gradient approximation (HCTH-GGA). A base function with double polarization is used. The geometry optimization of (5,5) BNNT-X; X = T, BT and DBT has been carried out using the minimum energy criterion in 5 different configurations of the molecules adsorbed on the nanotube. Our computer simulations have found that the preferential adsorption site of the molecule on the nanotube surface is the parallel configuration for BT and DBT, and at one

A process for growing an electrically conductive metalloid thin film on a substrate with a chemical vapor deposition process. A metal source material and a reducing agent capable of reducing the metal source material to a reduced state are vaporized and fed into a reaction space, where the metal source material and the reducing agent are contacted with the substrate. The reducing agent is a boron compound having at least one boron-carbon bond, and the boron compound forms gaseous by-products when reacted with the metal source material. Generally, the boron compound is an alkylboron compound with 0-3 halogen groups attached to the boron. The metal source material and the reducing agent may be fed continuously or in pulses during the deposition process.

In this study, magnesium composites with nano-size boron nitride (BN) particulates of varying contents were synthesized using the powder metallurgy (PM) technique incorporating microwave-assisted two-directional sintering followed by hot extrusion. The effect of nano-BN addition on the microstructural and the mechanical behavior of the developed Mg/BN composites were studied in comparison with pure Mg using the structure-property correlation. Microstructural characterization revealed uniform distribution of nano-BN particulates and marginal grain refinement. The coefficient of thermal expansion (CTE) value of the magnesium matrix was improved with the addition of nano-sized BN particulates. The results of XRD studies indicate basal texture weakening with an increase in nano-BN addition. The composites showed improved mechanical properties measured under micro-indentation, tension and compression loading. While the tensile yield strength improvement was marginal, a significant increase in compressive

Boron-containing polymer has electric vehicle energy storage potential | The Engineer The EngineerBoron-containing polymer has electric vehicle energy storage potential | The Engineer The Engineer
Generally, high-temperature applications require ceramic dielectrics, but these are heavy and brittle, according to Penn State professor of materials science and engineering, Qing Wang, who led the research. Polymer dielectrics are lighter, but have tended to degrade in performance or melt at high temperatures, necessitating a cooling system, which adds further weight and complexity.. Wang and his team used boron nitride, a two-dimensional substance similar in structure to graphene which has been shown to have dielectric properties, in the form of nanosheets about 2nm thick and 400nm across as the active agent in a cross-linked polymer nanocomposite with benzenecyclobutene, a polymer used in electronics. The composite can be made by just mixing the boron nitride and the polymer precursor, then curing with heat or light to create the cross-linked structure. Because the nanosheets are so small, the polymer remains flexible. The team claims in a paper in Nature that the polymer can be ...

Boron - Infogalactic: the planetary knowledge coreBoron - Infogalactic: the planetary knowledge core
Boron is needed by life. In 2013, a hypothesis suggested it was possible that boron and molybdenum catalyzed the production of RNA on Mars with life being transported to Earth via a meteorite around 3 billion years ago.[115]. There exists one known boron-containing natural antibiotic, boromycin, isolated from streptomyces.[116][117]. Boron is an essential plant nutrient, required primarily for maintaining the integrity of cell walls. However, high soil concentrations of , 1.0 ppm lead to marginal and tip necrosis in leaves as well as poor overall growth performance. Levels as low as 0.8 ppm produce these same symptoms in plants that are particularly sensitive to boron in the soil. Nearly all plants, even those somewhat tolerant of soil boron, will show at least some symptoms of boron toxicity when soil boron content is greater than 1.8 ppm. When this content exceeds 2.0 ppm, few plants will perform well and some may not survive. When boron levels in plant tissue exceed 200 ppm, symptoms of boron ...

Artificial Light-Harvesting Arrays: Electronic Energy Migration and Trapping on a Sphere and between Spheres A sophisticated model of the natural light-harvesting antenna has been devised by decorating a C60 hexa-adduct with ten yellow and two blue boron dipyrromethene (Bodipy) dyes in such a way that the dyes retain their individuality and assist solubility of the fullerene. Unusually, the fullerene core is a poor electron acceptor and does not enter into light-induced electron-transfer reactions with the appended dyes, but ineffective electronic energy transfer from the excited-state dye to the C60 residue competes with fluorescence from the yellow dye. Intraparticle electronic energy transfer from yellow to blue dyes can be followed by steady-state and time-resolved fluorescence spectroscopy and by excitation spectra for isolated C60 nanoparticles dissolved in dioxane at 293 K and at 77 K.

Harder than Diamond - TFOTHarder than Diamond - TFOT
This discovery may eventually lead to new superstrong materials. However, both wurtzite boron nitride and lonsdaleite are difficult to synthesize in large quantities, so practical applications using these stronger materials are not yet feasible (methods for synthesizing nanocomposites containing lonsdaleite and wurtzite boron nitride are under development to assist in further research). In addition, many practical uses of hard materials require other qualities such as thermal stability at high temperatures. Conductivity, superconductivity, and magnetism are also desirable qualities for many applications of superstrong materials. The pressurized wurtzite boron nitride and lonsdaleite may or may not meet these other requirements. ...

Paul Preuss fiction & science » Core and The Core: Why Not Brazzletonite?Paul Preuss fiction & science » Core and The Core: Why Not Brazzletonite?
In 1947, while teaching a graduate course in physics at the University of Chicago, Enrico Fermi famously posed the question, What is the deepest hole that may be dug into the Earth? Since it was an experiment that had never been done, he didnt have the answer, but it sure got the students thinking.. The first thing youd need is a material that can penetrate the very hard, very high-pressure, very hot deepest mantle. In the movie The Core, an ingenious inventor, Edward Brazzleton (played by Delroy Lindo), comes up with superhard, refractory unobtainium, based on boron nitride, to sheath a drill ship that can propel itself through Earths mantle, while not baking the people inside it to a crisp.. Personally I think the script writers missed a great opportunity by not naming unobtainium, which obviously was obtainable, brazzletonite instead.. Everybody knows that boron nitride crystals are six times harder than diamond, Brazzleton says. Well… boron nitride is certainly an interesting ...

Fluorescence imaging is a powerful tool in biomedical research. It has been frequently used to uncover or better understand physiological mechanisms in disease-related processes such as cancer. The majority of chromophores used for imaging are based on a 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) scaffold. However, their applications are limited due to their poor water solubility as well as poor cancer cell selectivity. To circumvent these drawbacks, we present herein the use of bis(dipyrrinato)zinc(II) complexes. As this class of compounds is associated with a quenching effect of the excited state in water, the lead compound of this study (3) was encapsulated in a polymer matrix with biotin as a targeting moiety (3-NP). This encapsulation improved the water solubility, overcame the quenching effects in water, as well as allowed selective accumulation in the lysosomes with a bright fluorescence signal in monolayer cells as well as 3D multicellular tumor spheroids (MCTS). As a benefit ...

A method for producing products for treating wood and other cellulose products to improve the flame retardancy, and the insecticidal and fungicidal properties of the products. A calcium borate ore, such as colemanite, is reacted first with an acid such as acetic acid. The reaction products, including calcium in solution, are then treated with ammonia, producing ammonium pentaborate. The resulting composition is applied to the wood or other cellulose products by methods such as pressure, diffusion, or immersion and/or dipping treatment. The products have superior leach resistance to water when compared to conventional treatment compounds.

Boron | Gardens Alive!Boron | Gardens Alive!
Boron is the most widely deficient minor nutrient in vegetable crop soils. It is needed for protein synthesis and increases flower set, crop yield and quality. In combination with adequate phosphorus, boron increases pollination, fruit set and seed development. Boron deficiency causes growth reduction at the growing tips. Plants have small, crinkled, deformed leaves with large areas of discoloration. Boron deficiency is often caused by application of too much lime. While boron is essential for root growth and fruit development, it can become toxic if over-applied. Always test the soil and apply only the recommended amount. The deformed fruit of these strawberries is due to a deficiency of boron, which also deforms the plants leaves and roots. Bushy, drooping, crinkled leaves indicate boron deficiency in potato plants.

AU - Shcheynikov, Nikolay. AU - Zeng, Weizong. AU - Muallem, Shmuel. PY - 2004/11/5. Y1 - 2004/11/5. N2 - Boron is a vital micronutrient in plants and may be essential for animal growth and development. Whereas the role of boron in the life cycle of plants is well documented, nothing is known about boron homeostasis and function in animal cells. NaBC1, the mammalian homolog of AtBor1, is a borate transporter. In the absence of borate, NaBC1 conducts Na+ and OH- (H+), while in the presence of borate, NaBC1 functions as an electrogenic, voltage-regulated, Na+-coupled B(OH)4 - transporter. At low concentrations, borate activated the MAPK pathway to stimulate cell growth and proliferation, and at high concentrations, it was toxic. Accordingly, overexpression of NaBC1 shifted both effects of borate to the left, ...

Epitaxial CVD growthof sp2-hybridized boron nitrideusing aluminum nitride as buffer layerEpitaxial CVD growthof sp2-hybridized boron nitrideusing aluminum nitride as buffer layer
The aim of this work was to develop a chemical vapour deposition process and understand the growth of sp2 hybridised Boron Nitride (sp2-BN). Thus, the growth on different substrates together with the variation of growth parameters was investigated in details and is presented in the papers included in this thesis. Deposited films of sp2-BN were characterised with the purpose to determine optimal deposition process parameters for the growth of high crystal quality thin films with further investigations of chemical composition, morphology and other properties important for the implementation of this material towards electronic, optoelectronic devices and devices based on graphene/BN heterostructures.. For the growth of sp2-BN triethyl boron and ammonia were employed as B and N precursors, respectively. Pure H2 as carrier gas is found to be necessary for the growth of crystalline sp2-BN. Addition of small amount of silane to the gas mixture improves the crystalline quality of the growing sp2-BN ...

Meox2/Tcf15 Heterodimers Program the Heart Capillary Endothelium for Cardiac Fatty Acid UptakeCLINICAL PERSPECTIVE | CirculationMeox2/Tcf15 Heterodimers Program the Heart Capillary Endothelium for Cardiac Fatty Acid UptakeCLINICAL PERSPECTIVE | Circulation
Using a combination of gain- and loss-of-function experiments, we showed that CD36 is downstream of Meox2/Tcf15-mediated uptake of FFAs originating from both bovine serum albumin conjugates and VLDL particles in heart ECs. The high CD36 expression levels in comparison with other transporter genes in heart ECs further support its important role in cardiac FA uptake. Nevertheless, although, in our DiI-VLDL assay, CD36s contribution to Meox2/Tcf15-driven FFA uptake could have been underestimated by simultaneous detection of particle uptake, the fact that CD36 knockdown only partially impaired Meox2/Tcf15-driven uptake of BODIPY-labeled FFAs suggests the existence of other Meox2/Tcf15 downstream mediators or the occurrence of compensatory mechanisms upon CD36 knockdown.. In Meox2+/−:Tcf15+/− heart ECs, Fatp3, a FA transporter regulated by the paracrine VEGF-B,21 was increased, but this was not sufficient to fully compensate for the partial loss of CD36 induced by Meox2+Tcf15 haplodeficiency, ...
