    The heat capacity of high purity electrotransport refined lutetium was measured between 1 and 20 0 K. Results for theta/sub D/ were in excellent agreement with theta values determined from elastic constant measurements. The heat capacity of a series of lutetium-hydrogen solid solution alloys was determined and results showed an increase in γ from 8.2 to about 11.3 mJ/g-atom-K 2 for hydrogen content increasing from zero to about one atomic percent. Above one percent hydrogen γ decreased with increasing hydrogen contents. The C/T data showed an increase with temperature decreasing below about 2.5 0 K for samples with 0.1 to 1.5 atomic percent hydrogen. This accounts for a large amount of scatter in theta/sub D/ versus hydrogen content in this range. The heat capacity of a bulk sample of lutetium dihydride was measured between 1 and 20 0 K and showed a large increase in theta/sub D/ and a large decrease in γ compared to pure lutetium

    The thermal decomposition of lutetium(III) propionate monohydrate (Lu(C2H5CO2)3·H2O) in argon was studied by means of thermogravimetry, differential thermal analysis, IR-spectroscopy and X-ray diffraction. Dehydration takes place around 90 °C. It is followed by the decomposition of the anhydrous...... °C. Full conversion to Lu2O3 is achieved at about 1000 °C. Whereas the temperatures and solid reaction products of the first two decomposition steps are similar to those previously reported for the thermal decomposition of lanthanum(III) propionate monohydrate, the final decomposition...... of the oxycarbonate to the rare-earth oxide proceeds in a different way, which is here reminiscent of the thermal decomposition path of Lu(C3H5O2)·2CO(NH2)2·2H2O...

    The behaviour at different temperatures, shaking times and hydrochloric acid concentrations on the solvent extraction system UO 2 2+ - (Tm 3+ , Yb 3+ , Lu 3+ ) - H 2 O - HCl - TBP was studied. Quantitative determinations of the elements were performed by visible spectrophotometry and X-ray fluorescence. The uranyl ion was efficiently extracted by TBP from an aqueous hydrochloric acid solution (4-7M) shaken during 10 minutes at room temperature. On these conditions the separation factors for uranium from thulium and ytterbium were found to be 3000 and from lutetium 140. (author)

    The MEDICIS-PROMED Innovative Training Network under the Horizon 2020 EU program aims to establish a network of early stage researchers, involving scientific exchange and active cooperation between leading European research institutions, universities, hospitals, and industry. Primary scientific goal is the purpose of providing and testing novel radioisotopes for nuclear medical imaging and radionuclide therapy. Within a closely linked project at CERN, a dedicated electromagnetic mass separator system is presently under installation for production of innovative radiopharmaceutical isotopes at the new CERN-MEDICIS laboratory, directly adjacent to the existing CERN-ISOLDE radioactive ion beam facility. It is planned to implement a resonance ionization laser ion source (RILIS) to ensure high efficiency and unrivaled purity in the production of radioactive ions. To provide a highly efficient ionization process, identification and characterization of a specific multi-step laser ionization scheme for each individual element with isotopes of interest is required. The element lutetium is of primary relevance, and therefore was considered as first candidate. Three two-step excitation schemes for lutetium atoms are presented in this work, and spectroscopic results are compared with data of other authors.

    We report here first Perturbed Angular Correlation (PAC) results of the electric field gradient (EFG) characterisation at 111 Cd impurities located at both non-equivalent cation sites of the bixbyite structure of Lutetium sesquioxide, between room temperature (RT) and 1273 K. The comparison with results coming from a systematic 111 Cd PAC study in bixbyites and with point-charge model (PCM) predictions shows the presence of a trapped defect at RT in the neighbourhood of the asymmetric cation site, which is completely removed at T > 623 K. The anomalous EFG temperature dependence in Lu 2 O 3 can be described in the frame of a 'two-state' model with fluctuating interactions, which enables the experimental determination of the acceptor energy level introduced by the Cd impurity in the band-gap of the semiconductor and the estimation of the oxygen vacancy density in the sample

    The detailed bandstructure and superconducting behaviour of lutetium at 230 kbar pressure is reported here. The electronic contribution eta to the electron-phonon mass enhancement lambda is studied within the rigid muffin-tin (RMT) approximation. The pd and df matrix elements are expressed in terms of 'd' bandwidth, Fermi energy and muffin-tin zero. The variations of Grueneisen parameter and Debye temperature with pressure are studied and applied in the calculation of Tsub(c). The calculated Tsub(c) value agrees fairly well with the experimental value. The changes in the conduction bandwidth and the electronic specific heat coefficient with pressure are found to be in agreement with theoretical prediction. (author)

    The neutron radiative capture is a nuclear reaction that occurs in the presence of neutrons on all isotopes and on a wide energy range. The neutron capture range on Lutetium isotopes, presented here, illustrates the variety of measurements leading to the determination of cross sections. These measurements provide valuable fundamental data needed for the stockpile stewardship program, as well as for nuclear astrophysics and nuclear structure. Measurements, made in France or in United-States, involving complex detectors associated with very rare targets have significantly improved the international databases and validated models of nuclear reactions. We present results concerning the measurement of neutron radiative capture on Lu 173 , Lu 175 , Lu 176 and Lu 177m , the measurement of the probability of gamma emission in the substitution reaction Yb 174 (He 3 ,pγ)Lu 176 . The measurement of neutron cross sections on Lu 177m have permitted to highlight the process of super-elastic scattering

    In this work is described the optimization of the reaction conditions to obtain the complex 177 Lu-Dota-TATE with a radiochemical purity > 95%, even so the studies of stability In vitro to the dilution in saline solution, stability in human serum and challenge to the cystein. The biodistribution studies are presented in mice Balb-C and the tests of biological recognition using one lines cellular of pancreatic adenoma (AR42-J). The obtained results show a high stability of the radio complex in vitro, since it doesn't suffer trans chelation from the Lutetium-177 to plasmatic proteins. The biodistribution tests in mice Balb-C demonstrated an appropriate lipophilly of the complex to be excreted in more proportion by the kidneys without significant accumulation in healthy tissues. It is necessary to mention that the drop activity specifies (3.54 μg / 37 MBq) obtained in the irradiation of 176 Lu 2 O 3 it allowed to verify the union of the 177 Lu-Dota-Tate to membrane receivers but without being able to obtain the saturation curves and competition required to characterize quantitatively the biological recognition.

    Highlights: • The coefficients of thermal expansion (α{sub ‖}, α{sub ⊥}) were measured for lutetium tetraboride. • The simplified Lutetium tetraboride phonon spectrum model is developed. • The Grüneisen parameters Γ, Γ{sub ‖}, Γ{sub ⊥} for lutetium tetraboride is calculated. • The anomalies of Γ{sub ‖}(T), Γ{sub ⊥}(T) at about 25 K are due to Einstein vibrations of boron sublattices. - Abstract: The coefficients of thermal expansion to the c axis (α{sub ‖}, α{sub ⊥}) were measured for lutetium tetraboride over the temperature range 4.2–300 K. The heat capacity data for lutetium tetraboride were used for the calculation of tetraboride phonon spectrum moments and also for the development of a simplified tetraboride spectrum model. The use of the heat capacity and thermal expansion data allowed the temperature changes of the Grüneisen parameters Γ, Γ{sub ‖}, Γ{sub ⊥} for tetraboride to be calculated. As a result of the approximation of Γ{sub ⊥}(T), Γ{sub ‖}(T) temperature dependencies in accordance with the chosen phonon spectrum model have been found: the anomalies of Γ{sub ⊥}(T), Γ{sub ‖}(T) are at about 25 K and then drop at lower temperatures due to the Einstein vibrations of boron sublattices.

    Peptide Receptor Radionuclide Therapy (PRRT) with yttrium-90 ((90)Y) and lutetium-177 ((177)Lu)-labelled SST analogues are now therapy option for patients who have failed to respond to conventional medical therapy. In-house production with automated PRRT synthesis systems have clear advantages over manual methods resulting in increasing use in hospital-based radiopharmacies. We report on our one year experience with an automated radiopharmaceutical synthesis system. All syntheses were carried out using the Eckert & Ziegler Eurotope's Modular-Lab Pharm Tracer® automated synthesis system. All materials and methods used were followed as instructed by the manufacturer of the system (Eckert & Ziegler Eurotope, Berlin, Germany). Sterile, GMP-certified, no-carrier added (NCA) (177)Lu was used with GMP-certified peptide. An audit trail was also produced and saved by the system. The quality of the final product was assessed after each synthesis by ITLC-SG and HPLC methods. A total of 17 [(177)Lu]-DOTATATE syntheses were performed between August 2013 and December 2014. The amount of radioactive [(177)Lu]-DOTATATE produced by each synthesis varied between 10-40 GBq and was dependant on the number of patients being treated on a given day. Thirteen individuals received a total of 37 individual treatment administrations in this period. There were no issues and failures with the system or the synthesis cassettes. The average radiochemical purity as determined by ITLC was above 99% (99.8 ± 0.05%) and the average radiochemical purity as determined by HPLC technique was above 97% (97.3 ± 1.5%) for this period. The automated synthesis of [(177)Lu]-DOTATATE using Eckert & Ziegler Eurotope's Modular-Lab Pharm Tracer® system is a robust, convenient and high yield approach to the radiolabelling of DOTATATE peptide benefiting from the use of NCA (177)Lu and almost negligible radiation exposure of the operators.

    Full Text Available Background & Objectives: The monoclonal antibody cetuximab binds to EGFR and thus provides an opportunity to create both imaging and therapeutic modalities that target this receptor. The potential of cetuximab as a radioimmunoconjugate was investigated and quality control tests (in vitro and in vivo were performed as a first step in the production of a new radiopharmaceutical.   Methods : Cetuximab solution was dialyzed and concentrated using an Amicon Ultra-15 filter. Purified antibody was labeled with lutetium-177 using the acyclic bifunctional chelator, DOTA-NHS, and radioimmunoconjugates were purified by PD10 columns. Radiochemical purity and stability in buffer and human blood serum were determined using thin layer chromatography. Integrity of the radiolabeled complex was checked by SDS-PAGE. Preliminary biodistribution studies in normal mice model performed to determine radioimmunoconjugates distribution up to 72h.   Results: The radiochemical purity of the complex was 98±1%. The stabilities in phosphate buffer and in human blood serum at 96 hours post-preparation were 96±2 % and 78±4%, respectively. All of the samples, controls and radiolabeled antibodies, showed a similar pattern of migration in the gel electrophoresis. Biodistribution of Lu177-cetuximab was evaluated in normal mice and the highest ID/g% was observed in the blood (13.2±1.3% at 24 hours and the liver (9.1±1.3% at 24 hours.   Conclusion: Our results show that DOTA-cituximab can be labeled with 177Lu. Lu177-cetuximab has sufficient stability and retains its integrity. The new complex could be considered for further evaluation in animals and possibly in humans as a new radiopharmaceutical for use in radioimmunotherapy of cancers.

    Lutetium and yttrium borates doped with europium, terbium, gadolinium, etc. have been synthesized by dissolving initial oxides and nitrates in ammonium nitrate melt and thermal decomposition of the solvent. Annealings in the range of 500-1100 deg. C modified the dimensions of the grains from 2 to 3 nm to more than 100 nm. Significant dependence of the structure of lutetium borate on slight doping with rare earth ions has been found: terbium makes high-temperature vaterite phase preferential at room temperature, whereas europium stabilizes low-temperature calcite phase. Influence of the structure of the borates on the pattern of the luminescence spectra of europium dopant was observed. Possibilities for manufacturing of scintillating lutetium borate ceramics by means of this method of synthesis are discussed

    Highlights: ► Sequence of volumes and compressibilities of Ln 3+ ions in DMSO is: La 3+ > Gd 3+ 3+ . ► Sequence of the partial molar volumes do not change with temperature. ► These results are the consequence of nature of the ion–solvent bonding. - Abstract: Temperature dependencies of the densities of dimethylsulfoxide solutions of lanthanum, gadolinium and lutetium trifluoromethanesulfonates have been determined over a wide range of concentrations. The apparent molar volumes and partial molar volumes of the salts at infinite dilution, as well as the expansibilities of the salts, have been calculated from density data. Additionally, the apparent molar isentropic compressibilities of lanthanum, gadolinium and lutetium trifluoromethanesulfonates have been calculated from sound velocity data at 298.15 K. The data obtained have been interpreted in terms of ion−solvent interactions.

Sequence of EDDA (A 2- ) protonation was established; cations H 3 A + and H 4 A 2+ were found; dissociation constants of above mentioned cations were determined. Formation of H 2 LnA 3+ , HLnA 2+ and LnA + complexes in EDDA-Ln (1:1) system was found. Difference in the bonds mobility of lanthanum and lutetium complexes was determined: lanthanum forms complexes with labile, lutetium with non-labile bonds. Information on complexes structure is collected. Acid dissociation constants of protonated complexes of lanthanum with EDDA were determined

    The solubility product constants and the first of lutetium hydrolysis in the interval of initial concentration of 3.72 X 10 -5 to 2.09 X 10 -3 M of lutetium, in a 2M of NaCIO 4 media, at 303 K and under conditions free of CO 2 its were considered. The solubility diagrams (pLu (ac) -pC H ) by means of a radiochemical method were obtained, and starting from its the pC H values that limit the saturation and no-saturation zones of the solutions were settled down. Those diagrams allowed, also, to calculate the solubility product constants of Lu(OH) 3 . The experimental data to the polynomial solubility equation were adjusted, what allowed to calculate those values of the solubility product constants of Lu(OH) 3 and to determine the first hydrolysis constant. The value of precipitation pC H diminishes when the initial concentration of the lutetium increases, while the values of K ps and β 1,H its remain constant. (Author)

    The structure and dynamics of the lutetium(III) ion in aqueous solution have been investigated by means of a polarizable force field molecular dynamics (MD). An 8-fold square antiprism (SAP) geometry has been found to be the dominant configuration of the lutetium(III) aqua ion. Nevertheless, a low percentage of 9-fold complexes arranged in a tricapped trigonal prism (TTP) geometry has been also detected. Dynamic properties have been explored by carrying out six independent MD simulations for each of four different temperatures: 277 K, 298 K, 423 K, 632 K. The mean residence time of water molecules in the first hydration shell at room temperature has been found to increase as compared to the central elements of the lanthanoid series in agreement with previous experimental findings. Water exchange kinetic rate constants at each temperature and activation parameters of the process have been determined from the MD simulations. The obtained structural and dynamical results suggest that the water exchange process for the lutetium(III) aqua ion proceeds with an associative mechanism, in which the SAP hydration complex undergoes temporary structural changes passing through a 9-fold TTP intermediate. Such results are consistent with the water exchange mechanism proposed for heavy lanthanoid atoms.

    We report a novel approach for synthesizing LuPO4/apoferritin core-shell nanoparticles based on an apoferritin template, conjugated to the protein biotin. To prepare the nanoparticle conjugates, we used non-radioactive lutetium as a model target or surrogate for radiolutetium (177Lu). The central cavity, multi-channel structure, and chemical properties of apoferritin are well-suited for sequentially diffusing lutetium and phosphate ions into the cavity--resulting in a stable core-shell composite. We characterized the synthesized LuPO4/apoferritin nanoparticle using transmission electron microscopy (TEM) and x-ray photoelectron spectroscopy (XPS). We tested the pre-targeting capability of biotin-modified lutetium/apoferritin nanoparticle using streptavidin-modified magnetic beads and streptavidin-modified fluorescein isothiocyanate (FITC) tracer. This paper presents a simple, fast, and efficient method for synthesizing LuPO4/apoferritin nanoparticle conjugates with biotin for potential applications in radioimmunotherapy and radioimmunoimaging of cancer

    An X-ray fluorescence spectrometric method for the analysis of lutetium oxide is described. The sample in the oxalate form is mixed with boric acid binding material and pressed into a pellet over supporting pellet of boric acid. A Philips PW 1220 wavelength dispersive semiautomatic X-ray fluorescence spectrometer is used for the analysis. The minimum determination limit is 0.002 percent for Y, Er and Yb and 0.005 percent for Tm. Calculations for theoretical minimum detection limits and percent standard deviations at each concentration of the standard are carried out. (author)

    For rapid, unambiguous isotope identification, scintillator detectors providing high-resolution gamma ray spectra are required. We have fabricated Lutetium Aluminum Garnet (LuAG) using transparent ceramic processing, and report a 2-mm thick ceramic exhibiting 75% transmission and light yield comparable to single-crystal LuAG:Ce. The LuAG:Ce luminescence peaks at 550 nm, providing an excellent match for Silicon Photodiode readout. LuAG is dense (6.67 g/cm 3 ) and impervious to water, exhibits good proportionality and a fast decay (∼40 ns), and we measure light yields in excess of 20,000 photons/MeV

    1987-01-01

    A 3000-liter feed adjustment tank containing over 2400 L of uranium solution was assayed for its contents using the double spiking technique of isotope dilution mass spectrometry. Lutetium was the double spike, with the natural element used as the initial spike and enriched 176-Lu as the second. The ability of a remote sampling system was evaluated for its ability to introduce the lutetium and also to produce homogeneous sample solutions. The system was found to be satisfactory. Volumes of the tank can be measured to a precision of about 0.2%. The concentration of uranium was measured as 154.5 g/L uranium, thus giving a total of 382.3 kg in the tank as compared to the plant's best estimate of 383 kg. Uranium measurements were subjected to internal calibration calculations, with 233-U and 236-U being used as the reference isotopes. A diversion of 5% of the tank contents was simulated to evaluate the method's sensitivity in this regard. The ability of this method to give timely results of good precision makes it a strong candidate for use in material balance and inventory accountability applications; it also has potential use in quality assurance areas

  11. Optical emission spectrographic analysis of lutetium oxide for rare earth impurities

    International Nuclear Information System (INIS)

    Chandola, L.C.; Dixit, V.S.

    1986-01-01

    An optical emission spectrographic (OES) method has been developed for the analysis of high purity lutetium oxide to determine rare earths Er, Tm, Yb and Y. The spectra are excited by a d.c. arc run at 10 A current after mixing the sample with graphite buffer in the weight ratio 1:1. A 1200 grooves/mm grating blazed at 3300 A is used for dispersion and a Kodak SA-1 plate for recording the spectrum. The detection limit is 0.001 per cent for Tm, Yb and Y while it is 0.005 per cent for Er. The relative standard deviation of the method is ± 13.4 per cent. (author)

    Both photoelectric and electrochromic effects on lutetium tetrakis(tert-butyl)bisphthalocyaninate (Lu(TBPc) 2 ) have been carried out in this study. Lu(TBPc) 2 is known for its electrochromic performance, but its photoelectric effect has not mentioned in the literature. The electrochromic properties of Lu(TBPc) 2 have been measured by cyclic voltammetry (CV) and UV-Vis spectrometer at the same time. It takes less than 1.5 s for the color to change from red to green under 0.9 V. Its cycle life is at least over 500 times. Furthermore, we also investigate its photoelectric conversion properties. Its photoelectric cell exhibits a positive photo-electricity conversion effect with a short-circuit photocurrent (46.4 μA/cm 2 ) under illumination of white light (1.201 mW/cm 2 )

    Results of spectral-electrochemical study on electrochromic films of blue form of tret-butyl-substituted lutetium diphthalocyanine deposited on the surface of an electrode contacting with electrolyte aqueous solution are presented. In the 0.2-1.15 V potential range sweep of the electrode potential is followed by reversible change of the film colour in the following succession: blue reversible green reversible red. Electrochromic properties of the film confirm the corresponding spectral transitions from the initial state to monoelectron-oxidized and further on to the product of two-electron oxidation. Under potential sweeping towards the anode in the 1.4 V range and irreversible wave arises; potential achievement of this wave brings about complete change in the form of j, E-curves. The consequent electrode processes are followed by change in the film colour green - red that is associated witn mechanical fracture of the film.

    Easy large-scale production, easy availability, cost-effectiveness, long half-life, and favorable radiation characteristics have made lutetium-177 (Lu) a preferred radionuclide for use in therapy. Lutetium-177-labeled stannous (Lu-Sn) colloid particles were formulated for application in radiosynovectomy, followed by in-vitro and in-vivo characterization. Stannous chloride (SnCl2) solution and Lu were heated together, the pH was adjusted, and the particles were recovered by centrifugation. The heating time and amount of SnCl2 were varied to optimize the labeling protocol. The labeling efficiency (LE) and radiochemical purity (RCP) of the product were determined. The size and shape of the particles were determined by means of electron microscopy. In-vitro stability was tested in PBS and synovial fluid, and in-vivo stability was tested in humans. LE and RCP were greater than 95% and ∼99% (Rf=0-0.1), respectively. Aggregated colloidal particles were spherical (mean size: 241±47 nm). The product was stable in vitro for up to 7 days in PBS as well as in synovial fluid. Injection of the product into the infected knee joint of a patient resulted in its homogenous distribution in the intra-articular space, as seen on the scan. No leakage of activity was seen outside the knee joint even 7 days after injection, indicating good tracer binding and in-vivo stability. Lu-Sn colloid was successfully prepared with a high LE (>95%) and high RCP (99%) under optimized reaction conditions. Because of the numerous benefits of Lu and the ease of preparation of tin colloid particles, Lu-Sn colloid particles are significantly superior to its currently available counterparts for use in radiosynovectomy.

    The β-decay of 59 151 Pr 92 to the levels in 60 151 Nd 91 has been studied from the fission products of 235 U using an on-line isotope separator (KUR-ISOL). Gamma-rays and conversion electrons have been measured. Conversion coefficients have been determined for the first time. The precise decay scheme is proposed up to 2430 keV. The newly observed 65 γ-rays and 16 levels are incorporated in it. The deduced level scheme of 151 Nd was compared to the calculated level scheme on the basis of the rotation-vibration coupling model with a Nilsson potential. Low-lying levels were well reproduced by this model. (author)

    In this study, electrochemical, electrochromic and spectroelectrochemical properties of a tert-butylcalix[4]arene bridged bis double-decker lutetium(III) phthalocyanine (Lu 2 Pc 4 2) were investigated explicitly as compared with a tert-butylcalix[4]arene bridged dimeric lutetium(III) phthalocyanine [Lu 2 Pc 2 (OAc) 2 1]. Distinctive differences between electrochemical and electrochromic properties of 1 and 2 were detected. Moreover, the properties of 1 and 2 were compared with previously reported S 4 (CH 2 ) 4 bridged Lu 2 Pc 2 (OAc) 2 and Lu 2 Pc 4 . The calixarene bridged phthalocyanine (Pc) compounds, 1 and 2 showed well-defined electrochromic behaviour with green-blue and blue-purple colour transitions. The enhanced electrochromic properties of 2, as compared to 1, were attributed to its double-decker structure, probably allowing the formation of suitable ion channels for the counter ion movement in the solid film

    Local recurrence of rectal cancer remains a significant clinical problem despite multi-modality therapy. Photodynamic Therapy (PDT) is a cancer treatment which generates tumor kill through the production of singlet oxygen in cells containing a photosensitizing drug when exposed to laser light of a specific wavelength. PDT is a promising modality for prevention of local recurrence of rectal cancer for several reasons: tumor cells may selectively retain photosensitizer at higher levels than normal tissues, the pelvis after mesorectal excision is a fixed space amenable to intra-operative illumination, and PDT can generate toxicity in tissues up to 1 cm thick. This study evaluated the safety, tissue penetration of 730 nm light, normal tissue toxicity and surgical outcome in a dog model of rectal resection after motexafin lutetium-mediated photodynamic therapy. Ten mixed breed dogs were used. Eight dogs underwent proctectomy and low rectal end to end stapled anastomosis. Six dogs received the photosensitizing agent motexafin lutetium (MLu, Pharmacyclics, Inc., Sunnyvale, CA) of 2 mg/kg preoperatively and underwent subsequent pelvic illumination of the transected distal rectum of 730 nm light with light doses ranging from 0.5 J/cm(2) to 10 J/cm(2) three hours after drug delivery. Two dogs received light, but no drug, and underwent proctectomy and low-rectal stapled anastomosis. Two dogs underwent midline laparotomy and pelvic illumination. Light penetration in tissues was determined for small bowel, rectum, pelvic sidewall, and skin. Clinical outcomes were recorded. Animals were sacrificed at 14 days and histological evaluation was performed. All dogs recovered uneventfully. No dog suffered an anastomotic leak. Severe tissue toxicity was not seen. Histological findings at necropsy revealed mild enteritis in all dogs. The excitation light penetration depths were 0.46 +/- 0.18, 0.46 +/- 0.15, and 0.69 +/- 0.39 cm, respectively, for rectum, small bowel, and peritoneum in

    The enthalpies of mixing in binary liquid alloys of lutetium with chromium, cobalt, nickel and copper were determined at 1 773 - 1 947 K by isoperibolic calorimetry. The enthalpies of mixing in the Lu-Cr melts (measured up to 40 at.% Cr) demonstrate endothermic effects (ΔH = 6.88 ± 0.66 kJ . mol{sup -1} at x{sub Lu} = 0.60), whereas significant exothermic enthalpies of mixing have been established within a wide composition region for the Co-Lu, Ni-Lu and Cu-Lu liquid alloys. Minimum values of the integral enthalpy of mixing are as follows: ΔH{sub min} = -23.57 ± 1.41 kJ . mol{sup -1} at x{sub Lu} = 0.38 for the Co-Lu system; ΔH{sub min} = -48.65 ± 2.83 kJ . mol{sup -1} at x{sub Lu} = 0.40 for the Ni-Lu system; ΔH{sub min} = -24.63 ± 1.52 kJ . mol{sup -1} at x{sub Lu} = 0.37 for the Cu-Lu system.

  20. Optical Fibre NO2 Sensor Based on Lutetium Bisphthalocyanine in a Mesoporous Silica Matrix

    Directory of Open Access Journals (Sweden)

    Marc Debliquy

    2018-03-01

    Full Text Available In this article, we describe a NO2 sensor consisting of a coating based on lutetium bisphthalocyanine (LuPc2 in mesoporous silica. The sensor exploits the absorption spectrum change of this material which strongly and reversibly decreases in contact with NO2. NO2 is measured by following the amplitude change in the reflected spectrum of the coating deposited on the tip of a silica fibre. As diffusion of NO2 in LuPc2 is slow, the response time could be slow. To reduce it, the active molecules are dispersed in a mesoporous silica matrix deposited by a sol-gel process (Evaporation Induced Self Assembly avoiding the formation of large crystals. Doing so, the response is fairly fast. As the recovery is slow at room temperature, the recovery time is reduced by exposure to UV light at 365 nm. This UV light is directly introduced in the fibre yielding a practical sensor sensitive to NO2 in the ppm range suitable for pollution monitoring.

    Full Text Available This paper argues the recent proposals expressed by the Australian Accounting StandardBoard in Exposure Draft 151 contradicts the historical trend of standard setters attemptingto achieve the objective of financial reporting, that is, the provision of decision-usefulinformation for users of general purpose financial reports. Historically, standard settershave tried to achieve this objective by reducing alternative treatments in accountingstandards and providing increasing levels of information for users. Exposure Draft 151affects many standards, however, this paper focuses on the proposal to allow preparers theoption of selecting between the direct or indirect method of presenting cash flows fromoperations in the statement of cash flows. We argue that this discretion contradicts thestated objective of financial reporting, as stated in the Conceptual Framework, as it will leadto the widespread adoption of the less informative indirect method, due to a structural biasin the requirements of AASB 107 and IASB 7, the relevant standards relating to thestatement of cash flows.

  19. Lutetium-177 - Broad Production Capabilities are Expected to Stimulate Clinical Applications of this Important Therapeutic Radioisotope

    International Nuclear Information System (INIS)

    Knapp, F.F. Jr.

    2009-01-01

    Lutetium-177 (Lu-177) is of broad interest for therapeutic applications where the deposition of localized radiation can benefit from the limited soft tissue penetration of the 0.497 MeV beta particle (max. = 2.76 mm). Examples of Lu-177 therapeutic strategies include treatment of small SS2/SS5-expressing tumors with targeted peptides and radiosynovectomy. Emission of a 208 keV gamma photon (11 %) allows imaging for evaluation of localization and biokinetics, and for targeting applications, correlation of uptake with therapeutic response. A broad spectrum of research reactors with even modest thermal neutron flux (e.g. > 1 x 10 14 ) can produce carrier-added Lu-177 with sufficient specific activity (SA) > 10 Ci/mg Lu by the 'direct' approach by irradiation of Lu-176. For low SA applications, thermal flux of > 10 13 in low-medium flux reactors provides sufficient SA (> 0.5 mCi Lu-177/mg) for preparation of Lu-EDTMP for synovectomy. Although relative Lu-177m/Lu-177 activity levels from 'direct' production can be very low (> 10 -5 ), the Lu-177m impurity levels can present an issue with radioactive waste storage requirements at some institutions. The alternative 'indirect' approach using decay of reactor produced ytterbium-177 available from by neutron irradiation of enriched Yb-176 targets provides no-carrier-added (nca) Lu-177 (theoretical SA = 109 Ci/mg Lu). Purification of the microscopic levels of nca Lu-177 from macroscopic Yb levels at the high multi Curie production level is a more challenging approach, since production yields are relatively low even at high thermal flux (e.g. 2 x 10 15 neutrons/cm 2 /sec). In addition, high mass Lu/Yb separation is especially time consuming, can generate significant waste, and the relatively expensive Yb-176 target material (> 97%, ∼ $ 20/mg) must be recovered, re-purified and used for subsequent target preparation. However, a number of effective methods for the Lu/Yb separation and Yb recovery have been reported, and even

    We earlier reported the results of our investigations of electron spectra of radioactive lutetium oxide films on the magnetic β-spectrometer π√2 with momentum resolution 0.04-0.1 %. The researches were conducted many times during ≅15 years, and a lot of the data has resulted us in the conclusion about possible formation of toroidal structures in these films. It is impossible to consider a radioactive oxide layer, deposited on metallic foil support having the electric potential of its foil support on all its depth because of its high dielectric properties. There is the potential gradient (≅10 6 -10 7 V/c) on its depth because of constant outflow of electrons from its surface. Our experiments included in itself also giving a potential, accelerating for electrons, to the metallic foil support. In this case we received a capability to watch the segments of auto emission and low energy Auger electrons. The analysis of the threshold relations and behavior (in time) of the M 4 NN and M 5 NN Auger electron intensities have resulted us in the conclusion that the greatest contribution to structure formations of these oxide films is introduced by electrons of M 4 -, M 5 - and N-sub-shell of ytterbium atoms (being formed as the result of radioactive decay of the lutetium fraction with half-times from 140 to 1200 days). The auto emission electron spectrum testifies to composite scission of M4 and M5 stationary states of the atom. It is possible to offer as the explanation a quantum flat rotator. If the particle orbit un-compresses the solenoid with a magnetic flux Φ, power condition of a rotator E m =h 2 (m-Φ/Φ 0 ) 2 /(8πm e R 0 2 ), where m e - electron mass, R 0 - an electron orbit radius; m - a magnetic quantum number, a Φ 0 =h c/e - a quantum of magnetic flux. At a quantum flow Φ=nΦ 0 (n - integer) and the power spectrum does not differ from a spectrum without the solenoid. The behavior (in time) of the experimental auto emission electron spectrum responds

    The stability constants of La 3+ , Pr 3+ , Eu 3+ , Er 3+ and Lu 3+ chloride complexes were determined in perchloric acid media using a liquid-liquid extraction method. The dinonyl napthalene sulfonic acid in n-heptane was used as extractant. The lanthanide (Ln) concentrations were measured by a radiochemical (Eu and Lu) and a spectrophotometric (La, Pr, and Er) methods. In the last method, xylenol orange was used for the determinations at ph 6. The stability constants of lanthanum, praseodymium, erbium and lutetium chloride complexes were determined in 2, 3 and 4 M ionic strength and europium in 1, 2 and 3 M, at 303 K. The fitting of experimental data to the equations for the calculation of the stability constants, was carry out considering both one chemical species (LnCl 2+ ) or two chemical species (LnCl 2+ and LnCl 2 + ). The Specific Ion Interaction Theory was applied to the values of log β I Ln , Cl and the first stability constants at zero ionic strength were calculated by extrapolation. The same theory could not be applied to the log β I Ln , 2Cl , due to its low abundance and the values determined for the stability constants were similar. The distribution diagrams of the chemical species were obtained using the program MEDUSA and considering log β I Ln , CI , log β I Ln , 2CI values obtained in this work and the hydrolysis constants taken from the literature. The lanthanide chloride complexes are present in solution at specific conditions of ionic strength, concentration and in the absence of hydrolysis. The log β I Ln , Cl data were related to the charge density and the corresponding equations were obtained. These equations could be used to determine the stability constants along the lanthanide series. (Author)

    In this article, we present new experimental data regarding the influence of ammonia (NH 3 ) and water (from wet atmospheres) in the conducting properties of lutetium bisphthalocyanine (LuPc 2 )-based films in two very different structural features, namely Langmuir-Blodgett (LB) and vacuum evaporated (VE) films, deposited onto interdigitated electrodes. We pay particular attention to the effect of the mass flow rate ratios of the active gases, which certainly influence the mechanism of conduction of the chemiresistors. The particular trends observed are discussed on the basis of two main contributions: the electronic effects and the competition between gases in the adsorption process

    -limited and manageable. In a physician-sponsored Australian Phase II clinical study grade III/IV haematological toxicity occurred (4% platelets, 16% neutrophils). Objective response rate (ORR) was 76% and Complete Remission (CR) was achieved in 53% (3). The majority of our patients now qualify for outpatient radioimmuno-therapy with 131 Irituximab and monitoring of carer radiation exposure demonstrates that the IAEA and ICRP guidelines of less than 5 mSv per episode of treatment were satisfied in all carers, and visitors to the household were exposed to less than 1 mSv. First-line 131 I-rituximab is now given to patients presenting with newly diagnosed indolent stage IIB, III, IV follicular non-Hodgkin's lymphoma who do not wish to be exposed to the toxic effects of induction chemotherapy. In the INITIAL phase II clinical trial at Fremantle Hospital, after first-line 131 I-rituximab radioimmunotherapy, patients also undergo maintenance rituximab therapy to maintain remission. Clinical ORR is 100% with 80% CR in all patients, as evaluated by 18F-FDG PET imaging at 3 months. This is comparable with the reported ORR of first-line radioimmuno-therapy with 131 I-tositumomab (Bexxar) (4) and achieves the same ORR of standard R-CHOP chemotherapy regimens without the associated toxicity, or any requirement for hospital admission. 2. Lutetium-177 Octreotate Neuroendocrine malignancy is not amenable to chemotherapy and if unresectable due to metastases, usually in liver, the only effective treatment with intent-to cure is radiopeptide therapy. Lutetium-177 octreotate has been demonstrated to achieve ORR 45%, CR 2% (5) which is better than the results of the most effective but relatively more toxic chemotherapy regimen of Streptozotocin + 5FU + Doxorubicin. In an attempt to improve response rates we performed a pilot study of 177 Lu octreotate and capecitabine chemotherapy radiosensitizing therapy comprising 4 cycles of 7.4 GBq 177 Lu-octreotate with 2 weeks 1600 mg/m 2 capecitabine, at

    Although the physiological impact of the actinide elements as nuclear toxicants has been widely investigated for half a century, a description of their interactions with biological molecules remains limited. It is however of primary importance to better assess the determinants of actinide speciation in cells and more generally in living organisms to unravel the molecular processes underlying actinide transport and deposition in tissues. The biological pathways of this family of elements in case of accidental contamination or chronic natural exposure (in the case of uranium rich soils for instance) are therefore a crucial issue of public health and of societal impact. Because of the high chemical affinity of those actinide elements for phosphate groups and the ubiquity of such chemical functions in biochemistry, phosphate derivatives are considered as probable targets of these cations. Among them, nucleotides and in particular adenosine mono- (AMP) and triphosphate (ATP) nucleotides occur in more chemical reactions than any other compounds on the earth's surface, except water, and are therefore critical target molecules. In the present study, we are interested in trans-plutonium actinide elements, in particular americium and curium that are more rarely considered in environmental and bioaccumulation studies than early actinides like uranium, neptunium and plutonium. A first step in this strategy is to work with chemical analogues like lanthanides that are not radioactive and therefore allow extended physical chemical characterization to be conducted that are difficult to perform with radioactive materials. We describe herein the interaction of lutetium(III) with adenosine AMP and ATP. With AMP and ATP, insoluble amorphous compounds have been obtained with molar ratios of 1:2 and 1:1, respectively. With an excess of ATP, with 1:2 molar ratio, a soluble complex has been obtained. A combination of spectroscopic techniques (IR, NMR, ESI-MS, EXAFS) together with quantum

    Malignant gliomas are primary brain tumors, resistant to various treatments, as chemotherapy, radiotherapy, induction of apoptosis and surgery. An alternative for the treatment of malignant gliomas is the radionuclide therapy. This technique apply radiolabeled molecules that selectively bind to tumor cells producing cytotoxic effect by dose irradiation, and resulting in death of tumor cells. Most protocols for radionuclide therapy of malignant brain tumors involve the administration of peptides labeled with β - emitting radioisotopes. The Substance P (SP) is an 11- amino acid neuropeptide, characterized by the C-terminal sequence Phe-X-Gly-Leu-Met-NH 2 . The use of SP labeled with different radionuclides including 177 Lu, have been proposed for in vivo treatment of tumors. SP is the most important target of neurokinin 1 receptors, over expressed in malignant gliomas. The objective of this work was to study conditions of radiolabeling DOTA-SP with 177 Lu, the stability of labeled compound and in vivo and in vitro, to develop a protocol production and evaluate the potential of the radiopharmaceutical in the therapy of gliomas. The labeling conditions were optimized varying the temperature, reaction time, activity of lutetium-177 chloride and mass of DOTA-SP. The radiochemical purity of preparations were analyzed by chromatographic techniques. The stability of 17L u -DOTA- SP radiolabeled with low activity of 177 Lu was evaluated for different time at 2-8 degree C or incubated in human serum. The stability of the labeled with high activity of 177 Lu was also analyzed in the presence of gentisic acid (6 mg / mL) added after the labeling reaction. The labeled conditions in low and high activity were subjected to evaluation for the ability to cause oxidation of methionine residue, adding the D-L- methionine amino acid to the reaction medium (6 mg / mL) and subsequent chromatographic evaluation.

    Full Text Available Human papillomaviruses (HPV are non-enveloped DNA tumor viruses that infect skin and mucosa. The most oncogenic subtype, HPV16, causes various types of cancer, including cervical, anal, and head and neck cancers. During the multistep process of infection, numerous host proteins are required for the delivery of virus genetic information into the nucleus of target cells. Over the last two decades, many host-cell proteins such as heparan sulfate proteoglycans, integrins, growth factor receptors, actin and the tetraspanin CD151 have been described to be involved in the process of infectious entry of HPV16. Tetraspanins have the ability to organize membrane microdomains and to directly influence the function of associated molecules, including binding of receptors to their ligands, receptor oligomerization and signal transduction. Here, we summarize the current knowledge on CD151, and CD151-associated partners during HPV infection and discuss the underlying mechanisms.

    In this work is described the optimization of the reaction conditions to obtain the complex {sup 177} Lu-Dota-TATE with a radiochemical purity > 95%, even so the studies of stability In vitro to the dilution in saline solution, stability in human serum and challenge to the cystein. The biodistribution studies are presented in mice Balb-C and the tests of biological recognition using one lines cellular of pancreatic adenoma (AR42-J). The obtained results show a high stability of the radio complex in vitro, since it doesn't suffer trans chelation from the Lutetium-177 to plasmatic proteins. The biodistribution tests in mice Balb-C demonstrated an appropriate lipophilly of the complex to be excreted in more proportion by the kidneys without significant accumulation in healthy tissues. It is necessary to mention that the drop activity specifies (3.54 {mu}g / 37 MBq) obtained in the irradiation of {sup 176} Lu{sub 2}O{sub 3} it allowed to verify the union of the {sup 177}Lu-Dota-Tate to membrane receivers but without being able to obtain the saturation curves and competition required to characterize quantitatively the biological recognition.

    Single crystals of thortveitite structure pyro-silicates were grown by a floating zone technique associated with an arc image furnace. The samples were systematically characterized by X-Ray diffraction and microprobe analysis. Thanks to oriented single crystals of Lu 2 Si 2 O 7 , Yb 2 Si 2 O 7 and Sc 2 Si 2 O 7 , the recorded infrared and Raman spectra allow complete attribution of internal and external vibration modes, in good agreement with group theory predictions for C 2h factor group. Spectroscopic studies of Eu 3+ doping ion in Lu 2 Si 2 O 7 confirm C 2 point symmetry for the cationic site. Oscillator strengths and Judd-Ofelt parameters for Eu 3+ were calculated. A three level scheme ( 1 S 0 , 3 P 0 , 3 P 1 ) of Bi 3+ ion is used to explain radiative and non radiative mechanisms in Lu 2 Si 2 O 7 doped with bismuth. Finally, the mechanisms of low temperature (T =9 K) energy transfer between Bi 3+ and Eu 3+ in lutetium pyro-silicate was studied. The transfer occurs by non radiative process, without any diffusion of the excitation energy within the donor system and is due to dipole-dipole interactions between Bi 3+ and Eu 3+ ions.

    Pancreatic tumor (PT) is a neuroendocrine neoplasm that usually origin metastases in the respiratory and gastrointestinal tract. In recent years, new developments in targeted therapies have emerged and the presence of peptide receptors at the cell membrane of PT constitutes the basis of the clinical use of specific radiolabeled ligands. Substance P, an 11-amino acid peptide which has an important role in modulating pain transmission trough neurokinin 1 and 2 receptors (NKr), may play a role in the pathogenesis of PT, because approximately 10% of these tumors over express NKr. The aim of the present work was to produce a pure and stable SP analog (DOTA-SP) radiolabeled with Lutetium-177 ( 177 Lu), and to evaluate its in vivo target to AR42J pancreatic tumor cells in Nude mice in other to verify if SP can be used in this pancreatic tumor detection and treatment. 177 Lu (half-life 6.7 days) has both β and γ-emissions suitable for radiotherapy and imaging respectively. Substance P was successfully labeled with high yield (>99%) at optimized conditions and kept stable for more than 72 hours at 4 deg C and 24 hours in human plasma. Biodistribution studies showed that SP excretion was mainly performed by renal pathway. In addition, 177 Lu-DOTA-SP showed higher uptake by tumor than normal pancreas, indicating the presence of NK receptors in AR42J pancreatic tumor. (author)

    Radionuclide therapies, including treatment of neuroendocrine tumors with lutetium-177 (Lu-177) octreotate, often involve hospital admission to minimize radiation exposure to the public. Overnight admission due to Lu-177 octreotate therapy incurs additional cost for the hospital and is an inconvenience for the patient. This study endeavors to characterize the potential radiation risk to caregivers and the public should Lu-177 octreotate therapies be performed on an outpatient basis. Dose rate measurements of radiation emanating from 10 patients were taken 30 min, 4, and 20 h after initiation of Lu-177 octreotate therapy. Instadose radiation dose measurement monitors were also placed around the patients' rooms to assess the potential cumulative radiation exposure during the initial 30 min-4 h after treatment (simulating the hospital-based component of the outpatient model) as well as 4-20 h after treatment (simulating the discharged outpatient portion). The mean recorded dose rate at 30 min, 4, and 20 h after therapy was 20.4, 14.0, and 6.6 μSv/h, respectively. The majority of the cumulative dose readings were below the minimum recordable threshold of 0.03 mSv, with a maximum dose recorded of 0.18 mSv. Given the low dose rate and cumulative levels of radiation measured, the results support that an outpatient Lu-177 octreotate treatment protocol would not jeopardize public safety. Nevertheless, the concept of ALARA still requires that detailed radiation safety protocols be developed for Lu-177 octreotate outpatients to minimize radiation exposure to family members, caregivers, and the general public.

    We report here on the first study of the level structure of 151 Ho. High spin levels in 151 Ho have been populated in the 141 Pr + 16 O and 144 Sm + 12 C reactions. The level structure has been established up to 6.6 MeV energy and the spins and particles determined up to 49/2 - . Most of the proposed level configurations can be explained by the coupling of hsub(11/2) protons to fsub(7/2) and/or hsub(9/2) neutrons. An isomer with 14 +- 3 ns half-life and a delayed gamma multiplicity equal to 17 +- 2 has been found. Its spin is larger than 57/2 h units

  19. Development of lutetium-labeled bombesin derivates: relationship between structure and diagnostic-therapeutic activity for prostate tumor

    International Nuclear Information System (INIS)

    Pujatti, Priscilla Brunelli

    2009-01-01

    Bombesin (BBN) receptors - in particular, the gastrin-releasing peptide (GRP) receptor peptide - have been shown to be massively over expressed in several human tumors types, including prostate cancer, and could be an alternative as target for its treatment by radionuclide therapy (RNT). A large number of BBN analogs had already been synthesized for this purpose and have shown to reduce tumor growth in mice. Nevertheless, most of the studied analogs exhibit high abdominal accumulation, especially in pancreas. This abdominal accumulation may represent a problem in clinical use of radiolabeled bombesin analogs probably due to serious side effects to patients. The goal of the present work was to radiolabel a novel series of bombesin derivatives with lutetium-177 and to evaluate the relationship between their structure and diagnostic-therapeutic activity for prostate tumor. The generic structure of studied peptides is DOTA-Phe-(Gly) n -BBN(6-14), where DOTA is the chelator, n is the number of glycine amino acids of Phe-(Gly) n spacer and BBN(6-14) is the bombesin sequence from the amino acid 6 to the amino acid 14. Preliminary studies were done to establish the ideal labeling conditions for obtaining the highest yield of labeled bombesin derivatives, determined by instant thin layer chromatography (ITLC-SG) and high performance liquid chromatography (HPLC). The stability of the preparations was evaluated either after storing at 2-8 degree C or incubation in human serum at 37 degree C and the partition coefficient was determined in n:octanol:water. In vivo studies were performed in both healthy Balb-c and Nude mice bearing PC-3 xenografts, in order to characterize the biological properties of labeled peptides. In vitro studies involved the evaluation of cold bombesin derivatives effect in PC-3 cells proliferation. Bombesin derivatives were successfully labeled with high yield at optimized conditions and exhibited high stability at 4 degree C. The analysis of the

    2017-04-10

    HIV-1 reverse transcriptase (RT) is targeted by multiple drugs. RT mutations that confer resistance to nucleoside RT inhibitors (NRTIs) emerge during clinical use. Q151M and four associated mutations, A62V, V75I, F77L, and F116Y, were detected in patients failing therapies with dideoxynucleosides (didanosine [ddI], zalcitabine [ddC]) and/or zidovudine (AZT). The cluster of the five mutations is referred to as the Q151M complex (Q151Mc), and an RT or virus containing Q151Mc exhibits resistance to multiple NRTIs. To understand the structural basis for Q151M and Q151Mc resistance, we systematically determined the crystal structures of the wild-type RT/double-stranded DNA (dsDNA)/dATP (complex I), wild-type RT/dsDNA/ddATP (complex II), Q151M RT/dsDNA/dATP (complex III), Q151Mc RT/dsDNA/dATP (complex IV), and Q151Mc RT/dsDNA/ddATP (complex V) ternary complexes. The structures revealed that the deoxyribose rings of dATP and ddATP have 3'-endo and 3'-exo conformations, respectively. The single mutation Q151M introduces conformational perturbation at the deoxynucleoside triphosphate (dNTP)-binding pocket, and the mutated pocket may exist in multiple conformations. The compensatory set of mutations in Q151Mc, particularly F116Y, restricts the side chain flexibility of M151 and helps restore the DNA polymerization efficiency of the enzyme. The altered dNTP-binding pocket in Q151Mc RT has the Q151-R72 hydrogen bond removed and has a switched conformation for the key conserved residue R72 compared to that in wild-type RT. On the basis of a modeled structure of hepatitis B virus (HBV) polymerase, the residues R72, Y116, M151, and M184 in Q151Mc HIV-1 RT are conserved in wild-type HBV polymerase as residues R41, Y89, M171, and M204, respectively; functionally, both Q151Mc HIV-1 and wild-type HBV are resistant to dideoxynucleoside analogs.

    The - emitter 177 Lu is a promising therapeutic radioisotope for the curative treatment of cancer using labelled proteins. It has a half - life of 6.71 day and maximum and average (3 energies of 421 and 133 keV, respectively, resulting in a short range of irradiation of tissue. The decay is accompanied by the emission of low energy -radiation of 208.3 keV (11%) and 113 keV (6.4%), suitable for simultaneous imaging. Lu can be produced by two different routes, namely, by irradiation of natural Lu 2 O 3 target ( 176 Lu, 2.6%) or enriched (in 176 Lu) Lu 2 O 3 target, and also by irradiation of Yb target (Yb 2 O 3 ) followed by radiochemical separation of Lu from Yb isotopes. The objective of this work is the development of a method of the production of 177 Lu through of the (n, gamma) nuclear reaction, by the direct and indirect method of production. Targets of lutetium oxide and ytterbium oxide were irradiated for evaluation of the activity produced and the chemical separation of lutetium and ytterbium was studied using different ion exchange resins. For the direct method, the best results were obtained using the target Lu 2 O 3 enriched in 39.6%. The best results for the indirect method were achieved with the process of separation using 0.25M - HlBA as eluent. The results showed that it is possible to produce 177 Lu of low specific activity for labeling molecules used for bone pain relief and in radiosynoviortesy. (author)

    In this study, electrochemical, electrochromic and spectroelectrochemical properties of a tert-butylcalix[4]arene bridged bis double-decker lutetium(III) phthalocyanine (Lu{sub 2}Pc{sub 4}2) were investigated explicitly as compared with a tert-butylcalix[4]arene bridged dimeric lutetium(III) phthalocyanine [Lu{sub 2}Pc{sub 2}(OAc){sub 2}1]. Distinctive differences between electrochemical and electrochromic properties of 1 and 2 were detected. Moreover, the properties of 1 and 2 were compared with previously reported S{sub 4}(CH{sub 2}){sub 4} bridged Lu{sub 2}Pc{sub 2}(OAc){sub 2} and Lu{sub 2}Pc{sub 4}. The calixarene bridged phthalocyanine (Pc) compounds, 1 and 2 showed well-defined electrochromic behaviour with green-blue and blue-purple colour transitions. The enhanced electrochromic properties of 2, as compared to 1, were attributed to its double-decker structure, probably allowing the formation of suitable ion channels for the counter ion movement in the solid film.

    New measurements have been undertaken to determine the half-life of {sup 151}Sm. A pure {sup 151}Sm solution was obtained after chemical separation from a samarium solution resulting from the dissolution of an irradiated samarium sample. The concentration of {sup 151}Sm in the solution was measured by mass spectrometry, combined with the isotope dilution technique. The activity of the solution was measured by liquid scintillation counting by six European laboratories as part of an international comparison. These combined results lead to a half-life of T{sub 1/2} = 94.6(6)a.

    We have measured the optical isotope shifts of 146 Sm and 151 Sm by laser resonance fluorescence. From these measurements the changes in the mean square nuclear radii are: delta 2 > (A=144 to 146)=0.266(10) fm 2 , and delta 2 > (A=151 to 152)=0.262(10) fm 2 . These results, together with those of the stable isotopes, show that the average nuclear expansion of samarium can be accounted for by the liquid drop model with deformations. (orig.)

    The neutron radiative capture is a nuclear reaction that occurs in the presence of neutrons on all isotopes and on a wide energy range. The neutron capture range on Lutetium isotopes, presented here, illustrates the variety of measurements leading to the determination of cross sections. These measurements provide valuable fundamental data needed for the stockpile stewardship program, as well as for nuclear astrophysics and nuclear structure. Measurements, made in France or in United-States, involving complex detectors associated with very rare targets have significantly improved the international databases and validated models of nuclear reactions. We present results concerning the measurement of neutron radiative capture on Lu{sup 173}, Lu{sup 175}, Lu{sup 176} and Lu{sup 177m}, the measurement of the probability of gamma emission in the substitution reaction Yb{sup 174}(He{sup 3},p{gamma})Lu{sup 176}. The measurement of neutron cross sections on Lu{sup 177m} have permitted to highlight the process of super-elastic scattering

    Highlights: Black-Right-Pointing-Pointer Uniform and dispersive cubic precursor can be synthesized by sample hydrothermal process. Black-Right-Pointing-Pointer Hydrothermal precursor could transform to Lu{sub 2}O{sub 3}:RE{sup 3+} with its original cubic morphology. Black-Right-Pointing-Pointer Nearly equal intensities of blue, green, and red emissions under single 980 nm laser. Black-Right-Pointing-Pointer Lu{sub 2}O{sub 3}:RE{sup 3+} show bright white light emission, clearly visible to the naked eyes. Black-Right-Pointing-Pointer Chromaticity coordinate is very close to the standard equal energy white light illuminate. - Abstract: Uniform and dispersive Lu{sub 2}O{sub 3}:Yb{sup 3+}/Er{sup 3+}/Tm{sup 3+} nanocubes have been successfully synthesized by hydrothermal process with subsequent calcination at 900 Degree-Sign C. The as-formed RE{sup 3+}-doped lutetium oxide precursor via the hydrothermal process, as a template, could transform to RE{sup 3+}-doped Lu{sub 2}O{sub 3} with their original cubic morphology and slight shrinkage in the size after post-annealing process. The formation mechanism for the lutetium oxide precursor cubes has been proposed. Under single wavelength diode laser excitation of 980 nm, the as-obtained Lu{sub 2}O{sub 3}:3%Yb{sup 3+}/0.5%Er{sup 3+}/0.3%Tm{sup 3+} nanocubes show nearly equal intensities of blue (Tm{sup 3+}: {sup 1}G{sub 4} {yields} {sup 3}H{sub 6}), green (Er{sup 3+}: ({sup 2}H{sub 11/2}, {sup 4}S{sub 3/2}) {yields} {sup 4}I{sub 15/2}), and red (Er{sup 3+}: {sup 4}F{sub 9/2} {yields} {sup 4}I{sub 15/2}) emissions, which produces bright white light emission, clearly visible to the naked eyes. The main pathways to populate the upper emitting states come from the energy-transfer processes from Yb{sup 3+} to Tm{sup 3+}/Er{sup 3+}, respectively. The chromaticity coordinate of the Lu{sub 2}O{sub 3}:3%Yb{sup 3+}/0.5%Er{sup 3+}/0.3%Tm{sup 3+} sample is calculated to be about x = 0.3403 and y = 0.3169, which falls exactly within the

  1. Development of a novel bombesin analog radiolabeled with Lutetium-177: in vivo evaluation of the biological properties in Balb-C mice

    Bombesin (BBN), a 14-aminoacid amphibian peptide homologue of mammalian gastrin-releasing peptide (GRP), has demonstrated the ability to bind with high affinity and specificity to GRP receptor, which are overexpressed on a variety of human cancers. A large number of BBN analogs were synthesized for this purpose and have shown to reduce tumor growth in mice. However, most of the studied analogs exhibit high abdominal accumulation, specially in pancreas. This abdominal accumulation may represent a problem in clinical use of radiolabeled bombesin analogs probably due to serious side effects to patients. In this study we describe the results of radiolabeling with lutetium-177 ( 177 Lu) and in vivo biodistribution and pharmacokinetics studies in normal Balb-C mice of a novel bombesin analog (BBNp4) - DOTA-X-BBN(6-14), where X is a spacer of four aminoacids. This spacer was inserted between the chelator and the binding sequence in order to improve bombesin in vivo properties. BBNp4 was successfully labeled with high yield and kept stable for more than 96 hours at 4 deg C and 4 hours in human plasma. Data analysis obtained from the in vivo studies showed that the amount of BBNp4 present in plasma decreased rapidly and became almost undetectable at 60 min p.i., indicating rapid peptide excretion, which is performed mainly by renal pathway. In addition, biodistribution and single photon emission tomography showed low abdominal accumulation of 177 Lu-DOTA-X-BBN(6-14), indicating that this analog is a potential candidate for tumors target therapy.

    An experiment aiming to search for new isomers in the region of proton emitter 151 Lu was performed at the Accelerator Laboratory of the University of Jyväskylä (JYFL), by combining the high resolution γ-ray array JUROGAM, gas-filled RITU separator and GREAT detectors with the triggerless total data readout acquisition (TDR) system. In this proceeding, we revisit the level scheme of 151 Lu by using the proton-tagging technique. A level scheme consistent with the latest experimental results is obtained, and 3 additional levels are identified at high excitation energies. (author)

  13. Solvent extraction of anionic chelate complexes of lanthanum(III), europium(III), lutetium(III), scandium(III), and indium(III) with 2-thenoyltrifluoroacetone as ion-pairs with tetrabutylammonium ions

    1992-01-01

    The solvent extraction of lanthanum(III), europium(III), lutetium(III), scandium(III), and indium(III) in 0.1 mol dm -3 sodium nitrate solutions with 2-thenoyltrifluoroacetone (Htta) in the absence and presence of tetrabutylammonium ions (tba + ) into carbon tetrachloride was measured. The extraction of lanthanum(III), europium(III), and lutetium(III) was greatly enhanced by the addition of tba + ; this could be explained in terms of the extraction of a ternary complex, M(tta) 4 - tba + . However, the extractions of scandium(III) and indium(III) were nearly the same when tba + was added. The data were treated on the basis of the formation equilibrium of the ternary complex from the neutral chelate, M(tta) 3 , with the extracted ion-pairs of the reagents, tta - tba + , in the organic phase. It was concluded that the degree of association of M(tta) 3 with the ion-pair, tta - tba + , is greater in the order La(tta) 3 ≅ Eu(tta) 3 > Lu(tta) 3 , or that the stability of the ternary complex in the organic phase is higher in the order La(tta) 4 - tba + ≅ Eu(tta) 4 - tba + > Lu(tta) 4 - tba + . This is similar to those of adduct metal chelates of Htta with tributylphosphate (TBP) in synergistic extraction systems. (author)

    1995-08-01

    Following the first report of superdeformed (SD) bands with identical transition energies in the pairs ({sup 151}Tb*,{sup 152}Dy), ({sup 150}Gd*, {sup 151}Tb) and ({sup 153}Dy*, {sup 152}Dy) (where * denotes an excited SD band), it was proposed by Nazarewicz et al. that the observations could be understood in a strong-coupling approach if pseudo SU(3) symmetry were invoked. In this model there are three limiting values of the decoupling parameter; i.e. a = 0, {plus_minus}1. In the first two cases mentioned above the pairs of bands have nearly identical transition energies and are interpreted as proton excitations involving the [200]1/2 pseudospin orbital coupled to the {sup 152}Dy core, for which the value of the decoupling parameter is calculated to be a =+1.

  5. Psalm 151 of the Septuagint: a Subject Analysis

    Directory of Open Access Journals (Sweden)

    Veviurko Il'ia

    2016-01-01

    Full Text Available By its location in the Septuagint canon, Psalm 151 takes up a place of a certain epilogue of the whole Psalter. Due to its isolation in the Greek text and non-canonicity from the masoretic point of view, as well as to its apparent simplicity and triviality, the Psalm was not often attracting attention of the biblical scholars. Only after discovering of a longer Hebrew version of the Psalm in Qumran the situation began to change. Now the Greek Ps 151 has being engaged into comparative study, but generally remaining in the shadow of the Qumran text. This article deals principally with Septuagint version of the Psalm, that underlies the Slavonic and others recensions adopted in the Christian tradition. A through thematical analysis, beginning with the presumption of the texts meaningfulness, will allow then to compare it with the longer Qumran version, the latter to be found poetical interpretation of the former. The analysis reveals David of the Ps 151 to be very much archetypical than historical personality. This is enough to explain the almost complete withdrawal of the emotional «colours», though not depriving the Psalm of its poetical expressiveness. The hero of Ps 151 is a silhouette with some trates of the Anoited One that cometh. This conclusion leads us to the proper estimation of the significance of the Psalm in the history of religious ideas: by the examination of this text we can determine more exactly, what kind of characteristics of the Psalters David collected in its ‘epilogue’ were perceived by the readers as protomessianic: the stainless moral purity, the unfamiliarity to the world, the mysterious conversation with God, the natural possession of power as a mode of the direct divine activity, and the readiness to became a ransomer for the people.

    Malignant gliomas are primary brain tumors, resistant to various treatments, as chemotherapy, radiotherapy, induction of apoptosis and surgery. An alternative for the treatment of malignant gliomas is the radionuclide therapy. This technique apply radiolabeled molecules that selectively bind to tumor cells producing cytotoxic effect by dose irradiation, and resulting in death of tumor cells. Most protocols for radionuclide therapy of malignant brain tumors involve the administration of peptides labeled with {beta}{sup -} emitting radioisotopes. The Substance P (SP) is an 11- amino acid neuropeptide, characterized by the C-terminal sequence Phe-X-Gly-Leu-Met-NH{sub 2}. The use of SP labeled with different radionuclides including {sup 177}Lu, have been proposed for in vivo treatment of tumors. SP is the most important target of neurokinin 1 receptors, over expressed in malignant gliomas. The objective of this work was to study conditions of radiolabeling DOTA-SP with {sup 177}Lu, the stability of labeled compound and in vivo and in vitro, to develop a protocol production and evaluate the potential of the radiopharmaceutical in the therapy of gliomas. The labeling conditions were optimized varying the temperature, reaction time, activity of lutetium-177 chloride and mass of DOTA-SP. The radiochemical purity of preparations were analyzed by chromatographic techniques. The stability of {sup 17L}u -DOTA- SP radiolabeled with low activity of {sup 177}Lu was evaluated for different time at 2-8 degree C or incubated in human serum. The stability of the labeled with high activity of {sup 177}Lu was also analyzed in the presence of gentisic acid (6 mg / mL) added after the labeling reaction. The labeled conditions in low and high activity were subjected to evaluation for the ability to cause oxidation of methionine residue, adding the D-L- methionine amino acid to the reaction medium (6 mg / mL) and subsequent chromatographic evaluation.

    The wealth of data collected in the study of superdeformation in {sup 151}Dy allowed for new information to be obtained on the normally deformed structures in this nucleus. At high spin several new yrast states have been identified for the first time. They were associated with single-particle excitations. Surprisingly, a sequence was identified with energy spacings characteristic of a rotational band of normal ({beta}2 {approximately} 0.2) deformation. The bandhead spin appears to be 15/2{sup -} and the levels extend up to a spin of 87/2{sup -}. A clear backbend is present at intermediate spins. While a similar band based on a bandhead of 6{sup +} is known in {sup 152}Dy, calculations suggest that this collective prolate band should not be seen in {sup 151}Dy. In the experiment described earlier in this report that is aimed at determining the deformations associated with the SD bands in this nucleus and {sup 152}Dy, the deformation associated with this band will be determined. This will provide further insight into the origin of this band.

    The National Council on Radiation protection and Measurements (NCRP) has recently published its Report No. 151, which presents recommendations and technical information on the design of structural shielding for megavoltage X and gamma-ray radiotherapy facilities. The calculations method introduced by this Report covers aspects like IMRT and other special techniques, as well as the design of structural details like doors, mazes and ducts, or the calculations of skyshine and ground shine radiation. In this work the necessary shielding for a Siemens Oncor treatment unit has been calculated, following NCRP Report No. 151 and DIN 6847-2 standard. In both cases the same isocenter workload W, use factor U, occupancy factor T and shielding design goals P, for workers and public members, are used. The results obtained with DIN 6847 are similar to the ones obtained with this Report, though there are some differences when considering the in-any-one-hour time averaged dose-equivalent rate in low occupancy factor areas, or where scattered radiation reaches the barrier under a small angle.

    Matrix metalloproteinase-7 (MMP-7) (also known as matrilysin-1) is secreted as a proenzyme (proMMP-7) and plays a key role in the degradation of various extracellular matrix (ECM) and non-ECM molecules after activation. To identify the binding proteins related to proMMP-7 activation, a human lung cDNA library was screened by yeast two-hybrid system using proMMP-7 as bait. We identified a candidate molecule CD151, which is a member of the transmembrane 4 superfamily. Complex formation of proMMP-7 with CD151 was demonstrated by immunoprecipitation of the molecules from CaR-1 cells, a human rectal carcinoma cell line, expressing both proMMP-7 and CD151, and CD151 stable transfectants incubated with proMMP-7. Yeast two-hybrid assays using deletion mutants of proMMP-7 and CD151 suggested an interaction between the propeptide of proMMP-7 and the COOH-terminal extracellular loop of CD151. The binding activity of (125)I-labeled proMMP-7 to CD151 on the cell membranes was shown with CD151 stable transfectants. Laser-scanning confocal microscopy demonstrated that proMMP-7 colocalizes with CD151 on the cell membranes of CD151 stable transfectants and CaR-1 cells. In situ zymography using crosslinked carboxymethylated transferrin, a substrate of MMP-7, demonstrated proteinase activity on and around CD151 stable transfectants and CaR-1 cells, while the activity was abolished by their treatment with MMP inhibitors, anti-MMP-7 antibody or anti-CD151 antibody. In human lung adenocarcinoma tissues, colocalization of MMP-7 and CD151 was demonstrated on the carcinoma cells. Metalloproteinase activity was present in these tissues and could be inhibited by antibodies to MMP-7 or CD151. These data demonstrate for the first time that proMMP-7 is captured and activated on the cell membranes through interaction with CD151, and suggest the possibility that similar to the MT1-MMP/MMP-2 system, MMP-7 is involved in the pericellular activation mechanism mediated by CD151, a crucial step in

    Structure of eight superdeformed bands in the nucleus {sup 151}Tb is analyzed using the results of the Hartree-Fock and Woods-Saxon cranking approaches. It is demonstrated that far going similarities between the two approaches exit and predictions related to the structure of rotational bands calculated within the two models are nearly parallel. An interpretation scenario for the structure of the superdeformed bands is presented and predictions related to the exit spins are made. Small but systematic discrepancies between experiment and theory, analyzed in terms of the dynamical moments, J{sup (2)}, are shown to exist. The pairing correlations taken into account by using the particle-number-projection technique are shown to increase the disagreement. Sources of these systematic discrepancies are discussed - they are most likely related to the yet not optimal parametrization of the nuclear interactions used. (authors). 60 refs.

    The nucleus of {sup 151}Sm, which has 89 neutrons, happens to be on the lower edge of the deformed nuclei of region II. Therefore, the study of its levels is very interesting for the verification of the goodness of the collective models for deformed nuclei when the deformation is small (we introduce these models in the first chapter). {sup 151}Sm has often been studied, but the direct gamma spectrum measured with a lithium drift-germanium detector (chapter 3) shows many high energy transitions which did not appear in the previous level schemes. In order to settle these transitions, we have undertaken gamma-gamma coincidence spectra (as well as sum-coincidence spectra) experiments with a scintillation spectrometer designed in our laboratory (chapter 2). The investigation of the intensities of these coincidences leads us to modify the last proposed level schemes: we suppress the levels at 405,5 and 650 keV, we add levels at 245,6 - 306,6 - 522 - 952 and 962 keV. We have also verified the multipolarities of the main transitions and measured the half-lives of a few levels (chapter 3) (we find a half-life of 1.1 {+-} 0.5 nanosecond for the level at 167,7 keV). In chapter 4, we compare our results to the predictions of the models described in chapter 1. (author) [French] Le noyau de {sup 151}Sm, qui possede 89 neutrons, se trouve a la limite inferieure des noyaux deformes de la region II. L'etude de ses niveaux excites est donc d'un interet tout particulier pour la verification de la validite des differents modeles collectifs pour les noyaux deformes, lorsque la deformation est petite (nous introduisons ces modeles dans un premier chapitre). Le {sup 151}Sm a deja fait l'objet de nombreuses etudes, mais le spectre gamma direct fait avec une jonction de germanium compense au lithium (chapitre 3), nous a montre l'existence d'un grand nombre de transitions de hautes energies qui ne sont pas placees dans les schemas proposes jusqu'a ce jour.

The solubility diagrams (pLu{sub (ac)}-pC{sub H}) by means of a radiochemical method were obtained, and starting from its the pC{sub H} values that limit the saturation and no-saturation zones of the solutions were settled down. Those diagrams allowed, also, to calculate the solubility product constants of Lu(OH){sub 3}. The experimental data to the polynomial solubility equation were adjusted, what allowed to calculate those values of the solubility product constants of Lu(OH){sub 3} and to determine the first hydrolysis constant. The value of precipitation pC{sub H} diminishes when the initial concentration of the lutetium increases, while the values of K{sub ps} and {beta}{sub 1,H} its remain constant. (Author)

    Gamma rays decaying from the excited states of the proton-unbound 151 Lu were observed for the first time in an experiment using the 96 Ru( 58 Ni,p2n) 151 Lu reaction. These γ rays were identified by correlating prompt γ radiations at the target position with 151 Lu proton radioactivities at the focal plane of a recoil mass separator. Systematic data on N=80 isotones suggest a possible isomeric level at high spin in 151 Lu. Our measurement was unable to observe such an isomer, but provided an upper limit on its half-life. The observed γ rays in 151 Lu can be interpreted in terms of two possible level structures. copyright 1998 The American Physical Society

Lattice dynamic behaviors of Eu and Fe atom in the complexes were investigated by Moessbauer spectroscopy. By {sup 151}Eu-Moessbauer spectrum and parameters of new complexes, bpy complex showed the largest quadrupole splitting value, indicating bad symmetry of Eu ligand in the environment. Molecular structure of napy, bpy and phen complex were shown. These complexes are consisted of Eu atom coordinated with ligand and water molecule, of which (Fe(CN){sub 6}){sup 3-} ion formed one dimentional polymer chain and naphthyridines formed stacking structure. New complexes were observed by {sup 57}Fe-Moessbauer spectroscopy, too. The quadrupole splitting values were very different each other, indicating change of symmetry of Fe atom in the environment and three valence low spin state of Fe in the complex. (S.Y.)

    The solvent extractions of lanthanum(III), europium(III), and lutetium(III) (M 3+ ) in 0.1 moldm -3 sodium nitrate solutions with 5,7-dichloro-8-quinolinol (HA) into chloroform were studied in both the absence and presence of tetrabutylammonium ions (tba + ) or trioctylphosphine oxide (TOPO). In the absence of tba + or TOPO, the extracted species were the MA 3 and MA H A (self-adduct), though MA 4 - tba + was found when tba + was added; MA 3 TOPO and MA 3 (TOPO) 2 were found when TOPO was added in addition to the above mentioned two species. The anionic complex or TOPO adducts greatly enhanced the extraction. The data were statistically analyzed and the equilibrium constants for the extraction of these species, as well as the constants for the association of the HA, the A - tba + , or the TOPO on the MA 3 in the organic phase, were determined. The extraction of the MA 3 is better in the order LaA 3 3 3 . Although the values of the association constant of the HA or the TOPO on the MA 3 are rather similar for the three metal chelates, the constants for A - tba + are larger in the same order as mentioned above. Thus, the separation of these three metal ions by solvent extraction with this chelating extractant is not much affected by the addition of TOPO, but is greatly improved by the addition of tba + .

    Despite advances in our understanding of the mechanisms of influenza A virus (IAV) infection, the crucial virus-host interactions during the viral replication cycle still remain incomplete. Tetraspanin CD151 is highly expressed in the human respiratory tract, but its pathological role in IAV infection is unknown. We sought to characterize the functional role and mechanisms of action of CD151 in IAV infection of the upper and lower respiratory tracts with H1N1 and H3N2 strains. We used CD151-null mice in an in vivo model of IAV infection and clinical donor samples of in vitro-differentiated human nasal epithelial cells cultured at air-liquid interface. As compared with wild-type infected mice, CD151-null infected mice exhibited a significant reduction in virus titer and improvement in survival that is associated with pronounced host antiviral response and inflammasome activation together with accelerated lung repair. Interestingly, we show that CD151 complexes newly synthesized viral proteins with host nuclear export proteins and stabilizes microtubule complexes, which are key processes necessary for the polarized trafficking of viral progeny to the host plasma membrane for assembly. Our results provide new mechanistic insights into our understanding of IAV infection. We show that CD151 is a critical novel host factor of nuclear export signaling whereby the IAV nuclear export uses it to complement its own nuclear export proteins (a site not targeted by current therapy), making this regulation unique, and holds promise for the development of novel alternative/complementary strategies to reduce IAV severity.

  11. Determination of the constants of the solubility product of Ln(OH)3 and the effect of the chloride ions on the lanthanum hydrolysis, praseodymium and lutetium in aqueous solutions of ion force 2 Molar

    The behavior of lanthanum (III), praseodymium (III), and lutetium (III) was studied in 2 M NaClO 4 (aq) and 2 M NaCl (aq) at 303 K and free -CO 2 conditions. Solubility diagrams (p Ln(aq)-pC H ) were obtained by means of a radiochemical method. The pC H borderlines of saturation and unsaturation zones of the solutions and solubility product constants for Ln(OH) 3 were determined from these diagrams. The fitting of the solubility equation to the experimental values of p Ln(aq)-pC H diagrams allowed the calculation of the first hydrolysis and solubility product constants. Independently, the stability constants for the first species of hydrolysis were determined by means of pH titrations, the data were treated with the program SUPERQUAD and fitted to the mean ligand number equation. The stability constants for the species LnCl 2+ were as well calculated in 2M ionic strength and 303 K from the hydrolysis constant values obtained in both perchlorate and chloride media. The values obtained for La, Pr and Lu were: logK ps : 21.11 ± 0.09, 19.81 ± 0.11 and 18.10 ± 0.13 in 2M NaClO 4 ; logK ps : 22.22 ± 0.09, 21.45 ± 0.14 and 18.52 ± 0.29 in 2M NaCl; log β 1 : - 8.64 ± 0.02, - 8.37 ± 0.01 and - 7.95 ± 0.11 in 2M NaClO 4 ; log β 1 / : - 9.02 ± 0.11, - 8.75 ± 0.01 and - 8.12 ± 0.03 in 2M NaCl and the values for log β 1,Cl were - 0.0255, - 0.155 and - 0.758, respectively.

    The stability constants of La{sup 3+}, Pr{sup 3+}, Eu{sup 3+}, Er{sup 3+} and Lu{sup 3+} chloride complexes were determined in perchloric acid media using a liquid-liquid extraction method. The dinonyl napthalene sulfonic acid in n-heptane was used as extractant. The lanthanide (Ln) concentrations were measured by a radiochemical (Eu and Lu) and a spectrophotometric (La, Pr, and Er) methods. In the last method, xylenol orange was used for the determinations at ph 6. The stability constants of lanthanum, praseodymium, erbium and lutetium chloride complexes were determined in 2, 3 and 4 M ionic strength and europium in 1, 2 and 3 M, at 303 K. The fitting of experimental data to the equations for the calculation of the stability constants, was carry out considering both one chemical species (LnCl{sup 2+}) or two chemical species (LnCl{sup 2+} and LnCl{sub 2}{sup +}). The Specific Ion Interaction Theory was applied to the values of log {beta}{sup I}{sub Ln},{sub Cl} and the first stability constants at zero ionic strength were calculated by extrapolation. The same theory could not be applied to the log {beta}{sup I}{sub Ln},{sub 2Cl}, due to its low abundance and the values determined for the stability constants were similar. The distribution diagrams of the chemical species were obtained using the program MEDUSA and considering log {beta}{sup I}{sub Ln},{sub CI}, log {beta}{sup I}{sub Ln},{sub 2CI} values obtained in this work and the hydrolysis constants taken from the literature. The lanthanide chloride complexes are present in solution at specific conditions of ionic strength, concentration and in the absence of hydrolysis. The log {beta}{sup I}{sub Ln},{sub Cl} data were related to the charge density and the corresponding equations were obtained. These equations could be used to determine the stability constants along the lanthanide series. (Author)

  15. Characterisation of pks15/1 in clinical isolates of Mycobacterium tuberculosis from Mexico

    Directory of Open Access Journals (Sweden)

    2013-09-01

    Full Text Available Tuberculosis (TB is an infectocontagious respiratory disease caused by members of the Mycobacterium tuberculosis complex. A 7 base pair (bp deletion in the locus polyketide synthase (pks15/1 is described as polymorphic among members of the M. tuberculosis complex, enabling the identification of Euro-American, Indo-Oceanic and Asian lineages. The aim of this study was to characterise this locus in TB isolates from Mexico. One hundred twenty clinical isolates were recovered from the states of Veracruz and Estado de Mexico. We determined the nucleotide sequence of a ± 400 bp fragment of the locus pks15/1, while genotypic characterisation was performed by spoligotyping. One hundred and fifty isolates contained the 7 bp deletion, while five had the wild type locus. Lineages X (22%, LAM (18% and T (17% were the most frequent; only three (2% of the isolates were identified as Beijing and two (1% EAI-Manila. The wild type pks15/1 locus was observed in all Asian lineage isolates tested. Our results confirm the utility of locus pks15/1 as a molecular marker for identifying Asian lineages of the M. tuberculosis complex. This marker could be of great value in the epidemiological surveillance of TB, especially in countries like Mexico, where the prevalence of such lineages is unknown.

    Single crystals of {sup 151}Eu:YAG were grown by the vertical Bridgman method using Eu{sub 2}O{sub 3} with isotopic enrichment of {sup 151}Eu of 97.5%. Additional Hf{sup 4+}or Si{sup 4+} ions were introduced to favor a high concentrations of Eu{sup 2+}. As compared to Eu:YAG with natural isotope composition, the EPR spectra of YAG doped with {sup 151}Eu isotope show a reduced number of hyperfine structure components and a well-resolved structure of a bigger number of electronic transitions. Optical properties of obtained crystals and the effects of heat treatments under oxidizing and reducing conditions are reported. Based on the analysis of Eu{sup 3+} distribution in oxidized Eu,Hf:YAG, in comparison to that in Eu:YAG, the concentration of Eu{sup 2+} in as-grown Eu,Hf:YAG is determined. - Highlights: • YAG:Eu,Hf single crystals containing only {sup 151}Eu isotopes were prepared. • isotopic enriched crystals gave a well-resolved EPR hyperfine structure of Eu{sup 2+} centers. • the redox ratio was followed through the Eu{sup 2+} associated absorption band at 250 nm. • the band intensities at 378 nm correlate with the Eu{sup 2+} concentration.

    Instrumental neutron activation analysis was used to study accumulation of Hg(II) and Cr(VI) ions in Arthrobacter globiformis 151B, a gram-positive, Cr(VI)-reducer aerobic bacterium isolated from basalt sample taken from the most polluted region in the Republic of Georgia (Kazreti). Experiments were focused on (1) accumulation of Hg(II) in bacterial cells; (2) accumulation of Cr(VI) in A. globiformis 151B in the presence of Hg(II) and (3) effects of Hg(II) and mixture of Cr(VI)-Hg(II) on the elemental composition of bacteria. It was shown that this bacterial strain possesses uptake mechanisms by which mercury toxicity can be reduced in environment and that accumulation of Cr(VI) in A. globiformis 151B is much higher in the presence of Hg(II) ions. Accumulation of Hg(II), similar to the Cr(VI) accumulation, follows well the Lengmuir-Freundlich model. NAA measurements showed increased content of Fe in bacteria under Hg and Cr action, suggesting that Fe-containing biomolecules play a decisive role in detoxifying of heavy metals by A. globiformis 151B. A concentration of 5000 μg/L of Hg(II) was found to be critical for A. globiformis 151B. At this concentration of Hg(II) the concentrations of both essential (Na, Mg, Al, Cl, K, Mn, Zn) and some non-essential elements (Rb, Sb, Sc, As) changed drastically along with a decrease of the biomass of bacteria by a factor of two. One may assume that under this high exposure to Hg(II) the structure of the bacterial cell wall was destroyed. (author)

    Bombesin (BBN) receptors - in particular, the gastrin-releasing peptide (GRP) receptor peptide - have been shown to be massively over expressed in several human tumors types, including prostate cancer, and could be an alternative as target for its treatment by radionuclide therapy (RNT). A large number of BBN analogs had already been synthesized for this purpose and have shown to reduce tumor growth in mice. Nevertheless, most of the studied analogs exhibit high abdominal accumulation, especially in pancreas. This abdominal accumulation may represent a problem in clinical use of radiolabeled bombesin analogs probably due to serious side effects to patients. The goal of the present work was to radiolabel a novel series of bombesin derivatives with lutetium-177 and to evaluate the relationship between their structure and diagnostic-therapeutic activity for prostate tumor. The generic structure of studied peptides is DOTA-Phe-(Gly){sub n}-BBN(6-14), where DOTA is the chelator, n is the number of glycine amino acids of Phe-(Gly){sub n} spacer and BBN(6-14) is the bombesin sequence from the amino acid 6 to the amino acid 14. Preliminary studies were done to establish the ideal labeling conditions for obtaining the highest yield of labeled bombesin derivatives, determined by instant thin layer chromatography (ITLC-SG) and high performance liquid chromatography (HPLC). The stability of the preparations was evaluated either after storing at 2-8 degree C or incubation in human serum at 37 degree C and the partition coefficient was determined in n:octanol:water. In vivo studies were performed in both healthy Balb-c and Nude mice bearing PC-3 xenografts, in order to characterize the biological properties of labeled peptides. In vitro studies involved the evaluation of cold bombesin derivatives effect in PC-3 cells proliferation. Bombesin derivatives were successfully labeled with high yield at optimized conditions and exhibited high stability at 4 degree C. The analysis of

Four different sources of this psalm in Syriac can be distinguished, namely, a commentary on the psalms by Athanasius, a number of inanuscripts of the Peshitta and the Syrohexaplar, the manuscript 12t4 (containing the five Syriac apocryphal psalms as an addendum to the canonical psalms and a number of other manuscripts with these apocryphal psalms. This psalm existed in more than one version in Hebrew. One version is reflected at Qumran in the psalms Scroll from cave 11 and another one in the Septuagint. The Syriac is dependent on the Greek, but clear signs of an inner-Syriac development can be discerned.

  1. Kinetic, Spectroscopic, and X-ray Crystallographic Characterization of the Functional E151H Aminopeptidase from Aeromonas proteolytica.

    Glutamate151 (E151) has been shown to be catalytically essential for the aminopeptidase from Vibrio proteolyticus (AAP). E151 acts as the general acid/base during the catalytic mechanism of peptide hydrolysis. However, a glutamate residue is not the only residue capable of functioning as a general acid/base during catalysis for dinuclear metallohydrolases. Recent crystallographic characterization of the D-aminopeptidase from Bacillus subtilis (DppA) revealed a histidine residue that resides in an identical position to E151 in AAP. Because the active-site ligands for DppA and AAP are identical, AAP has been used as a model enzyme to understand the mechanistic role of H115 in DppA. Substitution of E151 with histidine resulted in an active AAP enzyme exhibiting a k{sub cat} value of 2.0 min{sup -1}, which is over 2000 times slower than r AAP (4380 min{sup -1}). ITC experiments revealed that Zn{sup II} binds 330 and 3 times more weakly to E151H-AAP compared to r-AAP. UV-vis and EPR spectra of Co{sup II}-loaded E151H-AAP indicated that the first metal ion resides in a hexacoordinate/pentacoordinate equilibrium environment, whereas the second metal ion is six-coordinate. pH dependence of the kinetic parameters k{sub cat} and K{sub m} for the hydrolysis of L-leucine p-nitroanilide (L-pNA) revealed a change in an ionization constant in the enzyme-substrate complex from 5.3 in r-AAP to 6.4 in E151H-AAP, consistent with E151 in AAP being the active-site general acid/base. Proton inventory studies at pH 8.50 indicate the transfer of one proton in the rate-limiting step of the reaction. Moreover, the X-ray crystal structure of [ZnZn(E151H-AAP)] has been solved to 1.9 {angstrom} resolution, and alteration of E151 to histidine does not introduce any major conformational changes to the overall protein structure or the dinuclear Zn{sup II} active site. Therefore, a histidine residue can function as the general acid/base in hydrolysis reactions of peptides and, through analogy of

    The {sup -} emitter {sup 177} Lu is a promising therapeutic radioisotope for the curative treatment of cancer using labelled proteins. It has a half - life of 6.71 day and maximum and average (3 energies of 421 and 133 keV, respectively, resulting in a short range of irradiation of tissue. The decay is accompanied by the emission of low energy -radiation of 208.3 keV (11%) and 113 keV (6.4%), suitable for simultaneous imaging. Lu can be produced by two different routes, namely, by irradiation of natural Lu{sub 2}O{sub 3} target ({sup 176}Lu, 2.6%) or enriched (in {sup 176}Lu) Lu{sub 2}O{sub 3} target, and also by irradiation of Yb target (Yb{sub 2}O{sub 3}) followed by radiochemical separation of Lu from Yb isotopes. The objective of this work is the development of a method of the production of {sup 177} Lu through of the (n, gamma) nuclear reaction, by the direct and indirect method of production. Targets of lutetium oxide and ytterbium oxide were irradiated for evaluation of the activity produced and the chemical separation of lutetium and ytterbium was studied using different ion exchange resins. For the direct method, the best results were obtained using the target Lu{sub 2}O{sub 3} enriched in 39.6%. The best results for the indirect method were achieved with the process of separation using 0.25M - HlBA as eluent. The results showed that it is possible to produce {sup 177} Lu of low specific activity for labeling molecules used for bone pain relief and in radiosynoviortesy. (author)

The Eu partial phonon density of states (DOS) in Eu 3 Pd 20 Ge 6 are investigated using 151 Eu nuclear resonance inelastic scattering (NRIS). 151 Eu NRIS was carried out at BL09XU of SPring-8. Significant temperature dependence was found in the partial phonon DOS. Judging from the valence change at the Eu 4a site and the comparison with the ab initio calculation of Eu 3 Pd 20 Ge 6 , the change of the Eu DOS is caused by the electronic states. On the other hand, significant acoustic contribution was found even at the guest site of the Eu ones. In addition, slower average velocity than transverse sound velocity was obtained by Eu partial phonon DOS. Considering that heat is carried by the acoustic phonon in materials, the present results demonstrate that the moderate thermal insulation in Eu 3 Pd 20 Ge 6 is connected with the observation of slow average sound velocity at the Eu sites.

    Full Text Available Abstract Removal of synthetic dyes is one of the main challenges before releasing the wastes discharged by textile industries. Biodegradation of azo dyes by alkaliphilic bacterial consortium is one of the environmental-friendly methods used for the removal of dyes from textile effluents. Hence, this study presents isolation of a bacterial consortium from soil samples of saline environment and its use for the decolorization of azo dyes, Direct Blue 151 (DB 151 and Direct Red 31 (DR 31. The decolorization of azo dyes was studied at various concentrations (100–300 mg/L. The bacterial consortium, when subjected to an application of 200 mg/L of the dyes, decolorized DB 151 and DR 31 by 97.57% and 95.25% respectively, within 5 days. The growth of the bacterial consortium was optimized with pH, temperature, and carbon and nitrogen sources; and decolorization of azo dyes was analyzed. In this study, the decolorization efficiency of mixed dyes was improved with yeast extract and sucrose, which were used as nitrogen and carbon sources, respectively. Such an alkaliphilic bacterial consortium can be used in the removal of azo dyes from contaminated saline environment.

  6. miR-151-3p Targets TWIST1 to Repress Migration of Human Breast Cancer Cells.

    Full Text Available TWIST1 is a highly conserved basic helix-loop-helix transcription factor that contributes to cancer metastasis by promoting an epithelial-mesenchymal transition and repressing E-cadherin gene expression in breast cancer. In this study, we explored the potential role of miR-151 in TWIST1 expression and cancer properties in human breast cancer cells. We found that the human TWIST1 3'UTR contains a potential binging site for miR-151-3p at the putative target sequence 5'-CAGUCUAG-3'. Using a TWIST1-3'UTR luciferase reporter assay, we demonstrated that the target sequence within the TWIST1 3'UTR is required for miR-151-3p regulation of TWIST1 expression. Moreover, we found that ectopic expression of miR-151-3p by infection with adenoviruses expressing miR-151 significantly decreased TWIST1 expression, migration and invasion, but did not affect cell growth and tumorsphere formation of human breast cancer cells. In addition, overexpression of the protein coding region without the 3'UTR of TWIST1 reversed the repression of cell migration by miR-151-3p. Furthermore, knockdown of miR-151-3p increased TWIST1 expression, reduced E-cadherin expression, and enhanced cell migration. In conclusion, these results suggest that miR-151-3p directly regulates TWIST1 expression by targeting the TWIST1 3'UTR and thus repressing the migration and invasion of human breast cancer cells by enhancing E-cadherin expression. Our findings add to accumulating evidence that microRNAs are involved in breast cancer progression by modulating TWIST1 expression.

    Eu 3+ in ca. 10 wt% europium-exchanged Y-zeolite is partially reduced by treatment in hydrogen at 600 C to Eu 2+ . The reduction of Eu 3+ is more readily achieved in Y-zeolite than in europium(III) oxide. The discrepancy in the extent of reduction as revealed by 151 Eu Moessbauer spectroscopy and near edge X-ray absorption fine structure (XANES) is associated with any difference in the recoil free fractions of Eu 2+ and Eu 3+ which may exist at 298 K and the enhanced sensitivity of the XANES to changes in the europium oxidation state.

    The methodology proposed by the National Council on Radiation Protection 151 (NCRP 151), relates technical information necessary to structural shielding design and evaluation for megavoltage X- and gamma- ray radiotherapy facilities. However, many parameters used to calculate the shield are based on estimates, and may not be adequate to the Brazilian reality. Thus, the central idea of this study is to obtain parameters and is to outline a profile closer to the treatments carried out in facilities in Brazil, through a data collection routine of the Department of Radiotherapy Service of the Real e Benemerita Associacao Portuguesa de Beneficencia, in particular the cobalt therapy Theratron 780 (Atomic Energy of Canada Ltd.) and the linear accelerator Varian Clinac 2100C for measurement of workload, use factor, number of patients, fields, dose and anatomic region treated. So, the work did not draw definite values of the parameters, but indicative values were obtained which showed the importance to carry out more detailed studies of the recommended values. (author)

    The Seyfert 1 galaxy Arp 151 was monitored as part of three reverberation mapping campaigns spanning 2008–2015. We present modeling of these velocity-resolved reverberation mapping data sets using a geometric and dynamical model for the broad-line region (BLR). By modeling each of the three data sets independently, we infer the evolution of the BLR structure in Arp 151 over a total of 7 yr and constrain the systematic uncertainties in nonvarying parameters such as the black hole mass. We find that the BLR geometry of a thick disk viewed close to face-on is stable over this time, although the size of the BLR grows by a factor of ∼2. The dynamics of the BLR are dominated by inflow, and the inferred black hole mass is consistent for the three data sets, despite the increase in BLR size. Combining the inference for the three data sets yields a black hole mass and statistical uncertainty of log10({M}BH}/{M}ȯ ) = {6.82}-0.09+0.09 with a standard deviation in individual measurements of 0.13 dex.

    Compete text of publication follows. The astrophysical γ-process is the main production mechanism of the p-isotopes, the heavy, proton-rich nuclei not produced by neutron capture reactions in the astrophysical sand r-processes. The γ-process is a poorly known process of nucleosynthesis, the models are not able to reproduce well the p-isotope abundances observed in nature. Experimental data on nuclear reactions involved in γ-process reaction networks are clearly needed to provide input for a more reliable γ-process network calculation. As a continuation of our systematic study of reactions relevant for the γ-process, the cross sections of the 151 Eu(α, γ) 155 Tb and 151 Eu(α,n) 154 Tb reactions have been measured. These reactions have been chosen because α-induced cross section data in the region of heavy p-isotopes are almost completely missing although the calculations show a strong influence of these cross section on the resulting abundances. Since the reaction products of both reactions are radioactive, the cross sections have been measured using the activation technique. The targets have been prepared by evaporating Eu 2 O 3 enriched to 99.2% in 151 Eu onto thin Al foils. The target thicknesses have been measured by weighing and Rutherford Backscattering Spectroscopy. The targets have been irradiated by typically 1-2 μA intensity α-beams from the cyclotron of ATOMKI. The investigated energy range between 12 and 17 MeV was covered with 0.5 MeV steps. This energy range is somewhat higher than the astrophysically relevant one, but the cross section at astrophysical energies is so low that the measurements are not possible there. The γ- activity of the reaction products has been measured by a shielded HPGe detector. The absolute efficiency of the detector was measured with several calibration sources. Since 154 Tb has two long lived isomeric states, partial cross sections of the 151 Eu(α,n) 154 Tb reaction leading to the ground and isomeric states

    Objective: Our previous studies showed that CD151 could promote neovascularization in a rat hind-limb ischemia model and in a rat myocardial ischemia model. This study was to determine the change of myocardial perfusion and coronary collateralization after intramyocardial administration CD151 in swines with experimental myocardial infarction. Methods: CD151 and antiCD151 were constructed into the recombinant adeno-associated virus vector (rAAV). Twenty swines received coronary artery ligation and intramuscular injection of rAAV-CD151 or rAAV-green fluorescent protein (GFP). Eight weeks after vector administration, the expression of CD151 protein and the capillary density were measured using immunohistochemistry. Regional myocardial perfusian was evaluated by 13 N-NH 3 PET. Coronary angiography was per-formed to assess collateral vessels reconstruction. The t-test or ANOVA with SPSS 11.0 was used for data analysis. Results: High levels of CD151 protein expression and capillary density were detected in the rAAV-CD151 group. 13 N-NH 3 PET imaging showed that myocardial perfusion was improved and the myocardial ischemia scores were significantly decreased in the rAAV-CD151 group when compared with rAAV-GFP group (10.82 ± 2.36 vs 19.33 ± 1.67, t=5.86, P=0.002).Coronary angiography confirmed better collateral circulation in the rAAV-CD151 group. Conclusions: rAAV-CD151 direct injection can transfect the myocardium and express the CD151 protein, thereby significantly improve the myocardial blood perfusion and coronary collateralization. 13 N-NH 3 PET and coronary angiography can be used directly to evaluate the col-lateral vessel reconstruction and perfusion status of swine myocardium.

    LSD was introduced in psychiatry in the 1950s. Between 1960 and 1973, nearly 400 patients were treated with LSD in Denmark. By 1964, one homicide, two suicides and four suicide attempts had been reported. In 1986 the Danish LSD Damages Law was passed after complaints by only one patient. According to the Law, all 154 applicants received financial compensation for LSD-inflicted harm. The Danish State Archives has preserved the case material of 151 of the 154 applicants. Most of the patients suffered from severe side effects of the LSD treatment many years afterwards. In particular, two-thirds of the patients had flashbacks. With the recent interest in LSD therapy, we should consider the neurotoxic potential of LSD. © The Author(s) 2016.

    Lumbar spondylolysis (LS) has been the subject of several studies focusing on adolescent athletes. Few, if any, studies have examined LS in the general population. Lysis of the pars interarticularis of the vertebra may be associated with slipping (olisthesis), or it may be stable. In the present...... survey of lumbar radiographs and general epidemiological data recorded from the Copenhagen Osteoarthritis Study cohort of 4.151 subjects (age range, 22-93 years), we identified the distribution and individual risk factors for LS-development.

    In recent years, the progress experienced in cancer treatment with ionizing radiation can deliver higher doses to smaller volumes and better shaped, making it necessary to take into account new aspects in the calculation of structural barriers. Furthermore, given that forecasts suggest that in the near future will install a large number of accelerators, or existing ones modified, we believe a useful tool to estimate the thickness of the structural barriers of treatment rooms. The shielding calculation methods are based on standard DIN 6847-2 and the recommendations given by the NCRP 151. In our experience we found only estimates originated from the DIN. Therefore, we considered interesting to develop an application that incorporates the formulation suggested by the NCRP, together with previous work based on the rules DIN allow us to establish a comparison between the results of both methods.

    To determine factors associated with sudden acquired retinal degeneration syndrome (SARDS) diagnosed within one referral population. 151 dogs diagnosed with SARDS. Breed, age, sex, and body weight were compared between dogs with electroretinogram-confirmed SARDS and dogs presented to the UC Davis Veterinary Medical Teaching Hospital (UCD-VMTH) from 1991 to 2014. SARDS was diagnosed in 151 dogs, representing 1.3% of dogs presented to the UCD-VMTH for ophthalmic disease. Although dogs of 36 breeds were affected, the Dachshund (n = 31, 21%), Schnauzer (16, 11%), Pug (11, 7%), and Brittany (5, 3%) were significantly overrepresented, and the Labrador Retriever (3, 2%) was significantly underrepresented vs. the reference population (P < 0.001). Median (range) age and body weight of affected vs. reference dogs were 8.9 (3-20) vs. 6.8 (0.1-26) years and 12.4 (2.8-52.7) vs. 22.3 (0.1-60) kg, respectively. Dogs 6-10 years of age and between 10-20 kg in body weight were significantly overrepresented in the SARDS population, while dogs <6 years of age were significantly underrepresented (P < 0.01). Spayed females (59% of affected dogs) were significantly overrepresented compared to the reference population, whereas intact females (1% of affected dogs) were significantly underrepresented. Consistent with previous studies, smaller, middle-aged, spayed female dogs may be at increased risk of developing SARDS. Unlike previous studies, this is the first study comparing a variety of SARDS-affected breeds to a reference population. Potentially increased risk of SARDS in several breeds, particularly Dachshunds, suggests a familial factor that warrants further investigation using genetic techniques. © 2017 American College of Veterinary Ophthalmologists.

    The aim of this work is the study of {sup 151}Tb and {sup 152}Tb nuclei submitted to increasing speeds using the EUROGAM (phase I) multi-detector. The production of high angular momentum excited nuclei is obtained during {sup 130}Te({sup 27}Al,xn) fusion-evaporation reaction with a 154 MeV bombardment energy. For {sup 151}Tb nucleus, the diagram of high spin normal deformation levels is first determined to allow the analysis of bonds between SD structures and normally deformed states. In addition to the two SD bands already described for {sup 151}Tb nucleus, 8 new SD bands are described (6 for {sup 151}Tb nucleus and 2 for {sup 152}Tb nucleus) using triple and quadruple events analysis. The SD structure analysis gives important informations about nuclear superdeformation in this mass region, in particular about SD bands de-excitation, intrinsic configuration in the second potential well, and gamma transition energy degeneration between twin SD bands. A detailed description of EUROGAM 4{pi}{gamma} multi-detector (phase I and II), which comprises 42 Ge detectors with Compton suppression, is given. (J.S.). 98 refs., 100 figs., 22 tabs.

    Objective To observe the effect of microRNA-151a-3p (miR-151a-3p) up-regulation on the proliferation and migration of prostate cancer cells and explore the possible molecular mechanism. Methods The expression of miR-151a-3p in PC-3M, C4-2B, 22RV1, DU-145, PC-3, LNCap human prostate cancer cells and RWPE-1 human normal prostate epithelial cells was detected by real-time fluorescence quantitative PCR. PC-3 cells with the lowest expression of miR-151a-3p were used for subsequent experiments. Bioinformatics and dual-luciferase reporter assay were performed to predict and test potential target genes of miR-151a-3p. The miR-151a-3p mimics or negative control microRNAs (miR-NCs) were transfected into PC-3 cells. Real-time fluorescence quantitative PCR was used to detect the expression of miR-151a-3p and potential target gene mRNA. The protein expressions of target genes and downstream signaling pathway proteins were analyzed by Western blotting. The proliferation of PC-3 cells was examined by MTT assay, and the migration of PC-3 cells was detected by Transwell TM assay. Results The expression level of miR-151a-3p in the prostate cancer cells was significantly lower than that in RWPE-1 normal human prostate epithelial cells. PC-3 cells had the lowest expression level of miR-151a-3p. The bioinformatics and dual-luciferase reporter assay showed that NEK2 was the potential target gene for miR-151a-3p. After transfection with miR-151a-3p mimics, the expression of miR-151a-3p in PC-3 cells significantly increased and the expression of NEK2 mRNA significantly decreased. The protein expressions of PI3K-AKT-mTOR signaling pathway were also reduced. Up-regulation of miR-151a-3p significantly inhibited the proliferation and migration of PC-3 cells. Conclusion The expression of miR-151a-3p is reduced in prostate cancer cells. Up-regulation of miR-151a-3p can inhibit the proliferation and migration of P-3 in prostate cancer by decreasing the expression of NEK2 and PI3K

  3. MW151 Inhibited IL-1β Levels after Traumatic Brain Injury with No Effect on Microglia Physiological Responses.

    Directory of Open Access Journals (Sweden)

    Adam D Bachstetter

    Full Text Available A prevailing neuroinflammation hypothesis is that increased production of proinflammatory cytokines contributes to progressive neuropathology, secondary to the primary damage caused by a traumatic brain injury (TBI. In support of the hypothesis, post-injury interventions that inhibit the proinflammatory cytokine surge can attenuate the progressive pathology. However, other post-injury neuroinflammatory responses are key to endogenous recovery responses. Therefore, it is critical that pharmacological attenuation of detrimental or dysregulated neuroinflammatory processes avoid pan-suppression of inflammation. MW151 is a CNS-penetrant, small molecule experimental therapeutic that restores injury- or disease-induced overproduction of proinflammatory cytokines towards homeostasis without immunosuppression. Post-injury administration of MW151 in a closed head injury model of mild TBI suppressed acute cytokine up-regulation and downstream cognitive impairment. Here, we report results from a diffuse brain injury model in mice using midline fluid percussion. Low dose (0.5-5.0 mg/kg administration of MW151 suppresses interleukin-1 beta (IL-1β levels in the cortex while sparing reactive microglia and astrocyte responses. To probe molecular mechanisms, we used live cell imaging of the BV-2 microglia cell line to demonstrate that MW151 does not affect proliferation, migration, or phagocytosis of the cells. Our results provide insight into the roles of glial responses to brain injury and indicate the feasibility of using appropriate dosing for selective therapeutic modulation of injurious IL-1β increases while sparing other glial responses to injury.

    The tetraspanin Tspan8 supports via associated integrins and proteases tumor progression and angiogenesis. To shed light on its activities in non-transformed cells, we generated a Tspan8 knockout (ko) mouse, comparing leukocyte migration, angiogenesis, wound healing and tumor growth with wild type, CD151ko and Tspan8/CD151ko (dbko) mice. CD151ko mice were included as CD151 activities resemble that of Tspan8, and dbko mice to exclude mutual substitution. Tspan8ko and dbko mice show no pathological phenotype. However, delayed type hypersensitivity reactions are mitigated in Tspan8ko mice, angiogenesis is severely impaired in Tspan8ko, CD151ko and dbko mice, with Tspan8 mostly affecting lymphangiogenesis. Distinct contributions of CD151 and Tspan8 to skin wound healing rely on preferentially CD151 anchoring basal keratinocytes and Tspan8 promoting motility. Proliferation of wounded skin keratinocytes is not affected. Metastasis formation of a melanoma and a Tspan8-expressing pancreatic cancer line was impaired in Tspan8ko and dbko mice, pointing towards a contribution of host Tspan8 to tumor progression. In line with the importance of tetraspanins in exosome-mediated intercellular communication, defects became mitigated by Tspan8/CD151-competent serum exosomes, which offers a most promising therapeutic option for chronic wounds and arteriosclerosis.

    RPF151, an alkylsulfonamide capsaicin analogue, was synthesized by a simple and efficient one-step methodology. The compound was characterized by 1H and 13C NMR, elemental analysis, IR and melting point. The crystal structure of RPF151 was determined by X-ray powder diffraction and its experimental...... arrangement was compared to the lowest-energy conformer from molecular dynamics simulation. The computational and experimental findings regarding the RPF151 structural arrangement have corroborated with one another. The compound was also tested in vitro against human umbilical vein endothelial cells (HUVEC......) in order to verify its antiproliferative activity. RPF151 has significantly reduced the growth of HUVEC cells at 10 μM, suggesting that it probably would act on the angiogenesis process. RPF151 can be considered, then, as a promising anticancer lead for designing novel antitumor agents as potential drug...

    CD151, a member of the tetraspanin family of receptors, is a lateral organizer and modulator of activity of several families of transmembrane proteins. It has been implicated in the development and progression of several cancers, but its role in chronic inflammatory disease is less well understood. Here we show that CD151 is upregulated by distinct microenvironmental signals in a range of chronic inflammatory liver diseases and in primary liver cancer, in which it supports lymphocyte recruitment. CD151 was highly expressed in endothelial cells of the hepatic sinusoids and neovessels developing in fibrotic septa and tumor margins. Primary cultures of human hepatic sinusoidal endothelial cells (HSECs) expressed CD151 at the cell membrane and in intracellular vesicles. CD151 was upregulated by VEGF and HepG2 conditioned media but not by proinflammatory cytokines. Confocal microscopy confirmed that CD151 colocalized with the endothelial adhesion molecule/immunoglobulin superfamily member, VCAM-1. Functional flow-based adhesion assays with primary human lymphocytes and HSECs demonstrated a 40% reduction of lymphocyte adhesion with CD151 blockade. Inhibition of lymphocyte adhesion was similar between VCAM-1 blockade and a combination of CD151/VCAM-1 blockade, suggesting a collaborative role between the two receptors. These studies demonstrate that CD151 is upregulated within the liver during chronic inflammation, where it supports lymphocyte recruitment via liver endothelium. We propose that CD151 regulates the activity of VCAM-1 during lymphocyte recruitment to the human liver and could be a novel anti-inflammatory target in chronic liver disease and hepatocellular cancer prevention. NEW & NOTEWORTHY Chronic hepatitis is characterized by lymphocyte accumulation in liver tissue, which drives fibrosis and carcinogenesis. Here, we demonstrate for the first time that the tetraspanin CD151 supports lymphocyte adhesion to liver endothelium. We show that CD151 is upregulated

    An alpha-amylase secreted by Pichia burtonii 15-1 isolated from a traditional starter murcha of Nepal, named Pichia burtonii alpha-amylase (PBA), was studied. The gene was cloned and its nucleotide sequence was determined. PBA was deduced to consist of 494 amino acid residues. It shared certain degrees of amino acid sequence identity with other homologous proteins: 60% with Schwanniomyces occidentalis alpha-amylase, 58% with Saccharomycopsis sp. alpha-amylase, and 47% with Taka-amylase A from Aspergillus oryzae. A three-dimensional structural model of PBA generated using the known three-dimensional structure of Taka-amylase A as a template suggested high structural similarity between them. Kinetic analysis revealed that the K(m) values of PBA were lower than those of Taka-amylase A for the oligosaccharides. Although the k(cat) values of PBA were lower than those of Taka-amylase A for the oligosaccharide substrates, the k(cat)/K(m) values of PBA were higher.

    The primary objective of Experiment M151 was to study the inflight adaptation of Skylab crewmen to a variety of task situations involving different types of activity. A parallel objective was to examine astronaut inflight performance for any behavioral stress effects associated with the working and living conditions of the Skylab environment. Training data provided the basis for comparison of preflight and inflight performance. Efficiency was evaluated through the adaptation function, namely, the relation of performance time over task trials. The results indicate that the initial changeover from preflight to inflight was accompanied by a substantial increase in performance time for most work and task activities. Equally important was the finding that crewmen adjusted rapidly to the weightless environment and became proficient in developing techniques with which to optimize task performance. By the end of the second inflight trial, most of the activities were performed almost as efficiently as on the last preflight trial. The analysis demonstrated the sensitivity of the adaptation function to differences in task and hardware configurations. The function was found to be more regular and less variable inflight than preflight. Translation and control of masses were accomplished easily and efficiently through the rapid development of the arms and legs as subtle guidance and restraint systems.

    Although a number of europium water insoluble chelates have been prepared for several decades, the covalent nature of these compounds has never been established in any quantitative fashion. Shifts in the I.R. bands and conductivity measurements of these salts were hitherto used to qualitatively compare their molecular nature. In this communique we have used temperature coefficients of {sup 151}Eu Moessbauer spectra to determine the Debye temperatures ({theta}{sub D}) of three europium chelates: namely europium oxalate, europium bissalen ammonium (recently reported) and europium benzoate and compared their {theta}{sub D} with the measured {theta}{sub D} of the known ionic EuF{sub 3}. Additionally, the mean square amplitude (

    To test the ability of the Virtual Cement and Concrete Testing Laboratory (VCCTL) software to predict cement hydration properties, characterization of mineralogy and phase distribution is necessary. Compositional and textural characteristics of Cement and Concrete Reference Laboratory (CCRL) cements 151 and 152 were determined via scanning electron microscopy (SEM) analysis followed by computer modeling of hydration properties. The general procedure to evaluate a cement is as follows: (1) two-dimensional SEM backscattered electron and X-ray microanalysis images of the cement are obtained, along with a measured particle size distribution (PSD); (2) based on analysis of these images and the measured PSD, three-dimensional microstructures of various water-to-cement ratios are created and hydrated using VCCTL, and (3) the model predictions for degree of hydration under saturated conditions, heat of hydration (ASTM C186), setting time (ASTM C191), and strength development of mortar cubes (ASTM C109) are compared to experimental measurements either performed at NIST or at the participating CCRL proficiency sample evaluation laboratories. For both cements, generally good agreement is observed between the model predictions and the experimental data

    Alpha-foeto-protein, although discovered several years ago, was considered as only able to exist in primary adult liver cancer. With progress in science and in research it was observed that AFP can be found in normal subjects, without any pathological significance. APF has been found moreover in illnesses other than primary liver cancer. This range of diseases, restricted at first, has continued to widen, a development due to the discovery of new AFP detection methods and radioimmunoassay. Our work, covering 151 cases discussed in detail in the 'Material and Methods' chapter, is interesting from two viewpoints: in hepatology it is useful to know whether the very sensitive radio-immunological method reveals abnormal AFP content variations in different liver diseases; given the large number of hepatomas in our series it is also interesting to have the value of this determination confirmed in primary liver cancer diagnosis. Radioimmunoassay now replaces other quantitative methods (MANCINI's radial immunodiffusion and LAURELL's elec. diffusion) and is the most accurate [fr

    Several Schiff base complexes containing Eu 151 metal ions have been synthesized and their Moessbauer spectra are recorded using the constant acceleration velocity spectrometer. The least-square analysis method for the evaluation of the hyperfine field coupling constants is adopted using the computer dec system-10. From the systematic analysis of the quadrupole coupling constants (q.c.c.) and isomer shifts it has been established that the coordination number of the metal ion of Bis(acetylacetone) benzidine and thiourea complexes is five, that of bis-vanillin benzidine and bis-salicylaldehyde-o-dianisidine is six, and that of bis-vanillin-o-phenylene diamine is seven. It is also found that the q.c.c. being negative in all these complexes decreases monotonically as the coordination number increases. One unusual aspect of this experimental data is that most of the coordination complexes have very low f-factors whereas the Schiff base complexes studied here have a fairly high recoilless fractions. Attempts are in progress to synthesize and study the Fe Schiff base complexes in place of Eu. (auth.)

    Usher syndrome type I is an autosomal recessive disorder marked by hearing loss, vestibular areflexia, and retinitis pigmentosa. Six Usher I genetic subtypes at loci USH1A-USH1F have been reported. The MYO7A gene is responsible for USH1B, the most common subtype. In our analysis, 151 families with Usher I were screened by linkage and mutation analysis. MYO7A mutations were identified in 64 families with Usher I. Of the remaining 87 families, who were negative for MYO7A mutations, 54 were informative for linkage analysis and were screened with the remaining USH1 loci markers. Results of linkage and heterogeneity analyses showed no evidence of Usher types Ia or Ie. However, one maximum LOD score was observed lying within the USH1D region. Two lesser peak LOD scores were observed outside and between the putative regions for USH1D and USH1F, on chromosome 10. A HOMOG chi(2)((1)) plot shows evidence of heterogeneity across the USH1D, USH1F, and intervening regions. These results provide conclusive evidence that the second-most-common subtype of Usher I is due to genes on chromosome 10, and they confirm the existence of one Usher I gene in the previously defined USH1D region, as well as providing evidence for a second, and possibly a third, gene in the 10p/q region.

    While the superdeformation phenomenon has been observed many times in different mass regions, the excitation energy and angular momentum are not known for most of the superdeformed bands, mainly in the A {approx} 150 mass region. We have thus undertaken the search for and study of linking transitions between super and normal deformed potential wells in the Tb{sup 151} nucleus with the EUROBALL-IV spectrometer based at the subatomic research institute of Strasbourg. This nucleus presents the peculiarity of having an excited superdeformed band identical to the yrast one of Dy{sup 152}, which has recently been linked to normal deformed states. As the Dy{sup 152} nucleus exhibits a shape coexistence in the first potential well, we have also searched for collective rotational bands with prolate but moderate shape, coexisting with the oblate structure of Tb{sup 151}. The discovery of new superdeformed bands in the Tb{sup 151,152} isotopes, the extension to lower and higher spins of the previously known bands, and mean field calculations with a deformed Woods-Saxon potential have contributed to improve our knowledge as well as raise new questions on the orbitals configuration assignments of these bands.

    Full Text Available The quenching of the experimental spectroscopic factor for proton emission from the short-lived d3/2 isomeric state in 151mLu was a long-standing problem. In the present work, proton emission from this isomer has been reinvestigated in an experiment at the Accelerator Laboratory of the University of Jyväskylä. The proton-decay energy and half-life of this isomer were measured to be 1295(5 keV and 15.4(8 μs, respectively, in agreement with another recent study. These new experimental data can resolve the discrepancy in the spectroscopic factor calculated using the spherical WKB approximation. Using the R-matrix approach it is found that the proton formation probability indicates no significant hindrance for the proton decay of 151mLu.

    The aim of this study was to use Six Sigma(SM) (Motorola Trademark Holdings, Libertyville, IL) techniques to analyze the quality of point-of-care (POC) glucose testing measurements quantitatively and to provide suggestions for improvement. In total, 151 laboratories in China were included in this investigation in 2014. Bias and coefficient of variation were collected from an external quality assessment and an internal quality control program, respectively, for POC glucose testing organized by the National Center for Clinical Laboratories. The σ values and the Quality Goal Index were used to evaluate the performance of POC glucose meters. There were 27, 30, 57, and 37 participants in the groups using Optium Xceed™ (Abbott Diabetes Care, Alameda, CA), Accu-Chek(®) Performa (Roche, Basel, Switzerland), One Touch Ultra(®) (Abbott), and "other" meters, respectively. The median of the absolute value of percentage difference varied among different lots and different groups. Among all the groups, the Abbott One Touch Ultra group had the smallest median of absolute value of percentage difference except for lot 201411, whereas the "other" group had the largest median in all five lots. More than 85% of participate laboratories satisfied the total allowable error (TEa) requirement in International Organization for Standardization standard 15197:2013, and 85.43% (129/151) of laboratories obtained intralaboratory coefficient of variations less than 1/3TEa. However, Six Sigma techniques suggested that 41.72% (63/151) to 65.56% (99/151) of the laboratories needed to improve their POC glucose testing performance, in either precision, trueness, or both. Laboratories should pay more attention on the practice of POC glucose testing and take actions to improve their performance. Only in this way can POC glucose testing really function well in clinical practice.

    Nuclear Malaysia has successfully developed two new rice mutants namely NMR 151 and NMR 152. In addition, Nuclear Malaysia has also successfully developed Oligo chitosan and liquid bio fertilizer (Bioliquifert). Oligo chitosan acts as elicitor that has been proven to be very effective in controlling disease infections and improving yield productivity. Bioliquifert on the other hand is a mixture of microbes containing major nutrient-providing microorganisms. The objective of this study is to observe the effects of Oligo chitosan and Bioliquifert on rice mutants, NMR 151 and NMR 152. The treatment was applied on 14 day old seedlings of MR 219, NMR 151 and NMR 152 sowed in 20 cm pots containing silty clay from the paddy soil of Tanjung Karang, Selangor. The seedlings were then placed in the greenhouse at Nuclear Malaysia until it reaches 110 days old. Study was conducted in a Complete Randomized Design (CRD) with 3 replications was used and each replication consisted of three plants. All treatments received compound and single dressing fertilizer as recommended by National Rice Production Package except for Treatment 2 and 3, in which Treatment 2 received Oligo chitosan and Bioliquifert while Treatment 3 only received Bioliquifert. Results on plant height, number of tiller and plant fresh weight are not significantly different for all cultivar except for seed dry weight of NMR 152 and MR 219. (author)

    Lumbar spondylolysis (LS) has been the subject of several studies focusing on adolescent athletes. Few, if any, studies have examined LS in the general population. Lysis of the pars interarticularis of the vertebra may be associated with slipping (olisthesis), or it may be stable. In the present survey of lumbar radiographs and general epidemiological data recorded from the Copenhagen Osteoarthritis Study cohort of 4.151 subjects (age range, 22–93 years), we identified the distribution and individual risk factors for LS-development. Men were significantly more at risk of L5 spondylolysis (P = 0.002). There were no sex-specific significant differences regarding LS-incidence at the L4 level. We found no significant differences of risk of LS between nulliparous or multiparous women (L4 P = 0.54/L5 P = 0.35). Furthermore, we found no significant relationship between age at menopause and LS-development. Increased lumbar lordosis was associated to L4/L5 spondylolysis in men (L4 P spondylolysis (P spondylolysis in both men and women (P spondylolysis. The prevalence of LS increases throughout life and is apparently not a condition restricted to adolescence. Although the cross-sectional nature of the present study prevents an exact estimate of the age at onset; future, sequential studies of the cohort may provide us with some important answers on this topic. Apart from aging–obesity, lordotic angle and pelvic inclination were found to be individual risk factors for LS. PMID:17120072

    To investigate the safety, response rate, progression-free and overall survival of patients with liver metastases treated with (90)Y (glass) radioembolisation in a prospective, multicenter phase II study. 151 patients with liver metastases (colorectal n=61, neuroendocrine n=43 and other tumour types n=47) refractory to standard of care therapies were enrolled in this prospective, multicenter, phase II study under an investigational device exemption. Clinical/laboratory/imaging follow-up were obtained at 30 days followed by 3-month intervals for 1 year and every 6 months thereafter. The primary end-point was progression-free survival (PFS); secondary end-points included safety, hepatic progression-free survival (HPFS), response rate and overall survival. Median age was 66 (range 25-88). Grade 3/4 adverse events included pain (12.8%), elevated alkaline phospatase (8.1%), hyperbilirubinemia (5.3%), lymphopaenia (4.1%), ascites (3.4%) and vomiting (3.4%). Treatment parameters including dose delivery were reproducible among centers. Disease control rates were 59%, 93% and 63% for colorectal, neuroendocrine and other primaries, respectively. Median PFS was 2.9 and 2.8 months for colorectal and other primaries, respectively. PFS was not achieved in the neuroendocrine group. Median survival from (90)Y treatment was 8.8 months for colorectal and 10.4 months for other primaries. Median survival for neuroendocrine patients has not been reached. Patients with liver metastases can be safely treated with (90)Y microspheres. This study is the first to demonstrate technical and dose reproducibility of (90)Y glass microspheres between centers in a prospective setting. Based on these promising data, three international, multicenter, randomised phase III studies in colorectal and hepatocellular carcinoma have been initiated. Copyright © 2013 Elsevier Ltd.

    Rotational bands, characteristic of a superdeformed prolate shape (epsilon approx. = 0.6) and extending to above spin 60 Planck constant, have been observed in both /sup 150/Gd and /sup 151/Tb. The magnitudes of the moments of inertia I/sup (2)/ were found to vary with frequency and the variation greatly exceeded that seen in /sup 148,149/Gd and /sup 151,152/Dy. The differences in the I/sup (2)/'s are attributed to the occupation of particular high-N orbitals. Moreover, contrary to the previous examples the bands in both /sup 150/Gd and /sup 151/Tb de-excited at a much higher rotational frequency of Planck constant..omega.. approx. = 0.4 MeV and this may indicate that the pair gap extends to higher frequencies in /sup 150/Gd and /sup 151/Tb.

    Full Text Available HIV-1 carrying the "Q151M complex" reverse transcriptase (RT mutations (A62V/V75I/F77L/F116Y/Q151M, or Q151Mc is resistant to many FDA-approved nucleoside RT inhibitors (NRTIs, but has been considered susceptible to tenofovir disoproxil fumarate (TFV-DF or TDF. We have isolated from a TFV-DF-treated HIV patient a Q151Mc-containing clinical isolate with high phenotypic resistance to TFV-DF. Analysis of the genotypic and phenotypic testing over the course of this patient's therapy lead us to hypothesize that TFV-DF resistance emerged upon appearance of the previously unreported K70Q mutation in the Q151Mc background. Virological analysis showed that HIV with only K70Q was not significantly resistant to TFV-DF. However, addition of K70Q to the Q151Mc background significantly enhanced resistance to several approved NRTIs, and also resulted in high-level (10-fold resistance to TFV-DF. Biochemical experiments established that the increased resistance to tenofovir is not the result of enhanced excision, as K70Q/Q151Mc RT exhibited diminished, rather than enhanced ATP-based primer unblocking activity. Pre-steady state kinetic analysis of the recombinant enzymes demonstrated that addition of the K70Q mutation selectively decreases the binding of tenofovir-diphosphate (TFV-DP, resulting in reduced incorporation of TFV into the nascent DNA chain. Molecular dynamics simulations suggest that changes in the hydrogen bonding pattern in the polymerase active site of K70Q/Q151Mc RT may contribute to the observed changes in binding and incorporation of TFV-DP. The novel pattern of TFV-resistance may help adjust therapeutic strategies for NRTI-experienced patients with multi-drug resistant (MDR mutations.

    Full Text Available A response to Van der Watt’s article on ‘Intertextuality and over-interpretation: References to Genesis 28:12 in John 1:51?’ This article is a response to an article of Van der Watt titled ‘Intertextuality and over-interpretation: References to Genesis 28:12 in John 1:51?’ (2016. He states in this article that his aim is ‘to illustrate the dangers of over-interpretation when dealing with intertextual relations between texts, especially when allusion is assumed’. He then gives a brief survey of different interpretations of John 1:51. Van der Watt shows in his article how theologians use themes from Genesis 28:12 (like the ladder, Jacob or Bethel, which are not mentioned in John 1:51 in their expositions of John 1:51. Van der Watt regards some of these expositions as examples of over-interpretation. The aim of my article is to show how Church Fathers interpreted Genesis 28:12 and John 1:51. I show in my article that the Church Fathers saw several parallels between these two sections from the Bible. Furthermore, I suggest that the early theologians’ interpretations formed a tradition that probably influenced modern interpreters of the Bible. I also discuss the role of typology in the history of interpretation, specifically also in the case of Genesis 28:12 and John 1:51. I then argue that it is perhaps not so far-fetched to see an intertextual relation between Genesis 28:12 and John 1:51.

    New research has suggested the clinical use of lysergic acid diethylamide (LSD) and psilocybin in selected patient populations. However, concerns about the clinical use of LSD were advanced in a large Danish follow-up study that assessed 151 LSD-treated psychiatric patients approximately 25 years after their treatment in the 1960s. The purpose of the present study was to give a retrospective account of the short-term outcome of LSD treatment in these 151 Danish psychiatric patients. The LSD case material in the Danish State Archives consists of medical case records of 151 LSD-treated patients, who complained and received economic compensation with the LSD Damages Law. The author carefully read and reviewed the LSD case material. LSD was used to treat a wide spectrum of mental disorders. Independent of diagnoses, 52 patients improved, and 48 patients worsened acutely with the LSD treatment. In a subgroup of 82 neurotic patients, the LSD dose-index (number of treatments multiplied by the maximal LSD dose) indicated the risk of acute worsening. In another subgroup of 19 patients with obsessive-compulsive neurosis, five patients later underwent psychosurgery. A small subgroup of 12 patients was treated with psilocybin. The long-term outcome was poor in most of the patients. Despite the significant limitations to a retrospective design, this database warrants caution in mental health patients. The use of LSD and psilocybin in mental health patients may be associated with serious short- and long-term side effects. Until further trials with rigorous designs have cleared these drugs of their potential harms, their clinical utility in these groups of patients has not been fully clarified.

    Total neutron cross-section measurements have been carried out for natural Eu and its stable isotopes in the energy range from 3 meV-1 eV. The measurements were performed using two time-of-flight spectrometers installed in front of two of the horizontal channels of the ET-RR-1 reactor. The following results have been obtained: sigmasub(α)( 151 Eu) = 9180+-150 b at 0.0253 eV; sigmasub(α)( 153 Eu) = 375+-20 b at 0.0253 eV; sigmasub(α)(Eu) = 4600+-120 b at 0.0253 eV

    The measurement of **1**5**1Sm(n, gamma)**1**5**2Sm (samarium) cross section showed improved performance of the new spallation neutron facility. It covered a wide energy range with good resolution, high neutron flux, low backgrounds and a favourable duty factor. The samarium cross section was found to be of great importance for characterizing neutron capture nucleosynthesis in asymptotic giant stars. The combination of these features provided a promising basis for a broad experimental program directed towards application in astrophysics and advanced nuclear technologies. (Edited abstract)

    The methodology proposed by the National Council on Radiation Protection 151 (NCRP 151), relates technical information necessary to structural shielding design and evaluation for megavoltage X- and gamma- ray radiotherapy facilities. However, many parameters used to calculate the shield are based on estimates, and may not be adequate to the Brazilian reality. Thus, the central idea of this study is to obtain parameters and is to outline a profile closer to the treatments carried out in facilities in Brazil, through a data collection routine of the Department of Radiotherapy Service of the Real e Benemerita Associacao Portuguesa de Beneficencia, in particular the cobalt therapy Theratron 780 (Atomic Energy of Canada Ltd.) and the linear accelerator Varian Clinac 2100C for measurement of workload, use factor, number of patients, fields, dose and anatomic region treated. So, the work did not draw definite values of the parameters, but indicative values were obtained which showed the importance to carry out more detailed studies of the recommended values. (author)

    This report provides the qualification status of experimental data for the entire Advanced Gas Reactor 3/4 (AGR 3/4) fuel irradiation. AGR-3/4 is the third in a series of planned irradiation experiments conducted in the Advanced Test Reactor (ATR) at Idaho National Laboratory (INL) for the AGR Fuel Development and Qualification Program, which supports development of the advanced reactor technology under the INL ART Technology Development Office (TDO). The main objective of AGR-3/4 irradiation is to provide a known source of fission products for subsequent transport through compact matrix and structural graphite materials due to the presence of designed-to-fail fuel particles. Full power irradiation of the AGR 3/4 test began on December 14, 2011 (ATR Cycle 151A), and was completed on April 12, 2014 (end of ATR Cycle 155B) after 369.1 effective full power days of irradiation. The AGR-3/4 test was in the reactor core for eight of the ten ATR cycles between 151A and 155B. During the unplanned outage cycle, 153A, the experiment was removed from the ATR northeast flux trap (NEFT) location and stored in the ATR canal. This was to prevent overheating of fuel compacts due to higher than normal ATR power during the subsequent Powered Axial Locator Mechanism cycle, 153B. The AGR 3/4 test was inserted back into the ATR NEFT location during the outage of ATR Cycle 154A on April 26, 2013. Therefore, the AGR-3/4 irradiation data received during these 2 cycles (153A and 153B) are irrelevant and their qualification status isnot included in this report. Additionally, during ATR Cycle 152A the ATR core ran at low power for a short enough duration that the irradiation data are not used for physics and thermal calculations. However, the qualification status of irradiation data for this cycle is still covered in this report. As a result, this report includes data from 8 ATR Cycles: 151A, 151B, 152A, 152B, 154A, 154B, 155A, and 155B, as recorded in the Nuclear Data Management and

    In recent years, the progress experienced in cancer treatment with ionizing radiation can deliver higher doses to smaller volumes and better shaped, making it necessary to take into account new aspects in the calculation of structural barriers. Furthermore, given that forecasts suggest that in the near future will install a large number of accelerators, or existing ones modified, we believe a useful tool to estimate the thickness of the structural barriers of treatment rooms. The shielding calculation methods are based on standard DIN 6847-2 and the recommendations given by the NCRP 151. In our experience we found only estimates originated from the DIN. Therefore, we considered interesting to develop an application that incorporates the formulation suggested by the NCRP, together with previous work based on the rules DIN allow us to establish a comparison between the results of both methods.

    The heat capacity (C p ) and dilatation (α) of YB 12 and LuB 12 are studied. C p of the zone-melted YB 12 tricrystal is measured in the range 2.5-70 K, of the zone-melted LuB 12 single crystal in the range 0.6-70 K, and of the LuB 12 powder sample in the range 4.3-300 K; α of the zone-melted YB 12 tricrystal and LuB 12 single crystals is measured in the range 5-200 K. At low temperatures a negative thermal expansion (NTE) is revealed for both compounds: for YB 12 at 50-70 K, for LuB 12 at 10-20 K and 60-130 K. Their high-temperature NTE is a consequence of nearly non-interacting freely oscillating metal ions (Einstein oscillators) in cavities of a simple cubic rigid Debye lattice formed by B 12 cage units. The Einstein temperatures are ∼254 and ∼164 K, and the Debye temperatures are ∼1040 K and ∼1190 K for YB 12 and LuB 12 respectively. The LuB 12 low-temperature NTE is connected with an induced low-energy defect mode. The YB 12 superconducting transition has not been detected up to 2.5 K

    Experiences with the new palliative agent Lu-177 EDTMP are summarized. The production of primary 177 Lu by the 176 Lu(n,γ) 177 Lu reaction and the synthesis of the radioactive complex are described as well as the procedures used for the control of the radionuclidic and the radiochemical purity. The stability of the compound has been also studied. The in vivo essays with rats and the use of the radiopharmaceutical, after a careful dose evaluation, in a patient with bone metastases from a breast cancer, show that the behaviour of Lu-177 EDTMP is similar to that of the analogue Sm-153 EDTMP.

    Xanthomonas axonopodis pv. manihotis (Xam) is the causal agent of bacterial blight of cassava, which is among the main components of human diet in Africa and South America. Current information about the molecular pathogenicity factors involved in the infection process of this organism is limited. Previous studies in other bacteria in this genus suggest that advanced draft genome sequences are valuable resources for molecular studies on their interaction with plants and could provide valuable tools for diagnostics and detection. Here we have generated the first manually annotated high-quality draft genome sequence of Xam strain CIO151. Its genomic structure is similar to that of other xanthomonads, especially Xanthomonas euvesicatoria and Xanthomonas citri pv. citri species. Several putative pathogenicity factors were identified, including type III effectors, cell wall-degrading enzymes and clusters encoding protein secretion systems. Specific characteristics in this genome include changes in the xanthomonadin cluster that could explain the lack of typical yellow color in all strains of this pathovar and the presence of 50 regions in the genome with atypical nucleotide composition. The genome sequence was used to predict and evaluate 22 variable number of tandem repeat (VNTR) loci that were subsequently demonstrated as polymorphic in representative Xam strains. Our results demonstrate that Xanthomonas axonopodis pv. manihotis strain CIO151 possesses ten clusters of pathogenicity factors conserved within the genus Xanthomonas. We report 126 genes that are potentially unique to Xam, as well as potential horizontal transfer events in the history of the genome. The relation of these regions with virulence and pathogenicity could explain several aspects of the biology of this pathogen, including its ability to colonize both vascular and non-vascular tissues of cassava plants. A set of 16 robust, polymorphic VNTR loci will be useful to develop a multi-locus VNTR analysis

    We present velocity-delay maps for optical H I, He I, and He II recombination lines in Arp 151, recovered by fitting a reverberation model to spectrophotometric monitoring data using the maximum-entropy method. H I response is detected over the range 0-15 days, with the response confined within the virial envelope. The Balmer-line maps have similar morphologies but exhibit radial stratification, with progressively longer delays for Hγ to Hβ to Hα. The He I and He II response is confined within 1-2 days. There is a deficit of prompt response in the Balmer-line cores but strong prompt response in the red wings. Comparison with simple models identifies two classes that reproduce these features: free-falling gas and a half-illuminated disk with a hot spot at small radius on the receding lune. Symmetrically illuminated models with gas orbiting in an inclined disk or an isotropic distribution of randomly inclined circular orbits can reproduce the virial structure but not the observed asymmetry. Radial outflows are also largely ruled out by the observed asymmetry. A warped-disk geometry provides a physically plausible mechanism for the asymmetric illumination and hot spot features. Simple estimates show that a disk in the broad-line region of Arp 151 could be unstable to warping induced by radiation pressure. Our results demonstrate the potential power of detailed modeling combined with monitoring campaigns at higher cadence to characterize the gas kinematics and physical processes that give rise to the broad emission lines in active galactic nuclei.

  3. Cul3-mediated Nrf2 ubiquitination and antioxidant response element (ARE) activation are dependent on the partial molar volume at position 151 of Keap1.

    2009-07-29

    Nrf2 (nuclear factor erythroid 2-related factor 2) is a transcription factor that activates transcription of a battery of cytoprotective genes by binding to the ARE (antioxidant response element). Nrf2 is repressed by the cysteine-rich Keap1 (kelch-like ECH-associated protein 1) protein, which targets Nrf2 for ubiquitination and subsequent degradation by a Cul3 (cullin 3)-mediated ubiquitination complex. We find that modification of Cys(151) of human Keap1, by mutation to a tryptophan, relieves the repression by Keap1 and allows activation of the ARE by Nrf2. The Keap1 C151W substitution has a decreased affinity for Cul3, and can no longer serve to target Nrf2 for ubiquitination, though it retains its affinity for Nrf2. A series of 12 mutant Keap1 proteins, each containing a different residue at position 151, was constructed to explore the chemistry required for this effect. The series reveals that the extent to which Keap1 loses the ability to target Nrf2 for degradation, and hence the ability to repress ARE activation, correlates well with the partial molar volume of the residue. Other physico-chemical properties do not appear to contribute significantly to the effect. Based on this finding, a structural model is proposed whereby large residues at position 151 cause steric clashes that lead to alteration of the Keap1-Cul3 interaction. This model has significant implications for how electrophiles which modify Cys(151), disrupt the repressive function of Keap1.

  4. Correlations between transmembrane 4 L6 family member 5 (TM4SF5, CD151, and CD63 in liver fibrotic phenotypes and hepatic migration and invasive capacities.

    Directory of Open Access Journals (Sweden)

    Full Text Available Transmembrane 4 L6 family member 5 (TM4SF5 is overexpressed during CCl4-mediated murine liver fibrosis and in human hepatocellular carcinomas. The tetraspanins form tetraspanin-enriched microdomains (TEMs consisting of large membrane protein complexes on the cell surface. Thus, TM4SF5 may be involved in the signal coordination that controls liver malignancy. We investigated the relationship between TM4SF5-positive TEMs with liver fibrosis and tumorigenesis, using normal Chang hepatocytes that lack TM4SF5 expression and chronically TGFβ1-treated Chang cells that express TM4SF5. TM4SF5 expression is positively correlated with tumorigenic CD151 expression, but is negatively correlated with tumor-suppressive CD63 expression in mouse fibrotic and human hepatic carcinoma tissues, indicating cooperative roles of the tetraspanins in liver malignancies. Although CD151 did not control the expression of TM4SF5, TM4SF5 appeared to control the expression levels of CD151 and CD63. TM4SF5 interacted with CD151, and caused the internalization of CD63 from the cell surface into late lysosomal membranes, presumably leading to terminating the tumor-suppressive functions of CD63. TM4SF5 could overcome the tumorigenic effects of CD151, especially cell migration and extracellular matrix (ECM-degradation. Taken together, TM4SF5 appears to play a role in liver malignancy by controlling the levels of tetraspanins on the cell surface, and could provide a promising therapeutic target for the treatment of liver malignancies.

    The subject of this thesis is the study of superdeformation (SD) of the atomic nucleus. In the mass region A {approx_equal} 150 those nuclei have a quadrupole deformation of about 0.6. However, this value is an average and the microscopic structure reflected in the band configurations, affects this deformation. Determination of this value by electric quadrupole moment studies is particularly useful especially for the identical SD bands (SD bands belonging to neighbouring nuclei and having the same moment of inertia). Knowledge of the different quadrupole deformation should shed light on the competition between mass difference, spin alignment and deformation of the nucleus. The electric quadrupole moments are deduced from lifetime measurements of the SD states using the Doppler Shift Attenuation Method. Experimentally, one observes a variation in the electric quadrupole moments of the lowest SD states which suggests a gradual change of the nuclear deformation towards normal less deformed shapes. The deexcitation mechanism is poorly understood in the A {approx_equal} 150 mass region due to lack of experimental information: up to now, no transition connecting the second and the first potential well has been observed for these SD states. Experimental studies of deexcitation patterns of SD bands are therefore crucial to fix the decay-out mechanism. Experimental data on the {sup 151}Tb nucleus were collected via fusion-evaporation reaction, using the EUROGAM phase II array. (author) 121 refs., 61 figs., 22 tabs.

    To determine prognostic factors for and compare outcome among dogs with oral malignant melanoma following excision with or without various systemic adjuvant therapies. Retrospective case series. 151 dogs with naturally occurring oral malignant melanomas treated by excision with or without adjuvant therapies from 2001 to 2012. Case accrual was solicited from Veterinary Society of Surgical Oncology members via an email list service. Information collected from case records included signalment, tumor staging, tumor characteristics, type of surgical excision, histologic diagnosis, adjuvant therapy, and survival time. The overall median survival time was 346 days. Results of multivariate analysis indicated that tumor size, patient age, and intralesional excision (vs marginal, wide, or radical excision) were considered poor prognostic indicators. All other demographic and clinical variables were not significantly associated with survival time after adjusting for the aforementioned 3 variables. A clear survival benefit was not evident with any systemic adjuvant therapy, including vaccination against melanoma or chemotherapy; however, the number of dogs in each treatment group was small. Ninety-eight dogs received no postoperative adjuvant therapy, and there was no difference in survival time between dogs that did (335 days) and did not (352 days) receive systemic adjuvant therapy. For dogs with oral malignant melanoma, increasing tumor size and age were negative prognostic factors. Complete excision of all macroscopic tumor burden improved survival time. Long-term survival was possible following surgery alone. Although systemic adjuvant therapy was not found to improve survival time, this could have been due to type II error.

    The subject of this thesis is the study of superdeformation (SD) of the atomic nucleus. In the mass region A ≅ 150 those nuclei have a quadrupole deformation of about 0.6. However, this value is an average and the microscopic structure reflected in the band configurations, affects this deformation. Determination of this value by electric quadrupole moment studies is particularly useful especially for the identical SD bands (SD bands belonging to neighbouring nuclei and having the same moment of inertia). Knowledge of the different quadrupole deformation should shed light on the competition between mass difference, spin alignment and deformation of the nucleus. The electric quadrupole moments are deduced from lifetime measurements of the SD states using the Doppler Shift Attenuation Method. Experimentally, one observes a variation in the electric quadrupole moments of the lowest SD states which suggests a gradual change of the nuclear deformation towards normal less deformed shapes. The deexcitation mechanism is poorly understood in the A ≅ 150 mass region due to lack of experimental information: up to now, no transition connecting the second and the first potential well has been observed for these SD states. Experimental studies of deexcitation patterns of SD bands are therefore crucial to fix the decay-out mechanism. Experimental data on the 151 Tb nucleus were collected via fusion-evaporation reaction, using the EUROGAM phase II array. (author)

    Kildea, John

    This thesis describes a study of shielding design techniques used for radiation therapy facilities that employ megavoltage linear accelerators. Specifically, an evaluation of the shielding design formalism described in NCRP report 151 was undertaken and a feasibility study for open-door 6 MV radiation therapy treatments in existing 6 MV, 18 MV treatment rooms at the Montreal General Hospital (MGH) was conducted. To evaluate the shielding design formalism of NCRP 151, barrier-attenuated equivalent doses were measured for several of the treatment rooms at the MGH and compared with expectations from NCRP 151 calculations. It was found that, while the insight and recommendations of NCRP 151 are very valuable, its dose predictions are not always correct. As such, the NCRP 151 methodology is best used in conjunction with physical measurements. The feasibility study for 6 MV open-door treatments made use of the NCRP 151 formalism, together with physical measurements for realistic 6 MV workloads. The results suggest that, dosimetrically, 6 MV open door treatments are feasible. A conservative estimate for the increased dose at the door arising from such treatments is 0.1 mSv, with a 1/8 occupancy factor, as recommended in NCRP 151, included.

    Studies on arthroscopic removal of apical proximal sesamoid fracture fragments in Thoroughbred (TB) horses age > or = 2 years have reported a high success rate. However, there are no reports documenting the racing prognosis of TB horses that undergo such surgery as weanlings or yearlings. To describe the incidence of apical proximal sesamoid fractures in immature TB horses, age fractures in 151 TB weanlings and yearlings. The medical records of TB horses age fracture fragments were reviewed. Follow-up information was obtained from race records. Student's t tests were used to compare performance variables of operated racehorses to that of their maternal siblings. Ninety-two percent (139/151) of fractures occurred in the hindlimbs and 8% (11/151) in the forelimbs (fracture of both fore- and hindlimb, n = 1). Horses with forelimb fractures had a greatly reduced probability of racing (55%) compared to those with hindlimb fractures (86%). Overall, 84% of the horses raced post operatively and had performance records similar to that of their maternal siblings, 78% (787/1006) of which raced. Arthroscopic removal of apical proximal sesamoid fracture fragments in TB weanlings and yearlings carries an excellent prognosis for racing in horses with hindlimb fractures and a reduced prognosis in those with forelimb fractures. Medial fractures of the forelimb carry the worst prognosis. The determination of prognosis increases knowledge on apical sesamoid bone fractures and potential for arthroscopic restoration of the ability to race; and enables the value of yearlings for subsequent sale to be established.

    The transcription factor NF-kappaB (NF-kB) is a key regulator of cytokine and chemokine production in melanoma and is responsible for symptoms such as anorexia, fatigue, and weight loss. In addition, NF-kB is believed to contribute to progression of the disease by upregulation of cell cycle and anti-apoptotic genes and to contribute to resistance against targeted therapies and immunotherapy. In this study, we have examined the ability of the bromodomain and extra-terminal (BET) protein inhibitor I-BET151 to inhibit NF-kB in melanoma cells. We show that I-BET151 is a potent, selective inhibitor of a number of NF-kB target genes involved in induction of inflammation and cell cycle regulation and downregulates production of cytokines such as IL-6 and IL-8. SiRNA studies indicate that BRD2 is the main BET protein involved in regulation of NF-kB and that I-BET151 caused transcriptional downregulation of the NF-kB subunit p105/p50. These results suggest that BET inhibitors may have an important role in treatment of melanoma where activation of NF-kB may have a key pathogenic role. © 2014 John Wiley & Sons A/S.

    Consumer interest in health-promoting food products is a major driving force for the increasing global demand of functional (probiotic) dairy foods. Yogurt is considered the ideal medium for delivery of beneficial functional ingredients. Gamma-amino-butyric acid has potential as a bioactive ingredient in functional foods due to its health-promoting properties as an anti-stress, anti-hypertensive, and anti-diabetic agent. Here, we report the use of a novel Streptococcus thermophilus strain, isolated from the digestive tract of fish, for production of yogurt naturally enriched with 2 mg/ml of gamma-amino-butyric acid (200 mg in a standard yogurt volume of 100 ml), a dose in the same range as that provided by some commercially available gamma-amino-butyric acid supplements. The biotechnological suitability of this strain for industrial production of yogurt was demonstrated by comparison with the reference yogurt inoculated with the commercial CH1 starter (Chr. Hansen) widely used in the dairy industry. Both yogurts showed comparable pH curves [ΔpH/Δ t = 0.31-0.33 h -1 ], viscosity [0.49 Pa-s], water holding capacity [72-73%], and chemical composition [moisture (87-88%), protein (5.05-5.65%), fat (0.12-0.15%), sugar (4.8-5.8%), and ash (0.74-1.2%)]. Gamma-amino-butyric acid was not detected in the control yogurt. In conclusion, the S. thermophilus APC151 strain reported here provides a natural means for fortification of yogurt with gamma-amino-butyric acid.

    Tularemia is a serious and potentially life-threatening zoonosis caused by Francisella tularensis, a highly infective, gram-negative coccobacillus. Although there are plenty of case reports and studies of tularemia outbreaks, the literature is lacking in reports on dermatologic manifestations of the disease. This study aimed to identify skin manifestations in clinical forms of tularemia. A total of 151 patients diagnosed with tularemia at Çankırı State Hospital, Çankırı, Turkey, were retrospectively examined. Dermatologic data for these patients were assessed. The most frequent clinical manifestation of tularemia was the glandular form (49.7%), followed by the oropharyngeal, ulceroglandular, and oculoglandular forms (39.1, 6.0, and 5.3%, respectively). Physical manifestations were observed in 64.5% of females and 56.9% of males. Lymphadenopathy and tonsillitis were the most frequent physical findings and were noted in 57.6 and 25.2% of patients, respectively. Erythema multiforme was found in 17 patients (11.3%), most of whom presented with the oropharyngeal and glandular forms, and was followed by ulcer (6.0%), urticaria (3.3%), erythema nodosum (2.6%), and cellulitis (0.7%). However, it should be noted that this study was retrospective and that its patient sample demonstrated four of the six clinical forms of tularemia. Patients with the oropharyngeal form of tularemia had statistically significantly more physical findings than those with other clinical forms of the disease (P < 0.001). There were statistically more skin findings in the ulceroglandular form (P < 0.001). There was no statistical correlation between serum antibody titers and cutaneous findings (P = 0.585). Although the literature reports that skin lesions are observed more frequently in women than in men, we did not find any statistically significant difference between the sexes in any type of skin lesion. © 2014 The International Society of Dermatology.

    The aims of the present study were threefold: to examine the distribution of knee joint osteoarthritis in a large, standardized radiological study; to examine the relationships between self reported knee pain and radiological OA; and to examine the natural history of radio-morphological change over age in individuals without radiological features of OA. The Copenhagen Osteoarthritis Study - COS is a substudy of the Copenhagen City Heart Study, a longitudinal regional health survey. From the third inclusion of the CCHS (1992-1994) 4,151 subjects were selected for subsequent standardized radiography of the pelvis, the knees, the hands, the wrists, and the lumbar spine. Images were analyzed and knee joint osteoarthritis (OA) was classified according to the radiographic atlas of Kellgren and Lawrence. Joint space width (JSW) was measured at three sites within both the medial and the lateral compartment. For the entire cohort the prevalence of radiological knee joint OA of all grades was 38.7% for men and 44.2% for women. Age stratification documented increasing knee joint OA both in regard to prevalence and morphological severity. Knee pain was universally correlated to the Kellgren and Lawrence severity of OA. In a subgroup with no features of radiological OA, a significant and linear decline in JSW with increasing age was found. We found a clear relationship between self-reported knee pain and radiological osteoarthritis. Pain was proportionally related to the severity of change. We also demonstrated a significant diminishing of joint space width with increasing age in individuals without apparent radiological degeneration. (orig.)

    Full Text Available Two strains (15.1 and 15.8 of the thermophilic fungus Scytalidium thermophilum produced high levels of intracellular glucoamylases, with potential for industrial applications. The isoform I of the glucoamylase produced by 15.1 strain was sequentially submitted to DEAE-Cellulose and CM-Cellulose chromatography, and purified 141-fold, with 5.45% recovery. The glucoamylase of strain 15.8 was purified 71-fold by CM-Cellulose and Concanavalin A-Sepharose chromatography, with 7.38% recovery. Temperature and pH optima were in the range of 50-60ºC and 5.0-6.0, respectively, using starch and maltose as substrates. The glucoamylase of S. thermophilum 15.8 was more stable (t50 > 60 min than that of S. thermophilum 15.1 (t50= 11-15 min, at 60ºC. The glucoamylase activities were enhanced by several ions (e.g. Mn2+ and Ca2+ and inhibited by β-mercaptoethanol. The glucoamylase from 15.1 strain showed a Km of 0.094 mg/ml and 0.029 mg/ml and Vmax of 202 U/mg prot and 109 U/mg prot, for starch and maltose, respectively. The hydrolysis products of starch and maltose, analyzed by TLC, demonstrated glucose as end product and confirming the character of the enzyme as glucoamylase. Differences were observed in relation to the products formed with maltose as substrate between the two strains studied. S. thermophilum 15.8 formed maltotriose in contrast with S. thermophilum 15.1.Duas linhagens (15.1 e 15.8 do fungo termofílico Scytalidium thermophilum se mostraram produtoras de grandes quantidades de glucoamilases, com potencial aplicação industrial.

    The behavior of lanthanum (III), praseodymium (III), and lutetium (III) was studied in 2 M NaClO{sub 4} (aq) and 2 M NaCl (aq) at 303 K and free -CO{sub 2} conditions. Solubility diagrams (p Ln(aq)-pC{sub H}) were obtained by means of a radiochemical method. The pC{sub H} borderlines of saturation and unsaturation zones of the solutions and solubility product constants for Ln(OH){sub 3} were determined from these diagrams. The fitting of the solubility equation to the experimental values of p Ln(aq)-pC{sub H} diagrams allowed the calculation of the first hydrolysis and solubility product constants. Independently, the stability constants for the first species of hydrolysis were determined by means of pH titrations, the data were treated with the program SUPERQUAD and fitted to the mean ligand number equation. The stability constants for the species LnCl{sup 2+} were as well calculated in 2M ionic strength and 303 K from the hydrolysis constant values obtained in both perchlorate and chloride media. The values obtained for La, Pr and Lu were: logK{sub ps}: 21.11 {+-} 0.09, 19.81 {+-} 0.11 and 18.10 {+-} 0.13 in 2M NaClO{sub 4}; logK{sub ps}: 22.22 {+-} 0.09, 21.45 {+-} 0.14 and 18.52 {+-} 0.29 in 2M NaCl; log {beta}{sub 1}: - 8.64 {+-} 0.02, - 8.37 {+-} 0.01 and - 7.95 {+-} 0.11 in 2M NaClO{sub 4}; log {beta}{sub 1}{sup /} : - 9.02 {+-} 0.11, - 8.75 {+-} 0.01 and - 8.12 {+-} 0.03 in 2M NaCl and the values for log {beta}{sub 1,Cl} were - 0.0255, - 0.155 and - 0.758, respectively.

    The structure of the HIV-1 reverse transcriptase Q151M mutant was determined at a resolution of 2.6 Å in space group P321. Hepatitis B virus polymerase (HBV Pol) is an important target for anti-HBV drug development; however, its low solubility and stability in vitro has hindered detailed structural studies. Certain nucleotide reverse transcriptase (RT) inhibitors (NRTIs) such as tenofovir and lamivudine can inhibit both HBV Pol and Human immunodeficiency virus 1 (HIV-1) RT, leading to speculation on structural and mechanistic analogies between the deoxynucleotide triphosphate (dNTP)-binding sites of these enzymes. The Q151M mutation in HIV-1 RT, located at the dNTP-binding site, confers resistance to various NRTIs, while maintaining sensitivity to tenofovir and lamivudine. The residue corresponding to Gln151 is strictly conserved as a methionine in HBV Pol. Therefore, the structure of the dNTP-binding pocket of the HIV-1 RT Q151M mutant may reflect that of HBV Pol. Here, the crystal structure of HIV-1 RT Q151M, determined at 2.6 Å resolution, in a new crystal form with space group P321 is presented. Although the structure of HIV-1 RT Q151M superimposes well onto that of HIV-1 RT in a closed conformation, a slight movement of the β-strands (β2–β3) that partially create the dNTP-binding pocket was observed. This movement might be caused by the introduction of the bulky thioether group of Met151. The structure also highlighted the possibility that the hydrogen-bonding network among amino acids and NRTIs is rearranged by the Q151M mutation, leading to a difference in the affinity of NRTIs for HIV-1 RT and HBV Pol

    Anaerobic fermentation using Clostidium butyricum NCIB 9576, and phto-fermentation using Rhodopseudomonas sphaeroides E15-1 were studied for the production of hydrogen from Makkoli, fruits (orange and apple, watermelon and melon) and Tofu wastewaters. From the Makkoli wastewater, which contained 0.94 g/liter sugars and 2.74 g/liter solubel starch, approximately 49 mM H{sub 2}/liter wastewater was produced during the initial 18h of the anaerobic fermentation with pH control between 6.5-7.0. Several organic acids such as butyric acid, acetic acid, propionic acid, lactic acid and ethanol were also produced. From watermelon and melon wastewater, which contained 43 g/liter sugars, generated about approximately 71 mM H{sub 2}/liter wastewater was produced during the initial 24h of the anaerobic fermentation. Tofu wastewater, pH 6.5, containing 12.6 g/liter soluble starch and 0.74 g/liter sugars, generated about 30mM H{sub 2}/liter wastewater, along with some organic acids, during the initial 24 h of anaerobic fermentation. Makkoli and Tofu wastewaters as substrates for the photo-fermentation by Rhodopseudomonas sphaeroides E15-1 produced approximately 37.9 and 22.2 {mu}M H{sub 2}/ml wastewaters, respectively for 9 days of incubation under the average of 9,000010,000 lux illumination at the surface of reactor using tungsten halogen lamps. Orange and apple wastewater, which contained 93.4 g/l produced approximately 13.1 {mu}M H{sub 2}/ml wastewater only for 2 days of photo-fermentation and the growth of Rhodopseudomonas spnaeroides E15-1 and hydrogen production were stopped. 22 refs, 4 figs., 2 tabs.

After some introductory per-spectives on the monotheism debate in general a few themes are identified from Exodus 15. These include themes such as of the incomparability of Yahweh, His kingship as well as the exclusivity of Yahweh’s existence and the theme of worshipping him. Finally, the praise of Yahweh as God of the gods forms the climax for this theological construct. The concept is then proposed as basis for the monolatric-monotheistic discussion in the psalms.

    Purpose We investigated the effect of triple monoclonal antibody inhibition of EGFR to overcome acquired resistance to first generation of anti-EGFR inhibitors. Experimental design MM151 is a mixture of three different monoclonal IgG1 antibodies directed toward three different, non-overlapping, epitopes of the EGFR. We performed an in vivo study by using human CRC cell lines (SW48, LIM 1215 and CACO2) which are sensitive to EGFR inhibitors, in order to evaluate the activity of MM151 as compared to standard anti-EGFR mAbs, such as cetuximab, as single agent or in a sequential strategy of combination MM151 with irinotecan (induction therapy) followed by MM151 with a selective MEK1/2 inhibitor (MEKi) (maintenance therapy). Furthermore, the ability of MM151 to overcome acquired resistance to cetuximab has been also evaluated in cetuximab-refractory CRC models. Results MM151 shown stronger antitumor activity as compared to cetuximab. The maintenance treatment with MM151 plus MEKi resulted the most effective therapeutic modality. In fact, this combination caused an almost complete suppression of tumor growth in SW48, LIM 1215 and CACO2 xenografts model at 30 week. Moreover, in this treatment group, mice with no evidence of tumor were more than double as compared to single agent treated mice. Its superior activity has also been demonstrated, in cetuximab-refractory CRC models. Conclusions These results provide experimental evidence that more efficient and complete EGFR blockade may determine better antitumor activity and could contribute to prevent and/or overcome acquired resistance to EGFR inhibitors.

    This study was conducted to evaluate the nitrogen use efficiency and "1"3C isotope discrimination of rice mutant lines viz. NMR151 and NMR152. Both cultivars are developed under rice radiation mutagenesis programme for adaptability to aerobic conditions. In the present study, NMR151 and NMR152 were grown under conditions of varying water potentials and nitrogen levels in a field. Two water potentials and three nitrogen rates in a completely randomized design with three replications were carried out. The rice mutants were grown for 110 days under two water potentials, (i) Field capacity from 0 to 110 DAS [FC], and (ii) Field capacity from 0 to 40 DAS and 30 % dry of field capacity from 41 to 110 DAS [SS] and three nitrogen rates, (i) 0 kg N/ ha (0N), (ii) 60 kg N/ ha (60N), and (iii) 120 kg N/ ha (120N). "1"5N isotopic tracer technique was used in this study, whereby the "1"5N labeled urea fertilizer 5.20 % atom excess (a.e) was utilized as a tracer for nitrogen use efficiency (NUE) study. "1"5N isotope presence in the samples was determined using emission spectrometry and percentage of total nitrogen was determined by the Kjeldahl method. "1"5N a.e values of the samples were used in the determination of the NUE. The value of "1"3C isotope discrimination (Δ"1"3C) in the sample was determined using isotope ratio mass spectrometry (IRMS). The "1"3C isotope discrimination technique was used as a tool to identify drought resistance rice cultivars with improves water use efficiency. The growth and agronomy data, viz. plant height, number of tillers, grain yield, straw yield, and 1000 grain weight also were recorded. Results from this study showed nitrogen rates imparted significant effects on yield (grain and straw) plant height, number of tillers and 1000 grain weight. Water potentials had significant effects only on 1000 grain weight and Δ"1"3C. The NUE for both mutant lines rice showed no significant different between treatments.

    The I15-1 beamline, the new side station to I15 at the Diamond Light Source, will be dedicated to the collection of atomic pair distribution function data. A Laue monochromator will be used consisting of three silicon crystals diffracting X-rays at a common Bragg angle of 2.83°. The crystals use the (1 1 1), (2 2 0), and (3 1 1) planes to select 40, 65, and 76 keV X-rays, respectively, and will be bent meridionally to horizontally focus the selected X-rays onto the sample. All crystals will be cut to the same optimized asymmetry angle in order to eliminate image broadening from the crystal thickness. Finite element calculations show that the thermal distortion of the crystals will affect the image size and bandpass.

    1994-01-01

    The temperature T c at which K 2 ZnBr 4 is predicted to transform from the paraelectric to the ferroelectric phase is 151 (19) K, based on the crystal structure determinations at 291 and 144 K by Fabry, Breczewski, Zuniga and Arnaiz and the Abrahams-Kurtz-Jamieson relationship. A dielectric and heat-capacity anomaly in this material at 155 K has been reported elsewhere. The locations reported for the ZnBr 2- 4 and K + ions fulfill the requirements of mirror plane symmetry above T c ; ionic displacements along the polar direction that approach but do not exceed 0.1 A and that violate the mirror symmetry on cooling through T c form the basis of the prediction and satisfy the structural criteria for ferroelectricity in the phase below the transition.

    The nucleon form factors have been investigated by physicists for decades because of their fundamental importance. The world data of the proton magnetic form factor GMp has been focused on Q2 lower than 5 GeV2 and they have large uncertainties at higher Q2. Jefferson Lab experiment E12-07-108 aims to improve the accuracy of the e ? p elastic cross section to better than 2% over a Q2 range of 7 ? 14 GeV2. From 2015 to 2016, the e ? p elastic cross section was measured over a wide range of Q2 from 0.66 ? 12.56 GeV2 at the Thomas Jefferson National Accelerator Facility in Virginia, USA. An unpolarized electron beam was scattered o? a cryogenic hydrogen target and the scattered electron was detected in the high resolution spectrometers. This thesis focuses on the cross section calculations of the data taken in the spring of 2015, where Q2 = 0.66, 1.10, 1.51 and 1.66 GeV2. At Q2 = 0.66 GeV2, an uncertainty < 3% was achieved and < 5% was achieved for the other three Q2 at the moment. The results were compared with the world data and the good agreement provides confidence for the experimental measurements at higher Q2.

    Causes of the well-documented association between low levels of cognitive functioning and many adverse neuropsychiatric outcomes, poorer physical health and earlier death remain unknown. We used linkage disequilibrium regression and polygenic profile scoring to test for shared genetic aetiology between cognitive functions and neuropsychiatric disorders and physical health. Using information provided by many published genome-wide association study consortia, we created polygenic profile scores for 24 vascular–metabolic, neuropsychiatric, physiological–anthropometric and cognitive traits in the participants of UK Biobank, a very large population-based sample (N=112 151). Pleiotropy between cognitive and health traits was quantified by deriving genetic correlations using summary genome-wide association study statistics and to the method of linkage disequilibrium score regression. Substantial and significant genetic correlations were observed between cognitive test scores in the UK Biobank sample and many of the mental and physical health-related traits and disorders assessed here. In addition, highly significant associations were observed between the cognitive test scores in the UK Biobank sample and many polygenic profile scores, including coronary artery disease, stroke, Alzheimer's disease, schizophrenia, autism, major depressive disorder, body mass index, intracranial volume, infant head circumference and childhood cognitive ability. Where disease diagnosis was available for UK Biobank participants, we were able to show that these results were not confounded by those who had the relevant disease. These findings indicate that a substantial level of pleiotropy exists between cognitive abilities and many human mental and physical health disorders and traits and that it can be used to predict phenotypic variance across samples.

    We report the discovery of a unique gravitational lens system, SDSS J2222+2745, producing five spectroscopically confirmed images of a z s = 2.82 quasar lensed by a foreground galaxy cluster at z l = 0.49. We also present photometric and spectroscopic evidence for a sixth lensed image of the same quasar. The maximum separation between the quasar images is 15.''1. Both the large image separations and the high image multiplicity are in themselves rare among known lensed quasars, and observing the combination of these two factors is an exceptionally unlikely occurrence in present data sets. This is only the third known case of a quasar lensed by a cluster, and the only one with six images. The lens system was discovered in the course of the Sloan Giant Arcs Survey, in which we identify candidate lenses in the Sloan Digital Sky Survey and target these for follow-up and verification with the 2.56 m Nordic Optical Telescope. Multi-band photometry obtained over multiple epochs from 2011 September to 2012 September reveals significant variability at the ∼10%-30% level in some of the quasar images, indicating that measurements of the relative time delay between quasar images will be feasible. In this lens system, we also identify a bright (g = 21.5) giant arc corresponding to a strongly lensed background galaxy at z s = 2.30. We fit parametric models of the lens system, constrained by the redshift and positions of the quasar images and the redshift and position of the giant arc. The predicted time delays between different pairs of quasar images range from ∼100 days to ∼6 yr

    Abstract Pending the results of the 26062 EORTC trial, no standard of care exists for elderly patients with glioblastoma. Randomized controlled trials have provided evidence of a slight survival benefit for radiotherapy versus best supportive care (Keime-Guibert) and of lack of substantial benefit from single post-surgical treatment over each other. Treatment is still largely variable according to local practice. In this study we investigated the pattern of care and outcome in patients older than 65 diagnosed with glioblatoma in 3 hospitals in Lombardia and analyzed factors with impact on survival. 151 patients were included in this study, enrolled in Lecco Hospital, Niguarda Hospital and Neurooncology Unit of Fondazione IRCCS Istituto Neurologico Besta and undergoing surgery from 2004 to 2014. 91 were male, 60 female. Age range was 65 to 83, with a median value of 72. Concerning clinical variables, KPS was 70 or higher in 109 patients and lower in 42. 19 patients underwent biopsy, 14 partial resection and 118 total/subtotal resection as evaluated by the neurosurgeon. 114 patients were treated with radiotherapy and 97 with chemotherapy (all these 97 also received radiotherapy). 32 patients displayed seizures at disease onset. 22 patients did not receive antiepileptic treatment, while 129 were treated with antiepileptic drugs despite absence of seizures in 48. 40% of patients treated with antiepileptic drugs received enzyme-inducing drugs, 60% were treated with either VPA or levetiracetam. At disease progression, 22 patients received further treatment, including repeat surgery and/or second-line chemotherapy. In only 36 patients were molecular biology tests performed (IDH1 mutation). At univariate analysis, survival was longer in patients with higher KPS (p=0.02), those receiving partial/total surgery vs biopsy (p=0.03), those receiving total resection (p=0.003), those treated with radiotherapy (p<0.0001), chemotherapy (p<0.0001), those being treated at Istituto

    Large pericentric inversions in chromosome 10 are rare chromosomal aberrations with only few cases of familial inheritance. Such chromosomal rearrangements may lead to production of unbalanced gametes. As a result of a recombination event in the inversion loop, 2 recombinants with duplicated and deficient chromosome segments, including the regions distal to the inversion, may be produced. We report on 2 relatives in a family with opposite terminal chromosomal rearrangements of chromosome 10, i.e. rec(10)dup(10p)inv(10) and rec(10)dup(10q)inv(10), due to familial pericentric inversion inv(10)(p15.1q26.12). Based on array-CGH results, we characterized the exact genomic regions involved and compared the clinical features of both patients with previous reports on similar pericentric inversions and regional differences within 10p and 10q. The fact that both products of recombination are viable indicates a potentially high recurrence risk of unbalanced offspring. This report of unbalanced rearrangements in chromosome 10 in 2 generations confirms the importance of screening for terminal imbalances in patients with idiopathic intellectual disability by molecular cytogenetic techniques such as FISH, MLPA or microarrays. It also underlines the necessity for FISH to define structural characteristics of such cryptic intrachromosomal rearrangements and the underlying cytogenetic mechanisms. © 2014 S. Karger AG, Basel.

    Spectra of Lu obtained with a sliding spark discharge at peak currents of 50--500 A were recorded with a 10.7 m normal incidence spectrograph in the range of 500--2100 A. Intercomparison of spectra revealed a distinct separation of Lu III, IV, and V, the first two of which have already been anlayzed. The present work contains an interpretation of Lu V in which 419 lines are classified as transitions among 136 energy levels of the 4f 13 , 4f 12 5d, 4f 12 6s, and 4f 12 6p configurations. Calculated energy levels and eigenvectors, obtained with fitted values for the radial integrals, are given

    177 Lu complexation of DOTA and DTPA is investigated by the addition of Ca(II), Fe(II) and Zn(II). The 177 Lu complexation yield of DTPA was higher than that of DOTA in the presence of Ca(II), Fe(II) and Zn(II). Therefore, it was found that the 177 Lu complexation of DTPA was more advantageous compared with DOTA in the presence of competing metals, Ca, Fe and Zn. (author)

    Development of oral therapeutic radiopharmaceuticals is a new concept in radiopharmacy. Due to the interesting therapeutic properties of 177 Lu and oral bioavailability of maltolate (MAL) metal complexes, 177 Lu-maltolate ( 177 Lu-MAL) was developed as a possible therapeutic compound for ultimate oral administration. The specific activity of 2.6-3 GBq/mg was obtained by irradiation of natural Lu 2 O 3 sample with thermal neutron flux of 4x10 13 n.cm -2 .s -1 for Lu-177. The product was converted into chloride form which was further used for labeling maltol (MAL). At optimized conditions a radiochemical purity of about >99% was obtained for 177 Lu-MAL shown by ITLC (specific activity, 970-1000 Mbq/mmole). The stability of the labeled compound as well as the partition coefficient was determined in the final solution up to 24h. Biodistribution studies of Lu-177 chloride and 177 Lu-MAL were carried out in wild-type rats for post-oral distribution phase data. Lu-MAL is a possible therapeutic agent in human malignancies for the bone palliation therapy so the efficacy of the compound should be tested in various animal models.

    Temperature dependence of water vapour equilibrium pressure over the compounds of ErCl 3 ·6H-2O, TmCl 3 ·6H 2 O and LuCl 3 ·6H 2 O is studied by membrane method within the temperature range of 309-403 K. Dehydration process stoichiometry is determined thermogravimetrically under quasi-equilibrium conditions. All three compounds split off three molecules at the first stage of dehydration. ErCl 3 ·6H 2 O and TmCl 2 ·6H 2 O are very similar to terbium and disprosium chloride hexahydrates by vapour pressure value and dehydration enthalpy; enthalpy of the first dehydration stage is of the same character as those of nedymium, gadolinium and holmium chloride haxahydrates

    Er-Lu butyrates have been obtained. The crystals of the obtained salts had an identical shape of combinations of hexagonal prisms and pyramids. The values of the refraction index, measured by the method of circular screening and use of immersion liquids, were found to be close to each other in all the salts considered. The densities of the crystallohydrates of rare earth element butyrates, measured by the pycnometric method in isooctane, increases in the order of Er, Tm, Lu: 1.73; 1.74; 1.79 g/cm 3 , respectively. Infrared spectra of rare earth element butyrates were studied, and the main ware frequencies of maximum absorption were determined with a view of finding the character of the bond between the metal and the anion. A thermo-differential and a thermo-gravimetric investigation of rare earth element butyrates was carried out

    The spectra of total γ-absorption in the decays of some Lutecium, Thulium and Cesium isotopes have been measured. The probabilities for level population in the decay of the isotopes have been determined. The deduced beta strength functions reveal pronounced structure. Calculations of the strength functions using the Saxon-Woods potential and the residual Gamow-Teller interaction are presented. It is shown that in β + decay of light Thulium and Cesium isotopes the strength function comprises more than 70% of the Gamow-Teller excitations with μsub(tau) = +1. This result is the first direct observation of the Gamow-Teller resonance in β + decay of nuclei with Tsub(z) > O. (orig.)

    The high-pressure structural phase transition and pressure as well temperature induced elastic properties of rock salt to CsCl structures in semiconducting LuX (X = S, Se, and Te) chalcogenides compound have been performed using effective interionic interaction potential with emphasis on charge transfer interactions and covalent contribution. Estimated values of phase transition pressure and the volume discontinuity in pressure-volume phase diagram indicate the structural phase transition from ZnS to NaCl structure. From the investigations of elastic constants the pressure (temperature) dependent volume collapse/expansion, melting temperature TM, Hardness (HV), and young modulus (E) the LuX lattice infers mechanical stiffening, and thermal softening.

    A chemical separation procedure has been devised to isolate Lu from Purex dissolver solutions containing the neutron poison, Gd. The isolation procedure involves the removal of U and >Pu from a dissolver solution using tributylphosphate solvent extraction. If required, solvent extraction using di-(2-ethylhexyl) phosphoric acid can be employed to further purify the sample be removing alkali and alkali earth elements. Finally, Lu is chromatographically separated from Gd and rare earth fission products on a Dowex 50W-X8 resin column using an alpha-hydroxyisobutyrate eluant. The success of the chemical separation procedure has been demonstrated in the quantitative recovery of as little as 1.4 ng Lu from solutions containing a 5000-fold excess of Gd. Additionally, Lu has been isolated from synthetic dissolver samples containing U, Ba, Cs, and Gd. Thermal emission MS data indicated that the Lu fraction of the synthetic sample was free of Gd interference

    Full Text Available We report on the first cloning and nucleotide sequencing of an ERG11 allele from a clinical isolate of Candida kefyr cross-resistant to azole antifungals. It was recovered from a stem cell transplant patient, in an oncohematology unit exhibiting unexpected high prevalence of C. kefyr. Two amino acid substitutions were identified: K151E, whose role in fluconazole resistance was already demonstrated in Candida albicans, and E123Q, a new substitution never described so far in azole-resistant Candida yeast.

    Under basal conditions, the interaction of the cytosolic protein Kelch-like ECH-associated protein 1 (Keap1) with the transcription factor nuclear factor-E2-related factor 2 (Nrf2) results in a low level of expression of cytoprotective genes whose promoter region contains the antioxidant response element (ARE). In response to oxidants and electrophiles, Nrf2 is stabilized and accumulates in the nucleus. The mechanism for this effect has been proposed to involve thiol-dependent modulation of Keap1, leading to loss of its ability to negatively regulate Nrf2. We previously reported that falcarindiol (heptadeca-1,9(Z)-diene-4,6-diyne-3,8-diol), which occurs in Apiaceae and the closely related Araliaceae plants, causes nuclear accumulation of Nrf2 and induces ARE-regulated enzymes. Here, we report the mechanism of Nrf2 induction by falcarindiol. NMR analysis revealed that the conjugated diacetylene carbons of falcarindiol acted as electrophilic moieties to form adducts with a cysteine (Cys) thiol. In addition, using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and circular dichroism spectroscopy, it was demonstrated that falcarindiol alkylated Cys residues in Keap1 and altered the Keap1 secondary structure. Transfection studies using the purified Keap1 protein, a luciferase reporter construct, and an Nrf2-expressing plasmid indicated that the intact Keap1 protein suppressed Nrf2-mediated ARE-luciferase activity. On the other hand, the falcarindiol-alkylated Keap1 protein did not suppress such activity. Treatment of HEK293 cells overexpressing Keap1 with falcarindiol generated a high molecular weight (HMW) form of Keap1. Furthermore, the Cys151 residue in Keap1 was found to be uniquely required for not only the formation of HMW Keap1 but also an increase in ARE-luciferase activity by falcarindiol. Our results demonstrate that falcarindiol having conjugated diacetylene carbons covalently modifies the Cys151 residue in Keap1 and that the

    The Moessbauer technique was used to investigate the hyperfine interaction of /sup 161/Dy and /sup 151/Eu in cubic rare earth tungsten bronzes: Dysub(0.18)WO/sub 3/ and Eusub(0.18)WO/sub 3/. Well resolved hfs spectrum was obtained at 4.2 K for Dysub(0.18)WO/sub 3/. The effective hf field approximation sufficed to interpret the spectrum. The obtained hyperfine interaction parameters were: -g/sub 0/..beta..sub(N)Hsub(eff)=(805+-19) Mc/s and e/sup 2/qQ/sub 0//4 = (506+-56) Mc/s. These results imply that ground doublet of Dy/sup +3/ ion in bronze is a Kramers doublet Vertical Bar+-15/2> with asymmetrical hyperfine tensor Asub(z) non equal to 0, Asub(x) = Asub(y) = 0 and that local crystalline field at RE metal in tungsten bronze at 4.2 K cannot be cubic. From ME absorption spectra of Eusub(0.18)WO/sub 3/ taken at 4.2 K, 78 K and 300 K the values of quadrupole interaction constants for bronze lattice and its temperature dependence were obtained. These data indicate that a phase transition from the high temperature ideal perovskite structure to a distorted one occurs in RE bronzes and that the distortion concerns the nearest tungsten-oxygen environment of RE ion.

    Inverted duplications associated with terminal deletions are complex anomalies described in an increasing of chromosome ends. We report on the cytogenetic characterization of the first de novo inv dup del(4) with partial 4p duplication and 4q deletion in a girl with clinical signs consistent with "recombinant 4 syndrome". This abnormality was suspected by banding, but high-resolution molecular cytogenetic investigations allowed us to define the breakpoints of the rearrangement. The terminal duplicated region extending from 4p15.1 to the telomere was estimated to be 29.27 Mb, while the size of the terminal deletion was 3.114 Mb in the 4q35.1 region. Until now, 10 patients with duplicated 4p14-p15 and deleted 4q35 chromosome 4 have been described. In all cases the abnormal chromosome 4 was derived from a pericentric inversion inherited from one of the parents. In conclusion, we have identified the first case of inv dup del(4) with normal parents suggesting that, often, terminal duplications or terminal deletions mask complex rearrangements.

  14. Ia-restricted B-B cell interaction. I. The MHC haplotype of bone marrow cells present during B cell ontogeny dictates the self-recognition specificity of B cells in the polyclonal B cell activation by a B cell differentiation factor, B151-TRF2

    International Nuclear Information System (INIS)

    Ono, S.; Takahama, Y.; Hamaoka, T.

    1987-01-01

    We have demonstrated that B cell recognition of Ia molecules is involved in polyclonal B cell differentiation by B151-TRF2. The present study was undertaken to examine the Ia recognition specificity of B151-TRF2-responsive B cells in fully major histocompatibility complex (MHC)-allogeneic P1----P2, semiallogeneic P1----(P1 x P2)F1, and double donor (P1 + P2)----(P1 x P2)F1 and (P1 + P2)----P1 radiation bone marrow chimeras. The B cells from both P1----P2 and P1----(P1 x P2)F1 chimeras could give rise to in vitro immunoglobulin M-producing cells upon stimulation with B151-TRF2 comparable in magnitude to that of normal P1 B cells, and their responses were inhibited by anti-I-AP1 but not by anti-I-AP2 monoclonal antibody even in the presence of mitomycin C-treated T cell-depleted P2 spleen cells as auxiliary cells. In contrast, the B151-TRF2 responses of P1 B cells isolated from both (P1 + P2)----(P1 x P2)F1 and (P1 + P2)----P1 double bone marrow chimeras became sensitive to the inhibition of not only anti-I-AP1 but also anti-I-AP2 monoclonal antibody only when the culture was conducted in the presence of P2 auxiliary cells, demonstrating that they adaptively differentiate to recognize as self-structures allogeneic as well as syngeneic Ia molecules. Moreover, the experiments utilizing B cells from H-2-congenic mice and B cell hybridoma clones as auxiliary cells revealed that B151-TRF2-responsive B cells recognize Ia molecules expressed on B cells. Taken together, these results demonstrate that B151-TRF2-responsive B cells recognize Ia molecules expressed by B cells as self-structures and that their self-recognition specificity is dictated by the MHC haplotype of bone marrow cells present during the B cell ontogeny but not by the MHC haplotype of a radiation-resistant host environment

  15. Clinical results of intravenous and intra-arterial peptide receptor radionuclide therapy (PRRT) using Y-90 and Lu-177 DOTA-TYR3-OCTREOTATE (Y-90 DOTA-TATE) in 151 patents with metastatic progressive neuroendocrine tumors (NET)

    We investigated the anti-tumor efficacy and adverse effects of the somatostatin analog octreotate labelled with Y-90 or Lu-177 in patients with progressive neuroendocrine tumors and severe tumour burden. 151 patients (69 f and 82 m, age range=19-81 yrs), 307 administrations, Mean activity per cycle 3.35 GBq (max. 7000 MBq) and time between cycles 3 to 6 months. 7 pts received intra-arterial injections (8 cycles). All patients were selected based on high SST-R expression as proven by immunohistochemistry and Ga-68 DOTA-NOC receptor PET/CT or somatostatin scintigraphy. Re-staging was done using Ga-68 DOTA-NOC PET/CT, MRI, FDG-PET/CT, SST-R scintigraphy, F-18-Fluoride-PET/CT, renal scintigraphy (MAG 3), GFR measurements (DTPA) and monthly laboratory tests (haematology, liver enzymes, renal parameters, tumour markers). Results revealed 2 patients with complete remission (de novo therapy), Partial remission (PR) in 37 %, Stable disease (SD) in 52 % and disease progression (DP) in 11%. Objective tumour response (including improvement of symptoms) was seen in 85 % of the patients. A few adverse effects were also noted: Nausea and vomiting occurred in 35 % of female, and in 15 % of male patients. Anemia, leucocytopenia and thrombocytopenia (G2-3) observed in less than <15 %. None of the pts developed myelodysplastic syndrome. No hair loss was observed. We conclude that PRRT with Y-90/Lu-177 DOTA-TATE results in a high response rate with significant improvement of clinical symptoms; the treatment is tolerated with low toxicity and few adverse effects and shows promising results also in pts with progressive neuroendocrine tumours after biological treatment(interferon/sandostatin) or after chemotherapy. Renal toxicity can be reduced by prolonging the intervals between therapy cycles and reducing the maximum activity per cycle ('Bad Berka concept')

    Science.gov (United States)

    Dilmi, S.; Saib, S.; Bouarissa, N.

    2018-06-01

    Structural, electronic, electron-phonon coupling and superconducting properties of the intermetallic compound LuC2 are investigated by means of ab initio pseudopotential plane wave method within the generalized gradient approximation. The calculated equilibrium lattice parameters yielded a very good accord with experiment. There is no imaginary phonon frequency in the whole Brillouin zone supporting thus the dynamical stability in the material of interest. The average electron-phonon coupling parameter is found to be 0.59 indicating thus a weak-coupling BCS superconductor. Using a reasonable value of μ* = 0.12 for the effective Coulomb repulsion parameter, the superconducting critical temperature Tc is found to be 3.324 which is in excellent agreement with the experimental value of 3.33 K. The effect of the spin-orbit coupling on the superconducting properties of the material of interest has been examined and found to be weak.

    2015-09-03

    By using ab initio molecular dynamics, we investigate the solvent shell structure of La(3+) and Lu(3+) ions immersed in two ionic liquids, ethylammonium nitrate (EAN) and its hydroxy derivative (2-ethanolammonium nitrate, HOEAN). We provide the first study of the coordination properties of these heavy metal ions in such a highly charged nonacqueous environment. We find, as expected, that the coordination in the liquid is mainly due to nitrate anions and that, due to the bidentate nature of the ligand, the complexation shell of the central ion has a nontrivial geometry and a coordination number in terms of nitrate molecules that apparently violates the decrease of ionic radii along the lanthanides series, since the smaller Lu(3+) ion seems to coordinate six nitrate molecules and the La(3+) ion only five. A closer inspection of the structural features obtained from our calculations shows, instead, that the first shell of oxygen atoms is more compact for Lu(3+) than for La(3+) and that the former coordinates 8 oxygen atoms while the latter 10 in accord with the typical lanthanide's trend along the series and that their first solvation shells have a slight irregular and complex geometrical pattern. When moving to the HOEAN solutions, we have found that the solvation of the central ion is possibly also due to the cation itself through the oxygen atom on the side chain. Also, in this liquid, the coordination numbers in terms of oxygen atoms in both solvents is 10 for La(3+) and 8 for Lu(3+).

    Results for pure Sc show that the maximum and minimum in the susceptibility discovered earlier are enhanced as the impurity level of iron in scandium decreases. The Stoner enhancement factor, calculated from low-temperature heat capacity data, susceptibility data, and band-structure calculations show Sc to be a strongly enhanced paramagnet. Below 2 0 K, the magnetic anisotropy between the hard and easy directions of scandium decreases linearly with decreasing temperature, tending toward zero at 0 K. The large increase in the susceptibility of Sc at lower temperatures indicates magnetic ordering. Pure Lu and Lu-H alloys showed an anisotropy in susceptibility vs orientation; thus the samples were not random polycrystalline samples. Pure Lu shows the shallow maximum and minimum, but the increase in susceptibility at low temperatures is larger than previously observed. The susceptibility-composition dependence of the Lu-H alloys also did not match other data. The susceptibility-composition dependence does not match the composition dependence of the electronic specific heat constant below 150 K, showing the electronic specific heat is being affected by terms other than phonon-electron and pure electron-electron interactions

    In this paper, phosphors of LuF{sub 3}:Eu{sup 3+}/Tb{sup 3+} have been successfully synthesized with small chelator ethylenediaminetetra acetic acid (EDTA) or amphiphilic polymer (polyethylene glycol, PEG-1000) as templates via a hydrothermal method. X-ray powder diffraction (XRD), scanning electronic microscope (SEM), and photo-luminescent spectra techniques (PL) were used to characterize the as-prepared samples. XRD patterns showed that well crystallized lanthanide fluorides with hexagonal phase were achieved. SEM images revealed that different regular microstructures were achieved. The photo-luminescent properties of LuF{sub 3}:Eu{sup 3+} demonstrated that there are significant energy transfers from fluorides to Eu{sup 3+}. The results presented that EDTA as the template will lead to the highest emission intensities. -- Highlights: • Various templates were used to synthesize LuF{sub 3}:Eu{sup 3+}/Tb{sup 3+}. • All the phosphors were red or green emissive. • Different morphologies were acquired and controllable.

    Full Text Available Structural, elastic, electronic and thermodynamic properties of ternary cubic filled skutterudite compound were calculated. We have computed the elastic modulus and its pressure dependence. From the elastic parameter behavior, it is inferred that this compound is elastically stable and ductile in nature. Through the quasi-harmonic Debye model, in which phononic effects are considered, the effect of pressure P (0 to 50 GPa and temperature T (0 to 3000 °C on the lattice constant, elastic parameters, bulk modulus B, heat capacity, thermal expansion coefficient α, internal energy U, entropy S, Debye temperature θD, Helmholtz free energy A, and Gibbs free energy G are investigated.

  15. Etudes optiques de nouveaux materiaux laser: Des orthosilicates dopes a l'ytterbium: Le yttrium (lutetium,scandium) pentoxide de silicium

    Science.gov (United States)

    Denoyer, Aurelie

    La decouverte et l'elaboration de nouveaux materiaux laser solides suscitent beaucoup d'interet parmi la communaute scientifique. En particulier les lasers dans la gamme de frequence du micron debouchent sur beaucoup d'applications, en telecommunication, en medecine, dans le domaine militaire, pour la, decoupe des metaux (lasers de puissance), en optique non lineaire (doublage de frequence, bistabilite optique). Le plus couramment utilise actuellement est le Nd:YAG dans cette famille de laser, mais des remplacants plus performants sont toujours recherches. Les lasers a base d'Yb3+ possedent beaucoup d'avantages compares aux lasers Nd3+ du fait de leur structure electronique simple et de leur deterioration moins rapide. Parmi les matrices cristallines pouvant accueillir l'ytterbium, les orthosilicates Yb:Y 2SiO5, Yb:Lu2SiO5 et Yb:Sc2SiO 5 se positionnent tres bien, du fait de leur bonne conductivite thermique et du fort eclatement de leur champ cristallin necessaire a l'elaboration de lasers quasi-3 niveaux. De plus l'etude fine et systematique des proprietes microscopiques de nouveaux materiaux s'avere toujours tres interessante du point de vue de la recherche fondamentale, c'est ainsi que de nouveaux modeles sont concus (par exemple pour le champ cristallin) ou que de nouvelles proprietes inhabituelles sont decouvertes, menant a de nouvelles applications. Ainsi d'autres materiaux dopes a l'ytterbium sont connus pour leurs proprietes de couplage electron-phonon, de couplage magnetique, d'emission cooperative ou encore de bistabilite optique, mais ces proprietes n'ont encore jamais ete mises en evidence dans Yb:Y 2SiO5, Yb:Lu2SiO5 et Yb:Sc2SiO 5. Ainsi, cette these a pour but l'etude des proprietes optiques et des interactions microscopiques dans Yb:Y2SiO 5, Yb:Lu2SiO5 et Yb:Sc2SiO5. Nous utilisons principalement les techniques d'absorption IR et de spectroscopie Raman pour determiner les excitations du champ cristallin et les modes de vibration dans le materiau. Des mesures optiques sous champ magnetique ont egalement ete effectuees dans le but de caracteriser le comportement de ces excitations lorsqu'elles sont soumises a l'effet Zeeman. La resonance paramagnetique electronique a permis de completer cette etude de l'eclatement Zeeman suivant toutes les orientations du cristal. Enfin la fluorescence par excitation selective et la fluorescence induite par Raman FT, completent la description des niveaux d'energie et revelent l'existence d'emission cooperative de deux ions Yb3+ et de transferts d'energie. Les resultats de cette these apportent une contribution originale dans le domaine des nouveaux materiaux lasers par l'etude et la comprehension des interactions fines et des proprietes microscopiques d'un materiau en particulier. Ils debouchent a la fois sur des applications possibles dans le domaine de l'optique et des lasers, et sur la comprehension d'aspects fondamentaux. Cette these a prouve l'interet de ces matrices pour leur utilisation comme lasers solides: un fort eclatement du champ cristallin favorable a l'elaboration de laser quasi-3 niveaux, et de larges bandes d'absorption (dues a un fort couplage electron-phonon et a des raies satellites causees par une interaction d'echange entre deux ions Yb3+) qui permettent la generation d'impulsions laser ultra-courtes, l'accordabilite du laser, etc. De plus la miniaturisation des lasers est possible pour l'optique integree grace a des couches minces synthetisees par epitaxie en phase liquide dont nous avons demontre la tres bonne qualite structurale et l'ajustement possible de certains parametres. Nous avons reconstruit le tenseur g du niveau fondamental (qui donne des informations precieuses sur les fonctions d'onde), ceci dans le but d'aider les theoriciens a concevoir un modele de champ cristallin valide. Plusieurs mecanismes de transferts d'energie ont ete mis en evidence: un mecanisme de relaxation d'un site vers l'autre, un mecanisme d'emission cooperative, et un mecanisme d'excitation de l'Yb3+ par le Tm3+ (impurete presente dans le materiau). Ces transferts sont plutot nefastes pour la fabrication d'un laser mais sont interessants pour l'optique non lineaire (doublage de frequence, memoires optiques). Enfin, plusieurs elements (le couplage magnetique de paire, le couplage electron-phonon et l'emission cooperative) nous ont permis de conclure sur le caractere covalent de la matrice. Nous avons d'ailleurs demontre ici le role de la covalence dans l'emission cooperative, transition habituellement attribuee aux interactions multipolaires electriques.

    Since prostate-specific membrane antigen (PSMA) has been identified as a diagnostic target for prostate cancer, many urea-based small PSMA-targeting molecules were developed. First, the clinical application of these Ga-68 labelled compounds in positron emission tomography (PET) showed their diagnostic potential. Besides, the therapy of prostate cancer is a demanding field, and the use of radiometals with PSMA bearing ligands is a valid approach. In this work, we describe the synthesis of a new PSMA ligand, CHX-A''-DTPA-DUPA-Pep, the subsequent labelling with Ga-68, Lu-177 and Y-90 and the first in vitro characterization. In cell investigations with PSMA-positive LNCaP C4-2 cells, KD values of ≤14.67 ± 1.95 nM were determined, indicating high biological activities towards PSMA. Radiosyntheses with Ga-68, Lu-177 and Y-90 were developed under mild reaction conditions (room temperature, moderate pH of 5.5 and 7.4, respectively) and resulted in nearly quantitative radiochemical yields within 5 min.

    We have developed a set of modeled nuclear reaction cross sections for use in radiochemical diagnostics. Systematics for the input parameters required by the Hauser-Feshbach statistical model were developed and used to calculate neutron induced nuclear reaction cross sections for targets ranging from Terbium (Z = 65) to Rhenium (Z = 75). Of particular interest are the cross sections on Tm, Lu, and Ta including reactions on isomeric targets.

    Here we present the guideline for the treatment of neuroendocrine tumors using Lu-177-DOTA-TATE on the basis of radiation safety aspects in Japan. This guideline was prepared by a study supported by Ministry of Health, Labour, and Welfare, and approved by Japanese Society of Nuclear Medicine. Lu-177-DOTA-TATE treatment in Japan should be carried out according to this guideline. Although this guideline is applied in Japan, the issues for radiation protection shown in this guideline are considered internationally useful as well. Only the original Japanese version is the formal document.

    Few studies have been published on the safety and feasibility of synchronous use of peptide receptor radionuclide therapy (PRRNT), as source of internal radiation therapy, in combination with chemotherapy. In this study we reported a 53-year-old man with stage IV Merkel cell carcinoma (MCC), who underwent synchronous internal radiation therapy and chemotherapy. Based on presumable poor prognosis with chemotherapy only, functional similarities of MCC with other neuroendocrine tumors and available evidence of effectiveness and safety of synchronous use of external beam radiation therapy and chemotherapy in treatment of high-risk MCC patients, our interdisciplinary neuroendocrine tumor board recommended him to add PRRNT to his ongoing chemotherapy. He received 2 courses of 177 Lu-DOTATATE(1, 4, 7, 10-Tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid-1-D-Phe1-Tyr3-Thr8-octreotide) in combination with ongoing 8 cycles of liposomal doxorubicin based on standard protocols. Response to therapy was evaluated by 18 F-fluorodeoxyglucose ( 18 F-FDG) and 68 gallium-somatostatin-receptor PET/CT. There was an impressive improvement of the clinical symptoms. However, follow-up positron emission tomography (PET)/CT studies showed mixed pattern of response. Synchronous use of PRRNT and radiosensitizing chemotherapy seems safe and feasible in high risk MCC patients, however, further prospective studies and clinical trials are warranted to provide reliable evidence of possible pitfalls and effectiveness of PRRNT and 68 Ga-somatostatin-receptor PET/CT in the management of MCC.

    The L1 cell adhesion molecule (L1CAM) is considered a valuable target for therapeutic intervention in different types of cancer. Recent studies have shown that anti-L1CAM radioimmunotherapy (RIT) with 67 Cu- and 177 Lu-labelled internalising monoclonal antibody (mAb) chCE7 was effective in the treatment of human ovarian cancer xenografts. In this study, we directly compared the therapeutic efficacy of anti-L1CAM RIT against human ovarian cancer under equitoxic conditions with the radiolanthanide 177 Lu and the potential alternative 161 Tb in an ovarian cancer therapy model. Tb was produced by neutron bombardment of enriched 160 Gd targets. 161 Tb and 177 Lu were used for radiolabelling of DOTA-conjugated antibodies. The in vivo behaviour of the radioimmunoconjugates (RICs) was assessed in IGROV1 tumour-bearing nude mice using biodistribution experiments and SPECT/CT imaging. After ascertaining the maximal tolerated doses (MTD) the therapeutic impact of 50 % MTD of 177 Lu- and 161 Tb-DOTA-chCE7 was evaluated in groups of ten mice by monitoring the tumour size of subcutaneous IGROV1 tumours. The average number of DOTA ligands per antibody was 2.5 and maximum specific activities of 600 MBq/mg were achieved under identical radiolabelling conditions. RICs were stable in human plasma for at least 48 h. 177 Lu- and 161 Tb-DOTA-chCE7 showed high tumour uptake (37.8-39.0 %IA/g, 144 h p.i.) with low levels in off-target organs. SPECT/CT images confirmed the biodistribution data. 161 Tb-labelled chCE7 revealed a higher radiotoxicity in nude mice (MTD: 10 MBq) than the 177 Lu-labelled counterpart (MTD: 12 MBq). In a comparative therapy study with equitoxic doses, tumour growth inhibition was better by 82.6 % for the 161 Tb-DOTA-chCE7 than the 177 Lu-DOTA-chCE7 RIT. Our study is the first to show that anti-L1CAM 161 Tb RIT is more effective compared to 177 Lu RIT in ovarian cancer xenografts. These results suggest that 161 Tb is a promising candidate for future clinical applications in combination with internalising antibodies. (orig.)

    Substance P (SP) is an 11- amino acid neuropeptide, which is known as an important member of the family of the tachykinins, characterized by the C-terminal sequence Phe-X-Gly-Leu-Met-NH2. Radiolabeled SP has been described and proposal for detection and treatment of diseases such as arthritis and tumors. SP is the most important target of neurokinin 1 (NK-1) receptors, over expressed in malignant gliomas. 177 Lu is commonly used in the production of radiopharmaceuticals for treatment of neuroendocrine tumors and is a radionuclide with favorable properties for endo radiotherapy. The half-life of 177 Lu is 6.75 days and it emits b- particles of 497 keV average energy. Moreover, 177 Lu also emits g radiation of 208 keV average energy, which makes imaging diagnosis possible. There are few studies describing radiolabeled SP analogs in literature and the objective of this work was to study the radiolabeling conditions and the stability of SP complexed to DOTA chelator, using 177 Lu as radionuclide, in order to determine the best radiolabeling methodology. A high radiochemical purity (> 95%) and high specific activity of DOTA-SP was achieved when the reaction time was 30 minutes, the temperature was 90 deg C, the mass of DOTA-SP was 10 mg and 177 Lu activity was 185 MBq. These conditions extrapolate will be used in future experiments with high activity and also in in vitro and in vivo studies involving glioma models. (author)

  15. Dose rate analysis for Tank 101 AZ (Project W151)

    International Nuclear Information System (INIS)

    Schwarz, R.A.; Hillesland, K.E.; Carter, L.L.

    1994-11-01

    This document describes the expected dose rates for modification to tank 101 AZ including modifications to the steam coil, mixer pump, and temperature probes. The thrust of the effort is to determine dose rates from: modification of a steam coil and caisson; the installation of mixer pumps; the installation of temperature probes; and estimates of dose rates that will be encountered while making these changes. Because the dose rates for all of these configurations depend upon the photon source within the supernate and sludge, comparisons were also made between measured dose rates within a drywell and the corresponding calculated dose rates. The calculational tool used is a Monte Carlo (MCNP 2 ) code since complicated three dimensional geometries are involved. A summary of the most important results of the entire study is given in Section 2. The basic calculational geometry model of the tank is discussed in Section 3, along with a tabulation of the photon sources that were used within the supernate and the sludge, and a discussion of uncertainties. The calculated dose rates around the steam coil and caisson before and after modification are discussed in Section 4. The configuration for the installation of the mixer pumps and the resulting dose rates are given in Section 5. The predicted changes in dose rates due to a possible dilution of the supernate source are given in Section 6. The calculational configuration used to model the installation of temperature probes and the resulting predicted dose rates are discussed in Section 7. Finally, comparisons of measured to calculated dose rates within a drywell are summarized in Section 8. Extended discussions of calculational models and Monte Carlo optimization techniques used are included in Appendix A

The europium compounds are reported for the first time and their structures were refined from single crystal X-ray diffractometer data: Sr{sub 2}Au{sub 6}Zn{sub 3} type, R anti 3c, a = 837.7(1), c = 2184.5(4) pm, wR2 = 0.0293, 572 F{sup 2} values for Eu{sub 2}Au{sub 6.04}Zn{sub 2.96} and a = 838.1(2), c = 2191.7(5) pm, wR2 = 0.0443, 513 F{sup 2} values for Eu{sub 2}Au{sub 6.07}Ga{sub 2.93} with 20 variables per refinement. The structures consist of a three-dimensional gold network with a 6R stacking sequence, similar to the respective diamond polytype. The cavities of the network are filled in a ratio of 2:1 by strontium (europium) atoms and Ga{sub 3} (Zn{sub 3}) triangles in an ordered manner. Sr{sub 2}Au{sub 6}Zn{sub 3} and Sr{sub 2}Au{sub 6}Ga{sub 3} are diamagnetic with room temperature susceptibilities of -3.5 x 10{sup -4} emu mol{sup -1}. Temperature dependent susceptibility and {sup 151}Eu Moessbauer spectroscopic measurements show a stable divalent ground state for both europium compounds. Eu{sub 2}Au{sub 6}Zn{sub 3} and Eu{sub 2}Au{sub 6}Ga{sub 3} order antiferromagnetically below Neel temperatures of 16.3 and 12.1 K, respectively. Anisotropic electrical conductivity of Sr{sub 2}Au{sub 6}Ga{sub 3} is proven by an alignment of the crystallites in the magnetic field. Orientation-dependent {sup 69;71}Ga NMR experiments combined with quantum mechanical calculations (QM) give evidence for a highly anisotropic charge distribution of the Ga atoms.

    The solvent extraction of lanthanides(III)(Ln = Er, Yb, Lu) by 1-phenyl-3-methyl-4-benzoyl-pyrazolone-5 (HL) in carbon tetrachloride from aqueous-methanol phase was investigated. The equilibrium constants for the extraction from aqueous-50 % (ν/ν) methanol phase (K ex ), two-phase stability constants of the complexes LnL 3 (β 3 * ) and stability constants of complexes LnL 2+ , LnL 2 + , LnL 3 (β n )(Ln = Yb, Lu) were calculated. It was confirmed that the addition of methanol to the aqueous phase causes a synergistic effect. The influence of methanol on the dissociation constant of HPMBP (K a ) and the distribution constant of HPMBP (p HL ) between carbon tetrachloride and water-methanol solutions was investigated.

    An algebraic formalism, developed with V. Glaser and R. Stora for the study of the generalized retarded functions of quantum field theory, is used to prove a factorization theorem which provides a complete description of the generalized retarded functions associated with any tree graph. Integrating over the variables associated to internal vertices to obtain the perturbative generalized retarded functions for interacting fields arising from such graphs is shown to be possible for a large category of space–times.

    The growing awareness of climate change/global warming and continuing concerns regarding stratospheric ozone depletion will require future measurements and standards for many compounds, in particular halocarbons that are linked to these issues. In order to track and control the emissions of these species globally in the atmosphere, it is necessary to demonstrate measurement equivalence at the highest levels of accuracy for assigned values of standards. This report describes the results of a pilot study between National Metrology Institutes and atmospheric research laboratories for several of the more important halocarbons at atmospheric concentration levels. The comparison includes the chlorofluorocarbons (CFCs) dichlorodifluoromethane (CFC 12), trichlorofluoromethane (CFC 11), and 1,1,2-trichlorotrifluoroethane (CFC 113); the hydrochlorofluorocarbons (HCFCs) chlorodifluoromethane (HCFC 22) and 1-chloro-1,1-difluoroethane (HCFC 142b); and the hydrofluorocarbon (HFC) 1,1,1,2-tetrafluoroethane (HFC 134a), all in a dried whole air sample. The objective of this key comparison is to compare the measurement capabilities of the participants for these halocarbons at trace atmospheric levels. Main text.

    Gastroesophageal reflux disease (GERD) is recognized as one of the most common disorders of the upper gastrointestinal tract (GIT). The best choice of management for advanced GERD is laparoscopic surgery. To compare and evaluate the results of surgical treatment of GERD patients operated on using two different techniques. Between 2001 and 2012, 353 patients (211 female and 142 male), aged 17-76 years (mean 44), underwent laparoscopic antireflux surgery. The study included patients who underwent a Toupet fundoplication or Wroblewski Tadeusz procedure (WTP). The mean age of the group was 47.77 years (17-80 years). Forty-nine (32.45%) patients had severe symptoms, 93 (61.58%) had mild symptoms and 9 (5.96%) had a single mild but intolerable sign of GERD. Eighty-six (56.95%) patients had a Toupet fundoplication and 65 (43.04%) had a WTP. The follow-up period was 18-144 months. The average operating time for Toupet fundoplication and the WTP procedure was 164 min (90-300 min) and 147 min (90-210 min), respectively. The perioperative mortality rate was 0.66%. The average post-operative hospitalization period was 5.4 days (2-16 post-operative days (POD) = Toupet) vs. 4.7 days (2-9 POD = WTP). No reoperations were performed. No major surgical complications were identified. Wroblewski Tadeusz procedure due to a low percentage of post-operative complications, good quality of life of patients and a zero recurrence rate of hiatal hernia should be a method of choice.

  8. SU-E-T-151: Breathing Synchronized Delivery (BSD) Planning for RapicArc Treatment

    International Nuclear Information System (INIS)

    Lu, W; Chen, M; Jiang, S

    2015-01-01

    Purpose: To propose a workflow for breathing synchronized delivery (BSD) planning for RapicArc treatment. Methods: The workflow includes three stages: screening/simulation, planning, and delivery. In the screening/simulation stage, a 4D CT with the corresponding breathing pattern is acquired for each of the selected patients, who are able to follow their own breathing pattern. In the planning stage, one breathing phase is chosen as the reference, and contours are delineated on the reference image. Deformation maps to other phases are performed along with contour propagation. Based on the control points of the initial 3D plan for the reference phase and the respiration trace, the correlation with respiration phases, the leaf sequence and gantry angles is determined. The beamlet matrices are calculated with the corresponding breathing phase and deformed to the reference phase. Using the 4D dose evaluation tool and the original 3D plan DVHs criteria, the leaf sequence is further optimized to meet the planning objectives and the machine constraints. In the delivery stage, the patients are instructed to follow the programmed breathing patterns of their own, and all other parts are the same as the conventional Rapid-Arc delivery. Results: Our plan analysis is based on comparison of the 3D plan with a static target (SD), 3D plan with motion delivery (MD), and the BSD plan. Cyclic motion of range 0 cm to 3 cm was simulated for phantoms and lung CT. The gain of the BSD plan over MD is significant and concordant for both simulation and lung 4DCT, indicating the benefits of 4D planning. Conclusion: Our study shows that the BSD plan can approach the SD plan quality. However, such BSD scheme relies on the patient being able to follow the same breathing curve that is used in the planning stage during radiation delivery. Funded by Varian Medical Systems

    Quality control (QC) in medical imaging is an ongoing process and not just a series of infrequent evaluations of medical imaging equipment. The QC process involves designing and implementing a QC program, collecting and analyzing data, investigating results that are outside the acceptance levels for the QC program, and taking corrective action to bring these results back to an acceptable level. The QC process involves key personnel in the imaging department, including the radiologist, radiologic technologist, and the qualified medical physicist (QMP). The QMP performs detailed equipment evaluations and helps with oversight of the QC program, the radiologic technologist is responsible for the day-to-day operation of the QC program. The continued need for ongoing QC in digital radiography has been highlighted in the scientific literature. The charge of this task group was to recommend consistency tests designed to be performed by a medical physicist or a radiologic technologist under the direction of a medical physicist to identify problems with an imaging system that need further evaluation by a medical physicist, including a fault tree to define actions that need to be taken when certain fault conditions are identified. The focus of this final report is the ongoing QC process, including rejected image analysis, exposure analysis, and artifact identification. These QC tasks are vital for the optimal operation of a department performing digital radiography

    Abella, V.; Gallardo, S.; Verdu, G.

    2010-01-01

    In this work, an overview of the results obtained in the simulation of an Upper Head Small Break Loss-Of-Coolant-Accident (SBLOCA) under the assumption of total failure of High Pressure Injection System (HPIS) in the Large Scale Test Facility (LSTF) is provided. In previous works, an SBLOCA located in the Pressure Vessel (PV) Lower Plenum was simulated with TRACE. In that case, an asymmetrical steam generator secondary-side depressurization was produced as an accident management action at the Steam Generator in loop without pressurizer after the generation of safety injection signal to achieve a determined depressurization rate in the primary system. The new SBLOCA scenario has been simulated and results compared with experimental values, with the purpose of completing the analysis of PV SBLOCA. This study is developed in the frame of the OECD/NEA ROSA Project Test 6-1 (SB-PV-9 in JAEA). Finally, the present paper represents a contribution for the study of safety analysis of vessel SBLOCAs and the assessment of the predictability of thermal-hydraulic codes like TRACE. (authors)

    A magnetic resonance (MR) compatible positron emission tomography (PET) insert has been developed in our laboratory for simultaneous small animal PET/MR imaging. This system is based on lutetium oxyorthosilicate (LSO) scintillator arrays with position-sensitive avalanche photodiode (PSAPD) photodetectors. The PET performance of this insert has been measured. The average reconstructed image spatial resolution was 1.51 mm. The sensitivity at the center of the field of view (CFOV) was 0.35%, which is comparable to the simulation predictions of 0.40%. The average photopeak energy resolution was 25%. The scatter fraction inside the MRI scanner with a line source was 12% (with a mouse-sized phantom and standard 35 mm Bruker 1H RF coil), 7% (with RF coil only) and 5% (without phantom or RF coil) for an energy window of 350–650 keV. The front-end electronics had a dead time of 390 ns, and a trigger extension dead time of 7.32 μs that degraded counting rate performance for injected doses above ~0.75 mCi (28 MBq). The peak noise-equivalent count rate (NECR) of 1.27 kcps was achieved at 290 μCi (10.7 MBq). The system showed good imaging performance inside a 7-T animal MRI system; however improvements in data acquisition electronics and reduction of the coincidence timing window are needed to realize improved NECR performance.

    People's differences in cognitive functions are partly heritable and are associated with important life outcomes. Previous genome-wide association (GWA) studies of cognitive functions have found evidence for polygenic effects yet, to date, there are few replicated genetic associations. Here we use data from the UK Biobank sample to investigate the genetic contributions to variation in tests of three cognitive functions and in educational attainment. GWA analyses were performed for verbal–numerical reasoning (N=36 035), memory (N=112 067), reaction time (N=111 483) and for the attainment of a college or a university degree (N=111 114). We report genome-wide significant single-nucleotide polymorphism (SNP)-based associations in 20 genomic regions, and significant gene-based findings in 46 regions. These include findings in the ATXN2, CYP2DG, APBA1 and CADM2 genes. We report replication of these hits in published GWA studies of cognitive function, educational attainment and childhood intelligence. There is also replication, in UK Biobank, of SNP hits reported previously in GWA studies of educational attainment and cognitive function. GCTA-GREML analyses, using common SNPs (minor allele frequency>0.01), indicated significant SNP-based heritabilities of 31% (s.e.m.=1.8%) for verbal–numerical reasoning, 5% (s.e.m.=0.6%) for memory, 11% (s.e.m.=0.6%) for reaction time and 21% (s.e.m.=0.6%) for educational attainment. Polygenic score analyses indicate that up to 5% of the variance in cognitive test scores can be predicted in an independent cohort. The genomic regions identified include several novel loci, some of which have been associated with intracranial volume, neurodegeneration, Alzheimer's disease and schizophrenia. PMID:27046643

  18. The chemistry of Magela Creek. A baseline for assessing change downstream of Ranger. Supervising Scientist report 151

    International Nuclear Information System (INIS)

    Klessa, D.A.

    2000-01-01

    The compositions of waters in Magela Creek upstream and downstream of Ranger uranium mine were reviewed. The water quality parameters examined were pH, electrical conductivity (EC) and turbidity, and dissolved calcium, magnesium, sodium, potassium, chloride, sulphate, ammonium, nitrate, copper, lead, manganese, zinc, uranium and radium-226. The frequency distributions of each of these parameters in waters upstream of the mine were characterised and statistically described to provide a baseline which allows a change in water chemistry downstream of the mine to be assessed. With the exception of pH, EC, turbidity, magnesium, calcium, sodium and manganese, data that comprise the baseline are not normally distributed. The frequency distributions of copper, lead, zinc, uranium and radium-226 forming the baseline are characterised by a large proportion of values at or near analytical detection limits and contamination in a relatively large proportion of the remainder. A comparison of upstream and downstream data shows that there is good conformity in pH, EC, turbidity, sodium, potassium and chloride. For calcium, nitrate, ammonium, lead, uranium, radium and zinc less than 40% of the downstream data fall outside the 20th and 80th baseline percentiles but in the ease of U, data are biased towards relatively high values. More than 40% of downstream magnesium and sulphate data are outside these percentile boundaries and are skewed towards relatively high concentrations. Copper, lead and zinc in mine waters (characterised by the composition of waters contained in the former RP4) do not appear to pose a risk as contaminants based upon the results of toxicity testing and water quality guideline trigger levels with risk minimised for greater than 1 in 20 dilution

    CHEM TV: Sunland, CA, 1998. 24.95, students; 59.95, faculty. This CD-ROM presents a series of interactive overviews and drills for students of organic chemistry. The material covered is generally taught in the first semester. This suite is much more than a simple presentation of material and, for students sufficiently motivated to take the time and work with the problems, will provide valuable review. Five interactive spaces are provided: concentration drills that emphasize recall of related structures/names, reagents/reactions, and stereochemistry; a structural review based on epinephrine; interactive synthesis projects; arcade game reagent review; and a set of timed self-tests. The CD-ROM installed and ran without problem on a Power PC Mac and on a Pentium running Windows 95. The program did fail to run when a student reviewing it switched to a very new version of Windows Quick Time. Most of the drills ran without a problem, although at times it was unclear how to respond to queries. I turned off the music, which would be much less annoying if the loops were simply longer. Publishers are flooding the market with add-on computer-based materials for the various levels of chemistry. Many constitute little more than a stack of overheads. This is one that may be of sufficient value to warrant the extra cost. A large number of examples are provided for many of the areas covered. Most of the graphical interfaces are clear and easy to manipulate, with the exception of a couple of mechanistic screens that had hard-to-figure-out arrows. Two sections, or modules, are of special note. The first of these is the synthesis challenges, where students must choose reactants, reagents, and reaction conditions for a particular reaction. These synthesis problems are well thought out and can be challenging. It is unfortunate that there are only five of them. The Self-Tests module is also of great practical value, forcing students to work through a variety of topics (200 problems) with limited time allotted per test. The structures are clear and easy to view and include a large number of three-dimensional molecular models that help make the connection between simple line drawings and actual molecules. More feedback information on incorrect answers would be nice, although it is obvious that this can balloon into an unworkable situation if every possible "wrong" answer is considered. The structure summary, which uses a single complicated molecule to review a large range of structural topics, is a good integrated look at bonding, stereochemistry, and conformational analysis. The concentration game is informative, albeit a bit obtuse on a few of the answers! The selection drills, a shooting gallery game with various chemical targets, seems a bit silly, but then if one can learn to recognize all the major reducing agents by snagging butterflies with faux nets than this could be helpful! With its varying levels of difficulty, this set of modules should be accessible even to weaker students and yet will provide a challenge for the more advanced. A great future addition would be an interactive module builder that allows faculty to modify existing questions and add their own. How can one effectively use this program? The relatively low cost does make it accessible for individual students to purchase, perhaps as a "recommended" item for the class. Another very practical option is to purchase 5-10 copies (assuming a class size of around 30-40) and make them available through a common computer laboratory (or an appropriate network site-license arrangement) or for check-out to small groups of students. One drawback is that only about 1/3 of the major topics that fill the year in organic are covered. I have used some of the drills as in-class interactive examples with a projector and laptop. This type of interactive tutorial-quiz-based program is a welcome change from the simple textbook on a CD-ROM approach. Given easy access to computers and an environment that encourages individual and small-group interactions, I believe this program can be a worthwhile aid for students of organic chemistry.

    Full Text Available Introduction: Gastroesophageal reflux disease (GERD is recognized as one of the most common disorders of the upper gastrointestinal tract (GIT. The best choice of management for advanced GERD is laparoscopic surgery. Aim : To compare and evaluate the results of surgical treatment of GERD patients operated on using two different techniques. Material and methods : Between 2001 and 2012, 353 patients (211 female and 142 male, aged 17–76 years (mean 44, underwent laparoscopic antireflux surgery. The study included patients who underwent a Toupet fundoplication or Wroblewski Tadeusz Procedure (WTP. Results: The mean age of the group was 47.77 years (17–80 years. Forty-nine (32.45% patients had severe symptoms, 93 (61.58% had mild symptoms and 9 (5.96% had a single mild but intolerable sign of GERD. Eighty-six (56.95% patients had a Toupet fundoplication and 65 (43.04% had a WTP. The follow-up period was 18–144 months. The average operating time for Toupet fundoplication and the WTP procedure was 164 min (90–300 min and 147 min (90–210 min, respectively. The perioperative mortality rate was 0.66%. The average post-operative hospitalization period was 5.4 days (2–16 post-operative days (POD = Toupet vs. 4.7 days (2–9 POD = WTP. No reoperations were performed. No major surgical complications were identified. Conclusions : Wroblewski Tadeusz Procedure due to a low percentage of post-operative complications, good quality of life of patients and a zero recurrence rate of hiatal hernia should be a method of choice.

    We report on an experimental setup for measurements of dynamic stall for airfoils via the pressure distribution over wind tunnel walls. This measuring technique, hitherto used for lift measurements under static conditions, is also an adequate method for dynamic conditions until stall occurs. A step motor is used, allowing for sinusoidal as well as non-sinusoidal and stochastic pitching to simulate fast fluctuating flow conditions. Measurements with sinusoidal pitching and constant angular velocities were done and show dynamic stall characteristics. Under dynamic stall conditions, maximum lift coefficients were up to 80% higher than the maximum for static lift.

    2016-01-01

    Ce 3+ -doped Gd 2 O 3 -based scintillation glasses are prepared within an air or CO atmosphere. The effects of fluorine, lutetium, barium, and the melting atmosphere on the optical properties, scintillation properties and irradiation hardness are studied. Absorption spectra, luminescence spectra under UV and X-ray excitation, and the X-ray radiation-induced spectra are presented. The results show that the density can be increased by doping with fluorine, lutetium and barium. The luminescence intensity decreases after X-ray irradiation. Because of charge transfer quenching, fluorine and lutetium enhance the UV-excited and X-ray excited luminescence intensity, but barium decreases. Moreover, fluorine and lutetium are advantageous to irradiation hardness while barium is not. In addition, a non-reducing atmosphere provides a higher irradiation hardness than a reducing atmosphere. Fluorine-doped glass is promising to enhance luminescence intensity, promote irradiation hardness, and increase the density.
