    We report on the morphological luminosity functions (LFs) and radial profiles derived for the galaxy population within the rich cluster Abell 868 (z=0.153) based purely on Hubble Space Telescope Imaging in F606W. We recover Schechter functions for early(E/S0)-, mid(Sabc)- and late(Sd/Irr)- type galaxies. The early-, mid- and late- types are all consistent with the recent field morphological LFs based on recent analysis of the Sloan Digital Sky Survey -- Early Data Release (SDSS-EDR; Nakamura et al 2003). From a detailed error analysis, including clustering of the background population, we note that improved statistics can only come from combining data from many clusters. We also examine the luminosity-density and number-density profiles as a function of morphology and draw the following conclusions: (1) The galaxies responsible for the steep faint-end slope are predominantly of late-type morphology, (2) The cluster core is dominated by elliptical galaxies, (3) The core is devoid of late-types systems, (4) The...

Using the eight new times of light minimum determined by the authors together with those collected from literatures, the authors found that the general trend of the observed-calculate ($O$-$C$) curve shows a upward parabolic variation that corresponds to a long-term increase in the orbital period at a rate of $dP/dt=9.38\\times{10^{-7}}day\\cdot year^{-1}$. The continuous increase may be caused by a mass transfer from the less massive component to the more massive one.

    A receiver for SRDs implemented by the 0.35 mum CMOS process is presented. The receiver, together with the ADC, power amplifier (PA), frequency synthesizer and digital baseband has been integrated into a single chip solution. Low cost and low power requirements are met by optimizing the receiver architecture and circuit topology. A simple mixed-signal mode I/Q imbalance calibration circuit is proposed to enhance the IRR (image rejection ratio) so as to raise the BER. From a single 3 V power supply, the receiver consumes 5.9 mA. The measurement result shows that the receiver achieves reference sensitivity of s-60 dBm and a control gain of 60 dB. The S{sub 11} reaches -20 dB at 433 MHz and -10 dB at 868 MHz without off-chip impedance match network. The die area is only 2 mm{sup 2} including the bias circuit.

  6. Long-term outcomes of intensity-modulated radiotherapy for 868 patients with nasopharyngeal carcinoma: An analysis of survival and treatment toxicities

    International Nuclear Information System (INIS)

    Background and purpose: To evaluate the long-term survival outcomes and toxicity of NPC patients treated with intensity-modulated radiotherapy (IMRT). Materials and methods: From May 2001 to October 2008, 868 non-metastatic NPC patients treated by IMRT were analyzed retrospectively. The Radiation Therapy Oncology Group (RTOG) criteria were used to assess toxicity. Results: With a median follow-up of 50 months (range, 5–115 months), the 5-year estimated disease specific survival (DSS), local recurrence-free survival (LRFS), regional recurrence-free survival (RRFS) and distant metastasis-free survival (DMFS) were 84.7%, 91.8%, 96.4% and 84.6%, respectively. Of the 868 patients, 186 (21.3%) developed failure after treatment. Distant metastasis was the major failure pattern after treatment. The 5-year OS rate in patients with stage I, II, III, and IVa–b were 100.0%, 94.3%, 83.6%, and 70.5%, respectively. The 5-year LRFS rate in patients with stage T1, T2, T3, and T4 disease were 100.0%, 96.0%, 90.4%, and 83.3%, respectively (χ2 = 26.32, P < 0.001). The 5-year DMFS for N0, N1, N2, and N3 patients were 96.1%, 85.6%, 73.7%, and 62.1%, respectively (χ2 = 65.54, P < 0.001). Concurrent chemotherapy failed to improve survival rates for patients with advanced locoregional disease. The most common acute toxicities were mainly in grade 1 or 2. Compared with IMRT alone, IMRT plus concurrent chemotherapy increased the severity of acute toxicities. The incidence of brain radiation damage was relatively high (5.5%, 48/868 cases), and was not observed in patients with stage T1–2. Conclusion: IMRT for NPC yielded excellent survival outcomes, and distant metastasis was the most commonly seen failure pattern after treatment. The role of concurrent chemotherapy for advanced locoregional stage NPC patients needs to be further investigated. Treatment-related toxicities were well tolerable. However, the incidence of brain radiation damage was relatively high, especially for patients

    A low power frequency synthesizer suited for wireless sensor network transceiver in 780 (China)/868( Europe)/915 ( USA) MHz frequency bands is proposed. The current reusing technique is adopted to make the voltage controlled oscillator (VCO) and divider share a common bias current so to cut down the power budget. A novel lock detector with programmable locked-detecting thresholds is integrated in frequency synthesizer to detect the locked time. Frequency synthesizer was fabricated in 0.18 u,m CMOS (complementary metal oxide semiconductor) technology and the measurement was carried out. Test results show that the frequency rang of synthesizer is 770 - 930 MHz; when the output frequency is 868 MHz, the phase noise is - 87 dBc/Hz in band, with - 98 dBc/Hz @ 100 kHz and - 124 dBc/Hz@ 1 MHz; the measured locked time is 91 -112 u,s with different locked-detecting thresholds; the total current of synthesizer is 3.9 mA under 1.8 V supply.%提出了一种适用于780(中国)/868(欧洲)/915(美国)MHz频段无线传感器网络收发机的低功耗频率综合器,采用电流复用技术使压控振荡器(VCo)和分频器共享偏置电流从而降低了功耗.集成了新型锁定检测门限可编程的锁定检测器用于锁相时间指示.频率综合器采用0.18 μm CMOS工艺进行验证和测试.测试结果显示:频率覆盖范围约为770 ~930MHz;输出信号频率为868 MHz时带内相位噪声为- 87 dBc/Hz,频偏100 kHz和1 MHz处相位噪声分别为-98和- 124 dBc/Hz;在不同锁定检测门限下测得锁定时间为91~112 μs;在工作电压为1.8V时,频率综合器工作电流约为3.9mA.

  8. Indoor radio channel modeling and mitigation of fading effects using linear and circular polarized antennas in combination for smart home system at 868 MHz

    2014-11-01

    The markets for smart home products and services are expected to grow over the next years, driven by the increasing demands of homeowners considering energy monitoring, management, environmental controls and security. Many of these new systems will be installed in existing homes and offices and therefore using radio based systems for cost reduction. A drawback of radio based systems in indoor environments are fading effects which lead to a high variance of the received signal strength and thereby to a difficult predictability of the encountered path loss of the various communication links. For that reason it is necessary to derive a statistical path loss model which can be used to plan a reliable and cost effective radio network. This paper presents the results of a measurement campaign, which was performed in six buildings to deduce realistic radio channel models for a high variety of indoor radio propagation scenarios in the short range devices (SRD) band at 868 MHz. Furthermore, a potential concept to reduce the variance of the received signal strength using a circular polarized (CP) patch antenna in combination with a linear polarized antenna in an one-to-one communication link is presented.

    International Nuclear Information System (INIS)

    This report describes the environmental surveillance program at the Wayne Interim Storage Site (WISS) and provides the results for 1992. The fenced, site, 32 km (20 mi) northwest of Newark, New Jersey, was used between 1948 and 1971 for commercial processing of monazite sand to separate natural radioisotopes - predominantly thorium. Environmental surveillance of WISS began in 1984 in accordance with Department of Energy (DOE) Order 5400.1 when Congress added the site to DOE's Formerly Utilized Sites Remedial Action Program (FUSRAP). The environmental surveillance program at WISS includes sampling networks for radon and thoron in air; external gamma radiation exposure; radium-226, radium-228, thorium-230, thorium-232, total uranium, and several chemicals in surface water and sediment; and total uranium, radium-226, radium-228, thorium-230, thorium-232, and organic and inorganic chemicals in groundwater. Monitoring results are compared with applicable Environmental Protection Agency (EPA) and state standards, DOE derived concentration guides (DCGs), dose limits, and other DOE requirements. This monitoring program assists in fulfilling the DOE policy of measuring and monitoring effluents from DOE activities and calculating hypothetical doses. Results for environmental surveillance in 1992 show that the concentrations of all radioactive and most chemical contaminants were below applicable standards

  6. Interaction between smoking and functional polymorphism in the TGFB1 gene is associated with ischaemic heart disease and myocardial infarction in patients with rheumatoid arthritis: a cross-sectional study

    Science.gov (United States)

    2012-01-01

    Introduction Transforming growth factor-beta1 (TGF-beta1) is a pleiotropic cytokine that plays important roles in immunity and inflammation. Some studies have suggested that polymorphism in the TGFB1 gene is associated with heart disease in the general population. The purpose of the present study was to determine whether common single-nucleotide polymorphisms (SNP) in the TGFB1 gene are associated with ischaemic heart disease (IHD) and/or myocardial infarction (MI) in patients with rheumatoid arthritis (RA), and to investigate the influence of smoking on any association. Methods PCR-based assays were used to determine the genotypes of TGFB1 SNPs including TGFB1-509 C/T (rs1800469, in the promoter region), +868 T/C (rs1800470, in exon 1) and +913 G/C (rs1800471, in exon 1) in 414 subjects with established RA. Genotyping for the +868 SNP was also carried out on a second study population of RA patients (n = 259) with early disease. Serum levels of TGF-beta1 were measured using a commercial ELISA kit. Smoking history and IHD/MI status were obtained on each patient. Associations with IHD/MI were assessed using contingency tables and logistic regression analyses. Results The heterozygous genotype of TGFB+868 was associated with an increased risk of IHD (OR 2.14, 95% CI 1.30 - 3.55) and MI (OR 2.42, 95% CI 1.30-4.50), compared to the homozygous genotypes combined. Smoking was an independent risk for IHD and MI, and evidence of interaction between smoking and TGFB+868 was found. Multivariate analyses indicated that the strongest associations with IHD and MI were due to the combined effect of the TGFB1+868 TC genotype and smoking (OR 2.75, 95% CI 1.59-4.75; and OR 2.58 95% CI 1.33-4.99, respectively), independent of other cardiovascular risk factors. The association of the +868 TC genotype and evidence of +868 TC-smoking interaction with IHD were replicated in a second population of RA patients with early disease. Serum TGF-beta1 levels were not associated with TGFB1

    Full Text Available ABSTRACT Objective To describe a unique operative strategy, instead the classical pterional approach, and to analyses it safety and effectiveness for removal of anterior cranial fossa meningiomas. Method We identify 38 patients with tuberculum sellae and olphactory groove meningiomas operated between 1986 and 2013. Medical charts, operative reports, imaging studies and clinical follow-up evaluations were reviewed and analyzed retrospectively. The pterional craniotomy is extended toward the frontal bone providing access through the subfrontal route, besides the usual anterolateral view provided by the classical pterional approach. Results Surgical mortality occurred in one patient (2.6%. Gross total resection was achieved in 27 patients (86.8%. Median time of follow-up was 69.4 months. Conclusion The extended pterional approach allows excellent results. Total removal of meningiomas of the anterior cranial fossa was obtained in 86.8 % of patients, with low morbidity and mortality.

    Although many studies have found psychological depression associated with higher circulating levels of C-reactive protein (CRP), not all findings are consistent. Since DNA sequence variation in the CRP gene has also been shown to predict plasma CRP levels, we hypothesized that plasma CRP may covary with depressive symptomatology as a function of allelic variation in the CRP gene. We tested this hypothesis in 868 healthy community volunteers of European ancestry. Depressive symptomatology was ...

    Qinchuan is a red or yellow draft and beef breed in China. In order to identify a predictor of carcass traits on the basis of associations between carcass traits and gene polymorphism, variation in the bovine chemerin gene was investigated using PCR-single-strand conformational polymorphism and DNA sequencing. An SNP of A868G located in exon 2 of the Bos taurus chemerin gene was detected in 716 samples of six breeds (Jiaxian red, Luxi, Nan yang, Qinchuan, Simmental and Luxi crossbred steers, and Xia'nan), all in China, and three genotypes (AA, AG and GG) were found. Based on the χ(2) test, the AA/AG/GG genotype frequencies of all six breeds were found to be in Hardy-Weinberg equilibrium. A possible association of A868G with some carcass traits was investigated in 106 Qinchuan cattle. Animals with the AG genotype were found to have significantly lower mean loin eye area and meat tenderness compared to those with the AA and GG genotypes. However, there was no significant association between any individual haplotype and backfat thickness, water holding capacity or marbling score. We suggest that A868G could be used as a molecular marker in marker-assisted selection for carcass traits. PMID:22095607

  8. Twisted epithelial-to-mesenchymal transition promotes progression of surviving bladder cancer T24 cells with hTERT-dysfunction.

    Directory of Open Access Journals (Sweden)

    Yan Xue

    Full Text Available BACKGROUND: Human cancer cells maintain telomeres to protect cells from senescence through telomerase activity (TA or alternative lengthening of telomeres (ALT in different cell types. Moreover, cellular senescence can be bypassed by Epithelial-to-mesenchymal transition (EMT during cancer progression in diverse solid tumors. However, it has not been elucidated the characteristics of telomere maintenance and progression ability after long-term culture in bladder cancer T24 cells with hTERT dysfunction. METHODOLOGY/PRINCIPAL FINDINGS: In this study, by using a dominant negative mutant human telomerase reverse transcriptase (hTERT vector to inhibit TA in bladder cancer T24 cells, we observed the appearance of long phenotype of telomere length and the ALT-associated PML body (APB complex after the 27(th passage, indicating the occurrence of ALT-like pathway in surviving T24/DN868A cells with telomerase inhibition. Meanwhile, telomerase inhibition resulted in significant EMT as shown by change in cellular morphology concomitant with variation of EMT markers. Consistently, the surviving T24/DN868A cells showed increased progression ability in vitro and in vivo. In addition, we found Twist was activated to mediate EMT in surviving T24/DN868A samples. CONCLUSIONS/SIGNIFICANCE: Taken together, our findings indicate that bladder cancer T24 cells may undergo the telomerase-to-ALT-like conversion and promote cancer progression at advanced stages through promoting EMT, thus providing novel possible insight into the mechanism of resistance to telomerase inhibitors in cancer treatment.

    This paper presents the first empirical assessment of the causal relationship between social capital and health in Italy. The analysis draws on the 2000 wave of the Multipurpose Survey on Household conducted by the Italian Institute of Statistics on a representative sample of the population (n=46,868). Our measure of social capital is the frequency of meetings with friends. Based on IV and bivariate probit estimates, we find that individuals who meet friends every day or more time times a week are approximately 11-16% more likely to report good health. PMID:25805101

    The idea of collecting solar electromagnetic radiation with antenna-rectifier (rectenna) structures was proposed three decades ago but has not yet been achieved. The idea has been promoted as having potential to achieve efficiency approaching 100% but thermodynamic considerations imply a lower limit of 85.4% for a non-frequency-selective rectenna and 86.8% for one with infinite selectivity, assuming maximal concentration in each case. This paper reviews the history and technical context of solar rectennas and discusses the major issues: thermodynamic efficiency limits, rectifier operation at optical frequencies, harmonics production and electrical noise.

  14. Antioxidant Activity and the relationship with Panholic Composition in some Egyptian Pomegranate Cultivars

    International Nuclear Information System (INIS)

    Pomegranate fruit is an important source of potentially healthy bioactive compounds. Changes in total phenolic content, phenolic compounds and anti radical activity in juice and peel extracts of pomegranate fruit of five cultivars were studied. Total phenolic content (TPC) varied between 1598.96 and 2315.10 mg gallic acid L-1 for pulp juice while TPC ranged from 8.68 to 15.46 mg/g in peel extract. All cultivars juice and peel extracts undertaken had a high capacity while TPC changed from 8.68 to 15.94 mg gallic acid scavenge 1,1-diphenyl-2-picrylhydrazyl (DPPH0) and β- carotene assays Increasing the concentration of either pomegranate juice (PJ) or peel extract increased (P < 0.05) the radical scavenging activity, however anti radical activity of peel extracts was higher than juice one. A good correlation between phenolic content and the radical scavenging activities was observed higher in peel extract than fruit juice. According to the results of high performance liquid chromatography (HPLC), the gallic acids, chlorogenic acid and caffeic were the predominant phenolic compounds of the pomegranate cultivars. We concluded that pomegranate peel extract and juice appeared to have more potential as a health supplement rich in natural antioxidants than the pulp extract and merits and need further intensive study.

  15. Rheological Properties of Hydrophobically Associating Polyacrylamide Solution

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    A temperature-resistant, salt-tolerant polyacrylamide, hydrophobically associating polymer (HAP), was synthesized in the State Key Laboratory of Heavy Oil Processing. The rheological behavior of HAP solution was investigated by means of flow experiments in porous media and by using a HAAKE RS600 rheometer. The results of Nuclepore membrane filtration showed that filtration time increased sharply when the critical association concentration was reached. Shear rate had a greater impact on viscosity and shear stress with increasing HAP concentration. The HAP solution with a concentration of 100 mg/L (salinity 32,868 mg/L) exhibited negative thixotropy. However, at the same salinity the HAP solution showed thixotropy and its viscosity became greater when the polymer concentration increased to 1,500 mg/L.The flow experiments in cemented core samples indicated that the resistance factor and residual resistance factor of the HAP solution were 31.8 and 12 when polymer concentration and salinity were 1,500 mg/L, 32,868 mg/L at 85℃ respectively,which is favorable for flooding application. Such factors of partially hydrolyzed polyacrylamide 3530S were merely 3.14 and 1.71, so it could not be applied to polymer flooding in the oilfield with high temperature and high salinity.

    Full Text Available Robust real-time hand detection and tracking in video sequences would enable many applications in areas as diverse ashuman-computer interaction, robotics, security and surveillance, and sign language-based systems. In this paper, we introducea new approach for detecting human hands that works on single, cluttered, low-resolution images. Our prototype system, whichis primarily intended for security applications in which the images are noisy and low-resolution, is able to detect hands as smallas 2424 pixels in cluttered scenes. The system uses grayscale appearance information to classify image sub-windows as eithercontaining or not containing a human hand very rapidly at the cost of a high false positive rate. To improve on the false positiverate of the main classifier without affecting its detection rate, we introduce a post-processor system that utilizes the geometricproperties of skin color blobs. When we test our detector on a test image set containing 106 hands, 92 of those hands aredetected (86.8% detection rate, with an average false positive rate of 1.19 false positive detections per image. The rapiddetection speed, the high detection rate of 86.8%, and the low false positive rate together ensure that our system is useable asthe main detector in a diverse variety of applications requiring robust hand detection and tracking in low-resolution, clutteredscenes.

    2004-01-01

    Full Text Available Einleitung: Bei Patienten mit Aortenklappenstenose wird häufig neben einer echokardiographischen Untersuchung eine retrograde Katheterisierung der Aortenklappe zur Beurteilung des Stenoseschweregrades vorgenommen. Hierbei wurde in rezenten Publikationen das vermehrte Auftreten von zerebralen Embolien berichtet. Methodik: Wir untersuchten die Häufigkeit von neurologischen Komplikationen in einer retrospektiven Analyse von 325 Patienten, bei denen im Zeitraum von Jänner 2000 bis Dezember 2003 aufgrund einer Aortenklappenstenose eine Koronarangiographie mit retrograder Katheterisierung der Aortenklappe durchgeführt worden war. Als Vergleichsgruppe diente ein Patientenkollektiv von 1.868 konsekutiven Patienten mit koronarer Herzerkrankung ohne Aortenklappenstenose, bei denen ebenfalls eine Koronarangiographie mit Laevogramm durchgeführt worden war. Ergebnisse: Bei keinem der Patienten mit Aortenklappenstenose traten innerhalb von 72 Stunden nach retrograder Katheterisierung der Aortenklappe klinisch faßbare neurologische Komplikationen (zerebraler Insult oder transitorisch ischämische Attacke auf. In der Vergleichsgruppe kam es bei 2 von 1.868 Patienten innerhalb des oben genannten Zeitraumes zu neurologischen Komplikationen. Schlußfolgerung: In unserer retrospektiven Analyse war bei Patienten mit Aortenklappenstenose und durchgeführter retrograder Katheterisierung der Aortenklappe kein höheres Risiko für das Auftreten von klinisch manifesten neurologischen Ereignissen zu beobachten.

  20. Vortex-pair excitation near the superconducting transition of Bi2Sr2CaCu2O8 crystals

    International Nuclear Information System (INIS)

    The dissipation observed at the superconducting transition of the high-T/sub c/ superconductor Bi2Sr2CaCu2O8 is explained quantitatively by the Kosterlitz-Thouless theory of vortex-antivortex pair excitations within the CuO2 planes. This conclusion is drawn from the observation of an exponential square-root singularity in the resistivity and a power-law dependence of the resistivity on magnetic field. The Kosterlitz-Thouless phase transition (T/sub c/ = 84.7 K) is at the rho = 0 point, and the mean-field Ginzburg-Landau tansition (T/sub c/0 = 86.8 K) is at∼25% of the normal-state resistivity

    The microwave properties of a crystalline sapphire dielectric whispering gallery mode resonator have been measured at very low excitation strength (E/hf=1) and low temperatures (T = 30 mK). The measurements were sensitive enough to observe saturation due to a highly detuned electron spin resonance, which limited the loss tangent of the material to about 2e-8 measured at 13.868 and 13.259 GHz. Small power dependent frequency shifts were also measured which correspond to an added magnetic susceptibility of order 1e-9. This work shows that quantum limited microwave resonators with Q-factors > 1e8 are possible with the implementation of a sapphire whispering gallery mode system.

    Full Text Available Analyzing 167 non-processed seed samples of wheat, it was found that 145 samples (86.8 % were contaminated with Tilletia species, while 22 (13.2 % samples were not contaminated. By using rep-PCR fingerprinting technique, it was found that DNA isolates of T. tritici originated from Serbian wheat samples had 80 % similarity with positive control for T. tritici. One isolate shared similarity of 60% with T. tritici, T. controversa and T. laevis. It was supposed that this isolate belongs to T. bromi. Isolate of T. laevis shared a similarity of 70 % with isolates of T. tritici and T. controversa, while T. walkeri was more than 10 % similar with T. tritici, T. controversa and T. laevis. Although T. controversa and T. tritici had high percent of genetic similarity, they were clustered separately. Our results suggest that rep-PCR fingerprinting could be a useful tool for monitoring presence of morphologically similar Tilletia species in wheat production areas.

    OBJECTIVE: The adipocytokines, leptin, adiponectin, and interleukin-6, which stimulate liver C-reactive protein (CRP) production, are regarded as potential candidate intermediates between adipose tissue and overweight-induced hypertension. METHODS: We examined the associations between leptin......, adiponectin, and CRP levels with both prevalent and 5-year incident hypertension (IHT) in a general population of Danish adults (n = 5,868, 51.3% women, mean age 45.8 ± 7.9 years). RESULTS: We recorded 2195 prevalent and 379 incident cases of hypertension. In models including leptin, CRP, adiponectin, sex...... fully adjusted model. The population attributable risk estimate of IHT owing to overweight was 31%. CONCLUSION: Leptin, but not adiponectin or CRP, may play a mediating role in overweight-induced hypertension. However, as BMI was a strong independent predictor of hypertension, other factors than leptin...

    1997-02-06

    A nuclear criticality safety analysis has been performed to increase the approved plutonium mass limit for cans stored in Vault {number_sign}4 cubicles at PFP. The cubicles were approved to hold up to 2.5 kg of plutonium on each pedestal. The purpose of this CSER is to accommodate the storage of 4.4 kg of plutonium in PuO, (5.0 kg PuO,) in Vault {number_sign}4 cubicles. The highest k{sub eff} calculated for all possible scenarios is 0.868 + 0.003 when every other cubicle is left vacant, which is well below the criticality safety limit of k{sub eff}=0.935. Consequently, an increase of plutonium mass to 4.4 kg per can is within acceptable safety limits for this configuration.

    Odum, O.

    1995-01-01

    Full Text Available A survey of the fish farms in the southern part of Delta State, Nigeria was carried out to determine the significant changes that have taken place since a similar study was carried out 5 years earlier. The results show that fish farming has attained a greater commercial status. Between 1989 and 1994, the projected total area under cultivation rose by 86.8 % to 564.4 ha while average production increased significantly to 2, 315.16 kg/ha/yr from 913.07 kg/ha/yr. This increased yield is attributed to better management of the farms. However, many problems are still slowing down the growth and development of aquaculture in the area mainly because many of the measure initiated by government over the years have been largely unsuccessful.

    Van Dusen, Ben; Roualdes, Edward

    2016-01-01

    This study investigates how Learning Assistants (LAs) and related course features are associated with student learning inequities in introductory university physics courses. Over 2,868 physics student paired pre- and post-test scores on concept inventories from 67 classes in 16 LA Alliance member institutions were collected. The concept inventories included the Force Concept Inventory, Force and Motion Conceptual Evaluation, and the Conceptual Survey of Electricity and Magnetism. Our analyses developed a multiple linear regression model that examines the impact of student (e.g. gender and race) and course level variables (e.g. presence of LAs and Concept Inventory used) on student learning outcomes (Cohen's d effect size) across classroom contexts. The presence of LAs was found to remove or invert the traditional performance gaps between majority and underrepresented minority students. Significant differences in student performance were also found across the concept inventories.

    2010-01-01

    The most frequent infectious diseases in humans - and those with the highest potential for rapid pandemic spread - are usually transmitted via droplets during close proximity interactions (CPIs). Despite the importance of this transmission route, very little is known about the dynamic patterns of CPIs. Using wireless sensor network technology, we obtained high-resolution data of CPIs during a typical day at an American high school, permitting the reconstruction of the social network relevant for infectious disease transmission. At a 94% coverage, we collected 762,868 CPIs at a maximal distance of 3 meters among 788 individuals. The data revealed a high density network with typical small world properties and a relatively homogenous distribution of both interaction time and interaction partners among subjects. Computer simulations of the spread of an influenza-like disease on the weighted contact graph are in good agreement with absentee data during the most recent influenza season. Analysis of targeted immuniz...

    This communication demonstrates the feasibility of the gel-clot method for the analysis of bacterial endotoxins in water extracts of perfluorocarbon which is a water insoluble liquid medical device. Perfluorocarbon (10 mL) was shaken with 10mL water for 15 min at 2000 r/min and the endotoxin present was extracted to the aqueous phase without interference inhibition/enhancement of the product and the recovery of endotoxin added to perfluorocarbon was determined. A validation study confirmed that endotoxins presented in perfluorocarbon pass over into the aqueous phase at concentrations of 20, 10 and 5 EU/mL with recoveries from 86.8% to 96.8%. Therefore, the gel-clot test is suitable for detecting bacterial endotoxins in perfluorocarbon which is a water insoluble medical device.

    The crystalline silicates features are mainly reflected in infrared bands. The Spitzer Infrared Spectrograph (IRS) collected numerous spectra of various objects and provided a big database to investigate crystalline silicates in a wide range of astronomical environments. We apply the manifold ranking algorithm to perform a systematic search for the spectra with crystalline silicates features in the Spitzer IRS Enhanced Products available. In total, 868 spectra of 790 sources are found to show the features of crystalline silicate. These objects are cross-matched with the SIMBAD database as well as with the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST)/DR2. The average spectrum of young stellar objects show a variety of features dominated either by forsterite or enstatite or neither, while the average spectrum of evolved objects consistently present dominant features of forsterite in AGB, OH/IR, post-AGB and planetary nebulae. They are identified optically as early-type stars, evolved stars...

    2002-01-01

    Telomerase activity was detected with both telomeric repeat amplification protocol (TRAP) - silver stain and polymerase chain reaction (PCR) - enzyme linked immuno - sorbent assay (ELISA). We have studied the telomerase activity in the 68 gastric tumors and their neighboring tissues,25 gastric ulcer, and 3 tumor cell colonies. The positive rate of telomerase activity in gastric tumors was 86.8% (59/68) and which was obviously higher than 7.3% (5/68) in the normal tissues adjacent to the tumors and 4% (1/25) in gastric ulcer. The telomerase activity was 100% (3/3) in the tumor colonies. It allowed to be seen that higher telomerase activity was associated with the origin and development of the gastric tumor. We believe that telomerase activity may be a useful clinical diagnostic marker for the gastric tumor.

    The present study has found that during the integrated processing after the diamond smoothing, in the surface-hardened sample a cold-worked layer 0.01 ... 0.02 mm in thickness, the microhardness value of which reaches 868 HV, is formed. The intensity of compressive stresses on the part surface increases to στ = -678 MPa. The analysis of the experimental data has shown the relationship between the parameter Ra and the processing modes that can be used during diamond smoothing, based on the high performance and the desired surface roughness. It has been found that the minimum value of roughness Ra = 0.18±0.08 μm is reliably achieved by smoothing processing when the smoothing force Py ranges from 100 N to 150 N.

    The RSJ model of the Josephson junction in the presence of a microwave field is studied using an analog computer, with special attention to the behavior of this system near or at the critical line, where the set of substeps forms a complete devil's staircase on the I-V characteristic. A value of fractal dimension D = 0.868 +/- 0.002 is determined from 240 substeps between the winding numbers W = 0 and W = 1. Four values of decay constants are determined. The results agree very well with the prediction obtained from the one-dimensional circle map. A self-similarity graph is shown confirming that the staircase is very near the critical line. Results confirm the universal and global character of D and decay constants on the critical line, as was suggested by Jensen et al

    Full Text Available Previous studies have demonstrated that invertebrate immune and neural tissues contain mammalian-like cytokines, which activate specific cellular functions. Therefore, it was of interest to attempt to identify these molecules via Applied Biosystems Human Genome Survey Arrays. The array was used to analyze the transcriptional profiles of Mytilus edulis RNA samples. The Applied Biosystems Human Genome Survey Array contains 31,700 60-mer oligonucleotides probes representing a set of 27, 868 individual human genes and more than 1,000 control probes. We show interleukin-like and tumor necrosis factor-like genes among other cytokine-like genes significantly expressed in this invertebrate tissue with a signal to noise value greater than 2. In morphine treated tissue additional cytokine genes were expressed. These cytokine-like genes are directly related to previously discovered molecules in invertebrates, suggesting that they first appeared earlier in evolution.

    The objective of this study was to estimate the incidence of cancer and human papillomavirus (HPV)-related cancers and the risk of death (by cancer status) among people living with AIDS (PLWA) in Puerto Rico. We used data from the Puerto Rico AIDS Surveillance Program and Central Cancer Registry (1985-2005). Cancers with highest incidence were cervix (299.6/100,000) for women and oral cavity/oropharynx for men (150.0/100,000); the greatest excess of cancer incidence for men (standardized incidence ratio, 86.8) and women (standardized incidence ratio, 52.8) was for anal cancer. PLWA who developed a cancer had decreased survival and increased risk of death compared with those who did not have cancer. Cancer control strategies for PLWA will be essential for improving their disease survival. PMID:24831284

    Full Text Available The nutritive and antinutritive composition of cassava roots (raw and boiled was investigated. The proximate composition of raw and boiled cassava tubers was not significantly different (P> 0.05, except in moisture, fat, carbohydrate and Energy value. High levels of the antinutrients in raw cassava tubers (20.56mg/100g Tannins; 1,16mg/100g oxalate and 3.36mg/100g phytate make them unsafe and unsuitable for human consumption except after processing. Mineral contents of cassava tubers were not affected significantly by boiling except in Iron. Calcium was the most abundant mineral present (0.33% and 0.26% for raw and boiled cassava roots and the low Ca/P ratio of 6.19 in boiled cassava roots will facilitate calcinations of calcium more than the raw cassava roots with a Ca/P ratio of 8.68.

    Specimens of V-4Cr-4Ti alloy were heated at 1273 K in vacuum, and the influence of this heat treatment on H 2 absorption was examined at temperatures from 523 to 1023 K under the presence of water vapor of 10 -5 Pa. The rate of H 2 absorption was significantly reduced by the heat treatment in the temperature range examined. Such reduction in the absorption rate was ascribed to the surface segregation of Ti and increase in surface oxygen coverage caused by preferential oxidation of segregating Ti by water vapor. Comparison with data reported by other researchers [J. Nucl. Mater. 233-237 (1996) 376; Fusion Technol. 34 (1998) 868; J. Nucl. Mater. 233-237 (1996) 510] indicated the strong barrier effect of Ti oxide against hydrogen ingress.

    The present work reports on magnetically induced optical activity (such as Faraday rotation and linear dichroism) of pristine and gamma-irradiated gadolinium oxide (Gd{sub 2}O{sub 3}) nanoparticle-based ferrofluids. The ferrofluids were produced by dispersing N-cetyl-N,N,N-trimethyl ammonium bromide (CTAB)-coated {approx}9-nm-sized Gd{sub 2}O{sub 3} particles in a carrier fluid of ethanol. The ferrofluids were then irradiated with 1.25 MeV energetic gamma rays (dose: 868 Gy and 2.635 kGy). Irradiation-led formation of a number of point defects was revealed through high resolution electron microscopy. The interaction of light with the ionized point defects is believed to have caused substantial improvement in the magneto-optic response of irradiated magnetic fluids.

    We report nano Zinc Oxide (ZnO) synthesized by sol-gel method possessing the crystallite size which varies from 25.17 nm to 47.27 nm. The Scanning electron microscope (SEM) image confirms the uniform distribution of nanograins with high porosity. The Energy dispersion X-ray (EDAX) spectrum gives the atomic composition of Zn and O in ZnO powders and confirms the formation of nano ZnO particles. These factors reveals that Nano ZnO based gas sensors are highly sensitive to Ammonia gas (NH3) at room temperature, indicating the maximum response 86.8% at 800 ppm with fast response time and recovery time of 36 sec and 23 sec respectively.

    We study the role of the environment on galaxy evolution using a sample of 868 galaxies in the Virgo cluster and in its surrounding regions selected from the GUViCS Survey with the purpose of understanding the origin of the red sequence in dense environments. We collected multifrequency data covering the whole electromagnetic spectrum for most of the galaxies. We identify the different dynamical substructures composing the Virgo cluster and we calculate the local density of galaxies using different methods. We then study the distribution of galaxies belonging to the red sequence, the green valley, and the blue cloud within the different cluster substructures. Our analysis indicates that all the most massive galaxies are slow rotators and are the dominant galaxies of the different cluster substructures generally associated with a diffuse X-ray emission. They are probably the result of major merging events that occurred at early epochs. Slow rotators of lower stellar mass are also preferentially located within ...

  9. Use of IQRF technology for detection of construction inclination

    Science.gov (United States)

    Martin, Pies; Radovan, Hajovsky

    2016-06-01

    This paper deals with the application of wireless measurement of inclination of objects located at mining dumps. Measurement of inclination uses a set of sensors including a gyroscope, an accelerometer and a magnetometer. Measured data is processed by AHRS algorithm that, once applied, allows getting more precise information on rotation of the object in the area compared to unprocessed data from accelerometer or gyroscope. Measurement chain consists of two parts. The first one is a wireless module reading the data from particular sensors via I2C bus and sends it consequently to a computer that performs evaluation and visualization of inclination. Communication among particular devices is ensured by IQRF technology working within ISM band of 868MHz. Application of this approach for measurement of inclination is a reasonable choice in case of measurement of inclination by inclinometers.

    Full Text Available Globally quoted and unquestioningly accepted, the State of the Food Insecurity in the world report 2012, has made significant reduction in the numbers of hungry globally at 868 million. In case of India it has made significant upward revision of hunger prevalence in 1990-92 and significant downward revision for 2010 resulting in 34.9% estimated hunger decline. In the midst of claims of robust methodological revisions, its calculations and assumptions set a dangerous precedence for the policy-makers and planners of the reluctant country governments and worst for the hungry of the world. This paper discusses the SOFI 2012, critiques the declining hunger numbers in SOFI 2012 and produces alternate data sets including independent surveys of Government of India, to counter the reduction claims. It also makes a case for greater public dialogue and engagement in such reports, their methods, metrics and numbers.

    The composites of carbon nanotube wrapped Si particles (CNTWS) were synthesized in situ by using the catalytic chemical vapor deposition (CCVD) method. In this process, carbon nanotubes were produced in situ to wrap Si by the catalysis action of nascent Cu* under an acetylene atmosphere at a relatively low temperature of 400 °C, in which nascent Cu* was created by the reaction between Si particles and CuCl synchronously. The weight ratio of Si/C in CNTWS is 0.76/0.24. As anode materials for lithium ion batteries, the CNTWS composites exhibit a reversible discharge capacity of 1031.1 mA h g(-1) at 1.8 A g(-1) after 500 cycles, and 868.2 mA h g(-1) at 10.0 A g(-1). The high electrochemical performance of CNTWS composites is associated with the in situ formed carbon nanotubes. PMID:26875542

    Acinetobacter baumannii, a strictly aerobic, non-fermentative, Gram-negative coccobacillary rod-shaped bacterium, is an opportunistic pathogen in humans. We recently isolated a multidrug-resistant A. baumannii strain KBN10P02143 from the pus sample drawn from a surgical patient in South Korea. We report the complete genome of this strain, which consists of 4,139,396 bp (G + C content, 39.08%) with 3,868 protein-coding genes, 73 tRNAs and six rRNA operons. Identification of the genes related to multidrug resistance from this genome and the discovery of a novel conjugative plasmid will increase our understanding of the pathogenicity associated with this species.

    Several studies have investigated the accuracy of naked eye visual inspection with acetic acid (VIA) in the early detection of cervical neoplasia. It is not clear whether low-level (2-4x) magnification (VIAM) can improve the sensitivity and specificity of VIA. The accuracy of both VIA and VIAM, provided by independent health workers, were evaluated in three cross-sectional studies involving 18,675 women aged 25-65 years in Kolkata and Mumbai in India. All screened women were investigated with colposcopy and biopsies were obtained based on colposcopy findings. The final disease status was based on the reference standard of histology (if biopsies had been taken) or colposcopy. Data from the studies were pooled to calculate the test characteristics for the detection of high-grade squamous intraepithelial lesions (HSIL). 14.1% and 14.2% were positive on testing with VIA and VIAM respectively. Two hundred twenty-nine were diagnosed with HSIL and 68 with invasive cancer. The pooled sensitivity, specificity, positive and negative predictive values for VIA in detecting high-grade squamous intraepithelial lesions (HSIL) were 60.3% (95% CI: 53.6-66.7), 86.8% (95% CI: 86.3-87.3), 5.9% (95% CI: 5.0-7.0), and 99.4% (95% CI: 99.2-99.5), respectively. The values were 64.2% (95% CI: 57.6-70.4), 86.8% (95% CI: 86.2-87.3), 6.3% (95% CI: 5.3-7.3) and 99.4% (95% CI: 99.3-99.6), respectively, for VIAM. Low-level magnification did not improve the test performance of naked eye visualization of acetic acid impregnated uterine cervix. PMID:15542259

    Thixoforming investigations have been developed primarily for the manufacturing of bulk components, and the current knowledge is very limited with respect to the fabrication of thin cross sections of alloys. We studied the effectiveness of thixoforming process for the fabrication of A356 aluminum alloy bipolar plates with microchannels on both sides. Feedstock semisolid slurries, with different solid contents of ~55, 50, and 45 pct, were prepared at 858 K, 863 K, and 868 K (585 °C, 590 °C, and 595 °C), respectively, and were used to thixoform 1.20-mm-thick bipolar thin plates. The microstructures of the thixoformed thin plates consisted of (i) large primary α-Al globular grains, (ii) a quenched liquid phase, and (iii) fine secondary α-Al particles. The fraction and size of the primary α-Al globular grains decreased, and the primary α-Al globular grains became more spherical with the increasing thixoforming temperature. It seemed that these changes in the microstructural features led to the reduction in the agglomeration and interaction among the primary α-Al globular grains surrounded by the liquid matrix during thixoforming. This enabled the semisolid slurry to effectively flow and fill in the sharp corners (such as the microchannels) of the die cavity at higher thixoforming temperatures. The thin plates thixoformed at 868 K (595 °C), consequently, exhibited the highest dimensional stability and the fewest internal defects. The liquid matrix surrounding the primary α-Al grains solidified inside the die cavity after thixoforming. Either the liquid phase was instantly quenched or fine secondary α-Al particles were formed inside the die cavity. The fraction and size of the latter increased with increasing thixoforming temperature. The surface hardness of the thixoformed plates was measured, and the hardness values were correlated with the microstructural features of the thixoformed plates.

    International Nuclear Information System (INIS)

    This work is part of a wider monitoring project of the agricultural soils in Lombardia, which aims to build a database of topsoil properties and the potentially toxic elements, organic pollutants and gamma emitting radionuclides that the topsoils contain. A total of 156 agricultural soils were sampled according to the LUCAS (Land Use/Cover Area frame statistical Survey) standard procedure. The aim was to provide a baseline to document the conditions present at the time of sampling. The results of the project concerning soil radioactivity are presented here. The aim was to assess the content of 238U, 232Th, 137Cs and 40K by measuring soil samples by gamma spectrometry. 238U, 232Th and 40K activities range 24–231, 20–70, and 242–1434 Bq kg−1 respectively. The geographic distribution of 238U reflects the geophysical framework of the Lombardia region: the soils with high content of uranium are distributed for the most part in the South Alpine belt, where the presence of magmatic rocks is widespread. These soils show an higher activity of 238U than of 232Th. The 238U activities become lower than 232Th when soils are located in the plain, originating from basic sedimentary rocks. 137Cs activity ranges 0.4–86.8 kBq m−2. The lowest activity of 137Cs is in the plain, whereas the highest is in the North on soils kept as lawn or pasture. The 137Cs activity of some samples suggests the presence of accumulation processes that lead to 137Cs enriched soils. This is the first survey of gamma emitting radionuclides in Lombardia that is based on the LUCAS standard sampling. The results from this monitoring campaign are important for the human radiation exposure and provide the zero point, which will be useful for assessing future effects due to external factors such as human activities. - Highlights: • A monitoring campaign of agricultural soils was carried out in Lombardia, Italy. • 156 topsoils were sampled according to the European standard procedure LUCAS.

    Full Text Available Abstract Background Detailed information regarding the number and organization of transfer RNA (tRNA genes at the genome level is becoming readily available with the increase of DNA sequencing of whole genomes. However the identification of functional tRNA genes is challenging for species that have large numbers of repetitive elements containing tRNA derived sequences, such as Bos taurus. Reliable identification and annotation of entire sets of tRNA genes allows the evolution of tRNA genes to be understood on a genomic scale. Results In this study, we explored the B. taurus genome using bioinformatics and comparative genomics approaches to catalogue and analyze cow tRNA genes. The initial analysis of the cow genome using tRNAscan-SE identified 31,868 putative tRNA genes and 189,183 pseudogenes, where 28,830 of the 31,868 predicted tRNA genes were classified as repetitive elements by the RepeatMasker program. We then used comparative genomics to further discriminate between functional tRNA genes and tRNA-derived sequences for the remaining set of 3,038 putative tRNA genes. For our analysis, we used the human, chimpanzee, mouse, rat, horse, dog, chicken and fugu genomes to predict that the number of active tRNA genes in cow lies in the vicinity of 439. Of this set, 150 tRNA genes were 100% identical in their sequences across all nine vertebrate genomes studied. Using clustering analyses, we identified a new tRNA-GlyCCC subfamily present in all analyzed mammalian genomes. We suggest that this subfamily originated from an ancestral tRNA-GlyGCC gene via a point mutation prior to the radiation of the mammalian lineages. Lastly, in a separate analysis we created phylogenetic profiles for each putative cow tRNA gene using a representative set of genomes to gain an overview of common evolutionary histories of tRNA genes. Conclusion The use of a combination of bioinformatics and comparative genomics approaches has allowed the confident identification of a

    The present study was undertaken to develop an effective adsorbent and to study the adsorption of Ethidium bromide and Ethidium monoazide bromide from aqueous solution using the CuO nanoparticles. The characteristics of CuO nanoparticles were determined and found to have a surface area 89.59m(2)/g. Operational parameters such as pH, contact time and adsorbent concentration, initial concentration and temperature were also studied. The amount of removal increases with the increase in pH from one to seven and reaches the maximum when the pH is nine. Adsorption data fitted well with the Langmuir, Freundlich and Florry-Huggins models. The results show that the best fit was achieved with the Langmuir isotherm equation with maximum adsorption capacities of 0.868 and 0.662mg/g for Ethidium bromide and Ethidium monoazide bromide, respectively. The adsorption process was found to follow pseudo-second-order kinetics. The calculated thermodynamic parameters, namely ΔG, ΔH and ΔS showed that adsorption of Ethidium bromide and Ethidium monoazide bromide was spontaneous and endothermic under examined conditions.

    Objective: Road traffic crashes (RTCs) are considered to be the second highest cause of mortality in Iran. The purpose of this study was to describe the morbidity and mortality of RTC during 2003-2008.Methods: Data were got from national health sources of Iran. These data included population, the number of RTCs,consequent fatalities, cause and place of death from 2003 to 2008.Results: RTC incidence rate increased from 868.5 per 100 000 population in the year 2003 to 1 643.6 in 2008. A total of 2 565 deaths from RTC were recorded in Yazd from 2003 to 2008. RTC mortality rate increased from 46.1 per 100 000 population in 2003 to 46.9 in 2006, then declined to 38.8 in 2008. During this time period, overall traffic injury incidence per 100 000 population increased from 368.8 in 2003 to 647.9 in 2006, then declined to 527.9 in 2008. Head injuries were the most common cause of road traffic-related mortality from 2003 to 2008. Following road traffic accidents, most of the deaths occurred before arriving hospital.Conclusions: Road traffic crash-related mortality and morbidity in Yazd in the recent six years are increased, but decreased in the last two years. This decline is most probably the result of a variety of interventions, including laws,police enforcement, improvements in traffic and transport,health care resources and media and public education.

    The financial viability of a 30 MW wind farm proposed to be set-up in St. Ana in Philippines was examined. It was found that project is viable if established by a company with a low hurdle rate (8.68%) and good reach to avail low cost financing from domestic financial institutions, who may have such packages for low-risk customers. Most of the private sector investors however have higher discount rates due to high financing costs, and higher risk premiums charged by financers. The viability was an issue at risk adjusted discount rate of 13.2%, a typical rate for private sector investors in Philippines. Scenarios for variation in base parameters as well for a variety of financial packages, including revenues from CDM were run. Although CDM revenues improve attractiveness of the project, viability remains an issue. A financing package, that may have a grant component (as with the Danida package in the past), can help project make viable in this case. (au)

  4. Hybrid cell sorters for on-chip cell separation by hydrodynamics and magnetophoresis

    International Nuclear Information System (INIS)

    The classification of cells is important for medical diagnosis and medicine research. A micro-scale analysis system for blood allows immediate diagnosis, regardless of time or location. Rapid handling of biological cells is required for the development of lab-on-a-chip and point-of-care technologies. In previous papers, the reported sample solution flow rates for hydrodynamic cell separation ranged from 0.1 to tens of μl min−1. This paper proposes a hybrid cell sorter that combines hydrodynamics and magnetophoresis. This cell sorter is proposed for improving the classification efficiency of a virtual impactor-based cell sorter and for permitting the hydrodynamic cell separation with high throughput. In addition, its performance has been evaluated in the classification of Jurkat cells and blood cells. In the Jurkat cell experiment, the classification efficiency of Jurkat cells at the major outlet decreased from 70 to 50.8% with the proposed hybrid scheme. The flow rate for cell separation was 1 ml min−1. The classification efficiency of red blood cells (RBCs) increased from 75.2 to 86.8% with the application of a magnetic field. Also, the classification efficiency of white blood cells (WBCs) decreased from 83.8 to 70.9% with an applied magnetic field. Experimental results demonstrated that the classification efficiency of blood cells can be modulated and enhanced by magnetophoresis and that the hybrid cell sorter has potential for lab-on-a-chip applications.

  5. Analysis of Zr in UZr (6%) alloy has been done by measuring complex compounds of Zr-Arsenazo III with spectrophotometric method

    International Nuclear Information System (INIS)

    Sample solutions were prepared by dissolving UZr 6% ingot using 1 M HF and 1 M HNO3 solvent at 95°C. Complex formation of UZr was made by the reaction of UZr (6%) with arsenazo III (0.1%). Verification of parameters for the formation and measurement of Zr-arsenazo III complex was performed by using standard solution of SRM SPEK Zr at various concentrations, arsenazo III (0.1%) and HCl. The result showed that the optimum condition for the formation of Zr-arsenazo III complex was at a wavelength of 666.3 nm, 9 N HCl, which was stable at 30 minutes to 3.5 hours and at a concentration of arsenazo III (0.1%) of 80 ppm. The analysis was done in the range of 0.04 ppm to 0.5 ppm with an accuracy and precision of 1.846% and 0.868% respectively. The Separation process of Zr from UZr alloy was required before the analysis because the presence of uranium in the sample might affect the analysis result significantly. The separation of Zr from uranium matrix was done by extraction using TBP/kerosene (7:3) with contacting time of 10 minutes. The analysis of Zr in the aqueous phase shows that the content of Zr is 5.28% with 91,84% recovery and 0,08% method precision (RSD). (author)

    Full Text Available In the present study, we prepared nattokinase-loaded self-double-emulsifying drug delivery system (SDEDDS and investigated its preliminary pharmacodynamics. The type and concentration of oil phase, inner aqueous phase and emulsifier were screened to prepare optimum nattokinase-loaded SDEDDS. Next, the optimum formulations were characterized based on microstructure, volume-weighted mean droplet size, self-emulsifying rate, yield, storage stability, in vitro release and in vivo pharmacodynamics studies. The water/oil/water multiple emulsions exhibited typical multiple structure, with relatively small volume-weighted mean droplet size 6.0 ± 0.7 μm and high self-emulsifying ability (self-emulsifying time <2 min. Encapsulation of nattokinase was up to 86.8 ± 8.2%. The cumulative release of nattokinase within 8 h was about 30%, exhibiting a sustained release effect. The pharmacodynamics study indicated that nattokinase-loaded SDEDDS could significantly prolong the whole blood clotting time in mouse and effectively improve the carrageenan-induced tail thrombosis compared with nattokinase solution. Moreover, we showed that SDEDDS could successfully self-emulsify into water/oil/water multiple emulsions upon dilution in dispersion medium with gentle stirring and effectively protect nattokinase activity in gastric environment. Our findings suggested that SDEDDS could be a promising strategy for peptide and protein drugs by oral administration.

    Within the international research environment, English is indisputably the lingua franca, and thus, the majority of the world's scientists must adapt to a second language. Linguistic barriers in science affect not only researchers' career paths but institutional productivity and efficiency as well. To address these barriers, we designed and piloted a specialized course, Scientific English. The pedagogical approach is based on English for specific purposes methodology in which curriculum and content are driven by the types of daily language used and interactions which occur in the participants' occupation, in this case, cancer research. The 11-week program was organized into three sections: presentation skill, meeting and discussion skills, and writing skills. Effectiveness of the course was measured by the number of participants able to produce the presentations and written products with a score of at least 75 of 100 possible points. From January to December 2008, participant scores averaged 90.4 for presentation and 86.8 for written products. The authors provide insights and recommendations on the development and delivery of the program. PMID:20623348

    Investors slowly but surely inched their way back into the utility sector during the first quarter of 1995. The result was a 2.68-percent increase in the Public Utilities Stock Index. While the return to investors was less than spectacular, it still beats the fourth-quarter`s scant increase of 0.14 percent-not to mention the 18-percent drop in the Dow Jones Electric Utilities Index and 17.9-percent decrease in the Dow Jones Gas Utilities Index for all of 1994. Nevertheless, the Public Utilities Stock Index paled in comparison to the record-breaking performances of the Dow Jones Industrial Average (+8.49 percent, to a record 4157.69), the S&P 500 (+9.02 percent, to a new high of 500.70), and the NASDAQ Composite (+8.68 percent, to an all-time high of 817.21). Why the disappointing performance by utility stocks last quarter? In th electric industry, look to the {open_quotes}D{close_quotes} word-as in deregulation. Electric utility stocks lagged noticeably behind gas utilities last quarter.

  9. Multidetector-row computed tomography-based clinical assessment of fondaparinux for treatment of acute pulmonary embolism and acute deep vein thrombosis in Japanese patients

    International Nuclear Information System (INIS)

    Unfractionated heparin (UFH) is the standard drug for the initial treatment of pulmonary embolism (PE) and deep vein thrombosis (DVT) in Japan, whereas fondaparinux is the standard drug in Europe and the United States. Here, we examine the efficacy and safety of fondaparinux in Japanese patients. In 2 randomized, open-label, multicenter studies, 80 Japanese patients with acute PE or DVT received either subcutaneous fondaparinux or intravenous UFH as a non-comparative reference, in a 3:1 ratio, for 5-10 days. Concomitant warfarin therapy was continued until Day 90. Multidetector-row computed tomography-based assessment showed that 57.9% and 45.9% of the patients with acute PE and acute proximal DVT had proximal DVT and PE as a complication, respectively. There was no recurrence of symptomatic venous thromboembolism. In the fondaparinux group, the respective improvement rates at the end of the initial treatment and follow-up periods were 71.4% and 86.8% for 42 patients with PE, and 57.8% and 83.3% for 46 patients with DVT; similar results were noted in the UFH group. One patient in the fondaparinux group experienced major bleeding during the initial treatment, but no such episode in the UFH group. Once-daily, subcutaneous fondaparinux is as effective and safe without monitoring as adjusted-dose intravenous UFH for the initial treatment of acute PE and DVT in Japanese patients. (author)

    A phase II study of recombinant human interferon gamma (rHuIFN-gamma) administered intravenously and intramuscularly was carried out in 84 patients with advanced renal cell carcinoma with the cooperation of 18 institutions throughout Japan. The eligibility of the patients and evaluation of the responses were undertaken according to the general criteria proposed by Drs. Koyama and Saito. Out of 84 cases entered in this phase II study, 62 patients were evaluable for antitumor effects. In the case of continuous administration of 8-12 X 10(6) U/m2/day interferon for 4 weeks, 32 patients were evaluable. The response rate was 6.3%. In the case of intermittent therapy of 40 X 10(6) U/m2/day interferon for 8 weeks, six out of 30 patients (20%) were evaluable as responders. Among them, one patient showed a complete response, all patients tolerated this type of interferon well. Major adverse effects were fever (86.8%), anorexia (67.1%), fatigue (53.9%) and leukopenia (42.1%). No life-threatening toxicities were found. The results of this study showed that rHuIFN-gamma had antitumor activity against renal cell carcinoma. PMID:3101607

    International Nuclear Information System (INIS)

    Objective: To assess the diagnostic value of PET/MR (positron emission tomography/magnetic resonance imaging) with FDG (18F-fluorodeoxyglucose) for lymph node staging in head and neck cancer. Materials and methods: This prospective study was approved by the local ethics committee; all patients signed informed consent. Thirty-eight patients with squamous cell carcinoma of the head and neck region underwent a PET scan on a conventional scanner and a subsequent PET/MR on a whole-body hybrid system after a single intravenous injection of FDG. The accuracy of PET, MR and PET/MR for lymph node metastases were compared using receiver operating characteristic (ROC) analysis. Histology served as the reference standard. Results: Metastatic disease was confirmed in 16 (42.1%) of 38 patients and 38 (9.7%) of 391 dissected lymph node levels. There were no significant differences between PET/MR, MR and PET and MR (p > 0.05) regarding accuracy for cervical metastatic disease. Based on lymph node levels, sensitivity and specificity for metastatic involvement were 65.8% and 97.2% for MR, 86.8% and 97.0% for PET and 89.5% and 95.2% for PET/MR. Conclusions: In head and neck cancer, FDG PET/MR does not significantly improve accuracy for cervical lymph node metastases in comparison to MR or PET

  13. Microbial electrolysis cells with polyaniline/multi-walled carbon nanotube-modified biocathodes

    International Nuclear Information System (INIS)

    In this paper, we modified biocathodes with PANI (Polyaniline)/MWCNT (Multi-Walled Carbon Nanotube) composites to improve hydrogen production in single-chamber, membrane-free biocathode MECs. The results showed that the hydrogen production rates increased with an increase in applied voltage. At an applied voltage of 0.9 V, the modified biocathode MECs achieved a hydrogen production rate of 0.67m3m−3d−1, current density of 205 Am−3, COD of 86.8%, coulombic efficiency of 72%, cathodic hydrogen recovery of 42%, and energy efficiency of 81% with respect to the electrical power input. LSV (Linear Sweep Voltammetry) scans, SEM (Scanning Electron Microscopy) images and DGGE (Denaturing Gradient Gel Electrophoresis) demonstrated that hydrogen production is catalyzed by the special biofilm attached on a modified biocathode, and the microorganism species and quantity present were significantly different between the modified biocathode and the non-modified biocathode. In general, the performance of MECs with modified biocathodes was improved in the presence of a higher current density and hydrogen generation rate. - Highlights: • Different PANI/MWCNT composites were prepared and used to modify biocathode in MECs. • The performance of MECs was improved by the modification. • 75% wt PANI/MWCNT modified biocathode showed the better capacity on hydrogen generation. • LVS, SEM, DGGE were determined to figure out the effect of modification on MECs. • PANI/MWCNT modified biocathode in MECs was first studied to push MECs technology forward

    Forest stand biomass serves as an effective indicator for monitoring REDD (reducing emissions fromdeforestation and forest degradation). Optical remote sensing data have been widely used to derive forestbiophysical parameters inspite of their poor sensitivity towards the forest properties. Microwave remotesensing provides a better alternative owing to its inherent ability to penetrate the forest vegetation.This study aims at developing optimal regression models for retrieving forest above-ground bole biomass(AGBB) utilising optical data from Landsat TM and microwave data from L-band of ALOS PALSARdata over Indian subcontinental tropical deciduous mixed forests located in Munger (Bihar, India). Spatialbiomass models were developed. The results using Landsat TM showed poor correlation (R^2 =0.295and RMSE=35 t/ha) when compared to HH polarized L-band SAR (R^2 =0.868 and RMSE=16.06 t/ha).However, the prediction model performed even better when both the optical and SAR were used simultaneously(R^2 =0.892 and RMSE=14.08 t/ha). The addition of TM metrics has positively contributed inimproving PALSAR estimates of forest biomass. Hence, the study recommends the combined use of bothoptical and SAR sensors for better assessment of stand biomass with significant contribution towardsoperational forestry.

    In this investigation, precipitation hardening Al-Zn-Mg alloy AA7039 was friction stir welded with and without in-process cooling in order to investigate the effect of in-process cooling on microstructure and tensile properties of the developed joints. The in-process cooling was employed using compressed air, liquid nitrogen and normal water. The effect of in-process cooling on the microstructure and mechanical properties of the weld joints was investigated by means of optical microscopy, tensile and microhardness tests. Fracture surfaces of the tensile tested weld joints were studied with a field emission scanning electron microscope (FE-SEM). The in-process cooling decreased the size of heat affected zones (HAZs) and thermo-mechanically affected zones (TMAZs) and also reduced the size of {alpha} aluminum grains in weld nugget zone (WNZ), TMAZs and HAZs. The hardness of the HAZ was found higher than WNZ and TMAZ of the joints developed with in-process cooling while reverse trend was observed for normal joints. In-process cooling with water was found to be more effective than other in-process cooling methods, and had ultimate tensile strength and percentage elongation equivalent to 73.5% and 86.8% of the base metal. In-process cooling changed the fracture location from heat affected zone to weld nugget zone.

    Full Text Available Techniques that employ 15N have proved to be an important tool in many areas of the agronomic and biomedical sciences. Nevertheless, their use is limited by methodological difficulties and by the price of compounds in the international market. Nitric compounds (15NO3- have attracted the interest of researchers. However, these compounds are not currently produced in Brazil. Thus, in the present work H15NO3 was obtained from the oxidation of anhydrous 15NH3. The method we used differs from the industrial process in that the absorption tower is replaced with a polytetrafluoroethylene-lined, stainless-steel hydration reactor. The process output was evaluated based on the following parameters: reaction temperature; ratio of reagents; pressure and flow of 15NH3(g through the catalyst (Pt/Rh. The results showed that, at the best conditions (500 ºC; 50 % excess O2; 0.4 MPa; and 3.39 g.min-1 of 15NH3, a conversion percentage (N-15NH3 to N-15NO3- of 62.2 %, an overall nitrogen balance (N-15NH3 + N-15NO3- of 86.8 %, and purity higher than 99 % could be obtained.

  17. Determination of the major tautomeric form of the covalently modified adenine in the (+)-CC-1065-DNA adduct by 1H and 15N NMR studies

    International Nuclear Information System (INIS)

    (+)-CC-1065 is an extremely potent antitumor antibiotic produced by Streptomyces zelensis. The potent cytotoxic effects of the drug are thought to be due to the formation of a covalent adduct with DNA through N3 of adenine. Although the covalent linkage sites between (+)-CC-1065 and DNA have been determined, the tautomeric form of the covalently modified adenine in the (+)-CC-1065-DNA duplex adduct was not defined. The [6-15N]deoxyadenosine-labeled 12-mer duplex adduct was then studied by 1H and 15N NMR. One-dimensional NOE difference and two-dimensional NOESY 1H NMR experiments on the nonisotopically labeled 12-mer duplex adduct demonstrate that the 6-amino protons of the covalently modified adenine exhibit two signals at 9.19 and 9.08 ppm. Proton NMR experiments on the [6-15N]deoxyadenosine-labeled 12-mer duplex adduct show that the two resonance signals for adenine H6 observed on the nonisotopically labeled duplex adduct were split into doublets by the 15N nucleus with coupling constants of 91.3 Hz for non-hydrogen-bonded and 86.8 Hz for hydrogen-bonded amino protons. The authors conclude that the covalently modified adenine N6 of the (+)-CC-1065-12-mer duplex adduct is predominantly in the doubly protonated form, in which calculations predict that the C6-N6 bond is shortened and the positive charge is delocalized over the entire adenine molecule

    Using the density functional method B3LYP with relativistic effective core potential (RECP) for Pu atom, the low-lying excited states (4∑+, 6∑+, 8∑+) for three structures of PuOH molecule were optimized. The results show that the ground state is X6∑+of the linear Pu-O-H (C∞v), its corresponding equilibrium geometry and dissociation energy are RPu-O=0.20595 nm, RO-H=0.09581 nm and -8.68 eV, respectively. At the same time, two other metastable structures [PuOH (Cs) and H-Pu-O (C∞v)] were found. The analytical potential energy function has also been derived for whole range using the many-body expansion method. This potential energy function represents the considerable topographical features of PuOH molecule in detail, which is adequately accurate in the whole potential surface and can be used for the molecular reaction dynamics research.

    2014-01-01

    The two-regime method (TRM) has been recently developed for optimizing stochastic reaction-diffusion simulations [M. Flegg, J. Chapman, and R. Erban, J. Roy. Soc. Interface, 9 (2012), pp. 859-868]. It is a multiscale (hybrid) algorithm which uses stochastic reaction-diffusion models with different levels of detail in different parts of the computational domain. The coupling condition on the interface between different modeling regimes of the TRM was previously derived for onedimensional models. In this paper, the TRM is generalized to higher dimensional reaction-diffusion systems. Coupling Brownian dynamics models with compartment-based models on regular (square) two-dimensional lattices is studied in detail. In this case, the interface between different modeling regimes contains either flat parts or right-angle corners. Both cases are studied in the paper. For flat interfaces, it is shown that the one-dimensional theory can be used along the line perpendicular to the TRM interface. In the direction tangential to the interface, two choices of the TRM parameters are presented. Their applicability depends on the compartment size and the time step used in the molecular-based regime. The two-dimensional generalization of the TRM is also discussed in the case of corners. © 2014 Society for Industrial and Applied Mathematics.

    Viral load testing for human immunodeficiency virus 1 (HIV-1) in resource-poor settings continues to be a challenge. Although antiretroviral therapy (ART) is being made available in developing countries, monitoring of viral load is not being done on a regular basis. The purpose of this study was to assess the utility of Cavidi version 3.0, which measures the plasma reverse transcriptase (RT) activity and compare its performance with molecular HIV viral load assays. In all, 125 HIV-1 and 13 HIV-2 positive samples were analyzed. The overall sensitivity of the assay was 86.8% and 94.1% for viral load >1000 copies/ml measured by Qiagen Artus HIV-1 RG RT PCR and Abbott RealTime HIV-1 PCR assays, respectively. Compared with the routine molecular viral load assays, Cavidi version 3.0 is inexpensive, user-friendly, the expenditure on infrastructure is minimal, and it can be used for monitoring of both HIV types.

    Saskatoon berries (Amelanchier alnifolia Nutt.) have significantly higher levels of anthocyanins (ACY) among berries with potential health benefits. The pomace is a by-product of juice extracted from berries and is a potential source of inexpensive polyphenols. The objectives of this study were to extract the maximum amount of total phenolics from saskatoon pomace, to determine the antioxidant activity, and to identify individual phenolic components. Pomace extracts showed high content of total phenolics, total ACY, and total flavonoids of 43.3, 2.8, and 10.3 g/kg of dried weight (DW) of pomace. A high oxygen radical absorbing capacity value of 119.4 μmol Trolox equivalents/g DW and free radical scavenging activity of pomace extract (200 ppm, 86.8%) were observed. Five major ACY, two flavonols, and three chlorogenic acids were identified and quantified in pomace extracts. This study shows that saskatoon berries pomace rich in antioxidant phenolics could be extracted by "green" solvents (water and ethanol) and used as suitable food product applications. PMID:24476215

    Leigh syndrome (MIM 25600), also known as infantile subacute necrotizing encephalomyelopathy, is a neurodegenerative disorder with characteristic bilateral symmetric lesions in basal ganglia and subcortical brain regions. It is commonly associated with systemic cytochrome c oxidase (COX) deficiency and mutations in the SURF1 gene (MIM 185620), encoding a putative assembly or maintenance factor of COX. The clinical course is dominated by neurodevelopmental regression, brain stem, and basal ganglia involvement (e.g., dystonia, apnea) with death often occurring before the age of 10 years. Herein, we present three sisters carrying a previously reported homozygous SURF1 mutation (c.868_869insT) that is predicted to result in a truncated protein with loss of function. Our patients show heterogeneous clinical findings with different distribution patterns of metabolic lesions in brain magnetic resonance imaging (MRI) as well as a Chiari malformation with hydrocephalus in one patient. However, all three siblings show an unusual long survival (12 years and>16 years). COX activity was not detectable in one patient and strongly reduced in the other two. We discuss these findings with respect to a review of the literature. A total of 15 additional patients with survival>14 years have been reported so far. Overall, no clear genotype-phenotype correlations are detectable among these patients. PMID:25111564

    Full Text Available Purpose: To determine the virulence factors produced by Escherichia coli isolated from extraintestinal infections, to study the drug resistance pattern in E. coli with special reference to extended spectrum β -lactamase (ESBL and to evaluate screening methods for ESBL. Methods: A total of 152 isolates of E. coli from various extraintestinal infections were screened for virulence factors such as haemolysin, surface hydrophobicity, serum resistance and protease. All the isolates were also studied for antibiotic susceptibility pattern using modified Kirby Bauer disk diffusion method. ESBL production was screened by standard disk diffusion method and confirmed using phenotypic confirmatory method. Results: Among 152 isolates, 36 (23.7% were haemolytic, 42 (27.6% were hydrophobic, 132 (86.8% were serum resistant and only four were positive for protease. Multiple virulence factor were observed in 67 (44% of isolates. Seventy-nine (51.4% isolates produced ESBL. ESBL producing isolates showed multidrug resistance. There was a significant association ( P < 0.001 between multiple virulence factors and ESBL production by extraintestinal E. coli . Conclusions: The present study shows the expression of virulence factors and multidrug resistance in E. coli isolated from various extraintestinal infections. The study also shows that appropriate methods of detecting drug resistance and ESBL production are required for the judicious use of antibiotics in managing these infections.

    Full Text Available Metal-carbon nanocomposites on the basis of polyacrylonitrile and compounds of metals (Fe, Ni, Co synthesized at IR-heating and studied by SEM, X-ray phase analysis, Raman scattering, IR Fourier spectroscopy are characterized by the carbon nanostructured amorphous graphite matrix with uniformly distributed nanoparticles of metals (10-30 nm, their oxides and compounds – FeNi3 and FeCo, multilayered carbon nanotubes (~ 7-22 nm, and in the composition of Fe-Co / C fullerene-like formations – C60. All nanocomposites feature high absorption of electromagnetic waves in the frequency range 20-40 GHz. Two absorption mechanisms are proposed: dielectric loss in the amorphous carbon matrix and scattering of electric and magnetic components by ferromagnetic inclusions. Absorption was – 8.68 dB for Fe-Ni / C, – 12.93 dB for Fe / C, and – 7.07 dB for Ni / C and for Fe-Co / C was found to be maximum in the whole range studied (more than – 40 dB with a peak of – 52.83 dB at 24.27 GHz, which is explained probably by both high nanocomposite electric conductivity 2 S / m and high specific magnetization of phase FeCo.

  8. A comparison of film and 3 digital imaging systems for natural dental caries detection: CCD, CMOS, PSP and film

    International Nuclear Information System (INIS)

    To evaluate the diagnostic accuracy of occlusal and proximal caries detection using CCD, CMOS, PSP and film system. 32 occlusal and 30 proximal tooth surfaces were radiographed under standardized conditions using 3 digital systems; CCD (CDX-2000HQ, Biomedysis Co., Seoul, Korea), CMOS (Schick, Schick Inc., Long Island, USA), PSP (Digora FMX, Orion Co./Soredex, Helsinki, Finland) and 1 film system (Kodak Insight, Eastman Kodak, Rochester, USA). 5 observers examined the radiographs for occlusal and proximal caries using a 5-point confidence scale. The presence of caries was validated histologically and radiographically. Diagnostic accuracy was evaluated using ROC curve areas (AZ). Analysis using ROC curves revealed the area under each curve which indicated a diagnostic accuracy. For occlusal caries, Kodak Insight film had an Az of 0.765, CCD one of 0.730, CMOS one of 0.742 and PSP one of 0.735. For proximal caries, Kodak Insight film had an Az of 0.833, CCD one of 0.832, CMOS one of 0.828 and PSP one of 0.868. No statistically significant difference was noted between any of the imaging modalities. CCD, CMOS, PSP and film performed equally well in the detection of occlusal and proximal dental caries. CCD, CMOS and PSP-based digital images provided a level of diagnostic performance comparable to Kodak Insight film.

    A prospective, comparative study of the prevalence of enteric protozoa was determined among human immunodeficiency virus (HIV)- positive and HIV-negative men who have sex with men (MSM) in Sydney, Australia. A total of 1,868 patients submitted stool specimens; 1,246 were from MSM (628 HIV positive and 618 HIV positive) and 622 from non-MSM were examined over a 36-month period. A total of 651 (52.2%) stool specimens from MSM were positive for protozoa compared with 85 (13%) from non-MSM. There was a significant difference in the prevalence of Blastocystis hominis, Endolimax nana, Entamoeba histolytica/dispar complex, Entamoeba hartmanni, Iodamoeba butschlii, and Enteromonas hominis detected between MSM and non-MSM (PEntamoeba histolytica was found in 3 patients, E. dispar in 25, and E. moshkovskii in 17, all of whom were MSM. When compared with a control group, MSM were significantly more likely to harbor intestinal protozoa and have multiple parasites present. The results of this study show high rates of enteric parasites persist in MSM and highlight the importance of testing for intestinal parasites in MSM. This is the first report of E. moshkovskii from MSM. PMID:17360882

    Full Text Available Pneumococcal infections are a major cause of morbidity and mortality in developing countries. The introduction of pneumococcal conjugate vaccines (PCVs has dramatically reduced the incidence of pneumococcal diseases. PCVs are not currently being used in Algeria. We conducted a prospective study from 2005 to 2012 in Algeria to determine antimicrobial drug resistance and serotype distribution of Streptococcus pneumoniae from children with pneumococcal disease. Among 270 isolated strains from children, 97 (36% were invasive disease; of these, 48% were not susceptible to penicillin and 53% not susceptible to erythromycin. A high rate of antimicrobial nonsusceptibility was observed in strains isolated from children with meningitis. The serotype distribution from pneumococci isolated from children with invasive infections was (by order of prevalence: 14, 1, 19F, 19A, 6B, 5, 3, 6A and 23F. Multidrug resistance was observed in serotypes 14, 19F, 19A and 6B. The vaccine coverage of serotypes isolated from children aged <5 years was 55.3% for PCV7, 71.1% for PCV10 and 86.8% for PCV13. Our results highlight the burden of pneumococcal disease in Algeria and the increasing S. pneumoniae antibiotic resistance. The current pneumococcal vaccines cover a high percentage of the circulating strains. Therefore, vaccination would reduce the incidence of pneumococcal disease in Algeria.

    Radial-velocity measurements and sine-curve fits to the orbital radial velocity variations are presented for the last eight close binary systems analyzed the same way as in the previous papers of this series: QX And, DY Cet, MR Del, HI Dra, DD Mon, V868 Mon, ER Ori, and Y Sex. For another seven systems (TT Cet, AA Cet, CW Lyn, V563 Lyr, CW Sge, LV Vir and MW Vir) phase coverage is insufficient to provide reliable orbits but radial velocities of individual components were measured. Observations of a few complicated systems observed throughout the DDO close-binary program are also presented; among them an especially interesting is the multiple system V857 Her which - in addition to the contact binary - very probably contains one or more sub-dwarf components of much earlier spectral type. All suspected binaries which were found to be most probably pulsating stars are briefly discussed in terms of mean radial velocities and projected rotation velocities (v sin i) as well as spectral type estimates.

  12. The fusion rules for the Temperley–Lieb algebra and its dilute generalization

    International Nuclear Information System (INIS)

    The Temperley–Lieb (TL) family of algebras is well known for its role in building integrable lattice models. Even though a proof is still missing, it is agreed that these models should go to conformal field theories in the thermodynamic limit and that the limiting vector space should carry a representation of the Virasoro algebra. The fusion rules are a notable feature of the Virasoro algebra. One would hope that there is an analogous construction for the TL family. Such a construction was proposed by Read and Saleur (2007 Nucl. Phys. B 777 316) and partially computed by Gainutdinov and Vasseur (2013 Nucl. Phys. B 868 223–70) using the bimodule structure over the TL algebras and the quantum group Uq (sl2).We use their definition for the dilute Temperley–Lieb (dTL) family, a generalization of the original TL family. We develop a new way of computing fusion by using induction and show its power by obtaining fusion rules for both dTL and TL. We recover those computed by Gainutdivov and Vasseur and new ones that were beyond their scope. In particular, we identify a set of irreducible TL- or dTL-representations whose behavior under fusion is that of some irreducibles of the minimal models of conformal field theory. (paper)

    The utilization of scrap tires still obtains a remarkable importance from the aspect of unloading the environment from non-degradable waste [1]. One of the most prospective ways for scrap tires reuse is a production of composite materials [2] This research must be considered as a continuation of previous investigations [3, 4]. It is devoted to the clarification of some functional properties, which are considered important for the view of practical applications, of the composite material. Some functional properties of the material were investigated, for instance, the compressive stress at different extent of deformation of sample (till 67% of initial thickness) (LVS EN 826) [5] and the resistance to UV radiation (modified method based on LVS EN 14836) [6]. Experiments were realized on the purposefully selected samples. The results were evaluated in the correlation with potential changes of Shore C hardness (Shore scale, ISO 7619-1, ISO 868) [7, 8]. The results showed noticeable resistance of the composite material against the mechanical influence and ultraviolet (UV) radiation. The correlation with the composition of the material, activity of binder, definite technological parameters, and the conditions supported during the production, were determined. It was estimated that selected properties and characteristics of the material are strongly dependent from the composition and technological parameters used in production of the composite material, and from the size of rubber crumb. Obtained results show possibility to attain desirable changes in the composite material properties by changing both the composition and technological parameters of examined material.

  16. Increased Chromosomal Radiosensitivity in Women Carrying BRCA1/BRCA2 Mutations Assessed With the G2 Assay

    International Nuclear Information System (INIS)

    Purpose: Several in vitro studies suggest that BRCA1 and BRCA2 mutation carriers present increased sensitivity to ionizing radiation. Different assays for the assessment of deoxyribonucleic acid double-strand break repair capacity have been used, but results are rather inconsistent. Given the concerns about the possible risks of breast screening with mammography in mutation carrier women and the potentially damaging effects of radiotherapy, the purpose of this study was to further investigate the radiosensitivity of this population. Methods and Materials: The G2 chromosomal radiosensitivity assay was used to assess chromosomal breaks in lymphocyte cultures after exposure to 1 Gy. A group of familiar breast cancer patients carrying a mutation in the BRCA1 or BRCA2 gene (n = 15) and a group of healthy mutation carriers (n = 5) were investigated and compared with a reference group of healthy women carrying no mutation (n = 21). Results: BRCA1 and BRCA2 mutation carriers had a significantly higher number of mean chromatid breaks per cell (p = 0.006) and a higher maximum number of breaks (p = 0.0001) as compared with their matched controls. Both healthy carriers and carriers with a cancer history were more radiosensitive than controls (p = 0.002 and p = 0.025, respectively). Age was not associated with increased radiosensitivity (p = 0.868). Conclusions: Our results indicate that BRCA1 and BRCA2 mutation carriers show enhanced radiosensitivity, presumably because of the involvement of the BRCA genes in deoxyribonucleic acid repair and cell cycle control mechanisms.

    International Nuclear Information System (INIS)

    This study was designed to evaluate the prognostic significance of Magnetic resonance angiography(MRA) in patients with cerebral infarction. Magnetic Resonance Imaging(MRI) and 2 dimensional or 3 dimensional Time-of-Flight MRA were performed subsequently in 83 patients with cerebral infarction proven by brain CT and clinical manifestations, using GE Signa Advantage 1.5 T. We classified the size of infarction on MRI as Extent I( 6 cm) and classified the intracranial vascular occlusion according to visualizations of intracranial vascular branches on MRA as Grade 0, Grade I, Grade II, Grade III. And we evaluated clinical outcomes of these patients according to Rankin's disability scale, compared with MRI and MRA. In 72 cases(86.8%), the larger the size of infarction on MRI, the more severe vascular occlusion on MRA, the worse the clinical outcomes were noted(p < 0.01). However, in 7 cases(8.4%) who showed huge cerebral infarction on MRI with low grade intracranial vascular occlusion on MRA, the clinical outcomes were improved. In 4 cases(4.8%) who noted small sized cerebral infarction on MRI with high grade vascular occlusion on MRA, the clinical outcomes were worsened. MRA provides additional useful information to that provided by MRI in predicting the prognosis of patients with cerebral infarction

    A high diet quality index based on Swedish nutrition recommendations has previously been associated with reduced risk of cardiovascular disease and mortality in the Malmö Diet and Cancer (MDC) cohort. The aim of the present study was to investigate whether this diet quality index was associated with the risk for type 2 diabetes. Of 26,868 participants (44-74 years) in the MDC cohort study, 3838 type 2 diabetes cases were identified from registers during 17 years of follow-up. A diet quality index (from a modified diet history method) was constructed based on adherence to the recommended intakes of saturated fat, polyunsaturated fat, fish, fiber, fruit and vegetables, and sucrose. After adjusting for potential confounders, we observed no significant association between the diet quality index and type 2 diabetes risk. The HR for the highest vs. lowest index category was 1.06 (95% CI: 0.94, 1.20; p-trend = 0.56). Because of the protective associations shown for cardiovascular disease and mortality, the specific dietary components that were chosen to represent adherence to the recommendations may be less applicable to type 2 diabetes risk.

    Full Text Available Introduction/aims: Satisfaction of inpatients with served food within a hospital care system still constitutes one of the main attempts to modernize food services. The impact of type of menu, food category, hospital centre and timetable on the meals wastage produced in different Spanish healthcare settings, was evaluated. Methods: Meal wastage was measured through a semiquantitative 5-point scale ("nothing on plate"; "¼ on plate"; "half on plate"; "¾ on plate" and "all on plate". The study was carried out in two periods of three months each in 2010 and 2011. A trained person took charge of measuring plate waste classified into 726 servings belonging to 11 menus. In total 31,392 plates were served to 7,868 inpatients. A Kruskal-Wallis non-parametric test (P 0.05. Conclusion: Visual inspections of plate waste might be useful to optimize type and quality of menus served. The type of menu served and the food category could have a great influence on food acceptability by the inpatients studied.

  2. On performance testing of gasturbine nozzle blades in a corrosive medium

    International Nuclear Information System (INIS)

    Performance of the nozzle blades GTU manufactured from EhI 868 (KhN60V) heat resistant material having a relatively low yield strength level has been investigated in a complex program under sea salt gas flow conditions. The high temperature fatigue testing in the sea salt gas flow environment has been made at dfferent minimum exit edge temperatures, i.e., 500 deg C, 600 deg C, and 700 deg C. The tests of a number of superalloys reveals that high temperature fatigue strength is enhanced by aluminizing. The testing of blades has been continued following the formation of high temperature fatigue cracks in order to study crack growth kinetics. The entrance and exit edge material has been studied by metallographic techniques. The cracks in the exit edge having tsub(max) = 1050 deg C are found to develop along grain boundaries. In the entrance edge having tsub(max) 985 deg C, the cracks propagate in complicated mode with the intergranular mechanism being predominant

  3. Removing and recovering of uranium from the acid mine waters by using ion exchange resin

    International Nuclear Information System (INIS)

    Ion exchange using resins is one of the few processes capable of reducing ionic contaminants in effluents to very low levels. In this study the process was used to remove and recovery uranium from acid mine waters at Pocos de Caldas-MG Uranium Mining and Milling Plant. The local mineralogical features, allied to the biogeochemical phenomena, owing to presence of pyrite in the rock piles, moreover another factors, resulting acid drainage with several pollutants, including uranium ranging from 6 to 14 mg/l, as sulfate complex, that can be removed by anionic exchanger. The iron interference is eliminated by lime pretreatment of water, increasing pH from 2.6 to 3.3-3.8 to precipitate this cation, without changing the uranium amount. Eight anionic resins were tested, based on the uranium loading, in sorption studies. Retention time, and pH influence was verified for the exchanger chose. With breakthrough of 1 mg U/L and 10 mg U/l in the feed solution, the uranium decontamination level was 94%. Typical values of loading resin were 20-30 g U/l and 70-90 g SO4/l. Uranium elution was done with Na Cl solution. Retention time, saline, and acid concentration were the parameters studied. The concentrate, obtained from the eluate by ammonia precipitation, presented uranium (86,8% as U3 O8) and impurities within commercial specifications. (author)

    Full Text Available Several research studies suggest a link between parents’ emotion socialization and children’s social competence and behavior problems. Parents contribute to their children’s emotion socialization, more directly, through responses to their children’s emotions. Early emotion socialization experiences with parents establish patterns of emotion experience, expression, and regulation that children carry into their broader social circles. Few scales exist to document parents’ responses to children’s emotions. The aim of this study was to document mothers’ responses to their children’s sadness, anger, fear, and being overjoyed. A study sample of 868 mothers of preschoolers completed the questionnaire in Turkey. The validity and reliability properties of the Responses to Children’s Emotions (RCE Questionnaire were also examined. We found that mothers in Turkey preferred to respond differently to children’s different emotions. Mothers’ responses generally did not differ according to the gender of their children; the only difference was found for sadness. Mothers’ responses to their children’s emotions related to the children’s and mothers’ ages, monthly family income, levels of mothers’ education, mothers’ employment status, birth order of children, and the city they lived in. This study is important in that it is the first to document mothers’ emotion socialization strategies for their children in terms of one positive and three negative emotions.

    Detecting and classifying global dermoscopic patterns are crucial steps for detecting melanocytic lesions from non-melanocytic ones. An important stage of melanoma diagnosis uses pattern analysis methods such as 7-point check list, Menzies method etc. In this paper, we present a novel approach to investigate texture analysis and classification of 5 classes of global lesion patterns (reticular, globular, cobblestone, homogeneous, and parallel pattern) in dermoscopic images. Our statistical approach models the texture by the joint probability distribution of filter responses using a comprehensive set of the state of the art filter banks. This distribution is represented by the frequency histogram of filter response cluster centers called textons. We have also examined other two methods: Joint Distribution of Intensities (JDI) and Convolutional Restricted Boltzmann Machine (CRBM) to learn the pattern specific features to be used for textons. The classification performance is compared over the Leung and Malik filters (LM), Root Filter Set (RFS), Maximum Response Filters (MR8), Schmid, Laws and our proposed filter set as well as CRBM and JDI. We analyzed 375 images of the 5 classes of the patterns. Our experiments show that the joint distribution of color (JDC) in the L*a*b* color space outperforms the other color spaces with a correct classification rate of 86.8%.

    The evidence regarding older parental age and incidence of mood disorder symptoms in offspring is limited, and that which exists is mixed. We sought to clarify these relationships by using data from the Western Australian Pregnancy Cohort (Raine) Study. The Raine Study provided comprehensive data from 2,900 pregnancies, resulting in 2,868 live born children. A total of 1,220 participants completed the short form of the Depression Anxiety Stress Scale (DASS-21) at the 20-year cohort follow-up. We used negative binomial regression analyses with log link and with adjustment for known perinatal risk factors to examine the extent to which maternal and paternal age at childbirth predicted continuous DASS-21 index scores. In the final multivariate models, a maternal age of 30-34 years was associated with significant increases in stress DASS-21 scores in female offspring relative to female offspring of 25- to 29-year-old mothers. A maternal age of 35 years and over was associated with increased scores on all DASS-21 scales in female offspring. Our results indicate that older maternal age is associated with depression, anxiety, and stress symptoms in young adult females. Further research into the mechanisms underpinning this relationship is needed. PMID:26569038

    Background/Aims Nicotinamide adenine dinucleotide phosphate oxidase (NOX)-mediated reactive oxygen species contribute to various liver diseases, including hepatocellular carcinoma (HCC). Uncertainties remain regarding the prognostic relevance of NOX1 and NOX4 protein expression in HCC. Methods NOX1 and NOX4 protein expression was examined by using immunohistochemistry in tumor tissue from 227 HCC patients who underwent hepatectomy. Results High immunoreactivity for NOX1 was observed in 197 (86.8%) of the 227 HCC cases and low immunoreactivity for NOX4 in 112 (49.3%). NOX1 and NOX4 proteins had opposite prognostic effects. High NOX1 expression was an independent predictor of both shorter recurrence-free survival (RFS) (p<0.01) and shorter overall survival (OS) (p=0.01). Low NOX4 expression was an independent predictor of both shorter RFS (p<0.01) and shorter OS (p=0.01). Subgroup analysis showed that, among patients with normal α-fetoprotein levels, patients with tumor size ≤5.0 cm and patients in Barcelona Clinic Liver Cancer stage A, high NOX1 expression had unfavorable effects on RFS, whereas low NOX4 expression had unfavorable effects on both RFS and OS. Conclusions These findings demonstrated that NOX1 and NOX4 protein expression had opposite prognostic effects for HCC patients. Moreover, both proteins had prognostic value in HCC patients with normal α-fetoprotein levels or with early-stage HCC. PMID:27282266

    Very few reports have been published on lifetime risk (LTR) of stroke by blood pressure (BP) group. This study included participants in the Radiation Effects Research Foundation Adult Health Study who have been followed up by biennial health examinations since 1958. We calculated the LTR of stroke for various BP-based groups among 7847 subjects who had not been diagnosed with stroke before the index age of 55 years using cumulative incidence analysis adjusting for competing risks. By 2003, 868 subjects had suffered stroke (512 (58.9%) were women and 542 (62.4%) experienced ischemic stroke). BP was a significant factor in determining risk of stroke for men and women, with distributions of cumulative risk for stroke significantly different across BP groups. The LTR of all-stroke for normotension (systolic BP/diastolic BP 160/100 mm Hg) were 13.8-16.9-25.8-25.8% in men and 16.0-19.9-24.0-30.5% in women, respectively (P bomb survivor subjects experienced stroke over their lifetime from the age of 55 years. Long-term stroke risks were elevated in those with hypertension (> 140/90 mm Hg) at any of the index ages of 45, 55, 65 and 75 years. PMID:21326305

  10. Survival and prognostic factors in non-small cell lung cancer patients with spinal bone metastases. A retrospective analysis of 303 patients

    International Nuclear Information System (INIS)

    For palliative care of spinal bone metastases, stability assessment is of crucial importance. Pathological fractures, instability-related patient immobility and the extent of bone metastasis have been reported to affect patient outcome and these parameters have therefore been used for treatment stratification. We report on stability-dependent fracture and survival rates in over 300 non-small cell lung cancer (NSCLC) patients. Data from 303 patients with 868 osteolytic metastases treated with radiotherapy (RT) between 2000 and 2012 were evaluated retrospectively. In NSCLC patients with bone metastases only, the retrospective 6- and 12-month overall survival (OS) rates were 76.7 and 47.2%, respectively. In patients with additional non-bone distant metastases, these values were 60.0 and 34.0%, respectively. Survival rates were significantly lower in patients with multiple bone metastases and in those suffering pathological fractures (p=0.017). No significant impact of histological type, location of spinal lesions or treatment regime was detected. Furthermore, stability assessment revealed no influence of vertebral column stability on patient outcome (p=0.739). Our analysis demonstrated a correlation between the pathological fractures of bone lesions, the number of bone metastases, additional distant metastases and survival. The results offer a rationale for future prospective investigations. (orig.)

  11. Comparison of initial high resolution computed tomography features in viral pneumonia between metapneumovirus infection and severe acute respiratory syndrome

    International Nuclear Information System (INIS)

    Objective: To review and compare initial high resolution computed tomography (HRCT) findings in patients with metapneumovirus pneumonia and severe acute respiratory syndrome (SARS-Coronovirus). Materials and methods: 4 cases of metapneumovirus pneumonia (mean age of 52.3 years) in an institutional outbreak (Castle Peak Hospital) in 2008 and 38 cases of SARS-coronovirus (mean age of 39.6 years) admitted to Tuen Mun hospital during an epidemic outbreak in 2003 were included. HRCT findings of the lungs for all patients were retrospectively reviewed by two independent radiologists. Results: In the metapneumovirus group, common HRCT features were ground glass opacities (100%), consolidation (100%), parenchymal band (100%), bronchiectasis (75%). Crazy paving pattern was absent. They were predominantly subpleural and basal in location and bilateral involvement was observed in 50% of patients. In the SARS group, common HRCT features were ground glass opacities (92.1%), interlobular septal thickening (86.8%), crazy paving pattern (73.7%) and consolidation (68%). Bronchiectasis was not seen. Majority of patient demonstrated segmental or lobar in distribution and bilateral involvement was observed in 44.7% of patients. Pleural effusion and lymphadenopathy were of consistent rare features in both groups. Conclusion: Ground glass opacities, interlobular septal thickening and consolidations were consistent HRCT manifestations in both metapneumovirus infection and SARS. The presence of bronchiectasis (0% in SARS) may point towards metapneumovirus while crazy paving pattern is more suggestive of SARS.

  12. The Effect of Annealing on Nanothick Indium Tin Oxide Transparent Conductive Films for Touch Sensors

    Full Text Available This study aims to discuss the sheet resistance of ultrathin indium tin oxide (ITO transparent conductive films during the postannealing treatment. The thickness of the ultrathin ITO films is 20 nm. They are prepared on B270 glass substrates at room temperature by a direct-current pulsed magnetron sputtering system. Ultrathin ITO films with high sheet resistance are commonly used for touch panel applications. As the annealing temperature is increased, the structure of the ultrathin ITO film changes from amorphous to polycrystalline. The crystalline of ultrathin ITO films becomes stronger with an increase of annealing temperature, which further leads to the effect of enhanced Hall mobility. A postannealing treatment in an atmosphere can enhance the optical transmittance owing to the filling of oxygen vacancies, but the sheet resistance rises sharply. However, a higher annealing temperature, above 250°C, results in a decrease in the sheet resistance of ultrathin ITO films, because more Sn ions become an effective dopant. An optimum sheet resistance of 336 Ω/sqr was obtained for ultrathin ITO films at 400°C with an average optical transmittance of 86.8% for touch sensor applications.

    The failure of wastewater treatment plants to produce effluents of a high microbiological quality is a matter of great concern in terms of water resource pollution. A more serious concern is that this water source is used by communities in developing countries for multiple purposes, which include drinking, recreation and agriculture. The current study investigated the prevalence and potential health risks of enteropathogenic bacteria (Salmonella typhimurium, Shigella dysenteriae and Vibrio cholerae) in the treated effluents of three selected South African Wastewater Treatment Works as well as their receiving water bodies. Culture-based and polymerase chain reaction techniques were used to detect and identify the pathogenic bacteria. The conventional methods revealed that of the 272 water samples collected, 236 samples (86.8%) tested presumptively positive for Salmonella spp., 220 samples (80.9%) for Shigella spp. and 253 samples (93.0%) for V. cholerae. Molecular test results indicated that out of the randomly selected presumptive positive samples (145), zero to 60% of samples were positive for S. typhimurium and S. dysenteriae and 20% to 60% for V. cholerae. For the health risk assessment, the daily combined risk of S. typhimurium, S. dysenteriae and V. cholerae infection was above the lowest acceptable risk limit of 10(-4) as estimated by the World Health Organization for drinking water. This study showed that the target treated wastewater effluents and their receiving water bodies could pose a potential health risk to the surrounding communities. PMID:25777950

    The main objective of this research is to investigate the effect of foliar applications of boron at different growth stages on yield and yield parameters of wheat. The contribution of boron in achieving yield parameters is described by second degree polynomial equations, with high statistical confidence (p<0.01; F theoretical < F calculated, according to ANOVA test, for Alfa = 0.05). Regression analysis, based on R{sup 2} values obtained, made it possible to evaluate the particular contribution of boron to the realization of yield parameters. This was lower for spike length (R{sup 2} = 0.812), thousand seeds weight (R{sup 2} = 0.850) and higher in the case of the number of spikelets (R{sup 2} = 0.936) and the number of seeds on a spike (R{sup 2} = 0.960). These results confirm that boron plays an important part in achieving the number of seeds on a spike in the case of wheat, as the contribution of this element to the process of flower fertilization is well-known. In regards to productivity elements, the contribution of macroelements to yield quantity is clear, the contribution of B alone being R{sup 2} = 0.868.

  15. Study of radiological risk at the Regional Hospital of Trujillo-Peru

    International Nuclear Information System (INIS)

    The irradiation doses have been measured in operators, patients and members of public, who attend the diagnostic service of the Hospital Regional Docente in Trujillo, Peru by using TLD-100 and TLD-200. For cranium test, the results are 8,68 x 10-3 mSv in operators and 7,8 x 10-4 mSv in members of the public. It means a fatal cancer risk of 3,7 x 10-7 and 3,9 x 10-8, respectively. For patients, the equivalent doses in the examined organs are 0,181 mSv in lung; 4,982 mSv in spine; 6,466 mSv in abdomen; 6,039 mSv in pelvis and 2,174 mSv in cranium. In order to maximize benefits for patients, a quality control program was carried out in x-ray equipment. It consisted in the measurement of an effective, average and maximum kilovoltage, as well as in the determination of the HVL, linearity, exposition time and coincidence between luminous and radiation fields. It was concluded that the measured doses are similar to the international ones reported. In the same way, it is indicated that it is possible to reduce risks in patients and operators by regulating kilo-voltages, adjusting the radiation fields and electronic calibration equipment.

    Full Text Available The challenge to maternal well-being with associated maternal wastages especially in labor has remained unsurmountable across the three tiers of health care delivery in Nigeria. This study aimed to determine and compare the factors that influence utilization of the partograph in primary, secondary, and tertiary health care delivery levels in Calabar, Nigeria. This was a descriptive study, using a self-administered semistructured questionnaire on 290 consenting nonphysician obstetric care workers, purposively recruited. The mean age of the respondents was 40.25±8.68 with a preponderance of females (92.4%. Knowledge of the partograph and previous partograph training had statistically significant relationship with its utilization among respondents from the tertiary and general hospitals. The level of knowledge was higher among workers in the general hospital than those working in the university teaching hospital. Nurses/midwives in the three levels of care were significantly more knowledgeable in partograph use than other nonphysician obstetric care workers. Lack of detailed knowledge of the partograph, its nonavailability and poor staff strength in the study centers were factors militating against its ease of utilization. The authors recommend periodic in-service training and provision of partograph in labor rooms in all maternity wards in our environment.

    Helicobacter pylori infection is usually acquired in early childhood and it can persist throughout life without antibiotic treatment. This study aimed to compare the accuracy of the noninvasive H. pylori Stool Antigen Test-applied on the stool samples with the invasive gold standart Rapid Urease Test-applied on the gastric biopy samples of patients with upper gastrointestinal complaints. After endoscopy, biopsy and stool specimens were taken in 122 patients. The infection was detected with rapid urease test which is accepted as gold standart test. Rapid, one-step H. pylori card test was applied to all patients stool specimens. In this study 106 of the 122 patients (86.8%) were positive for H. pylori infection, while 16 of the 122 patients (13.2%) were negative. H. pylori card test was negative in 13 of the 16 patients and was positive in 98 of the 106. The sensitivity, specifity, positive and negative predictive values were 92.45%, 81.25%, 97.02%, and 61.90%, respectively. H. pylori card test is rapid, easy, noninvasive and inexpensive methods for detection H. pylori infection. This test showed high sensitivity and specificity. Additionally, it may be a good alternative to invasive tests for the detection of H. pylori infections especially in children. PMID:26887240

    Full Text Available It is estimated by the World Health Organization (WHO that 3% of the world’s population (194 million have diabetes and the prevalence is expected to double by the year 2025 to 6.3% [1]. According to WHO, it is estimated that there were 88,000 diabetics in Libya the year 2000. This prevalence is estimated to reach 245,000 diabetics by the year 2030, (see figure below. In Libya, according to local epidemiological studies, the prevalence for known diabetic patients aged over 20 years was 3.8% [2]. As 50% of type 2 diabetic patients are unaware of their diabetes “undiagnosed”, the actual prevalence is probably higher. In the town of Tajoura, the west part of Libya; 7.9% of all adult members of 1094 randomly selected families (2996 persons aged between 20 and 75 years had diabetes [3]. In Benghazi, in the eastern part of Libya, screening of randomly selected group of 868 subjects revealed that about 23% above age of 20 years were glucose intolerant, two-thirds had diabetes and the rest had impaired glucose tolerance [4]. From these two Libyan cohorts, we estimate the adult diabetic population in Libya to be at least 300,000 at present.

All available 16S rRNA gene sequences recovered from wetlands in public databases were retrieved. In November 2012, a total of 12677 bacterial and 1747 archaeal sequences were collected in GenBank. All the bacterial sequences were assigned into 6383 operational taxonomic units (OTUs 0.03, representing 31 known bacterial phyla, predominant with Proteobacteria (2791 OTUs, Bacteroidetes (868 OTUs, Acidobacteria (731 OTUs, Firmicutes (540 OTUs, and Actinobacteria (418 OTUs. The genus Flavobacterium (11.6% of bacterial sequences was the dominate bacteria in wetlands, followed by Gp1, Nitrosospira, and Nitrosomonas. Archaeal sequences were assigned to 521 OTUs from phyla Euryarchaeota and Crenarchaeota. The dominating archaeal genera were Fervidicoccus and Methanosaeta. Rarefaction analysis indicated that approximately 40% of bacterial and 83% of archaeal diversity in wetland soils and sediments have been presented. Our results should be significant for well-understanding the microbial diversity involved in worldwide wetlands.

    Bioconcentration factors (BCFs) are of great importance for ecological risk assessment of organic chemicals. In this study, a quantitative structure-activity relationship (QSAR) model for fish BCFs of 8 groups of compounds was developed employing partial least squares (PLS) regression, based on lin-ear solvation energy relationship (LSER) theory and theoretical molecular structural descriptors. The guidelines for development and validation of QSAR models proposed by the Organization for Economic Co-operation and Development (OECD) were followed. The model results show that the main factors governing IogBCF are Connolly molecular area (CMA), average molecular polarizability (α) and mo-lecular weight (Mw). Thus molecular size plays a critical role in affecting the bioconcentration of organic pollutants in fish. For the established model, the multiple correlation coefficient square (R2Y)2=0.868, the root mean square error (RMSE)=0.553 log units, and the leave-many-out cross-validated Q2CUM=0.860, indicating its good goodness-of-fit and robustness. The model predictivity was evaluated by external validation, with the external explained variance (Q2EXT)=0.755 and RMSE=0.647 log units. Moreover, the applicability domain of the developed model was assessed and visualized by the Williams plot. The developed QSAR model can be used to predict fish logBCF for organic chemicals within the application domain.

    Full Text Available Sixteen Alibernet wine samples, originated from three most important Slovak vineyard regions, were evaluated spectrophotometrically for the content of total polyphenols, content of total anthocyanins, antioxidant activity and wine colour density. The determined total polyphenol contents in observed wines ranged from 2141 to 4274 mg gallic acid per liter (average content was 3057 mg gallic acid/L and total anthocyanin contents ranged from 73.4 to 791.2 mg/L (average content was 403.4 mg/L. Determined values of antioxidant activity were within the interval 54.8 – 86.8% (average value was 74.5% and the values of wine colour density varied between 0.944 and 4.592 (average value was 2.317. The statistical evaluation of the obtained results confirmed only weak linear correlation between total polyphenol content and total anthocyanin content, however strong linear correlations between total anthocyanin content and antioxidant activity, resp. wine colour density were observed. Our results also confirmed very highly significant linear relationship between wine colour density and total polyphenol content, resp. antioxidant activity and between antioxidant activity and total phenolic content.

    Full Text Available Existe uma grande dificuldade em aperfeiçoar as técnicas de manejo de formigas cortadeiras, sobretudo no que diz respeito aos sauveiros externos localizados próximos a plantios florestais. Por causa disso, o presente trabalho teve por objetivo caracterizar aspectos como tamanho e distância de sauveiros externos em plantações de eucaliptos. A avaliação foi realizada em aceiros externos de três fazendas localizadas nos municípios de João Pinheiro e Buritizeiro, em Minas Gerais, seis meses após ser realizado o combate convencional às formigas cortadeiras. Foram encontrados nove sauveiros externos, com área média de terra solta de 62,5 ± 11,1 m2, localizados a uma distância média de 33,94 ± 8,68 metros entre a margem do plantio e o local do formigueiro. Constatou-se que tais características podem ser úteis no ajuste da largura da faixa de segurança de combate, a qual deve ser igual a 50 m. O gênero Trachymyrmex e as espécies Atta laevigata e Atta sexdens rubropilosa foram registrados como ocorrências novas no município de Buritizeiro, e o gênero Acromyrmex como uma nova ocorrência nos dois municípios.

    Full Text Available Background. Hepatitis B virus (HBV infection is a well recognised occupational health hazard preventable by vaccination. Objectives. To determine the knowledge of operating room personnel (ORP in Nigeria about the Hepatitis B vaccine, their perception of Hepatitis B vaccination and vaccination status against HBV. Methods. Four university hospitals were selected by simple random sampling. A structured questionnaire was administered to 228 ORP after obtaining consent. Result. Only 26.8% of ORP were vaccinated against HBV. The primary reason for not being vaccinated or for defaulting from vaccination was lack of time. Differences in age, sex, duration of practice and respondent's institution between vaccinated and unvaccinated ORP were not significant (P>0.05. The majority (86.8% had the awareness of the existence of Hepatitis B vaccine. 83.8% of respondents believed that the vaccine should be given to the ORP as part of work place safety measures. The majority were aware of the modes of transmission of HBV infection. 78.9% of respondents believed that Hepatitis B vaccine is safe and 81.1% would recommend it to another staff. Conclusion. Despite a good knowledge about HBV infection and vaccine, most of ORP are still not vaccinated. Hepatitis B vaccination should be a prerequisite for working in the theatre, hence putting surgical patients at reduced risk.

    Full Text Available OBJECTIVE : To compare the reliability and convergent validity of instruments assessing quality of life in Brazilian older adults. METHODS : Cross-sectional study of 278 literate, community-dwelling older adults attending a municipal university for the elderly in Sao Carlos, SP, Southeastern Brazil between 2006 and 2008. The Brazilian versions of the SF-36 and WHOQOL-BREF instruments to assess quality of life were compared. Cronbach’s alpha coefficient was used to estimate reliability and Pearson’s correlation for comparison between the two scales. RESULTS : Most of participants were women (87.8% with a mean age of 63.83±7.22 years. Both scales showed an acceptable internal consistency – WHOQOL-BREF Cronbach’s alpha was 0.832 and SF-36 was 0.868. There was a weak (r ≤ 0.6 correlation between the related fields in the two questionnaires. CONCLUSIONS : The SF-36 and WHOQOL-BREF are reliable instruments for clinical and research uses in Brazilian older women. To select one, researchers should consider which aspects of quality of life they aim to capture because of weak convergent validity signs. This study’s results indicate that WHOQOL-BREF may be more relevant to evaluate changes in the quality of life of older women because it prioritizes responses to the aging process and avoids focusing on impairment.

    The crystalline silicate features are mainly reflected in infrared bands. The Spitzer Infrared Spectrograph (IRS) collected numerous spectra of various objects and provided a big database to investigate crystalline silicates in a wide range of astronomical environments. We apply the manifold ranking algorithm to perform a systematic search for the spectra with crystalline silicate features in the Spitzer IRS Enhanced Products available. In total, 868 spectra of 790 sources are found to show the features of crystalline silicates. These objects are cross-matched with the SIMBAD database as well as with the Large Sky Area Multi-object Fiber Spectroscopic Telescope (LAMOST)/DR2. The average spectrum of young stellar objects shows a variety of features dominated either by forsterite or enstatite or neither, while the average spectrum of evolved objects consistently present dominant features of forsterite in AGB, OH/IR, post-AGB, and planetary nebulae. They are identified optically as early-type stars, evolved stars, galaxies and so on. In addition, the strength of spectral features in typical silicate complexes is calculated. The results are available through CDS for the astronomical community to further study crystalline silicates.

    Full Text Available Andrographis paniculata leaf aqueous extract over 0.5, 1, 3, 5, and 24 h were determined to contain the highest amount of total phenolic compound and was used to evaluate mosquito larvicidal properties against Culex quinquefasciatus at varies concentrations (3.125, 6.25, 12.5, and 25 ppm by determining the median and 90 % lethal concentration, LC50 and LC90, respectively, within 24 h and by histological analysis. The results revealed that the total phenolic compound measurement in each time extraction were 7.97, 8.68, 7.16, 6.70, and 5.78 mg/g GAE, respectively. The one hour aqueous extract of A. paniculata leaf expressed the 24-h LC50 and LC90 values in C. quinquefasciatus which were 15.93 and 28.23 ppm, respectively. Dose dependent lesions were observed. Under histological analysis, midgut lesions, i.e., separation of the epithelial cells from the basement membrane, elongation protruding into the lumen, disruption of the brush border, and the appearance of several vesicles and cytoplasm masses were observed in this study. The present study reveals that the aqueous extract of this leaf has a suitable property for a larvicidal natural product, and may replace harmful chemical pesticides.

    In this study, reusable poly(alkoxysilane) organogels with high absorption capacities were synthesized by the condensation of a cyclo aliphatic glycol (UNOXOL™) and altering the chain length of the alkyltriethoxysilanes. The structural and thermal properties of cross-linked poly(alkoxysilane) polymers were determined by FTIR, solid-state (13)C and (29)Si CPMAS NMR and TGA. The oil absorbency of poly(alkoxysilane)s was determined through oil absorption tests, absorption and desorption kinetics. Results showed that the highest oil absorbency capacities were found to be 295% for hexane, 389% for euro diesel, 428% for crude oil, 652% for gasoline, 792% for benzene, 792% for toluene, 868% for tetrahydrofuran, and 1060% for dichloromethane for the poly(alkoxysilane) gels based on UNOXOL™ and dodecyltriethoxysilane. Owing to their hydrophobic structure, the poly(alkoxysilane) organogels can selectively absorb crude oil from water. The reusability of the absorbents was quantitatively investigated, demonstrating that absorbents can be used effectively at least nine times. PMID:26002096

    In the United States, being black, male, or growing up in a low-income and/or single-parent household have all been identified as risk factors for maladjustment during childhood. Interpretation of these findings is, however, often difficult because of the well-known associations among these variables. In the present study, we compared predictions of 3 different forms of children's competence from each of these 4 variables. In a sample of 868 black and white elementary school children from 2-parent and mother-headed 1-parent homes, we studied 3 aspects of school-based competence: conduct, peer relations, and academic achievement. Results showed that although the independent variables accounted for different amounts of variance in each domain of competence, income level and gender were better overall predictors of children's competence in conduct and peer relations than were ethnicity or household composition. Income level and ethnicity were better overall predictors of academic achievement than were gender or household composition, although each of the 4 variables made a significant contribution. Overall, income level and gender were thus the strongest predictors of children's competence. Black children were, however, more likely than white children to live in low-income homes. Our results thus highlighted some correlates of the unequal distribution of economic resources among black and white children growing up in the United States today. PMID:2344784

    The objective of this study was to perform mechanical testing on large scale heats of the advanced ODS 14YWT alloy to investigate the effects of processing parameters on mechanical properties. Mechanical properties tests were conducted on two heats of the advanced ODS 14YWT ferritic alloy: the 14YWT-SM11 was produced by extrusion at ORNL and OW4 was produced by HIP at UCSB. The 14YWT-SM11 showed very high tensile strength compared to OW4, but showed less ductility as a result. The fracture toughness transition temperature of 14YWT-SM11 was determined in two orientations and showed T{sub 0} = 48 C in the favorably strong L-T direction while shifting by 63 C to T{sub 0} = 111 C in the weaker T-L direction. The fracture toughness transition temperature for OW4 was not determined but appeared to be within the range observed for 14YWT-SM11. The fracture toughness of 14YWT-SM11 at room temperature was 86.8 MPa{radical}m and 93.1 MPa{radical}m, which was much higher than that of OW4 (27.4 MPa{radical}m). The strain rate jump tests conducted on OW4 indicated that the creep properties were similar to MA957 at 750 C.

    Congenital muscular torticollis is a common condition, but long-term neurodevelopmental follow-up is lacking. This study reports on neurodevelopmental outcome of 68 children, aged 7 to 9 years, with a history of congenital muscular torticollis, excluding children with torticollis due to other conditions. Thirty-eight children were examined for presence of neurodevelopmental disorders. Telephone interview data were available for an additional 30 children. Of those examined, 22/38 (57.9%) had or were at risk for a developmental disorder (attention-deficit hyperactivity disorder (ADHD), developmental coordination disorder, language impairment, autistic spectrum disorder) on at least 1 of the assessments administered, 23/38 (60.5%) had received developmental treatment during childhood. One child, based on a telephone interview, had a history of developmental treatment. Therefore, 30/68 (44.1%) children of the total sample demonstrated a developmental delay/disorder, currently (22/68) or previously (8/68). Our findings suggest congenital muscular torticollis to be a significant risk factor for later neurodevelopmental conditions with disorders presenting at different stages of development.

    CT colonography (CTC) is recommended after positive faecal occult blood testing (FOBt) when colonoscopy is incomplete or infeasible. We aimed to estimate the sensitivity and specificity of CTC for colorectal cancer and adenomatous polyps following positive FOBt via systematic review. The MEDLINE, EMBASE, AMED and Cochrane Library databases were searched for CTC studies reporting sensitivity and specificity for colorectal cancer and adenomatous polyps. Included subjects had tested FOBt-positive by guaiac or immunochemical methods. Per-patient detection rates were summarized via forest plots. Meta-analysis of sensitivity and specificity was conducted using a bivariate random effects model and the average operating point calculated. Of 538 articles considered, 5 met inclusion criteria, describing results from 622 patients. Research study quality was good. CTC had a high per-patient average sensitivity of 88.8 % (95 % CI 83.6 to 92.5 %) for ≥6 mm adenomas or colorectal cancer, with low between-study heterogeneity. Specificity was both more heterogeneous and lower, at an average of 75.4 % (95 % CI 58.6 to 86.8 %). Few studies have investigated CTC in FOBt-positive individuals. CTC is sensitive at a ≥6 mm threshold but specificity is lower and variable. Despite the limited data, these results suggest that CTC may adequately substitute for colonoscopy when the latter is undesirable. (orig.)

    To enhance the luminous efficacy of ultraviolet-excited white light-emitting diodes (WLEDs), a novel packaging structure that is based on a multilayered red, green, and blue (RGB) phosphor-in-glass (PiG) was proposed. The RGB PiG was prepared by screenprinting and low temperature sintering, and the effects of different configuration orders of RGB phosphor layers on the optical performance of WLEDs were studied. Compared with the conventional mixed-RGB PiG, the luminous efficacy of WLEDs packaged by the multilayered PiG with the order of R-G-B is increased by 8.2% at the driving current of 500 mA, and the corresponding correlated color temperature (CCT) and color rendering index (CRI) are 2984 K and 86.8, respectively. Moreover, the WLEDs packaged by multilayered G-R-B PiG yield the highest luminous efficacy of 27.19 lm/W at the expense of color quality, which is still an acceptable warm light, with a CCT of 3326 K and a CRI of 84.2.

    Full Text Available Background. Troponin increment is a highly sensitive and specific marker of myocardial necrosis. The reason of high troponin levels in acute stroke is not clear. The aim of this study was to identify the relationships between cardiac troponin-I (cTnI level and stroke. Methods. This study recruited 868 patients who were admitted to Istanbul Medeniyet University due to acute ischemic stroke, and the diagnosis was confirmed by diffusion magnetic resonance imaging. The patients with the causes increasing troponin level were excluded from the study. A total of 239 patients were finally included in the study. Clinics were evaluated by the modified Rankin Scale (mRS and the National Institutes of Health Stroke Scale (NIHSS. Results. Serum level of troponin was higher in ischemic stroke patients with anterior circulation involvement in comparison to posterior involvement or hemorrhagic stroke (. Higher troponin levels related to increased stroke scale scores at discharge in ischemic stroke (. The level of cTnI was correlated with stroke scale scores at both admission and discharge in posterior stroke patients (. Conclusion. cTnI is a highly specific and sensitive marker of myocardial damage, and its elevation was associated with more severe neurological deficits in acute ischemic stroke.

    [Purpose] The purpose of this study was to investigate the association between psychosocial stress, occupational stress, and musculoskeletal symptoms in Korean dental practitioners. [Subjects and Methods] Self-reported questionnaires were distributed to 401 dental practitioners in Korea. To assess the risk factors related to musculoskeletal disorders, the Nordic Musculoskeletal Questionnaire, the Korean Occupational Stress Scale, and Psychosocial Well-Being Index Short Form were used. General and work-related characteristics of the subjects consisted of seven items, including age, career, height, weight, working days/week, working hours/day, and physical strain levels. [Results] In this study, 86.8% of the practitioners experienced musculoskeletal symptoms (shoulders, 72.8%; neck, 69.3%; waist, 68.3%; wrist, 58.4%; back, 44.1%; ankle, 38.7%; knee, 36.9%; hip, 20.4%; and elbows, 9.2%). Moreover, psychosocial and occupational stress can affect the occurrence of musculoskeletal disorders. In particular, we found that psychosocial stress has significant influence on the occurrence of musculoskeletal disorders. [Conclusion] To increase the quality of life and provide high-quality medical service for dental practitioners, risk factors for musculoskeletal disorders must be managed. Accordingly, dental practitioners must maintain good posture, get an appropriate amount of rest, and perform regular stretching exercise to reduce psychological stress and improve the work environment.

Materials and Methods: The journal articles in CNKI which were included by China Academic Journal Network Publishing Database (CAJD) from 2002 to 2011 were processed with Thomson Data Analyzer (TDA). Seven aspects were analyzed: time, authors, funds for scientific research, areal distribution, institutions, authors, and keywords. Results: A total 3148 journal articles on low-dose CT examination and 7352 authors were found. The cooperative rate and degree were 63, 48% and 2.34, respectively. The famous authors were those who published more than 3 articles. Authors were from 33 areas, 471 institutions of 8 systems. Beijing and Shanghai were the most productive areas, publishing 45.9% articles. There were 10 core journals in this research area, 868 articles were funded by certain grants, and number of articles was increased yearly, indicative of the importance of grant in promoting research. Conclusion: The national low-dose CT research was in the young stage compared to the international research, and the research were not evenly distributed national wide. Though the researches have involved multi-institute, multi-system, multi-discipline, the quantities and qualities of papers still have improvement space. Strengthening basic research, improving medical ethics, and optimizing clinical research methods would promote development of low-dose CT studies. (authors)

    Full Text Available Balloon-occluded retrograde transvenous obliteration (BRTO is a highly effective therapy for gastric varices with liver cirrhosis. We have investigated the incidence of hepatocellular carcinoma (HCC after BRTO. We enrolled 71 patients with viral hepatitis in which HCC had not appeared with liver imaging findings at the time of BRTO. The overall survival rate after BRTO was 86.8%, 76.1%, and 50.5% at 1, 3, and 5 years. The occurrence rate of HCC after BRTO was 20.9%, 41.1%, and 60.7% at 1, 3, and 5 years, especially showing a higher occurrence of HCC at one year. Meanwhile, the occurrence rate of HCC after treatment which excluded BRTO for esophagogastric varices in patients was 6.3%, 19.2%, and 42.5% at 1, 3, and 5 years. The log-rank test revealed that the occurrence rate of HCC after treatment was significantly higher in the BRTO group compared with that in the non-BRTO group (P=0.0447. The recurrence rate of HCC after BRTO was 35.8% and 80.0% at 1 and 3 years. The present study demonstrated a high incidence of HCC after BRTO in liver cirrhosis patients with viral hepatitis infection. We have suggested the potential for BRTO to accelerate hepatocarcinogenesis.

    In this study, the inhibitory profiles of the prostacyclin analogues treprostinil and naxaprostene on several isolated smooth muscle preparations have been investigated. Treprostinil was an agonist for prostanoid DP1, EP2 and IP receptors, but not EP4 receptors; its DP1 potency was only 3-4 times less than PGD2 itself. Naxaprostene was much more selective for IP receptors and tended towards partial agonism. Treprostinil is a 13,14-dihydro analogue and the role of conformation around C12-15 in controlling agonist specificity is debated; the synthesis of new analogues is proposed and possible clinical usage discussed. In terms of selective prostanoid antagonists employed, BW-A868C/MK-0524 (DP1), ACA-23 (EP2) and GW-627368 (EP4) were found fit for purpose. However, the IP antagonist RO-1138452 was compromised by α1 and α2-adrenoceptor-mediated contractile activity on rat tail artery and anti-muscarinic activity on mouse trachea. There is a need for IP receptor antagonists with better selectivity and higher affinity. PMID:25542069

  2. Cell growth characterization using multi-electrode bioimpedance spectroscopy

    International Nuclear Information System (INIS)

    Cell growth characterization during culturing is an important issue in a variety of biomedical applications. In this study an electrical bioimpedance spectroscopy-based multi-electrode culture monitoring system was developed to characterize cell growth. A PC12 cell line was cultured for the cell growth study. The bioimpedance variations for PC12 cell growth within the initial 12 h were measured over a range between 1 kHz and 4 MHz at three different medium concentrations. Within this frequency range, the largest bioimpedance value was 1.9 times the smallest bioimpedance value. The phase angle decreased over the range from 1 to 10 kHz when cells were growing. Then, the phase angle approached a constant over the frequency range between 10 kHz and 2 MHz. Thereafter, the phase angle increased rapidly from 20 to 52 degrees during cell culturing between 8 and 12 h at 4 MHz. The maximum cell number after culturing for 12 h increased by 25.8% for the control sites with poly-D-lysine (PDL) pastes. For the normal growth factor, the cell number increased up to 4.78 times from 8 to 12 h, but only 0.96 and 1.60 times for the other two medium growth factors. The correlation coefficients between impedance and cell number were 0.868 (coating with PDL), and 0.836 (without PDL) for the normal concentration medium. Thus, impedance may be used as an index for cell growth characterization. (paper)

    The SSM (sputum smear microscopy) and five immunochromatographic tuberculosis antibody detection tests (DiaSpot TB, Spodex TB, SD Rapid TB, Clinotech TB Screen and Precious One-step TB) were compared for diagnosis of active TB at the Leprosy and Tuberculosis Referral Hospital, Uzuakoli, Abia State, Nigeria. Sputum specimens from 150 study participants (male/female ratio, 0.81) were cultured on Lowenstein-Jensen slopes and direct smears were stained by Ziehl-Neelsen technique and examined by light microscopy. Sera were tested for anti-TB antibodies using the rapid TB tests. A total of 91 participants were culture positive, 79 (86.8%) for M. tuberculosis and 12 (13.2%) for nontuberculous mycobacteria. The sensitivity of SSM was 50% (95% CI: 39.0-61.0) and specificity was 92.3% (95% CI: 86.4-98.2) in those culture positive for M. tuberculosis. The sensitivity and specificity of the Rapid TB tests ranged from 24.1-39.2% and 78.4-87.8%, respectively. None of the five rapid TB tests had acceptable level of accuracy for diagnosis of active TB. The sensitivity of SSM though moderate is inadequate for long term TB control in this setting.

    Trimethylolpropane triesters are biodegradable synthetic lubricant base oil alternative to mineral oils, polyalphaolefins and diesters. These oils can be produced from trimethylolpropane (TMP) and fatty acid methyl esters via chemical or enzymatic catalyzed synthesis methods. In the present study, a commercial palm oil derived winter grade biodiesel (ME18) was evaluated as a viable and sustainable methyl ester source for the synthesis of high oleic trimethylolpropane triesters (HO-TMPTE). ME18 has fatty acid profile containing 86.8% oleic acid, 8.7% linoleic acid with the remaining minor concentration of palmitic acid, stearic acid and linolenic acid. It's high oleic property makes it superior to produce synthetic lubricant base oil that fulfills both the good low temperature property as well as good oxidative stability. The synthetic base oil produced had a viscosity of 44.3 mm(2)/s at 40°C meeting the needs for ISO 46 oils. It also exhibited an excellent viscosity index of 219 that is higher than some other commercial brands of trimethylolpropane trioleate. Properties of base oil such as cloud point, density, acid value, demulsibility and soap content were also examined. The oil was then used in the formulation of tapping oil and appraised in term of adaptability, stability and field test performance. PMID:25748374

    Use of performance-enhancing drugs (PEDs) is common among strength-trained individuals, and a growing concern is the misuse of insulin. A 99-item Internet-based survey was posted on discussion boards of various fitness, bodybuilding, weightlifting, and anabolic steroid Web sites between February and June 2009. A case series of 41 nondiabetic insulin users is described. The typical insulin user was 30.7 ± 9.2 years old, male (97.6%), and Caucasian/white (86.8%) who classified himself as a "recreational exerciser" (47.5%). The average insulin user also used anabolic steroids (95.1%) and practiced polypharmacy by incorporating 16.2 ± 5.6 PEDs in his or her yearly routine. Hypoglycemia was reported by most of the subjects (56.8%), and one individual reported unconsciousness. Insulin was obtained most commonly from local sources (e.g., friends, training partners, gym member/dealer; 40.5%) and community pharmacies (37.8%), with most (80.6%) finding it "easy" to acquire their insulin. Strategies aimed to prevent insulin misuse are needed. PMID:22777326

  6. Survey of breast cancer screening by mammography. Results of a questionnaire sent to local self-governing bodies

    International Nuclear Information System (INIS)

    In order to grasp the current status of breast cancer screening in Japan, a questionnaire was distributed to all local self-governing bodies (LSGB). The results indicated that breast cancer screening with mammography was performed by 97.9% of LSGB. Breast cancer screening was started for women aged less than 40 years at 11.9% of the LSGB, and from 40 years of age at 86.8%. Breast cancer screening for women aged 30-39 years was performed at 51.2% of the LSGB. The proportions of studies involving palpation, mammography, and ultrasonography (US) were 34.0%, 24.5%, and 41.6%, respectively. The coverage of screening invitations between April 2006 and March 2007 was grasped at 94.7% of LSGB. At 23.2%, the coverage was less than 10%, and at 33.8% was 10-19.9%. At 7.1%, the coverage was 50% or more. The national average for coverage was 10%, and was especially low in large cities. The recall rate for LSBG between April 2006 and March 2007 was 85.2%. At 22.4% of the LSBG, recall rates were less than 5%, and at 15.6% the recall rates were 50% or more. Screening mammography for women aged 30-39 years needs to be examined in the future. When recall rates exceed 20%, it is necessary to re-examine the accuracy management of breast cancer screening. (author)

    For palliative care of spinal bone metastases, stability assessment is of crucial importance. Pathological fractures, instability-related patient immobility and the extent of bone metastasis have been reported to affect patient outcome and these parameters have therefore been used for treatment stratification. We report on stability-dependent fracture and survival rates in over 300 non-small cell lung cancer (NSCLC) patients. Data from 303 patients with 868 osteolytic metastases treated with radiotherapy (RT) between 2000 and 2012 were evaluated retrospectively. In NSCLC patients with bone metastases only, the retrospective 6- and 12-month overall survival (OS) rates were 76.7 and 47.2%, respectively. In patients with additional non-bone distant metastases, these values were 60.0 and 34.0%, respectively. Survival rates were significantly lower in patients with multiple bone metastases and in those suffering pathological fractures (p=0.017). No significant impact of histological type, location of spinal lesions or treatment regime was detected. Furthermore, stability assessment revealed no influence of vertebral column stability on patient outcome (p=0.739). Our analysis demonstrated a correlation between the pathological fractures of bone lesions, the number of bone metastases, additional distant metastases and survival. The results offer a rationale for future prospective investigations. (orig.)

  8. A study about the possible mining and benefit of the uranium ores of the ''Las Margaritas'' deposit, in Sierra de Pena Blanca, municipality of Villa Aldama, State of Chihuahua, Mexico

    International Nuclear Information System (INIS)

    Considering all the characteristics of the deposit as well as its location in relation to the others, the necessary personnel, the extraction yield the structural conditions, etc. we can say that an advisable method of exploitation is the open pit method because in that way we can resolve a great number of problems, principally the high radiation to which the personnel would be exposed in a subterraneous work. The deposit reserves are 1,221,868 tons of ore with an average of 880 grams of U3O8 per ton. During the exploitation at open pit 1,147,025 tons will be extracted and through subterraneous work other 50,406 tons will be recuperated. The exploitation will cost $84.00 Mexican currency per ton. According to the experimental studies about the mineral which will be treated it has been concluded that the conventional acid leaching is the appropriate treatment to be followed since the recoveries were of 88 to 95%. However, it is suggested to make more studies about the metallurgical aspect and industrial engineering studies in order to lower costs, since these are theoretical and can be improved in the practice.

    Full Text Available Plum is a globally grown stone fruit and can be divided into several species. In particular, the Prunus salicina, which is native to China, is widely grown in many fruit orchards in Korea and Japan, as well as the United States and Australia. The transcriptome data for Prunus salicina has not been reported to our knowledge. In this study, we performed de novo transcriptome assembly for two selected P. salicina cultivars referred to as Akihime and Formosa (commercially important plum cultivars in Korea using next generation sequencing. We obtained a total of 9.04 GB and 8.68 GB raw data from Akihime and Formosa, respectively. De novo transcriptome assembly using Trinity revealed 155,169 and 160,186 transcripts for Akihime and Formosa. Next, we identified 121,278 and 116,544 proteins from Akihime and Formosa using TransDecoder. We performed BLASTP against the NCBI non-redundant (nr dataset to annotate proteins. Taken together, this is the first transcriptome data for P. salicina to our knowledge.

    Full Text Available This study explores a method to classify seven tropical rainforest tree species from full-range (400–2,500 nm hyperspectral data acquired at tissue (leaf and bark, pixel and crown scales using laboratory and airborne sensors. Metrics that respond to vegetation chemistry and structure were derived using narrowband indices, derivative- and absorption-based techniques, and spectral mixture analysis. We then used the Random Forests tree-based classifier to discriminate species with minimally-correlated, importance-ranked metrics. At all scales, best overall accuracies were achieved with metrics derived from all four techniques and that targeted chemical and structural properties across the visible to shortwave infrared spectrum (400–2500 nm. For tissue spectra, overall accuracies were 86.8% for leaves, 74.2% for bark, and 84.9% for leaves plus bark. Variation in tissue metrics was best explained by an axis of red absorption related to photosynthetic leaves and an axis distinguishing bark water and other chemical absorption features. Overall accuracies for individual tree crowns were 71.5% for pixel spectra, 70.6% crown-mean spectra, and 87.4% for a pixel-majority technique. At pixel and crown scales, tree structure and phenology at the time of image acquisition were important factors that determined species spectral separability.

    Prolyl endopeptidase (PEP) has been associated with neurodegenerative disorders, and the PEP inhibitors can restore the memory loss caused by amnesic compounds. In this study, we investigated the PEP inhibitory activity of the enzymatic hydrolysates from various food protein sources, and isolated and identified the PEP inhibitory peptides. The hydrolysate obtained from sodium caseinate using bromelain (SC/BML) displayed the highest inhibitory activity of 86.8% at 5 mg mL(-1) in the present study, and its IC50 value against PEP was 0.77 mg mL(-1). The F-5 fraction by RP-HPLC (reversed-phase high performance liquid chromatography) from SC/BML showed the highest PEP inhibition rate of 88.4%, and 9 peptide sequences were identified. The synthetic peptides (1245.63-1787.94 Da) showed dose-dependent inhibition effects on PEP as competitive inhibitors with IC50 values between 29.8 and 650.5 μM. The results suggest that the peptides derived from sodium caseinate have the potential to be PEP inhibitors. PMID:26574880

    To evaluate the diagnostic accuracy of occlusal and proximal caries detection using CCD, CMOS, PSP and film system. 32 occlusal and 30 proximal tooth surfaces were radiographed under standardized conditions using 3 digital systems; CCD (CDX-2000HQ, Biomedysis Co., Seoul, Korea), CMOS (Schick, Schick Inc., Long Island, USA), PSP (Digora FMX, Orion Co./Soredex, Helsinki, Finland) and 1 film system (Kodak Insight, Eastman Kodak, Rochester, USA). 5 observers examined the radiographs for occlusal and proximal caries using a 5-point confidence scale. The presence of caries was validated histologically and radiographically. Diagnostic accuracy was evaluated using ROC curve areas (AZ). Analysis using ROC curves revealed the area under each curve which indicated a diagnostic accuracy. For occlusal caries, Kodak Insight film had an Az of 0.765, CCD one of 0.730, CMOS one of 0.742 and PSP one of 0.735. For proximal caries, Kodak Insight film had an Az of 0.833, CCD one of 0.832, CMOS one of 0.828 and PSP one of 0.868. No statistically significant difference was noted between any of the imaging modalities. CCD, CMOS, PSP and film performed equally well in the detection of occlusal and proximal dental caries. CCD, CMOS and PSP-based digital images provided a level of diagnostic performance comparable to Kodak Insight film.

    2011-12-01

    With a sample of Italians selected from 71 Italian counties (N = 1,868), we performed two multilevel analyses aimed at predicting the perceived risk of crime at local (i.e., in the participants' county of residence) and at societal (i.e., in the context of Italian society) levels. A significant proportion of the variation in local risk perception was at the county level. The following individual variables predicted higher levels of this variable: indirect victimization, the perception of social and physical disorder, being a woman, being poorly educated, and being an older person. Among the ecological predictors, the crime rate and unemployment rate predicted higher levels of local crime risk perception, while the immigrant rate did not. Perceived risk of crime at the societal level did not show significant variation at the county level. Education, being a man, trusting people, and adhesion to post-materialistic values predicted lower levels of societal crime risk perception, while number of sons/daughters and exposure to television news increased it. The limitations and possible development of this study are discussed. PMID:21161721

  15. I131 application method in mutual feeding tests on honey bees (Apis mellifica L.)

    International Nuclear Information System (INIS)

    In order to avoid outward contamination with tracers it is necessary to check the bee's external radioactivity and not to use externally radioactive animals for experiments. For radioactive feeding and sorting out of contaminated bees a method is being suggested which enables to achieve only 0.6% of the radioactivity of the whole bee's body on the feet. This contamination of the bee's body surface is of no practical importance while investigating mutual feeding in the insects of the given species. Bees fed with radioactive feed did not belch it while being mortified in the refrigerator at 0 deg C, but belched it under chloroform. In the bee's body I131 is distributed in the following way: in the head - 3.6, in the chest -8.1, in the abdomen - 86.8, in the feet - 0.7 and in the wings - 0.2% on the average. These amounts change with time: they increase in some parts of the body, while decrease in some other

  16. Mercury in United Kingdom topsoils; concentrations, pools, and Critical Limit exceedances

    International Nuclear Information System (INIS)

    The median total mercury concentration in 898 UK rural topsoils, sampled between 1998 and 2008, was 0.095 μg g-1. Approximate adjustment for unreactive metal produced an estimate of 0.052 μg g-1 for reactive Hg. The highest concentrations were in the north and west, where organic-rich soils with low bulk densities dominate, but the spatial pattern was quite different if soil Hg pools (mg m-2) were considered, the highest values being near to the industrial north of England and London. Possible toxic effects of Hg were best evaluated by comparison with soil Critical Limits expressed as ratios of Hg to soil organic matter, or soil solution Hg2+ concentrations, estimated by chemical speciation modelling. Only a few percent of the rural UK soils showed exceedance, and this also applied to rural soils from the whole of Europe. UK urban and industrial soils had higher Hg concentrations and more cases of exceedance. - Highlights: → Concentrations of Hg in rural soils are highest near to industrial areas and London. → Mercury is strongly associated with soil organic matter. → Only a few percent of UK rural soils have Hg levels higher than Critical Limits. → Critical Limit exceedances are found for 15-30% of urban and industrial soils. - Mercury contents of 898 UK and 868 European rural soils are largely lower than Critical Limit values, but appreciable numbers of soils in UK urban and industrial areas show exceedance.

  17. A reconfigurable multi-mode multi-band transmitter with integrated frequency synthesizer for short-range wireless communication

    International Nuclear Information System (INIS)

    A reconfigurable multi-mode direct-conversion transmitter (TX) with integrated frequency synthesizer (FS) is presented. The TX as well as the FS is designed with a flexible architecture and frequency plan, which helps to support all the 433/868/915 MHz ISM band signals, with the reconfigurable bandwidth from 250 kHz to 2 MHz. In order to save power and chip area, only one 1.8 GHz VCO is adopted to cover the whole frequency range. All the operation modes can be regulated in real time by configuring the integrated register-bank through an SPI interface. Implemented in 180 nm CMOS, the FS achieves a frequency coverage of 320–460 MHz and 620–920 MHz. The lowest phase noise can be −107 dBc/Hz at a 100 kHz offset and −126 dBc/Hz at a 1 MHz offset. The transmitter features a + 10.2 dBm peak output power with a +9.5 dBm 1-dB-compression point and 250 kHz/500 kHz/1 MHz/2 MHz reconfigurable signal bandwidth. (semiconductor integrated circuits)

    A study was undertaken to assess the safety and efficacy of LASIK with the LADARVision laser by Autonomous Technologies, (Orlando, FL). The study included four subsets: Spherical myopia -- up to -11.00D, spherical hyperopia -- up to +6.00D. Both myopic and hyperopic astigmatism could be corrected, up to 6.00D of astigmatism. A total of 105 patients participated. Sixty-six patients were myopic and 39 were hyperopic. The mean (+/- SD) age was 42.8 +/- 9.3 years for myopia and 53.2 +/- 9.9 years for hyperopia. At 3 months postop. Sixty-one myopic eyes were available for evaluation. Uncorrected visual acuity was 20/20 in 70% of eyes and 20/40 in 92.9% of all eyes. The refractive outcome was within +/- 0.50D in 73.8% of eyes and within +/- 1.00D in 96.7 of eyes. Thirty-eight hyperopic eyes were available. Uncorrected visual acuity was 20/20 in 42.1% of eyes and 20/40 in 88% of all eyes. The refractive outcome was within +/- 0.50D in 57.9% of eyes and within +/- 1.00D in 86.8% of eyes. Complications were not sight threatening and were discussed in detail. Lasik with the LADARVision laser appears to be safe and effective.

The maximum gold adsorption capacity of wood shaving fly ash washed with tap water (WSFW) at 20, 30, 40, and 60 degrees C was 8.68, 7.79, 7.44, and 7.25 mg(Au)/g(adsorbent), respectively, while of activated carbon it was 76.78, 60.95, 56.13, and 51.90 mg(Au)/g(adsorbent), respectively. Deionized water at 100 degrees C could elute gold adsorbed onto WSFW to 71%. The effect of the increasing temperature of water, 30, 60, and 100 degrees C, implied that the adsorption mechanism was mainly physical adsorption. The negative values of enthalpy change (DeltaH) and free energy change (DeltaG) indicated an exothermic and spontaneous process, respectively. The positive values of entropy change (DeltaS) indicated increasing disorder of the system. The advantages of wood shaving fly ash are the purification of gold and the easier recycling of gold from the gold-adsorbed adsorbent. PMID:15925603

    A series of neutral hexacoordinated nickel(II) complexes of formula [NiII (L)X2] (where L = 3,4-bis(2-pyridylmethylthio)toluene with tetradentate N2S2 donor set and X = chloride (1), azide (2), cyanate (3) and isothiocyanate anion (4)) have been synthesized and isolated in pure form. The complexes were characterized by physicochemical and spectroscopic methods along with detailed structural characterization of 1,2 and 3 by single crystal X-ray diffraction analyses. The structural study showed that the nickel(II) ion has a distorted octahedral geometry being chelated by the tetradentate N2S2 ligand and bound to cis- located choride or pseudohalide anions. In dimethylformamide solution the complexes showed quasi-reversible NiII/NiIII redox couples in cyclic voltammograms with E1/2 values of +0.723, +0.749, +0.768 and +0.868 V for 1, 2, 3 and 4, respectively. The study of interaction of the complexes with calf thymus DNA, bovine serum albumin (BSA) and human serum albumin (HSA) using spectroscopic and physicochemical tools clearly indicates that the complexes interact with DNA via groove binding mode.

    In order to screen lignocellulose-degrading superior mushroom strains ten strains of mushrooms (Lentinus edodes939, Pholiota nameko, Lentinus edodes868, Coprinus comatus, Macrolepiota procera, Auricularia auricula, Hericium erinaceus, Grifola frondosa, Pleurotus nebrodensis, and Shiraia bambusicola) were inoculated onto carboxymethylcellulose agar-Congo red plates to evaluate their ability to produce carbomethyl cellulase (CMCase). The results showed that the ratio of transparent circle to mycelium circle of Hericium erinaceus was 8.16 (P < 0.01) higher than other strains. The filter paper culture screening test showed that Hericium erinaceus and Macrolepiota procera grew well and showed extreme decomposition of the filter paper. When cultivated in guaiacol culture medium to detect their abilities to secrete laccase, Hericium erinaceus showed the highest ability with the largest reddish brown circles of 4.330 cm. CMCase activity determination indicated that Coprinus comatus and Hericium erinaceus had the ability to produce CMCase with 33.92 U/L on the 9th day and 22.58 U/L on the 10th day, respectively, while Coprinus comatus and Pleurotus nebrodensis had the ability to produce laccase with 496.67 U/L and 489.17 U/L on the 16th day and 18th day. Based on the results, Coprinus comatus might be the most promising lignocellulose-degrading strain to produce both CMCase and laccase at high levels. PMID:24693246

    Full Text Available In the present investigation, we successfully fabricate a hybrid polymer nanocomposite containing epoxy/polyester blend resin and graphene nanoplatelets (GNPs by a novel technique. A high intensity ultrasonicator is used to obtain a homogeneous mixture of epoxy/polyester resin and graphene nanoplatelets. This mixture is then mixed with a hardener using a high-speed mechanical stirrer. The trapped air and reaction volatiles are removed from the mixture using high vacuum. The hot press casting method is used to make the nanocomposite specimens. Tensile tests, dynamic mechanical analysis (DMA and thermogravimetric analysis (TGA are performed on neat, 0.2 wt %, 0.5 wt %, 1 wt %, 1.5 wt % and 2 wt % GNP-reinforced epoxy/polyester blend resin to investigate the reinforcement effect on the thermal and mechanical properties of the nanocomposites. The results of this research indicate that the tensile strength of the novel nanocomposite material increases to 86.8% with the addition of a ratio of graphene nanoplatelets as low as 0.2 wt %. DMA results indicate that the 1 wt % GNP-reinforced epoxy/polyester nanocomposite possesses the highest storage modulus and glass transition temperature (Tg, as compared to neat epoxy/polyester or the other nanocomposite specimens. In addition, TGA results verify thethermal stability of the experimental specimens, regardless of the weight percentage of GNPs.

    Full Text Available Training needs of teachers in Information and Communication Technologies (ICT is one of the key aspects for the integration of ICT in daily educational practice, along with competences in ICT and the use of these technological resources by teachers. The aim of this paper is to establish teacher training profiles and relate them to their competences in ICT and the use thereof, together with personal and contextual factors. To this end, it has been used a survey design, with the sample 868 teachers from primary and secondary education in the Comunidad Valenciana. The instrument for collecting information is a questionnaire. The results indicate that teachers demand higher-level training in personal-professional plane, requiring more training on the planes with the students in the classroom and the integration of ICT in the classroom. Furthermore, these needs can be structured into four profiles: initial, initial-intermediate, intermediate and advanced. It has also found a clear relationship between these profiles of training needs in competences in ICT, especially technology; the use of ICT, principally in personal-professional plan. It is also found an influence on these profiles of teachers of the age and the frequency of computer use. This implies that educational administrations should consider these results in the development of teacher training plans to produce higher quality programs, as it is demanded since different fields.

  10. Long-term trends of 137Cs concentrations in marine biota, sediments and seawater in the coastal seas in the vicinity of nuclear power plants in Japan

    International Nuclear Information System (INIS)

    The results of the long-term trend analyses of the 137Cs data obtained during the marine environmental radioactivity monitoring program sponsored by the Ministry of Education, Culture, Sports, Science and Technology and carried out from 1983 to 2000 by the Marine Ecology Research Institute are presented. In 86.8% of the marine biota, 75.6% of the sediments, 100% of the surface seawater and 91.1% of the bottom seawater, a statistically significant decrease of 137Cs concentrations was observed. The 137Cs concentrations in the bottom seawater and sediments below the depth of 200 m decreased more slowly than those above the 200 m depth. The 137Cs concentrations in the marine biota, surface seawater, and bottom seawater and sediments above 200 m decreased by similar annual rates of 0.039, 0.041, 0.045 and 0.041 year-1, respectively. Those of the bottom seawater and sediments below the 200 m depth (200∼500 m) decreased by the rates of 0.025 and 0.026 year-1, respectively. These results suggest that an equilibrium in 137Cs concentrations in the seawater and sediments, including the marine biota above the 200 m depth, is attained both above and below the depth of 200 m.

    There is evidence that immune-inflammatory, stress of reactive oxygen and nitrogen species (IO&NS) processes play a role in the neurodegenerative processes observed in Parkinson's disease (PD). The aim of the present study was to investigate peripheral IO&NS biomarkers in PD. We included 56 healthy individuals and 56 PD patients divided in two groups: early PD stage and late PD stage. Plasma lipid hydroperoxides (LOOH), malondialdehyde (MDA), nitric oxide metabolites (NOx), sulfhydryl (SH) groups, catalase (CAT) activity, superoxide dismutase (SOD) activity, paraoxonase (PON)1 activity, total radical trapping antioxidant parameter (TRAP) and C-reactive protein (CRP) were measured. PD is characterized by increased LOOH, MDA and SOD activity and lowered CAT activity. A combination of five O&NS biomarkers highly significantly predicts PD with a sensitivity of 94.5% and a specificity of 86.8% (i.e., MDA, SOD activity, TRAP, SH-groups and CAT activity). The single best biomarker of PD is MDA, while LOOH and SOD activity are significantly associated with late PD stage, but not early PD stage. Antiparkinson drugs did not affect O&NS biomarkers, but levodopa+carbidopa significantly increased CRP. It is suggested that MDA may serve as a disease biomarker, while LOOH and SOD activity are associated with late PD stage characteristic. New treatments for PD should not only target dopamine but also lipid peroxidation. PMID:26861200

    By using density functional theory, we studied the interaction process between barbital and 2-vinyl-4,6-diamino-1,3,5-triazine in acetonitrile at 333 K. Barbital and 2-vinyl-4,6-diamino-1,3,5-triazine were used as the template and functional monomer, respectively. The molecularly imprinted polymer microspheres containing barbital and 2-vinyl-4,6-diamino-1,3,5-triazine were synthesized through precipitation polymerization. After removing the template molecule barbital, the average diameter of the obtained molecularly imprinted polymers was 1.45 μm. By optimizing the molar ratio of barbital and the 2-vinyl-4,6-diamino-1,3,5-triazine, the resulting molecularly imprinted polymers showed the highest adsorption for the barbital. The analysis of the Scatchard plot revealed that the dissociation constant (Kd ) and apparent maximum adsorption quantity (Qmax ) of the molecularly imprinted polymers were 30.69 mg/L and 8.68 mg/g, respectively. The study of selective adsorption showed that molecularly imprinted polymers exhibited higher selectivity for barbtital than that for 1,3-dimethyl barbituric acid and pentobarbital. Herein, the studies can provide theoretical and experimental references for the barbital-imprinted system. PMID:26420630

    Immune traits play pivotal roles in animal immune capacity development and disease resistance. Single nucleotide polymorphisms (SNPs) are common forms of genetic variations among individuals, which are thought to account for the majority of inherited phenotypic variations. In this study, we performed genomewide association, using the Illumina 60K SNP BeadChip studies to detect molecular markers and candidate genes associated with immune traits in an F2 population. Sixteen immune traits were measured. We identified 85 significant SNPs (p chicken chromosome 1 (GGA1). A candidate region relevant to haematological traits from GLM was found in GGA4 and 9 loci were located on it. Three loci (GGaluGA348521, Gga_rs16098446 and GGaluGA348518) within 179 kb (16 286 868-16 466 134 bp) on GGAZ from GLM provided evidence that this genomic segment may be relevant to red blood cell volume distribution width (RDW). Our study provides a list of significant SNPs and candidate genes that will be valuable information for unveiling the underlying molecular mechanism of immune regulation. PMID:26853217

    To investigate the evolution of metal-enriched gas over recent cosmic epochs as well as to characterize the diffuse, ionized, metal-enriched circumgalactic medium, we have conducted a blind survey for C iv absorption systems in 89 QSO sightlines observed with the Hubble Space Telescope Cosmic Origins Spectrograph. We have identified 42 absorbers at z critical density of the universe (ΩC iv = 10.0 ± 1.5 × 10-8) from z ˜ 1.5 to the present epoch, consistent with predictions from cosmological hydrodynamical simulations. Furthermore, the data support a functional form for the column density distribution function that deviates from a single power law, also consistent with independent theoretical predictions. As the data also probe heavy element ions in addition to C iv at the same redshifts, we identify, measure, and search for correlations between column densities of these species where components appear to be aligned in velocity. Among these ion-ion correlations, we find evidence for tight correlations between C ii and Si ii, C ii and Si iii, and C iv and Si iv, suggesting that these pairs of species arise in similar ionization conditions. However, the evidence for correlations decreases as the difference in ionization potential increases. Finally, when controlling for observational bias, we find only marginal evidence for a correlation (86.8% likelihood) between the Doppler line width b(C iv) and column density N(C iv).

  17. Lifetime risk of stroke and impact of hypertension. Estimates from the adult health study in Hiroshima and Nagasaki

    International Nuclear Information System (INIS)

    Very few reports have been published on lifetime risk (LTR) of stroke by blood pressure (BP) group. This study included participants in the Radiation Effects Research Foundation Adult Health Study who have been followed up by biennial health examinations since 1958. We calculated the LTR of stroke for various BP-based groups among 7847 subjects who had not been diagnosed with stroke before the index age of 55 years using cumulative incidence analysis adjusting for competing risks. By 2003, 868 subjects had suffered stroke (512 (58.9%) were women and 542 (62.4%) experienced ischemic stroke). BP was a significant factor in determining risk of stroke for men and women, with distributions of cumulative risk for stroke significantly different across BP groups. The LTR of all-stroke for normotension (systolic BP/diastolic BP 160/100 mm Hg) were 13.8-16.9-25.8-25.8% in men and 16.0-19.9-24.0-30.5% in women, respectively (P140/90 mm Hg) at any of the index ages of 45, 55, 65 and 75 years.

    Tannery residues and coal mine waste are heavily polluting sources in Brazil, mainly in the Southern States of Rio Grande do Sul and Santa Catarina. In order to study the effects of residues of chrome leather tanning (sludge and leather shavings) and coal waste on soybean and maize crops, a field experiment is in progress since 1996, at the Federal University of Rio Grande do Sul Experimental Station, county of Eldorado do Sul, Brazil. The residues were applied twice (growing seasons 1996/97 and 1999/00). The amounts of tannery residues were applied according to their neutralizing value, at rates of up to 86.8 t ha{sup -1}, supplying from 671 to 1.342 kg ha{sup -1} Cr(III); coal waste was applied at a total rate of 164 t ha{sup -1}. Crop yield and dry matter production were evaluated, as well as the nutrients (N, P, K, Ca, Mg, Cu and Zn) and Cr contents. Crop yields with tannery sludge application were similar to those obtained with N and lime supplied with mineral amendments. Plant Cr absorption did not increase significantly with the residue application. Tannery sludge can be used also to neutralize the high acidity developed in the soil by coal mine waste.

    Tomato plants (Lycopersicon esculentum) are highly susceptible to phytopathogen attack. The resulting intensive application of pesticides on tomato crops can affect the environment and health of humans and animals. The objective of this study was to select potential biocontrol agents among actinobacteria from tomato plants, in a search for alternative phytopathogen control. We evaluated 70 endophytic actinobacteria isolated from tomato plants in southern Brazil, testing their antimicrobial activity, siderophore production, indoleacetic acid production, and phosphate solubility. The actinomycete isolate with the highest antimicrobial potential was selected using the agar-well diffusion method, in order to optimize conditions for the production of compounds with antimicrobial activity. For this study, six growth media (starch casein-SC, ISP2, Bennett's, Sahin, Czapek-Dox, and TSB), three temperatures (25 degrees C, 30 degrees C, and 35 degrees C) and different pH were tested. Of the actinobacteria tested, 88.6% showed antimicrobial activity against at least one phytopathogen, 72.1% showed a positive reaction for indoleacetic acid production, 86.8% produced siderophores and 16.2% showed a positive reaction for phosphate solubility. Isolate R18(6) was selected due to its antagonistic activity against all phytopathogenic microorganisms tested in this study. The best conditions for production were observed in the SC medium, at 30 degrees C and pH 7.0. The isolate R18(6) showed close biochemical and genetic similarity to Streptomyces pluricolorescens.

    Molasses spentwash from distilleries is characterized by high COD and colour. The fungal decolourization of anaerobically digested molasses spentwash requires significant dilution. In this study, decolourization by Aspergillus niger isolate IITB-V8 was performed on polyaluminium chloride (PAC) treated anaerobically digested spentwash without dilution of wastewater. Optimization of parameters was studied using statistical experimental designs. In the first step, Plackett-Burman design was used for screening the important parameters. Glucose was taken as the carbon source for the growth of A. niger. KH(2)PO(4) and pH were found to be the important factors affecting decolourization. In the second step, Box-Behnken design was used to determine the optimum level of each of the significant parameters. A second-order polynomial was determined by the multiple regression analysis of the experimental data. The optimum values for the important factors to achieve maximum decolourization of 68.4% were 5.5 g/L Glucose, 1.2 g/L KH(2)PO(4) and 5 pH. The determination coefficient (R(2)) was 0.9973, which ensures adequate credibility of the model. The total decolourization obtained after fungal treatment was 86.8% which indicates fungal decolourization after pretreatment with PAC is a viable option for the treatment of digested molasses spentwash.

    Beijing B0/W148, a "successful" clone of Mycobacterium tuberculosis, is widespread in the Russian Federation and some countries of the former Soviet Union. Here, we used label-free gel-LC-MS/MS shotgun proteomics to discover features of Beijing B0/W148 strains that could explain their success. Qualitative and quantitative proteome analyses of Beijing B0/W148 strains allowed us to identify 1,868 proteins, including 266 that were differentially abundant compared with the control strain H37Rv. To predict the biological effects of the observed differences in protein abundances, we performed Gene Ontology analysis together with analysis of protein-DNA interactions using a gene regulatory network. Our results demonstrate that Beijing B0/W148 strains have increased levels of enzymes responsible for long-chain fatty acid biosynthesis, along with a coincident decrease in the abundance of proteins responsible for their degradation. Together with high levels of HsaA (Rv3570c) protein, involved in steroid degradation, these findings provide a possible explanation for the increased transmissibility of Beijing B0/W148 strains and their survival in host macrophages. Among other, we confirmed a very low level of the SseA (Rv3283) protein in Beijing B0/W148 characteristic for all «modern» Beijing strains, which could lead to increased DNA oxidative damage, accumulation of mutations, and potentially facilitate the development of drug resistance.

    Purpose: To describe the particular disc displacement pattern seen at MRI in patients with spondylolisthesis, and its potential contribution to foraminal stenosis. Methods: 38 patients with symptomatic lumbar anterior spondylolisthesis and 38 sex and aged matched control patients with herniated disc disease, at corresponding disc space levels, were included for study. In each case note was made of the presence, absence and direction of disc displacement and also the presence and location of neural contact with the displaced disc. Results: In 33 of 38 (86.8%) patients in the spondylolisthesis group, the vertical disc displacement was upward. In the control group only 3 patients (7.8%) had upward vertical disc displacement. 19 patients (53%) from the spondylolisthesis group had exit foraminal nerve root contact, compared to 7 patients (18.4%) from the control group. 27 control patients (71%) had contact within the lateral recess, compared to only 6 patients (17%) with spondylolisthesis. Differences for upward displacement were significant (p < 0.05). Conclusion: Disc displacement in patients with spondylolisthesis is predominately in a cephalad and lateral direction. Although this disc displacement pattern can occur in patients without spondylolisthesis, its incidence is much greater in the subset of patients with concomitant spondylolisthesis. In the setting of acquired osseous narrowing of the exit foramen, this described pattern of disc displacement superiorly and laterally in spondylolisthesis increases the susceptibility of spondylolisthesis patients to radicular symptoms and accounts for the exiting nerve root being more commonly affected than the traversing nerve root.

    Full Text Available In this paper, analytical modeling of passive rectifying circuits and the harvesting of electromagnetic (EM power from intentionally generated as well as from ubiquitous sources are presented. The presented model is based on the linearization of rectifying circuits. The model provides an accurate method of determining the output characteristics of rectifying circuits. The model was verified with Advance Design System (ADS Harmonic balance (HB simulations and measurements. The results from the presented model were in agreement with simulations and measurements. Consequently design considerations and trade-off of radio frequency (RF harvesters are discussed. To verify the exploitation of ambient RF power sources for operation of sensors, a dual-band antenna with a size of ~λ/4 at 900MHz and a passive dual-band rectifier that is able to power a commercial Thermo-Hygrometer requiring ~1.3V and 0.5MΩ from a global system for mobile communications (GSM base station is demonstrated. The RF power delivered by the receiving dual-band antenna at a distance of about 110 m from the GSM base station ranges from -27 dBm to -50 dBm from the various GSM frequency bands. Additionally, wireless range measurements of the RF harvesters in the industrial, scientific and medical (ISM band 868MHz is presented at indoor conditions.

  4. Crystallization and preliminary crystallographic analysis of the tetrameric form of phosphofructokinase-2 from Escherichia coli, a member of the ribokinase family

    International Nuclear Information System (INIS)

    The phosphofructokinase-2 enzyme from E. coli was crystallized in its tetrameric inhibited form. This is the only member of the ribokinase family known to suffer a transition from dimer to tetramer in response to the allosteric binding of MgATP. Escherichia coli contains two phosphofructokinases, Pfk-1 and Pfk-2, which belong to unrelated protein families. In addition to catalytic function, the enzymes have converged in showing substrate inhibition by the nucleotide MgATP. However, although both Pfk-1 and Pfk-2 have been extensively characterized biochemically, only the structure of the former has been solved by X-ray diffraction. In order to fully understand how the same function has evolved on different structural folds, Pfk-2 has been crystallized by the hanging-drop vapour-diffusion method using PEG 6000 as precipitant. Single crystals were grown in the presence of MgATP and diffracted to 1.98 Å. The crystals belong to the orthorhombic system, space group P2221, with unit-cell parameters a = 42.8, b = 86.8, c = 171.3 Å. The calculated Matthews coefficient of 2.45 Å3 Da−1 indicates the presence of two monomers in the asymmetric unit, corresponding to a solvent content of 49%. Structure determination is ongoing

    Full Text Available Water-soluble polymers are known to be used in chemically enhanced oil recovery (EOR processes, but their applications are limited in high-temperature and high-salinity oil reservoirs because of their inherent poor salt tolerance and weak thermal stability. Hydrophobic association of partially hydrolyzed polyacryamide (HAHPAM complexed with silica nanoparticles to prepare nano-hybrids is reported in this work. The rheological and enhanced oil recovery (EOR properties of such hybrids were studied in comparison with HAHPAM under simulated high-temperature and high-salinity oil reservoir conditions (T: 85 °C; total dissolved solids: 32,868 mg∙L−1; [Ca2+] + [Mg2+]: 873 mg∙L−1. It was found that the apparent viscosity and elastic modulus of HAHPAM solutions increased with addition of silica nanoparticles, and HAHPAM/silica hybrids exhibit better shear resistance and long-term thermal stability than HAHPAM in synthetic brine. Moreover, core flooding tests show that HAHPAM/silica hybrid has a higher oil recovery factor than HAHPAM solution.

    Full Text Available To reduce the radar cross section of a waveguide slot antenna, a three-layer metamaterial is presented based on orthogonal double split-ring resonators. The absorption characteristics of three-layer metamaterial are demonstrated by simulation. Moreover, the metamaterials have been loaded on common waveguide slot antenna according to the surface current distribution. The ultra-broad band radar cross section reduction of the antenna with metamaterials had been theoretically and experimentally investigated by radiating and scattering performances. Experimental and simulated results showed that the proposed antenna with metamaterials performed broadband radar cross section reduction from 3.9 GHz to 18 GHz and the gain had been improved due to the coupling effect between slot and the period structure. The maximal radar cross section reduction achieved 17.81 dB at 8.68 GHz for x-polarized incidence and 21.79 dB at 6.25 GHz for y-polarized waves.

    To determine the accuracy of intraocular lens (IOL) calculations in eyes undergoing phacoemulsification cataract surgery with IOL implantation using immersion A-scan ultrasound (US) and Lenstar LS 900(®) biometry. In this prospective study, 200 eyes of 200 patients were randomized to undergo either Lenstar LS 900(®) or immersion A-scan US biometry to determine the IOL dioptric power prior to phacoemulsification cataract surgery. Post-operative refractive outcomes of these two groups of patients were compared. The result showed no significant difference between the target spherical equivalent (SE) and the post-operative SE value by the Lenstar LS 900(®) (p value = 0.632) or immersion A-scan US biometry (p value = 0.438) devices. The magnitude of difference between the two biometric devices were not significantly different (p value = 0.868). There was no significant difference in the predicted post-operative refractive outcome between immersion A-scan US biometry and Lenstar LS 900(®). Based on the results, the immersion A-scan US technique is as accurate as Lenstar LS 900(®) in the hands of an experienced operator. PMID:25024102

  10. Hydrophobic poly(alkoxysilane) organogels as sorbent material for oil spill cleanup

    International Nuclear Information System (INIS)

    Highlights: • Poly(alkoxysilane) organogels with high absorption capacity were prepared. • The influence of the alkoxysilane length on polymer properties was investigated. • Poly(alkoxysilane) organogels have high and fast oil capacities. • Poly(alkoxysilane) organogels have excellent oil/water selectivity. • Synthesized polymers could be used several times without any capacity loss. - Abstract: In this study, reusable poly(alkoxysilane) organogels with high absorption capacities were synthesized by the condensation of a cyclo aliphatic glycol (UNOXOL™) and altering the chain length of the alkyltriethoxysilanes. The structural and thermal properties of cross-linked poly(alkoxysilane) polymers were determined by FTIR, solid-state 13C and 29Si CPMAS NMR and TGA. The oil absorbency of poly(alkoxysilane)s was determined through oil absorption tests, absorption and desorption kinetics. Results showed that the highest oil absorbency capacities were found to be 295% for hexane, 389% for euro diesel, 428% for crude oil, 652% for gasoline, 792% for benzene, 792% for toluene, 868% for tetrahydrofuran, and 1060% for dichloromethane for the poly(alkoxysilane) gels based on UNOXOL™ and dodecyltriethoxysilane. Owing to their hydrophobic structure, the poly(alkoxysilane) organogels can selectively absorb crude oil from water. The reusability of the absorbents was quantitatively investigated, demonstrating that absorbents can be used effectively at least nine times

    The phase dynamics of Josephson junctions (JJs) under external electromagnetic radiation is studied through numerical simulations. Current-voltage characteristics, Lyapunov exponents, and Poincaré sections are analyzed in detail. It is found that the subharmonic Shapiro steps at certain parameters are separated by structured chaotic windows. By performing a linear regression on the linear part of the data, a fractal dimension of D = 0.868 is obtained, with an uncertainty of ±0.012. The chaotic regions exhibit scaling similarity, and it is shown that the devil's staircase of the system can form a backbone that unifies and explains the highly correlated and structured chaotic behavior. These features suggest a system possessing multiple complete devil's staircases. The onset of chaos for subharmonic steps occurs through the Feigenbaum period doubling scenario. Universality in the sequence of periodic windows is also demonstrated. Finally, the influence of the radiation and JJ parameters on the structured chaos is investigated, and it is concluded that the structured chaos is a stable formation over a wide range of parameter values.

    Full Text Available Osteopontin (OPN is involved in the regulation of vascular calcification processes. The aim of this study was to evaluate the relationship between fasting serum OPN concentration and carotid-femoral pulse wave velocity (cfPWV in geriatric persons. Fasting blood samples were obtained from 93 geriatric persons. cfPWV were performed by SphygmoCor system. Serum OPN levels were measured using a commercially available enzyme-linked immunosorbent assay. Geriatric adults who had diabetes (P=0.007 or dyslipidemia (P=0.029 had higher cfPWV levels than those without diabetes or dyslipidemia. The univariable linear regression analysis showed that age (P=0.002, waist circumference (P=0.048, body mass index (P=0.004, systolic blood pressure (P=0.001, diastolic blood pressure (P=0.036, pulse pressure (P=0.017, creatinine (P=0.002, and log-OPN level (P=0.001 were positively correlated with cfPWV levels, while the high-density lipoprotein cholesterol (HDL-cholesterol level (P=0.007 and glomerular filtration rate (P=0.001 were negatively correlated with cfPWV levels among the geriatric adults. Multivariable forward stepwise linear regression analysis of the significant variables also showed that log-OPN (β=0.233, R2=0.123, regression coefficient: 1.868, P=0.011 was still an independent predictor of cfPWV levels in geriatric persons.

    Several currently used non-polybrominated diphenyl ether (PBDE) brominated flame retardants (BFRs), including hexabromocyclododecanes (HBCDs), 1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE), decabromodiphenyl ethane (DBDPE), hexabromobenzene (HBB), pentabromoethylbenzene (PBEB), and pentabromotoluene (PBT), are examined in the components of a freshwater food web from an electronic waste recycling site, South China. All these BFRs are detectable in the food web, with average concentrations of 13.9-868, 1.71-518, Food web magnification is observed for (+)-alpha-, (-)-alpha-, (+/-)-alpha-, and total HBCDs, and HBB, with trophic magnification factors (TMFs) of 2.22, 2.18, 2.19, 1.82, and 1.46, respectively; whereas there is trophic dilution of BTBPE and PBT through the food web. The TMFs for (+)-alpha-, (-)-alpha-, and (+/-)-alpha-HBCDs are comparable to those of PBDEs detected previously in the same food web. Biota samples show a shift from gamma- toward alpha-HBCD compared with the suspended particles, sediment, and HBCD technical mixtures, with a significant increase of alpha-HBCD on ascending trophic levels. Except for alpha-HBCD in suspended particles and sediment, all the HBCD enantiomers detected are nonracemic in the environmental matrix. In biota, nonracemic residues of alpha-HBCD were observed in mud carp and crucian carp; beta-HBCD in prawn, mud carp, and crucian carp; and gamma-HBCD in water snake, with preferences for (+)-alpha-, (-)-beta-, and (+)-gamma-HBCDs.

    Full Text Available Atmospheric pollution is one of the worst threats to modern society. The consequences derived from different forms of atmospheric pollution vary from the local to the global scale, with deep impacts on climate, environment and human health. Several gaseous pollutants, even when present in trace concentrations, play a fundamental role in important processes that occur in atmosphere. Phenomena such as global warming, photochemical smog formation, acid rain and the depletion of the stratospheric ozone layer are strongly related to the increased concentration of certain gaseous species in the atmosphere. The transport sector significantly produces atmospheric pollution, mainly when diesel oil is used as fuel. Therefore, new methodologies based on selective and sensitive gas detection schemes must be developed in order to detect and monitor pollutant gases from this source. In this work, CO2 Laser Photoacoustic Spectroscopy was used to evaluate ethylene emissions and electrochemical analyzers were used to evaluate the emissions of CO, NOx and SO2 from the exhaust of diesel powered vehicles (rural diesel with 5% of biodiesel, in this paper called only diesel at different engine rotation speeds. Concentrations in the range 6 to 45 ppmV for ethylene, 109 to 1,231 ppmV for carbon monoxide, 75 to 868 ppmV for nitrogen oxides and 3 to 354 ppmV for sulfur dioxide were obtained. The results indicate that the detection techniques used were sufficiently selective and sensitive to detect the gaseous species mentioned above in the ppmV range.

    Twelve representative soil samples were collected from different altitudes on the northern slope of Taibai Mountain to study the distribution and characteristics of soil antagonistic actinomyces by using agar block method. There existed a great deal of soil antagonistic actinomyces in the study area. Among the 141 actinomycete strains isolated, 116 strains (82.3%) showed antagonism toward 12 target bacteria or fungi. The antagonistic strains at altitudes 800-1845, 3488, 3655, and 3670 m occupied 73.7% -86.8%, 81.3%, 78.9% and 82.3% of the total, respectively. 42.1% of the strains at altitudes 1200-2300 m and > 3400 m showed strong and broad spectrum antagonistic activity, suggesting that there was a great potential for the isolation of actinomycete strains with strong anti-biotic capability at these altitudes. 24.1% of the antagonistic actinomycetes showed antagonism against Staphyloccocus aureu, and 2.4%, 6.9% and 11.2% of them showed activity toward Verticillium dahliae in cotton, Phytophthora sp. in strawberry and Neonectria radiciccla in ginseng, respectively. This study showed that the soil actinomycete antagonistic potentiality (SAAP) could be used as a quantitative indicator to evaluate the potential of antagonistic actinomycete resources in soil.

  20. High indoor radon concentrations in an alpine region of western Tyrol

    International Nuclear Information System (INIS)

    In a village in western Tyrol, Austria (Umhausen, 2,600 inhabitants), unusually high indoor radon concentrations were measured, and the lung cancer mortality rate was found to be higher than that of the total population of Tyrol (620,000 inhabitants). Annual means of radon concentrations were found to be particularly high in the area between the two rivers Oetztaler Ache and Hairlachbach, geologically in alluvial fan of a giant rock slide of granitic gneisses (area A, median of annual means on the ground floors: 1,868 Bq m-3); radon concentrations were comparatively low in the rest of the village (area B, median of annual means on the ground floors: 182 Bq m-3). On the basis of these medians, the annual exposures were calculated according to the ICRP model (area A: 58.8 x 105 Bq h m-3; area B: 5.7 x 105 Bq h m-3). Data taken from the Cancer Registry of Tyrol were used to determine the age- and sex-standardized lung cancer mortality rate (area A: 6.17; area B: 1.43). 7 refs., 3 figs., 3 tabs

  1. High efficiency GaAs solar cells using GaInP2 window layers

    International Nuclear Information System (INIS)

    GaAs single-junction solar cells using Ga0.5In0.5P are reported with one sun, air mass (AM) 1.5, global efficiencies of 25.0-25.7%. The open-circuit voltage (Voc), short-circuit current (Jsc), and fill factor (ff) for the 25.7% efficient cell were 1.039 V, 28.5 mA/cm2, and 86.8%, respectively. The devices were grown at 700 degrees C using conventional atmospheric pressure metal organic chemical vapor deposition (MOCVD). The antireflection coating is a double layer of MgF2 and ZnS. Vocs as high as 1.055 V were obtained for some of the devices. This high Voc is attributed to the low interface recombination velocity of the Ga0.5In0.5PGaAs heterointerface. Factors that affect the efficiency of this device, including the thickness and composition of the Ga0.5In0.5P window layer, are presented and discussed

    This study examined, for the first time, whether a high CYP2D6-CYP2C19 metabolic capacity combination increases the likelihood of suicidal intent severity in a large study cohort. Survivors of a suicide attempt (n=587; 86.8% women) were genotyped for CYP2C19 (*2, *17) and CYP2D6 (*3, *4, *4xN, *5, *6, *10, wtxN) genetic variation and evaluated with the Beck Suicide Intent Scale (SIS). Patients with a high CYP2D6-CYP2C19 metabolic capacity showed an increased risk for a severe suicide attempt (P<0.01) as measured by the SIS-objective circumstance subscale (odds ratio (OR)=1.37; 95% confidence interval (CI)=1.05-1.78; P=0.02) after adjusting for confounders (gender, age, level of studies, marital status, mental disorders, tobacco use, family history of suicide, personal history of attempts and violence of the attempt). Importantly, the risk was greater in those without a family history of suicide (OR=1.82; CI=1.19-2.77; P=0.002). Further research is warranted to evaluate whether the observed relationship is mediated by the role of CYP2D6 and CYP2C19 involvement in the endogenous physiology or drug metabolism or both.

    Full Text Available The Eastern Mediterranean region is characterized by one of the highest burdens of paediatric obesity worldwide. This study aims at examining dietary, lifestyle, and socio-economic correlates of overweight, obesity, and abdominal adiposity amongst children and adolescents in Lebanon, a country of the Eastern Mediterranean basin. A nationally representative cross-sectional survey was conducted on 6–19-year-old subjects (n = 868. Socio-demographic, lifestyle, dietary, and anthropometric data (weight, height, waist circumference were collected. Overweight and obesity were defined based on BMI z-scores. Elevated waist circumference (WC and elevated waist to height ratio (WHtR were used as indices of abdominal obesity. Of the study sample, 34.8% were overweight, 13.2% were obese, 14.0% had elevated WC, and 21.3% had elevated WHtR. Multivariate logistic regression analyses showed that male gender, maternal employment, residence in the capital Beirut, sedentarity, and higher consumption of fast food and sugar sweetened beverages were associated with increased risk of obesity, overweight, and abdominal adiposity, while regular breakfast consumption, higher intakes of milk/dairies and added fats/oils were amongst the factors associated with decreased risk. The study’s findings call for culture-specific intervention strategies for the promotion of physical activity, healthy lifestyle, and dietary practices amongst Lebanese children and adolescents.

    Eradication of Helicobacter pylori using first-line therapy is becoming less effective. Subjects who had been treated for H. pylori infection were prospectively enrolled through an on-line database registry from October 2010 to December 2012. Demographic data, detection methods, treatment indication, regimens, durations, compliance, adverse events, and eradication results for H. pylori infection were collected. Data of 3,700 patients from 34 hospitals were analyzed. The overall eradication rate of the first-line therapy was 73.0%. Eradication failure was significantly associated with old age, concomitant medication, and comorbidity. Regional differences in eradication rates were observed. The most common first-line therapy was proton pump inhibitor-based triple therapy (standard triple therapy, STT) for 7 days (86.8%). The eradication rates varied with regimens, being 73% in STT, 81.8% in bismuth-based quadruple therapy, 100% in sequential therapy, and 90.3% in concomitant therapy. The eradication rate in treatment-naïve patients was higher than that in patients previously treated for H. pylori infection (73.8% vs. 58.5%, P eradication rate for second-line therapy was 84.3%. There was no statistical difference in eradication rates among various regimens. H. pylori eradication rate using STT is decreasing in Korea and has become sub-optimal, suggesting the need for alternative regimens to improve the efficacy of first-line therapy for H. pylori infection.

    Xylose is the second most abundant sugar in lignocellulosic materials and can be converted to ethanol by recombinant Saccharomyces cerevisiae yeast strains expressing heterologous genes involved in xylose assimilation pathways. Recent research demonstrated that disruption of the alkaline phosphatase gene, PHO13, enhances ethanol production from xylose by a strain expressing the xylose reductase (XR) and xylitol dehydrogenase (XDH) genes; however, the yield of ethanol is poor. In this study, PHO13 was disrupted in a recombinant strain harboring multiple copies of the xylose isomerase (XI) gene derived from Orpinomyces sp., coupled with overexpression of the endogenous xylulokinase (XK) gene and disruption of GRE3, which encodes aldose reductase. The resulting YΔGP/XK/XI strain consumed 2.08 g/L/h of xylose and produced 0.88 g/L/h of volumetric ethanol, for an 86.8 % theoretical ethanol yield, and only YΔGP/XK/XI demonstrated increase in cell concentration. Transcriptome analysis indicated that expression of genes involved in the pentose phosphate pathway (GND1, SOL3, TAL1, RKI1, and TKL1) and TCA cycle and respiratory chain (NDE1, ACO1, ACO2, SDH2, IDH1, IDH2, ATP7, ATP19, SDH4, SDH3, CMC2, and ATP15) was upregulated in the YΔGP/XK/XI strain. And the expression levels of 125 cell cycle genes were changed by deletion of PHO13. PMID:26769491

    The crystalline quality of aluminum nitride (AlN) epilayers grown on sapphire substrates by MOCVD was improved by increasing hydrogen flow rate during the high temperature growth process. The AlN epilayer exhibited a root mean square (rms) of roughness was 1.944 nm from the 2 x 2 {mu}m{sup 2} size atomic force microscopy (AFM) images. Full widths at half maximum (FWHMs) of (002) and (102) rocking curves of triple-axis high resolution X-ray diffraction (HRXRD) measurements were as narrow as 28.8 arc sec and 868 arc sec, respectively. The optical transmittance spectra showed a sharp absorption edge at a wavelength of 200 nm and strong Fabry-Perot (FP) oscillations. It is proposed that the improvement in crystalline quality is due to the surface in the low-temperature aluminum nitride (LT-AlN) buffer layer is promoted to be stable Al-polarity by the conditions of increasing hydrogen flow rate and ramping up the growth temperature. Addtionally, the parasitic reactions are effectively suppressed by increasing the hydrogen flow rate during the growth process of high temperature. (copyright 2010 WILEY-VCH Verlag GmbH and Co.

    Full Text Available Background. Methicillin-resistant Staphylococcus aureus (MRSA has created significant epidemiological, infection-control, and therapeutic management challenges during the past three decades. Aim. To analyze the pattern of resistance of healthcare- and community-associated MRSA in Egypt and the trend of resistance of HA-MRSA over time (2005–2013. Methods. MRSA isolates were recovered from healthcare-associated (HA and community-associated (CA Staphylococcus aureus (S. aureus infections. They were tested against 11 antimicrobial discs and the minimal inhibitory concentration (MIC of vancomycin was determined. Inducible clindamycin resistance (iMLSB was also screened using D-test. Findings. Of 631 S. aureus, MRSA was identified in 343 (76.6% and 21 (11.5% of HA and CA S. aureus isolates, respectively. The proportion of HA-MRSA increased significantly from 48.6% in 2005 to 86.8% in 2013 (p value < 0.001. Multidrug resistance (MDR was observed in 85.8% of HA-MRSA and 48.6% of CA-MRSA. Vancomycin intermediate resistant S. aureus (VISA was detected in 1.2% of HA-MRSA and none was detected in CA-MRSA. Among HA-MRSA strains, 5.3% showed iMLSB compared to 9.5% among CA-MRSA. Conclusion. The upsurge of the prevalence rates of HA-MRSA over time is alarming and urges for an effective infection control strategy and continuous monitoring of antimicrobial use.

    A heterostructure photovoltaic diode featuring an all-solid-state TiO2/graphene/dye ternary interface with high-efficiency photogenerated charge separation/transport is described here. Light absorption is accomplished by dye molecules deposited on the outside surface of graphene as photoreceptors to produce photoexcited electron-hole pairs. Unlike conventional photovoltaic conversion, in this heterostructure both photoexcited electrons and holes tunnel along the same direction into graphene, but only electrons display efficient ballistic transport toward the TiO2 transport layer, thus leading to effective photon-to-electricity conversion. On the basis of this ipsilateral selective electron tunnelling (ISET) mechanism, a model monolayer photovoltaic device (PVD) possessing a TiO2/graphene/acridine orange ternary interface showed ∼86.8% interfacial separation/collection efficiency, which guaranteed an ultrahigh absorbed photon-to-current efficiency (APCE, ∼80%). Such an ISET-based PVD may become a fundamental device architecture for photovoltaic solar cells, photoelectric detectors, and other novel optoelectronic applications with obvious advantages, such as high efficiency, easy fabrication, scalability, and universal availability of cost-effective materials.

    We report on a LD-end-pumped passively Q-switched Nd:YAG ceramic laser by using a novel single wall carbon nanotube saturable absorber (SWCNT-SA). The SWCNT wafer was fabricated by electric Arc discharge method on quartz substrate with absorption wavelength of 1064 nm. We firstly investigated the continuous wave (CW) laser performance and scattering properties of Nd:YAG ceramic sample. For the case of passively Q-switched operation, a maximum output power of 376 mW was obtained at an incident pump power of 8.68 W at 808 nm, corresponding to an optical-optical conversion efficiency of 4.3%. The repetition rate as the increase of pump power varied from 14 to 95 kHz. The minimum pulse duration of 1.2 μs and maximum pulse energy of 4.5 μJ was generated at a repetition rate of 31.8 kHz.

    Full Text Available In order to screen lignocellulose-degrading superior mushroom strains ten strains of mushrooms (Lentinus edodes939, Pholiota nameko, Lentinus edodes868, Coprinus comatus, Macrolepiota procera, Auricularia auricula, Hericium erinaceus, Grifola frondosa, Pleurotus nebrodensis, and Shiraia bambusicola were inoculated onto carboxymethylcellulose agar-Congo red plates to evaluate their ability to produce carbomethyl cellulase (CMCase. The results showed that the ratio of transparent circle to mycelium circle of Hericium erinaceus was 8.16 (P<0.01 higher than other strains. The filter paper culture screening test showed that Hericium erinaceus and Macrolepiota procera grew well and showed extreme decomposition of the filter paper. When cultivated in guaiacol culture medium to detect their abilities to secrete laccase, Hericium erinaceus showed the highest ability with the largest reddish brown circles of 4.330 cm. CMCase activity determination indicated that Coprinus comatus and Hericium erinaceus had the ability to produce CMCase with 33.92 U/L on the 9th day and 22.58 U/L on the 10th day, respectively, while Coprinus comatus and Pleurotus nebrodensis had the ability to produce laccase with 496.67 U/L and 489.17 U/L on the 16th day and 18th day. Based on the results, Coprinus comatus might be the most promising lignocellulose-degrading strain to produce both CMCase and laccase at high levels.

    Control of small magnetic machines in viscous fluids may enable new medical applications of microrobots. Small-scale viscous environments lead to low Reynolds numbers, and although the flow is linear and steady, the magnetic actuation introduces a dynamic response that is nonlinear. We account for these nonlinearities, and the uncertainties in the dynamic and magnetic properties of the microrobot, by using time-delay estimation. The microrobot consists of a cylindrical magnet, 1 mm long and 500 µm in diameter, and is tracked using a visual feedback system. The microrobot was placed in silicone oil with a dynamic viscosity of 1 Pa.s, and followed step inputs with rise times of 0.45 s, 0.51 s, and 1.77 s, and overshoots of 37.5%, 33.3%, and 34.4% in the x, y, and z directions, respectively. In silicone oil with a viscosity of 3 Pa.s, the rise times were 1.04 s, 0.72 s, and 2.19 s, and the overshoots were 47.8%, 48.5%, and 86.8%. This demonstrates that closed-loop control of the magnetic microrobot was better in the less viscous fluid.

    Cell growth characterization during culturing is an important issue in a variety of biomedical applications. In this study an electrical bioimpedance spectroscopy-based multi-electrode culture monitoring system was developed to characterize cell growth. A PC12 cell line was cultured for the cell growth study. The bioimpedance variations for PC12 cell growth within the initial 12 h were measured over a range between 1 kHz and 4 MHz at three different medium concentrations. Within this frequency range, the largest bioimpedance value was 1.9 times the smallest bioimpedance value. The phase angle decreased over the range from 1 to 10 kHz when cells were growing. Then, the phase angle approached a constant over the frequency range between 10 kHz and 2 MHz. Thereafter, the phase angle increased rapidly from 20 to 52 degrees during cell culturing between 8 and 12 h at 4 MHz. The maximum cell number after culturing for 12 h increased by 25.8% for the control sites with poly-D-lysine (PDL) pastes. For the normal growth factor, the cell number increased up to 4.78 times from 8 to 12 h, but only 0.96 and 1.60 times for the other two medium growth factors. The correlation coefficients between impedance and cell number were 0.868 (coating with PDL), and 0.836 (without PDL) for the normal concentration medium. Thus, impedance may be used as an index for cell growth characterization.

    Objectives Our study aimed to explore the association between the use of effective contraceptive methods and access to different contraceptive services, as well as to describe accessibility-related obstacles when using contraceptive services and satisfaction with those services. Methods From a population-based cross-sectional study carried out in 2004 (response rate 53.8%), the data of 16- to 24-year-old women requiring contraception (N = 868) were analysed. Factors associated with the use of effective contraceptive methods and, specifically, hormonal methods, were explored using multiple logistic regression analysis. Results Effective contraception was used by 75.1% of the respondents. The use of effective contraceptive methods was associated with school-based sexuality education (adjusted prevalence odds ratio 2.69; 95% confidence interval 1.32 - 5.50), visiting a youth-friendly clinic (YFC) (1.82; 1.03-3.23) or a private gynaecologist (2.08; 1.11-3.92). The use of hormonal methods was additionally associated with being a native Estonian speaker and visiting a family doctor. More than half of the respondents reported some obstacle in accessing contraceptive services. The highest satisfaction ratings were given to YFCs. Conclusions Steps to promote the use of services that are youth-friendly and associated with better uptake of effective contraceptive methods are needed among all 16- to 24-year-old women.

    Objective:Myocardial infarction (MI) is the main cause of heart failure, but the relationship between the extent of MI and cardiac function has not been clearly determined.The present study was undertaken to investigate early changes in the electrocardiogram associated with infarct size and cardiac function after MI. Methods: MI was induced by ligating the left anterior descending coronary artery in rats. Electrocardiograms, echocardiographs and hemodynamic parameters were assessed and myocardial infarct size was measured from mid-transverse sections stained with Masson's trichrome. Results:The sum of pathological Q wave amplitudes was strongly correlated with myocardial infarct size (r=0.920, P<0.0001), left ventricular ejection fraction (r=-0.868, P<0.0001) and left ventricular end diastolic pressure (r=0.835, P<0.0004).Furthermore, there was close relationship between MI size and cardiac function as assessed by left ventricular ejection fraction (r=-0.913, P<0.0001) and left ventricular end diastolic pressure (r=0.893, P<0.0001).Conclusion: The sum of pathological Q wave amplitudes after MI can be used to estimate the extent of MI as well as cardiac function.

    Full Text Available Purpose: The present study aims to evaluate, ex vivo, the accuracy of electronic apex locators Root ZX II and Romiapex-15, for working length (WL determination in permanent teeth. Materials and Methods: Fourteen single-rooted teeth (incisors and canines, with their apices fully formed were used. The dental crowns were removed. The anatomic length of the tooth (real measurement was visually determined through the insertion of a size 10 K-file until the tip of the instrument could be observed in the apical foramen under a microscope (20X. Teeth were fixed in a model of resin and adapted into alginate soaked with saline solution, which was used as an  electrical conductor. Using a K-file, root canals were measured electronically using both devices. The results obtained for each apex locator were compared to the real measurements. The accuracy between the devices was statistically analyzed using the Bland-Altman graph, Intraclass Correlation Coefficient (ICC, and Student’s t-test. Results: The mean difference between the measurements using the Root ZX II was 0.277mm greater than the real measurement, while the measurements from the Romiapex-15 were 0.308mm higher on average. The comparison between Root ZX II and Romiapex-15 had no significant difference (p= 0.868. Conclusion: It was concluded that Root ZX II and Romiapex-15 had similar accuracy. Romiapex-15 could be an option for WL determination in permanent teeth.
