    Čerček Vilhar, Emanuela

    2017-01-01

    Holesterol je maščobna molekula, ki v telesu opravlja mnogo funkcij. Njegova biosinteza in pot po telesu kot nepolarna molekula je izredno zapletena. Pri tem se vključuje v lipoproteine in prehaja v jetra, kjer poteka glavna pot presnavljanja ter tvorba žolčnih soli. Značilno je, da holesterol v našem organizmu izvira iz dveh virov. Eno tretjino ga zaužijemo s hrano, preostanek pa ga tvorimo sami iz predhodne molekule acetil-CoA. Ljudje se v današnjem času čedalje pogosteje srečujejo s poviša...

  10. G-Quadruplexes influence pri-microRNA processing.

    Rouleau, Samuel G; Garant, Jean-Michel; Bolduc, François; Bisaillon, Martin; Perreault, Jean-Pierre

    2018-02-01

    RNA G-Quadruplexes (G4) have been shown to possess many biological functions, including the regulation of microRNA (miRNA) biogenesis and function. However, their impact on pri-miRNA processing remains unknown. We identified G4 located near the Drosha cleavage site in three distinct pri-miRNAs: pri-mir200c, pri-mir451a, and pri-mir497. The folding of the potential G4 motifs was determined in solution. Subsequently, mutations disrupting G4 folding led to important changes in the mature miRNAs levels in cells. Moreover, using small antisense oligonucleotides binding to the pri-miRNA, it was possible to modulate, either positively or negatively, the mature miRNA levels. Together, these data demonstrate that G4 motifs could contribute to the regulation of pri-mRNA processing, a novel role for G4. Considering that bio-informatics screening indicates that between 9% and 50% of all pri-miRNAs contain a putative G4, these structures possess interesting potential as future therapeutic targets.

  11. Synthesis and Biological Activity of Diastereomeric and Geometric Analogs of Calcipotriol, PRI-2202 and PRI-2205, Against Human HL-60 Leukemia and MCF-7 Breast Cancer Cells

    Full Text Available Diastereomeric and geometric analogs of calcipotriol, PRI-2202 and PRI-2205, were synthesized as advanced intermediates from vitamin D C-22 benzothiazoyl sulfones and side-chain aldehydes using our convergent strategy. Calcitriol, calcipotriol (PRI-2201 and tacalcitol (PRI-2191 were used as the reference compounds. Among a series of tested analogs the diastereomeric analog PRI-2202 showed the strongest antiproliferative activity on the human breast cancer cell line MCF-7, whereas the geometric analog PRI-2205 was the weakest. Both analogs were less potent in antiproliferative activity against HL-60 cells compared to the reference compounds. The ability to potentiate antiproliferative effect of cisplatin or doxorubicin against HL-60 cells or that of tamoxifen against the MCF-7 cell line was observed at higher doses of PRI-2202 or PRI-2205 than those of the reference compounds. The proapoptotic activity of tamoxifen, expressed as the diminished mitochondrial membrane potential, as well as the increased phosphatidylserine expression, was partially attenuated by calcitriol, PRI-2191, PRI-2201 and PRI-2205. The treatment of the MCF-7 cells with tamoxifen alone resulted in an increase in VDR expression. Moreover, a further increase in VDR expression was observed when the analogs PRI-2201 or PRI-2205, but not PRI-2191, were used in combination with tamoxifen. This observation could partially explain the potentiation of the antiproliferative effect of tamoxifen by vitamin D analogs.

    2012-01-01

    Two bio-indicators, the Photochemical Reflectance Index (PRI) and solar-induced red and far-red Chlorophyll Fluorescence (SIF), were derived from directional hyperspectral observations and studied in a cornfield on two contrasting days in the growing season. Both red and far-red SIF exhibited higher values on the day when the canopy in the early senescent stage, but only the far-red SIF showed sensitivity to viewing geometry. Consequently, the red/far-red SIF ratio varied greatly among azimuth positions while the largest values were obtained for the "hotspot" at both growth stages. This ratio was lower (approx.0.88 +/- 0.4) in early July than in August when the ratio approached equivalence (near approx.1). In concert, the PRI exhibited stronger responses to both zenith and azimuth angles and different values on the two growth stages. The potential of using these indices to monitor photosynthetic activities needs further investigation

  1. Donava in Sava pri Strabonu in v napisih

    Directory of Open Access Journals (Sweden)

    Marjeta Šašel Kos

    2010-12-01

    Full Text Available V članku so zbrana in komentirana tista mesta v Strabonovi 7. knjigi, kjer piše o Donavi in Savi. Že Herodot je Donavo opredelil kot najpomembnejšo njemu znano reko; pri grških piscih se je zanjo uveljavilo tračansko ime Istros, ki se je tudi pozneje uporabljalo za spodnji tok Donave. Zgornji tok se je imenoval Danuvius/Danubius, ime je verjetno keltsko. Kot božanstvu so Danuviju postavljali oltarje; blizu sotočja Drave in Donave so skupaj z njim počastili tudi boga Drava. Savo je poosebljal bog Savus, ki so ga častili ob zgornjem, nevarnejšem toku reke do Siscije. Skupaj z Adsaluto sta imela svetišče nad brzicami pri Podkraju nasproti Hrastnika, blizu območja nevarnih slapov. Strabon poleg drugih rek dvakrat omenja sicer neznani Noar, ki so ga enačili s celo vrsto rek, med drugim tudi z Odro, vendar je natančna analiza Strabonovega besedila pokazala, da gre lahko le za spodnji tok Save. Izviri Save Dolinke v Zelencih pri Podkorenu so bili sveti kraj, kjer so častili Saverkno.

  5. Three causes of variation in the photochemical reflectance index (PRI) in evergreen conifers.

    Science.gov (United States)

    Wong, Christopher Y S; Gamon, John A

    2015-04-01

    The photochemical reflectance index (PRI) reflects diurnal xanthophyll cycle activity and is also influenced by seasonally changing carotenoid : Chl pigment ratios. Both changing pigment pools and xanthophyll cycle activity contribute to photoprotection in evergreen conifers exposed to boreal winters, but they operate over different timescales, and their relative contribution to the PRI signal has often been unclear. To clarify these responses and their contribution to the PRI signal, leaf PRI, pigment composition, temperature and irradiance were monitored over 2 yr for two evergreen conifers (Pinus contorta and Pinus ponderosa) in a boreal climate. PRI was affected by three distinct processes operating over different timescales and exhibiting contrasting spectral responses. Over the 2 yr study period, the greatest change in PRI resulted from seasonally changing carotenoid : Chl pigment ratios, followed by a previously unreported shifting leaf albedo during periods of deep cold. Remarkably, the smallest change was attributable to the xanthophyll cycle. To properly distinguish these three effects, interpretation of PRI must consider temporal context, physiological responses to evolving environmental conditions, and spectral response. Consideration of the separate mechanisms affecting PRI over different timescales could greatly improve efforts to monitor changing photosynthetic activity using optical remote sensing. © 2014 The Authors New Phytologist © 2014 New Phytologist Trust.

  8. Correcting the relationship between PRI and shadow fraction for the blue sky effect

    Science.gov (United States)

    Mõttus, Matti

    2016-04-01

    The Photochemical Reflectance Index (PRI) is defined as the normalized difference ratio of leaf reflectance at two specific wavelengths in the green spectral region. Its value depends on the status of leaf carotenoid content, and especially that of the xanthophyll cycle pigments. Due to the dependence on the xanthophyll cycle, when the photosynthetic apparatus of green leaves is close to the saturation limit, their PRI becomes dependent on light conditions. Therefore, by measuring the PRI of leaves in the same canopy under different local irradiance conditions on a sunny day, it should be possible to determine the saturation level of the leaves. In turn, this gives information on the light use efficiency (LUE) of the vegetation canopy. The average light conditions of visible foliage elements are often quantified with the shadow fraction -- the fraction of visible foliage not lit by direct sunlight. The dependence of PRI on the shadow fraction has been used to remotely measure canopy LUE on clear days. Variations in shadow fraction have been achieved with multiangular measurement. However, besides photosynthetic downregulation, the dependence of canopy PRI on shadow fraction is affected by the blue sky radiation caused by scattering in the atmosphere. To quantify this effect on remotely sensed PRI, we present the underlying definitions relating leaf and canopy PRI and perform the required calculations for typical midsummer conditions in Central Finland. We demonstrate that the effect of blue sky radiation on the variation of PRI with canopy shadow fraction is similar in shape and magnitude to that of LUE variations reported in literature. Next, we propose a new method to assess these PRI variations in structured vegetation. We investiagate this blue sky effect on the PRI -- shadow fraction relationship with high spatial (60 cm) and spectral (9.8 nm) resolution airborne imaging spectroscopy data from Hyytiälä, Finland. We evaluate the spectral irradiance in

    The production, crystal structure, and functional characterization of the C-terminal cysteine-rich secretory protein/antigen 5/pathogenesis related-1 (CAP) domain of pathogen-related yeast protein-1 (Pry1) from Saccharomyces cerevisiae is presented. The CAP domain of Pry1 (Pry1CAP) is functional in vivo as its expression restores cholesterol export to yeast mutants lacking endogenous Pry1 and Pry2. Recombinant Pry1CAP forms dimers in solution, is sufficient for in vitro cholesterol binding, and has comparable binding properties as full-length Pry1. Two crystal structures of Pry1CAP are reported, one with Mg2+ coordinated to the conserved CAP tetrad (His208, Glu215, Glu233 and His250) in spacegroup I41 and the other without divalent cations in spacegroup P6122. The latter structure contains four 1,4-dioxane molecules from the crystallization solution, one of which sits in the cholesterol binding site. Both structures reveal that the divalent cation and cholesterol binding sites are connected upon dimerization, providing a structural basis for the observed Mg2+-dependent sterol binding by Pry1.

    Full Text Available The photochemical reflectance index (PRI is a proxy for light use efficiency (LUE, and is used in remote sensing to measure plant stress and photosynthetic downregulation in plant canopies. It is known to depend on local light conditions within a canopy indicating non-photosynthetic quenching of incident radiation. Additionally, when measured from a distance, canopy PRI depends on shadow fraction—the fraction of shaded foliage in the instantaneous field of view of the sensor—due to observation geometry. Our aim is to quantify the extent to which sunlit fraction alone can describe variations in PRI so that it would be possible to correct for its variation and identify other possible factors affecting the PRI–sunlit fraction relationship. We used a high spatial and spectral resolution Aisa Eagle airborne imaging spectrometer above a boreal Scots pine site in Finland (Hyytiälä forest research station, 61°50′N, 24°17′E, with the sensor looking in nadir and tilted (off-nadir directions. The spectral resolution of the data was 4.6 nm, and the spatial resolution was 0.6 m. We compared the PRI for three different scatter angles ( β = 19 ° , 55 ° and 76 °, defined as the angle between sensor and solar directions at the forest stand level, and observed a small (0.006 but statistically significant (p < 0.01 difference in stand PRI. We found that stand mean PRI was not a direct function of sunlit fraction. However, for each scatter angle separately, we found a clear non-linear relationship between PRI and sunlit fraction. The relationship was systematic and had a similar shape for all of the scatter angles. As the PRI–sunlit fraction curves for the different scatter angles were shifted with respect to each other, no universal curve could be found causing the observed independence of canopy PRI from the average sunlit fraction of each view direction. We found the shifts of the curves to be related to a leaf structural effect on canopy

    Determining the health and vigor of vegetation using high spectral resolution remote sensing is an important goal which has application to monitoring agriculture and ecosystem productivity and carbon exchange. Two spectral indices used to assess whether vegetation is performing near-optimally or exhibiting symptoms of environmental stress (e.g., drought or nutrient deficiency, non-optimal temperatures, etc.) are the Photochemical Reflectance Index (PRI) and solar-induced red and far-red Chlorophyll Fluorescence (Fs). Both the PRI and Fs capture the dynamics of photoprotection mechanisms within green foliage: the PRI is based on the association of the reflected radiation in the green spectrum with the xanthophyll cycle, whereas Fs measures the emitted radiation in the red and far-red spectrum. Fs was determined from retrievals in the atmospheric oxygen absorption features centered at 688 and 760 nm using a modified Fraunhofer Line Depth (FLD) method. We previously demonstrated diurnal and seasonal PRI differences for sunlit vs. shaded foliage in a conifer forest canopy, as expressed in the hotspot and darkspot of the Bidirectional Reflectance Function (BRF). In a USDA-ARS experimental field site located in Beltsville, MD, USA, measurements were acquired over a corn crop from a nadir view in 2008 with an ASD FieldSpec Pro (Analytical Spectral Devices, Inc., Boulder, CO, USA) to study the behavior of the PRI for sunlit and shaded foliage as captured in reflectance variations associated with the BRF, in a I m tall canopy in the vegetative growth stage. Those observations were compared to simulations obtained from two radiative transfer models. Measurements were then acquired to examine whether the PRI and Fs were influenced by view zenith and azimuth geometries at different times of day. Those measurements were made in 2010 with the Ocean Optics USB4000 Miniature Fiber Optic Spectrometer (Ocean Optics Inc., Dunedin, Florida, USA) at several times during the day on

    The Knudsen effusion mass spectrometric technique was used to study vapor species over praseodymium triiodide. The monomer, PrI 3 , and dimer, Pr 2 I 6 , molecules and the negative ions, PrI 4 - and Pr 2 I 7 - , were observed in saturated vapor in the temperature range from 856 K to 1048 K. The partial vapor pressures of neutral constituents were determined and the enthalpies of sublimation obtained using the second and the third laws of thermodynamics (Δ s H deg. (298.15 K) = 291 ± 4 kJ mol -1 for PrI 3 , and Δ s H deg. (298.15 K) = 400 ± 30 kJ mol -1 for Pr 2 I 6 ). The equilibrium constants for various ion molecular reactions were measured and the enthalpies of reactions obtained. The enthalpies of formation, Δ f H deg. (298.15 K) kJ mol -1 , of gaseous molecules and ions were calculated and are as follows: -374 ± 6 (PrI 3 ), -929 ± 30 (Pr 2 I 6 ), -867 ± 30 (PrI 4 - ), -1432 ± 50 (Pr 2 I 7 - )

    Non-photochemical quenching (NPQ) is the most important photoprotective system in higher plants. NPQ can be divided into several steps according to the timescale of relaxation of chlorophyll fluorescence after reaching a steady state (i.e., the fast phase, qE; middle phase, qZ or qT; and slow phase, qI). The dissipation of excess energy as heat during the xanthophyll cycle, a large component of NPQ, is detectable during the fast to middle phase (sec to min). Although thermal dissipation is primarily investigated using indirect methods such as chlorophyll a fluorescence measurements, such analyses require dark adaptation or the application of a saturating pulse during measurement, making it difficult to continuously monitor this process. Here, we designed an unconventional technique for real-time monitoring of changes in thylakoid lumen pH (as reflected by changes in xanthophyll pigment content) based on the photochemical reflectance index (PRI), which we estimated by measuring light-driven leaf reflectance at 531 nm. We analyzed two Arabidopsis thaliana mutants, npq1 (unable to convert violaxanthin to zeaxanthin due to inhibited violaxanthin de-epoxidase [VDE] activity) and npq4 (lacking PsbS protein), to uncover the regulator of the PRI. The PRI was variable in wild-type and npq4 plants, but not in npq1, indicating that the PRI is related to xanthophyll cycle-dependent thermal energy quenching (qZ) rather than the linear electron transport rate or NPQ. In situ lumen pH substitution using a pH-controlled buffer solution caused a shift in PRI. These results suggest that the PRI reflects only xanthophyll cycle conversion and is therefore a useful parameter for monitoring thylakoid lumen pH (reflecting VDE activity) in vivo.

    This study evaluates a direct remote sensing approach from space for the determination of ecosystem photosynthetic light use efficiency (LUE), through measurement of vegetation reflectance changes expressed with the Photochemical Reflectance Index (PRI). The PRI is a normalized difference index based on spectral changes at a physiologically active wavelength (approximately 531 nanometers) as compared to a reference waveband, and is only available from a very few satellites. These include the two Moderate-Resolution Imaging Spectroradiometers (MODIS) on the Aqua and Terra satellites each of which have a narrow (10-nanometer) ocean band centered at 531 nanometers. We examined several PRI variations computed with candidate reference bands, since MODIS lacks the traditional 570-nanometer reference band. The PRI computed using MODIS land band 1 (620-670 nanometers) gave the best performance for daily LUE estimation. Through rigorous statistical analyses over a large image collection (n equals 420), the success of relating in situ daily tower-derived LUE to MODIS observations for northern forests was strongly influenced by satellite viewing geometry. LUE was calculated from CO2 fluxes (moles per moles of carbon absorbed quanta) measured at instrumented Canadian Carbon Program flux towers in four Canadian forests: a mature fir site in British Columbia, mature aspen and black spruce sites in Saskatchewan, and a mixed deciduous/coniferous forest site in Ontario. All aspects of the viewing geometry had significant effects on the MODIS-PRI, including the view zenith angle (VZA), the view azimuth angle, and the displacement of the view azimuth relative to the solar principal plane, in addition to illumination related variables.Nevertheless, we show that forward scatter sector views (VZA, 16 degrees-45 degrees) provided the strongest relationships to daily LUE, especially those collected in the early afternoon by Aqua (r squared = 0.83, RMSE (root mean square error) equals 0

    The N-terminal domain of the PriB protein from the thermophilic bacterium T. tengcongensis (TtePriB) was expressed and its crystal structure has been solved at the atomic resolution of 1.09 Å by direct methods. PriB is one of the components of the bacterial primosome, which catalyzes the reactivation of stalled replication forks at sites of DNA damage. The N-terminal domain of the PriB protein from the thermophilic bacterium Thermoanaerobacter tengcongensis (TtePriB) was expressed and its crystal structure was solved at the atomic resolution of 1.09 Å by direct methods. The protein chain, which encompasses the first 104 residues of the full 220-residue protein, adopts the characteristic oligonucleotide/oligosaccharide-binding (OB) structure consisting of a five-stranded β-barrel filled with hydrophobic residues and equipped with four loops extending from the barrel. In the crystal two protomers dimerize, forming a six-stranded antiparallel β-sheet. The structure of the N-terminal OB domain of T. tengcongensis shows significant differences compared with mesophile PriBs. While in all other known structures of PriB a dimer is formed by two identical OB domains in separate chains, TtePriB contains two consecutive OB domains in one chain. However, sequence comparison of both the N-terminal and the C-terminal domains of TtePriB suggests that they have analogous structures and that the natural protein possesses a structure similar to a dimer of two N-terminal domains.

    Employing remotely sensed techniques to quantify the existence and magnitude of midday photosynthetic downregulation using the photochemical reflectance index (PRI) may reveal new information about plant responses to abiotic stressors in space and time. However, the interpretation and application of the PRI can be confounded because of its sensitivity to several variables changing at the diurnal (e.g., irradiation, shadow fraction) and seasonal (e.g., leaf area, chlorophyll and carotene pigment concentrations, irradiation) time scales. We explored different techniques to correct the PRI for variations in canopy structure and relative chlorophyll content (ChlR) using highly temporally resolved (frequency = five minutes) in-situ radiometric measurements of PRI and the Normalized Difference Vegetation Index (NDVI) over eight soft white spring wheat (Triticum aestivum L.)field plots under varying nitrogen and soil water conditions over two seasons. Our results suggest that the influence of seasonal variation in canopy ChlR and LAI on the diurnally measured PRI (PRIdiurnal) can be minimized using simple correction techniques, therefore improving the strength of PRI as a tool to quantify abiotic stressors such as daily changes in soil volumetric water content (SVWC), and vapor pressure deficit (VPD). PRIdiurnal responded strongly to available nitrogen, and linearly tracked seasonal changes in SVWC, VPD, and stomatal conductance (gc). Utilizing the PRI as an indicator of stress, yield predictions significantly over greenness indices such as the NDVI. This study provides insight towards the future interpretation and scaling of PRI to quantify rapid changes in photosynthesis, and as an indicator of plant stress.

    Full Text Available Balinese sculptors in districts of Ubud and Sukawati, Gianyar, Bali pry into the Law of Pornography. Those who agree state that the law is needed to maintain the morality which has been getting worse, and those who disagree state that it may emasculate their freedom and creativities. This study gives answers to (1 what social practices were performed by the Balinese sculptors to pry into the Law of Pornography?, (2 why did they pry into the application of the law?, and (3 what was the meaning of their prying? Several relevant critical theories such as the theory of structuration, the theory of hegemony, and the theory of aesthetics were eclectically used in this study. The data needed were collected through observation, in-depth interview, documentation study, and library research. The result of the study showed that the Balinese sculptors showed their resistance to the application of the law by making adaptation, changing profession, and still producing pornographic works. The sanction which might be imposed upon them, the consumers of pornographic works decreased, and they were eliminated from exhibitions scared them when they pried into the law. What they did could not be separated from economic, political, ideological, moral, and ethic factors. The meaning of their prying was that it caused them to lose their idealism, their consumers went down, and the number of pornographic works dropped as well.

    The Photochemical Reflectance Index (PRI) is based on the short term reversible xanthophyll pigment changes accompanying plant stress and therefore of the associated photosynthetic activities. Strong relationships between PRI and Light Use Efficiency (LUE) were shown at leaf and canopy scales and over a wide range of species (Garbulsky et al., 2011). But very few previous works have explored the potential link with plant water status. In this study, we have first analyzed the link between PRI and LUE at canopy scale on two different crops in terms of canopy structure and crop management: olive grove (Tunisia) and wheat grown under different water regimes (irrigated or rainfed) and climate zones (France, Morocco). We have investigated the daily and seasonal dynamics of PRI; linking its variations to meteorological factors (global radiation and sun angle effects, soil water content, relative air humidity …) and plant processes. The highest correlations were mainly observed in clear skies conditions. We have found, whatever site, linear negative relationships between PRI and LUE using data acquired in midday (i.e. in solar zenithal angle condition). Linear link between PRI and sapflow measurements was also revealed. This correlation was obtained over periods characterized by a moderate soil water deficit, i.e. by when transpiration rate was mainly control by Vapor Pressure Deficit. We will then briefly presented alternative and complementary approaches to this index, to detect different level of water stress using thermal infrared emissions.

    2006-01-01

    In this paper, we introduce the quantification process for the PRIME-U34i, which is the merged model of ETs (Event Trees) and FTs (Fault Trees) for the level 1 internal PSA of UCN 3 and 4. PRiME-U34i has one top event. Therefore, the quantification process is changed to a simplified method when compared to the past one. In the past, we used the text file called a user file to control the quantification process. However, this user file is so complicated that it is difficult for a non-expert to understand it. Moreover, in the past PSA, ET and FT were separated but in PRiMEU34i, ET and FT were merged together. Thus, the quantification process is different. This paper is composed of five sections. In section 2, we introduce the construction of the one top model. Section 3 shows the quantification process used in the PRiME-U34i. Section 4 describes the post processing. Last section is the conclusions

    Formed by non-covalent interactions and not defined at genetic level, the assemblies of small molecules in biology are complicated and less explored. A common morphology of the supramolecular assemblies of small molecules is nanofibrils, which coincidentally resembles the nanofibrils formed by proteins such as prions. So these supramolecular assemblies are termed as prion-like nanofibrils of small molecules (PriSM). Emerging evidence from several unrelated fields over the past decade implies the significance of PriSM in biology and medicine. This perspective aims to highlight some recent advances of the research on PriSM. This paper starts with description of the intriguing similarities between PriSM and prions, discusses the paradoxical features of PriSM, introduces the methods for elucidating the biological functions of PriSM, illustrates several examples of beneficial aspects of PriSM, and finishes with the promises and current challenges in the research of PriSM. We anticipate that the research of PriSM will contribute to the fundamental understanding at the intersection of supramolecular chemistry and cell biology and ultimately lead to a new paradigm of molecular (or supramolecular) therapeutics for biomedicine.

    NDVI680 [780 nm; 680 nm] using red spectral region, and NDVI570 [780 nm; 570 nm] using the same green spectral region as PRI. All three reflectance indices were significantly related to green LAIe and were able to detect changes in shrubland vegetation among treatments. In general warming treatment...... increased PRI and drought treatment reduced NDVI values. The significant treatment effect on photochemical efficiency of plants detected with PRI could not be detected by fluorescence measurements. However, we found canopy level measured PRI to be very sensitive to soil reflectance properties especially...

    2013-01-01

    In eubacterial organisms, the oriC-independent primosome plays an essential role in replication restart after the dissociation of the replication DNA-protein complex by DNA damage. PriC is a key protein component in the replication restart primosome. Our recent study suggested that PriC is divided into two domains: an N-terminal and a C-terminal domain. In the present study, we determined the solution structure of the N-terminal domain, whose structure and function have remained unknown until now. The revealed structure was composed of three helices and one extended loop. We also observed chemical shift changes in the heteronuclear NMR spectrum and oligomerization in the presence of ssDNA. These abilities may contribute to the PriC-ssDNA complex, which is important for the replication restart primosome. PMID:23868391

    MicroRNA (miRNA)-related single nucleotide polymorphisms (SNPs) may compromise miRNA binding affinity and modify mRNA expression levels of the target genes, thus leading to cancer susceptibility. However, few studies have investigated roles of miRNA-related SNPs in the etiology of cervical carcinoma. In this case–control study of 1,584 cervical cancer cases and 1,394 cancer-free female controls, we investigated associations between two miR-218-related SNPs involved in the LAMB3-miR-218 pathway and the risk of cervical carcinoma in Eastern Chinese women. We found that the pri-miR-218 rs11134527 variant GG genotype was significantly associated with a decreased risk of cervical carcinoma compared with AA/AG genotypes (adjusted OR=0.77, 95% CI=0.63-0.95, P=0.015). However, this association was not observed for the miR-218 binding site SNP (rs2566) on LAMB3. Using the multifactor dimensionality reduction analysis, we observed some evidence of interactions of these two SNPs with other risk factors, especially age at primiparity and menopausal status, in the risk of cervical carcinoma. The pri-miR-218 rs11134527 SNP was significantly associated with the risk of cervical carcinoma in Eastern Chinese women. Larger, independent studies are warranted to validate our findings

    Full Text Available La marque de la séparation des Eglises et de l’Etat semble en France suffisamment forte pour que les points de contact entre service public et prière soient rares et plutôt indirects, à partir de comportements qui n’ont en général pas pour objet d’opposer le seul acte de prière aux normes juridiques et sociales environnantes. Néanmoins à partir des systèmes juridiques et des pratiques d’autres pays d’Europe, les arrêts pragmatiques de la Cour européenne des droits de l'homme révèlent une retenue comparable, même si leur fondement est nécessairement différent.Dans son ensemble, la jurisprudence de la Cour permet de constater que les Etats membres du Conseil de l’Europe ont parfois à l’égard de la prière des attitudes restrictives qui dépendent soit d’une sorte de protection de la religion dominante par rapport aux cultes minoritaires, soit d’un refus implicite de l’athéisme. En revanche, la notion de service public, n’étant pas universellement reconnue en Europe, ne fournit pas un cadre de raisonnement juridique signifiant dans les arrêts, ce qui ne permet d’identifier les rapports entre prières et service public que par le biais du contexte dans lequel se produisent les actes de prière.The mark of the separation between the Church and the State seems sufficiently strong in France so that the points of contact between the civil service and prayer are rare and rather indirect, starting with behaviours which do not have in general aim to oppose the sole act of prayer to the legal and social standards surrounding (First part.

    Full Text Available Abstract Background MicroRNAs (miRNAs regulate gene expression via mRNA cleavage or translation inhibition. In spite of barley being a cereal of great economic importance, very little data is available concerning its miRNA biogenesis. There are 69 barley miRNA and 67 pre-miRNA sequences available in the miRBase (release 19. However, no barley pri-miRNA and MIR gene structures have been shown experimentally. In the present paper, we examine the biogenesis of selected barley miRNAs and the developmental regulation of their pri-miRNA processing to learn more about miRNA maturation in barely. Results To investigate the organization of barley microRNA genes, nine microRNAs - 156g, 159b, 166n, 168a-5p/168a-3p, 171e, 397b-3p, 1120, and 1126 - were selected. Two of the studied miRNAs originate from one MIR168a-5p/168a-3p gene. The presence of all miRNAs was confirmed using a Northern blot approach. The miRNAs are encoded by genes with diverse organizations, representing mostly independent transcription units with or without introns. The intron-containing miRNA transcripts undergo complex splicing events to generate various spliced isoforms. We identified miRNAs that were encoded within introns of the noncoding genes MIR156g and MIR1126. Interestingly, the intron that encodes miR156g is spliced less efficiently than the intron encoding miR1126 from their specific precursors. miR397b-3p was detected in barley as a most probable functional miRNA, in contrast to rice where it has been identified as a complementary partner miRNA*. In the case of miR168a-5p/168a-3p, we found the generation of stable, mature molecules from both pre-miRNA arms, confirming evolutionary conservation of the stability of both species, as shown in rice and maize. We suggest that miR1120, located within the 3′ UTR of a protein-coding gene and described as a functional miRNA in wheat, may represent a siRNA generated from a mariner-like transposable element.

    mirEX is a comprehensive platform for comparative analysis of primary microRNA expression data. RT-qPCR-based gene expression profiles are stored in a universal and expandable database scheme and wrapped by an intuitive user-friendly interface. A new way of accessing gene expression data in mirEX includes a simple mouse operated querying system and dynamic graphs for data mining analyses. In contrast to other publicly available databases, the mirEX interface allows a simultaneous comparison of expression levels between various microRNA genes in diverse organs and developmental stages. Currently, mirEX integrates information about the expression profile of 190 Arabidopsis thaliana pri-miRNAs in seven different developmental stages: seeds, seedlings and various organs of mature plants. Additionally, by providing RNA structural models, publicly available deep sequencing results, experimental procedure details and careful selection of auxiliary data in the form of web links, mirEX can function as a one-stop solution for Arabidopsis microRNA information. A web-based mirEX interface can be accessed at http://bioinfo.amu.edu.pl/mirex.

    Full Text Available To get high efficiency photodegradation on pollutants under visible light, Pr(III doped Y2SiO5 upconversion materials and anatase TiO2 nanofilm coated Pr:Y2SiO5 composite have been prepared by using a sol-gel method. XRD and SEM test results indicated that TiO2 nanofilm was well coated on Pr:Y2SiO5 to form TiO2@Pr:Y2SiO5 composite particles with the sizes of 0.5–1.0 μm. To avoid secondary pollution resulting from incomplete recovery of catalyst particles, TiO2@Pr:Y2SiO5 was loaded on the glass fiber filters by using a dip-coating method. It is found that the catalyst particles were embedded into the carrier firmly, even after having been reused for 6 times. The luminescence intensities of TiO2@Pr:Y2SiO5 were getting down sharply with the coating contents of TiO2 increased, which was attributed to the adsorption of the luminescence by the TiO2 film in situ. As a result, TiO2@Pr:Y2SiO5 with 4% TiO2, which presented lowest luminescence intensity, showed the highest efficiency on the photodegradation of nitrobenzene wastewater. The catalysts loaded on glass fiber filters showed excellent reusability on the photodegradation of nitrobenzene and presented a photodegradation rate of 95% at the first time and up to 75.9% even after 6 times of reusing by the treatment time of 12 h.

    Child-Adult Relationship Enhancement in Primary Care (PriCARE) is a 6-session group parent training designed to teach positive parenting skills. Our objective was to measure PriCARE's impact on child behavior and parenting attitudes. Parents of children 2 to 6 years old with behavior concerns were randomized to PriCARE (n = 80) or control (n = 40). Child behavior and parenting attitudes were measured at baseline (0 weeks), program completion (9 weeks), and 7 weeks after program completion (16 weeks) using the Eyberg Child Behavior Inventory (ECBI) and the Adult Adolescent Parenting Inventory 2 (AAPI2). Linear regression models compared mean ECBI and AAPI2 change scores from 0 to 16 weeks in the PriCARE and control groups, adjusted for baseline scores. Of those randomized to PriCARE, 43% attended 3 or more sessions. Decreases in mean ECBI intensity and problem scores between 0 and 16 weeks were greater in the PriCARE group, reflecting a larger improvement in behavior problems [intensity: -22 (-29, -16) vs -7 (-17, 2), P = .012; problem: -5 (-7, -4) vs -2 (-4, 0), P = .014]. Scores on 3 of the 5 AAPI2 subscales reflected greater improvements in parenting attitudes in the PriCARE group compared to control in the following areas: empathy toward children's needs [0.82 (0.51, 1.14) vs 0.25 (-0.19, 0.70), P = .04], corporal punishment [0.22 (0.00, 0.45) vs -0.30 (-0.61, 0.02), P = .009], and power and independence [0.37 (-0.02, 0.76) vs -0.64 (-1.19, -0.09), P = .003]. PriCARE shows promise in improving parent-reported child-behavior problems in preschool-aged children and increasing positive parenting attitudes. Copyright © 2016 Academic Pediatric Association.

  7. Diurnal and Seasonal Responses of High Frequency Chlorophyll Fluorescence and PRI Measurements to Abiotic Stress in Almonds

    Plants have evolved to efficiently utilize light to synthesize energy-rich carbon compounds, and at the same time, dissipate absorbed but excessive photon that would otherwise transfer excitation energy to potentially toxic reactive oxygen species (ROS). Nevertheless, even the most rapidly growing plants with the highest rates of photosynthesis only utilize about half of the light their leaves absorb during the hours of peak irradiance in sun-exposed habitats. Usually, that daily peak of irradiance coincides with high temperature and a high vapor pressure deficit, which are conditions related to plant stomata closure. Consequently, specially in water stressed environments, plants need to have mechanisms to dissipate most of absorbed photons. Plants avoid photo-oxidative damage of the photosynthetic apparatus due to the formation of ROS under excess light using different mechanisms in order to either lower the amount of ROS formation or detoxify already formed ROS. Photoinhibition is defined as a reduction in photosynthetic activity due largely to a sustained reduction in the photochemical efficiency of Photosystem II (PSII), which can be assessed by monitoring Chlorophyll a fluorescence (ChlF). Alternatively, monitoring abiotic stress effects upon photosynthetic activity and photoinhibition may be possible using high frequency spectral reflectance sensors. We aim to find the potential relationships between high frequency PRI and ChlF as indicators of photoinhibition and permanent photodamage at a seasonal scale. Preliminary results show that PRI responses are sensitive to photoinhibition, but provide a poor representation of permanent photodamage observed at a seasonal scale.

    The authors have previously shown that ad.c. electric arc can be used in the pre-ionizer of a non-equilibrium MHD generator. The pre-ionizer must be located immediately before the duct inlet, where the magnetic field is fairly strong and may have a substantial effect on the current in the gas flow. In the present paper they consider the behaviour of an electric arc in a gas flowing through a magnetic field. The experiments were carried out with argon, using the apparatus described in Ref. [1] of the paper. The flow was set up in a closed glass loop by means of an electromagnetic accelerator (MHD motor). By suitably treating and adjusting the loop it was possible to conduct the investigations in spectrally pure argon. The pressure varied between 1 and 100 mm Hg, and the flow velocity V{sub 0}{<=} 10{sup 4} cm/sec. The magnetic field in the accelerator (B{sub 1}) and near the arc (B{sub 2}) varied between zero and 7 x 10{sup 3} Oe. The spatial distribution of the electron concentration (n{sub e}) and the electron temperature (T{sub e}) were measured using probe and spectrum analysis methods. The gas temperature (T{sub g} ) was measured by the hot wire method and the flow velocity with the help of pitot tubes. Experiments were carried out in both decelerating and accelerating magnetic fields.

    Full Text Available Despite their increasing importance in sedimentology and palaeoecology, non-geniculate coralline algae remain virtually overlooked in Slovenia. Though these plants are present or even abundant in the Cretaceous and Cainozoic strata, they have never been studied in detail with notable exception of corallines from the Lower Oligocene beds in the area of Gornji Grad. Poljšica pri Podnartu is another locality where Lower Oligocene beds are exposed, considered as equivalent to the former. The studied profile consists of pebbly limestone, mudstone, sandstone and limestone. Limestones contain abundant non-geniculate coralline algae. Nine species from six genera of these corallines have been identified: Lithoporella melobesioides (Foslie Foslie, 1909, Neogoniolithon contii (Mastrorilli Quaranta et al., 2007, Spongites sp., Lithothamnion sp. 1, Lithothamnion sp. 2, Mesophyllum sp. 1, Mesophyllum sp. 2, Mesophyllum sp. 3 and Sporolithon sp.

    Full Text Available BACKGROUND: The aim of this study was to investigate the interaction effects of pri-let-7a-1 rs10739971 with pepsinogen C (PGC and excision repair cross complementing group 6 (ERCC6 gene polymorphisms and its association with the risks of gastric cancer and atrophic gastritis. We hoped to identify miRNA polymorphism or a combination of several polymorphisms that could serve as biomarkers for predicting the risk of gastric cancer and its precancerous diseases. METHODS: Sequenom MassARRAY platform method was used to detect polymorphisms of pri-let-7a-1 rs10739971 G → A, PGC rs4711690 C → G, PGC rs6458238 G → A, PGC rs9471643 G → C, and ERCC6 rs1917799 in 471 gastric cancer patients, 645 atrophic gastritis patients and 717 controls. RESULTS: An interaction effect of pri-let-7a-1 rs10739971 polymorphism with ERCC6 rs1917799 polymorphism was observed for the risk of gastric cancer (P interaction = 0.026; and interaction effects of pri-let-7a-1 rs10739971 polymorphism with PGC rs6458238 polymorphism (P interaction = 0.012 and PGC rs9471643 polymorphism (P interaction = 0.039 were observed for the risk of atrophic gastritis. CONCLUSION: The combination of pri-let-7a-1 rs10739971 polymorphism and ERCC6 and PGC polymorphisms could provide a greater prediction potential than a single polymorphism on its own. Large-scale studies and molecular mechanism research are needed to confirm our findings.

    Polycyclic aromatic hydrocarbons (PAHs), organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), heavy metals content and radioactivity levels were measured in 27 soil samples collected from Priština, the capital of Kosovo and Metohija. The sixteen PAHs, twelve OCPs and six PCBs congeners were determined by gas chromatography system with mass spectrometry detection. Although the use of PCBs and OCPs was prohibited decades ago residues of those compounds still existed in measurable concentrations in soils of Priština. PAHs were also present in analyzed samples but their mean concentration was significantly lower than mean concentrations of PAHs previously reported in urban areas in the world. The concentrations of heavy metals (As, Cd, Co, Cr, Cu, Mn, Ni, Pb and Zn) were determined by the EDTA extraction protocols, along with their extractable concentrations. The activity concentrations of natural radionuclides ( 226 Ra, 232 Th and 40 K) were determined by gamma spectrometry method. The Shapiro-Wilk normality test found that activity concentrations of natural radionuclides were normally distributed. Radiological risk was estimated through the annual effective dose, gonadal dose equivalent, excess lifetime cancer risk, radium equivalent activity, external and internal hazard indexes. Spearman correlation coefficient was used for analysis of correlations between physicochemical properties, heavy metal contents and radionuclide activity concentrations. Strong positive correlation between 226 Ra and 232 Th was found, as well as among pairs of As-Cd and Co-Mn. Very strong positive correlation (0.838) at the 0.01 significance level was noted for Pb-Zn pair. Strong correlations indicate common occurrence of these elements in the nature, as well as geogenic association. Copyright © 2016 Elsevier Ltd. All rights reserved.

However, the role of this polymorphism in the prognosis of GC remains largely elusive. Sequenom MassARRAY platform method and the polymerase chain reaction (PCR-restriction fragment length polymorphism were used to investigate pri-let-7a-1 rs10739971 G→A in 334 GC patients. Real-time PCR detected expression of mature let-7a in serum and tissue. Patients with AA or GA+AA genotypes of the pri-let-7a-1 rs10739971 polymorphism demonstrated significantly longer survival time than those with the wild GG genotype. Stratified analysis indicated that survival time was significantly longer in women with AA or GA+AA genotypes and in Borrmann type I/II patients with GA heterozygote or GA+AA genotypes. AA genotype was more frequent in the lymphatic-metastasis-negative subgroup. Serum mature let-7a expression in healthy people with the GA heterozygote and the GA+AA genotype was higher than in those with the GG genotype, and the difference remained significant in the female healthy subgroup. Pri-let-7a-1 rs10739971 polymorphism might be a biomarker for GC prognosis, especially for female and Borrmann type I/II patients. The pri-let-7a-1 rs10739971 polymorphism might affect serum mature let-7a expression, and partly explain the mechanism of the relationship between the pri-let-7a-1 rs10739971 polymorphism and GC survival.

  16. Identification and analysis of genetic variations in pri-miRNAs expressed specifically or at a high level in sheep skeletal muscle.

    Directory of Open Access Journals (Sweden)

    Wei Zhang

    Full Text Available MicroRNAs (miRNAs are key regulators in miRNA-mediated gene regulatory networks and play important roles in many biological processes, such as growth and development of mammals. In this study, we used microarrays to detect 261 miRNAs that are expressed in sheep skeletal muscle. We found 22 miRNAs that showed high levels of expression and equated to 89% of the total miRNA. Genetic variations in these 22 pri-miRNAs were further investigated using polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP and sequencing. A total of 49 genetic variations, which included 41 single nucleotide polymorphisms (SNPs and 8 deletions/insertions, were identified in four sheep breeds. Three variations were further researched in a larger sample set, including five sheep breeds with different meat production performances. We found that the genotype and allele frequencies of the CCC deletion/insertion in pri-miR-133a were significantly related to the sheep meat production trait. Finally, cell assays and quantitative reverse transcription PCR (qRT-PCR were employed to investigate the effect of pri-miRNA genetic variation on the miRNA biogenesis process. The results confirmed that genetic variations can influence miRNA biogenesis and increase or decrease the levels of mature miRNAs, in accordance with the energy and stability change of hair-pin secondary structures. Our findings will help to further the understanding of the functions of genetic variations in sheep pri-miRNAs in skeletal muscle growth and development.

  17. Replication restart in UV-irradiated Escherichia coli involving pols II, III, V, PriA, RecA and RecFOR proteins.

    2002-02-01

    In Escherichia coli, UV-irradiated cells resume DNA synthesis after a transient inhibition by a process called replication restart. To elucidate the role of several key proteins involved in this process, we have analysed the time dependence of replication restart in strains carrying a combination of mutations in lexA, recA, polB (pol II), umuDC (pol V), priA, dnaC, recF, recO or recR. We find that both pol II and the origin-independent primosome-assembling function of PriA are essential for the immediate recovery of DNA synthesis after UV irradiation. In their absence, translesion replication or 'replication readthrough' occurs approximately 50 min after UV and is pol V-dependent. In a wild-type, lexA+ background, mutations in recF, recO or recR block both pathways. Similar results were obtained with a lexA(Def) recF strain. However, lexA(Def) recO or lexA(Def) recR strains, although unable to facilitate PriA-pol II-dependent restart, were able to perform pol V-dependent readthrough. The defects in restart attributed to mutations in recF, recO or recR were suppressed in a recA730 lexA(Def) strain expressing constitutively activated RecA (RecA*). Our data suggest that in a wild-type background, RecF, O and R are important for the induction of the SOS response and the formation of RecA*-dependent recombination intermediates necessary for PriA/Pol II-dependent replication restart. In con-trast, only RecF is required for the activation of RecA that leads to the formation of pol V (UmuD'2C) and facilitates replication readthrough.

    Full Text Available The relationship between culture and nationality and in that sense - national identity of a particular community - is a known thing for a long time. Nationality is usually strongly connected to culture. We will only mention few of their joint characteristics: language, religion, art, customs, tradition etc. In this article special attention will be paid to one of the features of national identity - language - and we will focus on the usage of Cyrillic alphabet of our target group (students of University of Priština, with temporary head office in Kosovska Mitrovica. The study consists of two smaller researches. In the first part we explored reactions of students at University of Priština and we assumed that they will have different reactions towards Cyrillic alphabet and Latin alphabet used as stimuli-words comparing to pupils of Belgrade and Zrenjanin high schools and students of University of Belgrade, Novi Sad and Niš presented in The associative dictionary of Serbian language (Asocjativni rečnik srpskog jezika, 2005. In the second part we tried to find out if our informants prefer the usage of Cyrillic or Latin alphabet, and which one they find better in the esthetic sense. We compared attitudes of students who enroll University of Priština to attitudes of students who enroll University of Belgrade and differences between their attitudes. With both researches we wanted to see if there are formed verbal stereotypes with positive or negative connotation, and what are the attitudes on using Cyrillic alphabet among students in the age of expansion of Latin alphabet. We concluded that Cyrillic alphabet is more used and valued at University of Priština than in the rest of Republic of Serbia and the reason for that might be the stronger sense of national identity among these students.

Because SERRATE is required for pri-miRNA processing, these precursors accumulate in serrate-1 mutants, facilitating their detection using standard RNA-Seq protocols. We first use the mapping of the RNA-Seq reads to the reference genome to annotate the potential primary transcripts of MIRNAs expressed in the embryo. We then quantify these pri-miRNAs in wild type and serrate-1 mutants. Finally, we use differential expression analysis to determine which are up-regulated in serrate-1 compared to wild type, to select the best candidates for bona fide pri-miRNAs expressed in the globular stage embryos. In addition, we analyze a previously published RNA-Seq dataset of wild type and dicer-like 1 mutant embryos at the globular stage [1].

    Full Text Available In a wearable sensor-based deployment, sensors are placed over the patient to monitor their body health parameters. Continuous physiological information monitored by wearable sensors helps doctors have a better diagnostic and a suitable treatment. When doctors want to access the patient’s sensor data remotely via network, the patient will authenticate the identity of the doctor first, and then they will negotiate a key for further communication. Many lightweight schemes have been proposed to enable a mutual authentication and key establishment between the two parties with the help of a gateway node, but most of these schemes cannot enable identity confidentiality. Besides, the shared key is also known by the gateway, which means the patient’s sensor data could be leaked to the gateway. In PriAuth, identities are encrypted to guarantee confidentiality. Additionally, Elliptic Curve Diffie–Hellman (ECDH key exchange protocol has been adopted to ensure the secrecy of the key, avoiding the gateway access to it. Besides, only hash and XOR computations are adopted because of the computability and power constraints of the wearable sensors. The proposed scheme has been validated by BAN logic and AVISPA, and the results show the scheme has been proven as secure.

  3. Characterization of Staphylococcus aureus Primosomal DnaD Protein: Highly Conserved C-Terminal Region Is Crucial for ssDNA and PriA Helicase Binding but Not for DnaA Protein-Binding and Self-Tetramerization.

    Directory of Open Access Journals (Sweden)

    Yen-Hua Huang

    Full Text Available The role of DnaD in the recruitment of replicative helicase has been identified. However, knowledge of the DNA, PriA, and DnaA binding mechanism of this protein for the DnaA- and PriA-directed replication primosome assemblies is limited. We characterized the DNA-binding properties of DnaD from Staphylococcus aureus (SaDnaD and analyzed its interactions with SaPriA and SaDnaA. The gel filtration chromatography analysis of purified SaDnaD and its deletion mutant proteins (SaDnaD1-195, SaDnaD1-200 and SaDnaD1-204 showed a stable tetramer in solution. This finding indicates that the C-terminal region aa 196-228 is not crucial for SaDnaD oligomerization. SaDnaD forms distinct complexes with ssDNA of different lengths. In fluorescence titrations, SaDnaD bound to ssDNA with a binding-site size of approximately 32 nt. A stable complex of SaDnaD1-195, SaDnaD1-200, and SaDnaD1-204 with ssDNA dT40 was undetectable, indicating that the C-terminal region of SaDnaD (particularly aa 205-228 is crucial for ssDNA binding. The SPR results revealed that SaDnaD1-195 can interact with SaDnaA but not with SaPriA, which may indicate that DnaD has different binding sites for PriA and DnaA. Both SaDnaD and SaDnaDY176A mutant proteins, but not SaDnaD1-195, can significantly stimulate the ATPase activity of SaPriA. Hence, the stimulation effect mainly resulted from direct contact within the protein-protein interaction, not via the DNA-protein interaction. Kinetic studies revealed that the SaDnaD-SaPriA interaction increases the Vmax of the SaPriA ATPase fivefold without significantly affecting the Km. These results indicate that the conserved C-terminal region is crucial for ssDNA and PriA helicase binding, but not for DnaA protein-binding and self-tetramerization.

    Full Text Available Les points de rencontre entre prière et droit sont nombreux, y compris en France où, du fait de la Séparation, on serait fondé à considérer de telles rencontres comme illégitimes sinon impossibles, la prière se référant au religieux donc à la sphère privée et le droit à la justice donc à la sphère publique. Cet essai se propose de démontrer que dans la réalité, les cloisons entre le privé et le public sont moins étanches et les relations entre la religion et le droit plus étroites qu’il n’y paraît. Après avoir évoqué les systèmes de droit religieux (droit canon, charia, halakha produits en marge des droits nationaux, rappelé la diversité des liens juridiques entre État et religion (théocratie, monarchie de droit divin, religion d’État – avec ou sans reconnaissance de minorités religieuses tolérées –, religion de la majorité, pluralisme, Concordat, laïcité, séparation, athéisme d’État et la pluralité des niveaux et sources de normativité au sein même des systèmes religieux, l’article se concentre sur la prière et en décline les différents aspects. En effet, la prière n’est pas plus monolithique que le droit. Exercice solitaire ou pratique collective, expression spontanée ou normée de la foi, du sentiment religieux ou de l’appartenance confessionnelle, affirmation identitaire ou communautaire, la prière est diverse dans ses formes et ses contenus comme dans ses usages. Acte social ou militant, dès lors qu’elle se risque à franchir le seuil de la sphère privée du religieux, la prière rencontre la loi.Meeting points between prayers and the law are many, including in France where, because of the separation between the Church and the State, one would be entitled to consider such junctures as illegitimate if not impossible since prayer is linked to the religious and therefore the private sphere whereas law concerns justice and therefore the public sphere.

  5. Monitoring phenology of photosynthesis in temperate evergreen and mixed deciduous forests using the normalized difference vegetation index (NDVI) and the photochemical reflectance index (PRI) at leaf and canopy scales

    Evergreen conifers in boreal and temperate regions undergo strong seasonal changes in photoperiod and temperatures, which determines their phenology of high photosynthetic activity in the growing season and downregulation during the winter. Monitoring the timing of the transition between summer activity and winter downregulation in evergreens is difficult since this is a largely invisible process, unlike in deciduous trees that have a visible budding and a sequence of leaf unfolding in the spring and leaf abscission in the fall. The light-use efficiency (LUE) model estimates gross primary productivity (GPP) and may be parameterized using remotely sensed vegetation indices. Using spectral reflectance data, we derived the normalized difference vegetation index (NDVI), a measure of leaf "greenness", and the photochemical reflectance index (PRI), a proxy for chlorophyll:carotenoid ratios which is related to photosynthetic activity. To better understand the relationship between these vegetation indices and photosynthetic activity and to contrast this relationship between plant functional types, the phenology of NDVI, PRI and photosynthesis was monitored in an evergreen forest and a mixed deciduous forest at the leaf and canopy scale. Our data indicates that the LUE model can be parameterized by NDVI and PRI to track forest phenology. Differences in the sensitivity of PRI and NDVI will be discussed. These findings have implications to address the phenology of evergreen conifers by using PRI to complement NDVI in the LUE model, potentially improving model productivity estimates in northern hemisphere forests, that are dominated by conifers.

    Full Text Available Abstract Background microRNAs (miRNAs are endogenous small non-coding RNAs that post-transcriptionally regulate gene expression. In plants, they typically show high complementarity to a single sequence motif within their target mRNAs and act by catalyzing specific mRNA cleavage and degradation. miRNAs are processed from much longer primary transcripts via precursor miRNAs containing fold-back structures. Leaving these secondary structures intact, miRNAs can be re-designed experimentally to target mRNAs of choice. Results We designed primary synthetic miRNAs (pri-smiRNAs on the basis of the primary transcript of the Arabidopsis MIR159A gene by replacing the original miR159a and the corresponding miR159a* with novel sequences, keeping the overall secondary structure as predicted by the program RNAfold. We used the program RNAhybrid to optimize smiRNA design and to screen the complete Arabidopsis transcriptome for potential off-targets. To improve the molecular cloning of the pri-smiRNA we inserted restriction sites in the original MIR159A primary transcript to easily accommodate the smiRNA/smiRNA* DNA fragment. As a proof-of-concept, we targeted the single gene encoding chalcone synthase (CHS in Arabidopsis. We demonstrate smiRNA(CHS expression and CHS mRNA cleavage in different transgenic lines. Phenotypic changes in these lines were observed for seed color and flavonol derivatives, and quantified with respect to anthocyanin content. We also tested the effect of mismatches and excess G:U base pairs on knockdown efficiency. Conclusions RNAhybrid-assisted design of smiRNAs and generation of pri-smiRNAs using a novel vector containing restriction sites greatly improves specificity and speed of the generation of stable knockdown lines for functional analyses in plants.

    Full Text Available Les premiers combats de la classe ouvrière se sont portés sur la demande d’une journée de repos, qui par tradition chrétienne a été fixée le dimanche en 1906. Quatre journées de congé à caractère chrétien ont en outre été retenues par le législateur. L’exercice du culte est donc concrètement garanti pour les chrétiens. Avec l’arrivée sur le territoire de la République  de populations de confessions variées, cette organisation du travail apparaît inégalitaire, voire de nature à porter atteinte à la liberté religieuse. Il a été proposé de reconnaître les jours de prières d’autres confessions. Pour l’instant, le législateur n’a pas adopté ces propositions. Mais la question reste posée. Or, la jurisprudence des tribunaux judiciaires et administratifs admet le droit de prier des fidèles des cultes minoritaires, ils peuvent prétendre à un congé lors des fêtes de leur religion dans la mesure où cela n’occasionne pas de perturbation. La consécration de cette jurisprudence souple par le législateur serait de nature à calmer le débat.At the turn of the century, the working classes fought for a day off in the week, which was granted on Sundays by the legislator in 1906. Four additional christian holidays are also legal. So the right to pray is garanteed for christians. As different populations with various faiths settled in France, this organisation has seemed to violate the principle of equality, and religious freedom. There has been a debate on the question whether some of the days of minority religions should also be observed by all the population. But so far, the legislator has not voted any of these proposals. It remains an issue. The French judge has consistently decided that the people of non christian faiths had the right to be granted a day off to pray on these special days, provided it would not cause prejudice to the organisation they work for. It might help to calm the debate if this

  12. Zeaxanthin-independent energy quenching and alternative electron sinks cause a decoupling of the relationship between the photochemical reflectance index (PRI) and photosynthesis in an evergreen conifer during spring.

    In evergreen conifers, the winter down-regulation of photosynthesis and its recovery during spring are the result of a reorganization of the chloroplast and adjustments of energy-quenching mechanisms. These phenological changes may remain undetected by remote sensing, as conifers retain green foliage during periods of photosynthetic down-regulation. The aim was to assess if the timing of the spring recovery of photosynthesis and energy-quenching characteristics are accurately monitored by the photochemical reflectance index (PRI) in the evergreen conifer Pinus strobus. The recovery of photosynthesis was studied using chlorophyll fluorescence, leaf gas exchange, leaf spectral reflectance, and photosynthetic pigment measurements. To assess if climate change might affect the recovery of photosynthesis, seedlings were exposed to cold spring conditions or warm spring conditions with elevated temperature. An early spring decoupling of the relationship between photosynthesis and PRI in both treatments was observed. This was caused by differences between the timing of the recovery of photosynthesis and the timing of carotenoid and chlorophyll pool size adjustments which are the main factors controlling PRI during spring. It was also demonstrated that zeaxanthin-independent NPQ mechanisms undetected by PRI further contributed to the early spring decoupling of the PRI-LUE relationship. An important mechanism undetected by PRI seems to involve increased electron transport around photosystem I, which was a significant energy sink during the entire spring transition, particularly in needles exposed to a combination of high light and cold temperatures. © The Author 2015.

    Full Text Available Throughout most of the twentieth century; Mexico’s political and economic policies were heavily influenced by the Partido Revolucionario Institutional (PRI. The landmark 1998 victory by Vicente Fox, the first presidential candidate in seven decades to win without the official sanction of the PRI,marked an important milestone in Mexican history; Octavio Paz, an eloquent proponent of political, economic, and social reform, sought for decades to inspire change. This paper seeks to illuminate Paz’s economic philosophy, and to demonstrate how the acclaimed writer, through courageous symbolic action coupled with an inimitable and potent pen, challenged the PRI’s hegemony in Mexico and contributed to the historic election he almost lived to celebrate (an elderly Paz died shortly before the historic 1998 election.“The Aztec ritual of 2 October [1968] in the Plaza de Tlatelolco. . . convinced me to abandon the Mexican Foreign Service.”“October 2, 1968 ended the student movement.

    This study investigates the performances of different optical indices to estimate gross primary production (GPP) of herbaceous stratum in a Mediterranean savanna with different Nitrogen (N) and Phosphorous (P) availability. Sun-induced chlorophyll Fluorescence yield computed at 760 nm (Fy760), scaled-photochemical reflectance index (sPRI), MERIS terrestrial-chlorophyll index (MTCI) and Normalized difference vegetation index (NDVI) were computed from near-surface field spectroscopy measurements collected using high spectral resolution spectrometers covering the visible near-infrared regions. GPP was measured using canopy-chambers on the same locations sampled by the spectrometers. We hypothesized that light-use efficiency (LUE) models driven by remote sensing quantities (RSM) can better track changes in GPP caused by nutrient supplies compared to those driven exclusively by meteorological data (MM). Particularly, we compared the performances of different RSM formulations - relying on the use of Fy760 or sPRI as proxy for LUE and NDVI or MTCI as fraction of absorbed photosynthetically active radiation (fAPAR) - with those of classical MM. Results showed significantly higher GPP in the N fertilized experimental plots during the growing period. These differences in GPP disappeared in the drying period when senescence effects masked out potential differences due to plant N content. Consequently, although MTCI was tightly related to plant N content (r2 = 0.86, p < 0.01), it was poorly related to GPP (r2 = 0.45, p < 0.05). On the contrary sPRI and Fy760 correlated well with GPP during the whole measurement period. Results revealed that the relationship between GPP and Fy760 is not unique across treatments but it is affected by N availability. Results from a cross validation analysis showed that MM (AICcv = 127, MEcv = 0.879) outperformed RSM (AICcv = 140, MEcv = 0.8737) when soil moisture was used to constrain the seasonal dynamic of LUE.

    Full Text Available Amatoxins and phallotoxins are toxic cyclopeptides found in the genus Amanita and are among the predominant causes of fatal food poisoning in China. In the treatment of Amanita mushroom poisoning, an early and definite diagnosis is necessary for a successful outcome, which has prompted the development of protocols for the fast and confirmatory determination of amatoxins and phallotoxins in human biological fluids. For this purpose, a simple, rapid and sensitive multiresidue UPLC-MS/MS method for the simultaneous determination of α-amanitin, β-amanitin, γ-amanitin, phalloidin (PHD and phallacidin (PCD in human plasma, serum and urine was developed and validated. The diluted plasma, serum and urine samples were directly purified with a novel PRiME technique on a 96-well μElution plate platform, which allowed high-throughput sample processing and low reagent consumption. After purification, a UPLC-MS/MS analysis was performed using positive electrospray ionization (ESI+ in multiple reaction monitoring (MRM mode. This method fulfilled the requirements of a validation test, with good results for the limit of detection (LOD, lower limit of quantification (LLOQ, accuracy, intra- and inter-assay precision, recovery and matrix effects. All of the analytes were confirmed and quantified in authentic plasma, serum and urine samples obtained from cases of poisoning using this method. Using the PRiME μElution technique for quantification reduces labor and time costs and represents a suitable method for routine toxicological and clinical emergency analysis.

    Full Text Available The years 1985 and 1986 saw a rescue excavation by archaeologists from the Institute for the Protection of Cultural Heritage of Slovenia, Celje Regional Office, performed on the severely damaged Iron Age tumulus in the village of Črnolica pri Šentjurju. The village lies in the close vicinity of the Rifnik hill, the site of one of the largest known hilltop settlements in Slovenia dating from the Late Bronze and Iron Ages. The excavation in Črnolica yielded a stone grave chamber of monumental dimensions, together with fragmented and decontextualised grave goods. These included a large set of quality ceramic vessels, a considerable number of bronze vessels, glass cups, fibulae, and a horse harness. Of special importance are three bronze items fabricated in Etruria, which carry the protomas of an aquatic bird, horses, and a ram. The burial dates to the Hallstatt C2 period or the second half of the 7th century BC. Aquatic birds are positioned on all four vertexes of the presentatoio, a special type of vessel presumably used for libation rituals. Comparable items have come to light in the richest graves of the Iron Age aristocracy of Etruria, Latium Vetus and Bologna, and date to the end of the 8th and the beginning of the 7th centuries BC. The aquatic bird sculptures on the presentatoio are stylised, displaying features of the Late Italic Geometric style. This motif marks various Late Bronze and Iron Age items associated with ritual activities in the greater part of Europe, connecting them with prehistoric religious beliefs. While the assumption that they refer to the sun divinisation cult is not proven, they must have signified some prehistoric aspect of the holy or numinous. The two anthropomorphic legs with an attached horse protoma found in the Črnolica tumulus were reconstructed as a part of a tripod of small dimensions, which can be classified as a member of the so-called horse tripod family, fine products of the Italic Geometric style

    Attention deficit and hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder characterized by impairment to sustain attention and inability to control impulses and activity level. The etiology of ADHD is complex, with an estimated heritability of 70-80%. Under the hypothesis that alterations in the processing or target binding of microRNAs (miRNAs) may result in functional alterations predisposing to ADHD, we explored whether common polymorphisms potentially affecting miRNA-mediated regulation are involved in this psychiatric disorder. We performed a comprehensive association study focused on 134 miRNAs in 754 ADHD subjects and 766 controls and found association between the miR-34b/c locus and ADHD. Subsequently, we provided preliminary evidence for overexpression of the miR-34c-3p mature form in peripheral blood mononuclear cells of ADHD subjects. Next, we tested the effect on gene expression of single-nucleotide polymorphisms within the ADHD-associated region and found that rs4938923 in the promoter of the pri-miR-34b/c tags cis expression quantitative trait loci for both miR-34b and miR-34c and has an impact on the expression levels of 681 transcripts in trans, including genes previously associated with ADHD. This gene set was enriched for miR-34b/c binding sites, functional categories related to the central nervous system, such as axon guidance or neuron differentiation, and serotonin biosynthesis and signaling canonical pathways. Our results provide preliminary evidence for the contribution to ADHD of a functional variant in the pri-miR-34b/c promoter, possibly through dysregulation of the expression of mature forms of miR-34b and miR-34c and some target genes. These data highlight the importance of abnormal miRNA function as a potential epigenetic mechanism contributing to ADHD.

En organos de grandes dimensiones, como el higado, se evita la superposicion de las radiaciones procedentes de la parte posterior del organo, lo que permite detectar mejor las lesiones superficiales. El. emisor,gamma de baja energia mas importante es el {sup 125}I. Para la exploracion de la tiroides se utiliza en forma de yoduro. El Rosa Bengala marcada con {sup 125}I es un compuesto adecuado para la exploracion del higado. Tambien puede utilizarse albumina desnaturalizada por el calor, marcada con {sup 125}I. Para la exploracion del rinon se ha comprobado que el hipuran marcado con {sup 125}I da buenos resultados cuando se inyecta por via intramuscular con hialuronidasa a fin de lograr un nivel uniforme de radiactividad en este organo. Otro emisor gamma de baja energia muy util para la exploracion medica es el {sup 197}Hg que puede utilizarse en forma de cloruro para la exploracion de los rinones y el bazo. Deben tomarse precauciones especiales para evitar la superposicion del rinon y el bazo. La exploracion da mejores resultados si se utiliza {sup 197}Hg marcado con neohidrina. Este compuesto puede emplearse tambien para la localizacion de tumores del cerebro.

    Full Text Available Las encefalopatías espongiformes transmisibles (EETs son enfermedades neurodegenerativas fatales que afectan a humanos y ciertas especies animales. La hipótesis más aceptada indica que el agente infeccioso, denotado como prion y compuesto principalmente por la Proteína Priónica Scrapie (PrPSc, corresponde a una conformación anormal de una proteína codificada por el huésped denominada Proteína Priónica Celular (PrPC, cuya función es aún desconocida; sin embargo, la expresión ubicua de PrPC así como su elevado grado de conservación entre especies, sugieren un papel importante para esta proteína. En este trabajo se detectó a la PrPC en diferentes tipos celulares incluyendo un cultivo primario de células de peces (Tilapia, Oreochromis spp.. Además, basándonos en la secuencia de la PrPC humana, se diseñó un RNA de interferencia (siRNA con el fin de silenciar el gen PRNP en células neuronales SK-SY5Y. El siRNA diseñado inhibió la expresión de PrPC a lo largo de las 96 h post-transfección y las células silenciadas fueron menos susceptibles a la infección por HSV-1 y HSV-2, en comparación con células no transfectadas con el siRNA.

Los resultados muestran que el plasma sufre difusion del campo magnetico en las fases iniciales y enfriamiento de los electrones por irradiacion debida a impurezas o por conduccion termica a lo largo de las lineas de fuerza. Como consecuencia, el valor {beta} del plasma desciende a 0,5 aproximadamente, a la densidad magnetica maxima, con lo que se agrandan las aberturas magneticas de los extremos de la bobina, originando asi el escape axial del plasma. Los principales problemas aun pendientes de solucion se refieren al perfeccionamiento de un dispositivo de precalentamiento que permita obtener un plasma de temperatura mas elevada con un valor {beta} proximo a la unidad, y a la reduccion de la velocidad de perdida de energia delos electrones.

    In Parkinson's disease, intracellular α-synuclein inclusions form in neurons. We suggest that prion-like behavior of α-synuclein is a key component in Parkinson's disease pathogenesis. Although multiple molecular changes are involved in the triggering of the disease process, we propose that neuron-to-neuron transfer is a crucial event that is essential for Lewy pathology to spread from one brain region to another. In this review, we describe key findings in human postmortem brains, cultured cells, and animal models of disease that support the idea that α-synuclein can act as a prion. We consider potential triggers of the α-synuclein misfolding and why the aggregates escape cellular degradation under disease conditions. We also discuss whether different strains of α-synuclein fibrils can underlie differences in cellular and regional distribution of aggregates in different synucleinopathies. Our conclusion is that α-synuclein probably acts as a prion in human diseases, and a deeper understanding of this step in the pathogenesis of Parkinson's disease can facilitate the development of disease-modifying therapies in the future.

Encontraron que el desplazamiento mediante HCl del HSO{sub 3}{sup -} fijado en los intercambiadores anionicos constituye un metodo excelente para lograr condiciones de contracorriente y de reflujo total en este sistema. Destacan algunos inconvenientes del metodo, que derivan de la necesidad de trabajar con un reflujo muy intenso. En el instituto de tecnologia de Estocolmo se ha construido una instalacion en que se aplica este proceso, y la memoria indica los parametros obtenidos y la experiencia adquirida durante su funcionamiento, asi como los resultados experimentales. El enriquecimiento obtenido, muy inferior al calculado segun los resultados de laboratorio, se atribuye a la formacion de una ''cola'' de H{sub 2}SO{sub 3} en la fase HCl. Los autores han investigado este problema y encuentran que quiza se pudiera resolver empleando disolventes organicos en vez de soluciones acuosas.

    -etileno se discuten en funcion de dos mecanismos de insercion previamente propuestos, a saber, la insercion del atomo de carbono en los enlaces C = C y C-H para formar compuestos de adicion C-C{sub 2}H{sub 4}. Al aumentar la concentracion de neon no desaparece ningun producto, pero los rendimientos relativos sufren modificaciones considerables. Los productos tales como el acetileno y el vinil-acetileno que pueden formarse a partir de los compuestos iniciales de adicion C-C{sub 2}H{sub 4}, en virtud de procesos que requieren gran cantidad de energia, disminuyen en importancia, mientras que aumenta el rendimiento de los productos formados por procesos que exigen poca energia, tales como los compuestos C{sub 5}. Algo semejante sucede con el etano. Los estudios por degradacion han mostrado que la distribucion intramolecular de {sup 11}C en el aleno y el metilacetileno formados a partir de etileno es afectada por el efecto moderador del neon. Ello implica la participacion de los enlaces C = C y C-H en la formacion de estos productos, asi como una relacion de dependencia entre la razon de ataque en esos dos tipos de enlace y la energia cinetica del atomo de carbono que interviene en la reaccion. Otros estudios con indicadores dobles acerca de la formacion de acetileno a partir de moleculas sencillas tales como CH{sub 2}CD{sub 2}, CH{sub 3}CH{sub 2}D, CD{sub 3}CDH{sub 2} y a partir de varias mezclas de otros alcanos y alquenos marcados indican que la perdida de energia cinetica por el atomo de carbono ejerce escaso efecto en el indice relativo de ataque en varios tipos de enlace C-H.

Con camaras de recuento Ne/Ar midieron los aportes de rayos {gamma}. Estas determinaciones demostraron que la contribucion de los rayos {gamma} es inferior al 0,8% mientras que la contribucion de los neutrones termicos y epitermicos en conjunto es inferior al 0,01% de la dosis total, expresada en rad. Los sujetos se expusieron a dosis medias en el eje central que variaban entre 180 y 1200 rad, en correspondencia con energias neutronicas comprendidas entre 396 y 658 keV {+-} 50 keV, a fin de abarcar la region de las resonancias del N y del O. Se comprobo que la letalidad varia pronunciadamente con la energia neutronica, siendo igualmente funcion pronunciada, pero independiente de la distribucion de la dosis. Sin embargo, sea cual fuere la dosis, la energia o la distribucion todos los animales que sobrevivieron S dias llegaron a sobrevivir por lo menos 144 dias muriendo luego a consecuencia de los habituales efectos diferidos.

(author) [Spanish] En el marco de un vasto estudio sobre la distribucion en el oceano Atlantico de los raclionuclidos de periodo largo procedentes de precipitaciones radiactivas, se han efectuado numerosas mediciones de la concentracion del cerio-144 y del promecio-147. Una comporacion de las variaciones horizontales y verticales de estas concentraciones con las concentraciones del estroncio-90, que fueron medidas al mismo tiempo, demuestra que las tierras rasas suelen abundar menos en las aguas superficiales que los nuclidos que se sabe son solubles. Esta observacion, unida al hecho de que se ha observado a menudo un enriquecimiento de las aguas profundas en tierras raras, permite afirmar que esos elementos experimentan un rapido transporte vertical al fijarse a particulas en vias de sedimentacion. Esta hipotesis es perfectamente compatible con el comportamiento ''radiocoloidal'' caracteristico de las tierras raras al pH del agua de mar. En la memoria se procura interpretar este estudio en el contexto de las propiedades generales de los cationes trivalentes en geoquimica marina; asimismo, se ponen de manifiesto los aspectos caracteristicos y la utilidad general de este ensayo de utilizacion de las precipitaciones como indicadores radiactivos.

    resultado de la superposicion de toda una serie de procesos : formacion de atomos de cloro radiactivo, separacion radiolitica del haluro, difusion de los productos obtenidos en la red cristalina del carbono, su sorcion en la superficie y su recombinacion en distintos centros. La extraordinaria variedad de condiciones en que se forman e interaccionan los productos de irradiacion con el esqueleto carbonico y su superficie depende de un gran numero de factores, a saber : la estructura ultramicroscopica, la naturaleza de los nuevos compuestos, que estan relacionados con el tipo de compuestos superficiales, la existencia en la superficie del carbono de centros con un espectro continuo de energia de sorcion, la probable formacion de diversos centros estacionarios de recombinacion por irradiacion del carbono, etc. Por ello, las tecnicas utilizadas ofrecen la posibilidad de realizar una gran variedad de experimentos a fin de establecer las condiciones optimas de enriquecimiento.

Los accidentes cerebro-vasculares han originado en la tercera parte de los casos anomalias en los graficos; la mitad de los graficos anormales presenta el aspecto caracteristico de los reblandecimientos (o trombosis), lo cual permite su diagnoestico; el resta de los graficos es semejante a los graficos tumorales, siendo la unica diferencia que, en caso de accidente vascular, las anomallas desaparecen despues de algunas semanas; las dos terceras partes de estas lesiones dan un gammaencefalogram a negativo. Los aneurismas arteriales, los centros epileptoegenos no tumorales y las distintas afecciones puramente neurologicas presentan resultados normales en el 96 por ciento de los casos. La exploration del cerebro mediante albumina radiactiva puede suministrar informaciones de gran valor, no solo respecta de la existencia de una lesion neuro-quirurgica y su localizacion exacta, sino tambien respecto de su naturaleza. En particular, facilita grandemente el diagnostico de un meningeoma, de un glioblastoma o de metastasis. Esta, ademas de las informaciones relativas al diagnoestico positivo y topografico, hace que este procedimiento sea uno de los metodos mas interesantes de diagnostico neurologico.

    Full Text Available Prilikom upotrebe minsko-eksplozivnih sredstava za rušenje elemenata, materijala i objekata jako je bitna organizacija izvođenja radova prilikom pripreme i u toku izvođenja samog rušenja. Za izvođenje ovih radova u Vojsci Srbije postoje specijalizovane i namenske jedinice. Radi se o jedinicama jedne od specijalnosti u okviru roda inžinjerije, pionirske specijalnosti, koje egzistiraju u okviru inžinjerijskih bataljona, odnosno brigada KoV. Organizacija inžinjerijskih radova zapravo predstavlja iznalaženje najcelishodnijeg rešenja u pogledu upotrebe pokretnih stvari, ali i naprezanja ljudstva, pri rušenju konkretnog objekta – deonice puta. Pri tome veliki problem predstavlja literatura, a posebno norme za izvođenje radova, jer izuzev nekoliko skripti za internu upotrebu, sve se svodi na literaturu iz sedamdesetih ili početak osamdesetih godina prošlog veka. Posebno je razrađena primena mera zaštite prilikom upotrebe eksploziva. / When using explosive ordnance for the demolition of elements, materials and facilities, organization is very important in the preparation of works as well as during demolition itself. In the Army of Serbia, for this kind of works, there are specialized expert units within Land Forces engineering battalions or brigades. The organization of the engineering work given in the article is a purposeful solution, regarding the use of movable property and stress imposed on people as well, when performing demolition of a concrete structure - road section. Lack of literature is a big drawback, especially lack of norms for demolition works. Except for some unofficial lectures for internal use, most of the literature dates back to the seventies or early eighties. A special emphasis in this paper is given to the application of protective measures in the use of explosives. / В процессе применения минно-взрывных средств для сноса элементов, материалов

    Praseodymium I spectral lines were investigated using laser induced fluorescence spectroscopy in a hollow cathode discharge lamp. The investigations led to the discovery of new Pr I energy levels of even and odd parity. A high resolution Fourier transform (FT) spectrum was used to extract promising excitation wavelengths. In the FT spectrum the investigated line 4375.53 A shows up as a narrow peak hfs with a weak SNR. Nevertheless, the line was excited and fluorescence signals were observed on 6 lines (4163 A, 4816 A, 5091 A, 5164 A, 5209 A, 5233 A). The hfs of the line was recorded by scanning the laser frequency and was fitted to obtain angular momentum J and hf constant A of the combining levels. We got J{sub up}=5/2, A{sub up}=1028.30 MHz, J{sub lo}=7/2 and A{sub lo}=861.46 MHz (the subscripts refer to upper and lower level). Assuming an unknown upper level, a known lower level was searched among the known levels having sufficient values of J and A. The level 7617.440 cm{sup -1}, even parity, J{sub lo}=7/2 and A{sub lo}=868 MHz fulfils these requirements. Using the center of gravity wave number of the line 4375.53 A and the energy of the lower level, the unknown upper level was calculated to have 30465.424 cm{sup -1}, odd parity, J{sub up}=5/2 and A{sub up}=1033(6) MHz.

    The state of biological dosimetry methods and prospects for their development are considered. Attention is paid to biological indicators of radiation injuries caused by nuclear weapons. It is noted, that determination of the number of lymphocytes in the blood in case of combined radiation injuries should be concerned with great care and in each case the analysis results should reffered to critically and supported by the data from other investigations. Promissing are the methods related to dermination of reticulocyte number in the peripheral blood within the irradiation dose range, causing bone marrow form of radiation syndrome, method of leukocyte adhesion and some other methods based on the change of biophysical caracteristics of cell membranes. To increase the information efficiency it is necessary to combine these methods with the methods, based on genetic change registration, and to develop a combined method.

    Full Text Available Поражение магистральных артерий нижних конечностей при сахарном диабете (СД наблюдается в 3-5 раз чаще, чем при изолированном атеросклерозе. Высказывается мнение, что существует тесная генетическая связь между СД типа 2 и атеросклеротическими процессами в артериях. Течение атеросклероза при диабете гораздо агрессивнее, у больных диабетом частота встречаемости критической ишемии примерно в 5 раз выше, чем в остальной популяции; трофические нарушения развиваются у 10% пациентов с СД в пожилом возрасте. При выявлении критической ишемии пациент с диабетом оказывается перед альтернативой потери конечности в ближайшие 6 мес. ? около 40-50% ампутаций нижних конечностей по поводу периферической артериальной недостаточности выполняется у больных диабетом. Результаты исследования Basle показали, что высокие? ампутации выполняются в 11 раз чаше при СД, чем у остальных пациентов, причем ампутации требуются у более молодых людей.

    Decisions of the highest authorities condition the welfare of society. Therefore, the issue of the racionalisation of their decisions is very important. The need to reveal the grounds of the decisions of lawmakers calls for investigating their information behaviour, i.e. their behaviour in the process of information seeking, its optimization and application in the process of decision-making. The lack of research of information behaviour (from the point of view of lawmakers rather than of info...

    The main aspects of study of the natural gamma field in the geological investigations of sea bottom are considered. Problems of development of sea scintillation radiometers for continuous (in profiles) and discrete, in (in stations) measurements of the natural gamma-radiation of the superficial layer of modern sea sediment and rock of sea bottom in conditions of natural occurence are discussed. The significance of gammametry of shallow-water zones, in the Caspian, Baltic, Black and Japan seas for the study of the geological structure of the sea bottom and its mineral base is shown. Geophysical methods are briefly described which must be used in combination with gammametry of the sea bottom. According to the Soviet and foreign sources the future of using spectrometry of natural and also induced and captured gamma radiation is shown for the study of ferro-manganese and phosphorus concretions, depressions in the sea bottom, filled by highly mineralized brines and silts.

    Effect of nonmodified and modified chalk on curing degree of polymer matrix was studied under-irradiation of PVC-compositions. Films of the compositions (100 mass part 7 PVC, 0-100 mas.part of chalk, 2.5 - lead sulfate, 1.5 - lead stearate and 0.3 - glycerin) were irradiated up to absorbed dose 0.1 MGy in an inert medium. Content of gel-fraction after boiling in THF was determined with use of IR spectroscopy. It was established, that intensive dehydrochlorination and polymer curing took place on chalk particle surface. Network fixed strongly chalk particles. However, chalk inhibited processes of dehydrochlorination and PVC curing, increasing amount of noncured PVC in polymer matrix.

    Full Text Available In Slovenia, soil research of a given landscape is often neglected in physical geography studies. Despite the fact of an equivalent position of soil geography within the science system of Slovene geography. Reasons can be found in time consuming fi eld research, expensive laboratory analysis and soil data and also the lack of its own methodology. The drawbacks could be partially replaced by different approaches of research and especially to establish links with other physical elements of the environment. The use of easily accessible digital and cartographic data, basic field techniques, in combination with simple GIS tools and quantitative methods overcomes many of the financial or time constraints.

En cambio, en el grupo sometido a la irradiacion neutronica con la dosis mas elevada, solo sobrevivio un 4% de las plantulas. No se observaron mutaciones en el grupo testigo y el numero de plantas que presentaba retonos rayados crecio al aumentar la dosis de ambos tipos de radiacion. Se observaron retoflos con mutaciones en un 15% de las plantas sobrevivientes tratadas con la dosis inferior de neutrones y la misma frecuencia se registro para la dceis mayor de rayos gamma.

    In design process of thermal power plant various ecological and economic contradictory interests are brought in focus. Requests on environmental protection written in laws, standards and international treaties are increasing investment costs and energy production costs. In a design phase there is a task to reconcile these contradictory requests. The paper presents relationship between technology and environmental protection with a focus on air pollution. Air pollution and human health is considered taking in account the role of design phase in thermal power plants project and human health problems. International laws and standards are presented with moral dilemmas concerning low investment costs and high environmental standards. (author). 6 tabs., 2 figs., 13 refs.

    Full Text Available Abstract Background Overpopulation, poor hygiene and disease prevention conditions in prisons are major structural determinants of increased infectious risk within prison settings but evidence-based national and WHO guidelines provide clear indications on how to reduce this risk. We sought to estimate the level of infectious risk by measuring how French prisons adhere to national and WHO guidelines. Methods A nationwide survey targeting the heads of medical (all French prisons and psychiatric (26 French prisons units was conducted using a postal questionnaire and a phone interview mainly focusing on access to prevention interventions, i.e. bleach, opioid substitution treatment (OST, HBV vaccination and post-exposure prophylaxis (PEP for French prisoners. Two scores were built reflecting adherence to national and WHO international guidelines, ranging from 0 (no adherence to 10 (maximum adherence and 0 to 9 respectively. Results A majority (N = 113 (66% of the 171 prisons answered the questionnaires, representing 74% coverage (46,786 prisoners of the French prison population: 108 were medical units and 12 were psychiatric units. Inmate access to prevention was poor. The median[IQR] score measuring adherence to national guidelines was quite low (4.5[2.5; 5.5] but adherence to WHO guidelines was even lower 2.5[1.5; 3.5]; PEP was absent despite reported risky practices. Unsuitable OST delivery practices were frequently observed. Conclusions A wide gap exists between HIV prevention policies and their application in prisons. Similar assessments in other countries may be needed to guide a global policy reform in prison settings. Adequate funding together with innovative interventions able to remove structural and ideological barriers to HIV prevention are now needed to motivate those in charge of prison health, to improve their working environment and to relieve French prisoners from their currently debilitating conditions.

    Introducción

    La creencia mejor respaldada actualmente nos indica que existe un grupo de enfermedades causadas por anormalidades en el procesamiento de las proteínas. En la década 1950-1960 D. Carleton Gajdusek y Vincent Zigas comenzaron a estudiar en Nueva Guinea una enfermedad fatal del sistema nervioso que se conoce con el nombre de Kuru que estaba diezmando a la tribu Fore, comunidad de unos 12.000 nativos (Figura 1. Gajdusek y Zigas observaron que el Kuru no correspondía a ningún modelo genético conocido y con la colaboración del antropólogo R. Glasse pensaron que el canibalismo ritual practicado por los Fore podría ser la causa de la transmisión de esta enfermedad, lo cual resultó cierto porque el Kuru prácticamente desapareció tras tres décadas de abolidos estos hábitos.

    Desde el primer momento se notó que el Kuru tenía características comunes con el Scrapie y que había semejanza entre estas dos entidades y la enfermedad de Creutzfeldt-Jakob (ECJ, una demencia de progresión rápida, no limitada geográficamente, descrita a principios del siglo XX, las tres aparentemente causadas por infecciones virales lentas con largos períodos de incubación medibles en años y un avance irreversible de los síntomas.

    Este pensamiento, por supuesto, se apoyaba en la afirmación formulada en 1939 por Mc Farlane Burnet de un posible mecanismo de acción lenta o temperada, inicialmente ejemplificada en los virus Herpes y en la propuesta que unos 15 años más tarde hiciera el veterinario islandés B. Sigurdsson de llamar Enfermedades Virales Lentas a las entidades que exhibieran tal comportamiento. Philip Duffy y colaboradores en la Universidad de Columbia, en 1974 comunican la primera observación de transmisión de la demencia de Creutzfeldt –Jakob de humano a humano a través de un injerto de córnea y a esta se sumaron otras posibilidades de transmitir el agente causal, entre ellas electrodos contaminados, hormona de crecimiento, transplante de duramadre. Pese a esta demostración de transmisibilidad la teoría viral desde el comienzo encontró fuerte oposición; lo cual no impidió que la comunidad científica comprendiera el alcance de esta ejemplarizante investigación y concediera por ella a DC Gajdusek el Premio Nobel de Medicina en 1976.

    El punto de partida de este monumental trabajo fue entregado a la comunidad científica desde 1981 en el libro cuya carátula vemos en la Figura 2. En 1970 J.S. Griffith y R. Latarget plantean que estos agentes infecciosos carentes de ácidos nucléicos en vez de estructura viral podrían tener naturaleza esencialmente protéica..

    Seismic characteristics for a nuclear power plant location are partly obtained from the analysis of past earthquakes. Data from older history concern damages, the newer data are in the form of seismic records. These two sources are often had to correlate, and the data dissipation is very large. Therefore these, rather unreliable data are not a convenient base for the precise anti-seismic analysis. A redistribution of efforts in order to get more reliable basic data seems necessary.

    In the book research results are generalized for processes of water supply and purification of wash water discharges from dredge mining of placer deposits. Aspects of the geological and mineralogical structure of the solid phase of dredge waste waters and regularities in its influence on the sedimentation capacity of the suspended matter are examined. On the basis of a study of distinctive features in the hydrodynamic processes occurring in dredge sludge-settling tanks, a method is proposed for calculation of the settling tank parameters, allowing their areas of application for wash water discharge clarification to be determined reliably. Results are reported for a study of methods of intensification of the deposition of suspended clay particles in dredge waste waters, (methods) based on the use of both a series of coagulants and flocculants producible by industry and various production wastes. Aspects of the theory and practice of organizing circulating water supply for dredges are examined. The influence of wash water discharges forming during placer mining on the environment is assessed.

    The aim of the experiment was to compare the growth of maize (Zea mays L.), hybrid Valentine, in two types of contaminated soil substrate (ocher and stacks) with different concentrations of arsenic (As) derived from an old mining site in Pernek in the Small Carpathians. Plants were grown in a greenhouse for 15 weeks. We found that although the total concentration of As in stacks was 2.6 times lower than in ocher (90.05 mg kg{sup -1} in stacks and 236.8 mg kg{sup -1} in ocher) the plants grown in stacks accumulated in their tissues more As compared to the plants growing in ocher. Moreover, plants in stacks were significantly smaller, they produced less biomass and bloomed later. This paradox can be explained by reduced mobility of As in ocher substrates characteristic by high content of hydro-oxides of Fe.

    Full Text Available New challenges witnessed also in Slovenian higher education requirea different approach towards understanding students and their expectations,as higher education becomes increasingly market-oriented.Since research on assessing student expectations is still rare, we havedecided to establish the expectations of students regarding their studiesat the University of Primorska. With the help of factor analysis, wehave determined that these expectations are related to the followingsix factors: relationship between teaching staff and students, faculty’sreputation, faculty’s environment, employment chances, academic excellence,and staff competence and expertise. Cluster analysis has revealeda difference between the expectations of students of professionalstudy programmes and students of academic study programmes.

    The bone marrow eosinophils of minks and wild rats subjected to chronical irradiation are able of secreting a peroxidase system obtained by neutrophils. As a result heterophilic granulocytes appear in the peripheral blood. Intercellular transgranulation, emperiopolesis into megakaryocytes and eosinophils as peroxidase donors for neutrophils are regarded as cellular and subcellular adaptations in the mammalian bone marrow after irradiation.

  12. National audit of the quality of pain relief provided in emergency departments in Aotearoa, New Zealand: The PRiZED 1 Study.

    2017-04-01

    Pain is a common feature of ED presentations and the timely provision of adequate analgesia is important for patient care. However, there is currently no New Zealand data with respect to this indicator of care quality. The present study aimed to provide a baseline for the quality of care with respect to the provision of timely and adequate analgesia in New Zealand EDs. The present study is a secondary analysis of data initially collected for the Shorter Stays in Emergency Department Study, using a retrospective chart review of 1685 randomly selected ED presentations (2006-2012) from 26 New Zealand public hospital EDs. Of the 1685 charts randomly selected, 1547 (91%) were reviewed from 21 EDs. There were 866 ED presentations with painful conditions, of whom 132 (15%) did not have pain recorded, 205 (24%) did not receive pain relief and 19 (2%) did not have time of analgesia documented leaving 510 (59%) for the analysis of time to analgesia. Four hundred and fifty-seven (53%) did not have pain well documented sufficiently to assess adequacy, leaving 277 (32%) for the analysis of adequacy of analgesia. The median (interquartile range) time to analgesia was 62 (30-134) min and the provision of adequate analgesia was 141/277 (51%, 95% CI: 45-57%); however, there was some variation between hospitals for both outcomes. Although these outcomes are on a par with other countries, this baseline audit has shown both poor documentation and variation in the provision of timely and adequate pain relief in New Zealand EDs, with room for improvement with respect to this quality indicator. © 2017 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    Full Text Available This article contains a review of the monograph by Yu.V. Seleznev published in early 2017 and dedicated to the relations of Russian princes with the Golden Horde’s khans and their status among the Golden Horde’s nobility. This work is the first comprehensive study in the historiography of this issue for all two and a half centuries of the Tartar domination. The monograph was published for the first time in 2013 and served as the basis for a doctoral dissertation, which Seleznev defended in 2015. The book was reprinted with certain changes in 2017. The book commendably contains an abundance of factual material through the use of diverse sources and strands of historiography. Seleznev examines the social terminology of Golden Horde-Russian relations, the structure of the Golden Horde’s nobility and the trips of princes to the Horde, drawing attention not only to the status of the great Vladimir and Moscow princes, but also that of other great and appanage princes. He makes a significant contribution to the resolving the debate regarding the nature of the Golden Horde’s domination in Rus’ by examining in detail the relationship of the Russian princes with the Golden Horde’s authorities in different years. The book’s author proposed to divide the Golden Horde’s “yoke” into seven periods characterized by “changes in the degree of sovereignty and jurisdiction of the khan in relation to Russian principalities”. The author of this review agrees with the main conclusions of the book under review, but at the same time he notes some reservations and criticisms, which do not, however, reduce the academic caliber of the monograph.

    Even after publication of the 2011 update of GOLD report, some fundamental questions in the management of COPD are still open and this may weaken the applicability of these guidelines in everyday clinical practice. To assess the level of consensus amongst Italian respirologists on different topics related to diagnosis, monitoring and role of bronchodilator therapy in COPD, by using the Delphi technique. A Delphi study was undertaken between July and November 2011, when two questionnaires were consecutively sent to a panel of experts to be answered anonymously. After each round, the data were aggregated at group level of question topics and structured feedback was given to the panel. A first-round questionnaire was sent to 208 pulmonologists randomly selected from different Italian regions. The 132 respondents (63% of those initially selected) were from northern (53%), central (19%) and southern (28%) Italy. A second-round questionnaire was sent to all the first-round respondents, and a response was received from 110 of them (83%). The main topics that reached the pre-defined cut off for consensus (67% or more) were: a) bronchodilator therapy with long-acting bronchodilators could be beneficial in patients with airflow limitation even in the absence of symptoms, b) in patients not fully controlled with one long-acting bronchodilator, maximizing bronchodilation (i.e. adding another bronchodilator with a different mechanism of action) is the preferable option; and c) the use of inhaled corticosteroids (ICSs) as add on therapy should be considered in severe patients with frequent exacerbations. Italian specialists agree on several aspects of the diagnosis and treatment of COPD and expert opinion could support everyday decision process in the management of COPD.

    Full Text Available In the modern society, where importance is placed on progress, newtechnologies and economic trends, there is a lack of awareness of thesignificance of good interpersonal relations and organizational culturewithin a company. They both contribute to the better functioningof employees as well as the entire organization. The purpose of thisstudy was to determine any possible differences between the stressorslinked to the relationships within an organization and those linked tothe work of middle management. The study included 58 middle managersworking in commercial activity in the Ljubljana region. The resultshave indicated that the amount of stressors related to the relationships,and stressors related to the managers’ work, that affect themiddle managers participating in the survey is on average the same.The results have therefore shown no statistically significant differencebetween the two forms of the studied stress factors.

    Natural processes that occur in the ground as a result of almost complete or partial depletion of large gas and gas-condensate deposits are analyzed. Problems concerned with the disruption of the fluid systems equilibrium are examined as represented by interstitial water and industrial gaseous and gas-condensate accumulations. Observations over a period of 20-25 years were made of the depleted deposits of North-Stavropol', Gazlin, and Shebel, whose initial hydrogeological background that serves as the basis of the reference system, has been studied in detail. Information is also presented on recently exploited water-vapor systems, such as the large Vuktyl', Orenburg, Medvezh', and Shatlyk deposits. The book is intended for a broad spectrum of geologists, hydrogeologists, and engineers interested in geology and the working of gas and gas condensate deposits. 36 references, 27 figures, 35 tables.

    The problem of relativistic electron beam-laser beat waves interaction is considered. Due to interaction the electron density is changed as opposed to the case, when it interacts with still electron plasma, the change of density gets less. But it is interesting to research the coherent spontaneous radiation of the electron beam interacting with. It is shown that this interaction brings to an increase of the partial coherent effect. The radiation efficiency depends essentially on the beam parameters, i.e. on the radio of the distinctive longitudinal dimension density. The maximum amplification takes place when the beam length makes room for an odd number of wave length quarters. Since the gain factor decreases with the radiation wave length, we offer to use high-current relativistic electron beams to generate micro radio waves. 4 refs.

By CT cerebral symptoms were divided of 4 groups. Clinical symptom complexes of CNS defects and SLE were reflected on definite CT images correlated with focal damage to the brain. CT picture of enlarged subarachnoid space, ventricles and basal cisterns can be observed in SLE patients without neurological symptoms. This indicated likely subclinical cerebral affection.

    The aim of this study is to define the practical application of the modified system for angiographic assessment of the run-off arteries after reconstruction below the inguinal ligament suggested by Schwierz T. 137 patients with infrainguinal arterial reconstructions were followed up for a period of 1 year. The blood volume was measured distally from the distal graft anastomosis by means of flow meter (VeriQ, Medistim, Oslo, Norway). The flowmetry was performed before and after a 5-minute Prostavasin or llomedin intragraft infusion, causing peripheral vasodilatation. The data was compared with the minimal expected debit which was assessed according to the Schwirz system. During the follow up period in the group of the non properly functioning bypasses we registered lack of coincidence in 37% between the preoperatively assessed and the intraoperatively measured minimal blood flow concerning the compromised bypasses. In the group of the properly functioning bypasses the lack of coincidence was only 6% probably due to subjective false assessment of minor collaterals. Taking into consideration the subjective pattern of the angiographic assessment system and the importance of the high quality angiographic imaging we believe that the preoperatively assessed expected blood flow is not applicable in means of long term prognosis but may be used as an additional indicator for the condition of the run-off arteries as well as the short term results of the operative treatment.

    Thermal stability of the radiation defects produced in KBr-In by optical creation of the electronic excitation (optical creation of the excitons or optical ionization of In{sup +}-ions under C-band illumination) is investigated by the method of thermostimulated luminescence (TSL). A method of detection of prehistory defects, when the optical ionization of In{sup +}-ions and TSL are performed, is proposed. Quadratic dependence of V{sub 2}-center creation upon dose is shown. This dependence confirms assocative mechanism of the creation of V{sub 2}-centers from two interstitial centers.

    Full Text Available Ta prispevek se ukvarja s tem, kako mestni prebivalci dojemajo upravljanje okolja in varovanje okolja v narodnih parkih, zlasti v Jugovzhodni Evropi, in kakšen odnos imajo do teh vprašanj. Dejavniki, ki sodobne turiste spodbujajo k obisku narodnih parkov, pogosto niso jasni. Sodobne družboslovne raziskave se jim ne posvečajo dovolj. Zato smo preučili profil in potrebe urbanih obiskovalcev narodnega parka Pelister v Republiki Makedoniji. Zanimalo nas je, v kolikšni meri je njihovo zanimanje za naravne značilnosti območja pristno oziroma površno in simbolno. Izsledki so pokazali, da je zanimanje urbanih obiskovalcev predvsem površno. To razkriva potrebo po razvoju učinkovite strategije za odnos do obiskovalcev, ki bo sestavni del splošnega upravljanja narodnih parkov.

    Popularnost Facebooka je v zadnjih nekaj letih izrazito narastla, vendar kljub temu njegov vpliv na partnerske odnose še zmeraj ostaja relativno neraziskan. Magistrsko delo ugotavlja, kako je uporaba Facebooka povezana z ljubosumjem in nadzorom partnerja na Facebooku ter z zadovoljstvom v samem partnerskem odnosu. Ker pa je romantična ljubezen proces navezanosti, se nam je prav tako zdelo pomembno, da v empiričnem delu raziščemo povezavo med različnimi stili navezanosti in ljubosumjem na Face...

    Catalytic processes induced by radiation in the presence of non-metallic solids are discussed, attention being given exclusively to the effects associated with modification of the steady state concentration of charge carriers. The effect of such modification on the kinetics and equilibrium of heterogeneous reactions is quantitatively estimated within the framework of the electronic theory of catalysis, due regard being paid to the electronic characteristics of the surface of the solid. In conclusion, the relationship between these phenomena, catalyst activation and transfer of energy, as previously described, is discussed.

    Full Text Available In the article the author deals with the question which substantive tax rules that determine a taxpayer and tax liability (tax debt should apply in cases where these rules change from the time a taxable event takes place and until the tax is self-assessed of levied, if the legislator has not prescribed anything in the transitional provisions in this respect. Since the Slovenian tax legislation has no general provisions for such cases, the jurisprudence has decided to either apply the provisions that were in force at the date that tax obligation occurred or provisions that were in force during the tax period to which the tax liability relates. The author is a bit critical of that position because he finds it inadequate to some extent. Therefore he suggests an amended interpretation which takes into account provisions of the Slovenian constitution and practice of the Slovenian Constitutional Court. In conclusion, the author proposes an amendment of the Slovenian tax legislation with the enactment of a general provision that would resolve such legal situations.

    The detection of gamma-emitting radionuclides at environmental levels in biological media requires that the sensitivity of the counting system be high. To accumulate sufficiently precise data, it is often necessary to count samples for long periods of time - from one to several hours. The most efficient utilization of expensive low-background gamma-ray spectrometric counting equipment requires that it be operated on a continuous basis. This necessitates either the continuous presence of personnel or a completely automated system, including the changing of samples and recording of data. The purpose of this paper is to describe the automated gamma-ray spectrometry counting system designed, built and in use at the Northeastern Radiological Health Laboratory, Winchester, Massachusetts. The sample changing unit was designed to operate in conjunction with a large steel shield, any commercial unit with a front opening door being readily adaptable for this purpose. The changer is equipped to handle a variety of samples including biological and medical types. The unit consists of a revolving tray with a capacity for sixteen samples, an indexing system for positioning the samples, a mechanical arm with an attached electromagnet for inserting and removing the samples from the shield, and a lever for opening and closing the shield door. The changer has been completely integrated with a multichannel analyser with the provision of safety features to interrupt the cycle in case of malfunction at any step. After a preset counting period, the data are punched onto paper tape and processed by an IBM. 1620 computer. The first model of the sample changer, for which a patent is pending, has been in operation at the Northeastern Radiological Health Laboratory for about one year. During that time, it has been used extensively and has proven completely satisfactory. The total cost of the unit, including labour, was less than $ 2000.

Pour tirer le meilleur parti possible de l'appareil de comptage par spectroscopie gamma a faible mouvement propre qui est couteux, il faut l'utiliser sans interruption. Cela suppose la presence continue de personnel ou une complete automatisation comprenant le changement des echantillons et l'enregistrement des donnees.

Le changeur d'echantillons est coupje a une enceinte blindee en acier, n'importe quelle enceinte blindee en vente dans le commerce avec porte sur le devant pouvant etre facilement adaptee a cette fin. Le changeur est capable de manipuler toute une variete d'echantillons, notamment des echantillons biologiques et medicaux. Il est constitue par un plateau rotatif destine a recevoir 16 echantillons, un dispositif code de positionnement des echantillons, un bras mecanique muni d'un electro-aimant qui introduit les echantillons dans l'enceinte et les en retire, et d'un levier automatique commandant l'ouverture et la fermeture de la porte de l'enceinte.

Ademas, para lograr datos suficientemente precisos es necesario que el tiempo de recuento sea relativamente largo, a saber, de una a varias horas. Para utilizar con la mayor eficacia posible el equipo de recuento de espectrometria gamma de baja actividad de fondo, que es sumamente costoso, conviene hacerlo funcionar en forma continua durante 24 h al dfa. Para ello se requiere personal que lo atienda constantemente o un sistema de recuento enteramente automatico incluso para el cambio de muestras y el registro de los datos. En esta memoria se describe el sistema automatizado de recuento por espectroscopia gamma disenado, construido y utilizado en el Northeastern Radiological Health Laboratory de Winchester, Massachusetts. El cambiador de muestras funciona en conjuncion con un blindaje de acero que no necesita ser especial; cualquiera de los comerciales, si esta provisto de una puerta frontal, puede ser adaptado al cambiador. Dicho cambiador puede adaptarse a diversos tipos de muestras, incluidas las biologicas y medicas. Consta de una bandeja giratoria con capacidad para 16 muestras; un sistema localizador para las muestras; un brazo mecanico, con electroiman, para introducir o retirar las muestras desde el exterior, y una palanca para abrir y cerrar la puerta blindada. El cambiador se ha integrado completamente con un analizador multicanal provisto de dispositivos de seguridad que interrumpen el ciclo cuando se produce una averfa en cualquier punto.

    The development of the formulae of perturbation theory provides a good opportunity to use one of the principal devices of mathematical heuristics, i.e. proceeding by analogy from something that is simple to something that is more complicated. This paper: (a) Reviews the formulation of perturbation theory as a method of calculating reactivity coefficients; this consists mainly of developing the differential equation for the adjoint flux, as a continuous function of position and lethargy, by proceeding by analogy from the one-group differential equation for adjoint flux. (b) Presents an application of the two-group form of perturbation theory to a boiling-mercury-cooled fast-breeder reactor (MCBR). It is seen that the net Hg density coefficient of reactivity for the first-design-try for the MCBR is negative for some regions and positive for others. However, it is negative for regions of highest statistical weight and where the density change for a power change would be the greatest. The overall Hg density coefficient is thus negative, i.e. the void coefficient is positive-an unsafe condition. It can be easily seen from the two-group formulation what design changes had to be made to obtain a design which would have a negative void coefficient. It developed in subsequent investigations that there were such design changes that could be made and a design of the MCBR with a negative void coefficient was eventually achieved. (author) [French] La mise au points des formules de la theorie des perturbations fournit une bonne occasion d'employer en mathematiques une des principales regles de la methode heuristique, celle qui consiste a proceder par analogie du simple au complexe. L'auteur du memoire: a) Expose une methode permettant de calculer les coefficients de reactivite en utilisant les formules de la theorie des perturbations; en substance, cette methode consiste a developper l'equation differentielle relative au flux adjoint en fonction continue de la position et de la lethargie, en procedant par analogie a partir de l'equation differentielle a un groupe relative au flux adjoint. b) Montre comment appliquer la forme a deux groupes de la theorie des perturbations au cas d'un reacteur surgenerateur a neutrons rapides, refroidi au mercure. Lors de l'essai preliminaire du reacteur, on a constate que la variation de reactivite accompagnant une variation de densite du mercure est telle que le coefficient net de la reactivite est negatif pour certaines regions et positif pour d'autres. Il est negatif pour les regions de poids statistique le plus eleve et ou une variation de puissance entrainerait le changement de densite le plus important. Le coefficient global de densite du mercure est donc negatif, et par consequent le coefficient cavitaire est positif, ce qui est dangereux. On peut facilement voir, en employant la forme a deux groupes, quelles modifications doivent etre apportees aux plans du reacteur etudie pour obtenir un coefficient cavitaire negatif. Au cours de recherches ulterieures, il s'est revele possible d'apporter certaines de ces modifications, et l'on est finalement parvenu a etablir des plans tels que le coefficient cavitaire du reacteur soit negatif. (author) [Spanish] Las formulas de la teoria de las perturbaciones pueden establecerse empleando uno de los procedimientos mas importantes de la heuristica matematica, que consiste en partir de una expresion sencilla para llegar por analogia a una expresion mas compleja. La presente memoria: (a) Formula la teoria de las perturbaciones como metodo para calcular los coeficientes de reactividad. Consiste principalmente en desarrollar la ecuacion diferencial del flujo adjunto como funcion continua de la posicion y del letargo, procediendo por analogia a partir de la ecuacion diferencial de un solo grupo para el flujo adjunto. (b) Presenta una aplicacion de la forma de dos grupos de la teoria de las perturba ciones a un reactor reproductor rapido, refrigerado por mercurio hirviente (MCBR). Al calcular la reactividad, se comprueba que el coeficiente correspondiente a la densidad neta del mercurio en el primer proyecto del MCBR es negativo en algunas regiones, y positivo en otras. Es negativo en las regiones de peso estadistico maximo y en las que los cambios de densidad serian mayores al variar la potencia. Por lo tanto, el coeficiente global de densidad del mercurio es negativo, esto es, el coeficiente de vacios es positivo, lo que constituye una condicion que implica peligro. En la formulacion de dos grupos, se aprecia facilmente que modificaciones es preciso introducir en el diseno para que el coeficiente de cavidad sea negativo. Nuevas investigaciones demostraron que era posible introducir dichas modificaciones, lograndose establecer para el MCBR un diseno cuyo coeficiente de vacios es negativo.

These studies have taken the form of the measurement of the. angular distributions of electrons and protons with respect to the spin direction of the decaying free neutrons. The basic components of the apparatus which will be discussed are: 1. The one-meter iron-cobalt mirror which selects a beam of highly polarized neutrons and the methods for determination of the polarization. 2. The electron detector comprising a 10 cm diameter, 6 mm thick mosaic of anthracene crystals, and its light pipe system. 3. The proton detector, a 14-stage electron multiplier system, the first stage with a 15x15 cm opening, tapering in four stages to a standard 10-stage multiplier structure, and its entrance baffles for angular resolution. 4. The electronic system which selects pulses from the detectors having the proper time sequence, relative time-delay and pulse-height to allow indentification of a neutron decay.

    Full Text Available Article 4 of the Unified Customs and Practices of Documentary Letters of Credit establishes the notion of autonomy principle by separating credit from underlying contract between account party and beneficiary. Article 5 by recognizing the autonomy principle confirms that effectuate the payment under credit, banks only deal with documents and not with goods. As a result, while documentary letters of credit are meant to facilitate the process of international trade, their sole dependency on compliance of presented documents to bank by beneficiary to actualize the payment will increase the risk of fraud and forgery in the course of their operation. Interestingly, UCP (currently UCP600 takes a silent status regarding the problem of fraud in international LC operation and leaves the ground open for national laws to provide remedies to affected parties by fraudulent beneficiary. National Laws have different approaches to the problem of fraud in general and fraud in international LC operation in particular which makes the access of affected parties to possible remedies complicated and difficult. Current paper tries to find answer to the questions of (i what available remedies are provided to affected parties in international LC fraud by different legal systems? (ii And what are conditions for benefiting from such remedies under different legal systems? In achieving its objective, paper will be divided in two main parts to study remedies provided by intentional legal frameworks as well as the ones offered by national laws. Part one will study the position of UCP and UNCITRAL Convention on Independent Guarantees and Standby Letters of Credit (UNCITRAL Convention and remedies, which they provide to LC fraud in international trade. Part two in contrary will study available remedies to LC fraud and condition for access them under English and American legal system.

    The experience gained in the All-Russian Research Institute of NPP Operation (RU) in improvement of reactor start-up and normal operation of NPPs has been reported. The work was carried out on NPPs in Russia, Ukraine, Bulgaria, Hungary and Czechoslovakia. All scientific programmes applied use the system approach, modern methods of safety assessment and the principle of loss effect optimization. For the Kozloduy NPP the following projects have been implemented: design of accelerated unloading system for WWER-1000; refinement of water feeding unit for the WWER-1000 steam generator; response analysis of the safety anti-breakdown system of the second loop. The importance of technical substantiation in the process of decision making is stressed. 6 refs.

    Full Text Available Machine translation is a field in computational linguistics that explores the use of software to translate text from one language to another. Factored statistical translation is an extension of statistical machine translation, where linguistic annotation is added on the word level. Words are turned into vectors in an attempt to improve translation quality. We describe the use of the open-source Moses system for factored statistical machine translation from English to Slovenian. We created several factored and non-factored language and translation models from a text corpus, containing IT-related texts. We translated two different IT-related documents. The first one was marketing-orientated with a complex structure, while the second one was technical with a simpler structure. We used two methods to compare the generated translations with two independent human translations and a translation, created by the Google Translate service. The first comparison method was the BLEU metrics and the second one were evaluations of human reviewers. The latter method expressed a subjective score, which is still very important in the machine translation field. Even though the results can’t be compared directly due to different metrics, the movement of the grades is well correlated for both texts. The only bigger difference can be seen while implementing factored models for translating the second text. In the conclusion we analysed the inter-evaluator coherence and the obtained results. We discovered that our models are more suitable for technical texts, and that factored models improve the translation of complex texts more.

    The history of the development of the 4 {pi} counting method is reviewed. The unique properties of the 4 {pi} counter system are described and the criteria are specified which place disintegration rate measurements, made with the system, on an absolute basis. The types of radioactive decay process to which the method is applicable are outlined, together with the various errors to which a given measurement is liable. Departure of response probability from unity, absorption of radiation in the source-mounting system, and source self-absorption are discussed in detail.

    Gastric cancer (GC) is a multistep complex disease involving multiple genes, and gene-gene interactions have a greater effect than a single gene in determining cancer susceptibility. This study aimed to explore the interaction of the let-7e rs8111742, miR-365b rs121224, and miR-4795 rs1002765 single nucleotide polymorphisms (SNPs) with SNPs of the predicted target gene PGC and Helicobacter pylori status in GC and atrophic gastritis (AG) risk. Three miRNA SNPs and seven PGC SNPs were detected in 2448 cases using the Sequenom MassArray platform. Two pairwise combinations of miRNA and PGC SNPs were associated with increased AG risk (let-7e rs8111742 - PGC rs6458238 and miR-4795 rs1002765 - PGC rs9471643). Singly, miR-365b rs121224 and PGC rs6912200 had no effect individually but in combination they demonstrated an epistatic interaction associated with AG risk. Similarly, let-7e rs8111742 and miR-4795 rs1002765 SNPs interacted with H. pylori infection to increase GC risk (rs8111742: Pinteraction = 0.024; rs1002765: Pinteraction = 0.031, respectively). A three-dimensional interaction analysis found miR-4795 rs1002765, PGC rs9471643, and H. pylori infection positively interacted to increase AG risk (Pinteraction = 0.027). Also, let-7e rs8111742, PGC rs6458238, and H. pylori infection positively interacted to increase GC risk (Pinteraction = 0.036). Furthermore, both of these three-dimensional interactions had a dosage-effect correspondence (Ptrend < 0.001) and were verified by MDR. In conclusion, the miRNAs SNPs (let-7e rs8111742 and miR-4795 rs1002765) might have more superior efficiency when combined with PGC SNPs and/or H. pylori for GC or AG risk than a single SNP on its own.

    The possibility is examined of development of interferences in information circuits of RP and AP with their convergence with lines powering micromotors used in control circuits. It is indicated that with start-up of the micromotors in the information circuits, adjustments can be made which exceed in level and duration the operating signal. Results are presented of experimental measurements and interferences in the circuit of block signalling of the EPP. A technique is obtained for calculating the developed interferences.

    Full Text Available En este artículo se revisa la problemática reciente de la seguridad en la agenda pública de Nuevo León. Se destaca el efecto en los resultados electorales para el partido gobernante, tanto en elecciones intermedias como en la sucesión por la gubernatura. En ese sentido, el periodo de gobierno de 2003 a 2009 tuvo que enfrentar los altos índices delictivos con promulgación de leyes y políticas públicas, para marcar una reestructuración institucional en esta área. Se encontró evidencia de que el partido gobernante perdió espacios en los comicios intermedios en un contexto de gran inseguridad, pero esto no repercutió en la sucesión por la gubernatura, aunque los índices de homicidios por narcotráfico y la percepción de inseguridad ciudadana fueron altos hasta el término de la administración.

    Full Text Available Fires in the operational underground mine openings, as a rule, are catastrophic and lead to numerous victims. Due to the transfer of combustion products by the ventilation stream of the mine ventilation, they can be spread over long distances from the fire site and mortally injure miners along the course of the air stream. Essential assistance to miners in such emergency situations is provided by means of individual protection of miners, which are breathing apparatus of various types - so-called self-rescuers. There are cases anyway when they cannot protect from poisonous combustion products action. Then in the arsenal of mine rescuers there must be medical preparations capable of restoring the respiratory functions of the miners the fire victims. The purpose of this article is to familiarize mining specialists and VGSCh workers with the current state of medical preparations for carbon monoxide effect neutralization.

    The relaxation of the electron beam with the electron density of 1-2 keV injected through the symmetrically open plasma system with the independent hot cathode Penning discharge is experimentally investigated. It is shown that the velocity distribution function of the electron beam changes after passing each wave generation zone induced by the beam. The contribution of different wave zones to the beam relaxation depends on the prehistory of the beam-plasma interaction and may be regulated by the selection of the plasma system parameters. By this way the complete relaxation of the electron beam can be achieved after the beam crossing the whole system.

    Large scale electronic phase separation (EPS) between ferromagnetic metallic and charge-ordered insulating phases in La 5/8-y Pr y Ca 3/8 MnO 3 (y = 0.3) (LPCMO) is very sensitive to the structural changes. This work investigates the effects of post-annealing on the strain states and electrical transport properties of LPCMO films epitaxially grown on (001) pc SrTiO 3 (tensile strain), LaAlO 3 (compressive strain) and NdGaO 3 (near-zero strain) substrates. Before annealing, all the films are coherent-epitaxial and insulating through the measured temperature range. Obvious change of film lattice is observed during the post-annealing: the in-plane strain in LPCMO/LAO varies from −1.5% to −0.1% while that in LPCMO/STO changes from 1.6% to 1.3%, and the lattice of LPCMO/NGO keeps constant because of the good lattice-match between LPCMO and NGO. Consequently, the varied film strain leads to the emergence of metal-insulator transitions (MIT) and shift of the critical transition temperature in the electrical transport. These results demonstrate that lattice-mismatch combined with post-annealing is an effective approach to tune strain in epitaxial LPCMO films, and thus to control the EPS and MIT in the films

    Critical boron concentration before and after postulated loss of coolant accident with long-term cooling recirculation was calculated for cycle 6 of Krsko NPP. The limiting boron concentration curve of containment sump was calculated for equilibrium conditions. The results were analysed and showed that the boron concentration in refueling water storage tank and in safety injection accumulators should be increased from 2000 to 2100 ppm in 6th cycle. In the consequence corresponding chapters of the NPP Krsko technical Specifications were changed as well. (author)

    Upon demand of the Laboratory for fuel reprocessing, six domestic metal uranium pellets were exposed to neutron flux ( 4 - 5 10{sup 12} n cm{sup -2} sec {sup -1}) in the RA reactor. Irradiation of fuel demanded special analyses for safety reasons. Weight of the fuel pellets was 13 - 20 g, having diameter 20 mm. pellets were placed in leak tight aluminium capsules with helium. The irradiation was dome in the aluminium experimental channel in the graphite reflector. Theoretical study has shown that the expected fuel temperature in the core could be up to 300 deg C at nominal power. For that reason temperature of the capsule with the uranium sample was measured during irradiation by using thermocouples. Results showed the discrepancy between measure and calculated values to be about 30%.

    del lecho del rio. Desde este punto de vista, el tritio posee excelentes propiedades, puesto que no es absorbido, pero es dificil de medir y no es posible seguir directamente su desplazamiento en el rio. Otros indicadores resultan mas convenientes, pero pueden sufrir adsorcion. Los autores han estudiado los grados de adsorcion del {sup 24}Na, {sup 82}Br y {sup 32}P en forma de NaHC0{sub 3}, NH{sub 4}Br y NaH{sub 2}PO{sub 3} respectivamente, que introdujeron en un mismo punto del rio junto con agua tritiada (HTO), para comparar despues las mediciones realizadas en varios lugares situados aguas abajo. Se ha visto que el EP, para el que se esperaban grandes perdidas por quimisorcion, no sirve para medir el caudal de rios cuando se emplea sin portador, aunque el error disminuye notablemente cuando se trabaj a con portador. En el caso del {sup 24}Na y del {sup 32}Br, no se observa adsorcion a distancias mucho mayores que la requerida para que la mezcla lateral sea satisfactoria si bien a una distancia de 660 m en el rio de corriente mas lenta se observo que parte del {sup 24}Na habia desaparecido. Los autores formulan algunas observaciones sobre el grado de dispersion lateral y longitudinal que tienen importancia para la aplicacion de tecnicas radioisotopicas en general a la medicion del caudal de rios.

    stomatal conductance during the treatment. At the end of the experiment, N accumulation and 15N recovery was highest in FI, intermediate in PRI and lowest in DI. In addition, PRI plants consistently allocated more N into the upper and middle leaf layers than in the FI and DI treatments. The improved N...... nutrition and distribution in the canopy may indicate that PRI plants have a greater photosynthetic capacity than DI plants; this is confirmed by the observed positive linear relationship between specific leaf N content and δ13C. It is concluded that PRI improves N nutrition and optimises N distribution...

  20. Expression of genes for microRNA-processing enzymes is altered in advanced non-alcoholic fatty liver disease.

    Recently, microRNAs (miRNA) have been linked to the pathogenesis of non-alcoholic fatty liver disease (NAFLD) and its progression to non-alcoholic steatohepatitis (NASH). First transcribed as pri-miRNA, these molecules are further processed by a complex of endonuclear and cytosolic RNA binding molecules to form mature miRNAs. The aim of this study is to investigate mechanisms of miRNA regulation in the visceral adipose of obese NAFLD patients via measuring expression of miRNA processing enzymes and pri-miRNA. Total RNAs were extracted from visceral adipose tissue (VAT) samples collected from patients undergoing bariatric surgery. All patients had biopsy-proven NAFLD (NASH patients [n = 12] and non-NASH NAFLD [n = 12]). For each patient, we profiled mRNA levels for three miRNA processing elements (Drosha, DGCR8, and Dicer1) and seven pri-miRNAs (pri-miR-125b-2, pri-miR-16-2, pri-miR-26a-1, pri-miR-26a-2, pri-miR-7-1, pri-miR-7-2, and pri-miR-7-3). Expression of Dicer1, Drosha and DGCR8 was significantly increased within the NASH cohort along with expression of pri-miR-7-1. The presence of focal necrosis on the liver biopsy correlated significantly with levels of Dicer1 and DGRC8. Both NASH and ballooning degeneration of hepatocytes correlated negatively with the expression levels of hsa-miR-125b. Histologic NASH correlated positively with the expression levels of pri-miR-16-2 and pri-miR-7-1. The presence of the hepatocyte's ballooning degeneration in the liver biopsy correlated positively with pri-miR-26a-1 and pri-miR-7-1. The expression profile of pri-miR-125b-2 also correlated positively with body mass index. Our findings support the hypothesis that VAT-derived miRNA may contribute to the pathogenesis of NASH in obese patients. © 2013 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

    Full Text Available The article offers the theoretical concepts and methodological guidelines for research on  historical stereotypes of the major European theorists from the various social science disciplines. For us, an important theoretical and methodological interpretation of  ethnic and other stereotypes was formulated by Professor Hans Hening Hahn, as well as other Central European researchers. We use the presented theoretical and methodological guidelines to analyse the stereotype of Slovakian diligence. The primary sources of the textual analysis are ethnographic travelogues and diverse literature of Slovak origin, which are  rich sources for scientific interpretation of stereotypes. Writers resorted to an idealization and generalization of character, physical appearance and other characteristics of the population of Ungarn and the Habsburg monarchy, and so there were constructed ethnic/national, cultural, confessional, gender, as well as other auto/heterostereotypes. We deal with the stereotype of Slovak diligence, with specific attention to the situation in which they were formulated, we point out their tasks and the reciprocal interaction with other auto- and heterostereotypes.

Acetylene-1, 2-C{sup 14} is converted successively to tetrachloroethane and trichloroethylene, and this is condensed with carbon tetrachloride by the Prins reaction in the presence of aluminium chloride to octachlorocyclopentene. Dechlorination gives hexachlorocyclopentadiene which undergoes a Diels-Alder addition to bicyclo(2, 2, 1) hepta-2,5-diene to give aldrin-C{sup 14} in 12% yield from barium carbonate. Oxidation of Aldrin gives the 6,7 epoxide, Dieldrin, in 87% yield. The paper includes an account of the separation of octachlorocyclopentene from the crude product of the Prins reaction by gas-liquid chromatography and of the separation of Aldrin and Dieldrin on a small preparative scale by reversed-phase paper chromatography.

    The wear rate of grinding balls used in ball mills is usually hard to determine under operational conditions and little is known-about the factors determining ball life. Radioactive tracers have been used successfully to mark cast steel balls to obtain information on their life under various operating conditions for comparison with balls of different type or composition. A batch of marked steel balls has been followed through a milling operation over several weeks and statistics on wear and loss of weight have been obtained. In the test runs cobalt-60 was added to the molten metal before casting and the balls were then observed in use at an iron mine. The radioactive batch was added to a ball mill with a normal charge of about 75 tons and the mill charge was sampled at weekly intervals to pick out active balls. These balls were inspected and weighed, and the wear rate has been calculated. This procedure has proved to be a practical way of investigating wear properties under plant operating conditions.

    The safety of the Kozloduy NPP is being promoted by backfitting and improved operational practice. Special measures mitigating potential severe accidents consequences are needed because of some deficiencies in the original design of the four WWER-440 units. In conditions of a total LOCA (Loss Of Coolant Accident) it is impossible to ensure decay heat removal using the existing safety system. In such cases an extra emergency feedwater system independent of the plant`s other systems has been introduced which offers a new alternative means of removing the residual heat from the reactor. A probabilistic safety analysis is carried out using the method of event trees. A comparison between the existing safety system and the newly proposed is made. The simulation results of the unit behaviour prove that the damage frequency of the active zone is lower with the new system. 3 refs., 3 tabs., 2 figs.

    Analysis of the results of clinicopsychological investigation of persons developing ARS (1-3 degree of severity) as a result of the Chernobyl accident has shown that 4-6 mos. after the exposure the psychic status and mental working ability of the affected persons showed close correlation with a degree of ARS. In 12-18 mos. profession and adequate employment played a decisive role in the formation of unfavorable psychic conditions and limited working ability. Later on in 2.5-3 years after exposure a decrease in psychic working ability, the development of unfavorable psychic conditions was noted more frequently in patients with ARS of more severe types and in examinees of older age. At all stages of rehabilitation personality traits of the affected persons play an important role in the revival of working abilities.

    As a result of interpreting space photographs, lineaments were revealed of a regional nature of northwest, northeast, sublatitudinal and submeridional directions. Individual large lineaments which were active recently correspond to faults of the latest activation belonging to deep structures. Statistical processing of the data of their extent established the main and secondary systems, and among them the screening and intersecting pools. Analysis of the arrangement of oil and gas fields, directions of lineaments and motion of groundwater made it possible to establish five main hydrodynamic types of pools, four of which belong to displaced groundwater. In selecting the direction for prospecting for oil and gas in order to determine efficient arrangement of wells, it is recommended that orientation of the promising systems of lineaments and motion of groundwater be taken into consideration.

    The paper deals with the preparation of the radionuclide {sup 212}Pb by emanation and its further application in the study of adsorption processes in bentonite rocks. Chronic toxicity of Pb, as of one of the oldest contaminants, causes disturbances in reproductive behaviour, brain damage, neurological disorders, kidney activity damage and many others. {sup 212}Pb has radiogenic origin, it belongs to a series of {sup 232}Th and considering its short half-time time its occurrence is linked primarily to Th. Emanation is a suitable method for preparation of {sup 212}Pb, as a subsidiary radionuclide of a decay series of {sup 232}Th. Due to the electric field at a voltage of 310 V the {sup 212}Pb was captured from Th-source on niobium emanator sheets. Then it leached from there into HNO{sub 3} solution. After adjusting the pH solution and sample preparation there took place a radioindicator study of the effect of mixing time of solid and liquid phase on adsorption percentage of Pb. Adsorption of Pb was studied on bentonite from Slovakian deposits Lieskovec in relation to their use as a tightening barrier of different landfill sites. (authors)

    Mangrove forest is an important component of wetland ecosystems, which has high productivity, strong carbon sequestration capacity and great ecological values. The light use efficiency (LUE) of photosynthesis is a major parameter for estimating plant productivity. Recent studies have shown that the photochemical reflectance index (PRI) has a strong relationship with LUE and the relationship is significantly influenced by plant species and environmental factors. In this paper, we evaluated the relationship between PRI and LUE for different mangrove species (Avicennia marina and Aegiceras corniculatum) and the effects of Spartina alterniflora invasion on the PRI-LUE relationship. The results showed that the LUE of mangroves had a good correlation with PRI, and the correlation of Avicennia marina was stronger than that of Aegiceras corniculatum. In addition, the invasion of Spartina alterniflora impaired the PRI-LUE relationship for both mangrove species.

  19. Biological Evaluation of Double Point Modified Analogues of 1,25-Dihydroxyvitamin D2 as Potential Anti-Leukemic Agents

    Full Text Available Structurally similar double-point modified analogues of 1,25-dihydroxyvitamin D2 (1,25D2 were screened in vitro for their pro-differentiating activity against the promyeloid cell line HL60. Their affinities towards human full length vitamin D receptor (VDR and metabolic stability against human vitamin D 24-hydroxylase (CYP24A1 were also tested. The analogues (PRI-1730, PRI-1731, PRI-1732, PRI-1733 and PRI-1734 contained 5,6-trans modification of the A-ring and of the triene system, additional hydroxyl or unsaturation at C-22 in the side chain and reversed absolute configuration (24-epi at C-24 of 1,25D2. As presented in this paper, introduction of selected structural modifications simultaneously in two distinct parts of the vitamin D molecule resulted in a divergent group of analogues. Analogues showed lower VDR affinity in comparison to that of the parent hormones, 1,25D2 and 1,25D3, and they caused effective HL60 cell differentiation only at high concentrations of 100 nM and above. Unexpectedly, introducing of a 5,6-trans modification combined with C-22 hydroxyl and 24-epi configuration switched off entirely the cell differentiation activity of the analogue (PRI-1734. However, this analogue remained a moderate substrate for CYP24A1, as it was metabolized at 22%, compared to 35% for 1,25D2. Other analogues from this series were either less (12% for PRI-1731 and PRI-1733 or more (52% for PRI-1732 resistant to the enzymatic deactivation. Although the inactive analogue PRI-1734 failed to show VDR antagonism, when tested in HL60 cells, its structure might be a good starting point for our design of a vitamin D antagonist.

    The carbon science community must rely on satellite remote sensing to obtain global estimates of photosynthetic activity, typically expressed as net primary production (NPP), gross primary production (GPP) or light use efficiency (LUE). The photochemical reflectance index (PRI), calculated as a normalized difference reflectance index using a physiologically active green band (~531 nm) and another physiologically insensitive green reference band (~570 nm), denoted as PRI(570), has been confirmed in many studies as being strongly related to LUE. Here, we examined the potential of utilizing PRI(570) observations under different illumination conditions for canopy LUE estimation of a forest. In order to evaluate this, directional hyperspectral reflectance measurements were collected continuously throughout the daytime periods using an automated spectroradiometer in conjunction with tower-based eddy covariance fluxes and environmental measurements at a coastal conifer forest in British Columbia, Canada throughout the 2006 growing season. A parameter calculated as the PRI(570) difference (dPRI(570)) between shaded versus sunlit canopy foliage sectors showed a strong correlation to tower-based LUE. The seasonal pattern for this correlation produced a dramatic change from high negative (r ~ -0.80) values in the springtime and early fall to high positive values (r ~ 0.80) during the summer months, which could represent the seasonality of physiological characteristics and environmental factors. Although the PRI(570) successfully tracked canopy LUE, one or both of its green bands (~531 and 570 nm) used to calculate the PRI are unavailable on most existing and planned near-term satellites. Therefore, we examined the potential to use 24 other spectral indexes for LUE monitoring that might be correlated to PRI, and thereby a substitute for it. We also continued our previous investigations into the influence of illumination conditions on the observed PRI(570) and other indexes

    The carbon science community must rely on satellite remote sensing to obtain global estimates of photosynthetic activity, typically expressed as net primary production (NPP), gross primary production (GPP) or light use efficiency (LUE). The photochemical reflectance index (PRI), calculated as a normalized difference reflectance index using a physiologically active green band (∼531 nm) and another physiologically insensitive green reference band (∼570 nm), denoted as PRI(570), has been confirmed in many studies as being strongly related to LUE. Here, we examined the potential of utilizing PRI(570) observations under different illumination conditions for canopy LUE estimation of a forest. In order to evaluate this, directional hyperspectral reflectance measurements were collected continuously throughout the daytime periods using an automated spectroradiometer in conjunction with tower-based eddy covariance fluxes and environmental measurements at a coastal conifer forest in British Columbia, Canada throughout the 2006 growing season.

  2. Remote Sensing of Light Use Efficiency in a Boreal Forest and Peatland in James Bay, Quebec

    The photochemical reflectance index (PRI) is a remotely sensed vegetation index that detects a decrease in spectral reflectance at 531nm associated with xanthophyll cycle activity. PRI has been shown to track light use efficiency (LUE) in a number of plant species. PRI shows great promise in improving our ability to sense photosynthetic fluxes of CO2 remotely. However, it has not been tested in all environments, and its applicability is particularly uncertain for peatland environments dominated by mosses. This research investigates the ability of PRI to track LUE in a boreal forest and peatland, and examines the spectral signal associated with xanthophyll cycle activity in heterogeneous peatland plots. This research also investigates the relationship between PRI and leaf area index (LAI) over space and time in a peatland. We found most plots examined in the peatland site did not exhibit a spectral signal associated with xanthophyll cycle activity when exposed to a transition from dark conditions to full sunlight. This transition should lead to a de-epoxidation of xanthophylls in leaf tissues and a decrease in reflectance at 531nm. Plots that did show the decrease in reflectance at 531nm after this change in light conditions also displayed a decrease in PRI. This indicates that PRI effectively detects the 531nm signal as well as xanthophyll cycle activity and light stress in these plots. However, the variability in the strength of the spectral response to changing light conditions may confound the PRI signal in practice, and make it difficult to interpret results of airborne or satellite data. We also found PRI at the peatland site to be sensitive to and directly correlated with spatial variability in LAI, and negatively correlated with temporal variability in LAI. These characteristics may result in further difficulties applying PRI in peatlands. PRI and LUE were correlated at both the forest and peatland site, however at both sites the PRI signal saturated around

    Geometric isomers (5E,7E) of major active metabolites of vitamin D3 [1alpha,25(OH)2D3 and (24R)-1,24(OH)2D3] were synthesized by a new convenient procedure. Vitamin D triene system of the metabolites was first derivatized as a Diels-Alder adduct. Removal of the triene protecting group, in a key synthetic step, yielded the title compounds PRI-2208 and PRI-2209, respectively. The analogs were examined for their antiproliferative activity in vitro against human breast cancer cells (MCF-7) and promyelocytic leukemia (HL-60) cells. The activity was compared with one of the parent compounds. Both analogs examined revealed similar or higher antiproliferative activity compared to 1alpha,25(OH)2D3 or to (24R)-1,24(OH)2D3. The studies of calcemic activity in vivo showed that analogs PRI-2208 and PRI-2209 did not influence the serum calcium level in doses, in which 1alpha,25(OH)2D3 or (24R)-1,24(OH)2D3 significantly increased this level. The antitumor activity of these analogs in the LLC mice tumor model was studied. Analog PRI-2208 was found to be more active in inhibiting LLC tumor growth than 1alpha,25(OH)2D3, as well as than PRI-2191 and PRI-2209. Copyright (c) 2010 Elsevier Ltd. All rights reserved.

    Chronic hepatitis C virus (HCV) infection is one of the major causes of serious liver diseases, including liver cirrhosis. There are no anti-fibrotic drugs with efficacy against liver cirrhosis. Wnt/β-catenin signaling has been implicated in the pathogenesis of a variety of tissue fibrosis. In the present study, we investigated the effects of a β-catenin/CBP (cyclic AMP response element binding protein) inhibitor on liver fibrosis. The anti-fibrotic activity of PRI-724, a selective inhibitor of β-catenin/CBP, was assessed in HCV GT1b transgenic mice at 18 months after HCV genome expression. PRI-724 was injected intraperitoneally or subcutaneously in these mice for 6 weeks. PRI-724 reduced liver fibrosis, which was indicated by silver stain, Sirius Red staining, and hepatic hydroxyproline levels, in HCV mice while attenuating αSMA induction. PRI-724 led to increased levels of matrix metalloproteinase (MMP)-8 mRNA in the liver, along with elevated levels of intrahepatic neutrophils and macrophages/monocytes. The induced intrahepatic neutrophils and macrophages/monocytes were identified as the source of MMP-8. In conclusion, PRI-724 ameliorated HCV-induced liver fibrosis in mice. We hypothesize that inhibition of hepatic stellate cells activation and induction of fibrolytic cells expressing MMP-8 contribute to the anti-fibrotic effects of PRI-724. PRI-724 is a drug candidate which possesses anti-fibrotic effect.

  5. Microprocessor Recruitment to Elongating RNA Polymerase II Is Required for Differential Expression of MicroRNAs

    Directory of Open Access Journals (Sweden)

    2017-09-01

    Full Text Available The cellular abundance of mature microRNAs (miRNAs is dictated by the efficiency of nuclear processing of primary miRNA transcripts (pri-miRNAs into pre-miRNA intermediates. The Microprocessor complex of Drosha and DGCR8 carries this out, but it has been unclear what controls Microprocessor’s differential processing of various pri-miRNAs. Here, we show that Drosophila DGCR8 (Pasha directly associates with the C-terminal domain of the RNA polymerase II elongation complex when it is phosphorylated by the Cdk9 kinase (pTEFb. When association is blocked by loss of Cdk9 activity, a global change in pri-miRNA processing is detected. Processing of pri-miRNAs with a UGU sequence motif in their apical junction domain increases, while processing of pri-miRNAs lacking this motif decreases. Therefore, phosphorylation of RNA polymerase II recruits Microprocessor for co-transcriptional processing of non-UGU pri-miRNAs that would otherwise be poorly processed. In contrast, UGU-positive pri-miRNAs are robustly processed by Microprocessor independent of RNA polymerase association.

    Full Text Available Abstract Background MicroRNAs (miRNAs are important regulators of gene expression and have been implicated in development, differentiation and pathogenesis. Hundreds of miRNAs have been discovered in mammalian genomes. Approximately 50% of mammalian miRNAs are expressed from introns of protein-coding genes; the primary transcript (pri-miRNA is therefore assumed to be the host transcript. However, very little is known about the structure of pri-miRNAs expressed from intergenic regions. Here we annotate transcript boundaries of miRNAs in human, mouse and rat genomes using various transcription features. The 5' end of the pri-miRNA is predicted from transcription start sites, CpG islands and 5' CAGE tags mapped in the upstream flanking region surrounding the precursor miRNA (pre-miRNA. The 3' end of the pri-miRNA is predicted based on the mapping of polyA signals, and supported by cDNA/EST and ditags data. The predicted pri-miRNAs are also analyzed for promoter and insulator-associated regulatory regions. Results We define sets of conserved and non-conserved human, mouse and rat pre-miRNAs using bidirectional BLAST and synteny analysis. Transcription features in their flanking regions are used to demarcate the 5' and 3' boundaries of the pri-miRNAs. The lengths and boundaries of primary transcripts are highly conserved between orthologous miRNAs. A significant fraction of pri-miRNAs have lengths between 1 and 10 kb, with very few introns. We annotate a total of 59 pri-miRNA structures, which include 82 pre-miRNAs. 36 pri-miRNAs are conserved in all 3 species. In total, 18 of the confidently annotated transcripts express more than one pre-miRNA. The upstream regions of 54% of the predicted pri-miRNAs are found to be associated with promoter and insulator regulatory sequences. Conclusion Little is known about the primary transcripts of intergenic miRNAs. Using comparative data, we are able to identify the boundaries of a significant proportion of

    1998-01-01

    A fully characterised natural rubber latex was subjected to mechanical degradation by stirring at intervals. The resistance to oxidative degradation of the different samples were studied by measuring the Plasticity retention indices (PRI).The results show that there is an enhancement of the PRI from 57% for the undegraded rubber to 79% for the one-hour degraded sample. Further degradation resulted in decrease of PRI as time of degradation increased. Therefore, the one-hour degraded sample is a special rubber with high oxidation resistance which is of great importance in engineering.

    The concept of light use efficiency (Epsilon) and the concept of fraction of photosynthetically active ration (PAR) absorbed for vegetation photosynthesis (PSN), i.e., fAPAR (sub PSN), have been widely utilized to estimate vegetation gross primary productivity (GPP). It has been demonstrated that the photochemical reflectance index (PRI) is empirically related to e. An experimental US Department of Agriculture (USDA) cornfield in Maryland was selected as our study field. We explored the potential of integrating fAPAR(sub chl) (defined as the fraction of PAR absorbed by chlorophyll) and nadir PRI (PRI(sub nadir)) to predict cornfield daily GPP. We acquired nadir or near-nadir EO-1/Hyperion satellite images that covered the cornfield and took nadir in-situ field spectral measurements. Those data were used to derive the PRI(sub nadir) and fAPAR (sub chl). The fAPAR (sub chl) is retrieved with the advanced radiative transfer model PROSAIL2 and the Metropolis approach, a type of Markov Chain Monte Carlo (MCMC) estimation procedure. We define chlorophyll light use efficiency Epsilon (sub chl) as the ratio of vegetation GPP as measured by eddy covariance techniques to PAR absorbed by chlorophyll (Epsilon(sub chl) = GPP/APAR (sub chl). Daily Epsilon (sub chl) retrieved with the EO-1 Hyperion images was regressed with a linear equation of PRI (sub nadir) Epsilon (sub chl) = Alpha × PRI (sub nadir) + Beta). The satellite Epsilon(sub chl- PRI (sub nadir) linear relationship for the cornfield was implemented to develop an integrated daily GPP model [GPP = (Alpha × PRI(sub nadir) + Beta) × fAPAR (sub chl) × PAR], which was evaluated with fAPAR (sub chl) and PRI (sub nadir) retrieved from field measurements. Daily GPP estimated with this fAPAR (sub chl-) PRI (nadir) integration model was strongly correlated with the observed tower in-situ daily GPP (R(sup 2) = 0.93); with a root mean square error (RMSE) of 1.71 g C mol-(sup -1) PPFD and coefficient of variation (CV) of 16

    The logistics network design is one of the important phase of Supply Chain Management (SCM) and it is the problem that should be optimized for long-term promotion of efficiency of the whole supply chain. Usually a plant produces different type of products. Even if it is a factory of the same company, delivery is different by a kind of a produced product. The restrictions which this model has are deeply concerned with TP in the real world. In this paper, we consider the logistics network design problems with multi-products and constraints for delivery course. To solve the problem, we used a hybrid priority-based Genetic Algorithm (h-priGA), and we tried the comparison experiment with priority-based Genetic Algorithm (priGA)and h-priGA, we show it about the effectiveness of h-priGA.

    The objective of this study was to investigate the comparative effects of alternative partial root-zone irrigation (PRI) and deficit irrigation (DI) on fertilizer-N use efficiency in tomato plants under mineral N and organic N fertilizations. The plants were grown in split-root pots in a climate......-controlled glasshouse and were subjected to PRI and DI treatments during early fruiting stage. When analyzed across the N fertilizer treatments, PRI treatment led to significantly higher N yield, agronomic N use efficiency (ANUE), and apparent N recovery efficiency (ANRE) as compared with the DI treatment, indicating...... significantly higher fertilizer-N use efficiency and soil N availability as well as enhanced plant’s N acquisition ability in the PRI treatment. Analysis across the irrigation treatments showed that the mineral N fertilizer treatment (MinN) significantly increased N yield, ANUE and ANRE relative to the organic...
