RIP-Chip analysis supports different roles for AGO2 and GW182 proteins in recruiting and processing microRNA targets.
2019
Background MicroRNAs (miRNAs) are small non-coding RNA molecules mediating the translational repression and degradation of target mRNAs in the cell. Mature miRNAs are used as a template by the RNA-induced silencing complex (RISC) to recognize the complementary mRNAs to be regulated. To discern further RISC functions, we analyzed the activities of two RISC proteins, AGO2 and GW182, in the MCF-7 human breast cancer cell line. Methods We performed three RIP-Chip experiments using either anti-AGO2 or anti-GW182 antibodies and compiled a data set made up of the miRNA and mRNA expression profiles of three samples for each experiment. Specifically, we analyzed the input sample, the immunoprecipita…
Evaluation of Chemical Composition of Essential Oils Derived from Different Pelargonium Species Leaves
2019
Abstract Plants have been used for their aromatic and medicinal purposes for centuries. The genus Pelargonium contains about 250-280 species and cultivated around the world for the production of essential oils and absolutes. Pelargonium species are remarkable for their odour diversity, from fresh, lemon and minty scent, through floral, rose, fruity up to spicy and camphoreous smell as well as many health beneficial properties, that is why their essential oils are widely used in perfume, cosmetic, food and pharmaceutical industries. The aim of this study was to determine variability in populations of Pelargonium genus by evaluating their differences in quantitative and qualitative essential …
Laser-Induced Plasma Emission Spectrometric Study of Pigments and Binders in Paper Coatings: Matrix Effects
1998
Laser-induced plasma emission spectroscopy (LIPS) has been used to study inorganic pigment and organic binder distributions in paper coatings, which are inhomogeneous and porous materials. The plasma was generated by focusing a pulsed XeCl excimer laser beam (diameter 100 μm, irradiance 0.3 GW/cm2) on the sample surface at atmospheric pressure. A gated intensified CCD detector was used to record time-delayed emission spectra. Linear correlations between the LIPS signals and the coat weight and the binder content of the coatings studied were obtained. Emission line intensities from ionic and neutral magnesium atoms were used to evaluate plasma temperature corrections in determining silicon a…

The Self between Vehicle Externalism and the Myth of the Cartesian Theatre
2011
Il saggio esamina il dilemma proposto da Andy Clark secondo il quale o accettiamo gli argomenti di parità per la conclusione che il sé può essere in parte costituito da strutture ambientali, o siamo implicitamente impegnati al Mito del teatro Cartesiano. Si criticano in primo luogo gli argomenti di parità di Clark perché riducono e assimilano le relazioni vigenti tra organismo e strutture ambientali al livello personale - mediate da coscienza e intenzionalità – alle relazioni causali autorganizzanti che mediano il reclutamento e mantenimento delle risorse interne. Si critica quindi la tesi di Clark secondo la quale l’internalismo sarebbe necessariamente impegnato al Mito del Teatro Cartesia…
Dark matter results from 225 live days of XENON100 data
2012
We report on a search for particle dark matter with the XENON100 experiment, operated at the Laboratori Nazionali del Gran Sasso (LNGS) for 13 months during 2011 and 2012. XENON100 features an ultra-low electromagnetic background of (5.3 \pm 0.6) \times 10^-3 events (kg day keVee)^-1 in the energy region of interest. A blind analysis of 224.6 live days \times 34 kg exposure has yielded no evidence for dark matter interactions. The two candidate events observed in the pre-defined nuclear recoil energy range of 6.6-30.5 keVnr are consistent with the background expectation of (1.0 \pm 0.2) events. A Profile Likelihood analysis using a 6.6-43.3 keVnr energy range sets the most stringent limit o…
Theoretical absorption spectrum of the Ar–CO van der Waals complex
2003
The three-dimensional intermolecular electric dipole moment surface of Ar–CO is calculated at the coupled cluster singles and doubles level of theory with the aug-cc-pVTZ basis set extended with a 3s3p2d1f1g set of midbond functions. Using the rovibrational energies and wave functions of our recent study [J. Chem. Phys. 117, 6562 (2002)], temperature-dependent spectral intensities are evaluated and compared to available experimental data. Based on the theoretical spectrum, alternative assignments of the experimentally observed lines in the fundamental band of CO around 2160 and 2166 cm−1 are suggested. Thomas.Bondo@uv.es
Relative Transition Probability Measurements for Prominent Infrared Spectral Lines of NI
2002
Applying a high-current wall-stabilized arc operated either in helium or in argon always with some admixtures of nitrogen, relative transition probabilities for more than 100 individual spectral lines (fine structure components) have been measured. The studied lines belong mainly to the 3p–3d and 3p–4s transition arrays. Ten lines of the measured set are intersystem transitions. Our data are compared with other experimental results (for about one half of the studied set there are available), with evaluated on the basis of the LS coupling scheme, with semiempirical data, and with recent CIV3 calculations. Some of our results are compared also with experimental data for the next member of the…
Le langage célinien dans Mort à crédit
2011
Työ käsittelee ranskalaisen kirjailijan Louis-Ferdinand Célinen kieltä ja kielenkäyttöä kirjassa Mort à crédit. Sen suomenkielinen versio on nimeltään Kuolema luotolla, joka on kirjailijan läpimurtoteoksen (Voyage au bout de la nuit, Niin kauas kuin yötä riittää) seurannut omaelämäkerrallinen teos. Työssä tarkastellaan kirjailijalle tavanomaisia piirteitä kuten lyhyet ja katkonaiset lauseet, kolme pistettä, huutomerkit, onomatopoeettiset sanat, mutta ennen kaikkea omaperäinen sanasto. Tässä työssä sanastollisesti tarkastelun kohteeksi on valittu sanat, jotka viittaavat naisiin. Näistä on koottu taulukko, mistä käy ilmi sanan laatu (neutraali, posiitiivinen vai negatiivinen) ja myös tehty ve…
