description: We compute the tree-level connected four-point function of the primordial curvature perturbation for a fairly general minimally coupled single field inflationary model, where the inflaton's Lagrangian is a general function of the scalar field and its first derivatives. This model includes K-inflation and DBI-inflation as particular cases. We show that, at the leading order in the slow-roll expansion and in the small sound speed limit, there are two important tree-level diagrams for the trispectrum. One is a diagram where a scalar mode is exchanged and the other is a diagram where the interaction occurs at a point, i.e. a contact interaction diagram. The scalar exchange contribution is comparable to the contact interaction contribution. For the DBI-inflation model, in the so-called equilateral configuration, the scalar exchange trispectrum is maximized when the angles between the four momentum vectors are equal and in this case the amplitude of the trispectrum from the scalar exchange is one order of magnitude higher than the contact interaction trispectrum.

description: Inimese immuunpuudulikkuse viiruse (HIV) epideemia Eestis jätkub. Uute juhtude arv püsib suur ning on liikunud riskirühmadest tavainimeste hulka. Infektsiooni leviku tõkestamiseks ja tervishoiukulude vähendamiseks tuleks patsiente HIV suhtes analüüsida ja leida üles võimalikult palju nakatunuid. See annaks võimaluse alustada neil õigel ajal antiretroviirusravi (ARV-ravi). Varane ARV-ravi aitab ära hoida viirusega seotud komplikatsioonide tekkimist ning vähendab nakatumisriski.Eesti Arst 2015; 94(9):547–550

description: Allergiline silmahaigus on ülitundlikkusreaktsioon, mis haarab tavaliselt ainult silmi, kuid kaasneda võivad ka muud sümptomid. Klassikalisteks allergilisteks konjunktiviitideks peetakse hooajalist ning aastaringset allergilist konjunktiviiti, atoopilist keratokonjunktiviiti ja vernaalset ehk kevadkeratokonjunktiviiti. Tekkemehhanismid on atoopilisel ja vernaalsel konjunktiviidil aga teised kui hooajalisel ning aastaringsel allergilisel konjunktiviidil. Allergiliste silmahaiguste diagnoosimisel tuleb toetuda täpse anamneesi võtmisele ja haiguse kliinilistele ilmingutele. Nii farmakoloogilise kui ka immuunraviga on võimalik haigestunu sümptomeid leevendada. Patsiendi teadlikkus ning allergeenide vältimine on nende haiguste puhul esmatähtsad.Eesti Arst 2015; 94(9):551–558

An electron spin resonance study of nitro-substituted naphthalene anion radicals and ion-pairs

Publisher: name: University of British Columbia
Year: 2011

description: The radical anions and ion-pairs of 1,8-dinitro-naphthalene and 1,4,5,8-tetranitronaphthalene have been perpared and the electron spin resonance spectra have been investigated in detail. The spectra were interpreted completely in terms of a set of two equivalent nitrogen atoms and three sets of two equivalent hydrogen atoms for the 1,8-dinitronaphthalene radical, four equivalent nitrogen atoms and four equivalent hydrogen atoms for the 1,4,5, 8-tetranitronaphthalene radical, respectively. The hyper-fine splitting constants obtained are compared with the values derived from molecular orbital calculations. In the ion-pairs of 1,8-dinitronaphthalene the distinct alkali metal hyperfine splitting have been observed The magnitude of the metal hyperfine splitting shows remarkable temperature dependency, and the temperature dependence is interpreted in terms of the cation exchange mechanism b between two nitro groups of 1,8-dinitronaphthalene. In the anion radical of 1,8-dinitronaphthalene as well as in the corresponding ion-pairs, anormalous line width variation has been observed. This behaviour is interpreted in terms of the cation exchange mechanism and supports the hypothesis proposed for the temperature dependence of alkali metal splitting in the ion-pairs of the compound. In the anion radical of 1,4,5,8-tetranitronaphtha-lene the twisting angle of the nitro group from the plane of aromatic ring is estimated to be (35 ±10)° from the observed splitting constants by employing the spin densities obtained with McLachlan method. The temperature dependency of the nitrogen and hydrogen splittings has been determined. The phenomenon is explained in terms of a hindered rotation of.the nitro group in 1,4,5,8-tetranitronaphthalene. From the asymmetry of the spectra it is predicted that the spin density on the nitrogen nucleus is positive.
Frustrated Magnetic Interactions, Giant Magneto-Elastic Coupling, and Magnetic Phonons in Iron-Pnictides

description: We present a detailed first principles study of Fe-pnictides with particular emphasis on competing magnetic interactions, structural phase transition, giant magneto-elastic coupling and its effect on phonons. The exchange interactions $J_{i,j}(R)$ are calculated up to $\approx 12 $Å$. We find that $J_{i,j}(R)$ has an oscillatory character with an envelop decaying as $1/R^3$ along the stripe-direction while it is very short range along the diagonal direction and antiferromagnetic. A brief discussion of the neutron scattering determination of these exchange constants from a single crystal sample with orthorhombic twinning is given. The lattice parameter dependence of the exchange constants, $dJ_{i,j}/da$ are calculated for a simple spin-Peierls like model to explain the fine details of the tetragonal-orthorhombic phase transition. We then discuss giant magneto-elastic effects in these systems. We show that when the Fe-spin is turned off the optimized c-values are shorter than experimetnal values by 1.4 Å$ $ for CaFe$_2$As$_2$, by 0.4 Å$ $ for BaFe$_2$As$_2$, and by 0.13 Å$ $ for LaOFeAs. Finally, we show that Fe-spin is also required to obtain the right phonon energies, in particular As c-polarized and Fe-Fe in-plane modes. Since treating iron as magnetic ion always gives much better results than non-magnetic ones and since there is no large c-axis reduction during the normal to superconducting phase transition, the iron magnetic moment should be present in Fe-pnictides at all times. We discuss the implications of our results on the mechanism of superconductivity in these fascinating Fe-pnictide systems.

description: Uncertainty principles for generating systems $\{e_n\}_{n=1}^{\infty} \subset \ltwo$ are proven and quantify the interplay between $\ell^r(\N)$ coefficient stability properties and time-frequency localization with respect to $|t|^p$ power weight dispersions. As a sample result, it is proven that if the unit-norm system $\{e_n\}_{n=1}^{\infty}$ is a Schauder basis or frame for $\ltwo$ then the two dispersion sequences $Δ(e_n)$, $Δ(\bar{e_n})$ and the one mean sequence $μ(e_n)$ cannot all be bounded. On the other hand, it is constructively proven that there exists a unit-norm exact system $\{f_n\}_{n=1}^{\infty}$ in $\ltwo$ for which all four of the sequences $Δ(f_n)$, $Δ(\bar{f_n})$, $μ(f_n)$, $μ(\bar{f_n})$ are bounded.

description: A consistent theory to describe the correlated dynamics of quantum mechanical itinerant spins and semiclassical local magnetization is given. We consider the itinerant spins as quantum mechanical operators, whereas local moments are considered within classical Lagrangian formalism. By appropriately treating fluctuation space spanned by basis functions, including a zero-mode wave function, we construct coupled equations of motion for the collective coordinate of the center-of-mass motion and the localized zero-mode coordinate perpendicular to the domain wall plane. By solving them, we demonstrate that the correlated dynamics is understood through a hierarchy of two time scales: Boltzmann relaxation time when a non-adiabatic part of the spin-transfer torque appears, and Gilbert damping time when adiabatic part comes up.

description: Plasmonic gratings and nano-particle arrays in a metal-insulator-metal structures are fabricated on an erbium doped silicon nitride layer. This material system enables simple fabrication of the structure, since the active nitride layer can be directly grown on metal. Enhancement of collected emission of up to 12 is observed on resonance, while broad off-resonant enhancement is also present. The output polarization behavior of the gratings and nano-particle arrays is investigated and matched to plasmonic resonances, and the behavior of coupled modes as a function of inter-particle distance is also discussed.

description: We revisit sneutrino dark matter in light of the recent results from the PAMELA and ATIC experiments. In the U(1)_B-L extension of the minimal supersymmetric standard model the right-handed sneutrino is a natural candidate for thermal dark matter. Sneutrino annihilation at the present time can be considerably enhanced due to the exchange of the lightest field in the Higgs sector that breaks U(1)_B-L. The annihilation mainly produces taus (or muons) by the virtue of B-L charges. A sneutrino mass in the 1-2 TeV range provides a good fit to the PAMELA data and a reasonable fit to the ATIC data. Within this mass range the sneutrino-nucleon elastic scattering cross section is 10^(-11) - 10^(-9) pb, which might be probed by upcoming and future direct detection experiments. In addition, if (at least) one of the neutrinos is dominantly a Dirac fermion, the sneutrino can provide a unified picture of dark matter and inflation.

description: The observational basis for asteroseismology is being dramatically strengthened, through more than two years of data from the CoRoT satellite, the flood of data coming from the Kepler mission and, in the slightly longer term, from dedicated ground-based facilities. Our ability to utilize these data depends on further development of techniques for basic data analysis, as well as on an improved understanding of the relation between the observed frequencies and the underlying properties of the stars. Also, stellar modelling must be further developed, to match the increasing diagnostic potential of the data. Here we discuss some aspects of data interpretation and modelling, focussing on the important case of stars with solar-like oscillations.

Chemiluminescence of indolyl peroxides

description: Indolyl hydroperoxides have been discovered to be chemiluminescent in presence of potassium t-butoxide in dimethyl sulphoxide. A number of derivatives of indole and the corresponding peroxide have been prepared in an effort to elucidate the mechanism of chemiluminescence of this class of compound. The chemiluminescent reaction of two of the brightest hydroperoxides (X11A and XV111A) yielded a major product, the amides (Xlla and XVllla), in about 70% yield. The emitter has been identified as the amide product based on spectroscopic data. It was found that electron-donating substituents enhance the chemiluminescence intensity. A study of 2-(p-phenyl) substituted indolyl hydroperoxides shows a Hammett correlation with δ for 7 of the compounds. The chemiluminescence of compounds (XllA and (XV111A) shows a pseudo first order dependence on the concentration of (X11A and XV111A) (in excess base). Energy transfer has been observed to occur in the thermochemiluminescence of 11-tetrahydroperoxyindolenine (XXVA).

description: We demonstrate an atomic interferometer based on ultra-cold atoms released from an optical lattice. This technique yields a large improvement in signal to noise over a related interferometer previously demonstrated. The interferometer involves diffraction of the atoms using a pulsed optical lattice. For short pulses a simple analytical theory predicts the expected signal. We investigate the interferometer for both short pulses and longer pulses where the analytical theory break down. Longer pulses can improve the precision and signal size. For specific pulse lengths we observe a coherent signal at times that differs greatly from what is expected from the short pulse model. The interferometric signal also reveals information about the dynamics of the atoms in the lattice. We investigate the application of the interferometer for a measurement of $h/m_A$ that together with other well known constants constitutes a measurement of the fine structure constant.

description: In order to understand the cosmic ray propagation mechanism in galaxies, and its correlation with the sites of star formation, we compare the spatially resolved radio spectral index of three spiral galaxies with their IR distribution. We present new low-frequency radio continuum observations of the galaxies NGC 0628, NGC 3627, and NGC 7331, taken at 327 MHz with the Very Large Array. We complemented our data set with sensitive archival observations at 1.4 GHz and we studied the variations of the radio spectral index within the disks of these spiral galaxies. We also compared the spectral index distribution and the IR distribution, using 70 $μ$m Spitzer observations. We found that in these galaxies the non-thermal spectral index is anticorrelated with the radio brightness. Bright regions, like the bar in NGC 3627 or the circumnuclear region in NGC 7331, are characterized by a flatter spectrum with respect to the underlying disk. Therefore, a systematic steepening of the spectral index with the increasing distance from the center of these galaxies is observed. Furthermore, by comparing the radio images with the 70 $μ$m images of the Spitzer satellite we found that a similar anticorrelation exists between the radio spectral index and the infrared brightness, as expected on the basis of the local correlation between the radio continuum and the infrared emission. Our results support the idea that in regions of intense star formation the electron diffusion must be efficient. The observed anticorrelation between radio brightness and spectral index, may imply that the cosmic ray density and the magnetic field strength are significantly higher in these regions than in their surroundings.

description: Recently Han and Heary proposed an approach to steady-state quantum transport through mesoscopic structures, which maps the non-equilibrium problem onto a family of auxiliary quantum impurity systems subject to imaginary voltages. We employ continuous-time quantum Monte-Carlo solvers to calculate accurate imaginary time data for the auxiliary models. The spectral function is obtained from a maximum entropy analytical continuation in both Matsubara frequency and complexified voltage. To enable the analytical continuation we construct a kernel which is compatible with the analytical structure of the theory. While it remains a formidable task to extract reliable spectral functions from this unbiased procedure, particularly for large voltages, our results indicate that the method in principle yields results in agreement with those obtained by other methods.

description: The term governance describes structures and processes for the intentional steering of collective societal matters, typically addressed in concurrence by actors of state, economy and civil society. In the German-speaking community, the term “regional governance”, which corresponds to „local governance” in the English language, is well-established in the spatial sciences. The purpose of this work is to display and newly systematize the state of knowledge about regional governance. Therefore, possibilities for empirical research as well as restrictions for impact analyses are elaborated. Up to now, there is no common and generally acknowledged definition of governance. To enable a clear use of the term, an overview of critical estimations surrounding the term governance will be given. This involves methodological problems as well as blind spots in theoretical approaches. Against this background, a separate definition of regional governance is established. The examination of impact interdependencies within regional governance shows that for a comprehensive impact model, a kind of a meta theory would be needed. However, such a model is not possible due to its high degree of complexity. In fact, there is a double-sided complexity as it is necessary to regard the impact interdependencies of the governance arrangements themselves as well as of regional development as a whole. In addition, characteristic phases of governance processes must be taken into an account. Possible explanations of impact relations are derived from success factors.

description: Little Higgs models are often endowed with a T-parity in order to satisfy electroweak precision tests and give at the same time a stable particle which is a candidate for cold dark matter. This type of models predicts a set of new T-odd fermions in addition to the heavy gauge bosons of the Little Higgs models, which may show interesting signatures at colliders. In this paper, we study the signatures of strong and electroweak pair production of the first two generations of T-odd quarks at the LHC. We focus on the dileptonic signatures (p p to l l j j MET) with (a) opposite-sign dileptons and (b) same-sign dileptons.

description: We study the consistency of a model which includes torsion as well as the metric as dynamical fields and has massive spin-2 particle in its spectrum. The massive spin-2 mode resides in the torsion, rather than in the metric. It is known that this model is tachyon- and ghost-free in Minkowski background. We show that this property remains valid and no other pathologies emerge in de Sitter and anti-de Sitter backgrounds, with some of our results extending to arbirary Einstein space backgrounds. This suggests that the model is consistent, at least at the classical level, unlike, e.g., the Fierz--Pauli theory.

description: When oxygen is passed through a microwave discharges, the oxygen atoms being destroyed by distilling mercury through the discharges an excited molecule O₂(¹△g) was observed to be the primary discharge product. This excited molecule was found to be immune to collisional deactivation by a wide range of added foreign gasses, with the exception of certain substituted ethylenes which it oxidized. The principal mode of decay of O₂(¹△g) was nonradiative decay, with knonrad. equal to 0,178 sec.-¹ The excited molecule O₂(¹△g) however, was observed to undergo two novel energy pooling processes, [ Formulas omitted ] The first of these energy pooling processes gave rise to two broad structureless bands at 6340 A and 7030 A which had not previously been observed in discharged oxygen. These bands, the intensity of which is proportional to the square of the O₂(¹△g) concentration and independent of the total pressure in the systems are believed to result from a simultaneous electronic transition in two O₂(¹△g) molecules with the emission of a single photon. The 6340 A band appears if both molecules undergo a (0-0) transition in the [ Formula omitted ] system and the 7030 A. band if one molecule undergoes a (0-0) transition and the other a (0-1) transition. The second of these energy pooling processes is a disproportionation reaction which leads to the formation of a second excited molecule [ Formula omitted ]. Tne rate constant, for this reaction was found to be 1.3 x 10³ l.moles -¹sec.-¹, in disagreement with the results of Young and Black by a factor of 10⁴ Both energy pooling processes are believed to have a common intermediate, { O₂(¹△g) }2, which is either a metastable double molecule or a colliding pair of molecules. The principal mode of decay of [ Formula omitted ]was nonradiative decay, with knonrad. equal to 64.6 sec.-¹ Unlike O₂(¹△g) , [ Formula omitted ] was found to be collisionally deactivated by a wide variety of added foreign gases, with the most effective deactivator tried being water. The rate constants for the reaction [ Formula omitted ] were determined for fourteen different quenchers. A good correlation between quenching efficiency and the magnitude of the intermolecular potential between the quencher and [ Formula omitted ] has been obtained. Two additional energy pooling processes involving excited oxygen molecules and either molecular iodine or nitrogen dioxide were observed. Both resulted in the formation of an excited molecule[ Formula omitted ]or NO₂, which emitted in the visible.

description: Tugev äkkpeavalu (TÄP) on peavalu, mis algab järsku ning on maksimaalselt tugev just peavalu esimestel hetkedel. Sekundaarne TÄP võib osutuda mitme eluohtliku ajuhaiguse esmaseks ning paljudel juhtudel ka ainsaks sümptomiks, näiteks subarahnoidaalne hemorraagia, hoiatav peavalu, tserebraalne venoosne siinustromboos, kaela arterite dissektsioon, spontaanne koljusisene hüpotensioon, hüpofüüsi apopleksia, isheemiline insult, äge hüpertensiivne kriis jt harvemad põhjused. Visualiseerivate uurimismeetodite kasutamine TÄPi diagnostikas on obligatoorne. Primaarset TÄPi saab diagnoosida olukorras, kui esineb sündroomile omane tüüpiline peavalu, kuid uuringute tulemusena (visualiseerivad, laboratoorsed) puuduvad seda põhjustada võivad orgaanilised seisundid.

description: Sooletrakti mikroflooral on tähtis osa tasakaalustatud immuunreaktsioonide tekkes. See, missuguste mikroobidega laps koloniseerub, sõltub suurem määral sellest, missuguste mikroobidega ta puutub kokku kohe pärast sündi, aga ka dieedist, rakendatud antibakteriaalsest ravist jm. Soolefloora mõjutab nii kaasasündinud kui ka omandatud immuunmehhanisme, nii humoraalset kui ka rakulist immuunsust. Viimastel aastakümnetel on pööratud väga palju tähelepanu probiootikumidele, nende võimele vältida ja ravida mitmeid haigusi. Probiootikumidena kasutatakse väga erinevaid baktereid, kuid kõigil neil ei ole võrdsed raviomadused ja vähetähtis ei ole asjaolu, et ühele sobib üks, teisele teine.

description: We show that an applied charge current in a magnetic nanowire containing domain walls (DWs) results in an interaction between DWs mediated by spin-dependent interferences of the scattered carriers. The energy and torque associated with this interaction show an oscillatory behaviour as a function of the mutual DWs orientations and separations, thus affecting the DWs' arrangements and shapes. Based on the derived DWs interaction energy and torque we calculate DW dynamics and uncover potential applications of interacting DWs as a tunable nano-mechanical oscillator. We also discuss the effect of impurities on the DW interaction.

Inverse Compton X-rays from relativistic flare electrons and positrons

description: In solar flares, inverse Compton scattering (ICS) of photospheric photons might give rise to detectable hard X-ray photon fluxes from the corona where ambient densities are too low for significant bremsstrahlung or recombination. Gamma-ray lines and continuum in some large flares imply the presence of the necessary ~100 MeV electrons and positrons, the latter as by-products of GeV energy ions. Recent observations of coronal hard X-ray sources in particular prompt us to reconsider here the possible contribution of ICS. We aim to evaluate the ICS X-ray fluxes to be expected from prescribed populations of relativistic electrons and positrons in the solar corona. The ultimate aim is to determine if ICS coronal X-ray sources might offer a new diagnostic window on relativistic electrons and ions in flares. We use the complete formalism of ICS to calculate X-ray fluxes from possible populations of flare primary electrons and secondary positrons, paying attention to the incident photon angular distribution near the solar surface and thus improving on the assumption of isotropy made in previous solar discussions. Both primary electrons and secondary positrons produce very hard ICS X-ray spectra. The anisotropic primary radiation field results in pronounced centre-to-limb variation in predicted fluxes and spectra, with the most intense spectra, extending to the highest photon energies, expected from limb flares. Acceptable numbers of electrons or positrons could account for RHESSI coronal X/gamma-ray sources. Some coronal X-ray sources at least might be interpreted in terms of ICS by relativistic electrons or positrons, particularly when sources appear at such low ambient densities that bremsstrahlung appears implausible.

description: Puukentsefaliit (PE) on viirushaigus ja Eestis üks kõige sagedamini esinev neuroinfektsioon kevadsuvisel hooajal. Inimene on viiruse leviku ahelas juhuslik vahe peremees, kuid võib haigestuda eluohtlikult. Eestis on PEd aastatel 1999–2006 registreeritud 12 kuni 20 haigusjuhtu 100 000 inimese kohta aastas, mida on enam kui Lääne-Euroopas. Nakatumine toimub puugihammustuse järel või nakatunud piima tarbimisel. Haiguse inkubatsiooniperiood on 2–28 päeva, seejärel ilmnevad gripi sarnased sümptomid, mis kestavad 3–4 päeva. Paari nädala pärast järgneb tõsisem haigestumine kas meningiidi, meningoentsefaliidi, entsefalomüeliidi või polüradikulo  neuriidina. Puukentsefaliidi ravi on sümptomaatiline. Viirushaiguse põdemine annab eluaegse immuunsuse. Tõhus profülaktika on vaktsineerimine.

description: Disclosed are then inorganic membranes having a defined topography that includes pores having a defined diameter of nanometer and sub-nanometer diameter. The thin membranes are resistant to protein denaturing agents, and may be employed in analytical and clinical methods for identifying single amino acid residues within the sequence of a protein and the pores are other than NspA pores. Methods for making a thin inorganic membrane with nanopore and sub-nanopore topography and conical cone structure are also disclosed. The thin inorganic membrane may be comprised of any denaturant-resistant materials, such as silicon nitride. A method for manufaacturing the thin inorganic membrane with nanopores is also provided, and provides a thin surface with a defined conical topography, the nanopores being provided on the membrane surface with an electron beam sputinger technique.

description: The authors discuss the current transitions taking place in the Solomon Islands. They argue that while the gradual drawdown of the Regional Assistance Mission to Solomon Islands (RAMSI) is important, it is not the only significant change that is occurring in Solomon Islands and that the short-term policy focus on managing the mission's smooth exit should not obscure what are arguably much larger and more significant transitional challenges facing this small Pacific island country.

The result is expressed within the algebra of 4x4 matrices and is demonstrated to be equivalent to the known limits of isotropic, nonretarded and uniaxial dispersion interactions. The method is also capable of handling dielectric media with smoothly varying anisotropy axes.

title: Comparison of TF-IDF model and BERT model for the classification of articles in an information portal for a case-based recommender system
Creators: name: Jovanovics, Anne Ilona Katharina
Publisher: name: FH Vorarlberg (Fachhochschule Vorarlberg)
Year: 2021
Subjects: subject: 004 Informatik

description: A concept for a recommender system for the information portal swissmom is designed in this work. The challenges posed by the cold start problem and the pregnancy-related temporal interest changes need to be considered in the concept. A state-of-the-art research on recommender systems is conducted to evaluate suitable models for solving both challenges. The explorative data analysis shows that the article's month of pregnancy is an important indicator of how relevant an article is to a user. Neither collaborative filtering, content-based filtering, hybrid models, nor context-aware recommender systems are applicable because the user's pregnancy phase is unknown in the available data. Therefore, the proposed recommender system concept is a case-based model that recommends articles which belong to the same gestation phase as the currently viewed article. This recommender system requires that the month of pregnancy, in which an article is relevant, is known for each article. However, this information is only available for 31% of all articles about pregnancy. Consequently, this work looks for an approach to predict the month of gestation based on the article text. The challenges with this are that only few training data are available, and the article texts of the various months of pregnancy often contain the same terms, considering all articles are about pregnancy. A keyword-based approach using the TF-IDF model is compared with a context-based approach using the BERT model. The results show that the context-based approach outperforms the keyword-based approach.

description: We describe an image analysis supervised learning algorithm that can automatically classify galaxy images. The algorithm is first trained using a manually classified images of elliptical, spiral, and edge-on galaxies. A large set of image features is extracted from each image, and the most informative features are selected using Fisher scores. Test images can then be classified using a simple Weighted Nearest Neighbor rule such that the Fisher scores are used as the feature weights. Experimental results show that galaxy images from Galaxy Zoo can be classified automatically to spiral, elliptical and edge-on galaxies with accuracy of ~90% compared to classifications carried out by the author. Full compilable source code of the algorithm is available for free download, and its general-purpose nature makes it suitable for other uses that involve automatic image analysis of celestial objects.

description: Veresuhkru kõrge taseme puhul on täheldatud kalduvust trombotsüütide agregatsioonile ning trombotsüütide agregatsiooni pärssivad ravimid, kaasa arvatud aspiriin, pole piisavalt tõhusad trombitekke pidurdamisel. Vereglükoosi kõrge tase võib olla üheks aspiriiniresistentsust põhjustavaks teguriks. Töö eesmärk oli uurida tsüklooksügenaasi (COX) inhibiitorite ja L-arginiini toimet trombotsüütide agregatsioonile diabeedihaigetel ja tervetel lühiajalisel glükoosiga inkubeerimisel in vitro. Uuringust selgus, et glükoos pärsib COXi inhibiitorite ja L-arginiini mõju trombotsüütide agregatsioonile. Uuringu tulemused näitavad, et glükoos mõjutab kaht inhibitoorset biokeemilist rada trombotsüüdis: nii COXi kui ka L-arginiini NO-rada.Eesti Arst 2014; 93(5):263–267
