Zobu sakņu rezorbcija: Literatūras un gadījuma apskats
2020
Biežāk netīša gadījuma atradne - saknes rezorbcija (iekšēja vai ārēja) - ir asociēta ar zobu audu, kā arī ar alveolārā kaula lokālu zudumu sakarā ar pastiprinātu osteoklastu funkciju darbību. Visbiežāk asimptomātisku procesu novēro kā patoloģisku procesu patstāvīgā zoba audos vai arī fizioloģisku procesu maiņas sakodienā. Šī gadījuma analīze ietver literatūras apskatu par saknes rezorbcijas etioloģiju, riska un predisponējošiem faktoriem, diagnozes uzstādīšanu un klasifikāciju, kā arī ārstēšanu. Gadījuma analīze: Perforējoša zoba saknes kakliņa daļas rezorbcija.
Forgetting to Remember: The Press Discourse, the Cold War and Conjunctures of Remembrance
2011
The first ‘memory wave’ of the Holocaust, largely based on the depictions of the liberation of the camps and the Nuremberg Trial, was coming to an end in the late 1940s.1 This period, sometimes called the ‘Nuremberg interregnum’,2 was also shaped by discussion relating to the Jewish DPs, the creation of Israel and its aftermath, as this this book has shown. As the Palestine issue became less acute and faded from daily news, talk of the Holocaust also vanished from the public domain. Consequently, the disappearance of the Holocaust from the public eye marked the beginning of a cultural amnesia that lasted, as the dominant historical wisdom now has it, until the 1960s.3 On the other hand, it …
Anesthetic efficacy of Oraqix versus Hurricaine and placebo for pain control during non-surgical periodontal treatment
2014
Objectives: To evaluate the efficacy of Oraqix® during scaling and root planing (SRP) in comparison with 20% benzocaine and placebo. Study Design: 15 patients requiring 4 sessions of SRP were enrolled. For each patient, Oraqix®, Hurricaine®, vaseline or no anesthetic product were randomly assigned each to a quadrant. Treatment pain was evaluated on a 100 mm Visual Analog Scale (VAS) and on a Verbal Rating Scale (VRS). The amount of product administered, the need to re-anesthetise, patient and operator satisfaction and the onset of side-effects were also recorded. Results: Oraqix® was significantly better than nothing, with a reduction of VAS score to 13.3 units, but without significant diff…
Management of dental anxiety via distraction technique
2021
Background The purpose of this study was to evaluate the use of a stress ball as a distraction technique on stress levels of patients undergoing a dental procedure. Material and methods A randomized, split-mouth design was conducted using 20 adult subjects requiring scaling and root planing (Sc/RP) in all four quadrants. Each side of the mouth (maxillary/mandibular) received Sc/RP with local anesthetic with or without the use of a stress-ball distraction over two separate sessions. Subjects completed two pre-procedural questionnaires (Spielberger State-Trait Anxiety Inventory, STAI; Modified Dental Anxiety Scale, MDAS) before and after each treatment session. A Galvanic Skin Response (GSR) …
Quantitative analysis of crystal/grain sizes and their distributions in 2D and 3D
2011
Abstract We review methods to estimate the average crystal (grain) size and the crystal (grain) size distribution in solid rocks. Average grain sizes often provide the base for stress estimates or rheological calculations requiring the quantification of grain sizes in a rock’s microstructure. The primary data for grain size data are either 1D (i.e. line intercept methods), 2D (area analysis) or 3D (e.g., computed tomography, serial sectioning). These data have been used for different data treatments over the years, whereas several studies assume a certain probability function (e.g., logarithm, square root) to calculate statistical parameters as the mean, median, mode or the skewness of a cr…
Crystal Structures and Cytotoxicity of ent-Kaurane-Type Diterpenoids from Two Aspilia Species
2018
A phytochemical investigation of the roots of Aspilia pluriseta led to the isolation of ent-kaurane-type diterpenoids and additional phytochemicals (1⁻23). The structures of the isolated compounds were elucidated based on Nuclear Magnetic Resonance (NMR) spectroscopic and mass spectrometric analyses. The absolute configurations of seven of the ent-kaurane-type diterpenoids (3⁻6, 6b, 7 and 8) were determined by single crystal X-ray diffraction studies. Eleven of the compounds were also isolated from the roots and the aerial parts of Aspilia mossambicensis. The literature NMR assignments for compounds 1 and 5 were revised. In a cytotoxicity assay, 12α-methoxy-ent-kaur-9(11),1…
In vitro evaluation of the temperature increment at the external root surface after Er,Cr:YSGG laser irradiation of the root canal
2009
Objectives. A study was made to determine the temperature increment at the dental root surface following Er,Cr:YSGG laser irradiation of the root canal. Design. Human canines and incisors previously instrumented to K file number ISO 30 were used. Irradiation was carried out with glass fiber endodontic tips measuring 200 µm in diameter and especially designed for insertion in the root canal. The teeth were irradiated at 1 and 2 W for 30 seconds, without water spraying or air, and applying a continuous circular movement (approximately 2 mm/sec.) in the apico-coronal direction. Results. At the 1 W power setting, the mean temperature increment was 3.84ºC versus 5.01ºC at 2 W. In all cases the d…
Fiscal sustainability in EMU countries: A continued fiscal commitment?
2017
Abstract The aim of this paper is to study the sustainability of public finances in the Eurozone particularly after the 2007 financial crisis. This paper goes beyond the standard analysis of the univariate properties of the fiscal variables through the estimation of a time-varying fiscal reaction function on a 11-country panel for a period spanning from 1970 to 2014. Even if panel unit root or stationary tests may provide a rough first insight on the sustainability of the public finances, they fail to highlight the adjustment mechanisms to debt overhang in recent years. The main advantage of our empirical approach is that it clearly captures the government’s dynamic response to debt accumul…
Unemployment dynamics and NAIRU estimates for accession countries: A univariate approach
2005
Abstract In this paper we test for hysteresis effects versus the natural rate hypothesis on unemployment rates of new members in the European Union (EU) using unit root tests that account for the presence of level shifts. In addition, we estimate the non-accelerating inflation rate of unemployment (NAIRU) from a univariate perspective. The precision of these NAIRU are investigated by studying two sources of inaccuracy that derive from the estimation of the break points, and the estimation of the autoregressive parameters. The results indicate up to four structural breaks in the NAIRU of transition countries that can be associated with institutional changes from implementing market-oriented …
The cytotoxic properties of Natural Coumarins Isolated from roots of Ferulago campestris (Apiaceae) and of synthetic ester derivatives aegelinol
2010
Grandivittin (1), agasyllin (2), aegelinol benzoate (3) and felamidin (20), four natural coumarins isolated from Ferulago campestris, and several synthetic ester derivatives of aegelinol (4) were tested against four tumor cell lines. Some of them were shown to be marginally cytotoxic against the A549 lung cancer cell line.
