Computerised tomography and magnetic resonance imaging of laryngeal squamous cell carcinoma: A practical approach
2017
Squamous cell carcinoma is the most common head and neck cancer. This review describes the state-of-the-art computerised tomography and magnetic resonance imaging protocols of the neck and the normal larynx anatomy, and provides a practical approach for the diagnosis and staging of laryngeal squamous cell carcinoma.
CO Oxidation on Cationic Gold Clusters: A Theoretical Study
2008
Aiming at understanding the elementary steps governing the oxidation of CO catalyzed by dispersed or supported gold nanoclusters, the reactivity of molecular species, such as O2 and CO, on neutral and positively charged Au13 clusters have been studied using a DFT approach. Two CO oxidation mechanisms have been simulated, involving respectively the adsorption of CO and O2 on adjacent catalytic sites (two-sites mechanism) and the competitive interaction of the reactants on the same site (single-site mechanism). It is demonstrated that in the former scheme a definite interaction of CO and O2 with both the charged and neutral cluster is effective, but that a chemical reaction between the adsorb…
Nozīmes veidošana lietišķajos rakstos
2017
Šajā pētījumā analizēta nozīmes veidošana laikraksta ‘The Economist’ ievadrakstu virsrakstos, apakšvirsrakstos un ievados, kā arī laikraksta ‘The Financial Times’ titulrakstu virsrakstos un apakšvirsrakstos. Pētījuma mērķis bija analizēt nozīmes veidošanu, pētot teikumu un vārdkopu aspektu, situācijas veidu un funkcionālo koherenci. Lai to sasniegtu, tika analizēti 15 laikraksta ‘The Economist’ rakstu virsraksti, apakšvirsraksti un ievadi, kā arī 13 laikraksta ‘The Financial Times’ rakstu virsraksti un apakšvirsraksti. Izmantojot Komrija (1976), Smitas (1991) un Van Dijka (1988) atziņas, pētījumā secināts, ka laikraksta ‘The Economist’ rakstu pirmie elementi ir savstarpēji saistīti ar funkc…
The immunohistochemical expression of leptin in lymph node metastasis from laryngeal squamous cell carcinoma (SCC)
2020
Introduction: Leptin is a proteohormone produced predominantly by white adipocytes and primarily known for its key role in the control of food intake and sense of satiety. From its discover leptin has been found in different body districts, involved in always new functions and processes. In the last years numerous relationships between leptin and cancer has been found. The aim of this study is to test the leptin positivity in human primitive laryngeal squamous cell carcinoma (SCC) and in its lymph node metastasis. Materials and methods: Leptin positivity was detected by immunohistochemical analysis on pathological samples from 18 patients subjected to laryngectomy and neck dissection for SC…
The role of the frequency of constituents in compound words: evidence from Basque and Spanish.
2008
Recent data from compound word processing suggests that compounds are recognized via their constituent lexemes (Juhasz, Starr, Inhoff, & Placke, 2003). The present lexical decision experiment manipulated orthogonally the frequency of the constituents of compound words in two languages: Basque and Spanish. Basque and Spanish diverge widely in their morphological properties and in the number of existing compound words. Furthermore, the head lexeme (i.e., the most meaningful lexeme related to the whole-word meaning) in Spanish tends to be the second lexeme, whereas in Basque the percentage is more distributed. Results showed a facilitative effect of the frequency of the second lexeme, in both …
Vascular labeling of the head and neck vessels : technique, advantages and limitations
2017
Background Vascular staining techniques have been used to describe the vascular structures of several anatomic areas. However, few reports have described this procedure in the head and neck region. This paper describes a head and neck vascular labeling procedure, and describes some of the technical complications that may occur. Material and methods Fifteen specimen cadaver heads were prepared. After drying the vascular system, the internal carotid arteries were ligated and a solution with latex and a gelling agent was injected into the internal carotid arteries and external jugular veins. Two different colors were employed to differentiate arteries from veins. A total of 60ml latex was inje…
Hybrid styles in popular reporting on science :a study of "New Scientist’s" headlines
2014
This project explores some current trends in journalistic textual practices that reflect media outlets’ increased need to engage readers through hybridized forms of coverage. It aims to demonstrate to what extent popular journalism has been assimilated by science communication. It examines a sample of 250 headlines collected over the period of eight months from the list of five “most-read” articles as displayed on the webpage of the international magazine New Scientist. The linguistic, stylistic and rhetorical properties of these headlines are examined quantitatively and qualitatively. The analysis focuses on the ways in which scientific research is popularized through hybrid styles, includ…
Head movements in Finnish Sign Language on the basis of Motion Capture data
2015
This paper reports a study of the forms and functions of head movements produced in the dimension of depth in Finnish Sign Language (FinSL). Specifically, the paper describes and analyzes the phonetic forms and prosodic, grammatical, communicative, and textual functions of nods, head thrusts, nodding, and head pulls occurring in FinSL data consisting of a continuous dialogue recorded with motion capture technology. The analysis yields a novel classification of the kinematic characteristics and functional properties of the four types of head movement. However, it also reveals that there is no perfect correspondence between form and function in the head movements investigated.
Towards a pragma-linguistic framework for the study of sensationalism in news headlines
2013
This article sets out a framework for a language-oriented analysis of sensationalism in news media. Sensationalism is understood here as a discourse strategy of ‘packaging’ information in news headlines in such a way that news items are presented as more interesting, extraordinary and relevant than might be the case. Unlike previous content analyses of sensational coverage, this study demonstrates how sensationalism is instantiated through specific illocutions, semantic macrostructures, narrative formulas, evaluation parameters, and interpersonal and textual devices. Examples are drawn from a corpus of headlines of the ‘most read’ articles in the online outlet of the British mid-market tab…
San Pedro, como era calvo / Saint Peter, as He Was Bald
2018
Resumen. La calvicie de san Pedro que encontramos diversamente reflejada en la tradición popular católica podría muy bien deberse a un episodio referido en la Legenda Aurea (siglo xiii): cuando el apóstol predicaba en Antioquía, sus habitantes, haciendo burla de sus enseñanzas cristianas, le rasuraron la coronilla. Abstract. The fact that Saint Peter is depicted as bald in the Catholic popular tradition is probably due to an episode narrated in the Legenda Aurea (XIIIth century): when St. Peter preached in Antioch, the inhabitants shaved the top of his head in an attempt to mock the Christian law.
