'I love Rock 'n' Roll'--music genre preference modulates brain responses to music.
2013
The present study examined the effect of participants' music genre preference on the neural processes underlying evaluative and cognitive judgements of music using the event-related potential technique. To this aim, two participant groups differing in their preference for Latin American and Heavy Metal music performed a liking judgement and a genre classification task on a variety of excerpts of either music genre. A late positive potential (LPP) was elicited in all conditions between 600 and 900 ms after stimulus onset. During the genre classification task, an early negativity was elicited by the preferred compared to the non-preferred music at around 230-370 ms whereas the non-preferred g…
Time-Varying mHAP-III Is the Most Accurate Predictor of Survival in Patients with Hepatocellular Carcinoma Undergoing Transarterial Chemoembolization
2021
<b><i>Introduction:</i></b> The prognosis of patients undergoing transarterial chemoembolization (TACE) is extremely variable, and a confounding factor is that TACE is often repeated several times. We retrospectively evaluated the accuracy of different prognostic scores and staging systems in estimating overall survival (OS) in patients with hepatocellular carcinoma (HCC). <b><i>Methods:</i></b> An analysis considering prognostic models as time-varying variables was performed, calculating OS from the time of TACE to the time of the subsequent treatment. Total follow-up time for each patient was therefore split into several observation times ac…

Cannabinoid type 1 receptor modulates intestinal propulsion by an attenuation of intestinal motor responses within the myenteric part of the peristal…
2007
Cannabinoid-1 (CB1) receptor activation affects gastrointestinal propulsion in vivo. It was our aim to further characterize the involved myenteric mechanisms in vivo and in vitro. In CB1(-/-) mice and wild-type littermates we performed in vivo transit experiments by charcoal feeding and in vitro electrophysiological recordings in mouse small intestinal smooth muscle. Ascending neuronal contraction (ANC) following electrical field stimulation was studied in rat ileum in a partitioned organ bath separating the aboral stimulation site from the oral recording site. The knockout animals displayed an accelerated upper gastrointestinal transit compared to control animals. The CB1 receptor antagoni…
Differential effects of CB1 neutral antagonists and inverse agonists on gastrointestinal motility in mice
2010
Background Cannabinoid type 1 (CB1) receptors are involved in the regulation of gastrointestinal (GI) motility and secretion. Our aim was to characterize the roles of the CB1 receptor on GI motility and secretion in vitro and in vivo by using different classes of CB1 receptor antagonists. Methods Immunohistochemistry was used to examine the localization of CB1 receptor in the mouse ileum and colon. Organ bath experiments on mouse ileum and in vivo motility testing comprising upper GI transit, colonic expulsion, and whole gut transit were performed to characterize the effects of the inverse agonist/antagonist AM251 and the neutral antagonist AM4113. As a marker of secretory function we mea…
Mikrozaļumu ķīmiskais sastāvs atkarībā no fotoperioda audzēšanas laikā
2020
Literatūras apskatā ir aprakstīts augu ķīmiskais sastāvs un gaismas ietekme uz to. Apkopotas paraugu sagatavošanas un analīzes metodes. Darbā ir veikta četru dažādu ģiņšu mikrozaļumu diedzēšana pie 4, 8 un 12 stundu ilgiem fotoperiodiem. Spektrometriski ir noteikta kopējā hlorofila un karotenoīdu koncentrācija, kopējā polifenolu koncentrācija un antiradikālā aktivitāte augos. Noteica mikroelementu un makroelementu sastāvu augos ar ICP-MS metodi. Noteica brīvo aminoskābju koncentrāciju augos ar HPLC-MS metodi. Iegūtie dati salīdzināti savā starpā, kā arī tika salīdzināts ķīmiskais sastāvs atkarībā no fotoperioda.

Les compléments neurophysiologiques du diagnostic
2009
Les recherches presentees mettent en evidence des relations entre anomalies comportementales et cognitives et dysfonctionnements cerebraux sous-jacents a partir de methodes d'exploration electrophysiologique non invasives (electroencephalogramme, potentiels evoques auditifs). Trois types de troubles sont etudies : les troubles du sommeil, l'intolerance au changement et l'exploration visuelle atypique des visages humains. La complementarite des approches cliniques et neurophysiologiques est cruciale aux etapes du diagnostic fonctionnel, de l'intervention therapeutique et educative.
Ecología de las currucas mediterráneas en ambientes naturales y agrícolas del este de la península ibérica.
2018
RESUMEN En la presente tesis doctoral se investigan cuatro especies de currucas mediterráneas, la curruca capirotada (Sylvia atricapilla), curruca carrasqueña (S. cantillans), curruca cabecinegra (S. melanocephala) y curruca rabilarga (S. undata); concretamente se estudió su ecología en ambientes naturales y agrícolas del este de la Península Ibérica. En ella se describe la selección y preferencia de hábitat que realizan las especies, así como aspectos de su biología reproductiva. Los objetivos específicos van dirigidos a: 1) determinar la selección de hábitat realizada por las currucas durante su periodo reproductivo, y cómo es dicha selección con la presencia de especies congéneres en eco…
Ab Initio Study on the Mechanism of the Reactions of the Nitrate Radical with Haloalkenes: 1,2-Dichloroethene, 1,1-Dichloroethene, Trichloroethene, …
2000
A general mechanism for the reactions of the NO3 radical with 1,2-dichloroethene, 1,1-dichloroethene, trichloroethene, and tetrachloroethene is proposed from ab initio DFT calculations. The calculated mechanism shows three main parallel reaction pathways. For the systems where the two carbon atoms are differently substituted, the study includes both the attacks with Markownikoff and contra-Markownikoff orientation. The first reaction pathway leads to the formation of an epoxide along with the NO2 radical, the second one to the formation of carbonyl compounds, and the third one leads, through the cleavage of the C−C bond, to the formation of carbonyl compounds with a lower number of carbon a…
