Occurrence of Mycotoxins in Botanical Dietary Supplement Infusion Beverages.

2019

The aim of the present work was to study the occurrence of mycotoxins [aflatoxins (1-4), 3-acetyldeoxyniavlenol (5), 15-acetyldeoxynivalenol (6), nivalenol (7), HT-2 (8), T-2 (9), ochratoxin A (10), zearalenone (11), enniatin A (12), enniatin A1 (13), enniatin B (14), enniatin B1 (15), and beauvericin (16)] present in potable products derived from herbal teas. Analysis was carried out by liquid chromatography coupled to ion-trap tandem mass spectrometry (LC-MS/MS-IT) after a dispersive liquid-liquid microextraction procedure (DLLME) was conducted. The DLLME method was applied to 52 commercial samples of chamomile, chamomile with anise, chamomile with honey, linden, pennyroyal mint, thyme, v…

Reliģiskais simbolisms Luīzes Erdrikas romānos

2018

Šī pētījuma autors analizē, kādā veidā tiek izmantoti reliģiskie simboli Luīzes Erdrikas tetraloģijā, kas sastāv no romāniem “Mīlas Medicīna”, “Pēdas”, “Biešu Karaliene” un “Bingo Pils”. Reliģisko simbolismu analizēšana viņas romānos ļaus saprast Amerikas indiāņu sarežģīto identitātes veidošanās procesu Amerikas kolonizācijas apstākļos. Pētījuma mērķis ir analizēt, kādos veidos Erdrika izmanto reliģisko simbolismu minētajā tetraloģijā. Pētījuma metodes ir padziļinātā lasīšana, stāstījuma analīze un salīdzinošā interpretatīvā metode, balstoties uz postkoloniālās, Amerikas Indiāņu, stāstījuma analīzes un kulturvēsturiskā diskursa analīzes metodoloģijām. Šajā pētījumā izmantotās metodoloģijas …

Smertekartlegging og smertelindring hos pasienter med demens: Utfordringer og dilemmaer

2013

Published version of an article in the journal: Vård i Norden. Also available from the publisher at: http://www.artikel.nu/Public/Main.aspx Aim: to explore nurses' experiences with pain assessment and pain relieving in patient with dementia. Background: research shows that patients with dementia are still suffering from unnecessary pain. The reason it may be nurses difficulty to interpret and map patients’ pain. Method: data were collected through three different focus group interviews. A semi – structured interview guide was developed to answer the research question. Data were analyzed by using a content analysis in four steps. Findings: The findings are divided into three sub – categories…

Vitamin D in cancer chemoprevention

2015

Context: There is increasing evidence that Vitamin D (Vit D) and its metabolites, besides their well-known calcium-related functions, may also exert antiproliferative, pro-differentiating, and immune modulatory effects on tumor cells in vitro and may also delay tumor growth in vivo. Objective: The aim of this review is to provide fresh insight into the most recent advances on the role of Vit D and its analogues as chemopreventive drugs in cancer therapy. Methods: A systematic review of experimental and clinical studies on Vit D and cancer was undertaken by using the major electronic health database including ISI Web of Science, Medline, PubMed, Scopus and Google Scholar. Results and conclus…

Personalized cancer medicine: from molecular diagnostics to targeted therapy with natural products.

2010

Personalized cancer medicine aims to develop individualized treatment options adapted to factors relevant for the prognosis of each patient. Molecular biomarkers are required to predict the likelihood of an individual tumor's responsiveness or of toxicity in normal organs and to advise optimized treatments with improved efficacy at reduced side effects for each cancer patient. In the present review, we present a concept, which takes advantage of methods of molecular diagnostics to identify predictive markers at the DNA, mRNA, and protein levels. Markers with prognostic value concerning treatment response and patient survival can then be used as targets to develop optimized drugs. We focus o…

Synchronicity matters: defining the characteristics of digital generations

2015

This paper investigates whether or not the proposition that the second digital generation (or so-called digital natives) is more engaged in social use of the Internet than older generations is tenable. By analysing nationally representative questionnaire-based survey data collected from Finland in 2011 (N = 612), the study shows that rather than social use of the Internet in general, it is the synchronicity of online communication that distinguishes user generations. Results show that, in contrast to asynchronous modes of online communication (e.g. social networking sites, blogs and online discussion forums), synchronous modes (e.g. instant messaging and Internet calls) are clearly generati…

Paper vs. Pixel: Can We Use a Pen-and-Paper Method to Measure Athletes' Implicit Doping Attitude?

2017

Doping attitude is an individual’s subjective evaluation (e.g., good or bad, useful or useless) toward the use of prohibited performance-enhancing substances or methods in sports. Research on doping attitude has traditionally relied on self-report questionnaire methods to measure the construct (Ntoumanis et al., 2014; Chan et al., 2015). However, as doping in sport is illegal (World AntiDoping Agency, 2015) and perceived as socially unacceptable, athletes who hold positive attitudes toward doping are less likely to reveal them to others. As a result explicit measures of doping attitude are susceptible to potential bias as athletes may respond in a socially desirable fashion (Petróczi and Ai…

Opportunity costs and efficiency of investments in mega sport events

2009

Economic analyses of mega sport events usually focus on the positive effects and legacies while ignoring opportunity costs and the efficiency of using scarce resources. Event opponents argue that decisions to invest public resources should also consider alternative uses of the money. This paper aims to clarify some of the issues surrounding the opportunity costs of mega sport events. By using the measure ‘efficiency’ (output/input) of alternative investments it will become clear that the decision to stage a mega sport event cannot be taken in isolation and that there are many factors that need to be considered. The argument put forward is based on a stakeholder’s perspective and a spatial d…

El viaje desde los cuestionarios Likert a los cuestionarios de elección forzosa: evidencia de la invarianza de los parámetros de los ítems

2019

Multidimensional forced-choice questionnaires are widely regarded in the personnel selection literature for their ability to control response biases. Recently developed IRT models usually rely on the assumption that item parameters remain invariant when they are paired in forced-choice blocks, without giving it much consideration. This study aims to test this assumption empirically on the MUPP-2PL model, comparing the parameter estimates of the forced-choice format to their graded-scale equivalent on a Big Five personality instrument. The assumption was found to hold reasonably well, especially for the discrimination parameters. In the cases in which it was violated, we briefly discuss the …
