Measuring music-induced emotion: A comparison of emotion models, personality biases, and intensity of experiences
2011
Most previous studies investigating music-induced emotions have applied emotion models developed in other fields to the domain of music. The aim of this study was to compare the applicability of music-specific and general emotion models – namely the Geneva Emotional Music Scale (GEMS), and the discrete and dimensional emotion models – in the assessment of music-induced emotions. A related aim was to explore the role of individual difference variables (such as personality and mood) in music-induced emotions, and to discover whether some emotion models reflect these individual differences more strongly than others. One hundred and forty-eight participants listened to 16 film music excerpts a…
Style partycypacji kulturalnej człowieka dorosłego. Walidacja narzędzia pomiarowego
2018
The article presents a measurement tool validation process diagnosing an adult person’s cultural participation styles. Its objective is to describe the obtained results at individual stages of the validation and determine the connection between cultural participation styles and cultural systems presented by sociologists of culture. Consequently, cultural participation style of an adult person is the subject of the research. The pilot studies as well as the actual research have been conducted in Opolskie province. The research sample amounted to 100 respondents, then 400 respondents, respectively. The theoretical construct of Kazimierz Obuchowski describing the objective and subjective stand…
Relative expression of cholesterol transport-related proteins and inflammation markers through the induction of 7-ketosterol-mediated stress in Caco-…
2013
Human diets contain sterol oxidation products that can induce cytotoxic effects, mainly caused by cholesterol oxides. However, phytosterol oxides effects have been less extensively investigated. This study evaluates the production of inflammatory biomarkers (IL-1β, IL-8, IL-10, TNFα) and the influence of gene expression transporters and enzymes related to cholesterol absorption and metabolism (NPC1L1, ABCG5/8, HMGCoA, ACAT) produced by 7-ketosterols (stigmasterol/cholesterol) in Caco-2 cells. These effects were linked to intracellular signaling pathways by using several inhibitors. Results showed 7-ketostigmasterol to have a greater proinflammatory potential than 7-ketocholesterol. In non-p…
Low cholesterol stimulates the nonamyloidogenic pathway by its effect on the α-secretase ADAM 10
2001
Biochemical, epidemiological, and genetic findings demonstrate a link between cholesterol levels, processing of the amyloid precursor protein (APP), and Alzheimer's disease. In the present report, we identify the α-secretase ADAM 10 ( a d isintegrin a nd m etalloprotease) as a major target of the cholesterol effects on APP metabolism. Treatment of various peripheral and neural cell lines with either the cholesterol-extracting agent methyl-β-cyclodextrin or the hydroxymethyl glutaryl-CoA reductase inhibitor lovastatin resulted in a drastic increase of secreted α-secretase cleaved soluble APP. This strong stimulatory effect was in the range obtained with phorbol esters and was further increa…
Addiction-Like Mobile Phone Behavior – Validation and Association With Problem Gambling
2018
Mobile phone use and its potential addiction has become a point of interest within the research community. The aim of the study was to translate and validate the Test of Mobile Dependence (TMD), and to investigate if there are any associations between mobile phone use and problem gambling. This was a cross-sectional study on a Swedish general population. A questionnaire consisting of a translated version of the TMD, three problem gambling questions (NODS-CLiP) together with two questions concerning previous addiction treatment was published online. Exploratory factor analysis based on polychoric correlations was performed on the TMD. Independent samples T-tests, Mann-Whitney test, logistic …
Argumentativeness among Selected Finnish and American College Students
1991
Summary.-Compared on the Infante/Rancer Argumentativeness scale, 247 Finnish university students had a significantly higher mean score on argumentativeness as a trait than 155 American university students. No significant difference was noted on the desire to approach arguments, but the American students were significantly more inclined to avoid arguments than the Finnish students. Conceptualized by Infante and Rancer (1982) as a personality trait, argumentativeness contains tendencies to approach and to avoid arguments. Persons with approach tendencies will advocate issues on controversial positions and attack conflicting positions. Those with avoidance tendencies try to stay out of argumen…
Granulocyte Activity Is Enhanced by Culture Supernatants of Mononuclear Leukocytes Incubated with Tetrachlorodecaoxide
1995
Granulocytes (polymorphonuclear leukocytes, PMNs) and monocytes/ macrophages are important in wound healing. Within the first few hours PMNs and monocytes begin to infiltrate sites of injury. The major function of PMNs is to kill microbes and phagocytose cellular debris so that healing can proceed [1]. Monocytes/macrophages invading the wound are also active in phagocytosis. In addition they release a number of cytokines including growth factors, interleukin-8 (IL-8), and tumor necrosis factor (TNF-α) needed for new tissue formation and shown to stimulate PMNs [1–3].
Alpha-Synchronized Stimulation of the Dorsolateral Prefrontal Cortex (DLPFC) in Major Depression: A Proof-of-Principle EEG-TMS Study
2018
High-frequency repetitive transcranial magnetic stimulation (rTMS) of the left dorsolateral prefrontal cortex (DLPFC) shows therapeutic potential in pharmaco-resistant patients with major depression. However, clinical efficacy is limited by high inter-individual variability and low response rates. One possible strategy to improve the effect size and consistency may be brain state dependent brain stimulation, i.e. coupling of TMS pulses to the endogenous brain states as reflected by the instantaneous oscillatory brain activity. Here we present findings from a proof-of-principle study of alpha-oscillation synchronized brain stimulation of the frontal cortex in patients with major depression (…

Squaric Acid-Based Radiopharmaceuticals for Tumor Imaging and Therapy.
2021
Targeting vectors bound to a chelator represent a significant fraction of radiopharmaceuticals used nowadays for diagnostic and therapeutic purposes in nuclear medicine. The use of squaramides as coupling units for chelator and targeting vector helps to circumvent the disadvantages of several common coupling methods. This review gives an overview of the use of squaric acid diesters (SADE) as linking agents. It focuses on the conjugation of cyclic chelators, e.g., DOTA (1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid), as well as hybrid chelators like AAZTA5 (6-pentanoic acid-6-amino-1,4-diazepine tetracetic acid) or DATA5m (6-pentanoic acid-6-amino-1,4-diazapine-triacetate) to diff…
