Inhibitory priming in auditory word recognition: Is it really the product of response biases ?
2007
Les études en amorçage phonologique ont révélé des temps de réponse plus lents lorsque des mots cibles sont précédés d’une amorce partageant avec eux les premiers phonèmes. Cependant, l’interprétation de l’effet d’amorçage inhibiteur est source de controverses. Alors que certains auteurs ont interprété l’effet comme reflétant des processus lexicaux, Pitt et Shoaf (2002) ont émis l’hypothèse que l’effet résulterait d’une surprise des participants lorsqu’ils rencontrent le premier essai relié. Pour éviter un tel biais de réponse, nous avons inclus des amorces et des cibles reliées dans la session d’entraînement, et nous avons comparé comme l’ont fait Pitt et Shoaf, l’amplitude de l’effet sur…
A functional MRI study of happy and sad emotions in music with and without lyrics
2011
Musical emotions, such as happiness and sadness, have been investigated using instrumental music devoid of linguistic content. However, pop and rock, the most common musical genres, utilize lyrics for conveying emotions. Using participants’ self-selected musical excerpts, we studied their behavior and brain responses to elucidate how lyrics interact with musical emotion processing, as reflected by emotion recognition and activation of limbic areas involved in affective experience. We extracted samples from subjects’ selections of sad and happy pieces and sorted them according to the presence of lyrics. Acoustic feature analysis showed that music with lyrics differed from music without lyric…
Der Zerfall des Schriftdeutschen im Estado Novo?
2017
Zusammenfassung Der folgende Beitrag beschäftigt sich mit Sprechern des Hunsrückischen in Brasilien und deren Gebrauch des Schriftdeutschen im 20. Jahrhundert. Basis der Analyse ist ein Korpus von Privatbriefen, die während der ersten Diktatur geschrieben wurden. Der Fokus der Analyse ist die Frage nach einer uniformen Schriftnorm für diese Sprechergruppe, deren Muttersprache fast ausschließlich mündlich verwendet wurde. Es wird argumentiert, dass der Estado Novo nicht die einzige Ursache für den Dachsprachenwechsel vom Deutschen zum Portugiesischen war, jedoch entscheidend dazu beigetragen hat, dass die Etablierung einer brasilianischen Schriftnorm des Deutschen endgültig verhindert wurde.…
Expectation Damages and Bilateral Cooperative Investments
2012
We examine the efficiency of the standard breach remedy expectation damages in a setting where the buyer invests cooperatively and the seller invests both cooperatively and selfishly. Contracts may specify a required quality level and an upper bound to the seller's coordination costs. We find that it is optimal to write an augmented Cadillac contract in which quality is stipulated such that it cannot be met with positive probability together with a very low price. Thus, the seller becomes a residual claimant and the coordination-cost threshold can be used to balance the incentives of the buyer.
Repurposing of the ALK inhibitor crizotinib for acute leukemia and multiple myeloma cells
2021
Crizotinib was a first generation of ALK tyrosine kinase inhibitor approved for the treatment of ALK-positive non-small-cell lung carcinoma (NSCLC) patients. COMPARE and cluster analyses of transcriptomic data of the NCI cell line panel indicated that genes with different cellular functions regulated the sensitivity or resistance of cancer cells to crizotinib. Transcription factor binding motif analyses in gene promoters divulged two transcription factors possibly regulating the expression of these genes, i.e., RXRA and GATA1, which are important for leukemia and erythroid development, respectively. COMPARE analyses also implied that cell lines of various cancer types displayed varying degr…
Treatment choices and neuropsychological symptoms of a large cohort of early MS
2018
ObjectiveTo assess clinical characteristics, distribution of disease-modifying treatments (DMTs), and neuropsychological symptoms in a large cohort of patients with early-stage MS.MethodsThe German National MS Cohort is a multicenter prospective longitudinal cohort study that has recruited DMT-naive patients with clinically isolated syndrome (CIS) and relapsing-remitting MS (RRMS) since 2010. We evaluated their baseline characteristics and the prevalence of neuropsychological symptoms.ResultsOf 1,124 patients, with a 2.2:1 female-to-male ratio and median age at onset of 31.71 years (interquartile range [IQR]: 26.06–40.33), 44.6% and 55.3% had CIS and RRMS, respectively. The median Expanded …
Sunlight exposure exerts immunomodulatory effects to reduce multiple sclerosis severity
2021
AbstractBackgroundMultiple sclerosis (MS) disease risk is associated with reduced sun exposure. This study assessed the relationship between measures of sun-exposure (vitamin D (vitD), latitude) and MS disease severity, the mechanisms of action, and effect-modification by medication and sun-sensitivity associated MC1R variants.MethodsTwo multi-center cohort studies (nNationMS=946, nBIONAT=991). Outcomes were the multiple sclerosis severity score (MSSS) and the number of Gd-enhancing lesion (GELs). RNAseq of four immune cell populations before and after UV-phototherapy of five MS patients.ResultsHigh serum vitD was associated with reduced MSSS (PNationMS=0.021; PBIONAT=0.007) and reduced ris…

Age-related changes in the endocannabinoid system in the mouse hippocampus.
2015
Previous studies have demonstrated that the endocannabinoid system significantly influences the progression of brain ageing, and the hippocampus is one of the brain regions most vulnerable to ageing and neurodegeneration. We have further examined age-related changes in the hippocampal endocannabinoid system by measuring the levels of anandamide (AEA) and 2-arachidonoylglycerol (2-AG) in young and old mice from two different mouse strains. We found a decrease in 2-AG but not AEA levels in aged mice. In order to identify the cause for 2-AG level changes, we investigated the levels of several enzymes that contribute to synthesis and degradation of 2-AG in the hippocampus. We found a selective …
Derivation and validation of a novel bleeding risk score for elderly patients with venous thromboembolism on extended anticoagulation
2017
SummaryExisting clinical scores do not perform well in predicting bleeding in elderly patients with acute venous thromboembolism (VTE). We sought to derive an easy-to-use clinical score to help physicians identify elderly patients with VTE who are at high-risk of bleeding during extended anticoagulation (>3 months). Our derivation sample included 743 patients aged ≥65 years with VTE who were enrolled in a prospective multicenter cohort study. All patients received extended anticoagulation with vitamin K antagonists. We derived our score using competing risk regression, with the time to a first major bleeding up to 36 months of extended anticoagulation as the outcome, and 17 candidate var…
