Zum Akademiestreit als eine Stufe auf dem Weg des Künstlers in sich selbst. Carl Hauptmanns "Einhart der Lächler"
2016
W powieści „Einhart der Lächler“ Carl Hauptmann opisuje drogę życiową artysty, która okazuje się poszukiwaniem własnej tożsamości. Carl Hauptmann ubiera swą opowieść w popularną formę powieści edukacyjnej. Droga Einharta prowadzi przez instytucje sztuki, wówczas napiętnowane przez konflikt pomiędzy wykształceniem akademickim artysty a jego kreatywną wolnością. Poniższy tekst koncentruje się na osadzeniu tego napięcia w ramach historycznych. W dalszej części przedstawione zostaną powiązania głównego bohatera z zaprzyjaźnionym z Carlem Hauptmannem malarzem – Otto Muellerem.
Affective matching of odors and facial expressions in infants: shifting patterns between 3 and 7 months.
2016
Recognition of emotional facial expressions is a crucial skill for adaptive behavior. Past research suggests that at 5 to 7 months of age, infants look longer to an unfamiliar dynamic angry/happy face which emotionally matches a vocal expression. This suggests that they can match stimulations of distinct modalities on their emotional content. In the present study, olfaction-vision matching abilities were assessed across different age groups (3, 5 and 7 months) using dynamic expressive faces (happy vs. disgusted) and distinct hedonic odor contexts (pleasant, unpleasant and control) in a visual-preference paradigm. At all ages the infants were biased toward the disgust faces. This visual bias…
The impact of visual working memory capacity on the filtering efficiency of emotional face distractors.
2018
Emotional faces can serve as distractors for visual working memory (VWM) tasks. An event-related potential called contralateral delay activity (CDA) can measure the filtering efficiency of face distractors. Previous studies have investigated the influence of VWM capacity on filtering efficiency of simple neutral distractors but not of face distractors. We measured the CDA indicative of emotional face filtering during a VWM task related to facial identity. VWM capacity was measured in a separate colour change detection task, and participants were divided to high- and low-capacity groups. The high-capacity group was able to filter out distractors similarly irrespective of its facial emotion. …
Actions différentielles de xéno-hormones alimentaires sur les organes reproducteurs, le foie et le tissu adipeux chez le rat femelle : aspects endocr…
2007
Differential actions of dietary xenohormones on the reproductive organs, the liver and the adipose tissue in the female rat : endocrine, metabolic and morphogenetic aspects regarding the carcinogenic process. Over the past décades, the incidence of hormone-dependent cancers has dramatically increased in Western countries as compared to Asian countries. Environmental and dietary compounds able to mimic and interfère with endogenous hormones, especially reproductive ones, may be involved and among these xenohormones. xenoestrogens (XE) are particularly pointed at. The objective of this thesis was to détermine the conséquences of chronic dietary exposure to phytoestrogens and chemical xenoestr…
La palabra en las maternidades: una aproximación a la psicología perinatal
2001
El reconocimiento del recién nacido como un ser interactuante con el medio físico y humano que lo rodea, implicó cambios en las conductas de los equipos de salud , a cargo de las unidades de internación neonatal. Los conceptos de interacciones precoces, de apego, de díada, de vulnerabilidad maternal, competencias conductuales del recien nacido, y su utilización reciente en el desarrollo de la psicología perinatal, marcaron una transformación en el enfoque de los distintos profesionales involucrados en el proceso del nacimiento. Por un lado, podemos decir que la medicalización del acto del nacimiento en la sociedad occidental ha permitido disminuír el riesgo morbi-mortalidad matern…
Self-assembled Pt2L2 boxes strongly bind G-quadruplex DNA and influence gene expression in cancer cells
2017
Supramolecular Pt(ii) quadrangular boxes bind native and G-quadruplex DNA motifs in a size-dependent fashion. Three Pt molecular squares of distinct size show biological activity against cancer cells and heavily influence the expression of genes known to form G-quadruplexes in their promoter regions. The smallest Pt-box displays less activity but more selectivity for a quadruplex formed in the c-Kit gene.

The title compound, which crystallized as a methanol and water solvate, C24H41NO5·CH4O·H2O, was obtained by heterologous expression of the brasilicardin gene cluster in the bacterium Amycolatopsis japonicum. In the crystal, the components are linked by numerous hydrogen bonds, generating a three-dimensional network.
Performance analysis of Alamouti-coded OFDM systems over spatio-temporally correlated underwater acoustic channels
2017
In this paper, we analyze the performance of Alamouti-coded orthogonal frequency division multiplexing (OFDM) systems over time-varying underwater acoustic (UWA) channels. A realistic UWA channel model has been considered, which can be correlated in either time or space or simultaneously in both domains. An exact analytical expression for the bit error probability (BEP) is necessary to analyze accurately the performance of Alamouti-coded OFDM systems over the spatio-temporally correlated UWA channel model. Hence, by using this UWA channel model, an expression has been derived for the BEP of Alamouti-coded OFDM systems assuming that the receiver knows perfectly the channel state information.…
The transcriptomics of an experimentally evolved plant-virus interaction
2015
[EN] Models of plant-virus interaction assume that the ability of a virus to infect a host genotype depends on the matching between virulence and resistance genes. Recently, we evolved tobacco etch potyvirus (TEV) lineages on different ecotypes of Arabidopsis thaliana, and found that some ecotypes selected for specialist viruses whereas others selected for generalists. Here we sought to evaluate the transcriptomic basis of such relationships. We have characterized the transcriptomic responses of five ecotypes infected with the ancestral and evolved viruses. Genes and functional categories differentially expressed by plants infected with local TEV isolates were identified, showing heterogene…
PGDH family genes differentially affect Arabidopsis tolerance to salt stress
2019
The first step in the Phosphorylated Pathway of serine (Ser) Biosynthesis (PPSB) is catalyzed by the enzyme Phosphoglycerate Dehydrogenase (PGDH), coded in Arabidopsis thaliana by three genes. Gene expression analysis indicated that PGDH1 and PGDH2 were induced, while PGDH3 was repressed, by salt-stress. Accordingly, PGDH3 overexpressing plants (Oex PGDH3) were more sensitive to salinity than wild type plants (WT), while plants overexpressing PGDH1 (Oex PGDH1) performed better than WT under salinity conditions. Oex PGDH1 lines displayed lower levels of the salt-stress markers proline and raffinose in roots than WT under salt-stress conditions. Besides, the ratio of oxidized glutathione (GSS…
