317 Role of integrins in the metastatic spread of high-grade serous ovarian cancer
2021
Introduction/Background* In high-grade serous ovarian cancer (HGSOC) an early intraperitoneal metastatic spread is common which determines the therapeutical approach and prognosis. Integrins may be involved in metastatic spread of HGSOC. In this study, integrin expression was examined in primary tumour and metastases of HGSOC. Methodology The expression of integrin α2, α4, α5, α6, and β1 was assessed by immunostaining in tumour samples of the ovary, omentum, and peritoneum of each patient. Differences in integrin expression among tumour localisations and their association with clinicopathological parameters were examined by Fisher’s exact test. The impact of integrin expression on progressi…
Details from the Life of the Bonhoeffer Family: New Insights about the Biography and Theology of Dietrich Bonhoeffer in the Memoirs of his Youngest S…
2020
Just recently, the autobiography of Susanne Bonhoeffer, the younger sister of Dietrich Bonhoeffer, has been rediscovered. She has bequeathed an excellent and extensive description of her family’s life and reveals new insights about the Bonhoeffer family and the history of her time. Her work will be a substantial contribution to further research. As the editor of this challenging project, I would like to investigate how this text may affect our perception of Dietrich Bonhoeffer’s biography and theology. A lot of information about Dietrich Bonhoeffer is offered in the autobiography of his sister Susanne – last but not least about his time in prison, when Susanne was sent by her family to vis…

Speed-accuracy trade-off and its consequences in a scramble competition context.
2014
Abstract: Animals foraging in groups commonly respond to the presence of others by increasing their foraging rate, an increase that could come at the expense of prey detection accuracy. Yet the existence and consequences of such so-called 'speed-accuracy trade-offs' in group-foraging animals remain unexplored. We used group-feeding zebra finches, Taeniopygia guttata, to determine how search speed affects food detection accuracy and how a potential speed-accuracy trade-off influences feeding success. We found significant between-individual differences in hopping speed as well as evidence that faster individuals were more likely to overlook food, demonstrating the existence of a trade-off bet…
Analytical comparison and sensory representativity of SAFE, SPME, and Purge and Trap extracts of volatile compounds from pea flour
2012
Pisum sativum is of great economic and nutritional interest due to its protein content. Nevertheless, pea products are underused as a protein source in human food because of their strong beany flavour. Therefore, the objective of this study was to select an efficient and representative method to extract volatile molecules of pea flour. In the first step, three extraction methods were chosen: solid phase micro extraction (SPME); Purge and Trap extraction and solvent assisted flavour evaporation (SAFE). The corresponding extracts were analysed by gas chromatography coupled with mass spectrometry. In the second step, the sensory representativity of the extracts was assessed either by direct ga…
Seasonal fluctuations and long-term persistence of pathogenic populations of Agrobacterium spp. in soils.
2002
ABSTRACT Short- and long-term persistence of pathogenic (i.e., tumor forming) agrobacteria in soil was investigated in six nursery plots with a history of high crown gall incidence. No pathogenic Agrobacterium strains were isolated in soil samples taken in fall and winter in any plots, but such strains were isolated from both bulk soils and weed rhizospheres (over 0.5 × 10 5 pathogenic CFU/g of bulk soil or rhizosphere) in three out of six plots in spring and summer. PCR amplifications of a vir sequence from DNA extracted from soil confirmed the presence of Ti plasmids in summer and their absence in fall and winter. The results indicate that strains that harbor a Ti plasmid had an unforesee…
Research Regarding the Use of Wheat Biodiversity for Obtaining some Cereal-Based Fermented Mashes
2012
International audience; Cereal-based fermented beverages are an opportunity to include probiotics and fiber in human nutrition. Nowadays, increasing the interest for rediscovering the benefits, on scientific basis, of traditional fermented beverages based on cereals. Fermented mashes based on different cereal grist, namely Braga in Romanian, is a healthy and nutritious beverage, a source for new functional products with beneficial effects on human health. Physical-chemical and sensorial characteristics of these beverages depend on the ingredients and method of preparation. In this article was analyzed the influence of the five varieties of wheat on the main physical-chemical and sensorial c…
Expression Patterns of Key Hormones Related to Pea (Pisum sativum L.) Embryo Physiological Maturity Shift in Response to Accelerated Growth Conditions
2019
Protocols have been proposed for rapid generation turnover of temperate legumes under conditions optimized for day-length, temperature, and light spectra. These conditions act to compress time to flowering and seed development across genotypes. In pea, we have previously demonstrated that embryos do not efficiently germinate without exogenous hormones until physiological maturity is reached at 18 days after pollination (DAP). Sugar metabolism and moisture content have been implicated in the modulation of embryo maturity. However, the role of hormones in regulating seed development is poorly described in legumes. To address this gap, we characterized hormonal profiles (IAA, chlorinated auxin…
Systèmes imageurs 3D pour des applications agricoles : caractérisation de cultures et phénotypage de racines
2016
The development of the concepts of precision agriculture and viticulture since the last three decades has shown the need to use first 2D image acquisition techniques and dedicated image processing. More and more needs concern now 3D images and information. The main ideas of this chapter is thus to present some innovations of the 3D tools and methods in the agronomic domain. This chapter will particularly focus on two main subjects such as the 3D characterization of crop using Shape from Focus or Structure from Motion techniques and the 3D use for root phenotyping using rhizotron system. Results presented show that 3D information allows to better characterize crucial crop morphometric parame…
