Cell population analysis of the adult murine subependymal neurogenic lineage by flow cytometry
2021
Summary This protocol provides a flow-cytometry-based procedure to classify and isolate all cells of the adult rodent subependymal zone (SEZ) neurogenic lineage, without the need for reporter mice, into different cell populations, including three neural stem cell (NSC) fractions with molecular signatures that are coherent with single-cell transcriptomics. Additionally, their cycling behavior can be assessed by means of 5-ethynyl-2′-deoxyuridine (EdU) incorporation. Our method allows the isolation of different NSC fractions and the functional assay of their cycling heterogeneity and quiescence-activation transitions. For complete details on the use, execution, and outcomes of this protocol, …
High Dimensional Immune Profiling Reveals Different Response Patterns in Active and Latent Tuberculosis Following Stimulation With Mycobacterial Glyc…
2021
Upon infection withMycobacterium tuberculosis(Mtb) the host immune response might clear the bacteria, control its growth leading to latent tuberculosis (LTB), or fail to control its growth resulting in active TB (ATB). There is however no clear understanding of the features underlying a more or less effective response. Mtb glycolipids are abundant in the bacterial cell envelope and modulate the immune response to Mtb, but the patterns of response to glycolipids are still underexplored. To identify the CD45+leukocyte activation landscape induced by Mtb glycolipids in peripheral blood of ATB and LTB, we performed a detailed assessment of the immune response of PBMCs to the Mtb glycolipids lip…
Media devices in pre-school children: the recommendations of the Italian pediatric society
2018
Abstract Background Young children are too often exposed to mobile devices (MD) and most of them had their own device. The adverse effects of a early and prolonged exposure to digital technology on pre-school children has been described by several studies. Aim of the study is to analyze the consequences of MD exposure in pre-school children. Methods We analyzed the documented effects of media exposure on children’s mental and physical health. Results According to recent studies, MD may interfere with learning, children development, well being, sleep, sight, listening, caregiver-child relationship. Discussion Pediatricians should be aware of both the beneficial and side effects of MD and giv…
Nel silenzio di Manet
2017
The absence of instruments and players in the famous “Musique aux Tuileries” (1862) of Édouard Manet, where he represents himself and his own entourage, remains an unsolved problem. On the one hand, the article offers a possible solution of this oddness considering the lack of interest on music in the context of the repertoire. On the other hand, from an aesthetic point of view, the exclusion of musicians from the scene could be explained through the fall of the “aura”. Whatever it may be, the rejection of music marks a separation between the primitive concept of mass music, i.e., the classical repertoire played at the garden of Tuileries, and the future avant-garde.
Mass Communications as a Vehicle to Lure Russian Émigrés Homeward
2011
After the millions of wartime displaced citizens had been forcibly returned to the Soviet Union after the Second World War, the Soviet Union inaugurated a new type of campaign in the mid-1950s to get all the remaining Soviet citizens and former émigrés from Sovietoccupied areas to migrate back. In this campaign, the Soviets used all the means of mass communication they were able to produce, especially radio combined with the press and direct contact with people. The campaign was not very successful, at least not among the people it was supposed to lure back: people residing in Europe. However, many people, especially from Latin America, migrated back to the Soviet Union, only to be disappoi…
Mass appraisal of residential real estate using multilevel modelling
2016
Mass appraisal, or the automatic valuation of a large number of real estate assets, has attracted the attention of many researchers, who have mainly approached this issue employing traditional econometric models such as Ordinary Least Squares (OLS). However, this method does not consider the hierarchical structure of the data and therefore assumes the unrealistic hypothesis of the independence of the individuals in the sample. This paper proposes the use of the Hierarchical Linear Model (HLM) to overcome this limitation. The HLM also gives valuable information on the percentage of the variance error caused by each level in the hierarchical model. In this study HLM was applied to a large dat…
Relationships between mixis in Brachionus plicatilis and preconditioning of culture medium by crowding
1993
Several experiments with Brachionus plicatilis have been conducted to test the existence of chemical-mediated induction of mixis. In a first experimental set, bioassays were used to test relationships between preconditioning of culture medium to high population density and the occurrence of mixis in mass cultures with these media. The results show that a preconditioned medium has inducing properties that are comparable to the crowding effect.
Climate of Opinion as a Driver of Collective Action: Evidence From the 2011 Israeli Social Protest Movement
2018
What drives mass mobilization? A substantial body of theoretical work in diverse fields, including political science, communications, sociology, and economics, is built around the idea that an individual’s willingness to participate in a mobilization is driven by her beliefs about public opinion – that is, about what the majority of the public thinks. Despite the centrality of this idea, rigorous empirical evidence is scarce. We test this idea using original data collected during and after the massive street protests in Israel in the summer of 2011. Our analysis shows that individual beliefs about average societal support for the protest movement (i.e., the “climate of opinion”) are indeed …
The heat of transfer in a chemical reaction at equilibrium.
2007
International audience; We study a reacting mixture (2F $ F2) in a temperature gradient. We had previously used boundary-driven non-equilibrium molecular dynamics (NEMD) simulations to study this system, and found that the reaction was close to local chemical equilibrium in temperature gradients up to 1012 K/m. Using the condition of local chemical equilibrium, we show that the heat of transfer of the reacting mixture is equal to minus the enthalpy of the reaction. The fact that the sign of the heat of transfer is determined by the type of reaction adds insight to the discussion of the origin of the sign
Mix design and mechanical performance of geopolymeric binders and mortars using biomass fly ash and alkaline effluent from paper-pulp industry
2019
Abstract This work investigates the use of biomass fly ash (BFA) and an alkaline effluent (AEF), both generated from the Kraft pulp industry, in the preparation of geopolymeric binders and mortars for construction applications. BFA replaced the metakaolin (MK) while the AEF substituted the distilled water used to dissolve NaOH pellets. The mix design aims to maximize the amount of both the wastes and to optimize the materials properties, such as workability and mechanical performance. At the same time, also the environmental impact decreases enhancing the materials' sustainability and facilitating the circular economy. For the previously optimized BFA/MK ratio (70/30 wt.%) several NaOH/Na2S…
