Ethanol intake in male mice exposed to social defeat: Environmental enrichment potentiates resilience
2021
Large preclinical evidence shows that exposure to social defeat (SD) increases vulnerability to drug abuse, increasing the consumption of ethanol. However, not all subjects are equally affected by the changes induced by stress. Previous reports have evidenced that the resilient phenotype to depressive-like behaviors after SD is associated with the resistant phenotype to cocaine-increased rewarding effects and the smaller neuroinflammatory response. The aim of the present study was to further clarify whether the resilient profile to depressive-like behavior also predicts a protection against the increase in ethanol intake induced by SD. The neuroinflammatory profile was studied after the end…
Work satisfaction, psychological resiliency and sense of coherence as correlates of work engagement
2018
The objective of the article is to describe the links between work engagement—the response variable, work satisfaction—the explanatory variable, and sense of coherence, along with resiliency as resources—moderating variables. The theoretical foundations for our hypotheses are Hackman and Oldham’s Job Charcteristics Model, Block and Kremen’s conception of resiliency, Antonovsky’s salutogenesis, the JD-R of relation between work demands and resources and also the model of work engagement in the research of Schaufeli, Salanova, González-romá, and Bakker. Methods: 94 independent workers of Polish branches of international corporations were studied. Work satisfaction was measured using the SSP s…
Spectroscopy of 253No and its daughters
2011
Abstract New high-statistics data have been obtained on the decay properties of 253 No and its daughters using the reaction 207 Pb( 48 Ca, 2n) 253 No. This was made possible thanks to an improved transmission of fusion–evaporation residues through the VASSILISSA recoil separator and an increased efficiency of the GABRIELA detector setup. The decay schemes of 253 No and 249 Fm have been revisited. The known level scheme of 249 Fm has been confirmed, including a new level at 669 keV excitation energy. The observation of L X-rays in coincidence with the α decay of 249 Fm gives additional support to the ground-state configuration of 1 / 2 + [ 631 ] instead of 5 / 2 + [ 622 ] for 245 Cf. In both…
Total Nut, Tree Nut, and Peanut Consumption and Metabolic Status in Southern Italian Adults.
2021
Background: Nut consumption has been associated with cardio-metabolic health benefits. However, studies conducted in the Southern Italian population, where adherence to the Mediterranean diet has been reported being relatively high, are rather scarce. The aim of this study was to test the association between consumption of total and specific types of nuts and metabolic status among adults living in Sicily, Southern Italy. Methods: Demographic and dietary characteristics of 2044 adults living in Southern Italy were analyzed. Multivariate logistic regression analyses were performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs) of the association between nut consumption and…

Miksi työmarkkinoiden ja kielikoulutuksen tarpeet eivät kohtaa?
2012
Luopumalla eri kielten lokeroajattelusta ja omaksumalla uudenlainen näkemys kielten opiskeluun tuotettaisiin suurempaa kielitaitohyötyä niin työelämässä kuin sen ulkopuolellakin. Language for Jobs työryhmä on etsinyt ratkaisuja kielitaitotarpeiden ja kielikoulutuksen tarjonnan kohtaamisen ongelmiin.
Suomalainen korkeakoulutus kriisissä?
2005
”Voi liioittelematta sanoa, että kaikki suomalaiset yliopistot kuuluvat ’maailmanluokan’ yliopistoihin. Mistä siis nousee Jorma Rantasen ja Anne Brunilan raporteissa esitetty ehdotus luoda Suomeen muutama ’maailmanluokan’ yliopisto, joiden ohella olisi kansallisen tai maakunnallisen tason opinahjoja? Kysymys näyttäisi olevan koulutuspolitiikan suunnan muutosyrityksistä kohti markkinatalouden kilpailuun perustuvaa arvomaailmaa”, kirjoittaa professori Jussi Välimaa.
Upstream Product Market Regulations, ICT, R&D and Productivity
2017
Our study aims to assess the actual importance of the two main channels via which upstream anti-competitive sector regulations are usually considered to impact productivity growth, i.e. by acting as a disincentive to business investments in R&D and in ICT. We estimate the specific impacts of these two channels and their shares in the total impact as opposed to alternative channels of investments in other forms of intangible capital that we cannot explicitly consider for lack of appropriate data such as improvements in skills, management and organization. To achieve this, we specify an extended production function explicitly relating productivity to R&D and ICT capital as well as to upstream…
Projections from the posterolateral olfactory amygdala to the ventral striatum: neural basis for reinforcing properties of chemical stimuli
2007
Abstract Background Vertebrates sense chemical stimuli through the olfactory receptor neurons whose axons project to the main olfactory bulb. The main projections of the olfactory bulb are directed to the olfactory cortex and olfactory amygdala (the anterior and posterolateral cortical amygdalae). The posterolateral cortical amygdaloid nucleus mainly projects to other amygdaloid nuclei; other seemingly minor outputs are directed to the ventral striatum, in particular to the olfactory tubercle and the islands of Calleja. Results Although the olfactory projections have been previously described in the literature, injection of dextran-amines into the rat main olfactory bulb was performed with …
Comparison of the combined action of oxaliplatin or cisplatin and radiation in cervical and lung cancer cells
2007
To test the combined effects of oxaliplatin and radiation versus cisplatin and radiation using human cervical and lung cancer cell lines.CaSki cervical cancer cells, and A549 lung cancer cells were cultured under standard conditions. Cells were treated with escalating doses of gamma-irradiation (0-6 Gy), and with oxali- and cisplatin for 2 h or 24 h, or a combination of both. Cell survival was measured by a colony-forming assay. Survival curves were fitted to the data using the linear quadratic model. Sensitizer enhancement ratios (SER) were calculated at the 37% survival level, and isobologram analysis was applied to test for the drug-radiation interactions.Oxaliplatin as well as cisplatin…
