Ethanol promotes survival and tumor progression of colon cancer cells

2018

In the Western Countries, colon cancer is the third tumor for aggressiveness and incidence after lung and breast/prostate cancer. Different risk factors concur to the development of colon cancer, including genetic factors, inflammation, intestinal microflora composition, as well as lifestyle. Epidemiologic studies correlating alcohol consumption and assert that the risks are 5-fold higher among drinkers compared to nondrinkers. However, the exact mechanisms correlating heavy alcohol drinking and colon cancer are not completely elucidated yet. To shed light on the biochemical mechanisms through which alcohol favors colon cancer progression, we evaluated the effect of high doses of ethanol (1…

Growth and biomass partitioning of Arbutus unedo, Laurus nobilis, Phillyrea angustifolia and Rhamnus alaternus seedlings under water deficit

2013

Water scarcity in the Mediterranean areas is very common and the selection of drought tolerant species is a priority for landscaping purposes in the Mediterranean areas. The objective of this study was to evaluate the effect of water deficit on growth and biomass partitioning of Arbutus unedo, Laurus nobilis, Phillyrea angustifolia and Rhamnus alaternus. Seventy-two seedlings per species were grown in the greenhouse in 4-liter pots and three water regimes were imposed starting on 6 April and until 9 June, 2010. One-third of the plants was well irrigated to maintain soil water content in the 25-35% range (CTR); a second group of plants was deficit-irrigated to maintain soil water content in …

Upscaling leaf gas exchange measurements to the whole grapevine canopy: An update

2009

This review first revisits current knowledge about single-leaf function, viz. photosynthesis, chiefly in relation to environmental factors, that underscores the importance of multiple summer stresses. Emphasis is placed on the response different genotypes show under light and heat stress with or without soil-water shortage. Secondly, it tackles the thorny issue of extrapolating single-leaf readings to the whole-canopy level, with special reference to both methodological and physiological implications. Whole-canopy gas-exchange systems deliver and emphasise the usefulness of such an approach in achieving key research goals. One case in point is quantifying the amount and dynamics of canopy g…

Activating Character Strengths Through Poetic Encounters in a Foreign Language - A Case Study

2016

The paper brings together two important issues related to effective functioning of foreign/second language learners, that is character strengths (one of the pillars of positive psychology) and the use of literary texts for language learning. The goals of using literary texts in a foreign/second language learning contexts and the goals of positive psychology converge. Both literature and positive psychology aim at enriching and expanding individual and social functioning and so they contribute to satisfaction and flourishing. The case study reported in the paper aimed at finding the participants’ opinions about the role of literary texts in foreign language learning and checking whether work…

Mechanical Behavior of Concrete Columns Confined by Laterally Pre-Tensioned FRP

2011

This paper presents the results of an experimental investigation of concrete columns confined by a wound pre-tensioned carbon filament yarn. Yarn winding equipment was developed in the Institute of Polymer Mechanics with the ability to set the desired pre-tension force and thereby producing confined concrete specimens with different initial lateral pressure. It is shown that initial lateral pressure increases the axial stress at which intense internal cracking of the concrete develops.

Hidden biochemical action of Ethanol on colon carcinoma cell models

Colorectal cancer (CRC) is one of the most widespread cancers in the world. Numerous risk factors have been correlated with the development of CRC, including genetic factors, inflammation, intestinal microflora composition, as well as lifestyle factors, such as smoking, high consumption of red meats and alcohol intake. Epidemiological studies support the conclusion that chronic and heavy alcohol consumption increases the risk to develop CRC as well as favors the progression of this form of cancer. However, the biochemical mechanisms responsible for these events have not yet been fully clarified. The aim of my doctoral project was to study the effects of ethanol in human colorectal carcinoma…

The novice language teacher's guide to survival : dialogue between the new and the experienced language teacher

2017

Aloittelevat opettajat kohtaavat ammatissaan merkittävän määrän haasteita ensimmäisien työvuosien aikana (Blomberg 2009; Heikkinen et al. 2012; Laaksola 2007). Haasteita ovat muun muassa psykologiset aspektit kuten identiteetin muodostaminen ja stressi (Kyriacou 2001; Niemi 1998), sekä ulkoiset tekijät kuten opettajiin kohdistuvat ristiriitaiset odotukset ja alati muuttuva työympäristö (Luukkainen 2005; Niemi 1999). Idea tarjota tukea aloittelevalle opettajalle syntyi kirjoittajien omista kokemuksista ja keskusteluista koskien aloittelevan opettajan asemaa. Monia kollegojamme huolestutti opetusharjoittelujakson pituus, ja moni tuleva aineenopettaja koki, ettei ollut valmis kohtaamaan kielen…

Two-neutrino ββ decays and low-lying Gamow-Teller β− strength functions in the mass range A=70–176

2017

We apply the proton-neutron deformed quasiparticle random-phase approximation (pn-dQRPA) to describe the low-lying (E 6 MeV) 1+ Gamow-Teller (GT) strength functions in odd-odd deformed nuclei which participate as intermediate nuclei in two-neutrino double-β-decay (2νββ) transitions within the mass range A = 70–176. In deriving equations of motion we use a single-particle basis with projected angular momentum, provided by the diagonalization of a spherical mean field furnished with a quadrupole-quadrupole interaction. The schematic residual Hamiltonian contains pairing and proton-neutron interaction terms in particle-hole (ph) and particle-particle (pp) channels, with constant strengths. By …

Teachers’ Focus of Attention in First-grade Classrooms: Exploring Teachers Experiencing Less and More Stress Using Mobile Eye-tracking

2021

This study investigated teachers’ focus of attention and stress in first-grade classrooms. Teachers’ (n = 53) focus of attention was recorded in fall and spring with a mobile eye-tracking device, and the teachers reported stress via questionnaires. Correlation analysis was used to examine association between teacher stress (exhaustion, cynicism, and inadequacy) and focus of attention. Then, one teacher reporting more stress and one reporting less stress were selected for a case study to examine variations in their focus of attention. The results showed positive associations between teachers’ perceived inadequacy and overall focus of attention (whole eye-tracking recording) both in fall and …

β Decay of 127Cd and Excited States in 127In

2019

A dedicated spectroscopic study of the β decay of 127Cd was conducted at the IGISOL facility at the University of Jyväskylä. Following high-resolution mass separation in a Penning trap, β−γ−γcoincidences were used to considerably extend the decay scheme of 127In. The β-decaying 3/2+ and 11/2− states in 127Cd have been identified with the 127Cd ground state and the 283-keV isomer. Their respective half-lives have been measured to 0.45(128)s and 0.36(4) s. The experimentally observed βfeeding to excited states of 127In and the decay scheme of 127In are discussed in conjunction with large-scale shell-model calculations. peerReviewed
