A global DNA repair mechanism involving the Cockayne syndrome B (CSB) gene product can prevent the in vivo accumulation of endogenous oxidative DNA b…
2002
The Cockayne syndrome B (CSB) gene product is involved in the repair of various types of base modifications in actively transcribed DNA sequences. To investigate its significance for the repair of endogenous oxidative DNA damage, homozygous csb(-/-)/ogg1(-/-) double knockout mice were generated. These combine the deficiency of CSB with that of OGG1, a gene coding for the mammalian repair glycosylase that initiates the base excision repair of 7,8-dihydro-8-oxoguanine (8-oxoG). Compared to ogg1(-/-) mice, csb(-/-)/ogg1(-/-) mice were found to accumulate with age severalfold higher levels of oxidited purine modifications in hepatocytes, splenocytes and kidney cells. In contrast, the basal (ste…
Patient-specific computational evaluation of stiffness distribution in ascending thoracic aortic aneurysm
2021
Quantifying local aortic stiffness properties in vivo is acknowledged as essential to assess the severity of an ascending thoracic aortic aneurysm (ATAA). Recently, the LESI (local extensional stiffness identification) methodology has been established to quantify non-invasively local stiffness properties of ATAAs using electrocardiographic-gated computed tomography (ECG-gated CT) scans. The aim of the current study was to determine the most sensitive markers of local ATAA stiffness estimation with the hypothesis that direct measures of local ATAA stiffness could better detect the high-risk patients. A cohort of 30 patients (12 BAV and 18 TAV) referred for aortic size evaluation by ECG-gated…
Musiikin kuuntelu itsehoidollisena menetelmänä stressin lievityksessä
2016
Tämän tutkielman tarkoituksena oli tarkastella musiikin kuuntelua stressin lievityksessä arkipäivässä. Musiikin kuuntelun on todettu lievittävän stressiä tehokkaasti mutta aiemmat tutkimukset aiheesta ovat olleet lähinnä määrällisiä. Tässä tutkimuksessa aihetta lähestyttiin laadullisin menetelmin, jossa pyrittiin stressin lievityksen osalta kartoittamaan musiikillisten piirteiden lisäksi myös ihmisten kokemuksia aiheesta. Tutkimus toteutettiin haastattelemalla neljää henkilöä, jotka kuuntelivat musiikkia arkipäivässään stressin lievitykseen. Haastatteluaineisto analysoitiin sisällönanalyysin keinoin. Tutkimustulosten myötä havaittiin, että stressin lievityksessä musiikin tärkeimmät piirteet…
Women's Emotions Towards the Mobile Phone
2012
The purpose of this study is to investigate whether women's emotions associate differently with the mobile phone depending on the type of family in which they live. James A. Russell's circumplex model of affect which explores four main emotional dimensions, excitement, distress, depression and contentment, was applied. The article is based on the female sub-sample (N = 3,704) of nationally representative survey data collected from Italy, France, the UK, Germany and Spain (N = 7,255) in 2009. The results show that it is women living in blended families who seem to associate more distress and less feelings of contentment with the mobile phone than women living in other types of family. peerRe…

A basic need theory approach to problematic Internet use and the mediating effect of psychological distress
2015
The Internet provides an easily accessible way to meet certain needs. Over-reliance on it leads to problematic use, which studies show can be predicted by psychological distress. Self-determination theory proposes that we all have the basic need for autonomy, competency, and relatedness. This has been shown to explain the motivations behind problematic Internet use. This study hypothesizes that individuals who are psychologically disturbed because their basic needs are not being met are more vulnerable to becoming reliant on the Internet when they seek such needs satisfaction from online activities, and tests a model in which basic needs predict problematic Internet use, fully mediated by p…
Diurnal Cycle Relationships between Passive Fluorescence, PRI and NPQ of Vegetation in a Controlled Stress Experiment
2017
In order to estimate vegetation photosynthesis from remote sensing observations; some critical parameters need to be quantified. From all absorbed light; the plant needs to release any excess that is not used for photosynthesis; by non-photochemical quenching; by fluorescence emission and unregulated thermal dissipation. Non-photochemical quenching (NPQ) processes are controlled photoprotective mechanisms which; once activated; strongly control the dynamics of photochemical efficiency. With illumination conditions increasing and decreasing during a diurnal cycle; photoprotection mechanisms needs to change accordingly. The goal of this work is to quantify dynamic NPQ; measured from active fl…
Apmierinātība ar partnerattiecībām un uztvertais stress saplūdušās un nukleārās ģimenēs.
2021
Bakalaura darba mērķis ir noskaidrot, kādas atšķirības apmierinātībā ar partnerattiecībām un uztverto stresu pastāv starp indivīdiem nukleārās un saplūdušās ģimenēs. Pētījuma izlasi veido 610 indivīdi, no kuriem 430 ir partnerattiecībās nukleārā ģimenē un 180 — saplūdušā ģimenē. Darbā tiek izmantotas divas aptaujas: Apmierinātība ar partnerattiecībām un Uztvertā stresa skala. Pētījuma rezultāti liecina, ka nav statistiski nozīmīgas atšķirības starp salīdzināmajām grupām attiecībā uz apmierinātību ar partnerattiecībām un uztverto stresu. Rezultāti atklāj statistiski nozīmīgas sakarības starp apmierinātību ar partnerattiecībām un uztverto stresu, proti, palielinoties uztvertajam stresam, sama…
