Alexithymia as a Predictor of Arousal and Affect Dysregulations when Batterers with Attention Deficit Hyperactivity Disorder Cope with Acute Stress

2020

Empirical research has stated that Attention Deficit Hyperactivity Disorder (ADHD) might underlie intimate partner violence against women (IPVAW) perpetration. Even though there is a clear relationship between these two variables, it is still unknown how ADHD facilitates violence proneness. In this regard, psychophysiological variables such as skin conductance levels (SCL) might offer information about emotional regulation when individuals cope with stress. Furthermore, alexithymia traits might be a strong candidate in explaining the above-mentioned emotional dysregulations. Hence, we compared the SCL response to acute cognitive stress in IPVAW perpetrators with and without ADHD symptoms to…

Loneliness Mediates the Relationship Between Early Life Stress and Perceived Stress but not Hypothalamic–Pituitary–Adrenal Axis Functioning

2021

Many authors have proposed that early life stress (ELS) provokes a dysregulation of the hypothalamic–pituitary–adrenal (HPA) axis and contributes negatively to the management of stress in adulthood. However, these associations have not always been observed, making it necessary to include new factors that could explain the different results found. In this regard, people with ELS experiences report less social support during adulthood, suggesting that loneliness could be a mediating factor. Thus, our aims were to investigate whether ELS was related to both perceived stress and diurnal HPA axis activity, and whether loneliness mediates these relationships, in a community sample (N=187, 18–55ye…

Ambient Air Pollution Increases the Risk of Cerebrovascular and Neuropsychiatric Disorders through Induction of Inflammation and Oxidative Stress

2020

Exposure to ambient air pollution is a well-established determinant of health and disease. The Lancet Commission on pollution and health concludes that air pollution is the leading environmental cause of global disease and premature death. Indeed, there is a growing body of evidence that links air pollution not only to adverse cardiorespiratory effects but also to increased risk of cerebrovascular and neuropsychiatric disorders. Despite being a relatively new area of investigation, overall, there is mounting recent evidence showing that exposure to multiple air pollutants, in particular to fine particles, may affect the central nervous system (CNS) and brain health, thereby contributing to …

Skolotāju apmierinātības ar darbu, stresa un pašefektivitātes sakarības skolotāju grupā

2018

No skolotāju apmierinātības ar darbu, stresa pārvarēšanas un pašefektivitātes ir atkarīga ne tikai viena konkrēta darbinieka, bet visas izglītības iestādes skolotāju un personāla labizjūta un pedagoģiskā darba efektivitāte kopumā. Pētījuma „Skolotāju apmierinātības ar darbu, stresa un pašefektivitātes sakarības skolotāju grupā” mērķis, saskaņā ar pasūtījumu, bija noskaidrot skolotāju apmierinātību ar darbu, darba stresa un pašefektivitātes sakarības un izstrādāt atbalsta pasākumus un rekomendācijas. Pētījumā piedalījās 46 respondenti ( sievietes - 89%) vecumā no 24 līdz 64 gadiem. Darba stāžs pedagogiem no 1 līdz 41 gadam (vidējais 18 gadi). Pētījumā tika izmantota kvalitatīvā metodes - daļ…

Moving on the trajectory : a qualitative study of new immigrants' acculturation in Finland

2015

With a steady growth of immigration in Finland, the current number of immigrants has reached nearly 6% of the total population. These immigrants have crossed cultural boundaries for a new home and better life in Finland, but often face the compound challenges of navigating a new culture while striving to function efficiently in an unfamiliar environment. Thus, the aim of this study is to investigate new immigrants’ acculturation in Finland. Previous studies have been focused on either refugees or returnees, so this study aims to produce an inclusive investigation of acculturation of on both forced and voluntary immigrants, as well as returnees who have engaged in the official integration pl…

Social support and well-being of refugees in Finland

2018

Objective: The objective of this study was to explore the impact of social support on acculturation process and its’ outcomes on the current mental and physical health of refugees resettling in Jyväskylä, Finland. Method: Data were gathered qualitatively. Eight participants of refugee back ground filled out a questionnaire assessing sociodemographic information and participated in semi-structured interviews. Two interviews were held individually and two focus-group ones. To analyse the data, qualitative thematic analysis was used. Results: Refugees settling in Finland evidenced experiences of acculturative stress. Participants had received social support both from formal and informal networ…

Role of nitric oxide synthase (NOS) of Klebsormidium nitens: Identification and characterization of partners

2021

National audience; Nitric oxide (NO) is an important cellular signaling molecule across kingdoms. During bioticor abiotic stresses, NO burst is detected in both plants and mammals although no sequenceencoding the well described mammalian NO synthase (NOS) is highlighted in plants. Comparedto terrestrial plants, some algae present transcripts encoding the NOS-like enzyme. Amongthem, Klebsormidium nitens the model alga to study the early transition step from aquatic algaeto land plants is found. As mechanisms governing NO synthesis and signaling in green lineageremain unclear, the study of NOS from K. nitens (KnNOS) through (i) the identification ofregulator proteins, (ii) the identification …

Characterisation of NO synthases from the alga Klebsormidium nitens

2022

Nitric oxide (NO) is an important cellular signaling molecule regulating various physiological processes, in both animals and plants. In animals, NO synthesis is mainly catalyzed by NO synthase (NOS) enzymes. In plants, NOS-like activities sensitive to mammalian NOS inhibitors have been measured, although no sequences encoding mammalian NOS have been found in land plants. Interestingly, we identified NOS-like sequences in about twenty algae species. These latter include the filamentous Charophyta green algae Klebsormidium nitens, a biological model to study the early transition step from aquatic algae to land plants. Currently, two NOS were identified in K. nitens genome: i) KnNOS1 which po…
