Characterization of sulfhydryl oxidase from Aspergillus tubingensis
2017
Background Despite of the presence of sulfhydryl oxidases (SOXs) in the secretomes of industrially relevant organisms and their many potential applications, only few of these enzymes have been biochemically characterized. In addition, basic functions of most of the SOX enzymes reported so far are not fully understood. In particular, the physiological role of secreted fungal SOXs is unclear. Results The recently identified SOX from Aspergillus tubingensis (AtSOX) was produced, purified and characterized in the present work. AtSOX had a pH optimum of 6.5, and showed a good pH stability retaining more than 80% of the initial activity in a pH range 4-8.5 within 20 h. More than 70% of the initia…
The swinholide biosynthesis gene cluster from a terrestrial cyanobacterium, Nostoc sp. strain UHCC 0450
2017
ABSTRACT Swinholides are 42-carbon ring polyketides with a 2-fold axis of symmetry. They are potent cytotoxins that disrupt the actin cytoskeleton. Swinholides were discovered from the marine sponge Theonella sp. and were long suspected to be produced by symbiotic bacteria. Misakinolide, a structural variant of swinholide, was recently demonstrated to be the product of a symbiotic heterotrophic proteobacterium. Here, we report the production of swinholide A by an axenic strain of the terrestrial cyanobacterium Nostoc sp. strain UHCC 0450. We located the 85-kb trans -AT polyketide synthase (PKS) swinholide biosynthesis gene cluster from a draft genome of Nostoc sp. UHCC 0450. The swinholide …
Transcriptional Upregulation of DNA Damage Response Genes in Bank Voles (Myodes glareolus) Inhabiting the Chernobyl Exclusion Zone
2018
Exposure to ionizing radiation (IR) from radionuclides released into the environment can damage DNA. An expected response to exposure to environmental radionuclides, therefore, is initiation of DNA damage response (DDR) pathways. Increased DNA damage is a characteristic of many organisms exposed to radionuclides but expression of DDR genes of wildlife inhabiting an area contaminated by radionuclides is poorly understood. We quantified expression of five central DDR genes Atm, Mre11, p53, Brca1, and p21 in the livers of the bank vole Myodes glareolus that inhabited areas within the Chernobyl Exclusion Zone (CEZ) that differed in levels of ambient radioactivity, and also from control areas ou…
The effects of fractional CO2 laser, Nano-hydroxyapatite and MI paste on mechanical properties of bovine enamel after bleaching
2017
Background This study investigated the effect of post bleaching treatments to the change of enamel elastic modulus and microhardness after dental bleaching in- vitro. Material and Methods Fifty bovine incisor slab were randomly assigned into five groups (n=10). The samples were bleached for three times; 20 minutes each time, by 40% hydrogen peroxide. Next it was applied fractional CO2 laser for two minutes, Nano- hydroxy apatite (N-HA) and MI-paste for 7 days and 2 minutes per day. The sound enamel and bleached teeth without post treatment remained as control groups. The elastic modulus and microhardness were measured at three times; 24 hours, 1 and 2 months. Data were statistically analyze…
Narratives of Burnout and Recovery from an Agency Perspective : A Two-Year Longitudinal Study
2017
Abstract Purpose To provide knowledge about the recovery process during rehabilitation and two years later by exploring the manifestation of agency and spheres of meaning in the narratives of participants in a national rehabilitation course. Material and methods The subjects of the study were four participants in a national rehabilitation course, whose burnout levels had decreased between the initial and follow-up periods of the course. Semi-structured interviews on two occasions and an electronic questionnaire 1.5 years post rehabilitation comprised the main material. In addition, the BBI -15 (Bergen Burnout Indicator) and DEPS-screen were used. Results Thematic narrative analysis revealed…
‘Celebrating diverse motherhood’: physically disabled women’s counter-narratives to their stigmatised identity as mothers
2018
This study examined how disabled women negotiated their stigmatised identity as mothers by presenting counter-narratives to the culturally dominant narrative of disabled motherhood. Eleven Finnish physically disabled mothers were interviewed. The data were analysed by focusing on these counter-narratives, their linguistic features and their functions in the interviews. The disabled mothers produced four types of counter-narratives about their motherhood experiences: (1) celebrating diverse motherhood through individual coping; (2) performing motherhood through collaborative caring; (3) boosting motherhood through praising one’s children; and (4) normalising (disabled women’s) motherhood thr…
Empowerment as an affective-discursive technology in contemporary capitalism: insights from a play
2019
Over recent years, an increasing body of research in social and cultural studies has investigated the contemporary processes of social change from the point of view of affective capitalism. In this article, we take under scrutiny one of its technologies, namely, empowerment, by which we mean a state characterised by feelings of strength, ability and power that enable agency. More specifically, we investigate the way empowerment is presented in a cultural product, a play that tells a story about personnel training in a factory, shown in a city theatre in Finland. By linking recent theorisation of affective capitalism with an investigation of the intertextual and interdiscursive relations of …
How do people talk decades later about their crisis that we call psychosis? : A qualitative study of the personal meaning-making process
2019
Psychosis refers to a severe mental state that often significantly affects the individual’s life course. However, it remains unclear how people with the lived experiences themselves view these phenomena, as part of their life story. In order to evaluate this personal meaning-making process, we conducted in-depth life-story interviews with 20 people who had been diagnosed with non-affective psychosis 10 to 23 years previously in one catchment area. 35% of them were still receiving mental health treatment, and 55% of them were diagnosed with schizophrenia. Only a minority named their experiences as psychosis. On the basis of narrative analysis, two types of stories appeared to encompass how m…
Social interaction in management group meetings: a case study of Finnish hospital.
2016
Purpose – The purpose of this paper is to understand the role of management group meetings (MGMs) in hospital organization by examining the social interaction in these meetings. Design/methodology/approach – This case study approaches social interaction from a structuration point of view. Social network analysis and qualitative content analysis are applied. Findings – The findings show that MGMs are mainly forums for information sharing. Meetings are not held for problem solving or decision making, and operational coordinating is limited. Meeting interaction is very much focused on the chair, and most of the discussion takes place between the chair and one other member, not between members…
