Divergent Patterns and Trends in Breast Cancer Incidence, Mortality and Survival Among Older Women in Germany and the United States
2020
Background: Breast cancer treatment has changed tremendously over the last decades. In addition, the use of mammography screening for early detection has increased strongly. To evaluate the impact of these developments, long-term trends in incidence, mortality, stage distribution and survival were investigated for Germany and the United States (US). Methods: Using population-based cancer registry data, long-term incidence and mortality trends (1975&ndash
Working hours – tracking the current and future trends
2021
It is important to track the trends of future working hours, since working hours have strong associations to everyday life and work-life interaction, but also to health. In this paper we aim to track the current and future trends in working hours. We discuss the trends through the key dimensions of working hours: the length, timing, tempo and autonomy. We also consider the role of current trends of spatial changes of work. Changes in working time patterns are fostered by several driving factors: globalization and business restructuring challenging the current work organizations, new information technologies, demographic and climate change and the current and future pandemics. The past and c…
Co-parental Couples and New Families: A Study of the Primary Triad
2015
Abstract Starting from current areas of research in the field of developmental theories, the aim of this work is to analyse parent-child interactions within a primary triad and to consider co-parenting couple and their children as an interactive matrix. In particular, parent-child relationship could be observed trough new developmental units of observation and coding systems in the multiple scenarios of new families. The deepening of this study may promote an effective connection between research and educational support as well as clinical work with families and parental couples.
Attività anti-proliferativa di derivati di organostagno(IV) con Na-Boc-Ornitina e studio dell’azione pro-apoptotica del derivato Ph3Sn(Boc- Orn)
2013
Nuovi composti di organostagno(IV) [R3SnL e R¢2SnL2 (R = Me, Ph e R¢= Me, nBu, HL= Na-Boc-Ornitina)] sono stati sintetizzati e caratterizzati sia allo stato solido (FT-IR) che in soluzione (1H e 13C NMR) per poterne valutare la citotossicità in linee cellulari tumorali [1]. Na-Boc-Ornitina si comporta come un legante chelante dello stagno con il gruppo carbossilato, mentre il gruppo amminico Na-protetto è esente dalla coordinazione. I composti sono stati testati per l’attività citotossica in vitro su cellule neoplastiche umane HepG2 di epatocarcinoma ed MCF7 di cancro al seno. L’effetto dei composti, nel range da 0.5 a 25 μM, dopo 24 h di incubazione è stato valutato mediante saggio MTT. Il…

Exploring the Relationship Between Trust and Business Start-Ups in 52 Countries Over 16 Years
2021
A well-functioning social network involves attributes such as honesty, benevolence, fairness and confidence. When this network – trust - has formed, participants can count on reliable and consistent economic transactions. This has the effect of higher level of co-operation, but also co-dependence. Strong social networks, as measured in this study by the degree of interpersonal trust and trust in institutions, are foundational elements for societies wishing to progress to new higher levels of entrepreneurship and development. In a pooled OLS of up to 52 countries and 16 years, this study estimates how changes in interpersonal trust and trust in institutions affect new business creation. The …
Identification of mycorrhiza-regulated genes with arbuscule development-related expression profile
2004
Suppressive subtractive hybridisation was applied to the analysis of late stage arbuscular mycorrhizal development in pea. 96 cDNA clones were amplified and 81, which carried fragments more than 200 nt in size, were sequence analysed. Among 67 unique fragments, 10 showed no homology and 10 were similar to sequences with unknown function. RNA accumulation of the corresponding 67 genes was analysed by hybridisation of macro-arrays. The cDNAs used as probes were derived from roots of wild type and late mutant pea genotypes, inoculated or not with the AM fungus Glomus mosseae. After calibration, a more than 2.5-fold mycorrhiza-induced RNA accumulation was detected in two independent experiments…
In-depth characterization of denitrifier communities across different soil ecosystems in the tundra
2022
Abstract Background In contrast to earlier assumptions, there is now mounting evidence for the role of tundra soils as important sources of the greenhouse gas nitrous oxide (N2O). However, the microorganisms involved in the cycling of N2O in this system remain largely uncharacterized. Since tundra soils are variable sources and sinks of N2O, we aimed at investigating differences in community structure across different soil ecosystems in the tundra. Results We analysed 1.4 Tb of metagenomic data from soils in northern Finland covering a range of ecosystems from dry upland soils to water-logged fens and obtained 796 manually binned and curated metagenome-assembled genomes (MAGs). We then sear…

Work Stressors and Intention to Leave the Current Workplace and Profession: The Mediating Role of Negative Affect at Work.
2022
The first aim of this study was to determine whether organisational constraints, interpersonal conflicts at work, workload and negative affect at work have a positive relationship with intention to leave a current job or profession. The second aim was to investigate whether negative affect at work mediates the relationship between work stressors and intention to leave a current job or profession. The study was a quantitative cross-sectional design in nature. Data were collected between March and April 2022. The sample consisted of 306 midwives working in the Polish public health service. The theoretical model was tested using structural equation modelling. The results confirmed positive dir…
