Delayed Motherhood Decreases Life Expectancy of Mouse Offspring1

2005

Abstract This study analyzes the long-term effects of delayed motherhood on reproductive fitness and life expectancy of offspring in the mouse. Hybrid (C57BL/6JIco × CBA/JIco) first-generation (F1) females, either at the age of 10 or 51 wk, were individually housed with a randomly selected 12- to 14-wk-old hybrid male following a breeding pen system until females reached the end of their reproductive life. Reproductive fitness of second-generation (F2) females was tested from the age of 25 wk until the end of their reproductive life. In F2 males, the testing period ranged from the age of 52 wk until their natural death. Delayed motherhood of hybrid F1 female mice was associated with a decre…

Objectively recorded physical activity in early pregnancy: A multiethnic population-based study

2012

This study aimed to compare objectively recorded physical activity (PA) levels and walking steps among pregnant women. Cross-sectional data from a multiethnic cohort (n = 823) of pregnant women consisting of 44% from Western countries, 24% from South Asia, 14% from Middle East, and 18% from other countries. PA and steps were recorded by the activity monitor SenseWear™ Pro3 Armband. A total of 678 women were included in the analysis. Western women walked significantly more steps and had higher moderate-to-vigorous-intensity physical activity (MVPA) levels compared with South Asian women per weekday and weekend day. Interaction terms (P = 0.008) between ethnicity (Western vs South Asian) and …

The Cave of Vecchiuzzo: anthropology, paleopathology and hierarchy of the human group with a statistical overview (Petralia Sottana – Palermo, Italy)

2013

Lo scavo della Grotta del Vecchiuzzo fu il primo effettuato nelle Madonie (Sicilia centrooccidentale). Fin dalla sua scoperta avvenuta per mano di Collisani e Carapezza nel 1936, il ritrovamento di manufatti nel vano principale indicò che la grotta era stata abitata. Gli scavi, effettuati a partire dal 1937, indicarono che la grotta era stata adibita ad abitazione o forse a santuario e che era stata abitata intorno al terzo millennio a.C. I resti scheletrici, attribuiti ad almeno quindici individui, sono stati studiati dal punto di vista antropologico, antropometrico e paleopatologico, combinando metodologie tradizionali a quelle più moderne. Sui dati odontometrici raccolti è stata effettua…

La bombe démographique en question

2014

International audience; La menace de la « bombe démographique », la marche supposée inexorable vers le surpeuplement, obsède nos sociétés depuis cinquante ans. La population croît, partout et surtout là où les hommes sont les plus fragiles. Pourtant, l’histoire enseigne que de graves crises ont régulièrement perturbé cette croissance, et si l’on se tourne vers l’avenir, la population mondiale n’apparaît pas non plus comme un flot incontrôlable : peut-on encore opposer les schémas simplistes de la démographie des pays développés et de ceux du Tiers monde, au regard des évolutions récentes ? Le modèle de la « transition démographique » est-il encore valide ? Cet essai entend dénoncer les idée…

On the genetics of psoriasis

1973

To elucidate the mode of inheritance in psoriasis, Falconer's model for estimating heritability which is under the assumption of multifactorial inheritance, was applied to the data of Hellgren (1967) from Sweden. The heritability estimates were based on both manifest and potential psoriasis since a clear separation of these two categories was impossible. These estimates were 64% for parents, 60% for siblings and 52% for all first degree relatives which included the children of psoriatic cases. For second degree relatives it was 48%. None of these differences are statistically significant. The results are discussed.

Long-term patterns of effort-reward imbalance and over-commitment: Investigating occupational well-being and recovery experiences as outcomes

2013

The aim of this study was, first, to identify long-term patterns of effort-reward imbalance (ERI) and over-commitment (OVC), and, second, to examine how occupational well-being (burnout, work engagement) and recovery experiences (psychological detachment, relaxation, mastery and control) differ in these patterns. The study was based on follow-up data with three measurement points (2006, 2008, 2010) collected from Finnish managers (N=298). Latent Profile Analysis resulted in five long-term ERI-OVC patterns: a high-risk pattern (high ERI, high OVC), found in 20% of the participants; a low-risk pattern (low ERI, low OVC), found in 24% of participants; a relatively low-risk pattern (low ERI, mo…

A diversity of patterns: 10-year trajectories of men and women diagnosed with psychosis for the first time. A time-geographic approach

2020

People with severe mental illness face a different interventional landscape compared to some decades ago, when mental hospitals were dominant, in Sweden as well as in the rest of the Western world. The aim of the research reported in this article was to follow men and women diagnosed with psychosis for the first time over a 10-year period, and to explore what interventions they experienced. The interventions, here defined as "spheres", were either community-based or institutional. A third sphere represents no interventions. Based on data from registers and using a time-geographic approach, the individuals were visualised as 10-year trajectories where their transitions between the different …
