Psychomotor speed in a random sample of 7,979 subjects aged 30 years and over.
2011
Background and aims: Slowing of psychomotor speed among older individuals has been shown in numerous studies. However, in most cases these studies were based on small and selected groups of people and, in some cases, the test procedures did not allow separation of decision time and motor components of the overall performance. The purpose of the present study was to analyse in a large, randomly selected population sample the differences in decision and movement times in simple and multiple-choice test conditions. The association of educational background with psychomotor speed was also examined. Methods: Data on psychomotor speed were collected from a representative nation-wide sample of the…
Life-space mobility assessment in older people in Finland; measurement properties in winter and spring.
2014
Background: Life-space mobility refers to the spatial area an individual moves through, the frequency and need for assistance. Based on the assumption that measurement scale properties are context-specific, we tested the scale distribution, responsiveness, and reproducibility of the 15-item University of Alabama at Birmingham Study of Aging Life-Space Assessment in older people in Finland, specifically accounting for season. Methods: Community-dwelling older men and women in cent ral Finland aged 75-90 y ears were interviewed to determine life-space mobility (score range 0-120). Baseline (January-June 2012) and one-year follow-up data (January-June 2013; n = 806) from the cohort study “ Lif…
Mobility difficulties and physical activity as predictors of mortality and loss of independence in the community-living older population.
2000
OBJECTIVE: In older people, mobility impairments and physical inactivity are risk factors for further disability and death. We studied the interaction of physical activity and mobility impairment as a predictor of dependence and mortality. DESIGN: A population-based, prospective study. The data were collected in structured interviews in the year 1988 and 8 years later in the year 1996 as part of the Evergreen Project. PARTICIPANTS: Subjects were 1109 independently living, at baseline 65- to 84-year-old people in the city of Jyvaskyla, in central Finland. METHODS: Participants were ranked into four groups: (1) Intact mobility and physically active (Mobile-Active), (2) Intact mobility and sed…
Difficulties in mobility among elderly people and their association with socioeconomic factors, dwelling environment and use of services.
1995
The purpose of this study was to clarify the extent to which elderly people have difficulties in mobility, and determine their association with socioeconomic factors, dwelling environment and use of services. The study groups were composed of two random samples of 800 persons aged 65–74 and 75–84, respectively. In all, 1224 non- institutionalized persons (80%) were interviewed at home. The respondents were asked to assess their ability to get about the house, negotiate stairs and walk outdoors, as well as manage certain physical exercise tasks. Difficulties in getting about outdoors were found most frequently among the women in the older age group (52% reported difficulties), and least freq…
Reduced mobility and physical activity as predictors of depressive symptoms among community-dwelling older adults: an eight-year follow-up study.
2003
Background and aims: Epidemiological research suggests that reduced physical activity and mobility may be associated with depressive symptoms. The present study examines the relative roles of mobility status and physical activity as predictors of depressive symptoms among community-dwelling older adults. Methods: The subjects comprised randomly selected, non-institutionalized residents of the city of Jyvaskyla, central Finland, born in 1904–1923. At baseline, 80% (N=1224) and after the 8-year follow-up period (1996) 88% (N=663) of eligible persons were interviewed. All non-institutionalized men and women (N=384) who participated in both baseline and follow-up interviews, who supplied data o…
Investigation of antihypertensive class, dementia, and cognitive decline: a meta-analysis
2020
ObjectiveHigh blood pressure is one of the main modifiable risk factors for dementia. However, there is conflicting evidence regarding the best antihypertensive class for optimizing cognition. Our objective was to determine whether any particular antihypertensive class was associated with a reduced risk of cognitive decline or dementia using comprehensive meta-analysis including reanalysis of original participant data.MethodsTo identify suitable studies, MEDLINE, Embase, and PsycINFO and preexisting study consortia were searched from inception to December 2017. Authors of prospective longitudinal human studies or trials of antihypertensives were contacted for data sharing and collaboration.…

Effects of primary- and secondary-treated bleached kraft mill effluents on the immune system and physiological parameters of roach.
2000
The present study was designed to examine, whether, effluents from a modern pulp and paper mill using elemental chlorine-free/total chlorine-free (ECF/TCF) bleaching, exert effects on the immune system of fish and, in addition, to relate these findings to physiological parameters known to be affected by bleached kraft-mill effluents (BKME). Roach (Rutilus rutilus) were exposed in laboratory conditions to primary- or secondary-treated effluent from a pulp and paper mill. In order to study their capability to respond to foreign antigens they were immunised with bovine gamma-globulin (BGG) prior to exposure. The number of anti-BGG antibody-secreting cells (ASC) and the number of immunoglobulin…
Seabirds mated for life migrate separately to the same places: behavioural coordination or shared proximate causes?
2015
Long-term pair bonds occur in diverse animal taxa, but they are most common in birds, and can last from a few years to a lifetime. In many of these species, after the reproductive season, birds migrate to distant nonbreeding grounds where they remain for several months, and until recently, little was known about whether partners maintain contact during migration. This gap in knowledge was primarily due to past methodological difficulties in tracking long-term, large-scale movements of individuals. However, the development of new animal-borne geolocation devices has enabled researchers to track movements of individuals for a year or more. We tracked the annual migrations of both members of b…
Synthesis and Supramolecular Association of Immobilized NCN-Pincer Platinum(II) Complexes on Hyperbranched Polyglycerol Supports
2004
Pertosylation of hyperbranched polyglycerol (M(n)=2000; M(w)/M(n)=1.3) followed by partial displacement of the tosyl groups with carboxylic acid functionalized NCN-pincer platinum(II) complexes [PtI-2,6-(NMe(2)CH(2))(2)C(6)H(2)-4-COOH], resulted in covalent attachment of the NCN-pincer complexes to the polyglycerol. These functionalized hyperbranched macromolecules have been characterized by (1)H, (13)C, and (195)Pt NMR, UV-visible, and IR spectroscopy. The presence of Pt and I atoms renders them directly visible by transmission electron microscopy (TEM) without staining procedures, which offers images of associated hyperbranched macromolecules. TEM micrographs show disk-shaped structures w…
