Postural balance and susceptibility to falls in older women : genetic and environmental influences in single and dual task situations

2006

This study was conducted to assess the contribution of genetic and non-genetic influences to postural balance while standing and walking under single and dual task conditions. Furthermore, the role of familial and non-familial influences in susceptibility to falls was examined. In addition, the validity of force platform balance tests as predictors of falls was elucidated.The present study was part of the Finnish Twin Study on Aging (FITSA). A population based sample of this study consisted of 206 monozygotic and 228 dizygotic female twins aged 63-76 years. Postural balance was assessed with force platform stance tests and walking tests. The balance tests were carried out as single tasks an…

Genetics of Skeletal Muscle Characteristics and Maximal Walking Speed among Older Female Twins

2006

The purpose of this study was to examine the contribution of genetic and environmental effects on individual differences in skeletal muscle characteristics and maximal walking speed. The aim was also to identify chromosomal areas that account for skeletal muscle characteristics and maximal walking speed and to study whether the regions are same for these traits.Maximal isometric muscle strength of different muscle groups (hand grip, knee extensor, and ankle plantar flexion), leg extensor power, lower leg muscle cross-sectional area (CSA) and maximal walking speed were measured in the laboratory from 103 monozygotic and 114 dizygotic female twin pairs 63-76 years of age and without severe di…

Perimän ja liikuntaharjoittelun vaikutus ulomman reisilihaksen lihassolutyyppeihin ja kapillarisaatioon

2008

Laine, Tanja 2008. Perimän ja liikuntaharjoittelun vaikutus ulomman reisilihaksen lihassolutyyppeihin ja kapillarisaatioon. Liikuntafysiologian kandidaatin tutkielma. Liikuntabiologian laitos, Jyväskylän yliopisto, 34s. Tutkimuksissa on havaittu, että perimä vaikuttaa lihassolutyyppien jakaumaan ja kapillaritiheyteen (Rico-Sanz ym. 2003). Monet tutkimukset ovat kuitenkin havainneet myös erityyppisten harjoitusten muokkaavan erityisesti II-tyypin solujen jakaumaa (mm. Liu ym. 2002) ja kasvattavan kapillaarien määrää (mm. Zoladz ym. 2005). Tämän tutkimuksen tarkoituksena onkin selvittää, määrittääkö perimä vai liikunta-aktiivisuus enemmän ihmisen lihassolutyyppijakaumaa ja kapillaaritiheyttä.…

Isoviha unohtuvana suullisena perinteenä

2013

Tutkimus käsittelee Isossakyrössä 1800-luvun lopulta 1960-luvun puoliväliin kerrottua perimä-tietoa isostavihasta. Isossakyrössä käytiin 19.2.1714 Napuen taistelu, jonka jälkeen katsotaan isonvihan ajan Suomessa alkaneen. Kasakat majailivat alueella sekä ryöstivät, kiduttivat ja tap-poivat ihmisiä. Tutkimuksessa selvitetään isostavihasta kertovan perimätiedon kertojien piirtei-tä, perimätiedon taakse kätkeytyvää mentaliteettia ja perimätiedon kuihtumista 1950-luvun jäl-keen. Aineistona tutkimuksessa käytetään Suomalaisen Kirjallisuuden Seuran Kansanrunousarkistoon lähetettyjä tarinoita, joita on kertynyt kilpakeruiden yhteydessä ja niiden ulkopuolella. Aineisto on koottu topografisesta. Kai…

Associations of Genetic Susceptibility to Alzheimer’s Disease with Adiposity and Cardiometabolic Risk Factors among Children in a 2-Year Follow-up St…

2018

We investigated the associations of genetic risk score (GRS) for Alzheimer’s disease and apolipoprotein E (APOE) ɛ variant with cardiometabolic risk factors during 2-year follow-up in children and whether body fat percentage (BF%) modify these associations. A population-based sample of 469 children (246 boys, 223 girls) at baseline and 398 children (201 boys, 197 girls) at 2-year follow-up participated in the study. Genotyping was performed using the Illumina Custom Infinium CardioMetabo BeadChip and the Illumina Infinium HumanCoreExome BeadChip. The GRS was calculated using information on nine independent gene variants available in our genomic data. We assessed BF%, waist circumference, in…

The complete mitochondrial genome of the wood tiger moth (Arctia plantaginis) and phylogenetic analyses within Arctiinae

2021

We report the assembly and annotation of the complete mitochondrial genome of the warningly-coloured wood tiger moth (Arctia plantaginis) and investigate its phylogenetic position within Arctiinae. The A.plantaginis mitogenome is 15,479 bp long with 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNA genes, and an A + T-rich region (D-loop). The phylogenetic analyses based on 13 protein-coding genes showed A.plantaginis clustering within a clade of species with white wings and yellow or red bodies. This result can be useful in understanding the evolution of coloration in Arctiid moths. Peer reviewed

Factors behind Leisure-Time Physical Activity Behavior Based on Finnish Twin Studies: The Role of Genetic and Environmental Influences and the Role o…

2014

Different approaches are being taken to clarify the role of various factors in the development of physical activity behaviors. Genetic studies are a new area of physical activity research and also the motives for physical activity have been widely studied. The purpose of this paper is to review the findings emerging from the longitudinal genetic studies on leisure-time physical activity and to evaluate the associations between motivational factors and leisure-time physical activity. The focus is to review recent findings of longitudinal Finnish twin studies. The results of the latest longitudinal Finnish twin studies point to the existence of age-specific genetic and environmental influence…
