Physical Activity and Nutrition INfluences In ageing (PANINI): consortium mission statement
2018
First paragraph: Current demographic trends indicate that by the year 2020, almost one in five of the European population will be aged 65 years or over. Although life expectancy is increasing by 2 years per decade, the period of life spent in good health is not keeping pace and most Europeans spend their last decade in poor health. Consequently, there is an urgent need to understand how lifestyle factors can influence age-related changes from gene to society level and how they may be integrated into a net effect of healthy ageing. It is also crucial to develop and validate interventions and health policies to ensure that more of our older adults have a healthy and active later life. This is…
Trematode cercariae as prey for zooplankton: effect on fitness traits of predators.
2019
AbstractRemoval of parasite free-living stages by predators has previously been suggested an important factor controlling parasite transmission in aquatic habitats. Experimental studies of zooplankton predation on macroparasite larvae are, however, scarce. We tested whether trematode cercariae, which are often numerous in shallow waters, are suitable prey for syntopic zooplankters. Feeding rates and survival of freshwater cyclopoids (Megacyclops viridis, Macrocyclops distinctus), calanoids (Arctodiaptomus paulseni), cladocerans (Sida crystallina) and rotifers Asplanchna spp., fed with cercariae of Diplostomum pseudospathaceum, a common fish trematode, were studied. In additional long-term e…
Jyväskyläläisten ravintoloiden anniskeluoikeudet ja valvonta 1932-1939
2015
Epäonnistuneen kieltolain myötä Suomeen laadittiin itsenäisyyden ajan ensimmäinen väkijuomalaki. Väkijuomalain myötä yksityiset henkilöt, yhdistykset, järjestöt sekä yksityiset kerhot saattoivat perustaa anniskeluravintoloita. Tässä tutkielmassa tarkastellaan Jyväskyläläisiä anniskeluravintoloiden anniskeluoikeusprosessia ja ravintoloiden valvontaa kieltolain päättymisestä vuonna 1932 talvisodan syttymiseen syystalvella vuonna 1939. Yhteiskunta oli sisällissodan myötä edelleen jakaantunut. Myös Alkoholiliike jakoi ravintolat yhteiskuntaluokkien mukaan. Tutkielman ensimmäisenä tavoitteena on selvittää, miten anniskeluoikeutta haettiin ja millaiset jyväskyläläiset ravintolat oikeutta hakivat …
Diet Macronutrient Composition, Physical Activity, and Body Composition in Soldiers During 6 Months Deployment
2018
Abstract Introduction Optimal diet together with good physical fitness maintains readiness and military performance during longer deployments. The purpose of this study was to describe changes in dietary macronutrient and energy intake, total physical activity and body composition during a 6-month deployment in South Lebanon. Furthermore, associations of diet macronutrient intake and physical activity on body composition were also studied. Materials and Methods Forty male soldiers kept a 3-day food diary and their body composition was measured via bioimpedance and ultrasonography. Total physical activity was evaluated by accelerometers in a subgroup of participants. Measurements were conduc…
Development of a Food-Based Diet Quality Score from a Short FFQ and Associations with Obesity Measures, Eating Styles and Nutrient Intakes in Finnish…
2019
We constructed a food-based diet quality score (DQS) and examined its association with obesity measures, eating styles and nutrient intakes. Participants were 3592 individuals (764 dizygotic [DZ] and 430 monozygotic [MZ] twin pairs) from the FinnTwin16 study. The DQS (0&ndash
Disparities in nutritional adequacy of diets between different socioeconomic groups of Finnish adults
2022
Information on dietary adequacy is needed to assess food and nutrition security in a modern society, especially in the transition towards climate-friendly food systems. In this study, differences in the nutritional adequacy of diets among Finnish adults were evaluated in population groups of different education, income and urbanisation levels. The study used data from the FinDiet 2017 Survey (n = 1655, 18–74 years). Modelled usual intakes of foods and nutrients were evaluated relative to food-based dietary guidelines issued by the National Nutrition Council of Finland (FNNC) and with respect to nutrient adequacy following the Nordic Nutrition Recommendations and FNNC. For about half of the …
Assessing the influence of confounding biological factors when estimating bioaccumulation of PCBs with passive samplers in aquatic ecosystems
2017
Passive samplers are promising surrogates for organisms, mimicking bioaccumulation. However, several biological characteristics disturb the passive partitioning process in organisms by accelerating or restraining bioaccumulation, resulting in species-specific body residues of hydrophobic organic contaminants (HOCs). In addition to site-specific characteristics and HOC concentrations, age, sex, diet, biotransformation capability and habitat-specific characteristics may affect body residues. Two passive sampler types, polyethylene (PE) and polydimethylsiloxane (PDMS) were deployed in a PCB-contaminated freshwater lake water and sediment, respectively, to assess their bioaccumulation predictio…
Kilpailu vaikuttaa nieriän ravintoon
2013
Lapin nieriäkannat ovat monin paikoin taantuneet uusien kalalajien levittäytymisen seurauksena. Tuore väitöskirjatutkimus osoittaa, että nieriä voi vaihtaa ravintoaan ja elinpaikkaansa vähentääkseen kilpailua muiden kalalajien kanssa. nonPeerReviewed
"You look delicious" : food, eating, and hunger in Margaret Atwood's novels
2007
FM Johanna Lahikaisen naistutkimuksen väitöskirjan ””You look delicious”. Food, Eating, and Hunger in Margaret Atwood’s Novels” (”Näytät herkulliselta”. Ruoka, syöminen ja nälkä Margaret Atwoodin romaaneissa) tarkastustilaisuus. Vastaväittäjänä dosentti Päivi Kosonen (Tampereen yliopisto) ja kustoksena dosentti Eeva Jokinen. Kanadalainen Margaret Atwood on palkittu ja rakastettu kirjailija ympäri maailman. Atwood on todennut, että ruoka ja syöminen ovat elämämme perustavia ja ensimmäisiä asioita. Me syömme ennen kuin ymmärrämme kieltä, sukupuoltamme tai kansallisuuttamme. Ehkä hieman ilkikurisesti Atwood väittää, että ateriat ovat kirjallisuuden peruselementtejä: lähes yhtä yleisiä ja tärke…
A modified niche model for generating food webs with stage-structured consumers : The stabilizing effects of life-history stages on complex food webs
2021
1. Almost all organisms grow in size during their lifetime and switch diets, trophic positions, and interacting partners as they grow. Such ontogenetic development introduces life-history stages and flows of biomass between the stages through growth and reproduction. However, current research on complex food webs rarely considers life-history stages. The few previously proposed methods do not take full advantage of the existing food web structural models that can produce realistic food web topologies. 2. We extended the niche model by Williams & Martinez (2000) to generate food webs that included trophic species with a life-history stage structure. Our method aggregated trophic species …
