Effects of a weight management program delivered by social media on weight and metabolic syndrome risk factors in overweight and obese adults: A rand…
2017
Author(s): Jane, Monica; Hagger, Martin; Foster, Jonathan; Ho, Suleen; Kane, Robert; Pal, Sebely | Abstract: IntroductionThe aim of this project was to evaluate the effectiveness of using social media to augment the delivery of, and provide support for, a weight management program delivered to overweight and obese individuals during a twenty four week intervention.MethodsParticipants randomly divided into either one of two intervention groups or a control group. The two intervention groups were instructed to follow identical weight-management program. One group received the program within a Facebook group, along with a support network with the group, and the other intervention group receive…
Fat oxidation at rest and during exercise in male monozygotic twins
2019
Abstract Purpose We aimed to investigate if hereditary factors, leisure-time physical activity (LTPA) and metabolic health interact with resting fat oxidation (RFO) and peak fat oxidation (PFO) during ergometer cycling. Methods We recruited 23 male monozygotic twin pairs (aged 32–37 years) and determined their RFO and PFO with indirect calorimetry for 21 and 19 twin pairs and for 43 and 41 twin individuals, respectively. Using physical activity interviews and the Baecke questionnaire, we identified 10 twin pairs as LTPA discordant for the past 3 years. Of the twin pairs, 8 pairs participated in both RFO and PFO measurements, and 2 pairs participated in either of the measurements. We quantif…
Is Aquaponics Beneficial in Terms of Fish and Plant Growth and Water Quality in Comparison to Separate Recirculating Aquaculture and Hydroponic Syste…
2022
Aquaponics is a technique where a recirculating aquaculture system (RAS) and hydroponics are integrated to grow plants and fish in a closed system. We investigated if the growth of rainbow trout (Oncorhynchus mykiss) and baby spinach (Spinacia oleracea) would be affected in a coupled aquaponic system compared to the growth of the fish in RAS or plants in a hydroponic system, all systems as three replicates. We also investigated the possible effects of plants on the onset of nitrification in biofilters and on the concentration of off-flavor-causing agents geosmin (GSM) and 2-methylisoborneol (MIB) in rainbow trout flesh and spinach. For the fish grown in aquaponics, the weight gain and speci…
The effect of high-intensity interval exercise program on blood lipids and hormones in recreationally active adults
2015
Johdanto. Tyypin 2 diabetes sekä verenkieroelimistön sairaudet ovat yleistyneet ja niiden tehokkaimpana ehkäisynä pidetään liikuntaa. Suomessa ihmiset eivät noudata liikuntasuosi-tuksia ja syyksi inaktiivisuuteen sanotaankin olevan ajan ja motivaation puute. Korkeate-hoinen intervalliharjoittelu on ollut suosittua siksi, että se säästää aikaa ja sen vaikutuksien terveyteen ja kuntoon ajatellaan olevan vähintäänkin samanlaiset kun aerobisen harjoittelun. Tämän tutkimuksen tarkoituksena oli tutkia onko kahden erityyppisen intervalliharjoittelun (juoksu ja kuntopiiri) välillä eroja veren lipideissä ja hormoneissa, kun työmäärä ja intensiteetti pysyvät samana. Tällä hetkellä tutkimuksia tästä a…
Gut Microbiota and Serum Metabolome in Elite Cross-Country Skiers : A Controlled Study
2022
Exercise has been shown to affect gut the microbiome and metabolic health, with athletes typically displaying a higher microbial diversity. However, research on the gut microbiota and systemic metabolism in elite athletes remains scarce. In this study, we compared the gut microbiota profiles and serum metabolome of national team cross-country skiers at the end of an exhausting training and competitive season to those of normally physically-active controls. The gut microbiota were analyzed using 16S rRNA amplicon sequencing. Serum metabolites were analyzed using nuclear magnetic resonance. Phylogenetic diversity and the abundance of several mucin-degrading gut microbial taxa, including Akker…
Effects of perilipin I & V on the phenotype of zebrafish embryos
2012
Tämä Pro Gradu-tutkielma on tehty yhteistyössä Tampereen yliopiston Biolääketieteel- lisen teknologian yksikön kanssa. Tutkimuksen tarkoituksena oli selvittää perilipiinien vaikutusta seeprakalan fenotyyppiin käyttäen tutkimusmenetelminä geenien hiljentämistä ja mikroskopiaa. Geenit säätelevät proteiinien tuotantoa elimistössä. Jokaista proteiinia koodaa geeni, jonka toimintaan puuttumalla voidaan esimerkiksi estää kyseisen proteiinin muodos- tuminen. Morfoliinot ovat oligonukleotideja, joiden avulla voidaan tilapäisesti estää geenien toimintaa. Tässä työssä hiljennettiin morfoliinojen avulla kaksi geeniä seep- rakaloilta: perilipiini 1 ja perilipiini 5. Perilipiinit ovat lipidien varastoit…
Inter‐individual variation in responses to resistance training in cardiometabolic health indicators
2020
Abstract Resistance training (RT) may improve metabolic health; however, the extent of its effectiveness is constantly evaluated to assess improvements in the group means, thus obscuring the heterogeneous individual effects. This study investigated inter‐individual variation in responses to RT as reflected in metabolic health indicators and how age, sex, nutrition and pre‐training phenotypes are associated with such variabilities. Methods Previously collected data of men and women (39‐73 years, 135 trained, 73 non‐trained controls) were pooled for analysis. Measurements were taken twice before training to estimate individual day‐to‐day variations and measurement errors (n=208). The individu…
The influence of lipid content and taxonomic affiliation on methane and carbon dioxide production from phytoplankton biomass in lake sediment
2021
The greenhouse gases methane (CH4) and carbon dioxide (CO2) are end products of microbial anaerobic degradation of organic matter (OM) in lake sediments. Although previous research has shown that phytoplankton lipid content influences sediment methanogenesis, current understanding on how OM quality affects methanogenesis is still limited. Such information is needed to more accurately assess how lake greenhouse gas emissions may change in response to anthropogenic activities. We cultured 11 phytoplankton species from five classes and studied how taxonomic identity, C : N ratio, lipid content, and fatty acid composition of phytoplankton biomass affects the CH4 and net CO2 production in anaero…
