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…

Long-Term Data Reveal the Associations of the Egg Quality With Abiotic Factors and Female Traits in the Baltic Herring Under Variable Environmental C…

2021

In fish, the lipid resources of the female form a link between the environment and progeny, contributing to the contents of the egg yolk. Variation of the environmental conditions is therefore expected to affect the egg quality via maternal pathways, reflecting the female’s response to the environmental factors before spawning. We investigated the content of lipids and thyroid hormones in the ovary and eggs of the Baltic herring during 1988–2019, when salinity of the Baltic Sea first declined and then stabilized to a lower level, and winters varied between severe and mild. The total lipid resources of spawning females decreased by 40–50% during the study, and the ovarian lipid concentration…

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…

High Lipid Content of Prey Fish and n−3 PUFA Peroxidation Impair the Thiamine Status of Feeding-Migrating Atlantic Salmon (Salmo salar) and Is Reflec…

2022

Signs of impaired thiamine (vitamin B1) status in feeding-migrating Atlantic salmon (Salmo salar) were studied in three Baltic Sea areas, which differ in the proportion and nutritional composition of prey fish sprat (Sprattus sprattus) and herring (Clupea harengus). The concentration of n−3 polyunsaturated fatty acids (n−3 PUFAs) increased in salmon with dietary lipids and n−3 PUFAs, and the hepatic peroxidation product malondialdehyde (MDA) concentration increased exponentially with increasing n−3 PUFA and docosahexaenoic acid (DHA, 22:6n−3) concentration, whereas hepatic total thiamine concentration, a sensitive indicator of thiamine status, decreased with th…

Aerobic exercise training and gut microbiome-associated metabolic shifts in women with overweight : a multi-omic study

2023

Physical activity is essential in weight management, improves overall health, and mitigates obesity-related risk markers. Besides inducing changes in systemic metabolism, habitual exercise may improve gut’s microbial diversity and increase the abundance of beneficial taxa in a correlated fashion. Since there is a lack of integrative omics studies on exercise and overweight populations, we studied the metabolomes and gut microbiota associated with programmed exercise in obese individuals. We measured the serum and fecal metabolites of 17 adult women with overweight during a 6-week endurance exercise program. Further, we integrated the exercise-responsive metabolites with variations in the gu…

Resistance Training Induces Antiatherogenic Effects on Metabolomic Pathways

2019

Introduction: Arising evidence suggests that resistance training has the potential to induce beneficial modulation of biomarker profile. To date, however, only immediate responses to resistance training have been investigated using high-throughput metabolomics whereas the effects of chronic resistance training on biomarker profile have not been studied in detail. Methods: A total of 86 recreationally active healthy men without previous systematic resistance training background were allocated into i) a resistance training (RT) group (n=68, age 33 ± 7 years, body mass index (BMI) 28 ± 3 kg/m2 ) and ii) a non-RT group (n=18, age 31 ± 4 years, BMI 27 ± 3 kg/m2 ). Blood samples were collected at…

Intramyocellular topography of lipid droplets and OXPAT in obesity and type II diabetes

2010

Nowadays in the westernized world, high caloric diet and sedentarism are driving populations to accumulate ectopic fat, especially in skeletal muscle. Such is associated with the development of insulin resistance (IR) related metabolic diseases, as type II diabetes (T2D) and obesity (OB). Like IR individuals, athletes also show high intramyocellular lipids (IMCL) contents, denoting qualitative rather than quantitative differences between insulin sensitive (IS) and IR individuals IMCL. PAT proteins and OXPAT specifically, are among the main regulators of lipid droplets (LDs) in skeletal muscle. We hypothesized that different IS profiles are distinguishable through LD and OXPAT localization a…

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…
