EXTRA VIRGIN OLIVE OIL IMPROVES LEARNING AND MEMORY IN SAMP8 MICE
2011
Abstract. Polyphenols are potent antioxidants found in extra virgin olive oil (EVOO); antioxidants have been shown to reverse age- and disease-related learning and memory deficits. We examined the effects of EVOO on learning and memory in SAMP8 mice, an age-related learning/memory impairment model associated with increased amyloid- protein and brain oxidative damage. We administered EVOO, coconut oil, or butter to 11 month old SAMP8 mice for 6 weeks. Mice were tested in T-maze foot shock avoidance and one-trial novel object recognition with a 24 h delay. Mice which received EVOO had improved acquisition in the T-maze and spent more time with the novel object in one-trial novel object recogni…
Different sample treatment approaches for the analysis of T-2 and HT-2 toxins from oats-based media.
2010
A LC-DAD method is proposed for the determination of the T-2 and HT-2 toxins in cultures of Fusarium langsethiae in oat-based and other in vitro media. Test media consisted of freshly prepared milled oats to which T-2 and HT-2 toxin stock solutions were added. Different mixtures of extraction solvent (acetonitrile:water and methanol water), extraction times (30', 60' or 90') and drying methods were investigated. Results showed that extraction with methanol: water (80:20, v/v) for 90 min, drying with N-2 and subsequent analysis by LC-DAD was the fastest and most user friendly method for detecting HT-2 and T-2 toxins production by F. langsethiae strains grown on oat-based media at levels of 0…
Transfers of small analytes in a multiphasic stirred fruit yoghurt model
2007
International audience; The transfer of small analytes in a multiphasic stirred fruit yoghurt model, made of a pectin gel aimed to mimic fruit pieces and of a dairy gel done with milk acidified by glucono-δ-lactone hydrolysis, have been studied. The concentration gradients between the pectin gel and the dairy gel were the driving force for the migration of small analytes (i.e. water, protons and colorants). Water migrated from the dairy to the pectin gel, causing modifications in the water content of both gels and an equilibration of their water activity at 0.938±0.003. Inversely, protons migrated from the pectin to the dairy gel. These changes in composition of both gels being likely to ha…
Antibacterial effect of a new haemostatic agent on oral microorganisms
2011
Objective: The purpose of this study was to determine the antibacterial effect of a newly developed haemostatic agent Ankaferd Blood Stopper® (ABS) and Ferric Sulphate (FS) on various oral microorganisms. Study design: Bacterial strains were freshly incubated in their specific broth media. For each of the strains, 3 wells per each agent, with a 5 mm diameter were made under aseptic conditions in the specific agar media. Then they were filled with a test agents or 0.2% chlorhexidine digluconate (CHX) (control group). After 24h and 48h incubation periods, inhibition zones were measured. Results: ABS showed antibacterial effect on all test microorganisms except Lactobacillus acidophilus and La…
The difference in risk of chronic pulmonary disease morbidity and mortality between elite athletes and ordinary men in Finland
2020
Introduction: The impact of a history of competitive sports on later smoking behavior and occurrence of chronic pulmonary diseases is poorly known. We investigated how a history of elite level sports predicted later pulmonary disease morbidity and mortality. Methods: Chronic pulmonary disease incidence were assessed from national hospital and cause-of-death registers from 1970 to 2015 among Finnish male former elite athletes (n=2078) and matched controls (n=1453) alive in 1970 (mean age 45.0 years). Hazard ratios (HRs) were calculated by Cox proportional hazards model. In 1985, cohort members reported on their smoking habits, engagement in physical activity/sports and physician-diagnosed ch…
"Se on semmosta arkipäivää" : liikunta esiopetusryhmän kuvaamana ja toteuttamana
2012
Tiivistelmä. Saastamoinen, Anna & Sirniö, Sanna. 2012. ”SE ON SEMMOSTA ARKIPÄIVÄÄ”. Liikunta esiopetusryhmän kuvaamana ja toteuttamana. Varhaiskasvatustieteen pro gradu -tutkielma. Kasvatustieteiden laitos. Jyväskylän yliopisto. 120 sivua + liitteet. Tämän tutkimuksen lähtökohtana oli liikunnan vankka asema suomalaisessa yhteiskunnassa, ja siihen latautuvat positiiviset merkitykset. Yhteiskunnassamme puhutaan nykyään paljon lasten liikunnan vähentymisestä, liikuntamahdollisuuksien muuttumisesta sekä ohjatun liikunnan lisääntymisestä. Liikunta on käsitteenä monimuotoinen, ja sillä on sekä itseisarvoisia että välineellisiä tehtäviä. Esiopetuksessa toteutettavalla liikuntakasvatuksella on merk…
Multixenobiotic resistance efflux activity in Daphnia magna and Lumbriculus variegatus
2015
Multixenobiotic resistance is a phenomenon in which ATP-binding cassette (ABC) family proteins transfer harmful compounds out of cells. Daphnia magna and Lumbriculus variegatus are model species in aquatic ecotoxicology, but the presence and activity of ABC proteins have not been well described in these species. The aim of this work was to study the presence, activity, and inhibition of ABC transport proteins in D. magna and L. variegatus. The presence of abcb1 and abcc transcripts in 8–9-day-old D. magna was investigated by qRT-PCR. The activity of MXR in D. magna and L. variegatus was explored by influx of the fluorescent ABC protein substrates rhodamine B and calcein-AM, with and without…
Investigation of fungicidal activity of 3-piperazine-bis(benzoxaborole) and its boronic acid analogue
2014
3-Piperazine-bis(benzoxaborole) and its bis(phenylboronic acid) analogue were investigated in terms of their fungicidal activity. The study was carried out against five filamentous fungi: Aspergillus terreus, Fusarium dimerum, Fusarium solani, Penicillium ochrochloron and Aspergillus niger. 3-Piperazine-bis(benzoxaborole) revealed higher inhibitory activity towards the examined strains than standard antibiotic (amphotericin B), whereas bis(phenylboronic acid) proved to be inactive. The study unequivocally showed that the presence of the heterocyclic benzoxaborole system is essential for antifungal action of the examined compounds.

Relationship between physical activity, fitness and brain morphology in youth
2017
Yhä useammat tutkimukset ovat havainneet yhteyden fyysisen aktiivisuuden, fyysisen kunnon ja kognitiivisten kykyjen välillä, mutta tätä yhteyttä selittävät tekijät ja siihen liittyvät muutokset aivojen rakenteissa ovat vielä varsin epäselviä. Tässä tutkimuksessa oli tarkoitus selvittää, onko fyysisellä aktiivisuudella tai fyysisellä kunnolla yhteyttä aivojen rakenteeseen nuorilla. Tutkimuksen koehenkilöt olivat 35 suomalaista nuorta (14.14 ±0.71 vuotta, 23 tyttöä & 12 poikaa), otanta laajemmasta AFIS (Active, Fit and Smart) -tutkimusprojektista. Tutkimuksessa mitattiin fyysistä aktiivisuutta objektiivisilla kiihtyvyysanturimittareilla, fyysistä kuntoa lasten ja nuorten mittaamiseen tarkoite…
