N-Cinnamoyltetraketide Derivatives from the Leaves of Toussaintia orientalis

2015

Seven N-cinnamoyltetraketides (1−7), including the new Ztoussaintine E (2), toussaintine F (6), and toussaintine G (7), were isolated from the methanol extract of the leaves of Toussaintia orientalis using column chromatography and HPLC. The configurations of E-toussaintine E (1) and toussaintines A (3) and D (5) are revised based on single-crystal X-ray diffraction data from racemic crystals. Both the crude methanol extract and the isolated constituents exhibit antimycobacterial activities (MIC 83.3−107.7 μM) against the H37Rv strain of Mycobacterium tuberculosis. Compounds 1, 3, 4, and 5 are cytotoxic (ED50 15.3−105.7 μM) against the MDA-MB-231 triple negative aggressive breast cancer cel…

Serum hormone concentrations and physical performance during concurrent strength and endurance training in recreational male and female endurance run…

2011

To investigate the effects of concurrent strength and endurance training on physical performance and serum hormone levels a total of 32 recreational endurance runners were trained for 18 weeks. Subjects were divided into four training groups separated by the strength training mode and gender. The groups were women’s and men’s combined maximal and explosive strength training group (WME; n=9 and MME; n=9), and women’s and men’s muscle endurance strength training group (WE; n= 8 & ME; n=8). The training was executed in three consecutive periods (I; 10 weeks, II; 4 weeks and III; 4 weeks). The endurance training in all groups was low-intensity (below lactate threshold) running throughout the wh…

Playing with delayed auditory feedback

2009

This paper presents a study where the effect of a delayed acoustic feedback is researched with 10 professional musicians performing four different pieces of piano music. The influence of a delayed auditory feedback on the performance is quantified using both MIDI information and the measurement of the movement of the upper body of the pianists. Four conditions were examined namely: a normal piano performance, a performance without acoustic feedback and two conditions with a delayed acoustic feedback of 300ms and 200ms respectively. The analysis of the MIDI data shows a significant increase in both the velocity of the keystrokes and the duration of the performance in the delayed conditions. …

Sociolinguistic upsets and people of color in social media performances

2022

Abstract Particularly since the refugee “reception crisis” in 2015, Finland has started transforming into a more diverse and multicultural society. These societal changes have also been accompanied by sociolinguistic change, as well as language ideological debates and tensions, often manifesting in explicitly racist and xenophobic bursts of upset. In this article, our focus is on social media as a space where such societal and sociolinguistic upsets are articulated and re-worked. Drawing on recent sociolinguistic and discourse analytic work on transformative and critical popular cultural practices in social media, and studies on rap and belonging, we discuss how, in a mediatized society suc…

Automatic auditory and somatosensory brain responses in relation to cognitive abilities and physical fitness in older adults

2017

AbstractIn normal ageing, structural and functional changes in the brain lead to an altered processing of sensory stimuli and to changes in cognitive functions. The link between changes in sensory processing and cognition is not well understood, but physical fitness is suggested to be beneficial for both. We recorded event-related potentials to somatosensory and auditory stimuli in a passive change detection paradigm from 81 older and 38 young women and investigated their associations with cognitive performance. In older adults also associations to physical fitness were studied. The somatosensory mismatch response was attenuated in older adults and it associated with executive functions. So…

How physical activity, fitness, and motor skills contribute to math performance: Working memory as a mediating factor

2021

Purpose The purpose of this study was to examine whether physical activity, fitness and motor skills have indirect association with math performance via cognitive outcomes and if so, through which aspects of cognition? Methods This study comprised 311 6th–9th grade adolescents (12–17y [M age=14.0y], 59% girls) from seven schools throughout Finland in 2015. Math performance was measured via a teacher-rated math achievement and the Basic Arithmetic test. Cognitive functions were measured by broad cognitive test battery. Physical activity was assessed with a self-reported questionnaire and a hip-worn accelerometer. Aerobic fitness was estimated using a maximal 20-m shuttle run test, muscular f…

Relationship between cognitive performance and mobility over the life course

2018

We studied cross-sectional, longitudinal and temporal associations between executive function and life-space mobility in old age. We assessed the association between intellectual ability in early adulthood and physical functioning in old age, and the association between early life motor development and cognitive performance in early old age. The participants of the first dataset were 157 persons aged 76-91 y who were followed up for two years as part of the Life-Space Mobility in Old Age study, and who took part in measurements on executive function (EF) implemented with the Trail Making Test and Life-Space Assessment. The second dataset comprised persons from the Helsinki Birth Cohort Stud…

Secular rise in economically valuable personality traits

2017

Although trends in many physical characteristics and cognitive capabilities of modern humans are well-documented, less is known about how personality traits have evolved over time. We analyze data from a standardized personality test administered to 79% of Finnish men born between 1962 and 1976 (n = 419,523) and find steady increases in personality traits that predict higher income in later life. The magnitudes of these trends are similar to the simultaneous increase in cognitive abilities, at 0.2-0.6 SD during the 15-y window. When anchored to earnings, the change in personality traits amounts to a 12% increase. Both personality and cognitive ability have consistent associations with famil…
