Progressive hypoxia decouples activity and aerobic performance of skate embryos.

Conservation physiology

Di Santo V, Tran AH, Svendsen JC.
PMID: 27293746
Conserv Physiol. 2016 Jan 22;4(1):cov067. doi: 10.1093/conphys/cov067. eCollection 2016.

Although fish population size is strongly affected by survival during embryonic stages, our understanding of physiological responses to environmental stressors is based primarily on studies of post-hatch fishes. Embryonic responses to acute exposure to changes in abiotic conditions, including...

Partitioning the metabolic scope: the importance of anaerobic metabolism and implications for the oxygen- and capacity-limited thermal tolerance (OCLTT) hypothesis.

Conservation physiology

Ejbye-Ernst R, Michaelsen TY, Tirsgaard B, Wilson JM, Jensen LF, Steffensen JF, Pertoldi C, Aarestrup K, Svendsen JC.
PMID: 27293766
Conserv Physiol. 2016 Jun 03;4(1):cow019. doi: 10.1093/conphys/cow019. eCollection 2016.

Ongoing climate change is predicted to affect the distribution and abundance of aquatic ectotherms owing to increasing constraints on organismal physiology, in particular involving the metabolic scope (MS) available for performance and fitness. The oxygen- and capacity-limited thermal tolerance...

Trait Self-Compassion Reflects Emotional Flexibility Through an Association with High Vagally Mediated Heart Rate Variability.

Mindfulness

Svendsen JL, Osnes B, Binder PE, Dundas I, Visted E, Nordby H, Schanche E, Sørensen L.
PMID: 27642372
Mindfulness (N Y). 2016;7(5):1103-1113. doi: 10.1007/s12671-016-0549-1. Epub 2016 Jun 02.

Converging evidence shows a positive effect of self-compassion on self-reported well-being and mental health. However, few studies have examined the relation between self-compassion and psychophysiological measures. In the present study, we therefore examined the relation between trait self-compassion and...

The Association between Self-Reported Difficulties in Emotion Regulation and Heart Rate Variability: The Salient Role of Not Accepting Negative Emotions.

Frontiers in psychology

Visted E, Sørensen L, Osnes B, Svendsen JL, Binder PE, Schanche E.
PMID: 28337160
Front Psychol. 2017 Mar 09;8:328. doi: 10.3389/fpsyg.2017.00328. eCollection 2017.

Difficulties in emotion regulation are associated with development and maintenance of psychopathology. Typically, features of emotion regulation are assessed with self-report questionnaires. Heart rate variability (HRV) is an objective measure proposed as an index of emotional regulation capacity. A...

Intraspecific variation in aerobic and anaerobic locomotion: gilthead sea bream (Sparus aurata) and Trinidadian guppy (Poecilia reticulata) do not exhibit a trade-off between maximum sustained swimming speed and minimum cost of transport.

Frontiers in physiology

Svendsen JC, Tirsgaard B, Cordero GA, Steffensen JF.
PMID: 25741285
Front Physiol. 2015 Feb 17;6:43. doi: 10.3389/fphys.2015.00043. eCollection 2015.

Intraspecific variation and trade-off in aerobic and anaerobic traits remain poorly understood in aquatic locomotion. Using gilthead sea bream (Sparus aurata) and Trinidadian guppy (Poecilia reticulata), both axial swimmers, this study tested four hypotheses: (1) gait transition from steady...

The effect of constructing versus solving virtual patient cases on transfer of learning: a randomized trial.

Perspectives on medical education

Tolsgaard MG, Jepsen RM, Rasmussen MB, Kayser L, Fors U, Laursen LC, Svendsen JH, Ringsted C.
PMID: 26754313
Perspect Med Educ. 2016 Feb;5(1):33-8. doi: 10.1007/s40037-015-0242-4.

The purpose of this study was to explore the effect of actively constructing virtual patient (VP) cases compared with solving VP cases on knowledge gains, skills transfer and time spent on cases. Forty-five fourth-year medical students were randomized to...

Studies on Indonesian medicinal plants VI further alkaloids from Fibraurea chloroleuca.

Planta medica

Siwon J, Verpoorte R, Svendsen AB.
PMID: 17401818
Planta Med. 1981 Jan;41(1):65-8. doi: 10.1055/s-2007-971676.

From the stem and root bark of Fibraurea chloroleuca Miers the alkaloids magnoflorine, pseudocolumbamine, dehydrocorydalmine and palmatrubine were isolated and identified by their spectral data. By means of TLC the alkaloids berberine and berberrubine were found to be present...

Isolation of the secoiridoid-glucoside sweroside from Tabernaemontana psorocarpa.

Planta medica

van Beek TA, Lankhorst PP, Verpoorte R, Svendsen AB.
PMID: 17402078
Planta Med. 1982 Jan;44(1):30-1. doi: 10.1055/s-2007-971394.

The known secoiridoid glucoside sweroside (structure I) has been isolated from the leaves of Tabernaemontana psorocarpa and identified by chemical, chromatographic and spectroscopical data. Its (1)H-NMR at 360 MHz is discussed.

Determination of effective diffusion coefficients and distribution constants in polysaccharide gels with non-steady-state measurements.

Biotechnology and bioengineering

Oyaas J, Storrø I, Lysberg M, Svendsen H, Levine DW.

Biotechnol Bioeng. 1995 Aug 20;47(4):501-7. doi: 10.1002/bit.260470412.

A non-steady-state method has been used for determining the effective diffusion coefficient, D(e), and a distribution constant, K(i), of small molecules in alginate gel beads. A mathematical model based on Pick's law and includingexternal film diffusion resistance describe the...
