Evening melatonin in January after changes in hours of habitual exercise during fall among youths living in the subarctic.
(Journal article; Tidsskriftartikkel; Peer reviewed, 1994)
Secretion of the hormone melatonin shows a circadian rhythm and is inhibited by
light. Light therapy with phase shifting of the melatonin rhythm has been used
as treatment of sleeping problems and seasonal affective disorders (SAD). Exercise
has also been shown to suppress the melatonin secretion. In order to investigate
the effect of increased level of habitual physical activity upon ...
The TNF Receptors p55 and p75 Mediate Chemotaxis of PMN Induced by TNFα and a TNFα 36–62 Peptide
(Journal article; Tidsskriftartikkel; Peer reviewed, 1994)
The present study was performed to examine whether residues 36–62 of TNFα contain the chemotactic domain of TNFα, and whether the p55 and p75 TNF receptors are involved in TNFα induced chemotaxis. The chemotactic effect of TNFα on PMN was inhibited by the mAbs Hrt-7b and Utr-1, against the p55 and p75 TNF receptors, respectively. Both receptors may therefore be required for mediating the chemotactic ...
Endothelin-1 Stimulates Monocytes in vitro to Release Chemotactic Activity Identified as Interleukin-8 and Monocyte Chemotactic Protein-1
(Journal article; Tidsskriftartikkel; Peer reviewed, 1994)
In the present study we examined whether endothelin-1 stimulation of human monocytes causes release of chemotactic factors. It was found that monocytes released neutrophil- and monocyte-chemotactic activity in a dose- and time-dependent manner in response to ET-1. ET-1 did not show any chemotactic activity by itself. NCA was detected in monocyte supernatants in response to ET-1 (0.01–100 nM) after ...
