Left ventricular pressure-volume relationships during normal growth and development in the adult rat--studies in 8- and ...

Bal, M P de Vries, W B van der Leij, F R van Oosterhout, M F M Baan, J van der Wall, E E van Bel, F Steendijk, P

Published in Acta physiologica Scandinavica

Intrinsic systolic function slightly decreases from the juvenile to the middle-aged period in normal male Wistar rats. Furthermore, correction of pressure-volume indexes for body weight is not an adequate surrogate for heart weight-correction in these animals.

Enhancement of the human inspiratory pressure-flow relationship via the stretch-shortening cycle.

Sheel, A William

Published in Acta physiologica Scandinavica

Low sodium intake induces an increase in renal monoamine oxidase activity in the rat. Involvement of an angiotensin II d...

De Luca Sarobe, V Nowicki, S Carranza, A Levin, G Barontini, M Arrizurieta, E Ibarra, F R

Published in Acta physiologica Scandinavica

We have concluded that low levels of dopamine in the urine of LS rats are because of an increase in the activity of renal monoamine oxidase and that angiotensin II mediates this increase through stimulation of AT1 receptors.

The influence of endurance and resistance exercise on muscle capillarization in the elderly: a review.

Harris, B A

Published in Acta physiologica Scandinavica

Part of the difficulty in determining the nature of these relationships has been the inconsistency in research conducted regarding age groups and controlling for past and present activity patterns. Further difficulties comparing across studies arise due to the variety of methods and parameters used to sample and analyse muscle tissue. Standardizing...

Duodenal secretion in humans mediated by the EP4 receptor subtype.

Larsen, R Hansen, M B Bindslev, N

Published in Acta physiologica Scandinavica

Effects of PGE2 on secretion in the second part of human duodenum is mediated through the EP4 receptor and not through EP1, EP2, or EP3.

Muscle hypertrophy induced by the Ski protein: cyto-architecture and ultrastructure.

Bruusgaard, J C Brack, A S Hughes, S M Gundersen, K

Published in Acta physiologica Scandinavica

The reduction in specific force observed in MSV ski mice could be explained by a reduced fraction of contractile material and reduced transversal mechanical coupling. The ultrastructural abnormalities could be related to an increase in nuclear domains.

Countercurrent compartmental models describe hind limb skeletal muscle helium kinetics at resting and low blood flows in...

Doolette, D J Upton, R N Grant, C

Published in Acta physiologica Scandinavica

These results suggest a role of arterial-venous diffusion in blood : tissue helium equilibration in skeletal muscle.

Relaxant effects of beta-adrenergic agonists on porcine and human detrusor muscle.

Badawi, J K Uecelehan, H Hatzinger, M Michel, M S Haferkamp, A Bross, S

Published in Acta physiologica Scandinavica

Beta2-receptors play a main functional role in mediating relaxation of porcine detrusor. Selective beta2- and beta3-agonists similarly relax the human detrusor. Effects were smaller compared with the pig.

Melatonin-evoked potentiation of the juvenile rat tail artery neurogenic reactivity depends on degree of the change in t...

Karachentseva, O V Yartsev, V N Dvoretsky, D P Zhdanova, I V

Published in Acta physiologica Scandinavica

These data suggest that melatonin can restore an attenuated neurogenic reactivity of the juvenile rat tail artery. The effect is more pronounced with further decrease in reactivity and might be due to a change in sensitivity of the post-junctional membrane to noradrenaline.

Exercise-induced hypoxemia may be caused by an insufficient stimulating effect of exercise on the pulmonary generation o...
