Cardiac myocytes and fibroblasts contain functional estrogen receptors
Autor: C, Grohé, S, Kahlert, K, Löbbert, M, Stimpel, R H, Karas, H, Vetter, L, Neyses
Publikováno v: FEBS letters. 416(1)
Gender-based differences found in cardiovascular diseases raise the possibility that estrogen may have direct effects on cardiac tissue. Therefore we investigated whether cardiac myocytes and fibroblasts express functional estrogen receptors. Immunof

Morphology and fine time structure of an early-morning electron precipitation event
Autor: R. R. Brown, I Singstad, K. Brønstad, J. Bjordal, T. Pytte, Johan Stadsnes, S. Ullaland, J.W. Münch, R. H. Karas, H. Trefall
Publikováno v: Journal of Atmospheric and Terrestrial Physics. 37:83-105
Simultaneous balloon recordings of auroral-zone X-rays from precipitating electrons, covering a range of L -values from ≈5 to ≈7.5, are presented. The precipitation event was observed in the early morning sector (from about 0200 to 0500 local mag

Large-scale auroral-zone electron precipitation event, briefly interrupted during a negative magnetic impulse
Autor: I Singstad, J. Bjordal, S. Ullaland, T. Pytte, H. Trefall, K. Brønstad, R. R. Brown, Johan Stadsnes, R. H. Karas
Publikováno v: Journal of Atmospheric and Terrestrial Physics. 36:29-42
Multiple balloon recordings of bremsstrahlung X-rays from a large scale auroral-zone electron precipitation event are presented. Additional riometer recordings show that it extended from noon, via dusk, to midnight. The X-ray observations show electr

Observations of effects from magnetospheric cusp movement during a solar proton event
Autor: P. Stauning, R. R. Brown, R. H. Karas, J. R. Barcus
Publikováno v: Journal of Geophysical Research: Space Physics. 86:7557-7565
The interplanetary magnetic field underwent a strong southward turning at the location of the ISEE 3 spacecraft, with B/sub z/ (in satellite coordinates) decreasing from +15..gamma.. to -15..gamma.. in the interval from 1540 UT to 1600 UT on August,

Publikováno v: Journal of Applied Physiology. 67:862-870
This study investigated mechanisms used by horses and steers to increase O2 uptake and delivery (VO2) from resting to maximal rates and identified the mechanisms that enable horses to achieve higher maximal rates of O2 consumption (VO2max) than steer

Magnetospheric substorms on September 14, 1968
Autor: R. H. Karas, S.-I. Akasofu, E. W. Hones, Louis J. Lanzerotti
Publikováno v: Journal of Geophysical Research. 76:6765-6780
Several moderate magnetospheric substorms on September 14, 1968, were observed by two satellites (Vela 4A and ATS 1), balloon-borne X-ray detectors, and extensive arrays of ground-based instruments in Alaska. Combined results from those observations

Publikováno v: Journal of Atmospheric and Terrestrial Physics. 35:497-511
Conjugate aspects of auroral zone electron precipitation are examined using X-ray data obtained from balloon flights launched from conjugate sites, Reykjavik, Iceland and Syowa, Antarctica, in the winter of 1969. In spite of the close conjugacy of th
