Penicillium auxotrophic mutants can be detected by suing xanthene dyesExperientia - Tập 43 - Trang 206-207 - 1987
E. Alonso, S. Ferrer, F. Uruburu, E. Vicente
Auxotrophic mutants ofPenicillium spp. have been directly isolated after mutagenic treatment from agar plates containing Xanthene dyes. They grow as characteristic small colored colonies. Some strains were tested and they showed a differential response depending on the Xanthene dye used.
Nematicidal activity of dimethyl 1-dodecanephosphonateExperientia - Tập 39 - Trang 81-83 - 1983
J. Feldmesser, J. Kochansky, W. E. Robbins
Dimethyl 1-dodecanephosphonate has been shown in laboratory bioassays and greenhouse tests to be highly active against 2 species of nematodes. Other phosphonate esters showed little or no activity.
The effects of nerve growth factor antiserum on ambystomaExperientia - Tập 26 - Trang 155-156 - 1970
Judith S. Weis
Des injections d'un sérum spécifique contre le facteur de croissance nerveuse (anti-NGF) provoquent une réduction de la taille des ganglions rachidiens de la salamandreAmbystoma par suite de la réduction de la masse cellulaire du ganglion. Il y a aussi un plus grand nombre de «petites» cellules (d'un diamètre nucléaire de moins de 6,25 μ) dans les ganglions des animaux utilisés.
4-HydroxyurazoleExperientia - Tập 28 - Trang 10-10 - 1972
Kwang-Yuen Zee-Cheng, C. C. Cheng
Durch Hydroxylaminolyse von 1,2-bis (äthoxycarbonyl)hydrazin wurde Natriumsalz von 1-Äthoxycarbonyl-2-hydroxylaminocarbonylhydrazin hergestellt und mit wässeriger Salzsäure auf pH<1 in 4-Hydroxyurazol (N-Hydroxybicarbamimid) synthetisiert.
Enzyme localization in proteins separated by paper electrophoresis in human seminal plasmaExperientia - Tập 18 - Trang 552-552 - 1962
H. Povoa
Les transaminases α-glutamo-oxaloacétique (GOT) et glutamo-pyruvique (GPT) ont été déterminées dans les protéines du liquide spermatique de l'homme après séparation par électrophorèse sur papier. L'amylase se trouve dans toutes les fractions, mais la GOT et la GPT sont localisées respectivement dans la globuline α-2 et l'albumine.
Der Vitaminbedarf des amerikanischen ReismehlkäfersTribolium confusum DuvalExperientia - Tập 1 - Trang 275-276 - 1945
C. A. Grob, T. Reichstein, H. Rosenthal
As previously reported the larvae ofTribolium confusum require two unknown factors obtainable from yeast apart from various vitamines of the B-group for normal growth. One of these possesses acidic properties. This factor could be fully replaced by a folic acid preparation of potency 4000 kindly placed at our disposal by Prof.R. J. Williams. This may be regarded as a possibility but not as a proof...... hiện toàn bộ
Photoreceptors in the pineal of lower vertebrates: Functional aspectsExperientia - Tập 45 - Trang 909-913 - 1989
J. Falcón, J. -P. Collin
The pineal of lower vertebrates characteristically contains true and modified photoreceptors with functional und structural homologies to retinal photoreceptors. Afferent nerves convey photic information from the pineal to sensory areas of the brain stem. Light also influences synthetic activity within the organ, controlling the rhythm in melatonin production which is generated endogenously. The m...... hiện toàn bộ
