No effects of DC and 60-Hz AC magnetic fields on the first mitosis of two species of sea urchin embryos

Autor: C, Pagnac, A M, Genevière, J M, Moreau, A, Picard, J, Joussot-Dubien, B, Veyret

Publikováno v: Bioelectromagnetics. 19(8)

The early divisions of sea urchin eggs was used as a model to study the effects of static and of 60 Hz sinusoidal magnetic fields. Two species were used (Sphaerechinus granularis and Paracentrotus lividus). Eggs were fertilized and exposed in two sep

Quantitative trace analysis of polycyclic aromatic hydrocarbons by high-performance liquid chromatography and low-temperature fluorimetry in shpolskii matrices at 4.2°K

Autor: G. Vion, J. Joussot-Dubien, J.M. Colin, M. Lamotte

Publikováno v: Journal of Chromatography A. 204:135-142

A scheme of analysis for polycyclic aromatic hydrocarbons (PAHs) in medicinal white oils was developed; this was made possible by carrying out three initial chromatographic stages to isolate the PAHs and following this by a combination of high-perfor

Publikováno v: Canadian Journal of Chemistry. 53:2386-2393

A number of polycyclic aromatic thiones have been prepared from the corresponding ketones. Several of the thiones in which there is a free peri position cyclize, on excitation in the π* ← n band, to give thiophene derivatives. The structures of th
