Two different fluorescence stains, green: 5-hexadecanoylaminofluorescein, and red: BODIPY(R) 665/676 [(E,E)-3, 5-bis-(4-phenyl-1,3-butadienyl)-4,4-difluoro-4-bora-3a, 4a-diaza-s-indacene, produced good results regarding the demonstration of glycolipids, free fatty acids and triglycerides in mammalian skin material that had been embedded in a water miscible(More)
In adult goldfish, electrophysiological studies have shown that the retinotectal projection reorganizes, following removal of half of the tectum, to form a complete but compressed projection over the remaining half tectum. As a result, each fiber terminates more rostrally than normal. Electron microscopic studies suggest a competition between retinal fibers(More)
The potential hazard of chemicals on aquatic communities are generally evaluated by standardised single-species bioassays. Safety assessment is based on results gained from organisms adapted to lentic systems and biological interactions in ecosystems are neglected. While lotic communities are often at first in contact with chemicals, it is astonishing that(More)
We have recently developed an in vitro assay for human tumor stem cells that permits cloning of human ovarian adenocarcinoma cells in soft agar. Tumor colonies grew from both effusions and biopsies from 85% of 31 ovarian cancer patients. The cloning efficiency did not vary with the histology of the tumor. Growth was induced with medium conditioned by the(More)
This is a toy example to illustrate some of the techniques of fusion and transfer as described in Gorenstein’s text Finite Groups. Finite groups with a unique subgroup of order p (p an odd prime) are classified in terms of a cyclic p′-extension of relatively simple combinatorial data. This note is intended to address a slightly misstated exercise in(More)
