Studies of the Cortinarius saniosus (Fr.: Fr.) Fr. complex and a new closely related species, C. aureovelatus (Basidiomycota, Agaricales)

The HST view of the FR I / FR II dichotomy ⋆

In order to explore how the FR I / FR II dichotomy is related to the nuclear properties of radio galaxies, we studied a complete sample of 26 nearby FR II radio galaxies using Hubble Space Telescope (HST) images and compared them with a sample of FR I previously analyzed. FR I nuclei lie in the radio-optical luminosity plane along a tight linear correlation, which argues for a common synchrotro...

Antibiotics from basidiomycetes. X. Scorodonin, a new antibacterial and antifungal metabolite from Marasmius scorodonius (Fr.) Fr.

Scorodonin (1), a novel biologically active metabolite, was isolated from submerged cultures of the mushroom Marasmius scorodonius (FR.) FR. Its structure has been determined by chemical and physical methods. The antibiotic inhibits the growth of bacteria, yeasts, and filamentous fungi. In cells of the ascitic form of EHRLICH carcinoma the incorporation of thymidine and uridine into DNA and RNA...

FR 305.pmd

The quail raising in Brazil has increased through the last years and the incubation procedures are important to maintenance and improvement of quail egg production. To obtain a sufficient number of eggs to fill an incubator, eggs are usually accumulated in storage over a period from 1 day up to 3 weeks before incubation. The objective of this research was to verify the effect of egg storage on ...
