| recurrent insertion of 5'-terminal nucleotides and loss of the branchpoint motif in lineages of group ii introns inserted in mitochondrial preribosomal rnas. | a survey of sequence databases revealed 10 instances of subgroup iib1 mitochondrial ribosomal introns with 1 to 33 additional nucleotides inserted between the 5' exon and the consensus sequence at the intron 5' end. these 10 introns depart further from the iib1 consensus in their predicted domain vi structure: in contrast to its basal helix and distal gnra terminal loop, the middle part of domain vi is highly variable and lacks the bulging a that serves as the branchpoint in lariat formation. in ... | 2011 | 21613530 |
| effects of pycnoporellus fulgens (fr.) donk crude extract on candida glabrata ultrastructure. | among antifungal products of natural origin, pycnoporellus fulgens (fr) donk, is active against pathogenic yeasts. our study was carried out to observe the ultrastructural modifications produced by p. fulgens crude extract on candida glabrata. yeasts were submitted to different concentrations (50, 100, 200, 400 micrograms ml-1) for 72 h under constant stirring at 35 degrees c. transmission electron microscopy revealed that the extract acted on the cell envelope (cell wall and plasmalemma). cell ... | 1999 | 10424096 |
| in vitro antifungal activity of polyporaceae against yeasts and dermatophytes. | the antifungal activity of 38 polyporaceae sensu lato against yeasts and dermatophytes was tested in vitro by the agar dilution method. strains were typed organisms and clinical isolates. in this first report, pycnoporellus fulgens (fr.) donk was found to be the most active species against pathological fungi and showed broad-spectrum antifungal activity against yeasts (candida albicans, candida glabrata) and dermatophytes (trichophyton mentagrophytes, trichophyton rubrum, microsporum canis, micr ... | 1995 | 8559195 |
| [rare and threathened polypores in the ecosystem of changbaishan nature reserve of northeastern china]. | in last 10 years, extensive field inventories were carried out to investigate polypore species, the major wood-decaying fungi in the changbaishan nature reserve of northeastern china. the following 27 species were treated as rare or threathened species: amylocystis lapponica (romell) singer, anomoporia albolutescens (romell) pouzar, anomoporia bombycina (fr.) pouzar, anomoporia vesiculosa y.c. dai & niemelä, antrodia carbonica (overh.) ryvarden & gilb., antrodia crassa (p. karst.) ryvarden, antr ... | 2003 | 12974018 |
