Discovery of a new branch of the Taurid meteoroid stream as a real source of potentially hazardous bodies
Taurid meteor shower produces prolonged but usually low activity every October and November. In some years, however, the activity is significantly enhanced. Previous studies based on long-termExpand

Partial characterization of the genome of the ‘endosymbiotic’ cyanelles from cyanophora paradoxa
Cyanophoru paradoxa, a flagellate of uncertain taxonomic position, is capable of growing photoautotrophically and its cyanelles are generally accepted to be endosymbiotic blue-green algae [ 11. InExpand

Evaluation of an indirect immunofluorescence assay for confirmation of human immunodeficiency virus type 1 antibody in U.S. blood donor sera.
An indirect immunofluorescence assay (IFA) was evaluated as a confirmatory test for antibody to human immunodeficiency virus type 1 in U.S. blood donor sera previously found to be repeatedly reactiveExpand

The subcellular localization of DNA components from Cyanophora paradoxa, a flagellate containing endosymbiotic cyanelles.
Cyanophora paradoxa, a unicellular flagellate, contains cyanelles which are supposed to be cyanobacterial origin. DNA was isolated from subcellular fractions and separated according to densityExpand

Cyanelle DNA from Cyanophora paradoxa
SummaryCyanelles which have been found in few eukaryotic organisms are photosynthetically active organelles which strikingly resemble cyanobacteria. The complexity of the cyanelle genome inExpand

The central part of the cyanelle rDNA unit of Cyanophora paradoxa: Sequence comparison with chloroplasts and cyanobacteria
The 287-bp spacer and the flanking 3′-end of the 16S- and 5′-end of the 23S-rRNA genes of the cyanelles from Cyanophora paradoxa have been sequenced and compared with the corresponding regions ofExpand

Comparison of the cyanelle DNA from two different strains of Cyanophora paradoxa
SummaryThe cyanelle DNA from two different strains of Cyanophora paradoxa (strain LB555UTEX and strain 1555) was investigated.The cyanelle DNA from both strains showed a buoyant density in neutralExpand
