    Juxtacortical chondromyxoid fibroma arising in an apophysis (2000)
    Springer
    Skeletal radiology 29 (2000), S. 466-469

    Notes: Abstract  We present a rare case of juxtacortical chondromyxoid fibroma arising in the lesser trochanter of the right femur which corresponds to an apophysis. Radiography showed a well-defined expansive lesion with a sclerotic margin measuring 5×3.5 cm in diameter in the lesser trochanter. On spin echo T1-weighted images, the lesion revealed low signal intensity similar to muscle. On spin echo T2-weighted images, the lesion revealed high heterogeneous signal intensity, which after gadolinium injection showed heterogeneous enhancement. The inner margin of the cortex was intact and adjacent bone marrow was of normal signal intensity. The outer margin of the lesion was also clearly defined and extension into adjacent soft tissue beyond the exophytic cortical outgrowth was not evident.

    Marchiafava-Bignami disease: serial changes in corpus callosum on MRI (1992)
    Springer
    Neuroradiology 34 (1992), S. 480-482 
    Details
    ISSN: 1432-1920
    Keywords: Degenerative disease ; Magnetic resonance imaging ; Corpus callosum ; Marchiafava-Bignami disease

    Topics: Medicine
    Notes: Summary Serial MRI findings of changes in corpus callosum lesions in two cases of Marchiafava-Bignami disease are presented. In both, MRI displayed diffuse swelling of the corpus callosum in the acute stage, thought to represent oedema and demyelination. In the chronic stage, in addition to atrophy of the corpus callosum with presumed focal necrosis, previously undescribed focal hypointensity on T2-weighted images, of unknown cause, was observed in the corpus callosum.

    Identification of the DNA damage-responsive elements of the rhp51 + gene, a recA and RAD51 homolog from the fission yeast Schizosaccharomyces pombe (1996)
    Springer
    Molecular genetics and genomics 251 (1996), S. 167-175 
    Details
    ISSN: 1617-4623
    Keywords: Key wordsSchizosaccharomyces pombe ; DNA-damage inducibility ; Damage-responsive element ; Upstream activating sequence
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The Schizosaccharomyces pombe rhp51 + gene encodes a recombinational repair protein that shares significant sequence identities with the bacterial RecA and the Saccharomyces cerevisiae 1RAD51 protein. Levels of rhp51 + mRNA increase following several types of DNA damage or inhibition of DNA synthesis. An rhp51:: ura4 fusion gene was used to identify the cis-acting promoter elements involved in regulating rhp51 + expression in response to DNA damage. Two elements, designated DRE1 and DRE2 (for damage-responsive element), match a decamer consensus URS (upstream repressing sequence) found in the promoters of many other DNA repair and metabolism genes from S. cerevisiae. However, our results show that DRE1 and DRE2 each function as a UAS (upstream activating sequence) rather than a URS and are also required for DNA-damage inducibility of the gene. A 20-bp fragment located downstream of both DRE1 and DRE2 is responsible for URS function. The DRE1 and DRE2 elements cross-competed for binding to two proteins of 45 and 59 kDa. DNase I footprint analysis suggests that DRE1 and DRE2 bind to the same DNA-binding proteins. These results suggest that the DRE-binding proteins may play an important role in the DNA-damage inducibility of rhp51 + expression.
