_____________________________________________________________________ We ask whether the objective of egalitarian allocation of a merit good could be achieved by making the good available at multiple outlets charging different money and time prices. Differential pricing could separate high and low wage buyers across outlets, and proportional allocation of supply could ensure that consumption is...

In this report, we describe the identification and molecular characterization of a human RAD50 homolog, hRAD50. hRAD50 was included in a collection of cDNAs which were isolated by a direct cDNA selection strategy focused on the chromosomal interval spanning 5q23 to 5q31. Alterations of the 5q23-q31 interval are frequently observed in myelodysplasia and myeloid leukemia. This strategy was thus u...

Complex chromosome rearrangements (CCRs) are structural aberrations involving three or more breakpoints on two or more chromosomes. These CCRs result in a high rate of chromosome imbalances potentially leading to subfertility and congenital abnormality. In this study, we analysed meiotic segregation in the sperm of a patient with a familial CCR 46, XY,t(1;19;13)(p31;q13.2;q31)mat included in an...

Simian virus 40 DNA sequences, integrated on human chromosome 7 in two transformed human-mouse hybrid somatic cell lines, were mapped to a specific chromosomal locus by in situ hybridization. To detect the integrated viral DNA by in situ hybridization, we increased the sensitivity of the technique by using as a probe 125I-labeled simian virus 40 cRNA (2 X 10(9) to 3 X 10(9) dpm/micrograms) prep...

A molecular cytogenetic analysis was performed on HS-RMS-2, a cell line established in this laboratory from a rare pleomorphic type of rhabdomyosarcoma. G-banding and multicolor-FISH analyses revealed that the cells have a complex chromosomal composition. Comparative genomic in situ hybridization (CGH) detected eight highly amplified regions at 1p36.1-p36.2, 1p31-p32, 1q21-q31, 8q12-q21, 8q24-q...

Basal cell carcinoma is the most common human cancer with increasing incidence reported worldwide. Despite the aberrant signaling role of the Hedgehog pathway, little is known about the genetic mechanisms underlying basal cell carcinomas. Towards a better understanding of global genetic events, we have employed the Affymetrix Mapping 10K single nucleotide polymorphism (SNP) microarray technique...

Malignant fibrous histiocytoma (MFH) of bone is a rare, highly malignant tumour. As very little is known about its genetic alterations, 26 bone MFHs were analysed by comparative genomic hybridisation (CGH). Twenty-three tumours (89%) had DNA sequence copy number changes (mean, 7.2 changes per sample). Gains were more frequent than losses (gains:losses=2.5:1). Minimal common regions for the most...
