Previous research on landowner willingness to retire land into the Conservation Reserve Program (CRP) is based on cross-sectional data prior to 2002. Using enrollment data on a CRP subprogram from 1998 to 2010 we find that incentives matter more for pasture than cropland, and we find that counties producing cattle respond more strongly to current incentives. We also see an idiosyncratic lack of...

We report a 10-years-old female patient with a partial trisomy 18q and monosomy 11q due to a maternal translocation. The phenotype of our proband is partially common with Jacobsen syndrome and duplication 18q but she has also some atypical anomalies such as precocious puberty, a retinal albinism and hypermetropia. Based on cytogenetics and FISH analysis, the karyotype of the proband was 46,XX,d...

We offer a nationwide analysis of the initial years of Costa Rica’s PSA program, which pioneered environmental-services payments and inspired similar initiatives. Our estimates of this program’s impact on deforestation, between 1997 and 2000, range from zero to one-fifth of 1% per year (i.e., deforestation is avoided on, at most, 2 out of every 1,000 enrolled hectares). The main explanation for...

Ewing's sarcoma is a highly aggressive pediatric tumor of bone that usually contains the characteristic chromosomal translocation t(11;22)(q24;q12). This translocation encodes the oncogenic fusion protein EWS/FLI, which acts as an aberrant transcription factor to deregulate target genes necessary for oncogenesis. One key feature of oncogenic transformation is dysregulation of cell cycle control...

The chromosomal locations of the human genes NFKBl and NFKBP, which encode two alternative DNA binding subunits of the NF-KB complex, ~105 andp49/plOO, respectively, have been determined. ~105 was assigned to 4q21.1-q24 and p49/ ~100 to chromosome 10 by Southern blot analysis of panels of human/Chinese hamster cell hybrids. The locations were confirmed by fluorescence in situ hybridization and ...

The occurrence of leukemia in twins is rare but has a crucial implication in the genetic research of leukemia. This report presents 2 pairs of monozygotic twins with precursor B-cell acute lymphoblastic leukemia. Mixed lineage leukemia (MLL)-AF4 fusion genes were found in the twin sisters. This study is the first to report on infant ALL harboring the 46,XY, -4, +10, -13, del(14)(q24), -15, +2ma...

A highly malignant human T-cell leukemia was identified by cell surface analysis as a member of the T-cell receptor (TCR) yS lineage. Cytogenetic and molecular analysis showed a novel t(8;14)(q24;qll) rearrangement involving the J,, gene segment on chromosome 14 and the distal end of chromosome 8 near the c-myc proto-oncogene locus. The yS TCR of the leukemia blasts was functionally intact and ...

Karyotypic abnormalities were studied in multiple myeloma and were correlated with clinical features. Among 115 evaluable patients, 46% had an abnormal karyotype. Trisomy 3, 5, 9, and 15 and monosomy 13 and 16 were the most common clonal abnormalities. Translocations described previously in other B cell malignancies occurred in nine patients, including four with t(8;14)(q24;q32) translocations....
