Loss of heterozygosity (LOH) of chromosomal regions bearing tumor suppressors is a key event in the evolution of epithelial and mesenchymal tumors. Identification of these regions usually relies on genotyping tumor and counterpart normal DNA and noting regions where heterozygous alleles in the normal DNA become homozygous in the tumor. However, paired(More)
Minor histocompatibility antigens (mHAs) are known targets of donor T cells after allogeneic hematopoietic stem cell transplantation (HSCT). In contrast, B-cell responses to mHAs have not been extensively characterized and the clinical significance of antibodies to mHAs is unknown. We tested 121 patients who underwent HSCT and 134 healthy donors for(More)
A major end point of nonmyeloablative hematopoietic stem cell transplantation is the attainment of either mixed chimerism or full donor hematopoiesis. Because the majority of human genetic disparity is generated by single nucleotide polymorphisms (SNPs), direct measurement of SNPs should provide a robust tool for the detection and quantitation of chimerism.(More)
We hypothesized that prenatal cocaine exposure results in less optimal infant behavior and more impaired maternal-infant interaction in healthy term infants. Infants were evaluated with the Neonatal Behavioral Assessment Scale (NBAS) at days 1-3 and 11-30 of age, and mother-infant pairs with the Nursing Child Assessment of Feeding Scale (NCAFS) at 7-16(More)
Bing-Neel syndrome (BNS) is defined as intracranial involvement of Waldenström macroglobulinemia (WM). Few cases of orbital involvement have been reported. A 51-year-old man with a history of WM developed bilateral orbitopathy and optic neuropathy. Orbital biopsy, cerebrospinal fluid studies, and neuroimaging confirmed the diagnosis of BNS involving the(More)
PURPOSE Chronic lymphocytic leukemia (CLL) cells treated with dasatinib in vitro undergo apoptosis via inhibition of Lyn kinase. Thus, in this study we tested the activity of dasatinib in patients with relapsed CLL. EXPERIMENTAL DESIGN Patients were eligible for this phase II trial if they had documented CLL/SLL and had failed at least 1 prior therapy(More)
Few large, international series of enteropathy-associated T-cell lymphoma (EATL) have been reported. We studied a cohort of 62 patients with EATL among 1153 patients with peripheral T-cell or natural killer (NK)-cell lymphoma from 22 centers worldwide. The diagnosis was made by a consensus panel of 4 expert hematopathologists using World Health Organization(More)
BACKGROUND Burkitt's lymphoma (BL) is a highly aggressive B-cell non-Hodgkin's lymphoma (NHL) that may be cured with intensive chemotherapy. The addition of the CD20-directed monoclonal antibody rituximab to CODOX-M/IVAC (cyclophosphamide, vincristine, doxorubicin, and high-dose methotrexate, alternating with ifosfamide, etoposide, and cytarabine) has not(More)
Recovery was produced by a homogeneous flash of light (M2). With M2 absent, correct letter report was a U-shaped curve when plotted against the interval separating the onset of a letter target and the onset of a patterned masking stimulus (M1). With the homogeneous flash of light ed to the stimulus sequence (target + M1 + M2), recovery occurred for all the(More)
OBJECTIVE Extracting medical knowledge from electronic medical records requires automated approaches to combat scalability limitations and selection biases. However, existing machine learning approaches are often regarded by clinicians as black boxes. Moreover, training data for these automated approaches at often sparsely annotated at best.
