A patient with Down's syndrome was found to have 47,XX,+18/47,XX,+21 mosaicism. Chromosome 18 trisomy was found only in 18% of lymphocytes and not in skin fibroblasts. A likely interpretation is double nondisjunction in a single lymphocyte precursor of a trisomy 21 embryo. A brief review of other cases of mitotic multiple nondisjunction and double aneuploid mosiacism is presented.
AIMS A pilot feasibility study to investigate the local immune response in patients with non-gonococcal urethritis (NGU). METHODS Urethral lymphocytes were extracted from first void urine (FVU) of patients with non-gonococcal urethritis and gonorrhoea using magnetic beads coated with antibody against either the pan-T cell marker CD2 or to CD4. The CD2+ and CD4+ lymphocyte content of FVU were ...
BACKGROUND AND OBJECTIVES T-cell-rich B-cell lymphoma is a rare variant of diffuse large B-cell lymphoma. It shows morphologic, phenotypic and molecular similarities to lymphocyte predominant Hodgkin's disease, and in consequence the two diseases may sometimes be difficult to distinguish. In this paper, we have evaluated the usefulness of the pan-leukocyte marker LSP1 and the transcription fact...
An acoustic negative bulk modulus metamaterial based on the concept of expansion chambers is proposed. It is shown that addition of a neck region to an ordinary expansion chamber improves its transmission loss characteristics at low frequencies and the resulting structure displays a negative bulk modulus behavior. Additionally, membrane based metamaterials are analyzed. Using FEM, the negative ...
BACKGROUND The sensitivity of rapid influenza diagnostic test (RIDT) of children with influenza-like illness (ILI) remains low. OBJECTIVE We compare the parameters between pandemic A(H1N1) 2009 influenza with negative RIDT and ILI not H1N1 for improving the low sensitivity of RIDT for children with ILI. METHODS In a cohort of consecutive laboratory-confirmed H1N1 influenza, we identified 15...
Some chromosomal translocations in acute leukemias involve the fusion of the trithorax-related protein Mll (also called HRX, All1, Htrx,) with a variety of heterologous proteins. In acute lymphoblastic leukemia associated with the t(4;11)(q21;q23) translocation, the 4q21 gene that fuses with Mll is AF4. To gain insight into the potential role of AF4 in leukemogenesis and development, this gene ...
Donor-lymphocyte infusion (DLI) before transplantation can lead to specific tolerance to allografts in mice, nonhuman primates, and humans. We and others have demonstrated a role for regulatory T cells in DLI-induced, donor-specific transplantation tolerance, but it is not known how regulatory T cells are activated and where they execute their function. In this study, we observed, in both trans...
