Group classification of systems of two coupled nonlinear reaction-diffusion equation with a diagonal diffusion matrix is carried out. Symmetries of diffusion systems with singular diffusion matrix and additional first order derivative terms are described.

Assuming the validity of the MDS Conjecture, the weight distribution of all MDS codes is known. Using a recently-established characterization of asymmetric quantum error-correcting codes, linear MDS codes can be used to construct asymmetric quantum MDS codes with dz ≥ dx ≥ 2 for all possible values of length n for which linear MDS codes over Fq are known to exist.

Abstract Background Central diabetes insipidus (CDI) is a rare complication of myelodysplastic syndrome (MDS). Although the cytogenetic features patients with MDS and CDI are not clear, in acute myeloid leukemia (AML) associated chromosome 7 and/or 3 anomalies. Case presentation In this report, we describe two concurrent CDI, one them, was first manifestation. One patient had monosomy on metaph...

BACKGROUND Prevalence estimates for depression vary considerably by the type of assessment instrument, and there is limited information on their overlap in population-based samples. Our aim was to compare the Patient Health Questionnaire-9 (PHQ-9) with the Composite International Diagnostic Interview (CIDI) as measures for current major depressive syndrome (MDS) in a large population-based samp...

T-cell immunoglobulin mucin-3 (Tim-3), an inhibitory immune checkpoint receptor, is highly expressed on acute myeloid leukemia cells and its ligand galectin-9 is reported to drive leukemic progression by binding with Tim-3. However, it remains unclear whether the Tim-3-galectin-9 pathway is associated with the pathophysiology of myelodysplastic syndromes (MDS). Thus, we investigated the express...

BACKGROUND Confirming diagnosis of myelodysplastic syndromes (MDS) is often challenging. Standard diagnostic methods are cytomorphology (CM) and cytogenetics. Multiparameter flow cytometry (MFC) is upcoming in MDS diagnostic work up, comparability and investigator experiences are critical. Myeloid nuclear differentiation antigen (MNDA) in myelomonocytic cells might be expressed more weakly in p...

The World Health Organization classification of acute myeloid leukemia (AML) is hierarchically structured and integrates genetics, data on patients' history, and multilineage dysplasia (MLD). The category "AML with myelodysplastic syndrome (MDS)-related changes" (AML-MRC) is separated from "AML not otherwise specified" (AML-NOS) by presence of MLD, MDS-related cytogenetics, or history of MDS or...

Myelodysplastic syndromes (MDS) are a group of disorders characterized by variable cytopenias and ineffective hematopoiesis. Hematopoietic stem cells (HSCs) and myeloid progenitors in MDS have not been extensively characterized. We transplanted purified human HSCs from MDS samples into immunodeficient mice and show that HSCs are the disease-initiating cells in MDS. We identify a recurrent loss ...

the myelodysplastic syndrome (mds) is a highly heterogenous disorder and karyotype analysis is helpful for diagnostic and prognostic estimation. deletion in long arm chromosome 6 (6q del) as a sole abnormality is a rare event in mds. this is the first case report of del (6q) as the only observed diagnostic change in iran. we also reviewed the literature of this cytogenetic lesion.
