The association of Myelodysplasia (MDS) and multiple myeloma (MM) has been usually described not only as a complication of chemotherapy but also in the absence of preceding chemotherapy or together at the time of diagnosis. Optimal therapies of a coexisting MM and MDS have not been well established up to now. We report a case of MDS diagnosed simultaneously with MM. After treatment with VTD (bo...
Maximum distance separable (MDS) matrices have applications not only in coding theory but also are of great importance in the design of block ciphers and hash functions. It is highly nontrivial to find MDS matrices which could be used in lightweight cryptography. In a crypto 2011 paper, Guo et. al. proposed a new MDS matrix Serial(1, 2, 1, 4) over F28 . This representation has a compact hardwar...
BACKGROUND The diagnosis of myelodysplastic syndrome (MDS), especially hypoplastic MDS, and MDS with low blast counts or normal karyotype may be problematic. This study characterized ID4 gene methylation in patients with MDS and aplastic anemia (AA). METHODS The methylation status of ID4 was analyzed by bisulfite sequencing polymerase chain reaction (PCR) and quantitative real-time methylatio...
The Main Conjecture on maximum distance separable (MDS) codes states that, except for some special cases, the maximum length of a q-ary linear MDS code of is q+1. This conjecture does not hold true for near maximum distance separable codes because of the existence of q-ary near-MDS elliptic codes having length bigger than q+1. An interesting related question is whether a near-MDS elliptic code ...
Decitabine (DAC) is considered to be a profound global DNA demethylation, which can induce the re-expression of silenced tumor suppressor genes. Little known about function gene FOXO1 in myelodysplastic syndromes (MDS). To address this issue, study firstly investigated differentially expressed genes (DEGs) for DAC treatment MDS cell lines, then explored role through silencing its expression bef...
گسترش شبکه های اطلاع رسانی، افزایش دسترسی مردم به کامپیوتر و جایگزینی روشهای الکترونیکی ارتباط به جای روشهای سنتی، افزایش نیاز به امن سازی اطلاعات و ارتباطات را نیز به دنبال داشته است. رمزهای قالبی از مهمترین ابزارهای رمزنگاری هستند که هدف اولیه از کاربرد آنها محرمانه نمودن داده هاست و از این رو طراحی این رمزها در دهه ی اخیر مورد توجه بیشتری قرار گرفته است. هر رمز قالبی شامل چندین مرتبه تکرار ی...
BACKGROUND The etiology of myelodysplastic syndromes (MDS) is largely unknown. Exposure to cigarette smoke (CS) is reported to be associated with MDS risk. There is inconsistent evidence that deficiency of NAD(P)H-quinone: oxidoreductase 1 (NQO1) increases the risk of MDS. Earlier we had shown that CS induces toxicity only in marginal vitamin C-deficient guinea pigs but not in vitamin C-suffici...
Myelodysplastic syndrome (MDS) is a spectrum of diseases, characterized by debilitating cytopenias and a propensity of developing acute myeloid leukemia. Comprehensive sequencing efforts have revealed a range of mutations characteristic, but not specific, of MDS. Epidemiologically, autoimmune diseases are common in patients with MDS, fueling hypotheses of common etiological mechanisms. Both inn...
Relapsing polychondritis (RP) is a rare multisystem disorder. Myelodysplastic syndrome (MDS) with erythroid hypoplasia/aplasia is a rare form of myelodysplasia. Several cases of RP associated with MDS have recently been described. However, RP associated with MDS with erythroid hypoplasia/aplasia has never been reported. There was only one case report of polymyalgia rheumatica associated with MD...
Early, low-risk International Prognostic Scoring System (IPSS) myelodysplastic syndrome (MDS) is a heterogeneous disorder where the molecular and cellular hematopoietic defects are poorly understood. To gain insight into this condition, we analyzed gene expression profiles of marrow CD34+ progenitor cells from normal-karyotype, low-blast-count MDS patients, age-matched controls, and patients wi...
