introduction: acute promyelocytic leukemia treatment revolutionized by new tretamnets. currently number of patinets who undergoe hematopoietic stem cell transplantation decrased so experience with this modality is limited. here we report our experience with stem cell transplantation in acute promyelocytic leukemia patients. design and setting: retrospective, single center methods: between year ...
فرض کنیم g یک گروه آبلی دلخواه و t زیرگروه تابدار ازg باشد. اگر a نسبت به خاصیت مجزا بودن از t ماکسیمال باشد آنگاه a یک زیرگروه t-بلند از g خوانده می شود. در این پایان نامه ابتدا نشان می دهیم که زیرگروه t-بلند l از گروه آبلی g از رتبه بی تاب یک وجود دارد بطوریکه برای هر زیرگروه t-بلند a از g داشته باشیم (type (l) ≤ type (a. در مرحله ی بعد گروههای آبلی از رتبه بی تاب یک که همه ی زیرگروههای t-بل...
An adult woman developed polymorphic post-transplant lymphoproliferative disorder (PTLD) 58 months after unrelated cord blood transplantation. She was treated successfully with chemotherapy and radiation therapy but presented with lymphadenopathy and splenomegaly 74 months after transplantation. A lymph node biopsy confirmed the diagnosis of nodular sclerosis type Hodgkin lymphoma (classical Ho...
Use of Adipose Stem Cells (ADSCs), obtained easily in a relatively less invasive manner (abdominoplasty) and characterized by flow cytometry, is a classical approach in stem cell research and clinical aspects. Other techniques such as isolation of the cells from bone marrow aspirates (1) are rather more invasive. Further, it is pertinent to point out that growth rate, differentiatio...
Asymmetric stem cell division balances maintenance of the stem cell pool and generation of diverse cell types by simultaneously allowing one daughter progeny to maintain a stem cell fate and its sibling to acquire a progenitor cell identity. A progenitor cell possesses restricted developmental potential, and defects in the regulation of progenitor cell potential can directly impinge on the main...
Arabidopsis membrane-associated acyl-CoA-binding protein ACBP1 is involved in stem cuticle formation
The membrane-anchored Arabidopsis thaliana ACYL-COA-BINDING PROTEIN1 (AtACBP1) plays important roles in embryogenesis and abiotic stress responses, and interacts with long-chain (LC) acyl-CoA esters. Here, AtACBP1 function in stem cuticle formation was investigated. Transgenic Arabidopsis transformed with an AtACBP1pro::GUS construct revealed β-glucuronidase (GUS) expression on the stem (but no...
Kissing interactions in RNA are formed when bases between two hairpin loops pair. Intra- and intermolecular kissing interactions are important in forming the tertiary or quaternary structure of many RNAs. Self-cleavage of the wild-type Varkud satellite (VS) ribozyme requires a kissing interaction between the hairpin loops of stem-loops I and V. In addition, self-cleavage requires a rearrangemen...
Introduction: The aim of this study was evaluate the ability of notochord to induce neural induction and/or differentiation of mouse embryonic stem cell to neuron and motor neuron, respectively. Methods: In order to produce embryoid bodies, ES cells line Royan B1 were grown in suspension in the absence of LIF for 4 days. EBs were divided into 4 groups. EBs in group 1 & 2 were further cultur...
Abstract Background: Adipose tissue is being used word-wide as a suitable adult stem cell source the aim of this study was to examine the possibility of using different enzymes to isolate the human mesenchymal stem cells from adipose tissue. Methods: Adipose tissues which were obtained from liposuction surgery were transferred to the laboratory under sterile conditions. All samples obtained...
