Ultra early posttransplantation lymphoproliferative disorder (PTLD) is a rare and fatal complication after hematopoietic stem cell transplantation (HSCT). Here we report, by lymph node (LN) flowcytometry, that we early recognized ultra early PTLD after an HLA-matched sibling allo-HSCT followed by a successful treatment with anti-CD20 antibody (rituximab) in a patient in progress disease for ang...

BACKGROUND Recent publications about differentiation of stem cells to germ cells have motivated researchers to make new approaches to infertility. In vitro production of germ cells improves understanding differentiation process of male and female germ cells. Due to the problem of using embryonic stem cells (ESC), it's necessary the mentioned cells be replaced with some adult multi-potent stem c...

black seed (nigella sativa) is considered as a biological response modifier. thymoquinone (tq) is the bioactive and the most abundant constituent of the volatile oil of this seed which has been shown to possess anti-inflammatory, antioxidant and anti-neoplastic effects. in this study, the effect of tq on hepg2 cell line was investigated in an attempt to identify its potential mechanism of actio...

Beta thalassemia is a common monogenic disorder caused by partial or complete reduction of beta globin chains synthesis. In recent years allogeneic bone marrow transplantation (BMT) has been considered to be the successful cure for patients with major, however this restricted due limited number HLA-matched donors. Therefore, molecular approaches including gene therapy direct normal transmission...

background: lactoferrin is a glycoprotein with a molecular weight of 80 kda, as a member of the transferring family. in recent investigations the important biological properties such as anti microbial, antiviral and anticancer activity of lactoferrin were studied. in the present study, the effect of antitumor induced by lactoferin was evaluated on stomach cancer cell ags. materials and methods:...

the human major histocompatibility complex (mhc) plays a crucial role in transplantation, transfusion, paternity test and assessment of susceptibility to some diseases associated with hla-b27. three of the most fashionable methods for determination of hla antigens in clinical and research laboratories are microlymphocytotoxicity (mlct), flowcytometry and polymerase chain reaction (pcr). the pur...
