Motivation Despite the potential usefulness, the association analysis of gene expression with interval times of two events has been hampered because the occurrence of events can be censored and the conventional survival analysis is not suitable to handle two censored events. However, the recent advances of multivariate survival analysis considering multiple censored events together provide an u...

The frequency of acute lymphoblastic leukemia (ALL) patients expressing myeloid antigens on their ALL cells varies between 5 and 36% in several different studies. The clinical relevance of myeloid antigen expression in childhood ALL is controversial. In Indonesian patients, no data were present. Therefore, in Yogyakarta, Indonesia, we analyzed 239 ALL patients who were immunophenotyped includin...

Although the rate of blastocysts implantation of embryos is higher than previous stages but their survival rate is lower than them, which could be attributed to the completely filled blastocoel cavity with liquid and increased possibility of the formation of ice crystals. This liquid could prevent the penetration of cryoprotecting materials into the embryos. In this study, we reduced the volume...

How did I get to become a cell biologist? Or, more generally, why do things happen the way they do? The answer provided by the philosopher Democritus and later adopted by Jacques Monod is "everything existing in the universe is the fruit of chance and necessity." While I read Monod's book Chance and Necessity as an undergraduate student, little did I appreciate the accuracy of this citation and...

background: heat shock proteins (hsps) are a family of proteins that are known to play a significant role in the repair of denatured proteins in the cell. it seems that cytoprotective properties of hsps may help in malignant progression by facilitating tumor cell growth and survival. the purpose of this study is to evaluate hsp27 and hsp70 expression in various histopathological grades of squam...

Background: Mesenchymal stem cells (MSCs) are ideal cells for cell and gene therapy. However, the low survival of MSCs after transplantation has limited their applications. We aimed to evaluate the expression of cytoprotective genes including NQO1, TXNRD1, HO-1, GCLC following the over expression of Nrf2 in umbilical cord-derived MSCs (UC-MSCs). Methods: 3-5 passages of UC-MSCs were cultured. ...

regulation of normal cell growth and turnover is balanced between cell pro¬liferation, cell differentiation and apoptosis. a disruption of this balance is thought to be an important event leading to carcinogenesis .one of the effector molecules in apoptosis is fas antigen . cross-linking of fas by its ligand (fas l) or agonistic anti fas antibodies induces apoptosis of cells expressing fas on t...
