co-channel interference is a major factor in limiting the capacity and link quality in cellular communications. as the co-channel interference is modeled by lognormal distribution, sum of the co-channel interferences of neighboring cells is represented by the sum of lognormal random variables (rvs) which has no closed-form expression. assuming independent, identically distributed (iid) rvs, the...

Background: Cell-based treatment approach using differentiated mesenchymal stem cells (MSCs) and mature chondrocytes has been considered as an advanced treatment for cartilage repair. We investigated the differentiated level of these two cell types that is crucial for their repair capacity for cartilage defect at a co-culture micro mass system. Methods: Passaged-2 MSCs isolated from the mouse b...

there is no functional annotation for the majority of the several hundreds of receptor-like kinases in plants. a direct way of inferring the function of these proteins is to study the phenotype that results from loss of function mutants such as t-dna mutant lines. in this research a function (phenotype) to at2g37050 gene that encodes a receptor like kinase in arabidopsis t-dna line was assigned...

Objective(s): The present day challenge is how to obtain germ cells from stem cells to treat patients with cancer and infertility. Much more efforts have been made to develop a procedure for attaining germ cells in vitro. Recently, human umbilical cord-derived mesenchymal stem cells (HUMSCs) have been introduced with higher efficacy for differentiation. In this work, we tried to explore the eff...

Background: Tegument protein pp150 of cytomegaloviruses (CMVs) plays a vital role in all stages of viral life cycle, representing the most important tegument protein candidate for HCMV treatment. However, the exact role of pp150 in immune regulation is yet to be elucidated. Objective: To examine the effects of pp150 on the maturity and function of muri...

Background: The potential of plants, as a safe and eukaryotic system, is considered in the production of recombinant therapeutic human protein today; but the expression level of heterologous proteins is limited by the post-transcriptional gene silencing (PTGS) response in this new technology. The use of viral suppressors of gene silencing can prevent PTGS and improve transient expression level ...

objectives: platelets are anucleated fragments derived from megakaryocytes. it has been demonstrated that platelets play a role in hemostasis and innate immunity. in addition, platelets have a cd40 ligand which is an important molecular marker in motivating immune cells. thus, platelets also have a role in adaptive immunity as seen by their ability to activate b cells. since human platelet micr...

Introduction: Human hematopoietic stem cells (hHSCs) have been used for transplantation in hematologic failures. Because the number of hHSCs per cord blood unit is limited, the expansion of these cells is important for clinical application. It has been reported that cytokines and feeder layer provide a perspective to in vitro expansion of hHSCs. In this regard, cord blood CD34+ cells ex...

background: the hormones of hypothalamo-pituitary-gonadal (hpg) axis have facilitative effects on reproductive behavior in mammals. ghrelin as a starvation hormone has an inhibitory effect on hpg axis’ function. hence, it is postulated that ghrelin may reduce the sexual behavior through inhibiting of hpg axis. the aim of this study was to examine the effects of ghrelin and its antagonist, [d-ly...
