objective: the aim of the present study was to investigate the effect of protein and dna components of toxoplasma gondii on maturation of dendritic cells and their efficiency in il-12 production and proliferation of t cells. materials and methods: for dc generation, bone marrow cells were cultured in the presence of gm-csf and il-4 for 5 days. tumor lysate and protein or dna components of toxo...

background: dendritic cells (dc) induce tumor or pathogen-specific t cell responses in humans. several laboratories have developed culture systems, including maturation factors for human dc from peripheral blood monocytes. we comprehensively compared standard maturation stimulus, an autologous monocyte-conditioned medium (mcm), with heparin for their ability to promote uniformly mature dc that ...

background: ammonium is produced in culture medium due to amino acids degradation and has adverse effect on in vitro culture of embryo. in the current study, the purpose was to evaluate the effects of ammuniom chloride (ac) on in vitro oocyte maturation rate and early embryo development in the sheep and its effect on the expression of bcl-2. methods: in vitro maturation (ivm) was performed in t...

dendritic cells (dcs) induce pathogen-specific t cell responses. we comprehensively studied the effects of addition of maturation stimulus, fibroblasts (fibroblast conditioned medium), pha activated t cells (t cell conditioned medium), and mixture of fibroblast & pha activated t cells (fcm-tccm) conditioned media on maturation of dcs. monocytes were cultured with gm-csf and il-4 for five da...

The increasing interest in the extraordinary thermal properties of nanostructures has led to the development of various measurement techniques. Transient thermoreflectance method has emerged as a reliable measurement technique for thermal conductivity of thin films. In this method, the determination of thermal conductivity usually relies much on the accuracy of heat capacity input. For new nano...

Background: 15% of oocytes collected in ART cycles are immature. These oocytes may be matured following IVM program. It is possible to cryopreserve the immature oocytes for further use in ART after application of IVM. The aim was to determine the maturation rate, morphology and viability of human immature oocytes after fresh IVM and vitrified-IVM program. Materials and Methods: 63 women who und...
