background: leukemia inhibitor factor (lif) is a very important pleiotropic cytokine which belongs to interleukin-6 (il-6) family. lif exerts multiple effects on different types of cells and tissues with numerous regulatory effects in vivo and in vitro. it is a lymphoid factor, which performs a number of activities including cholinergic neuron differentia­tion, control of stem cell pluripotency...

purpose: to assess hoffer correction factor in measurement of axial length (al) in eyes with phakic iol implants. methods: in this descriptive historical cohort study, axial length was measured by ultrasound (us) and iol master in both phakic and pseudophakic modes in 24 eyes of 14 patients with artisan intraocular lenses (iols) implanted for refractive purposes, hoffer’s suggested formula for ...

Objective: The goal of this research was to determine the influence of 4 weeks aerobic training on gene expression of tumor necrosis factor alpha (TNF-α), hypoxia-inducible factor-1 alpha (HIF-1α) and vascular endothelial growth factor (VEGF) in the cardiac tissue of diabetic rats. Materials and Methods: In an experimental study, 30 male wistar rats were partitioned into three groups (n=10), d...

many investigators are interested in finding the new cultural systems that can support the in vitro development of pre-implantation embryos better. previous studies suggested that growth factors such as epidermal growth factor (egf) are important in pre-implantation embryo development and implantation process. on the other hand, it is very important to support post thaw development of frozen em...

background: elongation factor-1, a conserved nuclear protein coding gene was used to identify iranian sandfly species. the phlebotomine sandfies are the vectors of the parasitic protozoan leishmania, the causative agents of leishmaniasis, in iran. methods: seven sets of primers were tried. pcr amplification of elongation factor-1 was successfully achieved for all 14 species of iranian sandfli...
