objective: helicobacter pylori has a well-established role in the development of gastric cancer. in vitro studies reveal increased proliferation of the gastric mucosa in the presence of h. pylori infection. it has been also shown that production of some cytokines, such as interleukin-1 beta (il-1b) is increased in h. pylori infection. in addition, il-1b increases proliferation of gastric epithe...

background: this study was undertaken to investigate the efficiency of two different embryo somatic cell co-culture conditions tissue culture medium 199 (tcm199)–vero cells and menezo b2 (b2)-vero cells for the in vitro developmental quantity and quality of bovine embryos. materials and methods: bovine oocytes were allowed to mature and subsequently undergo fertilization in vitro. their presump...

objective: the development of combining mesenchymal stem cells (mscs) with surface modified three-dimensional (3d) biomaterial scaffold provides a desirable alternative for replacement of damaged and diseased tissue. nanofibrous scaffolds serve as suitable environment for cell attachment and proliferation due to their similarity to the physical dimension of the natural extracellular matrix. in ...

in this paper the fixed point theorem of schauder is used to prove the existence of a continuous solution of the nonlinear fuzzy volterra integral equations. then using some conditions the uniqueness of the solution is investigated.
