in this study, symbiotic yog-ice (rozen yogurt) was produced that was inoculated with different levels of inulin(0,2.5 amd 5%)as prebiotic compound and lactobacillus casei as probiotic bacteria in two types; free and encapsulated with sodium algint-whey protein concentration for low fat yog-ice cream.the survivability of this probiotic bacteria was evaluated under simulated gastro-intestinal co...

objective: mesenchymal stem cells (mscs) can differentiate into various cell types. since cysteine has structural similarities to neuronal inducers β-mercaptoethanol and glutathione, we examined its effect on neural induction of rat bone marrow mscs. materials and methods: in this experimental study, cells were treated in a medium containing 1mm cysteine for 24 hours prior to treatment with neu...

Studies have shown that symptomatic improvement of cryptosporidiosis in immunocompromised patients is possible following treatment with" hyperimmune" colostrum containing anti-sporozoite antibodies from cattle immunized with Cryptosporidium parvum antigens. The contribution to immunity of antibodies developed during Cryptosporidium infection is unclear, however. Previously, we showed that ...

Objective(s): Populus species have various pharmacological properties, including antioxidant activity. In this study, the effects of Populus tomentiglandulosa extract (PTE) on histopathology and antioxidant enzymes in the rat liver and kidney were examined.  Materials and Methods: Sprague-Dawley rats were assigned to three groups; (1) no...

introduction : deproteinized bovine bone mineral (bio-oss) is a xenogenic bone substitute, widely used in maxillofacial bone regeneration. the aim of this in vitro study was to investigate its influence on the growth behavior of human osteosarcoma cell line, saos-2 culture, and compare it with the physiologic dose of dexamethasone, an inductive factor for osteoblasts. materials and methods: hum...

Background: IFN-g is mostly secreted by activated CD4+ , CD8+ T cells and NK cells. This cytokine has immunomodulatory, anti-cancer and anti-microbial effects and is important for prophylaxis, diagnosis and treatment of chronic infections and cancers. Objective: The purpose of this study was to clone the full cDNA of human IFN-g and express it in CHO cell line. Methods: Lymphocytes from a healt...

retinal pigment epithelium is responsible for maintaining the structural integrity of the retina by an efficient defense against free radicals, photo-oxidative exposure and light energy. for this purpose the main rpe line of defense is melanosomes. melanin content of retinal pigment epithelium cells in adults and neonates reveals remarkable variations. in the current study we compared melanogen...
