background : the study was aimed to show the effect of molecular mechanism of aqueous garlic extract (age) on expression of ifnγ and inos genes in leishmania major . methods : leishmania major promastigotes (mrho/ir/75/er) were added to the in-vitro cultured j774 cell line, the cells were incubated for 72 hours. various concentrations of garlic extract (9.25, 18.5, 37, 74, 148 mg/ml) were added...

calcium-binding proteins play essential roles in the cell. one important class of calcium-binding proteins is the annexin family. this is a family of 13 proteins, which binds to phospholipids in a calcium-dependent manner. osteosarcoma cell line (mg-63) is a transformed cell that has many characteristics of the differentiated cell, such as a considerable serum dependency in its growth rate. usi...

  Background and Objective: Pneumocystis pneumonia (PCP) has been historically the most prevalent opportunisticinfection in patients infected with the human immunodeficiencyvirus. Culture of the organism has not been faced with suitable success in artificial media, while various results have been reported for cell culture media. The aim of this study was proliferation of Pneumocystis carin...

background: adipose tissue has characteristics of an endocrine organ which releases a number of adipocyte-specific factors, known as adipocytokines.  it has recently suggested that adipocytokines might play a role in pathogenesis and progression of certain cancers, especially in gastric cancer.  this study has managed to investigate endogenous and/or exogenous expression of visfatin and resisti...

background: mehr-80 is a newly established adherent human large cell lung cancer cell line that has not been transfected until now. this study aims to define the optimal transfection conditions and effects of some critical elements for enhancing gene delivery to this cell line by utilizing different non-viral transfection procedures. methods: in the current study, calcium phosphate (cap), deae-...

many cell lines, when cultured under proper conditions, can form three dimensionalstructures called multicellular spheroids. these spheroids resemble in vivo tumor models in severalaspects. therefore, studying growth characteristics and behavior of spheroids is beneficial inunderstanding the behavior of tumors under various experimental conditions. in this work, we havestudied the growth proper...

objective(s): binary hybrids of chitosan-zeolite have many interesting applications in separation and bacteriostatic activity. materials and methods: template free zsm-5 zeolite was synthesized by hydrothermal method, physical hydrogels of nano chitosan in the colloidal domain were obtained in the absence of toxic organic solvent and then nano chitosan/zsm-5 hybrid composites with nano chitosan...
