objective: escherichia coli (e.coli) o157:h7 is one of the most important pathogenic causes of hemorrhagic colitis in humans. cattle are the main reservoirs of this bacteria and vaccination is a key mechanism for its control. the intimin, translocated intimin receptor (tir), and espa proteins are virulence factors expressed by the lee locus of enterohemorrhagic e. coli. espa protein is a member...

Introduction For in vivo inhalation studies, aerosol dosimetry links exposure and deposited dose within the respiratory tract. Aerosol programs like Multiple Path Particle Deposition model utilize tract geometry, physiology, properties to predict particle deposition A challenge wider use of these for studies is lack species-specific or strain specific anatomy, some cases, physiology data. The o...

Background: Melanoma progression and metastasis is suggested to be mediated by increased accumulation of myeloid derived suppressor cells. Various chemotherapeutic drugs such as 5-Fluorouracil in single low concentration have the capacity, at least in part, to reverse tumor progression by reducing myeloid derived suppressor cellsmediated immunosuppression. Objective: To assess whether multiple ...

Objective(s): Ceftriaxone (Cef), a beta-lactam antibiotic, is accompanied by antioxidant and anti-inflammatory properties. It has been shown that Cef has beneficial effects on Alzheimer’s disease. In the current investigation, the effect of Cef in a mice model of aging was investigated. Materials and Methods: Forty male mice were equally...

Introduction: Epilepsy is one of the most common neurologic disorders. Pharmacoresistance and adverse effects of current antiepileptic drugs (AEDs) necessitate development of new drugs and strategies for treatment of epilepsy. Omega 3-Polyunsaturated fatty acids (ω3-PUFAs) are safe nutritional supplements that recently considered for treatment of epilepsy. Anticonvulsant effect of docosahexa...

Objective(s): Fetal microchimerism is the persistence of allogeneic cell population that transfer from the fetus to the mother. The aim of this study was to evaluate the presence of fetal microchimerism in the pancreas of the mouse with acute pancreatitis (AP).Materials and Methods: In this experimental study, female wild-type mice were mated with male EGFP+. AP model was obtained by injection ...

Objective(s): To design a multivalent DNA vaccine encoding the most immunogenic regions of the Leishmania major antigens including TSA (Thiol-specific antioxidant protein), LmSTI1 (Leishmania major stress-inducible protein1), LACK (Leishmania homologue of receptors for activated C Kinase), and KMP11 (kinetoplastid membrane protein-11) on BALB/c mice.M...

objective(s):experimental allergic encephalomyelitis (eae) is an autoimmune disease validated as animal model of multiple sclerosis (ms). administration of genistein, a phytoestrogenic component of soy, to mice at the onset of eae is known to attenuate the clinical signs of the disease. the potential effects of genistein on established eae is less studied. in the current study, we aimed to comp...

objective: testicular cell transplantation has been widely used to investigate the restoration of fertility in rodent models. in this research we apply transplantation as a treatment method in the cryptorchid model and compare this method with orchidopexy, which is the routine treatment for this problem. we studied the controversial effects of treatment on the number of germ cells and other mor...

background: the purpose of this study was to evaluate antileishmanial effects of asa via no pathway in leishmania major infected balb/c mice. moreover, toxicity and pathological consequences of asa administration were investigated. methods: balb/c mice were infected with l. major and asa was inoculated orally after lesion appearance for its ability to modulate no and to modify leishmania infect...
