introduction: mouse embryos can successfully be frozen with sucrose and propandiol. however, different developmental stages of mammalian embryos have shown to have various capacities to undergo freeze-thawing procedure. in the present study, the ability of 1,2,4 and 8-ell mouse embryo to tolerate the freeze-thawing procedure was investigated and the effect of this procedure on the further in vi...

the plethora of studies indicated that there is a cross talk relationship between harmaline and serotonergic (5-ht) system on cognitive and non-cognitive behaviors. thus, the purpose of this study is assessment the effects of ca1 5-ht4 receptor on memory acquisition deficit induced by harmaline. harmaline was injected peritoneally, while 5-ht4 receptor agonist (rs67333) and antagonist (rs23597-...

Neospora caninum (N. caninum) is an apicomplexan parasite and causes abortion and congenital neosporosis in cattle worldwide. In this study, we evaluate the virulence of a N. caninum isolate on mouse strain C57BL/6. Six groups of five mice C57BL/6 were intraperitoneally inoculated with 1 × l07, 1.5 × l07, 2 × l07, 3 × l07 and 4 × l07 tachyzoites and a control inoculum of DMEM, respectively. Cli...

In this study granulocyte-macrophage colony stimulating factor (CSF) was prepared from rabbit and guinea pig lung tissues. The biological activity of these CSFs was measured on semisolid agar culture and compared with those of mouse and rat. Weight of animals, incubation time and cross-reactivity of CSFs with different bone marrow sources were also investigated. The results showed that both...

Background: Doxorubicin (DOX), a widely used antineoplastic compound, is associated with testicular damage and infertility. In this study, we intended to determine the possible preventive effects of simvastatin (SIM), a lipid lowering agent with antioxidant and anti-inflammatory activities, on testicular morphometric-stereological changes due to DOX treatment in mice. Materials and Methods: Mal...

introduction: demyelination is one of the main causes of neurological disability. it is the end product of numerous pathological processes, multiple sclerosis (ms) being the most common cause. more than 70% of the ms patients suffer from optic disturbances. this disease commonly affects the optic pathway, particularly the optic nerves and chiasm. several attempts have been made to produce a sui...

Rett syndrome (RTT) is a severe X-linked neurodevelopmental disorder that primarily caused by mutations in the methyl CpG binding protein 2 gene (MECP2). RTT second most prevalent genetic cause of intellectual disability girls, and there currently no cure for disease. We have previously shown therapy using self-complementary AAV9 viral vector expressing codon-optimized Mecp2 version (AAV9-MCO) ...

background: cancer immunotherapy attempts to stimulate the immune system to reject and destroy tumors and is one of the cancer treatment strategies. recently, interluekin36 (il36) has been used as immunotherapeutic agents in cancer gene therapy. present study investigated that the il36 gene therapy effects on the regression of tumor masses in mouse model. aim of this study is determination of t...

This research aims to evaluate the effect of low-level laser therapy (LLLT) on healing burn for mouse. Four mouses are divided into 4 groups. Group 1, 2, 3 irradiated by a wavelength 532nm, 850nm, and 940nm. is control group that has natural recovery. Low-level makes regenerative process, occurs faster, rehabilitation mouse activity during treatment.

introduction: adult stem cells are the group of cells which conserve their nature in tissues and organs among other cells. in recent years, the researchers reported the existence of stem cells on the bulge of hair follicles near to the smooth muscle. it is possible to differentiate these stem cells to neural cells by induction of shh, fgf, and ra factors. because of existence of these factors i...
