rate of in vitro maturation of oocytes is one of the challenges of assisted reproductive techniques. in this study we investigated the effects of supplementation of cysteamine on the rate of in vitro maturation of oocytes in two different media. germinal vesicle oocytes were collected from mouse ovary and cultured in two media (tcm199 and meme) with 0, 50, 100, 200, 500 µm/ml cysteamine. number...

background: dominant lactic acid bacteria (lab) originally isolated from traditional non-dairy fermented foods, may harbor unique characteristics such as probiotic properties. in this research, probiotic potential of dominant lab isolated from pickled garlic was studied. methods: after isolation of dominant lab from pickled garlic produced with apple cider vinegar, the isolate was identified by...

introduction: spreading depression (sd) is a propagating wave of depolarization followed by depression of the neuroglial activities and can modulate extracellular dopamine concentrations in the neocortex. it has been shown that the dopaminergic system plays a role in migraine. sd has been suggested as a critical phenomenon in the pathophysiology of migraine. the aim of this study was to investi...

background: endometrial secretion analysis is a non-invasive and promising method in evaluation of endometrial receptivity. objective: the aim of the present study was to assess the relationship between the success rate of ivf procedures and some endometrial secretion cytokines, including interleukin-1β (il-1β), tumor necrosis factor (tnf-α), interferon gamma-induced protein 10 (ip-10), and mon...

objective: to evaluate the efficacy of in vitro sperm activation (isa) using non-liquefied versus liquefied asthenozoospermic semen samples for improvement of sperm parameters. materials and methods: fifty six oligoasthenozoospermic (oa) patients (age range: 22-44 years; mean: 32.089 years) were enrolled in this study. oa patients were classified according to type of infertility. also, duration...

traumatic brain injury (tbi) is caused by rapid deformation of the brain, resulting in a cascade of pathological events and ultimately neurodegeneration. in vitro models of tbi can help us to describe the pathobiological mechanisms. in vitro models of brain injury support a platform for performing repeatable, well-controlled, environmentally isolated experiments. other advantages of in vitro mo...

results the results obtained for each drug were compared with other drugs and also with the results of the control groups. the results related to promastigote and amastigote assays showed that when the dose of both drugs increased, the parasite number is reduced in comparison with the control groups. moreover, the parasitic burden in the test cultures decreased significantly. macrophage assay r...

background: infertility is an increasing medical and social problem. in vitro fertilization (ivf) has become a common and accessible treatment for a wide variety of indications that have variable outcomes. natural killer (nk) cells have been identified as relevant immunological factors involved in reproductive success or failure. objective: the aim of this study was to compare the percentage of...
