objective: curcumin, is the active component in turmeric (curcuma long). this agent induces apoptosis via inhibiting various signaling pathways. however, its poor aqueous solubility prevents its widespread application. in this study, dendrosomes with water-solubility, nano-sized dimensions and nontoxic properties, was used for curcumin delivery to cells. materials & methods: in the present...

dead yeast cells are an abundant residue of the brazilian ethanol industry and the industries still don’t have a proper or desirable destiny for all these cells, which means tons of vitamins and proteins that have not a major end. in the other hand, heavy metal residues are a problem, especially for leather industry, where brazil is also a great producer. in this work, dead yeast cells were use...

introduction: spinal cord injuries (sci) lead to permanent irreversible functional deficits.  poor prognosis of patients is the motivation of searching a treatment for the chronic injury.  planting stem cells provides us with a promising strategy. in the meanwhile, the use of olfactory ensheathing cells (oecs) has shown very good results.  this study aims at evaluating the effect of transplante...

to follow-up the present study, 40 mature female rats were used. the animals were divided into test,control and sham groups. the rats in the test group were laparotomized and unilateral ovariectomy was done. on the 1st and 2nd met-oestrous after operation, the tissue samples were dissected out and processed for histological study. the intact ovary in the test group underwent a significant (p

objective: dendritic cells (dcs) play a critical role in the beginning and in the course of immune responses. by observing. considering the defect in these cells in patients with tumor malignancy. in recent years there has been considerable interests in correction and use of these cells. in our prvious studies we showed that lysate of listeria monocytogenese can induce maturation of dendritic c...

intestinal stem cells (iscs) are a group of rare cells located in the intestinal crypts which are responsible for the maintenance of the intestinal homeostasis and intestinal regeneration following injury or inflammation. lineage tracing experiments in mice have proven that iscs can repopulate the entire intestinal crypt. it is noteworthy that in such experiments, only a subset of intestinal cr...

background & aim: low back pain is broadly documented as one of the most widespread pathologies in the advanced domain. although the reasons of low back pain are uncountable, it has been meaningfully related to intervertebral disc degeneration. present therapies for intervertebral disc (ivd) degeneration such as physical therapy and spinal fusion reduce symptoms' severity, but do not treat the ...

the immune system of mammalian organisms undergoes alterations that may account for an increased susceptibility to certain infections, autoimmune diseases, or malignancies. well characterized are age related defect in t cell functions and cell mediated immunity. although it is well established that the functional properties of t cells decrease with age, its biochemical and molecular nature is p...

allergen-specific immunotherapy (ait) has been recently considered as an alternative approach to ameliorate the symptoms of allergen exposure and improvement the patients’ quality of life. dendritic cells (dc) in the forms of tolerogenic or th1-induced cells have been investigated in several studies as one of the promising approaches of ait in allergic diseases. the aim of this study was to eva...

a central role for t cells and their cytokines in the pathogenesis of psoriasis has been proposed; however, there are controversies over the details of this issue. the goal of this study is to summarise currently available data on the importance of t cells in psoriasis pathogenesis. a  systematic  review  of  the  english  medical  literature  was  conducted  by  searching pubmed, embase, isi w...
