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...

objective (s):hyperglycemia is widely recognized as the underlying cause for some debilitating conditions in diabetic patients. the role of cannabinoid cb1 and vanilloid trpv1 receptors and their endogenous agonists, endovanilloids, in diabetic neuropathy is shown in many studies. here we have used pc12 cell line to investigate the possible influence of glucose concentration in culture medium o...

introduction dendritic cells (dcs) are bone marrow-derived cells, which migrate to lymphoid and non-lymphoid organs via blood. liver dcs are believed to play an important role in the regulation of hepatic allograft acceptance. however, because of inherent difficulties in isolating adequate numbers of dcs from liver, limited information is available on the phenotype and functions of liver dcs. t...

background: after improvements in various cancer treatments, life expectancy has been raised, but success in treatment causes loss of fertility in many of the survived young men. cryopreservation of immature testicular tissues or cells introduced as the only way to preserve fertility. however, freezing has some harmful effects. melatonin, a pineal gland hormone, has receptors in reproductive sy...

background and objectives: significant progress has been made in treatment of hemophilia. ex-vivo gene therapy is going popular due to the capability of this method in using isogenic cells for genetic manipulation and reintroducing them into same host after proliferation. most gene therapy techniques use viral vectors, which usually harbor a strong and non-specific promoter (e.g. cmv early prom...

testosterone is believed to play a significant role in spermatogenesis, but its contribution to the process of spermatogenesis is not completely understood. given that extracellular matrix (ecm) facilitates differentiation of spermatogonial stem cells (sscs) during culture, the present study was conducted to elucidate whether testosterone contribute to the permissive effect of ecm on sscs diffe...
