multiple sclerosis is an inflammatory disease of the central nervous system in which t cells experience a second phase of activation, which ultimately leads to axonal demyelination and neurological disability. the recent advances in stem cell therapies may serve as potential treatments for neurological disorders. there are broad types of stem cells such as neural, embryonic, mesenchymal and hem...
sange siyah dam is located two kilometers down the kabod khani village. the environ of ghorrve city in kurdestan province. this is an clay core dam. in this dam instrumentation is performed in three section and consist of electrical piezometers, total pressure cells, settlement cells and so on. the main objective of instrumentation is to control the behavior of dam body and foundation, end else...
germline and somatic stem cells are distinct types of stem cells that are dedicated to reproduction and somatic tissue regeneration, respectively. germline stem cells (gscs), which can self-renew and generate gametes, are unique stem cells in that they are solely dedicated to transmit genetic information from generation to generation. we developed a strategy for the establishment of germline st...
background and aims: natural killer t (nkt) cells have been suggested to play critical roles in a wide range of immune responses especially against hepatotropic pathogens such as hepatitis c virus (hcv). in the present study, we investigated the status of nkt cells by producing interleukin-17 cytokine in peripheral blood. patients and methods: as case-control study, 15 patients wi...
background t-helper (th) lymphocyte cytokine production may be important in the immune pathogenesis of hepatitis c virus (hcv) infections. th1 cytokines such as; interleukin- 2 (il-2), and interferon gamma (ifn-gamma) are necessary for host antiviral immune responses, while th2 cytokines (il-4, il-10) can inhibit the development of these effector mechanisms. objectives the aim of the present st...
conclusions large amounts of preclinical studies have been made of stem cells and there is an increasing interest to perform these studies within the human population but preclinical studies are insufficient; therefore, much more and efficient studies should be conducted to evaluate the efficacy and safety of stem cells. context musculoskeletal injuries may be painful, troublesome, life limitin...
background: several studies have demonstrated the immunosuppresive effects of mes-enchymal stem cells (mscs) in allogeneic or mitogenic interactions. cell-cell contact inhibition and secretion of suppressive soluble factors have been suggested in this re-gard. objective: to investigate if adipose derived mscs could inhibit jurkat lym-phoblastic leukemia t cell proliferation during coculture. me...
age related cytochemical changes of thymic endocrine cells were studied in 78 day old chicks at five day interval to age of day 60 employing a panel of cytochemical stains. methenamine silver revealed cell morphology including cell processes distinctly while diamine silver revealed a stronger argentaffinity in these cells. the cells had greater affinity for diamine silver compared to methenamin...
چکیده بیماری سرطان دومین علت مرگ و میر در جهان به حساب می آید. درمان های دارویی متداول سرطان اغلب دارای اثرات درمانی کوتاه مدت بوده که در برخی از موارد هم منجر به مقاومت دارویی می گردند. در این بین استفاده از ترکیبات طبیعی نشأت گرفته از گیاهان بسیار مورد توجه قرار گرفته چرا که هم دارای اثرات درمانی مفیدی بوده و هم اینکه عوارض جانبی چندانی ندارند. در پژوهش حاضر، اثرات سمیت سلولی و تخریبی dna ما...
