periodontal regeneration is a main aspect in the treatment of teeth affected by periodontitis. periodontal regeneration in furcation areas is quite challenging, especially when it is in interproximal region. there are several techniques used alone or in combination considered to achieve periodontal regeneration, including the bone grafts or substitutes, guided tissue regeneration (gtr), root su...

present research was conducted with the aim of determination of significant effect of soil properties on natural regeneration of haloxylon aphyllum and correlation coefficient and linear relation between soil variables and natural regeneration of haloxylon aphyllum. firstly, geomorphologic units were prepared in the areas under cultivation of haloxylon aphyllum in ardestan. two cultivated lands...

two potassium oxalate doped tio2 samples, designated as k1-tio2 and k2-tio2, were synthesized by the base-catalyzed sol-gel process. these samples were impregnated into rubber sheets. two commercial tio2 samples, anatase and degussa p25, were used as reference materials with which the synthesized samples were to be compared. anatase and p25 were also impregnated into rubber sheets and designate...

Among different doses of gamma rays, 1.5 kR induced 71.84% callus in Basrnati rice in amodified MS medium and 2% redifferentiation under anon-saline environment, 20% callusing response with 7.5%,2.8% and 2.5% redifferentiation was induced by 2.0 kR at electrical conductivity (EC) of 4,s and 6 dS.m of NaCl respectively, in regeneration medium. A non-irradiated non-saline environment reveale...

mesenchymal stem cells (mscs),as the major stem cells for cell therapy, have been studied from different aspects in pre-clinical and clinical settings for more than a decade. these cells modulate the immune system (humoral and cellular immune responses) in vitro by producing soluble factors (anti-inflammatory molecules) and/or making cell-cell contacts. hence they could be used in regenerative ...
