multiple sclerosis (ms) is a complex polygenic disease in which gene-environment interactions are important. a number of studies have investigated the association between tumor necrosis factor-α (tnf-α) -308 g/a polymorphism (substitution g→a, designated as tnf1 and tnf2) and ms susceptibility in different populations, but the results of individual studies have been inconsistent. therefore, per...

in the present study, an efficient protocol has been developed for callus induction and production of ra in callus culture of satureja khuzistanica for the first time. in vitro callus induction was achieved from young shoot tip explants cultured on ms and b5 media supplemented with different concentrations of iba (0.1, 1.0, 2.0 and 5.0 mgl-1) solely or in combination with cytokinins bap and kin...

background multiple sclerosis (ms) is a demyelinating condition affecting the central nervous system. although the cause of this condition is unknown, patients with ms seem to have genetic vulnerability to certain environmental factors such as infection that could trigger this condition. objectives we conducted this study to determine whether ms risk increases following primary infection with e...

two separate factorial experiments were conducted to study the effects of explant sources, plant growth regulators, sucrose concentrations, and light conditions on in vitro cormlet formation of freesia (freesia ×hybrida bailey 'argenta'). interestingly, it was observed that the pupae had lower contamination levels compared to mother corms. using 40% sodium hypochlorite solution for 40 min, cont...
