Heavy metal metals are non-biodegradable, have a remarkable ability to transfer through food chains and are potentially toxic for organisms.They are introduced tomarine environment via different anthropogenic sources. In this study, the ability of titanium dioxide nano-particle in transfer of Cr, Cu, Pb and Se metal through an aquatic food chain involving Ceratium tripos as the phytoplankton Da...

results results of the current study showed that the minimum inhibitory concentration value of cinnamaldehyde against m. tuberculosis was 200 µg/ml. moreover, rt-pcr data showed that a total of 25 genes were regulated by the cinnamaldehyde. of these, 12 genes were up-regulated, and 13 genes were down-regulated. conclusions cinnamaldehyde is a pattern to expand the new anti-tb drugs, because the...

objective(s):genetic and environmental factors are involved in the pathogenesis of systemic lupus erythematosus (sle). autoreactive lymphocytes are cleared through apoptosis and any disturbance in the apoptosis or clearance of apoptotic cells may disturb tolerance and lead to autoimmunity. vitamin d has anti-proliferative effects and controls cell cycle progression. in this study we investigate...

objective: osteoblasts arise from multipotent mesenchymal stem cells (mscs) present in the bone marrow stroma and undergo further differentiation to osteocytes or bone cells. many factors such as proteins present in the wnt signaling pathway affect osteoblast differentiation. ror2 is an orphan tyrosine kinase receptor that acts as a co-receptor in the non-canonical wnt signaling pathway. howeve...
