introduction: the systemic and local content of inflammatory cytokines and chemokines play substantial roles in pathophysiology of arthritis. this study was purposed to verify the roles of synovial tnf-α, il-6 and fractalkine (fkn) in edema changes during different stages of complete freund’s adjuvant (cfa)-induced knee arthritis in rats. methods: 168 male wistar rats were divided in 7 groups a...

the reaction of an equivalent of 2- mercaptoethyl ammonium chloride with an equivalent of 2,6-diformyl -4- methyl phenol produced monoamine which was reacted with half equivalent of 1,2-diamine ethane to produce ethylene-bis-6-(2-mercapto-ethyl-imine)-methyl -4- methyl phenol [h4l]. the ligand was reacted with metal ions[cr(iii), mn(ii), fe(ii), co(ii), ni(ii), cu(ii), zn(ii), cd(ii), and hg(ii...

in this paper, lift and drag coefficients were numerically investigated using numeca software in a set of 4-digit naca airfoils. two metamodels based on the evolved group method of data handling (gmdh) type neural networks were then obtained for modeling both lift coefficient (cl) and drag coefficient (cd) with respect to the geometrical design parameters. after using such obtained polynomial n...

endometriosis is an estrogen dependent disease. levels of cancer antigen-125 are significantly higher in women with moderate to severe endometriosis. however, patients with unruptured endometriosis rarely have serum ca-125 levels more than 1000 u/ml. this case report presents a diffuse, unruptured ovarian endometrioma in a 29- year-old woman, leading to an extraordinary high serum ca-125 and ca...

to the best of our knowledge, imaging of accidental exposure to radioactive fluorine-18 (f-18) due to liquid spill has not been described earlier in the scientific literature. the short half-life of f-18 (t½=110 min), current radiation safety requirements, and good manufacturing practice (gmp) regulations on radiopharmaceuticals have restrained the occurrence of these incidents. the possibility...

background: there are many studies to investigate the effects of each interacting component of tumor-immune system interactions. in all these studies, the distinct effect of each component was investigated. as the interaction of tumor-immune system has feedback and is complex, the alternation of each component may affect other components indirectly. objective: because of the complexities of tum...

objective: obesity increases production of the extracellular matrix (ecm) role in pathological cardiovascular damage. regular exercise and the use of medicinal plants, particularly celery, in damage to be effective. the aim of this study is to investigate the changes in matrix metalloproteinases 2,9 (mmp 2,9) and tissue inhibitor of matrix metalloproteinase 1 (timp-1) with synchronized exercise...

the complexation reactions between mg2+, ca2+, sr2+ and ba2+ metal cations with 15-crown-5 (15c5) were studied in acetonitrile (an)-methanol (meoh) binary mixtures at different temperatures using conductometric method. 15c54 forms 1:1 complexes with mg2+, ca2+ and sr2+ cations in solutions. the ma2+ cation forms a 2:1 complex (ratio of lighand to cation) in solutions. a linear relation was obse...
