In activated sludge system, the removal of As may be contributed mainly to the surface adsorption of activated sludge.
On the other hand metal ions from the filter material may react with dissolved sulfide ions to form metal sulfides as colloidal suspension, which were coagulated and precipitated and finally filtered out, this mechanism may be contributed mainly to sulfide removal in the filtration tank.
This may indicate that in solid DS-sarcomas the tumour cells and not the stromal cells contribute mainly to the proteolytic activity of uPA.
The uPA/plasminogen system may contribute to metastasis mainly by ECM degradation.
Although they secreted numerous angiogenic factors, these cells did not exhibit any significant proliferation, suggesting that they may contribute to neovascularisation mainly through migration and incorporation into the vascular wall.
Uric acid and xanthine oxidase may contribute to kidney fibrosis mainly by inducing inflammation, endothelial dysfunction, oxidative stress, and activation of the renin-angiotensin system.
After taking into account the results of all the important experimental studies mentioned above, UA and XO may contribute to kidney fibrosis mainly by inducing inflammation, endothelial dysfunction, oxidative stress, and activation of RAS.
Second, the iodine status of the subjects was not studied, so excess iodine nutrition or iodine deficiency in these regions may contribute to thyroid disorders, mainly subclinical hypothyroidism [ 18].
Given that inhibiting Akt results in a reduction of Bcl-w levels, these results suggest that Akt may contribute to Bcl-w protective effects mainly by regulating its intracellular levels.
This is important from scientific perspective mainly because it may contribute to the study epidemiological patterns where the gathering of individualized socioeconomic information is not feasible.
