in this research iron manganese oxide nanocomposites were prepared by co-precipitation, sol-gel and mechanochemical methods by using iron (iii) nitrate, iron (ii) sulfate and manganese (ii) nitrate as starting materials. these nanocomposites were prepared in the presence of various catalyst beds. the polyvinyl pyrrolidon (pvp) was used as a capping agent to control the agglomeration of the nano...

The present study was designed to examine the effects of lead nitrate (LN) and whether selenium has a cardioprotective effect on diabetic and non-diabetic rats. Selenium and LN were administered orally for 28 days to streptozotocin-induced diabetic and non-diabetic rats. Animals were divided into 8 groups: control, sodium selenite, LN, LN+Sodium selenite, diabetic-control, diabetic sodium selen...
