WITH THE growing interest in the metabolism of cholesterol esters, procedures have been developed which frequently make desirable the use of chemically pure compounds. Some of the radioactive cholesterol esters are either commercially unavailable or expensive when made to order. The high cost of the starting materials (cholesterol-4-CI4, pure fatty acids) makes it desirable to have a good yield...

an investigation was made to study the residual activity and air- borne effect of pirimiphos- methyl, at 2g a.i./m2 in hut scale trials on different surfaces in kazeroun, and bandar-abbas, south of iran. in kazeroun area, bio-assay contact mortality test with pirimiphos methyl on mud, wood, cement and plaster surfaces, 54 days after hut spraying, decreased from 100% to 46.7%, 61.25%, 36.6% and ...

abstract salinity stress is among the major barriers to plant production in many parts of the world, especially in arid and semi-arid areas. jasmonates are one of the newest plant growth regulators that reduce the damages caused by environmental stresses. in this study, the effects of salinity and methyl jasmonate on some morphological traits of chamomile including root and shoot lengths, fresh...

Isoprostanes F(2) are arachidonate autoxidation products in mammals that have been shown to be induced during several human disorders associated with enhanced free-radical generation. Isoprostanes F(2) represent not only extremely reliable markers of oxidative stress in vivo, but they also exert potent biological effects. Therefore, it has been postulated that isoprostanoids are mediators of ox...
