Macrophages play impor tant roles in inflammation and host defense against bacterial infection. T h e metabolites o f arachidonic acid (20:4) 1 are impor tant modulators o f these responses (1). When macrophages interact with stimuli such as an immune complex or a bacter ium, phospholipases are activated and 20:4 is l iberated f rom plasma mem b ran e phospholipids.

The Impact of Alcohol Consumption on Occupational Attainment in England In this study we provide evidence on the effect of alcohol consumption on occupational attainment in England. To do this we use samples of employees from the Health Survey for England between 1992 and 1996. We find that due to the endogenous nature of alcohol consumption, OLS estimates may provide a biased picture of the im...

This study aimed to evaluate the repellent effect of tea tree (Melaleuca alternifolia) and andiroba (Carapa guianensis) essential oils on two species of flies (Haemotobia irritans and Chrysomya megacephala). For the in vitro studies, free-living adult flies were captured and reared in the laboratory. To verify the repellency effect, an apparatus was constructed where H. irritans and C. megaceph...

(166)Ho-EDTMP is a major therapeutic agent which is widely used in bone palliation therapy. In this study, a (166)Ho-EDTMP complex was prepared successfully using an in-house synthesized EDTMP ligand and (166)HoCl(3). Ho-166 chloride was obtained by thermal neutron irradiation (1 Ã 10(13) ncm(â2)s(â1)) of natural Ho(NO(3))(3) samples (specific activity = 3â5 GBq/mg), dissolved in acidic media. ...
