Predation and competition can induce important density- and trait-mediated effects on species, with implications for community stability. However, interactions of these factors with parasitism remain understudied. Here we investigate interactions among competition, predation and parasitism by crossing tadpole density (Bufo americanus), presence of a caged predator (Notophthalmus viridescens), a...

background: there is evidence that cd36 promotes foam cell formation through internalizing oxidized ldl (ox-ldl) into macrophages therefore, it plays a key role in pathogenesis of atherosclerosis. in addition, cd36 expression seems to be mediated by nuclear receptor peroxisome proliferator-activated receptor gamma (ppar-γ). the aim of the present study was to evaluate and compare the effect of ...

nowadays, polymer blends usages increase more and more in order to produce materials with better properties. according to many research works, the blends of polyolefins have shown industrial importance. the purpose of this project was to carry out some investigations on fibers melt spun from the polypropylene and low density polyethylene blends. pp and ldpe are immiscible. pp/ldpe blend filamen...

The exposure of HL-60 human promyelocytic leukemia cells to 0.5 MM5-fluoro-2'-[3H]deoxyuridine (FdUrd) for 16 hr resulted in the incorporation of 5.14 ±0.31 (S.D.) x 10~7 mol FdUrd into DMA per mol of DMA nucleotide, which corresponds to 0.146 ± 0.082 pmol FdUrd per 107 cells. Pretreatment with 50 MMdeoxythymidine for 24 hr led to a 2.7-fold increase in the incorporation of this analogue into...
