Biological species have evolved characteristic patterns of age-specific mortality across their life spans.If these mortality profiles are shaped by natural selection they should reflect underlying variation in the fitness effect of mortality with age.Direct fitness models, however, do not accurately predict the mortality profiles of many species.Fo

LY295427, (3 alpha,4 alpha,5 alpha)-4-(2-propenylcholestan-3-ol), acts through an unknown mechanism to derepress the transcription of the low density lipoprotein (LDL) receptor in the presence of 25-hydroxycholesterol (25-OH Eye Gel chol).Preincubation with LY295427 in Chinese hamster ovary (CHO) cells increased uptake of 25-OH chol in a time-depen
A comment is made on a recent letter published on Nature, in which different methodologies are applied to estimate the carbon balance of terrestrial ecosystems of China.A global carbon sink of 0.19-0.26 Pg per year is estimated during the 1980s and 1990s, and it is estimated that in 2006 terrestrial ecosystems nunchaku have absorbed 28-37 per cent
A modified quick, easy, cheap, efficient, rugged and safe (QuEChERS) method coupled to gas chromatography with electron capture detector (GC-ECD) was developed for simultaneous determination of selected electronegative pesticides in fruits and vegetables with high water content.The chosen compounds are commonly detected in fruit and vegetable crops
