Mammalian cells can metabolize linoleic acid (C,8:2, , , , , ) by A-6-desaturation to y-linoleic acid (C18:3,,,-,,), which can be elongated to dihomo-y-linoleic acid (C211.3,,z, ), and subsequently undergo A-5-desaturation to arachidonic acid (AA) (C211:J,rr-,,) 11 I . Most freshwater fish are also capable o f this process 121, whereas marine species such as turbot (Scopthulmirs maximus) appare...

The enzymatic conversion of adenosine-to-inosine (A-to-I) in RNA rewrites the informational output of a number of different classes of coding and non-coding RNA transcripts. In this issue, Decher et al (2010) reveal a new functional consequence for an ancient RNA editing site in certain animal voltage-gated K channel (Kv) genes. Abundant highly unsaturated fatty acids (HUFAs), which are essenti...

Migrating juvenile wild Chinook salmon Oncorhynchus tshawytscha, collected and loaded onto transport barges at Lower Granite Dam on the Snake River, were sampled from barges at John Day Dam, 348 km downstream, at 5 day intervals beginning in late April and ending in late May. An increase in lipid peroxidation and decrease in vitamin E in liver were observed from early to late in the barge trans...

the objective of this study was to evaluate the effect of five dosage of vitamin c (0, 50, 250, 750 and 1500 mg vitamin c per kg diet) on fatty acid composition of caspian brown trout fry (salmo trutta caspius). fish (initial average body weight of 0.1 ± 0.02 g) were fed by formulated diets for 6 weeks in triplicate. the findings of growth parameters and survival showed significant difference a...
