Oxidation of an oil rich in docosahexaenoic acid compared to linoleic acid in lactating women [PDF]

open access: yes, 1999
Background: We studied the oxidation of an oil rich in docosahexaenoic acid (DHA; DHASCO(R)) in lactating mothers receiving a dietary DHA supplement or a placebo. The results were compared with the oxidation of linoleic acid.

Oxidation with the 'O-2-H2O2-vanadium complex pyrazine-2-carboxylic acid' reagent - 9. Oxidation of cyclohexene and decalin

open access: yes, 2015
The oxidation of cyclohexene with hydrogen peroxide catalyzed by a vanadium complex and pyrazine-2-carboxylic acid (PCA) in air results in the formation of cyclohex-2-enyl hydroperoxide as the main product and cyclohex-2-enol, cyclohex-2-enone, cyclohex ...

Lewis Acid Catalyzed Cycloadditions [PDF]

open access: yes, 1982
This thesis describes an attempt to develop a potentially useful route to seven-membered carbocycles. α-Diketones and their enol ether derivatives were proposed to be suitable three-carbon cycloaddition dienophiles when complexed with a Lewis acid ...

AAK‑2 and SKN‑1 Are Involved in Chicoric-Acid-Induced Lifespan Extension in Caenorhabditis elegans

open access: yes, 2019
Chicoric acid is a dicaffeoyl ester with many bioactivities, including antioxidation, antidiabetes, and anti-inflammation. A previous study reported that chicoric acid extended the lifespan in Caenorhabditis elegans; however, the mechanism behind the ...

A motif unique to the human DEAD-box protein DDX3 is important for nucleic acid binding, ATP hydrolysis, RNA/DNA unwinding and HIV-1 replication

open access: yes, 2011
DEAD-box proteins are enzymes endowed with nucleic acid-dependent ATPase, RNA translocase and unwinding activities. The human DEAD-box protein DDX3 has been shown to play important roles in tumor proliferation and viral infections.
