Conjugated linoleic acids (CLA) are a group of linoleic acid isomers having double bonds in conjugated position, i. e. the double bonds are separated by one single bond. Two of the isomers: cis-9, trans-11 (c9, t11) and trans-10, cis-12 (t10, c12) CLA, have been shown to have biologically interesting properties. The c9, t11 CLA has been reported to have anticancer, antidiabetic and anti-inflamm...

BACKGROUND Conjugated linoleic acid (CLA) is a collective term for isomers of octadecadienoic acid with conjugated double-bond system. Thus, it was the objective to investigate whether milk composition and metabolic key parameters are affected by adding CLA to the diet of dairy cows in the first four weeks of lactation. METHODS A study was carried out with five primiparous cows fed a CLA supp...

N-dodecanoyl homoserine lactone (C12-HSL) was detected in the supernatant of an anammox granular sludge reactor (AGSR). C12-HSL could enhance the specific anammox activity of anammox biomass. Adding C12-HSL-containing AGSR supernatant into the continuously stirred tank reactors reduced the start-up time of the anammox process from 80 to 66days. Moreover, the nitrogen loading rate was also enhan...

An emissive terbium complex has been conjugated to a C12 chain, Lys-Arg7, Arg7, a tetraguanidinium cation and human serum albumin; two-photon excitation at 720 nm facilitated microscopy studies revealing cell localisation profiles with the oligo-guanidinium conjugate localising in mitochondria but causing apoptotic cell death (IC(50)12 microM), the C12-amide complex giving rise to necrotic cell...

beta-Carotene ethenolysis under promotion of well-defined ruthenium catalysts were examined as a novel method of synthesis of vitamin A derivatives. Efficient reaction was promoted by the second-generation Hoveyda catalyst. The products of ethenolysis in positions C15-C15', C11-C12, and C9-C10 were detected, but cleavage of the C11-C12 double bond predominated. Even better regioselectivity at t...
