PeerJ. 2015 May 19;3:e902. doi: 10.7717/peerj.902. eCollection 2015.

The current commercial production protocols for Atlantic cod depend on enriched rotifers and Artemia during first-feeding, but development and growth remain inferior to fish fed natural zooplankton. Two experiments were conducted in order to identify the underlying factors for...

Fatty acid analyses of sperm and erythrocyte cell membrane phospholipids in idiopathic infertile patients evidenced that erythrocyte contents of EPA, DHA, omega-6-omega-3 ratio and arachidonic acid provide a mathematical correspondence for the prediction of EPA level in sperm cells....

Encapsulation efficiency of CdSe/ZnS quantum dots by liposomes determined by thermal lens microscopy.

Biomedical optics express

Batalla J, Cabrera H, San Martín-Martínez E, Korte D, Calderón A, Marín E.

Biomed Opt Express. 2015 Sep 10;6(10):3898-906. doi: 10.1364/BOE.6.003898. eCollection 2015 Oct 01.

In this study the encapsulation of core shell carboxyl CdSe/ZnS quantum dots (QDs) by phospholipids liposome complexes is presented. It makes the quantum dots water soluble and photo-stable. Fluorescence self-quenching of the QDs inside the liposomes was observed. Therefore,...

Formation of complex organic molecules in methanol and methanol-carbon monoxide ices exposed to ionizing radiation--a combined FTIR and reflectron time-of-flight mass spectrometry study.

The radiation induced chemical processing of methanol and methanol-carbon monoxide ices at 5.5 K exposed to ionizing radiation in the form of energetic electrons and subsequent temperature programmed desorption is reported in this study. The endogenous formation of complex...

Interaction of a phosphatidylcholine derivative of 1,6-diphenyl-1,3,5-hexatriene (DPH) with intact living cells: Steady-state fluorescence polarization and phase fluorometry studies.

Journal of fluorescence

Na(+), K(+), Mg(++)-activated adenosine triphosphatase and K(+), Mg(++)-activatedp-nitrophenyl phosphatase prepared from a membrane fraction of bovine cerebral cortex were studied with regard to the manner of their activation by phospholipids, using phosphatidyl serine, lysolecithin, monodecyl and didecyl phosphates. The...
