As IgM and IgA-enriched preparations are needed to complete the immunotherapeutic spectrum, a simple procedure is described for the preparation of IgM and IgA enriched immunoglobulins. Fraction III which was prepared by cold ethanol fractionation was treated by octanoic acid followed by ethanol precipitation and ion-exchange chromatography using Sephadex DEAE A-50 and 0.1 M tris-D.35M NaCI ...

The perovskite-type oxides strontium-substituted lanthanum nickelate (LSNO) were prepared by a coprecipitation method in the present of octanoic acid as surfactant. The phase composition, morphology,lattice parameters and size of nanoparticles in these materials were characterized through Fourier transform infr...

Lyngbyabellin M is a non-ribosomal peptide synthetase/polyketide synthase derived metabolite isolated from the cyanobacterium M. bouillonii displaying thiazole rings and a distinct chlorinated octanoic acid chain. Its absolute configuration was proposed based on the comparison of its spectroscopic data with those of other representatives of this family of marine natural products, as well as deg...

      In the present study, four carbon sources were tested for the polyester synthesis of Pseudomonas aeruginosa PA01 which is a ubiquitous environmental bacterium and is one of the top three causes of opportunistic human infections. These included linear C8 to C11 carboxylic acids. Octanoic acid, nonanoic acid, decanoic acid and undecanoic acid were added to M1 ...

The present study assessed the possibility for the linoleic acid derivative 8-[2-(2-pentyl-cyclopropylmethyl)-cyclopropyl]-octanoic acid (DCP-LA) as an antiaging compound for the skin by assaying senescence-associated β-galactosidase (SA-β-Gal), a biomarker of senescence and cell viability. The nitric oxide (NO) donor sodium nitroprusside (SNP) increased in SA-β-Gal-positive cells in cultured h...
