Publication date: 15 June 2019Source: Journal of Molecular Liquids, Volume 284Author(s): Jagar A. Ali, Kamal Kolo, Abbas Khaksar Manshad, Karl D. StephenAbstractPolymer and low-salinity water flooding have been shown, repeatedly, to be effective methods for chemical Enhanced Oil Recovery (cEOR). The benefits are obtained by increasing the viscosity of the injected fluid, minimizing the interfacial tension (IFT) of the crude oil/aqueous phase, and by wettability alteration. Similarly, nanofluids (fluids injected with nanoparticles) have also been demonstrated to induce the same processes. We have analyzed the EOR response o...

ConclusionsIRW, an egg-derived small bioactive peptide enhances osteoblastic activity and stimulates osteogenesis. The stimulation is primarily due to the activation of PI3K-Akt-RUNX2 pathway and its downstream effectors, accompanied by a secondary collagen synthesis pathway.General significanceOur results revealed the positive effects of tripeptide IRW on regulating osteogenesis and collagen synthesis, indicating its potential for the prevention or treatment of osteoporosis.Graphical abstract

Publication date: Available online 18 April 2019Source: Nitric OxideAuthor(s): Fabian Gather, Katja Schmitz, Kathrin Koch, Lea-Marie Vogt, Andrea Pautz, Hartmut KleinertAbstractThe human inducible nitric oxide synthase (iNOS) gene contains an upstream open reading frame (uORF) in its 5′-untranslated region (5′-UTR) implying a translational regulation of iNOS expression. Transfection experiments in human DLD-1 cells revealed that the uORF although translatable seems not to inhibit the translation start at the bona fide ATG. Our data clearly show that human iNOS translation is cap-dependent and that the 5&prime...

FabrizioAbstractEfficient protection against degradation process of tetrahedrite-based thermoelectric materials was obtained employing AlTiN based thin films. The coatings were deposited via reactive direct current physical vapour deposition magnetron sputtering. The composition, thermal and electrical behaviour of thin films were investigated by X-ray diffraction, energy dispersive spectroscopy associated to field emission scan...

The gellation of the β-ChNFs dispersion was achieved through a dialysis neutralization process, and hydrogels, even at 0.2% solid content, had high stiffness, as indicated by the dynamic viscoelasticity measurements. The β-ChNFs hydrogels were used as scaffolds to fabricate ultra-small sil...
