Feed additives can differentially modulate NF-κB (RelA/p65), IGF-1, GLUT2, and SGLT1 gene expression in porcine jejunal explants R. Bras. Zootec.

ABSTRACT The intestinal gene expression of RelA/p65 (NF-κB), insulin growth factor 1 (IGF-1), glucose transporter 2 (GLUT2), and Na+/dependent glucose transporter 1 (SGLT1) were evaluated in response to benzoic acid, yeast culture, L-glutamine, and oregano essential oil, using an ex vivo model. Six piglets weighing approximately 20 kg each were sacrificed, and their jejunum was collected and segmented into five 2-cm explants. Each explant was immersed in cell culture medium according to one of the following treatments: control (without additive), 0.5% benzoic acid, 1% yeast culture, 1% L-glutamine, and 0.015% oregano oil. Gene expression was evaluated using RT-PCR. Yeast culture up-regulated the gene expression of RelA/p65, IGF-1, GLUT2, and SGLT1 in...

First Steps of in Situ Surface-Enhanced Raman Scattering During Shipboard Experiments ArchiMer
Peron, Olivier; Rinnert, Emmanuel; Colas, Florent; Lehaitre, Michel; Compere, Chantal.
It is shown that the surface-enhanced Raman scattering (SERS) technique can be applied to detect organic molecules during in situ experiments. To this purpose, we used trans-1,2-bis(4-pyridyl)ethylene (BPE) as a target molecule. Adsorbed on the SERS chemosensor surface and excited under laser, the vibration modes of the molecules can be identified. SERS chemosensors are based on quartz substrates functionalized by silanization and partially coated with gold nanoparticles. SERS measurements during shipboard experiments were made with a home-made in situ Raman spectrometer connected to a marinized micro-fluidic system. The device was designed to host chemosensors in order to ensure measurements with a flow cell. A theoretical limit of detection was estimated...
