Use of bovine lymphocytes to assess the immunomodulatory effect of natural extracts

A simple and rapid method based on the in vitro bovine lymphocyte proliferation was developed to assess the immunomodulatory activity of natural compounds extracted from plant and foods. The proliferation of lymphocytes was measured by the MTT [3-(4, 5- dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide] assay. This test was used to measure the immuno-enhancing activity of 2 plant extracts and 2 samples of fermented milk after 48 h of incubation. To evaluate the effect of the cow physiological phase on the assay response, the tests were repeat- ed using lymphocytes taken from non-pregnant dry, pregnant dry and post partum cows. The assay was not affect- ed by the cow physiological phase and the results obtained were comparable. Both plant extracts enhanced lym- phocyte growth, in particular the extract 2 was slightly more potent than extract 1. The fermentation of milk with proteolytic starter cultures, such as FAIR E-63 and LA 2, can generate peptidic compounds from milk protein with potential immunostimulating activity. These samples tested in cell culture inhibited lymphocyte proliferation because they showed an acidic pH of 4.5. However, this bioassay was enough sensitive to detect biological activity of different compounds also at low concentrations

Signatures of multiphonon and neutron transfer couplings in the fusion of S36,32+Pd110

Fusion-evaporation cross sections have been measured for S-32,S-36+Pd-110 to high accuracy in the energy range around the Coulomb barrier. The two extracted fusion barrier distributions display very similar structures with two well-resolved peaks below the nominal barrier, which are consistent with a model calculation including the coupling of the one-, two-, and three-phonon collective vibrations of Pd-110. A third lower-energy barrier, together with a strong relative cross section enhancement, is observed for S-32+Pd-110 and is reproduced by coupling the two-neutron pickup channel which has a large and positive ground state Q value (+5.1 MeV). For S-36+Pd-110, the calculated effect of the corresponding transfer channel (with negative Q value) is much smaller

Fusion of 40Ca+124Sn around the Coulomb barrier

Fusion-evaporation cross sections of View the 40Ca + 124Sn have been measured with good precision and the barrier distribution extracted, following a complementary experiment on multinucleon transfer on the same system. The completeness of the data allows to constrain the fusion calculations concerning the effect of transfer coupling. The measured cross sections are strongly enhanced below the barrier compared to the one-dimensional barrier penetration estimate and the “barrier distribution” is broad with no clear peak structure. Those features, together with transfer Q-values and cross sections make this system very similar to View the 40Ca + 96Zr where there were also hints of significant transfer effects. Simplified coupled-channel calculations fail to reproduce the low energy tail of the data, although the barrier distribution is qualitatively reproduced. At a few energies, also the fusion of View the 40Ca + 116Sn has been measured and found to be very similar to the 124Sn case
