We evaluated the effects of dietary lipid class (phospholipid vs. neutral lipid) and level of n−3 long-chain PUFA (LC-PUFA) on the growth, digestive enzymatic activity, and histological organization of the intestine and liver in European sea bass larvae. Fish were fed from the onset of exogenous feeding at 7 to 37 d post-hatch with five isoproteic and(More)
Human intestinal epithelial cell survival and anoikis are distinctively regulated according to the state of differentiation. In the present study, we analyzed the roles of focal adhesion kinase (Fak)/Src signaling to the PI3-K/Akt-1 and mitogen-activated protein kinase (MEK)/extracellular regulated kinases (Erk) pathways, within the context of such(More)
Coordinate production of interleukin-1 beta (IL-1 beta) and granulocyte macrophage-colony stimulating factor (GM-CSF) or IL-6 by the blast cells of acute myeloblastic leukemia (AML) and normal peripheral blood leukocytes have been previously reported (van der Shoot et al.: Blood 74:2081-2087, 1989; Bradbury et al.: Leukemia 4:44-47 1990a, British Journal of(More)
Acute myeloblastic leukemia (AML) blasts have been shown to produce a variety of cytokines in culture such as interleukin-1 (IL-1), IL-6, granulocyte-, macrophage-, and granulocyte-macrophage colony-stimulating factor (GM-CSF), and tumor necrosis factor-alpha (TNF alpha). Using two sensitive and specific enzyme-linked immunosorbent assays for IL-1 beta and(More)
Our aim was to quantify the degree of association that selected psycho-social and health variables have with psychological distress in the elderly. In order to estimate the level of association, data previously obtained from the "Enquêre Santé Québec" (1987) were entered into a multiple regression analysis with psychological distress as the dependent(More)
Experiments were performed to investigate the role of adherent (A) cells in graft-versus-host (GVH)-induced immunosuppression. GVH reactions (GVHR) were induced in adult F1 hybrid mice by intravenous injections of parental lymphoid cells. Spleen cells (SC) from mice experiencing a GVHR (GVH mice) were stimulated with phytohaemagglutinin (PHA), concanavalin(More)
