Perforin and Fas/FasL cytolytic pathways at the maternal-fetal interface.

Abstract: The immunogenetic enigma of maternal acceptance of the fetal semial-lograft has been termed an immunological paradox. The first trimester decidua is heavily infiltrated with CD56 b r i g h t CD16 - uterine natural killer (uNK) cells which must be prepared to respond to potential pathogen challenges and still be able to control immune responses that allow the development of the fetus. The significant presence of cytolytic mediators, perforin and Fas/Fas ligand (FasL), at the maternal-fetal interface raises a question of their role(s) in the immunological interrelations between maternal tissues and trophoblast cells. As uNK cells in vitro lyse target cell lines (K562, P815 and P815Fas) using these effector molecules, it seems that, although immunocompetent, their cytotoxicity is not directed against trophoblast during normal pregnancy. Therefore, it is generally believed that the hormonal and Thl/Th2 cytokine balance plays an important role in the tolerance and maintenance of pregnancy. This paper gives an overview of the recent findings on the complex immunological events that occur at the maternal-fetal interface.

Cultural influences on motives for organic food consumption

Abstract: Purpose – The purpose of this paper is to test whether differences in motives for healthy food consumption stem from differences in cultural dimensions and whether cultural dimensions could serve as predictors for health food consumption motivationsDesign/methodology/approach – The study correlated secondary data on motives for healthy food consumption in a number of West European countries to cultural dimensions of those countries In addition, primary data for prime motives of healthy food consumption were collected for Croatian consumersFindings – Influence of cultural dimensions was partly confirmed and that only for individualism and assertiveness, while human orientation and uncertainty avoidance showed no correlation to organic food consumption motivation Croatian consumers display homogeneous collective awareness, ie they almost exclusively consider health as prime consumption motiveResearch limitations/implications – Correlation analysis was conducted on a small data set; the units of analy

An Analysis of Combined Cyclic Heat Treatment Performance

Abstract: The strengthening of AISI 4140 steel by cyclic heat treatment has been investigated. The applied cyclic heat treatment was consisted of both, temperature cycling with diffusional transformation and double quenching with diffusionless transformation. Both, temperature cycling and second quenching increase yield strength and Charpy-V toughness as measures of steel strength and toughness. The increase of yield strength and Charpy-V notch toughness are directly in relation of structure fineness. Much better mechanical properties are obtained by the appropriate cyclic heat treatment than by the quenching and tempering of steel AISI 4140.
