The goal of this study was to analyse the defence mechanism's changes during adolescent's adaptation to the new schooling terms at the first year in high school. Sample of 266 students, mean age 15, have been included in the research. Kellerman's Life Style Questionnaire (LSQ) was administred for measuring defence mechanisms at the beginning and at the end of the school year. Results show that ...
Plant leaf senescence and defence responses are important biological processes, but the molecular mechanisms involved are not well understood. This study identified a new rice mutant, spotted leaf 29 (spl29). The SPL29 gene was identified by map-based cloning, and SPL29 was confirmed as UDP-N-acetylglucosamine pyrophosphorylase 1 (UAP1) by enzymatic analysis. The mutant spl29 lacks UAP activity...
within the genome and lacks the antibody production that characterizes the adaptive immune response of higher vertebrates. The insect innate immune system is capable of recognition and subsequent eradication of microbes and multicellular parasites through humoral and cellular defence mechanisms (reviewed in Lemaitre and Hoffmann, 2007). Humoral immunity is mediated by production of microbicidal...
The first encounter of the neonate with Esch. coli consists of the normal intestinal colonization. Already at this stage the body is able to cope with these micro-organisms, accepting them as a part of the normal intestinal flora, but hindering them from invading the tissues. It is obvious, however, that from this early colonization onward the infant and then the child is carrying a reservoir o...
Environmental pollution, increasing CO2 atmospheric levels and the greenhouse effect are closely associated with ongoing climate change extreme climatic events we witnessing all over Earth. Drought, high temperature salinity among main environmental stresses that negatively affect yield of numerous crops, challenging world food safety. These effects more profound in vegetable crops which genera...
