The energy dependence of hadron production in relativistic nucleus-nucleus collisions reveals the anomalies. They were predicted as signals deconfinement phase transition and observed by NA49 collaboration Pb + at CERN SPS. This indicates onset central about 30 AGeV.

this study has examined the functional importance of nucleus accumbens (nac)-ventral tegmental area (vta) interactions. as it is known, this interaction is important in associative reward processes. under urethane anesthesia, extracellular single unit recordings of the shell sub-region of the nucleus accumbens (nacsh) neurons were employed to determine the functional contributions of the vta to...

agrobacterium tumefaciens is capable of gene transfer to both plant and non-plant organisms. indeed, upon infection of eukaryotic cells, agrobacterium tumefaciens transfers a piece of its tumor inducing (ti)-plasmid, called t-dna, to the host cell nucleus, which subsequently integrates into the host genome. the vird2 virulence protein which has relaxase endonuclease activities covalently binds ...

in many models of programmed cell death, the mitochondrial protein aif translocates to the nucleus, where it induces the chromatin condensation and dna degradation. however, today it is well established that this flavoprotein is bifunctional. in addition to its lethal function in the nucleus of dying cells, aif plays a vital bioenergetic role in healthy ones by regulating mainly the activity of...

Introduction: Previously, we demonstrated that i.p. injection of aqueous extract prepared from aerial parts of Drosera Spatulata (Droseraceae) can induced remarkable analgesia in both phases of formalin test in rats. Because, analgesia induced in acute phase of formalin test mainly mediated by activation of central analgesic mechanisms and also paragigantocellularis (PGi) nucleus is part of bra...
