    Arthropod phylogeny: onychophoran brain organization suggests an archaic relationship with a chelicerate stem lineage

    Apr 28, 2006 - Neuroanatomical studies have demonstrated that the architecture and organization among neuropils are highly conserved within any order of arthropods. The shapes of nerve cells and their neuropilar arrangements provide robust characters for

    Formation of biologically active peptides

    Oct 29, 1980 - Many small biologically active peptides are derived from larger precursor forms which fulfil a variety of roles in the synthesis, segregation and intracellular migration of secretory products. Limited proteolysis may occur at several stages during

    Photocontrol of extension growth: a biophysical approach

    Oct 18, 1983 - The analysis of plant growth as a physical process is briefly reviewed. Growth requires the coordinated uptake of water and the irreversible expansion of the cell wall. Any agent that affects the growth rate must act on one or more of the parameters

    Control of ripening

    Nov 29, 1993 - Ripening of fleshy fruits involves major changes in physiology and biochemistry that alter their colour, flavour, texture, aroma and nutritional value. These changes affect all cell compartments and require the expression of new genes encoding

    Bone marrow transplantation and approaches to avoid graft-versus-host disease (GVHD)

    Aug 16, 2005 - Haematopoietic stem cell transplantation (HSCT) offers promise for the treatment of haematological and immune disorders, solid tumours, and as a tolerance inducing regimen for organ transplantation. Allogeneic HSCTs engraftment requires

    The dynamics of genetic control in the cell: the good and bad of being late

    Sep 28, 2013 - The expression of genes in the cell is controlled by a complex interaction network involving proteins, RNA and DNA. The molecular events associated with the nodes of such a network take place on a variety of time scales, and thus cannot be regarded

    Seasonal variation in nutrient utilization shapes gut microbiome structure and function in wild giant pandas

    Sep 13, 2017 - Wild giant pandas use different parts of bamboo (shoots, leaves and stems) and different bamboo species at different times of the year. Their usage of bamboo can be classified temporally into a distinct leaf stage, shoot stage and transition stage.
