The L1 cell adhesion molecule promotes neurite outgrowth and neuronal survival in homophilic and heterophilic interactions and enhances neurite outgrowth and neuronal survival homophilically, i.e. by self binding. We investigated whether exploitation of homophilic and possibly also heterophilic mechanisms of neural stem cells overexpressing the full-length transmembrane L1 and a secreted trimer...

Wild lowbush blueberry fields are characterized by high genetic diversity, with a large number of genotypes coexisting in every field. Yield also varies among genotypes, which could be related to the variation physiological and structural traits, but this has not been rigorously tested. In study, we aimed quantify inter-genotype yield, as well leaf stem functional establish relationship between...

Crimson clover (Trifolium incarnatum L. convar. Inkara) seeds were imbibed with water solution of various pH values (4, 5, 6 and 7) at ambiental temperatures (10, 15 22 °C) the aim to reveal treatments effects on seed (imbibition, germination energy, electric conductivity) seedling traits (stem, root total length). Seeds in a laboratory by standard method for germination. When averaged over inq...

The stem xylem conduit dimensions and hydraulic conductivity of chrysanthemum plants (Dendranthema x grandiflorum Tzvelev cv. Cassa) were analysed and quantified. Simple exponential relations describe conduit length distribution, height dependency of conduit length distribution, and height dependency of stem hydraulic conductivity. These mathematical descriptions can be used to model the xylem ...

tuberose (polianthes tuberosa l.) is one of the most important cut flowers in tropical and subtropical areas. this flower has forth order in cut flower and second order in bulbous plants production in iran. plant spacing and nitrogen necessity are the most important factors for tuberose quality and quantity. in this study, field experiment carried out as factorial design in randomized complete ...

Recognition of the growing role of human mesenchymal stem cells (hMSC) in tissue engineering and regenerative medicine requires a thorough understanding of intracellular biochemical and biophysical processes that may direct the cell's commitment to a particular lineage. In this study, we characterized the distinct biomechanical properties of hMSCs, including the average Young's modulus determin...

BACKGROUND Proximal femoral bone loss during revision hip arthroplasty often requires bypassing the deficient metaphyseal bone to obtain distal fixation. The purpose of this study was to determine the effect of stem diameter and length of diaphyseal contact in achieving rotational stability in revision total hip arthroplasty. METHODS Twenty-four cadaveric femoral specimens were implanted with...
