Glucagon-like peptide-1 does not have specific, high-affinity receptors on rat liver membranes, does not displace glucagon from glucagon receptors on these membranes and does not stimulate the production of cyclic AMP by isolated rat hepatocytes. In the presence of glucagon, high concentrations of glucagon-like peptide-1 do not significantly alter the(More)
In a previous work, the shape of Arabidopsis seed was described as a cardioid modified by a factor of Phi. In addition, J index was defined as the similarity of the seed (in an orthogonal, bi-dimensional image) to a cardioid, thus allowing the quantitative comparison of seed shape in seeds of varieties and mutants at different stages of development. Here, J(More)
In rodents, diabetes mellitus is accompanied by a decreased concentration of epidermal growth factor (EGF) in plasma and urine and by a reduced number of EGF receptors on the surface of target cells. A combination of these two abnormalities may reduce the effects of EGF and could be implicated in some complications of diabetes. The aim of the present work(More)
