Glycoconjugate characterization in the intestine of Umbrina cirrosa by means of lectin histochemistry
No full textGoblet cells in the intestine of shi drum Umbrina cirrosa showed the presence of glycoconjugates particularly rich in fucose and N‐acetylglucosamine residues. They displayed also sialic acid linked to galactosyl(β1→3)N‐acetylgalactosamine and to galactosyl(β1→4)N‐acetylglucosamine. All the nine horseradish peroxidase‐conjugated lectins employed with the only exception of GSA II marked the enterocytes supranuclear region and the cell coat; the cell coat showed a more intense reactivity toward the different lectins, particularly enhanced with the use of fucosyl specific lectins

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
