No full textEffect of NADH on the redox state of human hemoglobin
No full textIn this work, we report that NADH can increase the autoxidation rate of hemoglobin (HbA) in a pH-dependent fashion. During this process, this cofactor is itself oxidized. The presence of superoxide dismutase (SOD) and/or catalase (CAT) can inhibit this result. At lower pH rates, the effect of NADH on the hemoglobin autoxidation rate is more enhanced; in addition, the rate of NADH oxidation is increased. Our data indicates that the reduced pyridine nucleotide may influence the redox state of human hemoglobin by a mechanism, which probably involves free radical species

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
