“Proliferation activity in oral cutaneous canine melanocytic tumours: correlation with histological parameters, location and clinical behaviour”
No full textA total of 62 canine melanocytic tumours (10 melanocytomas and 52 primary malignant melanomas) were investigated to compare the accuracy of prognosis provided by MIB-1 proliferation index (MIB-1-PI) with classical histological criteria and location. MIB-1-PI was assessed by means of quantitative image analysis of sections immunostained with MIB-1 monoclonal antibody. Tumour location, histological cell type, stromal or lymphatic vessel invasion, maximum tumour thickness, and presence of inflammation or necrosis were recorded for each case. Thirty-eight dogs were submitted to a 1-year follow-up and the clinical outcome of the disease determined. MIB-1-PI in melanocytomas differed significantly from that detected in primary malignant melanomas (P = 0.0001). A significant difference in MIB-1-PI was revealed between oral and cutaneous malignant melanomas (P = 0.015), and between presence and absence of lymphatic vessel invasion (P = 0.05). MIB-1-PI was not correlated with the other parameters. In univariate analysis, only tumour location (oral vs cutaneous), presence of lymphatic vessel invasion, and MIB-1-PI were associated with decreased overall survival (P = 0.0001, P = 0.0144, and P = 0.0489, respectively). In conclusion, the results of our study confirm that the assessment of the MIB-1-PI may be of additional prognostic value for dogs with primary malignant melanomas

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
