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
Aspartate aminotransferase activity in peri-implant mucositis: experimental peri-implant mucositis model of 14 days
No full textBACKGROUND: Experimental pen-implant mucositis has been studied from various prospective in a duration of 21 days. Given the higher sensitivity of pen-implant mucosa the aim of the present study was to evaluate if a duration of 14 days would be sufficient to establish a state of measurable inflammation. METHODS: Twenty patients of age 57 11-year-old contributed with 20 clinically healthy implants and teeth. They were instructed to use an individual stent in the selected elements prior to performing oral hygiene for 14 days. For each element plaque index (P11), probing depth (PD), bleeding on probing (Bops) were reported at 0 days and 14 days of plaque accumulation. Aspartate aminotransferase activity was measure at both time points from the crevicular fluid. RESULTS: Both implant and teeth developed similar increased response of inflammation at 14 days compared to day 0: BoPs of 4.2+1.8 (P 0.06) and BoPs of 3.1+2.2 (P 0.048) for implant and tooth, respectively. Implant presented deeper pocket depth at both time periods but less plaque accumulation. AST activity did not increased significantly, but it was significantly higher at implant level
