Tendência na Produção Científica em Estudos de Citogenética em Canídeos: Uma Abordagem Cienciometrica.

Abstract

Cytogenetics arises to study the nature of chromosomes, divided into two areas, the classical based on chromosomal bundles and the molecular-based fluorescence probes. Cytogenetics in dogs has made great strides in recent years due to research interests in the investigation of hereditary diseases mainly in the area of oncology. The objective of this dissertation was to evaluate the trend of scientific publications on cytogenetics of canids using the Web of Science database by means of cienciométrica analysis. Data were obtained through the ISI Web of Science platform from 1974 to 2018 using the words "canids", "cytogenetics" and "chromosomes" as search terms. The selected atlases were collected data and made quantitative analyzes and fisher exact tests and Spearman correlation. Data were tabulated and analyzed using descriptive statistics. 210 articles were selected from 1974 to 2018, with 2011 being the year with the most publications. The United States followed by Poland were the countries with the highest number of authorships accounting for 35% of the publications. The number of authors per article varied from 1 to 20 and Switonski M. was the author with more publications. Looking at the co-authorships and authorships, we have Pozan University as the largest collaborator in this area and England the country with the most publications. About 1384 keywords were used and of these the word Dog was used in 8.2% of the articles. Among the canids studied, domestic dogs were more expressive used as methodology in 79% of the articles. Of these 42% were SRD and among the dogs of race the highlight was for the Beagle breed in 5.9% articles. Among the cytogenetic methods used by the authors, the FISH technique was the most used in 40.2% of the works followed by karyotyping technique (28.4%) and banding (24.5%). 21.4% of the articles dealt with problems in the area of canine oncology being the most expressive area observed. The number of studies in the area of cytogenetics in dogs is still small, but the similarity between these animals and humans, makes more and more research to find answers to human cancers using the model dogs.
