Brazilian medical publications: citation patterns for Brazilian-edited and non-Brazilian literature
Cunha-Melo, J.R.;Santos, G.C.;Andrade, M.V.;
Brazilian Journal of Medical and Biological Research , 2006, DOI: 10.1590/S0100-879X2006000800001
Abstract: today, the quality of a scientific article depends on the periodical in which it is published and on the number of times the article is cited in the literature. in brazil, the criteria for the evaluation of this scientific production are improving. however, there is still some resistance, with authors arguing that brazilian publications must be preferentially addressed to the national readers and, therefore, they should ideally be written in portuguese. in order to determine the kind of scientific journals cited in the reference lists of articles published in medical periodicals edited in brazil, in the present study we determine the rate of portuguese/english citations. three issues of 43 periodicals (19 indexed in scielo, 10 in pubmed, 10 in lilacs, and 4 in the isi-thompson base) of different medical specialties were analyzed, and the number of both portuguese and english citations in the reference list of each article was recorded. the results showed that in brazilian-edited journals the mean number of citations/article was 20.9 ± 6.9 and the percentage of citations of international non-brazilian periodicals was 86.0 ± 11.2%. of the latter, 94.4 ± 7.0 are indexed by isi-thompson. therefore, we conclude that brazilian medical scientists cite the international non-brazilian periodicals more than the national journals, and most of the cited papers are indexed by isi-thompson.
Determina??o da raz?o ótima de espermatozóides por ovócitos de piabanha Brycon insignis (pisces - characidae)
Shimoda, E.;Andrade, D.R.;Vidal Júnior, M.V.;Godinho, H.P.;Yasui, G.S.;
Arquivo Brasileiro de Medicina Veterinária e Zootecnia , 2007, DOI: 10.1590/S0102-09352007000400009
Abstract: the optimum spermatozoa:oocyte ratio of piabanha brycon insignis was studied. two males and two females were induced to spawn, and the gametes were stripped after 200 hourgrades starting from the application of carp pituitary gland. oocytes from two females were mixed, and samples of 2g (701 oocytes/g) were collected from the obtained pool and placed into plastic cups. the semen from the two males, after mixed to compose a pool, was diluted in nacl solution (1.2%) so that, after the addition of 1ml of diluted sperm into the oocytes, the following spermatozoa:oocyte ratios (tri-replicated) were obtained: t1=86,662, t2=173,324, t3=259,986, t4=346,648 and t5=433,310. after the activation using 1% nahco3 and fertilization, the eggs were transferred to incubators, and observed the percentages of fertilization relative to the control. t1=35.7%, t2=53.1%, t3=79.1%, t4=93.4% and t5=87.8%. undiluted semen was used as "control", which showed 65% of fertilization. the percentage of fertilization (relative to the control) increased linearly according to the regression y= 15.55 + 0.0002297x (p<0.01; r2=0.98), until the proportion of 314,481 spermatozoa per oocyte, and, from this point, the fertilization rate maintained at 88%.

M.V. Sprindzhuk
Sovremennye Tehnologii v Medicine , 2010,
Abstract: Aim of investigation is establishment of the lethal thrombosis and attendant complication development reasons and mechanisms after operations of the univentricular heart hemodynamic correction: a high significance of pressure in a pulmonary artery prior to operation, execution of multiple operations and, particularly, the pulmonary artery stenosis operations, a complicated anatomy of disease and attendant anomalies of development, and a bronchopulmonary pathology.Materials and methods. The case histories from the infantile surgical center, the Cardiology RSPC infantile age cardiosurgery department archives were a subject of investigation; a retrospective analysis is made.

Abstract: The questions of the heart single ventricle correction operation modification elaboration history, detection of indications to the Fontain’s operation execution are highlighted. The principles of the Fontain’s circulation, conditions of effective and the risk factors of operations, their influence on the proximate and remote results of operative intervention, are discussed.
DYNAMICS OF NUMBER OF GREY HERONS (ARDEA CINEREA L.) COLONY IN THE UPPER COURSE OF ZAPOROZHYE (DNEPROVSKOYE) RESERVOIR
Vovk M.V.
Bìologì?nij Vìsnik Melìtopol?s?kogo Der?avnogo Pedagogì?nogo Universitetu ìmenì Bogdana Hmel?nic?kogo , 2012,
Abstract: The research was performed in the area of natural reserve "Dneprovsko-Orelsky" and its adjacent territory – the island Pogorely. We discovered the changes of number of grey heron in colonial settlements, determined the principal factors influencing the formation of spatial structure of island bird communities. The analysis of nest distribution towards tree breeding biotopes was performed and stability of spatial structure of bird colonies was proved. We were tracking the number dynamics of pioneer colony and revealed the principal ecological and anthropogenic factors influencing the fluctuation of its abundance.
SPECIES DIVERSITY AND STABILITY OF BIRD COMMUNITIES

Abstract: When comparing the suggested stability indicators, we obtained statistically significant correlations for indicators of annual stability of species and total number and standard deviation of the logarithm of the number. Annual Stability Index can be applied with a high degree of reliability as a characteristic of the averaged structure of the community and its pyramid of abundances. The results of correlation analysis confirm our assumptions about the correlation between stability over the years and indices of species diversity and relative uniformity.The final task of the study was to create a mathematical model of stability, where the independent variables are the indices of species diversity. The calculation of these indices allows forecasting birds’ community stability. According to the result of multiple regression for the indicators of diversity and stability of the breeding birds’ community highest correlation coefficients were obtained fro Shannon index and Simpson's dominance Index.Community stability could be determined by its overall species diversity. When considering the stability of community its diversity should be considered as a combination of uniformity of their total number and number of species. The most suitable predictors for the community stability were the nonparametric index of dominance and information-statistical indices, since they considered simultaneously evenness and richness. The community stability is subject of the complexity of its internal communications pattern.
