Progress of the Journal of the Balkan Union of Oncology in the second decade of its existence.

Purpose: To investigate the progress of the Journal of the Balkan Union of Oncology (JBUON) in the second decade of its existence.

Methods: We investigated 10 volumes of JBUON, consisting of 42 issues, with regard to the number and category of articles, the contribution of authors from Balkan and non-Balkan countries, and the (co)authorship in published articles.

Results: In period 2006-2015, 1407 articles of different categories were published in JBUON.

Importance of being indexed in important databases--effect on the quantity of published articles in JBUON.

Purpose: To investigate the dynamics of indexing the Journal of the Balkan Union of Oncology (JBUON) in important biomedical databases, the effects on the quantity and type of published articles, and also the countries of the (co)authors of these papers.

Methods: The process of the JBUON indexing started with EMBASE/Excerpta Medica, followed in 2006 (PUBMED/MEDLINE) and continued every second year in other important biomedical databases, until 2012 when JBUON became Open Access Journal (for even more information please visit www.jbuon.

Multiauthorship and false authorship: why worrying about this?

Authorship and authorship abuse are in the focus of interest of all main actors in the publication game--authors, reviewers and editors of scientific journals. Along with the steady rise of the number of publications, the number of coauthors in multiauthored papers raises even more, some of them being undeserved authors. Because publication is the main way for evaluating scientists, authorship is prone to abuse, and thus the false/undeserved/gift authorship emerges.

Effects of a short-term differently dosed aerobic exercise on maximum aerobic capacity in breast cancer survivors: a pilot study.

Background/aim: Regular physical activity and exercise improves quality of life and possibly reduces risk of disease relapse and prolongs survival in breast cancer survivors. The aim of this study was to evaluate the impact of a 3-week moderate intensity aerobic training, on aerobic capacity (VO2max) in breast cancer survivors.

Methods: A prospective, randomized clinical study included 18 female breast cancer survivors in stage I-IIIA, in which the primary treatment was accomplished at least 3 months before the study inclusion.

[Fraud in biomedical literature].

The basic ethical principles in science are internationally recognised in all disciplines of science. The first among these is honesty--both towards oneself and towards others. The betrayal of this principle can be seen as deviant behaviour, which may result in the most serious violation of the high ethical standards of science--scientific fraud.
