Research into the accumulation patterns of protein oxidative modification (POM) products and lipids in Crohn’s disease (CD) and ulcerative colitis (UC) could have important implications for understanding the pathogenesis and improving the diagnosis and therapy for these diseases. The aim of this study was to investigate the aspects of free radical oxidation (FRO) in the large bowel and their possible correlations with clinical symptoms of UC and CD. In the Wistar rat model used in the experiment, CD was induced with 2,4,6-trinitrobenzenesulfonic acid, and UC was induced with oxazolone. Clinical status was assessed using the Disease activity index (DAI). Lipid peroxidation (LPO) products were measured in the heptane and isopropanol phases of the intestinal mucosa extract. POM products were measured following spontaneous and stimulated oxidation. The DAI ( Me (Q25–Q75)) was increased in both CD and UC on days 3 and 7 of the experiment: for CD, it was equally increased on days 3 and 7 (7 (3-7)) and was 11 (11–11) and 11 (9–11) for UC on days 3 and 7, respectively. The amount of primary, secondary and end LPO products in the heptane and isopropanol phases, as well as the total amount of POM products, was increased in the homogenized mucosa of the large bowel. In the CD group, the relative content of secondary basic POM products was increased on day 7 of the experiment. The following patterns of FRO were revealed: accumulation of LPO products in the UC group and accumulation of POM products in the CD group; UC is characterized by the accumulation of mostly LPO products in the heptane phase and secondary LPO products in the isopropanol phase; CD is characterized by the accumulation of secondary basic POM products. DAI scores were correlated with the amount of LPO products in the isopropanol phase and the amount of POM products in the spontaneous oxidation mode. The highest number of strong correlations was observed in the UC group. Our findings suggest a very serious contribution of FRO changes to the pathogenesis of UC and CD, meaning that LPO and POM products could be regarded as diagnostic markers and indicators of treatment efficacy.

Modern papers on treatment and rehabilitation of stroke patients describe the advantages and effectiveness of certain medical rehabilitation types, but these data are not enough to evaluate the efficiency of the whole rehabilitation system. The study was aimed to investigate the potential of the patient-centered problem-oriented multidisciplinary three-stage system for medical rehabilitation of stroke patients. Thestudyincluded 1021 patientsover 18 affected with ischemic or hemorrhagic stroke in the acute phase. All patients had a disability of admission at the time (but no persisting disability in their history). Two models of rehabilitation measures were compared in two consecutive phases of the study. The linear model of rehabilitation assistance was mainly implemented in phase 1, and the multidisciplinary model was implemented in phase 2. The patients’ condition was evaluated using the Modified Rankin Scale (mRS) at the end of rehabilitation. Comparison of the 1st and 2nd phase results demonstrated that the number of patients with mRS score 0–1 in the 2nd phase was lower by 18%. The proportion of patients with positive dynamics was significantly higher in the 2nd phase than in the 1st phase, (16 and 30% respectively). In the 2nd phase there were significantly more patients who demonstrated improvement by 1–4 (mRS score). Thus, the use of a multidisciplinary model provides a significant benefit compared with a linear rehabilitation model.

Dear researcher!
At the end of 2015, Bulletin of RSMU saw an important change in its typographic design and content. We formulated new editorial policies and established strict ethical standards for submitted manuscripts in accordance with the guidelines of reputable international bodies. As a result, about a quarter of the submitted works have been rejected, the primary reason being the author trying to submit a previously published article. Sometimes authors believe that by making slight changes to the introduction, excluding a few people from the study, performing a new statistical analysis, and thus obtaining totally new results they will turn their old manuscript into a novel work. That is why we would like to talk about scientific integrity, honesty, plagiarism, and self-plagiarism in our special project “Author’s work”.
Richard FEYNMAN Cargo cult science
American physicist Richard P. Feynman, a Nobel laureate, was always very scrupulous about the quality of a research study. During his commencement address at the California Institute of Technology in 1974, he talked about scientific integrity and honesty and warned young researchers “not to fool” themselves. A must-read for anyone who believes he/she is a true scientist.
Ivan PAVLOV On the Russian mind
In 1918, Russian physiologist Ivan Pavlov, a Nobel laureate, delivered two lectures: on the mind in general and the Russian mind in particular; on those mind qualities that determine the success of a research work and on how these qualities are present in the Russian mind. Pavlov's thoughts are an effective vaccine against poor intellectual work.
