Opis:
The structure and the dynamics of the argon thin film coating (15,4) and (12,12) carbon nanotubes have been studied in a series of molecular dynamic simulations. In the studied temperature regime, the argon atoms in the thin film were well localized. Structural changes and diffusion process inside the argon layers were not been observed. The influence of the chirality and the radius of the nanotube to the cluster properties is also reported.

Opis:
In this paper we apply the Asymmetric Detrended Fluctuation Analysis to the RR intervals time series. The mathematical background of the ADFA method is discussed in the context of heart rate variability and heart rate asymmetry. We calculate the α- and α+ ADFA scaling exponents for 100 RR intervals time series recorded in a group of healthy volunteers (20-40 years of age) with the use of the local ADFA. It is found that on average α+ < α-, and that locally α- dominates most of the time over α+ - both results are highly statistically significant.

Opis:
We investigate the variability of one of the most often used complexity measures in the analysis of the time series of RR intervals, i.e. Sample Entropy. The analysis is carried out for a dense matrix of possible r thresholds in 79 24h recordings, for segments consisting of 5000 consecutive beats, randomly selected from the whole recording. It is repeated for the same recordings in random order. This study is made possible by the novel NCM algorithm which is many orders of magnitude faster than the alternative approaches. We find that the bootstrapped standard errors for Sample entropy are large for RR intervals in physiological order compared to the standard errors for shuffled data which correspond to the maximum available entropy. This result indicates that Sample Entropy varies widely over the circadian period. This paper is purely methodological and no physiological interpretations are attempted.

Opis:
Multiple sclerosis is a chronic inflammatory disease which, due to the destruction of the fibres of the central nervous system in the process of demyelination, leads to numerous neurological symptoms and progressive disability. The disease is autoimmune, which means that myelin is destroyed by the patient’s own cells, caused by improper functionong and regulation of the immune system. Multiple sclerosis affects more and more people and is therefore a significant clinical problem which, to a large Entent, affects women, especially in childbearing age This presents a big challenge for carrying out pregnancy while continuing the therapy, ensuring the safety of the foetus and simultaneously achieving the best possible therapeutic effect. The decision whether the therapy should be continued or whether it should be eliminatedis usually made according to assessment of the possible gains and losse. Despite the lack of clear indications, there are many studies proving the relative safety of the use of individual but not all the drugs during pregnancy. Pregnancy, however, has a fairly good impact on the development of multiple sclerosis, and that safety considerations, especially those concerning the growing foetus, force a decision to change or completely suspend the therapy. In-depth research on the already available and emerging therapeutic pathways in multiple sclerosis bring hope for increasingly better results in the future in the treatment of pregnant patients with multiple sclerosis.
