Opis:
In the present study, the effectiveness of a mixture of silver nanoparticles with polyhydric alcohols (glycerol, erythritol, mannitol and xylitol) against six species of healthpromoting bacteria have been examined. Synthesis of silver nanoparticles was carried out using trisodium citrate as the reducing and stabilizing agent. The nanoparticles were characterized by electronic absorption, scanning electron microscopy and powder X-ray diffraction measurements. Electronic absorption spectrum revealed high uniform of synthesized nanoparticles. Practically no aggregation was observed when nanoparticles were mixed with polyhydric alcohols, suggesting weak interaction between ingredients of the mixture. Spherical silver nanoparticles, as depicted by scanning electron microscopy, were found to have diameters in the range of 10 to 30 nm; mean diameter was 18 ± 4 nm. The X-ray diffraction pattern of the prepared samples indicated the face-centred cubic crystalline structure of the metallic silver nanoparticles. In biological study, quite interesting protective effect of polyalcohols on the growth inhibition of health-promoting bacteria by silver nanoparticles was observed. The most substantial protective effect of the tested silver nanoparticles-polyalcohol mixtures was estimated for B. bifidum, L. paraplantarum, and L. phamnosus species.

Opis:
Chromatoelectrophoresis is a laboratory technique which depicts changes in multiple protein fractions inclusively. The combined, simultaneous analysis based on two key protein features (charge and molecular weight) offers a unique opportunity for better understanding of serum protein composition as well as it indicates the fraction which needs more thorough investigation. Because of those promising features, the chromatoelectrophoresis with automated analysis is expected to be a valuable laboratory test, aiding the process of medical diagnosis. However, without information technology support, analyzing the results of chromatoelectrophoresis would be tedious and time-consuming. For better optimization, both an algorithm for output image analysis and application with user-friendly interface were developed. Planning, development and testing were conducted at AGH University of Science and Technology and Jagiellonian University, Medical College in Cracow, Poland. With this article, we present the results of the first year of cooperation, code-named ChromSee.org project. The algorithm for distinguishing, naming and analyzing the content of fractions, the application and their utility in real-life settings are described, as well as potential future developments.

Opis:
Gastrooesophageal reflux disease is the regurgitation of stomach contents into the esophagus, which causes troublesome symptoms or complications for the patient. Before starting the treatment, it is always necessary to objectively confirm gastroesophageal reflux disease, especially in correlation with ENT symptoms, as extra esophageal complications. In diagnostics, the "gold standard" is a 24-hour impedance-pH supplemented with endoscopy. Treatment without objective confirmation of the disease is not recommended, the more so that non-acid gas proximal reflux, detectable only in the MIIpH test, causes the greatest number of laryngological complications. It is important to confirm the coexistence of clinical symptoms of GERD with ESS. Considering the time of treating the disease and its consequences, it is worthwhile to be cautious and careful with the diagnosis of the disease, and the treatment should be carried out for a long time in relation to the recommendation, preferably in cooperation with an ENT specialist and gastroenterologist. The greatest therapeutic effectiveness is achieved by combining PPI with itopride while maintaining the appropriate doses of drugs and observing a sufficiently long duration of treatment, while maintaining the correct dose reduction and drug discontinuation regimen. In case of failure of pharmacological treatment, antireflux surgery should be take into consideration.
