Although it is generally believed that the structure of venous thromboemboli is a homogeneous, their structure may be heterogeneous, with non-uniformly distributed platelet layers, known as the lines of Zahn. In the study we showed that venous thromboemboli ex vivo may contain platelet layers, i.e. the lines of Zahn. We explained their origin by numerical simulation, which showed that partial venous obstruction with stenosis or malfunctioning venous valves creates the conditions for eddy blood flow, which may explain the origin of heterogeneous structure of venous thromboemboli with twisted platelet layers.

In the study it was tested whether magnetic resonance electrical impedance tomography (MREIT) could enable efficient detection of areas with insufficient electric field coverage during electroporation based treatments. Sequences of high voltage pulses were applied to chicken liver tissue in order to expose it to electric field which was measured by means of MREIT. MREIT was also evaluated for its use in electroporation based treatments by calculating electric field distribution for two regions, the tumor and the tumor-liver region, in a numerical model based on data obtained from clinical study on electrochemotherapy treatment of deep-seated tumors. Electric field distribution inside tissue was successfully measured ex vivo using MREIT and significant changes of tissue electrical conductivity were observed in the region of the highest electric field.

In a series of studies we explore the TiO nanostructures as well as nanocrystals, grown from the scaffold and trace the generation of oxygen radicals via photoactivation. We correlate this with antimicrobial effect. We study also the effect of doping and stabilization on surfaces for antimicrobial protection of scaffolds, infrastructure and tool surfaces.

Astronomy and astrophysics are very popular with pupils, but the experimental work they can do tends to be rather limited. The search for life elsewhere in the Universe (ʼexobiologyʼ) has received an enormous boost since the detection of a rapidly increasing number of planets (ʼexoplanetsʼ) orbiting other stars in our galaxy. Recently (March 2012), a technique has been devised to determine if an exoplanet might be a suitable host for life. Despite the fact that exoplanets themselves cannot be resolved as separate objects, the technique exploits the polarization properties of the light they reflect from their parent star. This paper describes how this technique can be replicated easily on a model system in the school laboratory.
