BACKGROUND Recent studies have shown the potential suitability of magnesium alloys as biodegradable implants. The aim of the present study was to compare the soft tissue biocompatibility of MgCa0.8 and commonly used surgical steel in vivo. METHODS A biodegradable magnesium calcium alloy (MgCa0.8) and surgical steel (S316L), as a control, were(More)
THE AIM OF THE STUDY Paper describes a study of language lateralization of patients with brain tumors, measured by preoperative functional magnetic resonance imaging (fMRI) and comparison results with tumor histology and profile of functional asymmetry. METHODS During the study 21 patient underwent fMRI scan. 15 patients had a tumor in the left and 6 in(More)
BACKGROUND Magnesium alloys as biodegradable implant materials received much interest in recent years. It is known that products of implant degradation can induce several types of immune response. Hence, the aim of this study was to examine the morphological changes of efferent lymph nodes after implantation of different resorbable magnesium alloys(More)
Study aim. To assess the efficacy of electrostimulation of the subthalamic nucleus (ES STN) in patients with Parkinson’s disease (PD) in comparison with drug treatment. Materials and methods. ES STN was performed in 22 patients (mean age 53.2 years, mean duration of illness 9.6 years). The control group consisted of 28 patients with PD who received drug(More)
Objective. To assess the clinical efficacy of deep brain stimulation (DBS STN) of the subthalamic nucleus in patients with Parkinson´s disease (PD) compared to pharmacological treatment. Material and methods. DBS STN was applied to 22 patients (mean age 53.2 years, mean disease duration 9,6 years). The control group included 28 patients (mean age 54.2(More)
