Cyclodextrin Polymers: Recent Applications

Abstract: In this article, the applications of CD polymers are presented. The text consists of two parts. In the first one, the applications of CD polymers in environmental protection, especially detoxification from heavy metals and organic contaminants, are described. The second part concerns application of CD polymers in pharmaceutics and cosmetics. Keywords: cyclodextrin polymers; adsorption; drug; environment; wastewater

The Use of Virtual Therapy in Cardiac Rehabilitation of Female Patients with Heart Disease

Abstract: Background and Objectives: Cardiovascular disease (CVD) has become increasingly prevalent in women, and it is also in this group that the risk of developing depression is the highest. The most commonly applied therapeutic intervention in cardiac rehabilitation is Schultz’s autogenic training, which has proven to be of little efficacy in reducing depression and anxiety disorders. At the same time, a growing number of scientific reports have been looking at the use of virtual reality (VR) to treat mental health problems. This study aimed at assessing the efficacy of virtual therapy in reducing levels of depression, anxiety, and stress in female CVD patients. Materials and Methods: The study included 43 women who were randomly divided into two groups: experimental group (N = 17), where eight-week cardiac rehabilitation was enhanced with VR-based therapeutic sessions, and control group (N = 26), where the VR therapy was replaced with Schultz’s autogenic training. Mental state parameters were measured using the Perception of Stress Questionnaire and Hospital Anxiety and Depression Scale (HADS). Results: In the experimental group, the sole parameter which failed to improve was HADS-Anxiety, which remained at the baseline level. In the control group, there was a deterioration in nearly all tested parameters except for HADS-Depression. Statistically significant differences in the efficacy of rehabilitation were recorded in relation to the level of stress in the sub-scales: emotional tension (p = 0.005), external stress (p = 0.012), intrapsychic stress (p = 0.023) and the generalized stress scale (p = 0.004). Conclusions: VR therapy is an efficient and interesting complement to cardiac rehabilitation, with proven efficacy in reducing stress levels.

Redetermination of 9,10‐dimethylanthracene

Abstract: The crystal structure of the title compound, C16H14, was refined by Iball & Low [Acta Cryst. (1974). B30, 2203–2205] to an R value of 0.080. The present redetermination confirms the previous study but with improved precision and with all H atoms located and refined. The atoms of the methyl group are disordered over two sites with occupancies 0.55 (3) and 0.45 (3). The mol­ecular symmetry is Ci. The crystal structure is stabilized by van der Waals inter­actions.
