Stress can affect health. There is a growing need for the evaluation and application of professional stress management options, i.e, stress reduction. Mind/body medicine serves this goal, e.g, by integrating self-care techniques into medicine and health care. Tai Chi (TC) can be classified as such a mind/body technique, potentially reducing stress and affecting physical as well as mental health parameters, which, however, has to be examined further. ⋯ Subjective health increased, stress decreased (objectively and subjectively) during TC practice. Future studies should confirm this observation by rigorous methodology and by further combining physical and psychological measurements with basic research, thereby also gaining knowledge of autoregulation and molecular physiology that possibly underlies mind/body medicine.

Magnetic resonance coronary angiography (MRCA) is limited by a low signal-to-noise-ratio (SNR), low spatial resolution, and limited coverage of the coronary artery tree. These aspects might be significantly improved by intravascular contrast agents. The aim of the study was to evaluate the feasibility of whole-heart contrast-enhanced MRCA using the intravascular contrast agent gadofosveset, formerly known as MS-325. ⋯ Whole-heart coronary MRA with the intravascular contrast agent MS-325 enables significant improvement in CNR, blood-myocardial contrast, image quality, visible vessel length, and vessel sharpness over non-contrast MRCA.
