Impact of a personalized intervention on preoperative anxiety and determination of the minimal clinically important difference in anxiety levels - a randomized clinical trial.

Background: Preoperative anxiety is common and most patients experiencing preoperative anxiety would welcome support to cope with their anxiety. Studies examining the effectiveness of information to reduce anxiety have been inconsistent. In addition, it is unclear whether results reported to be statistically significant are also clinically relevant.

The human RAD52 complex undergoes phase separation and facilitates bundling and end-to-end tethering of RAD51 presynaptic filaments.

Human RAD52 is a prime target for synthetical lethality approaches to treat cancers with deficiency in homologous recombination. Among multiple cellular roles of RAD52, its functions in homologous recombination repair and protection of stalled replication forks appear to substitute those of the tumor suppressor protein BRCA2. However, the mechanistic details of how RAD52 can substitute BRCA2 functions are only beginning to emerge.
