The document discusses the results of a study on the effects of a new drug on memory and cognitive function in older adults. The double-blind study involved 100 participants aged 65-80 who were given either the drug or a placebo daily for 6 months. Researchers found that those who received the drug performed significantly better on memory and problem-solving tests at the end of the study compared to those who received the placebo.

This document is a bachelor thesis submitted by Luca Jan Schmidtke to the University of Heidelberg investigating the optimization of a 3D CEST sequence for imaging the human brain at 3 Tesla. The study optimized the flip angle and signal-to-noise ratio of the CEST sequence for signals mediated by exchange-relayed Nuclear Overhauser effects. The CEST pulse sequence was implemented with a saturation phase interleaved with a 3D fast gradient echo imaging sequence. Different segmentation schemes were investigated, and no significant difference was observed, though smaller numbers of saturation pulses are generally recommended.
