    • X-ray crystallography at X-ray free-electron laser sources is a powerful method for studying macromolecules at biologically relevant temperatures. Moreover, when combined with complementary techniques like X-ray emission spectroscopy, both global structures and chemical properties of metalloenzymes can be obtained concurrently, providing insights into the interplay between the protein structure and dynamics and the chemistry at an active site. The implementation of such a multimodal approach can be compromised by conflicting requirements to optimize each individual method. In particular, the method used for sample delivery greatly affects the data quality. We present here a robust way of delivering controlled sample amounts on demand using acoustic droplet ejection coupled with a conveyor belt drive that is optimized for crystallography and spectroscopy measurements of photochemical and chemical reactions over a wide range of time scales. Studies with photosystem II, the phytochrome photoreceptor, and ribonucleotide reductase R2 illustrate the power and versatility of this method.

    • Objective: This study evaluated the ability of mental stress testing to discriminate between women with and without CHD, and among women with different disease manifestations, taking into account history of hypertension and beta -blocker use. Methods: Analyses were based on data from a community-based case-control study of women aged 65 years or younger. The study group consisted of 292 women who were hospitalized for an acute event of CHD, either AMI or unstable AP in Stockholm between 1991 and 1994. Controls were matched to cases by age and catchment area. Cardiovascular reactivity and emotional response to an anagram task solved under time pressure were measured 3 to 6 months after hospitalization. Results: Patients reacted with smaller increases in heart rate (4 bpm) than their controls (7 bpm). Results for the rate-pressure product were similar. Cardiovascular reactions did not distinguish patients with AP from those with AML History of hypertension (present in 50% of patients and 11% of controls) was related to enhanced diastolic blood pressure reactivity. Patients on beta -blockers (66%) had lower heart-rate levels throughout testing, but did not differ in their cardiovascular stress reactions when compared with the remaining participants. Conclusions: Women with heart disease have somewhat lower heart-rate responses to stress than healthy age-matched controls. History of hypertension is related to enhanced diastolic blood pressure reactivity to mental stress in both patients and controls.
