The hemodynamic effects of acute and long-term administration of creatine phosphate were studied in 23 patients with heart failure (NYHA classes II and III) under stabilized treatment. Acute creatine phosphate (5 g i.v.) induced a significant increase of the ejection fraction (FE) and of other parameters of cardiac contractility. Once these improvements of cardiac contractility were obtained by acute treatment, further significant increases in cardiac function were observed if treatment was continued for six days, i.e. telesystolic diameter and volume, as well as parietal stress were significantly reduced, and ejection fraction and shortening fraction were significantly increased. Creatine phosphate treatment has a favourable influence on the hemodynamics of patients with an obvious contractility deficit and chronic ischemia of the myocardium.

Creatine (Cr) is recognized for its role in enhancing cognitive functions through the phosphocreatine (pCr)-creatine kinase system involved in brain energy homeostasis. It is reversibly converted into pCr by creatine kinase (CK). A brain-specific isoform of CK, known as CK-BB, is implicated in the brain's energy metabolism.

Foraminifera are ubiquitous marine protists that intracellularly accumulate phosphate, an important macronutrient in marine ecosystems and in fertilizer potentially leaked into the ocean. Intracellular phosphate concentrations can be 100-1,000 times higher than in the surrounding water. Here we show that phosphate storage in foraminifera is widespread, from tidal flats to the deep sea.

Creatine monohydrate supplementation is widely used by athletes in high-intensity, power-based sports due to its ability to enhance short-term performance by increasing intramuscular phosphocreatine (PCr) stores, which aid in ATP resynthesis during intense muscle contractions. However, emerging evidence suggests that creatine monohydrate offers benefits beyond athletic performance. This narrative review explores the literature supporting the advantages of creatine supplementation in women, vegans, and clinical populations.

Introduction: Ultra-high-field magnetic resonance (MR) systems (7 T and 9.4 T) offer the ability to probe human brain metabolism with enhanced precision. Here, we present the preliminary findings from 3D MR spectroscopic imaging (MRSI) of the human brain conducted with the world's first 10.

Background: Platinum-based chemotherapy provides curative treatment to more than 95% of patients with testicular germ cell tumor but it has negative cardiometabolic and neurological effects. Regular exercise can alleviate late chemotherapy-related toxicities. We examined the impact of a 6-month supervised aerobic-strength training on cognitive and cardiometabolic health and residual level of platinum in cancer survivors.
