A pilot study on the effects of olfactory stimulation with white musk aromatic oil on psychophysiological activity: a crossover study.
Sci Rep
January 2025
Department of Agro‑Environmental Sciences, Faculty of Agriculture, Kyushu University, 744 Motooka, Nishi‑ku, Fukuoka, 8190395, Japan.
Studies on the compounds of aromatic oils and their effects on psychophysiological changes in humans are often conducted separately. To obtain better validation, a suitable protocol is needed that can be extrapolated to large-scale olfactory stimulation experiments. Unfortunately, this type of study is still rarely performed.

Dissociative symptoms are a frequent complication in posttraumatic stress disorders affecting about a third of all PTSD patients. While theoretical models predict a physiological hypoarousal during posttraumatic dissociations, empirical evidence is lacking. We addressed this by studying spontaneously occurring dissociative symptoms and related heart rate changes in an ecological momentary assessment.

Department of Cardiology, The 904th Hospital of the PLA Joint Logistics Support Force, Wuxi, Jiangsu, 214044, People's Republic of China.
Objective: This study aims to develop a novel risk assessment tool for coronary artery disease (CAD) based on data of patients with chest pain in outpatient and emergency department, thereby facilitating the effective identification and management of high-risk patients.
Methods: A retrospective analysis was conducted on patients hospitalized for chest pain. Patients were divided into a control group and a CAD group based on angiographic results.
The effect of transcutaneous auricular vagus nerve stimulation on cardiovascular function in subarachnoid hemorrhage patients: A randomized trial.
Elife
January 2025
Department of Neurosurgery, Washington University School of Medicine, Springfield, United States.
Background: Subarachnoid hemorrhage (SAH) is characterized by intense central inflammation, leading to substantial post-hemorrhagic complications such as vasospasm and delayed cerebral ischemia. Given the anti-inflammatory effect of transcutaneous auricular vagus nerve stimulation (taVNS) and its ability to promote brain plasticity, taVNS has emerged as a promising therapeutic option for SAH patients. However, the effects of taVNS on cardiovascular dynamics in critically ill patients, like those with SAH, have not yet been investigated.

Faculty of Medicine, University of Oslo, Norway.
Intermittent negative pressure is an emerging treatment for lower limb vascular disease but the specific physiological effects, particularly upon large artery haemodynamics are unclear. This study examined the influence of intermittent negative pressure upon popliteal artery shear rate during both supine and sitting postures. Eleven healthy participants (5 female; age: 28.
