Experimental Physiology, Volume 111, Issue 9, Page 4115-4125, 1 September 2026.Abstract Astronauts experience combined exposure to a cephalad fluid shift and mild hypercapnia during space missions, potentially contributing to health problems. Such combined exposure may weaken dynamic cerebral autoregulation. The magnitude of cephalad fluid shift varies between individuals, and dynamic cerebral autoregulation may be affected more ...

Experimental Physiology, Volume 111, Issue 9, Page 4223-4234, 1 September 2026.Abstract A reduction in cerebral blood flow (CBF) has been observed during spaceflight and bed rest. We aimed to examine the magnitude and regional heterogeneity of the decrease in CBF during bed rest compared to posture changes on Earth. Seventeen participants (age, 29 ± 9 years, 7 females) were studied in the upright and supine posture and over 3 ...

Experimental Physiology, Volume 111, Issue 9, Page 4235-4247, 1 September 2026.Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.

Unusual Evidence of Fat Embolism in the Subclavian Vein Detected by High-Intensity Transient Signals
Methodist DeBakey Cardiovascular JournalFat emboli may occur in patients after traumatic fractures or orthopedic procedures; however, their clinical detection is a very rare finding. Here, we describe a 77-year-old female who was admitted to the emergency department with a fracture of the ...

Experimental Physiology, Volume 111, Issue 9, Page 4054-4063, 1 September 2026.Abstract Maintaining corticospinal tract function is crucial for voluntary movement. Exercise using high external loads/intensities is a promising intervention to promote adaptations to the corticospinal tract and improve physical function; however, such loads/intensities may not be tolerable or safe in populations with neurological disorders, motor ...

Transcranial Doppler ultrasound in neurovascular diseases: diagnostic and therapeutic aspects
, 2012 Albeit no direct anatomical information can be obtained, neurosonological methods provide real-time determination of velocity, and spectral waveform of blood flow in basal intracranial arteries adds significant benefit to the care of the patients with ...
