Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

The role of orexin A in the pathogenesis of ischaemic stroke at high altitude

Experimental Physiology, EarlyView.
Schematic illustration of the experimental design. This study investigated the role of Orexin A in the pathogenesis of ischemic stroke at high altitude. Abstract Orexin offers protection against cerebral ischaemia–reperfusion injury, with high altitude playing a key role in modulating its expression.

Association between thyroid function and acute mountain sickness upon rapid ascent to 3650 m in euthyroid lowlanders in China

Experimental Physiology, EarlyView.
This study evaluated the association between baseline thyroid hormones levels, sensitivity index and the incidence of AMS in 70 healthy individuals traveling from Beijing (44 m above sea level) to Lhasa (3650 m above sea level). The dataset was divided into a training set (n = 56) and a validation set (n = 14) at an ratio of 8:2.

Combined effects of normobaric hypoxia and cold on respiratory system responses to high‐intensity exercise

Experimental Physiology, EarlyView.
Abstract Cold temperatures (<−15°C) increase exercise‐induced bronchoconstriction (EIB), while hypoxic‐induced hyperventilation exacerbates respiratory muscle fatigue for a given exercising task. This study aimed to determine the individual and combined effects of cold and normobaric hypoxia on the respiratory system responses to high‐intensity ...

Visual and vestibular reweighting after cyber‐ and space‐sickness

Experimental Physiology, EarlyView.
Abstract Sensory conflicts are widely recognized as the primary drivers of motion sickness (MS), though the underlying integrative processes remain poorly understood. This study investigated sensory reweighting following exposure to two different sensory conflict paradigms. Visual and vestibular reflexes were assessed before and after sensory conflict.
