Microgravity induced bone loss represents a critical health problem in astronauts, particularly occurred in weight-supporting skeleton, which leads to osteopenia and increase of fracture risk. Lack of suitable evaluation modality makes it d...
Insulin-like growth factor-1 receptor in mature osteoblasts is required for periosteal bone formation induced by reloading [0.03%]
胰岛素样生长因子1型受体对卸载后骨重建的膜质骨形成是必需的

Takuo Kubota et al.
Skeletal loading and unloading has a pronounced impact on bone remodeling, a process also regulated by insulin-like growth factor 1 (IGF-1) signaling. Skeletal unloading leads to resistance to the anabolic effect of IGF-1, while reloading a...
Cardiogenic mixing increases aerosol deposition in the human lung in the absence of gravity [0.03%]

Several laboratories have found large, highly reliable individual differences in the magnitude of cognitive performance, fatigue and sleepiness, and sleep homeostatic vulnerability to acute total sleep deprivation and to chronic sleep restr...
Validity and Sensitivity of a Brief Psychomotor Vigilance Test (PVT-B) to Total and Partial Sleep Deprivation [0.03%]
简明心理运动警觉性测验(PVT-B)用于总睡眠剥夺和部分睡眠剥夺的有效性和敏感度
Mathias Basner,Daniel Mollicone,David F Dinges
Mathias Basner
The Psychomotor Vigilance Test (PVT) objectively assesses fatigue-related changes in alertness associated with sleep loss, extended wakefulness, circadian misalignment, and time on task. The standard 10-min PVT is often considered impractic...
The dynamics of parabolic flight: flight characteristics and passenger percepts [0.03%]
高空抛物运动的特征及乘客的感觉反应机制研究

Flying a parabolic trajectory in an aircraft is one of the few ways to create freefall on Earth, which is important for astronaut training and scientific research. Here we review the physics underlying parabolic flight, explain the resultin...
Response Surface Mapping of Neurobehavioral Performance: Testing the Feasibility of Split Sleep Schedules for Space Operations [0.03%]
神经行为表现的响应面映射：测试太空任务中分段睡眠模式的可行性
Daniel J Mollicone,Hans P A Van Dongen,Naomi L Rogers et al.
Daniel J Mollicone et al.
The demands of sustaining high levels of neurobehavioral performance during space operations necessitate precise scheduling of sleep opportunities in order to best preserve optimal performance. We report here the results of the first split-...
Finger heat flux/temperature as an indicator of thermal imbalance with application for extravehicular activity [0.03%]
手指热流/温度作为热不平衡的指标在舱外活动中的应用研究
