Note:From the abstract: "This review has three objectives: (1) to show the importance of studying vestibular precision, and specifically that studying accuracy without studying precision ignores fundamental aspects of the vestibular system; (2) to synthesize key hypotheses about precision in vestibular perception, the vestibulo-ocular reflex, posture, and neurons; and (3) to show that groups of studies that are thoughts to be distinct (e.g., perceptual thresholds, subjective visual vertical variability, neuronal variability) are actually 'two sides of the same coin' – because the methods used allow results to be related to the standard deviation of a Gaussian distribution describing the underlying neural noise."

Note:From the abstract: "A literature search was conducted using PubMed, Ovid and Scopus databases. 5541 studies were identified prior to the removal of duplicates and the application of the following inclusion criteria: (1) group means and standard deviations for pre- and post-spaceflight for measures of strength, muscle mass or bone density were reported (or provided by the corresponding author when requested via e-mail), (2) exercise-based countermeasures were included, (3) the population of the studies were human, (4) muscle function was assessed and (5) spaceflight rather than simulated spaceflight was used. The methodological quality of the included studies was evaluated using a modified Physiotherapy Evidence Database (PEDro) scale for quality, with publication bias assessed using a failsafe N (Rosenthal method), and consistency of studies analyzed using I2as a test of heterogeneity. Secondary analysis of studies included Hedges' g effect sizes, and between-study differences were estimated using a random-effects model." This article may be obtained online without charge.

[Effectiveness of the crew–mission control communication on the stages of adaptation to the conditions of long-term space mission.]
Note:ISS results. From the abstract: "The Content space experiment used content analysis to examine the features of the speech communication of Russian segment cosmonauts of the International Space Station with the mission control center (CMC)."
Note:Sirius 18/19 isolation and confinement analog mission results. From the abstract: "In the SIRIUS-18/19 project, psychological, neurohormonal and metabolic adaptation to 120-day isolation was studied with participation of 3 male and 3 female subjects between the ages of 28 to 44 years. Mood assessments and biochemical investigations attested to a moderate stress."

[State of the human innate immunity cell component during 120-day isolation in a pressurized module.]
Note:Sirius 18/19 isolation and confinement analog mission results. From the abstract: "Innate immunity was investigated in six 28 to 44 year old volunteers for a 120-day isolation in a controlled environment."
Note:From the abstract: "Analysis of realistic prototypes of a propulsive survival backpack (PSB) and current human-PSB models gave impetus to the development of original tools for designing the scenery and PSB application scenarios with consideration of the VR and 3D experiences in isolation studies and operators' training. Specifically, the authors created several VR/AR scenarios of emergency egress for participants in isolation studies."
