Limitations in Predicting Radiation-Induced Pharmaceutical Instability during Long-Duration Spaceflight [PDF]

Nature Microgravity 5:15 (2019), 2019
As human spaceflight seeks to expand beyond low-Earth orbit, NASA and its international partners face numerous challenges related to ensuring the safety of their astronauts, including the need to provide a safe and effective pharmacy for long-duration spaceflight.

Medical Implications of Space Radiation Exposure Due to Low Altitude Polar Orbits [PDF]

Aerosp Med Hum Perform. 2018 Jan 1;89(1):3-8, 2017
Space radiation research has progressed rapidly in recent years, but there remain large uncertainties in predicting and extrapolating biological responses to humans. Exposure to cosmic radiation and Solar Particle Events may pose a critical health risk to future spaceflight crews and can have a serious impact to all biomedical aspects of space ...

Limitations in Predicting the Space Radiation Health Risk for Exploration Astronauts [PDF]

Nature Microgravity, Vol 4:8 (2018), 2017
Despite years of research, understanding of the space radiation environment and the risk it poses to long-duration astronauts remains limited. There is a disparity between research results and observed empirical effects seen in human astronaut crews, likely due to the numerous factors that limit terrestrial simulation of the complex space environment ...

A Comment on "The Far Future of Exoplanet Direct Characterization" - the Case for Interstellar Space Probes [PDF]

, 2010
Following on from ideas presented in a recent paper by Schneider et al. (2010) on "The Far Future of Exoplanet Direct Characterization", I argue that they have exaggerated the technical obstacles to performing such 'direct characterization' by means of fast (order 0.1c) interstellar space probes.

The Metabolic and Physiological Responses to Spaceflight of a Lipopeptide‐Producing Bacillus subtilis [PDF]

Microbial Biotechnology
Outer space is an extreme environment and the survival of many microorganisms after spaceflight is well established. However, adaptations of Bacillus subtilis to space stress, particularly metabolism, are largely unknown.

Effects of altered salt intake and diet on cytokines in humans: A 20‐week randomized cross‐over intervention study

European Journal of Immunology, Volume 53, Issue 1, January 2023., 2023
The effect of habitual Western diet and salt‐reduced diet on the levels of systemic blood cytokines was analyzed in a placebo‐controlled nutritional intervention study. The results showed that reduced salt intake did not alter the concentrations of any of the analyzed 34 cytokines in blood.

Automated Methods for Detecting and Quantitation of Enlarged Perivascular spaces on MRI

Journal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 11-24, January 2023., 2023
The brain's glymphatic system is a network of intracerebral vessels that function to remove “waste products” such as degraded proteins from the brain. It comprises of the vasculature, perivascular spaces (PVS), and astrocytes. Poor glymphatic function has been implicated in numerous diseases; however, its contribution is still unknown.

Fundamentals of Anesthesiology for Spaceflight [PDF]

Journal of Cardiothoracic and Vascular Anesthesia, 2016
SPACE EXPLORATION BEYOND low Earth orbit has been termed as “exploration class space missions.” Such future missions may involve extended flights to the Moon, asteroids, or Mars and will most likely engage not only governmental space agencies but also the private sector, in what some have termed “the new space race.” During those missions, the risk for

Preparation and properties of superhydrophobic epoxy composite coatings on magnesium alloys

Cailiao gongcheng, 2022
The traditional preparation process of superhydrophobic surfaces(SHS) is complicated and the mechanical stability of SHS is less than satisfactory in most cases, which seriously restricts the practical application. The "binder+nanoparticles" strategy was

Integrative transcriptomics and proteomics profiling of Arabidopsis thaliana elucidates novel mechanisms underlying spaceflight adaptation

Frontiers in Plant Science, 2023
Spaceflight presents a unique environment with complex stressors, including microgravity and radiation, that can influence plant physiology at molecular levels.
