Gene-metabolite networks associated with impediment of bone fracture repair in spaceflight
Computational and Structural Biotechnology Journal, 2021 Adverse effects of spaceflight on musculoskeletal health increase the risk of bone injury and impairment of fracture healing. Its yet elusive molecular comprehension warrants immediate attention, since space travel is becoming more frequent.

Neurosurgery and Manned Spaceflight [PDF]
Neurosurgery, 2018 ABSTRACT There has been a renewed interest in manned spaceflight due to endeavors by private and government agencies. Publicized goals include manned trips to or colonization of Mars. These missions will likely be of long duration, exceeding existing records for human exposure to extra-terrestrial conditions.

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

In situ synthesis of high dielectric constant GNPs/PBO nanocomposites with enhanced thermostability
IET Nanodielectrics, 2019 Graphite nanoparticles (GNPs) were introduced into poly(p-phenylene benzobisoxazole) (PBO) matrix to produce composites via in situ polymerisation. Films of various composites were fabricated through the solution casting method in methanesulfonic acid ...

Detections of Water Vapor Increase Over the North Polar Troughs on Mars as Observed by CRISM
Geophysical Research Letters, 2020 The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) onboard the Mars Reconnaissance Orbiter has been observing the north polar layered deposits (NPLD) of Mars. Polar wind circulations are instrumental in shaping the NPLD.

Root Skewing-Associated Genes Impact the Spaceflight Response of Arabidopsis thaliana
Frontiers in Plant Science, 2020 The observation that plant roots skew in microgravity recently refuted the long-held conviction that skewing was a gravity-dependent phenomenon. Further, spaceflight root skewing suggests that specific root morphologies and cell wall remodeling systems ...

Blood, 1982 A consistent deficit in the red cell mass has been observed during both the American and Soviet orbital space flights and is sometimes referred to as “astronaut anemia.” This may be associated with a reduction in plasma volume so that the hematocrit and the hemoglobin concentration remain unchanged.

An Observation‐Driven Approach to Improve Vegetation Phenology in a Global Land Surface Model
Journal of Advances in Modeling Earth Systems, 2020 An empirical model calibration approach is presented that aims to approximate missing biosphere processes in a global land surface model without the need for substantial model structural changes.
