Licorice, the oldest Chinese traditional medicine, is widely used in the treatment of human diseases. Due to the deficiency of wild resource, selecting and breeding becomes a key issue to expanding the supply of licorice. Spaceflight technology will become a new method for medicinal plants. The aim of this study was to investigate the effect of spaceflight on the components and anti-inflamma...
During space flight, careful and complete physical measurements are made to characterize the radiation dose that is received by the astronauts. Biological changes are also evaluated in the astronauts to determine any biological changes induced by radiation during the space flight. Biological evaluations are done both before and after the space flight to ensure that the effects were induced by t...
A comprehensive analysis of both the molecular genetic and phenotypic responses of any organism to the space flight environment has never been accomplished because of significant technological and logistical hurdles. Moreover, the effects of space flight on microbial pathogenicity and associated infectious disease risks have not been studied. The bacterial pathogen Salmonella typhimurium was gr...

The space flight environment is known to induce bone loss and, subsequently, calcium loss. The longer the mission, generally the more bone and calcium are lost. This review provides a history of bone and calcium studies related to space flight and highlights issues related to calcium excretion that the space program must consider so that urine can be recycled. It also discusses a novel techniqu...
BACKGROUND Astronauts experience psychological and physical stresses that may result in reactivation of latent viruses during space-flight, potentially increasing the risk of disease among crewmembers. HYPOTHESIS The shedding of Epstein-Barr virus (EBV) in the saliva of astronauts will increase during spaceflight. METHODS A total of 534 saliva specimens were collected from 11 EBV-seropositi...
Flight Data Recorders (Black Boxes) generate data that is collected on an embedded memory device. A well-known difficulty with these devices is that the embedded memory device runs out of space. The worry of getting into this problematical situation compels the software of the flight data recorder to operate in a watchful mode it constantly makes efforts to minimize the use of memory space; oth...
