Planarians Sense Simulated Microgravity and Hypergravity
Planarians are flatworms, which belong to the phylum Platyhelminthes. They have been a classical subject of study due to their amazing regenerative ability, which relies on the existence of adult totipotent stem cells. Nowadays they are an emerging model system in the field of developmental, regenerative, and stem cell biology. In this study we analyze the effect of a simulated microgravity and...
متن کاملHypergravity and microgravity influence haemostasis.
Thromb Haemost 2009; 101: 799 Cosmonauts flying to the International Space Station with the Sojuz rocket or taikonauts in their space capsule have to sit in their chair inside the narrow space capsule for up to two days. Thus, they seem to be susceptible to the risk of venous thrombosis and thromboembolism like anybody sitting with knees bent for an extended period of time, e.g. during air trav...
متن کاملThe Impact of Microgravity and Hypergravity on Endothelial Cells
The endothelial cells (ECs), which line the inner surface of vessels, play a fundamental role in maintaining vascular integrity and tissue homeostasis, since they regulate local blood flow and other physiological processes. ECs are highly sensitive to mechanical stress, including hypergravity and microgravity. Indeed, they undergo morphological and functional changes in response to alterations ...
متن کاملEffects of microgravity and hypergravity on platelet functions.
Many serious thrombotic and haemorrhagic diseases or fatalities have been documented in human being exposed to microgravity or hypergravity environments, such as crewmen in space, roller coaster riders, and aircrew subjected to high-G training. Some possible related organs have been examined to explore the mechanisms underlying these gravity change-related diseases. However, the role of platele...
متن کاملMicrogravity decreases and hypergravity increases exhaled nitric oxide.
Inhalation of toxic dust during planetary space missions may cause airway inflammation, which can be monitored with exhaled nitric oxide (NO). Gravity will differ from earth, and we hypothesized that gravity changes would influence exhaled NO by altering lung diffusing capacity and alveolar uptake of NO. Five subjects were studied during microgravity aboard the International Space Station, and ...
