(2013-11-25)Microbial dysbiosis and toll-like receptor (TLR) signaling play a role in colonic injury and inflammation. Ulcerative colitis and radiation are known to alter microbiota, and diets containing polyphenols impact bacterial ...
-
(2018-11-09)Spaceflight poses a serious risk to human cardiovascular health in the form of microgravity-induced fluid shifts, exposure to ionizing space radiation, and unique environmental factors. The combinatorial effects of increased ...
-
(2012-07-16)NASA goals include long-term International Space Station (ISS) missions and the ambitious objective of eventually sending astronauts to Mars. Unfortunately, exposure to unloading due to microgravity during spaceflight has ...
-
(2018-06-08)Spaceflight exerts multiple environmental pressures upon astronauts causing both short and long-term physiological adaptations that may be debilitating and interfere with the ability for crewmembers to optimally function ...
-
(2017-05-08)Microgravity-related bone loss in astronauts is a well-known consequence of space travel. These losses are a result of the catabolic reaction of the skeleton to unloading. Anti-catabolics like bisphosphonates (BPs) have ...
-
(Texas A&M University, 2005-08-29)Knowledge of the two-phase flow state is fundamental for two-phase flow system design and operation. In traditional two-phase flow studies, the flow regime refers to the physical location of the gas and liquid in a conduit. ...
-
(2010-07-14)Flow regime transitions and the modeling thereof underlie the design of microgravity two-phase systems. Through the use of the zero-g laboratory, microgravity two-phase flows can be studied. Because microgravity two-phase ...

(2020-01-06)Osteoporosis-induced bone fractures affect approximately 2.6 million people in the United States, with over US$ 19 billion in related healthcare expenditures. Most of these patients live with this chronic condition, but ...
-
(2019-08-15)In recent years, NASA has reported that a significant number of astronauts are experiencing vision acuity loss after both short-term and long-term spaceflight missions. These visual impairments have been hypothesized to ...
