Reactivation and shedding of cytomegalovirus in astronauts during spaceflight.
The reactivation of cytomegalovirus (CMV) in 71 astronauts was investigated, using polymerase chain reaction. A significantly greater (P<.0001) shedding frequency was found in urine samples from astronauts before spaceflight (10.6%) than in urine from the healthy control subject group (1.2%). Two of 4 astronauts studied during spaceflight shed CMV in urine. A significant increase (P<.0001) in C...
متن کاملDistance and Size Perception in Astronauts during Long-Duration Spaceflight
Exposure to microgravity during spaceflight is known to elicit orientation illusions, errors in sensory localization, postural imbalance, changes in vestibulo-spinal and vestibulo-ocular reflexes, and space motion sickness. The objective of this experiment was to investigate whether an alteration in cognitive visual-spatial processing, such as the perception of distance and size of objects, is ...
متن کاملEpstein-Barr virus shedding by astronauts during space flight.
Patterns of Epstein-Barr virus (EBV) reactivation in 32 astronauts and 18 healthy age-matched control subjects were characterized by quantifying EBV shedding. Saliva samples were collected from astronauts before, during, and after 10 space shuttle missions of 5-14 days duration. At one time point or another, EBV was detected in saliva from each of the astronauts. Of 1398 saliva specimens from 3...
متن کاملApplicability of the actigraphy for astronauts in spaceflight
Pandi-Perumal and Gonfalone presented perspective on sleep in space by overviewing the past medical reports [3]. The authors made special emphasis on “normal sleep” in space, where no gravity exists. According to their review, sleep in space was mainly monitored by subjective sleep diaries and actigraphy (wrist-worn accelerometer). As sleep cycle was developed in response to the 24 h rotation o...
متن کاملAdaptation of autonomic heart rate regulation in astronauts after spaceflight
BACKGROUND Spaceflight causes changes in the cardiovascular control system. The aim of this study was to evaluate postflight recovery of linear and nonlinear neural markers of heart rate modulation, with a special focus on day-night variations. MATERIAL/METHODS Twenty-four-hour Holter ECG recordings were obtained in 8 astronauts participating in space missions aboard the International Space S...
