The effect of bed rest, unilateral limb immobilization and head‐down tilt on muscle protein synthesis: A systematic review and meta‐analysis

Experimental Physiology, EarlyView.
Abstract Muscle disuse leads to muscle atrophy and a decrease in muscle function that is primarily driven by reduced muscle protein synthesis (MPS). The aim of this systematic review and meta‐analysis was to examine the effect of different models of muscle disuse on rates of MPS.

Evaporation of Nanofluid Sessile Droplets Under Marangoni and Buoyancy Effects: Internal Convection and Instability

Nanomaterials
Previous research has studied the evolution of patterns during the evaporation of sessile droplets of pure liquid, although there is a lack of reports focusing on the transition of flow regimes and flow stability of nanofluids.

Temporary effects of random positioning on the function and plasticity of proliferating monocytes

Scientific Reports
The Random Positioning Machine (RPM) is used in the field of gravitational biology and space medicine. Rotational bioreactors such as the RPM create dynamic suspension cultures, providing shear stress, a crucial factor in circulatory homeostasis, but ...

Interferometry with Bose-Einstein Condensates in Microgravity

, 2013
Atom interferometers covering macroscopic domains of space-time are a spectacular manifestation of the wave nature of matter. Due to their unique coherence properties, Bose-Einstein condensates are ideal sources for an atom interferometer in extended ...

Non-Keplerian Charged Accretion Disk Orbiting a Black Hole Pulsar

Universe
Recent studies have focused on how spinning black holes (BHs) within a binary system containing a strongly magnetized neutron star, then immersed in external magnetic fields, can acquire charge through mechanisms like the Wald process and how this charge

NEX4EX – A novel exercise device enabling resistive, plyometric and sensorimotor training during deep‐space missions: A case report

Experimental Physiology, EarlyView.
Abstract During weightlessness, the human neuro–muscular–skeletal system undergoes maladaptation to the microgravity environment. The European Space Agency (ESA) project NEX4EX, ‘Novel Exercise Hardware for Exploration’, developed an advanced multipurpose exerciser offering resistive (RES), plyometric (PLYO) and sensorimotor (SENSO) exercises.

Spatial orientation under microgravity

Rinsho Shinkeigaku, 2012
On Earth, humans are constantly exposed to the gravity. During head and body tilts, the otolith organs sense changes in head orientation with respect to the gravitational vertical. These graviceptors also transduce transient linear acceleration generated by translational head motion and centripetal acceleration during rotation about a distant axis ...
