Exercise and physiological monitoring in isolated, confined and extreme environments and space analogues: A scoping review. [PDF]
Exp PhysiolAbstract This scoping review synthesized evidence on physical activity/exercise and physiological monitoring in isolated, confined and extreme (ICE) environments, with emphasis on Antarctic missions and space analogues. ICE exposures combine cold stress, confinement, disrupted light–dark cycles and psychosocial strain, which can challenge ...

Microgravity Effects on the Matrisome [PDF]
Cells, 2021 Gravity is fundamental factor determining all processes of development and vital activity on Earth. During evolution, a complex mechanism of response to gravity alterations was formed in multicellular organisms. It includes the “gravisensors” in extracellular and intracellular spaces.

Evaluation of Radiation Response in CoCrFeCuNi High-Entropy Alloys
Entropy, 2018 CoCrFeCuNi high-entropy alloys (HEAs) prepared by arc melting were irradiated with a 100 keV He+ ion beam. Volume swelling and hardening induced by irradiation were evaluated.

Microgravity crystallization of perdeuterated tryptophan synthase for neutron diffraction
, 2022 Biologically active vitamin B(6)-derivative pyridoxal 5′-phosphate (PLP) is an essential cofactor in amino acid metabolic pathways. PLP-dependent enzymes catalyze a multitude of chemical reactions but, how reaction diversity of PLP-dependent enzymes is ...
