The Effects of Simulated Microgravity on Macrophage Phenotype [PDF]
Biomedicines, 2021 The effects of spaceflight, including prolonged exposure to microgravity, can have significant effects on the immune system and human health. Altered immune cell function can lead to adverse health events, though precisely how and to what extent a ...

Studies in microgravity, simulated microgravity and gravity do not support a gravitostat [PDF]
Journal of Endocrinology, 2020 The gravitostat is purported to function as a leptin-independent, osteocyte-dependent mechanism for regulation of energy balance. If correct, reduced activation of gravitostat signaling caused by prolonged sitting may contribute to obesity. The gravitostat concept is supported by reduced body mass in rodents following surgical implantation of weighted ...

Simulated microgravity in the ring-sheared drop [PDF]
npj Microgravity, 2020 AbstractThe ring-sheared drop is a module for the International Space Station to study sheared fluid interfaces and their influence on amyloid fibril formation. A 2.54-cm diameter drop is constrained by a stationary sharp-edged ring at some latitude and sheared by the rotation of another ring in the other hemisphere.

Responses of Haloarchaea to Simulated Microgravity [PDF]
Astrobiology, 2011 Various effects of microgravity on prokaryotes have been recognized in recent years, with the focus on studies of pathogenic bacteria. No archaea have been investigated yet with respect to their responses to microgravity. For exposure experiments on spacecrafts or on the International Space Station, halophilic archaea (haloarchaea)

Planarians Sense Simulated Microgravity and Hypergravity [PDF]
BioMed Research International, 2014 Planarians are flatworms, which belong to the phylumPlatyhelminthes.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.

Effects of Gravity, Microgravity or Microgravity Simulation on Early Mammalian Development [PDF]
Stem Cells and Development, 2018 Plant and animal life forms evolved mechanisms for sensing and responding to gravity on Earth where homeostatic needs require responses. The lack of gravity, such as in the International Space Station (ISS), causes acute, intra-generational changes in the quality of life.

Technology using simulated microgravity
Regenerative Therapy, 2023 The human body experiences constant stimulation from Earth's gravity, and the absence of gravity leads to various impacts at the cellular and tissue levels. Simulated microgravity (s-μg) has been employed on Earth to investigate these effects, circumventing the challenges of conducting experiments in space and providing an opportunity to understand the

Adaptation to simulated microgravity in Streptococcus mutans
npj Microgravity, 2022 AbstractLong-term space missions have shown an increased incidence of oral disease in astronauts’ and as a result, are one of the top conditions predicted to impact future missions. Here we set out to evaluate the adaptive response of Streptococcus mutans (etiological agent of dental caries) to simulated microgravity.

Expression pattern of neurotrophins and their receptors during neuronal differentiation of adipose-derived stem cells in simulated microgravity condition [PDF]
Iranian Journal of Basic Medical Sciences, 2017 Objective(s): Studies have confirmed that microgravity, as a mechanical factor, influences both differentiation and function of mesenchymal stem cells. Here we investigated the effects of simulated microgravity on neural differentiation of human adipose ...
