Effects of diamagnetic levitation on bacterial growth in liquid [PDF]

, 2010
Diamagnetic levitation is a technique that uses a strong, spatially-varying magnetic field to levitate diamagnetic materials, such as water and biological cells. This technique has the potential to simulate aspects of weightlessness, on the Earth.

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.

Crossover Scaling in Dendritic Evolution at Low Undercooling

, 1999
We examine scaling in two-dimensional simulations of dendritic growth at low undercooling, as well as in three-dimensional pivalic acid dendrites grown on NASA's USMP-4 Isothermal Dendritic Growth Experiment.

The effects of bed rest on cardiometabolic health: A systematic review and meta‐analysis

Experimental Physiology, EarlyView.
Abstract Horizontal bed rest (HBR) and head‐down tilt (HDT) are models of physical inactivity. In this systematic review and meta‐analysis, we aimed to quantify changes in cardiometabolic outcomes during HBR and HDT in healthy adults. Following the PRISMA guidelines, we searched PubMed, Scopus, Web of Science and Cochrane Library until 1 October 2025 ...

Establishing laboratory standards for biological flight experiments [PDF]

The general objective of this research was to assess the effects of exposure to simulated microgravity on ultrastructural aspects of the contractile system in chicken skeletal muscle cells. This general objective had two specific experimental components:

A study of murine bone marrow cells cultured in bioreactors which create an environment which simulated microgravity [PDF]

Previous research indicated that mouse bone marrow cells could be grown in conditions of simulated microgravity. This environment was created in rotating bioreactor vessels. On three attempts mouse cells were grown successfully in the vessels.

Transcapillary fluid shifts in head and neck tissues during and after simulated microgravity [PDF]

To understand the mechanism, magnitude, and time course of facial puffiness that occurs in microgravity, seven male subjects were tilted 6 degrees head down for 8 hr, and all four Starling transcapillary pressures were directly measured before, during ...
