The Impact of Microgravity and Hypergravity on Endothelial Cells

BioMed Research International, Volume 2015, Issue 1, 2015., 2015
The endothelial cells (ECs), which line the inner surface of vessels, play a fundamental role in maintaining vascular integrity and tissue homeostasis, since they regulate local blood flow and other physiological processes. ECs are highly sensitive to mechanical stress, including hypergravity and microgravity.

Rapid selection and proliferation of CD133+ cells from cancer cell lines: chemotherapeutic implications. [PDF]

PLoS ONE, 2010
Cancer stem cells (CSCs) are considered a subset of the bulk tumor responsible for initiating and maintaining the disease. Several surface cellular markers have been recently used to identify CSCs.

Stroboscopic Augmented Reality as an Approach to Mitigate Gravitational Transition Effects During Interplanetary Spaceflight

International Journal of Aviation, Aeronautics, and Aerospace, 2022
During interplanetary spaceflight, periods of extreme gravitational transitions will occur such as transitions between hypergravity, hypogravity, and microgravity.

Jumping on the moon as a potential exercise countermeasure

Experimental Physiology, EarlyView.
Abstract The Moon's gravitational field strength (17% Earth's gravity) may facilitate the use of bodyweight jumping as an exercise countermeasure against musculoskeletal and cardiovascular deconditioning in reduced gravity settings. The present study characterised the acute physiological and kinetic responses to bodyweight jumping in simulated Lunar ...

Swimming Activity Prevents the Unloading Induced Loss of Bone Mass, Architecture, and Strength in Rats

BioMed Research International, Volume 2015, Issue 1, 2015., 2015
We investigated whether swimming activity associated with a three‐week period of hypoactivity could prevent the deleterious effects of disuse on the tibias of tail‐suspended rats. Forty Wistar rats were divided into five groups: (HS) permanently hindlimb suspension rats; (HS + Swim) rats submitted to unloading interrupted by swimming exercise; (HS + WB)

Isoform‐Specific Na,K‐ATPase Alterations Precede Disuse‐Induced Atrophy of Rat Soleus Muscle

BioMed Research International, Volume 2015, Issue 1, 2015., 2015
This study examines the isoform‐specific effects of short‐term hindlimb suspension (HS) on the Na,K‐ATPase in rat soleus muscle. Rats were exposed to 24–72 h of HS and we analyzed the consequences on soleus muscle mass and contractile parameters; excitability and the resting membrane potential (RMP) of muscle fibers; the electrogenic activity, protein,

Effects of Static and Low‐Frequency Magnetic Fields on Gene Expression

Journal of Magnetic Resonance Imaging, Volume 62, Issue 2, Page 317-334, August 2025.
Substantial research over the past two decades has established that magnetic fields affect fundamental cellular processes, including gene expression. However, since biological cells and subcellular components exhibit diamagnetic behavior and are therefore subjected to very small magnetic forces that cannot directly compete with the viscoelastic and ...

Effects of 12‐Week Moderate‐Intensity Versus High‐Intensity Water‐Aerobic Training on Physical Fitness, Cardiovascular Health, and Well‐Being in Adults and Older Adults: A Pragmatic Randomized Controlled Trial

Health Science Reports, Volume 7, Issue 12, December 2024.
ABSTRACT Background and Aims The current study aimed to compare the effects of 12 weeks of moderate versus high‐intensity water aerobics on muscle strength, body composition, lipid profile, blood pressure, and quality of life in both adults and older adults. Methods Twenty‐one women (65.19 ± 9.37 years) were randomly allocated to moderate (MIG; n = 11)
