The influence of hypergravity (5, 8, 12 N.m2/kg2 for 15 min) on the activity of the antioxidant enzyme catalase and superoxide dismutase has been investigated in the blood, brain and liver tissues of rats in 15, 30, 60 min., and in 1, 3, 7 days after loading. It has been shown that peculiarities of the physiological response to the hypergravity of different intensity depend on the intensity of loading and functions of the tissues under investigation.

Hypergravity - an evolutionarily novel environment, enhances the resilience of wheat to simulated drought and salinity stress.

Article Synopsis
- Previous research shows that simulating hypergravity using centrifuges improves growth and root development in the wheat variety UAS 375, enhancing its ability to withstand stress.
- This study tested whether these root growth benefits could help wheat resist drought and salt stress across different wheat genotypes, finding that hypergravity exposure led to better seedling growth and increased resilience.
- Findings included changes in phytohormones and gene expression related to stress responses, indicating that hypergravity may boost stress resilience through genetic and hormonal modifications, consistent across various wheat types.
Wolffia globosa, a novel crop species for protein production in space agriculture.
Sci Rep
November 2024
Department of Agricultural Sciences, University of Naples Federico II, Portici, Italy.
Space agriculture, pivotal for sustainable extraterrestrial missions, requires plants that can adapt to altered gravitational conditions. This study delves into the adaptive responses to altered gravity of Wolffia globosa, an aquatic plant known for its rapid growth and high nutritional value. The research aimed to analyse the effect of simulated microgravity and hypergravity on relative growth rate (RGR), morphological characteristics, protein content, and the correlation between plant size and growth rate of Wolffia globosa.

Background: The exposure to artificial gravity (AG) through human centrifugation is the basis of the treatment called gravity therapy (GT), in which the mechanical stimulation over the vessel wall, induces the synthesis and release of prostacyclin. It has been used for more than four decades in Uruguay in the treatment of different vascular-based pathologies. In patients with systemic sclerosis (SSc) it has shown good benefits and excellent safety profile over the years.

Enzyme-induced carbonate precipitation (EICP) has been studied in the remediation of heavy metals in recent years. This study aims to investigate the impact of EICP with jack bean urease (JU) and sword bean urease (SU) on the Zn remediation. The results show that relatively high concentration of organic molecules in SU can protect urease from deactivation and absorb Zn.

Biomicrofluidics
September 2024
In recent years, the allure of space exploration and human spaceflight has surged, yet the effects of microgravity on the human body remain a significant concern. Immune and red blood cells rely on hematic or lymphatic streams as their primary means of transportation, posing notable challenges under microgravity conditions. This study sheds light on the intricate dynamics of cell behavior when suspended in bio-fluid under varying gravitational forces.
