Mechanisms Of T Helper Cell Modulation In A Simulated Space Radiation Environment, Asma Rizvi
Mechanisms Of T Helper Cell Modulation In A Simulated Space Radiation Environment, Asma Rizvi
Loma Linda University Electronic Theses, Dissertations & Projects
Exposure to solar particle events (SPEs) poses the most serious threat to astronaut health. Due to this radiation environment, exploration of the solar system beyond Earth’s orbit entails many risks for the crew on these deep space missions. Depression or dysfunction of the immune system is a major concern due to its high radio-sensitivity; potential consequences include overwhelming infection, development of cancer, fibrosis, and poor wound healing. Astronauts are also exposed to low dose/low dose rate (LDR) radiation. A three month stay at the international space station exposes them to ~ 0.05 Gy of radiation.

Ms211: Letter From John Post To Armin & Karen, Armin Weinberg
Ms211: Letter From John Post To Armin & Karen, Armin Weinberg
Works on Radiation Effects: 1990-2020
This is a letter that accompanied a gift (tube with document inside that was printed by the original Gutenberg printing press) from John Post to Armin. John was a ret. Col. in medical logistics (at the US Dept of State) that helped distribute excess medical and hospital supplies to our AIHA partners in Kazakhstan, Azerbiajan and actually helped with shipment to Gaza as well. Since he lived in DC I invited him to a couple of the non-radiation related Intercultural Cancer Council Biennial Symposia that our Center at BCM coordinated. The page is now at the HRC for viewing.

Radiation-Induced Glutamate Transport Alterations In Neuron-Astrocyte Coupling, Martha Celia Sanchez

Exposure of the central nervous system (CNS) to ionizing radiation is known to result in behavioral, cognitive, and motor deficits - effects similar to those seen in many neurodegenerative disorders. Neurons and astrocytes, two principal cell types in the brain, coexist as an interdependent metabolic unit via the neurotransmitter glutamate. Disruption of this metabolic coupling would have widespread effects within the CNS, therefore it is hypothesized that ionizing radiation impairs glutamate transport and metabolism, and increases oxidative stress, ultimately impairing neuron-astrocyte coupling. We propose to investigate the mechanism and determine the impetus for radiation-induced neurotoxicity by measuring the temporal sequence …
