Executive function in rats is impaired by low (20 cGy) doses of 1 GeV/u (56)Fe particles.

Exposure to galactic cosmic radiation is a potential health risk in long-term space travel and represents a significant risk to the central nervous system. The most harmful component of galactic cosmic radiation is the HZE [high mass, highly charged (Z), high energy] particles, e.g.

Low (20 cGy) doses of 1 GeV/u (56)Fe--particle radiation lead to a persistent reduction in the spatial learning ability of rats.

Exposure to galactic cosmic radiation (GCR) is considered to be a potential health risk in long-term space travel, and it represents a significant risk to the central nervous system (CNS). The most harmful component of GCR is the HZE [high-mass, highly charged (Z), high-energy] particles, e.g.

The identification of serum biomarkers of high-let radiation exposure and biological sequelae.

In the event of a nuclear detonation, thousands of people will be exposed to non-lethal radiation doses. There are multiple long-term health concerns for exposed individuals who receive non-lethal radiation exposures. Low doses of radiation, especially of high linear energy transfer (LET) radiation, can lead to the development of neurocognitive defects.

Comparison of the lateral tail vein and the retro-orbital venous sinus as routes of intravenous drug delivery in a transgenic mouse model.

In mice, intravenous injections are commonly administered in the lateral tail vein. This technique is sometimes difficult to carry out and may cause stress to mice. Though injection through the retro-orbital venous sinus can provide certain advantages over lateral tail vein injection, this method is poorly defined and infrequently used.

Lack of correlation of vaginal impedance measurements with hormone levels in the rat.

Hormone levels vary in female rats depending on estrous cycle stage. Vaginal cytology is a reliable method of staging female rats, but vaginal impedance offers an alternative depending on application. We sought to correlate vaginal impedance in cycling female rats with hormone levels.
