Admissibility of biochemical analyses results from sexual assault evidence in the United States courts.

Physiological stains in sexual assault cases have the potential to provide useful information. A comparison of genetic marker types in evidence semen stains and/or saliva stains to the corresponding genetic markers in the blood of a suspect may exclude the man as the perpetrator of the crime. If the genetic markers match, identification is inconclusive but may tend to support other circumstantial or eyewitness evidence of guilt.

Evaluation of a Reverse Gradient Garment for prevention of bed-rest deconditioning.

A Reverse Gradient Garment (RGG) was used to intermittently induce venous pooling in the extremities of a magnitude similar to that seen in going from a lying to standing position during the course of a 15-d period of horizontal bed rest. Venous pooling failed to improve bed-rest-induced losses in +2.5 Gz and +3.
