of a long surgery with significant blood loss. Infection can further reduce blood flow to the kidneys. Ironically, some antibiotics patients need for these infections also can harm the kidneys. Even the contrast medium needed to study kidney function...
Wisconsin scientists grow critical nerve cells
...the University of Wisconsin-Madison, are important because
they provide critical guideposts for scientists trying to repair damaged or diseased nervous systems. Motor neurons transmit messages from the brain and spinal cord, dictating almost every movement in the body from the wiggling of a toe to the roll...
Man and mouse share genome structures

different genes are on." Many scientists believe ...k these sites have important regulatory functions, because
the methylation patterns are similar in comparable portions of the mouse genome. Until now, they'd b...
Molecular biology fills gaps in knowledge of bat evolution
