Stem cell research has been moving quickly. Swedish scientists , report in "Cell" that they had found brain stem cells. Their finding creates new hope for treating human diseases like Parkinson's and Alzheimer's, as well as for repairing injuries to the brain and spinal cord. Blood stem cells, which are found in bone marrow, are used to treat leukemia and other blood diseases. Stem cells from the umbilical cord also are used to treat blood disorders.
Researchers at University of Ulm Medical Center, Germany have reported that men with the highest levels of CRP had a more than twice the risk of having a heart attack or other heart disease-related problem compared to those men with low levels. CRP has been linked in past research to an increased risk of clogged. It is not clear what causes increased CRP levels, but the researchers speculate that it may be due to inflammation at the site of artery damage or to a low-grade infection elsewhere in the body.

Researchers at the Mayo Clinic in Rochester, Minnesota have reported that measurement of urinary telomerase appears to be a more sensitive and specific screening test for bladder cancer than other commonly used methods. Telomerase was compared to urine cytology, BTA stat, NMP22, fibrin/fibrinogen degradation products , telomerase, chemiluminescent hemoglobin and hemoglobin dipstick." They performed the tests using specimens from 57 patients with and 139 without bladder cancer. The sensitivity and specificity of the assay were 70% and 99%, respectively.
