Variants of two genes involved in the inflammatory system linked to cognitive decline after heart surgery

Duke University Medical Center researchers believe their findings could help physicians identify patients at risk of suffering mental decline after heart surgery and raises the possibility that these patients could be treated with drugs that are known to dampen the inflammatory response.

Biomarker discovery bodes well for better cancer diagnostics

While new findings from Ohio State University scientists suggest a genetic marker that could help distinguish between chronic pancreatitis and pancreatic cancer and gauge who will do well with cancer treatment, a pharmacologist at the Kimmel Cancer Center at Jefferson in Philadelphia sees the discovery as much more.

Unstable leukemia stem cells may predispose patients to drug resistance

The BCR-ABL gene in chronic myeloid leukemia stem cells has a tendency to quickly mutate, and this may help explain why patients are predisposed to resistance to drugs like imatinib that target that gene, according to a study in the May 2 Journal of the National Cancer Institute.

Green tea may help prevent bone destruction in arthritis

In rheumatoid arthritis, a person's own immune system attacks the joints by activating the synovial tissue that lines the body's movable joints, causing inflammation, swelling, pain and eventually erosion of the bone and cartilage and deformation of the joint.
