Genetic Mapping Triggers New Hope on Schizophrenia 

Scientists have linked more than 100 spots in our DNA to the risk of developing schizophrenia, casting light on the mystery of what makes the disease tick. Such work could eventually point to new treatments, although they are many years away. Already, the new results provide the first hard genetic evidence to bolster a theory connecting the immune system to the disease. Via AP.

CDC Director Warns of ‘Post Antibiotic Era’

The Centers for Disease Control and Prevention (CDC) warns that the government needs to take immediate action before we live in a world where life-saving antibiotics are no longer effective. “Every day we delay it becomes harder and more expensive to fix this problem,” said CDC Director Thomas Frieden Tuesday. Frieden says the healthcare system needs to improve how it detects patients with drug-resistant infections, controls the spread of such infections, prevents them from happening in the first place and incentivizes drugmakers to develop new antibiotics. Via The Hill.

A Sleep Apnea Test Without a Night in the Hospital

Sorry — must have nodded off for a decade. Ten years ago, I spent two nights in a sleep lab at SUNY Downstate Medical Center, taking the test for sleep apnea, and wrote about it for Science Times. Back then, “sleep technicians” wired me up like the Bride of Frankenstein: 15 sensors glued or clamped to my scalp, lip, eye sockets, jaw, index finger, chest and legs, two belts around my torso, and a “snore mike” on my neck.Via NY Times.

Functional Genomics Identifies Potential Therapeutic Targets for Clear Cell Renal Cell Carcinoma

Functional genomics has identified 31 potential therapeutic targets that contribute to clear cell renal cell carcinoma (ccRCC) proliferation, researchers report…Dr. John A. Copland from Mayo Clinic Comprehensive Cancer Center in Jacksonville, Florida and colleagues used a high-throughput gene microarray screen to identify genetic transcripts that are overexpressed at all stages of ccRCC (compared with matched normal kidney tissue). Via Medscape.

Why Mayo Clinic’s CEO Wants to Serve 200 Million Patients—and How He Plans to Do It

Question: I’ve read that before you joined the Mayo Clinic—and this was decades ago—one of your first encounters with the organization was when a physician was supposed to visit your hospital for a commemorative dinner…and he missed it. Can you talk a little bit about that? John Noseworthy: It was one of the two or three most pivotal moments in my life. You’re right, he missed his flight—and it was because he was with a patient. I was very young and I remember thinking, “who is this man who is so humble that he would put the needs of the patient ahead of his receiving  a distinguished recognition.” And then I wondered what organization could retain and keep a person like that. It was Mayo Clinic. Via Advisory Board.

Mayo Clinic Sees Bright Future for Personalized Medicine

Medical treatment will become more genetically specific to individuals as the 21st century progresses, the Mayo Clinic’s director of laboratory medicine told a congressional subcommittee Wednesday. Dr. Frank Cockerill said that Mayo, one of the world’s leaders in specialized diagnostics, develops 150 tests per year in an attempt to become more precise in treating patients. Via Star Tribune.

Medical research: Treat Ageing

Animals have evolved physiological redundancies, so manipulating a gene or signalling pathway does not necessarily change the function of an organ or organism. A drug that slows ageing should slow declines in several organ systems, but few laboratories can measure this in animals. One that does is the Healthspan Assessment Laboratory at the Mayo Clinic in Rochester, Minnesota. The lab quantifies muscle strength and cognitive impairment, and can measure body composition, metabolic rate, insulin sensitivity, motor coordination, bone density and exercise capacity. Via Nature.
