Patients who use medical marijuana for pain and other chronic symptoms can take an unwanted hit: Insurers don't cover the treatment, which costs as much as $1,000 a month. Once the drug of choice for hippies and rebellious teens, marijuana in recent years has gained more mainstream acceptance for its ability to boost appetite, dull pain and reduce seizures in everyone from epilepsy to cancer patients.

Soy sauce molecule may unlock drug therapy for HIV patients

May 6, 2014 7:49 am | News | Comments

For HIV patients being treated with anti-AIDS medications, resistance to drug therapy regimens is commonplace. Often, patients develop resistance to first-line drug therapies, such as Tenofovir, and are forced to adopt more potent medications. Virologists at the Univ. of Missouri now are testing the next generation of medications that stop HIV from spreading, and are using a molecule related to flavor enhancers found in soy sauce.

It won't be nearly as much fun as eating candy bars, but a big study is being launched to see if pills containing the nutrients in dark chocolate can help prevent heart attacks and strokes. The pills are so packed with nutrients that you'd have to eat a gazillion candy bars to get the amount being tested in this study, which will enroll 18,000 men and women nationwide.

Soy supplements with isoflavones “reprogram” breast cancer cells

February 25, 2014 8:05 am | by Sharita Forrest, News Editor, Univ. of Illinois, Urbana-Champaign | News | Comments

Women with estrogen-responsive breast cancer who consume soy protein supplements containing isoflavones to alleviate the side effects of menopause may be accelerating progression of their cancer, changing it from a treatable subtype to a more aggressive, less treatable form of the disease, new research suggests.

Better protein capture a boon for drug manufacturers

January 23, 2014 8:00 am | Videos | Comments

Rice Univ. scientists have created a way to fine tune a process critical to the pharmaceutical industry that could save a lot of time and money. A combination of the Rice technique that provides pinpoint locations for single proteins and a theory that describes those proteins’ interactions with other molecules could widen a bottleneck in the manufacture of drugs by making the process of isolating proteins five times more efficient.  

Can sunlight lower your blood pressure?

January 20, 2014 12:58 pm | News | Comments

Exposing skin to sunlight may help to reduce blood pressure and, thus, cut the risk of heart attack and stroke, a recently published study suggests. Research carried out at the Univs. of Southampton and Edinburgh shows that sunlight alters levels of the small messenger molecule, nitric oxide (NO) in the skin and blood, reducing blood pressure.

Study: Thinking positive helps migraine drug work

January 8, 2014 3:29 pm | by LAURAN NEERGAARD - AP Medical Writer - Associated Press | News | Comments

Talk about mind over matter: A quirky new study suggests patients' expectations can make a big difference in how they feel after treatment for a migraine. Boston researchers recruited 66 migraine patients in an attempt to quantify how much of their pain relief came from a medication and how much was due to what's called the placebo effect, the healing power of positive belief.

Study ties nuts to lower cancer, heart death risk

November 21, 2013 6:54 am | by MARILYNN MARCHIONE - AP Chief Medical Writer - Associated Press | News | Comments

Help yourself to some nuts this holiday season: Regular nut eaters were less likely to die of cancer or heart disease—in fact, were less likely to die of any cause—during a 30-year Harvard study. Nuts have long been called heart-healthy, and the study is the largest ever done on whether eating them affects mortality.

New way to target an old foe: malaria

July 18, 2013 3:57 pm | by Anne Trafton, MIT News Office | News | Comments

Although malaria has been eradicated in many countries, including the United States, it still infects more than 200 million people worldwide, killing nearly a million every year. In a major step toward reducing that number, a team led by MIT researchers has now developed a way to grow liver tissue that can support the liver stage of the life cycle of the two most common species of malaria.

Injectable “smart sponge” hold promise for controlled drug delivery

July 17, 2013 10:18 am | News | Comments

Researchers have developed a drug delivery technique for diabetes treatment in which a sponge-like material surrounds an insulin core. The sponge expands and contracts in response to blood sugar levels to release insulin as needed. The technique could also be used for targeted drug delivery to cancer cells.

Steering stem cells with magnets

July 16, 2013 2:43 pm | News | Comments

By feeding stem cells tiny particles made of magnetized iron oxide, scientists at Emory Univ. and Georgia Tech have used magnets to attract the cells to a particular location in the body after intravenous injection. The method could become a tool for directing stem cells’ healing powers to treat conditions such as heart disease or vascular disease.

Oregon scientists make embryos with 2 women, 1 man

October 26, 2012 9:26 am | by Malcolm Ritter, AP Science Writer | News | Comments

Scientists in Oregon have created embryos with genes from one man and two women, using a provocative technique that could someday be used to prevent babies from inheriting certain rare incurable diseases. The embryos are not being used to produce children, but it has already stirred a debate over its risks and ethics in Britain, where scientists did similar work a few years ago.

Complex logic circuits can be made from bacterial genes

October 12, 2012 5:07 pm | by Diana Lutz, Washington University in St. Louis, Tae Seok Moon, logic circuit, gene circuit | News | Comments

Logic circuits can be built from just about anything, including billiard balls, pipes of water, or animals in a maze. Tae Seok Moon, a professor at Washington University in St. Louis, intends to build logic gates out of genes, and has already built the largest such device yet reported. But the purpose of these circuits is not to crunch numbers.

Gene therapy boosts blood-clotting for hemophiliacs

December 12, 2011 5:22 am | by Mike Stobbe, AP Medical Writer | News | Comments

In what's being called a landmark study, researchers used gene therapy to successfully treat six patients with severe hemophilia, a blood-clotting disorder. The six men each received a single, 20-minute infusion of healthy genetic material delivered by a virus found in monkeys. Four of the patients were able to stop conventional blood-clotting treatments altogether.
