Chemo-radiation before prostate removal may prevent cancer recurrence

PORTLAND, Ore. — Researchers in the Oregon Health & Science University Knight Cancer Institute and the Portland Veterans Affairs Medical Center have found a combination of radiation therapy and chemotherapy given before prostate removal is safe and may have the potential to reduce cancer recurrence and improve patient survival.

Their findings were presented this week at the 51st annual meeting of the American Society of Therapeutic Radiology and Oncology in Chicago.

Report on US-China collaboration on carbon capture and sequestration

Lawrence Livermore National Laboratory's Julio Friedmann, in collaboration with the Center for American Progress, the Asia Society Center and with partner Monitor Group, today released the report, "A Roadmap for U.S.-China Collaboration on Carbon Capture and Sequestration."

Breeding better broccoli

CHARLESTON, SC—Carotenoids—fat-soluble plant compounds found in some vegetables—are essential to the human diet and reportedly offer important health benefits to consumers. Plant carotenoids are the most important source of vitamin A in the human diet; the carotenoids lutein and zeaxanthin, found in corn and leafy greens vegetable such as kale, broccoli, and spinach, are widely considered to be valuable antioxidants capable of protecting humans from chronic diseases including age-related macular degeneration, cancer, and cardiovascular disease.

New evidence supports 19th century idea on formation of oil and gas

Scientists in Washington, D.C. are reporting laboratory evidence supporting the possibility that some of Earth's oil and natural gas may have formed in a way much different than the traditional process described in science textbooks.

Tension on the grapevine

PROSSER, WA—Predictions of grape yields are extremely important to juice processors and wineries; timely and precise yield forecasts allow producers to plan for harvest and move the highly perishable grape crop from vine to processing efficiently. Until recently, wineries and grape juice processors have relied on expensive and labor-intensive hand-sampling methods to estimate yield in grape crops.

Toward home-brewed electricity with 'personalized solar energy'

New scientific discoveries are moving society toward the era of "personalized solar energy," in which the focus of electricity production shifts from huge central generating stations to individuals in their own homes and communities. That's the topic of a report by an international expert on solar energy scheduled for the November 2 issue of ACS' Inorganic Chemistry, a bi-weekly journal. It describes a long-awaited, inexpensive method for solar energy storage that could help power homes and plug-in cars in the future while helping keep the environment clean.

Powerful pumpkins, super squash

GAINESVILLE, FL—Carotenoids, the family of yellow to red pigments responsible for the striking orange hues of pumpkins and the familiar red color of vine-ripe tomatoes, play an important role in human health by acting as sources of provitamin A or as protective antioxidants. Pumpkins and squash, available in a wide range of white, yellow, and orange colors, are excellent sources of dietary carotenoids, particularly lutein, alpha-carotene, and beta-carotene.

Hybrid composite for root canal treatment

Unrelenting toothache means a visit to the dentist is inevitable, and if the tooth decay is really bad root canal treatment is often the only option. The dentist first removes the nerve completely and then closes the ensuing canal with a filler. This must be airtight to prevent bacteria from entering and causing renewed inflammation. On the other hand, the material must also be removable. If the natural crown is severely damaged, the dentist will anchor a root post in the previously filled canal using dental cement.

Great wines come from great soils

MADISON, WI, NOVEMBER 4, 2009 -- The world's greatest wines are the result of a threefold synergy among grape variety, human input, and something called the "terroir" -- a term often defined as the vineyard site, soil, and climate.

For African violets, 'hands off' means healthier

STILLWATER, OK—African violets have a mixed reputation. Their delicate, colorful flowers and furry, soft leaves make them a favorite among home gardeners and growers. But the striking plants are often regarded as temperamental: a precise recipe of light, moisture, warm temperatures, high humidity, and fertilizer is required to encourage african violets to grow and flower.

Pecan trees benefit from thinning technique

TIFTON, GA—Pecan trees, like many fruit trees, have a tendency to bear fruit in cycles, producing a large crop in one or two years, followed by one or two years with little or no crop. This cycle, called "alternate bearing", is the most profit-limiting biological problem facing pecan producers; the inconsistent production pattern creates supply and marketing challenges that can have severe negative effects on the pecan industry.

New theory on fairness in economics targets CEO pay

WEST LAFAYETTE, Ind. - Chief executives in 35 of the top Fortune 500 companies were overpaid by about 129 times their "ideal salaries" in 2008, according to a new type of theoretical analysis proposed by a Purdue University researcher to determine fair CEO compensation.

Weight training boosts breast cancer survivors' body image and intimate relationship satisfaction

In addition to building muscle, weightlifting is also a prescription for self-esteem among breast cancer survivors, according to new University of Pennsylvania School of Medicine research. Breast cancer survivors who lift weights regularly feel better about bodies and their appearance and are more satisfied with their intimate relationships compared with survivors who do not lift weights, according to a new study published in the journal Breast Cancer Research and Treatment.

Researcher says policymakers should do more to protect virtual privacy

The details of your personal life, such as grocery purchases and pizza topping preferences, are collected every day ― online and by club and discount cards from the gym, department store and supermarket. Though this data seems innocent enough, when it's put together it can tell a whole lot about your health, finances and behavior. That information, a Tel Aviv University researcher reminds us, could eventually be used against you.

New methods found useful for diagnosing myocarditis

ROCHESTER, Minn. -- Myocarditis is an important, and often unrecognized cause of dilated cardiomyopathy (DCM). Several new diagnostic methods, such as cardiac magnetic resonance imaging (MRI), are useful for diagnosing myocarditis, according to a study published in the November 2009 issue of Mayo Clinic Proceedings.

"The use of MRI is particularly significant in the diagnosis of patients with myocarditis because it is a standard, noninvasive method," says Leslie Cooper Jr., M.D., Mayo Clinic Division of Cardiovascular Diseases.
