Scientists put psoriasis drugs to the test

Clinical trials to test the effectiveness of two prescription drugs for the debilitating skin condition psoriasis have revealed significant differences that should help inform physicians treating patients with the condition.

Researchers at The University of Manchester compared the drugs etanercept and ustekinumab – relatively new biological therapies that have proved effective in the management of moderate to severe psoriasis.

Mapping and sequencing of soybean genome paves the way for improved soybean crops

Soybean, one of the most important global sources of protein and oil, is now the first major crop legume species with a published complete draft genome sequence. This sequence, which essentially provides a parts list of the soybean genome, will help scientists use the plant's genes to improve its characteristics. The soybean sequencing study appears as the cover story of the January 13 edition of Nature.

Migraine and depression may share genetic component

ST. PAUL, Minn. – New research shows that migraine and depression may share a strong genetic component. The research is published in the January 13, 2010, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Researchers tackle ductal carcinoma in situ and its many unanswered questions

An article and commentary published online January 13 in the Journal of the National Cancer Institute review available data on diagnosis and management of ductal carcinoma in situ (DCIS), and offer recommendations for the field. These include identification of better risk stratification methods, consideration of the elimination of the word "carcinoma" from the name, and further investigation into whether imaging technology and guidelines can be modified to focus on high-risk lesions.

New study raises the possibility that some antiviral drugs could make diseases worse

As the flu season continues in full-swing, most people can appreciate the need for drugs that stop viruses after they take hold in the body. Despite this serious need for new drugs, a team of researchers from the University of Texas at Austin raise serious concerns about an emerging strategy for stopping viral infections.

Dog genome researchers track paw prints of selective breeding

From the Dachshund's stubby legs to the Shar-Pei's wrinkly skin, breeding for certain characteristics has left its mark on the dog genome. Researchers have identified 155 regions on the canine genome that appear to have been influenced by selective breeding.

Unlocking the mystery of the duck-billed platypus' venom

Abandon any notion that the duck-billed platypus is a soft and cuddly creature -- maybe like Perry the Platypus in the Phineas and Ferb cartoon. This platypus, renowned as one of the few mammals that lay eggs, also is one of only a few venomous mammals. The males can deliver a mega-sting that causes immediate, excruciating pain, like hundreds of hornet stings, leaving victims incapacitated for weeks. Now scientists are reporting an advance toward deciphering the chemical composition of the venom, with the first identification of a dozen protein building blocks.

Toward a less expensive version of the anti-flu drug Tamiflu

Scientists have developed an alternative method for producing the active ingredient in Tamiflu®, the mainstay for fighting H1N1 and other forms of influenza. The new process could expand availability of the drug by reducing its cost, which now retails for as about $8 per dose. Their study is in ACS' Organic Letters, a bi-weekly journal.

New biomarkers for predicting the spread of colon cancer

Scientists in China are reporting discovery of two proteins present in the blood, of people with colon cancer that may serve as the potential biomarkers for accurately predicting whether the disease will spread. Their study is in ACS' Journal of Proteome Research, a monthly publication.

Investigators identify gene mutations in patients with Becker muscular dystrophy

Investigators in The Research Institute at Nationwide Children's Hospital have identified a link between specific modifications of the dystrophin gene and the age of cardiac disease onset in patients with Becker muscular dystrophy (BMD). This information could help clinicians provide early cardiac intervention for BMD patients based on genetic testing results performed on a blood sample. These findings are a result of analysis of the largest number of BMD patients to date and are published in the December issue of the journal Circulation: Cardiovascular Genetics.

National study finds table saw-related injuries have remained consistently high

Woodworking is a popular hobby, with table saws being owned and used by an estimated 6 million to 10 million people in the United States. Although table saws are associated with more injuries than any other woodworking tool, there have been no previously published national studies of table saw-related injuries.

Genome sequencing speeds ability to improve soybeans

WEST LAFAYETTE, Ind. - Purdue University scientists led an effort to sequence the soybean genome, giving researchers a better understanding of the plant's genes and how to use them to improve its characteristics.

Agronomy professor Scott Jackson said the U.S. departments of Energy and Agriculture study found that the soybean has about 46,000 genes, but many of those - 70 percent to 80 percent - are duplicates. This duplication may make it difficult to target the genes necessary to improve soybean characteristics such as seed size, oil content or yield.

From the ancient Amazonian Indians: A modern weapon against global warming

Scientists are reporting that "biochar" — a material that the Amazonian Indians used to enhance soil fertility centuries ago — has potential in the modern world to help slow global climate change. Mass production of biochar could capture and sock away carbon that otherwise would wind up in the atmosphere as carbon dioxide, the main greenhouse gas. Their report appears in ACS' Environmental Science & Technology, a bi-weekly journal.

Saving gorillas, elephants starts with understanding their human neighbors

WEST LAFAYETTE, Ind. - Understanding local human cultures is key to preserving gorillas, elephants and other wildlife in African parks and reserves, according to new research from Purdue University.

Genome sequencing shows past genetic events made soybeans rich in versatile gene families

Among the many plants that humans have found useful enough to domesticate, soybean (Glycine max) is a wonder. Like other legumes, it has the important ability to make some of its own essential nutrients by hosting nitrogen-fixing bacteria. Soybean is also a virtual chemical factory, so rich in proteins that it is a major source of protein for animal feed, and so rich in oils that it is used to produce much of the world's cooking oil; it is also a major source for biodiesel.
