Tumor necrosis factor can suppress inflammation, treat rheumatoid arthritis

A new study by rheumatologists at Hospital for Special Surgery in New York has shown that a powerful pro-inflammatory protein, tumor necrosis factor, can also suppress aspects of inflammation.

Scientists invent Monolayer Stress Microscopy to measure physical forces during collective cellular migration

The physical forces that guide how cells migrate-how they manage to get from place to place in a coordinated fashion inside the living body- are poorly understood. Scientists at the Harvard School of Public Health and the Institute for Bioengineering of Catalonia have, for the first time, devised a way to measure these forces during collective cellular migration.

Researchers identify new drug resistant protein in breast cancer

Researchers have identified a new protein involved in the development of drug resistance in breast cancer which could be a target for new treatments, they report today in the journal Nature Medicine.

Salk researchers successfully edit diseased gene in patient-specific induced pluripotent stem cells

In principle, genetic engineering is simple, but in practice, replacing a faulty gene with a healthy copy is anything but. Using mutated versions of the lamin A gene as an example to demonstrate the versatility of their virus-based approach, researchers at the Salk Institute for Biological Studies successfully edited a diseased gene in patient-specific induced pluripotent stem cells as well as adult stem cells.

Modified cells protect marrow and blood cells from harmful chemotherapy effects in brain tumor patients

Although chemotherapy is used to kill cancer cells, it can also have a strong toxic effect on normal cells such as bone marrow and blood cells, often limiting the ability to use and manage the chemotherapy treatment.

Golden Helix integrates CMC and KBAC methods of analyzing rare DNA sequence variants in SVS product

Though two of the best-known methods for analyzing rare variants in sequencing data were published in 2008 and 2010, they have never been available to the public as a supported package.

Antibodies produced in space less effective than those produced on terra firma

The trip to Mars just got a little more difficult now that French researchers have discovered that antibodies used to fight off disease might become seriously compromised during long-term space flight. In a new report published online in the FASEB Journal, the scientists show that antibodies produced in space are less effective than those produced on terra firma.

Syngenta plans new $71 million state-of-the-art biotechnology research facility in North Carolina

Syngenta announced today that it plans to construct a new state-of-the-art biotechnology research facility adjacent to its existing research campus in Research Triangle Park, North Carolina. The $71 million investment, which is scheduled to begin in June 2011, will focus on discovering and developing new agronomic traits to bring innovative solutions to growers across the world.

Researchers uncover new details of unusual biological mechanism in brains of diverse species

Researchers at the University of California, San Diego School of Medicine have uncovered new details of an unusual biological mechanism in the brains of diverse species that not only helps regulate how their brains develop, but also how they function later in life. The discovery could lead to new biomarkers for specific neurological diseases in humans and, possibly, the development of drugs to cure them.

Patch angioplasty improves post-exercise ABI's and reduces reoperation rates in competitive cyclists

Results from a midterm study of highly competitive cyclists who underwent external iliac artery reconstruction (AR) and inguinal ligament release (LR) were reported today at the 65th Vascular Annual Meeting® presented by the Society for Vascular Surgery (SVS).

Multiple toxic mechanisms link elevated iron, copper levels in the brain and extensive DNA damage

No one knows the cause of most cases of Alzheimer's, Parkinson's and other neurodegenerative disorders. But researchers have found that certain factors are consistently associated with these debilitating conditions.

Stopping prostate cancer cells from 'bulking up' with nutrients blocks spread of disease

Cancer Research UK scientists have discovered that stopping prostate cancer cells from 'bulking up' with nutrients reduces the spread of the disease and tumour size, according to research published today in EMBO Journal.

Healthy breakfast containing protein-rich foods can help people stay satisfied longer

A University of Missouri researcher has found that eating a healthy breakfast, especially one high in protein, increases satiety and reduces hunger throughout the day. In addition, using functional magnetic resonance imaging (fMRI) the researchers found that eating a protein-rich breakfast reduces the brain signals controlling food motivation and reward-driven eating behavior.

Inorganic nitrate reduces rate of heart dysfunction caused by doxorubicin

Virginia Commonwealth University researchers have found that nutrient supplementation, like the kind that is found in leafy greens, spinach and lettuce, may reduce the damage to the heart caused by a powerful anti-cancer drug.

Bitter cumin contains high levels of antioxidants and protects against DNA damage

Bitter cumin is used extensively in traditional medicine to treat a range of diseases from vitiligo to hyperglycemia. It is considered to be antiparasitic and antimicrobial and science has backed up claims of its use to reduce fever or as a painkiller. New research published in BioMedCentral's open access journal BMC Complementary and Alternative Medicine shows that this humble spice also contains high levels of antioxidants.
