New Rochelle, NY, February 25, 2011—Hashimoto's thyroiditis (HT), an inflammatory disorder of the thyroid, is the most common cause of hypothyroidism, but a study has suggested that even when thyroid function is normal, HT may increase symptoms and decrease quality of life, as described in an article in Thyroid, a peer-reviewed journal published by Mary Ann Liebert, Inc. (www.liebertpub.com). Thyroid is the Official Journal of the American Thyroid Association (ATA).

The world watched in horror as Taliban fanatics ten years ago blew up the two gigantic Buddha statues that had since the 6th century looked out over the Bamiyan Valley in what is now Afghanistan. Located on the Silk Road, until the 10th century the 55 and 38 meter tall works of art formed the centerpiece of one of the world's largest Buddhist monastic complexes. Thousands of monks tended countless shrines in the niches and caves that pierced a kilometer-long cliff face.

Despite innumerable studies on lung cancer, many aspects of the disease have yet to be understood, including the role played by the retinoblastoma-related protein Rb2/p130 in the evolution of the disease.

Boston, MA – The World Bank and World Health Organization have voiced fears that policymakers will break their commitments to support desperately needed global health services in low- and middle-income countries because of the ongoing global economic downturn. Yet, according to a new study from the Harvard School of Public Health, there is surprisingly little historical evidence to justify reversing these commitments.

New research enhances the current knowledge of how human immunodeficiency virus type-1 (HIV-1), which causes AIDS, controls the cell cycle of cells that it infects. The new findings may shed light on how the virus reactivates after entering a dormant state, called latency.

"As we better understand the biological events that revive HIV from latency, we hope to devise ways to eventually intervene in this process with better treatments for people with HIV infection," said study leader Terri H. Finkel, M.D., Ph.D., chief of Rheumatology at The Children's Hospital of Philadelphia.

Heparin plays a key role in allergic and inflammatory reactions driven by mast cells, scientists from Karolinska Institutet in Sweden shows in an international collaboration involving colleagues from Germany and Switzerland. The study is published in the recent issue of Immunity, and sheds some new light on the biological function of heparin.

Whether doctors have knowledge of guidelines or not appears to be unsuitable as an indicator of how guidelines are being put into practice in the clinical routine.

Scientists at Trinity College Dublin have made an important discovery concerning how fledgling cancer cells self-destruct, which has the potential of impacting on future cancer therapies. The Trinity research group, led by Smurfit Professor of Medical Genetics, Professor Seamus Martin and funded by Science Foundation Ireland, has just published their findings in the internationally renowned journal, Molecular Cell.

COLUMBUS, Ohio – New research shows that a less-toxic combination of a targeted immune-based drug and a chemotherapy drug can produce long-term remissions in some chronic lymphocytic leukemia patients. And it does so without increasing the risk of later therapy-related myelodysplastic syndrome and acute myeloid leukemia, which can often occur with a three-drug combination used to treat these patients.

Spraying malaria-transmitting mosquitoes with a genetically modified fungus can kill the malaria parasite without harming the mosquito, potentially reducing malaria transmission to humans, according to a new study published in the journal Science. Funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, the study was led by Raymond J. St. Leger, Ph.D., of the University of Maryland, College Park.

MIAMI -- University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science faculty were part of an international scientific team to show that strong links between the corals reefs of the South China Sea, West Pacific and Coral Triangle hold the key to preserving fish and marine resources in the Asia-Pacific region.

An inexpensive and rapid testing method can effectively identify a sub-group of never-smoking lung cancer patients whose tumors express a molecule associated with increased risk of disease progression or recurrence, US researchers have found.

Dr Ping Yang from the Mayo Clinic, Rochester, USA, and colleagues, reported the findings at the European Multidisciplinary Conference in Thoracic Oncology (EMCTO), 24-26 February 2011, Lugano, Switzerland.

Spanish researchers have identified a gene whose expression level strongly predicts how well certain lung cancer patients will respond to treatment with the drug erlotinib.

Dr Rafael Rosell and colleagues reported their findings at the European Multidisciplinary Conference in Thoracic Oncology (EMCTO), 24-26 February 2011 in Lugano, Switzerland.

The researchers studied 55 patients with non-small cell lung cancer, whose tumors had mutations in the epidermal growth factor receptor (EGFR) gene. All were being treated with the drug erlotinib, which acts on the EGFR molecule.

A drug that is currently used to help treat bone metastases in patients with lung cancer could also be useful at an earlier stage of treatment, to prevent the cancer from spreading in the first place, Italian researchers have found.

Dr Michela Quirino and colleagues from the Catholic University of the Sacred Heart in Rome have reported important new evidence that zoledronic acid may be able to prevent lung cancer metastases from recruiting the new blood vessels they need to survive. This process of recruiting new blood vessels is called angiogenesis.

LONGYEARBYEN, NORWAY (25 February 2011)—The Svalbard Global Seed Vault (SGSV) celebrated its third anniversary today with the arrival of seeds for rare lima beans, blight-resistant cantaloupe, and progenitors of antioxidant-rich red tomatoes from Peru and the Galapagos Islands. The arrival of these collections, including many drought- and flood-resistant varieties, comes at a time when natural and man-made risks to agriculture have reinforced the critical need to secure all the world's food crop varieties.
