If the federal government implements a 2007 legal interpretation of the Endangered Species Act, the likely result will be a reduction in the number of species listed for protection, scientists say.

Researchers analyzed potential effects of a legal memorandum issued in March 2007 by the Department of the Interior, which, among other points, advised the U.S. Fish and Wildlife Service that only an endangered species' current range need factor into whether the species is listed for protection.

Trends among medical professionals have favored some treatments for younger men diagnosed with prostate cancer, but a new study by scientists at The Feinstein Institute for Medical Research and North Shore-LIJ Health System have found that age doesn't make a difference in the long-term therapeutic outcome.

Louis Potters, MD, chairman of radiation medicine at North Shore University Hospital and LIJ Medical Center, and his colleagues identified 2,119 consecutive prostate cancer patients treated between 1992 and 2005, and narrowed their selection to men under 60 years old.

Researchers at the University of Minnesota and National Institutes of Health have identified a new function for the protein missing in childhood muscular dystrophy.

Grand Rapids, Mich. (August 3, 2009) – A new diagnostic tool developed by Van Andel Research Institute (VARI) scientists has shown promising results when used with patients of pancreatic cancer, one of the deadliest forms of cancer due to the difficulty of diagnosing it in its early stages. The method, which studies carbohydrate structures in the bloodstream, could lead to the development of blood tests that can detect cancer more effectively.

SAN FRANCISCO, August 3, 2009 — The world’s top lung cancer specialists, medical professionals and researchers are convening this week in San Francisco, CA for the 13th World Conference on Lung Cancer (WCLC), organized by the International Association for the Study of Lung Cancer (IASLC). As non-small cell lung cancer (NSCLC) is one of the most common types of lung cancer affecting a heterogeneous population, researchers have focused on multi-modality treatment regimens to improve patient outcomes.

Brain scientists and cardiac surgeons at Johns Hopkins have evidence from 227 heart bypass surgery patients that long-term memory losses and cognitive problems they experience are due to the underlying coronary artery disease itself and not ill after-effects from having used a heart-lung machine.

Researchers say their latest findings explain study results presented last year, which showed that the heart-lung machines – used to pump blood and supply the body with oxygen while the heart is stopped during surgery – did not cause postoperative long-term brain deficits.

An international team of researchers has identified a new method for selectively killing metastatic melanoma cells. Melanoma is a cancer that is highly resistant to current treatment strategies.

Recent research has uncovered an unexpected vulnerability in deadly melanoma cells that, when exploited, can cause the cancer cells to turn against themselves. The study, published by Cell Press in the August issue of the journal Cancer Cell, identifies a new target for development of future therapeutics aimed at selectively eliminating this aggressive skin cancer which is characterized by a notoriously high rate of metastasis and treatment-resistance.

SAN DIEGO – (August 3, 2009) La Jolla Institute for Allergy & Immunology researchers studying an enzyme believed to play a role in allergy onset, instead have discovered its previously unknown role as a tumor suppressor that may be important in myeloproliferative diseases and some types of lymphoma and leukemia. Myeloproliferative diseases are a group of disorders characterized by an overproduction of blood cells by the bone marrow and include chronic myeloid leukemia. Lymphoma and leukemia are cancers of the blood.

Flasks, beakers and hot plates may soon be a thing of the past in chemistry labs. Instead of handling a few experiments on a bench top, scientists may simply pop a microchip into a computer and instantly run thousands of chemical reactions, with results — literally shrinking the lab down to the size of a thumbnail.

Rosemont, Ill. – Physicians should recommend low to moderate levels of exercise to their pregnant patients, even if they have not exercised prior to pregnancy, states a report published in the August 2009 issue of the Journal of the American Academy of Orthopaedic Surgeons (JAAOS). According to this review article, exercise can strengthen and improve overall musculoskeletal and physiologic health as well as pregnancy related symptoms. Exercise such as aerobics, impact and nonimpact activities, resistance training and swimming:

Heavy drinkers of beer and spirits face a much higher risk of developing cancer than the population at large, says a group of Montreal epidemiologists and cancer researchers. Their findings show that people in the highest consumption category increased their risk of developing oesophageal cancer sevenfold, colon cancer by 80% and even lung cancer by 50%.

Interventional radiology procedures are on the rise in developing countries and there is a significant need for optimization of these procedures to ensure patient safety. Many facilities in these countries lack the concept of patient dose estimation and dose management, putting patients at a higher risk of developing complications due to overexposure from radiation during interventional procedures, according to a study performed by the International Atomic Energy Agency in Vienna, Austria.

The use of digital mammography equipment alone is responsible for an increased number of breast cancers detected at a community-based mammography facility, according to a study performed at San Luis Diagnostic Center in San Luis Obispo, CA.

Children's after-school activities often consist of sedentary behavior such as watching television, but after-school programs that offer physical activity and healthy snacks could be the best place for children's health.

David Dzewaltowski, head of the department of kinesiology at Kansas State University, and other K-State researchers have found that quality after-school programs are an important contributor to children's physical activity.
