People with more years of education lose their memory faster than those with less education in the years prior to a diagnosis of dementia, according to a study published in the October 23, 2007, issue of Neurology®, the medical journal of the American Academy of Neurology.
On World Menopause Day, the International Menopause Society calls upon health authorities to re-evaluate the new age-related data on hormone therapy and review their recommendations accordingly, with an emphasis on women below 60, for whom the safety profile of HT is favorable and should not preclude women from using HT when appropriate.
The International HapMap Consortium today published analyses of its second-generation map of human genetic variation, which contains three times more markers than the initial version unveiled in 2005. In two papers in the journal Nature, the consortium describes how the higher resolution map offers greater power to detect genetic variants involved in common diseases, explore the structure of human genetic variation and learn how environmental factors, such as infectious agents, have shaped the human genome.
GlaxoSmithKline [NYSE: GSK] announced approval by the U.S. Food and Drug Administration (FDA) for oral Hycamtin ® (topotecan) capsules for the treatment of relapsed small cell lung cancer (SCLC).
Schizophrenia may occur, in part, because of a problem in an intermittent on/off switch for a gene involved in making a key chemical messenger in the brain, scientists have found in a study of human brain tissue. The researchers found that the gene is turned on at increasingly high rates during normal development of the prefrontal cortex, the part of the brain involved in higher functions like thinking and decision-making — but that this normal increase may not occur in people with schizophrenia.
A new report from the nation’s leading cancer organizations shows cancer death rates decreased on average 2.1 percent per year from 2002 through 2004, nearly twice the annual decrease of 1.1 percent per year from 1993 through 2002.
New data generated using mice by Charles Drake and colleagues at Johns Hopkins University School of Medicine, Baltimore, have identified a role for the protein LAG-3 in limiting the response of immune cells known as CD8+ T cells to both host and tumor proteins.
Eating garlic is one of the best ways to lower high blood pressure and protect yourself from cardiovascular disease. A new study from the University of Alabama at Birmingham (UAB) shows this protective effect is closely linked to how much hydrogen sulfide (H2S) is produced from garlic compounds interacting with red blood cells.
State-of-the-art detection and treatment have contributed to the ongoing decline in the cancer death rate in the United States. But most cancer patients do not receive care that addresses the psychological and social problems that frequently accompany cancer and its treatment.
Immune cells known as neutrophils produce reactive oxygen intermediates (ROIs) to combat infection with microbes that can cause diseases such as pneumonia. New insight into the molecular pathway regulating neutrophil production of ROIs in mice has been provided by Wojciech Swat and colleagues at Washington University School of Medicine, St. Louis.
