New Approach To Detect Early Progression Of Brain Tumors Identified (August 29, 2008) -- New research suggests a certain type of MRI scanning can detect when a patient is failing brain tumor treatment before symptoms appear. The results of the study pave the way for a proactive treatment approach. ... > full story
Doctors Performing Heart Surgery Face Risks To Eyes (August 29, 2008) -- Patients are not the only ones at risk during cardiac procedures. Doctors performing heart surgery also face health risks, namely to their eyes. The IAEA is helping to raise awareness of threats, through training in radiation protection related to medical uses of X-ray imaging systems. ... > full story
Atomic Bomb Effect Results In Adult-onset Thyroid Cancer Identified (August 29, 2008) -- Radiation from the atomic bomb blasts in Hiroshima and Nagasaki, Japan, in 1945, likely rearranged chromosomes in some survivors who later developed papillary thyroid cancer as adults, according to Japanese researchers. ... > full story
Americans Show Little Tolerance For Mental Illness Despite Growing Belief In Genetic Cause (August 29, 2008) -- While more Americans believe that mental illness has genetic causes, the nation is no more tolerant of the mentally ill than it was 10 years ago. ... > full story
Rapid Changes In Key Alzheimer's Protein Described In Humans (August 29, 2008) -- For the first time, researchers have described hour-by-hour changes in the amount of amyloid beta, a protein that is believed to play a key role in Alzheimer's disease, in the human brain. ... > full story
Growth Factor Predicts Poor Outcome In Breast Cancer (August 29, 2008) -- The response to insulin-like growth factor 1 (IGF-I) in breast cancer cells predicts an aggressive tumor that is less likely to respond to treatment, according to new research. The finding gives impetus to the movement to tailor cancer treatments to attributes of the various tumors. ... > full story
How Blood Vessel Cells Know To Form Tube-like Structures And Not Just Layers (August 29, 2008) -- How do blood vessel cells understand that they should organize themselves in tubes and not in layers? A special type of "instructor" molecule is needed, according to new research. This might be an important step towards using stem cells to build new organs. ... > full story
Physical And Sexual Abuse Linked To Asthma In Puerto Rican Kids (August 29, 2008) -- Children who are physically or sexually abused are more than twice as likely to have asthma as their peers, according to a recent study of urban children in Puerto Rico.

Black Raspberries Slow Cancer By Altering Hundreds Of Genes (August 29, 2008) -- New research strongly suggests that a mix of preventative agents, such as those found in concentrated black raspberries, may more effectively inhibit cancer development than single agents aimed at shutting down a particular gene. Researchers examined the effect of freeze-dried black raspberries on genes altered by a chemical carcinogen in an animal model of esophageal cancer. ... > full story
Variation Of Normal Protein Could Be Key To Resistance To Common Cancer Drug (August 29, 2008) -- Researchers have found evidence explaining why a common chemotherapy drug, cisplatin, may not always work for every cancer patient. They have shown that when a variant version of a key protein that normally causes cell death is active, patients may be resistant to the cancer-killing drug. ... > full story
Antidepressants In Suicide Prevention Reviewed (August 29, 2008) -- Scientists have presented the state of evidence concerning the relation of antidepressants and suicidal behavior and critically commented on the current discussion with regard to the role of antidepressive treatment in real-life clinical practice. ... > full story
