Earlier Detection Of Diseases Likely With New Super-Sensitive Tests
5/29/2012
Scientists have developed an ultra-sensitive test that should enable them to detect signs of a disease in its earliest stages, in research published in the journal Nature Materials. The scientists, from Imperial College London and the University of Vigo, have created a test to detect particular molecules that indicate the presence of disease, even when these are in very low concentrations...
Physicians Have Trouble Stopping PSA Tests, Despite Questionable Benefits
5/29/2012
Recent recommendations from the U.S. Preventive Services Task Force (USPSTF) advising elimination of routine prostate-specific antigen (PSA) screening for prostate cancer in healthy men are likely to encounter serious pushback from primary care physicians, according to results of a survey by Johns Hopkins investigators...
Overactive Leukemia Gene May Be Explained By Inherited DNA Change
5/29/2012
A small inherited change in DNA is largely responsible for overactivating a gene linked to poor treatment response in people with acute leukemia. The study by researchers at the Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James) focused on a gene called BAALC...
Does A Safe Suntan Exist? Apparently Not
5/29/2012
Dermatologists from Penn State University say that a safe tan does not exist. The incidence of melanoma, a fatal form of skin cancer, was eight times higher among women and four times higher among men in 2009 compared to 1970. Sixty thousand people are diagnosed with melanoma each year in the USA - one American dies every hour from the disease...
Scars, Disfigurement And Hair Loss From Childhood Cancer Can Affect Adult Quality Of Life

Scars left behind by childhood cancer treatments are more than skin-deep...
Findings Suggest Cancer Cells May Grow More Easily Than Researchers And Clinicians Had Hoped
5/29/2012
Chromosomal deletions in DNA often involve just one of two gene copies inherited from either parent. But scientists haven't known how a deletion in one gene from one parent, called a "hemizygous" deletion, can contribute to cancer...
Cancer-Promoting, Glucose-Processing Akt Activated By Skp2
5/29/2012
HER2 and its epidermal growth factor receptor cousins mobilize a specialized protein to activate a major player in cancer development and sugar metabolism, scientists report in Cell. This chain of events, the scientists found, promotes Herceptin resistance in breast cancer and activation of glucose metabolism (glycolysis), which cancer cells primarily rely on to fuel their growth and survive...
Size Of Clot-Forming Cells Predicted By Mathematical Model
5/29/2012
UC Davis mathematicians have helped biologists figure out why platelets, the cells that form blood clots, are the size and shape that they are. Because platelets are important both for healing wounds and in strokes and other conditions, a better understanding of how they form and behave could have wide implications...
Proteomic Analysis Of Immunocamouflaged Surfaces
5/29/2012
The transfusion of red blood cells (RBC) is a critical component in the treatment of a number of acute and chronic medical problems. Indeed, approximately 75 million units of whole blood (~34 million liters) are annually collected worldwide for processing and eventual transfusion...
Chronic Inflammation Gene May Destroy Tumors
5/28/2012
A study published ahead of the 13 July print edition in Molecular Cell reveals that researchers at NYU School of Medicine have, for the first time, discovered a single gene that simultaneously controls inflammation and accelerated aging, as well as cancer. Robert J...
