World's Oldest Human Tumor Discovered - Over 120,000 Years Old
6/07/2013
Researchers have just discovered the world´s oldest tumor, in the rib of a 120,000 year old Neanderthal in Croatia. It is a very rare discovery considering that tumors were uncommon in prehistoric populations. Tumors in fleshy tissue decay quickly - making them difficult to identify. Spelling: both "Neandertals" and "Neandertals" are correct...
New Plug-In Optical Sensor For Smartphones Could Diagnosis Kaposi's Sarcoma In The Field
6/07/2013
As antiretroviral drugs that treat HIV have become more commonplace, the incidence of Kaposi's sarcoma, a type of cancer linked to AIDS, has decreased in the United States. The disease, however, remains prevalent in sub-Saharan Africa, where poor access to medical care and lab tests only compound the problem...
Researchers Uncover Genetic Key For Improved Blood-Thinning Therapy For African-American Patients
6/06/2013
Researchers have discovered a way to make a blood thinner safer for about 40 percent of African-Americans taking the drug by linking a common gene variation to the dose...
Variations From State To State In Rates Of Emergency Bowel Surgery
6/06/2013
Johns Hopkins researchers have documented huge and somewhat puzzling interstate variations in the percentage of emergency versus elective bowel surgeries. Figuring out precisely why the differences occur is critical, they say, because people forced to undergo emergency procedures are far more likely to die from their operations than those able to plan ahead for them...
Improved Understanding Breast Cancer Stem Cells
6/06/2013
A joint project between the Griffith University and the UQ Centre for clinical Research (UQCCR) has characterised an in vitro model that allows further studies on the breast cancer biology. These studies include the confirmation that primary tissue obtained from patients with breast cancer behaves similarly to those derived from long-term cultured cell lines...
Discovery Of A New Oncogene And Target In Lung Cancer
6/06/2013
Adding to the list of oncogenic drivers of lung cancer that includes ALK, EGFR, ROS1 and RET, results of a University of Colorado Cancer Center study presented at ASCO 2013 show that mutations in the gene NTRK1 cause a subset of lung cancers. "We're reconceptualizing lung cancer as many, related diseases. And we need to learn to identify and treat each individually...
Potential Biomarker Identified For Aggressive Colon Cancer
6/06/2013
MET protein levels correlate strongly with epithelial-mesenchymal transition (EMT) phenotype, a treatment-resistant type of colorectal cancer and may be used as a surrogate biomarker, according to new research from The University of Texas MD Anderson Cancer Center...
Test Developed To Identify Unsafe Stem Cells
6/06/2013
The breakthrough is a significant step in improving the quality of iPS cells and identifying unwanted cells that can form tumours. The test also determines how stable iPS cells are when grown in the lab. Dr Andrew Laslett and his team have spent the last five years working on the project. The research has focused on comparing different types of iPS cells with human embryonic stem cells...
Discussing Death With Patients The Most Stressful Part Of Oncology
6/06/2013
A group of oncologists have revealed in a new study by Ben-Gurion University of the Negev (BGU) researchers that communicating about death and dying with their patients is one of the most difficult and stressful parts of their work. In the United States, 577,190 deaths from cancer occurred in 2012, according to the American Cancer Society...
New Class Of Molecules May Be Key To Emerging 'Enhancer Therapy'
6/06/2013
In a pair of distinct but complementary papers, researchers at the University of California, San Diego School of Medicine and colleagues illuminate the functional importance of a relatively new class of RNA molecules...
