New study sheds light on most common and deadly form of brain cancer
1/13/2014
Glioblastoma (GBM) is the most common and deadly form of primary malignant brain cancer accounting for approximately 15% of all brain tumours and occurring mostly in adults between the ages of 45 and 70. The aggressive recurrent nature of this cancer is only temporarily contained by combined surgery, chemotherapy and radiation treatment.
Negative feedback makes cells 'sensitive'
1/13/2014
New research has shown that negative feedback loops in cell signalling systems can be essential for a cell's ability to perceive the strength of a growth stimulus. Cells lacking the feedback loop became insensitive to the level of the stimulus in a manner similar to a cancerous cell displaying unrestrained growth.
Racial differences in cosmetic outcomes after breast-conserving therapy
1/13/2014
As perceived by both patients and doctors, the cosmetic results after "lumpectomy" for breast cancer differ for African-American versus Caucasian women, suggests a pilot study in the Plastic and Reconstructive Surgery - Global Open®, the official open-access medical journal of the American Society of Plastic Surgeons (ASPS).
Ovarian cancer biomarker discovered
1/13/2014
Researchers at Case Western Reserve University have identified a microRNA biomarker that shows promise in predicting treatment response in the most common form of ovarian cancer - a breakthrough that has the potential to improve outcomes for patients with the disease.
Detecting cervical cancer using simple test
1/12/2014
Researchers at the University of Louisville have confirmed that using the heat profile from a person's blood, called a plasma thermogram, can serve as an indicator for the presence or absence of cervical cancer, including the stage of cancer.The team, led by Nichola Garbett, Ph.D., published its findings in PLOS ONE.
Study reveals major role of RNA polymerase and other enzymes in DNA repair
1/12/2014
Our health depends in large part upon the ability of specialized enzymes to find and repair the constant barrage of DNA damage brought on by ultraviolet light radiation and other sources. In a new study NYU School of Medicine researchers reveal how an enzyme called RNA polymerase patrols the genome for DNA damage and helps recruit partners to repair it.
Pregnancy exposure to BPA in plastic 'raises prostate cancer risk'
1/10/2014
A study in mice has found prostate cancer is more likely to develop when exposure to BPA levels matches that typical for pregnant women, according to researchers from the University of Illinois at Chicago (UIC) investigating concerns over the chemical used in water bottles.
New blood test 'could accurately predict heart attack risk'
1/10/2014
According to The Heart Foundation, more than 920,000 Americans will suffer a heart attack this year, and many of these will occur without warning. But researchers from The Scripps Research Institute in California say they have created a blood test which may be able to predict whether patients are at high risk of heart attack.The research team, led by Prof.
FDA clearance of automated Direct Renin assay on the IDS-iSYS system
1/10/2014
Immunodiagnostic Systems Holdings plc ("IDS" or '"the Company") announces that it has received USA FDA (Food and Drug Administration) clearance for its Direct Renin assay for use on its IDS-iSYS system, enabling IDS to enter the US market with this product. The IDS-iSYS Direct Renin immunoassay is used to determine the amount of active renin present in the blood.
Patients with metastasized melanoma may benefit from new diagnostic and therapeutic techniques
1/10/2014
With low survival rates for patients with metastasized melanoma, accurate staging and effective treatments are critical to extending life. New research published in The Journal of Nuclear Medicine highlights the potential of newly developed radiopharmaceuticals with benzamide for the imaging of metastases and as a targeted systemic therapy.
