As many as 50 percent of all human protein-coding genes are regulated by microRNA (miRNA) molecules. While some miRNAs impact onset and progression of cancer, others can actually suppress the development of malignant tumors and are useful in cancer therapy. They can also serve as potential biomarkers for early cancer detection. In a new issue of Cancer Biomarkers, investigators report on non-coding miRNAs as appealing biomarkers for malignancy. http://medicalxpress.com/news/2012-12-micrornas-opportunities-cancer-therapy-diagnosis.html Cancer Wed, 19 Dec 2012 17:54:23 EST news275162056 Scientists at the Johns Hopkins Kimmel Cancer Center have combined the ability to detect cancer DNA in the blood with genome sequencing technology in a test that could be used to screen for cancers, monitor cancer patients for recurrence and find residual cancer left after surgery. http://medicalxpress.com/news/2012-11-scientists-pair-blood-gene-sequencing.html Cancer Wed, 28 Nov 2012 14:46:47 EST news273336399 (Medical Xpress)—Virginia Commonwealth University School of Nursing researchers have discovered that guided imagery significantly decreases stress, fatigue, pain and depression in women with fibromyalgia. http://medicalxpress.com/news/2012-11-imagery-symptoms-fibromyalgia.html Diseases, Conditions, Syndromes Mon, 19 Nov 2012 08:00:03 EST news272532989 Uganda on Thursday declared an outbreak of the deadly Ebola virus that killed 17 people dead to be over, officials said. http://medicalxpress.com/news/2012-10-uganda-ebola-outbreak.html Diseases, Conditions, Syndromes Thu, 04 Oct 2012 11:41:43 EST news268569603 Uganda's latest outbreak of the deadly Ebola virus appears to be over, the World Health Organisation said Monday, pointing out that no new cases had been confirmed for the past month. http://medicalxpress.com/news/2012-09-uganda-ebola-outbreak.html Diseases, Conditions, Syndromes Mon, 03 Sep 2012 10:53:57 EST news265888410 A new paper by Crislyn D'Souza-Schorey, professor of biological sciences at the University of Notre Dame, discusses the biology of tumor-derived microvesicles and their clinical application as circulating biomarkers. Microvesicles are membrane-bound sacs released by tumor cells and can be detected in the body fluids of cancer patients. http://medicalxpress.com/news/2012-06-biology-tumor-derived-microvesicles.html Cancer Thu, 21 Jun 2012 15:42:48 EST news259512133 The strategy used by Google to decide which pages are relevant for a search query can also be used to determine which proteins in a patient's cancer are relevant for the disease progression. Researchers from Dresden University of Technology, Germany, have used a modified version of Google's PageRank algorithm to rank about 20,000 proteins by their genetic relevance to the progression of pancreatic cancer. In their study, published in PLoS Computational Biology, they found seven proteins that can help to assess how aggressive a patient's tumor is and guide the clinician to decide if that patient should receive chemotherapy or not. http://medicalxpress.com/news/2012-05-google-cancer-algorithm-biomarkers.html Cancer Thu, 17 May 2012 17:05:36 EST news256493125 An inexpensive new medical sensor has the potential to simplify the diagnosis of diseases ranging from life-threatening immune deficiencies to the common cold, according to its inventors at the Stanford University School of Medicine. http://medicalxpress.com/news/2012-03-immune-system-sensor-slash-disease.html Medical research Wed, 07 Mar 2012 10:46:58 EST news250339606 (Medical Xpress) -- Do you remember the scenes from your favorite Star Trek episode where Dr. McCoy simple waves his scanner across an injured patient to diagnose the problem?
