Two novel radiolabeled small molecules targeting prostate-specific membrane antigen (PSMA) have excellent potential for further development as diagnostic and therapeutic radiopharmaceuticals, according to research published this month in The Journal of Nuclear Medicine. The imaging agents—123I-MIP-1072 and 123I-MIP-1095—were shown to have a high sensitivity of lesion detection in bone, soft tissue and the prostate gland with minimal retention in non-target tissue. http://medicalxpress.com/news/2013-03-small-molecules-visualize-prostate-cancer.html Cancer Tue, 05 Mar 2013 11:05:12 EST news281703906 (HealthDay)—For women at higher risk for ovarian and/or fallopian tube cancer (OC/FTC), annual screening offers high sensitivity for detection of incident cancers, but few of these cancers are stage I or II, according to research published online Dec. 3 in the Journal of Clinical Oncology. http://medicalxpress.com/news/2012-12-strict-ovarian-ca-screening-adherence.html Cancer Wed, 05 Dec 2012 16:40:02 EST news273946539 Danish researchers have developed a new and sensitive method that makes it possible to diagnose malaria from a single drop of blood or saliva. The method might eventually be used in low-resource areas without the need for specially trained personnel, expensive equipment, clean water or electricity. With the development of this method, the researchers hope to go one step further in identifying and treating all patients suffering from malaria. http://medicalxpress.com/news/2012-11-method-malaria.html Medical research Tue, 27 Nov 2012 09:56:52 EST news273232601 A new noninvasive test for colorectal cancer screening demonstrated high sensitivity for detecting colorectal cancer, in particular precancers that are most likely to develop into cancer, according to data presented at the 11th Annual AACR International Conference on Frontiers in Cancer Prevention Research, held here Oct. 16-19, 2012. http://medicalxpress.com/news/2012-10-noninvasive-colorectal-cancer.html Cancer Tue, 16 Oct 2012 13:30:42 EST news269612998 (Medical Xpress)—Scientists funded by the British Heart Foundation (BHF) at the University of Dundee have found that a combination of blood tests could effectively pick up 'silent' heart disease in thousands of people.

High sensitivity and high specificity, however, are frequently a challenge to achieve with these methods. In a study scheduled for publication in the November issue of The Journal of Molecular Diagnostics, researchers describe a new, robust technique that holds promise for identifying trace mutant DNA sequences (signals) in an overwhelming population of unmutated DNA (noise). http://medicalxpress.com/news/2011-10-method-mutant-dnas.html Medical research Tue, 11 Oct 2011 12:06:31 EST news237553584
