WALTHAM, Mass., June 16, 2014 – Alere Inc. (NYSE: ALR), a leading global provider of point-of-care rapid diagnostic and health information solutions, today announced that it has received clearance from the U.S. Food and Drug Administration (FDA) for the Alere™ i Influenza A & B test, the first and only molecular test to detect and differentiate influenza A and B virus in less than 15 minutes. …
Molecular testing involves the extraction and analysis of DNA or RNA strands to detect sequences associated with viral and bacterial causes of infections. Alere i Influenza A & B is the first molecular diagnostic test that delivers actionable, lab-accurate results in less than 15 minutes on a user-friendly platform. Unlike polymerase chain reaction (PCR) testing, Alere’s proprietary Molecular. In Minutes™ (MIM) isothermal nucleic acid amplification technology (iNAT) does not require lengthy and complex thermo cycling or DNA purification, and can therefore deliver PCR-caliber results more quickly – and in a broad range of settings. Alere i tests for Strep A, C. difficile, respiratory syncytial virus (RSV) and chlamydia / gonorrhea are currently in development. The complete press release can be found here.

An antibody and toxin mix has successfully detected and killed HIV-infected cells lurking in the organs and bone marrow of mice that were altered to have a human immune system. The results, reported Thursday in the online journal PLOS Pathogens, offer conceptual proof that a reservoir of HIV-infected cells in organs can sought out and destroyed, a scenario that would potentially end the stalemate between the virus and antiretroviral drug therapies.
NEW YORK (GenomeWeb News) – The New York Genome Center (NYGC) and the University of Buffalo (UB) have received $105 million in state funding to work together in pursuing genomic medicine advances and computational biomedical research, NYGC and UB said today.
The funding, which New York Gov. Andrew Cuomo unveiled in his “State of the State” remarks [January 9th], will provide $55 million to NYGC and $50 million to the University of Buffalo to create the NY Genomic Medicine Network. Rest
A new advance in the use of nanoparticles to deliver medicine or other therapeutics orally is described in a short summary in a Wall Street Journal article or a longer, more detailed news release from MIT. Not surprisingly Professor Robert Langer is an author on the paper appearing in the Nov. 27 online edition of Science Translational Medicine. In a classic example of looking to nature to show the way, the researchers looked at previous work on how babies absorb antibodies from their mothers’ milk, and then built nanoparticles that are selectively passed through the intestinal barrier using protein coats that are recognized by receptor sites in the intestinal lining.
The research was funded by a Koch-Prostate Cancer Foundation Award in Nanotherapeutics; the National Cancer Institute Center of Cancer Nanotechnology Excellence at MIT-Harvard; a National Heart, Lung, and Blood Institute Program of Excellence in Nanotechnology Award; and the National Institute of Biomedical Imaging and Bioengineering.
In a strategy known as gene therapy, scientists insert engineered DNA into diseased cells in order to treat or kill them. Now, researchers have combined nanotechnology and synthetic biology to create a simple switch to turn on such genes inside cells. They demonstrate that heat generated by magnetic nanoparticles activates the engineered genes, slowing tumor growth in mice (ACS Synth. Biol. 2013). REST
Here’s an interesting idea. The threat from viral pathogens such as bird flu, hepatitis B and HIV, represents a clear and present danger. So cheap and simple tools for detecting these viruses are much needed, particularly in the developing world where the threat is acute but money scarce.
Step forward Jaeoh Shin and pals at the University of Potsdam in Germany who say that it is possible to create just such a virus detector using little more than a few strands of DNA mixed into a lump of hydrogel. This ‘intelligent’ blob would shrink when the virus in question was around giving a clear visible signal that precautions need to be taken. REST
Leuven (Belgium) October 24, 2013 - Researchers and physicians at Johns Hopkins University will collaborate with the nanoelectronics R&D center imec to advance silicon applications in healthcare, beginning with development of a device to enable a broad range of clinical tests. The corresponding tests will be performed outside the laboratory. The collaboration, announced today, will combine the Johns Hopkins clinical and research expertise with imec’s nanoelectronics capabilities. The two organizations plan to forge strategic ties with additional collaborators in the healthcare and technology sectors.
“Johns Hopkins has always prioritized innovative and transformative research opportunities,” said Landon King, MD, the David Marine Professor of Medicine and executive vice dean of the school of medicine. “Our new collaboration with imec is such an opportunity, and we very much look forward to leveraging our respective strengths across the university in biomedical and nanotechnology research to improve patient diagnosis and care throughout the world.”
Imec and Johns Hopkins University hope to develop the next generation of “lab on a chip” concepts based on imec technology. The idea is that such a disposable chip could be loaded with a sample of blood, saliva or urine and then quickly analyzed using a smartphone, tablet or computer, making diagnostic testing faster and easier for applications such as disease monitoring and management, disease surveillance, rural health care and clinical trials. Compared with the current system of sending samples to a laboratory for testing, such an advance would be “the healthcare equivalent of transforming a rotary telephone into the iPhone,” said Drew Pardoll, MD, PhD, the Martin Abeloff Professor of Oncology. Pardoll leads the advisory board for the Johns Hopkins-imec collaboration, which will work to extend new applications of silicon nanotechnology into multiple areas of medicine.
“This relationship with Johns Hopkins is an important step toward creating a powerful cross-disciplinary ecosystem with consumer electronics and mobile companies, medical device manufacturers, research centers and the broader bio-pharma and semiconductor industries, to create the combined expertise required to address huge healthcare challenges that lie ahead,” stated Luc Van den hove, CEO at imec. “Only through close collaboration will we be able to develop technology solutions for more accurate, reliable and low-cost diagnostics that pave the way to better, predictive and preventive home-based personal health care.” REST
