Brown University researchers have created a reliable and fast flu-detection test that can be carried in a first-aid kit. The novel prototype device isolates influenza RNA using a combination of magnetics and microfluidics, then amplifies and detects probes bound to the RNA. The technology could lead to real-time tracking of influenza. Results are published in the Journal of Molecular Diagnostics.

PROVIDENCE, R.I. [Brown University] — In April 2009, the world took notice as reports surfaced of a virus in Mexico that had mutated from pigs and was being passed from human to human. The H1N1 “swine flu,” as the virus was named, circulated worldwide, killing more than 18,000 people, according to the World Health Organization. The Centers for Disease Control and Prevention in the United States said it was the first global pandemic in more than four decades. (more…)

*Proprotein convertases are enzymes that activate many essential proteins, but they are also implicated in many processes that cause disease. In a research review in the New England Journal of Medicine, Andrew Artenstein and Steven Opal argue that proprotein convertases are potentially rich targets for developing therapies.*

Most people have never heard of proprotein convertases, but the enzymes activate many proteins that are essential for life. Unfortunately, their fundamental role puts them in the middle of many processes that cause disease – not just cancer or athlerosclerosis, but both of those and Alzheimer’s and anthrax and the flu and an amazing variety of other maladies.

In a research review article appearing Dec. 29 in the New England Journal of Medicine, Andrew Artenstein, physician-in-chief in the Department of Medicine at Memorial Hospital, and Steven Opal, chief of infectious diseases at Memorial Hospital, argue that proprotein convertases (PCs) are potentially rich targets for developing therapies. Artenstein, who with Opal is on the faculty of the Warren Alpert School of Medicine, explained PCs to David Orenstein. (more…)
