Anti-itching drug clemizole shows promise against hepatitis C

The fight against the liver disease hepatitis C has been at something of an impasse for years, with more than 150 million people currently infected, and traditional antiviral treatments causing nasty side effects and often falling short of a cure. Using a novel technique, medical and engineering researchers at Stanford University have discovered a vulnerable step in the virus' reproduction process that in lab testing could be effectively targeted with an obsolete antihistamine.

Scientists view tiny fibers of working muscles in live humans with microendoscopy technique

Using an unusual microscope with a tip the size of a needle, Stanford researchers are now able to look at tiny fibers of working muscles in live humans, with minimum discomfort to the patient-a development patients are sure to welcome.

Radioactive "tag" added to formaldehyde helps monitor body chemistry, disease

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have devised a simple, fast method for adding a radioactive "tag" to formaldehyde, a common organic chemical.

Hypertension, insulin resistance and immune suppression links

Many of the 75 million Americans with essential hypertension also develop diabetes and other complications in addition to their high blood pressure, and researchers have discovered a common molecular mechanism in a strain of rat that explains why such metabolic disorders arise together in mammals.

Quantum dots stop RNA interference in living cells

More than 15 years ago scientists discovered a way to stop a particular gene in its tracks. The Nobel Prize-winning finding holds tantalizing promise for medical science, but so far it has been difficult to apply the technique, known as RNA interference, in living cells.

Clockwork PCR including sample prep

Analysis and diagnosis in a chip format are coming of age, but their practical application has been limited because until now, the sample usually had to be prepared separately and on a nonminiaturized scale.

New concept sends medical images via cellular phones

A process to transmit medical images via cellular phones that has been developed by a Hebrew University of Jerusalem researcher has the potential to provide sophisticated radiological diagnoses and treatment to the majority of the world's population lacking access to such technology.

New research suggests hypertonic, hyperviscous fluids may be better treatment for severe blood loss

Intravenous administration of isotonic fluids is the standard emergency treatment in the U.S. for patients with severe blood loss, but UC San Diego bioengineering researchers have reported improved resuscitation with a radically different approach. Building on earlier studies in humans that have shown benefits of intravenous fluids that are eight times saltier than normal saline, the researchers combined hypertonic saline with viscosity enhancers that thicken blood.

Anticancer siRNA therapy advances, thanks to nanoparticles

Small pieces of nucleic acid, known as siRNAs (short interfering RNAs), can turn off the production of specific proteins, a property that makes them one of the more promising new classes of anticancer drugs in development. Indeed, at least two siRNA-based anticancer therapies, both delivered to tumors in nanoparticles, have begun human clinical trials. Now, three new reports highlight the progress that researchers are making in developing broadly applicable, nanoparticle-enabled siRNA anticancer therapeutics.
