Toxin detection as close as an inkjet printer
If that office inkjet printer has become just another fixture, it's time to take a fresh look at it. Similar technology may soon be used to develop paper-based biosensors that can detect certain harmful toxins that can cause food poisoning or be used as bioterrorism agents. view more (2009-07-14)
Hopkins researchers develop new tool to watch real-time chemical activity in cells
Attempts to identify potential drugs that interfere with the action of one particular enzyme linked to heart disease and similar health problems led scientists at Johns Hopkins to create a new tool and new experimental approach that allow them to see multiple, real-time chemical reactions in living cells. view more (2006-07-24)
New cancer drug hope
Scientists helping to develop the next generation of cancer-beating drugs say they have had a major breakthrough with their latest results. view more (2006-10-27)
Structure of important neurotransmitter regulator determined
Researchers from Virginia Tech and the Brookhaven National Laboratory have solved the structure of an enzyme that is critical in the regulation of the neurotransmitter system in the human brain. view more (2008-02-04)
Johns Hopkins researchers find link between cell's energy use and genome health
While studying how a cell keeps its genetic material intact, scientists at Johns Hopkins got busy alternately knocking out two catalysts vital to managing a yeast cell's energy. view more (2006-07-24)
Enzyme may hold key to new treatment of diabetic kidney disease
Northwestern University Feinberg School of Medicine researchers have found that an enzyme called ACE2 may hold the potential to treat diabetic kidney disease, the most common form of kidney disease. view more (2006-11-08)
New hope for advances in treating malaria
Researchers at the University of Leeds have developed chemicals which kill the most deadly malaria-causing parasite, Plasmodium falciparum -- including those resistant to existing drugs. view more (2009-04-22)
Farmers Could Be Predisposed To Adverse Health Effects Of Sheep Dip (p 763)
A research letter in this week's issue of THE LANCET suggests that some farmers may have a genetic predisposition to the adverse health effects associated with exposure to organophosphates present in sheep dip. Exposure to organophosphates has acute effects on health, but evidence of chronic effects is unclear. An enzyme found in blood... view more... (2002-02-28)
Finding that 1-in-a-billion that could lead to disease
Errors in the genetic code can give rise to cancer and a host of other diseases, but finding these errors can be more difficult than looking for the proverbial needle in the haystack. view more (2007-08-20)
Reactive oxygen species shown essential for development of inner ear's balance machinery
Reactive oxygen species (ROS) are normally produced as a product of metabolism, and, as their name implies, they are highly reactive with surrounding biological components. view more (2006-01-24)
How Montezuma gets his revenge
Every year, about 500 million people worldwide are infected with the parasite that causes dysentery, a global medical burden that among infectious diseases is second only to malaria. view more (2008-06-16)
Flesh-eating bacteria escape body's safety net
Researchers at the University of California, San Diego (UCSD) School of Medicine have discovered that so-called flesh-eating "Strep" bacteria use a specific enzyme to break free of the body's immune system, a finding which could potentially lead to new treatments for serious infections in human patients. view more (2006-02-21)
Night of the living enzyme
Inactive enzymes entombed in tiny honeycomb-shaped holes in silica can spring to life, scientists at the Department of Energy's Pacific Northwest National Laboratory have found. view more (2006-11-29)
Enzyme and vitamin define the yin and yang of asthma
The allergen breathed in by a person with asthma triggers a proteinase or enzyme called MMP7 that activates a cascade of events to prompt an allergic reaction. view more (2009-03-30)
Starve a yeast, sweeten its lifespan
Johns Hopkins researchers have discovered a new energy-making biochemical twist in determining the lifespan of yeast cells, one so valuable to longevity that it is likely to also functions in humans. view more (2009-03-24)
Commercial yeasts upgraded with an enzyme for biofuel production
Eckhard Boles, co-founder of the Swiss biofuel company Butalco GmbH and a professor at Goethe-University in Frankfurt, Germany, has discovered a new enzyme which teaches yeast cells to ferment xylose into ethanol. Xylose is an unused waste sugar in the cellulosic ethanol production process. The researchers have recently filed a patent application... view more... (2009-02-25)
Slowing the racing heart
Researchers at the University of Illinois at Chicago explain in the May 11 issue of Circulation Research how an enzyme acts on the heart's pacemaker to slow the rapid beating of the heart's "fight-or-flight" reaction to adrenaline. view more (2007-05-14)
New compound effectively treats fungal infections
A new mechanism to attack hard-to-treat fungal infections has been revealed by scientists from the biotech company Anacor Pharmaceuticals Inc., California, and the European Molecular Biology Laboratory [EMBL] outstation in Grenoble, France. view more (2007-06-25)
Immune cells from patients with rheumatoid arthritis have prematurely aged chromosomes
Telomeres, structures that cap the ends of cells' chromosomes, grow shorter with each round of cell division unless a specialized enzyme replenishes them. Maintaining telomeres is thought to be important for healthy aging and cancer prevention. view more (2009-03-05)
Toward a less expensive, more convenient treatment of Gaucher's disease
Prospects for eventual development of a less costly and more convenient treatment for Gaucher's disease have brightened with new research findings reported in the May issue of ACS Chemical Biology. view more (2006-05-25)
