Modified mushrooms may yield human drugs

.... "Mushrooms could make the ideal vehicle for the manufacture of biopharmaceuticals to treat a broad array of human illnesses. But nobody has been able to come up with a feasible way of doing that." Dr. Romaine and his colleague, Xi Chen, then a post-doctoral scholar at Penn State and now a Syngenta Biote...

A new portable biosensor detects traces of contaminants in food more quickly and cheaply

...an be extended on an industrial scale to allow the manufacture of large quantities at a very low cost, and may even be made for personal, disposable use . The chemical mechanism to detect contaminants in a sample is very similar to that used by the immune system to identify a virus or bacteria in the body. T...

Get a whiff of this: Smell test could sniff out serious health problems

...nics Company in Stillwater, Minn. The company will manufacture and market the test. The Sniff Magnitude Test project, a creation that was seven years in the making, was awarded a total of $1,340,098 from the National Institutes of Health in developmental funding. UC Psychology Professor Robert Frank says that ...

With this outstanding team, we can truly focus on achieving the greatest ben...

Blood sugar's manufacture limited by building blocks' supply

...ve discovered a factor that controls blood sugar's manufacture in a novel way: by limiting the supply of its building blocks. The findings are reported in the April issue of the journal Cell Metabolism, published by Cell Press. The study found that mice deficient for KLF15, a member of the so-called Krüppel-lik...

Chemo combination improves survival in asbestos-related cancer

...ailway engineering, construction work and asbestos manufacture have higher rates of mesothelioma than the general public. The cancer may take 10 to 60 years to develop, and the risk does not diminish after exposure to asbestos has stopped. Family members of people exposed to asbestos at work also have an increa...

Turning green gunk to gold, anti-cancer gold

... enzymes and developing a new, efficient method to manufacture the broad class of cryptophycin natural products, including important analogs with clinical potential. This included characterization of an enzyme, cytochrome P450, that always introduces the epoxide in the desired beta configuration. Sherman, who...

Researcher examines polymers created with poultry feathers

...like petroleum-based plastics. They are cheaper to manufacture and meet or exceed most properties except for water resistance and longevity. Meeting these performance requirements is a challenge, Barone explains. Barone is taking his lead from nature to find potential solutions to these performance requiremen...

New drug blocks influenza, including bird flu virus

...and it can take as long as a year to formulate and manufacture vaccine in quantity. Antiviral drugs, it is anticipated, would be used to buy time to produce a vaccine in the event of a flu pandemic. And one intriguing possibility, the Wisconsin scientists add, is that the drug might be able to help stimulate a...

Five new technologies that promise to transform medicine

...to isolate cancer cells, fabrication technology to manufacture customised body parts, and the use of miniature robots to track and destroy infections before they cause disease. The individual and collective impact of these technologies is already present in some aspects of contemporary medicine and the rate o...

MIT creates 3-D scaffold for growing stem cells

...ze to the extracellular matrices that living cells manufacture themselves. Adding motifs With the addition of defined amino acid fragments called active motifs, the scaffold can be fashioned to coax stem cells to behave in certain desirable ways-such as differentiating into needed body tissues or migrating...

A transplant in time

Everything we do focuses on achieving the grea...

Bacteria could make new library of cancer drugs that are too complex to create artificially

...f Warwick are examining a way of using bacteria to manufacture a new suite of potential anti-cancer drugs that are difficult to create synthetically on a lab bench. The bacterium Streptomyces coelicolor naturally produce antibiotics called prodiginines. This group of antibiotics has stimulated much recent in...

Hair samples show babies can be exposed to 'crystal meth' while in the womb

...viour and aggression. The drug is very easy to manufacture in home laboratories, and global use has soared, particularly among young women, say the authors. An estimated half a million Americans alone are thought to use it every week, including 5% of pregnant women. The authors carried out hair sample an...

Normally, the capsid protein is clipped apart from a major structural protein called the gag protein, and is then assembled into a cone. PA-457 stops it being clipped off, causing it to form a leaky sphere that ...

Microbes transform 'safest' PBDEs into more harmful compounds

...e real world, raising concerns about the continued manufacture and use of deca-BDEs, Alvarez-Cohen says. In their study, Alvarez-Cohen and her colleagues exposed octa-BDE and deca-BDE to five types of anaerobic bacteria commonly found in the soil. Based on previous research with other compounds, they anticipated...
