Bacteria are key to 'green' plastics, drugs

...the rate -- the speed of the conversion -- and the yield -- the amount of succinate produced per pound of glucose converted. Bennett and San's bug -- known only by the designation SBS550MG -- contains an ingenious bit of metabolic engineering that allows it to produce succinate in two different ways. One ...

Unexpected lock and key mechanism found for the assembly of tumor blood vessels

...rmation of new blood vessels. The work also could yield new ways to diagnose and combat cancer. In fact, together with Barbara Parker, M.D., UCSD Professor of Clinical Medicine at the Moores UCSD Cancer Center, the researchers currently are conducting tests with breast cancer patients to see if measuring ...

Scientists discover the body's marijuana-like compounds are crucial for stress-induced pain relief

...rgia and the University of California, Irvine, may yield a target for new drug therapies that will completely bypass the current arguments over the use of medical marijuana. In theory, the new research makes it possible to design a pill that will have the same pain relieving effects as smoked marijuana, bu...

Deep thinking: Scientists sequence a cold-loving marine microbe

... that deciphering C. psychrerythraea's genome will yield insights into another cool character, its namesake. Deming, who led the establishment of the Colwellia genus, named the genus after her one-time advisor: noted marine biologist Rita Colwell. In addition the TIGR team, led by Methé, study collaborato...

Brain Scan Study of Smokers Reveals Signature of Craving

...aid. What's more, they added, such brain scans may yield diagnostic tests for predicting which smokers will benefit most from particular quitting methods. The team reported its results in an article in the journal Neuropsychopharmacology that is now online and which will be published in print in a forthco...

Unique library of plant genes germinates, takes root at UNC

... those kinds of questions will lead to plants that yield more food and resist damage from diseases and insects more successfully, he said. They also can lead to better and cheaper medicines and plant products like cotton, paper and rubber. "A persistent challenge of genomics is how to capture, analyze and...

Tamoxifen-like drug suggests new ways to selectively block estrogen

... SERM or SERD or other endocrine therapy that will yield maximal benefit in the clinic." New tools such as the Advanced Photon Source at Argonne National Laboratories are making this sort of once-grandiose plan more realistic, Greene said. "We used to solve the structures of one or two molecules a year. N...

Searching the depths of the straits of Florida for disease cures

...l likelihood making for a unique habitat that will yield numerous interesting and potentially lifesaving samples during submersible dives as deep as 3,000 feet. The team will also conduct daily scuba dives in search of shallow-water organisms for biomedical testing. Though Harbor Branch has used its subme...

Sponges as drugs

...ge-scale production of useful substances if it can yield large quantities of the sponge species. Therefore, sea rearing would only seem to be a profitable option if the quantities of the substance needed are small or if the growth can be optimised in combination with other reared organisms. Nicole de Voog...

DOE JGI launches IMG public online microbial genome data clearinghouse

...ple species selected from the organism browser may yield clues of what its role might be in your particular species," said Andersen. "The interface is quite intuitive, which is a benefit for someone like me that does not like to read manuals." John Taylor, professor of plant and microbial biology at UC Be...

Secret of smallpox's success may lead to bioterror cure

... is on a fast-track, with the studies projected to yield a usable vaccine virus within eighteen months. At that point, the virus will go to a commercial manufacturer, who will be responsible for developing and then producing a complete nasal-delivery vaccine. If all is successful, a large number of doses w...

NIH Researchers Discover How Insulin Allows Entry of Glucose Into Cells

...ich the vesicles fuse with the cell membrane might yield a new drug to treat insulin-related disorders. He added that each step in the process might provide the basis for a treatment: when the vesicles first stop moving, when they tether to the inside of the cell’s membrane, and when they fuse with the mem...

Bioelectronic ‘signatures?hold key to DNA mutations

...nocrystals were selected owing to their ability to yield distinct electronic signatures, with four well-resolved current peaks. Next, the nanocrystals are piggybacked onto individual DNA bases; these DNA bases ?each carrying a single nanocrystal ?bind to a DNA sample and cause minute electrical current cha...

Sickle cell and protection against malaria

... older children. Research into malaria has yet to yield an effective vaccine but this work may provide some insights for such research. The authors suggest mechanisms by which HbAS could affect immunity, for example, accelerated acquisition of antibodies to altered host proteins expressed on the malaria-i...

Researchers make gains in understanding antibiotic resistance

...ir studies because they crystallize well enough to yield high-resolution structural data, but these ribosomes, like those from eukaryotes, are resistant to most MLSBK antibiotics. The researchers analyzed the structure of erythromycin ?among the most widely prescribed macrolide antibiotics ?bound to a mut...

Glow-in-the-dark zebrafish at UH hold keys to biological clocks

...earchers used zebrafish (danio rerio) because they yield such a high output of spawn, with hundreds of eggs being laid by each female per week. This gives the scientists a better chance of identifying mutant fish whose biological clocks run fast or slow, providing the ability to trace the specific genes th...

Scientists discover how plants disarm the toxic effects of excessive sunlight

...tive pathway, "we could be able to get larger crop yield per photon of light," he says. And by making cells more resistant to singlet oxygen, scientists may be better able to design bioenergy systems that use sunlight as an alternative to traditional fossil fuels. "By understanding how biology solves this...

New Drugs For Bad Bugs: UF Approach Could Bolster Antibiotic Arsenal

...sted in clinical trials are adequate and likely to yield good results, said Dr. William Craig, a professor of medicine at the University of Wisconsin, adding that until now, “many, many antibiotics that initially came out have either had their dosages changed because they were excessive or had them increas...

Genetically modified rice in China benefits farmers' health, study finds

...ers reduce pesticide use in the fields, increasing yield and having any identifiable health effects on the farmers growing the genetically modified rice strains. They examined data from field trials involving two genetically modified rice strains: the Xianyou 63, created to be resistant to rice stem borer...

Kinovate Life Sciences Launches Nittophase?High Performance Solid Support For Oligonucleatide Synthesis

...tly lower unit cost, as well as potentially higher yield and full length purity, reducing cost-of-goods. NittoPhase?will be commercially available in two grades; NittoPhaseTOS?for high loading applications, and NittoPhaseROS?for lower loading applications. In this way, NittoPhase?offers a solution for the ...
