Ingenium publishes biological characterization of first mouse model for kidney stones

...ent models because it is the result of single base pair substitutions in the gene, which produces a phenotype closely representing a human disease state," stated Michael C. Nehls, M.D., Ph.D., Chief Executive Officer at Ingenium. "The publication underscores the value of our models for biomedical research...

Honeybee gene find ends 150-year search

...e by the two different versions of csd in a female pair up to form a single unit which acts on the next step in sex determination, probably by affecting the expression of other genes. If only one type of csd is made, no active protein is formed and the bee grows into a male. "The csd gene is the major inv...

Scientists at TSRI create new strain of yeast with 21-amino acid genetic code

... functionally "orthogonal" pair--a tRNA/synthetase pair that react with each other but not with endogenous yeast pairs. They then devised a methodology to evolve the specificity of the orthogonal synthetase to selectively accept unnatural amino acids. They created a library of yeast cells, each encoding a...

Scripps team part of collaboration that reveals first ecological genomic 'blueprints'

...ing they were there to suddenly knowing every base pair of DNA." (Prochlorococcus was discovered even later, in 1988.) Palenik believes such marine genomic information will help in the long run in understanding biodiversity and its conservation. "We've always been trying to understand how diverse our pl...

Protein that fights bacteria and viruses cloned by Scripps scientists

.... They mapped the Lps2 mutation to a 216,000-base pair region of chromosome 17. Of the eight genes in that region, one gene, then called Trif, was a prime candidate because it encoded an adaptor "TIR domain" protein--just the type of protein that might participate in signaling from toll-like receptors. ...

Researchers zero in on new drug combination strategy

...to rapidly identify combinations of compounds that pair synergistically to produce a desired therapeutic effect. Remarkably, the researchers identified several novel pairings with significant therapeutic promise, including a new combination that kills an infectious, drug-resistant strain of the yeast Can...

New finding has implications for scientists designing mobile audio interfaces

"Currently humans adapt to the limitations of computers," said Oviatt. "But future computers need to be more adaptive to us. They should be sma...

Rumors of male chromosomes demise greatly exaggerated, study finds

... pairs except the Y. Each member of a chromosomal pair draws on its mate for genetic repair through sexual recombination. When one half suffers a genetic injury, as is the case with many diseases, it can discard the mutated gene and replace it with a normal copy drawn from the other member of the pair. B...

First-ever images of developing dengue virus obtained at Purdue

...more than 24,000 people in the world annually. The pair solved the structure of the mature dengue virus particle last year (see related story), and Rossmann said the new findings were a significant step toward unraveling the behavior of viruses. "We're beginning to dissect the individual steps in a virus...

Finished Y-chromosome sequence reveals a genomic 'crystal palace'

... and the much smaller Y chromosome. Females have a pair of X chromosomes and males have both an X and Y chromosome. Although the sequences of several organisms with Y chromosomes -- including fruit flies and mice -- have been declared "complete," said Page, those genome sequences did not include the Y chr...

PISCO, a program supported by a pair of five-year grants totaling $20 million from the David and Lucile Packard Foundation, is studying the near-shore region of the Pacific Coast. OSU is one of four universities in the initiative, which Lubchenco says is a prototype for large-scale mari...

Novel flu vaccine shows promise in mice

...rrent flu vaccines trigger an immune response to a pair of prominent viral-coat proteins that mutate constantly, which is the reason last year's flu vaccine is ineffective against this year's flu strains. The experimental vaccine contains an engineered peptide that mimics a third, smaller viral-coat prote...

Laser tweezers capture microscopic particles in a fluid by using a tightly focused light beam. Raman spectroscopy can obtain a highly unique "fingerprint" for each substance by...
