Breast cancer and hormone therapy -- A looking-glass mirror?

...ust be drawn with great caution. It is tempting to simplify the observed year-by-year figures on HT use and breast cancer incidence and establish a mirror glass equation: the more postmenopausal hormone use, the more breast cancer, and vice versa. But human biology is far too complicated and the pathophysiolo...

By integrating all known human, mouse and rat genes and proteins into one database, the iGene search engine helps scientists quickly filter through more than 250,000 p...

UA researchers find smallest cellular genome

...one species of endosymbiotic bacteria, which would simplify the genomic analysis. The researchers collected Pachypsylla venusta psyllids from hackberry trees (Celtis reticulata) on the UA campus and around Tucson. The team extracted the Carsonella DNA and sequenced it. Even though endosymbionts need fewe...

Images develop clinical applications for new DESI technology

...commonly used in biological sciences, to speed and simplify the time-consuming and labor-intensive analytical process, Ifa said. Mass spectrometry works by first turning molecules into ions, or electrically charged versions of themselves, so they have mass and can be detected and analyzed. The DESI procedure...

NHGRI aims to make DNA sequencing faster, more cost effective

The potential of translational research is clear. UCSF and Stanford University scientists co-discover...

High-value chemicals produced from ethanol feedstocks could boost biorefinery economics

...luids, such as carbon dioxide under high pressure, simplify separation processes. Separation of the carbon dioxide from chemicals dissolved in it requires only that the pressure be reduced, allowing the CO2 to return to its gaseous state. Though many challenges remain before biorefineries can be designed a...

New methods for screening nanoparticles

...eveloped by the Brookhaven team, are an attempt to simplify the research by eliminating many of the variables found in animal studies, giving researchers greater control over experimental conditions.

...veries. "What we wanted to do was miniaturize and simplify testing," said Kricka. "These chips can be used at the point-of-care in a doctor's office or in the field for bio-terrorism tests, which is one of the main ways they are being used. There are a lot of potential uses for them." Although Dr. Kricka has...

Groovy protein essential for promoting cancer development

...Scientists from Cech's lab and others had tried to simplify matters by crystallizing a portion of the protein, but the segments that they selected clumped together just as stubbornly as the whole enzyme. Jacobs, a Damon Runyon Cancer Research Foundation fellow in Cech's lab and the first author of the paper,...
