Proteins may predict lung transplant rejection

...nformatics (the use of computers and statistics to analyze and find patterns in scads of data). They hypothesized that proteins would change as chronic lung rejection developed and that the new technology would make it possible to find these patterns from among the thousands of proteins at work in the lungs....

A sweet step toward new cancer therapies

...ly weighs molecules or fragments of molecules---to analyze proteins. In this process, proteins are introduced into the mass spectrometer and fragmented by heating until the weakest bonds break. "It's the 'shake-it-til-it-breaks' approach," Hakansson said. Together, the masses of the various fragments pro...

New science of metagenomics 'will transform modern microbiology'

... the computational and algorithmic methods used to analyze the data. ...

Pacific Rim researchers to collaborate on distributed bioinformatics analysis of avian flu

...the integrated Genome Analysis Pipeline (iGAP), to analyze avian flu genomes. (The iGAP suite of bioinformati...nces, University of Hawaii. "This will allow us to analyze the biosynthetic pathways of viruses as well as the signal transduction pathways for clues to unders...

Gene hunters close in on Lou Gehrig’s disease

...chers used a new technology known as “SNP chips?to analyze all 555,352 SNPs in the genome of each subject. SNP chips are glass slides that resemble computer processor chips. They’re coated with tiny beads that “read?the SNPs scattered throughout the human genome. The researchers found 34 genetic variants ...

Like salty food? Chances are you had low blood sodium when you were born

...VA, correlational analysis (Spearman), and SPSS to analyze the data. Alpha was fixed at 0.05 and SEM was the measure of variability. The Study: Results Upon review of the data, the researchers concluded that: reported dietary sodium consumption in childhood (ages 8-15) was predicted by neo...

Computer imaging assists with facial reconstructive surgery

...It is essential for plastic surgeons to accurately analyze the face before surgery so that afterward, prominent facial features such as the chin and nose are balanced in relation to the structures around them. “Even a well-executed surgery will result in a poor aesthetic result if inaccurate analysis leads ...

Study uncovers a lethal secret of 1918 influenza virus

...ctional genomics, a technique in which researchers analyze the gene functions and interactions. Learning more about the virulence mechanisms of the 1918 flu virus may help researchers understand how to keep the virus from causing such a severe immune response. "This study in macaques, combined with our ear...

Scientists create dual-modality microbeads to improve identification of disease biomarkers

..." This new technology allows the researchers to analyze very low concentrations of target molecules. "Instead of analyzing a liter of sample where the concentration could be very dilute and you might not see the target molecule you’re looking for, you can let the beads capture the molecules on their surfa...

Map predicting spread of avian flu

...so identify high-risk areas in the Netherlands and analyze various control strategies, concluding that in these regions an epidemic can only be brought to an end by massive culling of susceptible farms. For avian influenza, the analyses show that there are two poultry-dense areas in The Netherlands where ep...

Homing pigeons get their bearings from their beaks

...ern with different spatial orientation designed to analyze the three components of the magnetic field vector separately. They react to the Earth’s external magnetic field in a very sensitive and specific manner, thus acting as a three-axis magnetometer. The study suggests that the birds sense the magneti...

Scientists sequence genome of parasite responsible for common sexually transmitted infection

...ection. Additionally, the researchers were able to analyze proteins thought to be linked to the parasite's hydrogenosome--its energy source and the target of the two drugs approved to treat trichomoniasis--and identified possible ways the parasite may become resistant to these medications. Understanding how ...

Darwin's famous finches and Venter's marine microbes

...their unique genetic code. The current studies analyze samples collected from surface waters during the first phase (or first third) of the voyage, which led the Sorcerer II from Newfoundland through the Panama Canal and Galapagos Island on to French Polynesia. Venter’s crew siphoned seawater through a s...

New species of snapper discovered in Brazil

... spent five years observing Lutjanus alexandrei to analyze its characteristics and determine the distinct features. It occurs from the state of Maranhão to the southern coast of the state of Bahia, and its habitats include coral reefs, rocky shores, coastal lagoons with brackish water, mangroves and other...

Liver regeneration may be simpler than previously thought

... are active in a cells ?and software programs that analyze the collected information, the scientists listed all the proteins that help the cells grow and proliferate in both samples. The results were unexpected. The researchers noticed that only a few proteins were common to both processes. Proteins cal...

Lithium builds gray matter in bipolar brains, UCLA study shows

...n and colleagues at UCLA used computer analysis to analyze brain scans collected by collaborators at the University of Pittsburgh in order to determine whether bipolar patients showed changes in brain tissue and, if so, whether those changes were influenced by lithium treatment. Specifically, they employed h...

Nanotechnology meets biology and DNA finds its groove

...le enough to lend itself to large-scale efforts to analyze DNA. "It's a simple technology that works, and that's demonstrated to work for genome analysis," says de Pablo. "It's a very robust method that can be used in a variety of settings." In addition to Schwartz and de Pablo, authors of the PNAS stu...

MIT model helps researchers 'see' brain development

...ematically in a way that allows the researchers to analyze their changes over time and space. The original brain scan is then represented computationally with points. Charting each baby's brain requires about 130,000 points per hemisphere. Yu decomposed these points into a representation using just 42 po...

Female chimps keep the bullies at bay

...oped a new index ?the estrus synchrony index* - to analyze whether female chimpanzees, in the Mahale Mountains National Park in Tanzania, synchronize the fertile period of their reproductive cycles.** The authors identified estrus in females by the size of their anogenital swellings, which is related to i...

Major gene study uncovers secrets of leukemia

...tainable. The St. Jude group used this approach to analyze leukemia samples from 242 pediatric patients with ALL. This identified an unexpectedly high frequency of mutations involving genes that function as master regulators of normal B-cell development and differentiation. A report on this work appears ...
