Genes and biomarkers that allow doctors to choose the right therapy for the right patient

...erimental agents." Gray and his colleagues have developed a system to evaluate drug response comprised of a panel of 50 breast cancer cell lines. Each of these cell lines represents a single variant among the different genomic abnormalities found among breast cancers. They measured molecular profiles of ea...

No carrier necessary: This drug delivers itself

...iophotonics and Roswell Park Cancer Institute have developed an innovative solution in which the delivery system is the drug itself. They describe for the first time in Molecular Pharmaceutics a drug delivery system that consists of nanocrystals of a hydrophobic drug. The system involves the use of nanocr...

Cancer tip -- Nanoparticles can damage DNA, increase cancer risk

...cerned because so many new nanoparticles are being developed and there is little regulation on their manufacture, use and disposal." Pacheco and her colleagues looked at how two different types of nanoparticles could cause DNA damage in the MCF-7 line of breast cancer cells. She and her team examined t...

The desert is dying

...nous resource management, which desert people have developed through millennia, is changing. Desertification has been recurrently discussed and questioned since the 1970s. The focus has been on desert borderlands, while changes in sparse but important vegetation resources within the desert core have been neg...

Bats prey on nocturnally migrating songbirds

... stable isotopes was applied because this recently developed method allows tracking species' main dietary specializations and trophic level position along food chains. The researchers concentrated on carbon and nitrogen isotopes, which are among the best dietary tracers. They analysed their concentrations in b...

Natural gut hormone offers hope for new obesity drug

...eding Drug Discovery initiative. The drug is being developed by one of the world's leading obesity experts, Professor Steve Bloom at Imperial College London's Hammersmith Hospital campus. "Over 30,000 deaths a year are caused by obesity in England alone, so there is a clear need to develop a treatment to tac...

Racing neurons control whether we stop or go

...s laboratory to show how a theoretical model Logan developed more than 20 years ago is implemented by the brain. "I developed the race model to explain behavior on a task called the stop signal task with a friend of mine, Will...

New antibacterials being developed to tackle MRSA superbug

...ial medicine that kills the superbug MRSA is being developed under a new scheme launched by the Wellcome Trust....es and the wider community." The compounds being developed by Prolysis under the award from the Wellcome Trust block the ability of the MRSA bacteria to divide...

Out of Africa -- Bacteria, as well

.... The researchers also discovered that differences developed in the genetic makeup of the bacteria populations, just as it did in that of the various peoples of the world. This has also given scientists new insight into the paths taken by man as he journeyed across the Earth (Nature online, February 7, 2007). ...

New research shows that flu is a trigger of heart attacks

...djid said that a number of new vaccines were being developed against avian flu virus (the most likely cause of the next flu pandemic), "In addition, we are rapidly stockpiling antiviral drugs (such as Tamiflu), so I think we are likely to have the means of preventing or combating the virus, if nature doesn’t t...

Procedure predicts embryos most likely to result in pregnancy

...Yale School of Medicine and McGill University have developed a procedure that estimates the reproductive potential of individual embryos, possibly leading to a decrease in multiple-infant births and a higher success rate in women undergoing IVF. Over 100,000 in-vitro fertilization procedures are performed eac...

Trojan horse strategy defeats drug-resistant bacteria

...idea of using gallium as a substitute for iron was developed by a group led by Bradley Britigan, a researcher at the University of Cincinnati and a co-author on this study. The general approach of targeting stresses already applied by natural defense mechanisms could be a promising new way to treat infections....

Are journal rankings distorting science?

...citations to papers in scientific journals. It was developed as a simple measure of quality and has become a proxy for the importance of a journal to its field. But a report by the BMJ this week warns that the popularity of this ranking is distorting the fundamental character of journals, forcing them to fo...

Map predicting spread of avian flu

...erlands is the only recent epidemic of HPAI in the developed world. Gert-Jan Boender and colleagues have examined the data from this outbreak and produced a model which can predict the probability of infection from one farm to another; the 'transmission kernel'. They also identify high-risk areas in the Nether...

Cheaper, better disease treatments expected from faster approach to developing antibodies

...hting antibodies entirely within bacteria has been developed by a research group at The University of Texas at Austin. The group led by Dr. George Georgiou developed the new antibody-production approach to improve upon processes used previously to identify new drugs...

QUT scientists on the way to sifting out a cure for HIV

...ity of Technology scientists. QUT scientists have developed specially designed ceramic membranes for nanofiltration, which are so advanced they have the potential to remove viruses from water, air and blood. Associate Professor Huaiyong Zhu, from QUT's School of Physical and Chemical Sciences, is leading t...

Einstein's tea leaves inspire new blood separation technique

Scientists at Monash University in Australia have developed a process for rapidly and efficiently separating blood plasma at the microscopic level without any moving parts, potentially allowing doctors to do blood tests without sending samples to a laboratory. The new method uses the same principle that cause...

Gene expression test reveals ER and HER-2 status of breast tumors

...er reports in Lancet Oncology online. Researchers developed and validated a new genomic microarray test that identifies whether a tumor's growth is fueled by the female hormone estrogen and the role of a growth factor receptor known as HER-2 that makes a tumor vulnerable to a specific drug. The status of thes...

Scientists map key landmarks in human genome

Dana-Farber Cancer Institute researchers have developed a powerful method for charting the positions of key gene-regulating molecules called nucleosomes throughout the human genome. The mapping tool could help uncover important clues for understanding and diagnosing cancer and other diseases, the scientis...

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

... Institute of Technology and Emory University have developed an easier and faster method to detect these types ...us, micron-sized, silica beads. The researchers developed a technique to simultaneously or sequentially add optical and magnetic nanoparticles into the beads....
