US life expectancy about to decline, researchers say

...y in younger generations, the authors were able to illustrate that in the coming decades the risk of death from obesity-related causes is about to rise. The hardest hit will be minorities, because of limited access to health care and because they have experienced the most rapid increases in obesity in recent ye...

Molecular models advance the fight against malaria

... able to apply computerized modeling techniques to illustrate exactly how the drug interacted with the cytochrome bc1 complex ?the respiratory enzyme the parasites need to live and multiply -- on a molecular level. With this new understanding of how the parasites were able to counter the effects of atovaquone, ...

No relief for Pacific Northwest drought

... drought and fire risk conditions are available to illustrate this story, at the web site of OSU News and Communication Services, at http://oregonstate.edu/dept/ncs/photos/index.html ...

NSAID drug protects against intestinal tumors in mice, despite poor diet and gene losses

...levance for preventing human colon cancer, they do illustrate the interplay between genes and common nutritional and medicinal agents in development of cancer in the intestines. The drug they tested, sulindac, was a highly effective chemoprevention agent, the researchers say, because it worked to induce expres...

Gov't Creates Gene Database of Normal Human Tissues

...organs that share a common way of functioning. To illustrate the kind of useful data that can emerge from using this tool, Khan's team analyzed 100 samples of the most common pediatric solid tumor cancer, neuroblastoma (NB), which accounts for 7 percent to 10 percent of all childhood cancers. Even though the t...

Bugs, even 'bad' ones, can be educationally beneficial, new book says

... conversations with his entomologist colleagues to illustrate what we can learn from bad bugs. Many of the pests he describes are found in Illinois, including the corn rootworm. Other regional insects also are mentioned, such as the evergreen bagworm that spans the east coast of the United States and stretches...

Vitamin A's paradoxical role in influencing symmetry during embryonic development revealed

...s. The novel findings reported by Belmonte's team illustrate how the development of the antero-posterior and left-right axes is coordinated by vitamin A. Retinoic acid exerts its influence at the stage when the embryonic stem cells enter the node region of the embryo and begin forming the embryo's three main l...

Stem cell treatment improves mobility after spinal cord injury

...portance of myelin loss in spinal cord injury, and illustrate one approach to treating myelin loss. Keirstead and his colleagues are currently working on other approaches using human embryonic stem cells to treat chronic injuries and other disorders of the central nervous system. In previous studies, Keirstead...

Understanding biases in epidemic models important when making public health predictions

...d and data from an influenza outbreak were used to illustrate the potential bias in model predictions. The impact of such differences on predicting the spread of new, highly transmissible diseases could be important to public health workers, said Wearing. Underestimating the transmissibility of an infection co...

Inhaling large amounts of salt can cause hypertension

...d and data from an influenza outbreak were used to illustrate the potential bias in model predictions. The impact of such differences on predicting the spread of new, highly transmissible diseases could be important to public health workers, said Wearing. Underestimating the transmissibility of an infection co...

Field of beams - Novel system uses polarized light pulses to reveal crop health

...d and data from an influenza outbreak were used to illustrate the potential bias in model predictions. The impact of such differences on predicting the spread of new, highly transmissible diseases could be important to public health workers, said Wearing. Underestimating the transmissibility of an infection co...

Sensor web simulation investigates technique to improve prediction of pollution across the globe

... accuracy of the forecast. Talabac's team hopes to illustrate how such a model-driven sensor web could be used to enhance current measurement techniques, and bring to bear multiple complementary instruments to respond to rapidly changing environmental conditions. "These simulations fall into the category of 'p...

The shape of things to come: Morphology database going global

... journals often do not publish all the images that illustrate an article, researchers now must go to a museum or depository to view the specimens or arrange for a loan. Ronquist envisions a system in which authors would deposit images into MorphBank, and journals could point readers to the database to view them...

Genetic testing still smart choice, despite uncertainties

...g data from UF's IVF program and other programs to illustrate the different paths an embryo takes as it develops. While half of embryos turn out normal, with no mosaicism, the other half produce irregular cells as they divide. Embryos that become mosaic after their cells divide twice typically stop progressin...

Aggression-related gene weakens brain's impulse control circuits

...the week of March 20, 2006. "These new findings illustrate the breathtaking power of 'imaging genomics' to study the brain's workings in a way that helps us to understand the circuitry underlying diversity in human temperament," said NIH Director Elias A. Zerhouni, M.D., who conducted MRI studies earlier in ...

Nano-particles effective in killing cancer with one-two punch of chemotherapeutics

...ed online in the journal Molecular Pharamaceutics, illustrate the broad clinical potential of polymersomes. "The system provides a number of advantages over other Trojan horse-style drug delivery system, and should prove a useful tool in fighting a number of diseases," said Dennis Discher, a professor in Pe...

Parkinson's disease mechanism discovered

...d. Bonini added that the research team's findings illustrate the power of animal models in revealing insight into Parkinson's disease. "These results highlight the value and importance of very simple model organisms in studying these disorders," she said. "For example, yeast is only a single cell, not even a n...

New treatment for food poisoning

...tics. Professor Vazquez-Boland said: "Our results illustrate that antibiotic resistance in the laboratory does not always mean that the drug will not work in the infected patient. This work brings some optimism to the highly worrying problem of the increasing resistance to antibiotics." The Listeria bacteria ...

Where we change our mind

...rucial in complex real-world environments. We also illustrate the utility of statistical model-based inference and regression in delineating key task parameters that may be represented in spatially distinct brain regions," they concluded. ...

Five new technologies that promise to transform medicine

...panels attached to the retinas. These scenarios illustrate potential clinical applications of technologies currently under development, says Professor Combs. For instance, devices that can sense and transmit heart and breathing rates already exist and implantable lenses are well-known. Other emerging tech...
