Genes discovered that allow gum disease bacterium to invade arteries

...ow them to invade and infect human arterial cells, offering one possible explanation for a perceived connection between gum disease and heart disease. Scientists from the University of Florida, Gainesville, present their findings today at the 106th General Meeting of the American Society for Microbiology in ...

Alaska seal pup diet may hold key to decline of population

...that are nutritionally stressed may not reproduce, offering clues to why some harbor seal populations are falling, Polasek said. Next steps The seals will continue their low fat and high fat diets as the longitudinal research continues. "We're curious to find if it will take longer for the low fat diet a...

One fish, two fish: New MIT sensor improves fish counts

...e studied. The images can be updated every minute, offering a chance to continuously monitor the shoals as they change in size and shape over time. The new technology works best along the continental shelf, so the researchers focused their attention on the waters south of Long Island, New York. When they fir...

Molecular mechanism may explain how fevers spark seizures

...functional defects of the mutant GABA-A receptors, offering insight into the mechanisms underlying those epilepsies. One of the common features in the families with mutations in the GABA-A receptor gamma subunit -- one of several protein "parts" that come together to make a functional receptor -- is a histo...

UC Riverside psychologist explores human perception, finds 'wow factor'

Report finds cruise industry is protecting the precious places it visits

... destinations throughout the Caribbean and Hawaii, offering a non-invasive way to explore marine ecosystems. "Although cruise tourism has the potential to overwhelm fragile destinations if not managed effectively, the industry is also a great potential ally for conservation, because many cruise passengers a...

Salmonella caught red-handed

...for this is redundant enzymes, as well as the host offering a wide range of nutrients, which means Salmonella does not depend on its own biosynthetic abilities. Only a few enzymes in certain metabolic pathways are really necessarily to keep Salmonella bacteria alive. Most of these essential enzymes are miss...

New nano-canary in the nanotoxicology coalmine: The body itself

...ctra are captured in minutes in live cell studies, offering a tool to rapidly detect whether nanoparticles are biologically active. This information can be used to prioritize nanoparticles for further study to ascertain the nature of the biological activity in terms of toxicity. A broader approach underway...

Free HIV tests cheaper than charging when goal is preventing AIDS

...t," Thielman said. The KIWAKKUKI program started offering HIV tests and counseling in March 2003 for just about a dollar ?the median income in Tanzania is around $564. The HIV infection rate in Tanzania is about 8.8 percent, though about 16.7 percent of those tested at KIWAKKUKI are HIV positive, Thielman s...

Technique offers new view of dynamic biological landscape

... organisms, ultimately to humans. In addition to offering important basic insights into the roles of proteins and genes, E-MAPs will also contribute to understanding evolutionary processes. "In evolutionary theory, the structure of epistatic gene interactions is critical," he said. "To understand how differ...

Cancer support cells may evolve, fuel tumor growth, study shows

...ay's (Dec. 16) issue of the journal Cell.While not offering immediate application to the treatment of human cancers, the research indicates that new anti-tumor therapies may be more effective if their targets are broadened to include molecules within supporting cells of the cancer.These additional target cell...

Scientists learn to predict protein-stabilizing ability of small molecules

... a handful of facilities across the country offering this minimally invasive, high-tech treatment. David I. Lee, M.D., a national expert in robotic surgery, was recruited to Penn and named Chief of the Division of Urology at Penn Presbyterian Medical Center, where the robotic prostate program is based....

Penn Surgeons Use Completely Robotic Surgery to Successfully Treat Prostate Cancer

Cartilage is the dense connective tissue usually found between bones to allow the smooth movement of joints. Research to be published in Tissue Engineering shows ...

Nanoparticles, nanoshells, nanotubes: How tiny specks may provide powerful tools against cancer

... monoclonal antibodies, is detecting cancer cells, offering a potential cost-effective way to diagnose whether cells are cancerous or not in a matter of minutes versus hour or days with current methods. Nanoshells, filled with gold particles, are destroying tumor cells when heated with laser light. What's m...

Center releases new public survey on stem cells

...develop into virtually any other cell of the body, offering a hypothetical tool kit for repairing diseased hearts, mending broken spinal cords, or correcting genetic diseases, among other hoped-for benefits. Stem cells derived from very early embryos show the most promise in research to date, but the embryo ...

New vaccine platform may fight infections with causes from influenza to bioterrorism

... approach is worth investigating its potential for offering protection against weaponized agents, such as anthrax. In mice depleted of CD4+ T cells, which are essential for signaling other cells and for producing antigen-specific antibodies, the vaccine strategy provided protection against pneumocystis. Impo...

DNA size a crucial factor in genetic mutations, study finds

...,'' Kool says. The researchers investigated it by offering bases of different sizes to the DNA polymerase I enzyme and measuring how accurately the enzyme made new DNA copies. About once every 10,000 to 100,000 times the enzyme will put in the wrong base, choosing for instance a G instead of a T to pair with...
