Mass. General study finds potential ovarian cancer stem cells

...tudy co-author. "We feel that non-traditional, possibly innovative approaches will be required to eradicate these stem-like cancer cells and ultimately cure ovarian cancer. With its potential to maintain the ability to inhibit the proliferation of these cells, MIS may play a role in these new therapeutic...

Computational model simulates AZT metabolism in mitochondria

...ople. There are many different ways that AZT could possibly interfere with mitochondria to cause the toxic side-effects. Our job is to model these proposed toxicity mechanisms to see which ones could actually lead to the mitochondrial defects found in AIDS patients." He added: "It is possible that no single ...

Bones hold the key to blood renewal

...niches do they morph into specialized blood cells, possibly becoming immune cells for fighting infection or cells for blood clotting and healing after injury. They can even respond to calls for help from organs such as the liver, migrating through the bloodstream to assist in repairing damage. The inner wa...

Genes discovered that allow gum disease bacterium to invade arteries

Insect predation sheds light on food web recovery after the dinosaur extinction

...t climate and without insect predatory pressure -- possibly because their rainforest-type leaves were already thick, tough, and hard to eat -- plant species proliferated and thrived for a short time. At Mexican Hat, 16 species of mostly thin-leaved, poorly defended, typical Paleocene plants temporarily became...

Food-crop yields in future greenhouse-gas conditions lower than expected

...or C3 crops, such as rice, wheat and soybeans, and possibly little or no stimulation for C4 crops that include maize and sorghum," said Stephen P. Long, a U. of I. plant biologist and crop scientist. FACE technology, such as the SoyFACE project at Illinois, allows researchers to grow crops in open-air fields...

Key stress protein linked to toxicities responsible for Parkinson's, Alzheimer's

...ic defects as well as exposure to free radicals or possibly other types of cellular stress can cause small structural defects that lead to protein misfolding. If the misfolded proteins cannot be refolded properly or degraded, they may build up in the cell to cause dysfunction. Defects in either the protein ...

Key to early diagnosis of autism may be in the placenta

...acenta what may be the earliest marker for autism, possibly helping physicians diagnose the condition at birth, rather than the standard age of two or older. The findings are reported in the June 26 online issue of Biological Psychiatry. Autism is a developmental disorder that has a profound effect on socia...

Mitochondrial DNA sequencing tool updated

...Included in this tally were several mutations that possibly are informative of the disease. "The real interesting thing is nobody has been able to study these D-loop alterations very well," said Califano "They clearly occur in tumor cells, and there is some type of selection process for them. But ...

Marine 'dead zone' off Oregon is spreading

...s continue to blow, we expect to see continued and possibly significant die-offs." As events such as this become more regular, researchers say, they appear less like an anomaly and more like a fundamental shift in marine conditions and ocean behavior. In particular, a change in intensity and timing of coast...

Stanford snake venom study shows that certain cells may eliminate poison

... chills, with numbness, nausea, blurred vision and possibly convulsions before it's all over. Such misery is produced by a veritable witches' brew of toxins in snake venom. It's long been thought that the body's own immune system, rather than reducing the symptoms, may make things worse. But now researchers...

Oxidation defense in mosquitoes benefits malaria parasite

...xykynurenine (3-HK) accumulation in mosquitoes and possibly other species as well. "3-HK is oxidized easily under physiological condition, stimulating the production of reactive oxygen species, which can damage cells," said Li. Mammals have various biochemical pathways of disposing of 3-HK, which mosquitoes...

New crop of technology reveals plant health

...her, by initially developing a prototype, and then possibly commercialising the system," says Tooke. "That work will go beyond the life of this project, however. PLANTS ended in March 2006." However, none of those system improvements will make the plants totally stress free, but if the project's crop manage...

Nanopore method could revolutionize genome sequencing

...hat are tens of thousands of base pairs in length, possibly as long as an entire gene, in one pass through the nanopore. With the Sanger method it is necessary to chop the DNA into smaller pieces, copy the DNA and use multiple sequencing machines, which introduces additional sources of error." The study w...

Radiotherapy advance points way to noninvasive brain cancer treatment

...might some day lead to less invasive treatment and possibly a cure of this disease. "It's the most lethal can...Stasio says the next steps will include animal and possibly human clinical trials. "If we do see that we can cure animals from their cancers, then it's worth ...

Plants used to detect gas leaks, from outer space!

...hich is the current method, and would be safer and possibly cheaper." Steven will present his research on Thursday 6th April at the Society for Experimental Biology's Annual Main Meeting in Canterbury [session P3] In the UK in 2001, emission of methane from the gas distribution system was 16% of the total...

Stem cell transplants improve recovery in animal models for stroke, cerebral palsy

...herapy, along with aggressive physical therapy and possibly tPA can work synergistically to reduce that disability. "These are not going to be cures, but this level of recovery is significant, and could help get somebody out of a bed and into a wheelchair or out of a wheelchair to walking with a cane or from...

History of human cannibalism eats away at researchers

...uding positive selection, purifying selection, and possibly even short periods of balancing selection." On a more technical note, the study cautions researchers involved in SNP-based population genetics studies. The work is one of the first to empirically demonstrate how SNP ascertainment can introduce a s...

ASU researchers find link between social behavior, maternal traits in bees

"One theory is that social behavior emerged through new evolutionary inventions. Another is that ancestral solitary phenotypes (characteristics o...
