Cancer-killing invention also harvests stem cells

... secondary tumor. This is how cancer spreads. He put these facts together with one more, very important fact: the selectins grab onto a specific carbohydrate on the surfaces of white blood cells, stem cells, and cancer cells. Associate Professor King decided to capture stem and cancer cells before th...

New sucker-footed bat discovered in Madagascar

...ld biologist and lead author of the study. "We can put conservation efforts on behalf of this bat on the backburner because it is able to live in areas that have been completely degraded, contrary to what is indicated or inferred in the current literature." This underlines the importance of basic scien...

Blame the brain for high blood pressure

...rain, and not the heart or blood vessels, has been put forward by scientists at the University of Bristol, UK, and is published this week in the journal Hypertension. Dr. Hidefumi Waki, working in a research group led by Professor Julian Paton, has found a novel role for the protein, JAM-1 (junctional a...

Infection detectives use disease 'fingerprints' to track common infections in children

...us and can go home, and who has to be admitted and put into the intensive care unit and treated with antibiotics. That’s our goal," said Dr. Ramilo. "This is just the first step. But it establishes a basis for us to do that." While pediatricians couldn’t perform the analysis in their offices, research...

Wheat can fatally starve insect predators

...ing these different wheat genes, we're starting to put together a bigger picture of how Hessian fly-wheat interactions trigger resistance in the plant," Williams said. "We think that some of this has to do with the plant producing enough lectin that it just becomes so unpalatable that the insects can't f...

New findings blow a decade of assumptions out of the water

...ite of a lot of nitrogen fixation, that would have put the two processes half a world away from each other. Scientists had estimated that, at those distances, it could take 1,000 years to re-balance the ocean's nitrogen cycle if large-scale changes were to occur in either nitrogen fixation or denitrifica...

Elucidation of the genome for diabetics with DNA chips

... These individuals become hyperglycaemic when they put on weight and are resistant to the insulin they produce. The team of Philippe Froguel was the first to identify a gene associated with DT2 ?that encoding glucokinase ?in 1992. Several other such genes have since been discovered, but together these ge...

FSU researchers determine a critical factor in workings of proteins

...re paper, Zhou and graduate student Razmi Alsallaq put forth a new theory that has been proven to accurately predict the association rate for proteins by developing a theoretical model for the association process. A central component of the model is the transition state, a phase that two associating prot...

Twin studies reveal genetic components leading to cardiac and kidney disease

...studying many traits and genes, we have started to put together unexpected stories," he said. Studying genetic variations in twins provides scientists with data on traits that are heritable, or passed down through human DNA, versus those determined by the environment, age or how a person cares for his...

OHSU lab finds meth receptor that could lead to therapy

...omposed of six receptor genes in humans. "When you put it all together, what you realize is that meth acts on several signaling systems and that a successful therapeutic treatment will likely require modulation of several targets simultaneously. We still have a lot to learn about how meth affects the bod...

Notorious cancer gene may work by destroying messenger

... PMR1 to halt production of proteins that normally put the brakes on cell growth ?tumor-suppressor proteins, for example, or other growth-regulating proteins.? In healthy cells, Src helps control cell proliferation, differentiation, survival and movement. Mutated Src is found in about half of all colo...

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

...ar to bar-coding -- once you barcode the beads and put them in the urine or blood sample, you can remove them and decode what proteins or viruses have attached to individual beads based on their spectral signature," explained Sathe. The process of creating these beads is quite simple, according to Sat...

Computer scientists join in search for ivory-billed woodpecker

...eras are housed in weatherproof cases. "If you put a normal computer out there, it wouldn't function very long because of the humidity and the rain," Song said. The hard disks are removed routinely from the computer by birdwatcher M. David Luneau, associate professor in the University of Arkansas...

Rewarding fat rats

...arried out by Shizgal's team, chubby lab rats were put on a diet to reduce their fat mass and, hence, their leptin levels. They found that restricting the rats' diet to one meal per day not only made them lose weight, but also made reward sensations stronger. Conversely, increasing the level of leptin in...

Napoleon's mysterious death unmasked, UT Southwestern researcher says

... Napoleon Bonaparte's cause of death might finally put to rest nearly 200 years of lingering mysteries about the illness that killed the French emperor during his island exile, a UT Southwestern Medical Center scientist reports. American, Swiss and Canadian researchers applied modern pathological and t...

Researchers discover genetic cause for word-finding disease

...ho do very complicated things even when they can't put two sentences together," Mesulam said. Alzheimer's patients lose interest in their hobbies, family life and just sit doing nothing, he noted. As PPA progresses over 10 to 15 years, however, patients eventually lose their ability to function indepen...

Stopping plants from getting sick

...e hard work my trainees and students and post-docs put in as they worked with me during their careers," says Kronstad, a biologist at the University of British Columbia. "There are about 40 other people who I wish could share this fellowship with me." Kronstad's NSERC-funded research focuses on the sm...

The origin of the brain lies in a worm

...rovide strong evidence for a theory that was first put forward by zoologist Anton Dohrn in 1875. It states that vertebrate and annelid CNS are of common descent and vertebrates have turned themselves upside down throughout the course of evolution. "This explains perfectly why we find the same centralis...
