Infections could contribute to adult brain tumours

... UK each year. These findings suggest a possible link between infection and this type of the disease but by no means provide proof." *The team included UK and Dutch researchers. In the UK, they came from the University of Newcastle upon Tyne and The University of Manchester/Central Manchester and Manch...

A surprising pair of proteins help make healthy eggs

...man granulosa tumors as well as explore a possible link between TAF4b and other forms of ovarian cancer, the fourth leading cause of cancer deaths among women. Ekaterina Voronina, a Brown postdoctoral research fellow, assisted with the research. The Berkeley team included lead author Kenneth Geles, Wei-L...

Nano machine switches between biological and silicon worlds

...d to a high degree of accuracy. These measurements link the biological motor with the electronic signals of the silicon world. The biological element of the device starts with a DNA molecule fixed to the floor of the microfluidic channel. This strand is held upright, like a string held up by a weather b...

Researchers use dirt to stay one step ahead of antibiotic resistance

...yet to emerge clinically for these drugs. "The link between clinical and soil-associated resistance to vancomycin illustrates the value of studying resistance in the soil to rationally anticipate future clinical resistance," said Wright. "It suggests that the soil serves as an under-recognized source ...

Warming trend may contribute to malaria's rise

... current study, the researchers looked only at the link between temperature and mosquito abundance, not at malaria statistics. In future work, Pascual plans to incorporate malaria data and to explore the interaction of various factors that may affect the spread of malaria. "I think it's reasonable to as...

Attention shoppers: Researchers find neurons that encode the value of different goods

...hioppa and Assad's results establish a more direct link between the activity of OFC and the mental valuation process underlying choice behavior. "The activity of these neurons reflects the value subjects assign to the available goods when they make choices," says Padoa-Schioppa. "A concrete possibilit...

Fertility drugs given 'all-clear' in new study

... Tulandi. "Our findings indicate concerns about a link between letrozole and birth defects are unfounded. This is significant because it confirms that letrozole can indeed be used in the treatment of infertility without increasing risk to the fetus." The study contradicts an earlier, much smaller study ...

Lactic acid not athlete's poison, but an energy source - if you know how to use it

...e last puzzle pieces to the lactate story and also link for the first time two metabolic cycles - oxygen-b...m," Brooks said. "This shows us how lactate is the link between oxidative and glycolytic, or anaerobic, metabolism." He and his UC Berkeley colleagues foun...

Utah researchers confirm chromosome may harbor autism gene

...ene, FXR1, appeared to be a likely candidate for a link to autism. FXR1 is similar to the X-chromosome Fragile X gene, FMR1. Mutations in FMR1 cause Fragile X Syndrome, an inherited condition that can cause mental impairments ranging from learning disabilities to severe cognitive problems. Fragile X syndr...

Study finds evolution doesn't always favor bigger animals

...D study is important because it establishes a firm link between climatic change and the body size of organisms, paving the way for a better understanding of the evolution of body size in fossil organisms as well as in environments that are now being impacted by global warming. "There's still a huge deba...

How nerve cells stay in shape

... says. His group thus creates the first conceptual link between molecular processes in the receiving part of the nerve cell and changes in the structure and function of its synapses. This could lead to a better understanding of molecular mechanisms, which lie at the heart of the brain's ability to learn a...

New compound protects against liver cancer

...arly effective in preventing cancers with a strong link to inflammation, such as liver, colon, prostate and gastric cancers. It could also play a role in preventing diseases such as neurodegeneration, asthma and emphysema. The findings are featured in the February 15, 2006, issue of the journal Cancer Res...

How 'hot' emotional brain interferes with 'cool' processing

...s gave us an excellent chance to fill in a missing link in our earlier studies," said Dolcos. "It enabled us to determine whether there was, indeed, a behavioral connection between deactivation of the dorsal system and impaired performance. "The experimental design mimicked the kind of distraction peopl...

Wisconsin scientists find a way to make human collagen in the lab

...esize the human protein because they had no way to link the easily made short snippets of collagen into the long, fibrous molecules necessary to mimic the real thing. But now a team of scientists from the University of Wisconsin-Madison, writing this week (Feb. 13, 2006) in the Proceedings of the Nationa...

Neuroscientists discover new cell type that may help brain maintain memories of smells

...tween sniffs, Blanes cells may provide the missing link needed to answer this critical question. While there are relatively few Blanes cells in the brain, they appear to play a critical role in shaping the output of the olfactory system. The Case researchers found that the influence of Blanes cells o...

MiRNA fingerprint identified in platelet formation

...ncer Genetics Program, was the first to discover a link between miRNA and cancer. In the current study, Croce, who is also a member of the OSU Comprehensive Cancer Center, along with Garzon and colleagues from the M.D. Anderson Cancer Center, examined miRNA activity in the earliest phases of platelet deve...

Single microRNA causes cancer in transgenic mouse

...or author of the study and the first to identify a link between miRNAs and cancer, suspected that a particular miRNA, miR155, was a key culprit in some forms of malignant growth. He and his colleagues have been mapping the activity of dozens of miRNAs in various types of normal and malignant tissues for s...

Researchers unravel DNA tangles and enzyme seamstresses

...owever, the cell would be in serious trouble. "One link could keep the cell from dividing. Two links are even more lethal," says Zechiedrich, who notes that "the results of these computer simulations are very striking." While Chan and his collaborators stress their results represent only a quantitative p...
