High fiber intake reduces estrogen levels in Latina women, according to researchers

...ltiethnic Cohort Study of Diet and Cancer to begin looking at the relationship between dietary fiber and estrogen levels in Mexican-American women, an ethnic group in which dietary fiber intake is higher on average than in most other populations. Even then, says Monroe, she selected for the study those who h...

Gene linked to greater risk of heart disease in type 2 diabetes

...ogether like beads on a spiral necklace. They were looking for variants in this sequence that are associated with increased risk of heart disease. Studying 585 people who did not have diabetes, the researchers found five different CD36 variations that were associated with increased levels of free fatty acids...

Mice thrive despite massive genetic makeover

...ntially disposable? "In these studies, we were looking particularly for sequences that might not be essential," said Eddy Rubin, Director of the JGI, where the work was conducted. "Nonetheless we were surprised, given the magnitude of the information being deleted from the genome, by the complete lack o...

Neurosurgeons looking at stem cells from skin to fight brain tumors

...team of neurosurgeons and scientists from Italy is looking into whether stem cells derived from a brain tumor patient's own skin can be used to fight the tumors. The researchers successfully grew stem cells from skin samples of adult patients with brain tumors. It is hoped that these cells can then be used...

Pesticides may promote Parkinson's disease and exercise may offer protection

...g news for people with Parkinson's disease who are looking for safe and effective ways to stem the progression of the illness. In past studies, the researchers reported that rats forced to use limbs that mimicked the effects of Parkinson's could regain motor skills within a week of physical activity. When s...

Sandbagging cancer in the bloodstream

...ity where it is released. This is easily seen when looking at the blood supply to tumors under the microscope, says Cheresh. "Anywhere there is VEGF, there is a vascular permeability," he says. "Tumors have blood vessels that are very leaky." Once in the circulation, tumor cells can travel to distant parts o...

Study at Joslin shows ease of introducing technology to kids with diabetes

...se levels improves diabetes control, so we've been looking for approaches that encourage patients and their families to monitor their blood glucose levels," Dr. Laffel said. Improving diabetes control helps to prevent complications, such as blindness, stroke, and kidney disease, which are associated with pro...

Genetically endowed worm may substitute for rodents in some toxicology testing

...in fact replace the rodent. But for now what we're looking for is something that helps us set priorities on what to test in rodents." As his multimillion dollar contract begins, Freedman has seen his Nicholas School lab triple in size to more than 15 people. Along with the new hires have come...

'Broken' gene reveals evolution of salt retention and possible ties to hypertension

...evolutionary biologists took a different approach, looking at the genetics of salt processing. They focused on a gene called CYP3A5, part of a family known as cytochrome P450 genes, which help the body break down and eliminate a wide range of compounds, including many drugs and salt. In the kidney, CYP3A5 ...

Actin muscles in on DNA transcription

...ring, stitching together the RNA message. "We were looking for a motor, but we found something completely different," de Lanerolle said. He suspects that actin does act as a motor once RNA polymerase II begins transcription, but that has yet to be proved. "Learning about the precise components and sequence o...

Are museum collections of ancient life representative?

... of plants and bugs. Increasingly, researchers are looking to museum collections to answer questions about what lived on earth millions of years ago and how life evolved. Digging up stream beds, river banks, flood plains, and road cuts and analyzing the resulting boxes of dirt and rock is time consuming and ...

Who laid the first egg?

... as if they can unwind to a tube structure. We are looking for more evidence, but if that is true, it might link the embryo fossils to the tubular coral-like animal." The researchers will slice open a hatched embryo specimen that appears to be unwinding to see if it has cross-walls. "That would indicate it i...

Researchers tracking sources of arsenic contamination in water

... Tech researchers from geosciences and biology are looking at where arsenic occurs in water, how it is gettin...d through human activity (mining). But we are also looking at how the mineral weathers; then, once it is in the water, how it interacts with the sediment and w...

Researchers unlock mysteries of toxic metals in the largest contaminated site in United States

...With that magnification, you can find what you are looking for," Hochella said. Hochella, Munster professor Andrew Putnis, and Japanese post-doc Takeshi Kasama looked at samples and found important minerals three to 200 nanometers in size. "We found what we think is a new mineral, a manganese oxide hydrate t...

First human trial of bioartificial kidney shows promise for acute renal failure

...stage chronic renal failure. Investigators are not looking for volunteers for that trial, and the device is not ready to be implanted in patients. In addition to Humes, U-M study authors were William Weitzel, M.D., assistant professor of Nephrology; Robert Bartlett, M.D., professor of Surgery; and Fresca Swa...

Structure of new DNA enzyme family member found

The protein is AIRs kinase, and to the researchers' surprise, its shape is similar to other members of the ribosi...

UNC Lineberger researchers identify molecular markers of aging

...nd ARF. "At the very least, our work suggests that looking at the expression of one or both proteins will make a great biomarker of aging - a tool to clinically determine the actual molecular age of people, as opposed to just their chronological age," said Lineberger member Dr. Norman Sharpless, the senior a...
