Viral DNA sequence a possible trigger for breast cancer

...breast cell transformation, which has largely been attributed to the integration of viral DNA into locations that trigger the expression of host cancer-causing genes. An intriguing wrinkle to this study is the previously reported presence of sequences highly homologous to MMTV Env protein in the DNA of as many ...

NYU Study Reveals How Brain's Immune System Fights Viral Encephalitis

...her cells, which can be replaced. The researchers attributed the spread of viral encephalitis to the inability of lab mice to produce sufficient amounts of interferons to fight the virus. ...

Ice core 'dipstick' indicates West Antarctic ice has thinned less than believed

... the last ice age was beginning to wane, often are attributed in part to melting in West Antarctica. But in a new study led by University of Washington researchers, an ice core of 1,000 meters was used as a sort of dipstick to show that a key section of the West Antarctic Ice Sheet probably never contained as ...

The very unexpected life and death of a leukemic cell

.... The slow rise in the cell count over time can be attributed to the difference between the birth and death rates of the cells, according to the study. The researchers at the Institute for Medical Research at North Shore-LIJ analyzed the kinetics of CLL cells in vivo by employing a non-radioactive labeling tec...

Discovery Promises Simpler Therapy for Sickle Cell Disease

...ymptoms of sickle cell disease have generally been attributed to the physical obstruction of blood vessels by distorted, or "sickled," and rigid red cells, Stamler said. The new findings, for the first time, implicate abnormal vessel dilation by the red cells themselves in oxygen deficiency. That oxygen deficie...

Undesirable expatriates: Preventing the spread of invasive animals

...ury and decreasing thereafter. This decline can be attributed to a reduction in immigration following WWI and increased U.S. regulations on wildlife imports. Conversely, North American introductions to Europe have been on the rise throughout the 20th century as more Americans immigrate to European countries. I...

Norovirus found to cause traveler's diarrhea

... among U.S. travelers to Mexico and Guatemala were attributed to Norovirus, a common cause of nonbacterial gastroenteritis outbreaks usually associated with developed countries, according to a new study by researchers at the Johns Hopkins Bloomberg School of Public Health and other institutions. The researchers...

Ebola virus: from wildlife to dogs

...g 32 % in the villages where human cases have been attributed to an infected-animal source. These domestic animals could therefore become infected and excrete virus over a given period, thus becoming a potential source of infection for humans. This could explain certain as yet un-elucidated human infections. It...

Big differences in duplicated DNA distinguish chimp and human genomes

... genome landscape between chimps and humans can be attributed to large segmental duplications. Such large-scale genetic events have altered more total base pairs - about 2.7 percent of the genome - than differences from single base-pair changes, which account for about 1.2 percent of the genome. "For all the ...

Pregnant women at higher risk for HIV, Uganda study finds

Lands surface change on Alaska tundra creating longer, warmer summers in Arctic

...ummer temperatures in northern Alaska could not be attributed to regional atmospheric circulation patterns or to a reduction in sea ice in the summer or to an increase in cloud cover. The observed summer temperature increases are likely related to a global warming trend that has led to a longer snow-free season...

Naturally occurring asbestos linked to lung cancer

...d Health statistics. About 3,000 deaths a year are attributed to exposure to secondhand tobacco smoke, according to U.S. Environmental Protection Agency statistics. Ultramafic rock is distributed throughout the Sierra Nevada, Coast Ranges and Klamath Mountains in Northern and Central California, and has been a...

Huntington's cure in flies lays groundwork for broader treatment approaches

...s, Yin says, particularly for diseases that can be attributed to dozens and even hundreds of abnormal gene functions. Yet in some cases, it might turn out that gene pathways stemming from different genes converge at some point, into one common "superhighway," says Yin. "If you know that, you can do something i...

New processing method reduces peanut allergenicity

...e most significant rise in food allergies has been attributed to peanuts and other nuts. The allergenicity of peanuts is due to the presence of specific types of proteins including Ara h1 and Ara h2. Yu and her colleagues discovered during a study of various processing methods on the allergenicity of peanuts th...

Toxic flood lifts lid on common urban pollution problem

... other major failures in the city's infrastructure attributed to Hurricane Katrina. Though these are certainly real problems, it's also highly likely that the stagnant waters are contaminated because they've soaked up "legacy" pollutants that accumulated during normal conditions on the city's streets, sidewalks...

Ancient anthropoid origins discovered in Africa

...37 million years ago in Africa was a single tooth, attributed to a species called Biretia piveteaui. What's more, the latest discoveries of the two species suggest that a 57-million-year-old African primate called Altiatlasius from Morocco might even be the earliest anthropoid ancestor. ...

Viagra's hidden help for wildlife

...cies used in TCM impotence treatments. The pair attributed some of this decline to Viagra, despite scepticism among many academics and wildlife experts. In 2002, the global market for TCM products and treatments was valued at more than $20 billion, according to the Chinese firm Shenzhen Matrix Information ...

New evidence supports century-old theory of cancer spread

...lls exhibit a remarkable number of traits normally attributed to white blood cells known as macrophages, including the ability to migrate to lymph nodes and distant organs and to form a new blood supply. Our data indicate that they do this by hybridizing with macrophages," said lead author John Pawelek, researc...
