Unraveling a stomach cancer puzzle

...t these basic research findings may one day impact directly on the treatment of stomach and other cancers. "We've demonstrated that by lowering Stat3 hyperactivity we can suppress stomach cancer formation, importantly without affecting Stat3's other important roles in the body. Add to that the evidence sugges...

Wild grasses and man-made wheats advance research capabilities

...untapped genetics," Rudd said. "They can be tapped directly through laboratory crosses, but it is difficult." ...ild, we may make a synthetic hexaploid from it, or directly cross into wheat," Rudd said. "Through traditional genetic variability we've been able to gain 1 pe...

Assessing the Amazon River's sensitivity to deforestation

...nderstanding of how human decisions about land use directly impact the River and its ecosystems, which can help people make more informed decisions for the future of Amazonia," he adds. ...

Could better mangrove habitats have spared lives in the 2004 tsunami?

... heavily burned into the memories of those who are directly involved. In the aftermath of the disaster, academics and politicians alike are trying to investigate how the number of casualties could have been reduced and, more important, how such severe damage can be avoided if a tsunami ever strikes again. In ...

Missing Receptor Molecule Causes Tumor Growth

...firmed by testing 36 different tumor tissues taken directly from patients. In comparison, these cells represent the real causes of disease much better than cell cultures commonly used for experimental research. It was determined that in 20% of the tissues examined the gene responsible for DR4 was methylated t...

Nicotine triggers the same brain reward circuitry as opiates

...reward. However, unlike opiates, nicotine does not directly activate the brain's opiate receptors, but activates the natural opioid reward pathway in the brain. The researchers, led by Julie Blendy of the Transdisciplinary Tobacco Use Research Center (TTURC) at the University of Pennsylvania, said their find...

New Scripps Oceanography project to study sediments and ecosystem restoration in Venice lagoon

... coastal wetland that surrounds the city and links directly with the Adriatic Sea through inlets. A team of scientists with SIOSED (Scripps Institution of Oceanography SEDiment research group) will dissect and analyze key elements of Venice Lagoon's sediment through a program integrating geochemical, physica...

Tagging pathogens with synthetic DNA 'barcodes'

...ble to the naked eye. Or the color can be observed directly through a fluorescent light microscope, which is useful in situations where the geographic distribution of the target molecules is important, Luo said. For convenience, a computer can convert the subtle differences in light intensity between, say 4G...

A novel method to measure circadian cycles

...rences in circadian rhythms; it does not, however, directly measure the signal from the central coordinator of circadian rhythms in the brain, the suprachiasmatic nucleus. In the future, scientists may use the new method to screen large populations for genetically linked sleep disturbances such as advanced...

Physical and functional interaction of key cell growth molecules linked to cancer

...studies suggest that EGFR itself probably does not directly regulate gene expression, but may interact with ot...AT3 is a molecule that is known to bind to DNA and directly regulate gene expression. STAT3 has also been shown to have a major role in oncogenesis. Importantly...

Envisat and ERS-2 reveal hidden side of Hurricane Rita

...adar was able to pierce through swirling clouds to directly show how the storm churns the sea surface. This image has then been used to derive Rita's wind field speeds. Envisat acquired this Advanced Synthetic Aperture Radar (ASAR) image at 0344 UTC on 22 September (2345 on 21 September in US Eastern Dayligh...

Researchers identify genes associated with lung transplant rejection

... could lead to the development of medications that directly target genes responsible for the scarring process in the lung, instead of anti-rejection drugs that broadly compromise the immune system, which are the major tools currently available to fight lung rejection. Co-authors of the study were Xiang Xu, M...

Naturally occurring asbestos linked to lung cancer

... the risk of developing malignant mesothelioma was directly related to residential proximity to a source of ultramafic rock. Specifically, the odds of having mesothelioma fell by 6.3 percent for every 10 kilometers (about 6.2 miles) farther a person lived from the nearest asbestos source. The association was ...

Once given 'no respect,' cells' tiny RNAS take driver's seat

...e experiments and others, they discovered that Myc directly controls the gene for a set of six microRNAs in a region of chromosome 13 that is already tied to development of human lymphoma. MicroRNAs are made by the same cellular machinery that makes other forms of RNA -- like the messenger RNA used to build ...

Aloe vera coating may prolong freshness, safety of fruits and vegetables

...ffects of Aloe gel on human consumption were not directly measured in this study, the coating is believed to be safe, the researchers say. They note that Aloe vera gel has been used as a functional ingredient in some foods and beverages for years. In addition to preserving table grapes, which are highly p...
