Cancer researchers at Jefferson Medical College and the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia have found that zinc treatment may help prevent esophageal and oral cancers in those individuals at high risk.
Oral and esophageal cancers are associated with nutritional zinc deficiency, and a rise in the expression of the enzyme COX-2 is connected with these cancers. Louise Fong, Ph.D., assistant professor of microbiology and immunology at Jefferson Medical College of Thomas Jefferson University, and her co-workers have found that zinc given orally to zinc-deficient rats reverses the development of precancerous conditions in the esophagus and tongue and reverses the high expression of COX-2 there as well.
These findings suggest that zinc supplements may prevent the development of esophageal or oral cancers, particularly in developing countries where zinc deficiency is a problem. The researchers reported their findings January 5, 2005 in the Journal of the National Cancer Institute. Zinc in the diet comes mostly from red meat and seafood. Whereas up to 10 percent of Americans have a zinc-deficient diet, as many as 2 billion individuals in developing countries are zinc-deficient. Epidemiological evidence show the incidence of esophageal and oral cancers is rising in recent years. As many as 13,000 Americans die from esophageal cancer each year.

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
