Half of New York City residents over 50, the age at which the American Cancer Society recommends beginning screening tests, have not received a colon cancer-screening test within the recommended time intervals, according to a new study. The report, published in the September 1, 2005 issue of CANCER, a peer-reviewed journal of the American Cancer Society, says those New Yorkers least likely to have received screening include those with low-income, the uninsured, Asians and current smokers.
More than 56,000 Americans are expected to die this year from colorectal cancer, making it the third leading cause of cancer death in both men and women. Screening tests, which include the fecal occult blood test (FOBT), flexible sigmoidoscopy (FS), and colonoscopy, have been proven to reduce mortality and be more cost-effective than breast cancer screening tests, which are more widely used. Current screening guidelines recommend annual FOBT, FS every 5 years, or a colonoscopy every 10 years, but only 53 percent of Americans receive timely screening.
New York City is unique in that there is high density of gastroenterologists and endoscopy labs to provide access to colonoscopy services. In 2003, the city adopted new screening guidelines--a colonoscopy every 10 years or FOBT every year as an acceptable, although not optimal, alternative for those unwilling or unable to undergo colonoscopy. To evaluate the effect of this change, Lorna Thorpe, Ph.D. of the New York City Department of Health and Mental Hygiene and researchers from leading hospitals and academic institutions conducted a baseline telephone survey of the colon cancer screening habits of 9,802 New York City residents.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
