Fewer than half of patients diagnosed with colorectal cancer had received a screening procedure at least six months prior to their diagnosis, according to a new study. Researchers writing in the February 15, 2005 issue of CANCER, a peer-reviewed journal of the American Cancer Society, further say almost 94 percent of colorectal cancer patients had either not undergone a colonoscopy at all, or not until having the procedure that led to their diagnosis.
Professional societies unanimously recommend colorectal cancer screening in older adults. The premise is mortality and morbidity is reduced when a premalignant growth, which is generally at an earlier stage, is detected and treated. Clinicians can use tests as simple as the fecal occult blood test (FOBT), which is the cheapest but least sensitive test, to tests that examine part of the colon with the sigmoidoscopy, or all of it with a colonoscopy or barium enema. The colonoscopy is the most sensitive test.
In order to characterize the use of the various screening tests in the population and their association with cancer stage, Gregory S. Cooper, M.D. and Jonathan D. Payes, M.S. of the University Hospitals of Cleveland and Case Western Reserve University reviewed the screening history and cancer stage of 5,806 elderly patients diagnosed with colorectal cancer.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
