Findings published in this months issue of Clinical Cancer Research and featured on the journals cover, may bring researchers one-step closer to the development of tumor markers to detect colon cancer early, before it has had a chance to spread and when it is easier to cure, say researchers from the University of Pittsburgh Cancer Institute (UPCI). These tumor markers – elevated levels of proteins or other substances in the blood, urine or tissue that indicate the presence of cancer – also could help identify which patients with colon cancer are more likely to develop recurrent disease.
In the study, Robert Getzenberg, Ph.D., senior author and associate professor of urology, pathology and pharmacology at the University of Pittsburgh and co-director, Prostate and Urologic Cancer Program, UPCI and colleagues analyzed cancerous tissue resulting from colon cancer that had spread to the liver – the most common site for colon cancer to recur – and found three proteins present in the diseased liver tissue that were not present in normal liver tissue. The findings add to previous findings published earlier this year in the journal Cancer Research in which the same researchers identified four different proteins present in colon cancer tumor samples that were not found in normal colon tissue.
"Identifying a specific and sensitive tumor marker that would allow reliable early detection of colon cancer and predict the potential for the cancer to spread or recur would be of great benefit to patients," said Dr. Getzenberg. "Early diagnosis of recurrent colon cancer is critical to effective treatment of the disease, however, colon cancer metastases are very difficult to pick up early. Thirty-five to 40 percent of all patients with colon cancer have recurrent disease and the majority of these patients cannot be cured and will eventually die."

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel’s Swiss Nanoscience Institute network have reported the results in the journal Science Advances.
Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. Molecules and sections of macromolecules are...
