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."

Highly precise wiring in the Cerebral Cortex
21.09.2017 | Max-Planck-Institut für Hirnforschung
Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
