About one in a hundred patients with apparently incurable non-small cell lung cancer (NSCLC) survive five or more years after being given relatively small doses of radiation therapy (RT) meant to ease symptoms, according to a new study. Published in the March 1, 2006 issue of CANCER, a peer-reviewed journal of the American Cancer Society, the study says a new subset of patients with NSCLC appears to have disease that is curable with minimal therapy, and may explain occasional cures attributed to unconventional therapies or faith healing.
NSCLC is by far the most common type of lung cancer. With an overall five year survival of only 40 percent, it is also one of the deadliest. If caught early, five year survival can reach 60 percent. Five year survival in farther advanced disease is approximately 15 percent.
Patients who are diagnosed with disease that is too advanced for curative treatment remain eligible for palliative therapies intended to provide symptom relief, including comparatively low doses of localized RT. Physicians have long made clinical observations that some patients receiving palliative RT long outlive their estimated survival and a few report even cures. Given that therapeutic doses of RT are much higher, it is not surprising that these reports require evidence-based confirmation.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
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...
