Imatinib, a drug that blocks the protein made by a particular cancer-causing gene, has revolutionized the treatment and prognosis of patients with CML. Now up to 93 percent of patients who take the drug as initial therapy for CML survive at least eight years, whereas prior to imatinib, patients survived an average of only three to six years.
While imatinib is now the standard drug given after a diagnosis of CML, approximately 15,000 to 20,000 patients in the United States may have started taking imatinib after failing to respond to the previous standard drug for CML, interferon. Like patients who now take imatinib as initial therapy for their cancer, these patients seem to respond well to imatinib, at least in the short term; however, little is known about their long-term prognosis.
To investigate, Hagop Kantarjian, MD, of the University of Texas MD Anderson Cancer Center in Houston, and his colleagues analyzed 368 CML patients from their institution who started taking imatinib after failing to respond to interferon. The team estimated that 68 percent of patients survived for at least 10 years. Previous research indicates that only 20 to 30 percent of patients who do not respond to interferon therapy and have no access to imatinib survive this long.
According to the authors, these findings suggest that most patients can benefit from imatinib after unsuccessful interferon treatments, and they do not have to consider other therapeutic options.

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...
