First amphetamine-based long-acting stimulant offers all-day symptom control in children
A research team led by a Massachusetts General Hospital investigator has found that a long-acting form of the stimulant medication Adderall is effective in controlling symptoms of attention-deficit/hyperactivity disorder (ADHD) in children when taken in a single morning dose. The standard form of Adderall, which is made up of several amphetamine-based drugs, is only effective for four hours. This new formulation joins other long-acting stimulants, such as extended-release methylphenidate (Ritalin), in giving patients with ADHD a greater choice of medication. The report appears in the August issue of Pediatrics.
"Long-acting stimulants are very beneficial for children with ADHD, who otherwise have to go to the nurses office during the school day to receive their medication. And timed-release dosage avoids having frequent peaks and valleys of medication levels, giving the patient a more stable therapeutic environment," says Joseph Biederman, MD, director of Pediatric Psychopharmacology at MGH and the studys lead author. "This medication gives us another treatment opportunity for those who cannot tolerate other stimulant drugs."
More than 500 children aged 6 to 12 who met standard diagnostic criteria for ADHD enrolled in the study at 47 sites across the country. Participants were randomly divided into four groups, and after a one-week "washout" period in which all participants received a placebo medication, three of the four groups began taking a 10 mg daily dose of the timed-release medication. The fourth group continued on placebo. After a week of 10 mg dosage, two of the three medication groups switched to a 20 mg dosage. And after another week, one group advanced to a 30 mg daily dosage. The study was double-blinded, meaning that study participants, their parents and the treating physicians did not know what dosages participants were receiving.

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...
