A group of investigators of the University of Cagliari found an interesting association between chemokinines and dementia in Down’s syndrome, which may have far reaching implications.
People with Down`s syndrome (DS) show early Alzheimer-like dementia. It has been suggested that the pro-inflammatory cytokine class plays a role in Alzheimer`s disease (AD). The study aims at verifying whether pro-inflammatory cytokines in DS are correlated with age, affective symptoms and intellectual decline to a different degree than in subjects with non-DS learning disabilities: Cases: 19 subjects with DS; controls: sex- and age-matched individuals with learning disabilities caused by perinatal ischaemic damage. The level of mental retardation was assessed according to DSM-IV; psychopathological symptoms were measured by the Assessment and Information Rating Profile. Serum levels of cytokines were determined with ELISA. DS patients showed higher levels of cytokines and chemokines, with the exception of RANTES; but the only significant difference detected was for MIP-1. A correlation between the degree of mental retardation and IL-6, and between MIP-l and age was found in patients with DS, but not in controls. The data obtained suggest a possible involvement of chemokines in the inflammatory and degenerative processes similar to AD in DS. Further longitudinal research is required to confirm these findings.

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....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
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...
