In conclusion, treatment with a high-fiber, low-fat diet for 8 weeks effectively improved periodontal disease markers as well as metabolic profiles, selleck chemicals llc at least in part, by effects other than the reduction of total energy intake. (C) 2014 Elsevier Inc. All rights reserved.”
“We have examined the effects of core-shell intermixing on the dynamical magnetism of gamma-Fe2O3/MnO nanoparticles. The core and shell phases were identified using x-ray diffraction, and x-ray absorption spectroscopy identified Mn ions in both octahedral and tetrahedral sites, consistent with a significant amount of substitution at the core-shell interface to form an Fe/Mn-ferrite. The dynamical
response was probed by Mossbauer spectroscopy, which decouples surface and core spins, and suggested a change in the relaxation behaviour among the spin populations within gamma-Fe2O3/MnO relative to the gamma-Fe2O3 seed particles. Interestingly, the magnetic
relaxation effects at the atomic scale, measured via Mossbauer spectroscopy, AR-13324 were enhanced, indicating that the addition of an MnO shell and intermixing affected the dynamical freezing process which altered the surface magnetism of the gamma-Fe2O3 core. Our results show that both the MnO shell and the interfacial intermixed layer are important in determining the core-shell nanoparticle magnetism. (C) 2015 AIP Publishing LLC.”
“This study explores the possibility of noninvasively inducing long-term changes in human corticomotor excitability by means of a brain-computer interface, which enables users to exert internal control over the cortical rhythms recorded from the scalp. We demonstrate that self-regulation of electroencephalogram rhythms in quietly sitting, naive humans significantly affects the subsequent corticomotor response to transcranial magnetic stimulation, producing durable and correlated changes in neurotransmission. Specifically, we show that the intrinsic suppression of alpha cortical rhythms can in itself produce robust increases STA-9090 in corticospinal excitability
and decreases in intracortical inhibition of up to 150%, which last for at least 20 min. Our observations may have important implications for therapies of brain disorders associated with abnormal cortical rhythms, and support the use of electroencephalogram-based neurofeedback as a noninvasive tool for establishing a causal link between rhythmic cortical activities and their functions.”
“Background: Deliberative public engagement has been proposed for policy development, where issues are complex and there are diverse public perspectives and low awareness of competing issues. Scholars suggest a range of potential outcomes for citizens and government agencies from involvement in such processes. Few studies have examined outcomes from the perspective of citizen participants in deliberative processes.
