Magnetic catalysts (MCs) derived from iron-rich drinking water treatment residuals (WTRs) were prepared through pyrolysis treatment and introduced as activators of peroxymonosulfate (PMS) for refractory atrazine (ATZ) degradation. Comprehensive characterization analysis indicated that pyrolytic temperature could manipulate the crystalline structure evolution of the MCs and influence their physicochemical and catalytic properties. The catalytic performances of the as-prepared samples pyrolyzed at 600 °C (MC-600) and 1000 °C (MC-1000) were evaluated, and MC-1000 exhibited far more excellent catalytic reactivity than MC-600 in PMS oxidation system.

Caffeine-stimulated muscle IL-6 mediates alleviation of non-alcoholic fatty liver disease.

Biochim Biophys Acta Mol Cell Biol Lipids 2018 Dec 12. Epub 2018 Dec 12.

Key Laboratory of Pu-erh Tea Science, the Ministry of Education, Yunnan Agricultural University, Kunming 650201, China; State Key Laboratory for Conservation and Utilization of Bio-Resources in Yunnan, Kunming, China; Pu'erh Tea Research Institute, Pu'erh, China. Electronic address:

Caffeine intake is associated with a reduced risk developing non-alcoholic fatty liver disease (NAFLD), but the underlying molecular mechanisms remain to be fully elucidated. We report here that caffeine markedly improved high fat diet-induced NAFLD in mice resulting in a 10-fold increase in circulating IL-6 levels, leading to STAT3 activation in the liver. Interestingly, the expression of IL-6 mRNA was not increased in the liver, but increased substantially in the muscles of caffeine-treated mice. Read More

A framework for offline evaluation and optimization of real-time algorithms for use in neurofeedback, demonstrated on an instantaneous proxy for correlations.

Neuroimage 2018 Dec 12. Epub 2018 Dec 12.

Section on Functional Imaging Methods, National Institute of Mental Health, National Institutes of Health, Bethesda, MD, 20892, USA.

Interest in real-time fMRI neurofeedback has grown exponentially over the past few years, both for use as a basic science research tool, and as part of the search for novel clinical interventions for neurological and psychiatric illnesses. In order to expand the range of questions which can be addressed with this tool however, new neurofeedback methods must be developed, going beyond feedback of activations in a single region. These new methods, several of which have already been proposed, are by their nature complex, involving many possible parameters. Read More

Electrophysiological and behavioral measures of some speech contrasts in varied attention and noise.

Hear Res 2018 Dec 6;373:1-9. Epub 2018 Dec 6.

Lund University Department of Psychology, Paradisgatan 5, Lund, 22100, Sweden. Electronic address:

This paper investigates the salience of speech contrasts in noise, in relation to how listening attention affects scalp-recorded cortical responses. The contrasts that were examined with consonant-vowel syllables, were place of articulation, vowel length and voice-onset time (VOT) and our analysis focuses on the correspondence between the effect of attention on the electrophysiology and the decrement in behavioral results when noise was added to the stimuli. Normal-hearing subjects (n = 20) performed closed-set syllable identification in no noise, 0, 4 and 8 dB signal-noise ratio (SNR). Read More
