Waiting time distribution of solar energetic particle events modeled with a non-stationary Poisson process

open access: yes, 2014
We present a study of the waiting time distributions (WTDs) of solar energetic particle (SEP) events observed with the spacecraft $WIND$ and $GOES$. Both the WTDs of solar electron events (SEEs) and solar proton events (SPEs) display a power-law tail ...

Effective components of Chinese herbs reduce central nervous system function decline induced by iron overload

open access: yesNeural Regeneration Research, 2015
Abnormally increased levels of iron in the brain trigger cascade amplification in Alzheimer′s disease patients, resulting in neuronal death. This study investigated whether components extracted from the Chinese herbs epimedium herb, milkvetch root and ...

Kondo Metal and Ferrimagnetic Insulator on the Triangular Kagom\'e Lattice

open access: yes, 2012
We obtain the rich phase diagrams in the Hubbard model on the triangular Kagom\'e lattice as a function of interaction, temperature and asymmetry, by combining the cellular dynamical mean-field theory with the continuous time quantum Monte Carlo method ...

Protective effects of a polysaccharide from Spirulina platensis on dopaminergic neurons in an MPTP-induced Parkinson′s disease model in C57BL/6J mice

open access: yesNeural Regeneration Research, 2015
The present study aimed to determine whether a polysaccharide obtained from Spirulina platensis shows protective effects on dopaminergic neurons. A Parkinson′s disease model was established through the intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,

Dark matter and LHC phenomenology of a scale-invariant scotogenic model Supported in part by The National Key Research and Development Program of China (2017YFA0402200), the Grants (NSFC-11575089, NSFC-11025525) and the CAS Center for Excellence in Particle Physics (CCEPP)

open access: yesChinese Physics, 2019
We study the phenomenology of a model that addresses the neutrino mass, dark matter, and generation of the electroweak scale in a single framework. Electroweak symmetry breaking is realized via the Coleman-Weinberg mechanism in a classically scale invariant theory, while the neutrino mass is generated radiatively through interactions with dark matter ...

Curcumin pretreatment and post-treatment both improve the antioxidative ability of neurons with oxygen-glucose deprivation

open access: yesNeural Regeneration Research, 2015
Recent studies have shown that induced expression of endogenous antioxidative enzymes thr-ough activation of the antioxidant response element/nuclear factor erythroid 2-related factor 2 (Nrf2) pathway may be a neuroprotective strategy. In this study, rat

Ultra-narrow Negative Flare Front Observed in Helium-10830~\AA\ using the 1.6 m New Solar Telescope

open access: yes, 2016
Solar flares are sudden flashes of brightness on the Sun and are often associated with coronal mass ejections and solar energetic particles which have adverse effects in the near Earth environment.

Enhancing hippocampal blood flow after cerebral ischemia and vasodilating basilar arteries: in vivo and in vitro neuroprotective effect of antihypertensive DDPH

open access: yesNeural Regeneration Research, 2015
1-(2,6-Dimethylphenoxy)-2-(3,4-dimethoxyphenylethylamino)-propane hydrochloride (DDPH) is a novel antihypertensive agent based on structural characteristics of mexiletine and verapamine.

Neuroprotective effect of rapamycin on spinal cord injury via activation of the Wnt/β-catenin signaling pathway

open access: yesNeural Regeneration Research, 2015
The Wnt/β-catenin signaling pathway plays a crucial role in neural development, axonal guidance, neuropathic pain remission and neuronal survival. In this study, we initially examined the effect of rapamycin on the Wnt/β-catenin signaling pathway after ...

Compensatory recombination phenomena of neurological functions in central dysphagia patients

open access: yesNeural Regeneration Research, 2015
We speculate that cortical reactions evoked by swallowing activity may be abnormal in patients with central infarction with dysphagia. The present study aimed to detect functional imaging features of cerebral cortex in central dysphagia patients by using
