A tunable graphene plasmonic Y-branch switch at THz wavelengths is proposed. The effects of magnetic and electric biasing are studied to harness the transmission of the transverse electric and magnetic guided mode resonances. In the structure, hexagonal boron nitride is utilized as a substrate for graphene. The application of hexagonal boron nitride, with the advantages of high mobility and ultralow ohmic loss, introduces a promising alternative substrate for graphene. Analytical and numerical results show that, by slight variation of the doping level in graphene through magnetic and electric biasing, the characteristics of the propagation of the guided mode resonances can be manipulated...

Alzheimer's disease (AD) is a neurodegenerative disorder known for the presence of amyloid beta plaques resulting from the sequential action of β-secretase and γ-secretase on amyloid precursor protein. We developed and synthesized, through click reactions, a new family of iminochromene carboxamides containing different aminomethylene triazole. The BACE1 inhibition, neuroprotective capacity and metal chelation of these derivatives make them ideal candidates against AD. Most of the synthesized compounds were shown to have potent BACE1 inhibitory activity in a FRET assay, with an IC50 value of 2...

Myocardial cell apoptosis is very common in the clinic, and is caused by myocardial ischemia reperfusion injury (MIRI). There are different degrees of cell apoptosis in MIRI. However, initiation of the signal transduction mechanism of myocardial cell apoptosis is unclear. The present research confirmed that acupuncture and moxibustion are effective interventions for cell apoptosis in MIRI through three approaches:the death receptor pathway, mitochondrial pathway and endoplasmic reticulum pathway. In this paper, the authors summarize the mechanism characteristics of acupuncture and moxibustion in MIRI cell apoptosis, and discuss the signal transduction pathways involved in the effects of acupuncture and moxibustion in MIRI cell apoptosis, in order to provide new ideas and evidence for the clinical application of acupuncture and moxibustion to prevent cell apoptosis in MIRI...

A 75-year-old man was admitted to our hospital in May 2016 with progressive shortness of breath. We considered him to be experiencing acute heart failure caused by atrial fibrillation. Contrast-enhanced computed tomography showed a hypodense mass involving the right atrium and left ventricle, pericardial effusion, and lymphadenopathy of the groin. Histological finding from the groin and pericardial effusion analysis showed diffuse large B-cell lymphoma(DLBCL). We thus diagnosed this patient with cardiac tamponade owing to the involvement of the heart by DLBCL...

Zeinab Jafari, Abbas Zarifkar, Mehdi Miri
Regarding the importance of bandwidth and capacity expansion in communication systems, a novel mode division (de)multiplexer based on subwavelength grating (SWG) is proposed. SWG-based devices could have smaller sizes, be much more fabrication-tolerant, and have much wider bandwidths due to the reduced confinement of the field and dispersion. It is also feasible to reduce the loss of a SWG-based device by tuning the duty cycle of the grating. Owing to these properties of SWGs, we have designed a compact fabrication-tolerant two-mode division (de)multiplexer...

In this article, we introduce and apply a methodology, based on density functional theory and the gauge-including projector augmented wave approach, to explore the effects of packing interactions on solid-state nuclear magnetic resonance (NMR) parameters. A visual map derived from a so-termed "magnetic shielding contribution field" can be made of the contributions to the magnetic shielding of a specific site-partitioning the chemical shift to specific interactions. The relation to the established approaches of examining the molecule to crystal change in the chemical shift and the nuclear independent chemical shift is established...

Childhood lead (Pb2+) intoxication is a public health problem of global proportion. Lead exposure during development produces multiple effects on the central nervous system including impaired synapse formation, altered synaptic plasticity, and learning deficits.In primary hippocampal neurons in culture and hippocampal slices, Pb2+ exposure inhibits vesicular release and reduces the number of fast-releasing sites, an effect associated with Pb2+ inhibition of NMDA receptor-mediated trans-synaptic Brain-Derived Neurotrophic Factor (BDNF) signaling...
