Plasmonic Modulation of Gold Nanoplates on Multiwavelength Emission.

Plasmonic regulation introduced by metallic nanoparticles is a useful method to improve the detection performance of plasmon-based systems. Herein, we observed a unique enhancement of surface plasmon-coupled emission (SPCE) using plate-shaped plasmonic nanostructures. By assembling Au nanoplates (Au NPLs) via electrostatic adsorption between the Au nanofilm and the quantum dot (QD) layer (630 nm), the fluorescence signal of SPCE was enhanced 90 times more than that of normal SPCE after the conditions were optimized.

Fluorescence enhancement of surface plasmon coupled emission by Au nanobipyramids and its modulation effect on multi-wavelength radiation.

Surface plasmon coupled emission (SPCE), a novel surface-enhanced fluorescence technique, can generate directional and amplified radiation by the intense interaction between fluorophores and surface plasmons (SPs) of metallic nanofilms. For plasmon-based optical systems, the strong interaction between localized and propagating SPs and "hot spot" structures show great potential to significantly improve the electromagnetic (EM) field and modulate optical properties. Au nanobipyramids (NBPs) with two sharp apexes to enhance and restrict the EM field were introduced through electrostatic adsorption to achieve a mediated fluorescence system, and the emission signal enhancement was realized by factors over 60 compared with the normal SPCE.

Genetic Profile and Clinical Characteristics of Brugada Syndrome in the Chinese Population.

Background: Brugada syndrome (BrS) is an inheritable arrhythmia syndrome that can lead to sudden cardiac death in patients while the heart structure is normal. However, the genetic background of more than 65% of BrS probands remains unclear.

Objectives: The purpose of this study is to report the variant spectrum in a Chinese cohort with suspected BrS and to analyze their distinct clinical and electrocardiographic features.

Autosomal dominant osteopetrosis type II resulting from a mutation in the gene: A case report.

Background: Osteopetrosis is a family of extremely rare diseases caused by failure of osteoclasts and impaired bone resorption. Among them, autosomal dominant osteopetrosis type II (ADO II), related to the chloride channel 7 () gene, is the most frequent form of osteopetrosis. In this study, we report a mutation of in a patient without the family history of ADO II.

Amplified Fluorescence by Hollow-Porous Plasmonic Assembly: A New Observation and Its Application in Multiwavelength Simultaneous Detection.

Surface plasmon coupled emission (SPCE) is a new analytical technique that provides increased and directional radiation based on the near-field interaction between fluorophores and surface plasmons but suffers from the limitation of insufficient sensitivity. The assembly of hollow-porous plasmonic nanoparticles could be the qualified candidate. After the introduction of gold nanocages (AuNCs), fluorescence signal enhancement was realized by factors over 150 and 600 compared with the normal SPCE and free space emission, respectively, with a fluorophore layer thickness of approximately 10 nm; hence, the unique enhancement of SPCE by the AuNCs effectively overcomes the signal quenching induced by resonance energy transfer (in normal SPCE).

(t, n) Threshold d-Level Quantum Secret Sharing.

Most of Quantum Secret Sharing(QSS) are (n, n) threshold 2-level schemes, in which the 2-level secret cannot be reconstructed until all n shares are collected. In this paper, we propose a (t, n) threshold d-level QSS scheme, in which the d-level secret can be reconstructed only if at least t shares are collected. Compared with (n, n) threshold 2-level QSS, the proposed QSS provides better universality, flexibility, and practicability.

Overweight and obesity associated with increased total serum calcium level: comparison of cross-sectional data in the health screening for teaching faculty.

Obesity is a risk of cardiovascular diseases. Our previous studies revealed that serum calcium level may have influence in the blood pressure to older male subjects. The aim of this study was to evaluate the relationship between total serum calcium level and overweight and obesity subjects.

Obesity detection rate among primary school students in the People's Republic of China: a meta-analysis.

Background: Obesity has become a major public health problem worldwide. The prevalence of obesity is rising alarmingly among children and adolescents in the People's Republic of China, with an estimated 120 million now in the obese range. It is estimated that 8% of children in the People's Republic of China are obese and 12% are overweight.

[Self-cleaning and antimicrobial properties of methacrylic acid coupled TiO(2)/PMMA denture base resin].

Purpose: To study the influence of TiO2 and methacrylic acid on self-cleaning and antimicrobial properties of denture base resin.

Methods: TiO2 (2%, 4%, 6%) and methacrylic acid were respectively added into two makers' denture base resins. The self-cleaning property was assayed with measuring the decomposition of methylthioninium chloride.
