The reinforcement effect of graphene oxide nanosheets on the mechanical properties of an epoxy coating has been extensively studied. However, the effect of graphene oxide quantum dot (GOQD) as a new unique carbon based nanomaterial (with lateral dimension of 5-6nm and thickness of one carbon atom) on the mechanical properties of epoxy coating has not been reported and compared with GO yet. So this study aims at fabrication of a high-performance polymer composite with unique mechanical properties using GOQD nanosheets...

Phosphate (P) removal is significant for the prevention of eutrophication in natural waters. In this paper, a novel adsorbent for the removal of P from aqueous solution was synthesized by loading zirconium oxide and iron oxide onto activated carbon nanofiber (ACF-ZrFe) simultaneously. The adsorbent was characterized by scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy and X-ray photoelectron spectroscopy (XPS). The results showed that P adsorption was highly pH dependent and the optimum pH was found to be 4...

Ratiometric fluorescence sensor exhibits advantages of sensitive response, high anti-interference ability and naked eye visualization owing to multiple independent emission peaks utilized for results analysis. To achieve such multi-emission probe, the traditional methods have involved simple mixing of two emitters or tedious synthesis processes of hybrid material. However, these probes often have problems of inconstant emission strength ratio, low light-stability, and complicated synthetic process, which limit their applications in practical field...

The sensitizing propensity of radio-/photosensitizing nucleoside depends on DNA sequence surrounding a sensitizer. Therefore, in order to compare sensitizers with regard to their ability to induce a DNA damage one has to study the sequence dependence of damage yield. However, chemical synthesis of oligonucleotides labeled with sensitizing nucleosides is hindered due to the fact that a limited number of such nucleoside phosphoramidites are accessible. Here, we report on a chemically-enzymatic method, employing a DNA polymerase and ligase, that enables a modified nucleoside, in the form of its 5'-triphosphate, to be incorporated into DNA fragment in a pre-determined site...

Lignans and neolignans are principal bioactive components of Linum usitatissimum L. (Flax), having multiple pharmacological activities. In present study, we are reporting an authoritative abiotic elicitation strategy of photoperiod regimes along with UV-C radiations. Cell cultures were grown in different photoperiod regimes (24h-dark, 24h-light and 16L/8D h photoperiod) either alone or in combination with various doses (1.8-10.8kJ/m(2)) of ultraviolet-C (UV-C) radiations. Secoisolariciresinol diglucoside (SDG), lariciresinol diglucoside (LDG), dehydrodiconiferyl alcohol glucoside (DCG), and guaiacylglycerol-β-coniferyl alcohol ether glucoside (GGCG) were quantified by using reverse phase-high performance liquid chromatography (RP-HPLC)...

REVIEW
Van-Thuan Nguyen, Young Seop Kwon, Man Bock Gu
Aptasensors are promising biosensors, which take advantage of using aptamers as a recognition element. The combination of the excellent characteristics of aptamers and the leading detection platform techniques, such as optical, electrochemical with nanomaterial-integrated, or mass-sensitive techniques with high sensitivity and specificity draws a promising view for the application of the aptasensors for the detection of harmful small toxic chemicals and real-time monitoring in the environments. In spite of attraction of aptasensors, application of them is limited to the complex environment due to the facts that how the immobilization of aptamers onto the surface affects the functions of aptamers and their structures for the detection of environmental contaminants are not clearly known...

The proliferation of new psychoactive substances (NPS) has been a global trend in drug abuse and its regulation has been a worldwide concern. There is no doubt that it is necessary to share information related to these emerging substances between countries and continents for the effective regulation of NPS. With efforts for the efficient regulation of NPS, many studies and information have been published for the prevalence of NPS in the United States and other countries in Europe and Oceania. However, there is lack of information available for the prevalence of NPS in Asian and African countries...

Personal goals/plans play a central role in personal recovery and psychiatric rehabilitation of persons with mental illnesses. Yet, few studies have explored whether perceiving practitioners' assistance towards the pursuit of goals are associated with personal recovery and other favorable rehabilitation outcomes. A total of 2121 mental health consumers, of which 1222 use supported-housing services and 899 use group-home services, completed self-report questionnaires as part of a larger quality-assurance study conducted during the years 2013-2014...

MENK, an endogenous opioid peptide has been reported to have many immunological and antitumor activities. So far the detailed mechanisms of antitumor through regulating DCs by MENK have not been elucidated yet. The aim of this work was to investigate the antitumor mechanisms of MENK via regulating DC. The monitoring methods, such as ELISA, MTS assay, CFSE, Real-time PCR and Western blot were included in our research. We found bone marrow derived dendritic cells (BMDCs) in 36 female C57BL/6 mice treated with MENK enhanced expression of key surface molecules, increased production of critical cytokines reduced endocytosis of FITC-dextran, upregulated TLR4 through MyD88/NF-κB signaling pathway and mounted higher antitumor activity...

PURPOSE: In spite of the fact that epilepsy is a concealable stigmatized identity, there is little evidence pertaining to disclosure management in adults living with epilepsy. We determined the factors contributing to disclosure management strategies in adults living with well-controlled epilepsy. METHODS: This was a cross-sectional multicenter study. Korean adults whose seizures had remitted for at least one year participated in this study. Using statistical analyses, we determined whether disclosure management behaviors measured using the Disclosure Management Scale (DMS) were related to demographic, clinical, and psychosocial variables...

BACKGROUND: Cannabidiol (CBD) is a naturally occurring constituent of the marijuana plant. In the past few years, there has been great interest in the therapeutic effects of isolated CBD and it is currently being explored for numerous disease conditions (e.g., pain, epilepsy, cancer, various drug dependencies). However, CBD remains a Schedule I drug on the U.S. Controlled Substances Act (CSA). Despite its status, there are no well-controlled data available regarding its abuse liability...

This work reports on a targeted and controlled drug delivery system based on protein decorated mesoporous silica nanoparticles (MSNs). In this system, transferrin (Tf), a naturally existing protein, is grafted on the surfaces of MSNs via redox-cleavable disulfide bonds, serving as both a capping agent and a targeting ligand simultaneously. The uniform particles with ordered mesoporous structures and the successful construction of the Tf/MSN hybrid nanocarriers can be confirmed through combined techniques. It is found that the model anticancer drug doxorubicin (DOX) can be efficiently encapsulated in the MSNs in the absence of glutathione (GSH), and a burst release of DOX is observed when the system is exposed to GSH, indicating good capping efficiency of Tf and redox-responsive release of DOX...
