Although rapid progress has been made in understanding the interaction of nanoparticles (NPs) with lipid membrane, little is known about the interaction between neighboring NPs on the membrane. With the aid of computer simulation techniques, in this work we systematically investigate the membrane mediated interaction between anisotropic NPs with at least one dimension with the size of several n...

Iron oxide nanoparticles (NPs) are commonly utilized for biomedical, industrial, and commercial applications due to their unique properties and potential biocompatibility. However, little is known about how exposure to iron oxide NPs may affect susceptible populations such as pregnant women and developing fetuses. To examine the influence of NP surface-charge and dose on the developmental toxic...

It has recently been shown that surface plasmon microscopy (SPM) allows single nanoparticles (NPs) on sensor surfaces to be detected and analyzed. The authors have applied this technique to study the adsorption of single metallic and plastic NPs. Binding of gold NPs (40, 60 and 100 nm in size) and of 100 nm polystyrene NPs to gold surfaces modified by differently ω-functionalized alkyl thiols w...

UNLABELLED WHAT IS KNOWN ON THE SUBJECT?: Novel psychoactive substances (NPS) include synthetic drugs mimicking the effects of illicit drugs, e.g. synthetic cannabinoids, and herbs such as Salvia divinorum. NPS are substances that can trigger hallucinations and other effects altering the mind, and are currently uncontrolled by the United Nations' 1961 Narcotic Drugs/1971 Psychotropic Substances...

during the past few years, there has been an increasing recognition that internet is playing a significant role in the synthesis, the distribution and the consumption of novel psychoactive substances (nps).the aim of this study was to assess the online availability of nps in persian language websites.the google search engine was used to carry out an accurate qualitative assessment of informatio...

In this paper, we report the first time preparation of SnO2 nanoparticles (NPs) using a green chemistry method. The leaf extract of Plectranthus amboinicus was used as reducing and stabilization agent for synthesizing SnO2 NPs. The synthesized SnO2 NPs were characterized by SEM, EDX, XRD and UV-vis spectroscopy. Results showed that the biosynthesized SnO2 NPs owing a high purity. The photocatal...

The toxicity of CuO nanoparticles (CuO NPs) to human hepatocarcinoma (HepG2) cells was investigated in this study. CuO NPs (1 40 mg/L) had significant toxicity to HepG2 cells. The antioxidant N-acetyl-L-cysteine (NAC) significantly reduces the cytotoxicity induced by the CuO NPs, supporting the hypothesis that oxidative stress contributes to the cytotoxicity of CuO NPs. To further explore the o...

OBJECTIVE To examine role transition and support requirements for nurse practitioner (NP) graduates in their first year of practice from the perspectives of the NPs and coparticipants familiar with the NPs' practices; and to make recommendations for practice, education, and policy. DESIGN Descriptive qualitative design informed by focused ethnography and narrative analysis using semistructure...

The temporal-spatial interaction of land cover and non-point source (NPS) nutrient pollution were analyzed with the Soil and Water Assessment Tool (SWAT) to simulate the temporal-spatial features of NPS nutrient loading in the upper stream of the Yellow River catchment. The corresponding land cover data variance was expressed by the normalized difference vegetation index (NDVI) that was calcula...

23 Amygdala plasticity is an important contributor to the emotional-affective dimension of 24 pain. Recently discovered neuropeptide S (NPS) has anxiolytic properties through 25 actions in the amygdala. Behavioral data also suggest antinociceptive effects of centrally 26 acting NPS, but site and mechanism of action remain to be determined. This is the first 27 electrophysiological analysis of p...
