Red-orange photoluminescence and dielectric relaxation of Eu3+-doped Bi2Ti2O7 pyrochlore structure thin films
Publication date: Available online 13 July 2015 Source:Materials Chemistry and Physics Author(s): Fanfan Li , Xiang Liu , Jianxiong Zhao , Ling Liu , Shuai He , Dinghua Bao Eu3+-doped Bi2Ti2O7 pyrochlore structure thin films were prepared by a chemical solution deposition method. The red-orange photoluminescence and dielectric relaxation of Bi2−x Eu x Ti2O7 thin films have been investigated in terms of Eu3+ doping content (x = 0, 0.1, 0.2, 0.3, 0.4, 0.5, and 0.6) and annealing temperature. The crystallinity and surface morphology of the thin films were evaluated by X-ray diffractometer and field emission scanning ele...

Paradoxical pain perception in PTSD: The unique role of anxiety and dissociation
Posttraumatic stress disorder (PTSD) and chronic pain often co-occur and exacerbate each other. Elucidating the mechanism of this co-occurrence therefore has clinical importance. Previously, PTSD patients with chronic pain were found to demonstrate a unique, paradoxical pain profile: hyper-responsiveness together with hyposensitivity to pain. Our aim was to examine whether two seemingly paradoxical facets of PTSD - anxiety and dissociation - underlie this paradoxical profile.PTSD patients (n=32) and healthy controls (n=43) underwent psychophysical testing and completed questionnaires.

Self-degrading niosomes for encapsulation of hydrophilic and hydrophobic drugs: An efficient carrier for cancer multi-drug delivery
In this study, we have examined the encapsulation and release of hydrophilic and hydrophobic drugs in self-degrading niosomes as a unique method for anticancer therapy. Niosomes were prepared by amphiphilic self-assembly of Tween 80 and cholesterol through film hydration method. Encapsulation studies with two active molecules curcumin and doxorubicin hydrochloride (Dox) showed that curcumin is supposed to accumulate in the shell whereas Dox accumulates in the inner aqueous core of the niosome. Confocal studies indicated that nile red adsorbs preferentially to the head group of the Tween 80 and forms two separate layers in ...

The design of bipolar spin semiconductor based on zigzag–edge graphene nanoribbons
Publication date: November 2015 Source:Carbon, Volume 94 Author(s): X.Q. Deng , Z.H. Zhang , G.P. Tang , Z.Q. Fan , C.H. Yang , L. Sun Using first-principle methods, we investigate the magnetism properties of zigzag–edge graphene nanoribbons (ZGNRs) with a nanopore, and find that edges of such a nanopore show important effects although the electron transport is mainly along the outer edge of ZGNR. The robust bipolar spin semiconductor can be obtained when the edges of such a nanopore are varied, where both spin states have a gap but can relatively shift. We speculate that bipolar spin semiconductor behavior is related ...

Validation of the Hospital Anxiety and Depression Scale (HADS) in Patients with Acute Low Back Pain
The Hospital Anxiety and Depression Scale (HADS) is a self-report instrument used to evaluate depression and anxiety in clinical research. The HADS has advantages over other assessments of anxiety and depression; it is efficient in assessing both anxiety and depression with a total of 14 items, and was originally developed on a general medical rather than psychiatric sample. However, the HADS has not been evaluated specifically for use in clinical trials of acute pain. Validation analyses were conducted on data from a randomized, double-blind, parallel-group study of tapentadol immediate release (IR) vs. (Source: The Journal of Pain)

Carbon nanotubes enhance intercalated disc assembly in cardiac myocytes via the β1-integrin-mediated signaling pathway.
Abstract Carbon nanotubes (CNTs) offer a new paradigm for constructing functional cardiac patches and repairing myocardial infarction (MI). However, little is known about how CNTs enhance the mechanical integrity and electrophysiological function of cardiac myocytes. To address this issue, we investigated the regularity and precise mechanism of the influence of CNTs on the assembly of intercalated disc (IDs). Here, single walled CNTs incorporated into collagen substrates were utilized as growth supports for neonatal cardiomyocytes, which enhanced cardiomyocyte adhesion and maturation. Furthermore, through the use o...

Salvaging brain ischemia by increasing neuroprotectant uptake via nanoagonist mediated blood brain barrier permeability enhancement.
Abstract Ischemic stroke is a leading cause of adult disability and cognitive impairment worldwide. Neuroprotective therapy aims to save neurons by impeding the deleterious ischemic insults. However, the low efficiency of the neuroprotectants crossing blood brain barrier (BBB) prevents their clinical translation. In this work, a nanoagonist (NA) was developed to enhance neuroprotectant uptake by specifically increasing BBB permeability in brain ischemia. This NA first targeted ischemic brain vasculatures, temporarily opened local BBB by activating adenosine 2A receptors, and up-regulated the neuroprotectant uptake ...
