Graphene oxide functionalized silica microspheres (GO@SiO2 ) were synthesized based on condensation reaction between amino from aminosilica particles and carboxyl groups from GO. Reduction of GO@SiO2 with hydrazinium hydroxide generated graphene modified silica particles (G@SiO2 ). GO@SiO2 and G@SiO2 packed capillary columns for capillary electrochromatography were thereafter fabricated by pressure slurry packing with single-particle frits. GO of 0.3 mg mL-1 in dispersion solution for GO@SiO2 synthesis was considered as a compromise between retaining and column efficiency whereas GO@SiO2 of 20 mg mL-1 in slurries for column packing was chosen for a homogenous and tight bed...

Mental disorders, such as dementia and depression, are beside chronic somatic diseases, the most common problem in residents of longterm care facilities (LTCF). Late-life depression refers to depressive symptoms that arise in adults older than 65 years. According to literature review, older people tend to differ from middle-aged adults in presentation of depression. AIM: Mental disorders, such as dementia and depression, are beside chronic somatic diseases, the most common problem in residents of longterm care facilities (LTCF)...

The δ subunit-containing γ-Aminobutyric acid type A receptors (δ-GABAARs) are located at extrasynaptic sites and persistently active in the control of neuronal excitability. Here we recorded primary afferent C fiber-evoked field potentials in the superficial dorsal horn of rat spinal cords in vivo, and investigated the possible influence of δ-GABAARs activities on nociceptive synaptic transmission. We found that δ-GABAARs-preferring agonist THIP, when topically applied onto spinal cord dorsum, inhibited the basal synaptic responses in a dose-dependent manner...

This study aimed to provide a greater understanding of the systemic factors involved in coal mine accidents and to examine the relationships between the contributing factors across all levels of the system. Ninety-four extraordinarily major coal mine accidents that occurred in China from 1997 to 2011 were analyzed using the human factors analysis and classification system (HFACS). The empirical results showed that the frequencies of unsafe behaviors, inadequate regulation, and failure to correct unsafe behaviors were the highest among five levels, fourteen categories, and forty-eight indicators, respectively...

Amnestic Alzheimer's disease (AD) is characterized by early atrophy of the hippocampus and medial temporal lobes before spreading to the neocortex. In contrast, nonamnestic Alzheimer's patients have relative sparing of the hippocampus, but the pattern in which the disease spreads is unclear. We examined spreading disease in nonamnestic AD using a novel magnetic resonance imaging-based analysis adapted from pathologic staging studies, applied here to cross-sectional imaging data. We selected 240 T1-weighted scans from 129 patients with pathology confirmed by autopsy or cerebrospinal fluid, and atrophy maps were computed relative to 238 scans from 115 elderly controls...

OBJECTIVE: An amplitude growth function (AGF) shows the amplitude of an electrically evoked compound action potential (eCAP) as a function of the stimulation current. AGFs can be used to derive the eCAP threshold, which represents the minimum amount of current needed to elicit a measurable eCAP. eCAP thresholds have been widely used clinically to, for example, assist with sound processor programming. However, no eCAP precision has been included to date. The aim of this study was to investigate the precision of eCAP thresholds and determine whether they are precise enough for clinical use...

Animal aggregations are visually striking, and as such are popular examples of collective behavior in the natural world. Quantitatively demonstrating the collective nature of such groups, however, remains surprisingly difficult. Inspired by thermodynamics, we applied topological data analysis to laboratory insect swarms and found evidence for emergent, material-like states. We show that the swarms consist of a core "condensed" phase surrounded by a dilute "vapor" phase. These two phases coexist in equilibrium, and maintain their distinct macroscopic properties even though individual insects pass freely between them...

Poly(lactic acid) (PLA) is a biodegradable and biocompatible polyester widely used in biomedical applications. Unfortunately, this biomaterial suffers from some shortcomings related with the absence of both bioactivity and antibacterial capacity. In this work, composites of PLA with either graphene oxide (GO) or thermally reduced graphene oxide (TrGO) were prepared by melt mixing to overcome these limitations. PLA composites with both GO and TrGO inhibited the attachment and proliferation of E. coli and S. aureus bacteria depending on the kind and amount of filler...

Free, 3-D interceptive movements are difficult to visualize and quantify. For ball catching, the endpoint of a movement can be anywhere along the target's trajectory. Furthermore, the hand may already have begun to move before the subject has estimated the target's trajectory, and the subject may alter the targeted position during the initial part of the movement. We introduce a method to deal with these difficulties and to quantify three movement phases involved in catching: the initial, non-goal-directed phase; the goal-directed phase, which is smoothly directed toward the target's trajectory; and the final, interception phase...

Hinge-based Ankle Foot Orthosis (HAFO) is one of the most common non-surgical solutions for the foot drop. In conventional HAFOs, the ankle joint is almost locked, and plantar flexion is restricted due to the high stiffness of the hinge mechanism. This often leads to a rigid walking gate cycle, poor muscle activity, and muscle atrophy. Since the ankle torque-angle loop has a non-linear profile, the use of a superelastic NiTi spring within the hinge, due to its nonlinear behavior, could recreate a close-to-normal stiffness of the normal ankle joint, which, in turn, could create a more natural walk...

The current study describes a trial-based functional analysis of problem behavior conducted in a home setting for a 7-year-old girl with autism. Problem behavior was occasioned by interruptions to an ongoing activity. Advance notice, in the form of a 2-min warning, and the sound of a timer were used to signal termination of a current activity and were effective at reducing problem behavior along with increasing compliance to the interruptive demands. A trial-based functional analysis, which are not common in the applied literature, was conducted in a home setting for young girl with autism, using antecedent and consequence modifications described by Hagopian, Bruzek, Bowman, and Jennett (2007), identified the variables that occasioned and maintained problem behavior were interruptions to an ongoing activity followed by regaining uninterrupted access to the previous activity...

In their 2016 article, "Navigating a Managed Care Peer Review: Guidance for Clinicians Using Applied Behavior Analysis [ABA] in the Treatment of Children on the Autism Spectrum," Papatola and Lustig provide an overview of the managed care process, discuss the medical necessity of ABA, and offer guidance to clinicians on how to navigate the managed care peer review process. Given that the authors are employed by a large international health insurance carrier and conduct peer reviews on behalf of that organization, this response seeks to provide guidance from both the clinical and public policy perspectives that reflect best practices in the field of autism treatment...

In biological membranes, many factors such as cytoskeleton, lipid composition, crowding, and molecular interactions deviate lateral diffusion from the expected random walks. These factors have different effects on diffusion but act simultaneously, so the observed diffusion is a complex mixture of diffusive behaviors (directed, Brownian, anomalous, or confined). Therefore, commonly used approaches to quantify diffusion based on averaging of the displacements such as the mean square displacement, are not adapted to the analysis of this heterogeneity...

Carbon fiber-reinforced plastic (CFRP) is widely used for structural members of transportation vehicles such as automobile, aircraft, or spacecraft, utilizing its excellent specific strength and specific rigidity in contrast with the metal. Short carbon fiber composite materials are receiving a lot of attentions because of their excellent moldability and productivity, however they show complicated behaviors in fatigue fracture due to the random fibers orientation. In this study, thermoelastic stress analysis (TSA) using an infrared thermography was applied to evaluate fatigue damage in short carbon fiber composites...

OBJECTIVE: Endothelial cells (ECs) play an important role in neovascularisation, but are too limited in number for adequate therapeutic applications. Mesenchymal stem cells (MSCs) have the potential to differentiate into endothelial lineage cells, which makes them attractive candidates for therapeutic angiogenesis. The aim of this study was to investigate efficient differentiation of MSCs into ECs by inducing medium in vitro. METHODS: MSCs were isolated from bone marrow by density gradient centrifugation...
