Abstract
Synthesis of imprinted ionic material SiO2(BGS/RHA)-TMPDT-Im-Au) was successfully studied. Sodium silicate from a mixture of ash bagasse and rice husk (Na2SiO3(BGS/RHA)) were used as the precursors. Furthermore, Na2SiO3(BGS/RHA is modified with the N
1-(3-Trimethoxysilylpropyl)diethylenetriamine (TMPDT) in which Au(III) ions are used as templates. The synthesis results were characterized by Fourier-transform infrared spectroscopy (FTIR), Surface area analyzers (SAA), Thermo Gravimetric analysis (TGA), Scanning Electron Microscope with Energy Dispersive X-ray Spectroscopy (SEM-EDX). The adsorption study was carried out using a batch system conducted in various pH and contact time. The adsorption process achieved a maximum pH of 3 in a 60-minute equilibrium time. Au(III) adsorption capacity of SiO2(BGS/RHA)-TMPDT-Im-Au was 10.44 mg/g. The kinetic studies show that the adsorption of Au(III) on SiO2(BGS/RHA)-TMPDT-Im-Au follows a pseudo-second-order with the reaction rate constant (k) of 76.7331 g mol–1 min–1.

Abstract
Coal is an alternative source of energy besides petroleum and natural gas which are widely used so they can produce a large amount of waste such as fly ash. Natural zeolite is a natural material that is widely spread in the territory of Indonesia. Fly ash and natural zeolite contain a SiO2 and Al2O3 that can be used as an adsorbent. This study aims to create a composite of fly ash/natural zeolite activated as adsorbent to optimize the performance of Pb heavy metal adsorption. Fly ash and natural zeolite were activated using NaOH 3M, and HCl 1M. The adsorption process was carried out with variations of composition 100:00, 75:25, 50:50, 25:75, 00:100 (w/w), variations in pH of 1, 2, 3, 4, 5, 6, and contact time variations 15, 30, 45, 60, 75, 90 min. The adsorbent characterization was performed with FTIR, XRD, SAA, and total specific acidity as well as the final measurement of Pb metal concentration determined by AAS spectrophotometer. The activation process can be shown on the FTIR spectra with the shift of wave numbers, XRD diffractogram showed the decrease of intensity in fly ash and natural zeolite, the increase of acidity value and surface area on each material shows the availability of more active groups. The adsorption of metal Pb reached the optimum condition on fly ash:natural zeolite composition 75:25 (w/w), pH condition of 5, and contact time 60 min, and adsorption capacity of 0, 577 mg/g and 97% adsorption percentage following Langmuir isotherm. The adsorption result obtained is supported by characterization of adsorbent after and before adsorption using SEM EDX indicating the presence of Pb element on adsorbent after adsorption and the surface morphology became rougher due to effect of Pb metal absorption.

Abstract
Natural zeolite is an unique crystal that has a very small and uniform pore size when compared to other adsorbents, such as activated carbon and silica gel. This study aims to determine the potential of natural zeolite as an adsorbent, to absorb toxic gases in pond water, especially shrimp ponds and to study its kinetics rate of NH4 and NO2 adsorption. This study consisted of two stages: activated zeolite using NaOH, and tested the absorption power of NH4 and NO2 gases. Zeolite was activated using NaOH where 25 grams of zeolite were mixed with 0.5N NaOH and heated for 2 hours at 70°C, then stirred and dried in an oven at 110°C for 4 hours. Then zeolite was cooled in a desiccator. The results of NH4 and NO2 gas adsorption showed that natural zeolites can reduce NH4 and NO2 gas levels in shrimp pond water. The rate constant of pseudo-second-order, and the initial adsorption rate at any given time t, can be predicted from the equation which is full zeolite obtained the best perform of NH4 and NO2 adsorption.

Detection of a common odd aberration in confocal reflection microscopy by means of an edge scan
Authors: Smid Pieter , See Chung W , Wright Amanda J 
Published: October 2019

Abstract
In reflection laser scanning microscopes, detection of odd aberrations is challenging because aberration cancellation can occur after the second passage of the light beam through the system. A method is proposed that uses a sample containing high spatial frequencies, such as an edge scan, to detect and measure the presence of odd aberrations. The new approach is demonstrated by scanning the focal spot over an edge in a confocal reflection microscope when coma is present in the imaging system (a common odd aberration). It is shown that the edge response displays characteristic distortions which are typical of coma. Detection of amplitude, sign and orientation of the coma aberration is made possible by comparison of the measured edge responses with theoretical curves.

Abstract

Background
few studies had investigated seasonal pattern of recurrent falls.

Objective
to examine seasonal pattern of both single and recurrent falls amongst community-dwelling older adults first applying for long-term care (LTC) services.

Methods
a cohort of 89,100 community-dwelling Hong Kong older adults aged 65 and over first applying for LTC services from 2005 to 2014 was obtained. Logistic regression models were used to examine seasonal pattern in single and recurrent falls, whilst controlling for gender, age and year.

Results
amongst 89,100 older adults, about 32% fell in past 90 days. Amongst the fallers, 34% fell recurrently. In 2014, the incidences of all fall, single fall and recurrent fall were 1.95, 0.80 and 1.15 per person-years, respectively. For single falls, the 90-day fall risk was highest during November to February with an odds ratio (OR) of 1.29 (95% confidence interval [CI] 1.19–1.41), compared with the lowest one during July to October. For recurrent falls, the highest OR for 90-day risk was highest during November to February (1.46, 95% CI 1.31–1.64) as well.

Conclusions
single and recurrent falls both peaked during winter months. Interventions, such as implementing educational publicity and sending reminder to older adults in fall season, may be considered.

AbstractMotivationHigh-throughput phenomic projects generate complex data from small treatment and large control groups that increase the power of the analyses but introduce variation over time. A method is needed to utlize a set of temporally local controls that maximizes analytic power while minimizing noise from unspecified environmental factors.ResultsHere we introduce ‘soft windowing’, a methodological approach that selects a window of time that includes the most appropriate controls for analysis. Using phenotype data from the International Mouse Phenotyping Consortium (IMPC), adaptive windows were applied such that control data collected proximally to mutants were assigned the maximal weight, while data collected earlier or later had less weight. We applied this method to IMPC data and compared the results with those obtained from a standard non-windowed approach. Validation was performed using a resampling approach in which we demonstrate a 10% reduction of false positives from 2.5 million analyses. We applied the method to our production analysis pipeline that establishes genotype–phenotype associations by comparing mutant versus control data. We report an increase of 30% in significant P-values, as well as linkage to 106 versus 99 disease models via phenotype overlap with the soft-windowed and non-windowed approaches, respectively, from a set of 2082 mutant mouse lines. Our method is generalizable and can benefit large-scale human phenomic projects such as the UK Biobank and the All of Us resources.Availability and implementationThe method is freely available in the R package SmoothWin, available on CRAN http://CRAN.R-project.org/package=SmoothWin.Supplementary informationSupplementary data are available at Bioinformatics online.
Investigating How Viewing Common Humanity Scenarios Impacts Compassion: A Novel Approach
Authors: Ling Debbie , Olver John , Petrakis Melissa 
Published: October 2019

Abstract
Compassion is a core value in healthcare. It enables healthcare workers to respond with care and kindness to all patients. The perception of common humanity (CH) has been proposed as the central mechanism of compassion. There have been no empirical studies examining the connection between CH and compassion. The present study aimed to investigate the impact of viewing CH scenarios on compassion. Seventy-five healthcare workers participated and were randomly allocated to two groups. The healthcare workers viewed different CH scenarios and completed pre- and post-test validated scales on perspective-taking, CH and compassion. The authors investigated whether compassion increased after viewing the CH scenarios. A mediation analysis was performed to examine if perspective-taking influences compassion, mediated by CH. Some new CH items were also trialled to help develop a CH scale. The results demonstrated that healthcare workers’ level of compassion increased after viewing the CH scenarios. There was some evidence that perspective-taking influences compassion mediated by CH. CH appears to be a collection of constructs captured by a number of subscales. This study has important implications for supporting healthcare workers to develop and sustain compassion.

Published: October 2019

Abstract
Beyond disruption of neuronal pathways, focal stroke lesions induce structural disintegration of distant, yet connected brain regions via retrograde neuronal degeneration. Stroke lesions alter functional brain connectivity and topology in large-scale brain networks. These changes are associated with the degree of clinical impairment and recovery. In contrast, changes of large scale, structural brain networks after stroke are less well reported. We therefore aimed to analyse the impact of focal lesions on the structural connectome after stroke based on data from diffusion-weighted imaging and probabilistic fibre tracking. In total, 17 patients (mean age 64.5 ± 8.4 years) with upper limb motor deficits in the chronic stage after stroke and 21 healthy participants (mean age 64.9 ± 10.3 years) were included. Clinical deficits were evaluated by grip strength and the upper extremity Fugl-Meyer assessment. We calculated global and local graph theoretical measures to characterize topological changes in the structural connectome. Results from our analysis demonstrated significant alterations of network topology in both ipsi- and contralesional, primarily unaffected, hemispheres after stroke. Global efficiency was significantly lower in stroke connectomes as an indicator of overall reduced capacity for information transfer between distant brain areas. Furthermore, topology of structural connectomes was shifted toward a higher degree of segregation as indicated by significantly higher values of global clustering and modularity. On a level of local network parameters, these effects were most pronounced in a subnetwork of cortico-subcortical brain regions involved in motor control. Structural changes were not significantly associated with clinical measures. We propose that the observed network changes in our patients are best explained by the disruption of inter- and intrahemispheric, long white matter fibre tracts connecting distant brain regions. Our results add novel insights on topological changes of structural large-scale brain networks in the ipsi- and contralesional hemisphere after stroke.

Abstract
Huntington’s disease (HD) is a neurodegenerative disorder characterized by involuntary movements, cognitive deficits, and psychiatric disturbances. Although evidence indicates that projections from motor cortical areas play a key role in the development of dysfunctional striatal activity and motor phenotype, little is known about the changes in cortical microcircuits and their role in the development of the HD phenotype. Here we used two-photon laser-scanning microscopy to evaluate network dynamics of motor cortical neurons in layers II/III in behaving transgenic R6/2 and knock-in Q175+/− mice. Symptomatic R6/2 mice displayed increased motion manifested by a significantly greater number of motion epochs, whereas symptomatic Q175 mice displayed decreased motion. In both models, calcium transients in symptomatic mice displayed reduced amplitude, suggesting decreased bursting activity. Changes in frequency were genotype- and time-dependent; for R6/2 mice, the frequency was reduced during both motion and nonmotion, whereas in symptomatic Q175 mice, the reduction only occurred during nonmotion. In presymptomatic Q175 mice, frequency was increased during both behavioral states. Interneuronal correlation coefficients were generally decreased in both models, suggesting disrupted interneuronal communication in HD cerebral cortex. These results indicate similar and contrasting effects of the HD mutation on cortical ensemble activity depending on mouse model and disease stage.
