Introduction
Hand, foot and mouth disease (HFMD) is usually caused by several serotypes from human enterovirus A species, including enterovirus 71 (EV-A71) and coxsackievirus A16 (CV-A16). Two inactivated monovalent EV-A71 vaccines have been recently licensed in China and monovalent CV-A16 vaccine and bivalent EV-A71 and CV-A16 vaccine are under development. Methods: Using notifications from the national surveillance system, we describe the epidemiology and dynamics of HFMD in the country, before the introduction of EV-A71 vaccination, from 2008 through 2015. Results: Laboratory-identified serotype categories, i.e. CV-A16, EV-A71 and other enteroviruses, circulated annually. EV-A71 remained the most virulent serotype and was the major serotype for fatal cases (range: 88.5–95.4%) and severe cases (range: 50.7–82.3%) across years. Except for 2013 and 2015, when other enteroviruses were more frequently found in mild HFMD (48.8% and 52.5%), EV-A71 was more frequently detected from mild cases in the rest of the years covered by the study (range: 39.4–52.6%). The incidence rates and severity risks of HFMD associated with all serotype categories were the highest for children aged 1 year and younger, and decreased with increasing age. Discussion/conclusion: This study provides baseline epidemiology for evaluation of vaccine impact and potential serotype replacement.

Published: December 2017

Lupeol, a dietary triterpene, present in many fruits and medicinal plants, has been reported to possess many pharmacological properties including anti-cancer activities both in vitro.The present study is conducted to investigate the anticancer activity and the underlying mechanisms of Lupeol analogue (oxime) on human mammary cancer (MCF-7).MTT assay showed that the lupeol analogue had marked cytotoxic activity in MCF-7 cancer cells.We observed increased levels of Antioxidants (ABTS, DPPH,Superoxide anions radical scavenging activity,Hydroxyl radical scavenging activity) in MCF-7 cell line, because of anti oxidant mechanism of lupeol analogue (oxime) .We observed the higher concentrations ( 20,30,40,50 and 70 µM/mL) of lupeol analogue treatment significantly showed increased cytotoxicity in MCF-7 cells. The IC50 value was found to be 40 µM/mL of lupeol analogue (oxime) could greatly inhibit the cell growth. So, we have chosen at 40 and 320 µM/mL concentration of lupeol analogue (oxime) for further experiments. We observed increased levels of Lipid peroxidation and decreased levels of Antioxidants (SOD,CAT,GPx,GSH) in MCF-7 cell line because of the pro oxidant mechanism of lupeol analogue (oxime) . These observations revealed the cytotoxic potential of lupeol, which could be attributed to their prooxidant property on the MCF-7 cells. It is evident from the observation made in the present study that the lupeol analogue (oxime)has potential anticancer effect compared to Lupeol.
Theoretical investigations on temperature dependence of thermodynamic properties and concentration fluctuations of In-Tl binary liquid alloys by optimization method
Authors: Shrestha G K , Jha I S , Singh B K 
Published: December 2017

The thermodynamic properties, i.e. free energy of mixing (GM), heat of mixing (HM), entropy of mixing (SM) and activity (ai) of the component i (i , and structural property i.e. concentration fluctuations in long wave-length limit [Scc(0)] of In-Tl binary liquid alloy at a specified temperature have been investigated in the framework of quasi-lattice model on assuming the coupled effect of size ratio and entropic (or energetic) as well as enthalpic effect. These properties of In-Tl liquid alloy at 723 K have been computed theoretically by estimating the best fit value of order energy parameter (W) and size ratio () over the entire range of concentration in order to match their experimental values. The best fit value of W at 723 K has been used to determine the values of W at different temperatures with the help of temperature derivative of W which are then used for the optimization procedure in order to calculate the corresponding values of excess free energy of mixing, partial excess free energy of mixing and activity of the components involved in the alloy at different temperatures. These parameters have been used to investigate the concentration fluctuations in long wavelength limit {Scc(0)} of In-Tl binary liquid alloy at different temperatures over the entire range of concentration which have been used to predict the various other structural properties like excess stability function (EXS), diffusion coefficient ratio (Dm/Did), short range order parameter (α1) at different temperatures.BIBECHANA 15 (2018) 11-23

BACKGROUND: Research suggests that effect of continuous static stretching on sport performance and/or injury prevention depends on the total stretching volume. OBJECTIVE: To analyze the acute effects of three short duration static stretching interventions of four lower limb muscle groups (15, 30 and 60 seconds per muscle) on the eccentric isokinetic peak force (PF) and peak power (PP) measures obtained during leg press exercise. METHODS: A total of thirteen amateur athletes, 7 men and 6 women, completed four different interventions in a randomized order on separate days: one control (non-stretching) and three static stretching (SS) interventions (1 [Formula: see text] 15 s, 1 [Formula: see text] 30 s and 1 [Formula: see text] 60-s). After the stretching or control interventions, eccentric isokinetic PF and PP were assessed at two different linear velocities (200 mm/s and 400 mm/s). RESULTS: Measures were compared via a magnitude-based inference analysis. The results of this study showed no significant main effects between intervention-paired comparisons for any PF and PP measures. CONCLUSION: The findings of this study suggest that sport-relevant durations of SS have no effect on eccentric strength and power performance during leg press exercise and hence, the role of SS as a method to reduce the relative risk of injury is questionable.
Assessing the use of Radio Frequency Identification technologies as an alternative for insurance costs in hospitals
Authors: Asgharzadeh-Karamshahloo Iraj , Jabbarzadeh Armin , Shavvalpour Saeed 
Published: December 2017

OBJECTIVES: This research assesses the use of Radio Frequency Identification (RFID) technologies as an alternative for insurance costs in hospitals. METHODS: Despite the advantages of RFID, this technology has not been applied in most hospitals due to implementation costs and amortization of RFID. In this paper, we intend to model the total profit of hospitals in three scenarios namely, application of RFID technology in the hospital, without applying RFID technology in the hospital and insuring patients and equipment in the hospital. RESULTS: We analyzed the aforementioned situations over a period of time to find out how they affect the profit of the hospital. Based on this analysis we concluded that if applying RFID technology is costly, it will be feasible for advanced hospitals with more beds. In the scenario of insuring patients and equipment, if insurance organization takes over a small portion of the cost of the mistakes and oversights, insuring patients and equipment will not be feasible for the hospital, and it is better to apply RFID technology Instead. CONCLUSIONS: RFID is among the technologies applied to reduce mistakes of the personnel in hospitals. Moreover, applying this technology has led to a decrease in the number of personnel required in hospitals. This study models total profit of hospitals in three aforementioned scenarios. Based on analyzing these models we conclude that if applying RFID technology is costly, it will be feasible for advanced hospitals with more beds.
Viscous Overstability in Saturn’s Rings: Influence of Collective Self-gravity
Authors: Lehmann Marius , Schmidt Jürgen , Salo Heikki 
Published: December 2017

Abstract
We investigate the influence of collective self-gravity forces on the nonlinear, large-scale evolution of the viscous overstability in Saturn’s rings. We numerically solve the axisymmetric nonlinear hydrodynamic equations in the isothermal and non-isothermal approximation, including radial self-gravity and employing transport coefficients derived by Salo et al. We assume optical depths

to model Saturn’s dense rings. Furthermore, local N-body simulations, incorporating vertical and radial collective self-gravity, are performed. Vertical self-gravity is mimicked through an increased frequency of vertical oscillations, while radial self-gravity is approximated by solving the Poisson equation for an axisymmetric thin disk with a Fourier method. Direct particle–particle forces are omitted, which prevents small-scale gravitational instabilities (self-gravity wakes) from forming, an approximation that allows us to study long radial scales and to compare directly the hydrodynamic model and the N-body simulations. Our isothermal and non-isothermal hydrodynamic model results with vanishing self-gravity compare very well with results of Latter & Ogilvie and Rein & Latter, respectively. In contrast, for rings with radial self-gravity we find that the wavelengths of saturated overstable waves settle close to the frequency minimum of the nonlinear dispersion relation, i.e., close to a state of vanishing group velocities of the waves. Good agreement is found between non-isothermal hydrodynamics and N-body simulations for moderate and strong radial self-gravity, while the largest deviations occur for weak self-gravity. The resulting saturation wavelengths of viscous overstability for moderate and strong self-gravity (

) agree reasonably well with the length scales of axisymmetric periodic microstructure in Saturn’s inner A ring and the B ring, as found by Cassini.
A Sun-to-Earth Analysis of Magnetic Helicity of the 2013 March 17–18 Interplanetary Coronal Mass Ejection

Published: December 2017

Abstract
We compare the magnetic helicity in the 2013 March 17–18 interplanetary coronal mass ejection (ICME) flux rope at 1 au and in its solar counterpart. The progenitor coronal mass ejection (CME) erupted on 2013 March 15 from NOAA active region 11692 and is associated with an M1.1 flare. We derive the source region reconnection flux using the post-eruption arcade (PEA) method that uses the photospheric magnetogram and the area under the PEA. The geometrical properties of the near-Sun flux rope is obtained by forward-modeling of white-light CME observations. Combining the geometrical properties and the reconnection flux, we extract the magnetic properties of the CME flux rope. We derive the magnetic helicity of the flux rope using its magnetic and geometric properties obtained near the Sun and at 1 au. We use a constant-α force-free cylindrical flux rope model fit to the in situ observations in order to derive the magnetic and geometric information of the 1 au ICME. We find a good correspondence in both amplitude and sign of the helicity between the ICME and the CME, assuming a semi-circular (half torus) ICME flux rope with a length of π au. We find that about 83% of the total flux rope helicity at 1 au is injected by the magnetic reconnection in the low corona. We discuss the effect of assuming flux rope length in the derived value of the magnetic helicity. This study connecting the helicity of magnetic flux ropes through the Sun–Earth system has important implications for the origin of helicity in the interplanetary medium and the topology of ICME flux ropes at 1 au and hence their space weather consequences.
On the Impact Origin of Phobos and Deimos. II. True Polar Wander and Disk Evolution
Authors: Hyodo Ryuki , Rosenblatt Pascal , Genda Hidenori , Charnoz Sébastien 
Published: December 2017

Abstract
Phobos and Deimos are the two small Martian moons, orbiting almost on the equatorial plane of Mars. Recent works have shown that they can accrete within an impact-generated inner dense and outer light disk, and that the same impact potentially forms the Borealis basin, a large northern hemisphere basin on the current Mars. However, there is no a priori reason for the impact to take place close to the north pole (Borealis present location), nor to generate a debris disk in the equatorial plane of Mars (in which Phobos and Deimos orbit). In this paper, we investigate these remaining issues on the giant impact origin of the Martian moons. First, we show that the mass deficit created by the Borealis impact basin induces a global reorientation of the planet to realign its main moment of inertia with the rotation pole (True Polar Wander). This moves the location of the Borealis basin toward its current location. Next, using analytical arguments, we investigate the detailed dynamical evolution of the eccentric inclined disk from the equatorial plane of Mars that is formed by the Martian-moon-forming impact. We find that, as a result of precession of disk particles due to the Martian dynamical flattening J
2 term of its gravity field and particle–particle inelastic collisions, eccentricity and inclination are damped and an inner dense and outer light equatorial circular disk is eventually formed. Our results strengthen the giant impact origin of Phobos and Deimos that can finally be tested by a future sample return mission such as JAXA’s Martian Moons eXploration mission.
Variations between Dust and Gas in the Diffuse Interstellar Medium. III. Changes in Dust Properties
Authors: Reach William T. , Bernard Jean-Philippe , Jarrett Thomas H. , Heiles Carl 
Published: December 2017

Abstract
We study infrared emission of 17 isolated, diffuse clouds with masses of order

to test the hypothesis that grain property variations cause the apparently low gas-to-dust ratios that have been measured in those clouds. Maps of the clouds were constructed from Wide-field Infrared Survey Explorer (WISE) data and directly compared with the maps of dust optical depth from Planck. The mid-infrared emission per unit dust optical depth has a significant trend toward lower values at higher optical depths. The trend can be quantitatively explained by the extinction of starlight within the clouds. The relative amounts of polycyclic aromatic hydrocarbon and very small grains traced by WISE, compared with large grains tracked by Planck, are consistent with being constant. The temperature of the large grains significantly decreases for clouds with larger dust optical depth; this trend is partially due to dust property variations, but is primarily due to extinction of starlight. We updated the prediction for molecular hydrogen column density, taking into account variations in dust properties, and find it can explain the observed dust optical depth per unit gas column density. Thus, the low gas-to-dust ratios in the clouds are most likely due to “dark gas” that is molecular hydrogen.
