Core Ideas
This study examined a new way to mitigate the effects of HTS on spring maize.
B2 had similar effects to ABA on alleviating maize yield penalty caused by HTS.
B2 reduced plant height and ear height.
Adopting spring maize (Zea mays L.) to replace part of a winter wheat (Triticum aestivum L.)–summer maize rotation system can mitigate agricultural water scarcity in the North China Plain. The main obstacle to increasing spring maize production is high‐temperature stress (HTS) at grain‐filling stage. In this study, a novel plant growth regulator (2,4‐dichloroformamide cyclopropane acid [B2]), based on the structures of abscisic acid (ABA), pyrabactin, and coronatine, was used to reduce maize yield penalty imposed by HTS. Field experiments were conducted to investigate the effects of B2 on alleviating maize yield penalty caused by HTS in 2015 and 2016. The hybrid maize cultivar Zhengdan958, which is widely planted across China, was grown at a density of 67,500 plants ha−1. Water, B2, and ABA were applied to maize foliar surfaces at the ninth‐expanded‐leaf stage. Application of B2 significantly increased grain yield by 8.5% by increasing thousand‐kernel weight and decreasing bare tip length compared with the control. Additionally, B2 significantly increased the SPAD value and ABA content of the ear leaf, enhancing net photosynthesis rate and heat resistance. Application of B2 also improved grain‐filling rate, grain volume, and grain dry weight, which contributed to higher grain yield. Moreover, B2 decreased plant and ear height, neither of which was affected by ABA. These results indicate that B2, with a biological activity similar that of ABA, could help maintain relatively higher photosynthetic capacity, heat resistance, and grain‐filling rate during the grain‐filling stage under HTS, providing a stable method to increase grain yield.
Clinical presentations of hypertrophic cardiomyopathy and implications for therapy
Authors: Díez-López Carles , Salazar-Mendiguchía Joel 
Published: October 2018

[first paragraph of article]Hypertrophic cardiomyopathy (HCM) is diagnosed in the presence of left ventricular hypertrophy of ≥15 mm in adult index cases, or ≥13 mm in relatives of known affected patients, that is not solely explained by abnormal loading conditions. In children, the left ventricle (LV) wall thickness should be more than two standard deviations above the predicted population mean. The typical anatomo-pathological findings include myocyte hypertrophy, disarray, interstitial fibrosis and small-vessel disease. Although all the myocytes are supposed to be affected, pathological alterations are not uniformly distributed throughout the myocardium. Asymmetrical hypertrophy of the interventricular septum is the most commonly observed phenotype, but any pattern of hypertrophy is consistent with the diagnosis.
Cardiac pacing in patients with hypertrophic obstructive cardiomyopathy
Authors: Tolosana José Maria , Trucco Emilce 
Published: October 2018

[first paragraph of article]About one-third of patients with hypertrophic cardiomyopathy (HCM) have resting left ventricular outflow tract obstruction (LVOTO). The presence of LVOTO in HCM facilitates the progression of heart failure and increases the risk of death. LVOTO is defined as a peak instantaneous Doppler LV outflow tract gradient ≥30 mmHg, but the threshold for invasive treatment is usually considered to be ≥50 mm Hg.
Prediction vs. estimation of dewpoint temperature: assessing GEP, MARS and RF models
Authors: Shiri Jalal 
Published: October 2018

AbstractDewpoint temperature (Tdew) plays a key role in agricultural issues as well as meteorological studies. This paper is aimed at developing and validating prediction and estimation models of Tdew values. Gene expression programming (GEP), multivariate adaptive regression spline (MARS), and random forest (RF) models were employed. Data from six weather stations (consisting of a period of ten years) in East Azerbaijan, northwestern Iran were utilized for establishing, testing, and validating the models. In the case of predicting models, chronological records of Tdew in previous time steps were introduced as models' inputs to predict Tdew values at daily and weekly prediction intervals. In the case of Tdew estimating models, daily records of mean air temperature, sunshine hours, relative humidity, and wind speed were utilized as inputs to estimate Tdew. Acquired results showed prediction-based GEP surpasses the MARS and RF models in both daily and weekly prediction intervals. Among the estimation models, the MARS models that relied on air temperature, relative humidity, and sunshine hours presented the most accurate results in all studied locations as well as the studied region. The current study proposes the use of MARS models in estimating Tdew magnitudes, while it criticizes the use of single data set assignment for both temporal and spatial analysis.
Bioassays and coagulation studies using Moringa oleifera seeds for the removal of textile dyes
Authors: Pecora Hengli Barbosa , Dilarri Guilherme , Mendes Carolina Rosai , Corso Carlos Renato 
Published: October 2018

Abstract
The aim of this work was to evaluate the removal of three different textile dyes through the coagulation action of the powder and supernatant of Moringa oleifera seeds. The pH of the solution and mass concentrations of the adsorbent were varied. Fourier transform infrared (FT-IR) spectrophotometry was used to evaluate the main interaction sites of the M. oleifera coagulants with the dyes. Bioassays were also conducted with Lactuca sativa and Eruca sativa seeds to evaluate the toxicity of the M. oleifera coagulants and dyes. Each dye interacted differently with the M. oleifera powder and supernatant; however, dye removal rates were higher than 70% even when varying the pH of the solution. FT-IR spectrophotometry revealed that the linkage of the dyes with the M. oleifera coagulants occurs through chemical interactions, and the coagulating protein of M. oleifera was confirmed as the removing agent. Depending on the dye molecule, the pH of the solution also exerted a strong influence on coagulation. The phytotoxicity tests showed that the coagulants in the seeds of M. oleifera are more toxic than the dyes tested. In conclusion, although efficient and economically feasible, the application of M. oleifera coagulants requires further investigation, especially with regard to ecotoxicology.
Operational modifications for the development of nitrifying bacteria in a large-scale biological aerated filter and its impact on wastewater treatment
Authors: Bourgeois François-René , Monette Frédéric , Cyr Daniel G. 
Published: October 2018

Abstract
To develop a better understanding for fixed biomass processes, the development of a nitrifying bacterial biofilm, as well as the performance of treatment during modifications to operational conditions of a full-scale submerged biological filter were examined. The development of the nitrifying biofilm was investigated at four depth levels (1, 2, 4 and 5 feet). The result of bacterial subpopulations analyzed by qPCR relative to the physico-chemical parameters of the wastewater during the various tests (sustained aeration, modified backwash parameters and inflow restriction) revealed an increase of the relative presence of nitrifying microorganisms throughout the biofilm (especially for nitrite oxidizing bacteria (NOB)), but this was not necessarily accompanied by a better nitrification rate. The highest observed nitrification rate was 49% of removal in the test cell during backwashing conditions, whereas the relative ammonia oxidizing bacteria (AOB) population was 0.032% and NOB was 0.008% of the total biomass collected. The highest percentage of nitrifying bacteria observed (0.034% AOB and 0.18% NOB) resulted in a nitrification rate of 21%. The treatment of organic matter determined by measuring the chemical and biochemical oxygen demand (COD, CBOD5) was improved.
A New Portable Colorimetric Sensor Based on RGB Chromaticity for Quantitative Determination of Sarin in Water
Authors: Huang Tingting , Liu Guohong , Yu Jingxiang , Liu Meng , Huang Zhiping , Li Jian , Li Danping 
Published: October 2018

Background:
Sarin is a nerve agent which is lethal to people due to its high toxicity. According
to its extreme toxicity, sarin, relatively lack of color, highly toxic, miscible in water, poses
viable threats to potable water sources. Therefore, there is an urgent need for portable, rapid and yet
reliable methods to monitor for adulteration of potable water sources by sarin on spot.

Methods:
A stock solution of 30 mg/L sarin was prepared daily by dissolving 300 μg of sarin in
10 mL isopropanol. A certain amount of sarin was added to the glass tube, and then o-dianisidine and
hydrogen peroxide were added. The pH value of the solution was adjusted to 9.8. The solution was
transferred to the test tube after 10 minutes. A test tube of 2 mL was placed between the light source
and the RGB color sensor. The LED light source illuminates directly over the test tube while the
RGB sensor obtained the generated spectral response. This RGB voltage output is connected to the
ADC and microcontroller to convert these analog voltages to three digital data. This RGB digital data
is linked to the microcomputer through the serial port that is interfaced with the user interface. The
data thus obtained in the sensor can be processed to display the sarin concentration.

Results:
Under the optimum conditions as described above, the calibration curve of chromaticity
value versus sarin concentration was linear in the range of 0.15 mg/L to 7.8 mg/L. According to the
IUPAC definition, theoretical detection limits of this method were 0.147 mg/L and 0.140 mg/L for R
and B values, respectively. The practical detection limit was 0.15 mg/L. The sensor was successfully
applied to the determination of sarin in artificial water samples and the recoveries were between
86.0% to 95.9%.

Conclusion:
The results in the present work have demonstrated the feasibility to design a new portable
colorimetric sensor based on the RGB chromaticity method for quantitative determination of sarin
in water. The influences of chromogenic reagent, oxidant, reaction time, o-dianisidine concentration,
hydrogen peroxide concentration, reaction temperature, pH on the chromaticity values were investigated.
The results showed that the sensor possessed high selectivity, sensitivity and good repeatability.
The method would be potentially applied to the analysis of other toxic compounds in
environment, such as other chemical warfare agents.
The Epithelial Barrier Model Shows That the Properties of VSL#3 Depend from Where it is Manufactured
Authors: Palumbo Paola , Lombardi Francesca , Cifone Maria Grazia , Cinque Benedetta 
Published: October 2018

Background:
VSL#3 has been extensively investigated and is currently recommended for
the prevention and treatment of chronic pouchitis and ulcerative colitis. Nonetheless, in vitro and in
vivo studies have recently shown variability in the VSL#3 efficacy often attributed to the manufacturing
process.

Objective:
The aim was to comparatively study the in vitro effects of two VSL#3 preparations produced
in different sites (named US- and Italy-made VSL#3) on CaCo-2 epithelial barrier model in
terms of trans-epithelial electrical resistance (TEER), dextran flux and expression of Tight Junctions
(TJ) proteins i.e. zonulin-1 (ZO-1) and occludin, in the absence or presence of a heat stress-related
damage of monolayer.

Methods:
TEER was evaluated on CaCo-2 differentiated monolayers. Epithelial permeability of polarized
monolayers was assessed by measuring the FITC-labeled dextran flux from the apical to basolateral
chambers. ZO-1/occludin levels were analyzed by western blot analysis. A set of experiments
was performed to compare the effects of both VSL#3 on TEER values, dextran flux and ZO-1/occludin
expression in CaCo-2 monolayers after heat stress exposure.

Results:
US- and Italy-made VSL#3 have opposing effects on TEER values, dextran flux, and ZO-
1/occludin expression, being all these parameters negatively influenced just by Italy-made product.
US-made probiotic did not affect baseline TEER, dextran flux and ZO-1 expression and strongly increased
occludin levels. Of note, pre-treatment of monolayer with US-made VSL#3, but not Italy-made
product, totally prevented the heat-induced epithelial barrier integrity loss.

Conclusion:
Our data trigger the need for reassessing efficacy or safety of the Italy-made VSL#3 considering
intestinal epithelial barrier plays an important role in maintaining host health.

Published: October 2018

Background:
Reinforced concrete silos and bunkers are commonly used structures for large storage of different materials. These structures are highly vulnerable when subjected to intense seismic forces. Available guidelines for analysis and design of these structures require special design skills and code procedures.

Objective:
The current study is aimed to elaborate the design procedures from different sources to a unified method, which can be applied to a larger class of reinforced concrete silos. In this study, analysis and design procedures are summarized and presented in a simplified form to make sure the efficient practical design applications of reinforced concrete silos.

Method:
Four different cases of silo design based on the type and weight of stored material were considered for the study. For each case, the silo was designed using given design procedure and modeled using FEM-based computer package. All of the reinforced concrete silos were subjected to gravity, wind and seismic forces.

Results:
After performing the analysis and design of different silos, the bending moment, shear force and axial forces profiles were given for a sample silo. The results obtained from the proposed design procedure were compared with FEM values for different components of silos such as slab, wall and hopper.

Conclusion:
The comparison of tangential and longitudinal forces, bending moments, shear forces and reinforcement ratios of different parts of silos have shown a fair agreement with the FEM model results. It motivates to use the proposed design procedure for an efficient design of reinforced concrete silos.
