Proteomic Insights into Endometrial Receptivity and Embryo‐Endometrial Epithelium Interaction for Implantation Reveal Critical Determinants of Fertility
Authors: Evans Jemma , Hutchison Jennifer , Salamonsen Lois A. , Greening David W. 
Published: December 2019

AbstractIn vitro fertilization has overcome infertility issues for many couples. However, achieving implantation of a viable embryo into the maternal endometrium remains a limiting step in optimizing pregnancy success. The molecular mechanisms which characterize the transient state of endometrial receptivity, critical in enabling embryo‐endometrial interactions, and proteins which underpin adhesion at the implantation interface, are limited in humans despite these temporally regulated processes fundamental to life. Hence, failure of implantation remains the “final frontier” in infertility. A human coculture model is utilized utilizing spheroids of a trophectoderm (trophoblast stem) cell line, derived from pre‐implantation human embryos, and primary human endometrial epithelial cells, to functionally identify “fertile” versus “infertile” endometrial epithelium based on adhesion between these cell types. Quantitative proteomics identified proteins associated with human endometrial epithelial receptivity (“epithelial receptome”) and trophectoderm adhesion (“adhesome”). As validation, key “epithelial receptome” proteins (MAGT‐1/CDA/LGMN/KYNU/PC4) localized to the epithelium of receptive phase (mid‐secretory) endometrium obtained from fertile, normally cycling women but is largely absent from non‐receptive (proliferative) phase tissues. Factors involved in embryo‐epithelium interaction in successive temporal stages of endometrial receptivity and implantation are demonstrated and potential targets for improving fertility are provided, enhancing potential to become pregnant either naturally or in a clinical setting.

AbstractBackgroundIncreasingly complex genetics counseling requires guidance to facilitate counselees' psychosocial adjustment. We explored networks of inter‐relationships among coping strategies and specific psychosocial difficulties in women tested for hereditary breast or ovarian cancer.MethodsOf 752 counselees consecutively approached, 646 (86%) completed questionnaires addressing coping strategies (Brief‐COPE) and psychosocial difficulties (PAHC) after the initial genetic consultation (T1), and 460 (61%) of them again after the test result (T2). We applied network analysis comparing partial correlations among these questionnaire scales, according to the type of genetic test ‐ single gene‐targeted or multigene panel, test result and, before and after testing.ResultsOverall, 98 (21.3%), 259 (56.3%), 59 (12.8%) and 44 (9.6%) women received a pathogenic variant, uninformative negative (panel testing), variant of uncertain significance (VUS) or true negative (targeted testing) result, respectively. In most networks, connections were strongest between avoidance and general negative emotions. Cognitive restructuring was inter‐related to lower psychosocial difficulties. Avoidance and familial/social relationship difficulties were strongly related in women receiving a pathogenic variant. Stronger inter‐relationships were also noticed between avoidance and worries about personal cancer and concerns about hereditary predisposition in women receiving a VUS result. Differences in the prominence of inter‐relationships were observed by type of testing and assessment time.ConclusionsNetwork analysis may be fruitful to highlight prominent inter‐relationships among coping strategies and psychosocial difficulties, in women tested for HBOC susceptibility, offering guidance for counseling.

Published: December 2019

AbstractThe functionalisation of 2‐naphthols and their derivatives has much importance because of their potential pharmaceutical and materials applications. In this context, this work presents a fast, cheap, and efficient method for direct chalcogenylation at position C1 of 2‐naphthols promoted by simple bases. The mechanistic studies indicate an ionic mechanism, essentially an electrophilic aromatic substitution, with a key role played by atmospheric oxygen for regeneration of the diorganoyl dichalcogenides.
Extraction of Luteolin from Peanut Shells by A Hydrophilic Ionic Liquid‐based Microwave‐assisted Method

Published: December 2019

AbstractAn ionic liquid‐based microwave‐assisted extraction method was developed to extract luteolin from peanut shells effectively. A series of hydrophilic 1‐alkyl‐3‐methylimidazolium ionic liquids with different anions (Br−, Cl− and BF4−) and different cations ([C2mim]+, [C4mim]+, [C8mim]+ and [C10mim]+) were screened, and [C10mim]Br was found to be the optimal extraction solvent. The reason is that when the cations are the same, the hydrogen bonding between Br− and the phenolic hydroxyl group on luteolin is the strongest; when the anions are the same, the carbon chain growth enhances the van der Waals force between the ionic liquid and the luteolin. The concentration of ionic liquid, extraction temperature, liquid‐solid ratio and extraction time were optimized by both single factor experiments and response surface methodology. Under the optimized conditions of [C10mim]Br concentration 1.00 mol/L, extraction temperature 85 °C, liquid‐solid ratio 11.63:1 mL/g, extraction time 12 min, the extraction yield of luteolin reached 80.36±0.67%. In addition, compared with conventional solvents, [C10mim]Br showed an excellent extraction yield to extracting luteolin from peanut shells .
Transparent Conductive Layer Based on Oriented Platinum Networks
Authors: Nizameev Irek , Nizameeva Guliya , Kadirov Marsil 
Published: December 2019

AbstractThe paper proposes an original method of creating a transparent electrically conductive coating based on oriented networks of platinum nanowires. Platinum nanowires are obtained by chemical precipitation from the liquid phase using the micellar template of cetyltrimethylammonium bromide (CTAB) as a form‐creating and orienting component. The deposition of networks is made on the glass, using a small amount of platinum. Platinum nanowires with a height of 3–6 nm have a width of 50–60 nm, which corresponds in shape to a tape or a strip. The ratio of the length of the stripes to the width is about 500: 1. The aspect ratio of length to width is about 500:1. The orientation of the bands is high, and the density on the glass surface is low. This fact contributes to obtaining high optical transparency of the layer with a small value of the surface resistance of the coating.

Published: December 2019

AbstractLayered MoS2 is a prospective candidate for use in energy harvesting, valleytronics, and nanoelectronics. Its properties strongly related to its stacking configuration and the number of layers. Due to its atomically thin nature, understanding the atomic‐level and structural modifications of 2D transition metal dichalcogenides is still underdeveloped, particularly the spatial control and selective precision. Therefore, the development of nanofabrication techniques is essential. Here, an atomic‐scale approach used to sculpt 2D few‐layer MoS2 into lateral heterojunctions via in situ scanning/transmission electron microscopy (STEM/TEM) is developed. The dynamic evolution is tracked using ultrafast and high‐resolution filming equipment. The assembly behaviors inherent to few‐layer 2D‐materials are observed during the process and included the following: scrolling, folding, etching, and restructuring. Atomic resolution STEM is employed to identify the layer variation and stacking sequence for this new 2D‐architecture. Subsequent energy‐dispersive X‐ray spectroscopy and electron energy loss spectroscopy analyses are performed to corroborate the elemental distribution. This sculpting technique that is established allows for the formation of sub‐10 nm features, produces diverse nanostructures, and preserves the crystallinity of the material. The lateral heterointerfaces created in this study also pave the way for the design of quantum‐relevant geometries, flexible optoelectronics, and energy storage devices.
Amorphous Catalysts and Electrochemical Water Splitting: An Untold Story of Harmony
Authors: Anantharaj Sengeni , Noda Suguru 
Published: December 2019

AbstractIn the near future, sustainable energy conversion and storage will largely depend on the electrochemical splitting of water into hydrogen and oxygen. Perceiving this, countless research works focussing on the fundamentals of electrocatalysis of water splitting and on performance improvements are being reported everyday around the globe. Electrocatalysts of high activity, selectivity, and stability are anticipated as they directly determine energy‐ and cost efficiency of water electrolyzers. Amorphous electrocatalysts with several advantages over crystalline counterparts are found to perform better in electrocatalytic water splitting. There are plenty of studies witnessing performance enhancements in electrocatalysis of water splitting while employing amorphous materials as catalysts. The harmony between the flexibility of amorphous electrocatalysts and electrocatalysis of water splitting (both the oxygen evolution reaction [OER] and the hydrogen evolution reaction [HER]) is one of the untold and unsummarized stories in the field of electrocatalytic water splitting. This Review is devoted to comprehensively discussing the upsurge of amorphous electrocatalysts in electrochemical water splitting. In addition to that, the basics of electrocatalysis of water splitting are also elaborately introduced and the characteristics of a good electrocatalyst for OER and HER are discussed.
In Situ Monitoring Small Energy Storage Change of Electrochromic Supercapacitors via Perovskite Photodetectors

Published: December 2019

AbstractIn situ monitoring the healthy state of energy storage devices is a smart way to avoid severe accidents and major emergencies. Electrochromic supercapacitors (ECSCs) stand out among other devices owing to the smart color variation during charge and discharge processes. However, it is hard to obtain the precise state of charge via only identifying their color change. To address this problem, an integral system composed of the inorganic CsPbBr3 perovskite photodetector (PPD) and polyaniline (PANI)//WO3 ECSC is proposed here. The PPD can simultaneously collect the variation of responsive current (under a green laser with the wavelength of 520 nm) when the ECSC is being charged or discharged. The real‐time state of charge following the color change can be recorded by the PPDs constantly and accurately. A voltage alteration as small as 47.2 mV (charge variation of 0.33 mC) can be detected by this integral system rapidly, implying its great potential in managing the health condition of ECSC or even common energy storage devices in the future.

Authors: Poli G. L. , Torres L. , Coca M. , Veselinovic M. , Lassmann M. , Delis H. , Fahey F. 
Published: December 2019

Abstract
Purpose
The International Atomic Energy Agency (IAEA) decided to initiate a survey to evaluate the current status of the practice of paediatric nuclear medicine worldwide, with the focus mainly on low and middle-income countries specifically in Latin America, Eastern Europe, Africa and Asia. This investigation sought to determine if the practice in paediatric nuclear medicine in these countries differed from that indicated by the survey of the Nuclear Medicine Global Initiative (NMGI) and if nuclear medicine practitioners were following established paediatric nuclear medicine guidelines.

Methods
A total of 133 institutes took part in the survey from 62 different IAEA member states within Africa (29), Asia (39), Europe (29) and Latin America (36). The four most frequent conventional (single-photon) nuclear medicine procedures were 99mTc labelled MDP, DSMA, MAG3 and pertechnetate thyroid scans. In addition, 46 centres provided data on FDG PET/CT, including exposure data for the CT component. Nearly half of the sites (48%) perform less than 200 paediatric nuclear medicine studies per year, while 11% perform more than 1000 such studies per year.

Results
Administered activities largely exceeded the recommendations for most of the sites for DMSA, MAG3 and pertechnetate, while compliance with international standards was somehow better for MDP studies. For FDG PET, the results were more uniform than for conventional nuclear medicine procedures. However, the use of CT in PET/CT for paediatric nuclear medicine revealed a high variability and, in some cases, high, dose-length product (DLP) values. This observation indicates that further attention is warranted for optimizing clinical practice in FDG PET/CT.

Conclusions
Overall, in most parts of the world, efforts have been undertaken to comply either with the EANM dosage card or with the North American Consensus Guidelines. However, variability in the practice of paediatric nuclear medicine still exists. The results of this survey provide valuable recommendations for a path towards global standardization of determining the amount of activity to be administered to children undergoing nuclear medicine procedures.
Opposites Attract: Assortative Mating and Immigrant–Native Intermarriage in Contemporary Sweden
Authors: Elwert Annika 
Published: December 2019

AbstractThis paper studies how immigrant–native intermarriages in Sweden are associated with individual characteristics of native men and women and patterns of assortative mating. Patterns of educational- and age-assortative mating that are similar to those found in native–native marriages may reflect openness to immigrant groups, whereas assortative mating patterns that indicate status considerations suggest that country of birth continues to serve as a boundary in the native marriage market. The study uses Swedish register data that cover the entire Swedish population for the period of 1991–2009. The results from binomial and multinomial logistic regressions show that low status of natives in terms of economic and demographic characteristics is associated with intermarriage and that intermarriages are characterized by educational and age heterogamy more than are native–native marriages. The findings indicate that immigrant women as well as immigrant men become more attractive marriage partners if they are considerably younger than their native spouses. This is particularly true for intermarriages with immigrants from certain regions of origin, such as wives from Asia and Africa and husbands from Asia, Africa, and the Middle East. Gender differences in the intermarriage patterns of native men and women are surprisingly small.
Can Cartoons Which Depict Autistic Characters Improve Attitudes Towards Autistic Peers?
Authors: Engel Carla Simone , Sheppard Elizabeth 
Published: December 2019

AbstractThis study aimed to assess the efficacy of two cartoons which depict autistic characters in improving attitudes towards autistic peers in two separate studies. Forty-six children participated in study 1 (4–7 years), and 47 children participated in study 2 (8–11 years). Both the conative (behavioural) component of attitudes and knowledge about autism were measured before and after the cartoon interventions. Knowledge of autism increased after watching the cartoons in both studies but attitudes to autism only improved in study 1. Knowledge was shown to correlate with change in some but not all attitude measures. The findings suggest that cartoons can improve attitudes to autism, but this may depend on how information is presented.

Abstract
Purpose
We developed and applied a universal strategy for preimplantation genetic testing for all cystic fibrosis gene mutations (PGT-CF) based on next-generation sequencing (NGS).

Methods
A molecular protocol was designed to diagnose all CF mutations at preimplantation stage. The detection of CF mutations was performed by direct gene sequencing and linkage strategy testing 38 specific SNPs located upstream and inside the gene for PGT-CF. Seventeen couples at risk of CF transmission decided to undergo PGT-CF. Trophectoderm cell biopsies were performed on day 5–6 blastocysts. PGT for aneuploidy (PGT-A) was performed from the same samples. Tested embryos were transferred on further natural cycles.

Results
PGT was performed on 109 embryos. Fifteen CF mutations were tested. PGT-CF and PGT-A were conclusive for respectively 92.7% and 95.3% of the samples. A mean of 24.1 SNPs was informative per couple. After a single embryo transfer on natural cycle, 81.3% of the transferred tested embryos were implanted.

Conclusions
The present protocol based on the entire CFTR gene together with informative SNPs outside and inside the gene can be applied to diagnose all CF mutations at preimplantation stage.

Recovery of ammonia from wastewater through chemical precipitation
Authors: Bianchi Lavinia , Kirwan Kerry , Alibardi Luca , Pidou Marc , Coles Stuart R. 
Published: December 2019

AbstractChemical precipitation is a consolidated technique applied in wastewater treatment to remove and recover phosphorous and ammonium that remain in the effluent after the anaerobic digestion treatment. The precipitate is magnesium ammonium phosphate hexahydrate (MgNH4PO4·6H2O), also known as struvite, and it is sold as a slow-release fertiliser. However, the value of struvite is quite low and has a limited market. Furthermore, it precipitates with heavy metals and other impurities that need to be removed to make the fertiliser commercially viable. This study looked at the thermal decomposition of struvite to recover added value products and recycle the magnesium for further precipitation. A kinetic study was carried out to understand the mechanism of decomposition and the formation of the different solid phases, which is fundamental for the design and optimisation of the technology. The thermogravimetric study confirmed that thermal decomposition is possible, but ammonia could not be completely released below 250 °C. The thermal analysis also led to the determination of the energy required for the decomposition, found to be 1.87 kJ g−1, which also includes the evaporation of water and ammonia. The kinetic study through the isoconversional method showed the presence of two major reactions, and the model-fitting approach identified the diffusion model as the best fit for the first reaction. The activation energy of the first reaction found with this method was 0.24 kJ g−1, comparable with the data obtained from the isoconversional method. The two-stage decomposition reactions were proposed, and the final calcination product was confirmed as magnesium pyrophosphate, which could be used in agriculture or dissolved in diluted mineral acids solution to separate the phosphate from the magnesium.

Authors: Bamidele O. , Sonaiya E. B. , Adebambo O. A. , Dessie T. 
Published: December 2019

Abstract
Background
Availability of appropriate genetics is important for the development of smallholder poultry (SHP). The biological potential of improved dual purpose chicken germplasms was evaluated in Nigeria.

Methods
A total of six breeds (Fulani, FUNAAB Alpha, Kuroiler, Noiler, Sasso, and Shika-Brown) were tested on-station, in deep litter houses at two test centres (Public and private facility) for 504 days. Birds were fed ad libitum for the first 140 days after which restricted feeding was practised.

Result
Lowest and highest hatchability of eggs set was 55% (FUNAAB Alpha) and 89% (Sasso), respectively. At 140 days, male live weights were 200%–300 % higher than the local chickens (975 g) except Shika-Brown (152%) and Fulani (135%). Lowest (p < 0.05) age at first egg was 119 days for Shika-Brown and 120 days for FUNAAB Alpha and Kuroiler. Highest hen-housed egg production was 192 for Shika-Brown, and feed intake per dozen eggs was lowest (p < 0.05) for Shika-Brown (2.9 kg) and FUNAAB Alpha (2.9 kg). Mortality rate of the locally sourced breeds (Fulani, FUNAAB Alpha, Noiler, and Shika-Brown) was significantly lower (p < 0.05) than the foreign-sourced breeds (Kuroiler, Sasso) during brooding, growing and laying.

Conclusion
Results from this study identified FUNAAB Alpha and Noiler as being more suitable for dual-purpose functions (egg and meat), while Sasso and Kuroiler (meat) and Shika-Brown (egg) were observed to be better suited for single purpose functions. These findings could guide the introduction of smallholder poultry-specific hybrid germplasms for the development of the smallholder poultry production systems in Nigeria.
Understanding high-emitting households in the UK through a cluster analysis
Authors: Wang Xinfang , Meng Ming 
Published: December 2019

AbstractAnthropogenic climate change is a global problem that affects every country and each individual. It is largely caused by human beings emitting greenhouse gases into the atmosphere. In general, a small percentage of the population is responsible for a large amount of emissions. This paper focuses on high emitters and their CO2 emissions from energy use in UK homes. It applies a cluster approach, aiming to identify whether the high emitters comprise clusters where households in each cluster share similar characteristics but are different from the others. The data are mainly based on the Living Cost and Food survey in the UK. The results show that after equivalising both household emissions and income, the high emitters can be clustered into six groups which share similar characteristics within each group, but are different from the others in terms of income, age, household composition, category and size of the dwelling, and tenure type. The clustering results indicate that various combinations of socioeconomic factors, such as low-income single female living in an at least six-room property, or high-income retired couple owning a large detached house, could all lead to high CO2 emissions from energy use at home. Policymakers should target each high-emitter cluster differently to reduce CO2 emissions from energy consumption at home more effectively.
