Abstract
Based on first principle calculations, Ga rich and As(P) rich clean GaAs0.5P0.5(001) reconstruction surfaces and adsorbed surfaces with 0.125ML coverage of Cs at different sites are researched. Formation energy of Ga rich GaAs0.5P0.5(001) β2(4×2) reconstruction surface is smaller than that of As(P) rich one, and the work functions of Ga rich β 2 (4×2) and As(P) rich β2(2×4) surfaces are 4.657 eV and 5.187 eV, respectively. The adsorption energies of Cs adatoms on both surfaces are negative, showing that Cs adsorption is a stable exothermic process. The work functions of two surfaces both decrease after Cs adsorption, and the average variation of As(P) rich β2(2×4) surface is larger. Mulliken charge analysis shows that Cs adatoms transfer electrons to GaAsP substrate, resulting in Cs-GaAsP dioples which lower the work functions. When Cs atoms are located at D 2 of Ga rich surface and D 2 ' of As(P) rich surface, work function values of the two reconstruction surfaces reach the minimums, which are 2.834eV and 2.859eV, respectively. By calculating dipole moments, it can be found that Cs adatoms on the topmost layer form larger effective dipole moments with GaAsP substrate than the Cs atoms located in the trench.

Abstract
Potted plants have been reported to uptake VOCs and help ‘cleaning’ the air. This paper presents the results of a laboratory study in which two species of plants (Peace Lily and Boston Fern) and three kinds of substrates (expanded clay, soil and activated carbon) were tested and monitored on their capacity to deplete formaldehyde and CO2 in a glass chamber. Formaldehyde and CO2 were selected as indicators to evaluate the bio-filtration efficacy of 28 different test conditions; relative humidity (RH) and temperature (T) were monitored during the experiments. To evaluate the efficacy of every test the Clean Air Delivery Rate (CADR) was calculated. Overall, soil had the best performance in removing formaldehyde (~ 0.07–0.16 m3/h), while plants, in particular, were more effective in reducing CO2 concentrations (Peace lily 0.01m3/h) (Boston fern 0.02-0.03m3/h). On average, plants (~ 0.03 m3/h) were as effective as dry expanded clay (0.02–0.04 m3/h) in depleting formaldehyde from the chamber. Regarding air cleaning performance, Boston ferns presented the best performance among the plant species, and the best performing substrate was the soil.

Abstract
Background: Trisomy 18 syndrome (Edwards syndrome, ES) is a type of aneuploidy caused by the presence of an extra chromosome 18. Aneuploidy is the leading cause of early pregnancy loss, intellectual disability, and multiple congenital anomalies.Results: In this study, we used the commercial Chromium platform (10x Genomics) to perform sc-ATAC-seq to measure chromatin accessibility in 11,611 single umbilical cord blood cells derived from one trisomy 18 syndrome patient and one healthy donor. We obtained 13 distinct major clusters of cells and identified them as 6 human umbilical cord blood mononuclear cell types without using antibodies. We set out to generate a single-cell atlas of chromatin accessibility in human umbilical cord blood from the healthy control donor and the 18 trisomy syndrome donor. Then, we carried out cell-type-specific gene regulatory network analysis at single-cell resolution of these differential accessibility-related loci genes and summarized the disease-related transcription factors (TFs) and target genes. Finally, we performed a cell-type-specific gene regulatory network analysis of these differential accessibility-related locus genes at single-cell resolution.Conclusions: Specifically, CCBN2 and MCM3 may be essential for the development of trisomy 18, and genes differentially expressed between the donor and patient were enriched in the human T-cell leukaemia virus 1 infection pathway. These screened disease-related transcription factors (TFs) and their target genes provide a basis for further research that will improve our understanding of trisomy 18 syndrome.
Typha Latifolia L. Grown in Carrying Petroleum Secondary Effluent Supply Nutrients Enhance for Biomass Growth and Phytoremediation of Heavy Metals and TPH
Authors: Ahmad Anwar 
Published: April 2021

Abstract
Phytoremediation is an innovative tool which can be used for the treatment of industrial and agricultural wastewater. Typha latifolia L. (T. latifolia L) is an aquatic plant which grows on petroleum secondary effluent (PSE) containing metals like cadmium (Cd), cobalt (Co), manganese (Mn) and TPH (total petroleum hydrocarbon). The growth performance in biomass, nutrient concentrations and heavy metals in parts of the T. latifolia L. The reason for the accumulation of Cd, Co and Mn in T. latifolia L. can be explained as a tolerance strategy due to its transfer index (TI) which is higher than 2.9. The enrichment coefficients of the metals present in the root compared to stem of T. latifolia L. were higher than 3.31 to 2.56 for Cd, 5.35 to 3.55 Co. But, for Mn were found to be lower 1.98 than 3.51 at 75%. Similarly, the enrichment coefficients of all the metals, except for Co, in roots of T. latifolia L. were higher than 5.36. (TI) for Co (2.95) and Mn (2.55) which is absolutely better as compared to the enrichment coefficients of Cd (2.35) and TPH (3.45) in PSE. Thus, there is a possibility that PSE could be a source of important nutrients.

Authors: Sharma Dinesh Kumar , Tripathi Saurabh Mani 
Published: April 2021

Abstract
The advent of polymer (or plastic) optical fibers (POFs) with porous cross-section has contributed significantly to the sensing applications. We intend to explore the sensing attributes of polymer-based one-rod core microstructured optical fibers (P-MOFs) via utilizing an auxiliary approach. The sensitivity coefficient and the overlapping factor of P-MOF’s introduced design in air-filled and water-filled layouts against the structural parameters are exploited. We reported the overlapping factor of ~ 94% and ~ 82% for the said configurations of the fibers, respectively, at the wavelength of 0.633 µm. The confinement loss, mode-index, and effective mode-area are also evaluated for the anticipated structures. For assessing the confinement loss, an alternative approach based on double-clad fiber (DCF) approximation is employed. The validity of the simulated results is scrutinized with those as documented in the literature. Relative errors are also tabulated.

Additionally, the solubility in water and alkaline medium has been evaluated. The highest tack and peel adhesion increase was reported for PSA containing CMS with degree of substitution DS 0.86, to fax paper. Moreover, the dynamic shear strength test imitating the shear conditions in paper processing revealed, that the highest values of this parameters exhibited the system with 15 wt.% CMS DS 0.86. For this system the shortest water-dissolving times as well as at elevated pH were noted: 314 s and 60 s, respectively.
Optimized Degradation of Bisphenol A by UV/H2O2 coupled to Microwaves in a Novel Reactional Setup
Authors: Barrenha Pedro , Azevedo Eduardo Bessa 
Published: April 2021

Abstract
In this paper, the UV/H2O2/MW (microwave) process was compared with the UV/H2O2 one, using bisphenol A (BPA) as a model-pollutant. The proposed experimental setup was operated in batch recycle mode and allows for the direct comparison among different processes: UV only, H2O2 only, MW only, UV/H2O2, UV/MW, H2O2/MW, and UV/H2O2/MW, as well as temperature control to minimize thermal effects. The degradation of BPA at near-environmental concentration (100 µg L−1) was optimized by an experimental design approach (Response Surface Methodology) and its residual concentration was measured by HPLC. Approximately 95% of the initial BPA amount could be removed in 30 min at the optimal conditions (CH2O2 = 20 mg L−1, flow rate = 700 mL min−1, and MW power = 245 W). The experiments designed for comparing the UV/H2O2 and the UV/H2O2/MW processes showed that the use of MW doubled the initial pseudo-first-order degradation rate (from 0.046 to 0.10 min−1) and significantly increased the maximum oxidation capacity of the system (from 86 to 100%). Although the reasons behind those results are still unclear, it seems that the existence of non-thermal effects of the MW irradiation should be considered.

The study was performed by molecular dynamics simulations using three water models, being two non-polarizable 3-site SPC/E and SPC/e, and a novel flexible 3-site FAB/ model. Systematic thermodynamics, dynamical and dielectric properties were investigated, such as density, diffusion coefficient, heat of vaporization ∆Hvap, and surface tension at 300 K and 1 bar. We extrapolated the experimental molar fraction of the mixtures and a pattern change for all properties was observed, evidencing the phase separation previously reported by experimental data. The results also display the dielectric effect of the system on the calculated properties.

Published: April 2021

Abstract
Prior studies have noted that Zinc finger E-box binding homeobox 1 (ZEB1) is a master transcription regulator, affecting the expression of nearly 2,000 genes in breast cancer cells, especially in epithelial-mesenchymal transition (EMT) process. In this study, we found that ZEB1 directly regulated Glutathione peroxidase 4 (GPX4) transcriptions, which was closely related to tumor reactive oxygen species (ROS) metabolism. We selected two human breast cancer cell linesMDA-MB-231 and MCF7 for ROS test, PCR, immunofluorescence, western blot, ChIP, luciferase assay and enzyme assay. The conclusions continue to be supported in mouse models and bioinformatics analysis. We found that ZEB1 directly bound to GPX4 promoter E-box motif (CANNTG) to inhibit GPX4 transcription, which contributing to ROS accumulation and tumorigenesis in breast cancer.

Abstract
Regeneration is essential for vegetative propagation of excellent variety, detoxification, and obtaining transgenic plant. However, plant regeneration is time-consuming. We found that duckweed regeneration could be enhanced by regenerating callus. The molecular and VOCs releasing mechanisms underlying that have been studied here. Firstly, Genetic transcript regulation has been applied to study the molecular mechanism controlling regeneration. Auxin-related genes have been significantly down-regulated in regenerating callus. Cytokinin signal pathway genes have been up-regulated in regenerating callus. Secondly, VOCs release has been analyzed by GC/MS during the stage of plant regeneration, and 11 kinds of unique VOCs in the regenerating callus were increased. Among them, cyclohexane treatment enhanced duckweed regeneration by initiating root. Moreover, Auxin signal pathway genes were down-regulated in callus treated by cyclohexane. Altogether, these results provide novel mechanistic insights into how regenerating callus promotes duckweed regeneration.

Published: April 2021

Abstract
In this study, we described the successful identification of four mud crab species (genus Scylla) by high-resolution melting curve analysis (HRM) of single nucleotide polymorphisms (SNPs). The complete mitochondrion genome sequences of Scylla serrata, Scylla paramamosain, Scylla olivacea and Scylla tranquebarica were aligned and screened for distinct fragments. A single pair of primers were designed to amplify the 203-bp consensus amplicon. As a result, a total of 96 samples from the four mud crab species were clearly separated. The melting profiles from HRM analysis were found to be distinct across the species tested, and a number of 28 SNP sites were confirmed by sequencing. This new identification method will be a useful tool for discrimination of the four Scylla species and contribute to the effective breeding management of these species.
Is there an optimal place to hold the endotracheal tube during direct laryngoscopy? Protocol for a Randomised Controlled Trial
Authors: Sahoo Manisha , Tripathy Swagata , Mishra Nitasha 
Published: April 2021

Abstract
Background: Laryngoscopic endotracheal intubation (LEI) is a widely performed lifesaving technique. There are evidence and guidelines to help decide the optimal sized endotracheal tube (ET), laryngoscope, depth of insertion, and patient position for successful endotracheal intubation. We hypothesize that after glottic visualization, the point at which the ET is held will affect the time, ease, and success of the technique due to a difference in visualization and torque. We aim to compare two sites of holding the ET after optimal laryngeal-inlet visualization: time to intubation, rate of success of first pass intubation, intubation difficulty and complications.Methods: Supervised intubations on ASA 1-2 patients (>18 years) posted for surgery under general anesthesia performed by anesthesia trainees (experience <18 months) will be included. Patients with an anticipated difficult airway or unanticipated difficulty - CL grade > three or requiring the use of airway adjuncts will be excluded. A computer-generated numbers list will randomize patients; allocation concealed with opaque sealed envelopes. ET marked at the selected site will be handed to the intubator by the theatre-technician once she/he confirms the optimum laryngoscopic view. The entire procedure will be video recorded. Two blinded assessors will independently review the videos to document the time to intubation (TTI defined as the time from holding the ET to the removal of laryngoscope from the mouth after successful intubation) and intubation difficulty score. Postoperative sore throat and hoarseness will be recorded.Sample size: 54 experienced anesthetists were video-recorded during intubating. The site of holding ET and TTI were analyzed. The mean site was 3 SD 2.5 cm from the tip, yielding two sites for the study- 19 cm (Gr 1) and 24 cm (Gr 2). To detect a 20% difference in intubation time between groups, the confidence of 95%, and power 85%, we will need 298 patients: 180 per group after accounting for data loss.Discussion: This will be the first study to assess whether holding the tube at a particular site has any impact on the ease and time taken for intubation. This study's findings will provide the first scientific evidence for an appropriate place for holding the ET during LEI, which we feel will help trainees improve their LEI technique.Trial registration: CTRI/2019/09/021201, Clinical Trials Registry India. http://ctri.nic.in/Clinicaltrials/advsearch.php.
