Published: October 2022

Abstract
The "Three nitrogens" [Ammonia nitrogen (NH4 + -N), Nitrate nitrogen (NO3 − -N) and Nitrite nitrogen (NO2 − -N)] from industrial or domestic wastewater can lead to eutrophication of water bodies, ammonia The conversion of nitrogen into nitrate nitrogen will cause high nitrogen and oxygen demand (NOD), which will also lead to methemoglobinemia, and the high content of nitrite in the water body will increase the risk of cancer. In this paper, SiO2 aerogel is used as a carrier to synthesize Fe-Ce bimetal-doped composite materials (Fe-Ce/SiO2 and Fe-Ce-SiO2/TiO2) for the adsorption and degradation of "three nitrogens". The effect of metal Fenton reagent (Fe-Ce/SiO2) Fenton catalysis and photo-Fenton cooperative catalysis (Fe-Ce-SiO2/TiO2) on the degradation efficiency of "three nitrogens". SiO2/TiO2 was prepared by dipping method, and Fe and Ce bimetals were loaded on the surface of SiO2/TiO2 material, and the effect of photo-Fenton oxidation on the degradation rate of "three nitrogen" under different materials was explored. The results showed that: when the dosage of catalyst was 0.01 g, pH value was 11.0, and the concentration of H2O2 was 80 mmol/L, the photocatalytic efficiency was the best, and the degradation efficiency of "three nitrogen" remained above 70%.

Authors: TOMAR Pankaj 
Published: October 2022

Abstract

Nanotechnology is an emerging scientific domain for innovative application in biomedical, electronics, bio functionalities, tribology, and energy generation. Nano cellulose, carbon black, black carbon, carbon dots, and graphene family members are functional structures due to unique physiochemical properties and electron transfer efficacy. The transformation of physiochemical or morphological properties of carbon nanoparticles may lead to biological activities for evolution of reactive oxygen species. Disruption of biological membrane due to supramolecular adhesion of hydroxyl, carboxyl, and amino functional groups is a biomechanical mechanism of cytotoxicity of carbon nanomaterials. The surface tension and Gibbs free energy of bio-membrane is affected by the loading of carbon nanomaterials.

Published: October 2022

Abstract
Vitamins are a group of organic compounds needed in small quantities by the body to perform its essential functions like growing, regulating metabolism and maintain a healty immune system. In recent years, substantial efforts have been focused on development of simplified, fast and cost-effective approaches for vitamin analysis. Aim of this study was electrochemical detection of some water and fat-soluble vitamins individualy and simultaneously by using bare pencil graphite electrode (PGE). Vitamins of C, B1, B6, B12, A, D3, and E were selected and electrochemically analyzed in pharmaceutical preparates. Simultaneous analysis of water-soluble vitamins by using DPV with PGE can be promising technique for the determination of vitamin C and B6 or vitamin B1, B12 and B6. In the case of fat-soluble vitamins, resolution between vitamin D3 and E was not satisfactory. However, vitamin A and D or vitamin A and E could be detected in a single run. Limit of detection of the selected vitamins were quite low (4-548 µg/ml).
Molecular Mechanisms of Holliday Junction Branch Migration Catalyzed by an Asymmetric RuvB Hexamer
Authors: Fu Tian-Min , Rish Anthony , Shen Zhangfei , Chen Zhenhang 
Published: October 2022

Abstract
The Holliday junction (HJ) is a universal DNA intermediate of homologous recombination that is involved in many fundamental physiological processes. In bacteria, RuvB, a motor protein of the AAA+ ATPase superfamily, drives branch migration of the Holliday junction with a mechanism that had yet to be elucidated. Here, we report two cryo-EM structures of RuvB in complex with DNA and nucleotides, providing a comprehensive understanding of HJ branch migration. Six RuvB protomers assemble into a spiral staircase, in the shape of a ring, with DNA in the central pore. Four protomers of RuvB hexamer interact with the backbone of the DNA substrate, suggesting a pulling-and-revolving mechanism of DNA translocation with a basic step size of 2 nucleotides. Moreover, the variation of nucleotidebinding states in our RuvB hexamer supports a sequential model for ATP hydrolysis, ADP release, and ATP reloading, which occur at specific positions on the RuvB hexamer. Furthermore, the asymmetric assembly of RuvB also explains the 6:4 stoichiometry between RuvB and RuvA, which assembles into a complex to coordinate HJ migration in cells. Taken together, we provide a comprehensive framework for the mechanistic understanding of HJ branch migration facilitated by RuvB motor protein, which may be universally shared in both prokaryotic and eukaryotic organisms.

Abstract
The performance of an anoxic-oxic membrane bioreactor electrochemically assisted (A/O-eMBR) was assessed as an alternative for azo dye (Remazol Brilhant Violet -RBV) removal from textile wastewater. The A/O-eMBR was operated under three experimental conditions (runs I, II and III), in which different solids retention time (SRT) (45 and 20 d) and exposure mode to electric current (6´ON/30´OFF and 6´ON/12´OFF) were assessed. The reactor exhibited excellent performance on the decolorization process for all experimental conditions, with average dye removal efficiency ranging from 94.3 to 98.2%. Activity batch assays showed that the dye removal rate (DRR) decreased from 16.8 to 10.2 mg RBV L− 1 h− 1 when the SRT was reduced from 45 to 20 d. a behavior attributed to the lower biomass content under these conditions. When the exposure mode was 6 ON´/ 12´OFF, a more substantial decrease of DRR to 1.5 mg RBV L− 1 h− 1 was noticed, suggesting a possible inhibitory effect on dye removal via biodegradation. By reducing the SRT to 20 d, a worse mixed liquor filterability condition was observed, with a membrane fouling rate (MFR) of 0.979 kPa d− 1. In contrast, the use of electric current to exposure mode of 6 ON´/ 12´OFF resulted in lower membrane fouling propensity, with a MFR of 0.333 kPa d− 1. A more attractive cost-benefit ratio in terms of dye removal was obtained by using the exposure mode of 6´ON/30´OFF, for which the energy demand was estimated at 21.9–22.6 kWh kg dye− 1removed, 92–99% lower than that observed for the mode of 6´ON/12´OFF.

Abstract
Objective
To investigate the regulation and network mechanism of SCU on pyrodeath gene in diabetic retinopathy.
Methods
The animal model of DM was established and the retinopathy was observed by HE staining, Ni staining and immunofluorescence staining. The retinopathy of SCU group was significantly improved. DR gene, cell pyrophoric gene and astragaloside IV gene were queried, Venny intersection was performed, GO and KEGG analysis was performed, PPI protein interaction was performed, and Hub gene was screened for molecular docking verification.
Results
4084 genes related to DR were screened from GeneCards and OMIM databases. Using GeneCards, TCMSP and Swiss Target Prediction databases, 120 SCU therapeutic targets were obtained. Using GenenCards database, 357 targets related to coke decay were retrieved. Drug, disease and phenotypic targets were analyzed online using the Draw Venn Diagram website, and 12 cross targets were obtained. Through GO function and KEGG pathway enrichment analysis of common targets, 659 BP related items, 7 CC related items, 30 MF related items, and 70 signal pathways were screened out. Eleven proteins were screened to interact with the cross-target PPI network, and 11 proteins were subsequently docked with the SCU. The results show that SCU has good binding activity to the core.
Conclusion
SCU can regulate the death reaction of DR coke through multi-target and multi-pathway, and reveal its possible mechanism.
Does benefits-of-breastfeeding language or risks-of-formula-feeding language promote more-positive attitudes toward breastfeeding among nurses?
Authors: Toda Ayumi , Nanishi Keiko , Shibanuma Akira 
Published: October 2022

Abstract
Background. Nurses are crucial in helping new mothers to learn the necessary skills and overcome the difficulties of breastfeeding. Few studies have explored appropriate language for nursing education on breastfeeding. We assessed the impact of the language used on breastfeeding attitudes among Japanese nurses.
Methods. A quasi-experimental study was conducted online in Japan among 174 nurses who had work experience in obstetrics or pediatrics. Participants were allocated to three groups to receive different text messages as the intervention (the benefit of breastfeeding for Group 1; the risk of formula feeding for Group 2; the importance of childcare for Group 3 as the comparison). The Japanese version of the Iowa Infant Feeding Attitude Scale (IIFAS-J) was used to assess breastfeeding attitudes before and after reading the texts. Also, participant reactions to the text were assessed by their responses to three statements. ANOVA, the chi-square test, and the t-test were used for outcome assessments.
Results. The post-test IIFAS-J score was significantly higher than the pre-test score only for Group 1 (p < 0.01). The percentage of nurses who agreed with the content of the text was 70.7% in Group 1 and 48.3% in Group 2. The percentage of nurses who reported discomfort with the text was 34.5% in Group 1 and 55.2% in Group 2. No significant difference among groups existed regarding interest in the text. In all three groups, participants who agreed with the text had higher post-test IIFAS-J score than those who disagreed with the text (6.85 points higher, p < 0.01 in Group 1; 7.19 points higher, p < 0.01 in Group 2; 8.00 points higher, p < 0.02 in Group 3). Discomfort with the text and interest in the text were associated with higher post-test IIFAS-J score in Group 1 and Group 2 but not significantly associated in Group 3.
Conclusions. “Benefits of breastfeeding” language is suggested to be better than “risks of infant formula” language for producing a positive attitude to breastfeeding in nursing education.

Published: October 2022

Abstract
Searching for the precise solution of free surface has remained the main bottleneck in analyzing the unconfined seepage problem for earth-rock dams. To seek a tradeoff between searching efficiency and accuracy, and as a first attempt to explore the full impacts of seepage anomalies and its varying location on the multiple seepage parameters for the typical heterogeneity issues, this paper proposes a novel approach by combining the smoothed finite element method (S-FEM) and gradient smoothing technique (GST). Considering the practicality limitation due to huge calculation burden resulted from solving the internal integral of elements, the proposed method optimizes the shape functions calculation and explores the specific influence of division manner of smoothing cells on the computational efficiency and accuracy. To demonstrate the novelty and computational efficiency of the GST-based methodology, we performed a series classical model tests involving classic homogeneous and complicated inhomogeneous media models. We focused on the specific impacts of anomalies with varying degrees of permeability on the multiple parameters for seepage inversion, including water head, free surface solution, overflow point, seepage velocity and fluid pressure. The evidence implies that the significant influence of anomalies existence deserves high concern. More importantly, the results also demonstrate that our method improves the capacity of maintaining the high accuracy of seepage solutions with a preferable efficiency in handling the heterogeneous cases of earth dam, which provides great potential for developing multi-parameter seepage inversion, the accuracy of our GST-based seepage simulation is a significant step towards commercially-viable applications of multi-parameter seepage inversion.

Published: October 2022

Abstract
Introduction
The present study aimed to develop core competencies and Entrustable Professional Activities (EPAs) for faculty members through participating in faculty development courses in the field of medical ethics.
Methods
This study included five stages. First, based on the literature review and interviews with 14 experts and through inductive content analysis, categories and subcategories were extracted. Second, content validity of the core competency list was assessed by 16 experts using qualitative and quantitative approaches. Third, based on previous phase, a framework for EPAs was developed by research taskforce in two sessions through consensus. Fourth, content validity of the list of EPAs compiled based on three-point Likert was evaluated by 11 medical ethics experts from necessity and relevance perspective. Fifth, EPAs were mapped by 10 experts to the developed core competencies.
Results
After literature review and interviews, 295 codes were extracted, which were further classified into six categories and 18 subcategories. Based on the validation results, five core competencies and 23 EPAs were developed that were required for faculty members in the field of medical ethics. Identified core competencies included teaching, research and scholarship in the field of medical ethics, communication skills, moral reasoning, and decision-making, policy-making and ethical leadership.
Conclusion
Medical teachers can be strongly effective in moralizing healthcare system, and present findings showed that faculty members should acquire extensive core competencies and EPAs for proficiently integrating medical ethics in curricula. Faculty development programs can be designed in the field of medical ethics for faculty members to help them acquire core competencies and EPAs.

Abstract
Background
Globally 1 in 7 people experience some type of disability. In Latin America, as in other regions, there are programs focused on protecting sexual and reproductive rights. However, in Peru don’t exist programs, protocols, or guidelines that include a specialist (sexologist or trained health professional) in the health system, which allows for improving the quality of life and well-being of this population. Therefore, the study aims to analyze the experience of sexuality of people with motor disabilities to propose actions that contribute to improving their quality of life.
Methods
The interpretive phenomenological approach and the semi-structured in-depth interview with 60 questions were used, which was applied to 7 people (4 women and 3 men) with acquired motor disability.
Results
In this study observed diversity in the experience of sexuality. While some people experience it without fear; others have canceled their sexual activity. It could be because, in addition to physical limitations, they experience psychosocial limitations such as pain, functional alterations, depression, low self-esteem, discrimination, exclusion, stigma, socio-environmental barriers, etc. Therefore, the study reflected the double discrimination suffered by women (for being a woman and having a disability) and the absence of sexual education, counseling, or sexual therapy by specialized professionals. Other factors are the influence of religion, society, and culture that might condition and limit their sexuality. This reflects the current situation in Peru and other countries in the region, where the sexuality of persons with disabilities continues to be a complex and ambiguous issue.
Conclusions
The review of the profile and level of specialization of the health services professionals involved in the integral medical care of people with disabilities and their couples is required because of their need for adequate and specialized attention for their better adaptation to the new condition.

Authors: Iqbal Sana , Baig Sofia 
Published: October 2022

Abstract
Respirable Particulate Matter (RPM) in indoor microenvironments (MEs) is a major concern due to its health impacts along with the fact that people spend, on average, 70-80 % indoor. Therefore, in this study the exposure of students to RPM was monitored and analysed on main campus of a University during university working hours. A set number of students were selected and their exposure to RPM was monitored. Basically, Particulate Mass Concentration (PMC) and Particle Number Count (PNC) was monitored and analysed. calibrated air pump with nylon cyclone (size separation) and Dylos DC 1100 Pro (improvised for portability) was used for this purpose. Besides personal exposure, the PMC and PNC were also monitored in most frequently identified microenvironments separately. The correlation between PNC and PMC was investigated. We found that for a student personal exposure, the mean concentration of RPM was 251 µg/m3 and the relationship between PNC and PMC of microenvironment was found to be significantly correlated.

A rare confusing presentation carpal tunnel syndrome as first sign of Hypothyroidism and Rheumatoid arthritis: A case report
Authors: Harna Bushu , Arya Shivali 
Published: October 2022

Abstract
Introduction: Carpal tunnel syndrome (CTS) can be an initial sign of underlying undiagnosed disorders like hypothyroidism or rheumatoid arthritis. The erosive type of CTS is rare and generally requires carpal tunnel release surgery as a treatment modality Case: A 55-year-old gentleman presented with paraesthesia and spontaneous digital ulceration of the distal finger in both hands over 5 months. Initially managed as some vascular disorder by physicians. Later on, in nerve conduction studies, CTS was diagnosed. The patient was further investigated for etiology leading to the diagnosis of hypothyroidism and rheumatoid arthritis. These were managed with medications and CTS was managed with the surgical release. The paraesthesia was relieved post-surgically and digital ulceration healed over a few weeks. Conclusion: Digital ulcerations can be a presentation of CTS rather than vascular/vessel disorder. The physician should be aware of CTS erosive variety and further investigate the etiology like hypothyroidism, and rheumatoid arthritis. The etiological factors should be treated first before embarking on surgical carpal tunnel release.
Random Forest-based prediction of performance gap of the Clean Development Mechanism projects
Authors: Cho Haein 
Published: October 2022

Abstract
The performance of climate technology implemented under Clean Development Mechanism (CDM) is varied in terms of Certified Emission Reductions (CERs) issuance rate, a ratio of the actual CER issued of the total CER expected, ranged between 2% and 193%. In this study, we propose a novel approach for estimating the CER issuance rate (i.e., lower or higher than 100%) by using random forest algorithms. Unlike previous studies, we associate 1443 indicators related to economy, environment and society from 28 countries with the outcome of CER issuance rate of 3338 CDM projects and examine mixed effects of local context-driven indicators. Data preprocessing and feature selection techniques are applied to extract important indicators with which classification and prediction are conducted across different types of CDM technologies. The highest accuracy and F-measure of the developed prediction model are achieved from wind projects (84%, 92%, respectively). The obtained results exhibit possibilities of capturing the performance gap through machine learning algorithm. Moreover, we recommend adopting local demand-driven indicators to enhance the usability of the proposed approach.
